Dr Mary Kwaan and colleagues described patterns and etiology of readmission, to determine the rate of readmission, and to identify risk factors for readmission after colorectal surgery.
The team performed a retrospective medical chart review in a tertiary care hospital.
The doctors analyzed 220 patients undergoing major colorectal operations by colorectal surgeons at the University of Minnesota in 2008–2009.
The primary outcome measure was hospital readmission at 60 days.
|Readmissions at 60 days occurred in 25%|
|Diseases of the Colon and Rectum|
Common surgical indications were inflammatory bowel disease, colorectal cancer, and diverticular disease, and were emergencies.
Readmissions at 60 days occurred in 25%, mostly because of major complications, nonspecific nausea, vomiting and/or pain, dehydration, and wound infections.
Predictors of readmission in multivariable analysis were major complications, female sex, prednisone use, BMI =30, and preoperative weight loss.
Age and comorbidity were not predictors.
Dr Kwaan's team commented, "Predictors of readmission were major complications and immediate preoperative condition of the patients."
"Comorbidity profiling does not capture readmission risk."
"Because most readmissions relate to complications, further efforts to prevent these will improve readmission rates."
