Effect of Pre-Operative Video Assisted Teaching on Knowledge and Anxiety among the Patient Undergoing Abdominal Surgery

Abstract

The rate of post-operative complications is increasing with respect to increased demand of surgery, which may be related with less amount of knowledge and increased pre-operative anxiety. Pre-operative education of patients could improve the post-operative outcome. A pre experimental study was conducted with purpose to assess the effect of pre-operative video assisted teaching (VAT) on knowledge and anxiety among the patient undergoing abdominal surgery. For the study one group pre-test post-test design was adopted (n=60). A self-structured questionnaire was developed to assess the knowledge (r = 0.72) and standardized Hospital Anxiety Depression Scale tool used to assess the anxiety. The pre-test was conducted, then VAT was provided, followed by post-test on 8th day. There was great increase in knowledge score (mean difference=8.12) and decrease in anxiety (mean difference=9.79) and a negative correlation between knowledge and anxiety. A chi square association was performed with knowledge showing significant relationship with age, sex, previous hospitalization, previous abdominal surgery, duration of hospitalization, types of abdominal surgery and socio-economic status, but with anxiety showing significant relationship only with socio-economic status (p=0.005). The ANOVA test is performed which shows, no significant relationship of knowledge within selected  variable, age and disease condition,  and significant relationship within socio-economic status, similarly there is  no significant relationship of anxiety within age but significant relationship of anxiety within disease condition, and socio-economic status. These results suggest that pre-operative education is effective and should be incorporated into routine practice in reducing anxiety and improving knowledge among patients.
