• Its also a automatic input device because it is linked to a database on a computer and so the user doesn’t have to manually use the input device. i.e. the barcode reader automatically scans the code and the database on the computer identifies the item. • Normally barcode readers are used in supermarkets or any shops.
The clinical lab and pathology departments frequently use barcodes to track specimens and convey configuration data to analyzers in a machine-readable format. Barcodes are frequently included in the HIS order-entry system’s printed orders. Many of these barcodes are then used within various departments for workflows of modest complexity.
Vendors have little incentive to shoulder the cost of adopting barcodes if customers have no scanners with which to read them. Likewise, providers have no reason to buy scanners when there are no barcodes to be read.
The risks and advantages offered by barcodes have been well known for a decade or more (Leape et al., 1995; Brennan et al., 1991; Low & Belcher, 2002). The concept of barcodes goes back to 1948, and the first scanner was installed in a Cincinnati Kroger grocery store in 1972 (Reynolds, n.d.).
The concept of barcodes goes back to 1948, and the first scanner was installed in a Cincinnati Kroger grocery store in 1972 (Reynolds, n.d.). In spite of the fact that the needs are well understood and the technology mature, barcode technology adoption in hospitals has yet to meet the expectation of many in the industry.
Vendors have underestimated the challenges of capturing and automating workflow, as have most hospitals. According to Igor Nesterenko, Alaris product manager at Cardinal Health, “Most early adopter hospitals try to figure out workflow after purchasing a system, as they go through implementation.”.
