For When Australian perinatal and infant mental health navigation programme: evaluation protocol

Introduction Many parents and carers experience mental health challenges during pregnancy and early postpartum years, and there are cumulative shortfalls in the identification, follow-up, and treatment of those experiencing perinatal and infant mental health (PIMH) challenges. ForWhen is a new national navigation programme in Australia that aims to improve outcomes for families by supporting parents and carers to access PIMH services that best meet their needs. This paper presents the protocol of an evaluation of the ForWhen programme, to be conducted over the first 3 years of its implementation. The specific objectives of the evaluation include examining the characteristics of navigation service delivery, its implementation and clinical impact, and identifying potential moderators of change. Methods and analysis Utilising a mixed-methods design, this evaluation will incorporate three phases that reflect the stages of the programme life-cycle: (1) programme description, (2) implementation evaluation and (3) outcomes evaluation. The evaluation will use a mix of quantitative and qualitative data including deidentified routinely collected service data, participant observations, semistructured interviews, surveys and questionnaires, and a resource audit. DiscussionEvaluation findings will be used to inform the development of a refined clinical navigation model, identify barriers and facilitators to successful navigation programme implementation, examine the impact of the ForWhen programme on client clinical outcomes and health service utilisation, understand how the programme is/can be best embedded in the evolving service system, and assess the cost-effectiveness and sustainability of a national navigation programme in improving health outcomes for PIMH in Australia.
