delivered the Opinion of the Court.
In Colorado State Board of Medical Examiners v. McCroskey, No. 92CA1433 (Colo.App. June 17, 1993) (not selected for publication), the court of appeals reversed the final order of the Colorado Board of Medical Examiners (the Board) directing that a letter of admonition be issued to Dr. Brian L. McCroskey for unprofessional conduct. We granted certiorari in order to determine whether the Board was bound by the finding of the administrative law judge (the ALJ) on the existence and nature of a “generally accepted standard of medical practice.” We now reverse and remand this case to the court of appeals with directions.
I
McCroskey is a physician licensed to practice medicine in Colorado and thus is subject to the Medical Practice Act, sections 12-36-101 through -137, 5B C.R.S. (1991 & 1993 Supp.). In 1990, an inquiry panel of the Board 1 issued a letter of admonition to McCroskey based upon a series of well-publicized incidents arising from the care of a stab-wound victim at Denver General Hospital (DGH) in 1988. Although the patient’s initial condition was thought to be stable, he bled to death several hours after his admission. As the attending surgeon on the date of the events in question, McCroskey had the final word on the patient’s treatment and was responsible for the accurate completion of the patient’s medical record. McCroskey declined to accept the letter of admonition and, *1192 pursuant to section 12-36-118(4)(c)(III), 2 a formal disciplinary hearing was held.
Initially, the inquiry panel charged McCroskey with four counts of unprofessional conduct under section 12-36-117(l)(p), alleging that McCroskey committed two or more acts which failed to meet generally accepted standards of medical practice. 3 One count was dismissed either prior to or at the hearing before the ALJ and alleged that McCroskey requested that a pathologist alter the patient’s official autopsy report. A second count, which the ALJ found was not supported sufficiently by the evidence,. charged that McCroskey unreasonably delayed getting to the hospital after being called by the chief resident.
The remaining two counts involved alterations or additions to the patient’s medical record. First, the ALJ found that medical record-keeping is part of “medical practice,” and thus falls within the scope of section 12-36-117(l)(p). The ALJ further found that McCroskey committed an act which failed to meet generally accepted standards of medical practice when he erased and wrote over a pre-operative note made, by another physician concerning the patient’s estimated blood loss. 4
After listening to conflicting expert testimony, the ALJ concluded that McCroskey did not violate generally accepted standards of medical practice by adding a “staff note” to the patient’s medical record days or weeks after the patient’s death and backdating the note to the date of death.
5
“While the better practice is to date such an entry as of the date it is made, in practice many physicians date their entries as of the date of the occurrence.” According to the ALJ, this fact brought McCroskey’s conduct within the standard of care under the “respectable minority” rule articulated in
Hamilton v. Hardy,
On review of the ALJ’s decision, the Board accepted the ALJ’s evidentiary finding that many physicians date a medical record entry to reflect the date of the medical event, rather than the date on which the entry was made. The Board disagreed, however, with the ALJ’s conclusion that this fact brought McCroskey’s conduct within generally accepted standards of medical practice. Instead, the Board determined that “the weight of the evidence supports the conclusion that backdating a medical record entry falls below generally accepted standards of practice.” 6 *1193 Having thus found two acts which fell below generally accepted standards of medical practice, the Board concluded that McCros-key committed unprofessional conduct under section 12-36-117(l)(p), and issued a letter of admonition.
On appeal, the court of appeals concluded that the Board erroneously rejected the ALJ’s finding that MeCroskey’s backdating of the staff note did not violate generally accepted standards of medical practice. McCroskey, slip op. at 4. Specifically, the court of appeals held that “[t]he existence of a ‘generally accepted’ standard of care and its nature is an evidentiary, not an ultimate, fact that must be supported by substantial evidence.” Id. Since the ALJ’s determination of the standard of practice was not contrary to the weight of the evidence, the court concluded that the Board was bound by this finding under section 24-4-105(15)(b), 10A C.R.S. (1988), of the State Administrative Procedure Act. Id. at 5. Consequently, the court reversed the Board’s order and directed the Board to withdraw its letter of admonition and to delete any reference to the letter in MeCroskey’s files.
II
As a state agency with statewide territorial jurisdiction, the Board’s actions are governed by the State Administrative Procedure Act, sections 24-4-101 to -108, 10A C.R.S. (1988 & 1993 Supp.). Section 24-4r- 105(15)(b) of the Act sets forth the appropriate scope of review to be employed by the Board when reviewing an ALJ’s decision:
(b) The findings of evidentiary fact, as distinguished from ultimate conclusions of fact, made by the administrative law judge or the hearing officer shall not be set aside by the agency on review of the initial decision unless such findings of evidentiary fact are contrary to the weight of the evidence.
