Just minutes may be needed now for a process
that even two years ago, before voice transcription technology
had matured, might have taken days.
ASP model for dictation/transcription
Southlake Regional Health Centre has stepped
into the Web world as the first Canadian hospital to use a dictation
transcription service from MedQuist Canada that leverages an
Internet-based application service provider (ASP) model.
Dictation technology produces transcribed reports within
minutes
Physicians can now dictate their notes into
a Palm handheld computer as they see patients, upload the sound
file into their desktop PC and watch as their voice notes are
quickly converted into text reports.

Web site provides forum for Canadian EMR users to share experiences
By Neil Zeidenberg
Where do Canadian physicians go when seeking
information on electronic medical records (EMR)? Where can they
learn what other physicians are saying about specific EMR
products?
Until recently, any such search on the Net
would only lead to American reference sites. However, a Canadian
physician recently launched a new Web site where Canadian users
can visit and learn from each other.
CanadianEMR (http://emruser.typepad.com/canadianemr/)
is an online resource for Canadian physicians and EMR users to
share information and to discuss their experiences.
Its created and moderated by Dr. Alan
Brookstone, a family physician and CEO of Cientis Technologies,
a medical consulting company. He has written numerous articles
on the use of technology in delivering healthcare.
Theres nothing like this on the
Web for Canadian physicians, says Dr. Brookstone. I
hope it encourages them to visit the site on a regular basis
becoming a meeting place for information on EMR.
CanadianEMR is a Web log where users discuss
not only their successful experiences, but also the obstacles
and pitfalls of EMR and its vendors. Moreover, the message board
covers topics like privacy and security issues. By simply clicking
on the comment link, a user can respond to what they see.
Other features of the site include handy
tips for EMR users and useful links.
Dr. Brookstone believes CanadianEMR is a good
resource because its useful to know what others are saying
about EMR in their region. Its a question that comes up
frequently in discussions, but is rarely answered adequately.
The Web site will have guest authors, chosen
by Dr. Brookstone, speaking on a variety of topics. He has already
heard from a number of ex-physicians who are eager to participate.
As Dr. Brookstone explains, the site is user
friendly, with no need to register a user name and password.
Visitors need only to read the postings and then comment
on what they see.
Another feature, Rate Your EMR, is a general
discussion and not specific to good/bad experiences. As part
of the sites code of conduct, its requested that
comments should be constructive. Postings thought to be inappropriate
will be excluded and senders may be blocked from future participation.
Despite its newness, the site is garnering
plenty of interest. Launched January 1st, it attracted over 1,000
hits in the first 10 days.
And the site can be a huge advantage for vendors,
too.
The message board will give the vendor
community an opportunity for the good systems to rise to the
top, says Dr. Brookstone. Each submission is first reviewed
for content and must include the writers contact information
for verification purposes; though not all postings will be of
a positive nature.
To post only the good experiences is
not realistic, says Dr. Brookstone.
The Web site is updated on a daily basis.
Its also easy to manage; taking roughly 15 minutes of Dr.
Brookstones time each day. This means he can manage the
site on his lunch break. Currently, there is nobody assisting
him in maintaining the site, no webmaster. Right now, its
maintenance free.
As far as costs go to maintain the site, its
rather insignificant, about $14 per month on the
high end. Says Dr. Brookstone: The time commitment is minimal
right now, though it will depend on how popular the site becomes.

Leading Canadian surgeon assists U.S. space program
By Patricia Famely
Dr. Mehran Anvari, a surgeon at St. Josephs
Healthcare Hamilton, recently returned from a two-week visit
to the NASA Space Centre in Houston, Tex. The telerobotics pioneer
was exploring ways to extend the frontiers of medicine into space.
Dr. Anvari is also the founding director of
the Centre for Minimal Access Surgery (CMAS), and an expert in
laparoscopic surgery. He pushed those frontiers into new territory
earlier this year when he performed the worlds first hospital
to hospital telerobotics-assisted surgery. Dr. Anvari, assisted
by Dr. Craig McKinley in North Bay, Ont., successfully operated
on a patient across 400 kilometres from his computer console
in the OR department at St. Josephs in Hamilton.
