MAASSEN, Justice.
I. INTRODUCTION
The state professional licensing division brought an accusation of professional misconduct against a doctor, alleging that he acted incompetently when he prescribed phentermine and thyroid hormone for one of his patients. The division sought disciplinary sanctions against the doctor. Following a hearing, an administrative law judge issued a proposed decision concluding that the division had failed to show that the doctors conduct fell below the standard of care in his field of practice and that no disciplinary sanctions were warranted. But the Medical Board instead adopted as its decision the proposal for action submitted by the division and revoked the doctors medical license.
On appeal to the superior court, the case was remanded to the Board for consideration of the doctors own late-filed proposal for action. The Board reaffirmed its decision to revoke the doctors medical license, and the superior court affirmed that decision.
The doctor appeals to this court. Because the Medical Boards decision to revoke the doctors medical license is not supported by substantial evidence, we reverse the superior courts affirmance of that decision.
II. FACTS AND PROCEEDINGS
David Odom is a bariatric physician who has been licensed to practice in Alaska since 1974. His Fairbanks practice focused on anti-aging, weight loss treatment, and natural hormone replacement therapy. He is certified by the American Board of Medical Specialties in anesthesiology and by the American Academy of Anti-Aging and Regenerative Medicine, and he has been admitted to practice in six states besides Alaska. The disciplinary action in this case is his first.
A. Dr. Odoms Treatment Of S.Q.
In April 2007 Dr. Odom began seeing S.Q. for weight loss treatment and hormone evaluation. He noted at her first appointment that she had an irregularly irregular heartbeat; she reported that in 2002 she had been diagnosed with peripartum cardiomyopathy, though it was currently asymptomatic. Cardiomyopathy is a disease of the heart muscle that can lead to sudden cardiac arrest and death; peripartum cardiomyopathy by definition begins during the final month of pregnancy or within a few months after giving birth.
Dr. Odom recorded his initial impressions: thyroid deficiency, hormone imbalance, cardiomyopathy, and obesity. S.Q. signed an informed consent form for weight loss treatment and another for hormone supplement therapy. Dr. Odom scheduled weekly appointments for S.Q. from April through June 2007, continuing monthly into September, so he could monitor her progress.
The obesity treatment plan included a prescription for phentermine, a central nervous system stimulant that suppresses appetite. Dr. Odom also prescribed a natural thyroid hormone drug-Armour Thyroid -for hypothyroidism. He instructed S.Q. to start the thyroid drug at a dose of 120 milligrams daily, increasing to 180 milligrams after two weeks and 240 milligrams after four weeks; after that she could adjust the dosage herself based on her symptoms.
At S.Q.s September 14, 2007 visit-her last to Dr. Odoms clinic-she was found to have lost 33 pounds, dropping below the weight considered clinically obese. She reported, however, that she had experienced jitteriness while taking a 240 milligram dose of Armour Thyroid, so Dr. Odom reduced the dose to 180 milligrams a day. S.Q. appears to have stopped taking both medications soon afterward; she last filled her phentermine and Armour Thyroid prescriptions on September 10, when she received a thirty day supply of each, and some pills were never used.
A month later S.Q. visited her cardiologist, who reported that she has had a remarkable year and with careful adjustment of her diet, successfully lost 30 pounds. In early 2008, according to her husband, she looked better and happier than she had in a long time. But on March 6, 2008, about six months after she had stopped seeing Dr. Odom, she suffered cardiac failure and died.
B. The Licensing Divisions Investigation
In 2009 S.Q.s husband filed a complaint with the State of Alaska Division of Corporations, Business, and Professional Licensing, suggesting a link between Dr. Odoms treatment of S.Q. and her death. The Division launched an investigation and sent S.Q.s medical records to Dr. Patrick Nolan for review. Dr. Nolan, an endocrinologist, concluded that it was inappropriate for Dr. Odom to have prescribed phentermine given S.Q.s cardiomyopathy ; that Dr. Odom had prescribed too much thyroid hormone; and that Dr. Odom had inappropriately prescribed thyroid hormone for weight loss. Dr. Nolan also opined that the excess thyroid [hormone] and phentermine could have contributed to [S.Q.s] death.
Dr. Odom challenged these conclusions, asserting that Dr. Nolan, as an endocrinologist, had a starkly different view of weight loss and natural hormone replacement therapy than doctors who, like Dr. Odom, practice anti-aging and bariatric medicine. Dr. Nolan responded by declaring Dr. Odoms practice dangerous and clearly ... a threat to the publics well being, though his explanation was terse; he said in his supplemental report, I simply refuse to argue with [Dr. Odoms approach to treatment] as clearly the evidence is in favor of modern endocrinology and against Dr. Odom.
