Defensive Medical Practice in Dentistry: A Dual-Perspective Cross-Sectional Analysis of Dentists and Patients in...

Background: Fear of malpractice and its potential legal, financial, and reputational consequences are associated with one of the most complex phenomena in the medical community: defensive medical practice (DMP). DMP is frequently analyzed in the specialized literature from the physician's perspective; however, the patient's role in triggering and maintaining defensive behaviors remains under-explored. Methods: This cross-sectional study examined contextual factors associated with fear of malpractice and the convergences between doctors' and patients' perspectives within a bilateral model (error-fear-perceived risk-prevention behaviors), without assuming direct causal relationship. Two questionnaires were administered in Romania to 240 dentists (March-June 2023) and 344 patients (June-December 2023). Associations were tested with chi-square and Fisher's exact tests (reporting Cramér's V and odds ratios), multivariate binary logistic regression, and post hoc power analysis. Results: Over half of dentists (53.3%) reported fear of malpractice despite minimal actual legal exposure (0.8%); this fear was associated with awareness of its potential consequences and perceiving patients as more demanding. In multivariate analysis, fear was the strongest independent predictor of perceiving patients as a threat (aOR = 3.98, 95% CI [1.67-9.48]). On the patient side, 57.9% would avoid a dentist with a known malpractice case and 34.0% had requested additional procedures for reassurance. Conclusions: The interaction between physician fear and patient pressure suggests the existence of a "reassurance loop", in which the patient's need for safety and the doctor's fear can mutually reinforce each other, fostering defensive behaviors. We propose an exploratory typology of patient-induced DMP-direct induction (explicit requests for additional investigations/procedures) and indirect induction (relational pressure and reassurance seeking)-to guide future research. By integrating the dentist and patient perspectives within a bilateral model, the study provides a context-specific account of patient-induced defensive practice in Romanian dentistry and identifies dual-target educational interventions (addressing both clinician communication and patient health literacy) as a potential preventive direction.
