    Antibiotics for the primary prevention of acute rheumatic fever: a meta-analysis
    (BioMed Central Ltd, 2005) Robertson, Katharine; Volmink, Jimmy; Mayosi, Bongani
    BACKGROUND:Rheumatic fever continues to put a significant burden on the health of low socio-economic populations in low and middle-income countries despite the near disappearance of the disease in the developed world over the past century. Antibiotics have long been thought of as an effective method for preventing the onset of acute rheumatic fever following a Group-A streptococcal (GAS) throat infection; however, their use has not been widely adopted in developing countries for the treatment of sore throats. We have used the tools of systematic review and meta-analysis to quantify the effectiveness of antibiotic treatment for sore throat, with symptoms suggestive of group A streptococcal (GAS) infection, for the primary prevention of acute rheumatic fever. METHODS: Trials were identified through a systematic search of titles and abstracts found in the Cochrane Central Register of Controlled Trials (Cochrane Library Issue 4, 2003), MEDLINE (1966-2003), EMBASE (1966-2003), and the reference lists of identified studies. The selection criteria included randomised or quasi-randomised controlled trials comparing the effectiveness of antibiotics versus no antibiotics for the prevention of rheumatic fever in patients presenting with a sore throat, with or without confirmation of GAS infection, and no history of rheumatic fever. RESULTS: Ten trials (n = 7665) were eligible for inclusion in this review. The methodological quality of the studies, in general, was poor. All of the included trials were conducted during the period of 1950 and 1961 and in 8 of the 10 trials the study population consisted of young adult males living on United States military bases. Fixed effects, meta-analysis revealed an overall protective effect for the use of antibiotics against acute rheumatic fever of 70% (RR = 0.32; 95% CI = 0.21-0.48). The absolute risk reduction was 1.67% with an NNT of 53. When meta-analysis was restricted to include only trials evaluating penicillin, a protective effect of 80% was found (Fixed effect RR = 0.20, 95% CI = 0.11-0.36) with an NNT of 60. The marginal cost of preventing one case of rheumatic fever by a single intramuscular injection of penicillin is approximately US$46 in South Africa. CONCLUSION: Antibiotics appear to be effective in reducing the incidence of acute rheumatic fever following an episode of suspected GAS pharyngitis. This effect may be achieved at relatively low cost if a single intramuscular penicillin injection is administered.

    Assessing the impact of a waiting time survey on reducing waiting times in primary care clinics in Cape Town, South Africa
    (2015) Daniels, Johann Alexander; Zweigenthal, Virginia; Reagon Gavin
    Objective: A waiting time survey (WTS), conducted in 2007 at 94% of clinics in Cape Town, measured length of patient waiting times (WT) for services and provided recommendations to shorten waiting times. Whether subsequent implementation of these recommendations occurred was unknown, hence a study was conducted to assess the impact of the previous waiting time survey recommendations on stimulating efforts to reduce waiting times and whether waiting times had reduced. Methods: A cross-sectional analytical study design assessed the perceptions of 92% of clinic managers in Cape Town, regarding the 2007 survey, while a before and after study design assessed changes in waiting time between 2007 and 2011, using a random sample of 22 clinics. Results: The overall median waiting time of all clinics in the sample decreased by 21 minutes in 2011 (95% CI 11.77-30.23), a 28% decrease from 2007. This reduction was manifest at individual clinic level as well, with 55% of clinics reducing their median waiting time by at least 15 minutes. No specific factors, including whether recommendations to reduce waiting times were implemented, were associated with decreases in waiting times. Implementation of recommendations to reduce waiting times was 2.67 times (95% CI 1.33-5.40) more likely amongst those who received written recommendations and 2.3 times ) 95% CI 1.28-4.19) more likely amongst managers with 5 or more years' experience. Conclusion: The decrease in waiting times in primary care urban clinics subsequent to a waiting time survey, demonstrates the utility of waiting times surveys, although no specific factors associated with the decrease in waiting time were identified.

