Predictors of 30-day readmission in Stevens-Johnson syndrome and toxic epidermal necrolysis: A cross-sectional database study

Background: The predictors of readmission in Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) have not been characterized. Objective: To determine the variables predictive of 30-day readmission after SJS/TEN hospitalization. Methods: We performed a cross-sectional study of the 2010-2014 Nationwide Readmissions Database. Bivariate and multivariable logistic regression was used to evaluate associations of patient demographics, comorbidities, and hospital characteristics with readmission. Aggregate and per-readmission costs were calculated. Results: There were 8837 index admissions with SJS/TEN reported; of these, 910 (10.3%) were readmitted, with diagnoses including systemic infection (22.0%), SJS/TEN (20.6%), and cutaneous infection (9.1%). Associated characteristics included age 45 to 64 years (odds ratio [OR], 1.88; 95% confidence interval [CI], 1.43-2.49), Medicaid insurance (OR, 1.83; 95% CI, 1.48-2.27), and nonmetropolitan hospital admission (OR, 1.67; 95% CI, 1.31-2.13). Associated comorbidities included HIV/AIDS (OR, 2.48; 95% CI, 1.63-3.75), collagen vascular disease (OR, 2.38; 95% CI, 1.88-3.00), and metastatic cancer (OR, 2.16; 95% CI, 1.35-3.46). The median per-readmission cost was $10,019 (interquartile range, $4,788-$16,485). Limitations: The Nationwide Readmissions Database lacks the ability to track the same patient across calendar years. The diagnostic code lacks specificity for hospitalizations <3 days. Conclusions: Thirty-day readmissions after SJS/TEN hospitalizations are common. Dedicated efforts to identify at-risk patients may improve peridischarge continuity.
