Cost of adapting the International Guide for Monitoring Child Development, Guatemala and India

To assess the cost of co-creating an adaptation of the International Guide for Monitoring Child Development (intervention for use by community health workers (CHWs)) in rural Guatemala and India.

We developed survey instruments to capture the costs, from health-system and societal perspectives, of adapting the guide with local partners and international experts in the two sites. We included the costs of human resources, information technology, and infrastructure and logistic support. To improve the transparency and comparability of cost estimates, we reported the required resources for adaptation, such as time and expertise of human resources, and the quantity, function and usage time of the resources used.

Adaptation of the guide took 14 months in India and 18 months in Guatemala during 2021-2022. Total costs by site were 38 174.57 United States dollars (US$) in Guatemala, US$ 39 287.15 in India and US$ 81 846.59 for international consultants. International consultants accounted for about half of the costs, and the Guatemala and India sites each accounted for about a quarter of the costs. Human resources were the largest contributor to the adaptation costs in both sites (90.1%; 34 398.20/38 174.57 in Guatemala and 94.8%; 37 262.74/39 287.15 in India) followed by infrastructure support and information technology.

Since most of the required steps to adapt the guide for use by CHWs have now been done by our study, we expect future adaptation costs to be lower. The methods used in this study provide an example of how to cost intervention adaptations in the future.
