The Relationship of the Test for Respiratory and Asthma Control in Kids Initial Score on the Prognosis of Pre-school Children With Asthma: A Prospective Cohort Study

Abstract

Objective: The test for respiratory and asthma control in kids (TRACK) is currently the only standard follow-up tool for children under 5 years of age with asthma. The purpose of this study was to investigate the relationship between the TRACK initial score (Ti) and their prognosis after 6 months of follow-up in pre-schoolers with asthma.Design: A prospective cohort study.Methods: The study included pre-schoolers diagnosed with asthma at the Shanghai Children's Medical Center between January 2019 and June 2020, and follow-up for 6 months. TRACK scores, frequency of wheezing and respiratory infections, number of Emergency Department (ED) visits and treatment regimen were collected. According to the TRACK initial score, the children were divided into “Ti < 60 group” and “Ti ≥ 60 group,” and the two groups were compared in terms of TRACK score related indicators, clinical manifestations and treatment.Results: There are 102 pre-schoolers included in the analysis [78 boys (76.5%) and 24 girls (23.5%); mean (SD) age, 28.05 (11.63) months]. After 6 months of follow-up, the TRACK score was improved in both groups, and the “Ti ≥ 60 group” had a higher score, lower rate of uncontrolled asthma and fewer reassessments were required. There was no difference in the number of wheezing attacks between the two groups in terms of clinical presentation, but the “Ti < 60 group” had more respiratory infections and ED visits. Regarding the use of ICSs, in the “Ti < 60 groups,” the dose of ICSs was higher and reduced slowly, and the dose difference between the two groups began to appear after 5 months of follow-up.Conclusion: TRACK is essential for pre-schoolers with asthma at the time they are diagnosed. In addition, if the TRACK initial score is < 60, the probability of poor prognosis is higher.

Research on the intelligent internet nursing model based on the child respiratory and asthma control test scale for asthma management of preschool children

“…The nurses were advised to seek medical attention promptly if any discomfort was observed. The TRACK scale is an evaluation tool for the control of childhood asthma developed by the American scholar Murphy[ 7 ]. It is currently the only tool to evaluate the level of asthma control in children aged less than five years as well as the first evaluation tool that includes damage and risk.…”
