- Abstract
Objective: This study examined the trade-offs low-resource setting community members were willing to make in regard to out-of-hospital cardiac arrest care using a discrete choice experiment survey., Methods: We administered a discrete choice experiment survey to a sample of community members 18 years or older across South Africa between April and May 2022. Participants were presented with 18 paired choice tasks comprised of 5 attributes (distance to closest adequate facility, provider of care, response time, chances of survival, and transport cost) and a range of 3 to 5 levels. We used mixed logit models to evaluate respondents' preferences for selected attributes., Results: Analyses were based on 2228 responses and 40 104 choice tasks. Patients valued care with the shortest response time, delivered by the highest qualified individuals, which placed them within the shortest distance of an adequate facility, gave them the highest chance of survival, and costed the least. In addition, patients preferred care delivered by their family members over care delivered by the lay public. The highest mean willingness-to-pay for increased survival is 11 699 South African rand (ZAR), followed by distance to health facility (8108 ZAR), and response time (5678 ZAR), and the lowest for increasing specialization of provider (1287 ZAR)., Conclusions: In low-resource settings, it may align with patients' preference to include targeted resuscitation training for family members of individuals with high-risk for cardiac arrest as a part of out-of-hospital cardiac arrest intervention strategies., Competing Interests: Author Disclosures Author disclosure forms can be accessed below in the Supplemental Material section., (Copyright © 2024 International Society for Health Economics and Outcomes Research.

- Abstract
Background: To limit virus spread during the COVID pandemic, extensive measures were implemented around the world. In South Africa, these restrictions included alcohol and movement restrictions, factors previously linked to injury burden in the country. Consequently, reports from many countries, including South Africa, have shown a reduction in trauma presentations related to these restrictions. However, only few studies and none from Africa focus on the impact of the pandemic restrictions on the Emergency Medical System (EMS)., Methods: We present a retrospective, observational longitudinal study including data from all ambulance transports of physical trauma cases collected during the period 2019-01-01 and 2021-02-28 from the Western Cape Government EMS in the Western Cape Province, South Africa (87,167 cases). Within this timeframe, the 35-days strictest lockdown level period was compared to a 35-days period prior to the lockdown and to the same 35-days period in 2019. Injury characteristics (intent, mechanism, and severity) and time were studied in detail. Ambulance transport volumes as well as ambulance response and on-scene time before and during the pandemic were compared. Significance between indicated periods was determined using Chi-square test., Results: During the strictest lockdown period, presentations of trauma cases declined by > 50%. Ambulance transport volumes decreased for all injury mechanisms and proportions changed. The share of assaults and traffic injuries decreased by 6% and 8%, respectively, while accidental injuries increased by 5%. The proportion of self-inflicted injuries increased by 5%. Studies of injury time showed an increased share of injuries during day shift and a reduction of total injury volume during the weekend during the lockdown. Median response- and on-scene time remained stable in the time-periods studied., Conclusion: This is one of the first reports on the influence of COVID-19 related restrictions on EMS, and the first in South Africa. We report a decline in trauma related ambulance transport volumes in the Western Cape Province as well as changes in injury patterns, largely corresponding to previous findings from hospital settings in South Africa. The unchanged response and on-scene times indicate a well-functioning EMS despite pandemic challenges. More studies are needed, especially disaggregating the different restrictions., (© 2023.

- Abstract
Background: Emergency Departments serve as a main entry point for patients into hospitals, and the team, the core of which is formed by doctors and nurses needs to make sense of and respond to the constant flux of information. This requires sense-making, communication, and collaborative operational decision-making. The study's main aim was to explore how collective, interprofessional sense-making occurs in the emergency department. Collective sense-making is deemed a precursor for adaptive capability, which, in turn, promotes coping in a dynamically changing environment., Method: Doctors and nurses working in five large state emergency departments in Cape Town, South Africa, were invited to participate. Using the SenseMaker® tool, a total of 84 stories were captured over eight weeks between June and August 2018. Doctors and nurses were equally represented. Once participants shared their stories, they self-analysed these stories within a specially designed framework. The stories and self-codified data were analysed separately. Each self-codified data point was plotted in R-studio and inspected for patterns, after which the patterns were further explored. The stories were analysed using content analysis. The SenseMaker® software allows switching between quantitative (signifier) and qualitative (descriptive story) data during interpretation, enabling more deeply nuanced analyses., Results: The results focused on four aspects of sense-making, namely views on the availability of information, the consequences of decisions (actions), assumptions regarding appropriate action, and preferred communication methods. There was a noticeable difference in what doctors and nurses felt would constitute appropriate action. The nurses were more likely to act according to rules and policies, whereas the doctors were more likely to act according to the situation. More than half of the doctors indicated that they found it best to communicate informally, whereas the nurses indicated that formal communication worked best for them., Conclusion: This study was the first to explore the ED's interprofessional team's adaptive capability to respond to situations from a sense-making perspective. We found an operational disconnect between doctors and nurses caused by asymmetric information, disjointed decision-making approaches, differences in habitual communication styles, and a lack of shared feedback loops. By cultivating their varied sense-making experiences into one integrated operational foundation with stronger feedback loops, interprofessional teams' adaptive capability and operational effectiveness in Cape Town EDs can be improved., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Cunningham et al.

