Determinants of mortality status and population attributable risk fractions of the North West Province, South African site of the international PURE study

BackgroundMortality data and comparative risk assessments from sub-Saharan Africa are limited. There is an urgent need for high quality population health surveys to be conducted, to improve the national health surveillance system. Our aim was to perform a comparative risk assesment and report on the mortality status and cause of death data of participants from a South African site of the international Prospective Urban Rural Epidemiology study.Methods1 921 Black participants were included, with a median observational time of 13 years resulting in 21 525 person-years. We performed a comparative risk assessment considering four health status domains: locality (rural vs. urban), socio-economic status (SES) (education and employment), lifestyle factors (physical activity, smoking and alcohol consumption) and prevalent diseases (human immunodeficiency virus (HIV), type 2 diabetes mellitus and hypertension). Next, population-attributable fractions (PAFs) were calculated to determine the mortality risk attributable to modifiable determinants.Results577 all-cause deaths occurred. Infectious diseases (28.1% of all deaths) were the most frequent cause of death, followed by cardiovascular disease (CVD) (22.4%), respiratory diseases (11.6%) and cancer (11.1%). The three main contributors to all-cause mortality were HIV infection, high SES and being underweight. HIV infection and underweight were the main contributors to infectious disease mortality and hypertension, the urban environment, and physical inactivity to CVD mortality. HIV had the highest PAF, followed by physical inactivity, alcohol and tobacco use and hypertension (for CVD mortality).ConclusionThis African population suffers from a quadruple burden of disease. Urban locality, high SES, prevalent disease (HIV and hypertension) and lifestyle factors (physical inactivity, tobacco and alcohol use) all contributed in varying degrees to all-cause and cause-specific mortalities. Our data confirm the public health importance of addressing HIV and hypertension, but also highlights the importance of physical inactivity, tobacco use and alcohol consumption as focal points for public health strategies to produce the most efficient mortality reduction outcomes.

Programmatic Approach to Hearing Health in Low- and Middle-Income Countries

Programmatic Approach to Hearing Health in Low- and Middle-Income Countries

Multimorbidity Patterns in a National HIV Survey of South African Youth and Adults.

IntroductionInformation pertaining to multimorbidity is frequently informed by studies from high income countries and it is unclear how these findings relate to low and middle income countries, where the burden of infectious disease is high. South Africa has a quadruple burden of disease which includes a high HIV prevalence and a growing burden of non-communicable diseases. This study aimed to analyse the prevalence and patterns (disease classes or clusters) of multimorbidity in South Africa.MethodsA secondary analysis of individuals over the age of 15 years who participated in the Fifth South African National HIV Prevalence, Incidence, Behavior and Communication Survey, 2017 (SABSSM 2017) was done. Six disease conditions were identified in the analysis (cancer, diabetes, heart disease, hypertension/high blood pressure, tuberculosis, and HIV). Chi-square tests were used to test for the differences in disease prevalence by sex. Common disease patterns were identified using a latent class analysis.ResultsThe sample included 27,896 participants, of which 1,837 had comorbidity or multimorbidity. When taking population-weighting into account, multimorbidity was present in 5.9% (95% CI: 5.4–6.4) of the population The prevalence of multimorbidity tended to be higher among females and increased with age, reaching 21.9% in the oldest age group (70+). The analyses identified seven distinct disease classes in the population. The largest class was “Diabetes and Hypertension” (36.3%), followed by “HIV and Hypertension” (31.0%), and “Heart disease and Hypertension” (14.5%). The four smaller classes were: “HIV, Diabetes, and Heart disease” (6.9%), “TB and HIV” (6.3%), “Hypertension, TB, and Cancer” (2.8%), and “All diseases except HIV” (2.2%).ConclusionAs the South African population continues to age, the prevalence of multimorbidity is likely to increase which will further impact the health care system. The prevalence of multimorbidity in the population was relatively low but reached up to 20% in the oldest age groups. The largest disease cluster was the combination of diabetes and hypertension; followed by HIV and hypertension. The gains in improving adherence to antiretrovirals amongst treatment-experienced people living with HIV, should be expanded to include compliance with lifestyle/behavioral modifications to blood pressure and glucose control, as well as adherence to anti-hypertension and anti-diabetic medication. There is an urgent need to improve the early diagnosis and treatment of disease in the South African population.

