The accuracy of emergency weight estimation systems in children—a systematic review and meta-analysis

The safe and effective administration of fluids and medications during the management of medical emergencies in children depends on an appropriately determined dose, based on body weight. Weight can often not be measured in these circumstances and a convenient, quick and accurate method of weight estimation is required. Most methods in current use are not accurate enough, but the newer length-based, habitus-modified (two-dimensional) systems have shown significantly higher accuracy. This meta-analysis evaluated the accuracy of weight estimation systems in children. Articles were screened for inclusion into two study arms: to determine an appropriate accuracy target for weight estimation systems; and to evaluate the accuracy of existing systems using standard meta-analysis techniques. There was no evidence found to support any specific goal of accuracy. Based on the findings of this study, a proposed minimum accuracy of 70% of estimations within 10% of actual weight (PW10 > 70%), and 95% within 20% of actual weight (PW20 > 95%) should be demonstrated by a weight estimation system before being considered to be accurate. In the meta-analysis, the two-dimensional systems performed best. The Mercy method (PW10 70.9%, PW20 95.3%), the PAWPER tape (PW10 78.0%, PW20 96.6%) and parental estimates (PW10 69.8%, PW20 87.1%) were the most accurate systems investigated, with the Broselow tape (PW10 55.6%, PW20 81.2%) achieving a lesser accuracy. Age-based estimates achieved a very low accuracy. Age- and length-based systems had a substantial difference in over- and underestimation of weight in high-income and low- and middle-income populations. A benchmark for minimum accuracy is recommended for weight estimation studies and a PW10 > 70% with PW20 > 95% is suggested. The Mercy method, the PAWPER tape and parental estimates were the most accurate weight estimation systems followed by length-based and age-based systems. The use of age-based formulas should be abandoned because of their poor accuracy.Electronic supplementary materialThe online version of this article (10.1186/s12245-017-0156-5) contains supplementary material, which is available to authorized users.

“…11 To date, there was no literature published on the validation of PAWPER weight estimation systems among the Southeast Asian population. With the conflicting results of the use in extremes of weight and limitation in the study population, [1][2][3][4][5][6][7][8][9][10] it is relevant to further determine the accuracy and precision of these pediatric emergency tapes. This study is the first to use both the Broselow and PAWPER weight estimation methods among Filipino children.…”

“…In pediatric emergencies, determination of body weight is essential in the management of a critically unwell child. [1][2][3] During a high-stress and time-limited environment, it has been a challenge for emergency physicians to determine the child's actual body weight by obtaining it from calibrated scales. 1,3,4 Overestimation or underestimation of a child's weight may result in ineffective care by under-or overdosing medications leading to related morbidity or mortality.…”
