STATE BOARD OF REGISTRATION FOR THE HEALING ARTS, Appellant,
v.
Edward W. McDONAGH, D.O., Respondent.
No. SC 85275.
Supreme Court of Missouri, En Banc.
December 23, 2003.
Rehearing Denied January 27, 2004.
*148 Glenn E. Bradford, Edward F. Walsh, IV, Kansas City, MO, for Appellant.
Lori J. Levine, R. Max Humphreys, Daniel P. Card, II, Jefferson City, MO, for Respondent.
Mark G. Arnold, St. Louis, MO, for Amicus Cyriae Missouri State Medical Association, Missouri Association of Osteopathic Physicians and Surgeons.
LAURA DENVIR STITH, Judge.
The State Board of Registration for the Healing Arts (the Board) initiated a disciplinary complaint against Dr. Edward McDonagh primarily alleging that he violated *149 section 334.100,[1] a part of the Missouri Healing Arts Practice Act, through his representations regarding and use of chelation therapy in the treatment of patients with vascular disease. The Administrative Hearing Commission (AHC) found no cause to discipline Dr. McDonagh's medical license. The circuit court affirmed the AHC's decision. The Board appeals, alleging the AHC erred by failing to apply the standard for admission of expert testimony set out in Frye v. United States, 293 F. 1013 (D.C.Cir.1923), and that the testimony of Dr. McDonagh's experts should have been excluded.
This Court reaffirms its holding in Lasky v. Union Electric Co., 936 S.W.2d 797 (Mo. banc 1997), that the standard for the admission of expert testimony in civil cases is that set forth in section 490.065. As discussed herein, this is also the standard to be applied in administrative cases. To the extent that civil cases decided since Lasky apply Frye or some other standard, they are incorrect and should no longer be followed. Section 490.065.3 requires that the facts and data on which an expert relies must be those reasonably relied on by experts in the relevant field. Here, the relevant field is physicians treating persons with vascular disease. Because the AHC failed to properly apply this standard, this Court reverses the circuit court's judgment and remands the case. On remand, the circuit court should remand to the AHC for reconsideration of the AHC's decision in light of this standard.
This Court also remands for reconsideration of the issue whether Dr. McDonagh committed repeated negligence because his experts did not identify the standard of care by which they judged his treatment of his patients and it appears the AHC judged his conduct by reference to the treatment advocated by other doctors using chelation therapy. Under section 334.100.2(5), the AHC should have judged the conduct by the standard of care of those treating patients with vascular disease.
Because the principles stated herein may also affect the AHC's determination of the remaining issues regarding record keeping, testing, and misrepresentation, this Court remands the case in its entirety for reconsideration in light of this opinion.[2]
I. FACTUAL AND PROCEDURAL BACKGROUND
The Board is authorized by section 334.120.1 to register, license, and supervise physicians and surgeons practicing in Missouri. The Board licensed Dr. McDonagh, D.O., as an osteopathic physician and surgeon in 1961. Soon after becoming licensed, he began employing alternative medical treatments in his family practice, including EDTA[3] chelation therapy to treat atherosclerosis and other diseases. He also became certified by the American Board of Chelation Therapy, and has conducted research and written extensively on the use of this therapy.
A. Regulation of Chelation Therapy by the Board.
Chelation therapy has been approved by the federal Food and Drug Administration (FDA) only as a means for the removal of *150 heavy metals from the body. However, non-FDA-approved, or "off-label," use of medications by physicians is not prohibited by the FDA and is generally accepted in the medical profession. See 21 U.S.C. Sec. 396 (2000); Buckman Co. v. Plaintiffs' Legal Comm., 531 U.S. 341, 350-51 & n. 5, 121 S.Ct. 1012, 148 L.Ed.2d 854 (2001). Approximately 1,000 physicians in the United States engage in the off-label use of chelation therapy to treat atherosclerosis and other vascular conditions.[4] Of these 1,000 United States-based physicians, 750 belong to the American College for Advancement in Medicine (ACAM), which has 1,000 members worldwide and which endorsed chelation therapy as a valid course of treatment for occlusive vascular and degenerative diseases associated with aging.[5] To that end, ACAM developed a protocol, followed by Dr. McDonagh, for using chelation therapy to treat such diseases.
In 1989, the Board made an in-depth study of the efficacy of chelation therapy, but did not thereafter adopt any rules, regulations, or position papers on the use of this therapy. Then, in 1992 and 1994, two controlled studies were published that suggested that chelation therapy was ineffective in treating vascular disease.[6] Dr.
McDonagh disputes the validity of these studies. But, after the publication of the studies, the American Medical Association (AMA) adopted a position statement on chelation therapy, declaring that: "(1) [t]here is no scientific documentation that the use of chelation therapy is effective in the treatment of cardiovascular disease, atherosclerosis, rheumatoid arthritis, and cancer"; (2) chelation therapy proponents should conduct controlled studies and adhere to FDA research guidelines if they want the therapy to be accepted more broadly; and (3) "[t]he AMA believes that chelation therapy for atherosclerosis is an experimental process without proven efficacy." AMA, AMA Policy Compendium H-175.994, H-175.997 (1994).
In spite of these developments, neither the FDA, the AMA, or the Board banned the use of chelation therapy to treat vascular disease, and Dr. McDonagh continued to prescribe and administer the therapy in his practice.
Effective October 30, 2001, the Board adopted a rule stating that chelation therapy was of no medical value but that it would not seek to discipline a physician for using it on a patient from whom appropriate informed consent is received:

*151 (1) Pursuant to authority granted to the board by section 334.100.2(4)(f), RSMo, the board declares the use of ethylinediaminetetracetic acid (EDTA) chelation on a patient is of no medical or osteopathic value except for those uses approved by the Food and Drug Administration (FDA) by federal regulation.
(2) The board shall not seek disciplinary action against a licensee based solely upon a non-approved use of EDTA chelation if the licensee has the patient sign the Informed Consent for EDTA Chelation Therapy form, included herein, before beginning the non-approved use of EDTA chelation on a patient.