Laboratory parameters associated with prolonged hospital length of stay in COVID-19 patients in Johannesburg, South Africa

Background. Coronavirus disease (COVID-19) has imposed unprecedented stressors on South Africa (SA)’s healthcare system. Superimposed on the country’s quadruple burden of disease, pandemic-related care further exposes existing inequities. Some of these inequities are specific to hospital-based inpatient services, such as the geographical maldistribution of hospital beds, lack of oxygen supplies and assisted ventilation, and scarcity of trained healthcare workers. Certain high-risk groups, such as individuals with cardiometabolic comorbidity, are likely to develop severe COVID-19 disease requiring hospitalisation with potential for a prolonged length of stay (LoS). It may be helpful for health authorities to identify those at risk for prolonged LoS to facilitate appropriate health systems planning. Objectives. To identify hospital admission laboratory parameters associated with a hospital stay >14 days in patients with COVID-19 pneumonia. Methods. A retrospective observational study design was used. Laboratory data were obtained from an SA private laboratory for 642 inpatients with suspected or confirmed COVID-19 pneumonia, comprising 7 months of admission laboratory data from six private hospitals in Johannesburg, Gauteng Province. Results. Of 642 hospital admissions for pneumonia, 497 were confirmed to have COVID-19 infection (reverse transcription-polymerase chain reaction test positive). In the COVID-19-positive group, hospital LoS was prolonged in 35.4% of admissions. Univariate analysis demonstrated an association with the following risk factors for prolonged LoS: older age; male sex; high serum creatinine, sodium (Na), chloride, potassium and urea levels and low estimated glomerular filtration rate; raised white blood cell count, lymphopenia, neutrophilia and an elevated neutrophil-to-lymphocyte ratio (NLR); and elevated levels of D-dimers, interleukin-6 (IL-6), and procalcitonin (PCT). The strongest univariate associations (relative risk (RR) ≥2.0) with a hospital stay >14 days were high Na levels, NRL >18, high PCT levels and IL-6 >40 pg/mL. On multivariable analysis, the following factors remained significantly associated with prolonged LoS: older age (RR 1.015 per year of age; 95% confidence interval (CI) 1.005 - 1.024); hypernatraemia (RR 1.80; 95% CI 1.25 - 2.60); hyperkalaemia (RR 1.61; 95% CI 1.18 - 2.20); and neutrophilia (RR 1.47; 95% CI 1.15 - 1.88). Conclusions. COVID-19 pandemic preparedness requires hospital-based inpatient care to be prioritised in resource-limited settings, and availability of beds and prompt admissions are essential to ensure good clinical outcomes. In this study of COVID-19 patients admitted with pneumonia, multivariable analysis showed older age, hypernatraemia, hyperkalaemia and neutrophilia to be associated with LoS >14 days. This may assist with healthcare systems planning.

Effectiveness of a large-scale, sustained and comprehensive community health worker program in improving population health: the experience of an urban health district in South Africa

IntroductionSouth Africa is an upper middle-income country with wide wealth inequality. It faces a quadruple burden of disease and poor health outcomes, with access to appropriate and adequate health care a challenge for millions of South Africans. The introduction of large-scale, comprehensive community health worker (CHW) programs in the country, within the context of implementing universal health coverage, was anticipated to improve population health outcomes. However, there is inadequate local (or global) evidence on whether such programs are effective, especially in urban settings.MethodsThis study is part of a multi-method, quasi-experimental intervention study measuring effectiveness of a large-scale CHW program in a health district in an urban province of South Africa, where CHWs now support approximately one million people in 280,000 households. Using interviewer administered questionnaires, a 2019 cross-sectional survey of 417 vulnerable households with long-term CHW support (intervention households) are compared to 417 households with no CHW support (control households). Households were selected from similar vulnerable areas from all sub-levels of the Ekurhuleni health district.ResultsThe 417 intervention and control households each had good health knowledge. Compared to controls, intervention households with long-term comprehensive CHW support were more likely to access early care, get diagnosed for a chronic condition, be put on treatment and be well controlled on chronic treatment. They were also more likely to receive a social grant, and have a birth certificate or identity document. The differences were statistically significant for social support, health seeking behavior, and health outcomes for maternal, child health and chronic care.ConclusionA large-scale and sustained comprehensive CHW program in an urban setting improved access to social support, chronic and minor acute health services at household and population level through better health-seeking behavior and adherence to treatment. Direct evidence from households illustrated that such community health worker programs are therefore effective and should be part of health systems in low- and middle-income countries.

