Aspects épidémiologiques, diagnostiques et thérapeutiques des traumatismes vertébro-médullaires au Centre Hospitalier Universitaire d'Owendo, Gabon / Spinal cord injury at the Owendo teaching hospital, Gabon. Epidemiology, diagnosis and management

Spinal cord injury constitutes a multidisciplinary therapeutic emergency. It occurs usually in a context of polytrauma. The aim of this study was to describe the management of spinal cord injury admitted to the emergency department of a "trauma center". Methods: This is a prospective observational study carried out at the University Hospital of Owendo, Gabon. Patients admitted to the emergency department of any age for spinal cord injury and having performed a radiological examination were included. Socio-demographic parameters, circumstances and times of onset of trauma, mode of transport, state of consciousness, sensory and motor deficit, American Spinal Injury Association (ASIA) Score, hemodynamic and respiratory status were assessed. Results: During the study period, 850 patients were registered at the emergency department. Among them 112 were admitted for spinal cord injury (3.17%). The average age of the patients was 36 ± 3 years. The male gender accounted for 77% of cases. It concerned in 36% of cases the unemployed. The road accident was incriminated in 61%. Pedestrians were involved in 81% of cases. The clinical evaluation on admission found a sensorimotor deficit in 45 patients (40.17%), there were 11 tetraplegias (10%) and 3 paraplegias (3%). The majority of patients (77.7%) were classified as Fränkel stage A. The lesions were dominated by dislocations of the cervical spine (30.4%). Specialized care was essentially orthopedic in 60.7%. No patient was operated. Conclusion: Spinal cord injuries are "time-dependent" medical and surgical emergencies. A codified organization of pre-hospital care and an efficient "trauma center" are essential factors for the management of this type of traumatic pathology

Major interpersonal violence cases seen in a Pretoria academic hospital over a one-year period, with emphasis on community assault cases

Introduction: Interpersonal violence cases make up a significant portion of the trauma cases seen in emergency centres in South Africa. Community assaults are extremely violent attacks on suspected perpetrators by members of the community aimed at inflicting serious injury. The aim of this study was to profile the major interpersonal violence cases at Kalafong Hospital with emphasis on the community assaults and how this group compares with non- community assaults regarding demographics, surgical intervention and mortality. Methods: A retrospective analysis was conducted of the major interpersonal violence cases seen over a one-year period (1 January 2016 to 31 December 2016) at Kalafong Hospital, Pretoria, South Africa. Data was manually collected and entered into a Microsoft Excel spreadsheet. The Stata 13 statistical program was used for data analysis. Results: During the study period, a total of 578 cases were analysed. Penetrating trauma accounted for 446 (77.2%) cases and blunt trauma for 132 (22.8%) cases. The number of community assault cases was 75 (12.9%). A total of 28 deaths were recorded during this period. Community assaults accounted for 13 (46.4%) of these deaths. Community assault cases had a significantly higher mortality compared to non-community assault cases with 17.3% versus 3%; Odds ratio 6.82 (95% CI 3.04­15.33, p < 0.001). The community assault group also showed a statistically significant difference in the intensive care admission rate with 15.3% compared to 6.9% in the interpersonal violence cases; Odds ratio 2.41 (CI 1.07­5.43, p = 0.028). Conclusion: Community assault cases may present with similar demographics when compared to non-community assault cases, but the difference in disposition and outcome was highlighted in this study with a higher intensive care unit admission rate and a higher mortality rate. A multi-centre follow-up study is recommended to compare demographics across Pretoria and to monitor trends in this subgroup of interpersonal violence cases

Interpretation of emergency CT scans in polytrauma: trauma surgeon vs radiologist

Introduction: Time is critical in the trauma setting. Emergency computed tomography (CT) scans are usually interpreted by the attending doctor and plans to manage the patient are implemented before the formal radiological report is available. This study aims to investigate the discrepancy in interpretation of emergency whole body CT scans in trauma patients by the trauma surgeon and radiologist and to determine if the difference in trauma surgeon and radiologist interpretation of emergency trauma CT scans has an impact on patient management. Method: This prospective observational comparative study was conducted over a 6 month period (01 April­30 September 2016) at the Inkosi Albert Luthuli Central Hospital which has a level 1 trauma department. The study population comprised 62 polytrauma patients who underwent a multiphase whole body CT scans as per the trauma imaging protocol. The trauma surgeons' initial interpretation of the CT scan and radiological report were compared. All CT scans reported by the radiology registrar were reviewed by a consultant radiologist. The time from completion of the CT scan and completion of the radiological report was analysed. Results: Since the trauma surgeon accompanied the patient to radiology and reviewed the images as soon as the scan was complete, the initial interpretation of the CT was performed within 15­30 min. The median time between the CT scan completion and reporting turnaround time was 75 (16­218) min. Critical findings were missed by the trauma surgeon in 4.8% of patients (bronchial transection, abdominal aortic intimal tear and cervical spine fracture) and non-critical/incidental findings in 41.94%. The trauma surgeon correctly detected and graded visceral injury in all cases. Conclusion: There was no significant discrepancy in the critical findings on interpretation of whole body CT scans in polytrauma patients by the trauma surgeon and radiologist and therefore no negative impact on patient management from missed injury or misdiagnosis. The turnaround time for the radiology report does not allow for timeous management of the trauma patient

