Evaluating the clinical efficacy of a primary care-focused, nurse-led, consultation liaison model for perinatal mental health

In Australia, perinatal mental illness is common, although poorly identified and treated. Improved perinatal mental health depends on service provision models that reflect a focus on promotion, prevention, and early intervention, while facilitating improved referral pathways between primary health and specialist mental health services. In 2008, a contemporary community-based model of mental health service provision was developed as an alternative to the pre-existing hospital-based service model. The model is delivered primarily by mental health nurses using a consultation liaison framework. It provides for specialist mental health assessment and brief intervention in collaboration with the general practitioner, who remains the primary health provider. It also aims to raise community awareness and build capacity for the management of perinatal disorders in the primary care sector. Evaluation of the clinical effectiveness of the model, and the improvement in access for primary health providers and women, was conducted at 2 years from its implementation. Clinical effectiveness was evaluated by using comparative data from the Edinburgh Depression Scale and Depression Anxiety and Stress Scale, and the results demonstrated clinical efficacy. Improved attendance rates indicated that women preferred this community-based service model as an alternative to the pre-existing service model.
