IntroductionInjury 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.MethodsTrauma 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 measuresSES wealth score, care-seeking prior to visiting hospital, injury severity, treatment outcome.ResultsPatients 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

Increases in the prevalence of noncommunicable diseases (NCDs), particularly cardiometabolic diseases such as cardiovascular disease, stroke and diabetes, and their major risk factors have not been uniform across settings: for example, cardiovascular disease mortality has declined over recent decades in high-income countries but increased in low- and middle-income countries (LMICs). The factors contributing to this rise are varied and are influenced by environmental, social, political and commercial determinants of health, among other factors. This Review focuses on understanding the rise of cardiometabolic diseases in LMICs, with particular emphasis on obesity and its drivers, together with broader environmental and macro determinants of health, as well as LMIC-based responses to counteract cardiometabolic diseases. The rise of cardiometabolic diseases in low- and middle-income countries is tied to a multitude of environmental, social and commercial determinants, which are discussed in this Review along with a strategy to counteract those factors., Author(s): J.

Most countries, including Botswana, have established Institutional Review Boards (IRBs) to provide oversight of research involving human beings. Although much has been published on the structure and function of IRBs around the world, there is less literature that empirically describes the perspectives of stakeholders in low- and middle-income country (LMIC) settings regarding IRB processes. In this study, we employed primarily quantitative methods to examine the perceptions of researchers at the University of Botswana (UB) about the review of research protocols by local IRBs. Data were collected using a web-based survey (SurveyMonkey). This was a preliminary effort to document some of the emerging experiences of researchers with ethics review in a context where both research and research oversight are relatively new. Findings from 85 researchers indicate that researchers recognized the need for an IRB to review all human research protocols, expressed the need for research ethics training, experienced high rates of approval at government ministries and UB, and generally believed that ethics review processes can help researchers themselves better understand and appreciate research ethics in general. Though only about one-quarter of respondents reported a more positive view of research ethics after interacting with the UB IRB, 56.5 percent reported no change. In contexts where IRBs have recently been established, it can be particularly important to document the perspectives of researchers in order to align expectations with capabilities, and identify areas where IRBs can improve operations. Future efforts to advance research ethics and ethical review in Botswana should include establishing research ethics training requirements and courses for researchers, increasing investment in IRBs and their training, further developing institutional and national research ethics policies, and formalizing agreements between IRBs and others involved in research oversight in the country to support coordinated review.

BackgroundRoad traffic injuries (RTIs) are a major cause of death and disability worldwide. In Cameroon, like the rest of sub-Saharan Africa, more data on RTI patterns and outcomes are needed to improve treatment and prevention. This study analyses RTIs seen in the emergency room of the busiest trauma centre in Yaoundé, Cameroon.MethodsA prospective injury surveillance study was conducted in the emergency room of the Central Hospital of Yaoundé from April 15 to October 15, 2009. RTI patterns and relationships among demographic variables, road collision characteristics, injury severity, and outcomes were identified.ResultsA total of 1686 RTI victims were enrolled. The mean age was 31 years, and 73% were male. Eighty-eight percent of road collisions occurred on paved roads. The most common user categories were 'pedestrian' (34%) and 'motorcyclist' (29%). Pedestrians were more likely to be female (p

IntroductionInjury 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.MethodsDetails 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.ResultsThere 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 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.ConclusionsInjuries 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.

BackgroundIn the developed world, multiple injury severity scores have been used for trauma patient evaluation and study. However, few studies have supported the effectiveness of different trauma scoring methods in the developing world. The Kampala Trauma Score (KTS) was developed for use in resource-limited settings and has been shown to be a robust predictor of death. This study evaluates the ability of KTS to predict the mortality of trauma patients compared to other trauma scoring systems.MethodsData were collected on injured patients presenting to Central Hospital of Yaoundé, Cameroon from April 15 to October 15, 2009. The KTS, Injury Severity Score, Revised Trauma Score, Glasgow Coma Scale, and Trauma Injury Severity Score were calculated for each patient. Scores were evaluated as predictors of mortality using logistic regression models. Areas under receiver operating characteristic (ROC) curves were compared.ResultsAltogether, 2855 patients were evaluated with a mortality rate of 6 per 1000. Each score analyzed was a statistically significant predictor of mortality. The area under the ROC for KTS as a predictor of mortality was 0.7748 (95% CI 0.6285-0.9212). There were no statistically significant pairwise differences between ROC areas of KTS and other scores. Similar results were found when the analysis was limited to severe injuries.ConclusionsThis comparison of KTS to other trauma scores supports the adoption of KTS for injury surveillance and triage in resource-limited settings. We show that the KTS is as effective as other scoring systems for predicting patient mortality.
