Abstract
BACKGROUND: Symptom control is prioritized by cancer patients and may improve overall survival. Ontario, Canada thus offers all cancer patients screening using the Edmonton Symptom Assessment System (ESAS) at outpatient cancer-related visits. We determined whether this initiative reached adolescents and young adults (AYA) and factors associated with screening in this population. METHODS: We linked all Ontario AYA diagnosed with cancer 2010-2018 aged 15-29 years to population-based databases identifying outpatient visits and ESAS screening. For each 2-week period in the year post-diagnosis, AYA with cancer-related visits were categorized as "unscreened" (no ESAS score) versus "screened" (≥1 ESAS score). Demographic and disease-related covariates were examined. RESULTS: Among 5435 AYA, 4204 (77.4%) had ≥1 ESAS screen. Within any 2-week period, only 30%-44% of AYA attending cancer-related visits were screened. Patients with hematologic malignancies were least likely to be screened [odds ratio (OR) vs. breast cancer 0.77, 95% confidence interval (95% CI) 0.67-0.88; p < 0.001]. AYA in remote Northern or rural areas had equivalent or higher rates of ESAS screening compared to those in high-income urban areas. However, AYA living in the lowest income urban neighborhoods were less likely to be screened (OR 0.86, 95% CI 0.77-0.97; p = 0.01). CONCLUSIONS: Within a population-wide symptom assessment program, while AYA living in rural and remote areas had high rates of screening, than those in low-income urban areas were substantially less likely to be screened. Though patients with hematologic cancers suffer from particularly high symptom burdens, they were also less likely to be screened. Interventions targeting AYA are required to increase uptake.
