TL;DR: The proposal for national health insurance (NHI) is part of a welcome resurgence in public discourse about poverty, health and access to health services in South Africa.
Abstract: The proposal for national health insurance (NHI) is part of a welcome resurgence in public discourse about poverty, health and access to health services in South Africa. Despite certain areas of progress in the country since 1994, disparities in wealth and health are among the widest in the world. In 2008, for example, 54% of South Africans had an income below $3/day. The top 10% of South Africans account for 58% of annual national personal income, while the balance of 70% received a mere 16.9%. The Gini co-efficient, a measure of income inequality, increased from 0.6 in 1995 to 0.679 in 2009.

TL;DR: This work focuses on how the host, vector, parasite and environment and their interactions have influenced malaria incidence in South Africa between 1995 and 2012.
Abstract: Locally specific epidemiological understanding is pivotal to the success of malaria elimination in South Africa. Here, we focus on how the host, vector, parasite and environment and their interactions have influenced malaria incidence in South Africa between 1995 and 2012. Broad environmental considerations are necessary, including the physical (temperature and humidity), social (migration patterns), economic (quality of housing stock) and political (regional collaboration).

TL;DR: Female learners from 31 primary schools in Nongoma and Ceza districts (KwaZulu-Natal province, South Africa) were identified for inclusion in the vaccination programme and the overall uptake was found to be high.
Abstract: Background. Cervical cancer is linked to infection of the cervix by oncogenic human papillomavirus (HPV) subtypes. The quadrivalent Gardasil vaccine (against HPV types 6, 11, 16, 18), recommended in girls 9 - 12 years of age, has been shown to be safe, immunogenic and efficacious, with minimal or no side-effects. Aim. To demonstrate the capacity of school health teams to carry out vaccinations within a school environment. Objectives. To assess the uptake of 3 doses of the vaccine, document lessons learnt and provide recommendations for a national rollout of school-based HPV vaccination for learners. Methods. Female learners (age 9 - 12 years) from 31 primary schools in Nongoma and Ceza districts (KwaZulu-Natal province, South Africa) were identified for inclusion in the vaccination programme. The 3 doses of vaccine were administered by existing school health teams. Education and training sessions were held with all stakeholders: provincial departments of health and education; school health teams; primary healthcare nurses; hospital doctors and nurses; private practitioners; school principals, teachers and governing bodies; parents; and community and traditional leaders. Results. The overall uptake of the vaccine was found to be high: 99.7%, 97.9% and 97.8% for the first, second and third doses respectively (N=963). No adverse events were attributed to the HPV vaccine. Conclusion. This project demonstrated the successful implementation of HPV vaccination among learners (ages 9 - 12 years) using school health teams.

TL;DR: Existing frameworks that guide the regulation and distribution of alcohol frequently focus on maximising the contribution of the alcohol sector to the economy, but should also take into account the associated economic, social and health costs.
Abstract: Background. The economic, social and health costs associated with alcohol-related harms are important measures with which to inform alcohol management policies and laws. This analysis builds on previous cost estimates for South Africa. Methods. We reviewed existing international best-practice costing frameworks to provide the costing definitions and dimensions. We sourced data from South African costing literature or, if unavailable, estimated costs using socio-economic and health data from secondary sources. Care was taken to avoid possible causes of cost overestimation, in particular double counting and, as far as possible, second-round effects of alcohol abuse. Results. The combined total tangible and intangible costs of alcohol harm to the economy were estimated at 10 - 12% of the 2009 gross domestic product (GDP). The tangible financial cost of harmful alcohol use alone was estimated at R37.9 billion, or 1.6% of the 2009 GDP. Discussion. The costs of alcohol-related harms provide a substantial counterbalance to the economic benefits highlighted by the alcohol industry to counter stricter regulation. Curtailing these costs by regulatory and policy interventions contributes directly and indirectly to social well-being and the economy. Conclusions. Existing frameworks that guide the regulation and distribution of alcohol frequently focus on maximising the contribution of the alcohol sector to the economy, but should also take into account the associated economic, social and health costs. Current interventions do not systematically address the most important causes of harm from alcohol, and need to be informed by reliable evidence of the ongoing costs of alcohol-related harms.

TL;DR: The prevalences of HPV infection and abnormal cytology were much higher than previously reported in general populations in South Africa and elsewhere and have implications for planning and development of cervical screening programmes in developing countries with largely unscreened populations with a high background prevalence of HIV.
Abstract: Background. Women accessing the public health system in Gauteng province, South Africa are largely unscreened for cervical cancer andhave a high background prevalence of human immunodeficiency virus (HIV) infection.Objectives. This cross-sectional study describes the age-specific prevalence of human papillomavirus (HPV) infection and cytologicalabnormalities among this urban and peri-urban population.Method. Over the period March 2009 - September 2011, 1 524 women attending public sector primary healthcare clinics were invited toparticipate in a cervical cancer screening study. All participants were screened with conventional cytology and HPV testing undertaken using the HPV linear array genotyping kit (Roche Molecular Systems).Results. Of 1 472 women with valid cytology results, abnormalities were detected in 17.3% (n=255), of which 9.1% (n=134) were high-gradesquamous intraepithelial lesions, and 0.5% (n=8) suggestive of squamous carcinoma. Of the 1 445 women with complete data, the overall and high-risk HPV DNA prevalences were 74.6% (n=1 078) and 54.3% (n=784), respectively. HPV type 16 and/or 18 were detected in 19.5% (n=282) of women. Age-specific prevalence of HPV showed a plateau-shaped curve.Conclusions. The prevalences of HPV infection and abnormal cytology were much higher than previously reported in general populations in South Africa and elsewhere. Higher age-specific prevalence and similar plateau-like age-specific epidemiological curves have previouslyonly been described in studies among HIV-positive women. These findings have implications for planning and development of cervical screening programmes in developing countries with largely unscreened populations with a high background prevalence of HIV.

