Introduction
Readmissions after radical cystectomy are common. Details regarding readmissions after robotic surgery are limited to institutional series. To inform whether readmission reduction strategies should consider surgical approach, we examined readmission differences between open and robotic-assisted radical cystectomy (RARC) using population-based data.
Methods
We identified patients who underwent cystectomy between January 2010 and September 2013 based on ICD-9 codes and administrative claims from a large, national US health insurer (Clinformatics™ Data Mart Database, OptumInsight, Eden Prairie, MN). We assessed post-discharge health system utilization and tested for differences in readmissions after the two surgical approaches.
Results
We identified 935 patients treated with cystectomy (785 (84%) open, 150 (16%) RARC). Patients undergoing RARC were slightly older, male, had more ileal conduit urinary reconstruction, and less need for intensive care. Index length of stay was shorter for RARC than for open surgery (7 days vs. 8 days, p<0.001). However, we found no differences in 30-day readmission rates (24% open vs. 29% RARC, p=0.26) or other readmission parameters including: readmission length of stay (5 days open vs. 4 days RARC, p=0.32), emergency department use (22% open vs. 24% RARC, p=0.86), reasons for readmission, or timing of first outpatient visits (11.5 days open vs. 9 days RARC, p=0.41). For both approaches, the majority of patients were readmitted within 2 weeks.
Conclusions
The surgical approach to cystectomy does not appear to impact readmissions. Strategies to reduce the readmission burden after cystectomy do not need to consider surgical approach, but should focus on timing of medical contacts
