Retention among full-time occupational physicians in Japan.

BACKGROUND

To secure human resources for occupational medicine, it is important to analyse occupational physician retention trends and the factors associated with retention. However, little is currently known about this topic.

AIMS

To identify occupational physician retention trends, to identify factors associated with this retention and to discuss the policy implications of the findings.

METHODS

We analysed data from the biannual national physician census surveys conducted by the government of Japan from 2002 to 2014. In this study, those who chose 'working as an occupational physician' as their workplace/type of work from a pre-determined list in the survey questionnaire were considered full-time occupational physicians. We presented retention trends by calculating the annual retention rate for each set of two consecutive surveys. We then used logistic regression to identify factors associated with retention among occupational physicians.

RESULTS

The annual retention rate of full-time occupational physicians from 2012 to 2014 was estimated as 76%, which represents a 6% improvement in retention over the study period. The odds of continuing to practise as an occupational physician were higher for occupational physicians working in cities compared with those working in towns or villages.

CONCLUSIONS

Improving and facilitating smooth transitions between clinical practice and occupational medicine would help to secure human resources in occupational medicine, even if the current trend of low retention continues.