§ 24-4-105(15)(b), 10A C.R.S. (1988).
As this section makes clear, the Board’s ability to review and to set aside an ALJ’s finding turns on whether the finding is one of “evidentiary” or “ultimate” fact. A finding of evidentiary fact cannot be set aside by the Board on review of an ALJ’s decision unless the finding is contrary to the weight of the evidence in the record. § 24-4-105(15)(b); Colo
rado State Bd. of Nursing v. Lang,
The distinction between evidentiary facts and ultimate conclusions of fact is not always clear.
Federico v. Brannan Sand & Gravel Co.,
In contrast, findings of ultimate fact involve a conclusion of law, or at least a mixed question of law and fact, and settle the rights and liabilities of the parties.
Blaine v. Moffat County Sch. Dist.,
In its final order, the Board treated the ALJ’s findings concerning whether physicians backdate medical records as a finding of evidentiary fact. However, the Board regarded' the ALJ’s. conclusion concerning whether such conduct amounted to substandard care as an ultimate fact, not binding on the Board:
The Board does not' dispute the ALJ’s finding of evidentiary fact that many physicians may date a medical record entry to reflect the date of the medical event in question, rather than the date upon which the entry in the record was made. However, as noted above, the Board disagrees with the ALJ’s conclusion that backdating a medical record entry does not fall below generally accepted standards. Rather, the weight of the evidence clearly supports the conclusion of law that backdating a medical record fails to meet generally accepted standards of practice.
Several reasons cause us to agree with the Board and to hold that the ALJ’s finding on the nature and existence of the “generally accepted standards of medical practice” is a finding of ultimate fact.
First, a determination of the nature and existence of the “generally accepted standards of medical practice” is best viewed as a mixed question of law and fact; it is not simply a factual finding of raw historical data. It is a question of fact to the extent that the applicable standard usually must be established by expert testimony,
7
United Blood Services, a Div. of Blood Systems, Inc. v. Quintana,
Furthermore, determining the standard of care often entails applying legal principles to the evidentiary facts, as the case now before us demonstrates. Here, the AL J reached his conclusion that McCroskey did not violate the standard of care by applying the “respectable minority” test found in
Hamilton v. Hardy,
In
Quintana,
this court made it clear that the standards of medical practice cannot be determined simply by counting how many physicians follow a particular practice. “[N]egligenee cannot be excused on the grounds that others practiced the same kind of negligence.”
Quintana,
This is not to say that the existence and nature of a generally accepted standard of care is always a matter of ultimate fact. As we have previously recognized, a particular fact may be an evidentiary fact in certain circumstances, and an ultimate conclusion of fact in others.
Baca v. Helm,
Treating the generally accepted standard of medical practice as an ultimate fact is also consistent with the disciplinary scheme established by the Medical Practice Act. The importance of the distinction between ultimate and evidentiary facts is that it determines whether it is the ALJ or the agency which has discretion over the matter to be determined.
Federico,
(2) The board shall be comprised at all times of seven members having the degree of doctor of medicine, and two members having the degree of doctor of osteopathy, all of whom shall have been licensed and actively engaged in the practice of their professions in this state for at least three years next preceding their appointments ....
In contrast, an ALJ is not required to have any medical training or knowledge. See § 24-30-1003(2), 10A C.R.S. (1993 Supp.) (ALJs need only be attorneys in good standing, with five years’ experience practicing law). It would be pointless for the General Assembly to create a group of such experienced physicians, only to bind the Board’s discretion by the ALJ’s interpretation of the standard of medical practice.
Moreover, the Board must have discretion to determine the generally accepted standard of medical practice in order to properly enforce the Medical Practice Act. The legislative declaration creating the Board states that the purpose of the Act is to protect the public “against unauthorized, unqualified, and improper practice of the healing arts in this state.” § 12-36-102, 5B C.R.S. (1991);
Hoffner,
Finally, if the discretion to determine the generally accepted standard of medical practice is removed from the Board, physicians will be subject to varying interpretations of the standard by different ALJs. This will result in decisions which are not uniform, even though the facts may be similar. The importance of uniformity was voiced by the concurring justices in Baca in the context of disability benefits:
[T]he legislature granted the commission the power to make independent ultimate conclusions of fact. Thus, there will be uniform decisions made by the commission concerning issues of causation which arise under similar fact patterns. This legislative purpose is particularly important in claims involving occupational diseases. If causation is limited to the status of an evidentiary fact in any case, then whether similarly situated claimants recover benefits under the Act is wholly dependent upon the referee to whom the case is assigned.
Baca,
Having concluded that the existence and nature of a “generally accepted standard of practice” is a question of ultimate fact, we must next consider whether the Board’s findings were supported by substantial evidence in the record. If they were, then the Board’s decision must be upheld.
