Nonverbal Communication clinical trials

Vidatalk Communication Application: Usability, Acceptability and Efficacy Study

This Phase II Small Business Technology Transfer Research (STTR) will deliver a comprehensive patient communication solution for communication-impaired patients in the intensive care unit that may help decrease days in delirium, decrease anxiety levels, and reduce sedation exposure which are proximal outcomes known to be associated with decreased mechanical ventilation days, shorter lengths of ICU and hospital stay, and lower healthcare cost. The primary goal of this Phase II STTR proposal is to further define user requirements and product specifications and develop a prototype of VidaTalk, a patient-centric, touch pad communication software, to provide mechanically ventilated (MV) patients an evidence-based solution for effectively communicating their needs to care providers and family. A secondary goal is to test the impact of the VidaTalk on clinical outcomes. This study will use mixed methods including observations and interaction with hospitalized patients as they use the VidaTalk tool, surveys and medical record data extraction, product evaluation and brief interview, satisfaction surveys with family members of ICU patients, and focus groups with Registered Nurses. Specific Aim 1. Develop a commercial prototype of VidaTalk that will include multilingual and customizable messages, compatibility with tablet devices, picture symbols, and integration with mobile communication devices. Specific Aim 2. Demonstrate usability with iterative user assessment testing in a clinical setting. Specific Aim 3. Test the clinical efficacy of VidaTalk via android application with MV patients by examining qualitative and quantitative endpoints in a clinical setting. Aim 3 hypothesis: MV patients using VidaTalk will demonstrate significant reductions in patient-reported communication difficulty and frustration, anxiety, sedation exposure, delirium/coma-free days, and improved patient and family satisfaction with ICU care compared to MV patients receiving attention-control (i.e., tablets with health education application). Specific Aim 4. Validation of electronic visual analogue scale, versus current standard paper scale. Specific Aim 5 a, b and c. Test the effect of the communication tablet (VidaTalk) on psychological symptoms in family caregivers.
