This article, from Human Resources for Health, examines the experiences of using substitute health workers (SHW) in Africa. The review focuses mainly on physicians and reviews data from Tanzania, Congo, Kenya, Malawi, Mozambique, Zambia and Ghana. Findings demonstrate the cost-effectiveness of using SHWs and higher rates of retention within countries and in rural communities. However, problems are also identified, including the potential among SHWs for poor clinical decision making and lack of adherence to clinical regulations.

Using mid-level cadres as substitutes for health professionals
Using mid-level cadres as substitutes for internationally mobile health professionals in Africa
Substitute health workers are cadres who take on some of the functions and roles normally reserved for internationally recognized health professionals such as doctors, pharmacists and nurses but who usually receive shorter pre-service training and possess lower qualifications. The findings raise interest in expanding the use of substitute cadres, as the demands of expanding access to services such as antiretroviral treatment requires substantial human resources capacity.
Using primary health care (PHC) workers and key informants for community based detection of blindness in children in Southern Malawi
Kalua K, Ng’ongola RT, Mbewe F and Gilbert C: Human Resources for Health: 10(37), 27 September 2012
This study compared the effectiveness of trained Health Surveillance Assistants (HSAs) versus trained volunteer Key Informants (KIs) in identifying blind children in southern Malawi. A cluster community based study was conducted in Mulanje district, population 435 753. Six clusters each with a population of approximately 70,000 to 80,000, 42% of whom were children were identified and randomly allocated to either HSA or KI training. A total of 59 HSAs and 64 KIs were trained. HSAs identified five children of whom two were confirmed as blind (one blind child per 29.5 HSAs trained). On the other hand, the KIs identified a total of 158 children of whom 20 were confirmed blind (one blind child per 3.2 KIs trained). More blind boys than girls were identified (77.3% versus 22.7%) respectively. Key Informants were found to be much better at identifying blind children than HSAs, even though both groups identified far fewer blind children compared with WHO estimates. HSAs reported lack of time as a major constraint in identifying blind children. Based on these findings using HSAs for identifying blind children would not be successful in Malawi, the authors argue. Gender differences need to be addressed in all childhood blindness programs to counteract the imbalance.
Using staffing ratios for workforce planning: Evidence on nine allied health professions
Cartmill L, Comans TA, Clark MJ, Ash S and Sheppard L: Human Resources for Health 10(2), 1 February 2012
The aim of this study was to identify workforce ratios in nine allied health professions and to identify whether these measures are useful for planning allied health workforce requirements. A systematic literature search using relevant MeSH headings of business, medical and allied health databases and relevant grey literature for the period 2000-2008 was undertaken. Twelve articles were identified which described the use of workforce ratios in allied health services. Only one of these was a staffing ratio linked to clinical outcomes. The most comprehensive measures were identified in rehabilitation medicine. The authors conclude that evidence for use of staffing ratios for allied health practitioners is scarce and lags behind the fields of nursing and medicine.
Vertical funding, non-governmental organisations, and health system strengthening: perspectives of public sector health workers in Mozambique
Mussa AH, Pfeiffer J, Gloyd SS, Sherr K: Human Resources for Health 11(26), 14 June 2013
In this paper, the authors explored the perspectives and experiences of key Mozambican public sector health managers who coordinate, implement, and manage the myriad donor-driven projects and agencies. Over a four-month period, they conducted 41 individual qualitative interviews with key Ministry workers at three levels in the Mozambique national health system, using open-ended semi-structured interview guides, as well as reviewed planning documents. All respondents emphasized the value and importance of international aid and vertical funding to the health sector and each highlighted program successes that were made possible by recent increased aid flows. However, three serious concerns emerged: 1) difficulties coordinating external resources and challenges to local control over the use of resources channeled to international private organizations; 2) inequalities created within the health system produced by vertical funds channeled to specific services while other sectors remain under-resourced; and 3) the exodus of health workers from the public sector health system provoked by large disparities in salaries and work. The vertical approach starved the Ministry of support for its administrative functions. Few studies have addressed the growing phenomenon of “internal brain drain” in Africa which proved to be of greater concern to Mozambique’s health managers.
