Butler R, et al. - Experts sought to accurately measure the time physicians, nurses, and critical support staff in a medical intensive care unit spend in direct patient contact using a network of stationary and wearable mote-based sensors to electronically record location and contacts among healthcare workers and patients. Findings suggested that physicians, nurses, and critical support staff spend very little of their time in direct patient contact in an intensive care unit setting. It was not surprising to note that compared to the physicians, nurses spend far more time with patients. Also, more than twice as much time of physicians was spent in the physician workroom (where electronic medical record review and documentation occurs) than the time they spend with all of their patients combined.
