Description: The purpose of this study was to determine the effectiveness of preadmission preoperative education for coronary artery bypass graft (CABG) patients. The sample consisted of 40 patients scheduled for an initial, elective CABG procedure. A randomized, experimental, posttest-only design was used. Subjects in the Experimental Group received both pre- and postadmission preoperative education; Control Group subjects received only postadmission preoperative education.

Preadmission preoperative education consisted of a 45 to 60 minute teaching session conducted by the investigator on a one-to-one basis with subjects 5 to 14 days prior to admission and a follow-up telephone call. Postadmission preoperative education consisted of routine preoperative teaching provided on a one-to-one basis by hospital personnel on the day before surgery. The outcome measures were: (a) preoperative knowledge of CABG surgery/routine, (b) postoperative state anxiety, (c) postoperative mood state, and (d) self-report of physiological recovery. Preoperative knowledge was measured by a CABG Surgery Knowledge Questionnaire (KQ), a 20-item multiple-choice test. The KQ was completed by Experimental Group subjects immediately after the preadmission teaching session and by Control Group subjects immediately after the routine postadmission teaching session. The S-Anxiety scale of the State-Trait Anxiety Inventory and the Profile of Mood States (POMS) were used to assess state anxiety and mood state, respectively, on postoperative day four. Physiological recovery was assessed with the Wolfer-Davis Recovery Inventory (RI) on postoperative days four, five, and six. Data analysis included independent t-tests and a 2 x 3 (group by day) repeated measures analysis of variance.

Subjects in the Experimental Group had significantly (a) higher KQ scores, (b) lower POMS scores (more positive mood states), and (c) higher RI scores (more favorable physiological recoveries). Although they also experienced less postoperative anxiety than subjects in the Control Group, this difference was not significant.

While preadmission preoperative education appears to be an effective strategy for increasing patients' knowledge of CABG surgery and enhancing the affective and physiological aspects of recovery, nurses must employ additional methods for helping patients cope with the extreme anxiety associated with CABG surgery.
