Use of Mobile Devices and the Internet to Streamline an Asthma Clinical Trial

The Research Participant Assessment Score (RPA Comprehension) was a 17-item questionnaire designed to assess comprehension of study information at screening (Visit 1, week -8) between MICT and LASST trial designs. The same 17-item questionnaire was administered to the adolescent participant and to the caregiver participant. The items were scored as 1=incorrect, 2=partially correct, 3=correct (minimum possible score=17 and maximum possible score=51). Scores were assigned by two trained coders who independently listed to audio recordings of the RPA Comprehension questionnaire administration. Scores from the two coders were averaged for a final score. Higher scores indicate better comprehension. Mean (95% Confidence Interval) are the outcome measure reported.

The Asthma Control Test is a 5-item Likert scale questionnaire; Scaling of items 5-point scale (for symptoms and activities: 1=all the time to 5= not at all; for asthma control rating: 1=not controlled at all to 5=completely controlled); The score for each item is summed to generate a total score. The scores range from 5 (poor control of asthma) to 25 (complete control of asthma), with higher scores reflecting greater asthma control. An ACT score >19 indicates well-controlled asthma.

The study was powered to have greater than 90% power to detect a clinically meaningful difference of 3 in the ACT score between the MICT Trial Design and the LASST trial Design , assuming a mean score of 19 with a standard deviation of 4 (data from a previous ALA-ACRC trial).

Spirometry grade scores in MICT participants (who performed spirometry at home) were compared with spirometry grade scores in LASST participants (who performed spirometry at the study sites). Spirometry grade scores were only available for LASST participants at Visit 3 (week 0), therefore only spirometry grade scores from Visit 3 were compared between MICT and LASST participants. Per the LASST trial no scoring was performed on the LASST participants for any other visit; the scoring for the LASST trial was for quality control only and was not a pre-specified trial outcome.

Spirometry grade score scale was: 4.00 (highest=best possible score), 3.00, 2.00, 1.00, 0.00 (lowest=worst possible score). The maximum score was 4.00, the minimum score was 0.00. Higher scores indicate better spirometry score and therefore better quality.

This outcome was to measure differences in timeliness and completeness of forms completed at home through REDCap in MICT participants compared with LASST participants.

No data were collected for this outcome. This is because in designing the REDCap database used to send questionnaires to the MICT trial participants and to store the responses from the completed questionnaires, data checks were put into place to prevent incomplete forms. We did this by requiring all fields to be completed before the questionnaire could be submitted. If a questionnaire was not submitted, the study coordinator re-sent the questionnaire to the participant and the questionnaire was completed during the FaceTime visit. For the LASST participants, the study coordinator reviewed all forms the participant completed at the study site visit and any incomplete fields were completed at the time of the study site visit.
