RESUMO
OBJECTIVES: The effect of a patient's Social Vulnerability Index (SVI) on complication rates after esophagectomy remains unstudied. The purpose of this study was to determine how social vulnerability influences morbidity following esophagectomy. METHODS: This was a retrospective review of a prospectively collected esophagectomy database at one academic institution, 2016 to 2022. Patients were grouped into low-SVI (<75%ile) and high-SVI (>75%ile) cohorts. The primary outcome was overall postoperative complication rate; secondary outcomes were rates of individual complications. Perioperative patient variables and postoperative complication rates were compared between the 2 groups. Multivariable logistic regression was used to control for covariates. RESULTS: Of 149 patients identified who underwent esophagectomy, 27 (18.1%) were in the high-SVI group. Patients with high SVI were more likely to be of Hispanic ethnicity (18.5% vs 4.9%, P = .029), but there were no other differences in perioperative characteristics between groups. Patients with high SVI were significantly more likely to develop a postoperative complication (66.7% vs 36.9%, P = .005) and had greater rates of postoperative pneumonia (25.9% vs 6.6%, P = .007), jejunal feeding-tube complications (14.8% vs 3.3%, P = .036), and unplanned intensive care unit readmission (29.6% vs 12.3%, P = .037). In addition, patients with high SVI had a longer postoperative hospital length of stay (13 vs 10 days, P = .017). There were no differences in mortality rates. These findings persisted on multivariable analysis. CONCLUSIONS: Patients with high SVI have greater rates of postoperative morbidity following esophagectomy. The effect of SVI on esophagectomy outcomes warrants further investigation and may prove useful in identifying populations that benefit from interventions to mitigate these complications.
