Abstract: Failure to recognize changes in a patient’s clinical condition is a barrier to the effectiveness of CCRT outreach programs. The development of a vital signs capture and decision system could alert care providers and CCRTs when a patient’s clinical condition deteriorates. However, point-of-care vital signs capture and documentation is often problematic in clinical practice. Ethnographic research was conducted to understand the difficulties of replacing pen and paper charts and barriers to electronic nursing documentation systems. Analysis of workflows directed the design of two solutions; 1) Apple iPhone facilitated manual vital signs entry, 2) Motorola MC55 enabled automatic data capturing from physiological monitors. Nurses participated in high-fidelity usability testing, comparing the traditional method of paper documentation with the two electronic solutions. As a result of user-centered design process, both solutions were comparable to the efficiency of paper methods, were found acceptable to nurses, and could be successfully incorporated into current workflows.