TL;DR: What South Africa has achieved in the past and where it needs to go in the future are looked at, not only to maintain the status quo, but hopefully to eliminate transmission of the disease within its borders.
Abstract: In Africa today, the drive towards controlling malaria is comparable with efforts made in the 1950s and 1960s during the World Health Organization's Global Malaria Eradication Campaign. Unlike the Eradication Campaign that 'covered' the globe but excluded Africa, the current endeavours focus on Africa, but not to the exclusion of the rest of the tropical and sub-tropical world. Major donor agencies are partnering with African governments in an attempt to curb transmission of malaria parasites, and in some countries on the edges of the distribution of malaria, there is talk of eliminating the disease. South Africa is at the very southernmost fringe of malaria distribution on the African continent and has a long history of intense malaria control activities. This article looks at what South Africa has achieved in the past and where it needs to go in the future, not only to maintain the status quo, but hopefully to eliminate transmission of the disease within its borders.

TL;DR: Cognitive outcomes in clade C-infected HIV patients in South Africa treated for 1 year with ART regimens with differing CPE scores are compared, finding that South Africa's current low CPE-scored first-line regimen performed as well as higher CPE -scored regimens.
Abstract: Background. The human immunodeficiency virus (HIV) can give rise to a spectrum of neuropsychological impairments known collectively as HIV-associated neurocognitive disorders (HAND). Although antiretroviral therapy (ART) has reduced the incidence of HIV dementia, the prevalence of milder forms of HAND has increased. It has been postulated that incomplete central nervous system (CNS) viral suppression or potential drug toxicity, both of which could be related to the CNS penetration effectiveness (CPE) of ART regimens, may contribute to this phenomenon. Objective. This study compared cognitive outcomes in clade C-infected HIV patients in South Africa treated for 1 year with ART regimens with differing CPE scores. Methods. We assessed 111 HIV-positive patients with varying levels of cognitive function at baseline (pre-ART) and then a year later. A neuropsychological battery was administered at both visits to derive global deficit scores. ART regimen data were collected at the follow-up visit. Some participants remained ART-naive during this period, thus providing a non-treatment control group. Results. Significantly more ART recipients maintained or improved cognitive function compared with patients not on ART ( p =0.017). There was no significant difference in cognitive outcomes between higher and lower CPE regimen groups ( p =0.473). Conclusions. ART preserves or improves cognition in HIV-infected patients after 1 year, irrespective of the regimen’s CPE. South Africa’s current low CPE-scored first-line regimen performed as well as higher CPE-scored regimens. These findings are reassuring for South Africa, but larger, longer-term studies would be more definitive.

TL;DR: In this article, a revised version of the paediatric South African Triage Scale (SATS) against admission as a reference standard and compared the sensitivity of triage using: (i) clinical discriminators; (ii) an age-appropriate physiological composite score; and (iii) a combination of both.
Abstract: Objective. To validate a revised version of the paediatric South African Triage Scale (SATS) against admission as a reference standard and compare the sensitivity of triage using: (i) clinical discriminators; (ii) an age-appropriate physiological composite score; and (iii) a combination of both.
Methods. A prospective cohort study was undertaken validating the revised paediatric SATS against outcome markers of children at six emergency centres during a 2-month period in 2011. The primary outcome marker was the proportion of children admitted. Validity indicators including sensitivity (Se), specificity, positive predictive value and negative predictive value (NPV) were used to estimate the validity. Associated percentages for over-/under-triage were used to further assess practical application of the paediatric SATS.
Results. A total of 2 014 children were included. The percentage of hospital admissions increased with an increase in the level of urgency from 5% in the non-urgent patients to 73% in the emergency patients. The data demonstrated that sensitivity increased substantially when using the SATS, which is a combination of clinical discriminators and the Triage Early Warning Score (TEWS) (Se 91.0%, NPV 95.3%), compared with use of clinical discriminators in isolation (Se 57.1%, NPV 86.3%) or the TEWS in isolation (Se 75.6%, NPV 89.1%).
Conclusion. The results of this study illustrate that the revised paediatric SATS is a safe and robust triage tool.

TL;DR: A concise, practical updated guideline for thromboprophylaxis and treatment in medical and surgical patients has been produced for South African conditions and it is hoped that this guideline will continue to improve anticoagulation practice in this country, which will directly benefit patient outcomes.
