Barriers to and facilitators for use of augmentative and alternative communication and voice restorative devices in the adult intensive care unit: a scoping review protocol

BACKGROUND: Mechanically ventilated patients in the intensive care unit (ICU) experience profound communication impairment, placing them at risk for poor physical and psychological outcomes. Patient communication strategies such as augmentative and alternative communication (AAC) and voice restorative devices are recommended to facilitate communication. These strategies, however, are inconsistently adopted in ICU practice signaling utilization barriers. Our objective is to map and synthesize the current evidence-base for stakeholder-reported barriers and facilitators to patient communication strategy utilization for adults with an advanced airway in the ICU. METHODS AND ANALYSIS: We will use Arskey and O’Malley’s recommended methods to conduct a scoping review using a rapid review framework to streamline the process. A single reviewer will conduct a search and an initial screen of titles and abstracts from five electronic databases (MEDLINE, EMBASE, the Cochrane Library, Cumulative Index to Nursing and Allied Health Literature [CINAHL], and PsychInfo) from 1990 to present to identify English language peer-reviewed studies. Subsequently, two reviewers will independently screen a shorter list of studies for inclusion. We will also search the reference lists of eligible studies. Two reviewers will independently extract study characteristics, communication strategy, and stakeholder reported barriers and facilitators. We will code and categorize the extracted barriers and facilitators according to the Theoretical Domains Framework (TDF), an integrative framework of behavior change. DISCUSSION: To our knowledge, this will be the first scoping review to map and synthesize reported barriers and facilitators to communication strategy utilization in the adult ICU using a theoretical framework. The results of this scoping review will help to identify trends and gaps in the current evidence-base and support recommendations for improving patient-centered practice, policy, and research related to successfully establishing ICU patient communication.
