Abstract
Background
Health expenditures have become a global concern given the scarcity of financial resources to meet health demands.
Objective
To analyze the trend of per capita expenditure with high-complexity diagnostic imaging and its association with sociodemographic and structural variables in Brazil.
Method
Observational, ecological study on diagnostic imaging expenditures using the Unified Health System (SUS) information system records, through regression analysis with Generalized Mixed Effects Models, from 2008 to 2017, by health macro-regions, according to the following variables: GDP per capita, population, rate of physicians, rate of equipment in use at SUS, and coverage by the Family Health Strategy (FHS).
Results
Descriptive analysis of the data showed an increase in expenses with high-complexity diagnostic imaging. Expenditure was positively correlated with rate of physicians, rate of equipment in use in SUS and GDP per capita, and negatively correlated with FHS coverage.
Conclusion
The relationship between expansion of coverage by the FHS and decreased expenses with high-complexity diagnostic imaging was an important indicator to direct public policies and allocate resources. Thus, macro-regions with higher GDP per capita and rate of physicians tend to have greater expenses with high-complexity diagnostic imaging.
