Epidemiology of Patients with Head Injury at a Tertiary Hospital in Rwanda.

INTRODUCTION: Traumatic injuries disproportionately affect populations in low and middle-income countries (LMIC) where head injuries predominate. The Rwandan Ministry of Health (MOH) has dramatically improved access to emergency services by rebuilding its health infrastructure. The MOH has strengthened the nation's acute emergency response by renovating emergency departments (ED), developing the field of emergency medicine as a specialty, and establishing a prehospital care service: Service d'Aide Medicale Urgente (SAMU). Despite the prevalence of traumatic injury in LMIC and the evolving emergency service in Rwanda, data regarding head trauma epidemiology is lacking. METHODS: We conducted this retrospective cohort study at the University Teaching Hospital of Kigali (UTH-K) and used a linked prehospital database to investigate the demographics, mechanism, and degree of acute medical interventions amongst prehospital patients with head injury. RESULTS: Of the 2,426 patients transported by SAMU during the study period, 1,669 were found to have traumatic injuries. Data from 945 prehospital patients were accrued, with 534 (56.5%) of these patients diagnosed with a head injury. The median age was 30 years, with most patients being male (80.3%). Motor vehicle collisions accounted for almost 78% of all head injuries. One in six head injuries were due to a pedestrian struck by a vehicle. Emergency department interventions included intubations (6.7%), intravenous fluids (2.4%), and oxygen administration (4.9%). Alcohol use was not evaluated or could not be confirmed in 81.3% of head injury cases. The median length of stay (LOS) in the ED was two days (interquartile range: 1,3). A total of 184 patients were admitted, with 13% requiring craniotomies; their median in-hospital care duration was 13 days. CONCLUSION: In this cohort of Rwandan trauma patients, head injury was most prevalent amongst males and pedestrians. Alcohol use was not evaluated in the majority of patients. These traumatic patterns were predominantly due to road traffic injury, suggesting that interventions addressing the prevention of this mechanism, and treatment of head injury, may be beneficial in the Rwandan setting.

The Initial Prehospital Management of Traumatic Brain Injuries in Kigali, Rwanda.

INTRODUCTION: Traumatic brain injuries (TBIs) are an important cause of mortality and disability around the world. Early intervention and stabilization are necessary to obtain optimal outcomes, yet little is written on the topic in low- and middle-income countries (LMICs). The aim is to provide a descriptive analysis of patients with TBI treated by Service d'Aide Medicale Urgente (SAMU), the prehospital ambulance service in Kigali, Rwanda. HYPOTHESIS/PROBLEM: What is the incidence and nature of TBI seen on the ambulance in Kigali, Rwanda? METHODS: A retrospective descriptive analysis was performed using SAMU records captured on an electronic database from December 2012 through May 2016. Variables included demographic information, injury characteristics, and interventional data. RESULTS: Patients with TBIs accounted for 18.0% (n = 2,012) of all SAMU cases. The incidence of TBIs in Kigali was 234 crashes per 100,000 people. The mean age was 30.5 (SD = 11.5) years and 81.5% (n = 1,615) were men. The most common mechanisms were road traffic incidents (RTIs; 78.5%, n = 1,535), assault (10.7%, n=216), and falls (7.8%, n=156). Most patients experienced mild TBI (Glasgow Coma Score [GCS] ≥ 13; 83.5%, n = 1,625). The most common interventions were provision of pain medications (71.0%, n = 1,429), placement of a cervical collar (53.6%, n = 1,079), and administration of intravenous fluids (48.7%, n = 979). In total, TBIs were involved in 67.0% of all mortalities seen by SAMU. CONCLUSION: Currently, TBIs represent a large burden of disease managed in the prehospital setting of Kigali, Rwanda. These injuries are most often caused by RTIs and were observed in 67% of mortalities seen by SAMU. Rwanda has implemented several initiatives to reduce the incidence of TBIs with a specific emphasis on road safety. Further efforts are needed to better prevent these injuries. Countries seeking to develop prehospital care capacity should train providers to manage patients with TBIs.

Prehospital epidemiology and management of injured children in Kigali, Rwanda.

INTRODUCTION: Paediatric injuries are a major cause of mortality and disability worldwide, yet little information exists regarding its epidemiology or prehospital management in low-income and middle-income countries. We aimed to describe the paediatric injuries seen and managed by the prehospital ambulance service, Service d'Aide Medicale d'Urgence (SAMU), in Kigali, Rwanda over more than 3 years. METHODS: A retrospective, descriptive analysis was conducted of all injured children managed by SAMU in the prehospital setting between December 2012 and April 2016. RESULTS: SAMU responded to a total of 636 injured children, 10% of all patients seen. The incidence of paediatric injury in Kigali, Rwanda was 140 injuries per 100 000 children. 65% were male and the average age 13.5 (±5.3). Most patients were between 15 and 19 years old (56%). The most common causes of injuries were road traffic incidents (RTIs) (447, 72%), falls (70, 11%) and assaults (50, 8%). Most RTIs involved pedestrians (251, 56%), while 15% (65) involved a bicycle. Anatomical injuries included trauma to the head (330, 52%), lower limb (280, 44%) and upper limb (179, 28%). Common interventions included provision of pain medications (445, 70%), intravenous fluids (217, 34%) and stabilisation with cervical collar (190, 30%). CONCLUSION: In Kigali, RTIs were the most frequent cause of injuries to children requiring prehospital response with most RTIs involving pedestrians. Rwanda has recently instituted several programmes to reduce the impact of paediatric injuries especially with regard to RTIs. These include changes in traffic laws and increased road safety initiatives.

Diagnosis and Management of Acute Heart Failure in Sub-Saharan Africa.

PURPOSE OF REVIEW: Acute heart failure (AHF) is a common emergency presentation in Sub-Saharan Africa (SSA). In the current review, we present the most recent data on the epidemiology of AHF in SSA and discuss recommended approaches to management in resource-limited settings, with a particular focus on primary and secondary facilities (e.g., health centers and district hospitals), where these patients often present. RECENT FINDINGS: AHF in SSA is most often due to hypertension, cardiomyopathies, and rheumatic heart disease. The etiology of AHF may be different in rural as compared with urban settings. Diagnostic tools for AHF are often lacking in SSA, especially at the first-level facilities. Point-of-care ultrasound (POCUS) and biomarker tests, such as brain natriuretic peptide (BNP), offer promise in helping to mitigate diagnostic challenges. POCUS can also help distinguish among types of heart failure and prompt the correct treatment strategy. Many of the drugs and equipment commonly used to treat AHF in resource-rich settings are lacking in SSA. However, some adaptations of commonly available materials may provide temporary alternatives. The epidemiology of AHF in SSA differs from that of high-income settings. Management of AHF at the first-level facility in SSA is an important and understudied problem. Simplified diagnostic and treatment algorithms rooted in knowledge of the local epidemiology should be developed and tested as part of broader efforts to combat cardiovascular disease in SSA.
