A long walk to freedom: the epidemiology of penetrating trauma in South Africa - analysis of 4 697 patients over a six-year period at Chris Hani Baragwanath Academic Hospital.

BACKGROUND: Despite the city of Johannesburg having one of the highest rates of crime in the world, no national databank for trauma exists. This study profiles the victims of penetrating trauma and identifies geographical areas in which it occurs, while describing the outcomes and patterns of injury. METHODS: A retrospective study including penetrating trauma patients triaged as Priority 1, presenting at the Chris Hani Baragwanath Academic Hospital's (CHBAH) trauma department over a six-year period (2011-2016). RESULTS: A total of 4 697 patients were included. The majority of victims were Black African males (92.1%) between the ages of 29-40 years, and stabbings were the most common mechanism of injury (71.8%), followed by gunshots. The commonest body area affected was the thorax, with a consequent haemothorax the most likely result. Weekends accounted for over 48% of all presentations - the last weekend of the month being the busiest. Region D was the area in Johannesburg with the highest trauma incidence (51.9%), with the oldest townships in Soweto found to be "hot spots". CONCLUSION: Penetrating trauma is inherently linked to alcohol abuse and interpersonal violence in South Africa,1 primarily affecting its young economic, working-class citizens. The data provided some insight into the burden, structure and challenges of our trauma system. These should be regarded as opportunities to implement change and improve our surveillance and prevention, beginning with a national trauma databank.

Surgical site infection after penetrating abdominal trauma with bowel involvement: a comparison between HIV-seropositive and seronegative patients.

BACKGROUND: The influence of HIV-infection on surgical site infection (SSI) after surgery for penetrating abdominal trauma is not investigated and therefore not as yet elucidated. This prospective study was performed with the aim to compare the SSI rate in human immunodeficiency virus (HIV)-seropositive and HIV-negative patients and to identify other risk factors for this abdominal wound complication. METHOD: 98 patients who underwent small or large bowel resection and subsequent anastomosis due to penetrating abdominal trauma were included in the study. Injury related factors as well as demographical and physiological parameters, including HIV-status were analysed and superficial and deep SSI incidence rates were evaluated. RESULTS: Of the 98 patients, 23 patients (23%) were HIV-seropositive. The overall superficial SSI rate was 45% and the deep SSI rate was 15%. No significant difference in SSI (superficial or deep) in the HIV-seropositive and -negative group was demonstrated (superficial SSI HIV-pos vs HIV-neg: 61% vs 40%; p=0.172, deep SSI 22% vs 13%, p=0.276). Multivariate analysis identified five independent risk factors for SSI: postoperative CD4 count < 250 cells/µl, postoperative albumin < 30 g/L, relook operation, anastomotic leak and colonic anastomosis. CONCLUSION: HIV-infection is not an independent risk factor for developing SSI after penetrating abdominal trauma. Low postoperative CD4 count, irrespective of HIV status, low postoperative albumin, relook operation, anastomotic leak and colonic anastomosis are predictors for SSI irrespective of the HIV-serostatus. These factors should be considered in unison during the decision-making process of abdominal wound closure; planned secondary wound treatment or immediate application of negative pressure dressings in patients with a high-risk profile may decrease the hospital stay and the financial burden on the health care system.

Trauma electives in South Africa provide valuable training for international surgeons.

BACKGROUND: Trauma electives in South Africa (SA) are common and many foreign-based surgeons have undertaken such electives over the past 3 decades. Despite this, little academic attention has been paid to these electives, which remain largely informal and unstructured. This project aims to redress this deficit. OBJECTIVES: To investigate and document the extent of trauma clinical electives and to assess their impact on the careers of foreign surgeons who have undertaken such electives. METHODS: A mixed methods-style questionnaire was compiled, which sought to document the demographics of surgeons undertaking an SA trauma clinical elective, the trauma clinical experience they had prior to the elective, as well as the volume of experience they acquired during the elective. RESULTS: Sixty questionnaires were sent out and 21 were completed. There were 16 male and 5 female respondents. Only 17 had undertaken a formal trauma rotation before their elective in SA. The mean number of major resuscitations managed prior to rotating through surgery departments in SA was 15, and the mean number managed during a 12-month rotation in SA was 204. It would take each respondent 14 years in their country of origin to acquire an equivalent level of exposure to major resuscitation. During the year before their elective, each surgeon had been exposed to a mean number of the following: 0.5 gunshot wounds (GSWs), 2 stab wounds (SWs), 0.1 blast injuries and 19 road traffic accidents (RTAs). The equivalent mean number for their year in SA was 106 GSWs, 153 SWs, 4 blast injuries and 123 RTAs. The time necessary to achieve a similar level of exposure to their SA experience if they had remained in their country of origin was 213 years for GSWs, 73 years for SWs, 41 years for blast injuries and 7 years for RTAs. Compared with their SA elective, it would take each respondent 3 years to insert as many central venous lines, 9 years to perform the same number of tube thoracostomies, 9 years to manage as many surgical airways, 18 years to explore as many SWs of the neck and 93 years to explore as many GSWs of the neck. Furthermore, it would take 33 years to see and perform as many laparotomies for SWs to the abdomen, 374 years to perform an equivalent number of GSWs to the abdomen and 34 years of experience to perform as many damage-control laparotomies in their countries of origin. In terms of vascular trauma, it would take 23 years to see as many vascular injuries secondary to SWs and 77 years to see an equivalent number of vascular injuries secondary to GSWs. CONCLUSIONS: A trauma clinical elective in SA provides an unparalleled exposure to almost all forms of trauma in conjunction with a well-developed academic support programme. Formalising these trauma electives might allow for the development of exchange programmes for SA trainees who wish to acquire international exposure to advanced general surgical training.

Trauma care systems in South Africa.

AIM: To provide an overview of the provision of trauma care in South Africa, a middle income country emerging into a democratic state. METHODS: Literature review. CONCLUSIONS: South Africa is gripped by an almost hidden epidemic of intentional and non-intentional injury, largely driven by alcohol and substance abuse, against a background of poverty and rapid urbanisation. Gross inequities exist in the provision of trauma care. Access to pre-hospital care and overloading of tertiary facilities are the major inefficiencies to be addressed. The burden of disease due to trauma presents unique opportunities for reconstruction and clinical research.

Evolving concepts in the management of colonic injury.

PURPOSE: The management of colonic injury has changed in recent years. This study sought to evaluate current surgical management of injuries to the colon in a busy urban trauma centre, in the light of our increasing confidence in primary repair and evolving understanding of the concepts and practice of damage control surgery. METHODS: A retrospective analysis was made of consecutive patients presenting with colonic injury from January 1 to December 31 1998. Patients without full-thickness lesions of the colon were excluded, as were patients who died within 24 h of admission. Demographic data, wounding patterns and clinical course were studied. RESULTS: One hundred twenty-seven patients were analyzed. Management without colostomy was achieved in 84% of cases. Patients who underwent diversion of the faecal stream had increased morbidity and hospital stay compared to equivalent patients who were repaired primarily. The important subgroup of patients who underwent damage control or abbreviated laparotomy is discussed. CONCLUSION: This study further strengthens the validity of direct repair or resection and primary anastomosis for colonic injury. Strategies to deal with the subgroup of patients at very high risk of postoperative complications are suggested.