4 CSR 150-2.165.
B. Complaints Against Dr. McDonagh.
In 1994, seven years prior to the adoption of 4 CSR 150-2.165, and shortly after the two noted controlled studies, the Board filed a complaint against Dr. McDonagh arising out of two inquiries regarding his use of chelation therapy. This complaint was later dismissed without prejudice. In 1996, the Board filed a thirteen-count complaint alleging cause to discipline Dr. McDonagh's medical license for violating section 334.100[7] by, among other things: endangering the health of patients through the inappropriate provision of chelation therapy; misrepresenting the efficacy of this therapy for atherosclerosis and other diseases; conducting unnecessary testing and treatment in some instances, and insufficient testing and treatment in others; and failing to maintain adequate medical records.[8]
Dr. McDonagh denied that his treatments endangered his patients, denied using inappropriate testing or treatment, and denied inadequate record keeping. He also denied making misrepresentations to patients, noting that, prior to receiving chelation therapy, his patients signed a consent form explaining the possible benefits and side effects of the treatment (very similar to that later approved in 4 CSR 150-2.165), and stating that the treatment was not approved by the FDA, the AMA, or other recognized medical organizations for the treatment of vascular disease. In addition to chelation therapy, Dr. McDonagh encouraged patients to follow a diet and exercise plan, and did not discourage patients from seeing other physicians, including specialists.
The AHC held a hearing in November 1997. The Board introduced expert testimony that the use of chelation therapy to treat vascular disease is not generally accepted in the field of treatment of vascular disease and does not meet the standard of care for treatment of vascular disease. Dr. McDonagh offered expert testimony that supported his off-label use of chelation therapy to treat vascular disease. The Board objected. The AHC heard all of the evidence without ruling on its admissibility, as permitted by section 536.070(7), which provides that evidence subject to an objection "nevertheless be heard and preserved in the record." The AHC ultimately ruled that the testimony was admissible, found no evidence of harm from chelation therapy, rejected all thirteen counts, and found no cause to discipline Dr. McDonagh's medical license.
The circuit court affirmed the AHC's decision. The Board appealed. Following opinion by the Missouri Court of Appeals, Western District, this Court granted *152 transfer to address the standards for admission of expert testimony in civil and administrative cases. Mo. Const. art. V, secs. 10, 18.
II. STANDARD OF REVIEW
On appeal, this Court reviews the AHC's decision, rather than that of the trial court, to determine whether the agency action:
(1) Is in violation of constitutional provisions;
(2) Is in excess of the statutory authority or jurisdiction of the agency;
(3) Is unsupported by competent and substantial evidence upon the whole record;
(4) Is, for any other reason, unauthorized by law;
(5) Is made upon unlawful procedure or without a fair trial;
(6) Is arbitrary, capricious or unreasonable;
(7) Involves an abuse of discretion.
Sec. 536.140.2; Sec. 621.145; Psychcare Mgmt., Inc. v. Dep't of Soc. Servs., Div. of Med. Servs., 980 S.W.2d 311, 312 (Mo. banc 1998). Here, the Board argues that the decision was not "supported by competent and substantial evidence upon the whole record" and that "it was arbitrary, capricious, unreasonable or an abuse of discretion." Ross v. Robb, 662 S.W.2d 257, 259 (Mo. banc 1983). A reviewing court will refrain from substituting its judgment for that of the AHC on factual matters. Psychcare Mgmt., Inc., 980 S.W.2d at 312. Questions of law are matters for the independent judgment of this Court. Gammaitoni v. Dir. of Revenue, 786 S.W.2d 126, 128 (Mo. banc 1990).
III. STANDARD FOR ADMISSIBILITY OF EXPERT TESTIMONY
A. Section 490.065 Provides the Standard for Admission of Expert Testimony in Civil Actions.
The Board suggests the standard for admission of expert testimony is that set out in Frye and previously applied by this Court. See Alsbach v. Bader, 700 S.W.2d 823, 828-30 (Mo. banc 1985). Frye states that, for expert testimony to be admissible, "the thing from which the [expert's] deduction is made must be sufficiently established to have gained general acceptance in the particular field in which it belongs." 239 F. at 1014.
Dr. McDonagh counters that, although this Court once adopted the Frye test, the relevant standard for admission of expert testimony is now either that set forth by the Supreme Court of the United States in Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993), for application in the federal courts, or that set out in section 490.065. The latter statute says:
1. In any civil action, if scientific, technical or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education may testify thereto in the form of an opinion or otherwise.
2. Testimony by such an expert witness in the form of an opinion or inference otherwise admissible is not objectionable because it embraces an ultimate issue to be decided by the trier of fact.
3. The facts or data in a particular case upon which an expert bases an opinion or inference may be those perceived by or made known to him at or before the hearing and must be of a type reasonably relied upon by experts in the field *153 in forming opinions or inferences upon the subject and must be otherwise reasonably reliable.
4. If a reasonable foundation is laid, an expert may testify in terms of opinion or inference and give the reasons therefor without the use of hypothetical questions, unless the court believes the use of a hypothetical question will make the expert's opinion more understandable or of greater assistance to the jury due to the particular facts of the case.
Although section 490.065 on its face states that it applies in civil actions and sets out the relevant standard for admission of expert testimony in such actions, various decisions of Missouri's court of appeals since section 490.065 was enacted in 1989 have expressed confusion as to whether it is the statute, Frye, or Daubert that supplies the relevant standard for admission of expert testimony.[9]
Any such confusion should have been resolved by this Court's 1997 decision in Lasky holding that section 490.065 provides the applicable standard "in evaluating the admission of expert testimony" in civil cases. 936 S.W.2d at 802. While Lasky did not further expressly state that to the extent that prior civil cases applied a different rule they should no longer be followed, such a holding was implicit in Lasky's direction that "on remand the trial court shall be guided by section 490.065, RSMo, in evaluating the admission of expert testimony." Id. at 801.
To clarify, however, this Court expressly holds that to the extent that cases since Lasky have suggested that the standard of admissibility of expert testimony in civil cases is that set forth in Frye or some other standard, they are no longer to be followed. The relevant standard is that set out in section 490.065.