Abstract: Background. Pharmacological prophylactic anticoagulation in many countries, including South Africa, is under-prescribed, which unfortunately results in unacceptable morbidity and mortality in a substantial number of patients. Method. The Southern African Society of Thrombosis and Haemostasis reviewed the available literature as well as guidelines from other societies. Specialties represented on the committees included anaesthetics, cardiology, clinical haematology, critical care, gynaecology, haematopathology, internal medicine, neurology, orthopaedic surgery, pulmonology and vascular surgery. A draft document was produced, which was revised by consensus agreement. To avoid local bias, the guidelines were adjudicated by recognised independent international external experts. Results and conclusion. A concise, practical guideline for thrombo-prophylaxis and treatment in medical and surgical patients has been produced for South African conditions. These guidelines will hopefully lead to improved anticoagulation practice in this country, which we believe will directly benefit patient outcomes.
TL;DR: Tailored sex work interventions should explicitly include male and transgender sex workers, sex work-specific clinics, focus on the risks of unprotected anal sex, and include interventions to reduce alcohol harm.
Abstract: Background. In South Africa, information on sex workers' characteristics, sexual behaviour and health needs is limited. Current social, legal and institutional factors impede a safe working environment for sex workers and their clients.
Objectives. To describe characteristics and sexual behaviour of female, male and transgender sex workers, and assess their risk factors for unprotected sex.
Methods. Repeat cross-sectional surveys among sex workers were conducted in Hillbrow, Sandton, Rustenburg and Cape Town in 2010. Sex workers were interviewed once; any re-interviews were excluded from analysis. Unprotected sex was defined as any unprotected penetrative vaginal or anal sex with last two clients.
Results. Trained sex workers interviewed 1 799 sex workers. Sex work was a full-time profession for most participants. About 8% (126/1 594) of women, 33% (22/75) of men, and 25% (12/50) of transgender people had unprotected sex. A quarter of anal sex was unprotected. Unprotected sex was 2.1 times (adjusted odds ratio (AOR), 95% CI 1.2 - 3.7; p=0.011) more likely in participants reporting daily or weekly binge drinking than non-binge drinkers. Male sex workers were 2.9 times (AOR, 95%CI 1.6 - 5.3; p<0.001) more likely, and transgender people 2.4 times (AOR, 95% CI 1.1 - 4.9; p=0.021) more likely, than females to have unprotected sex. Sex workers in Hillbrow, where the only sex work-specific clinic was operational, were less likely to have unprotected sex than those in other sites.
Conclusion. Tailored sex work interventions should explicitly include male and transgender sex workers, sex work-specific clinics, focus on the risks of unprotected anal sex, and include interventions to reduce alcohol harm.
TL;DR: Assessment of the prevalence of latent tuberculosis infection among highly exposed HCWs and low-exposed medical students in Johannesburg, South Africa concluded that infection control strategies and occupational screening programmes for professional and lay HCWs, as well as medical students, should be implemented in all high-burden settings.
Abstract: Background . Tuberculin skin test (TST) and interferon gamma release assays (IGRAs) are both recommended for routine screening of healthcare workers (HCWs) in low tuberculosis (TB)-burden countries. More recently, based on scarce data, the World Health Organization strongly recommended that IGRA should not be used for occupational screening in high-burden settings. Objective. To assess the prevalence of latent tuberculosis infection (LTBI) determined among highly exposed HCWs and low-exposed medical students in Johannesburg, South Africa. Methods. We performed a cross-sectional study using both TSTs and IGRAs to determine the prevalence rate of LTBI in 79 medical students and 120 HCWs providing HIV and/or TB care. Results. The prevalence of LTBI among HCWs was 2- to 4-fold higher than that among medical students (56.7% v. 26.6% TST-positive; 69.2% v.15.2% IGRA-positive, respectively), with 3-fold higher odds for TST positivity and 12-fold higher odds for IGRA positivity among HCWs compared with students. Despite the perception of being at high risk, few HCWs protected themselves against LTBI. The majority of HCWs reported that they would participate in annual TST or IGRA screening. Conclusion. Infection control strategies and occupational screening programmes for professional and lay HCWs, as well as medical students, should be implemented in all high-burden settings. Further research is needed to determine whether IGRA or TST is the optimal assay for periodical screening of HCWs in high-burden settings.
TL;DR: While increasing the number of ICU beds in the public sector will open critical care services to more users, the NHI scheme would not solve the huge discrepancies of access to ICUs, and availability of critical care staff, across the provinces.
Abstract: Objective. To determine the national distribution of intensive care unit (ICU)/high care (HC) beds and the implications for ICU bed availability in the envisaged national health insurance (NHI) scheme. Methods. A descriptive, non-interventional, observational study design was used. A desk-top audit of all public and private sector ICUs, including ICU/HC beds, in South Africa was undertaken for the period 2008 - 2009. For this study, both categories were analysed and referred to as ICU beds, as they reflect the critical care component of the health service in South Africa. Results. In 2008 - 2009, there were 4 719 ICU beds in the private and public sectors in South Africa, with 75% (3 533) in the former and 25% (1 186) in the latter. The majority of ICU beds in the two sectors were located in three provinces: Gauteng (49%), KwaZulu-Natal (14%) and Western Cape (15%), representing 78% of ICU beds (3 703/4 719) and catering for 54% of the country’s population. Eastern Cape had fewer than 300 beds, North West and Mpumalanga had fewer than 150 beds, and Limpopo and Northern Cape had 66 and 47 beds respectively. With the proposed NHI scheme, the number of ICU beds available would be 4 719, which would translate into a bed:population ratio of approximately 1:10 000. However, there are large variations across the provinces, which makes the availability of this level of care in some provinces non-existent. Conclusion. While increasing the number of ICU beds in the public sector will open critical care services to more users, the NHI scheme would not solve the huge discrepancies of access to ICUs, and availability of critical care staff, across the provinces.
