In the course of sketching a plan to acquire and deploy PACS,
hospitals sometimes make the mistake of assuming that the
introduction of this technology will automatically eliminate all
workflow problems associated with film use. At The Toledo Hospital
in Toledo, Ohio, such assumptions were not permitted. The 717-bed
tertiary care facility, which acquired PACS in 2002, wisely girded
itself for PACS installation by first taking pains to resolve the
productivity, efficiency, and quality-control issues inherent to
its analog-based operations, says Dan Singer, MD, FACR, medical
director of radiology and diagnostic imaging. "Anything less would
have been counterproductive," he says.
Gary Gordon, RN, senior vice president and chief operating
officer, agrees. "We took the position that, if processes we had in
place were not optimized in a manual environment, they certainly
wouldn't be any more optimized by switching over to an electronic
environment," he says.
Roberta (Bobbi) J. Miller, RTR, CRA, radiology administrative
director, was hired 2 years ago to improve processes and prepare
for PACS. She says, "I'm a firm believer that you shouldn't start
implementing any kind of computerization unless and until you have
an efficiently functioning film fileroom. Otherwise, you end up
with a garbage in, garbage out scenario."
Miller knows what she is talking about: "Our film fileroom was
the area where we had the greatest need for more pre-PACS
efficiency. We felt that, once the fileroom was put in optimal
condition, our conversion to PACS would go smoother, faster, and
generally be more successful."
That prediction was proven right.
ROOM FOR IMPROVEMENT
The Toledo Hospital is one of the city's oldest such facilities,
having opened in the late 1870s (although not until 1931 did it
move to its current location). Within the past decade, Toledo
Hospital joined 11 other hospitals in the region to form the
ProMedica Health System, for which Toledo Hospital serves as the
adult and pediatric tertiary referral center, thus attaining for
itself a market reach extending into 23 Ohio counties plus several
more in southeastern Michigan.
Thanks to the hard work of its 800-member medical staff and
4,500 employees, Toledo Hospital today claims a reputation for
top-notch neurosurgery, vascular, cardiology, and cardiac surgery
services. An on-campus children's hospital (featuring a 60-bed
neonatal ICU) means Toledo Hospital also is well known for its
pediatrics, obstetrics, and fetal medicine.

Some 25,000 inpatient admissions are handled at the hospital in
a typical year's span. For the radiology department in 2002, that
translated to orders for 240,000 imaging procedures. This year, the
department projects it will perform about 1,000 more such studies,
a sign that business in general for both the hospital and the
department is up slightly.
Much of this diagnostic work is conducted in a quartet of x-ray
rooms, a trio of fluoroscopy berths, a pair of emergency department
(ED) direct radiography (DR) rooms, three CT scanner areas, six
ultrasound closets, seven nuclear medicine rooms, and two MRI
suites. Additional work takes place in imaging sections at 11
outpatient centers, most of which are equipped with plain-film
radiography and mammography machines (except for one that also has
CT, fluoroscopy, ultrasound, and, soon, MRI).
Given the volume and variety of imaging studies generated at
Toledo Hospital and the on- and off-campus distances film files
must travel, it perhaps was inevitable that the enterprise would
find PACS of great interest. When Miller arrived at Toledo Hospital
in March 2001 to lay a proper foundation for the PACS that was soon
coming, the first thing she did was assess the strengths of the
manual film production, collection, reading, reporting,
distribution, and archiving practices then in place.
"Much of what I found was good," she recalls. "The technical
staff, in particularthey were talented, dedicated people."
There was, of course, room for improvement. And it was in the
film fileroom that Miller would uncover the greatest opportunities
to render improvements.
"Mainly, I discovered that workflow was not as efficient as it
could have been," she says. "Too many steps required to accomplish
tasks, for example."
Among Miller's goals was to increase the speed at which records
could be retrieved in the fileroom so they would more expeditiously
reach physicians requesting them. An envisioned benefit of this
would be shortened length of stay, since having records available
faster meant that physicians could intervene with patients
earlierand earlier intervention might well result in patients
getting well enough for discharge sooner, she says.
