Evaluation of Mobile Tablet Computers for Use in the Veterans Health Administration

The Veterans Health Administration (VHA) within the Department of Veterans Affairs (VA) was interested in determining how mobile tablets may be perceived by clinicians for use in clinical settings. Therefore, we conducted an evaluation to assess how performance might differ between two devices and to gather feedback on device use. We conducted a within-subject comparison with 32 clinicians involving a usability test and two questionnaires. Qualitative data was organized around eight themes: facilitators and barriers to tablet use, observations of physical use, device specific advantages and disadvantages, and the Patient Viewer mobile application. Clinicians envisioned many facilitators to tablet use, but also voiced some concerns. Participants rated one device significantly better than the other for questionnaire items related to ‘Access and Efficiency’, ‘Introduction into the Clinical Environment’, ‘Usability and Usefulness’, and ‘Desire to Use’. Results can be used by mobile health app developers, healthcare organizations considering device purchases, and researchers conducting studies on tablets to inform respective work.