B. Section 490.065's Applicability to Contested Administrative Proceedings.
The Board alternatively argues that because the first four words of section 490.065 are "in any civil action," the standard for admission of expert testimony it sets out could have no application to administrative *154 actions such as this one. In support, the Board cites cases that have noted that administrative actions generally are tried in accordance with various rules of administrative procedure rather than in accordance with Missouri's rules of civil procedure, except to the extent that the latter have been adopted by statute for use in administrative cases. See, e.g., Wheeler v. Bd. of Police Comm'rs of Kansas City, 918 S.W.2d 800, 803 (Mo.App. W.D.1996); Dillon v. Dir. of Revenue, 777 S.W.2d 326, 329 (Mo.App. W.D.1989). The admission of expert testimony is not determined by rules of civil or administrative procedure, however, but by principles governing the admissibility of evidence. The relevant evidentiary principles are not set out in any set of rules, but rather have been developed by common law and by statute.[10] These principles govern the admission of evidence in civil and criminal cases.
Cases brought before administrative agencies generally are less formal and structured than are civil proceedings in the circuit courts. That does not mean that evidentiary rules developed in civil cases have no application to administrative actions, however. To the contrary, the legislature has specifically directed that many evidentiary principles developed in civil actions be applied in administrative ones, including those regarding privilege, judicial notice, admission of writings and documents, depositions, and so forth.[11]
This Court has further held that other, basic principles of evidence also apply in administrative proceedings. Thus, in Missouri Church of Scientology v. State Tax Commission, 560 S.W.2d 837, 839 (Mo. banc 1977), this Court stated, "[a]lthough technical rules of evidence are not controlling in administrative hearings, fundamental rules of evidence are applicable." The principle set out in Missouri Church of Scientology reiterates a principle this Court recognized at least as long ago as State ex rel. De Weese v. Morris, 359 Mo. 194, 221 S.W.2d 206, 209 (1949), in which this Court stated, "[t]he fact that technical rules of evidence do not control has been considered to permit of leading questions and other informalities but not to abrogate the fundamental rules of evidence." See also State ex rel. Bond v. Simmons, 299 S.W.2d 540, 545 (Mo.App.1957) (accord).
The approach set out in these cases applies here. While contested administrative proceedings are not required to follow the "technical rules of evidence," the "fundamental rules of evidence" applicable to civil cases also are applicable in such administrative hearings. See Mo. Church of Scientology, 560 S.W.2d at 839; De Weese, 221 S.W.2d at 209. The standards for admission of expert testimony constitute *155 such a fundamental rule of evidence. The standards set out in section 490.065 therefore guide the admission of expert testimony in contested case administrative proceedings such as this one.
C. Comparison of Section 490.065 with FRE 702, FRE 703, and Daubert.
The parties and the AHC seem to assume that section 490.065 and FRE 702 and FRE 703, as interpreted in Daubert, are effectively identical, and that the standard set out in section 490.065 mirrors that Daubert adopted for use in the federal courts.
Daubert held "[t]hat the Frye test was displaced by the [Federal] Rules of Evidence." 509 U.S. at 589, 113 S.Ct. 2786. It found that FRE 702 provides a more "flexible" standard for admissibility focused on "the scientific validity and thus the evidentiary relevance and reliability of the principles that underlie a proposed submission." Id. at 594-95, 113 S.Ct. 2786 (noting that "[t]he focus ... must be solely on principles and methodology, not on the conclusions that they generate").
Daubert set out a non-exclusive list of factors for consideration in determining whether the evidence in question meets the flexible standard, including: (1) "whether [the theory or technique] can be (and has been) tested"; (2) "whether the theory or technique has been subjected to peer review and publication"; (3) "the known or potential rate of error"; and (4) "`general acceptance.'" Id. at 593-94, 113 S.Ct. 2786.
The Supreme Court summarized its holding by emphasizing the difference between Daubert and the Frye test that the federal courts had previously employed, stating: "`General acceptance' is not a necessary precondition to the admissibility of scientific evidence under the Federal Rules of Evidence...." Id. at 597, 113 S.Ct. 2786.
Few cases have interpreted section 490.065. To the extent that section 490.065 mirrors FRE 702 and FRE 703, as interpreted and applied in Daubert and its progeny, the cases interpreting those federal rules provide relevant and useful guidance in interpreting and applying section 490.065. See Giddens v. Kansas City S. Ry. Co., 29 S.W.3d 813, 820 (Mo. banc 2000) ("The construction given by the federal courts to their rules does not control the interpretation of our state rules, even if the rules themselves are nearly identical. However, the experiences of those courts in applying rules similar to our own are illustrative"). To the extent that the two approaches differ, however, the standard set out in section 490.065 must govern.
The standard set out in section 490.065 is very similar to that initially adopted by the federal courts in Daubert and set out in FRE 702. Indeed, at the time Daubert was decided, FRE 702 was identical to section 490.065.1, stating, "If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise," except that section 490.065.1 added a preliminary phrase "[i]n any civil action."[12]
*156 While the parties presume that section 490.065.3 is also effectively identical to FRE 703, review of the two rules reveals important differences. Section 490.065.3 begins by stating, "The facts or data in a particular case upon which an expert bases an opinion or inference may be those perceived by or made known to him at or before the hearing." The first sentence of FRE 703 is identical except for minor stylistic variations.
But, section 490.065.3 goes on to require that the facts or data on which an expert bases an opinion or inference "must be of a type reasonably relied upon by experts in the field in forming opinions or inferences upon the subject" and that these facts and data "must be otherwise reasonably reliable." Sec. 490.065.3. Thus, section 490.065.3 expressly requires a showing that the facts and data are of a type reasonably relied on by experts in the field in forming opinions or inferences upon the subject of the expert's testimony. The court must also independently assess their reliability. Id.
By contrast, under FRE 703 whether the facts or data relied upon are "of a type reasonably relied upon by experts in the particular field in forming opinions or inferences upon the subject" is relevant only to determine whether the facts or data must be otherwise admissible in evidence. For this reason, unlike in Missouri, Daubert held that in the federal courts an expert need not necessarily identify the relevant scientific community, or field, in which the data and facts are accepted. Daubert, 509 U.S. at 594, 113 S.Ct. 2786.
IV. APPLICATION OF SECTION 490.065 TO DR. McDONAGH'S EXPERTS
The differences between section 490.065 and FRE 703 as interpreted in Daubert take on great importance here because a key area of disagreement of the parties concerns identification of the relevant scientific field by which Dr. McDonagh's practices are to be judged. This is essential because the statute requires that to be admissible expert opinion must be based on facts or data of a type reasonably relied upon by "experts in the field."
