An Overview of the Protections Afforded by the Peer Review Protection Act

November 1, 2025

As scientific and medical advancements have accelerated, so has the complexity of medical decision-making, exposing a need for standardization in the United States. In 1952, the Joint Commission created the mandatory clinical peer review process. Often referred to as “medical peer review,” it is the process by which health care providers establish and maintain reliable standards of quality in patient care. Clinical peer review entails periodic meetings of professional health care providers to evaluate the quality and efficiency of the services performed by other professional health care providers within the same hospital or health system. Today, countries with reputations for the most exceptional health care all mandate clinical peer review processes. In the United States, the clinical peer review process is so trusted to maintain and improve the quality of health care that every state has enacted a statute preventing certain information and documents discussed in peer review meetings from disclosure in litigation. In 1974, the Pennsylvania legislature enacted the Peer Review Protection Act (PRPA) to provide an evidentiary privilege to protect the “proceedings and documents of a review committee,” conducting peer review activities by professional health care providers, in conformity with its provisions. Reginelli v. Boggs, 181 A.3d 293, 296 (Pa. 2018). The PRPA’s evidentiary privilege is set forth in Section 425.4: The proceedings and records of a review committee shall be held in confidence and shall not be subject to discovery or introduction into evidence in any civil action against a professional health care provider arising out of the matters which are the subject of evaluation and review by such committee and no person who was in attendance at a meeting of such committee shall be permitted or required to testify in any such civil action as to any evidence or other matters produced or presented during the proceedings of such committee or as to any findings, recommendations, evaluations, opinions or other actions of such committee or any members thereof. Between 2018 and 2021, courts both narrowed and broadened the application of this privilege. Narrowing: Only “Peer Review Committees” Can Assert the Privilege In Reginelli v. Boggs, the Pennsylvania Supreme Court held the defendants were not entitled to this privilege primarily because the physician’s employer was not a “professional health care provider” covered under the PRPA. UPMC Emergency Medicine, Inc. (ERMI) staffed the physician to Monongahela Valley Hospital (MVH) and was therefore the physician’s employer. The court held ERMI was not a “professional health care provider” because it was not regulated and licensed to practice medicine. The PRPA defines the term “professional health care providers” as “individuals or organizations who are approved, licensed or otherwise regulated to practice or operate in the health care field under the laws of the Commonwealth.” Because the PRPA’s language explicitly states the “individual or organization be `approved, licensed or otherwise regulated to practice or operate in the health care field under the laws of the Commonwealth- to benefit from the privilege—and the employer at issue was not—the court found the PRPA privilege did not apply. Furthermore, the court found each of the defendants could only be construed as mere “review organizations” that engaged only in a process of reviewing professional qualifications credentialing). Therefore, they were not “review committees” under the PRPA. The PRPA defines a “review organization” as “any committee engaging in peer review....” Although the language of Section 425.4 suggests it pertains to review organizations, the substantive text sets forth confidentiality mandates and testimonial privileges relating to the work and records of review committees. Since the PRPA privilege does not explicitly extend to any review organization that merely conducts credentialing review, the defendants did not qualify for the privilege. Here, the court determined that MVH’s physician merely reviewed the credentials of hospital staff and did not engage in review of the quality and efficiency of the services staff performed. Narrowing: Credentialing Files are Not Protected In Estate of Krappa v. Lyons, the Pennsylvania Superior Court interpreted the PRPA and Reginelli to mean a credentialing file will not be entitled to the PRPA’s evidentiary privilege if it (1) consists entirely of credentialing materials, and (2) was maintained by the hospital’s “credentialing committee.” In Krappa, a patient’s estate brought suit alleging a delay in diagnosis after the patient had died of cancer. During discovery, the estate sought unredacted copies of the medical center’s files concerning two physicians who treated the patient. As discussed in Reginelli, the Superior Court determined credentialing files generated and maintained by a hospital’s credentialing committee are not protected under the PRPA because a credentialing committee does not qualify as a “review committee” engaging in peer review. Narrowing: Event Reports, Root-Cause Analyses are Not Protected In Ungurian v. Beyzman, the Pennsylvania Superior Court articulated that the PRPA privilege does not encompass event reports and root-cause analyses where there is no indication those documents were generated “exclusively for a PRPA 'review committee.' This was a case where the patient’s mother brought a medical malpractice action