    Comparing the accuracy of brief versus long depression screening instruments which have been validated in low and middle income countries: a systematic review
    (BioMed Central Ltd, 2012) Akena, Dickens; Joska, John; Obuku, Ekwaro; Amos, Taryn; Musisi, Seggane; Stein, Dan
    BACKGROUND: Given the high prevalence of depression in primary health care (PHC), the use of screening instruments has been recommended. Both brief and long depression screening instruments have been validated in low and middle income countries (LMIC), including within HIV care settings. However, it remains unknown whether the brief instruments validated in LMIC are as accurate as the long ones. METHODS: We conducted a search of PUBMED, the COCHRANE library, AIDSLINE, and PSYCH-Info from their inception up to July 2011, for studies that validated depression screening instruments in LMIC. Data were extracted into tables and analyzed using RevMan 5.0 and STATA 11.2 for the presence of heterogeneity. RESULTS: Nineteen studies met our inclusion criteria. The reported prevalence of depression in LMIC ranged from 11.1 to 53%. The area under curve (AUC) scores of the validated instruments ranged from 0.69-0.99. Brief as well as long screening instruments showed acceptable accuracy (AUC[greater than or equal to]0.7). Five of the 19 instruments were validated within HIV settings. There was statistically significant heterogeneity between the studies, and hence a meta-analysis could not be conducted to completion. Heterogeneity chi-squared = 189.23 (d.f. = 18) p<.001. CONCLUSION: Brief depression screening instruments in both general and HIV-PHC are as accurate as the long ones. Brief scales may have an edge over the longer instruments since they can be administered in a much shorter time. However, because the ultra brief scales do not include the whole spectrum of depression symptoms including suicide, their use should be followed by a detailed diagnostic interview.

    Critiquing the response to the Ebola epidemic through a Primary Health Care Approach
    (2016) Scott, Vera; Crawford-Browne, Sarah; Sanders, David
    Abstract Background The 2014/2015 West Africa Ebola epidemic has caused the global public health community to engage in difficult self-reflection. First, it must consider the part it played in relation to an important public health question: why did this epidemic take hold and spread in this unprecedented manner? Second, it must use the lessons learnt to answer the subsequent question: what can be done now to prevent further such outbreaks in the future? These questions remain relevant, even as scientists announce that the Guinea Phase III efficacy vaccine trial shows that rVSV-EBOV (Merck, Sharp & Dohme) is highly efficacious in individuals. This is a major breakthrough in the fight against Ebola virus disease (EVD). It does not replace but may be a powerful adjunct to current strategies of EVD management and control. Discussion We contribute to the current self-reflection by presenting an analysis using a Primary Health Care (PHC) approach. This approach is appropriate as African countries in the region affected by EVD have recommitted themselves to PHC as a framework for organising health systems and the delivery of health services. The approach suggests that, in an epidemic made complex by weak pre-existing health systems, lack of trust in authorities and mobile populations, a broader approach is required to engage affected communities. In the medium-term health system development with attention to primary level services and community-based programmes to address the major disease burden of malaria, diarrhoeal disease, meningitis, tuberculosis and malnutrition is needed. This requires the development of local management and an investment in human resources for health. Crucially this has to be developed ahead of, and not in parallel with, future outbreaks. In the longer-term a commitment is required to address the underlying social determinants which make these countries so vulnerable, and limit their capacity to respond effectively to, epidemics such as EVD. Conclusion The PHC approach offers an insightful critique of the global and regional factors which have compromised the response of health systems in Guinea, Liberia and Sierra Leone as well as suggesting what a strengthened EVD response might involve in the short, medium and long-term.

