Improving public health sector service delivery in the Free State, South Africa: development of a provincial intervention model.

BACKGROUND: Public health sector service delivery challenges leading to poor population health outcomes have been observed in the Free State province of South Africa for the past decade. A multi-method situation appraisal of the different functional domains revealed serious health system deficiencies and operational defects, notably fragmentation of healthcare programmes and frontline services, as well as challenges related to governance, accountability and human resources for health. It was therefore necessary to develop a system-wide intervention to comprehensively address defects in the operation of the public health system and its major components. METHODS: This study describes the development of the 'Health Systems Governance & Accountability' (HSGA) intervention model by the Free State Department of Health (FSDoH) in collaboration with the community and other stakeholders following a participatory action approach. Documented information collected during routine management processes were reviewed for this paper. Starting in March 2013, the development of the HSGA intervention model and the concomitant application of Kaplan and Norton's (1992) Balanced Scorecard performance measurement tool was informed by the World Health Organization's (2007) conceptual framework for health system strengthening and reform comprised of six health system 'building blocks.' The multiple and overlapping processes and actions to develop the intervention are described according to the four steps in Kaplan et al.'s (2013) systems approach to health systems strengthening: (i) problem identification, (ii) description, (iii) alteration and (iv) implementation. RESULTS: The finalisation of the HSGA intervention model before end-2013 was a prelude to the development of the FSDoH's Strategic Transformation Plan 2015-2030. The HSGA intervention model was used as a tool to implement and integrate the Plan's programmes moving forward with a consistent focus on the six building blocks for health systems strengthening and the all-important linkages between them. CONCLUSION: The model was developed to address fragmentation and improve public health service delivery by the provincial health department. In January 2016, the intervention model became an official departmental policy, meaning that it was approved for implementation, compliance, monitoring and reporting, and became the guiding framework for health systems strengthening and transform in the Free State.

HIV-prevention measures on a university campus in South Africa - perceptions, practices and needs of undergraduate medical students.

Background: Young adults such as university students are considered to be a key population for HIV-prevention efforts. This study aimed to determine the perceptions, practices and needs of undergraduate medical students regarding HIV-prevention measures available on campus. Methods: The research design was descriptive cross-sectional. Data were collected using an anonymous, self-administered questionnaire distributed to all 745 undergraduate medical students in the School of Clinical Medicine, University of the Free State, South Africa, of whom 470 responded (63.1%). Results: Almost half (45.5%) of all respondents across the five academic years had received information about available HIV-prevention measures on campus. Most reported that information had been received during lectures (59.7%) and only 24.2% from the local health clinic on campus. The findings also revealed that 14.2% of students had used at least one prevention measure in the past, while the majority of students (70.2%) used abstinence as an HIV-prevention measure. A large percentage of all the students (47.6%) had been tested for HIV before the start of the study. Two-thirds (67%) of students indicated that the current HIV-prevention services on campus were not sufficient. Conclusion: Medical students received HIV-prevention information as part of their curriculum but this was deemed not to be sufficient. This study suggests that tertiary education institutions should evaluate the effectiveness of strategies currently in place for the distribution and awareness of HIV-prevention measures and sexual health issues affecting students, using a student-centred approach.

Hepatitis B immunisation and immune status of nurses in a regional hospital in central South Africa.

BACKGROUND:  The hepatitis B virus (HBV) is one of the most important biological occupational hazards for healthcare workers. A high percentage of HBV infections are attributable to percutaneous occupational exposure. This study aimed to describe the HBV immunisation and current immune status of all the nurses employed in a regional hospital in central South Africa. METHODS:  A descriptive record review included all the nurses (N = 388) employed in a regional hospital in central South Africa from 01 January 2018 to 31 January 2020. A total of 289 health records were included in the study. Data were analysed using descriptive statistics. Logistic regression analysis was used to establish factors associated with full immunisation. RESULTS:  Most nurses were females (87.9%), working in medical (27.0%) wards. Only 20.4% of nurses received one dose of vaccine, while 51.2% received the three prescribed doses. However, 91.2% of nurses did not receive the vaccine at the correct intervals. Most of the tested nurses (71.0%) were immune. Immunisation status was significantly associated with religion (p  0.001) and schedule (p = 0.003). Nurses who were non-Christians were 35.9% less likely to be fully vaccinated compared to Christians. CONCLUSION:  Half of the nursing staff received three doses as prescribed. All nurses should receive the vaccine against HBV and their immune status monitored to minimise the risk of an infection. It is therefore recommended that proof of immunity should be a requirement.Contribution: This study found a high percentage of nurses with HBV antibodies, which will ensure workplace safety.

