Development of evidence-based practice in occupational health services in Sweden: a 3-year follow-up of attitudes, barriers and facilitators.

Purpose: The Swedish government initiated an investigation of how to secure and develop the competence of the occupational health services. The primary aim of the present study was to investigate whether the development of evidence-based practice (EBP) in the Swedish occupational health services in relation to attitudes, knowledge and use improved during the first 3 years of the government's initiative.

Methods: The study has a mixed methods design combining questionnaires and interviews with data collection at baseline and at 3-year follow-up.

Results: The response rate was 66% at baseline and 63% at follow-up. The results show that practitioners' knowledge of EBP was moderate at baseline and improved at follow-up (p = 0.002; 95% CI 0.01; 0.21). Practitioners experienced lower levels of organizational and managerial support for EBP at follow-up (p < 0.001; 95% CI 0.18; 0.38). The results revealed that managers viewed responsibility for implementing EBP as a matter for individual practitioners rather than as an organizational issue.

Conclusions: Occupational health service managers and practitioners are generally positive to EBP. However, the findings emphasize the need to educate managers in how to support EBP at the organizational level by creating an infrastructure for EBP in the OHS.
