Abstract Details


To assess whether informing patients with an interactive computer-based tool in addition to face-to-face discussion with their physician reduces face-to-face discussion time, increases the patient’s knowledge and influences the patient’s attitude towards surgery.

Patients with bilateral cataract scheduled for cataract surgery were randomly allocated to the study group or control group. Patients in the study group were given an interactive computer-based tool (CatInfo) containing a detailed audiovisual presentation about cataracts and its treatment. All patients had a face-to-face informed-consent discussion with a physician. Duration of the informed-consent discussion was measured. Afterwards, patients in both groups received the same validated questionnaire with cataract-related questions as well as questionnaires assessing the decisional conflict. Patients were interviewed via phone one month post-operatively to reflect on their decision (decision regret scale).


Preliminary results of 41 study group patients and 45 control group patients were analysed. The mean age was 69 years (51-91 years) and 71 years (52-93 years) respectively. The duration of the face-to-face informed consent interview was significantly shorter in the study group compared to the control group, 1 minute 58 seconds versus 2 minutes 23 seconds (IQR 63–177 versus 104–274 sec; p=0.014). Patients in the study group answered slightly more questions correctly than patients in the control group (16.3 versus 15.6 out of 19 points). This was not statistically significant (p=0.07). Detailed final results will be presented.


Duration of the face-to-face consent process was significantly shorter in the study group, nonetheless the patient’s knowledge was only slightly improved. These findings show that the interactive computer-based tool is a useful approach to document the informed consent procedure and to reduce face-to-face informed-consent discussion time without decreasing the patient’s knowledge.