against physicians, hospital staff, clinics, corporations, and the hospital itself alleging their collective negligence caused the total and permanent incapacity of her child who had undergone a cystoscopy at the hospital. The mother-plaintiff sought to compel various documents, including event reports and root cause analysis, and the defendants appealed arguing protections pursuant to the federal Patient Safety and Quality Improvement Act of 2005 and PRPA. Consistent with the Superior Court’s reasoning in Lyons, the court reasoned that, because neither event reports nor root-cause analyses were generated in the course of peer review and merely constituted business records of the hospital, these documents were not entitled to the privilege. Broadening: Privilege Extends to Peer Review as a Function, not just a “Peer Review Committee” In Leadbitter v. Keystone Anesthesia Consultants, Ltd., the Pennsylvania Supreme Court expanded the potential applicability of the PRPA’s evidentiary privilege in contrast to its opinion in Reginelli where, consistent with the plain language of § 425.3-425.4, the court found the title or name of the body conducting the review was determinative of whether the privilege would apply. Here, however, the Leadbitter court articulated that it is instead the actual function or “activity” of a review organization/committee which determines whether the privilege applies. In this case, a physician applied to be appointed to the medical staff of St. Clair Hospital and for orthopedic surgery clinical privileges. After performing surgery on a patient, the patient suffered a series of strokes and filed a medical malpractice suit against the hospital, seeking that they produce documents relating to the physician’s credentials, as they claimed the physician lacked expertise. The hospital denied the requests, arguing the PRPA privilege applied because the work of their credentials committee was multifaceted and included peer review. Specifically, the hospital argued that this work included both privileging and credentialing and that, because privileging is covered by the PRPA as a peer review activity, the hospital was entitled to statutory protection. It pointed out—and the Leadbitter court acknowledged—that Reginelli’s reasoning was limited to credentialing review for purposes of appointment to a hospital’s medical staff. The Leadbitter court agreed that privileging is distinct from credentialing as it involves giving the physician permission to treat patients at the hospital, and not merely to exercise political rights in relation to staff and committee meetings. As such, it agreed with the proposition that a credentials committee is entitled to the PRPA’s protections to the extent it performs a peer-review function—in this case, privileging. In short, because of Leadbitter, the PRPA’s evidentiary privilege extends to those who engage in “peer review activities” as the actual function of the committee—not the title—determines whether the privilege applies. Narrowing: Private Physician Practice Groups Cannot Assert the Privilege In 2021, the Eastern District considered whether a report authored by a radiologist who reviewed care provided at a hospital was protected under PRPA. In Lasheena Sipp Lipscob v. Einstein Physicians Pennypack Pediatrics, the plaintiff sued both a hospital and a private radiology practice that provided radiology services to the hospital, arguing the defendants failed to diagnose testicular torsion resulting in the loss of a testicle. A report generated by a radiologist employed by the practice was identified in discovery which reviewed the quality of care rendered to the plaintiff’s minor-patient. The defendants argued this report was protected under the PRPA because it was created for a “peer review purpose.” The court disagreed, reasoning first that the radiology group (i.e., a private medical practice) was not a “professional healthcare provider” within the meaning of the PRPA and therefore not eligible for the evidentiary privilege. The Pennsylvania Superior Court ruled consistent with this conclusion in 2021 in the non-precedential decision of Bousamra v. Excela Health. Second, while the hospital defendant was clearly a “professional health care provider” under the PRPA, it too could not assert the evidentiary privilege over this report because the authoring radiologist did not generate the report as part of any hospital “committee” as contemplated under the Act. In other words, because the report was not generated for or provided to any hospital “committee” performing a “peer review function,” the PRPA privilege was not extended. Key Takeaways In enacting the Peer Review Protection Act, the Pennsylvania legislature recognized that candid and rigorous clinical peer review is essential to upholding the quality of patient care. Accordingly, the evolving body of case law interpreting the PRPA’s evidentiary privilege carries substantial implications for health care providers and institutions, particularly in the context of medical malpractice litigation. To preserve the confidentiality afforded by the PRPA, documents assessing the quality of care should be created by or for a hospital committee engaged in peer review functions, such as privileging. As with any legal privilege, the integrity of protection depends on strict adherence to confidentiality—such materials must not be disclosed to unauthorized parties, whether internal or external to the institution.  The Quarterly Dose – November 2025, has been prepared for our readers by Marshall Dennehey.

