Considering the prevalence of low- or middle-income countries and increasing obesity in Latin America, the utility of the BT remains unclear in this region. Despite widespread assessment of the BT, there has been only one study on the BT in Latin American and none in Peru. ![]() This difference may be due to the variation in obesity rates, given that the BT was derived from United States pediatric data. A recent systematic review reported that the BT tends to underestimate weight in high-income countries while overestimating in low- and middle-income countries. Assessment of the BT’s accuracy internationally has yielded mixed results. This length translates to a weight estimation and color-coded zone that lists appropriate weight-based drug dosages, volumes, and equipment sizes.Īs emergency medicine has grown globally, the utility of the BT has been tested in international populations with the hope of improving pediatric resuscitation. The BT requires a provider to position the tape beside the patient and measure them from head to heel. ![]() One of the most widely used methods is the Broselow tape, which was developed in the United States based on data from the National Health and Nutrition Examination Survey. In order to alleviate some of this burden, numerous weight estimation methods have been developed. These factors, coupled with a complex calculation, could explain why pediatric medication dosing errors occur in emergency settings. During a pediatric emergency, weighing a child is often not feasible due to a lack of equipment and the condition of the patient. Underestimation of weight may lead to the use of non-therapeutic medication doses or incorrect equipment sizes and, subsequently, ineffective resuscitation.Īccurate weight estimation is a critical first step in the process of calculating a safe and effective medication dose for children. The BT underestimates the actual weight of Peruvian pediatric patients in all color categories, particularly in children with higher body mass indexes. In terms of accuracy, the overall error within 10% was 62.8%. The overall percent difference was -7.84% with differences gradually increasing for weights over 10 kg. Likewise, the Bland-Altman plot of agreement between estimated and measured weights shows an overall underestimation, or bias, equal to 1.60 kg. Accuracy was estimated by statistical comparison of mean absolute percent differences, error within 10% (EW10), and color zone agreement.Ĭomparison of mean differences between measured weight (MW) and estimated BT weight shows that the BT underestimates actual weight for all color zones in this population. Patient height and weight were measured and compared with the weight and color zone generated by the 2017 edition of the BT. This was a retrospective cross-sectional study of 1,160 children aged two to 19 years from three outpatient clinics in La Libertad, Lima, and Iquitos, Peru. ![]() The primary objective of the study was to assess the accuracy of the BT in a Peruvian pediatric population. Many accuracy studies have been performed for various countries and regions of the world but there is very little information for Latin American countries. The Broselow tape (BT) is a useful pediatric tool for weight estimation and dosing reference during emergency care.
