Setting ART initiation targets in response to changing guidelines : The importance of addressing both steady-state and backlog

PKBackground: Target setting is useful in planning, assessing and improving antiretroviral treatment (ART) programmes. In the past 4 years, the ART initiation environment has been transformed due to the change in eligibility criteria (starting ART at a CD4+ count <350 cells/μl v. <200 cells/μl) and the roll-out of nurse-initiated management of ART. Objective: To describe and illustrate the use of a target-setting model for estimating district-based targets in the era of an expanding ART programme and changing CD4+ count thresholds for ART initiation. Method: Using previously described models and data for annual new HIV infections, we estimated both steady-state need for ART initiation and backlog in a North West Province district, accounting for the shift in eligibility. Comparison of actual v. targeted ART initiations was undertaken. The change in CD4+ count threshold adds a once-off group of newly eligible patients to the pool requiring ART – the backlog. The steady-state remains unchanged as it is determined by the annual rate of new HIV infections in previous years. Results: The steady-state need for the district was 639 initiations/month, and the backlog was ~15 388 patients. After the shift in eligibility in September 2011, the steady-state target was exceeded over several months with some backlog addressed. Of the total backlog for this district, 72% remains to be cleared. Conclusion: South Africa has two pools of patients who need ART: the steady-state of HIV-infected patients entering the programme each year, determined by historical infection rates; and the backlog created by the shift in eligibility. The healthcare system needs to build longterm capacity to meet the steady-state need for ART and additional capacity to address the backlog

Globalisation, neo-liberalism and vocational learning: the case of English further education colleges

Further education (FE) has traditionally been a rather unspectacular activity. Lacking the visibility of schools or the prestige of universities, for the vast majority of its existence FE has had a relatively low profile on the margins of English education. Over recent years this situation has altered significantly and further education has undergone profound change. This paper argues that a combination of related factors – neo-liberalism, globalisation, and dominant discourses of the knowledge economy – has acted in synergy to transform FE into a highly performative and marketised sector. Against this backdrop, further education has been assigned a particular role based upon certain narrow and instrumental understandings of skill, employment and economic competitiveness. The paper argues that, although it has always been predominantly working class in nature, FE is now, more than ever, positioned firmly at the lower end of the institutional hierarchy in the highly class-stratified terrain of English education

Automated Classification of Breast Cancer Stroma Maturity from Histological Images

OBJECTIVE: The tumour microenvironment plays a crucial role in regulating tumour progression by a number of different mechanisms, in particular the remodelling of collagen fibres in tumour-associated stroma, which has been reported to be related to patient survival. The underlying motivation of this work is that remodelling of collagen fibres gives rise to observable patterns in Hematoxylin and Eosin (H&E) stained slides from clinical cases of invasive breast carcinoma that the pathologist can label as mature or immature stroma. The aim of this paper is to categorise and automatically classify stromal regions according to their maturity and show that this classification agrees with that of skilled observers, hence providing a repeatable and quantitative measure for prognostic studies. METHODS: We use multi-scale Basic Image Features (BIF) and Local Binary Patterns (LBP), in combination with a random decision trees classifier for classification of breast cancer stroma regions-ofinterest (ROI). RESULTS: We present results from a cohort of 55 patients with analysis of 169 ROI. Our multi-scale approach achieved a classification accuracy of 84%. CONCLUSION: This work demonstrates the ability of texture-based image analysis to differentiate breast cancer stroma maturity in clinically acquired H&E stained slides at least as well as skilled observers

Comparing laboratory costs of smear/culture and Xpert(®) MTB/RIF-based tuberculosis diagnostic algorithms

SETTING: Cape Town, South Africa, where Xpert® MTB/RIF was introduced as a screening test for all presumptive tuberculosis (TB) cases. OBJECTIVE: To compare laboratory costs of smear/culture- and Xpert-based tuberculosis (TB) diagnostic algorithms in routine operational conditions. METHODS: Economic costing was undertaken from a laboratory perspective, using an ingredients-based costing approach. Cost allocation was based on reviews of standard operating procedures and laboratory records, timing of test procedures, measurement of laboratory areas and manager interviews. We analysed laboratory test data to assess overall costs and cost per pulmonary TB and multidrug-resistant TB (MDR-TB) case diagnosed. Costs were expressed as 2013 Consumer Price Index-adjusted values. RESULTS: Total TB diagnostic costs increased by 43%, from US$440 967 in the smear/culture-based algorithm (April–June 2011) to US$632 262 in the Xpert-based algorithm (April–June 2013). The cost per TB case diagnosed increased by 157%, from US$48.77 (n = 1601) to US$125.32 (n = 1281). The total cost per MDR-TB case diagnosed was similar, at US$190.14 and US$183.86, with 95 and 107 cases diagnosed in the respective algorithms. CONCLUSION: The introduction of the Xpert-based algorithm resulted in substantial cost increases. This was not matched by the expected increase in TB diagnostic efficacy, calling into question the sustainability of this expensive new technology

