Bar Code and Frequency

In recent years, routine “data collection” and its tools have been groundbreaking, including tools such as bar codes, magnetic stripe cards, readers and radio ID tools, are utilized for purpose in a diversity of healthcare applications. The bar code compilation tools are employed an ‘eye bank’ tracking ‘time-critical donor tissue.’

Routine data compilation tools, more precisely the bar code technology, were employed in hospitals. The employ of the bar code purposely was used to improve patient care excellence.

Bar codes particularly were employed for prescription labeling, inpatient identification, inventory control, and specimen recognition. In 1993, Picker made a report that Lackland Air Base Hospital employed PDF417 bar codes. Picker claimed that the codes were positioned on hospital employees ID cards for emergency room registration. The bar codes PDF417 incorporated two-dimensional codes which it interpretation symbolized information outweighing traditional one-dimensional codes.

Within the body of the PDF417, bar code is information relating to extensive medical and personnel identification. The 58,000 patients utilizing the hospital each year now can expect accuracy and quick response, as well as quick data retrieval from the code alone.

The Mayo Clinic utilized the bar code, placing the codes on the patients’ wrist to identify each patient, said Bellows in the 1994.

The wristband and data compilation scheme is an assurance that blood products are giving to the patients properly when needed, and that safety is guaranteed through accuracy tracking and identification of patient care by use of the code.

The central unit processing tools and its use in the emergency department at a larger angle provided a means for nurses to schedule, analyze the clinical information system said Walrath in 1983. Specifically speaking, “the field of medical informatics” study employs the science and technology information, studying in a larger angle of medical applications.

In 1995, Miller and Jones stated that the employ of bar codes and the tracking scheme of patients made it easy to manage hospital beds. Via bar code, the patients were tracked to a room from admission and continued tracking through discharge. The notion made it convenient for housekeeping to ready the hospital rooms for incoming, since the code made available which rooms were in use and which rooms were available.

The bar code system eliminated the considerable failure in the hospital administration for long-term patient and for residency in inpatient hospital rooms. The information is the closest related to the work in literature to a patient tracking and control scheme. Still, no author has followed up on this publication.

The motive to meet customer expectations and how the patients deem how the hospital should be running, became an endeavor, thus the code gave new light. Thus, the concept gave way to a cycle of improvement, while embracing the changes made by the department of emergency management, at the same time improving quality of patient care. The code also allowed survival for the hospitals and its emergency region, including the contained links within its region.

One of the newer developments known as radio frequency naming is another of the data collection technology that has brought for a broader range of usage. The three components of the frequency include antennae, tags, and readers. Thus, the reader initiates a question singling the tag through and energy burst which goes out in the form of radio waves signaling through a channel and sent from the antenna.

As a result of the frequency, low passive transponders embed within the tag. The antenna signals transmit a charge to transponder, sending in a matter of milliseconds. In turn, the transponder returns the signals carrying the information and is captured by the antenna and interpreted by the reader.

Similar to the Mainframe, information is sent to a host central processing unit sending to a standard PC connection or else to a user interface. Radio frequency identification schemes are flexible which preferred in numerous environments, which other technology routine data collections cannot match.

Data collection would be hazard to humans, if it could do what the frequency do, and that is the frequency is useful in dark, dirty and dusty conditions.

The radio frequency identification scheme does not require “line-of-light” for reading, or else collection of data, thus this is the advance the frequency has over common data collection. The capabilities of the frequency “in which time or other” restrain make it unfeasible for humans to obtain data physically.

Clinicians in emergency rooms labor concerning their time with the patients, yet do not have the time to collect auxiliary management information, thus the evidence is seen in the prior paragraph. By reason of the “unobtrusiveness” and the accurate collection of data with the frequency, the scheme was selected for the data collection in an experimental patient tracking and control system, which was shaped in this particular research.