Baseline audiological profiling of South African females with cervical cancer: an important attribute for assessing cisplatin-associated ototoxicity

BackgroundCisplatin is a popular antineoplastic agent used to treat cervical cancer in women from low and middle-income countries. Cisplatin treatment is associated with ototoxicity, often resulting in hearing loss. In light of this, it is crucial to conduct baseline audiological assessments prior to treatment initiation in order to evaluate the extent of cisplatin-associated-ototoxicity. Additionally, the identification of inherent risk factors and hearing patterns in specific patient cohorts is needed, especially in South Africa, a middle-income country characterized by the quadruple burden of disease (Human Immunodeficiency Virus (HIV), Tuberculosis (TB), Diabetes and Hypertension).MethodsThis study aimed to describe a profile of risk factors and hearing in a cohort of females with cervical cancer before cisplatin treatment commenced. A descriptive study design that included 82 cervical cancer patients, who underwent audiological evaluation prescribed for ototoxicity monitoring was conducted.ResultsAll participants (n = 82) presented with risk factors (diabetes, hypertension, HIV, and antiretroviral therapy) for cisplatin ototoxicity and/or pre-existing sensorineural hearing loss. High-frequency tinnitus was the most common otological symptom experienced by 25 (31%) participants. Fifty-nine (72%) participants presented with normal hearing, twenty-two (27%) with a sensorineural hearing loss, and 36% were diagnosed with mild hearing loss. Abnormal Distortion Product Otoacoustic Emissions (DPOAE) findings were obtained bilaterally in two participants (2.4%), in the right ear only of another two (2.4%) participants and the left ear of three participants (3.7%). Most participants (94%) had excellent word recognition scores, demonstrating an excellent ability to recognize words within normal conversational levels under optimal listening conditions. Age was significantly associated with hearing loss at all thresholds. Among the co-morbidities, an HIV positive status significantly triggered hearing loss, especially at higher frequencies.ConclusionThis study demonstrated that South African females with cervical cancer present with various co-morbidities, which may predispose them to develop cisplatin-associated -ototoxic hearing loss. Identification of these co-morbidities and hearing loss is essential for the accurate monitoring of cisplatin toxicities. Appropriate management of these patients is pivotal to reduce the adverse effects that hearing impairment can have on an individual’s quality of life and to facilitate informed decision-making regarding the commencement of cisplatin chemotherapy.

Striving for equity: Life orientation resources in South African high schools

As a school subject, life orientation (LO) aims to improve learner well-being, but a lack of classroom resources may be a barrier. We investigated whether classroom resources were equally available for LO educators in fully funded (no-fee) and partially funded (fee-paying) high schools in Tshwane South, South Africa. In this analytical cross-sectional study, LO representatives completed questionnaires about the availability of resources in their schools. Sixty-seven LO representatives completed the questionnaire. No-fee and fee-paying schools had the same availability of government resources and textbooks, but no-fee schools had less access to audio-visual equipment and printed materials. Representatives from both categories of schools were least satisfied with the availability of resources for the topic: Health. In contrast, they thought that the resources for non-health related topics such as career and skills-development were adequate. Representatives from no-fee schools were less satisfied with physical education resources (U (56) = -2.29, p = 0.02). The government’s efforts to redress inequity is evident in the availability of basic resources. However, a lack of health resources is a source of concern in a society that has a quadruple burden of disease.

A retrospective review of speech-language therapy services provided to adult inpatients at a central-level hospital in Gauteng, South Africa.