TL;DR: Smoking the Twisp e-cigarette may be a healthier and more acceptable alternative to smoking tobacco cigarettes.
Abstract: Background. Chronic obstructive pulmonary disease and lung cancer are diseases associated with smoking tobacco cigarettes. Smokers find cessation difficult. Objectives. To determine whether smoking the Twisp electronic cigarette (e-cigarette), containing nicotine in a vegetable-based glycerine substance, would reduce carboxyhaemoglobin (COHb) levels in regular cigarette smokers by (i) comparing arterial and venous COHb levels before and after smoking the Twisp e-cigarette for 2 weeks; and (ii) evaluating changes in participants’ perception of their health and lifestyle following the use of Twisp e-cigarettes. Methods. A single group within-subject design was used where tobacco cigarette smokers converted to Twisp e-cigarettes for 2 weeks. Prior to using the Twisp e-cigarette and after using this device for 2 weeks, arterial COHb, venous COHb and venous cotinine levels were determined. Additionally, the participants were asked to complete a questionnaire outlining their perceptions on health and lifestyle. Results. Thirteen participants of median age 38 years (range 23 - 46) with a smoking median of 20 cigarettes/day (range 12 - 30) completed the study. COHb levels (%) were significantly reduced after smoking Twisp e-cigarettes for 2 weeks (mean ± standard deviation (SD) arterial COHb before 4.66±1.99 v. after 2.46±1.35; p=0.014 and mean ±SD venous COHb before 4.37±2.1 v. after 2.50±1.23; p=0.018). There was excellent agreement between arterial and venous COHb levels (intraclass correlation coefficient 0.916). A decrease in cotinine levels (p=0.001) and an increase in oxygen saturation (p=0.002) were also observed. The majority of participants perceived improvements in their health and lifestyle parameters. Conclusion. Smoking the Twisp e-cigarette may be a healthier and more acceptable alternative to smoking tobacco cigarettes.
TL;DR: These surveys demonstrate that the comprehensive and inter-sectorial tobacco control health promotion strategies implemented in SA have led to a gradual reduction in cigarette use amongst school learners.
Abstract: Background. The South African (SA) government has implemented comprehensive tobacco control measures in line with the requirements of the Framework Convention on Tobacco Control. The effect of these measures on smoking prevalence and smoking-related attitudes, particularly among young people, is largely unknown. Objective. To describe the impact of a comprehensive health promotion approach to tobacco control amongst SA school learners. Methods. Four successive cross-sectional Global Youth Tobacco Surveys (GYTSs) were conducted in 1999, 2002, 2008 and 2011 among nationally representative samples of SA grades 8 - 10 school learners. We assessed the prevalence of current smoking (having smoked a cigarette on ≥1 day in the 30 days preceding the survey) and smoking-related attitudes and behaviours. Results. Over the 12-year survey period current smoking among learners declined from 23.0% (1999) to 16.9% (2011) – a 26.5% reduction. Reductions in smoking prevalence were less pronounced amongst girls and amongst black learners. We observed an increase in smoking prevalence amongst learners between 2008 and 2011. Smoking-related attitudes and behaviours showed favourable changes over the survey period. Conclusion. These surveys demonstrate that the comprehensive and inter-sectorial tobacco control health promotion strategies implemented in SA have led to a gradual reduction in cigarette use amongst school learners. Of concern, however, are the smaller reductions in smoking prevalence amongst girls and black learners and an increase in smoking prevalence from 2008 to 2011. Additional efforts, especially for girls, are needed to ensure continued reduction in smoking prevalence amongst SA youth.
TL;DR: The principles for developing National Health Insurance (NHI) as described in the Green Paper are to improve access to quality healthcare services for the whole population and to provide financial risk protection against health-related catastrophic expenditures as discussed by the authors.
Abstract: The principles for developing National Health Insurance (NHI) as described in the Green Paper are to improve access to quality healthcare services for the whole population and to provide financial risk protection against health-related catastrophic expenditures (Table 1). Comprehensive healthcare will be provided through accredited and contracted public and private providers, with a strong focus on health promotion and prevention services at the community and household level. The first 5 years will focus on strengthening the public sector in preparation for new NHI systems, with the launch of the new central NHI fund envisaged in 2014/15. We review progress since the Green Paper was launched in August 2011, and summarise a more in-depth review just completed.
TL;DR: Today there are very few localities on the African continent where populations of vector mosquitoes are still susceptible to the approved classes of insecticides and if elimination is to be achieved, SA needs to invest more resources into malaria control.
Abstract: Malaria vector control is primarily insecticide based and relies on indoor residual spraying (IRS) and the distribution of long-lasting insecticide-treated bednets (LLINs). These interventions have generally proved effective where appropriately implemented. However, the increasing incidence of insecticide resistance in target vector populations can, and in several cases already has, undermined the effectiveness of IRS and LLINs. Today there are very few localities on the African continent where populations of vector mosquitoes are still susceptible to the approved classes of insecticides. If elimination is to be achieved, SA needs to invest more resources into malaria control.
