Patient Safety
Manic
for
Medication Safety
Bar codes and drug information databases are helping to reduce
medication errors
By Richard R. Rogoski, Contributing Editor
The tragic deaths last September of three premature
newborns who were mistakenly given an adult dose of heparin in an
Indianapolis hospital did more than just make headlines. It also served
as a stark reminder that too few healthcare organizations have in place
adequate safeguards that can prevent medication errors.
Those who give more than lip service to issues of patient safety know
that they not only have to invest in new technologies, but they also
need to regularly review and update their policies and procedures
pertaining to the ordering and distribution of medications. While errors
can occur at any point along the route, from the physician’s initial
order, to the filling of carts in the pharmacy, to the administration of
meds by nurses at the bedside, it is at the point of care that
clinicians can establish a last line of defense.
Not surprisingly, implementation of bar-code technology at the bedside
is proving to be an effective way to reduce most medication errors. “The
benefit is that it’s at the end of the pipeline and most likely is going
to catch everything coming down that pipeline,” says Jim Douglas, R.N.,
clinical systems administrator at Northern Michigan Hospital in
Petoskey, Mich. Douglas says that in 2006 alone, the hospital reduced
medication errors by 5,744 and prevented 400 serious medical errors,
including two that would most likely have been fatal. Since beginning
the implementation of the Cerner Bridge Medication Administration
point-of-care technology in 1998, more than 21,000 medication errors and
a total of five fatalities have been avoided.
Bar Coding for Safety
At 243 beds, Northern Michigan Hospital has about 120 physicians with
privileges, 450 registered nurses and 15 pharmacists. But as is the case
with most hospitals, the hand-off of patient information during a normal
shift change can be sketchy at best. To ensure that nurses coming on to
the floor are apprised of each patient’s status and any medications
already administered, the Joint Commission on Accreditation of
Healthcare Organizations mandated hospitals establish standards for
effective shift transfer communication.
One of the most serious oversights has always involved the amount of
drugs being administered and the time frame during which they should be
given, says Douglas. This often involves pain management drugs that can
be given near the end of one shift, and then administered again at the
beginning of the next shift if the patient is still in pain.
But another common overdose involves insulin. “Forty percent to 60
percent of patients in most hospitals are on insulin, which reflects the
diabetes epidemic in this country,” says Douglas. Here again, he says,
is where confusion at shift change—a misread order, or a case where “the
L.P.N. gave it, but didn’t tell the R.N.”—can have dire consequences.
Since the point-of-care bar-code scanning system alerts the nurse as to
all previously administered medications based on the five rights (right
patient, right medication, right dose, right time and right route),
these kinds of overdoses are avoided. In fact, according to Douglas, 176
insulin-related errors, including 69 that were considered serious
errors, were prevented in 2006. In addition, from July 2006 to the end
of the year, more than 102 sound-alike errors also were avoided.
The move to a point-of-care bar-code solution proved to be a logical
next step for this hospital. “We had done everything we could do in a
paper world to reduce medication errors,” Douglas says.
At a time when few vendors offered this type of technology, Northern
Michigan Hospital purchased the bar-code scanning system from Solana
Beach, Calif.-based Bridge Medical Inc., which was subsequently acquired
by Kansas City, Mo.-based Cerner Corp. It took about two years before
the system was ready to roll out at Northern Michigan Hospital because
interfaces had to be written, medications had to be bar coded and nurses
had to become familiar with a new way of administering meds. When the
system finally went live on Halloween 2001, Douglas says, “Some nurses
thought it was a treat, while others thought it was a trick.”
Smoothing Human/Technology Interaction
and Integration
Probably the biggest challenge was getting nurses who had never
interacted with a computer to start interacting with a computer all the
time. “We tried to get them to use the computer to look at the most
pertinent information,” says Douglas. After hours of hands-on training
and then actual use of the system, the nurses began to see the benefits
of bar coding, although some still felt that the scanning process added
another step and would take more time. “It took about two years to move
from ‘Why would I scan?’ to ‘Why wouldn’t I scan?’” Nurses were told
that while scanning might take a little longer at the front end, in the
long run it might save time because they wouldn’t be filling out as many
occurrence reports for medication errors and caring for overdosed
patients.
