Effect of written information of wound healing and self care practices in postoperative patients

Abstract

An experimental design was employed to determine the knowledge gained through use of written Wound Healing Fact Sheets. The study sample consisted of 30 postoperative patients recruited from the accessible population of abdominal and chest surgery patients. Subjects were randomly assigned to experimental and control groups. Experimental subjects were interviewed, received the Fact Sheets and underwent knowledge testing prior to discharge and by telephone approximately one week after discharge. Control subjects did not receive the Fact Sheets but were interviewed and tested identically to the experimental group. Low equivalent reliabilities were demonstrated through use of the KR-20 for the knowledge test. Content validity was established by a panel of three experts. A t-test computed between pre and post test mean scores identified a significant difference in knowledge gained by experimental versus control subjects. Low reliability weakens the significance of this result.
