Barriers to and facilitators for the use of augmentative and alternative communication and voice restorative strategies for adults with an advanced airway in the intensive care unit: A scoping review.

Purpose: To identify barriers and facilitators for the use of augmentative and alternative communication (AAC) and voice restorative strategies for adult patients with an advanced airway in the intensive care unit (ICU).
Materials and Methods: Scoping review searching five databases between 1990 and 2019. We screened 13, 167 citations and included all study types reporting barriers and/or facilitators to using communication strategies in an ICU setting. Two authors independently extracted and coded reported barriers and facilitators to the Theoretical Domains Framework (TDF) domains.
Results: Of the 44 studies meeting inclusion criteria 18 (44%) used qualitative, 18 (44%) used quantitative, and 8 (18%) used mixed methods. In total, 39 unique barriers and 46 unique facilitators were identified and coded to the domains of the TDF. Barriers were most frequently coded to the Skills, Environmental Context and Resources, and Emotion domains. Facilitators were most frequently coded to Reinforcement, Environmental Context and Resources, and Social and Professional Roles/Identity domains. Thematic synthesis produced four potentially modifiable factors: context, emotional support, training, and decisional algorithms.
Conclusions: Identified barriers (skills, environment, resources, emotions) and facilitators (reinforcement, resources, roles) to ICU communication strategy use in the literature may be modified through formal training and role support.
