Factors Associated With Head and Neck Cancer Hospitalization Cost and Length of Stay—A National Study

Objectives: The aim of the study was to estimate hospitalization cost, and factors associated with hospitalization costs and length of stay (LOS) of patients treated for head and neck cancer in the United States. Methods: Data on 71,440 weighted hospital admissions from the 2014 National Inpatient Sample with a diagnosis of head and neck cancer were examined. Multivariable linear regression models estimated factors associated with hospitalization costs, and negative binomial regression models were used to identify factors associated with hospital LOS. Factor variables included characteristics of the patient, clinical, and hospital characteristics. Results: The average hospitalization cost was US $18,371 and the average LOS was 6.6 days. LOS was significantly associated with admissions involving bacterial infection, major operating procedures, chemo procedure, and radiation procedure as well as admissions at medium or small bed size hospitals, and rural hospitals. Admissions among black patients, elective admissions, admissions involving bacterial infection, major operating procedures, chemo procedure, radiation procedure, and advance comorbidities were associated with increased hospitalization costs. In contrast, admissions at urban nonteaching or rural had increased hospitalization costs. Conclusions: Admissions that involve higher number of comorbidities, metastasis, bacterial infection, radiation, and chemo procedures had longer hospital stay and higher cost whereas admissions are rural hospitals had shorter hospital stay and lower cost. Understanding these factors associated with increased LOS and hospitalization cost will help efforts to decrease health care cost and improve quality of care.