- Abstract
Background: Deaths due to injuries exceed 4.4 million annually, with over 90% occurring in low-and middle-income countries. A key contributor to high trauma mortality is prolonged trauma-to-treatment time. Earlier receipt of medical care following an injury is critical to better patient outcomes. Trauma epidemiological studies can identify gaps and opportunities to help strengthen emergency care systems globally, especially in lower income countries, and among military personnel wounded in combat. This paper describes the methodology of the "Epidemiology and Outcomes of Prolonged Trauma Care (EpiC)" study, which aims to investigate how the delivery of resuscitative interventions and their timeliness impacts the morbidity and mortality outcomes of patients with critical injuries in South Africa., Methods: The EpiC study is a prospective, multicenter cohort study that will be implemented over a 6-year period in the Western Cape, South Africa. Data collected will link pre- and in-hospital care with mortuary reports through standardized clinical chart abstraction and will provide longitudinal documentation of the patient's clinical course after injury. The study will enroll an anticipated sample of 14,400 injured adults. Survival and regression analysis will be used to assess the effects of critical early resuscitative interventions (airway, breathing, circulatory, and neurologic) and trauma-to-treatment time on the primary 7-day mortality outcome and secondary mortality (24-h, 30-day) and morbidity outcomes (need for operative interventions, secondary infections, and organ failure)., Discussion: This study is the first effort in the Western Cape of South Africa to build a standardized, high-quality, multicenter epidemiologic trauma dataset that links pre- and in-hospital care with mortuary data. In high-income countries and the U.S. military, the introduction of trauma databases and registries has led to interventions that significantly reduce post-injury death and disability. The EpiC study will describe epidemiology trends over time, and it will enable assessments of how trauma care and system processes directly impact trauma outcomes to ultimately improve the overall emergency care system., Trial Registration: Not applicable as this study is not a clinical trial., (© 2022.

- Abstract
Objectives: While prospective epidemiological data for out-of-hospital cardiac arrest (OHCA) exists in many high-income settings, there is a dearth of such data for the African continent. The aim of this study was to describe OHCA in the Cape Town metropole, South Africa., Design: Observational study with a retrospective descriptive design., Setting: Cape Town metropole, Western Cape province, South Africa., Participants: All patients with OHCA for the period 1 January 2018-31 December 2018 were extracted from public and private emergency medical services (EMS) and described., Outcome Measures: Description of patients with OHCA in terms of demographics, treatment and short-term outcome., Results: A total of 929 patients with OHCA received an EMS response in the Cape Town metropole, corresponding to an annual prevalence of 23.2 per 100 000 persons. Most patients were adult (n=885; 96.5%) and male (n=526; 56.6%) with a median (IQR) age of 63 (26) years. The majority of cardiac arrests occurred in private residences (n=740; 79.7%) and presented with asystole (n=322; 34.6%). EMS resuscitation was only attempted in 7.4% (n=69) of cases and return of spontaneous circulation (ROSC) occurred in 1.3% (n=13) of cases. Almost all patients (n=909; 97.8%) were declared dead on the scene., Conclusion: To our knowledge, this was the largest study investigating OHCA ever undertaken in Africa. We found that while the incidence of OHCA in Cape Town was similar to the literature, resuscitation is attempted in very few patients and ROSC-rates are negligible. This may be as a consequence of protracted response times, poor patient prognosis or an underdeveloped and under-resourced Chain of Survival in low- to middle-income countries, like South Africa. The development of contextual guidelines given resources and disease burden is essential., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

- Abstract
Digital technologies continue to penetrate the South African (SA) healthcare sector at an increasing rate. Clinician-to-clinician diagnostic and management assistance through mHealth is expanding rapidly, reducing professional isolation and unnecessary referrals, and promoting better patient outcomes and more equitable healthcare systems. However, the widespread uptake of mHealth use raises ethical concerns around patient autonomy and safety, and guidance for healthcare workers around the ethical use of mHealth is needed. This article presents the results of a multi-stakeholder workshop at which the 'dos and don'ts' pertaining to mHealth ethics in the SA context were formulated and aligned to seven basic recommendations derived from the literature and previous multi-stakeholder, multi-country meetings.

