Barriers and facilitators for the implementation of an IAC in a care region of Canton BL

Barriers
Preparation phase
Political and legal context	Meso-level: • The care law does not specify how community care providers will collaborate with the IAC, thus there is no obligation for them to refer older adults to the IAC.
Socio-cultural context	Meso-level: • Conflicting interests of all actors involved in care, leading to different attitudes and perceptions towards the IAC services. • Presence of multiple community care providers for older adults with different outcome expectations regarding the IAC. • Insufficient/contradictory information on services available in the care region, making older adults, caregivers and community care providers less likely to be aware of and contact the IAC.
Implementation phase
Setting	Micro-level: • The IAC management leads the promotion of the IAC with low front-line engagement.
Facilitators
Preparation phase
Socio-cultural context	Meso-level: • A champion among the research team: a family physician, head of the department of Family Medicine of the local university who voluntarily and enthusiastically contributes with ideas to overcome the barriers and facilitate the promotion of the IAC. • The members of the community, part of the cantonal group of this project, include representatives of health and social care organizations, family physicians, nurses, social workers and other health professionals, as well as representatives of senior organizations and caregivers. They contributed in the identification of barriers and provided recommendations on strategies to reach older adults.
