Surgical center for ambulatory extended recovery: 30-day follow-up report of minimally invasive radical prostatectomy.

83 Background: In January 2016, we opened a novel, multidisciplinary ambulatory surgical center dedicated to perform complex cancer surgeries on an Ambulatory Extended Recovery (AXR) pathway specifically aimed at a 1-night or less hospital stay. This is a standalone facility separate from the inpatient hospital. The aim of this study is to evaluate the 30-day post-operative follow-up of Minimally Invasive Radical Prostatectomy (MIRP) performed in an ambulatory care setting. Methods: Between January 2016 – September 2016, we performed 424 MIRP in the AXR dedicated surgical center. The baseline demographics, cancer characteristics, surgical information and follow-up data were prospectively collected. We evaluated the 30-day complications, rate of falling-off the AXR pathway, rate of transfer to our inpatient hospital, number urgent care visits and need for re-admission. Results: MIRP was performed as robot assisted (85%) and laparoscopic (15%) procedures. The median (range) overall length of hospital stay was 27.1 (11.4 – 35.2) hours with a total operative time of 4.8 (3.1 – 9.3) hours with an estimated blood loss of 175 (20 - 800) ml. Nine patients (2.1%) fell off the AXR pathway and were transferred to the main hospital for further care. In the 30-day post-surgery period, complications were noted in 6.4% patients (Grade 1 -38%, 2 - 34% 3 – 27%), while urgent care visits and re-admission rates were 10.7% and 2.6% respectively. The median (range) time from surgery to re-admission was 16 (2 - 43) days. Conclusions: A multidisciplinary ambulatory surgical center with a dedicated AXR pathway represents a significant advancement in MIRP surgical care, providing a 1-night hospital stay in an ambulatory setting with acceptably low rates of complications, urgency care visits and re-admissions.