BackgroundThe quadruple burden of disease (BoD) and multimorbidity reflected in South Africa’s public health sector challenges speech-language therapists (SLTs) to optimise patient management in this context. For planning and delivery of appropriate services, it is important to understand the profile of speech-language therapy (SLT) patients and the public healthcare services provided by SLTs.ObjectivesThis study aimed to describe the prevalence of inpatient adult speech, language and swallowing disorders associated with various medical conditions and South Africa’s BoD, in addition to the target areas and duration of SLT interventions provided at a central public hospital.MethodA retrospective review was conducted on records of 2549 adult inpatients who received SLT services between January 2014 and December 2015 at Chris Hani Baragwanath Academic Hospital. Data, including demographics, medical and SLT diagnoses, and treatment recommendations, were analysed using descriptive and inferential statistics.ResultsNon-communicable diseases (NCDs) were most prevalent (77.48%), with multimorbidity of BoD categories in 29.27% of patients. Cerebrovascular disease (CeVD) comprised 52.45% patients, with CeVD, traumatic brain injury, other neurological conditions, cancer and burns comprising 88.74% patients. More than a third of the patients with CeVD were < 56 years (n = 486; 36.35%). Dysphagia (48.96%), aphasia (30.95%) and dysarthria (23.62%) were the most common, with 44.68% of patients having multiple SLT diagnoses. The number of SLT sessions significantly correlated with SLT comorbidity (rs = 0.4200; p = 0.0000), but not BoD comorbidity (rs = 0.0049; p = 0.8058).ConclusionSpeech-language therapy patients reflected a heavy NCD burden and multimorbidity. Provision of SLT services should take into consideration a profile of increased complexity of medical conditions and SLT diagnoses.

The prevalence, risk factors and outcomes of anaemia in South African pregnant women: a protocol for a systematic review and meta-analysis

BackgroundA significant cause of morbidity and mortality during pregnancy is maternal anaemia. The causes of anaemia and the sequelae are varied, and the prevention and management are public health challenges, especially in resource-limited settings and certain geographic locations. South Africa is plagued by a quadruple burden of disease, with high maternal mortality rates affected by hypertensive disorders of pregnancy, HIV, tuberculosis and neglected tropical diseases. This is most prevalent in people of lower socio-economic status. Poor nutrition, chronic infections, lack of access to health care facilities and poor compliance with micronutrient supplementation all contribute to maternal anaemia. The aim of this study is to systematically map the literature to ascertain the pooled prevalence and associated causes of anaemia in the South African pregnant population, which will enable health care workers and other key stakeholders to more pertinently address Sustainable Development Goal 3 focussing on good health and reducing maternal mortality.MethodsPubMed, CINAHL, EMBASE, EBSCO, Ovid maternity and infant care databases, Cochrane Database of Systematic Reviews, Web of Science and SCOPUS will be searched using the keywords ‘anaemia’, ‘haemoglobin’, ‘pregnancy’, and ‘South Africa’ to conduct a systematic review and meta-analysis to explore, describe and map literature on the distribution and burden of anaemia in pregnant women in South Africa. The reference list of articles selected for review will be scanned for other articles of interest to our study question. Studies published in any language will be included in this review. As there may be differences in sampled populations in South Africa based on geography and sociodemographic factors, a weighted inverse-variance meta-analysis using a random-effects model will be carried out to generate a pooled prevalence estimate. A Funnel plot and Egger’s regression test will be conducted to assess publication bias. Heterogeneity among studies will be checked using I2 to determine dispersion and meta-regression analysis will be performed to investigate the source of heterogeneity. The articles obtained by these searches will be analysed for causative factors, severity and outcomes by a parallel and independent review team, using suitable eligibility criteria. Screening, data extraction and quality appraisal will be conducted independently by two authors. Disagreement will be resolved by independent assessment by a third reviewer. Sub group analysis by region, stage of pregnancy, socio-economic status, severity and cause of anaemia will be conducted if sufficient data is available. Data will be analysed using statistical software and presented in evidence tables and in meta-analytic forest plots.DiscussionThis protocol is developed to systematically review the literature on the prevalence and severity of anaemia, risk factors and outcomes in pregnant women in South Africa. Correlation of factors contributing to the development of anaemia and other disorders during pregnancy will facilitate exploration of appropriate medical and behavioural change interventions implemented within other countries or regions that mitigate risk. This study will assist local health systems to inform public health policies and practises for more favourable maternal and fetal outcomes.Trial registrationThis protocol is registered with PROSPERO (CRD42020157191)

