Purpose: Lung cancer patients experience functional deconditioning secondary to their underlying cancer and treatment yet rehabilitation service use remains low. The goal of this study is to compare post-acute care service use in lung cancer patients admitted to a metropolitan academic medical center. Methods: Adult lung cancer patients admitted from January 1, 2017 to August 31, 2018 with a diagnosis of lung cancer based on International Classification of Diseases 10, C34.0-C34.9, were included in this study. Patient characteristics including age, gender, race, marital status, functional status on admission, length of stay, and number of comorbidities were compared based on discharge setting. Results: 1,139 lung cancer patients were included in our study. The majority of patients discharged home with home care (51%) followed by home without services (35%), skilled nursing facilities (SNF) (10%) and acute inpatient rehabilitation facilities (IRF) (4%). 44% (498) of patients were primarily admitted for their lung cancer diagnosis. In unadjusted analyses, patients who discharged to SNF compared to home were more likely to be older, black, unmarried, live alone and have died during the study period. Patients who discharged to IRF had longer acute care hospitalization length of stays. In adjusted analyses, age, number of concurrent comorbidities and length of stay significantly correlated with discharge location. Conclusion: Lung cancer patients are unlikely to be discharged to a post-acute care facility after an acute hospitalization. Rehabilitation service use differs by sociodemographic factors, concurrent medical history and functional status. Future study is needed to better understand why these differences in discharge setting persists.
