Effectiveness of an Instructional Module on Knowledge and Anxiety of Caregivers of Children Undergoing Cardiac Catheterization – An Experimental Study

Abstract

Background: Diagnosis of cardiovascular disorders in children is a very stressful time for the entire family. During this period family caregivers are anxious about their child’s condition. At this time, nurses play an important role to educate the parents or caregivers about the child’s health, procedure that has to be performed, and pre- and post-operative care after procedure. This study was conducted to assess the effectiveness of an “instructional module” on knowledge and anxiety of caregivers of children undergoing cardiac catheterization. Materials and Methods: Caregivers of children with congenital heart disease were randomly enrolled in two groups with 30 caregivers in each control and experimental group. Preoperative knowledge and anxiety in both the groups were assessed by a self-structured questionnaire and the State-Trait Anxiety Inventory. An instructional module in the form of a booklet regarding cardiac catheterization was developed and administered to the experimental group while the control group received routine care instuctions. Caregivers’ postintervention knowledge was assessed by a structured knowledge questionnaire. Results: Median knowledge score was 2 (2–2) in the control group and 2 (1–2) in the experimental group among caregivers of the children during preintervention phase. The median anxiety score of the caregivers of children underwent cardiac catheterization during preintervention phase was 57.50 (47–61) in the control group and 53 (47.75–56) in the experimental group. The results revealed that there was a significant improvement in knowledge score regarding cardiac catheterization procedure and also there was reduction in the level of anxiety among caregivers in the postintervention experimental group (P < 0.001). Conclusion: The study suggests that the “instructional module” is effective in reducing the anxiety and improving the knowledge levels of caregivers regarding the preoperative and postoperative care of children who underwent cardiac catheterization.
