A primary difference between radiofrequency identification (RFID) and barcode is that RFID has great read range. While the read range for barcode ranges from inches to a few feet, passive ultra-high frequency (UHF) RFID ranges up to 40 feet if readers are fixed or up to 20 feet if readers are handheld. Active RFID has a read range hundreds of feet. Active RFID tags are battery powered and emit a signal while passive RFID tags require activation by a reader.
“If we cannot name it, we cannot control it, finance it, teach it, research it or put it into public policy.”
(When nurses can describe what they do in terms that the public and others can understand, they begin measuring it, evaluating it, and validating its impact on the nation’s health, research, and public policy. )
–By Lang, N. 1993
The focus of traditional clinical nurse is taking care of patients. Therefore, historically, computers in nursing were seen as to manage patient care data, to analysis data into information in order to monitor quality of care, and eventually help evaluate patient outcomes. With the commonly used of networks, clinicians are now using computers for communications via internet, obtain and exchange information and resources, and interact within multidiscipline and as well as interacting with patients and patient family members. In the meantime, nurses found themselves in the mid of using computer systems for patient care planning, system managing, policy making, nursing education, and nursing researches.
