How much time do doctors spend providing care to each child in the ED? A time and motion study.

BACKGROUND: The total time per patient doctors spend providing care in emergency departments (EDs) has implications for the development of evidence-based ED staffing models. We sought to measure the total time taken by doctors to assess and manage individual paediatric patients presenting to two EDs in the Western Cape, South Africa and to compare these averages to the estimated benchmarks used regionally to calculate ED staffing allocations. METHODS: We conducted a cross-sectional, observational study applying time and motion methodology, using convenience sampling. Data were collected over a 5-week period from 11 December 2015 to 18 January 2016 at Khayelitsha District Hospital Emergency Centre and Tygerberg Hospital Paediatric Emergency and Ambulatory Unit. We assessed total doctor time for each patient stratified by acuity level using the South African Triage Scale. RESULTS: Care was observed for a total of 100 patients. Median age was 21 months (IQR 8-55). Median total doctor time per patient (95% CI) was 31 (22 to 38), 39 (31 to 63), 48 (32 to 63) and 96 (66 to 122) min for triage categories green, yellow, orange and red, respectively. Median timing was significantly higher than the estimated local benchmark for the lowest acuity 'green' triage category (31 min (22 to 38) vs 15 min; p=0.001) and the highest acuity 'red' category (96 min (66 to 122) vs 50 min; p=0.002). CONCLUSION: Doctor time per patient increased with increasing acuity of triage category and exceeded estimated benchmarks for the highest and lowest acuities. The distinctive methodology can easily be extended to other settings and populations.

The value of electrocardiography in predicting inpatient mortality in patients with acute pulmonary embolism: A cross sectional analysis.

Introduction: Pulmonary embolism (PE) is a significant global cause of mortality, ranking third after myocardial infarction and stroke. ECG findings may play a valuable role in the prognostication of patients with PE, with various ECG abnormalities proving to be reasonable predictors of haemodynamic decompensation, cardiogenic shock, and even mortality. This study aims to assess the value of electrocardiography in predicting inpatient mortality in patients with acute pulmonary embolism, as diagnosed with computed tomography pulmonary angiogram. Method: This study was a cross sectional analysis based at Tygerberg Hospital, Cape Town, South Africa. Eligible patients were identified from all CT-PA performed between 1 January 2017 and 31 December 2019 (2 years). The ECGs were independently screened by two blinded emergency physicians for predetermined signs that are associated with right heart strain and higher pulmonary artery pressures, and these findings were analysed to in-hospital mortality. Results: Of the included 81 patients, 61 (75 %) were female. Of the 41 (51 %) patients with submassive PE and 8 (10 %) with massive PE, 7 (17 %) and 3 (38 %) suffered inpatient mortality (p = 0.023) respectively. Univariate ECG analysis revealed that complete right bundle branch block (OR, 8.6; 95 % CI, 1.1 to 69.9; p = 0.044) and right axis deviation (OR, 5.6; 95 % CI, 1.4 to 22.4; p = 0.015) were significant predictors of inpatient mortality. Conclusion: Early identification of patients with pulmonary embolism at higher risk of clinical deterioration and in-patient mortality remains a challenge. Even though no clinical finding or prediction tool in isolation can reliably predict outcomes in patients with pulmonary embolism, this study demonstrated two ECG findings at presentation that were associated with a higher likelihood of inpatient mortality. This single-centre observational study with a small sample precludes concrete conclusions and a large follow-up multi-centre study is advised.

Characterizing myocardial edema and fibrosis in hypertensive crisis with cardiovascular magnetic resonance imaging.

