Healthcare Utilization Disparities of Adolescent and Young Adults Compared to the Older Lymphoma Population

We assessed differences in health care utilization between the Adolescent and Young Adult (AYA) and older adult aggressive lymphoma population (n = 442). AYAs had a higher risk of having 4 or more acute care visits during the 2 years following diagnosis with more visits for substance use and psychiatric reasons. Our findings highlight the need for multidisciplinary, disease-targeted interventions amongst AYAs. Background: Adolescent and Young Adults (AYAs) are an underserved, high-risk population. Identifying health care utilization patterns, and particularly acute care visits, is important as these are high-intensity, expensive services. We investigated whether differences exist in health care utilization between the AYA lymphoma population compared to their older adult counterparts. Materials and Methods: Two correlated outcomes were used to measure health care utilization: 4 or more acute visits (emergency department or urgent care) and number of nonacute visits (office or telephone visits). We studied 442 patients with aggressive lymphoma patients 15 years or older at time of diagnosis managed at our cancer center within 2 years of their diagnosis. A multivariate generalized linear mixed model simultaneously estimated the effect of baseline predictors on 4 or more acute care visit with robust Poisson regression and nonacute visit counts with negative binomial regression allowing for a within-subject random effect. Results: AYAs had increased risk of having >= 4 acute visits (RR = 1.96; P = .047) compared to their older counterparts. Obesity (RR = 2.04, P = .015) and living less than 50 miles from the cancer center (RR = 3.48, P = .015) were independently associated with higher risk of acute care usage. Acute care visits for psychiatric or substance use related reasons were significantly higher ( P = .0001) among AYA (10/114, 8.8%) vs. non-AYA (3/328, 0.9%). Conclusion: Disease-targeted interventions to address high acute health care utilization is needed amongst AYAs. Additionally, early multidisciplinary involvement after cancer diagnosis particularly with psychiatric expertise amongst AYAs and palliative care involvement in both groups is needed.
