Scaling up HIV prevention programs is cost effective

12.07.2007
Scaling up HIV prevention programs can increase efficiency and thus prevent more HIV infections, according to a study published in the online open access journal BMC Health Services Research. Each doubling of a program’s scale can reduce costs by around a third, and some large programs are ten times more efficient than smaller ones - meaning that many more infections are averted for the same amount of resources.

“Proven prevention methods need to be scaled up rapidly,” says Elliot Marseille, the project director and lead author of the report. “Therefore, the fact that costs tend to go down as scale goes up is good news. This could save millions of lives, as well as keeping in check the number of new patients requiring expensive anti-retroviral therapies.”

Larger prevention programs use money more efficiently than smaller ones, analysis of the “Prevent AIDS: Network for Cost-Effectiveness Analysis” (PANCEA) project suggests. The study, funded by the US National Institutes of Health, seeks to improve HIV prevention funding allocation in low and middle-income countries.

Researchers at the University of California, San Francisco (UCSF) collaborated with local teams to collect recent cost and output data from 206 HIV prevention programs in India, Mexico, Russia, South Africa and Uganda. Six types of interventions were assessed including, voluntary counseling and prevention of mother-to-child transmission. And the team assessed relationship between scale (number of HIV prevention services provided) and unit cost (cost per unit of service).

The ‘scale up – cost down’ effect was seen across many countries and prevention approaches, with some large programs up to 100 times more cost effective than their smaller counterparts. But there is a threshold. When projects expand beyond a certain point, costs can start to rise – an effect noted in 2 types of HIV prevention interventions in India.

As more PANCEA-type data becomes available, researchers will be better able to predict these changes. “The global HIV prevention effort is rapidly increasing, with literally billions of dollars of spending anticipated in coming years.” says James G. Kahn, the project’s principal investigator. “We hope that research of this type will help programs better translate spending into HIV infections averted.”

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.

Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...

Im Focus: Room-temperature multiferroic thin films and their properties

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.

Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
