A mixed methods process evaluation of a peer coaching intervention to improve the implementation of preventive tasks by occupational physicians

ObjectivesThis study aimed to evaluate the process of implementation of a peer coaching intervention program for occupational physicians (OPs) to improve the execution of preventive tasks. Specifically, the evaluation seeks to: (1) describe the reach and uptake of the intervention program; (2) determine the extent to which the program was implemented as intended; (3) provide insights into experiences of OPs, and (4) identify factors influencing the implementation. MethodsThis study employed a mixed-methods approach to assess seven main process indicators: acceptability, adoption, appropriateness, feasibility, fidelity, penetration and sustainability. Data were collected between March and June 2024 by means of an online questionnaire (N=98), and 17 semi-structured interviews with group coordinators and OPs. Results20 out of 21 groups allocated to the intervention program participated in the intervention and 98 out of 115 participants (85%) filled in the questionnaire. Three-quarters of the participants completed the entire program. 96% of the OPs successfully discussed barriers to the execution of preventive tasks, and 83% were able to formulate strategies for these barriers. Most participants managed to implement their formulated goals in practice. When they were unable to do so, time constraints and resistance from employers and their occupational health services often played a role. OPs valued the programs structure, interaction with colleagues, and the increased awareness it generated. Discussion and conclusionThe peer coaching group program was well-implemented and positively evaluated by OPs. The program can be improved by allocating more time to it, for instance by integrating it into the educational curriculum, and by paying more attention to the specific working conditions of OPs, such as the different sectors in which they are employed.
