Table 2. Key facilitators and barriers to atrial fibrillation screening service proposed mapped against the most relevant TDF domains (n = 25 for patients, n = 9 for GPS and n = 4 for pharmacists).

TDF domain(s)	Facilitators	Stakeholder group(s)	Barriers	Stakeholder group(s)
Environmental context and resources	Space and established general practice infrastructure	All	Busy clinic environment	All
	Advantages of single-lead ECG	Patients and pharmacists	Accessibility of community pharmacy	Pharmacists and patients
	Presence of HCP	Patients	Service costs and resources	Patients and GPS
			Variation in practice culture and poor service integration	Pharmacists
			Variable access to care	Patients
			Logistics of same-day screening	Patients
Goals	Prioritisation of at-risk groups	All	Screening led by other HCPs	Pharmacists and patients
	Flexible choice of appointment	Patients and GPS	Self-testing technology	Patients
	Engagement of stakeholders	Pharmacists	Self-testing technology	Patients
Social or professional role and identity	Utilisation of pharmacists’ skills	All	Misconceptions about pharmacists	Patients and GPS
Social or professional role and identity	Development of pharmacists’ roles	Pharmacists	Unconventional role of pharmacists	Pharmacists
Knowledge and social influences*	Knowledge and awareness	Patients and GPS	Getting used to novel screening	Patients
Knowledge and social influences*	Staff inclusion in service provision	GPS	Lack of communication with staff	GPS

*Knowledge and social influences are two separate domains but are combined in this table because some facilitators/barriers mapped onto both domains.
