Feature Report: Pharmaceutical systems
We dont have a body count for Canada yet, but in the United
States adverse drug events or medication errors are related to at least 48,000 deaths
annually. Some estimates run as high as 180,000. Given the 10-to-1 population ratio
usually used to equate statistics between our two countries, a reasonable guesstimate
would still leave Canadians dying unnecessarily in the thousands each year from the wrong
drug, or the wrong amount, administered at the wrong time, or to the wrong patient.
Radiologists say $1 billion investment needed for imaging
To avert a looming crisis in diagnostic imaging, the Canadian
Association of Radiologists has urged Ottawa to create a $1 billion investment fund to
bring Canadas relatively feeble stock of medical imaging equipment up to world
standards of quality and quantity.
Canadas first telehospice
Prince Edward Island has launched the countrys first telehealth
trial for palliative home care. The videoconferencing system makes use of medical

Welland hospital begins best practice breast cancer surgical treatment
By Patty Welychka
There are four words that strike terror in every womans heart.
They occur when a doctor tells you, you have breast cancer.
What the physician can now also tell patients in Welland, Ont., is that
there is a new, innovative method being used in a pilot program at the Welland County
General Hospital that may be the best way of treating breast cancer the world has seen
thus far.
Stereotactic biopsy and lymphatic mapping are on the cutting edge of
breast cancer treatment and happening locally, thanks to the initiatives of many staff
members at the Welland Hospital.
If a woman detects a suspicious lump in her breast, her family
physician will most likely send her for a mammogram. If something shows up on the x-ray, a
stereotactic biopsy can be taken right away.
The stereotactic instrument, new at the hospital here, attaches right
to the mammography unit. In a very quick movement, five small needles take samples from
the lump - one from the centre and four from around the perimeter. Samples are then
analyzed in the lab to ascertain whether or not a malignancy is present.
Dr. Peter Willard is spearheading lymphatic mapping in Welland. To say
hes excited would be an understatement.
Its like this, really: lymph nodes drain the breast. When cancer
cells are detected in the lymph nodes, a patients survival rate drops dramatically.
The standard procedure has been to remove the majority of axillary
nodes. With lymphatic mapping, only the lymph nodes draining the site are sampled.
The use of radioactive material (a minute amount, Dr. Willard says) and
a special blue dye can help surgeons locate these lymph nodes. By looking more closely at
them, doctors can see subtle signs of cancer spread, which might otherwise go undetected.
With the use of new technology, a navigator probe is used to identify which
areas of tissue need to be further examined. This probe is used in the operating room as
the surgeon carries out the procedure.
Dr. Willard says he became enthusiastic about the procedure
approximately two years ago while taking courses in San Diego.
We want to minimize the amount of pain people have. Our goal is
not to cause pain, but to relieve disease, Dr. Willard says. With Sentinel
lymph node biopsy, we remove the node that is draining the tumour and see if the disease
is spreading. It is extremely exciting.
The procedure has been performed on 17 patients in Welland over the
last few months, the first in June of 1999. The trial entails 20 people. Dr. Willard has
hopes the procedure will become a day surgery.
With complete axillary node dissection (removal of all the lymph nodes
around the breast tissue) women can suffer nerve damage or lymphedema (the swelling of the
arm). With lymphatic mapping, major motor nerves are not cut critical for a
positive healing. In fact, the ideal procedure only involves an incision thats about
an inch long.
When you know exactly what youre aiming for, theres
no tissue disturbance or major nerve cutting. The patient wont need a drain and
there will no longer be a need for home care services afterwards, Dr. Willard adds.
The pre-op clinic consists of blood work, a chest x-ray and an
electrocardiogram. Next comes the visit to the diagnostic imaging department, where the
patient will receive an injection of a weak radioactive dye in about six areas
around the breast.
A Gamma camera (also new at the hospital) will take pictures of the
area and the radiologist will mark the sites on the womans skin. Its crucial
that the site of the injection be massaged vigorously for about 10-15 minutes.
Next day, in the operating room, the surgeon will inject a blue dye
around the tumour site. The sentinel node will be removed, and then a radioactive detector
probe will help find other lymph nodes that also need to be excised. The entire procedure
takes about 45 minutes to an hour. Dr. Willard hopes to have that whittled down to about a
half-hour.
Women should not be alarmed if they notice a blue-green colour in their
urine afterwards (from the dye). This is normal and will not last long.
