Barriers and facilitators to the intervention implementation by Consolidated Framework Implementation Research domains and constructs. (Adapted from CFIR codebook) [21]

CFIR domains and constructs	Barriers and facilitators
Innovation characteristics
Adaptability	Facilitator: MaTI was adapted to reflect differing information transfer systems, staff roles, family and patient involvement, and ways of working.
Complexity	Barrier: Completion of medicine discharge log (Step 4) was complex in finding the correct time to complete it.
Design quality and packaging	Facilitator: The patient toolkit was felt to have benefited staff and patients. Helped staff discuss medicines with patients. The structure, colour and style were appealing.
Outer setting
Patient needs and resources	Facilitator: Some staff were motivated to deliver intervention components when they felt it addressed patient needs. Patient education was regarded as important for supporting patients to continue monitoring and understanding their medicines.
External policy and incentives	Facilitator: Pharmacist practice and education, supported the delivery of the intervention in some sites.
Cosmopolitism	Barrier: Hospitals not well networked with community pharmacy. Lack of receptiveness of community pharmacy to the intervention in relation to contact community pharmacist (Step 2b), information transfer to community pharmacy (Step 6) and check community pharmacist received information (Step 7).
Inner setting
Networks & Communications	Facilitator: Existing communication systems and relationships supported implementation of the intervention steps which were delivered over a lengthy period of time.
Culture	Facilitator: Person-centred care, safety, clan, and hierarchical culture.
Implementation Climate	Facilitator: The intervention was compatible with existing practice as it was close to the norm. Barrier: Channels of communication between hospital and pharmacy unreliable. Relative priority of MaTI intervention reduced given competing sources.
Readiness for Implementation	Barrier: Two of the lesser implemented steps of MaTI, contact community pharmacist (Step 2b) and completion of medicines discharge log (Step 4), were impacted by resource deficiencies.
Characteristics of Individuals
Knowledge & Beliefs about the Innovation	Barrier: Staff reported some patients felt the intervention was already being carried out in community pharmacy. Some ward staff lacked enthusiasm for the intervention.
Other Personal Attributes	Facilitator: Site coordinator ability to increase staff confidence and sense of self-efficacy in delivering MaTI.
Process
Planning	Facilitator: Developing a Standard Operating Procedure to implement transfer of patient information to community pharmacy in one site.
Engaging	Barrier: Patient engagement not encouraged as much in some sites e.g., asking questions. Facilitator: Pharmacist highly engaged in delivering intervention in one site. Training cited as important in some sites.
Executing	Barrier: Completion of medicines discharge log (Step 4) had poor implementation across sites.
