However, there is a lack of research on the nationwide prevalence and disease burden of CC in the Chinese population. We aim to use an insurance claims database to assess the prevalence and the corresponding economic burden owing to CC in China.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>This was a retrospective observational study based on an administrative medical insurance database in 2015, 2016 and 2017, from nine cities in North, South, East, South-West, and North-West regions of China. The study population was Chinese adults (\u2265\u200918\u00a0years old) who had been identified as CC patients.

Of these, 55.24% were women. In addition, 8.90%, 9.46%, and 8.37% of all patients in 2015, 2016, and 2017, who had applied for medical insurance, had CC, respectively, with a three-year average probability of 8.88%. The median number of outpatient visits within a calendar year was 27 per year due to any reason during the period of 2015\u20132017. The median medical cost of each patient per year increased from 935.30 USD to 1191.47 USD from 2015 to 2017.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>CC is common among medical insurance users, with a substantial utilization of medical resources, highlighting the huge burden of CC in China.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12890-024-03017-6","type":"journal-article","created":{"date-parts":[[2024,7,4]],"date-time":"2024-07-04T15:02:35Z","timestamp":1720105355000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Prevalence and disease burden of chronic cough in nine cities of China: an observational study"],"prefix":"10.1186","volume":"24","author":[{"given":"Lin","family":"Chen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kim S.J.","family":"Lao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fang","family":"Yi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai","family":"Xia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kefang","family":"Lai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,7,4]]},"reference":[{"key":"3017_CR1","doi-asserted-by":"publisher","first-page":"i1","DOI":"10.1136\/thx.2006.065144","volume":"61 Suppl 1","author":"AH Morice","year":"2006","unstructured":"Morice AH, McGarvey L, Pavord I.
