2025 Aon/ASHRM HPL Benchmark Analysis

2025 Aon/ASHRM HPL Benchmark Analysis

Aon’s actuaries are pleased to release the 26th annual Aon/ASHRM Hospital and Physician Professional Liability Benchmark Analysis, produced in collaboration with the American Society for Health Care Risk Management (ASHRM).

This report, made possible by the ongoing engagement of our benchmark participants, serves as a key resource for the healthcare sector by providing insights into medical professional liability claim cost trends.

The benchmark analysis is designed to be a practical tool for healthcare risk managers, enabling them to better understand and compare their organizations’ cost of risk against industry standards. By examining and comparing claim and exposure data, risk managers and stakeholders can develop strategies to manage costs and improve outcomes. This year’s report analyzes 117,700 hospital and physician professional liability claims totaling $32.9 billion in incurred losses, as well as 14,700 general liability claims amounting to $719.5 million in losses, all from incidents occurring between 2015 and 2024.

This report provides actuarial and underwriting insights on:

  • Countrywide HPL and PPL benchmark claim frequency, severity and loss rates based on this year’s database of 125 systems.
  • Countrywide GL loss rates as a percentage of HPL loss rates.
  • Forecasted 2026 excess layer loss rates in $5 million increments up to $25 million.
  • Hospital at Home: Risk and Liability Considerations for an Evolving Acute Care Delivery Model
  • Sexual Abuse & Misconduct in Healthcare: Protecting Patients, Providers, and your Organization
  • Preliminary findings on the modernization of MICRA
  • Expanding the high risk territory in Illinois
  • Healthcare risk management department characteristics, including risk professionals and Certified Professional in Healthcare Risk Management (CPHRMs) employed, revenue changes, and days cash on hand.
  • Insurance structures, alternative risk vehicles, and treatment of allocated loss adjustment expenses of healthcare entities.
  • Benchmark frequency, severity, and loss rates by hospital service line, demographics, and size of hospital.
  • Benchmark statistics for thirty-six individual states that include territory breakouts for Florida and Pennsylvania with data volume for each of these geographies lending itself to credible actuarial analyses while also maintaining participants’ confidentiality.
About the Benchmark

This benchmark study is produced under a co-marketing agreement between Aon and The American Society for Health Care Risk Management (ASHRM). Participation in this benchmark was open to all ASHRM members.

The study functions as a practical benchmarking tool, giving healthcare risk managers greater insight into their risk-related costs in the context of industry norms. Through detailed measurement and analysis of claims and exposures, stakeholders are positioned to develop forward-thinking strategies that help minimize costs and optimize claim outcomes.

We are grateful to benchmark participants for their interest in engaging with us on this survey and for making the time and effort to provide their data and responses to us.