TL;DR: A number of perceived barriers to student research were identified including a lack of adequate training, time and research opportunities and few had been involved in voluntary research and produced work worthy of presentation and/or publication.
Abstract: Background. The workforce of ‘physician-scientists’ is ageing and decreasing in numbers. The responsibility to combat this trend rests on future generations of healthcare professionals and it is therefore valuable to evaluate medical students’ attitudes towards research. Objective. To establish the attitudes of University of Cape Town (UCT) medical students towards research and to investigate the factors influencing these attitudes. Methods. An anonymous, cross-sectional, self-administered questionnaire was administered to medical students from years 1 to 6 studying medicine at UCT in 2011. Questions were primarily closed-ended and consisted of Likert scales. Results. Out of a population of 1 195 medical students, 733 were sampled (63%); 65% were female, 53% were preclinical students (years 1 - 3) and 47% were in their clinical years (year 4 - 6). Overall, 61% of students had a positive attitude towards research and 74% felt that participation in research was important to their medical school education; 22% had been involved in voluntarily extracurricular research, 4% had presented at a scientific meeting and 3% had published in peer-reviewed journals. A number of perceived barriers to student research were identified including a lack of adequate training, time and research opportunities. Conclusion. Students believed that research was important and had a positive attitude towards it. However, few had been involved in voluntary research and produced work worthy of presentation and/or publication. Addressing identified barriers and improving students’ attitudes may begin to reverse the trend in declining numbers of physician-scientists.
TL;DR: Rural origin is identified as an independent indicator of poor outcome in acute appendicitis in urban and rural patients in KwaZulu-Natal and may include difficulty in accessing the health system or delay in transfer to a regional hospital.
Abstract: Background. Acute appendicitis in South Africa is associated with higher morbidity than in the developed world. Objective. To compare outcomes of urban and rural patients in KwaZulu-Natal and to determine whether there are disparities in outcome. Methods. We conducted a prospective study from September 2010 to September 2012 at Edendale Hospital in Pietermaritzburg, South Africa. All patients who presented with acute appendicitis were included. The operative and clinical course of urban and rural patients was compared. Results. A total of 500 patients were included, with 200 patients in the rural group and 300 in the urban group. Those from the rural group had a significantly longer duration of symptoms prior to presentation. All septic parameters were significantly worse in the rural group. Significantly more patients from the rural group required a laparotomy (77% v. 51% urban; p<0.001). Inflamed, non-perforated appendicitis was more commonly seen in the urban group (52.3% v. 21% rural; p<0.001), while perforated appendicitis was much more common in the rural group (79% v. 47.7% urban; p<0.001). Perforation associated with generalised, four-quadrant intra-abdominal contamination was significantly higher in the rural group than the urban group (60.5% v. 21%, respectively; p<0.05). Significantly more patients from the rural group required an open abdomen (46% v. 12% urban; p<0.001) and ≥1 re-laparotomies to control severe intra-abdominal sepsis (60.5% v. 23.3% urban; p<0.001). Conclusion. We have identified rural origin as an independent indicator of poor outcome. Possible reasons may include difficulty in accessing the health system or delay in transfer to a regional hospital. These need to be investigated further.
TL;DR: When combined with regular bacterial surveillance, antimicrobial stewardship allows accurate empiric antimicrobial prescription with minimal need for ultrabroad-spectrum combination therapy, which can potentially reduce the emergence of multidrug-resistant pathogens.
Abstract: Background. Nosocomial infections are a major cause of morbidity in the critically injured, and the incidence of resistant strains of bacteria is increasing. Management requires a strategy that achieves accurate empiric cover without antibiotic overuse − a goal that may be achieved by surveillance and antibiotic stewardship. Objectives. With the aim of minimising the use of empirical ultrabroad-spectrum combination antimicrobial prescriptions and reducing bacterial resistance, the level I Trauma Intensive Care Unit (TICU) at Inkosi Albert Luthuli Central Hospital (IALCH) in Durban employs stewardship and an antimicrobial policy based on surveillance. This study was undertaken with three aims: (i) to describe the spectrum and sensitivities of nosocomial pathogens in a level I TICU; (ii) to ascertain, based on surveillance data, how frequently initial empiric choice of antimicrobials was correct; and (iii) to determine how frequently ultrabroad-spectrum antimicrobials were prescribed and were actually necessary. Methods. Over a 12-month period, all critically injured patients who underwent mechanical ventilation in the TICU were identified from a prospectively gathered database. Information regarding every specimen submitted to the National Health Laboratory Services (NHLS) situated at IALCH was extracted from the laboratory computer database. For each patient, bacterial isolates and antimicrobial susceptibility were identified using standard laboratory techniques. Empiric prescriptions for presumed nosocomial sepsis were identified from the hospital’s computerised patient record system and compared with culture results. Acinetobacter species were regarded as colonisers and treatment not offered unless this was the sole isolate in the presence of signs of severe sepsis. Results. Of 227 patients, 106 (46.6%) had 136 culture-positive isolates with a total of 323 pathogens (201 Gram-negative, 119 Grampositive, 3 Candida albicans). There were 19 species of Gram-negative pathogens, of which 56% comprised Enterobacteriaceae. Extended spectrum beta-lactamase (ESBL) production was found in 6/31 (19%) Escherichia coli coli and 6/24 (25%) Klebsiella isolates. Staphyloccocal species accounted for 60% of the Gram-positive isolates, of which 18 were methicillin-resistant Staphylococcus aureus (MRSA). All Candida isolates were sensitive to fluconazole. One hundred and one empiric and 14 directed prescriptions were issued. Despite positive cultures, antimicrobials were not prescribed for 21 patients who had no evidence of sepsis. Excluding multidrug-resistant Acinetobacter isolates, there were 87 (93.5%) appropriate and 6 (6.5%) incorrect prescriptions. Ultrabroad-spectrum combination therapy (U-bSCT) was employed for 11 patients but was necessary in only 2. Conclusions. When combined with regular bacterial surveillance, antimicrobial stewardship allows accurate empiric antimicrobial prescription with minimal need for ultrabroad-spectrum combination therapy. This policy can potentially reduce the emergence of multidrug-resistant pathogens, precluding the need for broad-spectrum antimicrobials and the attendant problems of overuse.