Chronic diseases of lifestyle curriculum: Students' perceptions in primary health care settings.

BACKGROUND: Community-based primary health care (PHC) forms the foundation of healthcare in South Africa. Medical programmes need to equip future health practitioners to face the challenges of the rising burden of chronic diseases of lifestyle (CDL) in different communities. Community-based education (CBE) contributes to developing knowledge, skills and attitudes appropriate to the challenges experienced in the PHC context. AIM: To explore medical students' perceptions of the current CDL curriculum and related programmes during CBE rotations. SETTING: The study was conducted among fourth- and fifth-year medical students at the University of the Free State, South Africa. METHODS: Focus group discussions were conducted and data were analysed thematically. RESULTS: Themes included perceptions of the CDL curriculum, relevance thereof for the PHC setting and barriers and challenges to implementing PHC programmes. This study identified foundational CDL content that needs to be incorporated or revisited at strategic points. Participants identified the need to contextualise educational programmes and focus on affordable, culturally acceptable and holistic healthcare prevention strategies. Barriers and challenges included high patient load, resource constraints, the lack of continuous care and focus on communicable diseases. Community-based education rotations were described as meaningful opportunities to develop professional attributes, competencies and skills. CONCLUSION: This study identified foundational concepts to consider at key points throughout the curriculum. Incorporating creative and reflective learning activities in CDL modules can prepare students for the realities of PHC settings.Contribution: This study provides insight into medical students' perceptions of the CDL curriculum and informs future curriculum content for CDL modules.

What social determinants will cause ethical challenges in geriatric care? Comments from South Africa.

Background: Social determinants are defined as those nonmedical factors that influence health. Their influence is especially evident in vulnerable communities, such as the geriatric one. However, which social determinants will cause ethical challenges in geriatric healthcare in South Africa are not yet confirmed. Objective: This study first identified which social determinants influence geriatric care. The study then established which of these social determinants raises ethical challenges in geriatric care. Methods: Twenty statements were identified from the literature review and were grouped into 3 indexes, focusing respectively on i) a general view on public health and social determinants; ii) social determinants influencing geriatric people's health; iii) the consequences of social determinants on geriatric people's health. The rating was based on presenting the statements employing a 5- point Likert scale. Results: The rating of statements confirmed the generally accepted view that social determinants impact geriatric people's health. The responses to the statements were an additional confirmation that the quality and access to healthcare services influence geriatric care and lead to ethical challenges. Matters such as corruption, limited resources, and the COVID-19 pandemic contribute to the influence of social determinants and the expected but failed ethical behavior toward the geriatric community. Conclusion: The geriatric community is vulnerable because of the ongoing social factors that have a negative impact on health, of which healthcare quality and provision are significant contributing factors. These factors contribute to ethical challenges in healthcare for the geriatric community.

Health managers and community representatives' views of a system-wide intervention to strengthen public healthcare in the Free State, South Africa.

