Is this trial a fit for you?
✓Likely a good fit
Adults aged 16 and older who had elective or urgent surgery in a participating Brazilian hospital during 2024.
✕Probably not a fit
Patients undergoing procedures excluded by eligibility (ophthalmologic, diagnostic-only, local anesthesia, or certain organ transplants) or those treated in non-participating sites may not experience any identified benefit from the study.

What this trial studies
This is a retrospective, multicenter observational cohort study using routinely collected hospital data from 2024. It will examine whether area-level socioeconomic deprivation, derived from patients' residential addresses, is associated with perioperative outcomes after elective or urgent surgery. Participating centers span public and private hospitals across multiple regions in Brazil, and no changes to clinical care will be made for the study. The analysis will adjust for patient and hospital factors to understand the potential impact of social deprivation on outcomes such as recovery and complications. The study aims to fill gaps in knowledge about socioeconomic influences on surgical care in a middle-income country context.
Why it matters
Potential benefit: If associations are found, findings could inform policies and practices to reduce inequities in surgical outcomes related to social factors.
How similar studies have gone: Previous work suggests socioeconomic factors influence surgical outcomes in some settings, but data from Brazil and across diverse procedures remain limited; this study builds on that groundwork in a broader national context.
