Prolonged hospitalization versus home management for women with arrested preterm labour: A before-after study

Objectives. - To compare gestational age at birth and incidence of preterm birth inferior to 37 weeks of gestation (WG) in single pregnancies with either prolonged hospitalization, or early home discharge after arrested preterm labour. Patients and methods. - Management of preterm labour was changed in our public academic hospital because no evidence of benefits for prolonged hospitalization was found and because adverse effects related to long-term hospitalization were described. In this retrospective before after study, we compare the attitude A (December 2006 to April 2008), a prolonged hospitalization until 32 or 34 WG, with new attitude B (May 2008 to February 2010), an early discharge home if the cervical exam was unchanged since admission. Results. - A total of 140 patients were included: 70 in each group. Initial hospitalization stay was significantly shorter in Group B (respectively, 5.4 +/- 5.4 days and 11.4 +/- 12.1 days; P < 0.05). Preterm spontaneous delivery is 14(20%) in group A and 21(28.6%) in Group B (P > 0.05). Gestational ages at birth were 33(5/7) and 33(0/7) WG in groups A and B, respectively (P > 0.05). If we focus on patients who were discharged home in the two groups (women who did not deliver no matter the hospitalization length), the gestational age at birth (38(4/7) and 38 WG; ns) and the prematurity rate inferior to 37 WG (17.2% and 22.4%; ns) were statistically similar. Discussion and conclusion. - This study suggests that shorter hospitalization does not decrease the delivery term, nor does it increase the premature delivery incidence. (c) 2012 Elsevier Masson SAS.
