The Socioeconomic Distressed Communities Index Predicts 90-Day Mortality Among Intracranial Tumor Patients.

Socioeconomic status (SES) is a major determinant of quality of life and outcomes. However, SES remains difficult to measure comprehensively. Distress communities index (DCI), a composite of 7 socioeconomic factors, has been increasingly recognized for its correlation with poor outcomes. As a result, the objective of the present study is to determine the predictive value of the DCI on outcomes following intracranial tumor surgery. A single institution, retrospective review was conducted to identify adult intracranial tumor patients undergoing resection (2016–2021). Patient ZIP codes were matched to DCI and stratified by DCI quartiles (low:0–24.9, low-intermediate:25–49.9, intermediate-high:50–74.9, high:75–100). Univariate followed by multivariate regressions assessed the effects of DCI on postoperative outcomes. Receiver operating curves were generated for significant outcomes. A total of 2389 patients were included: 1015 patients (42.5%) resided in low distress communities, 689 (28.8%) in low-intermediate distress communities, 445 (18.6%) in intermediate-high distress communities, and 240 (10.0%) in high distress communities. On multivariate analysis, risk of fracture (adjusted odds ratio = 1.60, 95% confidence interval 1.26–2.05, P < 0.001) and 90-day mortality (adjusted odds ratio = 1.58, 95% confidence interval 1.21–2.06, P < 0.001) increased with increasing DCI quartile. Good predictive accuracy was observed for both models, with receiver operating curves of 0.746 (95% CI 0.720–0.766) for fracture and 0.743 (95% CI 0.714–0.772) for 90-day mortality. Intracranial tumor patients from distressed communities are at increased risk for adverse events and death in the postoperative period. DCI may be a useful, holistic measure of SES that can help risk stratifying patients and should be considered when building healthcare pathways. [ABSTRACT FROM AUTHOR]
