MEDICATION ADMINISTRATION PROCESS

Wash hands with soap and water or with waterless hand sanitizer before and after patient contact

Gloves

HAND HYGIENE

Must use at least two patient identifiers whenever administering medications.

Acceptable identifiers may be the person’s name, an assigned identification number, a telephone number, a photograph, or another personal identifier.

If bar code scanning is available, scan the patient’s armband

IDENTIFICATION OF PATIENT

Scan barcodeVerify that this is the correct medicationVerify doseDouble verify

High risk medications (heparin, insulin)Controlled substances

VERIFICATION OF THE MEDICATION

More people die in a given year as a result of

medical errors than from motor vehicle accidents (43,458), breast cancer (42,297), or AIDS (16,516).

Bates, Cullen, Laird, et al. “Incidence of Adverse Drug Events and Potential Adverse Drug Events.” JAMA, 1995, 274, 29-34.

Nationally 2 of every 100 admissions experienced a preventable adverse drug event, resulting in increased hospital costs of $4,700 per admission.

This is $2.8 million annually for a 700-bed teaching hospital.

*Johnson, Carlson, Tucker, & Willette Using BCMA in VA Medical CentersJournal of Healthcare Information Management-Vol 16, No.1

Effect of BCMA*Barcode Medication Administration (BCMA) in VA Medical Centers*:

8,000,000 doses dispensed 549,000 errors prevented 0 documented errors

*Eastern Kansas Health Care System (VA) 1994-2001*:Why barcode medications?

Physician order received Order faxed to Pharmacy Pharmacists edit and verify electronic orders

into patient profile Pharmacy dispenses ordered medications in Bar-

Coded packages Nurse accesses BMCA software on computer

via log on Nurse scans unique patient bar-coded ID band

BCMA Steps

Nurse utilizes two unique patient identifiers to verify armband

Nurse verifies patient profile medications as per order

Nurse scans bar-code on medications Nurse administers medications

BCMA Steps (cont)

•Reduction in medication errors•The FDA estimated that over a 20 year period the number of medication errors would be reduced by 50% and up to 500,000 adverse events would be avoided by utilizing BCMA

(Food and Drug Administration, 2004).•Ease of checking the five rights of medication administration•Automatic MAR creation•Lab results can be displayed at the point of care•Alerts for missed medications

BCMA Advantages:

BCMA Disadvantages:

Estimated to cost $1,799 per bed to implement BCMA, with an additional $1,000 yearly for maintenance

No universally accepted bar codesBar codes that are unable to be scannedEquipment malfunctionOver reliance on BCMA to catch errorsStat medication turnaround time

(ZIH, 2006)

BCMA Workarounds

Over 15 types have been identified that could potentially lead to errors

For example: Nurses override alerts for 4.2 % of patients cared for and for 10.3% of

meds charted

(Karsh, Koppel, Telles, & Wetterneck, 2008)

Require special order from physicianMust be stored in a secure mannerAvoid using home medications unless they are

unavailable from the hospital pharmacyIf using home medications, they must be stored

in and dispensed from the hospital pharmacy only upon positive identification
