Comparative Analysis of Traumatic Deaths in Nigeria

Thoracic trauma in national hospital Abuja, Nigeria: The epidemiology, injury severity and initial management options

Background

Trauma is the leading cause of death in individuals between the ages of 1 and 44 years and it is the third commonest cause of death regardless of age. Thoracic trauma is a relatively common cause of preventable death among trauma patients. The spectrum of injuries after blunt chest trauma presents a challenging problem to the emergency physician. This study is intended to discuss the epidemiology, severity and initial management strategies in chest trauma patients, in a low income country.

Methods

A cross sectional retrospective study among chest trauma patients seen in the emergency room of National Hospital Trauma Centre, Abuja, Nigeria, from January 2015 to December 2017. Relevant patients' information was retrieved from the trauma registry kept in the trauma centre. Data processing and analysis was done using statistical package for social sciences (SPSS) version 24. Test of significance was done where applicable using chi square and student t test, using p value less than 0.05 as significant. Results are presented in tables and figures.

Results

A total of 637 patients, male to female ratio of 3.6 and mean age of 34.18 ± 11.34 were enrolled into the study. The most common mechanisms of injury were MVC (54.6%) and assault (23.5%). Blunt injuries were 3.5 times more frequent than the penetrating injuries. The RTS of 12 (76.3%) and the ISS of 1-15 category (52.3%) were the most common scores. Up to 98% of patients were managed non-operatively. Recovery rate was high (89%) with relatively low mortality rate of 4.2%.

Conclusion

Majority of thoracic trauma can be managed effectively by employing simple, non-operative procedures such as needle decompression and chest tube insertion. Efforts should be made to include these procedures in the skill set of every medical officer working in the emergency room, particularly in low and middle income countries where there is paucity of emergency physicians.

Non-fatal gunshot wounds among military police in Rio de Janeiro: health as a field of emergency against the naturalization of violence

This article discusses health problems due to firearm injuries suffered on duty military police officers in the metropolitan region of Rio de Janeiro (RJ). Medical records analysis was con ducted referring to military police officers who were treated at the Military Police's Central Hos pital (MPCH) due to gunshot wounds from June 2015 to December 2017 according to professional profile, the characteristics of the event and the le sion, the spatial distribution of the incidents in volving gunshot wounds, and the healthcare units involved in their care. Firearms injured four hun dred seventy-five military police officers: 98.3% were male, 77.3% were in service, 97.9% were soldier personnel. As to the anatomical location of the wounds, the most affected regions were: lower (41.1%) and superior (33.1%) limbs, the head neck-face region (23.5%), and thorax-abdomen (3%). The areas in the metropolitan area of Rio de Janeiro with the highest occurrence of firearm morbidity are program areas 3 and 1 and the Baixada Fluminense. There is a correlation between police morbidity rates due to firearm injuries in the municipalities of the metropolitan region and demographic density (p = 0.024).

Perception and Attitude of Surgical Trainees in Nigeria to Trauma Care

Background

Trauma is still the leading cause of death in individuals between the ages of 1 and 44 years. Establishment of good trauma centres and systems has been shown to have a significant positive impact on outcomes. Surgical specialties, particularly trauma, are becoming less attractive in different parts of the world for a variety of reasons.

Aim

 The aim of this study is to ascertain the perception and attitude of future surgeons towards trauma care in Nigeria. Materials and methods. This is a cross-sectional study using a pretested, structured, paper-based questionnaire which was administered to consecutive surgical trainees at the annual revision course of West African College of Surgeons. Data were analyzed using SPSS version 12, and results are presented in tables and figures.

Results

One hundred and fifty-seven questionnaires were adequately completed with a male-to-female ratio of 18 : 1 and median age of 30 years. There is a general agreement among the respondents that trauma incidence in Nigeria is high or very high. While about 70% of the respondents believe that the Nigerian trauma system is poorly planned, about 19% think it is nonexistent. 81 (53.7%) agree or strongly agree that managing trauma patients is too stressful. A good number, 116 (74.4%), strongly agree that having a separate dedicated trauma unit will improve care and outcome. While 82% of the surgical trainees support post fellowship training in trauma, only 62.2% will like to have the training. There is no significant difference between the proportion of males and females who would like to have the training.

