• 1 other identifier: TABED 2-25-1755

Brief Summary

This randomized comparative trial evaluated whether an animated educational video, added to standard verbal counselling, differs from a content-matched written information leaflet, also added to standard verbal counselling, in improving procedural knowledge and reducing preoperative anxiety among adult kidney transplant candidates and prospective living donors. Participants were assessed immediately before and immediately after the assigned intervention. Secondary outcomes included participant satisfaction, preferred information modality, and the understandability and actionability of the educational materials.

Conditions

Kidney Transplantation (Status Post); Preoperative Anxiety; Patient Education

Keywords

patient education; animated video; informed consent; preoperative anxiety; APAIS; kidney transplantation; living donor

Outcome Measures

Primary Outcomes (2)

• Change in procedural knowledge

  Procedural knowledge was measured with a 7-item investigator-developed multiple-choice Kidney Transplant Surgical Process Knowledge Questionnaire, scored as the number of incorrect responses. Scores range from a minimum of 0 to a maximum of 7. Higher scores indicate worse knowledge (more incorrect answers); a decrease from pre- to post-test indicates a better outcome.

  Day 1 (immediately before and immediately after the intervention, same study visit)

• Change in preoperative anxiety with the Amsterdam Preoperative Anxiety and Information Scale (APAIS) score

  Preoperative anxiety and information need were measured with the Amsterdam Preoperative Anxiety and Information Scale (APAIS), total score. Scores range from a minimum of 6 to a maximum of 30. Higher scores indicate a worse outcome (greater anxiety and information need); a decrease from pre- to post-test indicates a better outcome.

  Day 1 (immediately before and immediately after the intervention, same study visit)

Secondary Outcomes (5)

• Post-intervention knowledge score (between groups)

  Day 1 (immediately after the intervention, same study visit)

• Post-intervention Amsterdam Preoperative Anxiety and Information Scale (APAIS) score (between groups)

  Day 1 (immediately after the intervention, same study visit)

• Participant satisfaction

  Day 1 (immediately after the intervention, same study visit)

• Preferred information modality

  Day 1 (immediately after interventions and cross-over exposure to both formats, same study visit)

• Understandability of the educational materials, assessed with the Patient Education Materials Assessment Tool (PEMAT) score

  Baseline (educational materials assessed prior to participant enrollment)
