Abstract

Introduction: Cost-effectiveness is an essential tool for identifying high-value interventions in resource-limited settings. This study aims to evaluate the cost-effectiveness of the surgical management of fractures by surgical residents at Kamuzu Central Hospital (KCH). Currently, the 5-year surgical training program is supported by the Malawi Ministry of Health, and two universities in the United States and Norway.

Methods: We performed a modeled cost-effectiveness analysis (CEA) from a public health sector perspective. Cost data were collected from the current residency program and effectiveness data estimated from clinical data derived from operative interventions for fractures between 2013 and 2017 at KCH. Three patient groups were used as the base case; (1) patients of all ages, (2) patients age ≥18 years, and (3) patients who were <18 years. A Monte Carlo simulation of 10,000 trials was conducted for the probabilistic sensitivity analysis.

Results: The estimated average lifetime cost of training and compensating residency-trained surgeons over a 35-year career was $448,600 (SD $31,167). The incremental cost-effectiveness ratio (ICER) for providing surgical care to patients of all ages was $215 (SD $3,666) per disability-adjusted life-year (DALY), which is below the willingness-to pay-threshold (WTP) of $1,170 per DALY and highly cost-effective at a WTP threshold of $390. Each surgeon is estimated to avert approximately 5,570 DALYs during their career when performing operations to treat fractures.

Conclusion: The KCH surgical training program is highly cost-effective at reducing disability at an incremental cost of $215 per averted DALY. This CEA demonstrates that the current surgical training program is cost-effective in reducing morbidity among individuals with fractures.
