Early Discharge After Radical Nephrectomy: An Analysis of Complications and Readmissions.

INTRODUCTION

Length of stay (LOS) is increasingly being viewed as a quality metric, and efforts to reduce LOS are present across most surgical subspecialties. However, data on whether reducing LOS is safe in patients who undergo radical nephrectomy (RN) are lacking. The purpose of this study was to assess whether early discharge after RN affects readmission rates and postdischarge complications using a national cohort of patients.

PATIENTS AND METHODS

The American College of Surgeons National Surgical Quality Improvement Program database was used to identify patients who underwent RN from 2012 to 2015. Procedures were stratified as minimally invasive or open. Early discharge was defined as less than or equal to the procedure-specific 25th percentile for LOS. Multivariable analysis was used to identify factors associated with readmission and postdischarge complications. A sensitivity analysis excluded patients with a LOS >75th percentile.

RESULTS

A total of 11,429 patients were included. The 25th percentile for LOS was 2 days in the minimally invasive group and 3 days in the open group. In multivariable analysis, early discharge did not increase the risk of postdischarge complications (odds ratio, 0.88; 95% confidence interval, 0.71-1.08; P = .214) and decreased the risk of readmission (odds ratio, 0.72; 95% confidence interval, 0.59-0.87; P = .001).

CONCLUSION

Early discharge after RN does not increase the risk of postdischarge complications or readmission. With the appropriate patient selection, decreasing LOS might lead to decreased surgical costs and improved patient flow. This work provides a foundation for future research that might optimize perioperative care pathways to decrease LOS.