Conclusion

Surgical trainees in Nigeria have good perception and positive attitude towards trauma care. Primary prevention measures must be emphasized during surgical trainees' training in trauma.

Ferimentos por arma de fogo em profissionais de segurança pública e militares das forças armadas: revisão integrativa

Resumo Objetivo: sistematizar a produção bibliográfica sobre a ocorrência de ferimentos por arma de fogo (FAF) entre profissionais de segurança pública, incluindo policiais e militares de forças armadas. Métodos: revisão integrativa realizada em bases bibliográficas eletrônicas brasileiras e internacionais (BVS, Scopus, Web of Science e Pubmed), sem estipulação de recorte temporal ou territorial. Resultados: foram encontrados 31 artigos segundo os critérios de inclusão e de exclusão. Notou-se aumento crescente de publicações entre 1976 e 2016, a maioria publicada em inglês, em periódicos da área da saúde. Os FAF foram o principal mecanismo de injúria em serviço entre os policiais, mais frequentes entre profissionais do sexo masculino, na faixa etária de 30 anos. As circunstâncias de maior risco foram: ações de prisão e confrontos com criminosos; respostas a chamados policiais para verificação de perturbação à ordem; e em situações de guerra. Existem poucos estudos que discutam as repercussões físicas dos FAF para o exercício profissional dos trabalhadores de segurança pública.

Road traffic injury in sub-Saharan African countries: A systematic review and summary of observational studies

OBJECTIVE

The aim of this study is to evaluate, through a systematic review of hospital-based studies, the proportion of road traffic injuries and fatalities in sub-Saharan Africa (SSA).

METHODS

In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Meta-analysis of Observational Studies in Epidemiology guidelines, we searched the following electronic databases: PubMed, Embase, Africa-Wide Information, Global Health, and Web of Science. Articles were eligible if they measured proportion of road traffic injuries (RTIs) in SSA by using hospital-based studies. In addition, a reference and citation analysis was conducted as well as a data quality assessment.

RESULTS

Up to 2015, there were a total of 83 hospital-based epidemiologic studies, including 310,660 trauma patients and 99,751 RTI cases, in 13 SSA countries. The median proportion of RTIs among trauma patients was 32% (4 to 91%), of which the median proportion of death for the included articles was 5% (0.3 to 41%).

CONCLUSION

The number of studies evaluating RTI proportions and fatalities in SSA countries is increasing but without the exponential rise expected from World Health Organization calls for research during the Decade of Action for Road Traffic Injuries. Further research infrastructure including standardization of taxonomy, definitions, and data reporting measures, as well as funding, would allow for improved cross-country comparisons.

A cost analysis of road traffic injuries in a tertiary hospital in south-west Nigeria

This study examines the burden of road traffic injuries (RTIs) among road crash victims in a tertiary hospital in Ibadan, Nigeria. The study adopted a purposive sampling method to obtain primary data. Interview was done with 266 RTI victims who were admitted to the University College Hospital, Ibadan and discharged between March and May, 2015, using a structured questionnaire. From the data obtained, the study carried out descriptive statistical analyses. The results showed that the average cost per patient for RTI treatment was ₦ 42,946 ($215.9); on average, the amount expended on surgery was the highest followed by wound dressing and drugs; and the prevalence of catastrophic out-of-pocket (OOP) expenditure was over 86%. It is recommended that given the high burden of OOP hospital expenditure associated with RTI, there is need to implement more effective financial protection mechanisms against the high OOP expenditure faced by crash victims.

Coroner autopsy study of homicides in Rivers State of Nigeria: 11-year review

As most developing countries, including Nigeria, grapple with economic crisis, poor human capital development and high levels of income inequality, violent crimes - especially homicides - continue to be a cause for concern. We studied the pathology and demographic distribution of homicides in Rivers State of Nigeria expecting that the findings would be useful in formulating preventive strategies. Reports of homicide autopsies in the state for 11 years were retrospectively scrutinized for age, gender, type of weapon, site of injury, circumstances, mechanisms and causes of death. The data were analyzed using SPSS version 17. Homicides constituted 50.5% of the medicolegal autopsies. Although the overall male:female ratio was 12.4 : 1, there was variation with weapon. Deaths by firearm had the highest male:female ratio of 24.6 : 1. The mean and peak ages were 29.2 ± 11.4 and 21-30 years, respectively, while the range was 1 to 96 years. Firearms were the most common weapons, at 68.9%, hemorrhagic shock and head injuries at 61.5% and 28.2% respectively were the most common mechanisms and causes of death. Armed robbery incidents were the most common circumstances, while the head was the most common site of injury at 48.8%. The homicide rate is high in our environment and most homicides are committed during armed robberies using firearms. Improving medical care and providing emergency medical services will reduce cases of deaths from homicides, most of which occur due to manageable hemorrhagic shock. Increasing the drive towards controlling illegal arms acquisition and possession will reduce the present carnage in the state.

