Are "virtual" paediatric weight estimation studies valid?

摘要: Abstract Introduction “Virtual” studies account for nearly one-third of all published weight estimation articles, but the validity these virtual has never been evaluated. It is important to establish this in order decide whether results can be applied real-world usage. The objectives study were evaluate accuracy estimates using Broselow and PAWPER tapes compare actual real-life from tapes. Methods Virtual weights generated anthropometric data a sample 1385 children whom tape available. was compared against each child’s weight. agreement real also Results percentage within 10% 57.9% 59.3% respectively 76.6% 78.4% respectively. Cohen’s kappa 0.65 0.64 respectively, which indicated substantial agreement. Conclusions had very similar outcomes both study. However, if are used, they should followed by assess impact human patient factor errors on systems.
