Background and purposeFactors contributing to safety- or quality-related incidents (e.g. variances) in children are unknown. We identified clinical and RT treatment variables associated with risk for variances in a pediatric cohort.Materials and methodsUsing our institution's incident learning system, 81 patients age ≤21 years old who experienced variances were compared to 191 pediatric patients without variances. Clinical and RT treatment variables were evaluated as potential predictors for variances using univariate and multivariate analyses.ResultsVariances were primarily documentation errors (n = 46, 57%) and were most commonly detected during treatment planning (n = 14, 21%). Treatment planning errors constituted the majority (n = 16 out of 29, 55%) of near-misses and safety incidents (NMSI), which excludes workflow incidents. Therapists reported the majority of variances (n = 50, 62%). Physician cross-coverage (OR = 2.1, 95% CI = 1.04–4.38) and 3D conformal RT (OR = 2.3, 95% CI = 1.11–4.69) increased variance risk. Conversely, age >14 years (OR = 0.5, 95% CI = 0.28–0.88) and diagnosis of abdominal tumor (OR = 0.2, 95% CI = 0.04–0.59) decreased variance risk.ConclusionsVariances in children occurred in early treatment phases, but were detected at later workflow stages. Quality measures should be implemented during early treatment phases with a focus on younger children and those cared for by cross-covering physicians.
