Abstract Details


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


Vienna Institute for Research in Ocular Surgery, a Karl-Landsteiner-Institute, Hanusch Hospital, Vienna, Austria.


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 telephone one month post-operatively to reflect on their decision (decision regret scale).


Preliminary results based on 86 patients (40 study group, 46 control group) were analysed. The mean age was 69 (51-91) and 71 (52-93) years respectively. The duration of the face-to-face informed consent discussion was significantly shorter in the study group, 1 minute 58 seconds (IQR 64–163 sec) versus 2 minutes 23 seconds (104–274 sec; p=0.013). Patients in the study group answered significantly more questions correctly (score 16.5 versus 15.6 out of 19, p=0.014). A trend towards higher decisional confidence in the study group was found (p=0.082). Detailed final results including 50 additional patients will be presented.


Duration of the face-to-face consent process was significantly shorter in the study group and patients were better informed. Furthermore, there was a trend towards increased decisional confidence in the study group. These findings show that the interactive computer-based CatInfo tool is useful to improve the informed consent process.
