[Evaluation of disability pensions by a medical polyclinic: 1990-1995].

The question if and in what manner changes of the labour market, in first line increasing unemployment, may influence the composition of the collective demanding a disability pension on one hand and the diagnoses relevant for assessment of requests on the other hand have been investigated as well as possible influences on the criteria for assessments. To this end all expert reports elaborated by the Medical Outpatient Clinic of the University Hospital of Zürich and submitted to the disability insurance between 1990 and 1995 have been evaluated retrospectively. The results show that the fraction of men remained stable around 70% over the whole observation period. The number of persons employed in auxiliary functions remained also constantly high. Over the whole period of observation there was a high, growing percentage of foreign applicants. The most marked change during the observation period was a significant increase of unemployment in the collective. This increase particularly affected applicants with higher ranking jobs or persons over 50. Foreigners became an important part of the unemployed applicants. Rheumatoid disorders and "back pain" in particular were of increasing importance among the relevant diagnoses for assessment of disability. There was a significant decline in the extent of invalidity acknowledged in marked contrast to our initial expectation that the strictness of the applied criteria would weaken when confronted with an increasing number of applications.
