Measurement-based care (MBC) is a transtheoretical clinical process that uses patient-reported outcome measures to monitor treatment progress and to inform treatment planning and goal setting. Though ample evidence supports MBC as enhancing collaboration and improving outcomes, its practice is not the norm. One possible barrier to greater utilization of MBC in routine care is lack of consensus in the literature on what MBC is and how it should be practiced. In this article, we discuss this lack of consensus and detail the model for MBC developed by the Veterans Health Administration (VHA) MBC in Mental Health Initiative. Though it is simple, the VHA Collect, Share, Act model is consistent with the best clinical evidence to date and can serve as a guide for clinicians, health care systems, researchers, and educators.