Ohio Supreme Court Holds That a Binding Appraisal Award May Not Be Set Aside Absent Specific Evidence of Manifest Mistake or Fraud

On July 23, 2026, the Ohio Supreme Court issued a rare opinion on the binding effect of an appraisal award in a property insurance policy.  The Court in One Church held: A binding appraisal award will not be set aside unless an error is so palpably wrong that it undermines the intent of the agreement, such as corruption or gross mistake, not a mere error of judgment—To plead a claim of mistake with particularity as required by Civ.R. 9(B), facts alleged in a complaint must constitute the elements of mistake—Allegation that additional, hidden damage was discovered after appraisal award failed to state a claim of mistake that could justify setting aside binding appraisal.  The case arose out of a claim brought by One Church against its insurer, Brotherhood Mutual Insurance Company for roof damage from a storm. Pursuant to the terms of the insurance policy, the parties agreed to submit the matter to appraisal. The two appraisers inspected the building, and both appraisers agreed that the damages were $313,271.98. The insurer paid the agreed appraised amount.  Thereafter, the insured submitted a claim for an additional $206,663.09 in damages. The insured argued that these additional damages were not discovered until after the repairs began, and that they should be permitted to submit an additional claim, even though there had already been a binding appraisal of damages. The insurer refused to pay the additional damages, and the insured sued for breach of contract and bad faith.  In the trial court, the insurer moved to dismiss for failure to state a claim, arguing that the binding appraisal award barred any further claims. The insured took the position that additional hidden damages could not be discovered until after the repairs began, and therefore there was a mutual mistake. The trial court dismissed the case on the insurer’s motion, because there was no “evidence of fraud, misfeasance, or mistake”. The Court of Appeals agreed that appraisal awards are generally binding, but noted that an appraisal award can be set aside for fraud or manifest mistake. The Court of Appeals reversed and remanded the case to the trial court, finding that the insured had pled mistake with sufficient particularity. The insurer appealed to the Ohio Supreme Court. On appeal, the Ohio Supreme Court reversed the Court of Appeals, and reinstated the trial court decision dismissing the case for failure to state a claim upon which relief can be granted. The Supreme Court found that since the insured had already demanded appraisal, and the appraisal award was binding, “something more than error of judgement, such as corruption in the arbitrator, or gross mistake” must be pled with particularity, and proven for the insured to override the appraisal award. Since the complaint did not allege fraud or manifest mistake with sufficient particularity, something more than a mere error of judgment, the complaint was insufficient to state a claim.  The complaint in this case did not challenge the appraisal award. It pled that additional damages were discovered that were not apparent when the appraisal was done. It did not specify “who discovered the damages, how they were discovered, where they were found, why they were previously hidden, or why they rise to the level of a manifest mistake that the “appraiser would have corrected...had it been called to his attention”. Id at ¶22 citing Lakewood Mfg. Co. v. Home Ins. Co. of New York, 422 F.2d 796, 798 (6th Cir. 1970). Cases deciding the effect of appraisal awards are unusual. The Ohio Supreme Court’s decision in One Church relies primarily on 19th century case law for its conclusion. This emphasizes the fact that there is minimal case law deciding the effect of binding appraisal clauses in property insurance policies, and makes this case all the more significant. A lengthy dissent was written by Justice Fisher, who would have affirmed the Court of Appeals decision reversing and remanding the case for a decision on the merits. Of course, the decision works both ways, and an insurer dissatisfied with a binding appraisal award will likewise be without further recourse absent evidence of corruption, fraud, misfeasance, or manifest mistake, which must be pled with particularity. To constitute manifest mistake, “the mistake must be of such character that the arbitrator or appraiser would have corrected it had it been called to his attention.”  Lakewood Mfg. Co. v. Home Ins. Co. of New York, 422 F.2d 796, 798 (6th Cir. 1970).  The majority opinion does not specifically identify what would have been sufficient to plead mistake with particularity, or if the insured could have amended the complaint to overcome the deficiencies. The dissent argues that this was not really a case alleging mistake, but rather a question of contract interpretation. The insured did not challenge the appraisal, but argued that the hidden damage was not part of the appraisal, and the appraisal only covered the known damages.  However, this argument did not carry the day with the majority.  *Thomas F. Glassman, a shareholder in Marshall Dennehey’s Cincinnati office, filed a brief in the Ohio Supreme Court on behalf of the Ohio Association of Civil Trial Attorneys, in support of the insurer’s position.

No-Cause Jury Verdict Secured in Wrongful Death Trial

We successfully obtained a no-cause jury verdict in a 13-day wrongful death trial. The decedent, a 59-year-old man, was admitted to the emergency room on February 15, 2019, with complaints of abdominal pain, decreased appetite, and constipation, despite the use of laxatives. The patient did not complain of any nausea, vomiting, or diarrhea. He had a significant medical history including diabetes, hypertension, prior coronary artery stenting, morbid obesity (with past gastric bypass surgery), longstanding ventral hernia, and back pain. A CT scan revealed multiple hernias and a potential closed-loop bowel obstruction, leading to a surgery consultation. Our client, an emergency general surgeon, interpreted that the patient did not have a closed loop or any significant obstruction and recommended non-surgical management. The patient was approved to have clear liquids, and had a vomiting incident shortly after, but our client was not notified. The patient was returned to NPO status, and after improving overnight, he was returned to “clears” and additional medical and renal consults were ordered. Our client did not receive any communications from the residents/nurses of any changes in the patient’s condition. On February 18, 2019, two rapid responses were called due to increased heart rate and vomiting. It is believed that the vomiting resulted in aspiration, causing sepsis, ultimately leading to the patient’s death. During the trial, the plaintiff’s sole medical expert highlighted imaging on the wrong hernia, which called into question all of his opinions in the case. We made key objections related to the expert testimony, limiting what the allegations were, and preventing new allegations from being made. After approximately two and a half hours of deliberating, the jury returned a no-cause verdict.