The National Aeronautics and Space Administration
(NASA) is looking for that kind of skill, experience and vision
as they investigate ways to deal with possible health problems
faced by astronauts. NASA hopes to create systems that will enable
an Earth-bound physician to perform surgery on a patient orbiting
on a space station, on the moon, or even another planet.
Dr. Tim Broderick, a surgeon/scientist working
with NASA, invited Dr. Anvari to the Space Centre to take part
in early experiments on surgery in space. Dr. Broderick was on-hand
last year to watch the Hamilton-North Bay procedure that used
fibre optics. Our work has significant implications for
space, and as were the only site in the world doing this
kind of work, hes been keeping a very sharp eye on us,
said Dr. Anvari.
Dr. Anvari headed south with Dr. McKinley,
CSA astronaut Dr. Dave Williams and Bell Canadas Harvey
Stein who designed the network for the telerobotic program.
The primary purpose of the trip was
to be part of a series of experiments to look at the effect of
zero gravity on completion of laparoscopic tasks. We used simulated
environments to test the ability of the surgeon, an astronaut,
and some technical staff whod been trained to perform a
variety of laparoscopic skills under zero gravity conditions,
said Dr. Anvari. We also presented to a multi-lateral medical
operations taskforce made up of the medical directors of various
space agencies on telerobotic surgery and its implications for
space.
Dr. Anvari said that his aim is not just to
develop technology for space. We want to develop technology
that will help Canadians. Satellite technology could open many
remote corners of the country which dont have land-based
facilities, yet need medical services.
There is a Canadian Space Agency (CSA) satellite
outside the Charlton Ave. hospital site of St. Josephs
Healthcare Hamilton with which Dr. Anvari is investigating the
possibility of doing telerobotic surgery using satellite technology,
rather than the current land-based (fibre optics) technology.
The first week in Houston was taken up with
experiments and on-site training. Although Dr. Anvari trained
for six months prior to the visit, he needed further orientation
to face the next challenge. He took off in the so-called Vomit
Comet. The KC-135 plane takes its passengers on a rollercoaster
ride that simulates weightlessness, or microgravity.
I trained physically to make sure that
I was fit. Clearly, with the KC-135 flight, the fitter you are
the more likely you are to be able to complete your task without
being affected by the constant changes in gravity from 2G to
zero G and the impact that has on your body. Fortunately the
people in our group were fine and had no problem, said
Anvari.
It was a fantastic to experience zero
gravity and see how everything feels and floats away in zero
gravity. It was great to be able to get to know some of the astronauts,
to get a chance to get a feel for how NASA works, and to present
at a high level to the heads of the medical directories of the
space agencies.
The results from the experiments are now being
analyzed.

Voice recognition for radiology speeds up transcription turnaround
By Andy Shaw
Its not quite out of Star Trek yet but
its getting close. Bones (Dr. Morris Goldfinger) sits in
his medical command post in the Edward Street Radiology Clinic
in downtown Toronto. Its a clinic that he founded, and
is now the largest single private radiology clinic in the country.
He mouse-clicks his radiological system inbox for the latest
x-ray image sent his way from a satellite office in Montreal.
Up comes a crystal clear, side-view image of a cranium and its
connected neck bones. After a few minutes of careful study and
one more click, theres a sound cue tone for Dr. Goldfinger
to begin dictating his findings.
Mandible x-ray, paragraph. The bony
structures appear normal without evidence of arthritis, period,
says Dr. Goldfinger, in a normal voice and dictating the punctuation
he wants in the text as he goes. Soon hes into the technical
terms of radiology that most people wouldnt know how to
spell without consulting a medical dictionary. Then he concludes:
Normal examination, period.
Another mouse click, and there are the words
hes just dictated. They appear letter perfect even
the arcane radiological terms and are complete with correct
punctuation and paragraph spacing. A quick but careful review
of the text by Dr. Goldfinger follows and he sees the need for
inserting a phrase. One more click at the insertion point in
the text on the screen and he says of the mandible
and instantly the words appear in the text between examination
and the period of the last sentence.
Satisfied, Dr. Goldfinger clicks a blue button
on his Dictaphone PowerScribe handset and turns to speak to an
observer with a satisfied, There, its all done.
