Patient record is the repository of data describing the patient care process. It is the center of many diverging aims such as monitoring the care delivery process for a given patient to the recycling of care data for health statistics, accounting and billing. The nursing care process, as an example of the problem solving paradigm applied to health care plays a key role in the nursing activity. Its architecture is apparently quite compatible with emerging European standards for Electronic Healthcare Records (EHCR). A detailed study of nursing modules implemented in various existing or recently developed patient information systems will give critical indications for the integration of nursing data in a standardized architecture of electronic healthcare records.
