Computer-based communication tool provides effective communication for non-speaking patients: a quasi-experimental study

Abstract

Even though they are conscious, patients who are unable to speak while connected to a mechanical ventilator have serious difficulties in communicating with healthcare staff. This research aimed to determine the effectiveness for patients of a computer-based communication tool (CBCT) and to compare these results with patients using a routine method. This quasi-experimental study was conducted with 90 intubated patients. It was found that 20.0% of the patients using CBCT stated that they had difficulties in communicating, while this rate was 82.2% among patients not using CBCT. Compared with participants in the control group, experimental group patients reported a lower median score for the anxiety levels (23.0 [20.0–39.0], 29.0 [20.0–57.00], p<.001) and higher mean comfort levels (130.2±9.0, 109.6±13.3, p<.001). Positive impacts of the CBCT are its suitability for patients who are dependent upon ventilation for different reasons and their improved ability to communicate effectively.
