Neurosurgical Defensive Medicine in Texas and Illinois: A Tale of 2 States

OBJECTIVE: To compare the self-reported liability characteristics and defensive medicine practices of neurosurgeons in Texas with neurosurgeons in Illinois in an effort to describe the effect of medicolegal environment on defensive behavior. METHODS: An online survey was sent to 3344 members of the American Board of Neurological Surgery. Respondents were asked questions in 8 domains, and responses were compared between Illinois, the state with the highest reported average malpractice insurance premium, and Texas, a state with a relatively low average malpractice insurance premium. RESULTS: In Illinois, 85 of 146 (58.2%) neurosurgeons surveyed responded to the survey. In Texas, 65 of 265 (24.5%) neurosurgeons surveyed responded. In Illinois, neurosurgeons were more likely to rate the overall burden of liability insurance premiums to be an extreme/major burden (odds ratio [OR] = 7.398, P < 0.001) and to have >$ 2 million in total coverage (OR [9.814, P < 0.001) than neurosurgeons from Texas. Annual malpractice insurance premiums in Illinois were more likely to be higher than $50,000 than in Texas (OR = 9.936, P < 0.001), and survey respondents from Illinois were more likely to believe that there is an ongoing medical liability crisis in the United States (OR = 9.505, P < 0.001). Neurosurgeons from Illinois were more likely to report that they very often/always order additional imaging (OR = 2.514, P = 0.011) or very often/always request additional consultations (OR = 2.385, P = 0.014) compared with neurosurgeons in Texas. CONCLUSIONS: Neurosurgeons in Illinois are more likely to believe that there is an ongoing medical liability crisis and more likely to practice defensively than neurosurgeons in Texas.
