Do not underestimate the importance of properly educating staff to identify problems, prevent system failures, and keep operations running smoothly.
One of the last items that many facilities consider during the
purchase of a picture archiving and communications system (PACS) is
training for those who will become PACS administrators (and, quite
often, deciding who will assume that role). As PACS implementations
continue to expand into the imaging-center and small-hospital
segments of the PACS market, training can smooth the transition. At
large hospitals, maintaining a staff of dedicated PACS
administrators and technicians (or vendor-supplied on-site
personnel) is considered part of the cost of doing business, but
smaller hospitals and imaging centers cannot afford a separate
staff to maintain a PACS. In this situation, facilities typically
choose an already busy technologist or office administrator to
perform routine administrative tasks. Although this is not the most
desirable situation, it can be, with training, a viable one.
Ideally, an information-technology specialist and a radiologic
technologist will share administration responsibilities, with each
performing tasks specific to his or her realm of expertise. The
information-technology specialist, for example, would manage the
day-to-day system-related requirements, and the radiologic
technologist would manage patient-related information. In the event
that only one or the other is available, management of the system
can be performed adequately by either.
Whoever is given the role of PACS administrator must understand
that daily maintenance is a fact of life. Every PACS must be
monitored. In a large facility with dedicated PACS staff, the task
of monitoring can be easily assigned; once trained to understand
the requirements of the system, the PACS staff will meet them
reliably. An imaging center, however, quite often relies on a
technologist to perform daily maintenance. Without proper training
for this individual, daily PACS requirements will not be met; the
first sign of a problem is likely to be a system failure requiring
corrective action, rather than a system message concerning some
difficulty that can be corrected before a system failure occurs.
Regardless of the size of the facility, reliance on the PACS
administrator should not be underestimated.
Training should encompass the normal day-to-day activities
required of the administrator and should familiarize trainees with
normal system-status messages so that, in the event of a failure,
the administrator can take appropriate action (be that rerunning a
backup or placing a service call). Regardless of the error, early
intervention by trained personnel will minimize the impact of a
failure on the enterprise.
Daily Tasks
No matter what size the facility is, there are tasks that need
to be performed for any PACS: database backup, image-data
archiving, and operational checks of system hardware. If performed
as part of a maintenance plan, this routine administration requires
only a few minutes per day. An equally important task is the
management of demographic data. Inaccuracies in demographic data,
such as a misspelled patient name or incorrect identification
number, can lead to lost images and can affect the ability to
identify and retrieve data quickly. Even in an environment having
an integrated radiology information system (RIS), where Digital
Imaging and Communications in Medicine (DICOM) Modality Work List
is employed, patient demographics will require manual correction at
some point. Locating and correcting data on examinations that have
been assigned to the wrong patient, or for which the patient
information is inaccurate, can affect whether an examination can be
found (or slow the reading process while the examination in
question is located and verified). Although not considered part of
routine system maintenance, these tasks occur daily. Administrators
should be familiar with the correction process. Editing patient
demographics and reparenting (reassigning examinations from one
patient to another) are simple tasks, but can result in lost images
if improperly performed. Demographic corrections should be
performed as soon as an error is reported in order to keep the data
as accurate as possible.
Many facilities overlook the fact that the PACS role encompasses
not only the archiving of images, but their distribution, as well.
This means that familiarity with diagnostic workstations and
distribution systems such as web servers and teleradiology devices
will need to be included in the PACS administrator's repertoire. In
both smaller and larger facilities where staffing is limited, a
good relationship with the manufacturer can provide a source of
technical expertise to bolster the existing staff.
Integration
When a PACS is implemented, it is generally with long-term
archiving and distribution as primary objectives. With this in
mind, determining work flow is critical to configuring the system
for each facility. Some questions to consider during this stage are
shown in the table below. The answers can then be fleshed out and
used to provide a road map for installation and integration. The
administrator should be familiar with this map, as it will
eventually become the basis of a site profile.
Even with limited resources, a vendor-supplied project manager
who is available during the initial planning and installation
phases can ask the necessary questions, help provide their answers,
and assist the facility in the development of a work-flow plan.
Quite often, a project manager will continue to work with the
facility and assist it in expanding its PACS long after the initial
installation is complete. This is especially valuable when the PACS
budget is limited and the system is to be installed incrementally.
Planning the growth of a PACS to take place over several years and
multiple phases is not uncommon, but if the purchases are not made
logically (or if one phase is not completed properly), the results
are wasted time and money, along with a work flow that is more
hindrance than help. Knowing how to scale the installation, and
which steps to take in what order, will contribute greatly to a
smoother installation and integration process.
After installation, the training process should include all
administrators, both technical and nontechnical. As part of the
installation, training should cover the basic requirements
necessary to keep the PACS running properly. Later, more advanced
training should cover a finer level of detail, providing designated
administrators with more advanced tools. These include the ability
to configure certain aspects of their systems so that, if a
facility opts for a higher level of autonomy, it can manage the
details of connectivity, routing, and viewing preferences without
having to rely on an outside party.
Procedural Volume
Volume is a significant factor in determining how many people
should be involved in the administration of a PACS. A facility
performing 300,000 examinations per year obviously will require
more administration time than one performing 20,000 examinations
will need. Although the larger facility may have a PACS staff of
one or two information-technology specialists and one or two
technologists whose sole responsibility is the day-to-day
management of the system, the smaller facility may have only a
single information-technology specialist or technologist to perform
the same tasks. This administrator requires the same level of
training as the administrators at the large facility. The single
administrator may be the only on-site person who has technical
familiarity with PACS; since this person may also be filling the
role of technologist or may have other responsibilities, the more
familiar with the usual tasks he or she is, the more quickly he or
she can perform them and return to duties unrelated to PACS.
The impact that training has in the large facility should not be
underestimated, however, even if that institution has dedicated
personnel to maintain the PACS. If a significant portion of the
information received requires correction, having the knowledge and
the tools to correct it quickly is critical to keeping pace with
examination volume. Whenever possible, integration with the RIS and
use of DICOM Modality Work List should be employed as sure ways to
reduce inaccuracy and increase performance.
Since a PACS can only manage the information that it has,
understanding that data may be sent to the PACS from any number of
devices throughout the enterprise is important. Being familiar with
site work flow and network topology will greatly increase the
administrator's ability to respond to crisis and noncrisis
situations alike.
Regardless of the size and procedural volume of a facility,
training is a system requirement that is often overlooked. The
inability to identify problem examinations quickly or perform daily
maintenance can have a negative impact on the ability of a PACS to
perform its key function: getting images to the radiologist.
Centralized reading, reporting, and distribution are key goals for
many facilities. Without trained personnel who understand the
management, integration, and maintenance of these different
systems, it is unlikely that they will function together smoothly,
and this can even be detrimental to the process of reading images.
No matter how many administrators an enterprise has or how high its
examination volume may be, training is required to get the highest
level of performance from PACS.
