In addition, in approximately 70% of the facilities, diagnosis was made after discussions various among medical teams. In approximately 80% of the centers, the chest radiography used for CLD diagnosis were evaluated by multiple doctors. Furthermore, some centers used chest X\u2010rays that were taken at approximately 28\u2009days of age for CLD diagnosis, whereas at other facilities, diagnosis was made regardless of time at which the chest radiography were obtained. Only a small number of centers have established criteria for determining the necessity of oxygen at the corrected age of 36\u2009weeks, and the target saturation of peripheral oxygen levels also tend to vary for each facility. Whether the conditions wherein the patient receives respiratory support for apnea or respiratory tract diseases should be considered as CLD also differed among the facilities.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>It is necessary to reassess the definition and classification of CLD in Japan to accurately evaluate and improve the quality of respiratory management based on the long\u2010term prognosis.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/ped.15184","type":"journal-article","created":{"date-parts":[[2022,3,4]],"date-time":"2022-03-04T05:27:22Z","timestamp":1646371642000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["The status of chronic lung disease diagnosis in Japan: Secondary publication"],"prefix":"10.1111","volume":"64","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8084-4451","authenticated-orcid":false,"given":"Masato","family":"Ito","sequence":"first","affiliation":[{"name":"Department of Pediatrics Akita University Graduate School of Medicine  Akita Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7004-6608","authenticated-orcid":false,"given":"Seiichi","family":"Tomotaki","sequence":"additional","affiliation":[{"name":"Department of Neonatology Kanagawa Children's Medical Center  Yokohama Kanagawa Japan"},{"name":"Neonatal Intensive Care Unit Department of Pediatrics Kyoto University Hospital  Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3669-883X","authenticated-orcid":false,"given":"Tetsuya","family":"Isayama","sequence":"additional","affiliation":[{"name":"Division of Neonatology National Center for Child Health and Development  Setagaya\u2010ku Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroko","family":"Hara","sequence":"additional","affiliation":[{"name":"Department of Radiology Kurashiki Central Hospital  Kurashiki Okayama Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3148-9892","authenticated-orcid":false,"given":"Katsuya","family":"Hirata","sequence":"additional","affiliation":[{"name":"Department of Neonatal Medicine Osaka Women's and Children's Hospital  Izumi Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1415-4831","authenticated-orcid":false,"given":"Hirokazu","family":"Arai","sequence":"additional","affiliation":[{"name":"Department of Neonatology Akita Red Cross Hospital  Akita Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,6,21]]},"reference":[{"key":"e_1_2_9_2_1","first-page":"489","article-title":"A new form of respiratory disease in premature infants","volume":"99","author":"Wilson MG","year":"1960","journal-title":"AMA J.
