RESUMEN
OBJECTIVES: Despite better access to antiretroviral therapy (ART) over recent years, HIV remains a major global cause of mortality. The present study aimed to identify predictors of in-hospital mortality among HIV-positive patients presenting to an emergency department (ED). METHODS: In this cross-sectional study, HIV-positive patients presenting to the Charlotte Maxeke Johannesburg Academic Hospital adult ED between 07 July 2017 and 18 October 2018 were prospectively enrolled. Data were compared between participants who survived to hospital discharge and those who died. The data were further subjected to univariate and multivariate logistic regression analyses to determine variables that were associated with in-hospital mortality. RESULTS: Of a total of 1224 participants, the in-hospital mortality was 13.6% (n = 166). On multivariate analysis, respiratory rate > 20 breaths/min [odds ratio (OR) = 1.90, P = 0.012], creatinine > 120 µmol/L (OR = 1.97, P = 0.006), oxygen saturation < 90% (OR = 2.09, P = 0.011), white cell count < 4.0 × 109 /L (OR = 2.09, P = 0.008), ART non-adherence or not yet on ART (OR = 2.39, P = 0.012), Glasgow Coma Scale < 15 (OR = 2.53, P = 0.000), albumin < 35 g/L (OR = 2.61, P = 0.002), lactate > 2 mmol/L (OR = 4.83, P = 0.000) and cryptococcal meningitis (OR = 6.78, P = 0.000) were significantly associated with in-hospital mortality. CONCLUSIONS: Routine clinical and laboratory parameters are useful predictors of in-hospital mortality in HIV-positive patients presenting to the ED with an acute illness. These parameters may be of value in guiding clinical decision-making, directing the appropriate use of resources and influencing patient disposition, and may also be useful in developing an outcome prediction tool.

OBJECTIVES: Compared to other countires internationally, South Africa has the largest number of people living with HIV. There are limited data in developing countries on the outcomes of HIV-infected patients in the intensive care unit (ICU). The objectives of this study were to describe the pattern of presentation of these patients and to determine factors that may influence survival to ICU discharge. METHODS: The medical charts of 204 consecutive HIV-infected individuals who were admitted to the Charlotte Maxeke Johannesburg Academic Hospital adult general ICU during the calendar year 2017 were retrospectively reviewed. Relevant data were subjected to univariate and multivariate analysis. RESULTS: Two-hundred and four (22.6%) out of a total of 903 patients who were admitted to the ICU were HIV positive. Sepsis-related illnesses were the most common reason for ICU admission (n = 95; 46.6%), followed by post-operative care (n = 69; 33.8%) and non-sepsis-related illnesses (n = 40; 19.6%). The median length of stay in the ICU was 5 (interquartile range 2-9) days. ICU mortality was 33.3% (n = 68). On univariate analysis, age (P = 0.039), length of stay in the ICU (P = 0.040), primary diagnostic category (P < 0.05), sepsis acquired during the ICU stay (P = 0.012), inotrope/vasopressor administration (P < 0.001), mechanical ventilation (P < 0.001), haemodialysis (P = 0.001), CD4 cell count (P = 0.011), Acute Physiology and Chronic Health Assessment (APACHE) II score (P < 0.001) and Sequential Organ Failure Assessment (SOFA) score (P < 0.001) were significantly associated with mortality. CONCLUSIONS: Age, diagnostic category, sepsis acquired during the ICU stay, inotrope/vasopressor administration, mechanical ventilation, haemodialysis, CD4 cell count, APACHE II score, SOFA score and length of ICU stay were associated with ICU mortality in HIV-infected patients.

BACKGROUND: With 23.5 suicide-related deaths per 100 000 population, South Africa (SA) has the eighth-highest age-standardised suicide rate in the world. Intentional self-poisoning is associated with significant morbidity, mortality and cost. In SA, self-poisoning is the leading method of suicide in females and the second leading method in males. OBJECTIVES: To determine the profile of patients presenting with intentional self-poisoning to the Charlotte Maxeke Johannesburg Academic Hospital emergency department. METHODS: The study was a cross-sectional, retrospective audit of the medical records of patients who presented over a 12-month period with intentional self-poisoning. RESULTS: Of the 288 patients included, 62.8% were female, 62.1% were aged 18 - 30 years, 22.2% were foreign nationals, 88.9% were single, 62.8% were unemployed, 82.3% reported that the episode was precipitated by an acute stressful event, 5.6% required intensive care unit (ICU) admission, and 4.5% died prior to hospital discharge. Organophosphate/carbamate pesticide ingestion was the most common method of self-poisoning (25.3%) and was responsible for the majority of ICU admissions (81.3%), cases requiring hospitalisation for >6 days (56.5%) and deaths (69.2%). CONCLUSION: A large proportion of patients were female, 18 - 30 years of age, single, unemployed, and reported an acute stressful event as a precipitant. Organophosphate/carbamate pesticide ingestion was the most common method of self-poisoning and accounted for the majority of deaths and ICU admissions. Nationwide efforts should be aimed at enhancing awareness and implementing strategies to identify those at increased risk of suicidal behaviour.

