Longitudinal passive cough monitoring and its implications for detecting changes in clinical status.

ABSTRACT:

Research question

What is the impact of the duration of cough monitoring on its accuracy in detecting changes in the cough frequency?

Materials and methods

This is a statistical analysis of a prospective cohort study. Participants were recruited in the city of Pamplona (Northern Spain), and their cough frequency was passively monitored using smartphone-based acoustic artificial intelligence software. Differences in cough frequency were compared using a one-tailed Mann-Whitney U test and a randomisation routine to simulate 24-h monitoring.

Results

616 participants were monitored for an aggregated duration of over 9 person-years and registered 62 325 coughs. This empiric analysis found that an individual's cough patterns are stochastic, following a binomial distribution
