A Lightweight Approach to Barcode Medication Administration

  1. 1. A Lightweight Approach to Barcode Medication Administration The Paper’s Authors: Vadim Zimin Jeruel Fernandes Annie Wang Joseph Ogunyebi Rob Ticehurst* Dr David Parry *Auckland District Health Board Presented by: Vadim Zimin
  2. 2. Blood Transfusion: Bedside Checking • Identify the patient • Complete the loop • A second person performs the same checking process • There must be no discrepancies
  3. 3. Medication Administration on a Ward The procedure • Medications prescribed for each patient on a paper chart • Nurse selects required medicines from shelving in medication room • Nurse administers to the patient Several points • Only one patients medicines should be prepared at a time • Repetitive task • Nurses create workarounds = error-potential
  4. 4. Where does it go wrong? • Current checks are wholly reliant on humans • Humans make mistakes • All hospitals will have reports of “wrong patient” errors from blood products and medicines • The consequences of these errors are devastating for all involved – patient and healthcare professional • Simply telling someone to do better is not an effective nor sustaining intervention • Can we use technology to make it harder for the human to get it wrong?
  5. 5. Literature Review Hassink, J., M. Jansen, et al. (2012). "Effects of bar code-assisted medication administration (BCMA) on frequency, type and severity of medication administration errors: a review of the literature." European Journal of Hospital PharmacyScience and Practice 19(5): 489-494. • Summarises 11 studies • Reviewed literature manly supports the idea that BCMA helps to reduce proportion of medication errors • Use of barcode technologies do not increase time spent by nurses for medication administration
  6. 6. Literature Review Chan, J. C. W., J. Lau, et al. (2004). “Use of an electronic barcode system for patient identification during blood transfusion: 3-year experience in a regional hospital.” Hong Kong Medical Journal 10(3): 166. • Three-year study in a Hong Kong regional hospital • Scan-and-print device was used to verify and document patients’ identity • No incidents occurred with 41 000 blood sampling procedures and administration of 27 000 units of blood • Barcode system was effective in reducing human error related to bedside transfusion procedures
  7. 7. Literature Review Van Onzenoort, H. A., A. van de Plas, et al. (2008). "Factors influencing bar-code verification by nurses during medication administration in a Dutch hospital." American Journal of Health-System Pharmacy 65(7): 644-648. • Electronic records were compared to number of prescribed medication administrations • Rate of nurses’ noncompliance – about half of cases • Five most common reasons: • • • • • Issues with scanning barcodes Delay of software Not knowing that medication had barcode label Lack of time Medication administration prior prescription
  8. 8. The Core Function Scan and compare barcodes The same Different
  9. 9. Implementation and Testing Implementation • Mobile-based application • BYOD Testing • Tested on an iPod 4 and iPhone 4S • Barcodes are scanned efficiently • iPod 4 lacks auto-focus Limitations • Was no pilot test • Smartphones not yet available for all nurses
  10. 10. Future Work Portable terminals • Are mobile computers with embedded OS and built-in barcode scanner Proof of concept • Application developed and tested with portable terminal What is next? • Pilot on a ward at Auckland Hospital
  11. 11. Key Points • Simple implementation • Barcodes are already available on patient identifier label • Significant potential to improve patient safety • Supporting evidence in published literature • In-demand