- Abstract
Background: The South African Triage Scale (SATS) is a validated in-hospital triage tool that has been innovatively adopted for use in the prehospital setting by Western Cape Government (WCG) Emergency Medical Services (EMS) in South Africa. The performance of SATS by EMS providers has not been formally assessed. The study sought to assess the validity and reliability of SATS when used by WCG EMS prehospital providers for single-patient triage., Methods: This is a prospective, assessment-based validation study among WCG EMS providers from March to September 2017 in Cape Town, South Africa. Participants completed an assessment containing 50 clinical vignettes by calculating the three components - triage early warning score (TEWS), discriminators (pre-defined clinical conditions), and a final SATS triage color. Responses were scored against gold standard answers. Validity was assessed by calculating over- and under-triage rates compared to gold standard. Inter-rater reliability was assessed by calculating agreement among EMS providers' responses., Results: A total of 102 EMS providers completed the assessment. The final SATS triage color was accurately determined in 56.5%, under-triaged in 29.5%, and over-triaged in 13.1% of vignette responses. TEWS was calculated correctly in 42.6% of vignettes, under-calculated in 45.0% and over-calculated in 10.9%. Discriminators were correctly identified in only 58.8% of vignettes. There was substantial inter-rater and gold standard agreement for both the TEWS component and final SATS color, but there was lower inter-rater agreement for clinical discriminators., Conclusion: This is the first assessment of SATS as used by EMS providers for prehospital triage. We found that SATS generally under-performed as a triage tool, mainly due to the clinical discriminators. We found good inter-rater reliability, but poor validity. The under-triage rate of 30% was higher than previous reports from the in-hospital setting. The over-triage rate of 13% was acceptable. Further clinically-based and qualitative studies are needed., Trial Registration: Not applicable.

- Abstract
Introduction: Triage - the sorting of patients according to urgency of need for clinical care - is an essential part of delivering effective and efficient emergency care. But when frequent over- or under-triaging occurs, finite time and resources are diverted away from those in greatest need of care and the entire Emergency Medical Services (EMS) system is strained. In resource-constrained settings, such as South Africa, poor triage in EMS only serves to compound other contextual challenges. This study examined the accuracy of dispatcher triage over a one-year period in the Western Cape Government (WCG) EMS system in South Africa., Methods: A retrospective analysis of existing dispatch and EMS data to assess the accuracy of dispatch-assigned priorities was conducted. The mismatch between dispatcher-assigned call priority and triage levels determined by EMS personnel was analyzed via over- and under-triage rates, sensitivity and specificity, and positive and negative predictive values (PPVs and NPVs, respectively)., Results: A total of 185,166 records from December 2016 through November 2017 were analyzed. Across all dispatch complaints, the over-triage rate was 67.6% (95% CI, 66.34-68.76) and the under-triage rate was 16.2% (95% CI, 15.44-16.90). Dispatch triage sensitivity for all included records was 49.2% (95% CI, 48.10-50.38), specificity 71.9% (95% CI, 71.00-72.92), PPV 32.5% (95% CI, 30.02-34.88), and NPV 83.8% (95% CI, 81.93-85.73)., Conclusion: This study provides the first evaluation of dispatch triage accuracy in the WCG EMS system, identifying that the system is suffering from both under- and over-triage. Despite variance across dispatch complaints, both under- and over-triage remained higher than widely accepted norms, and all rates were significantly above acceptable target metrics described in similar studies. Results of this study will be used to motivate the development of more rigorous training programs and resources for WCG EMS dispatchers, including improved dispatch protocols for conditions suffering from high over- and under-triage.

- Abstract
Objectives: In 2010, South Africa (SA) hosted the Fédération Internationale de Football Association (FIFA) World Cup (soccer). Emergency Medical Services (EMS) used the SA mass gathering medicine (MGM) resource model to predict resource allocation. This study analyzed data from the World Cup and compared them with the resource allocation predicted by the SA mass gathering model., Methods: Prospectively, data were collected from patient contacts at 9 venues across the Western Cape province of South Africa. Required resources were based on the number of patients seeking basic life support (BLS), intermediate life support (ILS), and advanced life support (ALS). Overall patient presentation rates (PPRs) and transport to hospital rates (TTHRs) were also calculated., Results: BLS services were required for 78.4% (n = 1279) of patients and were consistently overestimated using the SA mass gathering model. ILS services were required for 14.0% (n = 228), and ALS services were required for 3.1% (n = 51) of patients. Both ILS and ALS services, and TTHR were underestimated at smaller venues., Conclusions: The MGM predictive model overestimated BLS requirements and inconsistently predicted ILS and ALS requirements. MGM resource models, which are heavily based on predicted attendance levels, have inherent limitations, which may be improved by using research-based outcomes.

