Our hypothesis was that the criteria would not be sufficient due to the recent advances made in perinatal care.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Preterm infants born between 2003 and 2019 and registered in the Neonatal Research Network of Japan database with a birth weight of 1500\u2009g or less or a gestational age of less than 32\u2009weeks were analyzed. The database included the clinical information of registered infants during their stay in NICUs and outcomes at 3\u2009years of age.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n The database included 73\u2009615 infants. After excluding those with an unknown outcome at discharge, 73\u2009464 infants were analyzed for short\u2010term outcomes, including mortality and morbidities. The incidence of CP at 3\u2009years of age was analyzed in 36\u2009151 infants. Furthermore, 16\u2009467 infants born between 28 and 31\u2009weeks of gestation were examined in terms of the validity of the current eligibility criteria. The mortality and incidences of severe intraventricular hemorrhage and periventricular leukomalacia significantly decreased during the study period (Cochrane\u2013Armitage test,\n p<\/jats:italic>\n \u2009<\u20090.01). Furthermore, the eligibility criteria were not sufficiently nor strongly associated with indicators for detecting perinatal hypoxia\u2010ischemia resulting in CP.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n The existing eligibility criteria of the JOCS\u2010CP used for preterm infants born between 28 and 31\u2009weeks were no longer suitable because of the advances in perinatal care in Japan.<\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/jog.15472","type":"journal-article","created":{"date-parts":[[2022,10,21]],"date-time":"2022-10-21T04:16:33Z","timestamp":1666325793000},"page":"220-231","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Validation of eligibility criteria for the Japan Obstetric Compensation System for Cerebral Palsy in preterm infants: A case\u2013control cohort study"],"prefix":"10.1111","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5318-8877","authenticated-orcid":false,"given":"Satoshi","family":"Kusuda","sequence":"first","affiliation":[{"name":"Department of Pediatrics Kyorin University Mitaka Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hidehiko","family":"Nakanishi","sequence":"additional","affiliation":[{"name":"Research and Development Center for New Medical Frontiers, Department of Advanced Medicine, Division of Neonatal Intensive Care Medicine Kitasato University School of Medicine Sagamihara Kanagawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hideaki","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Japan Obstetric Compensation System for Cerebral Palsy Japan Council for Quality Health Care Chiyoda Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"the Neonatal Research Network of Japan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,10,21]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/jog.13906"},{"key":"e_1_2_10_3_1","unstructured":"Japan Council for Quality Health Care.
