Acessibilidade e saúde: efeitos da pavimentação da rodovia 429 sobre atenção à saúde

Abstract

This work aims to examine the effect of paving the BR-429 highway on healthcare networks in the area within the Legal Amazon. Data about the highway were obtained from DNIT (National Department of Transport Infrastructure) and SNV (National Road System) to create a development timeline of the highway infrastructure being studied. Healthcare network data were collected through DataSUS and CNES (National Registry of Health Establishments). Therefore, a Diff-in-Diff model (difference in differences) was used to analyze how highway paving impacted access to treatments and vaccines provided by local health facilities near or intersected by BR-429. The surface improvements over the years have led to increased vaccination coverage in the region. This supports the idea that better highway infrastructure enhances population access to health services, especially in remote areas. The main limitation was the inability to analyze the highway connection to other roads, which could directly influence the results and potentially bias the importance of the section studied individually.
