Cost-Effectiveness Analysis of Two Integrated Early Childhood Development Programs into Bangladeshi Primary Health-Care Services.

Objectives: This study presents results of cost and cost-effectiveness analysis of two parenting interventions (group-based and pairs) integrated into primary health care centers in rural Bangladesh.

Methods: A within-trial cost-effectiveness analysis was conducted from the provider perspective. Incremental cost effectiveness ratios were estimated for all primary child development outcomes and presented in terms of cost per standard deviation improvements in the outcomes. A series of cost scenario analyses were conducted to assess the effect of changing cost assumptions on the cost and cost-effectiveness results. All results are presented in 2022 USD.

Results: Total provider costs in the within-trial analysis were US$ 67,668 for the group-based intervention and US$ 117,028 for the pair intervention. Estimated cost per child covered by the interventions was US$156 for the group intervention and US$136 for the pair intervention, reflecting likely economies of scale in delivery of the pair intervntion. An additional US$100 expenditure on the group intervention is estimated to lead to a 0.55 SD improvement in cognition, 0.44 SD in language development and 0.33 SD in motor development. For the pair intervention, the corresponding estimates are improvements of 0.95 SD, 0.81 SD, and 0.88 SD, respectively. Under potential scale up scenarios, intervention cost can reduce substantially resulting in cost per child of US$44 and US$47 for group and pair interventions, respectively.

Conclusion: The findings indicates that cost-efficiency and cost-effectiveness results for both interventions are comparable with the results from limited similar interventions in LMICs. However, implementation costs of the interventions will be substantially lower at scale due to lower monitoring costs, economies of scale, and full integration into the public health system.
