In late July 2004, a shocking report hit the healthcare news wires that 195,000 deaths in the U.S. could be attributed to hospital errors. This number nearly doubles the Institute of Medicine's (IOM) 1999 study that claimed 98,000 people a year die from what it characterized as preventable medical errors.

HealtGrades, Inc. a Lakewood, CO based company took into account the Medicare records of 50 states and Washington DC over a three year period from 2000 through 2002. Out of 37 million hospitalizations tracked, there were 1.14 million "patient-safety incidents" reported, and "of the total 323,993 deaths among Medicare patients in those years that developed one or more patient-safety incidents, 293,864, or 81% of these deaths were directly attributable to the incidents." Thus, between 2000 and the end of 2002, 1 out of 4 Medicare patients died of a patient-safety related incident. See: http://www.msnbc.msn.com/id/5536730/

In an effort to reduce costly medical errors and increase patient safety, more and more hospitals and health systems have begun to initiate positive patient identification (PPI) strategies which include Bar Code-Enabled Point-of-Care technology (BPOC). BPOC systems, when augmented with sophisticated computer logic, can protect patients from prescription, transcription and dispensing errors. This technology allows for real time confirmation of patient identification, medication, dose, time and route of administration.

HIMSS (Healthcare Information & Management Systems Society) in its 15th Annual Leadership Survey sponsored by Superior Consultant Company and released in June, 2004, reported cost pressures and patient safety issues were the top two business challenges that will have the greatest impact on healthcare over the next two years. It was also reported that the top IT priorities in terms of automated clinical applications were: #1: Electronic Medical Records (EMR); #2: Computer-based Practitioner/Physician Order Entry (CPOE) and # 3: Clinical Information Systems.

As for which healthcare technologies will have the greatest focus over the next two years: high-speed networks, data security, and bar coding garnered the most survey votes from information technology (IT) executives at healthcare provider institutions and vendor organizations across the U.S. The rise of bar coding in importance, as compared to 2003 HIMSS survey results, can probably be attributed to increased industry awareness of the role that bar code technology can play in helping to reduce misidentification errors that ultimately will lower the number of patient-safety-related or Sentinel Events.

Introduction

Regulatory Influences: HIPAA, FDA & JCAHO

The Healthcare Insurance Portability and Accountability Act of 1996 (HIPAA) was the kick start for healthcare institutions to seriously consider bar coding as a means of safeguarding the way they transmit, store, and access protected health information. HIPAA regulations state that a common set of codes must be adopted by healthcare facilities that encompass all medical procedures as part of an electronic exchange of information to increase efficiency and reduce medical errors.

More recently, however, the U.S. Food and Drug Administration (FDA) released its final ruling in February 2004 requiring a linear bar code (that conforms to Unified Code Council "UCC"

specifications) be on many over-the counter and prescription drugs, vaccines, and blood products administered in healthcare settings to help improve patient safety at point-of-care. The Joint Commission on Accreditation of Healthcare Organizations (JCAHO) also views correct specimen labeling and accurate patient ID as cornerstones of their Patient Safety Standards & Guidelines:

■ Use at least two patient identifiers (not including the room #) whenever taking blood

samples or administering medication or blood products.

■ Prior to surgical or invasive procedures, conduct a final verification process.

Positive Patient ID at Point-of-Care & PDC’s Role

The reduction of medication errors at point-of-care is the primary goal of many healthcare institutions that have opted to automate their medication administration processes: e-MAR (electronic medication administration). Nearly one third of the medication administration errors that have been cited as the cause of ADE (Adverse Drug Events) occur at bedside and only 2% are caught. Clinical research released in September of 2002 concluded that "healthcare facilities are experiencing as many as 1 error per every 5 administered," leaving a huge gap in acceptable patient safety standards. See: www.bridgemedical.com/pdf/whitepaper_barcode.pdf

To ensure positive patient identification, successful bar code implementation integrates the responsibilities of healthcare professionals in Admissions, Pharmacy, Laboratory, Blood Bank, Emergency and other patient care departments. Healthcare personnel in Patient Safety, Quality Control, Risk Management, and Information Technology are also involved in the development and implementation of Bar Code Point-of-Care (BPOC) systems. To that end, Precision Dynamics

Through the entire patient point-of-care process, the ultimate goal is to provide quality healthcare to each patient and to ensure the accurate administration of the five rights: Right Patient, Right Drug, Right Dose, Right Time and Right Route of Administration.

This reference guide is for all healthcare managers and practioners who are evaluating bar code wristband or bar code label systems to ensure positive patient identification in their facility. We hope this information will assist you in selecting the best solution to meet your needs. Inside you will find a summary of Precision Dynamics' portfolio of bar code solution options including the advantages and disadvantages of each. The three areas of focus will be:

■ Thermal Printing Wristband Solutions

■ Adhesive Label Wristband Solutions

■ Laser Printing Wristband & Label Solutions

Regardless of which option you select, we at Precision Dynamics want to go on record to urge you to choose a solution which offers you optimal security with a positive tamper-evident closure in a wristband, along with optimal scanability and freedom from smearing, moisture or other vulnerabilities in a label. The American Hospital Association (AHA) calls for a

"tamperproof, non-transferable identification band…that minimizes the possibility that identifying data can be lost or transferred from one patient to another." (See: the American Hospital

Association Management Advisory: Identification of Newborns & Other Patients, 1992.) All of Precision Dynamics media products meet these important criteria for patient safety and have a long history of successful use in the healthcare field.

