Examining service utilisation and impact among consumers of a national mental health stepped care programme in Australia: a protocol using linked administrative data
Abstract
Introduction Mental well-being is a global public health priority with increasing mental health conditions having substantial burden on individuals, health systems and society. ‘Stepped care’, where services are provided at an intensity to meet the changing needs of the consumer, is the chosen approach to mental health service delivery in primary healthcare in Australia for its efficiencies and patient outcomes; yet limited evidence exists on how the programme is being rolled out and its impact in practice. This protocol outlines a data linkage project to characterise and quantify healthcare service utilisation and impacts among a cohort of consumers of a national mental health stepped care programme in one region of Australia.Methods and analysis Data linkage will be used to establish a retrospective cohort of consumers of mental health stepped care services between 1 July 2020 and 31 December 2021 in one primary healthcare region in Australia (n=approx. 12 710). These data will be linked with records from other healthcare service data sets (eg, hospitalisations, emergency department presentations, community-based state government-delivered mental healthcare, hospital costs). Four areas for analysis will include: (1) characterising the nature of mental health stepped care service use; (2) describing the cohort’s sociodemographic and health characteristics; (3) quantifying broader service utilisation and associated economic costs; and (4) assessing the impact of mental health stepped care service utilisation on health and service outcomes.Ethics and dissemination Approval from the Darling Downs Health Human Research Ethics Committee (HREA/2020/QTDD/65518) has been granted. All data will be non-identifiable, and research findings will be disseminated through peer-reviewed journals, conference presentations and industry meetings.