In April 2012 the Division filed an accusation alleging that Dr. Odom had provided substandard care by failing to conduct an adequate examination of S.Q., prescribing phentermine to a patient with an established diagnosis of cardiomyopathy, and prescribing excess thyroid hormone in combination with phenterminefor weight loss. The Division did not contend that Dr. Odoms treatment caused S.Q.s death; in this appeal the Division, through its attorney at oral argument, agreed absolutely that there was no causal connection.
C. The Administrative Proceedings
An administrative law judge (ALJ) held an evidentiary hearing on the Divisions accusation over four days in October and November 2012. The Division presented the testimony of S.Q.s husband, her mother, the Division investigator, and Dr. Nolan, who testified as an expert. Dr. Odom testified on his own behalf and also presented the expert testimony of Dr. David Bryman, a bariatric physician, and Dr. Neal Rouzier, an emergency medicine, family practice, and anti-aging physician.
The ALJ issued a proposed decision in April 2014. He concluded that the Division had failed to prove that Dr. Odoms examination was below the standard of care; had failed to prove that to prescribe phentermine to S.Q. was below the standard of care; and had failed to prove that Dr. Odom prescribed thyroid hormone as a weight loss treatment, or that the dosages he prescribed were excessive and fell below the standard of care. The ALJ therefore concluded that no disciplinary sanction was warranted.
D. The Parties Proposals For Action And The Medical Boards Decision
As permitted by AS 44.64.060(e), the Division submitted a proposal for action in May 2014 that disputed the ALJs findings and recommended that the Medical Board impose disciplinary sanctions. The Division argued that Dr. Odoms practice fell below the standard of care when he prescribed phentermine to a patient with cardiomyopathy and when he prescribed four times the recommended dosage of thyroid hormone to S.Q. for supposed hypothyroidism, when her thyroid levels were in fact normal. The Division asserted that its proposed conclusions, though contrary to those of the ALJ, could be reached based on the evidence contained in the [ALJs] proposed decision (including the product literature), and the Boards own medical expertise.
The Medical Board was scheduled to meet to decide Dr. Odoms case in June 2014, and it received the ALJs proposed decision and the Divisions proposal for action beforehand. A problem with the mail prevented Dr. Odom from filing his own proposal for action, and though he tardily filed an opposition to the Divisions proposal, the Medical Board did not review it.
At its June meeting the Medical Board discussed Dr. Odoms case in executive session; the members then voted unanimously, on the record, to reject the proposed decision by the ALJ and, instead, adopt the Divisions Proposal for Action as its final agency decision. As a sanction, the Medical Board ordered the revocation of Dr. David Odoms Alaska medical license.
E. Dr. Odoms Appeal To The Superior Court And Remand
Dr. Odom appealed the Medical Boards decision to the superior court. The court held that substantial evidence supported the Boards factual and disciplinary findings, but it found a violation of Dr. Odoms due process rights in the Boards failure to consider his late-filed opposition to the Divisions proposal for action; the superior court therefore vacated the Boards decision and remanded the matter to the Board for reconsideration.
At a special meeting, the Medical Board decided not to re-open the evidence in this case as is its prerogative, and it reaffirmed its decision to revoke Dr. Odoms license. In November 2015 the superior court issued an order affirming the Boards decision.
Dr. Odom appealed to this court.
III. STANDARDS OF REVIEW
When a superior court acts as an intermediate court of appeals reviewing an administrative or agency decision, we independently review the merits of the administrative decision, giving no deference to the superior courts decision. We review the agencys factual findings to determine whether they are supported by substantial evidence. Substantial evidence is such relevant evidence as a reasonable mind might accept as adequate to support a conclusion. The substantial evidence test is highly deferential, but we still review the entire record to ensure that the evidence detracting from the agencys decision is not dramatically disproportionate to the evidence supporting it such that we cannot conscientiously find the evidence supporting the decision to be substantial. The substantial evidence standard reflects the prudence of deferring to a state professional boards special competence in recognizing violations of professional standards. But we will not uphold the imposition of reputationally and economically damaging professional sanctions based on evidence that would not permit a reasonable mind to reach the conclusion in question.
