What nurses want: diffusion of an innovation.

We investigated the usability of personal digital assistants (PDAs) to improve research utilization and timely access to electronic practice information to assist in clinical decisions. Nurses used a decision support tool on a PDA to collect point-of-care outcomes data. Follow-up interviews documented usability. Nurses liked the portability and size of the PDA, as well as ease of use of the PDA software. Electronic decision support tools at point of care have the potential to improve nurses' research utilization and quality of care.
