Cross-sectional survey of parental barriers to participation in pediatric participant research registries

Research registries are a powerful tool for boosting recruitment into clinical trials. However, little is known about how parents approach the decision to enroll their child in a pediatric participant research registry (PPRR). We conducted in-person, written, or telephone surveys with parents/guardians of children hospitalized at Children's Hospital of Omaha, Nebraska to identify attitudes towards and barriers to enrollment in PPRRs. Overall, our population (N = 36) had positive attitudes toward PPRRs, with 77.8% (CI: 61.6, 88.4) of participants stating they were "somewhat"or "very"likely to enroll their child. Likelihood to enroll differed between various recruitment and enrollment methods, with participants stating they would be more likely to enroll their child in a PPRR if they were recruited by their child's primary care provider or a nurse in clinic (p = 0.02) and less likely to enroll if they were recruited through social media (p<0.001). Additionally, over 90% of participants who were likely to enroll their child in a PPRR (N = 28) were also willing to provide demographic, medical, and lifestyle information. However, these participants remained concerned about inappropriate sharing of their information with insurance or for-profit companies (53.6%, CI: 35.8, 70.4) and about receiving unwanted telephone calls from the registry (78.6%, CI: 60.0, 90.0). Parents are generally willing to enroll their child in a PPRR. However, to optimize enrollment, investigators must understand parental preferences for and concerns surrounding enrollment in a PPRR.
