The hospital inpatient claims for asthma were acquired from the National Health Insurance database in 2015. A multivariate linear regression was performed with the hospitalization rate for asthma as a dependent variable. The annual ambient concentration of CO showed a negative association with the hospitalization rates for asthma while that of sulfur dioxide showed a positive association. The number of primary care physicians showed a negative association with the hospitalization rates for asthma while the number of beds in hospitals with less than 300 beds showed a positive association. The negative association of the ambient concentration of CO with the hospitalization rates for asthma showed results upon further investigation.<\/jats:p>","DOI":"10.3390\/ijerph17041244","type":"journal-article","created":{"date-parts":[[2020,2,19]],"date-time":"2020-02-19T04:06:01Z","timestamp":1582085161000},"page":"1244","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Regional Variation of Hospitalization Rates for Asthma in Korea: Association with Ambient Carbon Monoxide and Health Care Supply"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6616-2534","authenticated-orcid":false,"given":"Agnus M.","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Health Policy and Management, Seoul National University College of Medicine, Seoul 03080, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4876-3205","authenticated-orcid":false,"given":"Sungchan","family":"Kang","sequence":"additional","affiliation":[{"name":"Graduate School of Public Health, Seoul National University, Seoul 08826, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jong Heon","family":"Park","sequence":"additional","affiliation":[{"name":"National Health Insurance Service, Wonju 26464, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7257-1679","authenticated-orcid":false,"given":"Yoon","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Health Policy and Management, Seoul National University College of Medicine, Seoul 03080, Korea"},{"name":"Institute of Health Policy and Management, Medical Research Center, Seoul National University, Seoul 03080, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2163","DOI":"10.1016\/S0140-6736(12)61729-2","article-title":"Years lived with disability (YLDs) for 1160 sequelae of 289 diseases and injuries 1990\u20132010: A systematic analysis for the Global Burden of Disease Study 2010","volume":"380","author":"Vos","year":"2012","journal-title":"Lancet"},{"key":"ref_2","first-page":"602","article-title":"Environmental issues in managing asthma","volume":"53","author":"Diette","year":"2008","journal-title":"Respir.
