Longer hospital length of stay and pre-discharge complications increase the risk of hospital readmission within 30 days among patients who undergo robot-assisted radical prostatectomy (RARP), investigators reported at the 2017 congress of the European Association of Urology in London.

For each 1 day spent in the hospital, the relative risk of readmission and post-discharge complications increased by a statistically significant 35% and 16%, respectively, according to a poster presentation by a team from the University of Pennsylvania Perelman School of Medicine in Philadelphia led by Thomas Guzzo, MD, MPH. Compared with patients who had no pre-discharge complications, those who did had a statistically significant 2.2-fold increased relative risk of readmission, but not an increased risk of post-discharge complications.

The study cohort included 9975 RARP patients with a median age of 62 years (range 57-67 years). All were admitted from and discharged to home. Within 30 days post-discharge, 332 patients (3.3%) were readmitted and complications developed in 441 patients (4.4%).
