Comparison of Telemedicine versus In-Person Visit for Control of Asthma in Children aged 7-17years: A Randomized Controlled Trial.

Abstract

To compare asthma control between telemedicine and in-person visit in children aged 7 to 17 y. A non-inferiority randomized-controlled trial was conducted at a pediatric chest clinic, involving a total of 192 patients, with 96 children in each group of telemedicine and in-person follow-up. There was a significant improvement in the mean asthma control test (ACT)/ Childhood asthma control test (C-ACT) scores from baseline to three months in both groups, with no significant difference in the change of means between the two groups. The mean difference in ACT/C-ACT score at three months in the telemedicine and in-person visit group was -0.35; 95% CI (-1.30 to +0.10) [p-value 0.09]. There was a significant change in the mean Pediatric Quality of Life index (PQLI) scores from 57.2 ± 10.2 to 66.82 ± 7.99 in the telemedicine group and from 56.1 ± 11.7 to 66.71 ± 4.66 in the in-person visit group, however the mean difference in PQLI score in both the groups was not significant (p = 0.91). There was no significant difference in the number of asthma exacerbations (4 vs. 1) between telemedicine and in-person visit (p = 0.10). The mean telemedicine satisfaction questionnaire score in this study was 3.8 ± 0.7, which indicates that most of the parents were satisfied with the telemedicine follow-up process. This study revealed that telemedicine is non-inferior to in-person visit for follow-up of children with asthma and can be used as an alternative to in-person visit for the management of asthma, especially in remote settings and pandemic situations.
