Defensive medicine and its related risk factors: evidence from a sample of Iranian surgeons

Abstract

ABSTRACT Objectives Defensive medicine (DM) is the deviation of a physician from normal behavior or what is a good practice and is aimed at reducing or avoiding the risk of legal litigation from patients or their families. Therefore, this study aimed to determine DM-related behaviors and associated risk factors among Iranian surgeons. Methods In this cross-sectional study, 235 surgeons were selected using convenience sampling. The data gathering tool was a researcher-made questionnaire confirmed as a reliable and valid tool. Factors associated with DM-related behaviors were identified using logistic regression analysis. Results DM-related behaviors ranged from 14.9% to 88.9%. The most common positive DM-related behaviors, including unnecessary biopsy (78.7%), imaging and laboratory tests (72.4% and 70.6%), and refusing high-risk patients (61.7%), was the most common negative DM-related behavior. The likelihood of DM-related behaviors was more in younger and less experienced surgeons. Other variables, such as gender, specialty, and lawsuit history, positively affected some DM-related behaviors (p < 0.05). Conclusion This study showed that the proportion of surgeons who frequently performed DM-related behaviors was higher than those who rarely performed it. Therefore, strategies including reforming the rules and regulations for medical errors and litigations, developing and implementing medical guidelines and evidence-based medicine, and improving the medical liability insurance system can reduce DM-related behaviors.