RFID represents the next advanced step in positive patient identification after bar coding. PDC

pioneered the development of the Smart Band®_{RFID Wristband System in 2000 and continues to}

lead the way in Auto ID. PDC RFID solutions ensure the integrity of information between patient, host device, and/or hospital information center. Unlike bar code, RFID’s non-line-of-site data transmission can be read through and around the human body, clothing, bed coverings, and non-metallic materials. Furthermore, RFID wristband solutions help to ensure that the "Five Rights of Medications Safety" are achieved, facilitating real-time confirmation of the Right Patient, Drug, Dose, Route, and Time.

D

Deemmaanndd PPrriinntteerr - A printer capable of creating individual documents one at a time, as needed D

Doott MMaattrriixx PPrriinnttiinngg - A print technology that employs several needles which are evenly spaced across a moveable horizontal shuttle which oscillates back and forth as the paper advances. Dot matrix printers print a bar code by creating overlapping adjacent dots to produce

approximations of a straight edge line. Prints low to medium density bar codes that may not meet certain end-user guidelines. The dot size on the matrix printer limits the narrow element size and density of the bar code. Continuous ribbon re-use on dot matrix printers requires continuous monitoring of ribbon condition to ensure adequate bar code contrast - Ribbon ink that has become exhausted can produce an image that is inadequate for scanning. Ink saturated ribbon can result in paper "bleed" which can cause image distortion. Dot matrix printers are modified line printers that are most frequently used for printing batches of large labels with low density bar codes. Printing of single, individualized labels results in significant waste. The design of the matrix printer's print carriage, sitting far below the media, also does not enable one to adequately maximize one's label space.

D

Doott SSiizzee ((PPrriinntteerr)) - The size of the printed dot on a substrate in a matrix or line to form

characters. Minimum dot size is determined by the size of the thermal element of the print head being used by the thermal printer. Dot size determines the X dimension. The X dimension is always a simple multiple of the dot size.

D

Doott SSiizzee ((SSccaannnneerr)) - The diameter of the beam of light projected by the scanner used to read a bar code symbol. The scanner dot size should be no larger than the X dimension of the bar code symbol. D

Diirreecctt TThheerrmmaall PPrriinntt - (DT) Direct thermal printing is an old technology originally designed for low cost copiers and fax machines. It has since been transformed into a highly successful technology for bar coding. The thermal print head is typically a long linear array of tiny resistive heating elements (100-300/inch) arranged perpendicular to the paper flow. Each thermal print head element locally heats an area on the chemically coated paper directly under the print element. This induces a chemical reaction which causes a dot to form in that area. The image is formed by building it from dot rows as the media passes underneath the active edge of the print head. Direct thermal printing is an excellent choice for many bar code labeling applications. DT printers provide

LLaasseerr SSccaannnneerr - An optical bar code reading device using a low-energy laser light beam as its source of illumination.

LLaasseerr PPrriinnttiinngg - The laser printer works much like a photocopier projecting controlled streams of ions onto the surface of a print drum resulting in a charged image. The charged image then selectively attracts toner particles - transferring the image onto the paper substrate (media) by means of pressure. The pressure from the print head and drum then fuse the image to the paper - creating the image. A laser printed label is only as durable as a photocopy of paper. They commonly cannot produce chemical or water resistant labels. Laser printer labeling adhesives must be carefully selected to ensure stability under the heat and pressure of the fuser. Laser printers are not well suited for industrial labeling applications or individual product labeling applications. Compatible toners for thermal printing applications are, often times, lacking. Cost of toner is significant for barcode printing - 15-30% black for bar code print versus 5% black for word processing print - 6 x the cost for barcoding using laser when compared to direct thermal or thermal transfer!

Print - Thermal transfer printers use the same basic technology as direct thermal printers, but with the elimination of chemically-coated media in favor of a non-sensitized face stock and a special inked ribbon. A durable polyester ribbon film coated with a dry thermal transfer ink is placed between the thermal printhead and label. The thermal print head is used to melt the ink onto the label surface, where it cools and anchors to the media surface. The polyester ribbon is then peeled away, leaving behind a stable, passive image. Consistent / sharp edge bar code print capability - with durable long-life and archival image stability. Clean, quiet, compact operation Batch or individual label print capability. Low cost / low maintenance compared to comparable technologies. Maximum readability and IR scanability. High contrast text, graphic and barcode print capability. Durable for operation joint office / industrial applications.

Throughput - refers to the average length of label stock that a printer can process and print in a given amount of time. Throughput differs from print speed in that throughput includes the label transmission, formatting and printing times.
