Challenges facing National Health Research Systems in the WHO African Region

Many countries in the African region do not have functional national health research systems (NHRS) that generate, disseminate, uses, and archives health-related knowledge/ideas in published form (hard, electronic or audio forms). In such countries, death of each modern or traditional health practitioner constitutes a permanent loss of a library of knowledge, ideas, innovations and inventions. The WHO African Advisory Committee on Health Research and Development (AACHRD) has attributed the fragility of NHRS in the Region to poor environment for research, inadequate manpower, inadequate infrastructures and facilities, inaccessibility to modern technology, and lack of funds. The weak and uncoordinated NHRS partly explain the poor overall performance of majority of national health systems in the Region. Continued fragility of NHRS can be attributed to lack of implementation of the WHO Regional Committee for Africa and the World Health Assembly resolutions on health research. This paper urges African countries, to fully implement the contents of those resolutions, for substantive health research outputs to share with the rest of the world at the next Ministerial Summit on Research for Health, which will take place in the African Region in 2008.

Predictors of toilet ownership in South Africa

Background: To date no study in South Africa (to our knowledge) has attempted to isolate the key socio-economic variables associated with toilet ownership.Objective: To contribute towards bridging knowledge-gap by identifying the key predictors of toilet ownership.Design: Cross-sectional national household sample survey.Setting: South African Health Inequalities Survey, 1994.Subjects: Three thousand seven hundred and ninety six respondents aged between 16 and 64 years.Interventions: Non-intervention qualitative response econometric study.Main outcome measures: Respondent ownership of a toilet in their house (or compound).Results: The study revealed that respondents’ area of residence, health insurance coverage, income, age (in years), gender, level of education, health education, racial group, and employment status have statistically significant positive impact on the likelihood of toiletownership.Conclusion: Any government policies geared at improving living conditions (incomes, education, health education, and employment opportunities) for the less-well-to-do in urban and rural areas would increase the likelihood of toilet ownership in South Africa

A rapid assessment of district health systems in six countries of the WHO African regions

Objectives: This paper reviews the adequacy of inputs and processes at district level to support outputs and outcomes of service delivery at district level using a rapid assessment. The outputs included in this study are those considered essential for the attainment of the Health related Millennium Development Goals(MDGs).Data sources: A questionnaire based rapid District Health Systems assessment was conducted among six African countries during the year 2007.Study selections: The study took place in a random sample of six out of 19 English speaking countries of the WHO African region. These countries are Ghana, Liberia, Namibia, Nigeria, Sierra Leone and Uganda.Data extraction: The data was extracted from the questionnaires, entered and analysed in Excel spreadsheet.Data synthesis: In spite of the variability in quality and completeness of reporting on the selected parameters, this paper does indicate that according to country norms and standards, the inputs and processes are insufficient to lead to acceptable outputs and outcomes, especially those related to the MDGs. An important point to note is that comparability across countries is made on the basis of individual country norms and standards. Implicit in this assessment is that country norms and standards are reasonable and are appropriate for the attainment of the MDGs. However reasonable the country norms and standard are, it is unlikely that the low resource base as well as weak organisational and managerial capacities in most countries will support effectively the attainment of the MDGs.Conclusion: Most countries manage to offer the essential health services at all levels of care despite the relatively low level of inputs. However, their level of quality and equity is debatable. The general trend is that provision of the essential health services is more at the higher levels of care prompting concerns for the populations served at lower levels of care. There is also a tendency to have wide variations in the performance of service delivery geographically as well as at the different levels of the health systems. This paper recommends further exploration of the impactof focusing on improving quality of existing health services while increasing quantity of service delivery points to achieve higher coverage of essential health services

Effects of maternal mortality on gross domestic product (GDP) in the WHO African region

WHO African region has got the highest maternal mortality rate compared to the other five regions. Maternal mortality is hypothesized to have significantly negative effect on the gross domestic product (GDP). The objective of the current study was to estimate the loss in GDP attributable to maternal mortality in the WHO African Region. The burden of maternal mortality on GDP was estimated using a doublelog econometric model. The analysis is based on cross-sectional data for 45 of the 46 Member States in the WHO African Region. Data were obtained from UNDP and the World Bank publications. All the explanatory variables included in the doublelog model were found to have statistically significant effect on per capita gross domestic product (GDP) at 5% level in a t-distribution test. The coefficients for land (D), capital (K), educational enrolment (EN) and exports (X) had a positive sign; while labor (L), imports (M) and maternal mortality rate (MMR) were found to impact negatively on GDP. Maternal mortality of a single person was found to reduce per capita GDP by US$ 0.36 per year. The study has demonstrated that maternal mortality has a statistically significant negative effect on GDP. Thus, as policy-makers strive to increase GDP through land reform programs, capital investments, export promotion and increase in educational enrolment, they should always remember that investments in maternal mortalityreducing interventions promises significant economic returns.