    Developing indicators for Monitoring and evaluation of the implementation of the Primary Health Care Approach in Health Sciences at the University of Cape Town using a DELPHI method
    (2021) Datay, Mohammed Ishaaq; Singh, Shajila; Irlam, James
    Background The University of Cape Town Faculty of Health Sciences (UCT FHS) adopted the Primary Health Care (PHC) approach as its lead theme for teaching, research, and clinical service in1994 Aim To develop indicators to monitor and evaluate the implementation of the PHC approach in Health Sciences Education . Method A Delphi study, conducted over two rounds, presented indicators of Social Accountability from the Training for Health Equity Network (THEnet), as well as indicators derived from the principles of the PHC approach in the UCT FHS, to a national multidisciplinary panel. An electronic questionnaire was used to score each indicator according to relevance, feasibility/measurability, and its application to undergraduate and postgraduate curricula. Qualitative feedback on the proposed indicators was also elicited. Results Round 1: Of the 59 Social Accountability indicators presented to the panel, the 20 highest ranked indicators were selected for Round 2. Qualitative feedback challenged the link between social accountability and PHC, resulting in an additional 19 PHC-specific indicators being presented in Round 2. Round 2: The indicators which scored >85% and made the final list were: PHC: Continuity of care (94%); Holistic understanding of health care (88%); Respecting human rights (88%); Providing accessible care to all (88%); and Promoting health through health education (88%). THEnet: Safety of learners (88%); Education reflects communities' needs (86%); Teaching embodies social accountability (86%); Teaching is appropriate to learners' needs (86%) Conclusion These PHC and THEnet indicators can be used to assess the implementation of PHC in Health Sciences Education. The specific indicators identified reflect priorities relevant to the local context. One limitation is that some key priority indicators did not make the final list.

    The development, initial implementation and support of a primary health care training programme in rational drug use
    (1998) Orrell, Catherine Jane; Folb, Peter I; Woods, David R
    The Rational Drug Use Training Project is a district-oriented programme designed to improve rational drug use among primary health care prescribers in the South African public sector. This thesis describes the development of the project and details the initial implementation study in 3 facilities in Region B of KwaZulu-Natal. This was a small before-after study, with no control. There were three components: 1. A series of easily collectable drug use indicators, adapted from those developed by WHO/INRUD. These allow primary health care staff to monitor their prescribing patterns in a district or facility. Ninety sets of prescribing indicators were collected as a baseline at 3 facilities in KwaZulu-Natal in December 1996, by the district trainers and the Rational Drug Use Training Project staff. The process was repeated in March 1997, after the training intervention, by the district trainers alone. 2. The intervention was a 2-day training workshop in rational drug use. This is problem-based and trained on-site in primary health facilities. Training was done by 8 district trainers from Region B who were taught to present the workshop by the Rational Drug Use Training Project staff. The workshop covers principles of prescribing, use of standard treatment guidelines, principles of clinic stock management and principles of good dispensing. Staff are encouraged to develop their self-learning skills through questioning, and seeking answers to clinical and drug related queries. 3. A set of resources, including texts, treatment guidelines and information centres, to provide quality, safe and unbiased drug information, are made accessible to staff at primary care level. These are available by post, telephone or e-mail. The Primary Care Medicines Resource Centre at the University of Durban-Westville was developed as a result of this study. Significant improvements in prescribing habits were noticed after the study. There was an increase in the percentage of drugs prescribed by their generic names (p=0.000); an increase in the number of medications adequately labelled (p=0.0132); a decrease in the cost of prescriptions (p=0.0134); and a decrease in the number of prescriptions that did not follow standard treatment guidelines at all for that diagnosis (p=0.0109). The Mann-Whitney U- test was used for statistical analysis. There were no significant changes in the average number of drugs per prescription; the percentage of drugs from the Essential Drugs List; and the number of prescriptions that completely followed standard treatment guidelines. Qualitative feedback was favourable too. This was a difficult study to undertake. The staff and funding organisation, Health Systems Trust, fell outside of the provincial health structure and met resistance at that level. Regional politics shaped the programme's design. District trainers needed for the cascade approach were not available. District staff remained entrenched in a traditional health hierarchy and found it difficult to function as a team. The will of district prescribing staff to learn was low. Rational drug use training is only one of a number of essential elements of in-service training urgently needed by these staff. Despite these problems, quantitative and qualitative success was shown. The Training Manual, developed in support of the training, has been in demand. The Primary Care Medicines Resource Centre is growing. Primary care prescribers have been motivated to monitor their own practices and manage their own clinic stock. The project is a successful example of multi-disciplinary and institutional collaboration. The Rational Drug Use Training Project has expanded to eight other health districts in 1997. A list of criteria, such as the need for a district trainer, have been set. These must be met by the district before training will commence. The project is a resource for Initiative for Sub-District Support, a joint district development programme of Health System Trust and the Department of Health. Most expansion in 1998 will be through this initiative. The difficulties encountered and achievements made during this small study will be used to support, and hopefully strengthen, the development of the primary health care oriented district health system, so urgently needed by the South African population.

