AimWomen with imminent premature labor (IPL) are transported to a tertiary hospital equipped with neonatal intensive care unit (NICU) even during the night. However, there have been no extensive studies of the occurrence rate of night IPL. The aim of this study was to determine the occurrence rate of night IPL in an area with a population of 2 million. %26lt;br%26gt;Materials and MethodsA retrospective analysis was conducted using data collected by the Sapporo Obstetric System for Emergency Patients launched in October 2008, in which women, physicians, and ambulance staff who sought appropriate obstetric/gynecological facilities available in the night (19.00-06.00hours) were informed of candidate hospitals by coordinators through telephone consultation. This system covered the Sapporo area, which has a population of 2000000 and 17000 births annually. Approximately 14% and 86% of women received antenatal care at six and 35 obstetric facilities with and without NICU, respectively, in this area. Night IPL was defined as a threatened premature labor and transport to one of six tertiary hospitals with NICU between 19.00 and 06.00hours the next morning. %26lt;br%26gt;ResultsDuring a 4-year period from 1 October 2008 to 30 September 2012, the Sapporo Obstetric System for Emergency Patients received 15823 (mean +/- standard deviation) monthly telephone consultations (range 114-218 per month). The monthly number of patients with night IPL was 3.0 +/- 2.2 (range 0-9 per month). %26lt;br%26gt;ConclusionsThe monthly number of cases of night IPL was around three among women who received antenatal care at obstetrics facilities without NICU in an area with a population of 2000000.