A hypertensive crisis is associated with an increased risk of cardiovascular events. Although altered cardiac structure, function, and myocardial architecture on cardiovascular magnetic resonance (CMR) have been associated with increased adverse events in hypertensive patients, the studies did not include patients with hypertensive crisis. Our study aimed to determine myocardial tissue characteristics in patients with hypertensive crisis using CMR imaging. Participants underwent comprehensive CMR imaging at 1.5T. The imaging protocol included cine-, T2-weighted-, contrasted- and multi-parametric mapping images. Blood and imaging biomarkers were compared in hypertensive emergency and hypertensive urgency. Predictors of myocardial edema was assessed using linear regression. The predictive value of T1- and T2 mapping for identifying hypertensive emergency (from urgency) was assessed with receiver operator characteristics curves. Eighty-two patients (48.5 ± 13.4 years, 57% men) were included. Hypertensive emergency constituted 78%. Native T1 was higher in patients with LVH compared to those without (1056 ± 33 vs. 1013 ± 40, P < 0.001), and tended to be higher in hypertensive emergency than urgency (1051 ± 37 vs. 1033 ± 40, P = 0.077). T2-w signal intensity (SI) ratio and T2 mapping values were higher in hypertensive emergency (1.5 ± 0.2 vs. 1.4 ± 0.1, P = 0.044 and 48 ± 2 vs. 47 ± 2, P = 0.004), and in patients with than without LVH (1.5 ± 0.2 vs. 1.4 ± 0.1, P = 0.045 and P = 0.030). A trend for higher extracellular volume was noted in hypertensive emergency compared to urgency (25 ± 4 vs. 22 ± 3, P = 0.050). Native T1 correlated with T2 mapping (rs = 0.429, P < 0.001), indexed LV mass (rs = 0.493, P < 0.001), cardiac troponin (rs = 0.316, P < 0.001) and NT-proBNP (rs = 0.537, P < 0.001), while T2 correlated with cardiac troponin (rs = 0.390, P < 0.001), and NT-proBNP (rs = 0.348, P < 0.001). Non-ischemic LGE pattern occurred in 59% and was 21% more prevalent in the hypertensive emergency group (P = 0.005). Our findings demonstrate that hypertensive crisis is associated with distinct myocardial tissue alterations, including increased myocardial edema and fibrosis, as detected on CMR. Patients with hypertensive emergency had a higher degree of myocardial oedema than hypertensive urgency. Further research is necessary to explore the prognostic value of these findings.

Deeply jaundiced: Not so surgical after all.

Leptospirosis is an under-recognised disease in sub-Saharan Africa and the diagnosis requires a high index of suspicion. This case report highlights the protean manifestations of leptospirosis. Leptospirosis should be considered in any patient presenting with fever and jaundice, especially when there has been a history of occupational or recreational exposure to water, soil or rodents. Contribution: This case report describes a typical case of leptospirosis, which often presents as a diagnostic dilemma.

Myocardial Tissue Characterization in Patients with Hypertensive Crisis, Positive Troponin, and Unobstructed Coronary Arteries: A Cardiovascular Magnetic Resonance-Based Study.

Hypertensive crisis can present with cardiac troponin elevation and unobstructed coronary arteries. We used cardiac magnetic resonance (CMR) imaging to characterize the myocardial tissue in patients with hypertensive crisis, elevated cardiac troponin, and unobstructed coronary arteries. Patients with hypertensive crisis and elevated cardiac troponin with coronary artery stenosis <50% were enrolled. Patients with troponin-negative hypertensive crisis served as controls. All participants underwent CMR imaging at 1.5 Tesla. Imaging biomarkers and tissue characteristics were compared between the groups. There were 19 patients (63% male) with elevated troponin and 24 (33% male) troponin-negative controls. The troponin-positive group was older (57 ± 11 years vs. 47 ± 14 years, p = 0.015). The groups had similar T2-weighted signal intensity ratios and native T1 times. T2 relaxation times were longer in the troponin-positive group, and the difference remained significant after excluding infarct-pattern late gadolinium enhancement (LGE) from the analysis. Extracellular volume (ECV) was higher in the troponin-positive group (25 ± 4 ms vs. 22 ± 3 ms, p = 0.008) and correlated strongly with T2 relaxation time (rs = 0.701, p = 0.022). Late gadolinium enhancement was 32% more prevalent in the troponin-positive group (82% vs. 50%, p = 0.050), with 29% having infarct-pattern LGE. T2 relaxation time was independently associated with troponin positivity (OR 2.1, p = 0.043), and both T2 relaxation time and ECV predicted troponin positivity (C-statistics: 0.71, p = 0.009; and 0.77, p = 0.006). Left ventricular end-diastolic and left atrial volumes were the strongest predictors of troponin positivity (C-statistics: 0.80, p = 0.001; and 0.82, p < 0.001). The increased T2 relaxation time and ECV and their significant correlation in the troponin-positive group suggest myocardial injury with oedema, while the non-ischaemic LGE could be due to myocardial fibrosis or acute necrosis. These CMR imaging biomarkers provide important clinical indices for risk stratification and prognostication in patients with hypertensive crisis.