    From ‘stepchild of primary healthcare’ to priority programme: Lessons for the implementation of the National Integrated School Health Policy in South Africa
    (2013) Shung-King, Maylene
    In this article, I explore the South African 2003 National School Health Policy (NSHP) and the revised 2012 Integrated School Health Policy (ISHP). I examine whether the shortcomings in the development, content and implementation of the 2003 NSHP, and the context in which it was implemented, have been addressed adequately in the 2012 ISHP. The shortcomings include poorly structured relationships among key policy actors; an absent policy translation process resulting in insufficient understanding and prioritisation of school health by district and facility managers; and poor support and training of nurses. Insufficient capacity and resources, compounded by inadequate referral service capacity, resulted in the inequitable coverage and quality of the service and caused nurses to refer to school health as 'the stepchild of primary healthcare'. The comparison of the 2003 and 2012 policies is guided by the policy analysis framework of the Walt and Gilson policy triangle, which considers the policy context, process of policy development, policy actors and the policy content as key dimensions to successful policy development and implementation. I draw on an evaluation of a six-year implementation period (2003 - 2009) of the 2003 NSHP, which revealed the implementation challenges with the related explanatory factors. I provide lessons from the evaluation of the 2003 NSHP, highlight the policy changes in the new 2012 ISHP and finally highlight key opportunities, and remaining challenges, for the implementation of the new 2012 ISHP.

    Health systems context(s) for integrating mental health into primary health care in six Emerald countries: a situation analysis
    (2017) Mugisha, James; Abdulmalik, Jibril; Hanlon, Charlotte; Petersen, Inge; Lund, Crick; Upadhaya, Nawaraj; Ahuja, Shalini; Shidhaye, Rahul; Mntambo, Ntokozo; Alem, Atalay; Gureje, Oye; Kigozi, Fred
    Abstract Background Mental, neurological and substance use disorders contribute to a significant proportion of the world’s disease burden, including in low and middle income countries (LMICs). In this study, we focused on the health systems required to support integration of mental health into primary health care (PHC) in Ethiopia, India, Nepal, Nigeria, South Africa and Uganda. Methods A checklist guided by the World Health Organization Assessment Instrument for Mental Health Systems (WHO-AIMS) was developed and was used for data collection in each of the six countries participating in the Emerging mental health systems in low and middle-income countries (Emerald) research consortium. The documents reviewed were from the following domains: mental health legislation, health policies/plans and relevant country health programs. Data were analyzed using thematic content analysis. Results Three of the study countries (Ethiopia, Nepal, Nigeria, and Uganda) were working towards developing mental health legislation. South Africa and India were ahead of other countries, having enacted recent Mental Health Care Act in 2004 and 2016, respectively. Among all the 6 study countries, only Nepal, Nigeria and South Africa had a standalone mental health policy. However, other countries had related health policies where mental health was mentioned. The lack of fully fledged policies is likely to limit opportunities for resource mobilization for the mental health sector and efforts to integrate mental health into PHC. Most countries were found to be allocating inadequate budgets from the health budget for mental health, with South Africa (5%) and Nepal (0.17%) were the countries with the highest and lowest proportions of health budgets spent on mental health, respectively. Other vital resources that support integration such as human resources and health facilities for mental health services were found to be in adequate in all the study countries. Monitoring and evaluation systems to support the integration of mental health into PHC in all the study countries were also inadequate. Conclusion Integration of mental health into PHC will require addressing the resource limitations that have been identified in this study. There is a need for up to date mental health legislation and policies to engender commitment in allocating resources to mental health services.

