Abstract

Introduction: Previous societal burden estimations for major depressive disorder (MDD) often fail to account for several hidden cost components. This study provides a comprehensive evaluation of societal costs for adults with MDD in the United States (USA) in 2019. The potential impact of a more effective, rapid-acting MDD therapy vs standard of care on the economic burden of MDD was estimated to illustrate the utility of such a framework in evaluating new interventions.

Methods: This study used a prevalence-based human capital approach. Incremental costs (2019 US dollars) per individual with MDD were derived from national survey inputs and published literature and included incremental healthcare costs and indirect costs. For each cost component, the societal costs were extrapolated by multiplying the per-patient costs by the number of individuals with MDD. The impact of a more effective, rapid-acting novel therapy on the economic burden of MDD was then simulated on the basis of these inputs.

Results: In 2019, the number of adults with MDD in the USA was estimated at 19.8 million (62.7% female; 32.9% severe MDD), and the incremental societal economic burden of MDD was estimated at $333.7 billion ($382.4 billion in 2023 US dollars), or $16,854 per adult with MDD. The primary cost drivers were healthcare costs ($127.3 billion; 38.1%), household-related costs ($80.1 billion; 24.0%), presenteeism ($43.3 billion; 13.0%), and absenteeism ($38.4 billion; 11.5%). In the simulated scenario, a hypothetical novel therapy with a 50.0% early response rate was associated with a 7.7% reduction in the economic burden of MDD relative to standard of care over 12 months.

Conclusions: The economic burden of MDD is substantial and extends beyond healthcare costs, underscoring the impact of MDD across multiple aspects of life. Such a broad societal perspective should be considered in assessing the impact of the advent of effective, rapid-acting MDD therapies.

MDD population in the USA in 2019a. MDD, major depressive disorder; MDE, major depressive episode; NHANES, National Health and Nutrition Examination Survey; NSDUH, National Survey on Drug Use and Health; PHQ-9, Patient Health Questionnaire-9. a The severity of MDD was based on the proportion of patients with moderate to severe depression symptoms, which was defined using the PHQ-9 categories of moderate (score 10–14) and severe (score ≥ 15). Of note, the severity proportions were applied to the population of adults with MDD under the assumption that patients with at least 1 MDE in the past year (definition in the NSDUH) are represented by patients with PHQ-9 score of ≥ 10 (definition of moderate and severe MDD in NHANES). Therefore, it was assumed that no patients with mild depressive symptoms (PHQ-9 score of < 10) would qualify for MDD
