The Burden of Type 2 Diabetes on the Productivity and Economy in Sub-Saharan Africa: A Life Table Modelling Analysis from a South African Perspective.

BACKGROUND AND AIM: The prevalence of type 2 diabetes (T2D) is rapidly increasing in Sub-Saharan Africa (SSA). T2D increases the risk of premature death and reduces quality of life and work productivity. This population life table modelling analysis evaluated the impact of T2D in terms of productivity-adjusted life years (PALYs) on the South African working-age population. RESEARCH DESIGN AND METHODS: Life table modelling was employed to simulate the follow-up of individuals aged 20-65 with T2D in South Africa (SA). Two life table models were developed to simulate health outcomes for a SA cohort with and without diabetes. The difference in the number of deaths, years of life lost (YLL), and PALYs lost between the two cohorts represented the burden of diabetes. Scenarios were simulated in which the proportions of gross domestic productivity (GDP), productivity indices, labour force dropout, and mortality risk trends were adjusted to lower and upper uncertainty bounds. Data were sourced from the International Diabetes Federation, Statistics SA, and both publicly available and published sources. We utilised the World Health Organization (WHO) standard annual discount rate of 3% for YLL and PALYs. RESULTS: In 2019, an estimated 9.5% (7.68% men and 11.37% women) or 3.2 million total working-age people had T2D in SA. Simulated follow-up until retirement predicted 669,427 excess mortality, a loss of 6.2 million years of life (9.3%) and 13 million PALYs (30.6%) in SA. On average, this resulted in 3.1 PALYs lost per person. Based on the GDP per full-time employee in 2019, the PALYs loss equated to US$223 billion, or US$69,875 per person. CONCLUSIONS: This study emphasises the significant impact of T2D on society and the economy. Relatively modest T2D prevention and treatment management enhancement could lead to substantial economic benefits in SA.

A cross-sectional study of knowledge, attitudes, barriers and practices of cervical cancer screening among nurses in selected hospitals in the Eastern Cape Province, South Africa.

BACKGROUND: Cervical cancer is a preventable but highly prevalent cancer in many low -and middle-income countries including South Africa. Cervical cancer outcomes can be improved with improved vaccination, a well-coordinated and efficient screening programme, increased community awareness and uptake, and increased knowledge and advocacy of health professionals. This study therefore aimed to ascertain the knowledge, attitudes, practices and barriers of cervical cancer screening among nurses of selected rural hospitals in South Africa. METHODS: A quantitative cross-sectional study was conducted in five hospitals in the Eastern Cape Province of South Africa between October and December 2021. A self-administered questionnaire was used to assess demographic characteristics of nurses and cervical cancer knowledge, attitudes, barriers and practices. A knowledge score of 65% was deemed adequate. Data were captured in Microsoft Excel Office 2016 and exported to STATA version 17.0 for analysis. Descriptive data analyses were used to report the results. RESULTS: A total of 119 nurses participated in the study with just under two thirds (77/119, 64.7%) being professional nurses. Only 15.1% (18/119) of participants were assessed as having obtained a good knowledge score of ≥ 65%. The majority of these (16/18, 88.9%) were professional nurses. Of the participants with a good knowledge score, 61.1% (11/18) were from Nelson Mandela Academic Hospital, the only teaching hospital studied. Cervical cancer was deemed to be a disease of public health importance by 74.0% (88/119). However, only 27.7% (33/119) performed cervical cancer screening. Most of the participants (116/119, 97.5%) had an interest of attending more cervical cancer training. CONCLUSION: The majority of nurse participants did not have adequate knowledge about cervical cancer and screening, and few performed screening tests. Despite this, there is a high level of interest in being trained. Meeting these training needs is of utmost importance to implementing a comprehensive cervical cancer screening programme in South Africa.

Health system costs of rheumatic heart disease care in South Africa.

BACKGROUND: Rheumatic Heart Disease (RHD) is a disease of poverty that is neglected in developing countries, including South Africa. Lack of adequate evidence regarding the cost of RHD care has hindered national and international actions to prevent RHD related deaths. The objective of this study was to estimate the cost of RHD-related health services in a tertiary hospital in the Western Cape, South Africa. METHODS: The primary data on service utilisation were collected from a randomly selected sample of 100 patient medical records from the Global Rheumatic Heart Disease Registry (the REMEDY study) - a registry of individuals living with RHD. Patient-level clinical data, including, prices and quantities of medications and laboratory tests, were collected from the main tertiary hospital providing RHD care. All annual costs from a health system perspective were estimated in 2017 (base year) in South African Rand (ZAR) using a combination of ingredients and step-down costing approaches and later converted to United States dollars (USD). Step-down costing was used to estimate provider time costs and all other facility costs such as overheads. A 3% discount rate was also employed in order to allow depreciation and opportunity cost. We aggregated data to estimate the total annual costs and the average annual per-patient cost of RHD and conducted a one-way sensitivity analysis. RESULTS: The estimated total cost of RHD care at the tertiary hospital was USD 2 million (in 2017 USD) for the year 2017, with surgery costs accounting for 65%. Per-patient, average annual costs were USD 3900. For the subset of costs estimated using the ingredients approach, outpatient medications, and consumables related to cardiac catheterisation and heart valve surgery were the main cost drivers. CONCLUSIONS: RHD-related healthcare consumes significant tertiary hospital resources in South Africa, with annual per-patient costs higher than many other non-communicable and infectious diseases. This analysis supports the scaling up of primary and secondary prevention programmes at primary health centers in order to reduce future tertiary care costs. The study could also inform resource allocation efforts and provide cost estimates for future studies of intervention cost-effectiveness.
