Computer-Based Communication Tool Provides Effective Communication for Non-speaking Patients: A Quasi-experimental Study

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.
