Secemsky EA, et al. - An inquiry was set up with regard to the nationwide readmissions after peripheral arterial revascularization for peripheral arterial disease. The authors also analyzed if variation existed in the readmission risk among hospitals. Unplanned readmission within 30 days was reported in more than 1 in 6 patients with peripheral arterial disease who underwent peripheral arterial revascularization, exhibiting high associated mortality risks and costs. The primary reasons for readmission were disclosed to be procedure-and patient-related factors. Moderate variation was found in the readmission rates between institutions after hospital case mix was accounted for. This data indicated that differences in hospital quality could only partially account for readmission.

Methods

• The plot of this research was a retrospective cohort study.
• A total of 1,085 U.S. acute care hospitals took part in the Nationwide Readmissions Database.
• The enrollment consisted of 61,969 patients with peripheral arterial disease who had peripheral arterial revascularization and were discharged alive between 1 January and 30 November 2014.
• The measurements to be estimated included 30-day readmission rates, causes, and costs of unplanned rehospitalizations after peripheral arterial revascularization; 30-day risk-standardized readmission rates (RSRRs), computed via hierarchical logistic regression.
• The purpose was to investigate for the heterogeneity of readmission risk between hospitals.

Results

• The 30-day nonelective readmission rate was discovered to be 17.6%, among 61,969 hospitalizations of patients with peripheral arterial disease who were discharged alive after peripheral arterial revascularization.
• Procedural complications (28.0%) served as the most common cause of readmission, followed by sepsis (8.3%) and complications due to diabetes mellitus (7.5%).
• It was reported that 21.0% patients underwent a subsequent peripheral arterial revascularization or lower extremity amputation, 4.6% died, among rehospitalized patients.
• The median cost of a readmission was $11,013.
• A variation was disclosed in the 30-day RSRRs from 10.0% to 27.3% (interquartile range, 16.6% to 18.8%).