- Abstract
Objective: Little is known concerning the factors associated with in-hospital mortality of trauma patients in resource-constrained settings, not least in burns centres. We investigated this question in the adult burns centre at Tygerberg Hospital in Cape Town. We further assessed whether the Abbreviated Burn Severity Index (ABSI) is an accurate predictive score of mortality in this setting., Methods: Medical records of all patients admitted with fresh burns over a two-year period (2015 and 2016) were scrutinized to obtain data on patient, injury and admission-related characteristics. Association with in-hospital mortality was investigated for flame burns using logistic regressions and expressed as odds ratios (ORs). The mortality prediction of the ABSI score was assessed using sensitivity and specificity analyses., Results: Overall the in-hospital mortality was 20.4%. For the 263 flame burns, while crude ORs suggested gender, burn depth, burn size, inhalation injury, and referral status were all individually significantly associated with mortality, only the association with female gender, not being referred and burn size remained significant after adjustments (adjusted ORs = 3.79, 2.86 and 1.11 (per percentage increase in size) respectively). For the ABSI score, sensitivity and specificity were 84% and 86% respectively., Conclusion: In this specialised centre, mortality occurs in one in five patients. It is associated with a few clinical parameters, and can be predicted using the ABSI score., (Copyright © 2019 The Authors. Published by Elsevier Ltd.. All rights reserved.)

- Abstract
Introduction: Triage is a key principle in the effective management of major incidents. The process currently relies on algorithms assigning patients to specific triage categories; there is, however, little guidance as to what these categories represent. Previously, these algorithms were validated against injury severity scores, but it is accepted now that the need for life-saving intervention is a more important outcome. However, the definition of a life-saving intervention is unclear. The aim of this study was to define what constitutes a life-saving intervention, in order to facilitate the definition of an adult priority one patient during the definitive care phase of a major incident., Methods: We conducted a modified Delphi study, using a panel of subject matter experts drawn from the United Kingdom and Republic of South Africa with a background in Emergency Care or Major Incident Management. The study was conducted using an online survey tool, over three rounds between July and December 2013. A four point Likert scale was used to seek consensus for 50 possible interventions, with a consensus level set at 70%., Results: 24 participants completed all three rounds of the Delphi, with 32 life-saving interventions reaching consensus., Conclusions: This study provides a consensus definition of what constitutes a life-saving intervention in the context of an adult, priority one patient during the definitive care phase of a major incident. The definition will contribute to further research into major incident triage, specifically in terms of validation of an adult major incident triage tool., (Copyright © 2016 Elsevier Ltd.

- Abstract
Purpose: Understanding caregivers' experiences of care can identify barriers to timely and good quality care, and support the improvement of services. We aimed to explore caregivers' experiences and perceptions of pathways to care, from first access through various levels of health service, for seriously ill and injured children in Cape Town, South Africa, in order to identify areas for improvement., Methods: Semi-structured, qualitative interviews were conducted with primary caregivers of children who were admitted to paediatric intensive care or died in the health system prior to intensive care admission. Interviews explored caregivers' experiences from when their child first became ill, through each level of health care to paediatric intensive care or death. A maximum variation sample of transcripts was purposively sampled from a larger cohort study based on demographic characteristics, child diagnosis, and outcome at 30 days; and analysed using the method of constant comparison., Results: Of the 282 caregivers who were interviewed in the larger cohort study, 45 interviews were included in this qualitative analysis. Some caregivers employed 'tactics' to gain quicker access to care, including bypassing lower levels of care, and negotiating or demanding to see a healthcare professional ahead of other patients. It was sometimes unclear how to access emergency care within facilities; and non-medical personnel informally judged illness severity and helped or hindered quicker access. Caregivers commonly misconceived ambulances to be slow to arrive, and were concerned when ambulance transfers were seemingly not prioritised by illness severity. Communication was often good, but some caregivers experienced language difficulties and/or criticism., Conclusions: Interventions to improve child health care could be based on: reorganising the reception of seriously ill children and making the emergency route within healthcare facilities clear; promoting caregivers' use of ambulances and prioritising transfers according to illness severity; addressing language barriers, and emphasising the importance of effective communication to healthcare providers.

- Abstract
Background: Patients with first-onset seizures commonly present to emergency centres (ECs). The differential diagnosis is broad, potentially life-threatening conditions need to be excluded, and these patients need to be correctly diagnosed and appropriately referred. There are currently no data on adults presenting with first-onset seizures to ECs in South Africa., Objective: To review which investigations were performed on adults presenting with first-onset seizures to six ECs in the Western Cape Province., Methods: A prospective, cross-sectional study was conducted from 1 July 2011 to 31 December 2011. All adults with first-onset seizures were included; children and trauma patients were excluded. Subgroup analyses were conducted regarding HIV status and inter-facility variation., Results: A total of 309 patients were included. Computed tomography (CT) scans were planned in 218 (70.6%) patients, but only performed in 169; 96 (56.8%) showed abnormalities judged to be causative (infarction, intracerebral haemorrhage and atrophy being the most common). At least 80% of patients (n=247) received a full renal and electrolyte screen, blood glucose testing and a full haematological screen. Lumbar puncture (LP) was performed in 67 (21.7%) patients, with normal cerebrospinal fluid findings in 51 (76.1%). Only 27 (8%) patients had an electroencephalogram, of which 5 (18%) were abnormal. There was a statistically significant difference in the number of CT scans (p=0.002) and LPs (p<0.001) performed in the HIV-positive group (n=49)., Conclusion: This study demonstrated inconsistency and wide local variance for all types of investigations done. It emphasises the need for a local guideline to direct doctors to appropriate investigations, ensuring better quality patient care and potential cost-saving.