Cardiac Morphology, Function, and Left Ventricular Geometric Pattern in Patients with Hypertensive Crisis: A Cardiovascular Magnetic Resonance-Based Study.

(1) Background: Altered cardiac morphology and function are associated with increased risks of adverse cardiac events in hypertension. Our study aimed to assess left ventricular (LV) morphology, geometry, and function using cardiovascular magnetic resonance (CMR) imaging in patients with hypertensive crisis. (2) Methods: Patients with hypertensive crisis underwent CMR imaging at 1.5 Tesla to assess cardiac volume, mass, function, and contrasted study. Left ventricular (LV) function and geometry were defined according to the guideline recommendations. Late gadolinium enhancement (LGE) was qualitatively assessed and classified into ischemic and nonischemic patterns. Predictors of LGE was determined using regression analysis. (3) Results: Eighty-two patients with hypertensive crisis (aged 48.5 ± 13.4 years, and 57% males) underwent CMR imaging. Of these patients, seventy-eight percent were hypertensive emergency and twenty-two percent were urgency. Diastolic blood pressure was higher under hypertensive emergency (p = 0.032). Seventy-nine percent (92% of emergency vs. 59% of urgency, respectively; p = 0.003) had left ventricular hypertrophy (LVH). The most prevalent LV geometry was concentric hypertrophy (52%). Asymmetric LVH occurred in 13 (22%) of the participants after excluding ischemic LGE. Impaired systolic function occurred in 46% of patients, and predominantly involved hypertensive emergency. Nonischemic LGE occurred in 75% of contrasted studies (67.2% in emergency versus 44.4% in urgency, respectively; p < 0.001). Creatinine and LV mass were independently associated with nonischemic LGE. (5) Conclusion: LVH, altered geometry, asymmetric LVH, impaired LV systolic function, and LGE are common under hypertensive crisis. LVH and LGE more commonly occurred under hypertensive emergency. Longitudinal studies are required to determine the prognostic implications of asymmetric LVH and LGE in hypertensive crisis.

Clinical Profile of Patients with Hypertensive Emergency Referred to a Tertiary Hospital in the Western Cape Province of South Africa.

BACKGROUND: Despite advances in managing hypertension, hypertensive emergencies remain a common indication for emergency room visits. Our study aimed to determine the clinical profile of patients referred with hypertensive emergencies. METHODS: We conducted an observational study involving patients aged ≥18 years referred with hypertensive crisis. A diagnosis of hypertensive emergencies was based on a systolic blood pressure (BP) ≥180 mmHg and/or a diastolic BP ≥110 mmHg, with acute hypertension-mediated organ damage (aHMOD). Patients without evidence of aHMOD were considered hypertensive urgencies. Hypertensive disorders of pregnancy and unconscious patients were excluded from the study. RESULTS: Eighty-two patients were included, comprising 66 (80.5%) with hypertensive emergencies and 16 (19.5%) with hypertensive urgencies. The mean age of patients with hypertensive emergencies was 47.9 (13.2) years, and 66.7% were males. Age, systolic BP, and duration of hypertension were similar in the hypertensive crisis cohort. Most patients with hypertensive emergencies reported nonadherence to medication (78%) or presented de novo without a prior diagnosis of hypertension (36%). Cardiac aHMOD (acute pulmonary edema and myocardial infarction) occurred in 66%, while neurological emergencies (intracranial hemorrhage, ischemic stroke, and hypertensive encephalopathy) occurred in 33.3%. Lactate dehydrogenase (LDH) (P < 0.001), NT-proBNP (P=0.024), and cardiac troponin (P<0.001) were higher in hypertensive emergencies compared to urgencies. LDH did not differ in the subtypes of hypertensive emergencies. CONCLUSION: Cardiovascular and neurological emergencies are the most common hypertensive emergencies. Most patients reported nonadherence to medication or presented de novo without a prior diagnosis of hypertension.

