Reducing anxiety in preoperative patients: a systematic review.

There are still uncertainties regarding the appropriateness and effectiveness of various modes of delivering preoperative education. Hence, this systematic review was conducted to investigate the effectiveness of various preoperative educational interventions in reducing preoperative anxiety. Fourteen interventional trials (12 randomised controlled trials and two pre/post test trials) involving a total of 1752 participants were included in the review. Four studies used audiovisual; two trials used visual; two trials used multimedia-supported education; one trial used a website; two trials involved verbal education delivered by a psychologist or a nurse facilitator coupled with leaflets; and one trial involved informational leaflets only. Eight of the 14 trials demonstrated that preoperative education intervention reduced preoperative anxiety significantly (P<0.05). It can be concluded that preoperative education interventions are promising in reducing preoperative anxiety in patients scheduled for surgical procedures.
