Medical care of employees long-term sick listed due to mental health problems: a cohort study to describe and compare the care of the occupational physician and the general practitioner.

OBJECTIVES: To describe medical management by the general practitioner (GP) and occupational physician (OP) of workers sick listed due to mental health problems, and to determine agreement in diagnosis, main cause of sickness absence and obstacles in return to work.
METHODS: A cohort of 555 employees being sick listed for 12 to 20 weeks due to mental health problems was recruited and followed for 1 year. These employees were interviewed about their mental health and contacts with GP, OP, other specialists and employer. In addition, the GP and/or the OP of 72 employees were interviewed about the medical diagnosis and management.
RESULTS: Most employees sick listed for 12-20 weeks visited their GP and OP. According to the employees most interventions applied by the GP were medical interventions, such as referral of employees and prescription of medical drugs. Working conditions were seldom discussed by the GP and work-related interventions were never applied. Most interventions applied by the OP were work-related interventions and/or contact with the employer. The OP more often talked about working conditions and conflicts. According to the employees, the communication between GP and OP only took place in 8% of the cases. Agreement in the diagnosis, main cause of sickness absence, and obstacles in return to work reported by the GPs and OPs of the same employee was poor. In addition, similarity in reported diagnosis by GP and/or OP and the employees' scores on valid questionnaires on (mental) health was limited.
CONCLUSIONS: The lack of communication and agreement by Dutch GPs and OPs in medical diagnosis and management of employees long-term sick listed due to mental health problems are indicators of sub-optimal medical treatment and return-to-work strategies.
