BACKGROUND: Research on the impact of the US President's Emergency Plan for AIDS Relief (PEPFAR) transition in South Africa (SA) in 2012 found varying results in retention in care (RIC) of people living with HIV (PLWH OBJECTIVES: To investigate the factors that impacted RIC during the PEPFAR transition in Western Cape Province, SA, in 2012 METHODS: We used aggregate data from 61 facilities supported by four non-governmental organisations from 2007 to 2015. The main outcome was RIC 12 months after antiretroviral therapy initiation for two periods - during PEPFAR and post PEPFAR. We used adjusted quantile regression to estimate the effect of the PEPFAR pull-out on RIC RESULTS: Regression models (50th quantile) for 12-month RIC showed a 4.0% (95% CI -7.7 - -0.4%) decline in RIC post-direct service. Facilities supported by Anova/Kheth'impilo fared worst post PEFPAR, with a decline in RIC of -4.9% (95% CI -8.8 - -1.0%), while TB, HIV/AIDS, Treatment Support, and Integrated Therapy (that'sit) fared best (3.6% increase in RIC; 95% CI: -0.2 - 7.3%). There was a decrease in RIC when comparing urban with rural areas (-7.8%; 95% CI -12.8 - -2.9%). City of Cape Town combined with Western Cape Government health facilities showed a substantial decrease (-6.1%; 95% CI -10.6 - -1.7%), while community health clinic (v. central day clinics) declined (-6.4; 95% CI -10.6 - -2.1%) in RIC. We observed no RIC difference by facility size and a slight increase when two or more human resources transitioned from PEPFAR to the government CONCLUSIONS: When PEPFAR funding decreased in 2012, there was a decrease in RIC. To ensure the continuity of HIV care when a major funder withdraws sufficient and stable transition resources, investment in organisations that understand the local context, joint planning and co-ordination are required

BACKGROUND. Hanging is a common form of self-harm, and emergency care physicians will not infrequently be called upon to manage a survivor. Despite the relative frequency of the injury, there is a paucity of literature on the topic and the spectrum and incidence of associated injuries are poorly described.OBJECTIVES. To review experience with management of victims of hanging at a major trauma centre in South Africa.METHODS. All patients treated by the Pietermaritzburg Metropolitan Trauma Service following a hanging incident between December 2012 and December 2018 were identified from the Hybrid Electronic Medical Registry. Basic demographics were recorded, and the management and outcome of each patient were noted.RESULTS. During the 6-year period under review, a total of 154 patients were seen following a hanging incident. The mean age was 29.4 years. There were 24 females (15.6%) and 130 males (84.4%). The vast majority (n=150; 97.5%) had attempted suicide, and only 4 hangings (2.5%) were accidental. A total of 92 patients (60.9%) had consumed alcohol prior to the incident. There were 23 patients with a Glasgow Coma Score (GCS) <9 (severe traumatic brain injury (TBI)), 14 with a GCS of 9 - 12 (moderate TBI) and 117 with a GCS >12 (mild TBI). A total of 7 patients (4.5%) required intensive care unit admission, and 25 (16.2%) required intubation. The following extracranial injuries were documented on computed tomography scans: hyoid bone fractures (n=2), cervical spine fracture (n=10), mandible fracture (n=4) and oesophageal injury (n=1). Intracranial pathology was evident on 27.0% of scans, with the most common finding being global cerebral ischaemia. The mortality rate was 2.5% (4/154).CONCLUSIONS. Hanging is a common mechanism of self-harm. It is associated with significant injuries and mortality. The acute management of hanging should focus on airway protection followed by detailed imaging of the head and neck. Further work must attempt to include mortuary data on hanging.

