There is an increasing recognition that non communicable diseases impose large economic costs on households, societies and nations. However, not much is known about the magnitude of diabetes expenditure in African countries and to the best of our knowledge no systematic assessment of the literature on diabetes costs in Africa has been conducted. The aim of this paper is to capture the evidence on the cost of diabetes in Africa, review the methods used to calculate costs and identify areas for future research. A desk search was conducted in Pubmed, Medline, Embase, and Science direct as well as through other databases, namely Google Scholar. The following eligibility criteria were used: peer reviewed English articles published between 2006 and 2016, articles that reported original research findings on the cost of illness in diabetes, and studies that covered at least one African country. Information was extracted using two data extraction sheets and results organized in tables. Costs presented in the studies under review are converted to 2015 international dollars prices (I$). Twenty six articles are included in this review. Annual national direct costs of diabetes differed between countries and ranged from I$3.5 billion to I$4.5 billion per annum. Indirect costs per patient were generally higher than the direct costs per patient of diabetes. Outpatient costs varied by study design, data source, perspective and healthcare cost categories included in the total costs calculation. The most commonly included healthcare items were drug costs, followed by diagnostic costs, medical supply or disposable costs and consultation costs. In studies that reported both drug costs and total costs, drug costs took a significant portion of the total costs per patient. The highest burden due to the costs associated with diabetes was reported in individuals within the low income group. Estimation of the costs associated with diabetes is crucial to make progress towards meeting the targets laid out in Sustainable Development Goal 3 set for 2030. The studies included in this review show that the presence of diabetes leads to elevated costs of treatment which further increase in the presence of complications. The cost of drugs generally contributed the most to total direct costs of treatment. Various methods are used in the estimation of diabetes healthcare costs and the costs estimated between countries differ significantly. There is room to improve transparency and make the methodologies used standard in order to allow for cost comparisons across studies.

South Africa faces an epidemic of chronic non-communicable diseases (NCDs), yet national surveillance is limited due to the lack of recent data. We used data from the first comprehensive national survey on NCDs—the South African National Health and Nutrition Examination Survey (SANHANES-1 (2011–2012))—to evaluate the prevalence of and health system response to diabetes through a diabetes care cascade. We defined diabetes as a Hemoglobin A1c equal to or above 6.5% or currently on treatment for diabetes. We constructed a diabetes care cascade by categorizing the population with diabetes into those who were unscreened, screened but undiagnosed, diagnosed but untreated, treated but uncontrolled, and treated and controlled. We then used multivariable logistic regression models to explore factors associated with diagnosed and undiagnosed diabetes. The age-standardized prevalence of diabetes in South Africans aged 15+ was 10.1%. Prevalence rates were higher among the non-white population and among women. Among individuals with diabetes, a total of 45.4% were unscreened, 14.7% were screened but undiagnosed, 2.3% were diagnosed but untreated, 18.1% were treated but uncontrolled, and 19.4% were treated and controlled, suggesting that 80.6% of the diabetic population had unmet need for care. The diabetes care cascade revealed significant losses from lack of screening, between screening and diagnosis, and between treatment and control. These results point to significant unmet need for diabetes care in South Africa. Additionally, this analysis provides a benchmark for evaluating efforts to manage the rising burden of diabetes in South Africa.

The health sectors in many low- and middle-income countries have been characterized in recent years by extensive private sector activity. This has been complemented by increasing public–private linkages, such as the contracting-out of selected services or facilities, development of new purchasing arrangements, franchising and the introduction of vouchers. Increasingly, however, experience with the private sector has indicated a number of problems with the quality, price and distribution of private health services, and thus led to a growing focus on the role of government in regulation. This paper presents the existing network of regulations governing private activity in the health sectors of Tanzania and Zimbabwe, and their appropriateness in the context of emerging market realities. It draws on a comparative mapping exercise reviewing the complexity of the variables currently being regulated, the level of the health system at which they apply, and the specific instruments being used. Findings indicate that much of the existing regulation occurs through legislation. There is still very much a focus on the ‘social’ rather than ‘economic’ aspects of regulation within the health sector. Recent changes have attempted to address aspects of private health provision, but some very key gaps remain. In particular, current regulations in Tanzania and Zimbabwe: (1) focus on individual inputs rather than health system organizations; (2) aim to control entry and quality rather than explicitly quantity, price or distribution; and (3) fail to address the market-level problems of anti-competitive practices and lack of patient rights. This highlights the need for additional measures to promote consumer protection and address the development of new private markets such as for health insurance or laboratory and other ancillary services.

Occupational hazards, injuries and diseases are a major concern among police officers, including in Sub-Saharan Africa. However, there is limited locally relevant literature for guiding policy for the South African Police Service (SAPS). The purpose of this review was to describe the occupational hazards, injuries and diseases affecting police officers worldwide, in order to benchmark policy implications for the SAPS. We conducted a systematic review of studies using Google Scholar, PubMed and Scopus. A total of 36 studies were included in this review. Six revealed that police officers’ exposure to accident hazards may lead to acute or chronic injuries such as sprains, fractures or even fatalities. These hazards may occur during driving, patrol or riot control. There were two studies, which confirmed physical hazards such as noise induced hearing loss (NIHL), due to exposure to high levels of noise. Three studies on chemical hazards revealed that exposure to high concentrations of carbon dioxide and general air pollution was associated with cancer, while physical exposure to other chemical substances was linked to dermatitis. Four studies on biological hazards demonstrated potential exposure to blood borne diseases from needle stick injuries (NSIs) or cuts from contaminated objects. One study on ergonomic hazards showed that musculoskeletal disorders can result from driving long distances and lifting heavy objects. There were 15 studies that indicated psychological hazards such as post-traumatic stress disorder (PTSD) as well as stress. Moreover, four studies were conducted on organizational hazards including burnout, negative workplace exposure and other factors. This review outlined the global impact of occupational hazards, injuries and diseases in the police force. It served as a benchmark for understanding the policy implications for South Africa, where there is paucity of studies on occupational health and safety.

Healthcare workers are an essential element in the functionality of the health system. However, the health workforce impact on health systems tends to be overlooked. Countries within the Sub-Saharan region such as the six in the East African Community (EAC) have weak and sub-optimally functioning health systems. As countries globally aim to attain Universal Health Coverage and the Sustainable Development Goal 3, it is crucial that the significant role of the health workforce in this achievement is recognized. In this systematic review, we aimed to synthesise the determinants of motivation as reported by healthcare workers in the EAC between 2009 and 2019. A systematic search was performed using four databases, namely Cochrane library, EBSCOhost, ProQuest and PubMed. The eligible articles were selected and reviewed based on the authors’ selection criteria. A total of 30 studies were eligible for review. All six countries that are part of the EAC were represented in this systematic review. Determinants as reported by healthcare workers in six countries were synthesised. Individual-level-, organizational/structural- and societal-level determinants were reported, thus revealing the roles of the healthcare worker, health facilities and the government in terms of health systems and the community or society at large in promoting healthcare workers’ motivation. Monetary and non-monetary determinants of healthcare workers’ motivation reported are crucial for informing healthcare worker motivation policy and health workforce strengthening in East Africa.
