Summary
This study looks at how social and economic factors—like income and neighborhood—affect recovery and survival after surgery. Researchers will study 45,000 patients in Brazil to see if those facing more hardship have worse outcomes. The goal is to identify vulnerable patients and help reduce unfair differences in surgical care.
