    Abstract:
    OBJECTIVE: Perception of medicolegal risk has been shown to influence defensive medicine behaviors. Canada, South Africa, and the United States have 3 vastly different health care and medicolegal systems. There has been no previous study comparing defensive medicine practices internationally. METHODS: An online survey was sent to 3672 neurosurgeons across Canada, South Africa, and the United States. The survey included questions on the following domains: surgeon demographics, patient characteristics, physician practice type, surgeon liability profile, defensive behavior-including questions on the frequency of ordering additional imaging, laboratory tests, and consults-and perception of the liability environment. Responses were analyzed, and multivariate logistic regression was used to examine the correlation of medicolegal risk environment and defensive behavior. RESULTS: The response rate was 30.3% in the United States (n = 1014), 36.5% in Canada (n = 62), and 41.8% in South Africa (n = 66). Canadian neurosurgeons reported an average annual malpractice premium of $19,110 (standard deviation [SD] = $11,516), compared with $16,262 (SD = $7078) for South African respondents, $75,857 (SD = $50,775) for neurosurgeons from low-risk U.S. states, and $128,181 (SD = $79,355) for those from high-risk U.S. states. Neurosurgeons from South Africa were 2.8 times more likely to engage in defensive behaviors compared with Canadian neurosurgeons, while neurosurgeons from low-risk U.S. states were 2.6 times more likely. Neurosurgeons from high-risk U.S. states were 4.5 times more likely to practice defensively compared with Canadian neurosurgeons. CONCLUSIONS: Neurosurgeons from the United States and South Africa are more likely to practice defensively than neurosurgeons from Canada. Perception of medicolegal risk is correlated with reported neurosurgical defensive medicine within these countries.
