In the second phase of the study, 400 2-4 hour time slots will be randomly selected over about a 5-week period for nursing staff and 500 events over a 6-week period for physicians to conduct ethnographic observations during which specific communication events will be recorded and coded. Every effort will be made to minimize interruptions during clinical care. This research has not been done in terms of medication management content in the inpatient setting (non-ICU).
