Validation of the Korean Pediatric Emergency Tape with Two National Anthropometric Surveys in Korean Children

Background: The Korean Pediatric Emergency Tape (KPET), developed using 2005 anthropometric data, aims to improve weight estimation in Korean children. However, its validity has not been evaluated using recent large-scale data. This study evaluates the accuracy of the KPET compared with the latest version of the Broselow Tape (BT) using contemporary national anthropometric datasets. Methods: A cross-sectional analysis was conducted using pooled data from the 2019 National Health Screening Program for Infants and Children (NHSPIC, age 0-5) and the 2018-2019 Student Health Examination Sample Survey in Korea (SHESS, age 6-12). Accuracy was assessed by the proportion of estimates within 10% (PW10) and 20% (PW20) of measured weight, and by concordance between estimated and measured weight color zones. Results: Data from 1,992,646 (KPET) and 1,987,504 (BT) children were analyzed. In NHSPIC, the KPET showed slightly lower overall accuracy than the BT (PW10: 72.7% vs. 74.0%) but outperformed the BT in infants (PW10: 72.1% vs. 67.4%). In SHESS, the KPET consistently underperformed compared with the BT (PW10: 49.5% vs. 52.9%). The KPET showed higher concordance only in infants. Both tapes showed a trend of underestimation with increasing age, more pronounced in the KPET. Conclusion: The KPET showed lower overall performance than the BT but outperformed the BT in infants. Its accuracy declines in older children and tends to underestimate weight. Regular updates using recent anthropometric data are necessary to ensure accurate weight estimation and reflect current growth trends in Korean children.