Vertical funding, non-governmental organisations, and health system strengthening: Perspectives of public sector health workers in Mozambique
Mussa AH, Pfeiffer J, Gloyd SS, Sherr K: Human Resources For Health 11(26), 14 June 2013
The authors of this paper consider the perspectives and experiences of key Mozambican public sector health managers who coordinate, implement, and manage a wide variety of donor-driven projects and agencies. Over a four-month period, they conducted 41 individual qualitative interviews with key Ministry workers at three levels in the Mozambique national health system, using open-ended semi-structured interview guides, as well as reviewed planning documents. All respondents emphasized the value and importance of international aid and vertical funding to the health sector and each highlighted program successes that were made possible by recent increased aid flows. However, three serious concerns emerged: difficulties coordinating external resources and challenges to local control over the use of resources channeled to international private organisations; inequalities created within the health system produced by vertical funds channeled to specific services while other sectors remain under-resourced; and the exodus of health workers from the public sector health system provoked by large disparities in salaries and work. The vertical approach starved the Ministry of support for its administrative functions.
Wastage in the health workforce: the experience of African countries
"Sub-Saharan Africa faces a human resources crisis in the health sector. Over the past two decades its population has increased substantially, with a significant rise in the disease burden due to HIV/AIDS and recurrent communicable diseases and an increased incidence of noncommunicable diseases. This increased demand for health services is met with a rather low supply of health workers, but this notwithstanding, sub-Saharan African countries also experience significant wastage of their human resources stock."
Waste disposal - local information makes hygiene promotion more effective
Over three million children die from diarrhoea every year in developing countries and a third of the world's population is infected with parasitic worms. Simple improvements in hygiene could drastically cut infection rates. But what is the best way to develop hygiene promotion programmes? How can health promoters identify target populations and risk factors?
Weak Links in the Chain II: A Prescription for Health Policy in Poor Countries
In an earlier article, the authors outline some reasons for the disappointingly small effects of primary health care programs and identified two weak links standing between spending and increased health care. The first was the inability to translate public expenditure on health care into real services due to inherent difficulties of monitoring and controlling the behavior of public employees. The second was the "crowding out" of private markets for health care, markets that exist predominantly at the primary health care level. This article presents an approach to public policy in health that comes directly from the literature on public economics. It identifies two characteristic market failures in health. The first is the existence of large externalities in the control of many infectious diseases that are mostly addressed by standard public health interventions. The second is the widespread breakdown of insurance markets that leave people exposed to catastrophic financial losses. Other essential considerations in setting priorities in health are the degree to which policies address poverty and inequality and the practicality of implementing policies given limited administrative capacities. Priorities based on these criteria tend to differ substantially from those commonly prescribed by the international community.
What do community health workers have to say about their work, and how can this inform improved programme design? A case study with CHWs within Kenya
Oliver M; Geniets A; Winters N; Rega I; Mbae S: Global Health Action 8, May 2015, doi: http://dx.doi.org/10.3402/gha.v8.27168
Community health workers (CHWs) are often spoken about or for, but there is little evidence of CHWs’ own characterisation of their practice. This paper addresses this issue. A case study approach was undertaken in a series of four steps. Firstly, groups of CHWs from two communities met and reported what their daily work consisted of. Secondly, individual CHWs were interviewed so that they could provide fuller, more detailed accounts of their work and experiences; in addition, community health extension workers and community health committee members were interviewed, to provide alternative perspectives. Thirdly, notes and observations were taken in community meetings and monthly meetings. The data were then analysed thematically, creating an account of how CHWs describe their own work, and the tensions and challenges that they face. CHWs’ accounts of both successes and challenges involved material elements: leaky tins and dishracks evidenced successful health interventions, whilst bicycles, empty first aid kits and recruiting stretcher bearers evidenced the difficulties of resourcing and geography they are required to overcome. CHWs described their work was as healthcare generalists, working to serve their community and to integrate it with the official health system. Their work involves referrals, monitoring, reporting and educational interactions. Whilst they face problems with resources and training, their accounts show that they respond to this in creative ways, working within established systems of community power and formal authority to achieve their goals, rather than falling into a ‘deficit’ position that requires remedial external intervention. Their work is widely appreciated, although some households do resist their interventions, and figures of authority sometimes question their manner and expertise. The material challenges that they face have both practical and community aspects, since coping with scarcity brings community members together. The authors suggest that programmes co-designed with CHWs will be easier to implement because of their relevance to their practices and experiences, whereas those that seek to use CHWs as an instrument to implement external priorities are likely to disrupt their work.
