Original Article



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.


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.


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).


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.