We review questions of law, including the appropriate standard of proof, using our independent judgment. We review the agencys selection of a particular disciplinary sanction for abuse of discretion.
IV. DISCUSSION
Alaska Statute 08.64.326(a)(8)(A) authorizes the Medical Board to sanction a doctor if the Board finds after a hearing that the doctor has demonstrated professional incompetence. Professional incompetence is defined by regulation to mean lacking sufficient knowledge, skills, or professional judgment in that field of practice in which the physician ... concerned engages, to a degree likely to endanger the health of his or her patients. Sanctions for professional incompetence may range from a letter of reprimand or required education to revocation of a medical license. The Administrative Procedure Act provides that if an accusation has been filed under AS 44.62.360 (to determine whether a license should be revoked, suspended, limited, or conditioned), the accusing authority has the burden of proof by a preponderance of the evidence unless applicable law requires otherwise. We assume for purposes of this discussion that the preponderance of the evidence standard applies.
Dr. Odom challenges the Medical Boards decision to revoke his license as lacking substantial evidence in support of it. His argument targets the Boards two underlying findings: (1) that prescribing phentermine to S.Q. was below the standard of care because of her cardiomyopathy, and (2) that prescribing thyroid hormone to S.Q. was below the standard of care because the dosage prescribed was excessive and it should not have been given in combination with phentermine. We agree that the Boards decision lacks sufficient support in the evidence.
A. The Medical Boards Decision Does Not Support License Revocation.
We begin by explaining why the Medical Boards decisional document does not support its conclusion regardless of how we view the evidence of Dr. Odoms treatment of S.Q. We note parenthetically that the Medical Boards adoption of the Divisions proposal as its final decision was clearly not what the Division had anticipated; the Division had proposed that the Board amend the ALJs decision in some particulars, and the only sanctions it discussed were a license suspension or alternatively a fine, reprimand, probation, education, and permanent restriction on respondents practice, including a prohibition against prescribing phentermine and thyroid hormone to patients.
The Boards procedure was also irregular. The law requires that the Board support the revocation of a medical license with a written decision and a brief and concise statement of the grounds and reasons for the action. The decisional document of any administrative body, done carefully and in good faith, serves several salutary purposes, such as facilitat[ing] judicial review by demonstrating those factors which were considered and tend[ing] to ensure careful and reasoned administrative deliberation. An ALJs proposed decision is usually in a form that will serve these purposes, if it is adopted by the Board. And AS 44.64.060(e) sets out other options if the Board declines to adopt the ALJs proposed decision, including returning the case to the ALJ for further proceedings, changing the ALJs recommended disposition, and rejecting, modifying, or amending the ALJs factual findings (by specifying the affected finding and identifying the testimony and other evidence relied on by the agency for the rejection, modification, or amendment of the finding). The Medical Boards nonadoption options do not expressly contemplate accepting one partys proposal for action as the Boards decision, as the Board did here; that may work sometimes, but on the other hand the proposal for action may well be, as it was here, a piece of party advocacy rather than an ostensibly impartial decisional document that clearly sets out the Boards rationale and helps facilitate judicial review.
The document that became the Boards final decision in this matter thus contains no findings of its own but asserts that its conclusion can be reached based on the evidence contained in the [ALJs] proposed decision (including the product literature), and the Boards own medical expertise. But the document also suggests specific amendments to the ALJs decision and invites the Board to enlist the assistance of the attorney generals office in making revisions. While a member of the public who has both the Divisions proposal for action and the ALJs recommended decision in hand could thus-perhaps-stitch together a single decisional document with a coherent narrative, it is not at all clear that the documents factual findings would lead to its conclusion. And the Boards decision on remand, after considering Dr. Odoms late-filed proposal for action, adds no explanation other than the conclusory statement that its earlier decision, as embodied in the Divisions proposal for action, was supported by substantial evidence.
Most importantly, the document that became the Boards final decision expressly states that [i]mposing a suspension on Dr. Odoms license would be consistent with prior Board decisions involving inappropriate prescribing by physicians (emphasis added) and supports this statement with a discussion of relevant legal authorities. The Board, however, revoked Dr. Odoms license instead, based not on any written explanation but presumably on its discussion in executive session. By statute, the Medical Board must be consistent in the application of disciplinary sanctions, and [a] significant departure from earlier decisions of the board involving similar situations must be explained in findings of fact or orders made by the board. In professional incompetence cases, the Medical Board has generally directed its efforts to imposing appropriate limits on [the doctors] practice or to seeking to upgrade [the doctors] performance. This approach is reflected in the Divisions proposal in this case that the Board, to be consistent with its precedent, impose a suspension or consider lighter sanctions as alternatives.
