Cost analysis of outpatient services for major external structural birth defects: an ingredient approach in selected hospitals in Kiambu County, Kenya.

Introduction: major external structural birth defects (MESBDs) are known to exert an enormous economic burden on individuals and health services; however, they have been vastly underprioritized as a public health problem in settings where cost analyses are limited. This study aimed at conducting a cost analysis of outpatient services for MESBDs in selected hospitals in Kiambu County, Kenya.
Methods: a cross-sectional descriptive survey was conducted in four hospitals selected for providing outpatient corrective and rehabilitative services to the under-fives. An ingredient approach was used to gather data retrospectively on the cost drivers for castings, bracings, and tendonectomies from healthcare providers' perspectives for a one-year time horizon from January 1 ^st , 2018, to December 31 ^st , 2018. Prevalence-based morbidity data were extracted from outpatient occupational therapy clinic registers, whereas staff time was gathered through face-to-face inquiries. Associated cost drivers of 349 cases were quantified, valued using prevailing market prices, and categorized as recurrent costs. The unit economic costs were calculated as average costs, expressed in U.S. dollars, and inflated to the U.S. dollar Consumer Price Index from January 2018 to December 2018.
Results: the unit economic cost of all the cases was estimated at $1,139.73; $1,143.51 for neural tube defects (NTDs), $1,143.05 for congenital talipes equinovarus (CTEV), and $1,109.81 for congenital pes planus.
Conclusion: the highest economic burden of MESBDs was associated with NTDs, and CTEV, respectively. We recommend further research to estimate the economic costs of MESBDs among school-going pupils to inform the equitable allocation of resources for health and childhood developmental programs.
