Abstract Details

Purpose:

To evaluate whether the presentation of a video within the informed consent process (ICP) impacts on the knowledge about refractive excimer laser treatment (ELT), the satisfaction with the ICP, anxiety in respect to the ELT and the efficiency of the ICP.

Setting:

Eye Department Cantonal Hospital of Lucerne/Switzerland

Methods:

Single-center, randomized controlled trial. Consenting eligible patients were randomly assigned to a standard face-to-face consultation or to an additional video-assisted ICP. Knowledge, satisfaction with the ICP and anxiety regarding the ELT were assessed by a paper-based questionnaire. Differences between groups were tested with the Wilcoxon–Mann–Whitney, the Chi-square and Student’s-t tests.

Results:

We enrolled 58 patients in the non-interventional and 55 patients in the interventional groups. Mean age was 35.3 years (SD 9.6) and 51/113 (45.1%) were female. There was no difference between groups in terms of knowledge (22/25 points (interquartile range (IQR) 21-24) vs. 22/25 points (IQR 21-23); p=0.957), satisfaction with the ICP (“very satisfied”: 47/58 vs. 45/55; p= 0.915) and self-reported anxiety in respect to the ELT (median 8 (IQR 7-11) vs. median 9 (IQR 9-12); p=0.159). In the interventional group, the total ICP time was significantly lower (30.0 min (SD 1.6) vs. 25.0 min (SD 1.6); p= p= 0.032).

Conclusions:

Video-assisted ICP markedly reduced the total contact time while maintaining patients’ knowledge, satisfaction with the ICP and anxiety referring to the intervention on equal levels than the conventional face-to-face ICP. Video-assisted ICP could increase efficiency of clinical management on a double-digit percentage at equal running cost than conventional face-to-face ICP.