License revocations, in contrast, are more likely to follow revocations in other states or convictions for crimes such as fraud, felony drug offenses, or sex offenses. We have also affirmed a license revocation based on a pattern of inadequacy, but this case involves only Dr. Odoms treatment of S.Q.; the Division did not allege or pursue a claim that Dr. Odom acted incompetently in any cases besides this one. And given the Divisions further concession that Dr. Odoms treatment of S.Q. had no causal connection to her death, there is no reason apparent in the Boards decisional document why S.Q.s case alone would warrant a sanction that is inconsistent with the Boards precedent.
We conclude that the Boards final decision fails to comply with its statutory duty to be consistent in the application of disciplinary sanctions or explain the inconsistency, and it therefore does not support the sanction imposed.
B. The Medical Boards Conclusion That Dr. Odoms Prescription Of Phentermine To S.Q. Was Below The Standard Of Care In His Field Of Practice Is Not Supported By Substantial Evidence.
The Medical Boards decisional document is legally insufficient not only with regard to its choice of sanction, but also in its conclusion that Dr. Odom acted incompetently. One of the reasons the Board gave for adopting the Divisions position was that it was unprofessional, incompetent, and below the standard of care for Dr. Odom to prescribe phentermine to a patient with known cardiomyopathy. This conclusion relied primarily on the testimony of Dr. Nolan, bolstered by product literature and a reference book. But we conclude that this evidence is insufficient to support the Boards finding of incompetence.
Dr. Nolan, the Divisions only medical witness, testified that he was board certified in internal medicine and endocrinology. He testified that his practice usually involves patients who have diabetes or some kind of thyroid disease; many of his diabetic patients have weight problems, but he does not use any drug therapy specifically for weight loss. Indeed, when asked by the Division at the outset of its investigation whether he perform[ed] the type of practice which is in dispute in this matter, he answered No, explaining that he did not prescribe the medicines at issue. He testified at the hearing that he has not prescribed phentermine in many years because he found it to be ineffective in the long run and because its very controversial.
Dr. Nolan nonetheless did not review any recent studies of phentermine before forming his opinions in the case and, despite his role as an expert witness, admitted that he ha[d]nt researched it out that carefully. He testified that he had reviewed the package insert; the online entry for phentermine in the Physicians Desk Reference , which contains the same manufacturer-provided information as the package insert; and Lexicomps Drug Information Handbook , which he described as a more reliable sourcebook prepared by the American Pharmacists Association. He described the package insert as contraindicating the use of phentermine for patients with cardiac disease, and he testified that contraindications in package inserts are clear statements to physicians not to prescribe a drug under the given circumstances. He also testified that the Drug Information Handbook contains a severe warning against the use of stimulants ... in patients with ... cardiomyopathy. Dr. Nolan admitted, however, that the package insert [for a drug] may or may not be totally reliable and that a physician should not rely solely upon the Drug Information Handbook either. But he also testified that he had asked seven cardiologists whether they would consider using phentermine in a patient with known cardiomyopathy, and they all answered, Absolutely not. He concluded that Dr. Odom should not have prescribed phentermine to treat S.Q.s obesity because of her history of cardiomyopathy, and that doing so was below the standard of care.
The manufacturers literature for phentermine clearly states that the drug is contraindicated for patients with cardiovascular disease, though whether that includes S.Q.s asymptomatic peripartum cardiomyopathy is a debatable issue, one that the ALJ noted but did not decide. The Division argued for a broad interpretation of the contraindications and warnings as applying to all kinds of heart diseases and conditions, and the Board ostensibly adopted that interpretation. But we need not consider this issue ourselves; regardless of whether phentermines manufacturer intended cardiomyopathy to be among the listed contraindications, the evidence disproportionately supports a conclusion that the contraindications do not establish a relevant standard of care, and furthermore that Dr. Odoms prescription of phentermine to S.Q. was within the standard of care for physicians who practice in his field.
Dr. Bryman, one of Dr. Odoms expert witnesses, is a physician licensed in Alaska and several other states who practices primarily in bariatrics. He has served on the American Board of Bariatric Medicine and is active in the American Society of Bariatric Physicians. He testified that he is very familiar with phentermine ; he has prescribed it in his practice for over 20 years, has lectured on the drug, and has defended other physicians use of the drug. As the ALJ summarized Dr. Brymans testimony, phentermine is routinely prescribed for anorectic [appetite-suppressant] purposes by bariatric physicians nationwide.
