While the PAWPER system still proved to be more accurate than other weight estimation systems in these studies, some limitations of the tape were identified. The need for a modification of the original PAWPER system became apparent from the results of local and international research. The most accurate weight-estimation systems available should therefore be used, and the continued use of weight estimation methods that are known to be inaccurate should be considered to be poor medical practice. Although some drugs (such as opioids) can be titrated to effect, some drugs (such as anticonvulsants) require an accurate first-time administration to ensure optimum outcomes. The effectiveness and safety of treatment is ultimately dependent on the accuracy of weight estimation, as enough drug must be administered to ensure efficacy but not too much to cause toxic or unwanted side effects. Obtaining an estimate of weight forms part of the emergency management of critically ill or injured children, as most drug doses, and many other interventions, are based on weight. Total body weight-TBW Ideal body weight-IBW Emergency Department-ED Introduction PAWPER XL tape, medical emergencies, emergency department, body weight, fat-free mass Abbreviations The increased length and number of habitus score categories of the PAWPER XL tape enabled it to outperform the PAWPER tape in children >153cm in length and in severely obese children. For IBW the PW10 for the PAWPER XL tape, the PAWPER tape and the Broselow tape was 87.9%, 86.7% and 80.0% respectively.Ĭonclusions: The PAWPER XL tape estimated both TBW and IBW extremely accurately, significantly better than the other weight estimation systems.
Results: The percentage of TBW estimates within 10% of actual weight (PW10) for the PAWPER XL tape, the PAWPER tape, the Mercy method and the Broselow tape was 83.4%, 81.8%, 63.9% and 57.1% respectively. These predicted weights were compared to actual weight and calculated IBW. Methods: Estimations of TBW and IBW were obtained using the Broselow tape, the Mercy method, the original PAWPER tape and the new PAWPER XL tape in a convenience sample of 332 Emergency Department children. The aim of this study was to evaluate the accuracy of the PAWPER XL tape in estimating total body weight (TBW) and ideal body weight (IBW) in a population with a high prevalence of underweight and obese children. The PAWPER tape was redeveloped as the PAWPER XL tape, to provide additional capacity for estimating weight in obese children and taller children (for extra-length and extra-large children). In addition, adjustment of 1 color-coded zone may be considered in children with extreme weight.Background: The PAWPER tape has proved to be one of the most accurate weight estimation systems available, but its reduced accuracy in obese children and relative shortness (153cm) limit its functioning. Conclusion BT accurately estimates weight in approximately two-thirds of Korean children. Differences of no more than 1 color-coded zone between estimated and measured weights accounted for 89.8% and 84.1% of the under- and overweight (or obese) children, respectively. The accuracy and concordance of BT were 64.4% and 67.2%, respectively. The bias was –5.4% (P < 0.001), and the limits of agreement were –28.3% and 17.6%, respectively. Results A total of 108,128 children were enrolled. The accuracy and concordance were further assessed according to the age groups and body mass index-for-age Z-score ( 2, overweight or obese). We measured the accuracy of BT, defined as within a 10% error of the measured weight, and the concordance of the color-coded zones derived from the estimated and measured weights. The weights estimated by BT were compared with measured weights of the children using Bland-Altman analysis with results recorded as percentage differences. Methods From the population used for the survey, we sampled children aged 0-12 years. The authors aimed to validate BT using the 2005 Korean nationwide anthropometric survey data. The validation was previously performed in a small-scale dataset. Validation of BT in Korean children is essential because the tool was developed based on children’s weight and height in the United States. Abstract Purpose In Korea, the Broselow tape (BT) is widely used to estimate weight in resuscitation.
