Primary Care Office InSite (PCOI) is a Web-based
intranet application that provides ready access to a
collection of information useful in primary care. The
PCOI Web site was developed by, and is widely used
within, the Massachusetts General Hospital (MGH)
and its affiliated community practices. Over 1600
users logged 60,000 separate sessions in the past
year. The site contains clinical practice guidelines,
patient educational material, drug prescription and
cost information and referral information, all
designed for use during routine patient care activity.
This paper discusses the problems encountered and
the lessons learned during an ongoing experiment to
disseminate PCOI via the Internet to four distant and
very different ambulatory care sites. None of these
sites (a rural community hospital, a city-wide health
care network, an inner -city general hospital, and an
Indian Health Service hospital have the resources to
develop such an application internally.
INTRODUCTION
One of the recommendations from the Institute of
Medicine (IOM) report on improving the delivery
of medical care was to utilize information
technology in daily practice to increase the use of
scientifically valid decision-making.1 Studies have
repeatedly shown that the information needs of
primary care physicians (PCPs) are not being met2,
3
. While there is a wealth of information available
on the Internet, this information is not readily
available and not optimally organized for use
during daily patient care.
The information needs of primary care physicians
and their information-seeking behaviors have been
widely studied. The findings have been remarkably
similar among clinicians at different levels of training
and practice settings and across different cultures. An
4
excellent review by Smith summarized a group of
studies showing that the questions are often complex
and multidimensional, and that doctors are most
likely to seek answers to their questions from other
doctors. Most of the questions generated by doctors
can be answered, using electronic sources, but this is
time consuming and expensive—and demands
information skills that many doctors lack.
The typical primary care patient visit lasts 10-15
minutes. During that brief time, the PCP must review
the patient’s chart, take a history, perform the
necessary physical exam, discuss his/her findings,
write prescriptions, fill out a billing/encounter form
and write a note in the chart. At the same time, he or
she must try to fulfill the needs of the patient for
emotional support and understanding. It is not
surprising that PCPs rarely search external sources
for information. Even though many would agree that
it is not optimal, mo st physicians rely on their
personal knowledge and memory rather than pub5
lished guidelines or the medical literature . As
McKibbon et al note, “Because of other demands on
their time, clinicians preferred to take less than two
6
minutes per question to find answers .”
Many of the clinical questions that go unanswered
during daily practice can be answered from the
literature. In an Oregon study, medical librarians
were asked to use only online resources to answer 60
PCP-generated questions. Time or cost res trictions
were not applied to the searches. These “gold
standard” searches averaged 43 minutes in length and
$27.37 in cost. The clinicians judged the answers
relevant in 56% of cases, and said that the
information provided a "clear answer" to 46% of their
7
questions . The value of the trained searcher is not
under question; however, the time and cost involved
makes this approach impractical. There has been
increasing attention to developing guidelines that
promote evidence-based medicine, but less attention
to mechanisms to transfer evidence into clinical
practice and to keep up with the ever-increasing
amount of clinical trial data. The reality is that it is
nearly impossible for any human-based information
service to provide cost-efficient, timely information
under the two-minute deadline needed to satisfy a
PCP. Shifting the work of answering questions that
arise in daily practice to a computer-based
information resource may provide the Just-in-Time
8
information desired at the point of care.
BACKGROUND
In 1996, the Massachusetts General Hospital
(MGH) began a number of operation improvement
AMIA 2003 Symposium Proceedings − Page 61
initiatives to identify and implement changes that
would improve patient care, increase patient
satisfaction, and promote cost-effective decisionmaking. One initiative of the General Medicine
Unit was the development of evidence-based
clinical guidelines focused on clinical relevance
and potential to improve medical care efficiency
and effectiveness. The guidelines, developed by a
working group of the MGH adult medicine
primary care practices, were not meant to represent
hard and fast rules; clinical judgment is required in
applying these guidelines to any individual patient.
The philosophy of the work group was that time
and resources are limited in primary care practice;
therefore, selection and prioritization of
recommended care guidelines should be based on
the strength of direct evidence of benefit from
clinical research. Individual guidelines were sent
to MGH primary care and specialty content
experts for review and comment; however, no
clinicians outside the work group were asked to
approve or endorse these guidelines. The work
group considers it to be an ongoing responsibility
to review and revise the existing guidelines as new
evidence becomes available.
The guidelines were initially distributed to MGH
adult primary care clinicians in hard-copy form but
we soon realized that the size of the notebook
would inhibit physicians from accessing this
material in their routine patient care practice and
that it would be difficult to distribute new or
revised material in a timely fashion. Therefore we
shifted the distribution from a printed binder to the
MGH intranet taking advantage of Web
technology to facilitate indexed searching, ease of
navigation, and linking of related patient
instruction materials to clinical guidelines to better
respond to the point-of-care physician information
needs. There are three different approaches to
provide Web-based clinical information: providing
pointers to information resources available over
the Internet; providing electronic versions of
commercially available standard medical reference
sources; and creating a local information repository which combines focused, patient-centered
knowledge and patient-specific recommendations
and resources that facilitate the informat (...truncated)
