ObjectivesThe purpose of this study was to determine the concordance of the Broselow tape with the measured heights and weights of a community-based population of children, especially in light of the increase in obesity in today's children.MethodsThe authors examined more than 7,500 children in a cross-sectional, descriptive study in two different cohorts of children to compare their actual weight with their predicted weight by a color-coded tape measure.ResultsIn all patients, the percent agreement and kappa values of the Broselow color predicted by height versus the actual color by weight for the 2002A tape were 66.2% and 0.61, respectively. The concordance was best in infants, followed by school-age children, toddlers, and preschoolers (kappa = 0.66, 0.44, 0.39, and 0.39, respectively; percent agreement, 81.3%, 58.2%, 60.7%, and 64.0%, respectively). The tapes accurately predicted (within 10%) medication dosages for resuscitation in 55.3%-60.0% of the children. The number of children who were underdosed (by > or =10%) exceeded those who were overdosed (by > or =10%) by 2.5 to 4.4 times (p < 0.05). The tapes accurately predicted uncuffed endotracheal tube sizes when compared with age-based guidelines in 71% of the children, with undersizing (> or =0.5 mm) exceeding oversizing by threefold to fourfold (p < 0.05).ConclusionsThe Broselow tape color-coded system inaccurately predicted actual weight in one third of children. Caregivers need to take into consideration the accuracy of this device when estimating children's weight during the resuscitation of a child.
