Usability Testing of an iPad Communication Application for Mechanically Ventilated Patients

Patient communication challenges during mechanical ventilation can negatively impact symptom management and psychological recovery. Alternative communication (AC) aids have the potential to improve mechanically ventilated (MV) patient experiences.

This study evaluated the feasibility and usability of a communication application on a tablet (iPad).

A single-group pilot study was guided by the augmentative and alternative communication acceptance model. We recruited patients from 1 medical intensive care unit. Existing communication application software (Proloquo2Go) was tailored to MV patients' needs. Usability testing included patient communication of 5 messages with data collected on success, message completion time, and patient feedback.

Ten patients with a mean age of 50 years (SD, 16.7) were enrolled. Of the 7 patients able to complete usability testing, 85.7% found the device easy to use, and 100% wanted the iPad available for their use when on the ventilator. Three patients were extubated immediately after usability testing. Two patients preferred other modes of communication (writing). Two patients used the iPad as their primary mode of communication during the remainder of their time on the ventilator. Nurse feedback on the communication application was positive.

Tablet-based communication applications can be successfully used by MV patients and should be considered as 1 tool to support effective patient communication during mechanical ventilation. Future research is needed to identify which patients may be most likely to benefit from the availability of these devices.
