A randomized prospective study on anxiety reduction by preparatory disclosure with and without video film show about...

Unfortunately, giving preparatory information to the patient is generally regarded as legally mandatory for obtaining his written consent to an invasive procedure. Disclosure, however, could be used to reduce his anxiety as well; we hypothesized that showing a preparatory video film might be helpful in this respect. Patients who were admitted for elective coronary angiography were eligible for the study. 65 were randomized to two groups: both groups received the same leaflet and personal interview with the doctor, but only one group (Group 2) additionally watched a 14 min preparatory video. Anxiety was assessed with the State-Trait Anxiety Inventory (STAI). The two groups did not differ with respect to initial anxiety levels and other important parameters. Group 1 patients, who did not watch the video had no significant reduction in anxiety score; group 2 patients showed a significant benefit. We conclude that disclosure with the additional aid of a video film may be an easy, yet effective way to reduce patients' anxiety.
