Early Versus Delayed Urinary Catheter Removal After Minimally Invasive Lumbar Spine Surgery (EDUCaRe)

Early Versus Delayed Urinary Catheter Removal After Minimally Invasive Lumbar Spine Surgery: A Randomized-Controlled Clinical Trial

The study aims to compare between early versus delayed urinary catheter removal the impact on time to ambulation (in minutes) after minimally invasive lumbar spine surgery

Study Overview

Status

Withdrawn

Detailed Description

Early ambulation enables rapid removal of drainage tubes and canisters and decreases length of hospitalization. Previous article showed that a 1-day shorter in hospitalization led to an approximately US$ 2000 reduction in total patient costs. Another study examining patients after total knee arthroplasty found that an early discharge group, a decrease in length of stay in 22h resulted in financial savings of approximately US$ 600 per case.

Another author found that early ambulation was associated with 19% lower 90-day readmission rate. Moreover, early ambulation contributed to 50.6% lower probability of developing at least one complication than regular ambulation.
