Societal costs of untreated perinatal mood and anxiety disorders in Vermont

Purpose To estimate the societal costs of untreated perinatal mood and anxiety disorders (PMADs) in Vermont for the 2018–2020 average annual birth cohort from conception through five years postpartum. Methods We developed a cost analysis model to calculate the excess cases of outcomes attributed to PMADs in the state of Vermont. Then, we modeled the associated costs of each outcome incurred by birthing parents and their children, projected five years for birthing parents who do not achieve remission by the end of the first year postpartum. Results We estimated that the total societal cost of untreated PMADs in Vermont could reach $48 million for an annual birth cohort from conception to five years postpartum, amounting to $35,910 in excess societal costs per birthing parent with an untreated PMAD and their child. Conclusion Our model provides evidence of the high costs of untreated PMADs for birthing parents and their children in Vermont. Our estimates for Vermont are slightly higher but comparable to national estimates, which are $35,500 per birthing parent–child pair, adjusted to 2021 US dollars. Investing in perinatal mental health prevention and treatment could improve health outcomes and reduce economic burden of PMADs on individuals, families, employers, and the state.