Economic burden of cholera in the WHO African region

<p>Abstract</p> <p>Background</p> <p>In 2007, various countries around the world notified 178677 cases of cholera and 4033 cholera deaths to the World Health Organization (WHO). About 62% of those cases and 56.7% of deaths were reported from the WHO African Region alone. To date, no study has been undertaken in the Region to estimate the economic burden of cholera for use in advocacy for its prevention and control. The objective of this study was to estimate the direct and indirect cost of cholera in the WHO African Region.</p> <p>Methods</p> <p>Drawing information from various secondary sources, this study used standard cost-of-illness methods to estimate: (a) the direct costs, i.e. those borne by the health-care system and the family in directly addressing cholera; and (b) the indirect costs, i.e. loss of productivity caused by cholera, which is borne by the individual, the family or the employer. The study was based on the number of cholera cases and deaths notified to the World Health Organization by countries of the WHO African Region.</p> <p>Results</p> <p>The 125018 cases of cholera notified to WHO by countries of the African Region in 2005 resulted in a real total economic loss of US$39 million, US$ 53.2 million and US$64.2 million, assuming a regional life expectancies of 40, 53 and 73 years respectively. The 203,564 cases of cholera notified in 2006 led to a total economic loss US$91.9 million, US$128.1 million and US$156 million, assuming life expectancies of 40, 53 and 73 years respectively. The 110,837 cases of cholera notified in 2007 resulted in an economic loss of US$43.3 million, US$60 million and US$72.7 million, assuming life expectancies of 40, 53 and 73 years respectively.</p> <p>Conclusion</p> <p>There is an urgent need for further research to determine the national-level economic burden of cholera, disaggregated by different productive and social sectors and occupations of patients and relatives, and national-level costs and effectiveness of alternative ways of scaling up population coverage of potable water and clean sanitation facilities.</p

Using data envelopment analysis to measure the extent of technical efficiency of public health centres in Ghana

<p>Abstract</p> <p>Background</p> <p>Data Envelopment Analysis (DEA) has been used to analyze the efficiency of the health sector in the developed world for sometime now. However, in developing economies and particularly in Africa only a few studies have applied DEA in measuring the efficiency of their health care systems.</p> <p>Methods</p> <p>This study uses the DEA method, to calculate the technical efficiency of 89 randomly sampled health centers in Ghana. The aim was to determine the degree of efficiency of health centers and recommend performance targets for the inefficient facilities.</p> <p>Results</p> <p>The findings showed that 65% of health centers were technically inefficient and so were using resources that they did not actually need.</p> <p>Conclusion</p> <p>The results broadly point to grave inefficiency in the health care delivery system of public health centers and that significant amounts of resources could be saved if measures were put in place to curb the waste.</p

The cost of health-related brain drain to the WHO African Region

The African Region continues to experience loss of a sizeable number of highly skilled health professionals (physicians, nurses, dentists and pharmacists) to Australia, North America and European Union. Past attempts to estimate cost of migration were limited to education cost only and did not include the lost returns from investment. The objective of this study was to estimate the social cost of emigration of doctors and nurses from the African Region to the developed countries. The cost information used in this study was obtained from one nonprofit primary and secondary school and one public university in Kenya. The cost estimates represent unsubsidized cost. The loss incurred by African countries through emigration is obtained by compounding the cost of educating a medical doctor and a nurse over the period between the age of emigration and the retirement age in recipient countries. The main findings were as follows: total cost of educating a single medical doctor from primary school to university is US$65,997; for every doctor that emigrates, a country loses about US$1,854,677 returns from investment; total cost of educating one nurse from primary school to college of health sciences is US$43,180; for every nurse that emigrates, a country loses about US$1,213,463 returns from investment. Developed countries continue to deprive African countries of billions of dollars worth of invaluable investments embodied in their human resources. If the current trend of poaching of scarce human resources for health (and other professionals) from African countries is not curtailed, the chances of achieving the Millennium Development Goals would remain dismal. Such continued plunder of investments embodied in human resources contributes to further underdevelopment of Africa and to keeping majority of her people in the vicious circle of poverty. Therefore, both developed and developing countries need to urgently develop and implement strategies for addressing this issue. African Journal of Health Sciences Vol. 13 (3-4) 2006: pp. 1-1

Impact of disaster-related mortality on gross domestic product in the WHO African Region

