[Features and evaluations of organizational support provided by occupational health nurses in private practice for the implementation of sustainable health and productivity management in medium-sized enterprises].

This study aimed to clarify the features and evaluations of the organizational support provided by occupational health nurses (OHNs) in private practice to promote sustainable health and productivity management (HPM) in medium-sized enterprises. Corporate managers and employees of four enterprises with fewer than 300 employees received support from an experienced OHN in private practice through five support sessions per company, primarily targeting company managers. The OHNs documented their support steps and evaluations. After completing the support process, we conducted semi-structured interviews with company managers and OHNs to evaluate the support provided by the OHNs. The support processes were organized for each company according to an analytical framework based on the consolidated framework for implementation research; the support features of OHNs were extracted. The evaluations of the support provided by OHNs from the perspective of company personnel were categorized using content analysis. Six features of support by OHNs for the promotion of HPM were extracted, including clarifying corporate needs while focusing on relationships of trust with company representatives, providing appropriate health information, and introducing external resources to facilitate independent and continuous efforts in the company to promote sustainable HPM. The managers' evaluations of the support provided by the OHNs included the following six categories: 1) identified and recognized current internal health issues; 2) received specific assistance tailored to the company; 3) gained an opportunity to work on health promotion measures; 4) considered the development and continuation of future health promotion measures; 5) learned about the existence of OHNs as easy to consult with; and 6) identified aspects of support from OHNs that were different from what they expected. This study clarified the features and evaluations of the support provided by OHNs in private practice in medium-sized enterprises for the promotion of HPM. Our findings suggest that the involvement of OHNs in private practice may increase the number of medium-sized enterprises that can autonomously commit themselves to HPM in a sustainable manner.
