Epidemiology and cost of pediatric injury in Yaoundé, Cameroon: a prospective study.

PURPOSE: Unintentional injury is the leading cause of death among children aged 10-19 years and over 95% of injury deaths occur in low- and middle-income countries (LMICs). As patterns of injury in the pediatric population may differ from those in adults, risks specific to children in LMICs need to be identified for effective injury prevention and treatment. This study explores patterns of pediatric injury epidemiology and cost in Yaoundé, Cameroon to inform injury prevention and resource allocation. METHODS: Pediatric (age < 20 years) trauma patient data were collected at the emergency department (ED) of Central Hospital of Yaoundé (CHY) from April through October 2009. Univariate, bivariate, and multivariate analyses were used to explore injury patterns and relationships between variables. Regression analyses were conducted to identify predictors of receiving surgical care. RESULTS: Children comprised 19% (544) of trauma cases. About 54% suffered road traffic injuries (RTIs), which mostly affected the limbs and pelvis (37.3%). Half the RTI victims were pedestrians. Transportation to CHY was primarily by taxi or bus (69.4%) and a preponderance (71.1%) of the severely and profoundly injured patients used this method of transport. Major or minor surgical intervention was necessary for 17.9% and 20.8% of patients, respectively. Patients with an estimated injury severity score ≥ 9 (33.2%) were more likely to need surgery (p < 0.01). The median ED cost of pediatric trauma care was USD12.71 [IQR 12.71, 23.30]. CONCLUSIONS: Injury is an important child health problem that requires adequate attention and funding. Policies, surgical capacity building, and health systems strengthening efforts are necessary to address the high burden of pediatric injuries in Cameroon. Pediatric injury prevention efforts in Cameroon should target pedestrian RTIs, falls, and burns and consider school-based interventions.

Socioeconomic correlates of trauma: An analysis of emergency ward patients in Yaoundé, Cameroon.

INTRODUCTION: Injury is a significant and increasingly common cause of morbidity and mortality in sub-Saharan Africa; however, the social and economic factors underlying these trends are not well understood. We evaluated the relationship between socioeconomic status (SES) and trauma outcomes using a prospective registry of patients presenting to the largest trauma hospital in Yaoundé, Cameroon. METHODS: Trauma patients (n=2855) presenting to the emergency ward at Central Hospital, Yaoundé between April 15 and October 15, 2009 were surveyed regarding demographic and socioeconomic background, nature and severity of injuries, treatment, and disposition. A wealth score was estimated for each patient, corresponding to an SES index constructed using principle components analysis of the urban Cameroonian Demographic and Health Survey. Logistic regression was used to evaluate the effects of SES on care-seeking behaviour, injury severity, and treatment outcome. MAIN OUTCOME MEASURES: SES wealth score, care-seeking prior to visiting hospital, injury severity, treatment outcome. RESULTS: Patients aged 1-89 presented with road traffic injuries (59.83%), falls (7.76%), and penetrating trauma (6.16%), and had higher SES than the broader urban Cameroonian population. Within the Yaoundé sample, being in the lowest SES quintile was associated with an increased likelihood of having sought care elsewhere before presenting to the hospital (aOR=3.28, p<0.001), after controlling for background and injury characteristics. Patients in the lowest SES quintile were also more likely to present with moderate/severe injuries (aOR=4.93, p<0.001), and were more likely to be transferred to the operating room. CONCLUSIONS: Patients presenting to this trauma centre were wealthier than the broader community, suggesting the possibility of barriers to accessing care. Poorer patients were more likely to have severe injuries and more likely to need surgery, but were less likely to seek care from a major trauma centre immediately. Substantial differences in SES between the sample visiting the hospital and the broader community suggest a need for community-based sampling approaches in future trauma research.

Analysis of prospective trauma registry data in Francophone Africa: a pilot study from Cameroon.

INTRODUCTION: Injury rates in sub-Saharan Africa are among the highest in the world, but prospective, registry-based reports from Cameroon are limited. We aimed to create a prospective trauma registry to expand the data elements collected on injury at a busy tertiary center in Yaoundé Cameroon. METHODS: Details of the injury context, presentation, care, cost, and disposition from the emergency department (ED) were gathered over a 6-month period, by trained research assistants using a structured questionnaire. Bivariate and multivariate models were built to explore variable relationships and outcomes. RESULTS: There were 2,855 injured patients in 6 months, comprising almost half of all ED visits. Mean age was 30 years; 73 % were male. Injury mechanism was road traffic injury in 59 %, fall in 7 %, penetrating trauma in 6 %, and animal bites in 4 %. Of these, 1,974 (69 %) were discharged home, 517 (18 %) taken to the operating room, and 14 (1 %) to the intensive care unit. The body areas most severely injured were pelvis and extremity in 43 %, head in 30 %, chest in 4 %, and abdomen in 3 %. The estimated injury severity score (eISS) was <9 in 60 %, 9-24 in 35 %, and >25 in 2 %. Mortality was 0.7 %. In the multivariate analysis, independent predictors of mortality were eISS ≥9 and Glasgow Coma Score ≤12. Road traffic injury was an independent predictor for the need to have surgery. Trauma registry results were presented to the Ministry of Health in Cameroon, prompting the formation of a National Injury Committee. CONCLUSIONS: Injuries comprise a significant proportion of ED visits and utilization of surgical services in Yaoundé. A prospective approach allows for more extensive information. Thorough data from a prospective trauma registry can be used successfully to advocate for policy towards prevention and treatment of injuries.
