In eight outpatient clinics within Boston's Brigham and Women's Hospital, nurses are now using PDAs to enter data, such as their patient's vital signs and where on a person's body a blood pressure reading was taken from. This information is then sent automatically via their device to the hospital's electronic medical records system. The wireless PDAs are attached to wheeling IV poles outfitted with monitors. Before implementing the system, less than 10% of patient blood pressure data was available in data form in the electronic records system. LINK