Background: A system-wide health system strengthening (HSS) initiative, the Health Systems Governance and Accountability (HSGA) intervention, was developed, translated to policy, and implemented in the Free State province. This study assessed health managers (HMs) and community representatives' (CRs) views of the intervention and whether it improved integration and performance. Method: A questionnaire survey among 147 HMs and 78 CRs and 14 focus group discussions (FGDs) with a mean of 10.3 participants and a total of 102 HMs and 42 CRs, were conducted. The questionnaire and FGD data were descriptively and thematically analysed to triangulate findings. Results: Many HMs (44%) mostly positioned at the operational levels indicated that implementation of the HSGA intervention did contribute to integration of health services. Most CRs (54%) believed that communities were actively involved in the intervention. However, both the self-administered questionnaire and the FGD data evidenced lack of policy awareness among, especially, operational-level HMs. Conclusion: From the perspectives of HMs and CRs, the implementation of the intervention was viewed as a step forward in strengthening public healthcare to respond to system deficiencies in the Free State province. Earlier engagement of especially operational-level HMs during reforms may be beneficial in successfully implementing HSS interventions.

Implementing an intervention to improve leadership/management of public healthcare services in the Free State Province, South Africa: lessons learned.

Background: Based on the World Health Organization's health systems strengthening framework, the Health Systems Governance and Accountability (HSGA) intervention to strengthen public health leadership/management, service integration and outcomes was developed in the Free State. Objectives: This study describes the process to implement and measure the effects of the HSGA intervention for system-wide improvement of leadership/management under routine conditions in a resource-constrained setting. Methods: Based on normalisation process theory, participatory discussions were held with health managers, staff and local stakeholders to attain buy-in. Evaluation of the implementation process considered progress in improving leadership/management through application of the Balanced Scorecard (BSC). All provincial reporting units were assessed during 2014/15 and again during 2015/16. Results: The mean scores on three BSC perspectives improved statistically significantly from 2014/15 to 2015/16: customer (p=0.0085), internal business processes (p=0.0008) and finance (p=0.0001). Overall leadership/management also improved significantly (p=0.0007). Conclusion: Improvement in leadership/management resulting from implementation of the HSGA intervention was observed during the two years under study. From this experience, successful implementation of a health systems strengthening intervention hinges on a participatory design, appropriate use of theory, as well as application of an evaluation approach to assess the success of implementation.

Obesity and sickness absenteeism among health workers in a private hospital in South Africa.

BACKGROUND: There is a worldwide trend among the general population including health workers to become more overweight and obese. Such obesity can reduce work ability as manifested through sickness absenteeism. The aim of this study was to describe the obesity among health workers in a private hospital in central South Africa, as measured by the body mass index (BMI) as well as the association of obesity and sickness absenteeism. METHODS: A cohort analytical study was conducted to describe changes in the BMI of employed health workers as well as the association of obesity and absenteeism in a private hospital in South Africa. The BMI measurement on employment, a repeat BMI at the time of the study as well as the sick leave days taken since employment of all health workers who had been employed for more than one year were analysed. RESULTS: Full time employees (n = 344) participated in the study of whom 33.7% were obese; 26.2% were overweight; 36.3% had normal weight and 3.7% were underweight at employment. On repeat BMI done in February 2016, 43.0% were obese; 27.6% were overweight; 28.2% had normal weight and 1.2% were underweight. There was no difference in the amount of sick leaves taken between the normal weight, overweight and obese groups. CONCLUSION: A trend among health workers to change to a higher BMI category during employment is concerning, but there was no statistically significant association between the different weight groups and sickness absenteeism. The negative impact of obesity on the productivity of workers cannot be ignored.

Building blocks for a public health ethics framework for the geriatric community.

BACKGROUND: The elderly population is steadily growing in South Africa. However, there is limited strategic planning or policy initiatives to address this group's vulnerability resulting in several public health ethical issues that need to be considered and addressed. This article aims to develop a public health ethics framework for the geriatric community with the purpose to review ethical implications when working with the geriatric community. METHODS: The Q-methodology was selected for data collection. Fifteen statements were ranked by means of a five-point Likert-scale questionnaire. Twenty-two participants from six geriatric institutions participated in the ranking of the statements. RESULTS: The ranking of the statements confirmed the need for a public health ethics framework to provide guidance when working with the geriatric community and to evaluate decisions about geriatric care. Such a framework should be application-based and practice-oriented which can assist in addressing unfamiliarity with public health ethics in general and can extend the capacity for decision-making. The ranking of these statements contributed to the scope of the planned framework, by considering the vulnerability of healthcare practitioners (as community of practitioners) and the geriatric community as a basis from which to promote justice in public health programmes. CONCLUSION: Based on the ranking of statements, eight building blocks for a public health ethics framework were identified. The building blocks are imbedded in professional ethics and care ethics. The proposed framework can give rise to social justice in public health and the ability to evaluate what the ethical implications are for public health policies, programmes and interventions aimed at the geriatric community.

