Whittemore and Knafl's updated description of methodological approach for integrative review was published in 2005. Since then, the five stages of the approach have been regularly used as a basic conceptual structure of the integrative reviews conducted by nursing researchers. However, this methodological approach is seldom examined from the perspective of how systematically and rigorously the stages are implemented in the published integrative reviews.
