A National Quality Improvement Collaborative for the clinical use of outcome measurement in specialised mental healthcare: results from a parallel group design and a nested cluster randomised controlled trial.

BACKGROUND: Although the importance and advantages of measurement-based care in mental healthcare are well established, implementation in daily practice is complex and far from optimal.

AIMS: To accelerate the implementation of outcome measurement in routine clinical practice, a government-sponsored National Quality Improvement Collaborative was initiated in Dutch-specialised mental healthcare.

METHOD: To investigate the effects of this initiative, we combined a matched-pair parallel group design (21 teams) with a cluster randomised controlled trial (RCT) (6 teams). At the beginning and end, the primary outcome 'actual use and perceived clinical utility of outcome measurement' was assessed.

RESULTS: In both designs, intervention teams demonstrated a significant higher level of implementation of outcome measurement than control teams. Overall effects were large (parallel group d =0.99; RCT d =1.25).

CONCLUSIONS: The National Collaborative successfully improved the use of outcome measurement in routine clinical practice.