Dr. Bryman also addressed phentermines contraindications. He strongly supported Dr. Odoms view that contraindications on drug labels generally are not binding on physicians and do not establish a standard of care, and that the product literature on phentermine in particular was outdated and misleading. While disputing that cardiomyopathy is a cardiovascular disease, he discussed several studies indicating that phentermine did not cause the adverse cardiovascular effects the product literature warns about. Both Dr. Bryman and Dr. Rouzier, Dr. Odoms other expert witness, testified that phentermines contraindications and warnings regarding its use with cardiac patients were based on 50-year-old research on amphetamines, a chemically related but fundamentally different compound with much different effects, and that the drugs literature had not been updated despite new studies showing that phentermine does not have any of those properties that ... amphetamines [have]. Dr. Bryman testified that the FDA had recently approved a new drug containing phentermine based on studies that showed no adverse cardiovascular effects at all. He testified that about 30% of his own patients had some form of heart disease and were referred to him by their cardiologists, and that he prescribed phentermine to patients with cardiomyopathy.
Dr. Bryman noted that S.Q.s medical records showed no increase in her heart rate or blood pressure while she was on phentermine, and that in fact, because of her obesity and cardiomyopathy, she was a perfect patient for the drug. He concluded with certainty that [Dr. Odom] practiced to the standard of care like a reasonable doctor would treat a patient and not allow her to continue her obesity and worsen her condition. So he intervened appropriately, in my opinion, and she got better. Dr. Rouzier, too, testified adamantly that the best treatment for S.Q.s obesity was weight loss and that phentermine was a safe and effective way to promote it.
The ALJ who presided over the evidentiary hearing noted that the Division did not call S.Q.s treating cardiologist, or any other cardiologist, as a witness, and it did not admit into evidence any studies of phentermine to support the allegations of the accusation. The ALJ contrasted the Divisions expert witness, Dr. Nolan, who has little clinical experience with phentermine, with Dr. Odoms expert witness, Dr. Bryman, who had substantial clinical experience with phentermine, including the use of phentermine for patients referred by cardiologists. The ALJ concluded that the Division has not shown by a preponderance of the evidence that it was below the standard of care to prescribe phentermine to S.Q. We agree with this conclusion. The evidence detracting from the Boards decision is dramatically disproportionate to the evidence in support of it, meaning that we cannot conscientiously say that the supporting evidence is substantial.
Finally, the Divisions proposal for action-the Boards final decision-cited an earlier Medical Board decision in support of the proposition that a doctors prescription contrary to manufacturer-provided contraindications can show a breach of the standard of care. In re Bartling dealt in part with a claim that a doctor had prescribed an opioid to a patient who was not opioid tolerant, contrary to FDA warnings listed on the products packaging. The Board concluded that the patient actually was opioid tolerant and therefore there was no violation of the standard of care. But the Board noted the testimony of two experts that the warning was a guide, and that in some cases it is medically appropriate to prescribe [the drug] to a patient who is not opioid tolerant despite the warnings. And the Board in Bartling did not have to address issues like those in this case about whether more recent research and clinical experience undermined the credibility of the product literature. Bartling does not support the Boards decision in this case.
C. The Medical Boards Conclusion That Dr. Odoms Prescription Of Thyroid Hormone Fell Below The Standard Of Care In His Field Of Practice Was Not Supported By Substantial Evidence.
The Medical Board also adopted as its final decision the Divisions argument that Dr. Odoms conduct was unprofessional, incompetent, and below the standard of care when he prescribed thyroid hormone to S.Q. The Board apparently accepted the ALJs relevant factual findings: that Dr. Odom prescribed Armour Thyroid in late June 2007 with a beginning dosage of 120 milligrams a day, increasing to 180 milligrams after two weeks and 240 milligrams after four weeks, and that he decreased it to 180 milligrams in September after S.Q. reported jitteriness on the 240-milligram dose. While the ALJ found no breach of the standard of care in this chronology, the Board reached two much different conclusions: (1) that Dr. Odom prescribed an excessive dosage of thyroid hormone, and (2) that it was inappropriate to prescribe thyroid hormone along with phentermine given the risks associated with using the two drugs in combination. Dr. Odom argues that these findings are not supported by substantial evidence, and again we agree with him.
