Controlling large malpractice claims: the unexpected impact of damage caps.

Area of Science:

• Medical Malpractice Law
• Health Economics
• Comparative State Policy Analysis

Background:

• Indiana enacted comprehensive malpractice reforms in 1975.
• Reforms included damage caps, mandatory medical review, and a state insurance fund.
• These reforms aimed to manage medical malpractice litigation outcomes.

Purpose of the Study:

• To compare medical malpractice claim severity in Indiana versus neighboring states.
• To evaluate the impact of Indiana's reforms on claim payment amounts.
• To determine if Indiana's claim payments remain higher independent of other factors.

Main Methods:

• Comparative analysis of medical malpractice claim data from Indiana, Michigan, and Ohio (1977-1988).
• Statistical analysis including calculation of mean claim severity.
• Regression analyses to control for claimant and claim characteristics.

Main Results:

• Indiana's mean claim severity ($404,832) was significantly higher than Michigan's ($290,022) and Ohio's ($303,220).
• Indiana claim payments were higher even after accounting for claimant sex, age, injury severity, negligence allegations, and settlement year.
• Interstate variations in claim and claimant characteristics were observed but did not fully explain the payment differences.

Conclusions:

• Indiana's malpractice reforms did not result in lower average payouts for large claims compared to adjacent states.
• Claim payment amounts in Indiana appear higher due to factors beyond those typically controlled in comparative analyses.
• Further research may be needed to understand the specific drivers of higher claim severity in Indiana post-reform.
