Telling
Twins Apart
Two PSRS
reporters described situations of drug administration events
associated with close similarity in drug names and in labeling/packaging.
In May 2001, Joint Commission issued a Sentinel Event Alert on look-alike,
sound-alike drug names. Two months earlier the US Pharmacopeia
released a list of over seven hundred confusing drug name
sets. The first reporter had another set to add to this list:
- [An]
order was correctly entered for docetaxel (for metastatic
breast cancer) but misread by [the] pharmacist as Doxil,
[a] more commonly used chemotherapeutic agent at the hospital.
Independent
verification of accurate drug dispensing by another pharmacist
was bypassed:
- Second
check by another pharmacist was not done. [That person]
was out of pharmacy at the time and patient was waiting
to receive prescribed medication.
- Both
administering nurse and verifying nurse checked the order
and dose and read as "OK"... The verifying nurse
for a moment thought it was different but it was so close
she thought it must be the same and let it go.
The second
pharmacist discovered the error shortly after the medication
was given. The reporter summed up the event:
- The
similarity of the drugs was a contributing factor. However,
failure to follow the entire process of verification led
to bypassing barriers that were in place, that if followed
would have prevented the administration of the wrong drug.
Another
PSRS report describes the challenge of differentiating between
multidose vials of Haldol and Prolixin.
- The
packages and vial labels are the same color, very slight
difference in shade, and print the same for both medications.
A nursing
leader took action to increase staff awareness:
- The
charge RN has placed numerous posters in the med rooms regarding
the Haldol/Prolixin look-alike packages and vials. Many
staff nurses have thanked the charge RN for the poster reminders,
since they had drawn up the wrong meds and during the double-checking...
caught the potential error.
- Near
miss event... easily corrected with color design change
to multidose vial [by pharmaceutical manufacturer].
A
Guessing Game
According
to the Journal of the Medical Informatics Association (Sep-Oct
2001), physician satisfaction with computerized order entry
systems is strongly correlated with the ability to perform
tasks in a straightforward manner. A clinician described how
lack of accurate formulary information in CPRS affects efficiency:
- The
CPRS program does show a formulary-type display of available
medications including strengths; however, the facility pharmacy
inventory does not always stock the dosages displayed in
the CPRS program... Current drug prescribing process creates
confusion because the clinician often does not know the
strength of drugs currently available in the pharmacy. If
the clinician does not know the strength, he cannot know
with certainty the amount of drug to be issued.
The reporter
added that the lack of an updated formulary affects others
in the system:
- Usually
the pharmacist will try to contact the clinician but if
that cannot happen [they] will make the best decision [they]
can. This often results in inadequate amounts of drug being
issued, which leads to phone calls and extra trips back
to clinic.
Reading
the Fine Print
Ongoing
research examines methods of labeling and packaging medications
to improve drug therapy compliance in older people, taking
into account their functional limitations. Examples are found
in Drugs & Aging (Jan 1998) and Ergonomics (March 2003).
A PSRS reporter is equally concerned with helping veterans
overcome these challenges:
- Our
patient population is primarily elderly and their vision
is not always 100%. Our prescription bottles have writing
that is very small and hard to read, even for those with
good eyesight. Also, the ink print on the prescriptions
sometimes wears off which makes it even more difficult to
read.
Other
adverse outcomes for patients could include:
- [Patients]
may not be taking their medications correctly or even taking
the correct medications.
The reporter
suggested:
- Developing
a labeling system that highlights the important information,
using larger print and bolding certain parts of the label.
- Attach
another label (i.e. flag the bottle) with a large print
of the drug name only so patients would know which drug
they have... This would at least make it easy for them to
identify their medications.
- Cover
labels with transparent tape to protect printing.
Strong
Things Come in Small Packages
A PSRS
reporter detailed the outcome of a medication dispensing event:
- Hospital
pharmacy mailed out medication to the wrong patient. Recipient
took medication and became toxic, requiring hospitalization
and dialysis.
The next
time, the patient was prepared:
- One
month later, same pharmacy sends wrong medication to the
same patient who by now realizes not to trust the
medications he is sent. He brings the incorrect medications
to his primary doctor.
A
Drip In Time Could Have Saved Nine
As many
as 50% of postoperative patients are undermedicated and suffer
unrelieved pain, according to the American Society of PeriAnesthesia
Nurses (Feb 2002). In the VA, the technologies of PCA (patient
controlled analgesia), BCMA and CPRS can work together to
maximize patient comfort. However, this depends upon effective
communication and coordination, especially between departments.
A post-surgical
ward nurse described to PSRS what happened when those systems
did not talk to each other. Fifteen minutes after arrival
from the recovery room, a patient summoned the nurse:
- [The
patient] called out to RN to say he was in "severe"
pain. ("12/10"). After checking BCMA for PRN meds,
I found he had no PRN pain meds ordered. I then checked
patient orders in CPRS and saw that PCA morphine sulfate
had been ordered for patient for post-op pain [an hour earlier].
The nurse
telephoned the physician, who ordered a morphine sulfate bolus
to initiate immediate pain relief.
- Patient
given morphine sulfate IV push and PCA was initiated [two
hours after order written]. OR and PACU should initiate
PCA prior to transfer to floor for control of immediate
post-op pain.
