Infants' delayed enrollment in infant insurance poses challenges in capture of neonatal outcomes, which may be charged to the maternal health plan, posing misclassification risks.

Use of maternal claims in addition to infant claims in this cohort made minor contributions to case capture for neonatal\u2010specific outcomes, while significantly decreasing specificity of more general outcomes. Longer delays in enrollment yielded lower outcome prevalences with higher contributions of maternal claims even for neonatal\u2010specific outcomes. For small for gestational age (SGA), both maternal and infant claims contributed similar proportions of cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>These findings inform strategies for outcome ascertainment in claims\u2010based perinatal research and emphasize outcome\u2010specific case ascertainment strategies to balance sensitivity and specificity.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/pds.70328","type":"journal-article","created":{"date-parts":[[2026,1,18]],"date-time":"2026-01-18T08:25:13Z","timestamp":1768724713000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Neonatal Outcome Ascertainment in Mother\u2010Infant Paired Claims"],"prefix":"10.1002","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7040-1561","authenticated-orcid":false,"given":"Yehua","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Pharmaceutical Outcomes and Policy University of Florida  Gainesville Florida USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicole E.","family":"Smolinski","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Outcomes and Policy University of Florida  Gainesville Florida USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thuy N.","family":"Thai","sequence":"additional","affiliation":[{"name":"Department of Population Medicine Harvard Pilgrim Health Care Institute and Harvard Medical School  Boston Massachusetts USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Earl J.","family":"Morris","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Outcomes and Policy University of Florida  Gainesville Florida USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Celeste L.
