INTRODUCTION In recent decades, the number of professional liability disputes has increased, especially in the civil sector. In these liability assessments, medico-legal experts have become the linchpin. Law No. 24/2017, concerning professional liability in Italy, requires that guidelines and best practices be established to identify the necessary elements for writing expert reports in the legal sector. MATERIALS AND METHODS The authors have created a numerical indicator to be applied to 150 legal expert reports on professional liability, enabling them to evaluate the methodological quality of those reports. The results are then compared with the outcome of the legal proceedings in order to establish the suitability of this quality index for evaluating the work of medico-legal experts. RESULTS Of the 150 reports considered, 14 were scored inadequate, 75 adequate and 31 good. These inadequate (according to the indicator) reports presented a higher probability of being scored inadequate in court proceedings, compared to the risk of inadequacy of all the reports OR 4.6 (95% CI 1.25 - 16.90). This probability significantly increased on comparing the inadequate reports with the adequate OR 5.6 (95% CI 1.28 - 24.41), and the inadequate with the good OR 7.73 (95% CI 1.50 - 39.87). DISCUSSION Application of the proposed indicator is simple and produces a high-quality result, thus ensuring an accurate and tenable appraisal of methodological quality. CONCLUSION The indicator proposed serves as a useful starting point for creating the necessary methodological standards for medico-legal experts in the field of professional liability as recommended by Law No. 24/2017.
