Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Women in the intervention arm will receive 2 virtual consultations on asthma management in pregnancy. These virtual consultations will use either a phone or a video platform to provide care. The consultations will cover clinical assessment (e.g., exacerbation history, asthma symptom control, triggers etc.), feedback and asthma self-management education. Each session will take approx. 30 minutes. The first session will be scheduled soon after the randomisation and provided by a nurse specialist. A respiratory physician will complete the second session within 8 weeks from the randomisation. An intervention manual will be developed to guide intervention providers, and the treatment recommendations will follow asthma guidelines. A structured asthma assessment form will be used to standardise the assessments.

Comparator / control treatment
Women in the control arm will receive 2 face-to-face consultations on asthma management in pregnancy. The consultations will cover clinical assessment (e.g., exacerbation history, asthma symptom control, triggers etc.), feedback and asthma self-management education. Each session will take approx. 30 minutes. The first session will be scheduled soon after the randomisation and provided by a nurse specialist. A respiratory physician will complete the second session within 8 weeks from the randomisation. Both face-to-face and virtual interventions will provide the same structured asthma care and use the same asthma assessment form.

Outcomes
Primary outcome [1] 328945 0
The primary outcome will be the uptake of the model of maternal asthma care. The number of women who undertake virtual maternal asthma care (as a proportion of those allocated this care) will be compared to the number who undertake face-to-face maternal asthma care (as a proportion of those allocated this care). The intervention providers will maintain a record of participants who attended the intervention. These records will be audited to assess the uptake of the intervention.
Timepoint [1] 328945 0
Both intervention sessions will be completed within 2 months from the enrolment. The uptake of intervention by each participant will be assessed at the completion of this intervention period.
Secondary outcome [1] 400909 0
Self-reported exacerbation control during the follow-up telephone interview
Timepoint [1] 400909 0
4 months after enrolment
Secondary outcome [2] 401145 0
Self-reported asthma symptom control assessed using Asthma Control Questionnaire (ACQ-5)

Secondary outcome [3] 401146 0
Feasibility and Acceptability – facilitators and barriers of implementation: qualitative interviews will be used to explore the facilitators and barriers of program implementation
Timepoint [3] 401146 0
4 months after enrolment
Secondary outcome [4] 401147 0
Intervention fidelity (i.e., the proportion of women who completed both appointments). The intervention providers will maintain a record of participants who attended the intervention. These records will be audited to assess the uptake of the intervention.

Timepoint [4] 401147 0
Both intervention sessions will be completed within 2 months from the enrolment. The Intervention fidelity for each participant will be assessed at the completion of this intervention period.
Secondary outcome [5] 402424 0
Participants’ satisfaction with the service will be assessed using Global Evaluation of Efficacy

Summary
Brief summary
The Virtual Model of Antenatal Asthma Care (VMAC) study evaluates the suitability of 2 types of asthma care in pregnancy. 1) virtual (tele/video conferencing) and 2) face-to-face (in person).
Uncontrolled asthma in pregnancy may harm the mother and the baby. Self-management education and clinical care may help to control asthma throughout pregnancy. Traditionally, it is provided as a face-to-face service which largely depends on the availability of both the mother and the healthcare team. To address this, we have developed a virtual model of care to provide the same service remotely (i.e., via tele or video conferencing). Women can access care at a convenient place and time. In this study, we are testing the suitability of this new approach.
