New Test for Respiratory and Asthma Control in pre-school Kids, aged 2-5 (TRACK) and "3S" Mnemonic

A validated questionnaire is needed to monitor respiratory control in preschool-aged children.

The Test for Respiratory and Asthma Control in Kids (TRACK) includes 5 items:

- frequency of respiratory symptoms (wheeze, cough, shortness of breath)
- activity limitation
- nighttime awakenings in the past 4 weeks
- rescue medication use in the past 3 months
- oral corticosteroid use in the previous year

Reliability was greater than 0.70. The control status was correctly classified in 81% and 78% of cases. Changes in TRACK scores of 10 or more points represent clinically meaningful changes in respiratory control status.

Compare TRACK (age 2-5 years) to C-ACT (age 4-11 years)

Test for respiratory and asthma control in kids (TRACK) is a caregiver-completed questionnaire for preschool-aged children. Childhood Asthma Control Test (C-ACT) is a mix between children and caregiver-completed questionnaire.

TRACK includes 5 questions. C-ACT includes 7 questions with a 1-4 scale (http://www.asthmacontrol.com/child.html).
