Over a period of two months in 1988 and 1989 general practitioners in the Norwegian county of Møre and Romsdal recorded all contacts with their patients. Participation was close to 100%. We report data from 10,850 surgery consultations with elderly patients (65 years and older). 60% of the consultations involved female patients, and 58% of the patients were 65-74 years old. New diagnoses were made in one-third of the cases; two-thirds were follow-ups. The most common groups of diagnoses were cardiovascular (28%), musculoskeletal (13%), psychiatric (8%) and respiratory diseases (8%). Almost 10% of all consultations were for hypertension. Drugs were prescribed in 45% of all cases. 27% of all prescriptions were for cardiovascular drugs, and 25% were for drugs for the nervous system. The 20 most common diagnoses made up more than half of the total number of diagnoses. Almost 70% of all prescriptions were for the ten most common therapeutic groups.
