Pregnant women are exposing themselves and their unborn babies to unnecessary risk by stopping their asthma medication without consulting their doctor.

Pregnant women suffering from asthma could better manage the condition if additional integrated care involving education and monitoring was introduced in Australian hospitals, a new study has found.

In research published in a leading respiratory journal CHEST, Centre for Medicine Use and Safety (CMUS) researchers at Monash University found a significant improvement in asthma control among pregnant women receiving a pharmacist-led model of care for asthma management involving education and regular monitoring in collaboration with the patient's general practitioner. Women in the early stages of pregnancy and who had used asthma medications in the previous year received the pharmacist-led monthly intervention (MAMMA©) providing asthma education, monitoring, feedback and follow-up in the antenatal clinics of two major Australian maternity hospitals - The Royal Women's Hospital and Mercy Hospital for Women.

After six months of care, results demonstrated that the women receiving the intervention had clinically and statistically better control of their asthma, when compared to a control group of pregnant women not receiving the intervention. In the intervention group, no asthma-related oral steroid use, hospital admissions, emergency visits or days off work were reported during the trial. The research follows earlier work by the researchers published in The Journal of Asthma, which found that pregnant women are exposing themselves and their unborn babies to unnecessary risk by stopping their asthma medication without consulting their doctors. A lack of confidence and/or knowledge among healthcare professionals in managing deteriorating asthma in pregnancy has also been found.

In the latest trial, 70 per cent of the participants revealed they were unaware of the risks of poorly controlled asthma, 32 per cent reported ceasing or reducing their medications since becoming pregnant.

Lead investigator, Angelina Lim of CMUS, said the simple intervention showed promise for asthma sufferers and could be widely implemented in maternal health settings without incurring extra resources.

"With one in eight pregnant women suffering from asthma, this research is telling us we need to improve management during pregnancy by finding new strategies to improve education and awareness," Ms Lim said.

"Poorly controlled asthma during pregnancy is hazardous for the health of the mother and the baby and have been associated with an increased risk of preterm birth, low birth weight, and pre-eclampsia.

"Proper asthma management among pregnant women should be regarded as a leading priority in antenatal care. This is a simple intervention that could be easily implemented in antenatal settings with minimal additional resources."

Ms Lim said larger studies were needed to demonstrate the improvements in asthma control led to improved maternal and perinatal outcomes.
