CHiRP - Centre for High Risk Pregnancy

The Department of O&G, SGH is delighted to announce the launch of CHiRP (Centre for High Risk Pregnancies).

The Department of O&G, SGH has a strong reputation for looking after high risk pregnancies, in particular mothers with medical disorders and those with complications. Being sited in a tertiary teaching hospital and an academic medical centre, we have worked hard to develop and establish one-stop joint multi-disciplinary clinics and services between obstetrics and a growing number of medical specialties.

We also work very closely with the departments of Neonatology and Anaesthesialogy, whose facilities and expertise in highly specialised intensive and critical care for preterm babies and  the unwell mothers are crucial to ensure the best possible outcomes in high risk pregnancies. Multidisciplinary forums are organised, often with other medical and surgical disciplines , to discuss management of the more complicated pregnancies. We also enjoy a close collaboration with counsellors and psychiatrists, cognisant  that mental health of the mother  is a very important and often overlooked aspect of holistic care.

These services are led by the Maternal Fetal Medicine section of the department. With the increasing complexity of cases seen and the growing number of joint clinics, the department of O&G obtained approval to form the Centre for High Risk Pregnancy (CHiRP). The intention is to optimise and streamline the coordination and operation of these services together with the other perinatal services of prenatal diagnosis under one centre. Currently the centre is a virtual one, but we hope to able to have a well sited physical space to house these services under one roof in the near future.

The aim of CHiRP is to provide a one-stop multidisciplinary tertiary integrated care service for high risk pregnancies and optimising pre-pregnancy care and counselling for prospective mothers with risk factors.
