Description of intervention(s) / exposure
Beltless TransAbdominal Monitoring (TAM) The new device enables women to have complete freedom of movement in positioning in labour and birth. TAM uses fetal electrocardiography, maternal electrocardiography and electromyography to detect fetal heart rate, maternal heart rate and uterine activity. From this data, the wellbeing of the fetus may be assessed.
The efficacy of TAM has been proven and the device is TGA approved for use in Australia. This trial aims to explore the feasibility and acceptability of its use in an Australian clinical setting. Women will be recruited and consented in late pregnancy, prior to labour onset. The device is beltless and wireless and comprises 5 small, round adhesive sensors (similar in size to 12 lead ECG sensors). 4 sensors are placed around the umbilicus in a clockwise configuration, and one is placed above the pubic bone. A central 'pod' about the size of a matchbox is placed on the woman's umbilicus. A cover is applied magnetically to this pod, through which the signals are sent wirelessly to the CTG machine. The devices will be applied to the abdomens of participating women by the midwives employed in the birthing unit at the Royal Hospital for Women (RHW), Randwick, NSW, Australia, who are caring for the participating women in labour. The intervention will be delivered once at the onset of established labour and will be removed after the birth of the baby, to a maximum 48 hours. The intervention will take place in the birthing unit of the RHW. TAM will be applied by the midwives caring for the participating women. Women will not require information about applying the device. Women will be supervised and cared for throughout the duration of their labour and duration of use of the intervention.
Intervention adherence: if the device is found to be uncomfortable or unsuitable, it will be removed and the midwife will record the reason for this.

Outcomes
Primary outcome [1] 319180 0
Composite outcome: The feasibility of using the TAM device for continuous monitoring in the clinical setting: all-cause mortality and morbidity as assessed by data linkage to medical records, and qualitative data, will be synthesised with the NASSS Framework (Greenhalgh et al. BMC Medicine (2018) 16:66), a validated tool for analysing the implementation of new health technologies into clinical settings. Domains and questions in the NASSS framework include: Domain 1: the condition 1A. What is the nature of the condition or illness? 1B. What are the relevant co-morbidities? 1C. What are the relevant socio-cultural factors? Domain 2: the technology 2A. What are the key features of the technology? 2B. What kind of knowledge does the technology bring into play? 2C. What knowledge and/or support is required to use the technology? 2D. What is the technology supply model? 2E. Who owns the intellectual property (IP) generated by the technology? Domain 3: the value proposition and value chain 3A. What is the developer’s business case for the technology (supply-side value)? 3B. What is its desirability, efficacy, safety and cost-effectiveness (demand-side value)? Domain 4: the adopter system 4A. What changes in staff roles, practices and identities are implied? 4B. What is expected of the patient (and/or immediate carer) — and is this achievable by and acceptable to them? 4C. What is assumed about the extended network of lay carers? Domain 5: the organisation(s) 5A. What is the organisation’s capacity to innovate? 5B. How ready is the organisation for this technology-supported change? 5C. How easy will the adoption and funding decision be? 5D. What changes will be needed in team interactions and routines? 5E. What work is involved in implementation and who will do it? Domain 6: the wider system 6A. What is the political context for programme development, implementation and roll-out? 6B. What is the regulatory context? 6C. What is the position of professional bodies? 6D. What is the socio-cultural context (public perception, interest, expectation)? 6E. What is the nature and extent of inter-organisational networking? Domain 7: Embedding and adaptation over time 7A. How much scope is there for adapting and co-evolving the technology and the service over time? 7B. How resilient is the organisation to handling critical events and adapting to unforeseen eventualities?
