<a name="head2"></a><h2>Depression and coexisting illnesses should be treated
|
|
together to reduce costs and improve outcomes</h2>
|
|
<p>Older primary care patients who are depressed incur greater average charges for diagnostic tests
|
|
than patients who are not depressed. These higher charges are not due to depression, per se, but
|
|
instead can be attributed to the greater burden of coexisting medical illnesses borne by depressed
|
|
patients compared with patients who are not depressed, according to Christopher M. Callahan,
|
|
M.D., of the Regenstrief Institute for Health Care, lead author of a recent study.</p> <p>
|
|
|
|
Older persons, in particular, are more apt to suffer from coexisting illness, to be functionally
|
|
impaired, or to receive medication that can lead to symptoms of depression or mask existing
|
|
depression, according to the study, which was supported in part by the Agency for Health Care
|
|
Policy and Research (HS07632 and HS07763). Thus, improved treatment of mental illness is not
|
|
the answer to reducing excess use of medical services by patients with mental disorders. Instead,
|
|
primary care physicians and mental health specialists need to address organic and psychiatric
|
|
illnesses simultaneously, notes Dr. Callahan. </p>
|
|
|
|
<p>Dr. Callahan and his colleagues compared the amount and charges for inpatient and outpatient
|
|
diagnostic testing for 3,767 patients 60 years of age and older who completed testing on the
|
|
Centers for Epidemiologic Studies Depression Scale (CES-D) during routine office visits at a
|
|
primary care group practice from 1991 to 1993.</p><p>
|
|
|
|
The researchers found that depressed patients were more apt than nondepressed patients to have
|
|
nonpsychiatric medical problems and more visits to the outpatient care center (nine visits vs. eight
|
|
visits, respectively), to use the emergency department (52 percent vs. 40 percent), and to be
|
|
hospitalized (22 percent vs. 17 percent). These patients also incurred $200 more in diagnostic test
|
|
charges for a 1-year period ($583 vs. $387) than nondepressed patients—a large sum if
|
|
calculated
|
|
for an entire population of older adults over several years. The 54 percent difference in charges,
|
|
mostly for clinical pathology (for example, routine blood and urine tests), persisted into the
|
|
second year.</p>
|
|
|
|
<p>See "Association of symptoms of depression with diagnostic test charges among older adults," by
|
|
Dr. Callahan, Joseph G. Kesterson, M.A., and William M. Tierney, M.D., in the March 15, 1997,
|
|
issue of <em>Annals of Internal Medicine</em> 126, pp. 426-432.</p>
|
|
<a name="head3"></a><h2>Primary care physicians are more likely to recognize
|
|
depression in women and more educated patients</h2>
|
|
<p>Primary care physicians often fail to recognize depression when it is present in their patients, yet
|
|
they are less likely to miss it in women and more educated patients than in men and less educated
|
|
patients, according to a study supported by the Agency for Health Care Policy and Research
|
|
(HS08029 and HS06167). The study shows that depressed women are twice as apt to be
|
|
diagnosed as such than depressed men and that for each additional year of education, the odds
|
|
increase by 24 percent that a patient will be correctly diagnosed as depressed. </p> <p>
|
|
|
|
Health status measures, such as level of energy and physical and social functioning, declined
|
|
among patients in this study as their depression symptoms increased. Therefore, Edward J.
|
|
Callahan, Ph.D., and Klea K. Bertakis, M.D., M.P.H., of the University of California, Davis, and
|
|
their colleagues suggest that clinicians incorporate health status measures when assessing primary
|
|
care patients. When a patient demonstrates an unexpectedly sudden decline or progressive
|
|
deterioration in health status scores that is not accounted for by a physical illness or other medical
|
|
problem, the clinician should suspect a mental disorder. The clinician can then use other
|
|
diagnostic techniques and instruments such as the Beck Depression Inventory (BDI) to aid in the
|
|
correct diagnosis.</p>
|
|
|
|
<p>The researchers gathered data from 1990 to 1993 on 508 consecutive new patients who were
|
|
randomly assigned to 105 family practice and general internal medicine residents. Each physician
|
|
saw an average of five patients. The patients completed the BDI, which measures the presence
|
|
and severity of 13 symptoms of depression, and the SF-36 health status questionnaire. The
|
|
researchers compared the test results, which were not revealed to the physicians, with the
|
|
presence or absence of depression diagnosis on the patients medical charts.</p> <p>
|
|
|
|
Physicians made a chart notation of depression for only 28 percent of the 130 moderately or
|
|
severely depressed patients (BDI score of 9 or more). The physicians were more apt to correctly
|
|
diagnose depressed women and more educated patients, even after adjusting for differences in
|
|
health status, BDI scores, and other factors. Age and race did not influence recognition of
|
|
depression by the primary care physicians.</p>