What was done in those few minutes represents
a quiet revolution in medical dictation. Not only had Dr. Goldfinger
conducted an evaluation of a remote patient but with the utmost
efficiency, he had also seen, signed, and sent his findings to
the referring physician via his Radiological Information System
and an automated fax machine pre-loaded with physicians
addresses. That one final click also sent the Montreal image
and accompanying report into an Edward Street archive, from where
they can be instantly called up on his screen should the referring
physician wish to talk to Dr. Goldfinger about his interpretation
of the image. The click also triggered the Edward Street clinics
accounting software that then automatically prepared a bill to
Ontarios health insurance plan, OHIP, for Dr. Goldfingers
services.
All that took just minutes for a process that
even two years ago, before voice transcription technology had
matured, might have taken days.
We used to dictate on audio tapes and
send them to our typists, so you wouldnt even see your
report for review, editing, and approval for at least four or
five hours, says Dr. Goldfinger. Then, even what
youd fixed, signed and sent off the report, if the referring
physician called back, youd often end up scrambling to
find it on some clerks desk in a stack waiting to be filed.
With the Dictaphone system running the Edward
Street show for a year now, thats all gone including
all five of the clinics typists and half the clerical staff.
The system gives us a very productive
infrastructure. Overall weve been able to reduce our staff
while carrying out the same amount of work, says Dr. Goldfinger.
And thats a prodigious amount of work. Dr. Goldfinger estimates
he and the other four full-time radiologists and a couple of
part-timers at his clinic (with the help of five servers and
a full-time IT staffer in the back rooms) pump out over 500 interpretations
and reports a day. All handled as neatly and digitally as the
demonstration Dr. Goldfinger gave above. Without the people
we used to need, we have a very economical infrastructure, so
expanding it doesnt cost much. Thats why last year
we were able to open another Toronto clinic, he says.
Getting up to speed on the new system for
newcomers is not difficult, either. It took about two hours for
each radiologist to train PowerScribe to recognize
the quirks of their individual voices. Then over the course of
another month, the system learns on its own to better understand
what the dictating rad is saying.
After the first two hours of training,
the system was remarkably accurate, says Dr. Goldfinger.
After we hit that first month threshold, it became incredibly
accurate.
The dramatic rise in computer processing power
has helped improve the quality of voice transcription, says Don
Fallati, Dictaphones U.S.-based vice president. But
more than anything else it is the language modelling
we do at Dictaphone and work so hard at. And in this case we
applied that modelling specifically to radiology so that the
system would recognize or quickly learn to recognize all its
specialist terms.
As good as it is, theres at least an
awareness challenge that goes with greater adoption of voice
transcription by the healthcare community.
I think a lot of physicians in the past
may have experimented with dictation and transcription using
off the shelf software that wasnt adapted to their profession,
and they consequently found it wanting. But many doctors arent
aware of the dramatic improvements there have been in the technology
over the last 18-24 months, says Duncan Salt, General Manager
of Dictaphone Canada in Mississauga, Ont. Considering the
millions of dollars that healthcare is spending each year on
manual transcription, its time for doctors to re-visit
their computer, I think, to see how things could be improved.
Judging by Dictaphone sales of PowerScribe,
especially in Ontario, some radiologists have indeed been heeding
the advice and re-visiting their keyboards and microphones.
There are some areas in the Maritimes
and out in BC that have shown strong interest in our systems,
but Ontario is clearly the leader in adoption, says Ben
Hebb, Dictaphone Canadas head of sales for Ontario, (and
the person who gave the demonstration of PowerScribe that Dr.
Goldfinger admits bowled him over).
We could soon have upwards of 15 installations
in Ontario, and they range in size from the smallest clinics
to the largest hospitals.

ASP model for dictation/transcription means faster service
at Southlake
By Dianne Daniel
Southlake Regional Health Centre has stepped
into the Web world as the first Canadian hospital to use a dictation
transcription service from MedQuist Canada that leverages an
Internet-based application service provider (ASP) model.
The Newmarket, Ont.-based facility signed-on
to MedQuists DocQment Enterprise Platform (DEP) in September
2003, and according to Anthony Reddick, Southlake manager of
health information and decision support, the most noticeable
change since then has been the speed of service.
The glory is that turnaround time has
improved with this system, says Reddick. He notes that
the goal of the new system was a turnaround time of 24 hours.