    Integrating mental health into primary health care in Zambia: a care provider's perspective
    (BioMed Central Ltd, 2010) Mwape, Lonia; Sikwese, Alice; Kapungwe, Augustus; Mwanza, Jason; Flisher, Alan; Lund, Crick; Cooper, Sara
    BACKGROUND:Despite the 1991 reforms of the health system in Zambia, mental health is still given low priority. This is evident from the fragmented manner in which mental health services are provided in the country and the limited budget allocations, with mental health services receiving 0.4% of the total health budget. Most of the mental health services provided are curative in nature and based in tertiary health institutions. At primary health care level, there is either absence of, or fragmented health services.AIMS:The aim of this paper was to explore health providers' views about mental health integration into primary health care. METHODS: A mixed methods, structured survey was conducted of 111 health service providers in primary health care centres, drawn from one urban setting (Lusaka) and one rural setting (Mumbwa). RESULTS: There is strong support for integrating mental health into primary health care from care providers, as a way of facilitating early detection and intervention for mental health problems. Participants believed that this would contribute to the reduction of stigma and the promotion of human rights for people with mental health problems. However, health providers felt they require basic training in order to enhance their knowledge and skills in providing health care to people with mental health problems.RECOMMENDATIONS:It is recommended that health care providers should be provided with basic training in mental health in order to enhance their knowledge and skills to enable them provide mental health care to patients seeking help at primary health care level. CONCLUSION: Integrating mental health services into primary health care is critical to improving and promoting the mental health of the population in Zambia.

    An interdisciplinary study exploring how health communication can most effectively explain Antiretroviral Medication (ART) and motivate adherence among young people
    (2016) Hickson, Warren; Mayers, Pat; Newing, Helen
    The aim of this study was to explore factors contributing to the success of health communication strategies and supporting visual communication tool(s) designed to explain antiretroviral medication (ART) adherence, and motivate young people who live with HIV to follow an adherence regime. The study drew from the social sciences, including psychology, health sciences and communication. Currently there are an estimated 6.8 million people living with HIV in South Africa, making it the site of the largest HIV epidemic in the world (UNAIDS, 2014). Antiretroviral Therapy (ART) is the only effective treatment for HIV and is one of the most demanding medicine regimes, requiring a 90% compliance. Various studies have documented worryingly poor levels of adherence to ART, especially amongst adolescents and young adults in South Africa. The empirical research consisted of a qualitative case study in Khayelitsha, a periurban township on the edge of Cape Town. It focused on young people from Khayelitsha and health care professionals - doctors, nurses, HIV counsellors and pharmacists. Using grounded theory data collection was carried out during two phases of fieldwork, interspersed with periods for data processing and analysis. The principal methods used were focus groups, semi-structured interviews and participant observation. Two key factors emerged from the data that form the basis of a new theoretical understanding: first, concerning how young people become motivated to learn about treatment and adhere to it, and second, concerning how information about treatment can best be communicated to them. In relation to the first of these, findings showed that young people were traumatised by an HIV diagnosis, fearing both that they would get sick and suffer an early death and also that they would be rejected by their belonging groups. This meant that they could not take in the factual information offered, and in addition, had no motivation to do so because the diagnosis resulted in a loss of hope for their present and future lives. According to young people, motivation was an outcome of re-connecting to one or more trusted significant other(s) from within their belonging group, who accepted and supported them. This in turn affirmed their prior belonging identities of son, daughter, cousin or close friend and then reconnected them to their present and future hopes. This renewed motivation to live was the basis for their becoming motivated to learn about treatment and adhere to it. In relation to the second factor, this study found that current communications about treatment were not effective. Specifically, the use of metaphors, which was seen among clinicians as a method of simplifying the complexity of ART adherence messages, was in fact creating confusion. Also, the use of printed information in isolation was not effective; communication was much more effective when it provided a space for discussion. These two key factors form the basis of a health communication strategy for young people who live with HIV and need to adhere to ART. Following on from these findings the study included the production of a film and animation that were identified as the visual communication media that would best support young people's understanding and motivation to adherence. The film presents a case study of a young person who overcame their initial diagnosis shock and, through the acceptance and support of his family, learned to live a normal life with HIV. Young people had said that they wanted to be able to view a film of this kind soon after their diagnosis. The animation, which was designed using a participatory process, used 'iso-type' as the central visual language. It was piloted, and this showed that the best use of a visual communication tool was in a setting that allowed young people to talk about prior losses to HIV within their families and community and about their confusion about treatment, and to ask questions about the meaning of complex biomedical concepts such as an undetectable viral load. All young people who visited the clinics, irrespective of test results, said that they wanted to learn about ART so that they could support friends and family members who lived with HIV, change perceptions about HIV among peers and better prepare in the case of becoming HIV positive themselves. Therefore it is recommended that communication strategies should target patients, their belonging groups and the wider community. This substantive theory contributes knowledge relevant to how ART adherence is communicated to young people. More broadly, this thesis argues that an interdisciplinary approach is required if communication practitioners are to properly understand the meaning that a population attributes to a health challenge; especially in the context of motivation and understanding. It is only when those meanings are fully identified through consolidated social science research that a communication strategy and supporting visual tools can be successfully designed.

