The Impact of Clinical Trials Conducted by Research Networks in Pediatric Critical Care.

Objectives: Research networks in adult and neonatal critical care have demonstrated collaborative and successful execution of clinical trials. Such networks appear to have been relatively recently established in the field of pediatric critical care. The objective of this study was to evaluate the productivity and impact of randomized controlled trials conducted by pediatric critical care research networks, compared with nonnetwork trials. Data Sources, Study Selection, and Data Abstraction: We searched multiple online databases including MEDLINE, reference lists of randomized controlled trials, and relevant systematic reviews. Independent pairs of reviewers identified published randomized controlled trials administering any intervention to children in a PICU and abstracted data. A research network was defined as a formal consortium or collaborative research group established for the purpose of conducting clinical research. Data were independently abstracted in duplicate. Main Results: There were 288 pediatric critical care randomized controlled trials published in English between 1986 and July 2015, of which 15 randomized controlled trials (5.2%) were conducted by a total of five research networks. Network randomized controlled trials were more often multicentered, multinational, and larger in size (p
