Prevalence and costs of defensive medicine: a national survey of Italian physicians.

Objective To identify the prevalence of the practice of defensive medicine among Italian hospital physicians, its costs and the reasons for practising defensive medicine and possible solutions to reduce the practice of defensive medicine. Methods Cross-sectional web survey. Main outcome measures Number of physicians reporting having engaged in any defensive medicine behaviour in the previous year. Results A total of 1313 physicians completed the survey. Ninety-five per cent believed that defensive medicine would increase in the near future. The practice of defensive medicine accounted for approximately 10% of total annual Italian national health expenditure. Conclusions Defensive medicine is a significant factor in health care costs without adding any benefit to patients. The economic burden of defensive medicine on health care systems should provide a substantial stimulus for a prompt review of this situation in a time of economic crisis. Malpractice reform, together with a systematic use of evidence-based clinical guidelines, is likely to be the most effective way to reduce defensive medicine.
