Importance: Cellulitis commonly results in hospitalization. Limited data on the proportion of cellulitis admissions associated with readmission are available.
Objective: To characterize the US national readmission rate associated with hospitalization for treatment of cellulitis.
Design, Setting, and Participants: This retrospective cohort analysis of cellulitis admissions from the nationally representative 2014 Nationwide Readmissions Database calculated readmission rates for all cellulitis admissions and subsets of admissions. The multicenter population-based cohort included adult patients admitted for conditions other than obstetrical or newborn care. Data were collected from January 1 through November 30, 2014, and analyzed from February 1 through September 18, 2018. Bivariate logistic regression models were used to assess differences in readmission rates by patient characteristics. Costs were calculated for all readmissions after discharge from hospitalization for cellulitis (hereinafter referred to as cellulitis discharge) and by readmission diagnosis.
Exposures: Admission with a primary diagnosis of cellulitis.
Main Outcomes and Measures: Proportion of cellulitis admissions associated with nonelective readmission within 30 days, characteristics of patients readmitted after cellulitis discharge, and costs associated with cellulitis readmission.
Results: A total of 447 080 (95% CI, 429 927-464 233) index admissions with a primary diagnosis of cellulitis (53.8% male [95% CI, 53.5%-54.2%]; mean [SD] age, 56.1 [18.9] years) were included. Overall 30-day all-cause nonelective readmission rate after cellulitis discharge was 9.8% (95% CI, 9.6%-10.0%). Among patients with cellulitis, age (odds ratio for 45-64 years, 0.78; 95% CI, 0.75-0.81; P = .001) and insurance status (odds ratio for Medicare, 2.45; 95% CI, 2.33-2.58; P < .001) were associated with increased readmission rates. The most common diagnosis of readmissions included skin and subcutaneous tissue infections. The total cost associated with nonelective readmissions attributed to skin and subcutaneous infections within 30 days of a cellulitis discharge during the study period was $114.4 million (95% CI, $106.8-$122.0 million).
Conclusions and Relevance: Readmission after hospitalization for cellulitis is common and costly and may be preventable with improved diagnostics, therapeutics, and discharge care coordination.