Addressing challenges in scaling up TB and HIV treatment integration in rural primary healthcare clinics in South Africa (SUTHI): a cluster randomized controlled trial protocol

Background A large and compelling clinical evidence base has shown that integrated TB and HIV services leads to reduction in human immunodeficiency virus (HIV)- and tuberculosis (TB)-associated mortality and morbidity. Despite official policies and guidelines recommending TB and HIV care integration, its poor implementation has resulted in TB and HIV remaining the commonest causes of death in several countries in sub-Saharan Africa, including South Africa. This study aims to reduce mortality due to TB-HIV co-infection through a quality improvement strategy for scaling up of TB and HIV treatment integration in rural primary healthcare clinics in South Africa. Methods The study is designed as an open-label cluster randomized controlled trial. Sixteen clinic supervisors who oversee 40 primary health care (PHC) clinics in two rural districts of KwaZulu-Natal, South Africa will be randomized to either the control group (provision of standard government guidance for TB-HIV integration) or the intervention group (provision of standard government guidance with active enhancement of TB-HIV care integration through a quality improvement approach). The primary outcome is all-cause mortality among TB-HIV patients. Secondary outcomes include time to antiretroviral therapy (ART) initiation among TB-HIV co-infected patients, as well as TB and HIV treatment outcomes at 12 months. In addition, factors that may affect the intervention, such as conditions in the clinic and staff availability, will be closely monitored and documented. Discussion This study has the potential to address the gap between the establishment of TB-HIV care integration policies and guidelines and their implementation in the provision of integrated care in PHC clinics. If successful, an evidence-based intervention comprising change ideas, tools, and approaches for quality improvement could inform the future rapid scale up, implementation, and sustainability of improved TB-HIV integration across sub-Sahara Africa and other resource-constrained settings.

Safeguarding children in dentistry: 1. Child protection training, experience and practice of dental professionals with an interest in paediatric dentistry

* Few dental professionals with child protection training have experience of making referrals. * There is a wide gap in practice between recognising signs of child abuse and neglect and responding effectively. * This may indicate missed opportunities to save children from continuing abuse. * There is a need for improved child protection information, support and training for dental professionals. Abstract Following several highly publicised inquiries into the deaths of children from abuse and neglect, there has been much recent interest in the role and responsibility of all health professionals to protect children at risk of maltreatment. The findings of a postal questionnaire, sent in March 2005 to 789 dentists and dental care professionals with an interest in paediatric dentistry working in varied settings in the UK, are presented in a two-part report and discussed in the context of current multi-agency good practice in safeguarding and promoting the welfare of children. This first part explores reported child protection training, experience and practice. There was a significant gap between recognising signs of abuse and responding effectively: 67% of respondents had suspected abuse or neglect of a child patient at some time in their career but only 29% had ever made a child protection referral. The dental profession is alerted to the need to ensure necessary appropriate action to safeguard children is always taken when child abuse or neglect are suspected

Barriers to HIV Care and Treatment by Doctors: A review of the literature.

