Educational materials aimed at improving people's ability to understand information about risk are scarce.
In 2 trials, adults with high or low socioeconomic status (SES) were randomly assigned to receive a primer about understanding risk or a general health booklet. In both SES groups, adults receiving the primer more often passed a medical data interpretation test than did those receiving the general health booklet. They also expressed greater interest in medical statistics but not greater confidence in interpreting statistics, and most rated the primer helpful or very helpful.
The authors did not examine whether improved data interpretation skills affected decision-making.
SES = socioeconomic status; VA = Veterans Affairs.

Dear Sirs: In 2004 we conduct a study on Informed Consent Process in gynecologic area. The informational step was conducted collectively and consent was individually obtained. The principal investigator give an oral presentation using tables, maps, and other elucidative figures to allow better understanding. All potential participants are allowed to ask questions orally or in a written instrument. After that, the Consent form was shown. A new round of questions was taken. Forty-five patients were interviewed, immediately after the consent obtainment. Remembrance capacity of information about procedures, risks and benefits explained were verified. All participants (100%) remembered the procedures, 54% the risks and 96% the probable benefits. Comparing these data with others from a similar study using conventional informed consent process (individual information transmission) the subjects remember more information in the present study. In early studies only 47,5% remembered procedures, 47,5% benefits and 22,0% risks. These results show that informing collectively the research subjects when getting the Informed Consent increment understanding. Reference: Goldim JR, Pithan CF , Oliveira JG , Raymundo MM.
