The aim of  this observational study was to identify time-dependent variations in CS and  vaginal delivery rates over a period of 11 years.\n        METHOD:  All deliveries (13,701 deliveries during the period 1999\u20132009) at the University  Women\u2019s Hospital Bern were analysed using an internationally standardised and  approved ten-group classification system. Caesarean sections on maternal  request (CSMR) were evaluated separately.\n        RESULTS:  We detected an overall CS rate of 36.6% and an increase in the CS rate over  time (p &lt;0.001). Low-risk profile groups were the two largest populations  and displayed low CS rates, with significantly decreasing relative size over  time. The relative size of groups with induced labour increased significantly,  but this did not have an impact on the overall CS rate. Pregnancies complicated  by breech position, multiple pregnancies and abnormal lies did not have an  impact on overall CS rate. The biggest contributor to a high CS rate was  preterm delivery and the existence of a uterine scar from a previous CS. CSMR  was 1.45% and did not have an impact on the overall CS rate.\n        CONCLUSION:  The observational study identified wide variations in caesarean section and  vaginal delivery rates across the groups over time, and a shift towards  high-risk populations was noted. The biggest contributors to high CS rates were  identified; namely, previous uterine scar and preterm delivery. Interventions aiming  to reduce CS rates are planned.<\/jats:p>","DOI":"10.4414\/smw.2014.13921","type":"journal-article","created":{"date-parts":[[2014,7,3]],"date-time":"2014-07-03T09:32:03Z","timestamp":1404379923000},"page":"w13921","source":"Crossref","is-referenced-by-count":1,"title":["Analysis  of caesarean section rates over time in\u00a0a\u00a0single Swiss centre using a ten-group  classification system"],"prefix":"10.57187","volume":"144","author":[{"given":"Martin","family":"M\u00fcller","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Kolly","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marc","family":"Bauman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sara","family":"Imboden","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Surbek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"36756","published-online":{"date-parts":[[2014,2,9]]},"container-title":["Swiss Medical Weekly"],"original-title":[],"link":[{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/1821\/2525","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/1821\/2526","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/1821\/2525","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,15]],"date-time":"2025-08-15T05:13:40Z","timestamp":1755234820000},"score":1,"resource":{"primary":{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/view\/1821"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,2,9]]},"references-count":0,"journal-issue":{"issue":"0708","published-online":{"date-parts":[[2014,2,10]]}},"URL":"https:\/\/doi.org\/10.4414\/smw.2014.13921","relation":{},"ISSN":["1424-3997"],"issn-type":[{"type":"electronic","value":"1424-3997"}],"subject":[],"published":{"date-parts":[[2014,2,9]]}}}
