Background: Limited data are available on the incidence, risk factors, and causes of 30-day readmissions in patients hospitalized with critical limb ischemia (CLI).
Methods: Patients with CLI who underwent endovascular and/or surgical therapy and who were discharged alive between January and November 2013 were identified in the Nationwide Readmissions Database. Incidence and causes of 30-day readmissions were determined. Hierarchical, mixed-effects models were used to identify independent predictors of 30-day readmissions.
Results: Of 29,869 (national estimate = 67,664) patients with CLI (mean age 69.1 ± 11.9 years; 41.5% women; 25.2% with rest pain, 37.3% with ulcer, and 37.4% with gangrene), 5,810 (19.5%) were readmitted within 30-days. Median time to readmission was 12 (IQR: 6-20) days. Independent predictors of 30-day readmission are shown in Figure 1. Neither CLI presentation nor mode of revascularization was independently associated with readmission. The most common reasons for 30-day readmissions were infection (25.1%), peripheral artery disease (18.9%), cardiac (11.3%), and non-healing wound (6.1%). Median length of stay for 30-day readmission was 5 (IQR: 3-9) days and in-hospital mortality was 5.0%.
Conclusions: Approximately 1 in every 5 patients with CLI is readmitted within 30-days. Risk of readmission is influenced by patient demographics and comorbidities, but not by CLI presentation nor by mode of revascularization.
