Study Links Higher Physician Supply to Limits on Non-Economic Damages

States that have enacted limits on non-economic damages in medical lawsuits have about 12 percent more physicians per capita than states without such a cap, according to a study released today by HHS' Agency for Healthcare Research and Quality (AHRQ).

The study is the first of its kind to associate caps on non-economic damages with increased physician supply. It looks at the growth of physician supply since 1970, before any state had enacted caps, and finds that physician supply has grown more in states with caps than in states without caps. The study analyzes state experiences over the past 30 years and adjusts for the impact of multiple factors that are believed to affect physician supply (such as per capita income and physician residency training programs).

The authors find that by 2000, states that had enacted caps had a significantly higher number of doctors per 100,000 county residents (135) compared to states that didn't enact caps (120). By contrast, in 1970, there was no statistically significant difference between states in their per capita supply of physicians.