Pattern of homicide coroner's autopsies at University College Hospital, Ibadan, Nigeria: 1997-2006

There is relatively little information regarding the pattern of homicides in developing countries such as Nigeria. This study is aimed at determining the pattern and demographic factors associated with homicide cases seen in a Nigerian Teaching Hospital. It is a descriptive autopsy study of homicide cases seen at the University College Hospital (UCH), Ibadan over a 10-year period from January 1997 to December 2006. All the coroner's autopsies for the period, of homicides or suspected homicides, were reviewed with emphasis on the following: gender, age, occupation, circumstances surrounding event, likely motive, type of weapon used, site(s) of injury and mechanism of death. Homicides accounted for 153 (3.1%) of the 4928 coroner's cases at the UCH within the study period. One hundred and thirty-seven of the 152 cases were men, and the overall age range was 4-83 years. The mechanism of death was haemorrhagic shock in 91 cases (59.9%); severe raised intracranial pressure in 58 cases (38.2%); septicaemic shock in two cases (1.3%); and asphyxia in one case (0.7%). Gunshot injuries accounted for 64.5% of the fatalities, sharp objects 21.1% and blunt force 14.5%. Most were victims of armed robbery attacks. The head, abdomen, chest and lower limbs were single sites of injuries in descending order of frequency and most of the cases sustained multiple injuries involving two or more of these sites. Gunshot deaths were the commonest form of homicides in the period under review. Young males and victims of armed robbery attacks were most susceptible.

The role of forensic dentist following mass disaster

This review article focuses on mass disaster situations that may arise from natural or manmade circumstances and the significant role of forensic dental personnel in human identification following such occurrences. The various forensic dental modalities of identification that include matching techniques, postmortem profiling, genetic fingerprinting, dental fossil assessment and dental biometrics with digital subtraction were considered.

The varying extent of use of forensic dental techniques and the resulting positive impact on human identification were considered. The importance of preparation by way of special training for forensic dental personnel, mock disaster rehearsal, and use of modern day technology was stressed. The need for international standardization of identification through the use of Interpol Disaster Victim Identification (DVI) for ms was further emphasized.

Recommendations for improved human identification in Nigerian situation include reform of the National Emergency Management Association (NEMA), incorporation of dental care in primary health care to facilitate proper ante mortem database of the populace and commencement of identification at site of disaster.

Blood screening in a southern Nigeria City: a case study with SAVAN

OBJECTIVE

Commercial motorcycle transportation and motorbike riding in Nigeria is prevalent, and road traffic accidents often result. Characteristic of such accidents is massive blood loss, thus exerting extreme pressure on the blood bank for replenishment and screening. The need to galvanize the system to design a blood bank with minimal bureaucracy and easy access led to screening for blood group. A delay in accessing blood for the victims leads to higher mortality.

METHOD

Our approach was to establish a pre-crash blood data for all auto-bike riders who participated in Save Accident Victims Association of Nigeria (SAVAN, an indigenous, nongovernmental organization) training program. Data used were obtained from 1250 auto-bike riders who volunteered at our workshop. Tile grouping method was used for the screening.

RESULTS

Blood group O positive (54.3%) was the most common blood group type among the auto-bike riders studied, with A positive following at 20.3 percent, B positive at 18.8 percent, O negative at 3.7 percent, AB positive at 1.3 percent, B negative at 1.1 percent, and A negative at 0.5 percent. It was observed that none of the volunteers grouped AB negative.

CONCLUSION

Blood group of auto-bike riders, pedestrians, passengers, and all potential victims should be documented in their identification card to facilitate blood transfusion during major crisis or disasters where the facilities for typing are not available.
