Late Effects Screening of Acute Lymphoblastic Leukemia Survivors in the Military Healthcare System.

Pediatric acute lymphoblastic leukemia (ALL) survivors are a growing portion of the population with unique health screening needs. These survivors receive care within late effects oncology clinics and primary care clinics. Prior attempts to quantify compliance with follow-up recommendations have shown variable rates ranging from 28% to 73%. This study set out to assess rates of adherence to recommended health screening among pediatric ALL survivors within the U.S. DoD, identify potential risk factors contributing to patient compliance, and better define the prevalence of chronic health conditions. This Institutional Review Board-approved, retrospective cohort study used data from the U.S. DoD MHS database and identified incident cases of pediatric ALL during 2007-2011 using a conservative case identification algorithm. Minimum duration of follow-up was instituted in order to ensure the entire study population had sufficient time for the assessment of each screening exam according to recommended guidelines. Rates of adherence to recommended screening measures were calculated across the full study follow-up period, and regression analyses assessed protective factors for compliance. One hundred and forty-four incident ALL cases were identified. During the follow-up period, 31.3% developed a new mental health diagnosis. In terms of recommended screening, 94.4% had an annual complete blood count for the entire study period, 90.3% had a liver function screening, 81.9% had an echocardiogram, 34% had a bone density scan, and 54.2% had a mental health visit. Adolescents were less likely to have a bone density scan (odds ratio [OR] 0.32, 95% CI, 0.11-0.95) or a mental health visit (OR 0.28, 95% CI, 0.11-0.7). The MHS provides universal access to healthcare for all beneficiaries. In this population with universal access to care, there is increased compliance with screening recommendations. Our results reflect actual screening testing as opposed to general screening visits that have been previously reported in the literature. We also highlight the significant number of mental health diagnoses among pediatric ALL survivors.