INTRODUCTION: Discrepancy in outcomes between urban and rural trauma patients is well known. We reviewed our institutional experience with the management of gunshot wounds (GSWs) in the specific setting of car hijacking and focused on clinical outcome between rural and urban patients. METHODS: A retrospective review was conducted at a major trauma centre in South Africa over an 8-year period for all patients who presented with any form of GSWs in car hijacking settings. Specific clinical outcomes were compared between rural and urban patients. RESULTS: A total of 101 patients were included (74% male, mean age 34 years). Fifty-five per cent were injured in rural areas and the remaining 45% (45/101) were in the urban district. Mean time from injury to arrival at our trauma centre was 11 hours for rural and 4 hours for urban patients (p < 0.001). Seventy-six per cent (76/101) sustained GSWs to multiple body regions. Sixty-three of the 101 (62%) patients required one or more operative interventions. In individual logistic regressions adjusted for sex and number of regions injured, rural patients were 9 (95% CI: 1.9-44.4) and 7 (95% CI: 2.124.5) times more likely than urban patients to have morbidities or required admissions to intensive care respectively. The risk of death in rural patients was 36 (95% CI: 4.5-284.6) times higher than that of urban patients. CONCLUSIONS: Patients who sustained GSWs in carjacking incidents that occurred in rural areas are associated with significantly greater morbidity and mortality compared with their urban counterparts. Delay to definitive care is likely to be the significant contributory factor, and improvement in prehospital emergency medical service is likely to be beneficial in improving patient outcome.

BACKGROUND: Humans come into contact and interact with an array of animals in a number of areas and environments. We set out to review our experience with animal-related injuries in Pietermaritzburg, KwaZulu-Natal, South AfricaMETHODS: All patients who sustained an injury secondary to an interaction with an animal in the period December 2012-December 2017 were identified from the Hybrid Electronic Medical Registry (HEMRRESULTS: There were 104 patients in the study sample. The mean age of patients in the study was 32.8 years, with a range from 1 to 76 years old. 75% (n = 78) were male and 25% (n = 26) female. Out of the 104 animal-related injuries, 67 were blunt trauma, 39 penetrating trauma and 3 a combination of blunt and penetrating trauma. The species causing trauma included dogs (53), horses (29), cows (18), buffalo (1), warthog (1), impala (1) and a single goat (1). The median time from injury to hospitalisation was 46.62 hours (range from 0 to 504 hours). Injuries occurred to the head (n = 32), face (n = 9), neck (n = 32), abdomen (n = 22), urogenital system (n = 6), upper limb (n = 39) and lower limb (n = 39). The Injury Severity Score (ISS) mean for the patients was 8.16, the range 1-4, the median 9 and the standard deviation 6.88. In 49 patients the treatment was non-operative. In the remaining 55 patients, a total of 68 operative procedures were required. Operations included wound debridement/surgical washout (n = 38), laparotomy (n = 9), arterial repair/ligation (n = 8), skin graft (n = 4), craniotomy (n = 5), fasciotomy (n = 2), amputation (n = 1), and placement of an ICP monitor (n = 1). 49 of these operations were for patients with dog bite injuries. The mean hospital stay was 0.13 days with a range of 0-4 days. Four patients were admitted to the Intensive Care Unit (ICU) and two patients diedCONCLUSION: Human interactions with animals may result in injuries which require surgical treatment. The most common animal injury is a dog bite but in the case of the larger domestic farm animals, blunt force type injuries and goring can result in significant injuries which require complex surgical interventions