This paper provides a review of the reported barriers that prevent doctors from managing HIV infected patients. The four most commonly reported barriers were: fear of contagion, fear of losing patients, unwillingness to care, and inadequate knowledge /training about treating HIV patients. Barriers to treating HIV infected patients is frequently reported in many countries and it is important for developing countries such as South Africa to learn from these experiences by identifying local problems so that constructive interventions and strategies can be developed to address these barriers, thereby improving the quality of patient care. Further research in respect of the local situation is required.IntroductionOver the last two decades acquired immunodeficiency syndrome (AIDS) has emerged as one of the most serious public health problems in the world, and by the end of 2003 it was estimated that 5.3 million South Africans were human immunodeficiency virus (HIV) positive, which corresponds to 21.5% of the population.1 In the early phase of the HIV epidemic few doctors saw infected patients and treatment options were limited. As a result many doctors were reluctant to provide care to HIV infected patients and homophobia amongst doctors, fear of contact with patients and unwillingness to care were frequently reported.2 However, there has been an exponential increase in the number of HIV and AIDS related cases and more doctors are encountering infected individuals. This review summarizes our current knowledge of barriers to treatment of HIV infected patients by doctors.MethodA comprehensive literature review was undertaken by searching the MEDLINE database, Psychlit, ISI Web, EBSCOHost, and Sabinet on line, for English language literature published between 1985 and 2004. The database search terms included keywords such as fear/s, barrier/s, concern, HIV, AIDS, attitudes, physician/s (doctor/s), practice, treatment, care and knowledge. A variety of combinations of these words were entered. All duplicate articles were removed and only studies that used doctors as the sample population were considered. Titles expressing comment, news items, opinion pieces or letters were rejected.ResultsThirty two relevant studies were identified from the literature search. The four most commonly reported barriers were: fear of contagion, fear of losing patients, unwillingness to care, and inadequate knowledge /training about treating HIV patients.Keywords: barriers; fear; knowledge; doctors; losing patientsFor full text, click here:SA Fam Pract 2006;48(2):55-55

Focus group discussion with private sector doctors in the eThekwini Metro of KwaZulu-Natal on the management of HIV/AIDS patients

Background: Highly active antiretroviral treatment (HAART) is essential in the treatment of HIV/AIDS; however, a holistic approach to HIV/AIDS management is important. This study was done to confirm the findings of two studies done previously in the eThekwini Metro of KwaZulu-Natal on private sector doctors’ management of HIV-infected patients and to obtain more in-depth information about their nonpharmacological management of HIV-infected patients.Methods: Two focus group discussions were conducted amongst private sector doctors in the eThekwini Metro, after obtaining their consent. The focus group sessions were scripted, audio-taped and transcribed verbatim. Prevalent themes were identified and reported.Results: Eight doctors participated. Of the total patient population seen annually by the majority of the doctors, an average of 43.8% was HIV infected. Doctors in this study managed their patients both pharmacologically and nonpharmacologically. Seventy-five per cent of doctors indicated that the taste of medicine played an important role in nonadherence to treatment, but all agreed that cultural beliefs also influenced the patient’s adherence to medication. Theft of medicines and the outof-stock situation prevented antiretroviral drug access, which impacted negatively on adherence. Five doctors mentioned that depressed patients abused alcohol, resulting in nonadherence. One doctor reported that he used the biopsychosocial approach to improve adherence in his patients. Doctors indicated that the disability grant given by the South African Government caused patients not to adhere to treatment in order to maintain a CD4 count of 200 or less so as to qualify for the grant.Conclusions: The study confirmed the previous study findings in that it showed that private sector doctors manage their HIV-infected patients both pharmacologically and nonpharmacologically. It further provided new and interesting information with regard to the nonpharmacological methods employed in HIV/AIDS management, that is the incorporation of culturalbeliefs in the management of HIV-infected patients to improve adherence to treatment, and the role of the disability grant and pharmaceutical formulations in contributing to nonadherence by HIV-infected patients.Keywords: focus group; private sector doctors; HIV/AIDS; cultural; biopsychosocial; adherenc

Comparing multidrug-resistant tuberculosis patient costs under molecular diagnostic algorithms in South Africa

SETTING: Ten primary health care facilities in Cape Town, South Africa, 2010–2013. OBJECTIVE: A comparison of costs incurred by patients in GenoType® MDRTBplus line-probe assay (LPA) and Xpert® MTB/RIF-based diagnostic algorithms from symptom onset until treatment initiation for multidrug-resistant tuberculosis (MDR-TB). METHODS: Eligible patients identified from laboratory and facility records were interviewed 3–6 months after treatment initiation and a cost questionnaire completed. Direct and indirect costs, individual and household income, loss of individual income and change in household income were recorded in local currency, adjusted to 2013 costs and converted to $US. RESULTS: Median number of visits to initiation of MDR-TB treatment was reduced from 20 to 7 (P < 0.001) and median costs fell from US$68.1 to US$38.3 (P = 0.004) in the Xpert group. From symptom onset to being interviewed, the proportion of unemployed increased from 39% to 73% in the LPA group (P < 0.001) and from 53% to 89% in the Xpert group (P < 0.001). Median household income decreased by 16% in the LPA group and by 13% in the Xpert group. CONCLUSION: The introduction of an Xpert-based algorithm brought relief by reducing the costs incurred by patients, but loss of employment and income persist. Patients require support to mitigate this impact