    Primary care clinical practice guidelines in South Africa: qualitative study exploring perspectives of national stakeholders
    (2017) Kredo, Tamara; Abrams, Amber; Young, Taryn; Louw, Quinette; Volmink, Jimmy; Daniels, Karen
    BACKGROUND: Clinical practice guidelines (CPGs) are common tools in policy and clinical practice informing clinical decisions at the bedside, governance of health facilities, health insurer and government spending, and patient choices. South Africa's health sector is transitioning to a national health insurance system, aiming to build on other primary health care initiatives to transform the previously segregated, inequitable services. Within these plans CPGs are an integral tool for delivering standardised and cost effective care. Currently, there is no accepted standard approach to developing, adapting or implementing CPGs efficiently or effectively in South Africa. We explored the current players; drivers; and the context and processes of primary care CPG development from the perspective of stakeholders operating at national level. METHODS: We used a qualitative approach. Sampling was initially purposeful, followed by snowballing and further sampling to reach representivity of primary care service providers. Individual in-depth interviews were recorded and transcribed verbatim. We used thematic content analysis to analyse the data. RESULTS: We conducted 37 in-depth interviews from June 2014-July 2015. We found CPG development and implementation were hampered by lack of human and funding resources for technical and methodological work; fragmentation between groups, and between national and provincial health sectors; and lack of agreed systems for CPG development and implementation. Some CPG contributors steadfastly work to improve processes aiming to enhance communication, use of evidence, and transparency to ensure credible guidance is produced. Many interviewed had shared values, and were driven to address inequity, however, resource gaps were perceived to create an enabling environment for commercial interests or personal agendas to drive the CPG development process. CONCLUSIONS: Our findings identified strengths and gaps in CPG development processes, and a need for national standards to guide CPG development and implementation. Based on our findings and suggestions from participants, a possible way forward would be for South Africa to have a centrally coordinated CPG unit to address these needs and aspects of fragmentation by devising processes that support collaboration, transparency and credibility across sectors and disciplines. Such an initiative will require adequate resourcing to build capacity and ensure support for the delivery of high quality CPGs for South African primary care.

    Reasons why patients with primary health care problems access a secondary hospital emergency centre
    (2012) Becker, Juanita; Dell, Angela; Jenkins, Louis; Sayed, Rauf
    BACKGROUND: Many patients present to an emergency centre (EC) with problems that could be managed at primary healthcare (PHC) level. This has been noted at George Provincial Hospital in the Western Cape province of South Africa. AIM: In order to improve service delivery, we aimed to determine the patient-specific reasons for accessing the hospital EC with PHC problems. METHODS: A descriptive study using a validated questionnaire to determine reasons for accessing the EC was conducted among 277 patients who were triaged as green (routine care), using the South African Triage Score. The duration of the complaint, referral source and appropriateness of referral were recorded. RESULTS: Of the cases 88.2% were self-referred and 30.2% had complaints persisting for more than a month. Only 4.7% of self-referred green cases were appropriate for the EC. The three most common reasons for attending the EC were that the clinic medicine was not helping (27.5%), a perception that the treatment at the hospital is superior (23.7%), and that there was no PHC service after-hours (22%). CONCLUSIONS: Increased acceptability of the PHC services is needed. The current triage system must be adapted to allow channelling of PHC patients to the appropriate level of care. Strict referral guidelines are needed.