Theyre beating those time lines, based on what Ive
been hearing back from the physicians.
Prior to choosing the MedQuist DEP service,
Southlake was managing its own in-house transcription system,
which Reddick refers to as antiquated. Transcriptionists were
supplied by MedQuist and worked from home, but the hospital had
reached a point where it was necessary to upgrade its equipment
in order to support ongoing dictation.
Rather than investing in another hardware
solution, Southlake decided to look at outsourcing as an option.
Like most hospitals, were tight for IT capital,
says Reddick. So to have an approach that would allow us
to convert dictation to an operational cost has its benefits.
With MedQuists DEP, everything required
to handle medical dictation is supplied to Southlake, including
a gateway PC and server. Physicians create voice files, which
are sent on to MedQuists regional data centre in Alpharetta,
Ga., over a toll-free line.
Files are then captured in the centres
Oracle database, where theyre matched to Southlakes
Admission/Discharge/Transfer (ADT) system through a real-time,
HL7 interface, so that patient demographics can automatically
be inserted. From there, files are available over a secure Internet
connection to trained medical transcriptionists, who use PCs
to access and transcribe the notes.
Now that theyre dictating into
our data centre, with just a click of a few buttons we can have
a thousand transcriptionists able to access their voices,
comments MedQuist national project manager Jim Wheeler, who led
the implementation. One of the biggest changes, he adds, is that
the number of available transcriptionists is no longer tied to
the number of available ports on the in-house dictation system.
Another significant change is in how the notes
are returned to Southlake. With the old system, medical staff
didnt have on-line access to dictated notes. With DEP,
using proprietary technology for printing and viewing of documents,
returned notes can be printed or viewed on any floor, station
or printer in the hospital, or viewed remotely as long as a physician
already has secure outside access to the hospital.
According to Reddick, the ability to print
from more than one location was a key factor for Southlake. Before
deciding to outsource its medical dictation, the hospital surveyed
other sites to determine any shortcomings and found that the
need for distributed printing was mentioned repeatedly. I
spoke to a number of hospitals and looked where they fell down,
say Reddick. And one of the things was they couldnt
get documents to print where they needed them to print.
Reddick encourages any facility considering
an ASP model to do its homework and look at what has gone wrong
at other outsourced sites. For example, Southlake also ensured
a high level of detail in its contract with MedQuist, because
it could see where other hospitals got burned because they
didnt investigate that thoroughly.
As MedQuist Canada director of operations
Carey Silverstein explains, the first step in providing the ASP
platform is a discovery process, during which MedQuist determines
the needs and wants of a hospital, such as expectations, requirements
and timelines. From there, the company produces a detailed project
plan, so that a client hospital knows exactly whats going
to happen every week until the go-live date. Part of that plan
involves customizing the solution so that it interfaces to existing
hospital information systems.
With this system we were able to give
Southlake exactly what they wanted, says Silverstein. In
the past, the dictation and transcription industry has consisted
of a lot of canned applications, but here, we have a lot of flexibility
with what were offering.
For Silverstein, the transition to an ASP
model for transcription is as big a leap as the move from cassette-based
to digital dictation. The community is very cognizant of
whats happening, and the feedback were hearing from
the majority of our clients is that they no longer want to purchase
hardware anymore, he says.
MedQuist Canada, based in Concord, Ont., is
currently transcribing 30 million lines of dictation annually.
The intention is to migrate all of its current customer hospitals
onto the ASP model in 2004 and then branch out to new clients
next year. As soon as a critical mass is reached, the company
plans to launch a Canadian-based data centre in the Toronto region,
so that voice files no longer have to cross the border.
At Southlake, future plans include the addition
of speech recognition capabilities, as well as autofaxing support
for dictated documents, all of which are currently offered by
MedQuist. Meanwhile, all dictation for health records, excluding
diagnostic imaging, lab and pathology, which are handled in-house
using the MedQuist platform, will continue to be outsourced.
Im kind of embarrassed when I
talk to peer hospitals that are having so much grief, and theyre
weeks and months behind with their on-site transcription,
says Reddick. Right now, its just something that
functions so effortlessly here.

Dictation technology produces transcribed reports within
minutes
By Neil Zeidenberg
TORONTO Physicians can now dictate
their notes into a Palm handheld computer as they see patients,
upload the sound file into their desktop PC and watch as their
voice notes are quickly converted into text reports.