If women and their significant others tap into the Internet to try to
find out more about lymphatic mapping, Dr. Willard suggests they discuss their findings
with their physician. No one polices the information on the Internet and much
of the information found there can be misinterpreted, if not discussed with an appropriate
medical professional.
As a young physician and being computer literate, I can
appreciate the Internet. But many people talk as if what they find there is the
gospel, Dr. Willard says. It allows people to see and read about different
treatment options, but often people will believe their talk show host over their doctor.
People shouldnt take much of what they find on the Internet as sound medical
advice.
Dr. Willard is proud that lymphatic mapping is well on its way in
Welland. In some ways, we were able to start our program faster because there are
fewer layers of bureaucracy, he says.
One key to the successful implementation of the program was the use of
clinical and patient pathways. Clinical Pathways were used to streamline communication
between departments, provide consistency of information between care providers and used as
an educational tool for staff in understanding a new surgical treatment.
The patient pathways were given to patients in the pre-surgical clinic.
These pathways were expressed in laymens terms and explained the new procedure and
what to expect as far as the new procedure itself, hospital stay, information about the
Internet, home care visits and follow up protocols.
The Clinical Resource Management Program has undertaken the
responsibility of keeping a formalized database for all patients having the procedure.
Patient outcomes will be followed and monitored at certain intervals over a five-year
period. This initiative will enable surgeons in our area to identify short and long-term
outcomes for this particular patient procedure.
The Welland County General Hospital continually identifies
opportunities for improvement. Lymphatic Mapping definitely has Welland on the leading
edge of best practice treatments and protocols for patients in the community that we
serve.

Program at the Welland County General Hospital. This story was written with files from

Communication is the key to success in a high-quality, drug-checking system
By Andy Shaw
We dont have a body count for Canada yet, but in the United
States adverse drug events or medication errors are related to at least 48,000 deaths
annually. Some estimates run as high as 180,000. Given the 10-to-1 population ratio
usually used to equate statistics between our two countries, a reasonable guesstimate
would still leave Canadians dying unnecessarily in the thousands each year from the wrong
drug, or the wrong amount, administered at the wrong time, or to the wrong patient.
The latest technology and pharmaceutical dispensing systems are not by
themselves a fail-safe against these sad numbers. Even in hospitals following sound
unit-dose practices where nurses can only administer one pill at a time to a patient
because automated dispensing machines meticulously label and package individual doses for
individual patients, human eyes and hands must still keep careful watch. Every now and
then, an individuals package turns up with two different pills in it, with no pills
in it, or with two different labels on it and must be plucked manually from distribution.
Still, theres some impressive equipment out there already cutting
down on those potentially fatal margins of error. At the Sunnybrook and Womens
College Hospital in north-end Toronto, a robotic arm in the pharmacy department has been
selecting drugs from bar-coded bins more than a million times over without error. At the
West Park Hospital in Toronto, Autros Hospital Systems Inc. of Toronto, is casting the
last link in the countrys first end-to-end automated medication management system.
For more than a year now, West Park, a long-term care facility, has had a wireless point
of care system from Autros at work which links the nursing teams and hospital pharmacists
at the patients bedside.
A pass by the nurse of a hand-held infra-red scanner over a
patients wrist band, the bar-coded medication and the nurses own ID card just
before the pill is popped, confirms that the right medication is being administered to the
right patient at the right time and, just in case something does go wrong, by whom. Now,
Autros has completed the chain by enabling physicians to make the order entry of the
prescribed drug electronically.
We know that 55 percent of medication errors come at the
order-entry point. But doctors dont have much patience when it comes to
technology, says Eric Paul, a former pharmacist and president of Autros. So it
took us a long time to design a piece of (order-entry) equipment that involved minimal key
strokes and was very user friendly.
Within six months, Paul says, Autros will have made its first foray
into markets south of the border and installed similar doctor-friendly systems at five
sites in the United States.
Michael Cohen will be very glad to see them.
Cohen is president of the Institute for Safe Medical Practices (ISMP),
a nonprofit organization headquartered in Huntingdon Valley, Pennsylvania. At the annual
Canadian Society of Hospital Pharmacists (CSHP) forum in Toronto in February, Cohen told a
packed session how the misinterpretation of a physicians hand-written drug order
resulted in a 10-fold overdose and consequent death of a Denver infant.