INTRODUCTION: This study examines the nature of trauma laparotomies performed primarily by trainees and those performed under the direct supervision of a consultant. MATERIALS AND METHODS: A retrospective review was undertaken at the Pietermaritzburg Metropolitan Trauma Service (PMTS), South Africa. All patients who underwent a trauma laparotomy were included. Admission physiology, organ injury and outcome were assessed. Statistical comparison using STATA was performed. Chi-squared analysis was used for categorical variables and unpaired T-test for physiology. RESULTS: A total of 562 patients for trauma laparotomy were identified. Ninety percent (506/562) were male and the mean age was 30 years. The in hospital mortality was 7% (40/562). A consultant was present at 35% of cases (197/562). Consultant-lead operations were found to have a higher rate of mortality 16% vs 2% (32/197 vs 8/365: p < 0.001) and ICU 45% vs 25% (89/197 vs 91/365: p < 0.001) than trainee only. Significant differences in many parameters of admission physiology were identified. Consultant-lead procedures had a higher lactate (3.7 vs 2.9: p 0.0043), respiratory rate (RR) (22 vs 20: p 0.0005), heart rate (HR) (102 vs 96: p 0.0035) and a lower systolic blood pressure (SBP) (115 vs 122: p 0.0001) diastolic blood pressure (DBP) (69 vs 73: p 0.0350) pH (7.34 vs 7.36: p 0.0216) base excess (BE, mEq/L) (-4.1 vs -2.5: p 0.0036) and bicarbonate (HCO3, mEq/L) (21.3 vs 22.5: p 0.0043) than trainee only procedures. Consultants were more likely to be called in for a gunshot than a stab wound (p < 0.001). Of the solid organ injuries, consultants are more likely to be called in for cases with liver injury 23% vs 16% (45/197 vs 58/365: p 0.005) and pancreatic injury 15% vs 3% (30/197 vs 11/365: p < 0.001). CONCLUSION: Trainees can safely undertake a subset of trauma laparotomies. However, patients with deranged physiology and complex hepatobiliary injuries should be operated on directly by a consultant.

BACKGROUND. Cerebral gunshot wounds (CGSWs) represent a highly lethal form of traumatic brain injury, and triaging these patients is difficult. The prognostic significance of the serum lactate level in the setting of CGSWs is largely unknown. OBJECTIVES. To examine the relationship between elevated serum lactate levels and mortality in patients with isolated CGSWs. METHODS. A retrospective review of the regional trauma registry was undertaken at the Pietermaritzburg Metropolitan Trauma Service, South Africa, over a 5-year period from 1 January 2010 to 31 December 2014. All patients with an isolated CGSW were included. RESULTS. A total of 102 patients with isolated CGSWs were identified. Of these, 92.2% (94/102) were male. The mean age (standard deviation) was 29 (8) years, and the in-hospital mortality rate was 21.6% (22/102). The mean serum lactate level was significantly higher among non-survivors than among survivors (6.1 mmol/L v. 1.3 mmol/L; p<0.001). Lactate levels among non-survivors were <2 mmol/L in 4.5%, 2 - 3.99 mmol/L in 9.1%, 4 - 5.99 mmol/L in 36.4% and >6 mmol/L in 50.0%. The odds ratio for mortality with a lactate level of 4 -5.99 mmol/L was 67 (95% confidence interval (CI) 1.7 - 2 674.2), while for a lactate level of >6 mmol/L it was 1 787 (95% CI 9.0 - 354 116.1). The serum lactate level accurately predicted mortality even after adjustment for other variables. Based on a receiver operating curve analysis, an optimal cut-off of 3.3 mmol/L for serum lactate as a predictor for mortality was identified (area under the curve = 0.957). CONCLUSIONS. CGSWs are associated with significant mortality, and a raised serum lactate level appears to be an independent predictor of in-hospital mortality. It is a potentially useful adjunct in the resuscitation room for identifying patients with a very poor prognosis.

