Patient Safety
A Victory for ICU
Safety
The implementation of a critical care software system improves
information management in the ICU of a VA healthcare network.
The sharing of patient data such as hospital admissions
information, laboratory results, progress
notes, and imaging and authentication (access/
verify) data throughout any healthcare facility
is essential for maintaining the accuracy and efficiency of
clinical care. A seamless flow of information is especially
vital within the ICU, where seconds always count.
Among healthcare facilities of the Veterans Health
Administration, the proprietary in–house Veterans Health
Information Systems and Technology Architecture (VistA)
and the VA Computerized Patient Record System (CPRS)
cover approximately 80 percent of the documentation
needs of clinical care. However, the typical VA hospital
does not incorporate the ICU, anesthesia and post anesthesia
care unit (PACU) into this integrated information.
VA healthcare providers within the California–based
Sierra Pacific Network realized that to continue to be a
comprehensive, integrated healthcare system characterized
by exceptional accountability and healthcare value, they
needed to address immediately all three of these issues.
Together, they found a solution that integrated with VistA
and met the documentation needs and CPRS coverage desired
in the government’s move towards paperless patient
healthcare records.
Providing Critical Care for Vets
The VA Sierra Pacific Network is one of 21 Veterans Integrated
Services Networks in the Veterans Health Administration.
It serves over 1.2 million veterans residing in northern
and central California, northern Nevada, Hawaii, the
Philippines, and several Pacific islands including Guam and
American Samoa.
VA hospitals serve only veterans and certain specially
qualified dependents that meet a very specific and complex
set of criteria, mostly based upon injuries or illness
sustained while serving in the U.S. armed forces, so there
is no private pay or Medicare/Medicaid involvement with
the treatment they provide.
Among the healthcare providers within the VA Sierra
Pacific Network is VA Palo Alto Healthcare System, Palo
Alto, California. Maintaining one of the top three research
programs in the VA and affiliated with the Stanford University
School of Medicine, Palo Alto led the charge to
improve patient safety in the ICU with a complete overhaul
of their critical care documentation system.
The Search for a Viable Solution
Edward J. Bertaccini, M.D., associate professor of anesthesia
at the Stanford University School of Medicine and
staff anesthesiologist and intensivist at Palo Alto VA, was
involved with the search for a vendor solution, and later,
with its implementation. He says some of the primary
objectives for the new solution addressed the core issues
prompting the search for a replacement. Ease of use, configurability and maintenance were the main factors. “We
preferred a Windows–based solution using off–the–shelf
hardware,” says Bertaccini. “This meant better hardware
pricing and greater familiarity with the overall look and
feel of the software.” According to Bertaccini, both VA
San Francisco and Palo Alto already had electronic medical
records for their ICUs, but these required Unix–based
hardware solutions and dedicated specialists in Unix and
database administration. “This meant interacting with
people who had minimal to no [healthcare] background,”
says Bertaccini.
“We also preferred to have a system administrator
who was a nurse, so that this person would
have both a significant medical background as well
as a reasonable knowledge of Windows system
administration,” says Bertaccini. This type of
Windows–savvy healthcare professional was much
easier to find than a nurse with Unix training.
“Such a person was far easier to communicate
with regarding system preferences and configuration
issues.”
According to Bertaccini, the solution selection
process initially involved only three vendors, however there were volumes of decision criteria used to evaluate
prospective solutions. Input also came from a variety
of sources within the organization, including physicians,
nurses, respiratory therapists, pharmacists, IT and other
administration staff from the Veterans Integrated Service
Network (VISN) office. Palo Alto received demonstrations
from all three vendors through a combination of onsite
vendor representatives, as well as several site visits the
Picis selection team made to other institutions throughout
the country. “The final decision was made by a large group
comprised of representatives from each of the five hospitals
within the VISN, as well as people from our main office,”
says Bertaccini.
Deploying the New Recruit
The five integrated Veterans Affairs (VA) hospitals
purchased Picis’ ICU solution as a group to facilitate
implementation and to share ICU data in a common data
warehouse for analysis. VA Palo Alto was the first hospital
to go–live with Picis, which implemented the system for
30 ICU beds, followed by 18 beds at VA San Francisco,
and an additional 12 beds each in VA hospitals in Fresno,
California, and Reno, Nevada. These VA hospitals are
all tertiary care facilities with capabilities for significant
multispecialty care.
