Readmission Rates Similar for Prostate Surgery Techniques

In a Swedish study, 3 different RP approaches were associated with readmission.
In a Swedish study, 3 different RP approaches were associated with readmission.

A Swedish study of 24,122 prostate cancer (PCa) patients undergoing radical prostatectomy from 2000-2011 found that hospital readmission rates did not differ significantly by surgical approach.

A total of 2,317 patients (10%) required readmission in the 90 days after surgery. The readmission rates were 10% after retropubic radical prostatectomy (RRP), 9% after robotic-assisted laparoscopic prostatectomy (RALP), and 11% after laparoscopic radical prostatectomy (LRP), investigators reported online ahead of print in The Journal of Urology.

“With the exception of LRPs performed during 2000-2002, when it was first introduced, we found relatively small differences in readmission frequency between the three surgical methods,” the researchers, led by Jóon Örn Friðriksson,MD, of Umea University in Umea, Sweden, reported. “The high initial readmission rates for LRP were likely due to the learning curve.”

The study also showed that the number of RALPs during the study period, from no procedures in 2000-2002 to 50% of all RP's in 2009-2011.

Patients undergoing RP during 2009-2011 had a 29% decreased likelihood of readmission than those undergoing RP during 2000-2002, the investigators found. Patients aged 70 years and older were 17% more likely to be readmitted than those younger than 60 years. Patients with high-risk PCa were 78% more likely to be readmitted than those with low-risk PCa. Additionally, patients with a Charlson comorbidity index (CCI) of 3 or higher were 77% more likely to be readmitted those with a CCI of 0. Patients who underwent RP at high-volume hospitals (150 or more RPs per year) had a 30% decreased likelihood of readmission than those who underwent RP at low-volume hospitals (fewer than 30 RPs per year).
