Nathan PC, et al. - In a population-based cohort of Ontario adolescents (15.0-17.9 years) diagnosed with cancer between 1995 and 2010, researchers assessed the relative health care utilization (hospitalizations, emergency department visits, same-day surgeries, outpatient chemotherapy, radiation, diagnostic/laboratory tests, physician services, home care) and costs (2012 Canadian dollars) among adolescents treated for cancer in pediatric or adult institutions. These comparisons were carried out in prediagnosis (60 days), initial (360 days), continuing (variable), and terminal (360 days) care phases. Overall 691 eligible adolescents received care in adult institutions and 665 in pediatric institutions. In pediatric vs adult institutions, considerably higher costs of caring were faced by adolescents with the same malignancy as noted during most treatment phases. Much of the cost difference was driven by resource utilization, especially hospitalization.
