Screening for distress in lung and breast cancer outpatients: a randomized controlled trial.

Purpose: Distress has been recognized as the sixth vital sign in cancer care and several guidelines recommend routine screening. Despite this, screening for distress is rarely conducted and infrequently evaluated.

Methods: A program of routine online screening for distress was implemented for new patients with breast and lung cancer. Patients were randomly assigned to one of three conditions: (1) minimal screening: the distress thermometer (DT) only plus usual care; (2) full screening: DT, problem checklist, Psychological Screen for Cancer part C measuring anxiety and depression, a personalized report summarizing concerns and the report on the medical file; or (3) triage: full screening plus optional personalized phone triage with referral to resources. Patients in all conditions received an information packet and were reassessed 3 months later with the full screening battery.

Results: Five hundred eighty-five patients with breast cancer and 549 patients with lung cancer were assessed at baseline (89% of all patients), and 75.5% retained for follow-up. High prevalence of baseline distress was found across patients. Twenty percent fewer patients with lung cancer in triage continued to have high distress at follow-up compared to those in the other two groups, and patients with breast cancer in the full screening and triage conditions showed lower distress at follow-up than those in minimal screening. The best predictor of decreased anxiety and depression in full screening and triage conditions was receiving a referral to psychosocial services.

Conclusion: Routine online screening is feasible in a large cancer center and may help to reduce future distress levels, particularly when coupled with uptake of appropriate resources.
