Plain English Summary

Background and study aims:
Being in hospital can increase stress levels for patients and we want to reduce the anxiety of patients who are undergoing surgery. Other studies, have looked into improving patients’ experience using information about the surgical treatment. This includes booklets and videos which have shown to reduce anxiety. Our aim was to investigate the effect of 2-D animation to provide information to patients undergoing bowel surgery, given to patients before surgery, on anxiety levels (before and after surgery. We also investigated if this improved patient knowledge retention.

Who can participate?
Patients, aged 18 and above who were due to undergo bowel surgery.

What does the study involve?
There were two groups of patients that were undergoing bowel surgery, one group watched a 13 minute cartoon video showing the steps of treatment in hospital from the time of admission to discharge and the other group did not. All were given the usual level of information and treatment. Anxiety score was obtained at different stages (at pre-assessment clinic, on the day of surgery, after surgery and before discharge) for both groups of patients. In addition a simple short questionnaire to assess patients’ knowledge about treatment (covered in information leaflet and in cartoon video) was given to both groups and an evaluation questionnaire to the patients who watched the video.

What are the possible benefits and risks of participating?
The possible benefit of the study is the development of a prototype to build upon in which patients and hospital staff can access a resource that will both inform them of the treatment of bowel surgery and help to reduce the level of anxiety. There are no known risks of associated with taking part in this trial.

Where is the study run from?
Queen Elizabeth Hospital, Adelaide, South Australia

When is the study starting and how long is it expected to run for?
The study started recruiting in August 2011 and finished recruiting patients in January 2012.