A. Identification of Relevant Field of Experts.
Dr. McDonagh argued, and the AHC appeared to determine, that the relevant "field" for purposes of this inquiry is the universe of medical practitioners who utilize chelation therapy. And, as the record shows that Dr. McDonagh followed the protocol for use of chelation therapy approved by the approximately 1,000 doctors who are organized into ACAM, it concluded that his experts' testimony as to whether his treatments were appropriate was admissible. But, to limit the relevant "field" to only those doctors who have already expressed their view that the therapy in question is appropriate would make the inquiry into acceptance by experts in the field pointless, for, by definition, only those who had accepted the therapy would be asked for their opinion.
The relevant field must be determined not by the approach a particular doctor chooses to take, but by the standards in the field in which the doctor has chosen to practice. As relevant here, Dr. McDonagh chose to treat patients with vascular disease. The Board's claim is that Dr. McDonagh engaged in repeated negligence or misrepresentation and was otherwise in violation of the relevant statutes in his provision of chelation therapy for these patients. Therefore, the relevant field is doctors treating persons with vascular disease. The facts or data on which Dr. McDonagh's experts rely, therefore, *157 must be those perceived by them at trial or must be of a type reasonably relied on by doctors treating vascular disease.[13]
By so stating, this Court is not in effect readopting the Frye standard under another name. Nothing in section 490.065 suggests that the conclusions reached in reliance on these facts and data must be in conformity with the general medical consensus or must be generally accepted. As under Daubert and cases applying it, such acceptance is but one factor of the relevant inquiry. Section 490.065.3 simply requires the court to consider whether the facts and data used by the expert are of a type reasonably relied on by experts in that field or if the methodology is otherwise reasonably reliable. If not, then the testimony does not meet the statutory standard and is inadmissible.
B. Necessity of Controlled Studies.
The Board argues that, even if Daubertfor which section 490.065 [14] is interpolatedprovides the standards for admission of expert testimony, the testimony of Dr. McDonagh's experts should have been excluded because controlled studies supporting use of chelation therapy to treat vascular disease do not exist.
Nothing in section 490.065 expressly requires such studies. The Board cites to no case decided under section 490.065 requiring that an expert opinion be supported by controlled studies in order to be admissible. To the contrary, section 490.065.3 states that an expert's opinion is admissible if the facts or data on which the opinion is based are "of a type reasonably relied upon by experts in the field in forming opinions or inferences upon the subject" and are "otherwise reasonably reliable." Controlled studies are a form of data. Therefore, the admissibility of an expert's opinion depends not on some immutable, external standardsuch as the presence of controlled studiesbut on whether experts in the particular field can reasonably rely on other types of data in forming their opinions, or whether in that field controlled studies are required. But, the AMA has suggested that controlled studies must be done before chelation therapy will be generally recognized as effective. See AMA, AMA Policy Compendium H-175.994 (1994) supra. Of course, section 490.065.3 also imposes an independent duty on the court to determine whether the facts and data relied on are otherwise reasonably reliable. The lack of controlled studies presumably would be relevant, but not necessarily dispositive, in making this determination. This is consistent with the approach under Daubert and FRE 703. Daubert says that whether the theory is or can be tested as a controlled study would dois merely one factor, albeit an important one, in determining its admissibility. 509 U.S. at 593-94, 113 S.Ct. 2786.
As applied here, it was up to the AHC to consider Dr. McDonagh's experts' testimony, along with the other evidence offered on the issue, and determine whether experts in the field could reasonably rely on the data those experts relied on in reaching *158 their conclusions about the use of chelation therapy. Because of the confusion in the cases in regard to the standard for admission of expert testimony, the AHC did not apply these standards in evaluating the expert testimony offered. On remand, the AHC may permit the parties to supplement the record with additional expert testimony addressing the issues relevant under the statute.
V. REMAINING ISSUES ON APPEAL
A. Necessity of Expert Testimony on Standard of Care for Repeated Negligence Under Section 334.100.2(5).
The Board alternatively argues that, even were the testimony of Dr. McDonagh's experts otherwise admissible under the relevant evidentiary standard, it was insufficient to counter the Board's allegations in various counts, and through expert and other evidence, that Dr. McDonagh's use of chelation therapy constituted "repeated negligence" as that term is used in section 334.100.2(5).[15] That section defines "repeated negligence" as "the failure, on more than one occasion, to use that degree of skill and learning ordinarily used under the same or similar circumstances by the member[s] of the applicant's or licensee's profession." Sec. 334.100.2(5).
The Board submits that, in order to counter the Board's experts, Dr. McDonagh's experts needed to testify as to whether he used the degree of skill and learning ordinarily used by members of his profession. But, while his experts testified that his treatment of his patients met "the standard of care," they never identified that standard of care. The Board argues that the standard of care he met must be the standard of care generally accepted in the profession, and this means that Dr. McDonagh is negligent if he treats his patients in a way other than the treatment generally offered by doctors in the field. And, given Dr. McDonagh's experts' admission that mainstream doctors generally do not use chelation therapy to treat vascular disease, the Board suggests, Dr. McDonagh's experts cannot have used the correct standard of care in giving their opinion that his treatment met the required standard.
Dr. McDonagh admits that his experts did not state by what standard of care they were evaluating his treatment of his patients, but argues, to the extent testimony as to the standard of care was necessary,[16] the standard is that used by *159 doctors who apply chelation therapy. In effect, he argues that, because he used the protocol approved by ACAM, he could not be found to be negligent and necessarily met the requisite standard of care.
Neither party's argument is correct. The relevant standard of care is neither a reformulation of the Frye general acceptance test, nor blind acceptance of the views of a subgroup of treaters. The relevant standard of care for discipline for repeated negligence is necessarily that set out in the statute addressing that conduct, section 334.100.2(5). That standard, similar to Missouri's standard for proof of negligence in civil cases,[17] requires a showing whether the doctor showed the "skill and learning ordinarily used under the same or similar circumstances by the member[s] of [the doctor's] profession." Sec. 334.100.2(5) (emphasis added). As the issue here is the treatment of persons with vascular disease, the appropriate standard of care is that used by doctors treating persons with vascular disease.
Application of this standard does not merely require a determination of what treatment is most popular. Were that the only determinant of skill and learning, any physician who used a medicine for off-label purposes, or who pursued unconventional courses of treatment, could be found to have engaged in repeated negligence and be subject to discipline. This would not be consistent with section 490.065.