Publics, technologies and interventions in reproduction and early life in South Africa

Despite successful clinical interventions and maternal and child health monitoring for over a century, low and middle-income countries, including South Africa, continue to experience the quadruple burden of disease of high maternal mortality rates and poor infant and child health, non-communicable diseases, infectious diseases, and violence and injury. In this article, we focus on how different kinds of technologies in South Africa are implemented in the ‘first 1000 days’ from conception to early childhood. Some of these interventions, as we discuss, are lifesaving; others are conceptualised as preventing early and longer-term health problems, including cardiometabolic conditions into adulthood and in future generations. Here, we consider the use of routine and specialist technologies in reproduction and early life: scanning and monitoring in pregnancy, caesarean section, extracorporeal membrane oxygenation (ECMO) for very low birth weight infants, and the Road to Health Booklet. Through this focus, we illustrate how ‘publics’ are constituted such that foetal and infant health outcomes are privileged over women’s health, reproductive rights, and public health safety.

Paediatric dysphagia within the context of South Africa’s quadruple burden of disease, seen at a tertiary level hospital

Purpose: To inform service provision, this study explored feeding and swallowing difficulties in children within the context of South Africa’s quadruple burden of disease (BOD) (i.e. conditions characterised as communicable, non-communicable, maternal and/or perinatal and trauma).Method: A retrospective chart review of 1432 paediatric inpatients (under 12 years of age) who met the inclusion criteria of presenting with dysphagia and being referred for speech-language pathology services was conducted.Result: Participants with diagnoses within the maternal and/or perinatal BOD category were noted most frequently (61.2%), followed by non-communicable (59.7%), communicable (43.4%) and trauma (4.2%). The majority of participants were under 1 year of age (82.2%) and 56.2% presented with comorbidities in multiple BOD categories. Mortality was 5.9%, with a higher rate (67.7%) in more complex cases. Mortality was associated with non-communicable BOD (p = 0.001), and maternal and/or perinatal BOD (p = 0.003). Pharyngeal phase swallowing difficulties were a significant risk for mortality (OR = 2.96; 95% CI: 1.01–8.65, p = 0.047).Conclusion: The majority of children with dysphagia presented with multiple comorbidities and were at high risk for mortality. Education and service delivery models should be designed to improve health outcomes and reduce mortality rates.

Validation of a brief mental health screening tool for common mental disorders in primary healthcare.

Integrating care for common mental disorders (CMDs) such as depression, anxiety and alcohol abuse into primary healthcare (PHC) should assist in reducing South Africa (SA)'s quadruple burden of disease. CMDs compromise treatment adherence, health behaviour change and self-management of illnesses. Appropriate identification of mental disorders in primary care can be facilitated by brief, easy-to-administer screening that promotes high specificity. To establish the criterion-based validity of a seven-item Brief Mental Health (BMH) screening tool for assessing positive symptoms of CMDs in primary care patients. A total of 1 214 participants were recruited from all patients aged ≥18 years visiting 10 clinics as part of routine care in the Newcastle subdistrict of Amajuba District in KwaZulu-Natal Province, SA, over a period of 2 weeks. Consenting patients provided basic biographical information prior to screening with the BMH tool. PHC nurses remained blind to this assessment. PHC nurse-initiated assessment using the Adult Primary Care (APC) guidelines was the gold standard against which the performance of the BMH tool was compared. A specificity standard of 80% was used to establish cut-points. Specificity was favoured over sensitivity to ensure that those who did not have CMD symptoms were excluded, as well as to reduce over-referrals. Of the participants, 72% were female. The AUD-C (alcohol abuse) performed well (area under the curve (AUC) 0.91 (95% confidence interval (CI) 0.88 - 0.95), cut-point ≥4, Cronbach alpha 0.87); PHQ-2 (depression) performed reasonably well (AUC 0.72 (95% CI 0.65 - 0.78), cut-point ≥3, alpha 0.71); and GAD-2 (anxiety) performance was acceptable (AUC 0.69 (95% CI 0.58 - 0.80), cut-point ≥3, alpha 0.62). Using the higher cut-off scores, patients who truly did not have CMD symptoms had negative predictive values (NPVs) of &gt;90%. Overall, 26% of patients had CMD positive symptoms relative to 8% using the APC guidelines. Using a higher specificity index, the positive predictive value and NPV show that at higher cut-point values the BMH not only helpsidentify individuals with alcohol misuse, depression and anxiety symptoms but also identifies a majority of those who do not have symptoms (true negatives), thus not overburdening nurses with false positives needing assessment. Research is needed to assess whether use of such a short and valid screening tool is generalisable to other clinic contexts as well as how mental health screening should best be introduced into routine clinic functioning and practice.