- Abstract
Community members in developing areas can effectively learn first responder training, and skill decay afterwards is not continuous. It is critical that training be done in the trainees' primary language, even if they speak other languages fluently. Making first responder training obligatory for employees and students may be an effective way to generate first responders.

- Abstract
Introduction: A modified Medical Resource Model to predict the medical resources required at mass gatherings based on the risk profile of events has been developed. This study was undertaken to validate this tool using data from events held in both a developed and a developing country., Methods: A retrospective study was conducted utilizing prospectively gathered data from individual events at Old Trafford Stadium in Manchester, United Kingdom, and Ellis Park Stadium, Johannesburg, South Africa. Both stadia are similar in design and spectator capacity. Data for Professional Football as well as Rugby League and Rugby Union (respectively) matches were used for the study. The medical resources predicted for the events were determined by entering the risk profile of each of the events into the Medical Resource Model. A recently developed South African tool was used to predetermine medical staffing for mass gatherings. For the study, the medical resources actually required to deal with the patient load for events within the control sample from the two stadia were compared with the number of needed resources predicted by the Medical Resource Model when that tool was applied retrospectively to the study events. The comparison was used to determine if the newly developed tool was either over- or under-predicting the resource requirements., Results: In the case of Ellis Park, the model under-predicted the basic life support (BLS) requirement for 1.5% of the events in the data set. Mean over-prediction was 209.1 minutes for BLS availability. Old Trafford displayed no events for which the Medical Resource Model would have under-predicted. The mean over-prediction of BLS availability for Old Trafford was 671.6 minutes. The intermediate life support (ILS) requirement for Ellis Park was under-predicted for seven of the total 66 events (10.6% of the events), all of which had one factor in common, that being relatively low spectator attendance numbers. Modelling for ILS at Old Trafford did not under-predict for any events. The ILS requirements showed a mean over-prediction of 161.4 minutes ILS availability for Ellis Park compared with 425.2 minutes for Old Trafford. Of the events held at Ellis Park, the Medical Resource Model under-predicted the ambulance requirement in 4.5% of the events. For Old Trafford events, the under-prediction was higher: 7.5% of cases., Conclusion: The medical resources that are deployed at a mass gathering should best match the requirement for patient care at a particular event. An important consideration for any model is that it does not continually under-predict the resources required in relation to the actual requirement. With the exception of a specific subset of events at Ellis Park, the rate of under-prediction for this model was acceptable.

- Abstract
Background: Emergency medicine (EM) training programmes are being conducted around the world but no study has assessed the procedural competence of developing nations' EM trainees., Objectives: To quantify the number of core procedures and resuscitations performed and describe the perceived procedural competency of graduates of Africa's first EM registrarship at the University of Cape Town/Stellenbosch University (UCT/SUN) in Cape Town, South Africa., Methods: All 30 graduates from the first four classes in the UCT/SUN EM programme (2007-10) were asked to complete a written, self-administered survey on the number of procedures needed for competency, the number of procedures performed during registrarship and the perceived competence in each procedure ranked on a five-point Likert scale. The procedures selected were the 10 core procedures and four types of resuscitations as defined by the US-based Residency Review Committee. Results were compiled and analysed using descriptive statistics., Results: Twenty-seven (90%) completed surveys. For most core procedures and all resuscitations, the number of procedures reported by respondents far exceeded the Residency Review Committee minimum. The three procedures not meeting the minimum were internal cardiac pacing, cricothyrotomy and periocardiocentesis. Respondents reported perceived competence in most procedures and all resuscitations., Conclusions: EM trainees in a South Africa registrarship report a high number of procedures performed for most procedures and all resuscitations. As medical education moves to the era of direct observation and other methods of assessment, more studies are needed to define and ensure procedural competence in trainees of nascent EM programmes.

- Abstract
Background: As many as 90% of all trauma-related deaths occur in developing nations, and this is expected to get worse with modernisation. The current method of creating an emergency care system by modelling after that of a Western nation is too resource-heavy for most developing countries to handle. A cheaper, more community-based model is needed to establish new emergency care systems and to support them to full maturity., Methods: A needs assessment was undertaken in Manenberg, a township in Cape Town with high violence and injury rates. Community leaders and successfully established local services were consulted for the design of a first responder care delivery model. The resultant community-based emergency first aid responder (EFAR) system was implemented, and EFARs were tracked over time to determine skill retention and usage., Results: The EFAR system model and training curriculum. Basic EFARs are spread throughout the community with the option of becoming stationed advanced EFARs. All EFARs are overseen by a local organisation and a professional body, and are integrated with the local ambulance response if one exists. On competency examinations, all EFARs tested averaged 28.2% before training, 77.8% after training, 71.3% 4 months after training and 71.0% 6 months after training. EFARs reported using virtually every skill taught them, and further review showed that they had done so adequately., Conclusion: The EFAR system is a low-cost, versatile model that can be used in a developing region both to lay the foundation for an emergency care system or support a new one to maturity.

