Patients unaware of risks and purpose of research even after informed consent

08.12.2006
As many as two-thirds of critically ill patients who consented to take part in a clinical trial do not remember the purpose and risks of the research shortly after.

A small study published today in the journal Critical Care, reveals that most Intensive Care Unit (ICU) patients who gave their informed consent to take part in a clinical trial remembered having participated in the trial ten days later. But two-thirds of the patients did not remember the purpose and risks of the trial, although they had been given information about them before the trial started.

Catherine Chenaud and colleagues from the University Hospital of Geneva, Switzerland, studied 44 ICU patients who had been selected for a clinical trial on inflammatory responses. The patients were given a 20-minute presentation about the study, its purpose and its risks and were given a leaflet to read, before agreeing to participate in the trial. They were then interviewed ten days later.

Chenaud et al.’ s results show that 35/44 patients remembered having taken part in the trial, but that only 20/44 patients remembered the purpose of the study and only 21/44 patients remembered the study risks. Furthermore, only 14/44 patients remembered both the purpose of the trial and its associated risks. The 14 patients who remembered all aspects of the trial did not differ from other patients, except that they had read the leaflet or had asked at least one question during the presentation, before signing the consent form.

The authors conclude that obtaining informed consent from patients should be a process which is revisited many times, rather than one event at the start of the trial, and that patients should be given information repeatedly during the course of a trial.

Im Focus: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