What is public health ethics for the geriatric community?

Background: A growing ageing community puts additional demands on the public health system. This will contribute to ethical consequences for the health care sector. A public health ethics framework can contribute towards addressing the ethical challenges faced by the geriatric community. Aim: This article intends to contribute to a public health ethics framework for the geriatric community from a South African perspective. Setting: Twenty-two participants from six geriatric institutions, two each in the three provinces, participated in the research. The provinces are the Free State, Northern Cape and North West. Methods: Fifteen statements were rated using a five-point Likert scale questionnaire. The statements were grouped into three indexes, namely what is ethics, what is public health ethics and what is public health ethics for the geriatric community? Results: Ethical behaviour is observable not only from person to person but also through systems, processes and practices. The need is to understand how to apply ethical principles to the working environment. A public health ethic can be understood from applied, professional and social ethics. Conclusion: Public health ethics is the application of health care principles through a professional ethic resulting in care and relationship-building. The core of what public health is should be the basis to identify a public health ethic where the focus is on the community and improvement of the quality of health and well-being of the community. Contribution: No evidence of a public health ethics framework for the geriatric community could be identified in South Africa.

Magmatic karst reveals dynamics of crystallization and differentiation in basaltic magma chambers.

An understanding of magma chamber dynamics relies on answering three important yet highly controversial questions: where, why, and how magma chambers crystallize and differentiate. Here we report on a new natural phenomenon-the undercut-embayed chamber floor in the Bushveld Complex-which allows us to address these questions. The undercut-embayed floor is produced by magmatic karstification (i.e. erosion by dissolution) of the underlying cumulates by replenishing magmas that form basal flows on the chamber floor. This results in a few metres thick three-dimensional framework of spatially interconnected erosional remnants that separate the floor cumulates from the overlying resident melt. The basal flow in this environment is effectively cooled through the floor, inducing heterogeneous nucleation and in situ growth against much of its three-dimensional framework. The solidification front thus propagates in multiple directions from the surfaces of erosional remnants. Fractional crystallization may occur within this environment by convective removal of a compositional boundary layer from in situ growing crystals and is remarkably efficient even in very confined spaces. We propose that the way magma crystallizes and differentiates in the undercut-embayed chamber floor is likely common for the evolution of many basaltic magma chambers.

Fossilized solidifications fronts in the Bushveld Complex argues for liquid-dominated magmatic systems.

Chemical differentiation of magma on Earth occurs through physical separation of liquids and crystals. The mechanisms of this separation still remain elusive due to the lack of information on solidification fronts in plutonic magmatic systems. Here, we present records of fossilized solidification fronts from massive magnetitites of the Bushveld Complex in South Africa, obtained by two-dimensional geochemical mapping on field outcrops. The chemical zoning patterns of solidification fronts indicate that nucleation and crystallization occur directly at the chamber floor and result in near-perfect fractionation due to convective removal of a compositional boundary layer from in situ growing crystals. Our data precludes the existence of thick crystal mushes during the formation of massive magnetitites, thus providing no support for the recent paradigm that envisages only crystal-rich and liquid-poor mushy reservoirs in the Earth's crust.

Monomineralic anorthosites in layered intrusions are indicators of the magma chamber replenishment by plagioclase-only-saturated melts.

