Barriers and Facilitators to Mental Health Service Integration: A Scoping Review

Mental health service integration currently has no consensus definition and exists in a variety of settings, including primary care, addiction treatment and chronic disease management, and mental health nurses have often experienced efforts at service integration with varying degrees of success. The intent of mental health service integration is to enable collaboration between mental health services and other healthcare providers to improve service access and the care provided to individuals with mental health issues or mental illness. This scoping review aimed to explore service integration between mental health services and with a specific focus on those evaluated in peer-reviewed, primary literature, to determine facilitators and barriers to service integration. Using the Arksey and O'Malley's framework for scoping reviews, we located 3148 studies, with screening narrowing final papers for inclusion to 18. Facilitators to service integration included clinician education, adequate resourcing and an interdisciplinary approach, while barriers included staff factors such as a reluctance to work with individuals with mental illness, consumer level barriers such as poor mental health literacy, ‘territorialism’ among staff and organisational climate. Research indicates that service integration is an effective means to detect and treat mental health issues in settings that do not traditionally provide mental health care, lowering the costs of providing healthcare and providing improved care for mental health needs; however, there are several barriers to be addressed to achieve full implementation of integration models.
