Design and Implementation of a Hospital-based Trauma Surveillance Registry in a Resource-Poor Setting: A Cost Analysis Study.

Introduction: Trauma is a leading cause of morbidity and mortality globally, with a disproportionate burden affecting low- and middle-income countries (LMIC). Rapid urbanization and differences in transportation patterns result in unique injury patterns in LMIC. Trauma registries are essential to determine the impact of trauma and the nature of injuries in LMIC to enable hospitals and healthcare systems to optimize care and to allocate resources.

Methods: A retrospective database analysis of prospectively collected data in the Kamuzu Central Hospital (KCH) Trauma Registry from 2018 - 2019 was performed. Activity-based costing, a bottom-up cost analysis method to determine the cost per patient registered, was completed after systematically analyzing the standard operating procedures of the KCH trauma registry.

Results: During the study period, 12,616 patients were included in the KCH Trauma Registry. Startup costs for the trauma registry are estimated at $3,196.24. This sum includes $1815.84 for personnel cost, $200 for database initiation (REDCap database), $342.50 for initial data clerk training, and $787.90 for registry and office supplies. Recurrent costs occurring in 2018, included personnel, technology, supply, and facility costs. Five data clerks, one data clerk manager, and a registry manager are required for 24/7 data collection, data integrity, and database maintenance, with an estimated cost of $29,697.24 per year. Yearly recurrent data clerk training costs are $137.00. Internet and facility costs for a data clerk office and secure record storage are $1632.60 per year. Supplies for the completion of trauma intake forms (binders, paper, pens) are $1431.80 per year. The total annual cost of the trauma registry at a tertiary hospital in Malawi is $33,361.64, which costs $2.64 per patient registered in the registry in 2018.

Conclusion: Trauma registries are necessary for the assessment of the local trauma burden and injury pattern, but require significant financial commitment and time. To fully capture the local burden of trauma in resource-limited settings, acquiring, validating, and analyzing accurate data is crucial. Anticipating the financial burden of a trauma surveillance registry ahead of time is imperative.