The Role of Cardiac Biomarkers in the Diagnosis of Hypertensive Emergency.

There is a growing interest in the role of biomarkers in differentiating hypertensive emergency from hypertensive urgency. This study aimed to determine the diagnostic utility of lactate dehydrogenase (LDH), high-sensitivity cardiac troponin T (hscTnT), and N-terminal prohormone of brain-type natriuretic peptide (NT-proBNP) for identifying hypertensive emergency. A diagnosis of hypertensive emergency was made based on a systolic blood pressure of ≥180 mmHg and/or a diastolic blood pressure of ≥110 mmHg with acute hypertension-mediated organ damage. The predictive value of LDH, hscTnT, NT-proBNP, and models of these biomarkers for hypertensive emergency was determined using the area under the receiver operator characteristic curve (AUC). There were 66 patients (66.7% male) with a hypertensive emergency and 16 (31.3% male) with hypertensive urgency. LDH, NT-proBNP, and hscTnT were significantly higher in hypertensive emergency. Serum LDH > 190 U/L and high creatinine were associated with hypertensive emergency. LDH had an AUC ranging from 0.87 to 0.92 for the spectrum of hypertensive emergencies, while hscTnT had an AUC of 0.82 to 0.92, except for neurological emergencies, in which the AUC was 0.72. NT-proBNP was only useful in predicting acute pulmonary edema (AUC of 0.89). A model incorporating LDH with hscTnT had an AUC of 0.92 to 0.97 for the spectrum of hypertensive emergencies. LDH in isolation or combined with hscTnT correctly identified hypertensive emergency in patients presenting with hypertensive crisis. The routine assessment of these biomarkers has the potential to facilitate the timely identification of hypertensive emergencies, especially in patients with subtle and subclinical target organ injury.

Cardiopulmonary resuscitation in low-resource settings: a statement by the International Liaison Committee on Resuscitation, supported by the AFEM, EUSEM, IFEM, and IFRC.

Most recommendations on cardiopulmonary resuscitation were developed from the perspective of high-resource settings with the aim of applying them in these settings. These so-called international guidelines are often not applicable in low-resource settings. Organisations including the International Liaison Committee on Resuscitation (ILCOR) have not sufficiently addressed this problem. We formed a collaborative group of experts from various settings including low-income, middle-income, and high-income countries, and conducted a prospective, multiphase consensus process to formulate this ILCOR Task Force statement. We highlight the discrepancy between current cardiopulmonary resuscitation guidelines and their applicability in low-resource settings. Successful existing initiatives such as the Helping Babies Breathe programme and the WHO Emergency Care Systems Framework are acknowledged. The concept of the chainmail of survival as an adaptive approach towards a framework of resuscitation, the potential enablers of and barriers to this framework, and gaps in the knowledge are discussed, focusing on low-resource settings. Action points are proposed, which might be expanded into future recommendations and suggestions, addressing a large diversity of addressees from caregivers to stakeholders. This statement serves as a stepping-stone to developing a truly global approach to guide resuscitation care and science, including in health-care systems worldwide.

After-hour trauma-radiograph interpretation in the emergency centre of a District Hospital.