We made a study of that incident and found, as we so often do,
that it really wasnt the physicians nor the administering nurses
fault, said Cohen. We identified 54 separate events that if any one of them
had occurred differently, the process would have been diverted and the child would not
have died. But tragically not one did. And thats the point. So often the media
single out the doctor or the nurse but, in most cases, they are not to blame. It is the
whole system from the drug manufacturers to the bedside thats at fault.
One missing piece in the Canadian system is the absence of any
organization like the ISMP. In co-operation with the United States Pharmacopeia, ISMP
collects medication error statistics and cases voluntarily submitted by American
hospitals.
We go to great lengths to guarantee our contributors anonymity,
and thats what makes a voluntary system work, explains Cohen.
Armed with the data, Cohen and his group can make presentations to
regulators, hospital administrators and drug companies in the hopes of preventing future
tragedies and reducing the huge costs associated with less serious adverse drug events.
The incident in Denver involved confusing two very similarly named drugs. Cohen says the
ISMP has been beseeching the American governments Food and Drug Administration for
some time now to ensure that pharmaceutical manufacturers call their products distinctly
different names.
Cohen is currently helping CSHP officials to design a Canadian-style
safe medical practices watchdog. Meanwhile, the CSHP has launched a Medication Error Task
Force under Dr. David Rosenbloom at McMaster University Medical Centre in Hamilton, Ont.,
to identify how medication error information might be gathered countrywide.
Most hospitals have appropriate pharmacy software modules and a
very good reporting system within the institution, says Bill Leslie, the CSHPs
executive director in Ottawa. But for a number of reasons, liability not being the
least of them, that information is not being shared. So we are not learning from the
mistakes of others. We need to be able to collect information about incidents that does
not identify the patient nor the caregivers but simply the situation. We hope our task
force will come up with a framework for doing that by the end of the year.
Leslie says most pharmacy software, however, is still not fully up to
scratch. Geared to catching allergic reactions or drug interactions, the software does a
faithful job of comparing the scheduled medication against the patients computerized
profile.
The catch-22 is that such programs will often flag a great number
of potential interactions for a given drug, most of which are of no great significance
under normal circumstances, says Leslie. What we need, and there have been
attempts at it, is smarter technology that will do a degree of sorting and point out the
more critical adverse events that are likely.
One of those attempts, the first of its kind to be patented, was
developed by Dr. Timothy McNamara, MD, and registered last year in the United States by
Multum Information Services Inc., where Dr. McNamara serves as a vice president of
research and development. As reported in the April 1999 issue of Health Management
Technology, the patent, identifies systems, methods, apparatuses, and computer
program products that Multum has developed to generate: dosage recommendations, side
effect information, allergies, drug interactions, reproductive information,
pharmacological data and cost information.
The company says its system will actively take into account patient
characteristics such as age, kidney and liver functions, and the disease being treated.
But mention Multum even at a pharmacists convention and few have
heard of it.
Nonetheless, it is the kind of push technology Eric Paul at
Autros believes will become the decision support standard for hospitals, one hopes, in the
not too distant future.
The problem in the past is that the physician, the pharmacist,
the lab, and the nurse are not communicating in real time, explains Paul.
Lets take the example of a nurse at the bedside, where about 35 percent of
medication errors occur. A doctor has ordered the medication, but in the meantime, a lab
test has come back. So, unless the nurse goes to wherever the lab result is stored and
checks it, he or she might end up administering a medication which is inappropriate.
In a real-time electronic system, the lab result is automatically
pushed at the nurse on a communication device, such as the Palm Pilot that our system
uses, whenever the lab values are out of range. When the nurse scans the patient, a
warning will come up not to administer the drug or recommend certain checks be made first.
So you get a much higher degree of decision support for caregivers.
Such a system also makes sure the pharmacist is in the decision-making
loop. Paul says 40 percent of orders submitted by doctors need re-work in paper-based
ordering usually after the prescribing doctor is long gone. (Cohen tells the story
from one ISMP incident of how a paper-ordered drug that the doctor prescribed rather
unclearly was to be administered on the first and the eighth day of a patients stay.
Instead it was administered, nearly fatally, on all eight days.) But if the pharmacist
receives the order electronically, and if there are any issues in it, the pharmacist can
communicate with the doctor immediately or soon after via email. Such interventions can
also be tracked by the system and pushed back to the physician suggesting how to medicate
in a better way.
Cohen reports that adverse drug events are reduced by 66 percent when
the pharmacist is actively involved this way in the medication decision process.
Its a better way to make use of a pharmacists six
years of brilliant education other than counting and packaging pills, comments Paul.
