Can COPD Exacerbations Be Picked Up Early via a Weekly Medication Question Through a Smartphone Application?

This is a sub-analysis of a randomized controlled trial, not a trial of the medication question itself. The paper does not describe how participants were assigned to coaching groups. Exacerbation detection was analysed only in the 27 patients who completed 6 months, while response rate used all 42 patients. There was no comparison with a daily exacerbation questionnaire or phone call, so exacerbations may still have been missed. The response rate was 72%, and it was lower at 6 months than in the first month, so the question may not remain reliable over time. In 70% of patients with 6-month follow-up, no exacerbation occurred, so a weekly question may feel repetitive. The study was done during the COVID-19 pandemic, which may have affected exacerbation rates. Smartphone literacy and cognitive function were not formally assessed, and the sample may have been biased toward patients willing to use a smartphone.

The work was supported by Fonds Wetenschappelijk Onderzoek (FWO-Flanders), including pre-doctoral and post-doctoral fellowships and grant G0C0720N. The authors declared no commercial or financial relationships that could be construed as a potential conflict of interest.

Do not conclude that this weekly medication question reliably detects COPD exacerbations or improves patient outcomes. It was answered 72% of the time, picked up 10 of 18 recorded exacerbations in the 27 patients who completed 6 months, and response fell by 6 months. The paper did not compare the method with a daily exacerbation questionnaire or phone call, so events may still be missed.