Rather the statute requires only what it saysthat Dr. McDonagh use that degree of skill and learning used by members of the profession in similar circumstances. By analogy, one doctor may use medicine to treat heart problems while another might chose to perform a by-pass and a third to perform angioplasty, yet all three may be applying the requisite degree of skill and learning. That they came to differing conclusions by applying that skill and learning does not make one negligent and one non-negligent.
So too, here, if Dr. McDonagh's treatment, including his use of a diet and exercise regimen, and the lack of evidence of harm from his approach, demonstrates the application of the degree of skill and learning ordinarily used by members of his profession, then it is not a basis for discipline under the statute, even if other doctors would apply these facts to reach a different result.
Because, in concluding that Dr. McDonagh did not violate section 334.100.2(5), the AHC relied on Dr. McDonagh's experts' testimony and because this testimony failed to establish whether the experts were using the legal standard of care for "repeated negligence" set out in section 334.100.2(5), this Court must reverse and remand. The circuit court should remand to the AHC for reconsideration under section 490.065 and in light of the standard of care contained in section 334.100.2(5).
B. Record Keeping, Testing, and Misrepresentation Issues.
The parties dispute the AHC's findings and conclusions on the allegations that Dr. McDonagh failed to keep and maintain adequate records. These allegations were made as part of Counts II, III, IV, V, X, and XII, rather than set out in an independent count, and the Board presented expert testimony on Dr. McDonagh's record-keeping practices in regard to the *160 standard of care. While the AHC made an independent finding that "no Missouri law or regulation sets forth standards or recommendations,"[18] it failed to consider the evidence as a component of the repeated negligence counts in which the allegations of inadequate record keeping arose. It should do so on remand.
The Board and Dr. McDonagh also dispute the AHC's findings regarding the Board's allegations of misrepresentation, and his alleged repeated ordering of inappropriate and unnecessary testing of patients. These issues should be remanded to the AHC for reconsideration in light of this opinion.[19]
VI. CONCLUSION
Because the expert testimony upon which the AHC relied failed to furnish the appropriate legal standard of care, the circuit court's judgment is reversed, and the case is remanded. On remand, the circuit court is directed to remand to the AHC on all counts for further review in light of section 490.065 and in light of the standard of care set out in section 334.100.2(5) and this opinion.
WHITE, C.J., BENTON, PRICE, TEITELMAN and LIMBAUGH, JJ., concur.
WOLFF, J., concurs in part and dissents in part in separate opinion filed.
WOLFF, Judge, concurring in part and dissenting in part.
I concur that section 490.065 sets the standards for admissibility and use of expert testimony. Because I believe that the Administrative Hearing Commission was correct in concluding that Dr. McDonagh was not subject to discipline for any of the acts alleged by the State Board of Registration for the Healing Arts, I would affirm the commission's decision, as the circuit court did.
I write separately to offer advice to lawyers on expert witnesses and gentle advice for the board on the future of this case against Dr. McDonagh.
Advice for Lawyers on Expert Witnesses
The principal opinion's discussion of section 490.065 is worth reading for its excellent legal analysis. I would only add a helpful summary for practitioners in Missouri courts and administrative agencies:
Forget Frye. Forget Daubert. Read the statute. Section 490.065 is written, conveniently, in English.[1] It has 204 words. Those straightforward statutory words are all you really need to know about the admissibility of expert testimony in civil proceedings. Section 490.065 allows expert opinion testimony where "scientific, technical or other specialized knowledge will assist the trier of fact..."[2]
*161 Dr. McDonagh and the physicians he called as expert witnesses surely were "qualified" as experts by "knowledge, skill, experience, training, or education...." The board argued that these witnesses' testimony was inadmissible under Frye v. United States, 293 F. 1013 (D.C.Cir.1923). Frye was remarkably beside the point.
Neither party gave the statute due regard. The board conceded that the testimony of Dr. McDonagh and his experts was admissible under section 490.065 but inadmissible under Frye. Why would an 80 year old federal court of appeals case trump a Missouri statute directly on point?
Dr. McDonagh argued, by contrast, that the applicable standard was that of Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993). Again, why would a Missouri statute directly on point be disregarded in favor of a United States Supreme Court decision on the Federal Rules of Evidence, which have not been adopted in Missouri?
What I think the parties are trying to get to is the relevant standard of care, discussed in the principal opinion. There is a problem here: in the proceedings before the commission, the board raised only the general objection that Dr. McDonagh's expert evidence would not qualify under Frye. The board did not object to any specific testimony from Dr. McDonagh or his experts. The board also did not raise the point it now presses in this appeal that Dr. McDonagh's experts did not define the standard used when they stated that his use of chelation therapy was in accord with the "standard of care." The board's evidentiary motion before the commission made no reference to "standard of care," nor did the board take the opportunity to cross-examine Dr. McDonagh's expert witnesses as to the standard of care. It was not Dr. McDonagh's burden to establish the relevant standard of care.
But the question of "standard of care" may be beside the point, as I will discuss in the next section in offering advice to the board.
Advice for the Healing Arts Board
The board should drop this case. It should not waste another dollar of public money on its case against Dr. McDonagh.
The board's case against Dr. McDonagh is premised on its contention that Dr. McDonagh's use of chelation therapy constitutes repeated negligence for which he should be disciplined. The board lost its case before the administrative hearing commission and then appealed to the circuit court, where it also lost.
Less than a month after the board filed its notice of appeal in 2001, the board promulgated a rule, 4 CSR 150-2.165, that declares the use of chelation on a patient is of "no medical or osteopathic value" except for such uses as approved by the federal Food and Drug Administration (FDA). The rule also says that the board "shall not seek disciplinary action" against a licensee where the licensee uses a patient consent form prescribed by the rule.
*162 The board concedes, and the principal opinion appropriately notes, that the consent form that Dr. McDonagh has used for many years is very similar to the consent form in the board's rule.
How can the board take the position that Dr. McDonagh's practice was repeatedly negligent under the disciplinary statute, section 334.100, when the board has a rule saying that it will not seek discipline against physicians engaging in this practice? What, exactly, is the standard of care?
