Abstract
INTRODUCTION: As life expectancy improves globally, the burden of elderly trauma continues to increase. Sub-Saharan Africa is projected to have the most rapid growth in its elderly demographic. Consequently, we sought to examine the trends in characteristics and outcomes of elderly trauma in a tertiary care hospital in Malawi. METHODS: We performed a retrospective analysis of adult patients in the trauma registry at Kamuzu Central Hospital (KCH) in Lilongwe, Malawi from 2011-2017. Patients were categorized into elderly (≥ 65 years) and non-elderly (18-64 years). Bivariate analysis compared the characteristics and outcomes of elderly vs. non-elderly patients. The elderly population was then examined over the study period. Poisson regression modeling was used to determine the risk of mortality among elderly patients over time. RESULTS: Of 63,699 adult trauma patients, 1,925 (3.0%) were aged ≥ 65 years. Among the elderly, the most common mechanism of injury was falls (n = 725 [37.7%]) whereas vehicle or bike collisions were more common in the non-elderly (n = 15,967 [25.9%]). Fractures and dislocations were more prevalent in the elderly (n = 808 [42.0%] vs. 9,133 [14.8%], p < 0.001). In-hospital crude mortality for the elderly was double the non-elderly group (4.8% vs. 2.4%, p < 0.001). Elderly transfers, surgeries, and length of stay significantly increased over the study period but mortality remained relatively unchanged. When adjusted for injury severity and transfer status, there was no significant difference in risk of in-hospital mortality over time. CONCLUSION: At KCH, the proportion of elderly trauma patients is slowly increasing. Although healthcare resource utilization has increased over time, the overall trend in mortality has not improved. As the quality of care for the most vulnerable populations is a benchmark for the success of a trauma program, further work is needed to improve the trend in outcomes of the elderly trauma population in Malawi.