Introduction: Plain radiographs remain a first-line trauma investigation. Most trauma radiographs worldwide are reported by junior doctors. This study assesses the accuracy of after-hour acute trauma radiograph reporting by emergency centre (EC) doctors in an African district hospital. Methods: An institutional review board approved retrospective descriptive study over two consecutive weekends in February 2020. The radiologist report on the admission radiographs of adult trauma patients was compared with the initial EC interpretation. The accuracy, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for EC interpretation were calculated with 95% confidence intervals (95%CI). The association between reporting accuracy and anatomical region, mechanism of injury, time of investigation, and the number of abnormalities per radiograph was assessed. Results: 140 radiographs were included, of which 49 (35%) were abnormal. EC doctors recorded (95%CI) 77% (69-84%) accuracy, 38% (25-54%) sensitivity, 97% (91-99%) specificity, 86% (65-95%) PPV and 76% (71-80%) NPV. Performance was associated with the anatomical region (p=0.02), mechanism of injury (p=<0.01) time of day (p=0.04) and the number of abnormalities on the film (p=<0.01). The highest sensitivity was achieved in reports of the appendicular skeleton (42%) and in the setting of simple blunt trauma (62%). Overall accuracy was in line with the range (44%-99%) reported in the international literature. Discussion: Accurate reporting of acute trauma radiographs is challenging. Key factors impact performance. Further training of junior doctors in this area of clinical practice is recommended. Future work should focus on assessing the impact of such training on reporting performance.

Clinical characteristics associated with mortality of COVID-19 patients admitted to an intensive care unit of a tertiary hospital in South Africa.

BACKGROUND: Over 130 million people have been diagnosed with Coronavirus disease 2019 (COVID-19), and more than one million fatalities have been reported worldwide. South Africa is unique in having a quadruple disease burden of type 2 diabetes, hypertension, human immunodeficiency virus (HIV) and tuberculosis, making COVID-19-related mortality of particular interest in the country. The aim of this study was to investigate the clinical characteristics and associated mortality of COVID-19 patients admitted to an intensive care unit (ICU) in a South African setting. METHODS AND FINDINGS: We performed a prospective observational study of patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection admitted to the ICU of a South African tertiary hospital in Cape Town. The mortality and discharge rates were the primary outcomes. Demographic, clinical and laboratory data were analysed, and multivariable robust Poisson regression model was used to identify risk factors for mortality. Furthermore, Cox proportional hazards regression model was performed to assess the association between time to death and the predictor variables. Factors associated with death (time to death) at p-value < 0.05 were considered statistically significant. Of the 402 patients admitted to the ICU, 250 (62%) died, and another 12 (3%) died in the hospital after being discharged from the ICU. The median age of the study population was 54.1 years (IQR: 46.0-61.6). The mortality rate among those who were intubated was significantly higher at 201/221 (91%). After adjusting for confounding, multivariable robust Poisson regression analysis revealed that age more than 48 years, requiring invasive mechanical ventilation, HIV status, procalcitonin (PCT), Troponin T, Aspartate Aminotransferase (AST), and a low pH on admission all significantly predicted mortality. Three main risk factors predictive of mortality were identified in the analysis using Cox regression Cox proportional hazards regression model. HIV positive status, myalgia, and intubated in the ICU were identified as independent prognostic factors. CONCLUSIONS: In this study, the mortality rate in COVID-19 patients admitted to the ICU was high. Older age, the need for invasive mechanical ventilation, HIV status, and metabolic acidosis were found to be significant predictors of mortality in patients admitted to the ICU.

The burden of HIV and tuberculosis on the resuscitation area of an urban district-level hospital in Cape Town.

INTRODUCTION: Many patients present to emergency centres with HIV and tuberculosis related emergencies. Little is known about the influence of HIV and tuberculosis on the resuscitation areas of district-level hospitals. The primary objective was to determine the burden of non-trauma patients with HIV and/or tuberculosis presenting to the resuscitation area of Khayelitsha Hospital, Cape Town. METHODS: A retrospective analysis was performed on a prospectively collected observational database. A randomly selected 12-week sample of data from the resuscitation area was used. Trauma and paediatric (<13 years) cases were excluded. Patient demographics, HIV and tuberculosis status, disease category, investigations and procedures undertaken, disposition and in-hospital mortality were assessed. HIV and tuberculosis status were determined by laboratory confirmation or from clinical records. Descriptive statistics are presented and comparisons were done using the χ2-test or independent t-test. RESULTS: A total of 370 patients were included. HIV prevalence was 38.4% (n = 142; unknown n = 78, 21.1%), tuberculosis prevalence 13.5% (n = 50; unknown n = 233, 63%), and HIV/tuberculosis co-infection 10.8% (n = 40). HIV and tuberculosis were more likely in younger patients (both p < 0.01) and more females were HIV-positive (p < 0.01). Patients with tuberculosis spend 93 min longer in the resuscitation area than those without (p = 0.02). The acuity of patients did not differ by HIV or tuberculosis status.Infectious-related diseases and diseases of the digestive system occurred significantly more in the HIV-positive group, and endocrine-related diseases and diseases of the nervous system in HIV-negative patients.HIV-positive patients received more abdominal ultrasound examinations (p < 0.01), blood cultures (p < 0.01) and intravenous antibiotics (p < 0.01). In-hospital mortality was 17% and was not influenced by HIV status (p = 0.36) or tuberculosis status (p = 0.29). CONCLUSION: This study highlights the burden of HIV and tuberculosis on the resuscitation area of a district level hospital. Neither HIV nor tuberculosis status were associated with in-hospital mortality.