The formation of some Earth's monomineralic igneous rocks appears to be prohibited by constraints imposed by liquidus phase-equilibria on evolution of mantle-derived magmas. Yet, these rocks exist as stratiform layers in many mafic-ultramafic intrusions. One conspicuous example is monomineralic anorthosites in the Bushveld Complex that occur as stratiform layers up to hundreds of kilometres in length. Such monomineralic anorthosites appear to require parental melts saturated in plagioclase only but where and how to produce these melts remains a contentious issue. Here we argue that they are likely sourced from deep-seated magma reservoirs. In response to pressure reduction, these ascending melts become first superheated and then saturated in plagioclase after stalling and cooling in shallow-level chambers. Adcumulus growth of plagioclase from such melts at the chamber floor results in the formation of monomineralic anorthosites. We propose that stratiform layers of monomineralic anorthosites in layered intrusions are products of the chamber replenishment by melts whose saturation in plagioclase as a single liquidus phase is triggered by their transcrustal ascent towards the Earth's surface.

A Comparison of the Socio-Behavioral-Metabolic Risk Profiles and Associated Factors for Chronic Diseases of Lifestyle in Urban and Rural Communities in Central South Africa.

Background: The global escalating prevalence of lifestyle-related non-communicable diseases places a significant burden on health systems. Chronic diseases of lifestyle (CDL) are a group of diseases that share similar modifiable risk factors that can result in long-term disease processes. Considering the socio-behavioral-metabolic risk profiles of communities and risk factors predictive of the presence of CDL can assist in the development of focused and effective community-based prevention, intervention, and treatment programs for CDL. Aim: To determine the socio-behavioral-metabolic risk profiles and identify associated factors for the following CDL: obesity, cardiovascular disease, hypertension, and type 2 diabetes mellitus in rural and urban communities in central South Africa. Methodology: This cross-sectional study included adults aged 25-65 years in the rural Southern Free State and urban Mangaung. Social determinants, behavioral and metabolic risk factors, and inflammatory biomarkers for CDL were determined. Results: In total, 575 rural (mean age: 42 years; 71% female) and 429 urban (mean age: 44 years; 76% female) participants were included in the study. More than 20% of participants in both communities reported being previously diagnosed with cardiovascular diseases; with reported hypertension and diabetes mellitus more prevalent among rural participants. Insufficient intake of fruit and vegetables, alcohol use, and high blood pressure were among the top five risk factors in both communities. Physical inactivity ranked among the top two risk factors in the urban community; while alcohol and tobacco use was significantly higher in the rural community. Fibrinogen was the most prevalent inflammatory marker in both communities (32.9 rural vs. 48.3% urban). High sensitivity C-reactive protein (Hs-CRP), only available for rural participants, was high with increased levels in more than 80% of participants. In both communities, being female, having high blood pressure and increased fibrinogen levels were associated with obesity. Conclusion: This study illustrated the high prevalence of socio-behavioral-metabolic risk factors for CDL, and identified similarities and distinct differences in the risk profiles of rural and urban communities. Considering the CDL risk profiles of communities can assist in prioritizing health needs and contribute to the development of tailor-made community-based primary health care prevention, intervention, and health promotion programs.

Building capacity to secure healthier and safer working conditions for healthcare workers: A South African-Canadian collaboration.

Healthcare workers face difficult working conditions, particularly where HIV and tuberculosis add to understaffing. Questionnaires, workplace assessments, and discussion groups were conducted at a regional hospital in South Africa to obtain baseline data and input from the workforce in designing interventions. Findings highlighted weaknesses in knowledge, for example regarding the use of N95 respirators and safe handling of sharps, and suggested the need for improved training. Access to supplies and personal protective equipment was the major reported reason for failure to follow proper procedures; this was confirmed by workplace assessments. Discussion groups highlighted the important role for worker Health and Safety Committees (HSC), including in combating stigma and encouraging reporting. Interest in data to support decision-making resulted in development of the Occupational Health and Safety Information System (OHASIS); further training of HSCs is still needed. Multi-stakeholder international collaboration aimed at building HSC capacity is well-received.