The Medical Board adopted the Divisions argument that S.Q. received too much thyroid too soon because the product literature state[s] that for hypothyroidism, the usual starting dose [of Armour Thyroid] was 30mg, with increments of only 15mg every 2 to 3 weeks, whereas S.Q. started with 120 milligrams and reached 240 milligrams five weeks later. The Boards decision is supported by the testimony of Dr. Nolan, who did not prescribe Armour Thyroid in his own practice but opined that Dr. Odom prescribed too much of it, basing his opinion on what he read in the Drug Information Handbook and the manufacturers literature. Dr. Nolan testified that the Drug Information Handbook says the recommended adult dosage of Armour Thyroid is [f]ifteen to 30 milligrams initially.
But the Drug Information Handbook and the manufacturers literature both use the word recommended only in conjunction with pediatric dosages, which range from 15 milligrams to over 90 milligrams. The manufacturers literature does state that the usual starting dose is 15 to 30 milligrams, to be scaled up by 15 milligrams every few weeks. And the manufacturers literature and the Handbook agree that [m]ost patients require 60 to 120 mg/day. But neither the manufacturers literature nor the Handbook supports the Boards necessary extrapolation: that S.Q. was among most patients for whom the usual starting dose was the only medically appropriate one, and that prescribing dosages other than the usual ones was necessarily unsafe or below the standard of care.
Aside from the dosages listed in the Drug Information Handbook and the manufacturers literature, the only evidence of a proper dosage at the hearing came from Dr. Odom and his expert witness, Dr. Rouzier, who regularly teaches courses in hormone replacement for various medical academies including the American Academy of Family Physicians. Dr. Odom testified that the average adult dosage is 4 grains (240 milligrams) per day. Dr. Rouzier testified that the standard dosage is between 2 and 4 grains (120 to 240 milligrams) per day. Dr. Rouzier also testified that S.Q.s dosages-from 120 milligrams to 240 milligrams then back down to 180 milligrams per day-were very appropriate and within the range of whats standard and available ... for us to prescribe. According to Dr. Rouzier, S.Q.s dosage even at its highest was a standard, middle-of-the-range, middle-run dose. Not too high, not too low. He also testified that the drug manufacturer makes 4 grain, 5 grain, and 6 grain tablets; the manufacturers literature and the Drug Information Handbook confirm that 4 grain and 5 grain tablets (240 and 300 milligrams) are available, which runs counter to the Medical Boards conclusion that S.Q.s lower dosages were necessarily excessive.
Dr. Rouziers and Dr. Odoms estimates of standard dosages are indeed higher than what the Drug Information Handbook lists as usual maintenance doses ([u]sually 60-120 mg/day), but every patient cannot be the usual patient. The manufacturers literature adds, The dosage of thyroid hormones ... must in every case be individualized according to patient response and laboratory findings. Dr. Rouzier testified accordingly that some patients achieve the best results from taking significantly higher doses of thyroid hormone than those prescribed to S.Q. According to Dr. Rouzier, S.Q.s dosages were within the safe range.
The Division presented some evidence about the risks of excessive thyroid hormone. The manufacturers literature notes that [e]xcessive doses of thyroid result in a hypermetabolic state, essentially inducing hyperthyroidism . Dr. Nolan testified that too much thyroid hormone can eventually lead to atrial fibrillation and bone loss, and Dr. Rouzier testified that extremely high doses could lead to palpitations [and] tachycardia. But Dr. Rouzier also testified that if a patient starts seeing side effects like jitteriness (as S.Q. did), the dosage can simply be scaled back, and the drugs effect will dissipate in less than 24 hours. This is consistent with the manufacturers literature, which suggests that overdoses of Armour Thyroid be treated by simply reducing or temporarily discontinuing the usual dosage. And the Division failed to establish how much thyroid hormone is too much. Again, we cannot conscientiously say that the Medical Boards finding that Dr. Odom prescribed an excessive dosage of Armour Thyroid is supported by substantial evidence.
Similarly unsupported is the Boards conclusion that S.Q. received too much thyroid hormone too soon. There was little evidence on this issue presented at the hearing. In Dr. Nolans rebuttal testimony he referred to the dosage as being excessive to start with, apparently by referencing only the usual dosages entry in the Drug Information Handbook . But again, there is no basis in the record for inferring that a physician breaches the standard of care unless he treats every patient as the usual patient. Given the strong contrary testimony of Dr. Odom and Dr. Rouzier, we conclude that substantial evidence does not support the Boards finding that a starting dosage differing from those listed in the Drug Information Handbook indicated a breach of the standard of care.
