      Background

      Little is known about the extent to which dying patients with lung cancer receive life-sustaining treatments and palliative care services at the end-of-life in U.S. hospitals. We examine hospital cost trends and the impact of palliative care utilization on the use of life-sustaining procedures in this population.

      Retrospective nationwide cohort analysiswas performed using National Inpatient Sample (NIS) data from 2005 and 2014. We examined the receipt of both palliative care and life-sustaining procedures, defined as systemic procedures, local procedures, or surgeries using the International Classification of Diseases, 9th revision (ICD-9-CM).

      We used compound annual growth rates (CAGR) to determine temporal trends and multilevel multivariate regressions to identify factors associated with hospital cost. Among 77,394,755 hospitalizations, 120,144 patients were examined. During 10 years, the CAGR of hospital cost was 7.05% (p<.0001). In contrast, the CAGR of hospital lengths of stay was -3.77% (p<.0001). The CAGRs of palliative care was over ten percentage (13.30 %, p<.0001). However, the CAGRs of systemic procedures, local procedures, and surgeries were less than around one percentage (-1.13%, -1.07% and 1.42%, each p<.0001). Systemic procedures, local procedures and surgeries were associated with increased hospital cost and lengths of stay by 50.6%, 74.4%, 68.5%, and 7.4%, 50.6%, 4.6% respectively (each p<.001). Palliative care was associated with decreased hospital cost and length of stay by 28.6% and 4.6% (each, p<.001).

      The volume of life-sustaining treatments is the biggest driver of cost increase although there is a cost-saving effect from greater palliative care utilization at the end-of-life in dying lung cancer patients.