See Lee,
In our view, there is ample evidence in the record to support the Board’s conclusion that McCroskey violated generally accepted standards of medical practice by backdating an entry in the patient’s medical record. .All three of the inquiry panel’s expert witnesses testified that the generally accepted standard of practice requires that a medical record entry be dated with the date it is made. Even one of MeCroskey’s expert witnesses acknowledged that misdating the record entry was “certainly something [McCroskey] shouldn’t have done.” MeCros-key did not simply backdate a trivial note in a patient’s medical record. Instead, MeCros-key’s actions took place in the context of a patient’s death which resulted in a coroner’s autopsy, peer review activities, publicity, and several legal actions. McCroskey was the attending physician responsible for the accuracy of the patient’s medical record, and yét he engaged in conduct which cast doubt upon the medical record’s integrity. Under these circumstances, the Board' was justified in considering MeCroskey’s conduct to violate the standard of care.
The ALJ relied heavily on the fact that many physicians in practice date their entries as of the date of the medical occurrence, even though “the better practice is to date such an entry as of the date it is made.” However, the fact that “many” physicians may backdate their entries does not, in itself, bring the practice within the appropriate standard of care.
See Quintana,
Since the Board’s decision was supported by substantial evidence, we hold that the court of appeals erred in reversing the Board’s order. Accordingly, we reverse the *1197 court of appeals and remand the case for further proceedings consistent with this opinion. 9
Notes
. The Board is divided into two panels for disciplinary proceedings: an inquiry panel and a hearings panel. The inquiry panel is responsible for investigating complaints to determine whether formal charges are wanranted. The hearings panel conducts the formal hearing and determines the discipline to be imposed. In lieu of the hearings panel, the case can be referred to an ALJ for an initial decision which is then reviewed by the Board. § 12-36-118(1), 5B C.R.S. (1991);
Norton v. Colorado State Bd. of Medical Examiners,
. This section provides:
(c) On completion of an investigation, the inquiry panel shall make a finding that:
[[Image here]]
(III) The investigation discloses an instance of unprofessional conduct which, in the opinion of the inquiry panel, does not warrant formal action by the board but which should not be dismissed as being without merit; in such case, a certified letter ... of admonition shall be sent to the physician against whom a complaint was made ... but ... such physician shall be advised that he has the right to request in writing ... that formal disciplinary proceedings be initiated against him to adjudicate the propriety of the conduct upon which the letter of admonition is based....
§ 12-36-118(4)(c)(III), 5B C.R.S. (1991).
. Section 12-36-117(l)(p) defines “unprofessional conduct" as follows:
(p) An act or omission constituting grossly negligent medical practice or two or more acts or omissions which fail to meet generally accepted standards of medical practice, whether the two or more acts or omissions occur during a single treatment of one patient, during the course of treatment of one patient, or during the treatment of more than one patient;
§ 12-36-117(l)(p), 5B C.R.S. (1991).
. Specifically, the original record entry was completed by a surgical resident on the date of the patient’s death and stated that the patient’s blood loss just prior to surgery was “now greater than 3000 ccs." Sometime after the autopsy, McCros-key changed the record to read that the patient’s blood loss was "now greater than 2000 ccs.”
. This note purported to explain the course of the patient's care and the cause of his death.
. According to the Board, medical record integrity was especially important in this case since the patient died under circumstances raising questions about the quality of care rendered by hospital staff. The cause of the patient’s death, whether due solely to the stab wound or contrib *1193 uted to by neglect of the hospital staff, figured significantly in DGH’s peer review and in subsequent criminal and civil proceedings. By making the medical record entries in the fashion which he did, the Board maintains that McCros-key "unnecessarily clouded the integrity of the record and confused an accurate determination of the cause of the patient's death.”
. Thus, there is no merit to McCroskey’s argument that due process prohibits the Board from substituting its own judgment on the standard of care. The Board may draw a different conclusion from the evidence presented to the ALJ.
Colorado State Bd. of Medical Examiners v. Hoffner,
. However, evidence of a physician’s compliance with the community standard is not conclusive proof of due care. Expert opinion testimony may show that the entire community standard is deficient.
Quintana,
. On appeal, McCroskey also argued that the Medical Practice Act did not purport to regulate the manner of record-keeping until the adoption of § 12-36-117(l)(cc), 5B C.R.S. (1991), in 1989. McCroskey, slip op. at 2. The court of appeals did not reach this issue, however, because it held that the Board was bound by the AU’s finding of the standard of care. Since we reverse the court of appeals and hold that the standard of care is an ultimate fact, it will be necessary for the court of appeals to address McCroskey's argument on remand.