- Abstract
Objectives: To determine the current door-to-needle time for the administration of fibrinolytics for acute myocardial infarction (AMI) in emergency centres (ECs) at three hospitals in Cape Town, and to compare it with the American Heart Association/American College of Cardiology (AHA/ACC) recommendation of 30 minutes as a marker of quality of care., Methods: A retrospective review of case notes from January 2008 to July 2010 of all patients receiving thrombolytics for AMI in the ECs of three Cape Town hospitals. The total door-to-needle time was calculated and patient demographics and presentation, physician qualification, clinical symptomology and reasons for delays in thromobolytic administration were analysed., Results: A total of 372 patients with acute ST elevation myocardial infarction (STEMI) were identified; 161 patients were eligible for the study. The median door-to-needle time achieved was 54 minutes (range 13 - 553 mins). A door-to-needle time of 30 minutes or less was achieved in 33 (20.5%) patients; 51.3% of the patients arrived by ambulance; 34% of patients had a pre-hospital 12-lead ECG; and 88.8% had typical symptoms of myocardial infarction. Medical officers administered thrombolytics to 44.7% of the patients. The predominant infarct location on ECG was inferior (55.9%)., Conclusion: A significant number of patients were not thrombolysed within 30 minutes of presentation. The lack of senior doctors, difficulty interpreting ECGs, atypical presentations and EC system delays prolonged the door-to-needle time in this study.

- Abstract
Objective: Africa's first postgraduate training program in emergency medicine (EM) was established at the University of Cape Town/Stellenbosch University (UCT/SUN) in 2004. This study of the UCT/SUN EM program investigated the backgrounds, perceptions, and experiences of its graduates., Methods: This was a cross-sectional descriptive study. The study population was the 30 graduates from the first four classes in the UCT/SUN EM program (2007-2010). We employed a scripted interview with a combination of closed and open-ended questions. Data were analyzed using the thematic method of qualitative analysis., Results: Twenty-seven (90%) graduates were interviewed. Initial career goals were primarily (78%) to practice EM in a nonacademic clinical capacity. At the time of the interview, 52% held academic positions, 15% had nonacademic clinical positions, and 33% had temporary positions and were looking for other posts. The three most commonly cited strengths of their program were diversity of clinical rotations (85%), autonomy and procedural experience (63%), and importance of being pioneers within Africa (52%). The three most commonly cited weaknesses were lack of bedside teaching in the ED (96%), lack of career options after graduation (74%), and lack of preparation for academic careers (70%)., Conclusions: The lessons identified from structured interviews with graduates from Africa's first EM training include the importance of strong clinical training, difficulty of ensuring bedside teaching in a new program, the necessity of ensuring postgraduation positions, and the need for academic training. These findings may be useful for other developing countries looking to start EM training programs.

- Abstract
The International Society for Burns Injuries (ISBI) has published guidelines for the management of multiple or mass burns casualties, and recommends that 'each country has or should have a disaster planning system that addresses its own particular needs.' The need for a national burns disaster plan integrated with national and provincial disaster planning was discussed at the South African Burns Society Congress in 2009, but there was no real involvement in the disaster planning prior to the 2010 World Cup; the country would have been poorly prepared had there been a burns disaster during the event. This article identifies some of the lessons learnt and strategies derived from major burns disasters and burns disaster planning from other regions. Members of the South African Burns Society are undertaking an audit of burns care in South Africa to investigate the feasibility of a national burns disaster plan. This audit (which is still under way) also aims to identify weaknesses of burns care in South Africa and implement improvements where necessary.

- Abstract
Background: The aim of this study was to determine whether the current South African Emergency Medicine Curriculum is appropriate for the burden of disease seen by registrars in Cape Town Emergency Centres., Method: This is a cross-sectional retrospective audit of patients presenting to a range of secondary level emergency centres (ECs) in Cape Town. The type of clinical presentations, investigations done and procedures performed were analysed. Basic descriptive statistics are presented., Results: A total of 1283 clinical presentations from three secondary level ECs in Cape Town were collated. Of these clinical presentations, 47 were not included in the South African Emergency Medicine curriculum; in addition, two were only included in the paediatrics section. 115 procedures were tabled, of these, 11 were not included in the curriculum. 730 investigations were tabled; 527 were not included in the curriculum., Conclusions: The curriculum did not cover all the clinical conditions, procedures and investigations encountered by emergency medicine (EM) registrars in Cape Town. In addition, there were multiple categories in the curriculum that were not encountered in EM practice at all. The investigations section of the curriculum correlated particularly poorly with the skills needed for the burden of disease seen in ECs in Cape Town. The curriculum should be redrafted guided by a practice analysis of EM.

