The Moore Foundation has recently awarded a grant to Johns Hopkins University Medical Center to pilot the use of iPads for ICU checklists. The leader of the program is Dr. Peter J. Pronovost, who is a pioneer of using checklists in hospitals. Dr. Pronovost recently published an excellent book on this subject "Safe Patients Smart Hospitals", and is the hero in Dr. Atul Gawande's best seller "The Checklist Manifesto".
Now, the checklist, by definition, is a simple list of items that can fit into a single page of paper. Why do we need iPad for something as simple as that? It appears that the iPad will be used to tie together different pieces of technologies the ICU uses -- examples I can think of include access to EHRs, remote access to monitoring devices, decision support, paging to doctors and RRTs, locator of critical equipments etc. All of those are simple checklist items, but the iPad could make them all work together and save precious time in responding to patient events.
