Highlights: First 100 Babies Report

Ryde Group Midwifery Practice

The Ryde Group Midwifery Practice

Ryde Midwifery Group Practice was launched on 15th March 2004. A six months transition period followed. This is a report card of the first 100 intended bookings at Ryde. The Ryde Midwifery Group Practice offers the benefits of continuity of midwifery care to low risk non-insured women who book with a named midwife at their local hospital. Midwives and women are guided by the National Midwifery Guidelines for Consultation and Referral to decide where to book – Royal North Shore Hospital, or Ryde. Primary level maternity and newborn care is offered at Royal North Shore and Ryde Hospitals for families from a culturally and linguistically diverse (CALD) population. In this first evaluation of the new service there were no maternal or neonatal adverse outcomes. All babies were born in good health and were discharged home with their mothers after birth. Ryde Midwifery Group Practice was Highly Commended in the NSW State Treasury Managed Funds Risk Management Awards.

A free standing birth centre is an institution that offers care to women with a straightforward pregnancy and where midwives take primary professional responsibility for care. During labour and birth medical services, including obstetric, neonatal and anaesthetic care are available should they be needed, but they may be on a separate site which may involve transfer by car or ambulance.

Compared with Australian national data (2002), the RMGP shows a significantly higher rate of spontaneous vaginal birth, lower Caesarean section and lower instrumental birth rate. This may be associated with the lack of induction and the lack of epidurals at Ryde.

During the antenatal period, the midwives referred 30 women to RNS hospital (29%). Of these women 13 booked in to RNS without any consultation at Ryde; others were transferred when antenatal factors developed. The RMGP midwives continued to provide labour and birth care for 8 women who transferred to RNS to give birth. The transfer rate shows a conservative index of referral and consultation with obstetric care at RNS consistent with expectations of the new midwifery led model, and compares favourably with other published rates (see refs). Six families left the district after booking with the RMGP.

Reasons for antenatal transfer included:

  • Induction of labour (11)
    • post dates pregnancy (8) referred at 41 completed weeks
    • Hypertension (3)
  • PROM (2)
  • Hypertension in pregnancy (3)
  • Gestational diabetes (2)
  • Pre-term (2)
  • Antepartum bleeding (1)
  • Previous PPH (1)
  • Congenital anomaly (2)
  • Ryde hosp. closed (1)
  • serious medical conditions apparent at booking in (5)

During labour 11 women who began labour at Ryde were transferred to give birth at RNS. Of these women; 7 were transferred by ambulance; and the others travelled in their own car. Average time between calling the ambulance and arrival was 13 minutes (range 0-30 mins). Average transfer time by ambulance 21 minutes (10 -30 mins). Average time from arrival until consultation at RNS was 13 mins (5-25 mins).

Reasons for intrapartum transfer included:

Prolonged 2nd stage (5) resulting in:

  • C Sections (2)

  • C Section (3)

Requested epidural (2) resulting in:
