Readmission and Adoption of Early Discharge After Colectomy Using ACS-NSQIP: Is It Time for Widespread Adoption?

Introduction: The timing of post-operative discharge following colectomy procedures remains a subject of debate among colorectal surgeons. Prior studies have demonstrated the safety and adoption of early discharge within 24 h after elective colectomy in carefully selected patients.

Methods: This retrospective cohort study utilizing data from the American COllege of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) from 2012 to 2021. Adult patients undergoing elective partial colectomy with primary anastomosis and documented length of stay were included. Patients were stratified into early (< 24) and non early (≥24 h) discharge groups. Propensity score matching was used to control for baseline demographics and non-modifiable risk factors. Primary outcomes included 30-day readmission rates and adoption trends of early discharge over time.

Results: A total of 282,037 patients met inclusion criteria of which 6364 (2.3%) were discharged within 24 h. On propensity score matching the early discharge cohort had a statistically significantly lower rate of readmission (5.5% versus 7.3%, P < 0.001). Additionally, the early discharge group had a significantly reduced rate of anastomotic leak (1.0 versus 2.6%), ileus (2.0% versus 7.6%), and rate of reoperation (1.2% versus 4.0%) (P < 0.001). The proportion of early discharge colectomies increased from 0.8% in 2012 to 3.6% in 2021 (P < 0.001).

Conclusions: In carefully selected patients, early discharge after colectomy with primary anastomosis does not increase the risk of readmission, reoperation, or 30-d complication rates. Furthermore, the increasing trend in utilization of early discharge after colectomy suggests an increasing acceptance of this practice, though it remains a minority of all colectomies performed among institutions participating in ACS-NSQIP.
