But what’s health care got to do with software design?
Lots, explains Seebregts, a senior manager at the South African Medical Research Council, Executive Director of Jembi Health Systems, and a key player in a cluster of IDRC-funded projects on “e-health” in Africa.
More coherent health systems
Recently, there’s been a growing, worldwide realization that greater benefit could be wrung from poor countries’ limited health budgets by “shifting the focus away from isolated projects and toward strengthening health systems in general,” he says, addressing a workshop in Ottawa.
Computer specialists have a key role to play in achieving that. To improve the efficiency of health systems, managers and planners need sophisticated yet easy-to-use software programs allowing them to track both the demands on and the capacities of the health system, so they’ll be able to apply scarce resources where they’ll do the most good.
That’s where the IDRC-funded Open Architectures Standards and Information Systems (OASIS) project enters the picture. Operating in South Africa, Zimbabwe, Mozambique, and Rwanda, OASIS has provided support for African software designers to adapt open-source software to local conditions, to help those countries’ health authorities create and implement effective health policies.
The researchers — based at local universities — have faced several challenges. One is that the software must have maximum “interoperability”—meaning that it allows for communication between different aspects of the national health system and, ideally, across national borders. It must also be simple enough that local clinic staff feel comfortable using it.
Successes within challenging environments
Now entering its second phase, OASIS has already met with success.
The Mozambican arm of the project — dubbed M-OASIS — has been working closely with the national ministry of health. Recently M-OASIS entered into a longer-term working relationship to help incorporate e-health software into the ministry’s new five-year plan. In that country, M-OASIS has provided the government with reliable year-to-year statistics on deaths from HIV/AIDS, enabling the ministry to evaluate the effectiveness of its efforts to manage and treat the epidemic.
Another mark of success is that international funding agencies like the Rockefeller Foundation and the US Centre for Disease Control are now funding aspects of OASIS’ four-country program. Originally, IDRC was OASIS’ sole funder.
Comments Seebregts: “IDRC had a real catalytic role in this enterprise. It identified a new area of research, took the risks, and nursed it through the first phase until others saw the value of the work.”
How new technologies can help
As Africa embraces new information technologies supported by a rapidly growing robust fibre optic network across the continent, health systems — and the patients who rely on them — stand to benefit in various ways.
Medical records that are as mobile as patients, for example, can help clinic staff arrive at more accurate diagnoses. Meanwhile, electronic databases can help managers move the right drugs and supplies, in the right quantities, to the places they are needed.
Other e-health innovations bring multiple benefits. Cellphone users connected to computer servers can not only receive reminders about medication schedules or information about symptoms. They can also send word of sudden illnesses to authorities, giving officials an early warning that new epidemics may be brewing.
Cheaper, better patient care
Seebregts says even simple interventions can lead to enormous reductions in cost and improvements in treatment.
He cites the case of an HIV/AIDS patient whose antiretroviral drug regime appears to have stopped working. Though a clinician would normally opt to move the patient to second-line drug treatment, detailed electronic medical records and the use of laboratory tests and a clinical decision support tool” can indicate when the switch is not truly necessary.
“The moment you move to the second-line drugs, you’ve shortened a patient’s life expectancy by limiting drug options,” explains Seebregts. The second-line drugs are also several times more expensive than the standard treatment.
The Canadian connection
The e-health initiative has sparked collaboration across continents. For example, a new “living laboratory “ under construction at the University of KwaZulu-Natal in Durban, South Africa, will use software and models developed by Canada Health Infoway. But the benefits flow in two directions: lessons from the lab in Durban, in turn, will come back across the ocean to help Canada Health Infoway refine e-health models intended for use in Canada.
“We are in the midst of a wonderful process of mutual learning and growth,” comments IDRC program officer Chaitali Sinha.
Keeping it local
While international collaboration is important, Seebregts also insists that having the local capacity to keep systems up and running is key to making e-health work in Africa. That’s why he was happy when the team in Mozambique recently declined his offer to help them with a presentation.
“The greatest accolade for us,” he recalls, “was hearing ‘we don’t need you anymore–we’re a completely self-supporting unit.’”

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
