Randomized Controlled Trial
Depression follow-up monitoring with the PHQ-9: open cluster-randomised controlled trial.
Outcome monitoring of depression treatment is recommended but there is a lack of evidence on patient benefit in primary care. ⋯ No evidence was found of improved depression outcome at 12 weeks from monitoring. The findings of possible benefits over 26 weeks warrant replication, investigating possible mechanisms, preferably with automated delivery of monitoring and more instructive feedback.