- Abstract
Objective: To evaluate four paediatric weight estimation methods (APLS, Luscombe and Owens, Best Guess and Broselow tape) in order to determine which are accurate for weight estimation in South African children., Method: From a database of 2832 children aged 1-10 years seen at Red Cross Hospital in Cape Town, measured weight was compared to estimated weights from all four methods., Results: APLS formula and the Broselow Tape showed the best correlation with measured weight. Mean error was 3.3% for APLS (for 1-10-year olds) and 0.9% for Broselow tape (children <145 cm length and <35 kg). Both the Best Guess and Luscombe and Owens formulae tended to overestimate weight (15.4% and 12.4%, respectively)., Conclusion: The Broselow tape and APLS estimation methods are most accurate in estimating weight in the Western Cape paediatric population, even though they have a small tendency to underestimate weight. Clinicians need to bear in mind that none of the formulae are infallible and constant reassessment and clinical judgement should be used, as well as a measured weight as soon as possible in an emergency situation.

- Abstract
Introduction: The State University of New York at Downstate (SUNY) conducted a web-based long-distance tabletop drill (LDTT) designed to identify vulnerabilities in safety, security, communications, supplies, incident management, and surge capacity for a number of hospitals preceding the 2010 FIFA World Cup. The tabletop drill simulated a stampede and crush-type disaster at the Green Point Stadium in Cape Town, South Africa in anticipation of 2010 FIFA World Cup. The LDTT, entitled "Western Cape-Abilities", was conducted between May and September 2009, and encompassed nine hospitals in the Western Cape of South Africa. The main purpose of this drill was to identify strengths and weaknesses in disaster preparedness among nine state and private hospitals in Cape Town, South Africa. These hospitals were tasked to respond to the ill and injured during the 2010 World Cup., Methods: This LDTT utilized e-mail to conduct a 10-week, scenario-based drill. Questions focused on areas of disaster preparedness previously identified as standards from the literature. After each scenario stimulus was sent, each hospital had three days to collect answers and submit responses to drill controllers via e-mail., Results: Data collected from the nine participating hospitals met 72% (95%CI = 69%-75%) of the overall criteria examined. The highest scores were attained in areas such as equipment, with 78% (95%CI = 66%-86%) positive responses, and development of a major incident plan with 85% (95% CI = 77%-91%) of criteria met. The lowest scores appeared in the areas of public relations/risk communications; 64% positive responses (95% CI = 56%-72%), and safety, supplies, fire and security meeting also meeting 64% of the assessed criteria (95% CI = 57%-70%). Surge capacity and surge capacity revisited both met 76% (95% CI = 68%-83% and 68%-82%, respectively)., Conclusions: This assessment of disaster preparedness indicated an overall good performance in categories such as hospital equipment and development of major incident plans, but improvement is needed in hospital security, public relations, and communications ahead of the 2010 FIFA World Cup.

- Abstract
BACKGROUND AND PROBLEM STATEMENT: The South African response to the Haitian earthquake consisted of two independent non-government organisations (NGOs) working separately with minimal contact. Both teams experienced problems during the deployment, mainly owing to not following the International Search and Rescue Advisory Group (INSARAG) guidelines., Critical Areas Identified: To improve future South African disaster responses, three functional deployment categories were identified: urban search and rescue, triage and initial stabilisation, and definitive care. To best achieve this, four critical components need to be taken into account: rapid deployment, intelligence from the site, government facilitation, and working under the auspices of recognised organisations such as the United Nations and the World Health Organization., Conclusion: The proposed way forward for South African medical teams responding to disasters is to be unified under a leading academic body, to have an up-to-date volunteer database, and for volunteers to be current with the international search and rescue course currently being developed by the Medical Working Group of INSARAG. An additional consideration is that South African rescue and relief personnel have a primary responsibility to the citizens of South Africa, then the Southern African Development Community region, then the rest of the African continent and finally further afield. The commitment of government, private and military health services as well as NGOs is paramount for a unified response.

- Abstract
Background: In a resource poor setting with poverty, a high burden of disease and critically low medical staff numbers, triage could potentially improve the long waiting times experienced at South African public hospital emergency departments (ED) and render timely emergency care to those in most need., Aim: To evaluate the impact of introducing nurse triage (using the Cape Triage Score (CTS)) on waiting times for patients presenting to a South African public hospital ED., Methods: Pre-triage waiting times were collected retrospectively through accessing hospital records of four randomly chosen months of the preceding year. This was compared with data collected prospectively over a 3 month period using nurse triage and the CTS triage tool. Captured data included CTS priority category, time of nurse triage and time of attendance by ED doctor., Results: Waiting times were significantly reduced in all but the lowest priority category. The introduction of nurse triage, using the CTS, resulted in an overall reduction in waiting time from 237 min to 146 min (p<0.001). Patients triaged "red" (highest priority) demonstrated a mean reduction in waiting time from 216 min to 38 min (p<0.001)., Conclusions: The results demonstrate that use of the CTS, as implemented by trained nurses, dramatically reduced the waiting time of patients attending a busy public hospital ED in South Africa.

