ABSTRACT
The Undergraduate Nursing Course has been using videos for the past year or so. Videos are used for many different purposes such as during lessons, nurse refresher courses, reinforcement, and sharing and comparison of knowledge with the professional and scientific community. The purpose of this study was to estimate the efficacy of the video (moving an uncooperative patient from the supine to the lateral position) as an instrument to refresh and reinforce nursing techniques. A two-arm randomized controlled trial (RCT) design was chosen: both groups attended lessons in the classroom as well as in the laboratory; a month later while one group received written information as a refresher, the other group watched the video. Both groups were evaluated in a blinded fashion. A total of 223 students agreed to take part in the study. The difference observed between those who had seen the video and those who had read up on the technique turned out to be an average of 6.19 points in favour of the first (P < 0.05). The results of the RCT demonstrated that students who had seen the video were better able to apply the technique, resulting in a better performance. The video, therefore, represents an important tool to refresh and reinforce previous learning.
ABSTRACT
BACKGROUND: Anxiety levels have a considerable effect on patients during hospitalization. Cardiology Departments are characterized by a high turn-over of patients and it is necessary to give clear and exhaustive information routinely in compliance with legal and deontological requirements. AIMS: The aim of the study was to evaluate the effectiveness of an informative video, devised for patients undergoing coronarography, on reducing anxiety levels and getting more satisfaction from the received information. METHODS: A two arm RCT design was chosen. The patients in both study arms received standard care while the informative video was shown in the treatment group. The Spielberger scale was used to measure anxiety levels before the procedure while satisfaction as to the received information was measured using a scale with semantic indications. RESULTS: Ninety-three patients accepted to take part in the study. The weighted mean difference (WMD) between the anxiety levels of the treated and controlled groups was -8.24 (CI 95%: -12.04/-4.44; p<0.00001). The WMD of the level of satisfaction for the received information was +22.23 (CI 95%: +12.73/+31.73; p<0.00001). CONCLUSIONS: The use of the informative video in Cardiology Departments proves to be highly recommended as an instrument to lower anxiety levels and increase significantly the level of satisfaction deriving from the received information.
