Rule of Law:
An expert witness is competent to testify on the standard of care in a medical malpractice action even if not of the same specialty as the defendant, provided they are familiar with the applicable standard through experience, education, or if the standard of care is consistently applied across relevant specialties. Hospitals may be held vicariously liable for the negligence of emergency room physicians under principles of ostensible agency, and the physician group directly employing the negligent physician is liable under respondeat superior.
Facts:
- The four-and-a-half-month-old daughter of John and Stephanie Barrett died due to alleged medical malpractice.
- Dr. Adelberto Gonzalez, a third-year surgical resident, treated the infant in the emergency room.
- Dr. Gonzalez was employed part-time by Maryvale Emergency Physicians, Ltd. (Maryvale).
- Maryvale Emergency Physicians, Ltd. was a group of doctors under contract with Samaritan Health Services, Inc. (Samaritan) to provide emergency medical care at Maryvale Samaritan Hospital, owned by Samaritan.
- Samaritan Health Services provided the emergency room facilities, equipment, nurses, and all other support personnel, and promulgated rules and procedures to be followed by Maryvale physicians in treating emergency room patients.
- The infant's family did not have the opportunity to choose which physician treated the child; the hospital determined that a physician associated with Maryvale would examine her.
- Constance Cockrum, the infant's grandmother, had taken the infant's temperature using a thermometer the day before her death, and the accuracy of her reading became a point of contention during the trial.
Procedural Posture:
- Plaintiffs John and Stephanie Barrett presented claims of medical malpractice to a medical liability review panel pursuant to A.R.S. § 12-567.
- The panel found in favor of the plaintiff and against "defendant Dr. Gonzalez" on the claim of negligence, despite Dr. Gonzalez not being a named defendant in the lawsuit.
- The panel rejected other claims against Samaritan Health Services and Maryvale Emergency Physicians, Ltd., which were not based on derivative liability for Dr. Gonzalez's acts.
- A jury trial was subsequently held, resulting in a verdict for the plaintiff against both Samaritan Health Services and Maryvale Emergency Physicians, Ltd., with damages awarded.
- The trial court vacated a provision of its prior partial summary judgment regarding a jury instruction on Samaritan's right to indemnification from Maryvale.
- Samaritan Health Services and Maryvale Emergency Physicians, Ltd. moved for directed verdicts, which the trial court denied.
- Samaritan Health Services and Maryvale Emergency Physicians, Ltd. appealed the trial court's judgment.

Issue:
1. Does a pediatrician possess the requisite competence to testify on the standard of care applicable to a surgical resident in an emergency room setting if they are familiar with the standard of care for the condition in question across relevant specialties? 2. Did the trial court improperly comment on the evidence or err by including the substance of a Medical Liability Review Panel's finding against a non-defendant physician in jury instructions? 3. May a hospital be held vicariously liable under ostensible agency for the negligence of an emergency room physician provided by a contracted physician group, and is that physician group then directly liable for its employee's negligence under respondeat superior?
Opinions:
Majority - Haire, Judge
Yes, the trial court did not err in determining that Dr. Mark Kishel, a pediatrician, was competent to testify concerning the standard of care applicable to Dr. Gonzalez, a surgical resident. A.R.S. § 12-563 requires proof that a healthcare provider failed to exercise the care expected of a reasonably prudent provider 'in the profession or class to which he belongs.' However, an expert does not need to be of the exact same specialty as the defendant if they are familiar with the standard of care through their 'education, experience, observation or association with that specialty,' or if the standard of care for the defendant's specialty is the same as one with which the expert is familiar. Dr. Kishel testified he assisted in supervising and instructing interns and residents on similar conditions, was familiar with the standard of care in emergency room situations for such infants, and stated the infant's condition was common for pediatricians, family physicians, and emergency room physicians. The court concluded that Dr. Kishel's experience demonstrated his familiarity with the applicable standard of care. No, the trial court did not improperly comment on the evidence nor did it err in instructing the jury concerning the Medical Liability Review Panel's decision against Dr. Gonzalez. During cross-examination of the infant's grandmother, the judge clarified a thermometer exhibit by stating it looked unshaken and reading about 108 degrees. The court found this was merely an attempt to clarify an exhibit and not an expression of opinion on its significance, which would violate Article 6, § 27 of the Arizona Constitution. Regarding the jury instruction on the Medical Liability Review Panel's conclusion, A.R.S. § 12-567(K) permits the panel's conclusions to be admitted into evidence and requires the jury to be instructed that the conclusion is not binding. Since the panel's finding against Dr. Gonzalez was uncontroverted and frequently referred to by counsel, the instruction merely informed the jury of an uncontroverted fact and properly advised them of its non-binding nature, which was a necessary predicate to the statutory admonition. This did not constitute an undue emphasis or comment on the evidence. No, the trial court did not err in advising the jury of the Medical Liability Review Panel's decision against Dr. Gonzalez, even though he was not a named defendant. A.R.S. § 12-567(F) states the panel determines findings against each 'defendant,' but the court found nothing in the statute to preclude the panel from evaluating the conduct of a non-defendant physician when the named defendants are alleged to be vicariously liable for that physician's negligence. The panel was obligated to render a finding on the claim alleging Dr. Gonzalez's negligence, as the plaintiff had made a claim based on his conduct. Although the court recognized the panel's formal order was erroneous in calling Dr. Gonzalez a 'defendant,' it concluded this was not prejudicial to the actual defendants and did not affect the validity of the finding on Dr. Gonzalez's conduct. No, the trial court did not err in refusing to direct a verdict for Samaritan Health Services. The plaintiff presented sufficient evidence to support a finding of vicarious liability against Samaritan based on the principles of ostensible agency established in Beeck v. Tucson General Hospital. Evidence showed Samaritan provided the emergency room facilities, equipment, and support personnel; promulgated rules for the physicians; and the patient did not choose her physician but was treated by one associated with Maryvale in Samaritan's ER. These facts align with the conditions for establishing ostensible agency. No, the trial court did not err in refusing to direct a verdict for Maryvale Emergency Physicians, Ltd. The principles from Donn v. Kunz and Barker v. General Petroleum Corp. (an agent not liable for subagent unless fraud/gross negligence) do not apply here because Dr. Gonzalez was a direct employee of Maryvale Emergency Physicians, not a sub-employee or sub-agent of Samaritan. Therefore, ordinary principles of respondeat superior apply, holding Maryvale vicariously liable for the negligent conduct of its employee, Dr. Gonzalez. To rule otherwise would defeat established principles of respondeat superior and vicarious liability. The court also noted that Samaritan was entitled to indemnification from Maryvale, meaning Maryvale would ultimately be the liable party.
Analysis:
This case significantly clarifies the application of expert witness competency rules in medical malpractice, particularly allowing experts from related but not identical specialties to testify where standards of care overlap or the expert has relevant supervisory experience. It reinforces the doctrine of ostensible agency, holding hospitals vicariously liable for the negligence of emergency room physicians even if they are technically independent contractors, when patients reasonably rely on the hospital's representation of comprehensive care. Furthermore, it affirms the direct respondeat superior liability of physician groups for their employees' negligence, even when the hospital is also found liable under ostensible agency. The case also provides important guidance on the procedural use of Medical Liability Review Panel findings in jury instructions, emphasizing their non-binding nature while allowing their substance to be communicated to the jury.
