With traditional methods, the data from farm animals and their environment can be collected intermittently. These sensors measure the activity, housing conditions, feed intake, and health of farm animals. A more consistent use of cough-specific measurement tools is required to better determine the nature and burden of cough in asthma.Ĭurrently, large volumes of data are being collected on farms using multimodal sensor technologies. In studies where cough was measured, the methods employed varied considerably. Clinically important levels of cough associated with impaired health status were identified in patients with asthma.Īlthough cough is a common symptom in asthma, the clinical features and accompanying healthcare burden have been studied infrequently. We found that a broad range of objective and subjective measures have been used albeit with a lack of consistency between studies. Of 12,090 citations identified after our initial search, 112 full-text articles met criteria for inclusion in our analysis. Studies included for analysis were confined to those undertaken in adult patients (≥ 18 years) with asthma of any severity where any tool or method to specifically measure cough was employed. To review the large and extensive body of literature in asthma with the specific hypothesis that the characteristics of cough and clinical impact in this disease has only occasionally been studied.įor this systematic review, we searched EMBASE and MEDLINE databases using a combination of MeSH terms for “cough” and “asthma” for studies published up to and including end of August 2021. The extent to which objective and subjective tools has been used to measure the characteristics and burden of cough in patients with asthma has not been reported.