Challenges Facing Home-Based Caregivers in the Management of Health Care Risk Waste.

The quadruple burden of diseases, early discharge from hospital and hospital at home have resulted in home-based care services becoming a requirement in South Africa. These home-based care services generate a significant amount of health care risk waste that is mismanaged. More attention is given to the health care risk waste generated in hospitals and clinics than to health care risk waste generated by home-based caregivers. Therefore, this study investigates the health care risk waste management practices by home-based caregivers. The study adopted a mixed research approach, qualitative and quantitative methods, using a literature review, interviews, and questionnaires as means of data collection. Results show that there are different types of health care risk waste generated as a result of different activities performed by home-based caregivers, but that the waste was found to be managed in an unsafe manner. The majority of households receiving home-based care did not have basic sanitation facilities such as toilets, running water and waste removal services, aggravating the issue of health care risk waste mismanagement. The study recommends a new policy framework that will lead to safe management practices of generated health care risk waste to be adopted by home-based caregivers.

Accelerated nutrition transition in the North West Province of South Africa: results from the Prospective Urban and Rural Epidemiology (PURE-NWP-SA) cohort study, 2005 to 2010.

South Africa (SA) is in the midst of a health transition characterized by a quadruple burden of diseases and a nutrition transition. The existing nutrition transition in SA, accompanied by the coexistence of under- and overnutrition in the population, motivated the present study. Its objectives were to measure and report the changes in nutrient intakes of rural and urban black Africans over time to assess the impact of urbanization and modernization of lifestyles on dietary intakes and non-communicable disease (NCD) risk. The PURE-NWP-SA study recruited 2000 black South African volunteers aged 35-70 years in 2005, of which detailed nutrient intakes from 1858 participants were available. In 2010 nutrient intakes of a cohort of 1154 participants were measured. Median energy intake increased over time. In 2010, rural participants consumed the amount of energy (men 9·7 MJ/d; women 9·1 MJ/d) that urban participants consumed in 2005 (men 9·9 MJ/d; women 9·0 MJ/d). The nutrition transition was characterized by increases in the percentage of energy from animal protein, total fat (rural men and women), saturated (not urban women) and monounsaturated fat, as well as added sugar. Despite the higher energy intake, not all the participants met total micronutrient needs in 2010. The PURE nutrient intake data confirmed that the nutrition transition in the North West Province of SA is extremely rapid in rural areas. The shift towards higher energy intakes, an animal food-based diet, higher intakes of fat and lower intake of fibre, at the cost of lower plant protein and starchy food intakes, could increase the risk of NCD.

Establishing a Health Promotion and Development Foundation in South Africa

South Africa has a 'quadruple burden of disease'. One way to reduce this burden, and address the social determinants of health and social inequity, could be through health promotion interventions driven by an independent Health Promotion and Development Foundation (HPDF). This could provide a framework to integrate health promotion and social development into all government and civil society programmes. On priority issues, the HPDF would mobilise resources, allocate funding, develop capacity, and monitor and evaluate health promotion and development work. Emphasis would be on reducing the effects of poverty, inequity and unequal development on disease rates and wellbeing. The HPDF could also decrease the burden on the proposed National Health Insurance (NHI) system. We reflect on such foundations in other countries, and propose a structure for South Africa's HPDF and a dedicated funding stream to support its activities. In particular, an additional 2% levy on alcohol and tobacco products is proposed to be utilised to fund the HPDF.

