How Well Informed Are HIV Research Volunteers Giving ‘Informed Consent’?

03.08.2004


Pregnant women may be volunteering to participate in HIV research without fully understanding the benefits or consequences, according to a study published today in BMC Medicine. Volunteers’ comprehension of studies or treatments should be tested to ensure that their consent is truly informed and voluntary, say the study’s authors.

International regulations for ethical conduct of research require that volunteers are presented with detailed scientific and legal information before consenting to take part in a study. However, many funding agencies are unaware of the regulations, and there are no requirements for researchers to check volunteers’ understanding of this information.

The study’s authors, from Johns Hopkins University in Pune, India and Baltimore, USA found that use of visual aids significantly improved volunteers’ understanding of information relating to informed consent. They suggest that, “the current requirements of informed consent procedures are inadequate and that it should be a process that communicates information in an effective manner, allows for reiteration of information, and includes an evaluation of the patients’ knowledge prior to signing the informed consent document.”



Dr. Anita Shankar and her colleagues interviewed pregnant women who had just volunteered for an HIV study being carried out by scientists at an antenatal clinic in a hospital in Pune. Her team tested the patients’ knowledge of the study information that had been given to them during the informed consent process.

The researchers found that women’s understanding was frequently inadequate, particularly for difficult concepts such as the social risks associated with accepting HIV testing. Adequate understanding of the key subject areas was boosted from 38% to 72% by using simple visual aids during group education sessions. If the same visuals were used again during individual follow-up counselling sessions, the women’s level of understanding rose to 96%.

“This study demonstrates that complex constructs such as informed consent can be conveyed in populations with little education and within busy government hospital settings and that the standard model may not be sufficient to ensure true informed consent,” writes Shankar.

She continues: “As the visuals and this informed consent assessment tool are made available within India, it is hoped that they will be utilized by other government and non-governmental organizations throughout India to improve communication regarding HIV/AIDS.”

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
