A recent survey of health care organizations found that almost 30 percent have automated the documentation process with a computer-based patient record (Perreault and Wiederhold, 1990). Research is needed to determine the impact of computerized information systems on quality of care and the nurses’ perceptions on the security (accuracy and confidentiality) of data. The Nurse’s Perception of Charting Accuracy and Confidentiality instrument (NPCAC) is being developed to identify these variables. The purpose of this study is to identify the pertinent literature, develop the initial questions, and to begin to validate this instrument.
