Abstract
e18386 Background: Advanced lung cancer (ALC) is a symptomatic disease that is often diagnosed in the context of hospitalization. The index hospitalization may be a window of opportunity to improve cancer care delivery. We aimed to define the frequency of ALC diagnosis associated with hospitalization and the relationship to subsequent cancer care and readmissions. Methods: We identified patients in the SEER-Medicare database with: ALC (stage IIIB-IV non-small cell or small cell), diagnosed 2007 to 2013; with continuous enrollment in Medicare from 6 months prior to lung cancer diagnosis through death or 12/2014; and an index hospitalization within 7 days of their ALC diagnosis. Our primary outcomes of interest were 30-day re-hospitalization and emergency department (ED) use. We examined: utilization of services during index hospitalization, including intensive care and oncology or palliative care consultation; discharge destination; receipt of systemic therapy; and hospice enrollment. Results: Fifty-four percent (n = 28,976) of ALC patients had an index hospitalization, with 90% of those having their cancer diagnosed while hospitalized. During their index hospitalization, 16% had oncology consultation, and 6% had palliative care (PC) consultation. Thirty-three percent were in the intensive care unit. At discharge, 59% returned home, 8% died, and 11% went to hospice. Of those who survived to discharge, 69% later returned to the ED or were re-hospitalized, with 49% of re-hospitalizations and 35% of ED visits occurring within 30 days of the index hospitalization. Thirty-five percent of these patients eventually received systemic treatment for their cancer. By 180 days post-discharge, 77% had enrolled in hospice with a median of 10 days on hospice care. Conclusions: Newly diagnosed ALC patients are high risk for acute care utilization, and many patients experience a return to the hospital early in their cancer trajectory. These patients may benefit from additional health system support prior to hospital discharge to help prevent high-cost, low-value healthcare utilization.