|

<a name="head4"></a><h1>HIV/AIDS Research</h1>
|
|
<a name="head5"></a><h2>Primary care physicians fail to identify half of patients
|
|
at risk for HIV infection</h2>
|
|
<p>Primary care physicians do not routinely assess patients for HIV risk, even when the patients have
|
|
obvious risk behaviors for HIV, such as multiple sex partners or intravenous drug use. In fact,
|
|
they fail to identify risk behaviors for HIV infection or include HIV in the diagnosis of more than
|
|
half of the patients in whom active HIV infection should be considered, according to a study
|
|
supported by the Agency for Health Care Policy and Research (HS06454).</p> <p>
|
|
|
|
Paul G. Ramsey, M.D., principal investigator, and other researchers randomly selected 134
|
|
primary care physicians to examine standardized patients (SPs, individuals trained to enact
|
|
specific case presentations) to assess overall clinical skills, as well as the physicians skill at
|
|
identifying and managing HIV infection. In a day of testing, physicians saw 13 to 16 SPs with
|
|
diverse case presentations. Nine SPs were at high risk for HIV infections with unidentified risk
|
|
behaviors for HIV, which they offered if asked. However, only 12 percent of at-risk SPs were
|
|
asked about their history of sexually transmitted disease, which increases the risk of HIV
|
|
infection; 49 percent were asked if they were sexually active; 15 percent were asked about the
|
|
number of sexual partners they had; 39 percent were asked about injection drug use; and 50
|
|
percent of at-risk male SPs were asked about sex with other men. </p>
|
|
|
|
<p>Individual physicians initiated screening in at least one of the five risk assessment categories with
|
|
an average of 60 percent of at-risk SPs they saw. General internists initiated screening for a higher
|
|
percentage of SPs than family practitioners (67 percent vs. 55 percent of SPs seen), and
|
|
physicians with the most HIV experience initiated screening more often than physicians with the
|
|
least experience (69 percent vs. 55 percent of SPs seen).</p> <p>
|
|
|
|
Primary care physicians are inconsistent and sporadic in screening for and identifying HIV risk
|
|
factors, concludes Marjorie D. Wenrich, M.P.H., of the University of Washington, Seattle, the
|
|
lead author of a recent paper describing these findings. She points out that standardized screening
|
|
techniques are needed to identify persons at risk for HIV. One approach would be the inclusion of
|
|
specific questions about HIV risk behaviors in standard medical intake forms.</p>
|

<a name="head6"></a><h2>Many health care providers do not test TB patients for
|
|
HIV infection as recommended</h2>
|
|
<p>Nearly half of urban tuberculosis (TB) patients in the United States are also infected with the
|
|
human immunodeficiency virus, or HIV. But despite recommendations to test all TB patients for
|
|
HIV, many health care providers choose to test only those they perceive to be at risk of HIV
|
|
infection, according to a study supported in part by the Agency for Health Care Policy and
|
|
Research (National Research Service Award training grant T32 HS00046). It shows that
|
|
one-third of TB patients in AIDS-dense areas of Los Angeles were not tested for HIV, and that
|
|
provider choice not to test, rather than patient refusal to be tested for HIV, was the critical
|
|
variable.</p><p>
|
|
|
|
Physicians tested mostly persons with HIV risk factors, but at least 2 to 7 percent of low-risk
|
|
patients were infected with HIV. Thus, the opportunity to diagnose and treat HIV coinfection
|
|
may be missed in a substantial number of TB patients, conclude the California researchers. They
|
|
reviewed the medical charts of 500 patients at 20 health centers, who were listed in the Los
|
|
Angeles County tuberculosis registry in 1993, to document whether or not the patients had been
|
|
tested for HIV infection. </p>
|
|
|
|
<p>The researchers found that females were 42 percent less likely to have been tested compared with
|
|
males, and persons aged 20 to 49 years were more apt to be tested than younger and older
|
|
persons. Patients with HIV risk factors were nearly nine times more likely to be tested for HIV
|
|
than patients without risk factors. Overall, physicians tested only 63 percent of TB patients for
|
|
HIV infection. Patients of private practitioners were 68 percent less likely to have been tested
|
|
than were patients treated by public health authorities. This may be because public health
|
|
providers are better educated about the relationship between TB and HIV or that they have a
|
|
stronger commitment to infectious disease control, suggest the researchers. They conclude that
|
|
further education of health care providers is essential to achieve universal HIV testing among TB
|
|
patients.</p><p>

