[Contribution of hospitalizations for primary care-sensitive conditions to the profile of admissions in the public health care system].

Objective: To describe the epidemiological profile of hospitalizations in the city of Divinópolis, state of Minas Gerais, Brazil, to estimate the prevalence of hospitalizations for primary care-sensitive conditions (HPCSC), and to evaluate the factors associated with the occurrence of HPCSC.

Methods: A cross-sectional study was conducted of the two public health care institutions in Divinópolis qualified to hospitalize individuals; that is, a general hospital and an urgent care unit. The data were collected between July and October 2011. Admissions were screened based on information available through the state of Minas Gerais data exchange software SUS Fácil, hospital admission authorizations, and patient records. Descriptive analyses were carried out, with estimation of the prevalence of admissions according to the groups of the 10th revision of the International Classification of Diseases (ICD-10). The identification and classification of HPCSC was based on the Brazilian List of primary-care sensitive conditions published by the Ministry of Health. The strength of the association between HPCSC and selected variables was estimated based on the prevalence ratio.

Results: Two thousand seven hundred seventy five admissions were identified. The main causes were neoplasms (18%), diseases of the circulatory system (16%), pregnancy and childbirth (15%), and external causes (12%). The prevalence of HPCSC was 36.6%, with the main diagnoses being diseases of the circulatory and respiratory systems. One third of the admissions occurred through the urgent care unit, which was also responsible for more than half of the HPCSC. Female sex, age younger than 13 years and older than 40 years, and living in Divinópolis were associated with higher chance of admission due to HPCSC (P < 0.01).

Conclusions: The results show a high prevalence of HPCSC, especially through the urgent care unit. This indicates an overburdening of urgent care services, hindering the implementation of a longitudinal continuum of care at the primary level.
