High and low-risk specialties experience with the U.S. medical malpractice system

Area of Science:

• Medical malpractice research
• Physician liability
• Risk management in healthcare

Background:

• Medical malpractice system research often focuses on "high-liability risk specialties."
• Concerns regarding malpractice exist across all medical fields, not exclusively high-risk ones.
• This study investigates differences in malpractice system experiences between high- and low-liability risk specialties.

Purpose of the Study:

• To compare the malpractice claims experience of "high-liability risk" versus "low-liability risk" medical specialties.
• To identify differences in claim outcomes and characteristics based on specialty liability risk.

Main Methods:

• Analysis of malpractice claims data from the Physician Insurers Association of America's Data Sharing Project (1985-2008).
• Utilized linear regression, controlling for year, to assess the impact of liability risk on claim outcomes.
• Examined indemnity payment rates, average payment amounts, and reasons for claim resolution (settlement, dismissal, etc.).

Main Results:

• High-liability risk specialties had a higher rate of indemnity payments (33%) compared to low-liability risk specialties (28%).
• While average indemnity payments were higher in high-risk specialties, the difference was not statistically significant (p=0.25).
• Low-liability risk specialties had more claims dropped or dismissed, whereas high-liability risk specialties had more plaintiff settlements (p<0.001).

Conclusions:

• Medical malpractice risk is prevalent across all specialties.
• Indemnity costs and claim resolution patterns exhibit variability in both high- and low-liability risk specialties.
• Distinct reasons for claim initiation suggest the need for specialized risk management strategies for different medical fields.
