Effect of palliative care on economic burden in lung cancer admissions: Insights from the NIS database.

12081 Background: Lung cancer (LC) remains the leading cause of cancer mortality globally, presenting substantial challenges in symptom management and quality of life (QoL) for affected patients. Despite the crucial role of palliative care (PC) in alleviating suffering and enhancing QoL, its integration into LC treatment is inconsistent, attributed to healthcare provider perceptions and systemic barriers. This study examines the utilization of PC consultations in LC admissions using the National Inpatient Sample (NIS) database, seeking to identify patterns of use and opportunities for improved care integration. Methods: The study queried the NIS database from 2016 to 2020 for adult hospitalized patients with a primary diagnosis of LC using ICD-10 codes. The primary outcome examined was the impact of PC consultations on length of stay (LOS), total hospital charges (THC), and healthcare utilization, with inpatient mortality as a secondary outcome. Baseline characteristics were assessed using t-tests and chi-square tests, while multivariable logistic regression analysis adjusted for age, gender, race, Charlson index, insurance type, and household income was employed to evaluate the outcomes. Results: Among 584, 055 LC patients, 50. 4% was female and 14. 6% had a PC consult. These patients were typically older (68. 4 vs. 70. 6 years, p <0. 001), more likely to be male (51. 1% vs. 49. 3%, p < 0. 001) and African American (13. 3% vs. 11. 9% p < 0. 001), and had Medicaid coverage (11. 1% vs. 9. 7%, p < 0. 001) compared to their counterparts. PC was more frequently consulted in non-teaching hospitals (16. 3% vs 14. 1%, p < 0. 001). Patients with PC consults also had a higher Charlson Comorbidity index 6. 4 vs. 4. 9 (p < 0. 001). The overall inpatient mortality rate was 7. 4%, with a significantly higher rate in patients with PC (32%) versus without (3. 2%) (p < 0. 001). While PC was associated with a longer LOS (7. 6 vs. 5. 9 days, p < 0. 001), it resulted in lower THC (74, 399 vs. 84, 233, adjusted difference: 6, 874 p < 0. 0001) and increased discharges with home health care and to nursing homes. Conclusions: PC consultations in LC patients are associated with reduced THC despite a slight increase in LOS. This finding emphasizes the economic and therapeutic value of PC in the treatment of LC, advocating for its earlier and broader integration. By addressing both symptom management and healthcare costs, palliative care can play a significant role in enhancing the comprehensive care of lung cancer patients, highlighting the need for overcoming existing barriers to its adoption.
