Ongoing evaluation of ease-of-use and usefulness of wireless tablet computers within an ambulatory care unit.

: This ongoing research is to assess user acceptance of wireless convertible tablet portable computers in their support of patient care within the clinic environment and to determine their impact on workload reduction for the information staff. A previous publication described our initial experience with a limited wireless environment. There, we tested the premise that wireless convertible tablet computers were equivalent to desktop computers in their support of user tasks. Feedback from users demonstrated that convertible tablet computers were not able to replace desktop computers. Poor network access was a weakness as well as the "cognitive overhead" encountered due to technical problems. This paper describes our further experience with a centre-wide wireless implementation while using a new wireless device. The new tablets, which have some unique functions that existing desktop computers do not provide, have been well received by the clinicians.