The real question is: Is the healing arts board's use of section 334.100, which prescribes discipline for repeated acts of "negligence," an inappropriate use of the disciplinary process to impose the board's sense of orthodoxy?[3]
Dr. McDonagh's use of chelation therapy to treat atherosclerosis and other vascular diseases may be unorthodox. None of the mainstream medical organizations endorse its use for vascular diseases. But, until 2001after the acts the board complains of in this proceedingthere was no law or regulation regulating its use. Chelation therapy, which consists of administering the drug EDTA intravenously, is standard treatment for removal of heavy metals from the body. The FDA approves the chelation therapy medications for this use. Its use in attempting to clear vascular blockage is called an "off-label" use, referring to the use of a standard therapy for another purpose. There are many off-label uses of medicines that are generally accepted by the medical profession.
An organization called the American College for Advancement in Medicine, consisting of about 1,000 physicians worldwide including Dr. McDonagh, endorses the off-label use of chelation therapy, along with various vitamins and minerals, for treating vascular disease.
The administrative hearing commission heard evidence for eight days on the board's complaint against Dr. McDonagh for his use of chelation therapy and related matters.[4] The commission, in its 70 pages of findings of fact and conclusions of law, found no cause for discipline.
Specifically responding to the board's position that the use of chelation therapy is cause for discipline, the commission concluded: "It is not an unnecessary, harmful or dangerous treatment." The commission characterized McDonagh's conduct as "giving *163 patients a treatment that has provided benefit to many patients, harms no one, and is given with informed consent and the information that this treatment may not work with all patients." The commission further stated, "[T]he evidence shows that patients are being helped. We cannot state that an entire treatment method that provides benefits to patients without harming them constitutes incompetent, inappropriate, grossly negligent, or negligent treatment. Nor can we say that this treatment is misconduct, unprofessional, or a danger to the public."
The commission, based on the record, does acknowledge that chelation therapy involves risks, as of course do other treatments for vascular disease, such as coronary artery surgery. The risks of chelation therapy are disclosed, according to the commission, in the informed consent form that Dr. McDonagh has used with all his patients. The form gives notice that chelation therapy for vascular disease is not approved by the FDA, the American Medical Association, or others. It lists possible benefits, but also notes "you may not receive all of these benefits as they do not occur predictably with every patient and in some cases may not occur at all." Dr. McDonagh tells his patients that "the treatment will work better if the patient follows the diet, exercise and nutritional supplements that are recommended," according to the commission's findings.
There are scientific studies discussed in the commission's findings as to the efficacy of chelation therapy for vascular conditions. The mainstream organizations accept the conclusions of studies that found no value in treating vascular disease by chelation therapy. Dr. McDonagh and other like-minded physicians, including their American College for Advancement in Medicine, cite case reports and studiesarguably of less validity than the studies relied upon by the mainstream that show benefits in such use of chelation therapy.
There is a provision of section 334.100 that would seem to cover unorthodox treatments that are of no value. Section 334.100.4(f) provides for discipline where a licensee performs or prescribes "medical services which have been declared by board rule to be of no medical or osteopathic value." But the board did not have a rule against chelation therapy that would apply to Dr. McDonagh's acts, which occurred from 1978 to 1996. The board, long after the acts included in its complaint against Dr. McDonagh, promulgated a rule relating to chelation therapy, 4 CSR 150-2.165 (Effective October 30, 2001), quoted in full in the principal opinion.
More to the point, when the board finally promulgated its rule that declares chelation therapy to be "of no medical or osteopathic value," the board's rule goes on to provide that the board "shall not seek disciplinary action against a licensee based solely upon a non-approved use of EDTA chelation if the licensee has the patient sign" the informed consent form that accompanies the regulation. As noted here and in the principal opinion, the consent form that Dr. McDonagh used for these patientslong before the consent form promulgated by the boardis very similar to the consent form accompanying the 2001 rule.
At this point, the question becomes: what's going on here? In fairness to the board, I should note that the hearing before the administrative hearing commission in Dr. McDonagh's case was held in 1997, four years before the board promulgated its rule. But it seems strange that the board, having lost in the commission and in the circuit court, would press its claims on appeal after publishing the 2001 rule that undercuts its position.
*164 As to the board's claims heard in 1997 that are the subject of this appeal, it appears that the absence of a rule left the board to proceed against Dr. McDonagh under 334.100.2(5) for repeated acts of negligence. The board's complaint alleged that Dr. McDonagh's practice of chelation therapy constituted repeated negligence in violation of section 334.100.2. Section 334.100.2(5) allows for discipline for "any conduct or practice which is or might be harmful or dangerous to the mental or physical health of a patient or the public," and for "incompetency, gross negligence or repeated negligence" in professional duties. Section 334.100.2(5) defines "repeated negligence" as "the failure, on more than one occasion, to use that degree of skill and learning ordinarily used under the same or similar circumstances by the member of the applicant's or licensee's profession." This definition establishes the legal standard of care that must be applied in determining the board's claims of repeated negligence.
So is this off-label use of chelation therapy negligence? The real questionthe answer to which is fatal to the board's positionis whether acts of negligence, as defined by this statute, can be cause for discipline if there is no showing that the physician's conduct "is or might be harmful or dangerous." If there is no harm or danger, there is no cause for discipline under this section. Section 334.100.2(5) is a catchall provision; read in the context of the entire statute, it does not make negligent acts actionable unless there is harm or danger.[5] This subdivision cannot be read to make acts subject to discipline where there is no prospect of harm. If it were so read, the reading would make superfluous other provisions of the statute, such as 334.100.2(4)(f) as to treatments deemed by rule to have no medical value. There are provisions in section 334.100, including 334.100.2(4)(f), for disciplining medical quackeryeven where it causes no harm. But section 334.100.2(5), under which the board complains of Dr. McDonagh's practice, is not one of those sections.
Under section 334.100.2(5), no harm, no foul.
Physicians are afforded considerable leeway in the use of professional judgment to decide on appropriate treatments, especially when applying the negligence standard. For instance, Haase v. Garfinkel, 418 S.W.2d 108, 114 (Mo.1967), a medical negligence case, holds that "as long as there is room for an honest difference of opinion among competent physicians, a physician who uses his own best judgment cannot be convicted of negligence, even though it may afterward develop that he was mistaken." "Negligence" does not seem an appropriate concept where the physician has studied the problem and has made a treatment recommendation, even though that is not the prevailing view of the majority of the profession. The lack of general acceptance of a treatment does not *165 necessarily constitute a breach of the standard of care. The use of negligence in licensing situations, in the absence of harm or danger, is particularly inappropriate.