In August 2003, the five medical centers within the VA
Sierra Pacific Network (VISN 21) in northern California
and Nevada began implementation of CareSuite Critical
Care Manager to automate the documentation and workflow of 120 intensive care beds in all five hospitals. Additional
digital input boards had to be purchased to allow
for the interfacing of many bedside–monitoring devices
with the Picis workstation. Since implementing the new
intensive care unit information management system, Palo
Alto has experienced substantial gains in critical care
reporting efficiency. The healthcare system also utilized
the solution to train new staff members and clinicians to
streamline their workflows around the system’s bi–directional
information–flow operational capabilities. “It’s been
a very good teaching tool, as well as a management tool to
review everything that happens to the patient,” says Eran
Geller, M.D., director of critical care at VA Palo Alto
Medical Center.
Rounding–up Data at the Point of Care
The Critical Care Manager technology automatically
documents physiological data from ventilators, monitors
and medical devices, and successfully integrates critical
care data with the VA’s VistA system, helping to improve
the accuracy and efficiency of their clinical care. Physicians
use this data to highlight events and clinical results as each
resident presents his patients during rounds.
At VA Palo Alto Medical Center, approximately 100
nurses and physicians, plus another 40–50 residents and interns, currently use the Critical Care Manager solution.
Clinicians use wireless laptops mounted on carts to view
each patient’s complete clinical record during their medical
rounds. Because of the extensive integration the Picis solution
provides, physicians enter orders in VistA during their
rounds while reviewing a patient’s course rather than having
to wait until the end of rounds or having to leave rounds
to enter a patient order. “I definitely believe that having all
of this information at your fingertips during rounds helps
physicians make patient care more efficient and more accurate
because the data is right there and one can easily
verify the validity of the data
being presented,” says Geller.
Medical staff can now view all
of the electronic information
available on a patient—virtually
all information within the VA system—during rounds. They
use the VistA CPRS interface to view the patient’s chart,
and the Stentor Radiology package to look at X–rays, CT
scans and MRIs. Finally, all of these solutions are accessible
from remote locations via secure network connections.
This has helped clinicians provide more thorough care of
VA hospital patients even during off hours.
Key Applications
Physicians are using Critical Care Manager to show
trends of physiological abnormalities that have occurred to
a patient in the ICU such as graphed changes in a patient’s
blood pressure and heart rate that occurred overnight.
The ICU pharmacists also use a wireless laptop to
concurrently review all medications for each patient in
VistA to make sure they are appropriate and there are no
untoward interactions between drugs. Seamless access
is achieved because the critical care manager software
and VistA are viewable on the same screen and share a
single sign on.
Intensive care data is now being transmitted from Critical
Care Manager back to VistA every 24 hours where the
official, legal record of the patient is kept up to date. This
data sharing provides the hospital with comprehensive
automation, a complete electronic patient record and a
significant pool of data for analysis and reporting. This also
enables physicians to look at the patient’s VistA record
(EKGs, X–rays, CT scans, MRI’s) and Picis data all on the
same screen.
Achieved Solution Objectives
Since the implementation of the Picis solution, the
VA Palo Alto Medical Center has realized substantial improvements
to its critical care information management
processes. The significant advantages of the interfaces
between the Picis system and VistA are the primary reason
VA Palo Alto replaced its existing critical care information
system with Critical Care Manager. Some of these advantages include a quick acceptance and buy–in of the
new solution by nurses and doctors because most found
the software easy to use. There is no formal in–service for
physicians, either—another benefit since this eliminates the
customary downtime spent learning a new system—time
that would otherwise have been spent providing patient
care. Physicians and staff also appreciate that Critical Care
Manager screens can be configured to meet user needs.
They customized screens at Palo Alto to resemble screens
staff had used in the past, which made the transition to the
new system comfortable and quite rapid, increasing staff
satisfaction with the system.
Forward–looking Applications
Currently, VA Palo Alto and San Francisco VA Medical
Center are utilizing Critical Care Manager to share their
results for data analysis. Picis’ advanced data extraction tool
automatically exports all ICU data into a comprehensive
data warehouse where researchers evaluate best practices,
compare data between centers and study clinical outcomes.
Dr. Gerard Ozanne, at the San Francisco VA, and Dr.
Geller continue to work closely with Picis and VA personnel
to not only implement a clinical information system,
but also to mine their ICU data for correlations in quality
of care and outcomes. Ozanne and Geller have already
identified several clinical parameters that were previously
unknown which appear to have a significant effect on patient
mortality post discharge from the ICU. Geller says,
“When you see the whole picture, you sometimes pick up
on a different understanding of the data because you have
all of the information in front of you.”
They are exploring this correlation further to determine
its impact on patient care and to develop possible
preventative steps.