TL;DR: The evidence and appropriate context of SCS delivery, and recommendations for patient selection and appropriate use are discussed, and the possible complications following SCS are described.
Abstract: Spinal cord stimulation (SCS) is an accepted method of pain control. SCS has been used for many years and is supported by a substantial evidence base. A multidisciplinary consensus group has been convened to create a guideline for the implementation and execution of an SCS programme for South Africa (SA). This article discusses the evidence and appropriate context of SCS delivery, and makes recommendations for patient selection and appropriate use. The consensus group has also described the possible complications following SCS. This guideline includes a literature review and a summary of controlled clinical trials of SCS. The group notes that, in SA, SCS is performed mainly for painful neuropathies, failed back surgery, and chronic regional pain syndrome. It was noted that SCS is used to treat other conditions such as angina pectoris and ischaemic conditions, which have therefore been included in this guideline. These recommendations give guidance to practitioners delivering this treatment, to those who may wish to refer patients for SCS, and to those who care for patients with stimulators in situ. The recommendations also provide a resource for organisations that fund SCS. This guideline has drawn on the guidelines recently published by the British Pain Society, and parts of which have been reproduced with the society's permission. These recommendations have been produced by a consensus group of relevant healthcare professionals. Opinion from outside the consensus group has been incorporated through consultation with representatives of all groups for whom these recommendations have relevance. The recommendations refer to the current body of evidence relating to SCS. The consensus group wishes to acknowledge and thank the task team of the British Pain Society for their help and input into this document.
TL;DR: This study describes the prevalence of overweight and obesity, wasting and stunting of female learners in KZN and suggests the presence of a nutritional transition in these rural communities; however, further studies are needed.
Abstract: Background. Malnutrition substantially impacts the health outcomes of children. Globally, the childhood prevalence of overweight and obesity has increased, while underweight and stunting (though decreasing) continues to pose a major public health challenge. In low- to middle-income countries, a mixed pattern of over- and undernutrition (nutritional transition) can exist in communities. Objective. To describe the prevalence of malnutrition among female learners in the Nongoma and Ceza districts in Zululand, KwaZuluNatal (KZN). Methods. We performed a secondary analysis of anthropometric data collected during the 2011 HPV Vaccination Demonstration Project. School health teams, comprising trained nurses, measured the height (in cm) and weight (in kg) of 963 female learners in 31 primary schools. Internationally accepted standardised measures were used as cut-offs for defining overweight, obesity, underweight and stunting. Results. We found evidence of both under- and overnutrition. Overall, 9% of female learners were overweight, 3.8% obese, 4% underweight and 9.2% stunted (using WHO/NCHS criteria). The highest levels of stunting were in the 11 - 12-year age groups, of underweight in the 10-year age group, of overweight and obesity in the 9 - 10-year age groups. Moreover, a proportion of underweight (17.4%), overweight (11.1%) and obese (22.9%) learners were also stunted. Conclusion. Our study describes the prevalence of overweight and obesity, wasting and stunting of female learners in KZN and suggests the presence of a nutritional transition in these rural communities; however, further studies are needed. Our findings emphasise the need for health promotion and education programs in schools.
TL;DR: There was a high prevalence of cholesteatoma, hearing loss and other complications in children in this study, and most cases of CSOM were due to quinolone-sensitive Gram-negative aerobes.
Abstract: Background. Chronic suppurative otitis media (CSOM) is a chronic infection of the middle ear cleft. In sub-Saharan Africa >50% of cases occur in children <10 years of age. Objectives. To describe the otological, audiological and bacteriological findings in children with CSOM. Methods. We conducted a prospective study at the Ear, Nose and Throat (ENT) Clinic at Universitas Academic Hospital between August 2009 and December 2010. We included all children with CSOM over this period. Patients underwent ENT and paediatric examination, and were tested for HIV. Pus swabs were taken after an ear toilet for routine microbiology, fungal and Mycobacterium tuberculosis culture. We performed audiological testing after the otorrhoea had resolved. Results. Eighty-six children (113 ears) were included, with a median age of 4.6 years (range 1 - 12 years). The mean duration of otorrhoea was 161.7 weeks (range 4 - 572 weeks). Nine patients (10.5%) presented with coalescent mastoiditis and/or intracranial complications of CSOM. Of the 153 organisms identified; Gram-negative bacteria were present in 93 (82.3%) ears, with 94.8% of these being sensitive to quinolones. Only 1 case of tuberculous otitis media was identified. HIV infection was present in 54.6% of patients tested. There was a hearing loss in 44 (66.7%) of the tested affected ears. Conclusions. There was a long delay between the onset of symptoms and accessing ENT services. Most cases of CSOM were due to quinolone-sensitive Gram-negative aerobes. There was a high prevalence of cholesteatoma, hearing loss and other complications in children in this study.
