Mental health integrated care models in primary care and factors that contribute to their effective implementation: a scoping review.

Background: In the state of Victoria, Australia, the 111-day lockdown due to the COVID-19 pandemic exacerbated the population's prevailing state of poor mental health. Of the 87% of Australians who visit their GP annually, 71% of health problems they discussed related to psychological issues. This review had two objectives: (1) To describe models of mental health integrated care within primary care settings that demonstrated improved mental health outcomes that were transferable to Australian settings, and (2) To outline the factors that contributed to the effective implementation of these models into routine practice.

Methods: A scoping review was undertaken to synthesise the evidence in order to inform practice, policymaking, and research. Data were obtained from PubMed, CINAHL and APA PsycINFO.

Results: Key elements of effective mental health integrated care models in primary care are: Co-location of mental health and substance abuse services in the primary care setting, presence of licensed mental health clinicians, a case management approach to patient care, ongoing depression monitoring for up to 24 months and other miscellaneous elements. Key factors that contributed to the effective implementation of mental health integrated care in routine practice are the willingness to accept and promote system change, integrated physical and mental clinical records, the presence of a care manager, adequate staff training, a healthy organisational culture, regular supervision and support, a standardised workflow plan and care pathways that included clear role boundaries and the use of outcome measures. The need to develop sustainable funding mechanisms has also been emphasized.

Conclusion: Integrated mental health care models typically have a co-located mental health clinician who works closely with the GP and the rest of the primary care team. Implementing mental health integrated care models in Australia requires a 'whole of system' change. Lessons learned from the Mental Health Nurse Incentive Program could form the foundation on which this model is implemented in Australia.
