Benefits
of a PACS
Better Quality
of Service and Cost Savings
- Improved
Diagnostic Capabilities – Diagnostic workstations
with powerful and easy to use tools enable radiologists to detect
more information regarding patients.
- Improved
Workflow
– The process of handling patients and their information
is much more efficient.
- Reduced
X-ray Retakes – The CR hardware reduces the number
of retakes due to under or overexposure.
- Fewer
or No Missing Records – Misplaced films are a major
problem for hospitals.
- Availability
– PACS makes it easy and quick to share patient studies
with those who need to see them: radiologists, physicians within
the hospital, referring physicians, clinicians, and specialists
even at distant locations.
- Security
– PACS facilitates enforcing hospital privacy policies and
procedures through user accounts, logging, and encryption - ensuring
that only those authorized to see patient information have access
to it.
- Reduced
Film Storage Costs – Both space required for storage
and labor for filing and retrieving will diminish with no new
films being added to the physical archive.
- Improved
Timeliness in Record Retrieval – Information comes
up almost instantaneously, as opposed to clinicians having to
sometimes look all over the facilities trying to find films.
- Onsite
Redundant Storage – Two servers on site mirror
up to two years of stored images.
- Disaster
Recovery – NWPACS will maintain duplicate copies
of all patient studies off site for quick disaster recovery and
long-term storage, a feature not feasible with physical film.
- Teleradiology
– Radiologists can review patients’ studies remotely
– home, etc.
Reasons
for PACS - Information From Mayo Clinic
Departments should not forget, in their deliberations over the implementation
of PACS, that the use of film is accompanied by a significant ongoing
cost. Film has its virtues, but it remains very expensive. Failure
to invest in PACS constitutes a commitment by omission to the present
and future costs of film storage. An excellent study has examined
the 7-year costs of the storage and handling of film (for adult
patients, studies are retained for 7 years). The estimate of King
et al at the Mayo Clinic, Rochester, MN, was $15.82
per examination. Of this cost, $6.25 was attributable to film for
a four-sheet examination; for many modalities such as MRI, however,
more sheets of film will be used. For supplies associated with processing
and packaging, $1.46 was spent. Personnel costs for film handling
were $5.91 within the radiology department and $2.20 outside it
(spent, for example, when nurses or clerical staff must attempt
to locate missing films).
Even at $15.82,
the investigators noted that their cost estimate was probably lower
than the real costs encountered at other institutions. The Mayo
Clinic performs a million radiology examinations per year and estimates
that maintaining its film library costs $16 million per year. This
can be extrapolated to other institutions at a rate of $1.5 million
or more per 100,000 examinations. There is a significant cost associated
with every film study performed today, and that cost will continue
in force as long as the film is retained by the institution.
For this reason,
PACS represents a classic tradeoff: today’s equipment costs
versus ongoing costs for film, supplies, and personnel. Those proposing
PACS implementation, however, should exercise caution in claiming
future savings for which they will be held accountable by their
administrators. Realistic business and operational plans for achieving
these savings should be in place before the elimination of film-associated
costs is counted upon to offset the cost of PACS.