BACKGROUND: The optimal management of resources within South African state hospitals has been hampered by a paucity of data due to a lack of robust auditing information systems. This study reviews the use of a Hybrid Electronic Medical Record (HEMR) system to capture and aggregate data pertaining to the inpatient service demands on a South African tertiary surgical service. This dataset was used to analyse the appropriateness of tertiary surgical resource utilisation. METHODS: The HEMR system was implemented at Greys Hospital, in the city of Pietermaritzburg, Kwa-Zulu Natal, South Africa on 1 January 2013. Inpatient data pertaining to surgical admissions and operative interventions were captured prospectively. Following an 18-month study period, the data were extracted, aggregated and analysed. The district referral hospitals were mapped, and district surgical procedures performed within the tertiary center were identified and quantified. RESULTS: 7314 patients were admitted and managed by the tertiary surgical service during the study period. The median patient age was 33 years (IQR 6.5-42.4 years). 59.7% were male and 40.3% were female. General, trauma and paediatric surgical admissions constituted 54.8%, 28.6% and 16.6% respectively. Emergency admissions constituted 62.4% and elective admissions 37.6%. Referral sources were captured for 6653 (91%) of the cohort. 4338 (65.2%) patients were referred from district hospitals. The district hospital (Northdale) closest to Greys Hospital was responsible for 1675 (25.2%) of surgical referrals. 4174 operative procedures were performed during the study period, 54.7% performed as an emergency, 34.1% electively and 11.2% semi-electively. The median waiting time for emergency operative intervention was 535 minutes (IQR 130-663). A total of 1272 (30.5%) operative procedures performed were assessed as district-level operations. The time intervals of 07:00-07:59 and 17:00-17:59 were identified as the time periods during which the least number of emergency procedures were performed in the operating theatres. CONCLUSION: The HEMR system enabled the Pietermaritzburg Metropolitan Department of Surgery to quantify the burden of surgical disease and map district referral patterns. Thirty percent of operative procedures performed were assessed as district-level operations. Potentially correctable deficits identified within the tertiary center were lengthy delays to emergency surgery and non-optimal theatre utilisation periods.

BACKGROUND: Trauma is a leading cause of death in the developing world. Blunt thoracic trauma represents a major burden of disease in both adults and children. Few studies have investigated the differences between these two patient groups.OBJECTIVE: To compare mechanism of injury, presentation, management and outcome in children and adults with blunt thoracic trauma.METHODS: Patients were identified from the database of the trauma intensive care unit at Inkosi Albert Luthuli Central Hospital, Durban, South Africa. Demographics and relevant data were extracted from a pre-existing database.RESULTS: Of 415 patients admitted to the unit, 331 (79.7%) were adults and 84 (20.2%) children aged <18 years. The median injury severity score (ISS) was similar for both age groups (32 v. 34; p=0.812). Adults had a higher lactate level at presentation (3.94 v. 2.60 mmol/L; p=0.001). Of the children, 96.4% were injured in motor vehicle collisions, 75.0% as pedestrians. Compared with adults, children had significantly fewer rib fractures (20.2% v. 42.0%; p<0.001), flail chests (2.4% v. 26.3%; p<0.001) and blunt cardiac injuries (BCIs) (9.5% v. 23.6%; p=0.004), but sustained more lung contusions (79.8% v. 65.6%; p=0.013). Mortality in children was significantly lower than in adults (16.7% v. 27.8%; p=0.037).CONCLUSION: Thoracic injuries in children are the result of pedestrian collisions more often than in adults. They suffer fewer rib fractures and BCIs, but more lung contusions. Despite similar ISSs, children have significantly lower mortality than adults. More effort needs to be concentrated on child safety and preventing pedestrian injury.

BACKGROUND: Several authors have suggested that the traditional surgical morbidity and mortality meeting be developed as a tool to identify surgical errors and turn them into learning opportunities for staff. We report our experience with these meetings. METHODS: A structured template was developed for each morbidity and mortality meeting. We used a grid to analyse mortality and classify the death as: (i) death expected/death unexpected; and (ii) death unpreventable/death preventable. Individual cases were then analysed using a combination of error taxonomies. RESULTS: During the period June - December 2011, a total of 400 acute admissions (195 trauma and 205 non-trauma) were managed at Edendale Hospital, Pietermaritzburg, South Africa. During this period, 20 morbidity and mortality meetings were held, at which 30 patients were discussed. There were 10 deaths, of which 5 were unexpected and potentially avoidable. A total of 43 errors were recognised, all in the domain of the acute admissions ward. There were 33 assessment failures, 5 logistical failures, 5 resuscitation failures, 16 errors of execution and 27 errors of planning. Seven patients experienced a number of errors, of whom 5 died. CONCLUSION: Error theory successfully dissected out the contribution of error to adverse events in our institution. Translating this insight into effective strategies to reduce the incidence of error remains a challenge. Using the examples of error identified at the meetings as educational cases may help with initiatives that directly target human error in trauma care.

