Key result
Smoking, diabetes, and missed follow-up linked to ~2-fold higher 30-day post-colectomy readmission.
Why the study?
Hospital readmissions after colorectal surgery remain a major medical and financial concern, and there is a need to identify process measures to reduce readmissions.
What are the patient characteristics and surgical factors associated with 30-day readmissions for colorectal surgery?
Cohort (n=630)
Yes
What are the patient characteristics and surgical factors associated with 30-day readmissions for colorectal surgery?
Diabetes, smoking, lack of scheduled follow-up, and ileostomy formation are independent risk factors for 30-day readmission after colectomy, providing tangible targets for intervention.
Identifies diabetes, smoking, no follow-up, and ileostomy as readmission risks after colectomy; hypothesis-generating and requires prospective validation before guiding practice.
BACKGROUND: Hospital readmissions remain a major medical and financial concern to the healthcare system and have become an area of interest in health outcomes performance metrics. There is a pressing need to identify process measures that may help reduce readmissions. OBJECTIVE: Our aim was to assess the patient characteristics and surgical factors associated with 30-day readmissions for colorectal surgery in Upstate New York. DESIGN: This was a retrospective cohort study. SETTINGS: The study included colectomy cases abstracted for the National Surgical Quality Improvement Program in the Upstate New York Surgical Quality Initiative from June 2013 to June 2014. PATIENTS: The study consists of 630 colectomies. Patients with a length of stay >30 days or who died during the index admission were excluded. MAIN OUTCOME MEASURES: Readmission within 30 days of surgery was the main outcome measure. RESULTS: Of 630 colectomy patients, 76 patients (12%) were readmitted within 30 days of surgery. Major and minor complications were associated with 30-day postoperative readmission (OR = 2.99 (95% CI, 1.70-5.28) and OR = 2.19 (95% CI, 1.09-4.43)) but excluded from final analysis because they included both predischarge and postdischarge complications. Risk factors independently associated with 30-day postoperative readmission included diabetes mellitus (OR = 1.94 (95% CI, 1.02-3.67)), smoker within the past year (OR = 2.01 (95% CI, 1.12-3.60)), no scheduled follow-up (OR = 2.20 (95% CI, 1.25-3.86)), and ileostomy formation (OR = 1.97 (95% CI, 1.03-3.77)). LIMITATIONS: Limitations include the retrospective design and only 30 days of postoperative follow-up. CONCLUSIONS: Consistent with national trends, 1 in 8 patients in the Upstate New York Surgical Quality Initiative program was readmitted within 30 days after colorectal surgery. This study identified several risk factors that may act as tangible targets for intervention, including preoperative smoking cessation programs, optimization of diabetic management, mandatory scheduled follow-up appointments on discharge, and ostomy care pathways.

Hensley et al. (2016) conducted a cohort in Colectomy (n=630). Risk factors (diabetes mellitus, smoking, no scheduled follow-up, ileostomy formation) vs. Absence of risk factors was evaluated on Readmission within 30 days of surgery. Diabetes (OR 1.94), smoking (OR 2.01), no scheduled follow-up (OR 2.20), and ileostomy (OR 1.97) were independently associated with 30-day readmission, which occurred in 12% of 630 colectomy patients.
