Community-based palliative care and end-of-life care in elderly patients with pancreatic cancer.

Abstract

70 Background: No population-based studies have evaluated the impact of community-based palliative care (CBPC) on aggressive end-of-life (EOL) care use and Medicare charges for elderly pancreatic cancer patients. We analyzed the impact of CBPC on aggressive EOL care use in the last 30 days of life and on emergency department (ED) and intensive care unit (ICU) Medicare charges using the SEER-Medicare data. Methods: 12399 elderly pancreatic cancer patients survived for at least 1 month after diagnosis from 2007 to 2013 were identified. CBPC and hospital-based palliative care (HBPC) users were identified by diagnosis codes and place of services and matched by the coarsened exact matching [786:786; age, sex, residence urbanization level, comorbidities, illness duration, palliative care (PC) exposure]. Zero-inflated Poisson and multivariable logistic/linear regression models examined the variations of aggressive EOL care use in the matched patients. Generalized linear regression with a gamma distribution determined how CBPC impacted ED and ICU Medicare charges. Results: 22.1% eligible patients (median age: 76 years) used PC in the 6 years, including 7.7% who used CBPC and 14.5% who used HBPC. The median duration from cancer diagnosis to death of CBPC, HBPC and Non-PC users was 11 months, 6 months and 8 months (P < .001). Matched CBPC users were less likely than HBPC users to be admitted to ICU (risk ratio [RR], 0.64; 95% CI, 0.50-0.81), ED (RR, 0.63; 95% CI, 0.53-0.73), and hospital (RR, 0.50; 95% CI, 0.35-0.72). Compared to matched HBPC users, CBPC users utilized less life-extending care (OR, 0.59; 95% CI, 0.43-0.80) and had shorter hospital (Coef., −0.42; 95% CI, −0.65- −0.18) and ICU stays (Coef., −0.35; 95% CI, −0.59 - −0.10). They tended to die at home (OR, 1.46; 95% CI, 1.19-1.78) and not in ED/ICU/hospital settings (OR, 0.62; 95% CI, 0.45-0.83). CBPC users’ adjusted mean ED and ICU Medicare charges were 0.2% (P = .80) and 1.1% (P < .001) lower than those of Non-PC users and 4.5% (P = .43) and 21.0% (P = .08) lower than those of matched HBPC users. Conclusions: CBPC users utilized less aggressive EOL care than HBPC users, implying CBPC's potential to reduce aggressive EOL care use. Their ICU Medicare charge was lower than that of Non-PC users.
