Abstract

Objectives

To identify the diseases that lead older persons to hospitalizations in the public health system in the state of Rio de Janeiro and, through a study of spatial distribution among hospitalization rates of the municipal districts, discuss the social contexts involved in the hospitalization of the elderly.

Methods

An ecological cross-sectional study using secondary data from the Brazilian hospital information system from the period 2009 to 2015 was performed. The hospitalization rates of people 60 years and older, residing in 92 municipalities in the state of Rio de Janeiro, were calculated. The municipal districts were grouped according to the similarity of such rates using K-means nonhierarchical clustering analysis.

Results

Diseases of the circulatory and respiratory systems, endocrine disorders, illnesses of the genitourinary system or the digestive tract, and certain infectious and parasitic diseases were the most discriminatory diseases for cluster composition. The first cluster, the municipal districts with the lowest hospitalization rates, which were more urbanized and had greater access to social and health services, was named Access and Inclusion. The second group, which had the highest hospitalization rates, was named Isolation and Vulnerability.

Conclusions

The primary care–sensitive conditions are the main causes of hospitalization of the elderly in the state, with greater intensity in the municipalities that are geographically rugged and remote. These outcomes reinforce the importance of valuing geographical knowledge, the guidelines of the unified health system concerning equity and regionalization, and the determinants and social determinations involved in the process of health and disease.
