P-275 Determination and Indemnity of Occupational Diseases (A Study on Expert Assessments at Ibn Rochd University Hospital’s Medico-Legal Service Over a 10-Year Period)

Introduction Occupational diseases are defined as being caused by work, either due to the use of harmful substances or specific work-related conditions. The indemnity for these diseases requires meeting certain criteria, which involve various medico-legal assessments. Methods This retrospective study examined expert assessments conducted over ten years (2013-2022) at the Ibn Rochd University Hospital’s medico-legal institute in Casablanca. The assessments aimed to determine the presence or absence of occupational diseases, and to potentially specify partial permanent disability rates. Results Among the cases studied, 64% concluded to the presence of an occupational disease, 67% of which were attributed to chemical agents. Allergenic agents (50.74%) were the primary cause. Average exposure duration was 20.8 years (6 months to 44 years). The mean partial permanent disability rate was 26% (5%-75%). Four deaths directly linked to occupational diseases were observed. We noted a male predominance with a sex ratio of 3.48, and the average age is of 53.78 years (28-81). Discussion Only 64% of the cases met the criteria for occupational disease recognition and thus their eligibility for partial permanent disability determination. Understanding indemnity processes aids in supporting victims in their medico-legal journey. Conclusion Preventive investment is crucial, considering the impact of occupational diseases in terms of health and of socio-economic expenses Keywords: Occupational disease _ Exposure _ PPD _ Indemnity _ Repair
