This article argues that mobile phone connectivity in developing countries facilitates social and economic development through increased access to people, information and services such as health care, education, employment opportunities and market information. In developing countries, which lack the physical and technical infrastructure present in more developed nations, cell phone surveys provide an inexpensive and feasible way to conduct population-based data collection. However, the authors point out several issues that should be considered when conducting cell phone surveys in developing countries. Reception may not be available in rural zones, and it may be difficult to sample owners from cell phone registration lists if most users are unregistered. In addition, one needs to be aware of the cost that cell phone subscribers pay to receive a call and offer reimbursement for the time spent responding to the survey. Selection of one adult respondent from a sample household should always include consideration of the number of adults with cell phones in the household and whether people share cell phones. Text messages rather than voice calls may also be the primary means of cell phone communication in developing countries. The authors conclude that cell phone health surveys may come into wider use if the above issues can be addressed.
Monitoring equity and research policy
This paper was commissioned as a background discussion paper for the Global Symposium on Health Systems Research, held in Switzerland from 16-19 November 2010. It discusses how best to enhance capacity for health systems research (HSR), with a particular focus on low- and middle-income countries (LMICs). A systematic review was conducted of initiatives and interventions that have sought to enhance capacity for health systems research. The review sought to identify and include all papers that described a capacity development initiative for health systems or health services research. Out of 73 articles identified, 24 papers were concerned with LMICs. The articles found in the review focused primarily on the individual and organisational levels and paid less attention to the broader environment such as national research funding systems and their links to HSR. This may be because many of the papers were from high-income countries, where the challenges faced are somewhat different in nature to LMICs. Given the very weak evidence found through the systematic review, the recommendations build upon the findings from the review, but also draw upon the experience of the authors, to identify promising avenues for capacity development in the future.
A new platform for scaling up drugs and other health interventions to meet national and regional needs in developing countries was launched at the opening of the First Global Symposium on Health Systems Research, held from 16-19 November 2010 in Switzerland. The platform is a new collaboration of several organisations at the World Health Organization, with funding from the Norwegian Agency for Development Co-operation (NORAD) and the Swedish International Development Co-operation Agency (SIDA). The first seven projects were announced, which include projects in Kenya and Uganda. The platform is guided by an open, transparent selection of proposals and has been set up to help build evidence for the health-related Millennium Development Goals to improve child and maternal health and reduce HIV/AIDS, and to build capacity for health systems research and knowledge translation, particularly in low- and middle-income countries. The platform is intended to allow a greater degree of ‘inter-disciplinarity’ to strengthen the whole health system. It will examine the interface between scale-up and implementation of health services.
India and South Africa will launch a joint research project to find vaccines for HIV strains common to both countries. The project was formally approved by the governments of both countries last spring and is expected to be launched by the end of 2010. Virander Chauhan, director of the International Centre for Genetic Engineering and Biotechnology, New Delhi, said that the five-year, US$1 million dollar project will involve around five research groups from each country with core competence in basic and HIV vaccine research. A successful partnership could serve as a model for similar South–South collaborations and inspire other developing countries to go the same route.
Infectious diseases are bound by a complex interplay of factors related as much to the individual as to the physical, social, cultural, political and economic environments. Furthermore each of these factors is in a dynamic state of change, evolving over time as they interact with each other. Simple solutions to infectious diseases are therefore rarely sustainable solutions, this article argues. This calls for interdisciplinary approaches that address complexity. The article proposes that research and the largely biomedical interventions for neglected tropical diseases, largely neglect the social and ecological contexts that lead to the persistence of these diseases.