The new dictation/transcription application, called VoiceMD,
is available through Toronto-based VoicePC Inc. (www.voicePC.ca)
It includes special software that dramatically improves the sound-recording
quality on a Palm handheld computer.
And using voice-to-text conversion, it also enables doctors to
produce medical reports in minutes, instead of hours or days
when using a dictation service.
Doctors dont need to wait 24 to 48 hours to have
the transcription sent back to them, says Waleed Qirbi,
president of VoicePC. Instead it takes 24 to 48 seconds
to have their five-minute dictation transcribed from the Palm
in front of them. This means the file can be completed, signed,
and printed the same day. It gives instant results.
Physicians can beam their files wirelessly to a desktop PC by
using the new Palm Tungsten computers, or they can upload files
in the traditional manner by simply placing their handheld into
a cradle and transferring the report.
A secretary or assistant can then scroll through the file, correcting
any obvious errors. Making the review process easier is that
the physicians voice overlay remains embedded over the
text, providing audio confirmation for the secretary during her
review. The physician can then quickly scan the report and sign-off.
VoicePC offers hardware and software bundles that include licensed
voice software from ScanSoft. Also available are over 30 templates
providing speech vocabularies for a wide-range of medical specialties,
such as neurology, endocrinology, oncology, and urology.
The Palm computer enables physicians to carry patient records,
decision support tools and a dictation machine all in one lightweight
device.
Unlike heavier notebook computers, which can drain their batteries
in two hours, a Palm can last significantly longer on a single
charge. What is more is that users are even able to recharge
at a much faster rate than a standard laptop. This translates
into less downtime for a Palm handheld in comparison to a notebook
computer.
Weve moved into the Palm and Tablet PC market,
says Qirbi. But the Tablet has been more cumbersome and
expensive, making it the second or third choice for doctors.
Price-wise, a Tablet PC with headset, 1GB of RAM, Dragon NaturallySpeaking
Medical software, and enhanced recording software has a purchase
price of approximately $5,000. However, a Palm with the same
bundle is closer to $1,500.
All voice-recognition software will make mistakes users
can expect an error rate of about 5 percent.
But VoicePC makes errors fairly easy to correct. While on the
desktop and using a headset, the user identifies misspelled words
and, via voice commands, asks the system to either delete or
fix the word.
The system does have the ability to adapt to the intonation and
inflections of the user.
The more its used, the more accurate it becomes,
explains Nicholette Williams, an account manager for VoicePC.
And with fewer errors to fix, and record turnaround time,
the need for transcriptionists can be eliminated.
For many doctors, clinics and hospitals that outsource their
transcription services, that could translate into substantial
financial savings. It also gives users more control over when
their patient files are completed.
The first time the software is used, the user simply reads along
with a dialogue box which highlights as words are recognized.
For most VoicePC users, this means simply having the computer
highlight each word as it is spoken. This creates an initial
user vocabulary, which eventually results in the user being able
to convert voice to text on-screen in real time. With language
models now available in multiple languages, VoicePC Computers
are available in both English and French.
VoicePC also provides training with the delivery of every system.
This ensures the client is comfortable using it from the start.
Qirbi notes that without basic training, most people become frustrated
and quit because they dont know how to use voice-recognition
software properly. Even worse, out of the box, most voice recognition
systems dont work well because the PCs on which they run
have not been optimized for the application.
Our systems are customized specifically for use with voice
recognition software, said Qirbi. We know the product
works because we build the product and test the product to ensure
that every system is ready for use upon delivery.
Waleed Qirbi was born in Ottawa, and is an MBA graduate of the
Joseph L. Rotman School of Management in Toronto. He also has
a BA in political science from the University of Western Ontario.
While studying for his MBA, the discovery of a brain tumour affected
all but 15 percent of his vision. It was in his return to complete
his MBA that he was exposed to voice-recognition technology.
After gaining experience with the systems, Qirbi decided to create
new applications for others such as physicians. He believes
the timing is right for the VoiceMD line of products, as Palm
computers are popular among physicians and the voice dictation
system provides a low-cost solution that dramatically reduces
waiting times for reports and increases a doctors effectiveness.