They are capable of being more than just lickers and stickers.
Concludes Michael Cohen: When youve got a closed-loop
pharmaceutical system, such as computers enable, you not only reduce medication errors,
you go from: Who did it?, to the much more important, What allowed it to happen?

Radiologists say $1 billion investment needed for imaging
By Jerry Zeidenberg
MONTREAL To avert a looming crisis in diagnostic imaging, the Canadian Association
of Radiologists has urged Ottawa to create a $1 billion investment fund to bring
Canadas relatively feeble stock of medical imaging equipment up to world standards
of quality and quantity.
Recent studies by the CAR and the Vancouver-based Fraser Institute
found that Canada is lagging most of the industrialized world in the availability of
high-tech imaging equipment such as CT scanners, MRI machines and nuclear medicine
devices. The growing waiting lists for diagnostic tests result from this shortage, the
studies asserted.
According to the CAR, There are widespread reports of patients
being sent to the United States for treatment, and Canadians who can afford it, seeking
access in the U.S. to advanced diagnosis. Also, well-connected individuals who know people
often jump the lines while everyone else waits and ultimately pays the consequences.
The CAR report noted that, High-tech equipment can diagnose
medical problems at their earliest stages, when they can be most effectively treated. Long
waiting periods often lead to a diminished quality of life and ultimately, to the loss of
lives.
Indeed, in terms of MR machines per capita, Canada ranked 19th out of
28 industrialized nations. When it came to CT scanners, Canada finished 21st on the list
and was dead last for bone mineral density (BMD) machines and positron emission tomography
(PET) scanners.
Whats more, it was discovered that a good deal of existing
equipment is out of date, slow and unreliable.
The results of objective studies in Canada show a shocking
deficiency in high-tech diagnosis equipment and some dangerously aging X-ray
equipment, said the CARs recent white paper, titled Vision 2000: Radiology
Services in Canada.
The number of critical diagnostic tools such as MRI units, CT
units, BMD machines and PET scanners per capita are among the lowest in the western world
and compares with supplies in underdeveloped countries.
For example, X-ray systems in certain parts of the country are up to 37
years old, when most medical imaging equipment is considered obsolete after 12 years.
The generally poor levels of diagnostic technology currently available
to the public could lead to a relative decline in the quality of medical care, industry
leaders say. If the diagnosis is inefficient, the treatment is going to be
inefficient, commented Normand Laberge, CEO of the Canadian Association of
Radiologists. Unless adequate supplies of modern equipment are available to hospitals and
the public, Laberge said Canadians face the problem of delayed and possibly inaccurate
diagnoses.
The current state of affairs is dangerous to the public,
said Laberge.
In addition to an immediate $1 billion investment in new technology,
the CAR estimates that an additional $730 million in operating costs will be required in
the first three years.
Just as serious as the technology dilemma is the shortage of
radiologists to provide readings of exams. The CAR says there are currently 150 vacancies
for radiologists across the country, and the association forecasts a shortage of 500
radiologists by 2004.
At the present time, there is one radiologist in Canada per 18,000
population, when the federal government itself has recommended a ratio of one radiologist
per 13,000 population.
According to the CAR, between 30 and 40 radiologists per year intend to
retire in each of the next few years, and close to 10 percent of the workforce is already
more than 65 years of age.
At the same time, the Canadian population is expected to increase by 18 percent over the
next 20 years.
To combat the increasing shortage of radiologists, the CAR says we
must:
Increase immediately the number of residency positions in Canada
by at least 25 percent.
Offer more flexibility in career choices for medical students
across Canada by allowing changes in training programs during residency.
Increase re-entry positions in radiology, allowing and
facilitating practising physicians the opportunity to enter a residency program.
Provide temporary accommodation and facilitation for more
International Medical Graduates in residency programs.
Create a retention and repatriation program for Canadian
radiologists.
The Canadian Association of Radiologists also urged federal Health
Minister Allan Rock to create a national diagnostic imaging advisory committee, consisting
of representatives from: the CAR, organized radiology, heads of academic radiology
departments, Health Canada and provincial ministries of health, and the medical imaging
industry.
Laberge contrasted the poor levels of technology in the Canadian
healthcare system with the state-of-the-art computer technology found in the banking
sector technology that has helped the financial sector become extremely efficient.
Healthcare did the opposite, we didnt invest, and the
result is the waiting periods that are common today, observed Laberge.