Assessment of documented adherence to critical actions in paediatric emergency care at a district-level public hospital in South Africa.

INTRODUCTION: The provision of high-quality care is vital to improve child health and survival rates. A simple, practice-based tool was recently developed to evaluate the quality of paediatric emergency care in resource-limited settings in Africa. This study used the practice-based tool to describe the documented adherence to critical actions in paediatric emergency care at an urban district-level hospital in South Africa and assess its relation to clinical outcomes. METHODS: This study is a retrospective observational study covering a 19-month period (September 2017 to March 2019). Patients <13 years old, presenting to the emergency centre with one of six sentinel presentations (seizure, altered mental status, diarrhoea, fever, respiratory distress and polytrauma) were eligible for inclusion. In the patients' files, critical actions specific for each presentation were checked for completion. Post-hoc, a seventh group 'multiple diagnoses' was created for patients with more than one sentinel disease. The action completion rate was tested for association with clinical outcomes. RESULTS: In total, 388 patients were included (median age 1.1 years, IQR 0.3-3.6). The action completion rate varied from 63% (polytrauma) to 90% (respiratory distress). Participants with ≥75% action completion rate were younger (p < 0.001), presented with high acuity (p < 0.001), were more likely to be admitted (adjusted OR 2.2, 95%CI: 1.2-4.1), and had a hospital stay ≥4 days (adjusted OR 3.4, 95%CI: 1.5-7.9). CONCLUSION: A high completion rate was associated with young age, a high patient acuity, hospital admission, length of hospital stay ≥4 days, and the specific sentinel presentation. Future research should determine whether or not documented care corresponds with the quality of delivered care and the predictive value regarding clinical outcome.

Patient outcomes and experience of a task-shared screening and brief intervention service for problem substance use in South African emergency centres: a mixed methods study.

BACKGROUND: Screening, brief intervention and referral to treatment (SBIRT) programmes have resulted in generally positive outcomes in healthcare settings, particularly for problem alcohol use, yet implementation is hampered by barriers such as concerns regarding the burden on healthcare professionals. In low-resourced settings, task-sharing approaches can reduce this burden by using non-professional healthcare workers, yet data are scarce regarding the outcomes and acceptability to patients within a SBIRT service. This study aims to evaluate patient-reported outcomes, patient acceptability, perceived benefits and recommendations for improving a task-shared SBIRT service in South African emergency centres (ECs). METHODS: This mixed methods study incorporates quantitative substance use screening and patient satisfaction data collected routinely within the service at three hospitals, and qualitative semi-structured interviews with 18 EC patient beneficiaries of the programme exploring acceptability and perceived benefits of the programme, as well as recommendations to improve the service. Approximately three months after the acute EC visit, a sub-sample of patients were followed up telephonically to assess patient-reported satisfaction and substance use outcomes. RESULTS: Of the 4847 patients eligible for the brief intervention, 3707 patients (76%) used alcohol as their primary substance and 794 (16%) used cannabis. At follow-up (n = 273), significant reductions in substance use frequency and severity were noted and over 95% of patients were satisfied with the service. In the semi-structured interviews, participants identified the non-judgemental caring approach of the counsellors, and the screening and psychoeducation components of the intervention as being the most valuable, motivating them to decrease substance use and make other positive lifestyle changes. Study participants made recommendations to include group sessions, market the programme in communities and extend the programme's reach to include a broader age group and a variety of settings. CONCLUSIONS: This task-shared SBIRT service was found to be acceptable to patients, who reported several benefits of a single SBIRT contact session delivered during an acute EC visit. These findings add to the SBIRT literature by highlighting the role of non-professional healthcare workers in delivering a low-intensity SBIRT service feasible to implement in low-resourced settings.