BACKGROUND: Disaster-related mortality is a growing public health concern in the African Region. These deaths are hypothesized to have a significantly negative effect on per capita gross domestic product (GDP). The objective of this study was to estimate the loss in GDP attributable to natural and technological disaster-related mortality in the WHO African Region. METHODS: The impact of disaster-related mortality on GDP was estimated using double-log econometric model and cross-sectional data on various Member States in the WHO African Region. The analysis was based on 45 of the 46 countries in the Region. The data was obtained from various UNDP and World Bank publications. RESULTS: The coefficients for capital (K), educational enrolment (EN), life expectancy (LE) and exports (X) had a positive sign; while imports (M) and disaster mortality (DS) were found to impact negatively on GDP. The above-mentioned explanatory variables were found to have a statistically significant effect on GDP at 5% level in a t-distribution test. Disaster mortality of a single person was found to reduce GDP by US$0.01828. CONCLUSIONS: We have demonstrated that disaster-related mortality has a significant negative effect on GDP. Thus, as policy-makers strive to increase GDP through capital investment, export promotion and increased educational enrolment, they should always keep in mind that investments made in the strengthening of national capacity to mitigate the effects of national disasters expeditiously and effectively will yield significant economic returns

The cost of health professionals' brain drain in Kenya

BACKGROUND: Past attempts to estimate the cost of migration were limited to education costs only and did not include the lost returns from investment. The objectives of this study were: (i) to estimate the financial cost of emigration of Kenyan doctors to the United Kingdom (UK) and the United States of America (USA); (ii) to estimate the financial cost of emigration of nurses to seven OECD countries (Canada, Denmark, Finland, Ireland, Portugal, UK, USA); and (iii) to describe other losses from brain drain. METHODS: The costs of primary, secondary, medical and nursing schools were estimated in 2005. The cost information used in this study was obtained from one non-profit primary and secondary school and one public university in Kenya. The cost estimates represent unsubsidized cost. The loss incurred by Kenya through emigration was obtained by compounding the cost of educating a medical doctor and a nurse over the period between the average age of emigration (30 years) and the age of retirement (62 years) in recipient countries. RESULTS: The total cost of educating a single medical doctor from primary school to university is US$65,997; and for every doctor who emigrates, a country loses about US$ 517,931 worth of returns from investment. The total cost of educating one nurse from primary school to college of health sciences is US$43,180; and for every nurse that emigrates, a country loses about US$ 338,868 worth of returns from investment. CONCLUSION: Developed countries continue to deprive Kenya of millions of dollars worth of investments embodied in her human resources for health. If the current trend of poaching of scarce human resources for health (and other professionals) from Kenya is not curtailed, the chances of achieving the Millennium Development Goals would remain bleak. Such continued plunder of investments embodied in human resources contributes to further underdevelopment of Kenya and to keeping a majority of her people in the vicious circle of ill-health and poverty. Therefore, both developed and developing countries need to urgently develop and implement strategies for addressing the health human resource crisis

Status of national health research systems in ten countries of the WHO African Region

BACKGROUND: The World Health Organization (WHO) Regional Committee for Africa, in 1998, passed a resolution (AFR/RC48/R4) which urged its Member States in the Region to develop national research policies and strategies and to build national health research capacities, particularly through resource allocation, training of senior officials, strengthening of research institutions and establishment of coordination mechanisms. The purpose of this study was to take stock of some aspects of national resources for health research in the countries of the Region; identify current constraints facing national health research systems; and propose the way forward. METHODS: A questionnaire was prepared and sent by pouch to all the 46 Member States in the WHO African Region through the WHO Country Representatives for facilitation and follow up. The health research focal person in each of the countries Ministry of Health (in consultation with other relevant health research bodies in the country) bore the responsibility for completing the questionnaire. The data were entered and analysed in Excel spreadsheet. RESULTS: The key findings were as follows: the response rate was 21.7% (10/46); three countries had a health research policy; one country reported that it had a law relating to health research; two countries had a strategic health research plan; three countries reported that they had a functional national health research system (NHRS); two countries confirmed the existence of a functional national health research management forum (NHRMF); six countries had a functional ethical review committee (ERC); five countries had a scientific review committee (SRC); five countries reported the existence of health institutions with institutional review committees (IRC); two countries had a health research programme; and three countries had a national health research institute (NHRI) and a faculty of health sciences in the national university that conducted health research. Four out of the ten countries reported that they had a budget line for health research in the Ministry of Health budget document. CONCLUSION: Governments of countries of the African Region, with the support of development partners, private sector and civil society, urgently need to improve the research policy environment by developing health research policies, strategic plans, legislations, programmes and rolling plans with the involvement of all stakeholders, e.g., relevant sectors, research organizations, communities, industry and donors. In a nutshell, development of high-performing national health research systems in the countries of the WHO African Region, though optional, is an imperative. It may be the only way of breaking free from the current vicious cycle of ill-health and poverty