TL;DR: The study suggests that the prevalence of FAS may be very high in isolated communities, or in particular hot-spots, and adds to the growing evidence that FAS/PFAS is a significant, and underestimated, health problem in South Africa.
Abstract: Background. Fetal alcohol syndrome (FAS) is common in parts of South Africa; rural residence is a frequently cited risk factor. We conducted a FAS school prevalence survey of an isolated rural community in a West Coast village of Western Cape Province, so obtaining the first directly measured rate, focusing specifically on a South African rural area, of FAS and partial FAS (PFAS). Methods. The study area (Aurora village), a community of about 2 500 people in a grain-producing region, has one primary school. All learners were eligible for study inclusion. Initial anthropometry screening was followed by a diagnostic stage entailing examination by a dysmorphologist for features of FAS, neurodevelopmental assessment, and an interview assessing maternal alcohol consumption. Results. Of 160 learners screened, 78 (49%) were screen-positive, of whom 63 (81%) were clinically assessed for FAS. The overall FAS/PFAS rate among the screened learners was 17.5% (95% confidence interval 12.0 - 24.2%), with 16 (10.0%) children having FAS and 12 (7.5%) PFAS. High rates of stunting, underweight and microcephaly were noted in all learners, especially those with FAS or PFAS. Five (18%) mothers of affected children were deceased by the time of assessment. Conclusion. We describe very high rates of FAS/PFAS in an isolated rural part of the Western Cape that is not located in a viticultural region. Our study suggests that the prevalence of FAS may be very high in isolated communities, or in particular hot-spots. It adds to the growing evidence that FAS/PFAS is a significant, and underestimated, health problem in South Africa. Expanded screening and surveillance programmes, and preventive interventions, are urgently needed.
TL;DR: This study provides relevant data for the empirical treatment of community-acquired UTIs in SA and identifies UTI pathogens less susceptible to amoxicillin/clavulanic acid when compared with fluoroquinolones and fosfomycin.
Abstract: Background. Patients with community-acquired urinary tract infections (UTIs) frequently present to healthcare facilities in South Africa (SA). Aim. To provide information on UTI aetiology and antimicrobial susceptibility of pathogens. Methods. We recruited women with UTI-related symptoms, who tested positive for ≥2 urine dipstick criteria (proteinuria, blood, leucocytes or nitrites) at 1 public and 5 private primary healthcare facilities in 2011. Demographic and clinical data were recorded and mid-stream urine (MSU) specimens were cultured. UTI pathogens were Gram-stained and identified to species level. Etest-based antimicrobial susceptibility testing was performed for amoxicillin/clavulanic acid, cefixime, cefuroxime, ciprofloxacin, fosfomycin, levofloxacin, nitrofurantoin, norfloxacin and trimethoprim/sulphamethoxazole. Results. Of the 460 women recruited, 425 MSU samples were processed and 204 UTI pathogens were identified in 201 samples. Most pathogens were Gram-negative bacilli (GNB) (182; 89.2%) and 22 (10.8%) were Gram-positive cocci (GPC). Escherichia coli was the most frequent GNB (160; 79.6%), while Enterococcus faecalis was the predominant GPC (8; 4.0%). The UTI pathogens had similar susceptibility profiles for fosfomycin (95.5%; 95% confidence interval (CI) 92.6 - 98.4), the 3 fluoroquinolones (94.1%; 95% CI 90.8 - 97.4), nitrofurantoin (91.7%; 95% CI 87.8 - 95.6), cefuroxime (90.1%; 95% CI 86.0 - 94.3) and cefixime (88.2%; 95% CI 83.7 - 92.6). UTI pathogens were less susceptible to amoxicillin/clavulanic acid (82.8%; 95% CI 77.5 - 88.0) when compared with fluoroquinolones and fosfomycin. Trimethoprim/ sulphamethoxazole was the least efficacious antimicrobial agent (44.3% susceptible; 95% CI 37.4 - 51.2). Conclusion. This study provides relevant data for the empirical treatment of community-acquired UTIs in SA.
TL;DR: In this article, the authors examined whether household poverty, orphanhood and parental illness (by AIDS or other causes) independently or interactively predict child health, developmental and HIV-infection risks.
