Geospatial Analysis of Accessibility to Surgical Care, a Brazilian Local Perspective

Background Surgical care has been neglected and recently discussed by the World Health Organization as a necessary component of health care. Situations that distance individuals and medical services are of particular concern. We aim to estimate the distance a patient who lives in a municipality without a general surgeon would have to travel to access surgical care; and to describe the geographical distribution of the surgical workforce. Methods We obtained the surgical data from DATASUS, from IBGE, the information regarding the classification of each municipality and its location, and FEPAM, the road network. We performed the geoprocessing analysis on QGIS and the statistical analysis on SPSS. Results The Rio Grande do Sul state had 496 municipalities, of which 69.4% were rural, with a mean of 9.19 general surgeons per overall municipality. A total of 237 cities had no general surgeons, of which 89.45% were in rural ones. There was a significant difference in the number of surgeons per municipality between rural and urban ones. We found a mean of 22.09 surgeons per 100,000 population. The mean distance traveled by a patient to a municipality with general surgeons available was 30.25 km, with a minimum of 2.46 km and a maximum of 268.22 km. Conclusions Disparities are associated with the geospatial distribution of surgical care in the Rio Grande do Sul state. The surgical workforce and the distance a patient travels are irregular geographically. This study is the start of inspiring other similar studies about geospatial surgical analysis.
