Use of mental health services in south Verona and Groningen. A comparative case-register study

A comparison was made of the utilization of mental health services in a psychiatric case register area in Italy (south Verona) and one in the Netherlands (Groningen). All residents living in these areas who contacted a mental health service in 1982 were traced and followed for a period of one year. The year prevalence rates differed considerably (110/10,000 in south Verona and 329/10,000 in Groningen). Rates of single consulters were similar in both areas, while those of chronic inpatients were more than 11 times higher in Groningen than in south Verona. After excluding both single consulters and chronic inpatients, when comparing service consumption according to fixed classes of scores, the category of highest service use accounted for 60\% of care provided in Groningen as compared with less than 30\% in south Verona. The proportion of total service consumption due to inpatient care was about the same in both areas, but brief admissions were more common in south Verona. Moreover, when service use was considered as a relative construct, about 10\% of patients in both areas could be called high users. Finally, long-term patients were more prevalent in Groningen (26\%) than in south Verona (13\%).
