A group of researchers at Vanderbilt University published this study (full text $30) on the impact an electronic whiteboard had on ED operations:

The results indicate that the electronic whiteboard improves the
efficiency of work and communication in the ED. IT solutions may have
great utility in improving provider situational awareness and
distributing workload among ED providers. The results also demonstrate
that IT solutions alone will not solve all problems in the ED. IT
solutions will probably be most effective in improving efficiency and
safety outcomes when paired with human-based interventions, such as
crew resource management. Future studies must investigate team
interaction, workload and situational awareness, and the association of
these factors to patient and provider outcomes.
