Purpose: Communication with nonspeaking patients is a critical challenge of person-centered care. This scoping review aimed to map the literature on augmentative and alternative communication (AAC) interventions for nonspeaking mechanically ventilated and tracheostomy patients in critical and acute care settings.

Method: Electronic database, ancestry, and forward citation searches were conducted using eligibility criteria established a priori. Data were extracted, synthesized, and summarized according to scoping review methodology. Studies were categorized by type of intervention and summarized in terms of purpose, participants, design, quality appraisal (including validity and reliability of selected efficacy measures), and efficacy.

Results: Small-to-large treatment effect sizes indicated demonstrable impact on patient health and communication efficacy with high-tech and no-tech visual interface–based interventions and systematic nurse training interventions. Treatment effects primarily pertained to dependent variables of patient anxiety, communication satisfaction, comfort, symptom self-reporting, and nursing practice changes.

Conclusions: There is a paucity of high-quality AAC intervention research for mechanically ventilated and tracheostomy patients in critical and acute care settings. Emergent evidence suggests that select visual interface and nurse training interventions can impact efficacy of patient–provider communication and patients’ overall health.
