Insights
Unintentional injuries are a major cause of death for children in low- and middle-income countries. This study in Cameroon found road traffic injuries, particularly among pedestrians, are a significant concern requiring targeted prevention strategies.
Area of Science:
- Pediatric trauma epidemiology
- Global child health
- Injury prevention in low- and middle-income countries (LMICs)
Background:
- Unintentional injury is the leading cause of death for children aged 10-19 years globally.
- Over 95% of injury deaths occur in low- and middle-income countries (LMICs).
- Pediatric injury patterns may differ from adults, necessitating LMIC-specific risk identification.
Purpose of the Study:
- To explore pediatric injury epidemiology and associated costs in Yaoundé, Cameroon.
- To inform targeted injury prevention strategies and resource allocation for child health.
- To identify risks specific to children in LMICs.
Main Methods:
- Retrospective analysis of pediatric (<20 years) trauma patient data from the Central Hospital of Yaoundé emergency department (April-October 2009).
- Utilized univariate, bivariate, and multivariate analyses to examine injury patterns.
- Employed regression analyses to identify predictors of surgical care necessity.
Main Results:
- Children represented 19% of trauma cases, with 54% due to road traffic injuries (RTIs), primarily affecting limbs and pelvis.
- Pedestrians constituted half of RTI victims; taxis/buses were the primary transport for 69.4% of patients, including 71.1% of severely injured individuals.
- 17.9% and 20.8% of patients required major and minor surgery, respectively; higher injury severity scores predicted the need for surgery (p<0.01). Median ED cost was USD 12.71.
Conclusions:
- Pediatric injury is a critical child health issue in Cameroon demanding increased attention and funding.
- Addressing the high burden of pediatric injuries requires policy development, enhanced surgical capacity, and health system strengthening.
- Injury prevention efforts should focus on pedestrian RTIs, falls, and burns, with consideration for school-based interventions.
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.