- Abstract
Background: Until recently South Africa had no triage system for emergency department (ED) use. The Cape triage group developed a triage scale called the Cape triage score (CTS). This system consists of a basic physiology score, mobility score and a short list of important discriminators that cannot be accurately triaged on a physiological score alone. Highest priority is given to a red colour code, followed by orange, yellow and green., Aim: The purpose was to evaluate the components of the CTS and identify amendments that would improve the quality of the scale in terms of its accuracy to identify patients more likely to require admission or at high risk of death in the ED., Methods: Data were prospectively collected over a 4-month period. Data captured included the parameters of a basic physiological score (respiratory rate, pulse rate, systolic blood pressure, temperature and a simplified score measuring level of consciousness), mobility, a list of selected clinical conditions (discriminator list), final clinical diagnosis and final outcome in the ED (admission to hospital or death)., Results: 798 patients were triaged and analyzed. The CTS undertriaged 24% (overtriage 25%) of cases who required admission. By altering the colour code parameters, amending the discriminator list as well as the addition of a trauma factor, undertriage was reduced to 12% (with an overtriage of 45%)., Conclusions: The amended CTS has an acceptably low undertriage rate and is capable of predicting patient disposal over a wide spectrum of ED presentations.

- Abstract
Background: The South African setting lends itself to the extensive use of air transport. There is a perception with healthcare providers that flight crews spend too much time with a patient before departure. The main advantage of aero medical transport is to minimise the delay to definitive care and prolonged on-scene time defies this objective. A study was carried out to examine the mean on-scene times of aero medical and road transport of critically ill patients in the Western Cape of South Africa., Methods: In this retrospective observational study, all critically ill patients transported in the Western Cape between September 2005 and May 2006 were evaluated. The mean on-scene time for each transport mode was calculated. Road transport was compared with air transport (rotor and fixed wing). Every transport mode was further divided into mission types: "scene" missions (scene to a healthcare facility) or "inter-facility" missions (from one healthcare facility to another)., Results: A total of 7924 transports were included in the study, 7580 of which (95.7%) were road transports. The air transport group spent 53.2 min (95% CI 51.1 to 55.4) at the scene compared with 27.9 min (95% CI 27.5 to 28.4) for the road transport group. There was a significant difference between scene and inter-facility missions in the air transport group (mean 31.7 min for scene missions vs 58.7 min for inter-facility missions; p<0.001). A significant difference was also found in the road transport (mean 24.6 min for scene missions vs 31.9 min for inter-facility missions; p<0.001)., Conclusion: The on-scene time for transport missions by road is significantly less than for those done by air. There are significant differences between scene and inter-facility missions in both transport modes. Capacity building programmes with ongoing education and training of staff at referring facilities should be implemented.

Introduction: Little is known about the nature of patients presenting to emergency departments (EDs) in South Africa. This study aimed to provide evidence on ED usage in Cape Town by studying patients at four community health centre (CHC) EDs, with details of the severity of their presentation and their disposal., Methods: A total of 16,392 patients presented in this 8-week prospective observational study, and 15,681 were included in the descriptive data analysis. One-quarter were children., Results: There were clear and predictable peaks in attendance after 1600 hr and at weekends, with a steady stream of patients presenting overnight. Case severity was evenly distributed between emergency, urgent and routine care. Nearly 10% of patients were referred on to a higher level of care., Conclusion: The data from this study present a model for staffing and resource allocation. It has implications for the provision of emergency care in CHC EDs.

Background: The authors have recently presented reference ranges for heart rate and respiratory rate in healthy resting schoolchildren, aged 4-16 years, in the United Kingdom. There are no similar ranges for children in the developing world., Aims: To undertake a study in Cape Town, South Africa, to establish whether the UK ranges may be applied to socioeconomically disadvantaged groups., Methods: Data on 346 children in a township school were recorded; their height, weight, heart rate, and respiratory rate were compared to the UK ranges., Results: The two groups plotted closely together by height and weight on the UK 90 growth reference charts. There was no difference in heart rate between the two groups, and a difference of 0.46 breathes per minutes in respiratory rate, which is not felt to be of clinical significance., Conclusion: The reference rages of heart and respiratory rate derived in the UK may be applied to children in developing world situations.

The Cape Triage Group (CTG) convened with the intention of producing a triage system for the Western Cape, and eventually South Africa. The group includes in-hospital and prehospital staff from varied backgrounds. The CTG triage protocol is termed the Cape Triage Score (CTG), and has been developed by a multi-disciplinary panel, through best available evidence and expert opinion. The CTS has been validated in several studies, and was launched across the Western Cape on 1 January 2006. The CTG would value feedback from readers of this journal, as part of the ongoing monitoring and evaluation process.
