Last year of life of cancer patients who are adolescents and young adults (AYA): Inpatient patterns and disparities in a population-based study.

Abstract

126 Background: Cancer is the leading cause of non-accidental death among adolescents and young adults (AYA) in the US. The last year of life involves significant inpatient resources for older patients. We sought to determine the quantity and pattern of inpatient care for AYA cancer decedents in the last year of life to learn their healthcare system impact and groups to target for intervention. Methods: Using the California Office of Statewide Health Planning and Development private administrative database linked to death certificates, we performed a retrospective cross-sectional population-based analysis of patients aged 15-39 with cancer who died between 2000-2011. We calculated the number of admissions, hospital days, and percent of the cohort admitted each day in the last year of life. We determined the bed-day distribution across the population and the clinical and socio-demographic factors associated with high inpatient utilization. Results: The 9562 AYA cancer decedents were 45% non-Hispanic white, 30% Hispanic; 20% had hematologic malignancies, 70% had solid tumors. They were hospitalized, on average, 4.3 times and 40.6 days in the last year of life, increasing 3 months before death. Bed day occupation was skewed: 5% of the patients occupied 20% of the bed days and 18% occupied 50%. Factors associated with increased odds of being a top 5% utilizer were being Hispanic (OR: 1.48, 95% CI: 1.15-1.90, ref: non-Hispanic white), and having Acute Myelogenous Leukemia (AML) (2.7, 1.74-0.67, ref: Acute Lymphoblastic Leukemia (ALL). Factors associated with decreased odds were rural residence (0.39, 0.23-0.67, ref: urban), HMO insurance (0.58, 0.38-0.88, ref: private non-HMO), no hospitalizations at specialty centers (0.72, 0.53-0.97, ref: specialty center only), and having lymphoma or a solid tumor (ORs 0.035-0.39, CI range 0.005-0.56, ref: ALL). Conclusions: AYAs dying of cancer spent 40.6 days in the hospital in their last year of life (more than 1 in 9 days) with higher rates for Hispanics, AML patients, those with urban residence, and those hospitalized at specialty centers. Further research needs to determine what is driving these patterns, if they are preventable, and if they align with patient and family wishes.
