Abstract

The aim of this study was to assess the quality of reporting of nurse-driven randomized controlled trials involving a direct nutritional intervention. A bibliometric search for randomized controlled trials involving a direct nutritional intervention from 1991 to 2011 in nursing research was conducted. Both quality of the study and design aspects were evaluated. The prevalent randomized controlled trial design used is 2-arm parallel, individual, and randomized with a continuous primary endpoint. Global numbers of randomized controlled trials and the proportion of good-quality randomized controlled trials began a steady and marked rise, more than doubling, from the 1990s to about 2001 and increased slowly thereafter. Studies are overall sufficiently well designed, although there is still room for quality improvement. Additionally, implementation of new randomized controlled trial designs exists and should be advocated.