The Care Coordination Program: a virtually integrated care delivery model for complex, high-needs patients

Background The South African healthcare sector is fragmented. The increasing prominence of non-communicable, or chronic, diseases in both the private and public healthcare sectors contributes to the country’s complex and costly “quadruple burden of disease” (the others being HIV/AIDS, tuberculosis, maternal and child mortality, and violence). These chronic diseases, once they have progressed, are inherently difficult to manage due to their underlying psychosocial components and their characteristically complex co-morbidities. High costs, without the desired improved clinical outcomes, are common. Elsewhere in the world, such as in the United States, where similar fragmented systems exist, new care-delivery models have emerged to better manage patients with complex conditions. These include vertical payerprovider integration, patient-centered medical homes, and accountable care organizations. Enablers of similar structural reforms are lacking in South Africa, however, where regulatory rules bar the employment of salaried doctors by hospital networks. Moreover, a looming nation-wide dearth of healthcare professionals diminishes the potential for systemic structural changes to the status quo. Discovery Health (DH) is the country’s largest private healthcare payer, providing health insurance coverage to over 2.5 million people. The Care Co-ordination Program (CCP) is DH’s response to the fragmented care received by its members who present with complex healthcare needs, including psychological and social vulnerabilities. Methods The target DH population of members likely to benefit in the CCP is identified geographically using the Johns Hopkins Adjusted Clinical Group tool. This tool categorizes members into Resource Utilization Bands. Further, a Disease Burden Index (DBI) is employed to narrow the focus of the CCP to DH members with the greatest complexity and highest disease burden. The DBI for the CCP population is 17.071 compared to a significantly lower DBI for the general DH population of 1.024 (see Figure 1). Sub-acute service providers in the identified highneeds geographic areas who meet structural, service and management criteria are contracted with DH to participate in a CCP network. At the time of a patient’s admission into an acute facility, a DH care recruiter employs pre-set clinical, social, and psychological entry criteria combined with a FIM (Functional Independence Measure) score to identify patients at risk of sub-optimal quality of care associated with repeated costly admissions. The identified patients are voluntarily enrolled in the CCP and, at this point, a DH care co-coordinator joins the care team of the contracted service provider. The care co-coordinator ensures that the patient’s unique needs are carefully and methodically addressed by the service provider’s interdisciplinary care team. Integrating the family into the care plan is central to ensuring a successful transition to the home. The care co-coordinator shares the transition plan and the patient’s electronic medical record with all involved providers, thus ensuring the co-ordination of care following discharge. The co-coordinator is a valuable resource for the patient, managing vulnerabilities during the transition to home and community. * Correspondence: roshinin@discovery.co.za Risk and Quality Management, Discovery Health, Sandton, 2146, South Africa Naidoo and Steenkamp BMC Health Services Research 2011, 11(Suppl 1):A18 http://www.biomedcentral.com/1472-6963/11/S1/A18

A situational analysis for the implementation of the National School Health Policy in KwaZulu-Natal

The South African National School Health Policy was launched in 2003 to improve pupils' health by linking school visits by nurses and other health providers with the intersectoral collaboration required for health promoting schools. In KwaZulu-Natal, the policy required that various parties collaborate in order to ensure the successful implementation of the policy. This study examines the status of provincial departments and district level groups and their capacity to contribute to this partnership. It is a situational analysis that includes interviews, a questionnaire and focus group discussions. The results reveal issues that need addressing before the policy can be successfully implemented, including staffing, transport for the School Health Teams and further training of these teams and the teachers. Given the health issues faced by South Africans, especially the quadruple burden of disease, it is imperative that the School Health Policy be comprehensively implemented in KwaZulu-Natal.

The state of public health

It has impact on all levels of society in every country, whether rich or poor, eastern or western, big or small. Patterns of diseases can be influenced by and in turn influence human behaviour, socio-economic factors and health systems of a country. At one end of the spectrum, communicable diseases such as tuberculosis, HIV and malaria cause extensive disease and have significant public health implications, particularly in developing countries. On the other hand, non-communicable diseases such as diabetes, obesity and hypertension are gradually becoming a silent killer not only in developed but also in developing countries. Countries like South Africa are now facing a quadruple burden of diseases which is crippling its already overstretched health system.