One minor sticking point in mapping out what to do about
fileroom efficiency was the matter of how many months of film
archive capacity should be maintained on campus at all times.
Senior decision-makers projected a financial benefit by moving to
off-site storage all films older than 2 months. This, they thought,
would free up space on campus for income-producing uses. However,
Singer disagreed, saying that off-site storage of all images older
than 2 months would generate significant expense.
"It would require us to make extensive use of couriers," he
remembers cautioning. Singer's idea was to maintain an on-campus
archive of films up to 12 months old. "Far fewer courier trips per
day would be needed," he says. "That would mean a very substantial
cost savings right there alone."
Singer also said that retaining on-site films up to 12 months
old would result in faster turnaround of requests from referring
physicians and radiologists seeking prior images. Eventually, top
administrators and Singer agreed to preserve the space in question
for fileroom purposes.
CHARTING THE FLOW
One of Miller's first moves in attempting to boost fileroom
efficiency entailed a customer service survey of referring
physician satisfaction. In so doing, she hoped to gain a better
understanding of the strengths and shortcomings of the fileroom as
perceived by those outside the department.
Miller based those reorganization plans to a significant degree
on established workflow patterns. "I made an analysis of the steps
each staffer took in order to create a file jacket, load the jacket
with content, put it away, label the content, field requests for
retrieval, pull requested files, deliver them, bring them back to
the fileroom, and return them to their proper resting place," she
says.
Her analysis included making flowcharts of those steps. From
those charts, she was able to clearly see which steps could be
eliminated, which could be pared, and which needed no modification.
She also could identify places where entirely new steps could be
inserted either to form shortcuts or to accommodate the performance
of new or revamped tasks.
To support the new workflow she developed, Miller specified that
extra shelving be installed to help maximize the amount of fileroom
space available for storing jackets and other records.
"We revamped the physical positioning of furniture and fixtures
so we would have more wall space for more shelving," Miller
explains.
A number of small desks scattered alongside the walls and in
corners were removed. In their place, a single large work surface
was set up as an island in the center of the room. The island was
custom-built by the hospital's plant-maintenance craftsmen.
"On one side of the island's countertop, we would later install
information system workstations for staff to use to look up file
locations and file availability," says Miller. "On the other side
of the island would be staff whose job is to assemble jackets and
make sure the contents are in correct order for hanging on an
alternator."
Once the workflow redesign was fully mapped, the fileroom
employees were given 3 weeks of intensive training so as to be able
to perform their job correctly. Afterward, however, each staffer
also received a 3-week training rotation in every other job
assignment in the room.
"The purpose of this was to help the staffers understand their
assigned duties in the larger context of everyone else's assigned
duties," says Miller. "This showed them how even a minor mistake at
their end could have an adverse ripple effect throughout the entire
room. It helped them be more diligent in their work as well as
encouraged them to function more cohesively as a team."
Importantly, Miller made it a point to keep the staff informed
at every step of the way before and during the fileroom
reorganization. Communicating with them took time and effort, but
proved itself an investment that paid huge dividends.
"No one felt disaffected by the changes," she says. "I explained
to them what I was finding in my analysis, what I thought needed to
be changed, what needed to be kept as is. I also sought their input
and feedback. All of this helped keep up morale. The last thing I
wanted to see was morale sink during this time of change, which is
something you have to carefully guard against whenever you take
away the familiar and replace it with something new."
Morale in general was kept high by staging small, in-office
celebrations each time a major milestone had been reached. For
example, the installation of the countertop island and getting it
operational was commemorated with a luau.
"I brought in a potted palm tree, we played island music, had
tropical-themed food," she says. "It was no big deal, but it made a
dramatic difference in the way the staff felt about the pains we
were going through during this time of change."
THEN CAME PACS
A mere month after starting the fileroom reorganization, Miller
began pulling together teams of personnel to serve as members of
PACS selection and implementation committees. The PACS team
included the IT operations manager, the IT networking technician,
the PACS/clinical information manager, the RIS administrator, a
radiologist, the radiology administrator from nearby Flowers
Hospital, which shared the same PACS, and Miller. So that each
member could do the best job possible in that capacity, Miller
supplied them with a wealth of information about PACS technologies
old, new, and still out on the horizon. She also provided
background information explaining what PACS would mean to the
hospital.
