Data were extracted from BadgerNet, maternity records, and delivery suite databases; Fisher's exact test was used for categorical comparisons.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Of 126 IUT episodes, 53 (42%) delivered at the tertiary centre; median transfer\u2010to\u2010delivery interval was 1\u2009day (mean 2.02). Delivery rates averaged ~10%\/day over the first 5\u2009days. Transfers from outside the local network delivered within 24\u2009h more often (18%). Among 73 (58%) who did not deliver, median length of stay was 4\u2009days. Delivery was less likely at 22\u201324\u2009weeks (32% vs. 50% at \u2265\u200925\u2009weeks) and significantly associated with sepsis (\n p<\/jats:italic>\n \u2009=\u20090.01), chorioamnionitis (\n p<\/jats:italic>\n \u2009<\u20090.001), pathological CTG (\n p<\/jats:italic>\n \u2009=\u20090.006), and Doppler abnormalities (\n p<\/jats:italic>\n \u2009=\u20090.02).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Over half of women undergoing IUT did not deliver during admission.
