Description of intervention(s) / exposure
The trial tests an intervention involving a Multidisciplinary Approach to Management of Maternal Asthma (MAMMA[copyright]). This intervention will embrace a collaborative approach involving the participants’ family physician, pharmacist and asthma educator. Asthma education, monitoring, feedback and follow-up are integral components of the monthly intervention. Every month, participants in the intervention group will be contacted for an hour session by the trial’s nominated pharmacist to assess their asthma control by administrating Juniper's Asthma Control Questionnaire (ACQ) and a short data collection form which inquires about oral corticosteroid use, asthma related hospital admissions and days off work and preventer to reliever use ratio. They will be followed up every month till delivery (7-9 months duration depending on when they had their first outpatient visit). The ACQ states that an increase in a score of 0.5 is a clinically significant deterioration of asthma control. The trial’s pharmacist will feedback to the participant’s nominated family physician if their ACQ score has increased by 0.5 or greater and if there has been a documented exacerbation since the last monthly visit. The pharmacist and family physician will then collaborate on appropriate step up therapy for the participant. It is anticipated that this close monthly monitoring will maintain the participant’s asthma under tight control during pregnancy. Each participant in the intervention group will be given a handheld device (PiKo-6) for home monitoring of lung function which they can use as often as they please but we will ask for their latest result at the monthly visits. They will receive a medication management review, periodic review of inhaler device technique, instruction in the use of PiKo-6, trigger avoidance and smoking cessation support (if relevant). The intervention group will also have their FEV1/FEV6 observed during the trial every month. This information will be oberservational data only as we are exploring this value as a marker for asthma control during pregnancy. We will not be using this ratio to determine medication dosage changes during the trial.

Comparator / control treatment
Standard usual care. Women in the control group will continue having their regular outpatient visits at the antenatal clinics as per usual (ranging from monthly to weekly depending on their obstetrician's discretion). They will receive no intervention. The only form of education they will receive during the trial is an "Asthma during pregnancy" education pamphlet at the start of the trial which is written by the Asthma Foundation of New South Wales. Unlike the control group, they will not receive any asthma monitoring or additional education.

Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Three recruitment methods will be used to ensure the sample size is reached efficiently.
1. Advertisement posters publicising the trial will be placed in the outpatient department along side an expression of interest box where participants can leave their contact details. Study packs (includes an explanatory statement with an expression of interest form and a reply paid envelope) will also be available in the outpatient department so potential participants can take the information home to read and post back expression of interest forms.
2. Midwives will also be asked to help identify eligible pregnant women with asthma during their first outpatient visit. They will be asked to approach any woman who has indicated they are asthmatic and hand them a study pack, which will be available in the outpatient department. Midwives will only be identifying women. Our researchers will seek consent after receiving expression of interest forms. Midwives will be notified of this study through email.
3. A list of pregnant asthmatic women who have had their first outpatient visit will be generated weekly from the BOS (registered trademark)/IPM (registered trademark) database (a medical records’ database which stores antenatal information for all hospital patients). Study packs will be posted to the women who are on each weekly list.

During the recruitment phase, each participant will be asked to nominate their preferred family physician to be involved in the trial and to bear the responsibility of their asthma management during pregnancy.

Group allocation
At time of consent, participants asthma severity will be assessed in accordance with the National Asthma Handbook classifications and randomisation will be stratified according to asthma severity. Participants will be allocated to three groups; mild intermittent asthmatics, moderate-persistent asthmatics and severe-persistent asthmatics. Within these strata, simple randomization will be conducted using the sealed opaque envelope method to allocate participants to the usual care group (UCG) or the multidisciplinary care group (MCG), to ensure a balance of asthma severities between groups. Outcome assessors will be blinded to participant group allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Consenting pregnant asthmatic women will be randomly assigned to intervention and control groups by an investigator with the help of numbered envelopes. The envelope numbers for each participant will be decided by simple number sequence generation using Excel.

Summary
Brief summary
Background: Uncontrolled asthma during pregnancy is associated with the maternal hazards of disease exacerbation, and perinatal hazards including intrauterine growth restriction and preterm birth. Interventions directed at achieving better asthma control during pregnancy should be considered a high priority in order to optimise both maternal and perinatal outcomes. Poor compliance with prescribed asthma medications during pregnancy and suboptimal prescribing patterns to pregnant women have both been shown to be contributing factors that jeopardise asthma control. The aim is to design and evaluate an intervention involving multidisciplinary care for women experiencing asthma in pregnancy.

Methods/Design: A randomized controlled trial testing a Multidisciplinary Approach to Management of Maternal Asthma (MAMMA[copyright]) which involves education and regular monitoring. Pregnant women with asthma will be recruited from antenatal clinics of one maternity hospital in Victoria, Australia. Recruited participants, stratified by disease severity, will be allocated to the intervention or the usual care group in a 1:1 ratio. Both groups will be followed prospectively throughout pregnancy and outcomes will be compared between groups at three and six months after recruitment to evaluate the effectiveness of this intervention. Outcome measures include Asthma Control Questionnaire (ACQ) scores, oral corticosteroid use, asthma exacerbations and asthma related hospital admissions, and days off work, preventer to reliever ratio, along with pregnancy and neonatal adverse events at delivery. The use of FEV1/FEV6 will be also investigated during this trial as a marker for asthma control.

Discussion: If successful, this model of care could be widely implemented in clinical practice and justify more funding for support services and resources for these women. This intervention will also promote awareness of the risks of poorly controlled asthma and the need for a collaborative, multidisciplinary approach to asthma management during pregnancy. This is also the first study to investigate the use of FEV1/FEV6 as a marker for asthma control during pregnancy.
