RESUMO
The analysis of small area variation (SAV) is useful to correlate hospital utilization rates with supply. In this paper the SAV techniques are applied to 26 areas of Catalonia, whose population is covered by the same hospital or group of hospitals in more than 75% of occasions, and hospitalization rates for several surgical procedures (appendectomy, herniorraphy, cholecystectomy, prostatectomy, hysterectomy, tonsillectomy and lens extraction) are analyzed. For these purposes, 26482 discharges recorded in the Minimum Basic Data Set of Hospital Discharges in 1993 were studied. The obtained results show a great variability between areas, which sometimes is larger than the reported in the literature. For amigdalectomy, the ratio between highest and lowest hospitalization rates is 8.8. For prostatectomy and lens extraction the ratios are 4.8 and 4.5, respectively.

The basic epidemiological characteristics of HIV infection and AIDS among children are described with a particular reference to HIV vertical transmission. The HIV transmission pattern identified in our community is described according to the WHO classification scheme. To describe the epidemic, as well as its temporal evolution, 1.933 cases reported to the population based registry of Catalonia and 287 seropositive children and their mothers are used. We have quantified the importance of intravenous drug usage by the parents in relationship to HIV transmission; 54.7% of the mothers of HIV positive children were intravenous drug users. We predict that during the coming years there will be a continuous increase in AIDS cases as a result of vertical transmission.