<a name="head7"></a><h1>Special Populations</h1>
|
|
<a name="head8"></a><h2>Homeless individuals living in congested urban areas
|
|
are at high risk for TB infection</h2>
|
|
<p>Homeless persons living in crowded shelters are vulnerable to infection with tuberculosis (TB).
|
|
They come into contact with former prison inmates, substance abusers, and others who are at high
|
|
risk of already being infected, and their often crowded quarters make it easier for the TB bacteria
|
|
to pass into their lungs via air droplets when infected persons cough or sneeze. As a result, about
|
|
one-third of the homeless persons in Los Angeles and San Francisco are infected with TB; this
|
|
translates to a prevalence rate that is three to six times greater than the 5 to 10 percent prevalence
|
|
of TB skin test positivity in the general adult population.</p> <p>
|
|
|
|
A recent study, supported in part by the Agency for Health Care Policy and Research (HS06696),
|
|
examined factors that increase the risk of homeless persons becoming infected with TB. It found
|
|
that 40 percent of homeless persons in the urban Skid Row area of Los Angeles had positive TB
|
|
skin tests compared with 14 percent of homeless persons in the suburban Westside area (an
|
|
overall 32 percent prevalence). This was probably due to the crowded conditions in the urban
|
|
area, explains lead investigator Lillian Gelberg, M.D., M.S.P.H., of the University of California,
|
|
Los Angeles, School of Medicine. </p>
|
|
|
|
<p>The researchers performed TB skin tests on 260 homeless adults in shelters, soup lines, and
|
|
outdoor locations in two areas of L.A. Compared with persons living in traditional housing (hotel,
|
|
apartment, or house), persons living in a shelter or institution were four times more likely to have
|
|
a positive TB test. Individuals living in limited shelters—such as an abandoned building, car,
|
|
or
|
|
all-night theater—were 3.5 times more apt to test positive, and those living on the streets
|
|
were 2.5
|
|
times as likely to test positive.</p> <p>
|
|
|
|
The likelihood of skin test positivity increased dramatically after an individual had been homeless
|
|
for 10 years (quadrupling the risk) but was relatively constant up to that point. Older homeless
|
|
persons were more apt to test positive, with persons aged 18 to 30 years showing a prevalence of
|
|
19 percent; those 31 to 40, 27 percent; and those over 40, 44 percent. Although alcohol and drug
|
|
abuse and prison history have been shown to be predictors of TB in the general population, they
|
|
were not important predictors of TB test positivity in this study.</p>

<a name="head9"></a><h1>AHCPR News and Notes</h1>
|
|
<a name="head10"></a><h2>From the Administrator</h2>
|
|
<p>I would like to take this opportunity to introduce myself, and tell you how pleased I am to be
|
|
working with you as Administrator of the Agency for Health Care Policy and Research. During
|
|
my years as a health services researcher, I was impressed with the high caliber of the research
|
|
supported by AHCPR and conducted by researchers on its staff. This continues to be true as I
|
|
learn more about the Agency from the inside.</p><p>
|
|
|
|
AHCPR is the nation's lead Agency in ensuring that there is a scholarly and scientific foundation
|
|
for a rapidly changing health care system. However, we cannot succeed without your expertise
|
|
and dedication to excellence in research. Our shared goal is to enhance the way health care
|
|
services are organized, financed, and provided. We want to improve the care patients receive and
|
|
help them take responsibility for their own health and health care.</p>
|
|
|
|
<p>My agenda is still evolving, but one of my priorities is to ensure that AHCPR continues to
|
|
enhance the quality of health care and its value by meeting the needs of the health services
|
|
research community. One of the most critical needs is to ensure that we continue to build capacity
|
|
for health services research. We already are expanding our efforts to nurture the careers of new
|
|
investigators beyond our dissertation grants program and our National Research Service Awards.</p>
|
|
<p>I also plan to work with you to create centers of excellence where teams of established
|
|
researchers can do state-of-the-art work, and where young researchers can be trained. We already
|
|
have excellent examples in our Patient Outcomes Research Teams (PORTs), upcoming
|
|
Evidence-based Practice Centers, and MEDTEP Minority Research Centers. </p>
|
|
|
|
<p>We also will continue to play a critical role in fostering innovation among researchers in our field.
|
|
To that end, AHCPR is carefully weighing the balance between the funding of
|
|
investigator-initiated research and targeted research. We are reviewing the criteria we use in
|
|
targeting funds to particular areas and will be seeking funding partners for targeted research
|
|
projects. In addition, AHCPR will be working with you to translate health services research
|
|
findings into a language that can be used by decisionmakers at all levels, from patients, clinicians,
|
|
and health systems to the Federal and State governments. I firmly believe that we must
|
|
disseminate our findings and do everything we can to ensure that they are applied or at least
|
|
considered so that the public may benefit from the work we do.</p> <p>
|
|
|
|
I encourage you to let us know how we can do a better job of communicating and working with
|
|
you and of providing the basic tools and leadership needed to ensure that health services research
|
|
can meet the challenges that lie ahead. Please send your comments and suggestions to the
|
|
<a href="about.htm">Managing Editor</a>, <em>Research Activities</em>. We will let
|
|
you know in an upcoming issue of <em>Research Activities</em> about the comments and recommendations we receive and how we plan to address them. </p>