BACKGROUND: Emergency medical service (EMS) personnel are exposed to high levels of psychological, physical and emotional stressors. There has been an increase in stimulant use among healthcare professionals worldwide. There is a paucity of data pertaining to the use of stimulant products among EMS personnel in South Africa (SA). OBJECTIVES: To determine the prevalence of and other aspects pertaining to use of stimulant products among EMS personnel in Gauteng Province, SA. METHODS: A prospective cross-sectional study using a questionnaire-based model was used to survey EMS personnel in Gauteng. RESULTS: Of the 315 respondents who completed the questionnaire, 310 (98.4%) reported use of stimulant products, 295 (93.7%) consumed tea/coffee, 187 (59.4%) consumed commercial energy drinks, 60 (19.0%) used caffeinated energy-enhancing tablets, 14 (4.4%) used non-caffeinated prescription stimulant medications, 50 (15.9%) used illicit drugs, 134 (42.5%) exceeded the recommended daily allowance (RDA) of caffeine, 201 (63.8%) exceeded the RDA of sugar, 231 (73.3%) experienced difficulty remaining awake during a shift, 148 (47.8%) used stimulants off shift, and 71 (22.5%) experienced insomnia. Common reasons for use of stimulants were enjoyment (n=218; 69.2%), to stay awake (n=125; 39.7%) and improvement of physical and mental performance (n=94; 29.8%). CONCLUSIONS: The high prevalence of stimulant use among respondents is a cause for concern. Strategies to address it should be aimed at promoting awareness and education, improving working conditions, enhancing support structures, and regulating the stimulant content of commercial products.

BACKGROUND: Suboptimal antiretroviral therapy (ART) adherence is associated with viral resistance, opportunistic infections and increased mortality. OBJECTIVES: To determine the rates of ART non-adherence and its associations, and also the reasons for ART non-adherence, among HIV-positive patients presenting to a major central hospital emergency department (ED). METHODS: Consecutive HIV-positive patients presenting to the Charlotte Maxeke Johannesburg Academic Hospital adult ED between 7 July 2017 and 18 October 2018 were prospectively enrolled. Self-reported adherence was assessed using the AIDS Clinical Trials Group Adherence Questionnaire (ACTG-AQ). RESULTS: Of the 1 224 consecutive HIV-positive participants enrolled, 761 (75.2%) were on ART at the time of ED presentation. Of these, 245 (32.2%) were non-adherent as per the ACTG-AQ. Participants not yet on ART prior to ED presentation had significantly higher in-hospital mortality than participants on ART (odds ratio 1.69; 95% confidence interval 1.21 - 2.34; p=0.002). Younger age, male sex, CD4 count <100 cells/µL, lack of viral suppression, a high National Early Warning Score 2 (≥7 points) and length of hospital stay ≥7 days were significantly associated with ART non-adherence (p<0.05). Forgetfulness (13.9%) and lack of social support, depression/stress/mental illness, and lack of money for transport to collect medications (9.9% each) were the most common reasons given for ART non-adherence. CONCLUSIONS: Of HIV-positive patients presenting to the ED, a high proportion were either not yet initiated on ART or ART non-adherent. HIV programmes should focus on HIV-positive ED attendees with the aim of identifying high-risk patients and providing adequate ART adherence support.

SARS-CoV-2 has resulted in a global pandemic within months following its initial detection. South Africa (SA), like many other countries, was not prepared for the impact this novel infection would have on the healthcare system. In this paper, the authors discuss the challenges experienced while facing COVID-19 at a tertiary-level institution in Gauteng province, SA, and the dynamic strategies implemented to deal with the epidemic.

BACKGROUND: Intensive care unit (ICU)-related healthcare-associated infections (HCAIs) are two to three times higher in lower-income countries than in higher-income ones. Hand cleansing and other hygiene measures have been documented as one of the most effective measures in combating the transmission of HCAIs. There is a paucity of data pertaining to hygiene practices in the ICU in developing countries. OBJECTIVES: To determine compliance with hygiene practices among healthcare workers in a tertiary hospital ICU. METHODS: Hygiene practices of healthcare workers in a tertiary academic hospital ICU in Johannesburg, South Africa, were discreetly observed over an 8-week period. Compliance with hand cleansing and other hygiene practices was documented and analysed. Retrospective consent was obtained, and subject confidentiality was maintained. RESULTS: A total of 745 hygiene opportunities were observed. Of the 156 opportunities where handwashing with soap and water was indicated (20.9%), compliance was noted in 89 cases (57.1%), while an alcohol-based hand rub was inappropriately used in 34 cases (21.8%) and no hand hygiene was performed in the remaining 33 cases (21.1%). Of the 589 opportunities where an alcohol-based hand-rub was indicated, it was used in 312 cases (53.0%). Compliance with the donning of disposable surgical gloves, disposable plastic aprons and being 'bare below the elbows' was noted in 114 (90.6%), 108 (71.1%) and 355 (47.7%) opportunities, respectively, where these were indicated. CONCLUSIONS: Overall compliance with hygiene measures among healthcare workers in the ICU was suboptimal in this study, but in keeping with general international trends. Regular retraining of staff, frequent reminders, peer oversight and regular audits may improve compliance.

Power failures and the lack of a robust contingency plan could prove catastrophic in any healthcare environment, with varied and far-reaching consequences. In 2003, a 28% rise in both accidental and non-accidental deaths was recorded in the USA as a result of mass power outages. For every day with a power outage lasting longer than 2 hours, hospital mortality has been estimated to increase by 43%.
