Abstract

Although pediatric cancer survivors in the United States are at an increased risk of developing chronic conditions, to the authors' knowledge there is limited information regarding the types and combinations of conditions they experience in the years immediately after the completion of cancer therapy. An observational cohort study of early pediatric cancer survivors (children who were ≥2 years from the end of therapy and aged ≤18 years) was conducted using the Truven Health MarketScan (r) Commercial Claims and Encounters database (2009-2014). Latent class analysis was used to identify comorbidity groups among the subset with ≥2 conditions. Group-level health care use was compared with survivors without chronic conditions using multivariate regression. A total of 3687 early survivors were identified, of whom approximately 41.2% had no chronic conditions, 22.5% had 1 chronic condition, and 36.3% had ≥2 chronic conditions. Among those with ≥2 chronic conditions, 5 groups emerged: 1) general pediatric morbidity (35.4%); 2) central nervous system (CNS) (22.4%); 3) mental health conditions (22.2%); 4) endocrine (26.2%); and 5) CNS with endocrine (3.8%). The CNS group experienced the highest expenditures, at $17,964 more per year (95% CI, $1446-$34,482) compared with survivors without chronic conditions. The CNS group also had the highest odds of an emergency department visit (adjusted odds ratio, 1.71; 95% CI, 1.15-2.56). The endocrine group had the highest odds of hospitalization (odds ratio, 2.29; 95% CI, 1.24-4.22). Multimorbidity is common among pediatric cancer survivors. The current study identified 5 distinct comorbidity subgroups, all of which experienced high, yet differential, rates of health care use. The results of the current study highlight the complex health care needs of early survivors and provide evidence for the design of targeted survivorship services and interventions. © 2019 American Cancer Society.