make available a full range of current guidance on treatments for specific medical conditions.</p><p>
|
|
|
|
Under the plan, AHCPR, the American Association of Health Plans, and the American Medical
|
|
Association will work jointly to develop the new guideline clearinghouse. It is anticipated that
|
|
AHCPR will award a contract later this year for the technical work to establish the NGC. The
|
|
target date for launching the new Internet clearinghouse site is fall 1998.</p>
|
|
|
|
<p>Internet technology makes it possible to provide rapid access to the latest information on medical
|
|
treatments. According to AHCPR Administrator John M. Eisenberg, M.D., the NGC will provide
|
|
access to the widest selection of guidelines available from public and private organizations by
|
|
establishing an independent, interactive Web site, accessible by using any standard Web browser
|
|
or through the Web sites of the three collaborating organizations.</p><p>
|
|
|
|
The development and use of clinical practice guidelines have grown markedly in the past 5 years.
|
|
However, many existing and potential guideline users have difficulty gaining access to and
|
|
keeping abreast of the many clinical practice guidelines currently in use. In addition, existing
|
|
guidelines often differ in their development and content, further complicating their use. To help
|
|
address these issues, the NGC Web site will:</p>
|
|
<ul>
|
|
<li> Contain standardized information for thousands of guidelines such as title, sponsoring
|
|
organization, author(s), and methodology used.</li>
|
|
<li>Provide guideline abstracts and where possible the full text of guidelines.</li>
|
|
<li> Compare and contrast the recommendations of guidelines on similar topics, and provide
|
|
summaries covering major areas of agreement and disagreement.</li>
|
|
<li> Have topic-specific electronic mailing lists to enable registered users to communicate with
|
|
one
|
|
another on guideline development, dissemination, implementation, and use. </li>
|
|
</ul>

|
|
<p>The Agency for Health Care Policy and Research has released an update to the clinical
|
|
performance measures database first released last year. CONQUEST 1.1, the Computerized
|
|
Needs-Oriented Quality Measurement Evaluation System, has been changed to make it more
|
|
user-friendly and compatible with a variety of operating systems.</p><p>
|
|
|
|
<a href="/qual/conquest.htm">CONQUEST</a> is a quality improvement software tool that helps users identify, understand,
|
|
evaluate and select measures to assess and improve clinical performance. It summarizes
|
|
information on approximately 1,200 clinical performance measures developed by public- and
|
|
private-sector organizations to examine the quality of clinical care. CONQUEST describes
|
|
measures using a common language and provides a research short-cut by identifying specific types
|
|
of measures that may be modifiable or adaptable for a users own unique needs. If modified, the
|
|
measures should be retested for validity and reliability.</p>
|
|
|
|
<p>Organized in an easy-to-use format, CONQUEST consists of two interlocking databases—a
|
|
Condition Database and a Measure Database—that allow users to target specific conditions
|
|
or
|
|
measures. The Condition Database includes information on 52 clinical conditions; the Measure
|
|
Database contains information on the 1,200 measures contained in 53 measure sets. Users can
|
|
produce preprogrammed or custom reports and add measures and conditions to the database.</p><p>
|
|
|
|
The 1.1 version functions as a run-time program in Windows® 3.1 and higher, including Windows®
|
|
95. Microsoft®'s Access® 2.0 is no longer required but still may be used to complete keyword
|
|
searches or add to the database. The User's Guide has been updated with clearer instructions and
|
|
an index.</p>
|
|
|
|
<p><a href="/qual/conquest.htm">CONQUEST</a> may be downloaded from AHCPR's Web site. The diskettes (AHCPR Publication No.
|
|
97-DP01) and the <em>User's Guide</em> (AHCPR Publication No. 97-R001) also are available free from
|
|
the <a href="https://www.ahrq.gov/research/publications/order/order-research-activities.html">AHCPR Publications Clearinghouse</a>.</p><p>
