GAPS Phase III: incorporation of capacity based weighting in the global assessment for pediatric surgery.

Introduction: The Global Assessment for Pediatric Surgery (GAPS) tool was developed to enhance pediatric surgical care in Low- and Middle-Income Countries. This study presents the addition of a capacity-based weighting system to the GAPS tool.

Methods: GAPS, developed through a multi-phase process including systematic review, international testing, item analysis, and refinement, assesses 64 items across 5 domains: human resources, material resources, education, accessibility, and outcomes. This new weighting system differentially weighs each domain. The GAPS Score was evaluated using pilot study data, focusing on hospital and country income levels, human development index, under-five mortality rate, neonatal mortality rate, deaths due to injury and deaths due to congenital anomalies. Analysis involved the Kruskal-Wallis test and linear regression. Benchmark values for the GAPS overall score and subsection scores were identified.

Results: The GAPS score's capacity-based weighting system effectively discriminated between levels of hospital (p = 0.0001) and country income level (p = 0.002). The GAPS scores showed significant associations with human development index (p < 0.001) and key health indicators such as under-five mortality rates (p < 0.001), neonatal mortality rate (p < 0.001), and deaths due to injury (p < 0.001). Benchmark scores for the GAPS overall score and the subsection scores included most institutions within their respective hospital level.

Conclusions: The GAPS tool and score, enhanced with the capacity-based weighting system, marks progress in assessing pediatric surgical capacity in resource-limited settings. By mirroring the complex reality of hospital functionality in low-resource centers, it provides a refined mechanism for fostering effective partnerships and data-driven strategic interventions.
