Abstract
Background/Aims The collaborative care model for primary care of depression has a very strong evidence base, but has been little implemented. A statewide initiative (called DIAMOND) to implement it widely in Minnesota along with a new payment provided an opportunity for an embedded partnership research study of its implementation and impacts on the use of evidence-based care processes and depression symptoms for patients with depression.
Methods All 76 clinics participating in the staggered implementation initiative agreed to cooperate with the study. Potential patient subjects were identified from weekly submission of new antidepressant fills by seven health plans for a baseline and 6 month follow-up survey of care received and PHQ9 scores. Medical and administrative leaders of clinics completed implementation surveys at baseline and 1 and 2 years after implementation.
Results 2,348 patients with depression completed baseline surveys and 1,578 (67%) subjects completed 6 month follow-ups. Of those with follow-up data, 245 received DIAMOND care, 466 received usual care in DIAMOND clinics pre-implementation, 559 received usual care post-implementation, and 308 received usual care in clinics that signed up for DIAMOND but never implemented it. We have data on the extent of implementation and depression remission rates for each of these groups and they will be ready for presentation at the conference.
Conclusions To be announced at the conference.