OBJECTIVE: To develop two practical methods for measuring the affordability of medicines in developing countries. METHODS: The proposed methods - catastrophic and impoverishment methods - rely on easily accessible aggregated expenditure data and take into account a country's income distribution and absolute level of income. The catastrophic method quantifies the proportion of the population whose resources would be catastrophically reduced by spending on a given medicine; the impoverishment method estimates the proportion of the population that would be pushed below the poverty line by procuring a given medicine. These methods are illustrated by calculating the affordability of glibenclamide, an antidiabetic drug, in India and Indonesia. The results were validated by comparing them with the results obtained by using household micro data for India and Indonesia. FINDINGS: When accurate aggregate data are available, the proposed methods offer a practical way to obtain informative and accurate estimates of affordability. Their results are very similar to those obtained with household micro data analysis and are easily compared across countries. CONCLUSION: The catastrophic and impoverishment methods, based on macro data, can provide a suitable estimate of medicine affordability when the household level micro data needed to carry out more sophisticated studies are not available. Their usefulness depends on the availability of accurate aggregated data.

OBJETIVO: Desarrollar dos métodos prácticos para medir la asequibilidad de los medicamentos en los países en vías de desarrollo. MÉTODOS: Los métodos propuestos (métodos para medir los gastos catastróficos y el empobrecimiento) se basan en unos datos agregados fácilmente accesibles sobre el gasto y tienen en cuenta tanto la distribución de los ingresos del país como el nivel absoluto de ingresos. El método de gasto catastrófico cuantifica la proporción de la población cuyos recursos se verían reducidos de manera catastrófica si tuvieran que adquirir un medicamento determinado. El método del empobrecimiento calcula la proporción de la población que pasaría a encontrarse por debajo del umbral de la pobreza si comprara un medicamento determinado. Estos métodos se demuestran calculando la asequibilidad de la glibenclamida, un medicamento antidiabético, en India e Indonesia. Los resultados se refrendaron mediante su comparación con los resultados obtenidos empleando los microdatos para India e Indonesia. RESULTADOS: Cuando se dispone de datos agregados precisos, los métodos propuestos constituyen una forma práctica de obtener evaluaciones informativas y precisas sobre la asequibilidad. Sus resultados son muy similares a los obtenidos mediante los análisis de microdatos nacionales y resultan fáciles de comparar entre los diversos países. CONCLUSIÓN: Los métodos de gasto catastrófico y de empobrecimiento basados en macrodatos pueden ofrecer una evaluación adecuada de la asequibilidad de un medicamento cuando no se dispone de los microdatos necesarios a nivel nacional para desarrollar estudios más complejos. Su utilidad depende de la disponibilidad de unos datos agregados precisos.

OBJECTIF: Développer deux méthodes pratiques permettant de mesurer l'abordabilité des médicaments dans les pays en voie de développement. MÉTHODES: Les méthodes proposées (la méthode catastrophique et la méthode de l'appauvrissement) reposent sur des données de dépenses agrégées facilement accessibles et prennent en compte la répartition des revenus d'un pays ainsi que le niveau de revenu absolu. La méthode catastrophique quantifie la proportion de la population dont les ressources seraient réduites de manière catastrophique par une dépense pour un médicament donné. La méthode de l'appauvrissement estime la proportion de la population qui passerait sous le seuil de pauvreté en achetant un médicament donné. Ces méthodes sont illustrées par le calcul de l'abordabilité de la glibenclamide, un médicament antidiabétique, en Inde et en Indonésie. RÉSULTATS: Lorsque des données agrégées précises sont disponibles, les méthodes proposées offrent un moyen pratique d'obtenir des estimations informatives et précises sur l'abordabilité. Leurs résultats sont très similaires à ceux obtenus par l'analyse des micro-données des ménages et sont facilement comparables d'un pays à l'autre. CONCLUSION: La méthode catastrophique et la méthode de l'appauvrissement, basées sur les macro-données, peuvent offrir une estimation convenable de l'abordabilité des médicaments lorsque les micro-données des ménages nécessaires à des études plus poussées ne sont pas disponibles. Leur utilité dépend de la disponibilité de données agrégées précises.
