Study of public and private hospital care on a populational basis, 1986-1996

Introduction The last decade saw the creation and implementation of the Brazilian National Health System (NHS) - public, universal and equalitarian - with the objective of offering wide coverage to meet the population's health needs. The objective of the study was the assessment of the evolution of public and private hospital care on a populational basis during the period of the implementation of the NHS. Methods The 984, 142 inpatients of the general hospitals of Ribeirao Preto, Brazil, during the period 1986 to 1996 were studied and those of them living in their own municipal district were selected. The inpatients are classified according to the financing system as private, pre-payment and NHS; the social situation of the patients and the profile of hospital morbidity are analysed. Results In the period studied a continuous growth in the number of hospitalizations is observed both in absolute numbers and in coefficient per thousand inhabitants, increasing from 43, 773 to 55,844 inpatients per year Though when the categories of the hospitalizations are studied, it is seen that private inpatients present a reduction both in absolute numbers and as a coefficient from 3,181 (7.3%) to 2,215 (3.9%); the NHS inpatients decrease in absolute numbers and in a percentage by a third at the end of the period - falling from 33,254 (76.0%) to 29,373 (51.7%). On the other hand the pre-payment inpatient system triplicates in absolute numbers and duplicates by rate for inhabitant - from 7,338 (16.8%) to 25,256 (44.4%). The NHS hospital care attends mainly unskilled and semi-skilled manual workers; the professionals, technicians, non manual and skilled manual workers being assisted by the private services. The hospital morbidity of NHS inpatients is different from that of the private inpatient systems. The health policy in that period, limiting NHS financing, repressing demand and discouraging the private providers to work with NHS inpatients led to negative selectivity. The result was an increase in difference between standards of care as between the public and private services.
