초록

Purpose: Informed consent is a basic standard of care for
all patients undergoing invasive procedures, but the effectiveness
of consent form describing risks of procedures in a
way that minimizes anxiety and maximizes recall of information
is often poor. This study was designed to compare
level of understanding and recall of information between
patients receiving visual aid assisted informed consent and
those administered written consent only.
Methods: A sample population was randomized into two
groups to receive one of two information delivery methods.
The intervention group was presented visual aids explaining
the procedure. The control group received information
from physicians with written consent in the traditional manner.
After the education sessions, all participants completed
a questionnaire including a 9-question knowledge measurement
section and were asked to grade there satisfaction
level on 4-point scale. Mean scores, agreement and satisfaction
levels were compared to assess whether the
informed consent with visual aids was superior to standard
written consent. Statistical analysis employed Student’s ttest,
and the chi-square test with significance levels at a pvalue
of <0.05.
Results: Of the 100 individuals enrolled, 50 were randomized
to the visual aids group. Mean knowledge scores were
higher in the visual aids group (76.4±11.1) than in the written
consent group (50.9±15.1, p=0.00), and the visual aid
group expressed greater satisfaction with their education
than did the written consent group (74.5±14.7 versus 49.0
±20.8, p=0.00). The proportion of agreement was also
higher in the visual aid group than in the written consent
group (p=0.00).
Conclusion: The use of visual aids in explaining central
venous catheterization yielded higher knowledge scores
and satisfaction levels than did traditional written informed
consent.