"I lobbied the hospital's information technology department to
be centrally involved because I knew we could not do a project the
size and magnitude of PACS without their help," Miller says. "It
was absolutely crucial to have them with us, right from the very
inception of the project."
After narrowing the field of prospective vendors to the seven
best, the PACS selection team drafted and issued RFPs. When the
replies came back, three vendors were eliminated from the list.
PACS team members then visited installed sites recommended by each
of the four vendors still in the running. A year-long examination
and comparison of performance, costs, and architecture features
brought the hospital to its ultimate winning bidder.
"Once our vendor was selected, implementation went quickly,"
says Miller.
Already installed at the hospital was a very large, tape-drive
data archive to facilitate development of an electronic patient
record system. This expensive archiveacquired about a year
earlierwas only being utilized to 25% of its potential.
"By incorporating it in our PACS project, we saved money at the
same time we increased the value of the hospital's previous
investment," she says. "The tape-drive data archive required some
upgrading in order to work with PACS. Even so, the cost of
upgrading was minor compared to what the hospital would have spent
on an all-new archive system."
The PACS team harnessed the underused archive by licensing an
additional 3,000 cells and adding 5 tape drives dedicated to PACS.
Two servers were added in front of the long-term archive for the
PACS data.
Network infrastructure too was already in place, another
savings. Reundant gigabit lines run to each of the three hospitals
and two imaging centers served by the PACS, configured in a circle
to provide backup in the event that one line gets cut. "We and our
PACS vendor brought in a network validation company to validate the
network to make sure it would be able to handle the PACS image
files," Miller divulges. "It found that all we needed was some
minor tweaking of the network, some switch changes, and the
addition of a few redundancy points."
PACS went live first in the ED. That was just days before
Christmas, 2002. Two months later, PACS was brought up throughout
the main radiology department. Less than 30 days afterward, the
entire hospital was online with PACS.
BIG WAIT LOSS
According to Gordon, the first phase of the PACS implementation
is now complete.
"It went very smoothly and is now deployed throughout the
hospital," he says. "We expect to start phase two in 2004. At that
time, we'll begin to extend PACS throughout the system to off-site
locations, including physician's offices and homes."
Originally, Miller planned a full phase-out of film and the
fileroom by gradually converting all past historical records to an
electronic format. She changed her mind after colleagues across the
country who had tread that same path warned her about the drawbacks
to that approach.
"It was economically infeasible, first of all," she says. "The
manhours required to digitize the films would have been enormous
and the number of digitizers needed to do that work would have
amounted to a very costly investment. Plus, digitized films are not
as flexible or as high quality as images that begin life as digital
output. So, film is going to be with us for quite a while. It was a
good thing, then, that we undertook the reorganization of the
fileroom."
The plan for film now is to select just certain categories for
digitizing, which will occur only after they have been read by the
radiologists. The remainder will stay on the shelves for 10 years
to satisfy HIPAA requirements and then be destroyed, Miller
notes.
So far, everything is working close to how Miller, Singer, and
Gordon envisioned. The one disappointment is that business is not
more brisk.
"The reorganized fileroom plus PACS make it possible for us to
handle appreciably more volume than ever, but the demand has not
materialized," says Miller. "That's because the market here is so
very competitive."
The upside is that the gains in efficiency have allowed the
radiology department to decrease backlog and open more time slots
on the patient schedule, which minimizes the chances that patients
will choose to take their imaging business elsewhere. Miller notes
that waiting time for MRI appointments when she first arrived at
Toledo Hospital ran 21 to 30 days. Now it is closer to 5. CT
studies entailed a wait of nearly 2 weeks; now patients enjoy
next-day appointments.
"Even if we had not gone to PACS, a reorganization of our
fileroom would still have been most advantageous for us," Miller
contends. "Fortunately, fileroom reorganization is not rocket
science. It is simply about building a good, strong foundation,
paying attention to details, and teaching personnel to perform the
tasks in a uniform way."
