Table 2 Mapping of variables and indicators to implementation outcomes and how calculated

Adoption

Project ID (device data) and project progress (admin data)

Site ID (device data) and site progress (admin data)

Number of projects that expressed interest in the pilot who actually ‘went live’

Number of sites that expressed interest in the pilot who had at least one project that ‘went live’

Penetration

Pseudonymised clinician identifier (device data) and number of trained clinicians (admin data)

Number of trained clinicians divided by number of clinicians using the device

Pseudonymised patient identifier (device data) and number of trained patients (admin data, Home device only)

Number of trained patients divided by number of patients using the device (Home device only)

Sustainability

Site and project ID (device data) and whether signed up to pilot extension (admin data)

Frequency count of the number of sites and projects that signed up to the pilot extension period.

Fidelity

Examination and whether performed using device (device data)

Frequency count and proportion of examinations performed using the device (as planned) versus not (using different equipment).

Feasibility

Real-time clinician pop-up question #3: whether the examination had to be repeated due to poor quality

Frequency count of number and proportion of care episodes needing to be repeated due to poor quality.

Cost

Site and project ID, duration of contact, type of contact, clinician type, device type (all device data) and site and project progress, and clinicians and patients trained and device licencing (all admin data).
