Barriers to enrollment in a randomized controlled trial of hydrocortisone for cardiovascular insufficiency in term and late preterm newborn infants.

OBJECTIVE: To analyze reasons for low enrollment in a randomized controlled trial (RCT) of the effect of hydrocortisone for cardiovascular insufficiency on survival without neurodevelopmental impairment (NDI) in term/late preterm newborns. STUDY DESIGN: The original study was a multicenter RCT. Eligibility: ⩾34 weeks' gestation, <72 h old, mechanically ventilated, receiving inotrope. Primary outcome was NDI at 2 years; infants with diagnoses at high risk for NDI were excluded. This paper presents an analysis of reasons for low patient enrollment. RESULTS: Two hundred and fifty-seven of the 932 otherwise eligible infants received inotropes; however, 207 (81%) had exclusionary diagnoses. Only 12 infants were randomized over 10 months; therefore, the study was terminated. Contributing factors included few eligible infants after exclusions, open-label steroid therapy and a narrow enrollment window. CONCLUSION: Despite an observational study to estimate the population, very few infants were enrolled. Successful RCTs of emergent therapy may require fewer exclusions, a short-term primary outcome, waiver of consent and/or other alternatives.

Didactic components of a comprehensive pediatric competency program.

The infusion nurse specialist working with pediatric patients must demonstrate competencies related to all stages of child growth and development. In addition, specific skills requiring competency validation in the pediatric practice setting include calculation of pediatric dosages, maintaining fluid balance, use of specific devices, age-specific skills, and management of complications. This article presents a discussion of each of these areas as well as recommendations for methods of competency validation.
