[Comment] The promise of scalable symptom surveillance with stepped collaborative care in oncology

Guidelines for managing deleterious symptoms from cancer and its treatments have been largely underused in practice. To address this problem, the National Cancer Institute launched the Improving the Management of Symptoms During and Following Cancer Treatment (IMPACT) consortium,1 an alliance of three research centres leading large-scale trials of electronic patient-reported outcome measure (ePROM) symptom surveillance and management systems. Andrea L Cheville and colleagues2 report findings from one IMPACT trial, showing positive effects of an enhanced, electronic health record (EHR)-facilitated cancer symptom control (E2C2) intervention on patients' and survivors' symptom burden and health-care use.
