The largest number of work incapacities was in March and November. The mean period of work incapacity was 21.4 days. The shortest work incapacity was recorded in patients suffering from gout (13.2 days) and the longest one in patients with rheumatoid arthritis (125.4 days). The most frequent cause of work incapacity was back pain (62.2%), extraarticular rheumatism (17.4%) and osteoarthritis of the joints of the extremities (7.2%). Two hundred-sixty-four patients had in-patient treatment (9%). The greatest proportion of patients were hospitalized on account of back pain (54.9%). The mean period of hospitalization was 17.3 days.
