Use of Routine Interventions in Labour and Birth in Canadian Hospitals: Comparing Results of the 1993 and 2007 Canadian Hospital Maternity Policies and Practices Surveys

Objectives: To compare policies and practices of routine interventions in labour and birth in Canadian hospitals in 1993 and 2007 and to describe trends regarding adherence to evidencebased guidelines. Methods: We used data from surveys of Canadian hospitals in 1993 and 2007 on routine maternity care practices and policies, including interventions in labour and birth. Results: The response rate of hospitals in 1993 was 91% (523/572), and in 2007 it was 92% (323/353). In 1993, 65% of hospitals (335/516) had a policy that all women should have initial electronic fetal heart rate monitoring, and in 2007, 74% (235/319) had such a policy. In 1993, 55% of hospitals (284/516) used epidural anaesthesia as one of the methods for pain control, and in 2007, 87% of hospitals (278/318) did so. In 1993, 37% of hospitals (193/521) had a "no enema/suppository" policy on admission, and in 2007, 88% (282/322) did. In 1993, 87% of hospitals (450/516) had a policy encouraging the presence of both the woman's partner and other labour support people in the room during the course of labour; in 2007, 80% (259/323) did. In 1993, hospitals estimated that 62% of primiparous women and 44% of multiparous women had an episiotomy in their units. In 2007, the episiotomy rate, irrespective of parity, was 17%. In 1993, 20% of hospitals (98/498) had a policy specifying the length of the second stage of labour, and in 2007, 33% (101/307) had such a policy. Conclusion: Positive and negative trends in adherence to best practices were seen in policies and practices of routine interventions during labour and birth in Canadian hospitals between 1993 and 2007. © 2011 Society of Obstetricians and Gynaecologists of Canada.
