Road traffic crashes and assault drove most trauma visits in Yaoundé

A year of emergency ward data from Central Hospital of Yaoundé shows how sharply injury patterns can define a city’s trauma burden. In 2007, 6,234 injured people were treated at the hospital’s emergency ward, making the dataset a substantial snapshot of trauma care in Cameroon’s capital. The age and sex distribution alone points to a familiar but still urgent pattern: 71% of patients were male, and the mean age was 29 years, with a standard deviation of 14.9. In practical terms, the burden fell heavily on young adults in the years when social mobility, commuting, work exposure, and street-level risk are often highest.

Road traffic injury dominated the case mix. Nearly 60% of all injuries resulted from crashes, and 46% of those events involved a pedestrian. That combination is especially important in an urban setting where pedestrian exposure, traffic density, and limited separation between vehicles and people on foot can turn routine movement into a high-risk activity. When pedestrians account for such a large share of crash-related trauma, the problem is no longer just motor vehicle safety; it becomes a broader issue of street design, traffic behavior, enforcement, and emergency readiness.

Intentional injury formed the second major category, accounting for 22.5% of cases. More than half of those intentional injuries involved unarmed assault, a detail that places interpersonal violence firmly inside the trauma profile of the hospital. This matters clinically because assault injuries often differ from crash-related trauma in mechanism, associated soft tissue damage, and the social circumstances that bring patients to care. They also signal a burden that extends beyond surgery and emergency medicine into community safety, conflict exposure, and prevention strategies that reach outside the hospital walls.

The distribution of injury mechanisms tells a clear story about where risk concentrates. Young men were the predominant group, which mirrors trauma epidemiology in many settings where occupational exposure, transportation patterns, and violence risk are concentrated among males in early adulthood. Even without more granular occupational data, the demographic pattern is strong enough to suggest that the highest-risk patients were those most likely to be moving through the city, traveling on foot, or involved in social environments where violence can occur.

Falls occupied a smaller share of the injury burden, but they carried a more serious disposition signal: patients injured in falls were more likely to be admitted to the hospital. The abstract stops short of giving the full statistical details, but the admission pattern itself suggests greater severity or a higher likelihood of injuries requiring inpatient observation, procedures, or prolonged care. In trauma practice, falls can range from minor to devastating, and the subset that results in admission often reflects substantial musculoskeletal, head, or multisystem injury. Even in a dataset dominated by road trauma, that admission pattern should not be dismissed.

What the emergency ward data reveal about prevention priorities

This hospital-based review does more than count injuries. It shows how a single urban emergency ward can become a window into a city’s injury ecology. The overwhelming share of road traffic trauma points toward transportation safety as a central intervention target, especially where pedestrians make up nearly half of crash victims. A pedestrian-heavy crash pattern often implies vulnerable road users, inadequate crossing infrastructure, poor traffic calming, or a mismatch between vehicle speed and city streets designed for mixed use.

The prominence of intentional injury adds another layer. Violence prevention cannot be separated from trauma care when more than one in five injuries is intentional. Unarmed assault, in particular, may be invisible in routine policy discussions because it lacks the dramatic profile of firearms or explosive injury, yet it still consumes emergency resources and leaves patients with real physical and psychological harm. Hospitals in settings like Yaoundé are often the first and only point of contact for these injuries, which means the emergency ward becomes a critical surveillance site as well as a treatment site.

The study also reinforces the value of basic administrative data. A retrospective review of age, sex, mechanism of injury, and outcome may sound modest, but in countries where injury surveillance is limited, that information can still reveal the dominant causes of trauma and the groups at highest risk. The absence of more detailed injury coding or long-term follow-up does not erase the public health signal. It makes the signal easier to see: trauma in this setting is not random, and it is not evenly distributed across the population.

For clinicians, the findings are a reminder that trauma systems have to be built around the injuries they actually see. For public health teams, the pattern argues for integrated prevention: safer roads for pedestrians, enforcement of traffic rules, community measures that reduce violence, and hospital surveillance that can track whether interventions change the mix of injuries over time. The dataset comes from one year and one hospital, so it cannot describe the entire country or prove trends beyond 2007. Even so, it captures a large burden of preventable injury and places a spotlight on the young men, pedestrians, and violence-related cases most likely to define emergency care in Yaoundé.

The study leaves one essential question open: whether these patterns persisted after 2007 or changed with shifts in urban traffic, policing, and health system capacity. The hospital data establish the burden; they do not yet show how much of it can be redirected by prevention, infrastructure, or policy.
