The reorganization of the Brazilian health system in the last few years has been based on the decentralization of the services and the integration of preventive and curative medicine, then creating new needs in term of the health information needed for health planning. The planning and administration of a regionalized and integrated health system calls for information about the population's morbidity profile, and the description of the pattern of the utilization of the health services, which can be obtained by means of household health surveys. The methodology utilized in a household health survey carried out in the Metropolitan Area of S. Paulo, Brazil, from July 1989 to June 1990, is described. This survey has some distinct methodological characteristics, such as the sampling process that defined the domains by age and sex, allowing an analysis of populational groups less well represented in the general population, as that of less than one year of age and that of aged people, as well as the use of the results of the latest Brazilian Census in 1991 for adjusting the sample.

The diagnostic categories of the patients discharged from the "Hospital das Clínicas" of the University of São Paulo in 1989 were arranged according the International Classification of Diseases (I.C.D.) and analysed. In each Group sex, age and the reason of discharge or death was indicated. The data concerning 39,601 cases were provided by the Medical Data Service of the "Instituto Central" of the "Hospital das Clínicas". Only the principal diagnosis was taken into account. In the "Instituto de Psiquiatria" most the patients (55.4%) were males between 20 and 49 years of age. The main diagnostic categories were affective psychoses (20.3%), schizophrenic disorders (15%), and disorders related to alcoholism (9.5%). The mortality rate was 0.27%. In the "Instituto da Criança" 56% of the patients that left the hospital were male children and 45.8% of them were less than one year old. Regarding to the diagnostic categories the most important one was that of the diseases of the respiratory system with 27.1% of cases, followed by that of infectious and parasitic diseases with 16.0% of cases. Within the respiratory diseases the most important were the pneumonias caused by not specified microorganisms, and within the infectious diseases the most important was the diarrhea of presumably infectious origin. The mortality rate in this Institute was 9.4%. The "Instituto de Ortopedia e Traumatologia" left 3,825 patients 61.7% males, and 46.9% of them were aged between 20 and 49 years.