    Schools of public health in low and middle-income countries: an imperative investment for improving the health of populations?
    (2016) Rabbani, Fauziah; Shipton, Leah; White, Franklin; Nuwayhid, Iman; London, Leslie; Ghaffar, Abdul; Ha, Bui Thi Thu; Tomson, Göran; Rimal, Rajiv; Islam, Anwar; Takian, Amirhossein; Wong, Samuel; Zaidi, Shehla; Khan, Kausar; Karmaliani, Rozina; Abbasi, Imran Naeem; Abbas, Farhat
    Abstract Background Public health has multicultural origins. By the close of the nineteenth century, Schools of Public Health (SPHs) began to emerge in western countries in response to major contemporary public health challenges. The Flexner Report (1910) emphasized the centrality of preventive medicine, sanitation, and public health measures in health professional education. The Alma Ata Declaration on Primary Health Care (PHC) in 1978 was a critical milestone, especially for low and middle-income countries (LMICs), conceptualizing a close working relationship between PHC and public health measures. The Commission on Social Determinants of Health (2005–2008) strengthened the case for SPHs in LMICs as key stakeholders in efforts to reduce global health inequities. This scoping review groups text into public health challenges faced by LMICs and the role of SPHs in addressing these challenges. Main text The challenges faced by LMICs include rapid urbanization, environmental degradation, unfair terms of global trade, limited capacity for equitable growth, mass displacements associated with conflicts and natural disasters, and universal health coverage. Poor governance and externally imposed donor policies and agendas, further strain the fragile health systems of LMICs faced with epidemiological transition. Moreover barriers to education and research imposed by limited resources, political and economic instability, and unbalanced partnerships additionally aggravate the crisis. To address these contextual challenges effectively, SPHs are offering broad based health professional education, conducting multidisciplinary population based research and fostering collaborative partnerships. SPHs are also looked upon as the key drivers to achieve sustainable development goals (SDGs). Conclusion SPHs in LMICs can contribute to overcoming several public health challenges being faced by LMICs, including achieving SDGs. Most importantly they can develop cadres of competent and well-motivated public health professionals: educators, practitioners and researchers who ask questions that address fundamental health determinants, seek solutions as agents of change within their mandates, provide specific services and serve as advocates for multilevel partnerships. Funding support, human resources, and agency are unfortunately often limited or curtailed in LMICs, and this requires constructive collaboration between LMICs and counterpart institutions from high income countries.

    The impact of HIV status and antiretroviral treatment on TB treatment outcomes of new tuberculosis patients attending co-located TB and ART services in South Africa: a retrospective cohort study
    (2015) Nglazi, Mweete D; Bekker, Linda‐Gail; Wood, Robin; Kaplan, Richard
    BackgroundThe implementation of collaborative TB-HIV services is challenging. We, therefore, assessed TB treatment outcomes in relation to HIV infection and antiretroviral therapy (ART) among TB patients attending a primary care service with co-located ART and TB clinics in Cape Town, South Africa.MethodsIn this retrospective cohort study, all new TB patients aged ≥ 15years who registered and initiated TB treatment between 1 October 2009 and 30 June 2011 were identified from an electronic database. The effects of HIV-infection and ART on TB treatment outcomes were analysed using a multinomial logistic regression model, in which treatment success was the reference outcome.ResultsThe 797 new TB patients included in the analysis were categorized as follows: HIV- negative, in 325 patients (40.8%); HIV-positive on ART, in 339 patients (42.5%) and HIV-positive not on ART, in 133 patients (16.7%). Overall, bivariate analyses showed no significant difference in death and default rates between HIV-positive TB patients on ART and HIV-negative patients. Statistically significant higher mortality rates were found among HIV-positive patients not on ART compared to HIV-negative patients (unadjusted odds ratio (OR) 3.25; 95% confidence interval (CI) 1.53–6.91). When multivariate analyses were conducted, the only significant difference between the patient categories on TB treatment outcomes was that HIV-positive TB patients not on ART had significantly higher mortality rates than HIV-negative patients (adjusted OR 4.12; 95% CI 1.76–9.66). Among HIV-positive TB patients (n = 472), 28.2% deemed eligible did not initiate ART in spite of the co-location of TB and ART services. When multivariate analyses were restricted to HIV-positive patients in the cohort, we found that being HIV-positive not on ART was associated with higher mortality (adjusted OR 7.12; 95% CI 2.95–18.47) and higher default rates (adjusted OR 2.27; 95% CI 1.15–4.47).ConclusionsThere was no significant difference in death and default rates between HIV-positive TB patients on ART and HIV negative TB patients. Despite the co-location of services 28.2% of 472 HIV-positive TB patients deemed eligible did not initiate ART. These patients had a significantly higher death and default rates.