This background paper was prepared for the Global Symposium on Health Systems Research, held from 16-19 November 2010 in Switzerland, and it is concerned with how best to enhance capacity for health systems research (HSR), with a particular focus on low- and middle-income countries (LMICs). A systematic review was conducted of initiatives and interventions that have sought to enhance capacity for health systems research, and 73 research papers were included - 49 papers from high-income countries (HICs) and 24 from low- and middle-income countries. The review found that capacity building initiatives focused primarily on the individual and organisational levels and paid less attention to the broader environment, such as national research funding systems and their links to HSR. Governments, donors and non-governmental organisations are urged to invest in co-ordinated efforts to develop additional capacity for health systems research, partly by re-directing funding that currently goes to short-term technical assistance towards longer-term institutional support.
This study aimed to determine whether routine surveys, such as the Demographic and Health Surveys (DHS), have underestimated child mortality in Malawi. Rates and causes of child mortality were obtained from a continuous-registration demographic surveillance system (DSS) in Malawi for a population of 32,000. Between August 2002 and February 2006, 38,617 person-years of observation were recorded for 20,388 children aged < 15 years. There were 342 deaths. Re-census data, follow-up visits at 12 months of age and the ratio of stillbirths to neonatal deaths suggested that death registration by the DSS was nearly complete. Infant mortality was 52.7 per 1000 live births, under-5 mortality was 84.8 per 1000 and under-15 mortality was 99.1 per 1000. One-fifth of deaths by age 15 were attributable to HIV infection. Child mortality rates estimated with the DSS were approximately 30% lower than those from national estimates as determined by routine surveys. The fact that child mortality rates based on the DSS were relatively low in the study population is encouraging and suggests that the low mortality rates estimated nationally are an accurate reflection of decreasing rates.
In countries with generalized epidemics of human immunodeficiency virus (HIV) infection, standard statistics based on fertility history may misrepresent progress towards this target owing to the correlation between deaths among mothers and early childhood deaths from acquired immunodeficiency syndrome. To empirically estimate this bias, this study collected child mortality data and fertility history, including births to deceased women, through prospective household surveys in eastern Zimbabwe during 1998–2005. According to the empirical data, standard cross-sectional survey statistics underestimated true infant and under-5 mortality by 6.7% and 9.8%, respectively. These estimates were in agreement with the output from the model, in which the bias varied according to the magnitude and stage of the epidemic of HIV infection and background mortality rates. The bias was greater the longer the period elapsed before the survey and in later stages of the epidemic. Bias could substantially distort the measured effect of interventions to reduce non-HIV-related mortality and of programmes to prevent mother-to-child transmission, especially when trends are based on data from a single survey. A mathematical model with a user-friendly interface is available to correct for this bias when measuring progress towards Millennium Development Goal 4 in countries with generalised epidemics of HIV infection.
The Millennium Declaration, adopted by the United Nations in 2000, set a series of Millennium Development Goals (MDGs) as priorities for UN member countries, committing governments to realising eight major MDGs and 18 associated targets by 2015. Progress towards these goals is being assessed by tracking a series of 48 technical indicators that have since been unanimously adopted by experts. This concept paper outlines the role member Health and Demographic Surveillance Systems (HDSSs) of the INDEPTH Network could play in monitoring progress towards achieving the MDGs. The unique qualities of the data generated by HDSSs lie in the fact that they provide an opportunity to measure or evaluate interventions longitudinally, through the long-term follow-up of defined populations.
Couples should be included in HIV prevention research, but their recruitment in southern Africa is challenging given high levels of migration and non-cohabitation, according to the authors of this pilot study. The study describes the recruitment strategies and experiences in rural South Africa when conducting HIV research. With the aim of recruiting 20 couples at mobile voluntary counselling and testing (VCT) caravans and community venues, 75 index partners were screened with an average of four additional contacts required to schedule interviews. The study found that, despite the care taken to maximise recruitment, recruiting just 20 couples required a substantial investment of time and resources, so recruiting and interviewing couples is a feasible option, but requires substantial resources. Given the need to identify effective HIV behavioural interventions in South Africa, the authors believe that couples-focused studies and interventions can be one possible component in efforts to promote testing and reduce HIV transmission.
