Detection of changes of functioning over time after asthma exacerbation in children with the use of PROMIS domains

Patient reported outcome measures, such as the Patient Reported Outcomes Measurement Information System (PROMIS) may be utilized to understand experiences of patients. The purpose of this study was to determine the ability of PROMIS domains to detect changes in pain, physical functioning, and asthma impact over time for children experiencing asthma exacerbation.

Our prospective cohort study included children presenting to the emergency department (ED) for asthma exacerbation. Children completed PROMIS surveys in the ED, 7-10 days, and 1-3 months post-discharge. We used linear mixed models adjusted for age, gender, acute care utilization, and child global health to determine changes in PROMIS T-scores. We used self-reported child health response (Much better now versus a little better now or worse) at discharge as an anchor to determine if change in PROMIS scores corresponded with changes in health. A change was statistically significant if the 95% CI did not include 0.

Our study included 63 children who presented to the ED for acute asthma exacerbation. We identified that children improved significantly in all domains over time. There was improvement over time following discharge from ED for all pain and physical functioning domains, and asthma impact. Using the clinical anchor, those with considerable improvement in asthma symptoms had improved T scores from 4-17.

PROMIS domains of pain, physical functioning, depression, fatigue, peer relationships, and asthma impact are responsive to changes in health states over time. These domains may be used to measure clinically significant change in children experiencing asthma exacerbation.