    The targeting of nutritionally at-risk children attending a primary health care facility in the Western Cape Province of South Africa
    (2006) Schoeman, SE; Hendricks, MK; Hattingh, SP; Benadé, AJS; Laubscher, JA; Dhansay, M A
    AIM: The aim of this study was to determine the practices of primary health care (PHC) nurses in targeting nutritionally at-risk infants and children for intervention at a PHC facility in a peri-urban area of the Western Cape Province of South Africa. METHODOLOGY: Nutritional risk status of infants and children <6 years of age was based on criteria specified in standardised nutrition case management guidelines developed for PHC facilities in the province. Children were identified as being nutritionally at-risk if their weight was below the 3rd centile, their birth weight was less than 2500 g, and their growth curve showed flattening or dropping off for at least two consecutive monthly visits. The study assessed the practices of nurses in identifying children who were nutritionally at-risk and the entry of these children into the food supplementation programme (formerly the Protein-Energy Malnutrition Scheme) of the health facility. Structured interviews were conducted with nurses to determine their knowledge of the case management guidelines; interviews were also conducted with caregivers to determine their sociodemographic status. RESULTS: One hundred and thirty-four children were enrolled in the study. The mean age of their caregivers was 29.5 (standard deviation 7.5) years and only 47 (38%) were married. Of the caregivers, 77% were unemployed, 46% had poor household food security and 40% were financially dependent on non-family members. Significantly more children were nutritionally at-risk if the caregiver was unemployed (54%) compared with employed (32%) (P=0.04) and when there was household food insecurity (63%) compared with household food security (37%) (P<0.004). Significantly more children were found not to be nutritionally at-risk if the caregiver was financially self-supporting or supported by their partners (61%) compared with those who were financially dependent on non-family members (35%) (P=0.003). The weight results of the nurses and the researcher differed significantly (P<0.001), which was largely due to the different scales used and weighing methods. The researcher's weight measurements were consistently higher than the nurses' (P<0.00). The researcher identified 67 (50%) infants and children as being nutritionally at-risk compared with 14 (10%) by the nurses. The nurses' poor detection and targeting of nutritionally at-risk children were largely a result of failure to plot weights on the weight-for-age chart (55%) and poor utilisation of the Road to Health Chart. CONCLUSIONS: Problems identified in the practices of PHC nurses must be addressed in targeting children at nutritional risk so that appropriate intervention and support can be provided. More attention must be given to socio-economic criteria in identifying children who are nutritionally at-risk to ensure their access to adequate social security networks.

    Understanding Primary Health Care
    (2016-01-07) Mitchell, Veronica
    This resource could be useful to all Health Science students and educators who seek to learn or teach the basics of Primary Health Care (PHC). It aims to promote an understanding of the complex components of PHC. A baobab tree visually represents the PHC elements, principles, referral system and components of Comprehensive PHC. Links to a wide range of online examples, mostly as short YouTube videos, provide explanations for the terms and concepts.