Systems integration also posed a challenge. Initially the hospital had
to write interfaces to the pharmacy’s information system, which emanated
from another supplier, but last spring the pharmacy converted over to
Cerner’s Millennium PharmNet. Since pharmacists now have access to the
wireless, Web-based bedside scanning system from workstations in the
pharmacy, they can see exactly what time and what dosage of a medication
was given to any patient. Because the data is in real-time, dosing
changes can be made before the next scheduled dose is to be
administered.
Obviously, this point-of-care solution has dramatically reduced
medication errors at Northern Michigan Hospital. But, it also has been a
cost-effective solution. Serious medical errors could result in a
patient spending one or more additional days in the hospital, which
hospital administrators have estimated at about $2,600 per day. Less
serious errors can cost about $10 each in labor which, according to
Douglas, is based on the time it takes to “package up a wrong dose, take
it back to the pharmacy and get the right dose back into the nurse’s
hand.” Given the possible expenditures for extra patient days and labor
costs, the hospital estimates it will have saved more than $1 million in
2006.
Improving on an Already Good Patient
Safety Record
When it comes to getting drugs from the pharmacy to the nurse in the
safest and most efficient manner, bar-code technology and automated
devices are playing a larger role. Chambersburg Hospital in
Chambersburg, Pa. is a not-for-profit, acute care hospital with 247 beds
and a medical staff of 169. It also has a staff of eight full-time
pharmacists, two full-time pharmacy managers, five full-time pharmacy
technicians and six part-time pharmacy technicians.
David Grant, R.Ph, M.B.A., director of pharmacy and respiratory care,
says that in February 2005, through a partnership between the pharmacy
and information services departments, the hospital implemented an
automatic medication storage and retrieval system. It also implemented
an oral solid repackaging system from Mountain View, Calif.-based
Omnicell Inc. and began the process of implementing an eMAR/BMV
(Electronic Medication Administration Record/Bedside Medication
Verification) system from Westwood, Mass.-based MEDITECH in April 2006.
The combination of the two systems reduced the time it takes to fill
medication carts, reduced dispensing errors and improved overall safety
at the bedside. “Our error rates were within industry standards to begin
with,” says Grant. “However, our reported error rate in January 2006 was
0.05 percent, with 12 percent of those being dispensing. As of
September, our reported error rate was 0.03 percent, with 3 percent of
those being dispensing on total monthly doses that average 110,000.”
Since the bulk of the eMAR/BMV processes rollout was recently completed,
the impact has not been fully realized, he notes.
At the heart of the new pharmacy system is the Omnicell WorkFlowRX,
which integrates an automated storage and retrieval carousel (PharmacyCentral)
with a tablet/capsule repackaging device (SafetyPak). The automated and
password-protected carousel system has 20 levels from which meds can be
selected. The repackaging system, which has a footprint of only 25
square feet, can handle up to 500 different tablets or capsules. By
integrating these systems with the OmniRx medication dispensing
cabinets, the pharmacist is better able to ensure that the right
medication will get to the right patient. “Whenever a pharmacist enters
an order, it shows up on a picking queue so the technician is directed
to the right level,” Grant explains.
A No-Paper Cart Fill
Because the carousel revolves automatically, the drugs come to the
technician instead of the technician having to hunt for the drugs. This
has made filling carts more accurate and efficient. “Our cart fills used
to take 15 to 18 man-hours,” says Grant. Since it used to be a
paper-based process, each and every medication had to be picked by hand
and placed in the patient carts.
For a while, paper lists were still used. But when everyone felt
comfortable with the automated system, the pharmacy went forward with at
least a one-day trial and initiated a day with a no-paper cart fill. “We
have not looked back since,” says Grant. Because carts are delivered at
3 p.m., the trial cart fill began at noon. In an hour and a half, the
job was complete. Grant says that the average time still runs between 90
minutes and two hours. In addition, he says, “Our drug costs per patient
day have declined, allowing us to reduce our budget by 7 percent.”