Cost analysis of violence-related medical imaging in a Free State tertiary trauma unit

Background: Violence is a leading public health problem worldwide. Beyond the pain and suffering, violence has a significant economic impact on a country's health, policing and judicial services. Because of the lack of current and comprehensive data in South Africa, local violence-related economic impact studies are largely estimations. Violence-related imaging expenditure, as a component of a public hospital's expenditure, is yet to be determined. Objectives: The goals of this study were to measure the violence-related patient burden on Pelonomi Tertiary Hospital's (PTH) trauma and radiology services, determine the imaging-component cost of violence-related injuries and calculate the financial burden violence has on the hospital's expenditures. Method: From the PTH's trauma unit patient registry, 1380 patients with violence-related injuries were consecutively sampled for 6 months ending 31 December 2017. Imaging investigations were documented and categorised according to the South African National Department of Health's 2017 Uniform Patient Fee Schedule (UPFS). Descriptive analysis and cost calculations were performed using the 2017 UPFS tariff schedule and hospital-specific health efficiency indicators ­ patient-day equivalent and expenditure per patient-day equivalent. Results: Violence-related injuries accounted for 50.64% of all trauma department visits and received a total of 5475 imaging investigations. Violence-related imaging investigations represented 14.81% of all investigations performed by the radiology department in the study period. Overall violence-related admission costs amounted to R35 410 241.85 (8.33% of the hospital's total expenditure), of which 20.08% (R7 108 845.00) was attributed to imaging investigations. Conclusion: Violence-related admissions had a high patient and financial burden on PTH. The pinnacle of healthcare cost saving is violence prevention; however, the cost-conscious radiologist could assist with cost saving if responsible and ethical imaging practices are followed

A review of blood transfusions in a trauma unit for young children

Background. Trauma is the leading cause of mortality and morbidity worldwide. Blood transfusions play an incremental role in the acute phase, yet practice varies owing to variations in transfusion thresholds and concerns about potential complications, especially in children.Objectives. To evaluate protocol adherence to blood transfusion thresholds in paediatric trauma patients and determine the degree of blood product wastage, as defined by discarded units.Methods. A retrospective, descriptive study of trauma patients (age 0 - 13 years) who received a blood transfusion in the trauma unit at Red Cross War Memorial Children's Hospital, Cape Town, South Africa, over a 5.5-year period (1 January 2009 - 1 July 2014). Haemoglobin (Hb) transfusion thresholds were defined as 10 g/dL for neurotrauma patients and patients requiring skin grafting or a musculocutaneous flap (group 1). All other trauma patients had an Hb transfusion threshold of 7 g/dL (group 2).Results. A total of 144 patients were included (mean age 5.2 years (standard deviation (SD) 3.3), 68.1% male). The mean Hb increase after transfusion was 3.5 g/dL (SD 1.7). Adherence to the transfusion Hb threshold protocol was 96.7% for group 1 v. 34.0% for group 2. No complications were reported. Average blood wastage was 3.5 units per year during the study period.Conclusions. Adherence to paediatric blood transfusion protocol was low in the Hb threshold group <7 g/dL. However, transfusion-related complications and wastage were minimal. Further prospective research is required to determine optimal blood transfusion guidelines for paediatric trauma patients

Analysis of 5 Years of Morbidity and Mortality Conferences in a Metropolitan South African Trauma Service

BACKGROUND:Since 2008 the Pietermaritzburg Metropolitan Trauma Service (PMTS) has run a structured; self-reporting; metropolitan morbidity and mortality conference (MMC). In 2012 a hybrid electronic medical registry (HEMR) was introduced to capture routine data and to generate reports on morbidity and mortality. This paper reviews our experience in setting up a metropolitan MMC and compares the quality of the reported morbidity data from the pre- and post-HEMR era. METHODS:We compared data from the MMC before and after the introduction of the HEMR to audit the impact of these meetings on the reporting and analysis of surgical morbidity and mortality in our service RESULTS:During the 4-year period from 2008 to 2011; a total of 208 MMCs were held. A total of 10 682 patients were admitted by the PMTS during that period; of whom 87% were males; and the mean age was 26 years. Penetrating trauma accounted for 40.9% (4 344/10 628) of the total workload. A total of 432 (4.1%) morbidities were identified. Of these; 36.6% (158) were related to human error; 32% (138/432) were related to surgical pathologies and the remaining 31.9% (136/432) were related to systemic diseases. There was an exponential increase in the reporting of morbidity each year. The total in-hospital mortality was 3% (358/10 682). Following the introduction of the HEMR; from 2012 to 2014; 6 217 patients were admitted. A total of 1 314 (21.1%) adverse events and 315 (5.1%) deaths were recorded by the HEMR. The adverse events were divided into 875 'pathology-related' morbidities and 439 'error-related' morbidities.CONCLUSIONS:The development of the MMC led to increased reporting of morbidity and mortality. The introduction of the HEMR resulted in a dramatic improvement in the capturing of morbidity and mortality data; suggesting that a paper-based self-reporting system tends to underestimate morbidity. Over one-third of all morbidities were related to human error. Common morbidities have been identified
