Rehabilitation after brain tumor resection: A national study of postacute care service use through insurance claims data.

Abstract

To assess postacute rehabilitation service use and length of stay among a national sample of patients with brain tumors after surgery. A retrospective review was conducted of health care claims data of a national sample of patients via The Optum Clinformatics DataMart. This study included adult individuals (≥18 years of age) who were diagnosed with a brain tumor between 2015 and 2019 and underwent a craniotomy or craniectomy within 180 days of diagnosis. Descriptive statistics were used to characterize patients by tumor type. Multivariate models assessed factors associated with discharge setting and length of stay. Of the 10,275 individuals identified, 69% had malignant tumors. Over two thirds of patients were discharged directly home (with or without home health care) and 9.3% and 9.5% were discharged to acute rehabilitation facilities (inpatient rehabilitation facilities [IRF]) and skilled nursing facilities (SNF/ICF), respectively. About 13.5% were discharged to other settings. The average length of stay during the episode of care was 8.6 (SD = 9.6) days. After adjusting for confounders, individuals with benign brain tumors were more likely to be discharged to either IRF or SNF/ICF than return home after acute care stay, as were those with greater comorbidities, older age, fee-for-service and health maintenance organization insurance. Wealthier patients were less likely to be discharged to a SNF/ICF than home, although income was not a factor affecting discharge to an IRF. Patients with benign tumors, the oldest old (80+), those with more comorbidities as well as Black and Hispanic patients had a longer length of stay during the acute hospitalization. Individuals with brain tumors have deficits amenable to rehabilitation; however, this study finds that service use differs by tumor type and demographic and socioeconomic factors. Further study is needed to identify if there are barriers to access and use of rehabilitation services in this population.
