title: Effects of a computerized cardiac teletriage decision support system on nurse performance: results of a controlled human factors experiment using a mid-fidelity prototype.
abstract: A gap exists in cardiac care between known best practices and the actual level of care administered. To help bridge this gap, a proof of concept interface for a PDA-based decision support system (DSS) was designed for cardiac care nurses engaged in teletriage. This interface was developed through a user-centered design process. Quality of assessment, quality of recommendations, and number of questions asked were measured. Cardiac floor nurses' assessment quality performance, but not their recommendation quality performance, improved with the DSS. Nurses asked more questions with the DSS than without it, and these additional questions were predominantly classifiable as essential or beneficial to a good assessment. The average participant satisfaction score with the DSS was above neutral.
