Augmentative and Alternative Communication Interventions in Critical and Acute Care With Mechanically Ventilated and Tracheostomy Patients: A Scoping Review.

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.

Effects of an Augmentative and Alternative Communication Intervention Package on Socio-Communicative Behaviors Between Minimally Speaking Autistic Children and Their Peers.

PURPOSE: The purpose of this study is to investigate the effectiveness of an augmentative and alternative communication (AAC) intervention package consisting of systematic instruction and aided modeling with speech-output technologies on the acquisition, maintenance, and generalization of socio-communicative behaviors-initiating a request for a turn, answering questions, and commenting-in four, minimally speaking (MS) autistic children between the ages of 6 and 9 years. METHOD: A multiple-probe design across behaviors replicated across participants was implemented to evaluate the effects of systematic instruction and aided modeling on initiating requests for a turn, answering questions, and commenting behaviors. Additionally, a pre- and posttreatment multiple-generalization-probes design was used to assess generalization across peers. RESULTS: Visual analyses demonstrated experimental control for two participants (i.e., Derek, Ajay) showing a functional relationship between the intervention and outcomes across all social communicative behavior. For one participant (i.e., Matthew), experimental control could not be established because he did not reach the learning criterion for commenting. The fourth participant (i.e., John) transferred to a different school after making some progress on requesting. Effect size indicator analyses corroborated these findings, indicating medium-to-strong effects for initiating requests for a turn strong effects for answering questions, and medium-to-strong effects for commenting. Generalization of socio-communicative behaviors from researcher to a typically developing peer was variable across participants. Participants maintained socio-communicative behaviors 3 weeks after the last intervention session with varying degrees of success. CONCLUSION: The outcomes of this study suggest that aided modeling and systematic instruction using speech-output technologies may lead to gains in socio-communicative behaviors in some MS autistic children.
