When the utilisation of psychiatric and other medical services is regarded in relation to unemployment, it has been repeatedly found that unemployment, underemployment and disability are strongly connected to service use. An analysis of all psychiatric hospitalisations in Switzerland between 2000 and 2004 showed an up to 17-fold hospitalisation risk for unemployed persons in comparison with full-time employed patients (Kuhl and Herdt, 2007). In this analysis, the work-related difference in hospitalisation days is substantial.
