ImportanceThirty-day hospital readmissions have substantial direct costs and are increasingly used as a measure of quality care. However, data regarding the risk factors and reasons for readmissions in head and neck cancer surgery reconstruction are lacking.ObjectiveTo describe the rate, risk factors, and causes of 30-day readmission in patients with head and neck cancer following free or pedicled flap reconstruction.Design, Setting, And ParticipantsThis retrospective, population-based cohort study analyzed medical records from the Nationwide Readmissions Database of 9487 patients undergoing pedicled or free flap reconstruction of head and neck oncologic defects between January 1, 2010, and December 31, 2014. Data analysis was performed in October 2017.ExposuresPedicled or free flap reconstruction of an oncologic head and neck defect.Main Outcomes And MeasuresThe primary outcome was 30-day all-cause readmissions. Secondary outcomes included risk factors, causes, and costs of readmission. Multivariate regression analyses were conducted to determine factors independently associated with 30-day readmissions.ResultsAmong 9487 patients included in the study (6798 male; 71.7%), the median age was 63 years (interquartile range, 55-71 years), and the 30-day readmission rate was 19.4% (n = 1839), with a mean cost per readmission of $15 916 (standard error of the mean, $785). The most common indication for readmission was wound complication (26.5%, n = 487). On multivariate regression, significant risk factors for 30-day readmission were median household income in the lowest quartile (vs highest quartile: odds ratio [OR], 1.58; 95% CI, 1.18-2.11), congestive heart failure (OR, 1.68; 95% CI, 1.14-2.47), liver disease (OR, 2.02; 95% CI, 1.22- 3.33), total laryngectomy (OR, 1.40; 95% CI, 1.12-1.75), pharyngectomy (OR, 1.47; 95% CI, 1.08-2.01), blood transfusion (OR, 1.30; 95% CI, 1.04-1.64), discharge to home with home health care (vs routine: OR, 1.32; 95% CI, 1.04-1.67), and discharge to a nursing facility (vs routine: OR, 1.77; 95% CI, 1.30-2.40).Conclusions And RelevanceUsing the Nationwide Readmissions Database, we demonstrate that approximately 1 in 5 patients undergoing head and neck cancer surgery reconstruction is readmitted within 30 days of surgery. Readmissions are most commonly associated with wound complications. Socioeconomic status, complex ablative procedures, and patient comorbidities are independent risk factors for readmission. These findings may be useful to clinicians in developing perioperative interventions aimed to reduce hospital readmissions and improve quality of patient care.
