Innovations in education:A prospective study of storytelling narratives to enhance hepatitis C virus knowledge among substance users

BACKGROUND Even though substance users have the highest hepatitis C virus(HCV)burden,many lack knowledge about the infection.Lack of knowledge is an important obstacle to pursuing HCV care.Although printed materials are conventionally utilized to disseminate HCV-related knowledge,narrative story-telling videos may be an alternative.Data are extremely limited,however,in the ability of storytelling videos to increase HCV knowledge among substance users.In this study,we hypothesized that a story-telling narrative video would increase substance user’s immediate and 1-month HCV-related knowledge compared to a printed format.AIM To assess immediate and 1-month HCV-related knowledge retention among substance users comparing education delivered via a storytelling narrative video compared to a printed format.METHODS We conducted a prospective matched,case-control study among substance users actively prescribed buprenorphine enrolled from two sites.The intervention site received the video and the control site,the brochure.Participants(n=176)were matched on age,gender,and race.We obtained extensive patient and stakeholder input on the video’s design,validated the video’s content,and developed a recruitment plan to guide participant enrollment.Knowledge was assessed by administration of a 25-item instrument immediately before,immediately after,or one month after the intervention.Data were analyzed using nonparametric and generalized linear mixed-effects models.RESULTS We recruited a total of 176 substance users,90 and 86 individuals,from each site,respectively.One-month follow up occurred in 92%and 94%of enrollees in the control and intervention groups,respectively.In comparison with the pre-intervention scores,immediate knowledge recall increased significantly for both the intervention(P<0.0001)and control(P<0.0001)groups.Multivariate modeling revealed a significant improvement in HCV-related knowledge and retention(P=0.033)among participants who viewed the storytelling video.CONCLUSION Storytelling narratives emphasizing HCV education appear to be an effective method to increase HCV-related knowledge among substance users.They should become an educational cornerstone to promote HCV management among this population.