The Medical Board also accepted the Divisions argument that it was unsafe for Dr. Odom to combine thyroid hormone and phentermine when prescribing for S.Q. In support of this argument the Division cited only the product literature for Armour Thyroid, which reads in part, Larger doses may produce serious or even life-threatening manifestations of toxicity, particularly when given in association with sympathomimetic amines [e.g., phentermine ] such as those used for their anorectic effects. But this warning is explicitly directed toward the drugs use [i]n euthyroid patients, meaning patients with normal thyroid gland function. Whether S.Q. had normal thyroid gland function was another disputed issue. Dr. Nolan testified that she did, based on laboratory tests showing thyroid levels within the normal range. The ALJs recommended decision, however, described the symptoms that led Dr. Odom to his clinical diagnosis of hypothyroidism and noted the dispute between physicians who rely on lab tests to determine normal thyroid function and those who subscribe to an alternative view, accepted by many clinicians in their field of practice, to the effect that normal laboratory findings simply reflect the thyroid hormone levels found in the population generally, rather than the levels that will result in optimal functioning. But this dispute was ultimately irrelevant, because, as the ALJ concluded, the Divisions accusation did not allege that Dr. Odom misdiagnosed hypothyroidism, but rather that, assuming S.Q. had hypothyroidism, he prescribed too much thyroid hormone to treat it.
Besides the manufacturers literature, Dr. Nolan also testified that excess thyroid hormone and [p]hentermine is not a good combination; [t]he risks of using phentermine with high doses of Armour Thyroid in persons with established cardiomyopathy is not a good idea. Its just too risky. But Dr. Nolan did not explain why the combination was unsafe, nor did his testimony shed light on whether he believes phentermine combined with lower doses of thyroid hormone would be within the standard of care.
Finally, both Dr. Rouzier and Dr. Bryman, who were able to testify from their own direct experience treating patients in Dr. Odoms fields of practice, concluded that Dr. Odom was acting within the standard of care in prescribing phentermine and thyroid hormone to S.Q. Dr. Rouzier testified, The only thing that helps [obese, hypothyroid ] patients is weight loss. Get the fat off.... How do you do that? Phentermine and thyroid.
Having reviewed the record, we cannot conscientiously find the evidence supporting the [Boards] decision to be substantial. The record does not support the Medical Boards conclusion that Dr. Odom prescribed excess thyroid hormone to S.Q., or that it was unsafe or incompetent to prescribe phentermine in combination with thyroid hormone.
D. The Medical Boards Decision Must Be Reversed.
We conclude that the Division failed to prove that Dr. Odom lack[s] sufficient knowledge, skills, or professional judgment in that field of practice in which [he] engages. We note that the legislature has expressly warned against bas[ing] a finding of professional incompetence solely on the basis that a licensees practice is unconventional or experimental in the absence of demonstrable physical harm to a patient. The Division disclaims any intent to violate this statutory directive, but it is hard to overlook the fact that this case, involving no demonstrable physical harm to a patient, resulted in the Board excessively sanctioning the respondent for an approach that the evidence showed was commonly taken by physicians in his field of practice. We conclude that the Medical Board lacked sufficient evidence to support its findings and that the Medical Board abused its discretion by revoking Dr. Odoms medical license.
V. CONCLUSION
For the foregoing reasons, we REVERSE the superior courts decision affirming the decision of the Medical Board to revoke Dr. Odoms medical license.

According to the administrative law judge, [t]estimony at the hearing established that the medication prescribed by Dr. Odom would have long since been eliminated from [S.Q.s] system, and she had been treated by her cardiologist on several occasions since her last visit to Dr. Odom some six months before her death. The Board did not modify this finding, and the Division does not challenge it.

[A] court may [not] displace the Boards choice between two fairly conflicting views, even though the court would justifiably have made a different choice had the matter been before it de novo.

Our opinion, when first published, applied a clear and convincing evidence standard, citing the due process analysis of Nguyen v. State, Dept of Health Med. Quality Assurance Commn , 144 Wash.2d 516, 29 P.3d 689, 696 (2001).

Dr. Nolan described internal medicine as including a whole list of ... different subspecialities: pulmonary disease, cardiology, gastrointestinal, rheumatology, dermatology, endocrinology, and he defined endocrinology as the study of endocrines, ... which are the ductless glands in your body: the pituitary, the thyroid, the adrenal, outlet cells in the pancreas, parathyroid, things like that.See also Endocrinology , Stedmans Medical Dictionary (28th ed. 2006).