Healthcare in Canada is like an automobile thats gone off
the road, he said. It needs a towing to get back on the highway. Thats
what the $1 billion investment in diagnostic imaging would do.

West Island Telehospice: PEI launches Canadas first telehospice project
By Andy Shaw
Prince Edward Islands groundbreaking telehospice project owes at
least a small debt to Frances space program. In December, Digital Telehealth Inc.
based in Dartmouth, N.S., announced it had been named the project leader of an 18-month
start-up of Canadas first network dedicated to palliative home care.
Contracted by the West Prince Health Authority, Digital has worked with
the Canadian Palliative Care Association, Island Tel, Island Hospice, and West Prince
Hospice in a joint effort to bring both cost-savings and improved care to terminally ill
patients. Co-funded by Health Canada, the $126,000 project operates on what Digital CEO
Wayne Bell terms low-bandwidth POTS (plain old telephone service) lines.
A U.S. Food and Drug Administration-approved Aviva System bedside
patient unit from American Telecare enables 15-frame-a-second video transmission (compared
to 30-frames for full-motion video) over those POTS lines.
This allows caregivers working from the systems central unit,
back at the healthcare facility, to see the patient and vice versa. The interactive
peripherals of the system can also keep round-the-clock watch on the
patients temperature, blood pressure, pulse, heart and lung sounds, as well as do
glucose, blood oxygen, and electrocardiogram testing.
The nice thing about these units is that all their data are
automatically uploaded to the patients chart at the central station, says West
Islands telehospice co-ordinator, Myra Ramsey. So there is no room left for
error either on the healthcare professionals or the patients side. Nothing has
to be copied down or read back. So it is 100 percent accurate.
Its also accurate to say that the project is a reflection of the
experience, dedication, and training of the various project partners. Ramsey has been
interested in palliative care since the beginning of her nursing career and did exhaustive
research on suitable systems for the project.
Dr. Rod Elford of Calgary, a principal business partner of Bells at Digital, brought
a unique combination of medical and technical expertise to the work.
When he graduated from medical school in Alberta he went on to
study space medicine in France and that got him involved in telemedicine, explains
Bell. When he came back home he wanted more training, the university put together a
unique two-year graduate program that saw him study telehealth in the United States,
Norway, and under Max House in Newfoundland. So he became the first in the world, so far
as we know, to hold a masters degree in telehealth.
Under Bells direction Digital will also provide the training needed by the
home-based caregivers to run their end of the network.
Were independently developing educational programs for the
caregivers in the home, says Bell. Were looking at the best way to do
that but initially were thinking it will be Internet based because of its
convenience for people.
Patients referred by West Prince physicians for palliative care
services are eligible for telehospice hook up. Initially the system will handle just 12
remote patients. But even at that size, the world is going to know about it. Digital will
be exhibiting its telehealth developments in the Canada Pavilion at the new
millenniums first Worlds Fair in Hannover, Germany beginning in June. Some 200
countries are participating and over 50 million visitors are expected at the five-month
long event.
But its not the big show that motivates most, says Bell.
Its the little 15-frame-a-second bedside images that will appear somewhat
intermittently, but clearly, to PEIs telehospice nurses on their central station
screen. (Privacy is assured. At the patient end, a button must be pushed before any
bedside images are transmitted.)
It seems that home care has been down the list of telehealth
projects in Canada, yet the greatest volume of patients are actually in the home,
says Bell. So home care is where youre going to get the greatest bang for the
healthcare technology buck. This has to be more than just about major hospitals connecting
with each other.
Bell adds that when you put the microscope on such major,
high-cost IT projects, its difficult to identify what savings or other tangible
benefits are being achieved. But when a dying patient, for example, can be cared for
professionally via an inexpensive telehospice network at home rather than at the hospital,
the benefits to the patient, to his or her family, and to provincial health care costs are
obvious.
Ive had the daughter of one patient already tell me how
grateful the family is that weve been able to leave her mother at home and yet still
know and see what her condition is, says Ramsay.
Ramsay describes the breadbox-sized Aviva unit as having a camera eye
on its upper edge, a speaker-phone, a small computer-like screen for video and a read-out
interface so that the patient or home caregiver can also see the readings being
transmitted back to the central unit. Two simple buttons operate the device.
Both Bell and Ramsay fully expect the telehospice network and its
simple, low-cost technology to carry on long after its initial 18-month pilot stage. It
can be readily extended, they say, to other types of patients at further cost savings to
the healthcare system.
