Our aim is to evaluate the frequency of cerclage placement in consecutive pregnancies with preterm birth history to determine whether performing serial cervical length screening for women with a history of late (34\u201336 6\/7 weeks) spontaneous preterm birth (SPTB) should be reconsidered. METHODS: Retrospective evaluation of cerclage frequency and gestational age of delivery for consecutive singleton births for 69,671 women whose first birth was a SPTB. RESULTS: History of late SPTB was associated with a lower frequency of cerclage than history of early SPTB (0.83% vs 4.88%, OR 0.16, 95% CI 0.14\u20130.18). Rates of recurrent SPTB were lower for women with history of late SPTB than those with history of early SPTB (13.45%, 3.74% early, 9.71% late vs 20.69%, 9.12% early, 11.57% late). CONCLUSION: Women with a history of late PTB have a lower risk of recurrent PTB than those with a history of early PTB but constitute most of those undergoing serial cervical length screening for potential cerclage placement. Practice guidelines for screening women with a history of late PTB should be re-evaluated.<\/jats:p>","DOI":"10.3233\/npm-210834","type":"journal-article","created":{"date-parts":[[2022,4,5]],"date-time":"2022-04-05T11:24:08Z","timestamp":1649157848000},"page":"627-633","source":"Crossref","is-referenced-by-count":0,"title":["Frequency of cerclage in consecutive pregnancies of women with history of preterm birth"],"prefix":"10.1177","volume":"15","author":[{"given":"Arian","family":"Khorshid","sequence":"first","affiliation":[{"name":"Department of Obstetrics & Gynecology, Stanford University School of Medicine, Stanford, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jonathan","family":"Mayo","sequence":"additional","affiliation":[{"name":"March of Dimes Prematurity Research Center at Stanford University, Department of Pediatrics, Stanford, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jane","family":"Chueh","sequence":"additional","affiliation":[{"name":"Department of Obstetrics & Gynecology, Stanford University School of Medicine, Stanford, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gary M.","family":"Shaw","sequence":"additional","affiliation":[{"name":"March of Dimes Prematurity Research Center at Stanford University, Department of Pediatrics, Stanford, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Stevenson","sequence":"additional","affiliation":[{"name":"March of Dimes Prematurity Research Center at Stanford University, Department of Pediatrics, Stanford, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amen","family":"Ness","sequence":"additional","affiliation":[{"name":"St. Elizabeth Medical Center, Boston, MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"key":"10.3233\/NPM-210834_ref2","doi-asserted-by":"crossref","first-page":"375.e1","DOI":"10.1016\/j.ajog.2009.08.015","article-title":"Multicenter randomized trial of cerclage for preterm birth prevention in high-risk women with shortened midtrimester cervical length","volume":"201","author":"Owen","year":"2009","journal-title":"Am J Obstet Gynecol.
