Validation of a Smart Phone App to Non-invasively Measure the Size of Children

Not Applicable

Completed

• Conditions: Growth and Development
• Interventions: Device: Size Measurement by a Smart phone App

• Registration Number: NCT02805192
• Lead Sponsor: University of Zurich

Brief Summary

Smart phones are omnipresent. Apps exist to calculate size of medical equipment and doses of medication if a valid weight or age is entered. During emergency situations, these values are often unknown. An App has been developed to measure the size of a child noninvasively. This App is now to be validated in clinical practice. App measured size is calculated and compared to the real size of a child. Via known percentiles of age/weight of the child is calculated upon the App measured size. This value is compared to the mother's, physician's and nurses estimation of the size and weight.

Depending on the size multiple algorithms exist to estimate weight, age and medical values. ("Kindersicher ®", "Notfalllineal ®" and "Broselow Tape ®"). These estimations by the calculations will also be compared to actual weight and age.

Children from 0-12 years of age are included in the emergency Department of the Children's Hospital of the University of Zurich after informed consent obtained by the parents. No therapy decisions from these calculations will be made. The therapy is independent of this study.
