The impact of psychological preparation for surgery on postoperative outcomes: a systematic review

Background: Psychological preparation has been demonstrated to improve post-operative outcomes including pain and health care resource use. This systematic review (registered with the Cochrane Anaesthesia Review Group) will investigate which methods of preparation are effective and for which outcomes. Economic data will be reviewed where available. Methods: Randomised controlled trials (RCTs) of adults undergoing elective surgery under general anaesthesia are included. Papers are identified using electronic searches, reference lists and contact with authors of studies to identify unpublished research. Expected results: In a meta-analysis including 38 RCTs, Johnston and Vogele (1993) found psychological preparation to be effective in improving various postoperative outcomes. It is expected that this up-dated review will provide further evidence about which techniques are effective because more studies are now available. Current stage of work: Papers are being screened for inclusion. Discussion: Identifying effective pre-surgical interventions may result in improved patient outcomes and healthcare resource use.