Adult medical emergency unit presentations due to adverse drug reactions in a setting of high HIV prevalence.

INTRODUCTION: South Africa has the world's largest antiretroviral treatment programme, which may contribute to the adverse drug reaction (ADR) burden. We aimed to determine the proportion of adult non-trauma emergency unit (EU) presentations attributable to ADRs and to characterise ADR-related EU presentations, stratified according to HIV status, to determine the contribution of drugs used in management of HIV and its complications to ADR-related EU presentations, and identify factors associated with ADR-related EU presentation. METHODS: We conducted a retrospective folder review on a random 1.7% sample of presentations over a 12-month period in 2014/2015 to the EUs of two hospitals in Cape Town, South Africa. We identified potential ADRs with the help of a trigger tool. A multidisciplinary panel assessed potential ADRs for causality, severity, and preventability. RESULTS: We included 1010 EU presentations and assessed 80/1010 (7.9%) as ADR-related, including 20/239 (8.4%) presentations among HIV-positive attendees. Among HIV-positive EU attendees with ADRs 17/20 (85%) were admitted, versus 22/60 (37%) of HIV-negative/unknown EU attendees. Only 5/21 (24%) ADRs in HIV-positive EU attendees were preventable, versus 24/63 (38%) in HIV-negative/unknown EU attendees. On multivariate analysis, only increasing drug count was associated with ADR-related EU presentation (adjusted odds ratio 1.10 per additional drug, 95% confidence interval 1.03 to 1.18), adjusted for age, sex, HIV status, comorbidity, and hospital. CONCLUSIONS: ADRs caused a significant proportion of EU presentations, similar to findings from other resource-limited settings. The spectrum of ADR manifestations in our EUs reflects South Africa's colliding epidemics of infectious and non-communicable diseases. ADRs among HIV-positive EU attendees were more severe and less likely to be preventable.

Multisystem inflammatory syndrome (MIS): a multicentre retrospective review of adults and adolescents in South Africa.

OBJECTIVES: The aim of this study was to add to the descriptive data pertaining to the epidemiology, presentation, and clinical course of multisystem inflammatory syndrome (MIS) temporally associated with coronavirus disease 2019 in adults and adolescents from low- and middle-income countries. METHODS: Patients presenting to the adult wards (14 years and older) of three academic hospitals in South Africa, who were diagnosed with MIS between August 1, 2020 and May 31, 2021, were reviewed retrospectively. The presentation, laboratory and radiographic findings, and clinical course are described. RESULTS: Eleven cases of MIS were reported, four in adolescents (14-19 years) and seven in adults (≥19 years). Fever was universal. Gastrointestinal symptoms (90.9%), cardiorespiratory abnormalities (90.9%), and mucocutaneous findings (72.7%) were prominent. Echocardiography in 10/11 patients (90.9%) showed a median left ventricular ejection fraction of 26.3% (interquartile range 21.9-33.6%). All patients required high care admission and 72.7% required inotropic support. Glucocorticoids were initiated in all cases and 72.7% received intravenous immunoglobulin. CONCLUSIONS: This constitutes the largest multicentre review of adults and adolescents with MIS in Africa. MIS may be overlooked in resource-limited settings, and heightened suspicion is needed in patients with multi-organ dysfunction, especially where repeated investigations for other aetiologies are negative.

Assault-injured youth in the emergency centres of Khayelitsha, South Africa: A prospective study of recidivism and mortality.

