Paediatric integrated care (PIC), which involves primary care and behavioural health clinicians working together with patients and families, has been promoted as a best practice in the provision of care. In this context, behavioural health includes behavioural elements in the care of mental health and substance abuse conditions, chronic illness and physical symptoms associated with stress, and addressing health behaviours. Models of and contexts in which PIC has been applied vary, as do the outcomes and measures used to determine its value. Thus, this study seeks to better understand (1) what paediatric subpopulations are receiving integrated care, (2) which models of PIC are being studied, (3) what PIC outcomes are being explored and what measures and strategies are being used to assess those outcomes, and (4) whether the various models are resulting in positive outcomes. These questions have significant policy and clinical implications, given current national- and state-level efforts aimed at promoting integrated health care.