One could argue that because chelation therapy is not accepted by mainstream medicine and is an off-label practice not approved by the FDA, it is therefore harmful and dangerous. If that were the board's position, the licensing statute would thwart advances in medical science. A dramatic example is the treatment of stomach ulcers, which were long thought to be caused by stress. In 1982, two Australians found the bacterium helicobacter pylori in the stomach linings of ulcer victims. Because helicobacter pylori is a bacterium, some physiciansa minority to be surebegan prescribing antibiotics to treat stomach ulcers as an infectious disease. The National Institutes of Health did not recognize antibiotic therapy until 1994; the FDA approved the first antibiotic for use in treating stomach ulcers in 1996; and the Centers for Disease Control began publicizing the treatment in 1997. Today's physicians accept as fact that most stomach ulcers are primarily caused by helicobacter pylori bacteria infection and not by stress.[6] But, by the chronology of this discovery, if a physician in the late 1980s or early 1990s had treated ulcers with antibiotics, that treatment would have been "negligent" as the board in this case interprets that term because inappropriate use of antibiotics can be dangerous.
I do not mean to suggest that chelation therapy for vascular disease is of the same order as the use of antibiotics for treating stomach ulcers. In fact, I doubt it. But my point is that medicine is not readily regulated by a standard cookbook or set of rules. The board's position in publishing its 2001 rule on chelation therapy seems to recognize this point better than its position in this disciplinary action. If chelation therapy for vascular disease were dangerous, the board's rule that allows its use would be unconscionable.
In Dr. McDonagh's practice, all of his patients signed a consent to medical treatment and agreement that discusses the positive and negative aspects of chelation therapy and possible side effects. The patients are told that the therapy is not approved by the FDA, AMA or others. The patients consented nonetheless. Some of Dr. McDonagh's patients chose chelation therapy after exhausting more traditional medical treatments. Some may have benefited, perhaps because Dr. McDonagh accompanied the chelation treatment with recommendations for diet and exercise that are well known to be helpful for preventing and resolving some vascular disease. The record shows no harm to any patient.
In the absence of harm, or the probability of harm, can the repeated negligence standard of the licensing statute legitimately be used to enforce the board's opinion of what is conventional and, therefore, acceptable medicine?
The board conceded that there was no evidence of harm from chelation therapy. In the 35 years that he has used chelation therapy, Dr. McDonagh reports that the therapy has not resulted in infection, injury, or death for any of his patients. The commission repeatedly found that chelation therapy "harms no one" and provides "benefit to many patients."[7]
*166 Medicine is an art, as well as a science, as its practitioners are taught. It is also a dynamic field, where beliefs about what is conventional therapy can change over time. What is effective treatment is often a combination, not just of art and science, but of belief. The patient may get better if the patient is convinced of the usefulness of the therapy. The commission concluded that some of Dr. McDonagh's patients got better. Even if it is hard to believe these patients got better because of chelation therapy, the fact that some of Dr. McDonagh's patients got better is hardly cause for discipline. On this record, the absence of harm from chelation therapy, as I read the statute, negates the board's claim of repeated negligence.
Nor can it be said that the board or the commission believes that Dr. McDonagh's practice constitutes a danger to the public. The board has the power to move quickly to end practices that it considers dangerous. Section 334.102. The board sought no such immediate action.
This disciplinary action has, if anything, been conducted in slow motion. The healing arts board in 1989 apparently studied chelation therapy and issued a public statement that it chose "to take no action concerning chelation therapy" and would consider cases as they arose. Its first complaint against Dr. McDonagh was filed in 1994 but later dismissed without prejudice. The current complaint, in 13 counts, covers practices going back to 1978 and was filed in 1996. As noted, the current case was tried before the commission in 1997, but the commission's decision was not issued until 2000. There has been a noticeable lack of urgency by all concerned.
If this matter comes before the commission on remand, the commission is to review the evidence on the basis of the evidentiary principles in section 490.065. In my view, the commission should reach the same conclusion as before. In any event, to the extent that Dr. McDonagh's practice though it pre-dated the board's 2001 regulation conformed to the board's regulation on chelation, the board ought to be bound by its own standard. Dr. McDonagh has not yet raised the issue of whether the board should be bound by its own standard as expressed in its 2001 rule. But he will have the opportunity to do so on remand.
This case needs to be over. The board should end the case itself rather than suffer the indignity of further adverse commission and judicial rulings, to say nothing of the waste of public resources that such proceedings will entail.

Keyser, 81 S.W.3d 164, 169 (Mo.App. W.D. 2002) (citing section 490.065.3 as the standard for the admissibility of expert testimony without reference to either Frye or Daubert); Long v. Mo. Delta Med.

Yeargin, 11 S.W.3d 604, 619 (Mo.App. E.D.1999) (noting that "[t]he Missouri Supreme Court continues to apply the Frye test to the admissibility of expert testimony in criminal cases and in civil cases," and finding that "the trial court abused its discretion in admitting [the expert's] testimony because the court did not find that he based it on scientific principles generally accepted in the relevant scientific community or within the boundaries of Section 490.065"); Whitman's Candies, Inc. v. Pet, Inc., 974 S.W.2d 519, 528 (Mo. App. W.D.1998) ("[b]ecause the expert testimony at issue in the case at bar satisfies the requirements of both Frye and Daubert, this court need not determine whether [section] 490.065 supersedes the Frye test in Missouri" (emphasis in original)).
[10]  Indeed, although Missouri's Constitution leaves it to this Court to develop rules of procedure, it specifically prohibits the Supreme Court from creating rules of evidence. Mo. Const. art. V, sec. 5. See State v. Williams, 729 S.W.2d 197, 201 (Mo. banc 1987) ("[T]he legislature has plenary power to prescribe or alter the rules of evidence....").
[11]  See, e.g., secs. 536.070(6) ("Agencies shall take official notice of all matters of which the courts take judicial notice."); 536.070(8) ("The rules of privilege shall be effective to the same extent that they are now or may hereafter be in civil actions." (emphasis added)); 536.070(9) (As to "[c]opies of writings, documents and records," "the agency may, nevertheless, if it believes the interests of justice so require, sustain any objection to such evidence which would be sustained were the proffered evidence offered in a civil action in the circuit court. ..." (emphasis added)); 536.073.1 ("[A]ny party may take and use depositions in the same manner, upon and under the same conditions, and upon the same notice, as is or may hereafter be provided for with respect to the taking and using of depositions in civil actions in the circuit court. ..." (emphasis added)).
