Purpose:
Before performing a surgical procedure, informed consent (IC) is obtained. Parents may exhibit anxiety and/or a desire for more knowledge during the IC process for their child. The purpose of this study was to measure the impact of a multimedia intervention (MMI) versus conventional discussion on parental understanding and anxiety during the IC process for infants undergoing surgery for hypertrophic pyloric stenosis.
Methods:
A time-interrupted series design was employed over a 9-month period. In the first phase, conventional discussion for IC was performed. In the second phase, a MMI was utilized. In both phases, anxiety scores and post-consent knowledge tests were collected.
Results:
31 participants were included in the study, 17 in the conventional consent and 14 in the MMI phase. Parental anxiety around the IC discussion was measured. There was a significant decrease in anxiety noted with use of the MMI (p = 0.046) but no significant difference in knowledge (p = 0.84).
Conclusion:
The MMI significantly reduced parental anxiety during the IC process. Providers may consider applying this type of MMI to other surgical procedures. Securing IC in a manner that improves knowledge and decreases anxiety may improve long-term understanding and parental satisfaction with the health care process.