Abstract: Background. Identifying children at the highest risk of negative health effects is a prerequisite to effective public health policies in Southern Africa. A central ongoing debate is whether poverty, orphanhood or parental AIDS most reliably indicates child health risks. Attempts to address this key question have been constrained by a lack of data allowing distinction of AIDS-specific parental death or morbidity from other causes of orphanhood and chronic illness. Objectives. To examine whether household poverty, orphanhood and parental illness (by AIDS or other causes) independently or interactively predict child health, developmental and HIV-infection risks. Methods. We interviewed 6 002 children aged 10 - 17 years in 2009 - 2011, using stratified random sampling in six urban and rural sites across three South African provinces. Outcomes were child mental health risks, educational risks and HIV-infection risks. Regression models that controlled for socio-demographic co-factors tested potential impacts and interactions of poverty, AIDS-specific and other orphanhood and parental illness status. Results. Household poverty independently predicted child mental health and educational risks, AIDS orphanhood independently predicted mental health risks and parental AIDS illness independently predicted mental health, educational and HIV-infection risks. Interaction effects of poverty with AIDS orphanhood and parental AIDS illness were found across all outcomes. No effects, or interactions with poverty, were shown by AIDS-unrelated orphanhood or parental illness. Conclusions. The identification of children at highest risk requires recognition and measurement of both poverty and parental AIDS. This study shows negative impacts of poverty and AIDS-specific vulnerabilities distinct from orphanhood and adult illness more generally. Additionally, effects of interaction between family AIDS and poverty suggest that, where these co-exist, children are at highest risk of all.
TL;DR: This document contextualise, for South Africa, practice guidelines for the management of chronic hepatitis B and draws on a number of global societies' guidelines, which draws on these guidelines and serves to contextualise the challenge in South Africa remains prevention through the universal vaccination coverage of all children and the identification of those with Chronic hepatitis B virus infection.
Abstract: Hepatitis B remains a significant yet preventable health issue in South Africa. The introduction of the hepatitis B vaccine into the country some 18 years ago has demonstrated benefit, but the exposure to, and prevalence of chronic HBsAg positivity remain unacceptably high. Those with chronic hepatitis B virus infection have an elevated risk of developing cirrhosis with end-stage liver disease and a markedly elevated risk of hepatocellular carcinoma, independent of the presence of cirrhosis. The challenge in South Africa remains prevention through the universal vaccination coverage of all children and the identification of those with chronic hepatitis B virus infection. Over the last decade our understanding of hepatitis B and its behaviour and natural history in those with chronic infection has significantly improved. This understanding is key to identifying those who warrant further evaluation and therapy. A number of global societies have updated their guidelines in recent years. This document draws on these guidelines and serves to contextualise, for South Africa, practice guidelines for the management of chronic hepatitis B.
TL;DR: The 2-year internship has provided the basis for independent medical practice in DHs, however, certain critical skill gaps need urgent attention, particularly in obstetrics and anaesthesia.
Abstract: Background. The 2-year internship period for medical graduates began in South Africa in 2005 and has never been formally evaluated. Objective. This study assessed the perceptions of community service medical officers (COSMOs) working at district hospitals (DHs) in KwaZulu-Natal (KZN) to determine whether the 2-year internship programme had adequately prepared them for community service (CS). Method. A cross-sectional descriptive study was conducted regarding the perceptions of COSMOs working at 22 district hospitals in KZN. Data were collected in July 2012, using a questionnaire based on the core skills and knowledge detailed in the Health Professions Council of South Africa intern log book. All eight domains were self-assessed and a score of 4 out of 5 indicated an ability to work independently. Results. Of the COSMOs, 78% (60 out of 89) completed the questionnaire. Most felt well-prepared for CS in all disciplines, but critical gaps in knowledge and skills were identified in paediatrics, orthopaedics, anaesthetics and obstetrics. In addition, 75% of respondents (45 out of 60) expressed a need for additional training in the disciplines of ear, nose and throat (ENT), urology, ophthalmology and dermatology. Conclusion. The 2-year internship has provided the basis for independent medical practice in DHs. However, certain critical skill gaps need urgent attention, particularly in obstetrics and anaesthesia. Areas of weakness in ENT, urology, ophthalmology and dermatology could be addressed by including these specialities as a compulsory rotation in surgery, medicine or family medicine during internship training.
TL;DR: Obesity and tobacco use are associated with significantly increased healthcare expenditure and severe obesity doubles these excess costs.
Abstract: Background. Health risks such as tobacco use, excessive alcohol consumption and unhealthy body weight contribute to the development of chronic health problems. Objective. To estimate the associations of tobacco use, excessive alcohol consumption and obesity with healthcare expenditure and chronic diseases among South Africans on a comprehensive medical scheme. Methods. We performed a cross-sectional analysis of health survey and medical claims data for 70 000 South Africans during 2010. Results. Moderately obese individuals, with a body mass index (BMI) of 30 - 35 kg/m 2 averaged R2 300 (11%) higher annual medical expenditure in the year 2010 than never-smokers with a BMI 35 kg/m 2 ), however, had increased healthcare costs of R4 400 (23% increase). This exceeds the difference between a 40- and a 50-year-old (increase of R3 200). Being overweight or excessive consumption of alcohol was not significantly associated with medical expenditures. Absolute and relative excess expenditures associated with these health risks are higher among older individuals. In the 54 - 69-year age group, estimated additional expenses were R6 200 for smoking (20% increase over never-smokers with BMI <30 kg/m 2 ), R6 600 for moderate obesity (21%) and R15 800 for severe obesity (51% increase). Overweight or heavy drinking was not statistically significantly associated with healthcare expenditure. Conclusion. Obesity and tobacco use are associated with significantly increased healthcare expenditure. Severe obesity doubles these excess costs.
