I’ve been working with a group here on a Failure Mode and Effects Analysis (FMEA) for our bar coding medication administration project (called MAK –Medication Administration checKing by our vendor, Siemens Medical ). The benefit to implementing such as system is to significantly reduce the number of errors that occur during medication administration in hospitals each year.
While researching the project I have come across several interesting facts. I would like to share them with you here.
A study by Bates in The Journal of the American Medical Association(1) reported the following results from their experiences with adverse drug events (ADEs):
1%Â were fatal (none preventable),
12% were life-threatening,
30% were serious
57% were significant.
Of those ADEs above:
28% were judged preventable.
42% of the life-threatening and serious ADEs were preventable
18% of the significant ADEs were preventable
Of the preventable ADEs:
56% occurred during ordering (i.e. provider’s written order)
34% occurred during administration
6% occurred during transcription
4% occurred during dispensing (i.e. pharmacy)
48% of the ADEs that occurred during the ordering process were caught versus 0% at the administration stage. And that my friends is the key to implementing a bar coding medication administration system. Zero percent of the errors that occur during administration were caught. That is 100% failure.
In regards to why to error occurred(2):
The most common systems failure was in the dissemination of drug knowledge, particularly to physicians, accounting for 29% of errors.
Inadequate availability of patient information, such as the results of laboratory tests, was associated with 18% of errors.
Seven systems failures accounted for 78% of the errors