The new system also has allowed the pharmacy to better manage its
inventory because it tracks the medications used against the inventory
and indicates when supplies are low. “We create a suggested order
everyday at noon and it’s automatically uploaded to our wholesaler,”
Grant says.
Admittedly, there were some challenges in rolling out this pharmacy
system. The biggest headache that affected both the carousel system and,
ultimately, the eMAR system, revolved around bar codes. “The FDA rule
did not enforce narrow standards for bar codes on pharmaceuticals,”
Grant says. Also, the rule fell short in enforcing that each
tablet/capsule had to have a bar code from the manufacturer. “We had to
find a way to apply our own bar codes efficiently. By using SafetyPak,
Chambersburg Hospital has been able to do 85 percent of its own bar
coding of oral solids,” Grant says.
e-Prescribing for Safety
Having a patient’s medication history and clinically relevant drug
information at your fingertips can dramatically reduce medication errors
even before an order is written. For Gregory James, D.O., M.P.H.,
medical director of Sun Coast Family Care Center in Largo, Fla., a new
hand-held solution not only provides him with vital information, but
also wireless e-prescribing capabilities.
Developed by Tampa, Fla.-based Gold Standard Inc. and available through
Informed Decisions LLC, a subsidiary of Gold Standard, the eMPOWERx uses
a pocket PC/PCS phone to provide the clinician with preferred drug lists
or formularies; real-time, patient-specific prescription histories;
medication alerts for interactions, allergies and other health drug
issues; relevant drug information; and, an interaction reporting tool
from Clinical Pharmacology, Gold Standard’s electronic drug information
and medication management resource. Because it utilizes a secure
wireless network, prescriptions can be sent directly from the
point-of-care to the pharmacy.
As a Doctor of Osteopathic Medicine, James has the same prescribing
rights as any M.D. and eMPOWERx enables him to select the correct drugs
for his patients. Getting between 8,000 and 10,000 patient visits per
year, Sun Coast Family Care Center is owned and operated by Sun Coast
Hospital in Largo, where James also serves as the Family Practice
Residency Program Director. The nonprofit, 45-year-old hospital is
licensed for 200 beds, and James’ clinic operates primarily as a
teaching site for interns and residents. Interestingly, James says about
30 percent to 40 percent of his patients are on Medicaid and between 25
percent and 30 percent are on Medicare.
The fact that so many of these patients are on Medicaid actually became
a plus for the successful operation of eMPOWERx in this practice. “Every
time a Medicaid patient fills a prescription, their data gets entered
into the system,” James says. “As long as they use their Medicaid card
when filling a prescription, their medication history can be accessed
via eMPOWERx.” This is an added benefit since the system also alerts the
doctor when it is time to refill a patient’s prescription. If he orders
the refill, that order is automatically sent to the pharmacist, who then
contacts the patient.
But the biggest benefit, according to James, is the wealth of drug
information he can access prior to entering an order. “I can access
eight or nine different formularies, so I can get the patient on the
right medication right out of the box.” In addition, because the system
reviews therapeutic alternatives for non-preferred drugs, it asks James
if he wants to see an equivalent drug in the formulary.
However, choosing the correct drug is more than just matching a specific
medication with a patient’s illness. One of the system’s major benefits
is its alert system, which red-flags drug-drug or drug-food interactions
and allergies, thus reducing the chances for serious or fatal medication
errors. To ensure that physicians have the latest data on all available
medications, Gold Standard also provides regular updates to PDLs
(Preferred Drug Lists). James began using eMPOWERx about two years ago
and found it simple to use, saying that it takes only one or two days to
get up to speed. Use of the technology also grew among his students.
“I gave the residents the option,” he says. “Only two out of 20 opted
out.”
However, there is no opting out when it comes to patient safety. Whether
it is scanning a bar code on a medication at the bedside, getting the
correct drugs from the pharmacy to the nurse, or checking formularies to
determine the most appropriate drug prior to ordering, the primary goal
is to reduce medication errors and to prevent tragic outcomes that are
still too common in institutions charged with the responsibility of
saving lives.