Dr. Nolan testified that cardiomyopathy is a form of cardiovascular disease. Both of Dr. Odoms experts testified that S.Q.s condition, peripartum cardiomyopathy, is a disease of the heart muscle rather than the vascular system, is thus not a cardiovascular disease, and is not among phentermines listed contraindications.
The ALJ cited several federal cases in support of this proposition. See Planned Parenthood Sw. Ohio Region v. DeWine , 696 F.3d 490, 496 n.4 (6th Cir. 2012) (The FDA regulates the marketing and distribution of drugs by manufacturers, not the practices of physicians in treating patients.); Weaver v. Reagen , 886 F.2d 194, 198 (8th Cir. 1989) (FDA approved indications were not intended to limit or interfere with the practice of medicine nor to preclude physicians from using their best judgment in the interest of the patient.); id.

The Boards decision also cites cases from other jurisdictions in which doctors were found to have inappropriately prescribed phentermine to patients with cardiac problems. Zak v. Riffel , 34 Kan.App.2d 93, 115 P.3d 165, 170 (2005) (expert testified that phentermine should not have been prescribed to a patient with left ventricular dysfunction ); Fletcher v. Pa. Prop. & Cas. Ins. Guar. Assn , 27 A.3d 299, 302 (Pa. Cmmw. 2011) (malpractice damages awarded, in part, because phentermine was inappropriately prescribed to a patient with coronary artery disease ); Ancier v. State, Dept of Health , 140 Wash.App. 564, 166 P.3d 829, 834 (2007) (doctor inappropriately prescribed 180,000 medications, including phentermine, over the internet; expert testified that phentermine is dangerous for patients with cardiovascular disease ). None of these cases address S.Q.s particular malady, asymptomatic peripartum cardiomyopathy.
Dr. Rouzier explained that normal simply refers to an average of the population rather than what might be best for a particular patient. And Dr. Bryman explained that normal can differ between patients at a healthy weight and those who are obese, just as normal will differ between pediatric and geriatric patients.
Hyperthyroidism is [a]n abnormality of the thyroid gland in which secretion of thyroid hormone is usually increased and no longer under regulatory control of hypothalamic-pituitary centers. Hyperthyroidism , Stedmans Medical Dictionary (28th ed. 2006).
Dr. Nolan testified that in his experience, most people [taking] around 3 or 4 grains [180 to 240 milligrams] of dessicated thyroid per day will have perturbation of thyroid function, which is not desirable. But Dr. Nolan also admitted that he never prescribes Armour Thyroid, and that he believes the use of Armour Thyroid to be substandard and unconventional. He testified that practitioners in the field of endocrinology have sought to remove Armour Thyroid from the market.
See Euthyroidism , Stedmans Medical Dictionary (28th ed. 2006).
The Boards decision does not appear to rely on the Drug Information Handbook for its findings about the use of thyroid hormone and phentermine in combination. The Handbook does not suggest that combining the two drugs is unsafe. The Handbook s section on phentermine advises prescribing physicians to [a]void concomitant use of phentermine with several drugs but not including thyroid hormone, and the Handbook does not include thyroid hormone in the list of drugs for which phentermine may increase or decrease the effect or toxicity. Nor does the Handbook s section on thyroid hormone warn against combining it with phentermine.

See 12 AAC 40.970 (defining professional incompetence).
The Division argues on appeal that Dr. Odoms field of practice in this context was the prescribing of controlled substances and other drugs and he was not free to ignore contraindications or dosage limits merely by claiming that he was a weight loss or an antiaging physician. We reject the argument that the prescribing of controlled substances is itself a field of practice; this would presumably allow any medical professional with prescribing authority to testify about the standard of care for prescribing drugs in a specialty of which the witness has no knowledge or practical experience. While the applicable definition of incompetence is regulatory rather than statutory, it is noteworthy that in the analogous context of medical malpractice cases the legislature has mandated that only those experts who practice in the defendants field or specialty are qualified to offer opinions on the standard of care. AS 09.55.540(a)(1). It would seem incongruous to require something less when a physicians license is at stake.
AS 08.64.326(a)(8)(A).
As the ALJ properly noted, Dr. Nolans opinion was the view of the American Association of Clinical Endocrinologists. Dr. Odom and Dr. Rouzier subscribe to an alternative view, accepted by many clinicians in their field of practice.
