Patient-reported outcome measures for monitoring primary care patients with depression: the PROMDEP cluster RCT and economic evaluation.

Background: Guidelines on the management of depression recommend that practitioners use patient-reported outcome measures for the follow-up monitoring of symptoms, but there is a lack of evidence of benefit in terms of patient outcomes.

Objective: To test using the Patient Health Questionnaire-9 questionnaire as a patient-reported outcome measure for monitoring depression, training practitioners in interpreting scores and giving patients feedback.

Design: Parallel-group, cluster-randomised superiority trial; 1 : 1 allocation to intervention and control.

Depression follow-up monitoring with the PHQ-9: an open cluster-randomised controlled trial.

Aim: To test monitoring depression using the Patient Health Questionnaire (PHQ-9) with patient feedback.

Design And Setting: An open cluster-randomised controlled trial was undertaken in 141 group practices.
