Optimizing discharge decision-making in colorectal surgery: a prospective cohort study of discharge practices in a...

The objectives of this project were (1) to compare time to readiness for discharge by set criteria and actual length of stay (LOS) in a newly implemented colorectal enhanced recovery pathway and (2) to identify reasons for delayed hospital discharge.

We conducted a prospective cohort study of 73 adult patients (age 67 ± 14 years, 56% men, 51% laparoscopic, 13% stoma creation) undergoing elective colorectal surgery in a university hospital with a recently implemented recovery pathway (<2 years). Time to readiness for discharge (oral intake, flatus, pain control, ability to walk, and no complications) was compared to actual LOS using a correlation-adjusted log-rank test. The treating team was interviewed, and thematic analysis was used to identify reasons for patients remaining in hospital after discharge criteria (DC) were achieved.

Median LOS was 6 (4-8) days and median time to readiness for discharge was 5 (3-8) days (P < 0.001). Twenty-eight patients (37%) remained in hospital after DC were achieved. Although some delayed discharges were medically justified (e.g., workup [13%] or treatment of complications not captured by DC [2.6%]), unnecessary hospital stays were common (e.g., perceived need for observation [16%], or patients not willing to be discharged [11%]).

Unnecessary hospital stays were common within a recently implemented enhanced recovery pathway and represent a target for quality improvement. Efforts should be directed at optimizing patient education regarding discharge expectations, early consultation of the discharge planning team and improving discharge decision-making using standardized DC.