INTRODUCTION: Violence is a major cause of death worldwide among youth. The highest mortality rates from youth violence occur in low and middle-income countries (LMICs). We sought to identify risk factors for violent re-injury and emergency centre (EC) recidivism among assault-injured youth in South Africa. METHODS: A prospective follow up study of assault injured youth and controls ages 14-24 presenting for emergency care was conducted in Khayelitsha, South Africa from 2016 to 2018. Sociodemographic and behavioral factors were assessed using a questionnaire administered during the index EC visit. The primary outcomes were return EC visit for violent injury or death within 15 months. We used multivariable logistic regression to compute adjusted odds ratios (OR) and 95% confidence intervals (CI) of associations between return EC visits and key demographic, social, and behavioral factors among assault-injured youth. RESULTS: Our study sample included 320 assault-injured patients and 185 non-assault-injured controls. Of the assault-injured, 80% were male, and the mean age was 20.8 years. The assault-injured youth was more likely to have a return EC visit for violent injury (14%) compared to the control group (3%). The non-assault-injured group had a higher mortality rate (7% vs 3%). All deaths in the control group were due to end-stage HIV or TB-related complications. The strongest risk factors for return EC visit were prior criminal activity (OR = 2.3, 95% CI = 1.1-5.1), and current enrollment in school (OR = 2.1, 95% CI = 1.0-4.6). Although the assault-injured group reported high rates of binge drinking (73%) at the index visit, this was not found to be a risk factor for violence-related EC recidivism. DISCUSSION: Our findings suggest that assault-injured youth in an LMIC setting are at high risk of EC recidivism and several sociodemographic and behavioral factors are associated with increased risk. These findings can inform targeted intervention programs.

Clinical teams' experiences of crowding in public emergency centres in Cape Town, South Africa.

INTRODUCTION: Crowding is a significant challenge for emergency centres (ECs) globally. While South Africa is not alone in reckoning with high patient demand and insufficient resources to treat these patients; staff-to-patient ratios are generally lower than in the Global North. The study of crowding and its consequences for patient care is a key research priority for strengthening the quality and efficacy of emergency care in South Africa. The study set out to understand frontline staff's perspectives on crowding in Cape Town public ECs to learn how they cope in such high- pressure working conditions, determine what they see as the factors contributing to crowding, and obtain their recommendations for reform. METHODS: This research is a qualitative study from interviews and observations at five ECs in Cape Town, conducted in June and July 2017. In total 43 staff were interviewed individually or in pairs. The interviews included physicians of varying levels of experience (25), and registered or enrolled nurses (18). Data were analysed with the qualitative text-analysis software NVivo. RESULTS: Both doctors and nurses saw crowding as a consequence of three factors: 1) limited bed space in the EC, 2) insufficient health professionals to care for admitted patients, and 3) the presence of boarders. Systemic or organizational factors as well as human resource scarcity were determined to be the key reasons for crowding. DISCUSSION: With its high patient acuity and volume and its limited human and material resources, South Africa is an important case study for understanding how emergency care providers manage working in crowded conditions. The solutions to crowding recommended by interviewees were to expand the EC workforce and to add discharge lounges and examination tables.

Emergency centre reorganization in preparation to the COVID-19 pandemic: A district hospital's dynamic adaptation response.

The COVID-19 global pandemic forced healthcare facilities to put special isolation measures in place to limit nosocomial transmission. Cohorting is such a measure and refers to placing infected patients (or under investigation) together in a designated area. This report describes the physical reorganisation of the emergency centre at Khayelitsha Hospital, a district level hospital in Cape Town, South Africa in preparation to the COVID-19 pandemic. The preparation included the identification of a person under investigation (PUI) room, converting short stay wards into COVID-19 isolation areas, and relocating the paediatric section to an area outside the emergency centre. Finally, we had to divide the emergency centre into a respiratory and non-respiratory side by utilising part of the hospital's main reception. We are positive that the preparation and reorganization of the emergency centre will limit nosocomial transmission during the expected COVID-19 surge. Our experience in adapting to COVID-19 may have useful implications for ECs throughout South Africa and in low-and-middle income countries that are preparing for this pandemic.
