Primary payer status, individual patient characteristics, and hospital-level factors affecting length of stay and total cost of hospitalization in total laryngectomy.

Abstract

Medicaid and uninsured patients anecdotally incur higher cost and length of stay because of nonmedical, discharge-related factors. The purpose of this study was to investigate the association between primary payer and length of stay and cost, controlling for comorbidities and complications, in patients undergoing total laryngectomy. The sample included 4128 patients who underwent total laryngectomy in the 2005 to 2010 National Inpatient Sample (NIS). Patients were categorized into 4 subgroups based on payer status: Medicare, Medicaid, uninsured, and private insurance. Using multilevel modeling, we examined differences in length of stay and hospitalization costs. The odds of being in the top quartile of length of stay increased for Medicaid patients by 41% (odds ratio [OR] = 1.41; 95% confidence interval [CI] = 1.03-1.92) compared with privately insured patients. After controlling for medical factors, Medicaid patients had increased lengths of stay. Overall costs were highest for those with public insurance, but no difference was seen for the adjusted cost. © 2016 Wiley Periodicals, Inc. Head Neck 39: 311-319, 2017.
