Costs and benefits of scaling psychosocial interventions during the perinatal period in England: A simulation modelling study

Abstract

BackgroundGlobally, guidance recommends the integration of mental health into maternal and child healthcare to address common maternal mental health problems during the perinatal period. However, implementing this in the real-world requires substantial resource allocations. ObjectiveThe aim of this study was to estimate the likely costs and consequences linked to scaling the delivery of treatment (in the form of psychosocial interventions) during the perinatal period. DesignSimulation modelling. Setting(s)England. MethodsCosts and consequences were modelled for three scenarios of assumed provision of services, whereby one referred to the projected provision under current government plans, with no additional scaling up of treatment. The other two scenarios referred to additional scaling of treatment: in one scenario, this referred to the provision of treatment by midwives and health visitors trained in the routine enquiry about mental health and delivery of psychosocial interventions; in the other scenario this referred to an expanded provision by primary mental health services. For each scenario and in yearly intervals (covering a ten-year period, 2015 to 2024), unit cots and outcomes were assigned to the activities women were assumed to receive (routine enquiry, assessment, treatment, care coordination). All costs were in 2020 pounds sterling. Data sources for the modelling included: published findings from randomised controlled trials; national unit cost source; national statistics; and expert consultation. ResultsIf the projected treatment gap was to be addressed, an estimated additional 111,154 (50,031) women would be accessing treatment in 2015 (2024). Estimated total costs (including cost offsets) in the scenario of projected provision under current government plans would be £73.5 million in 2015 and £95.2 million in 2024, whilst quality-adjusted life years gained would be 901 and 928 respectively. Addressing the treatment gap through provision by trained midwives and health visitors could mean additional costs of £7.3 million in 2015 but lower costs of £18.4 million in 2024. The additional quality-adjusted life years gained are estimated at 2096 in 2015 and 1418 in 2024. A scenario in which the treatment gap would be met by primary mental health services was likely to be more costly and delivered less health gains. ConclusionsFindings from this modelling study suggest that scaling the integration of mental health care into routinely delivered care for women during the perinatal period might be economically viable.