[12]  The effect of the addition of the phrase "in any civil action" is discussed supra. In 2000, language was added to the end of FRE 702 setting out in greater detail how the trial court, in its role as gatekeeper, should review the expert's testimony, stating that the court should find the testimony admissible "if (1) the testimony is based upon sufficient facts or data, (2) the testimony is the product of reliable principles and methods, and (3) the witness has applied the principles and methods reliably to the facts of the case."
[13]  Cf. Yantzi v. Norton, 927 S.W.2d 427 (Mo. App. W.D.1996) (negligence of professional engineer engaging in foundation repair was to be judged by standards of those with expertise in foundation repair, not merely by those who are professional engineers).
[14]  Dr. McDonagh objects that the Board has not preserved its objections to admission of his experts' testimony under section 490.065, and instead merely argued the testimony was inadmissible under Frye or Daubert. But, because the parties and AHC used the term "Daubert" to refer generally to any non-Frye approach to expert testimony, this Court finds it appropriate to reach the merits of the Board's arguments in this regard.
[15]  The Court notes that the term "repeated negligence" was not added to the statute until 1987. Therefore, although much of the conduct discussed at the hearing and that forms the basis of the Board's action occurred prior to 1987, the "repeated negligence" aspect of the Board's assertions of misconduct against Dr. McDonagh can be based only on his conduct after that provision was added to the statute.
[16]  Dr. McDonagh argues that expert testimony on the standard of care was not necessary. This Court disagrees. Because this case deals with complex issues as to the appropriate medical care for patients with vascular disease, a matter not within lay competence, expert testimony was necessary to determine what standard of care was required of Dr. McDonagh and whether he met that standard of care. See, e.g., Swope v. Printz, 468 S.W.2d 34, 40 (Mo.1971) (in medical malpractice cases, experts must incorporate the legal standard of care into their testimony to show that it is not "based upon [the expert's] own undisclosed subjective conception of acceptable medical standards" rather than the required, objective legal standard of care); Ladish v. Gordon, 879 S.W.2d 623, 634-35 (Mo.App. W.D.1994) ("[i]t is not necessary that the legal standard be recited in ritualistic fashion, but generally it must appear somewhere in the context of the expert's testimony that the proper objective legal standard is the standard being employed by this expert"); Dine v. Williams, 830 S.W.2d 453, 456 (Mo.App. W.D.1992) (accord).
[17]  See, e.g., Silberstein v. Berwald, 460 S.W.2d 707, 709 (Mo.1970) ("The defendant was required to use and exercise that degree of skill and proficiency which is commonly experienced by the ordinary, skillful, careful and prudent physician and surgeon engaged in the practice of medicine"); Hart v. Steele, 416 S.W.2d 927, 931 (Mo.1967) (accord); Williams v. Chamberlain, 316 S.W.2d 505, 510 (Mo.1958) (accord).
[18]  In 2002, the Missouri General Assembly passed section 334.097, governing the maintenance of medical records. Sec. 334.097, RSMo Supp.2002.
[19]  Because of the resolution of the other issues addressed above, it is unnecessary for the Court to address Dr. McDonagh's argument that adoption of the Board's position on chelation therapy would constitute an unreasonable restraint on his right and the right of his patients to choose alternative medicine treatment modalities.
[1]  All statutory references are to RSMo 2000.
[2]  Section 490.065, in its entirety, provides:

1. In any civil action, if scientific, technical or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education may testify thereto in the form of an opinion or otherwise.
2. Testimony by such an expert witness in the form of an opinion or inference otherwise admissible is not objectionable because it embraces an ultimate issue to be decided by the trier of fact.
3. The facts or data in a particular case upon which an expert bases an opinion or inference may be those perceived by or made known to him at or before the hearing and must be of a type reasonably relied upon by experts in the field in forming opinions or inferences upon the subject and must be otherwise reasonably reliable.
4. If a reasonable foundation is laid, an expert may testify in terms of opinion or inference and give the reasons therefor without the use of hypothetical questions, unless the court believes the use of a hypothetical question will make the expert's opinion more understandable or of greater assistance to the jury due to the particular facts of the case.
[3]  Section 334.100.2 provides, in pertinent part:

The board may cause a complaint to be filed with the administrative hearing commission as provided by chapter 621, RSMo, against any holder of any certificate of registration or authority, permit or license required by this chapter or any person who has failed to renew or has surrendered the person's certificate of registration or authority, permit or license for any one or any combination of the following causes: (5) Any conduct or practice which is or might be harmful or dangerous to the mental or physical health of a patient or the public; or incompetency, gross negligence or repeated negligence in the performance of the function or duties of any profession licensed or regulated by this chapter. For the purposes of this subdivision, "repeated negligence" means the failure, on more than one occasion, to use that degree of skill and learning ordinarily used under the same or similar circumstances by the member of the applicant's or licensee's profession[.]
[4]  The board's complaint also relates to record keeping and use of diagnostic tests, but these charges seem to be premised on the board's objection to Dr. McDonagh's practice of chelation therapy for treating vascular disease. There may be a question whether Dr. McDonagh ordered unnecessary tests, without reference to chelation therapy, or whether the tests Dr. McDonagh ordered were deemed by the board to be unnecessary because they were part of chelation therapy that the board believes is useless.
[5]  For those who like the comfort of case citations, Missouri's common law of negligence is consistent with this reading of section 334.100.2. In common law actions for negligence, the concept of negligence is inextricably linked to the causation of harm. All actions for negligence require a plaintiff to establish that "the defendant had a duty to protect her from injury, that the defendant breached that duty, and that the defendant's failure directly and proximately caused her injury." Robinson v. Health Midwest Development Group, 58 S.W.3d 519, 521 (Mo. banc 2001). For a medical negligence action, a plaintiff must prove that the defendant failed to use that degree of skill and learning ordinarily used under the same or similar circumstances by members of defendant's profession and that the negligent act or acts caused plaintiff's injury. Washington by Washington v. Barnes Hosp., 897 S.W.2d 611, 615 (Mo. banc 1995).
