Introduction
The Agency for Healthcare Research and Quality (AHRQ) released in 
    December 2003 the first
    National Healthcare Quality Report (NHQR) and National Healthcare
    Disparities Report (NHDR) on behalf of the U.S. Department of Health and 
    Human Services  (1,2). In this commentary, we
    summarize the main findings of the reports on preventive care for both
    primary prevention of disease and secondary prevention of increasing acuity
    of existing disease and discuss the implications for quality measurement and
    improvement efforts. 
Federal partners within the U.S. health care system have recently focused
    on increasing the use of preventive care services. Tommy G. Thompson,
    Secretary of Health and Human Services, issued a challenge in April 2003 at the
    launch of the Steps to a HealthierUS 
    national initiative: 
"Approximately 95% of the $1.4 trillion that we spend as a nation on
    health goes to direct medical services, while approximately 5% is allocated
    to preventing disease and promoting health. This approach is equivalent to
    waiting for your car to break down before you take it in for maintenance. By
    changing the way we view our health, the Steps initiative helps move
    us from a disease care system to a true health care system." (3) 
 
Good quality preventive care holds the promise of greatly reducing the
    nation’s health care costs and overall burden of disease. Numerous studies
    and reports have examined the general quality of preventive care services in
    the United States (4-7). Others have explored the performance of the U.S.
    health care system in delivering specific preventive care services such as
    immunizations (8,9), cancer screening (10-12), and cholesterol and blood
    pressure screening (13-15). 
The NHQR and NHDR provide the first national baseline views of the
    quality of health care services and of differences in how at-risk groups in
    America use the services. The reports provide one of the broadest
    examinations to date of prevention health care quality for the nation and
    among key priority populations, measuring quality of care across a range of
    dimensions, including the degree to which care is safe, patient centered,
    timely, and effectively delivered. They track more than 50 primary and
    secondary prevention quality-of-care measures in five clinical areas,
    including cancer, diabetes, heart disease, maternal and child health, and
    respiratory disease.

Findings of the NHQR and NHDR
Table 1 summarizes the major conclusions of the two reports: the promise
    of high-quality health care is not a given, gaps in quality are particularly
    acute for certain racial, ethnic, and socioeconomic groups, and improvement
    is possible. 
NHQR findings
    In general, progress has been mixed at best in preventive care service 
    quality. For example, performance has deteriorated or not improved for three 
    quarters of the 21 prevention quality measures in which trend data are available.
    Similarly, the reports track a set of measures assessing the rate of
    hospital admissions for conditions that often can be managed in an
    ambulatory care setting with proper primary and secondary preventive care.
    Seven of the 10 preventable hospitalization measures with trend data have
    either not improved or deteriorated. In addition, while hospital discharge 
    rates declined from 1997 to 2000 for uncontrolled
    diabetes (by 30%) and for pediatric gastroenteritis (by 16%),
    pediatric asthma discharge rates did not change in a statistically
    significant way (18). 
    In some areas, however, prevention health care quality has improved. For
    example, the incidence rate of new cases of cervical and colorectal cancers
    detected at an advanced stage has been declining for decades. The percentage of institutionalized
    adults (persons in long-term care or nursing homes) who have ever received
    pneumococcal vaccination, while still low at 33% (1999), has improved from
    25% (1997). More than 73% of children aged 19 to 35 months have all their
    recommended vaccinations. And 83% of women obtain prenatal care in their
    first trimester. 
NHDR findings
    Significant differences exist in the use of evidence-based preventive
    services for certain populations, particularly people of lower socioeconomic
    status (SES) and some minorities. For example:
    
- People of lower SES and some minorities are less likely to have
        colorectal and breast cancer screening.
 
- People of lower SES and Hispanics are less likely to have blood
        pressure and cholesterol screening in addition to counseling and treatment
        for some cardiac risk factors.
      
 - People of lower SES and blacks are less likely to have recommended
        childhood immunizations before the age of four years.
      
 - Children of lower SES and some minority children are less likely to
        have dental care.
      
 - Lower-SES, black, and Hispanic adults are less likely to have
        recommended immunizations for influenza and pneumococcal disease.
 
 
Preventive care for specific diseases
    NHQR and NHDR findings for cancer, diabetes, and heart disease are
    presented below. 
Cancer Cancer screening allows for the detection of precancerous
    abnormalities and the early detection of disease and, when followed by
    appropriate treatment, can lead to a reduction in the likelihood of illness
    and death. The reports track performance in cancer screening for breast,
    colorectal, and cervical cancer (Figure). A majority of women 40 and older (70%) is screened with mammography  for breast cancer, which
    already meets the Healthy People 2010 objective, although this
    clearly does not approach the theoretical limit of 100%. The rate of screening for
    colorectal cancer (33% for fecal occult blood testing and 39% for flexible 
    sigmoidoscopy) is less than half that for cervical cancer
    screening (81%) and has a long way to go to meet the Healthy People 2010
    goal of 50%.

    National Healthcare Quality Report. Data not available for colorectal 
    screening rates for 1999. Data from National Health Interview
    Survey, 2000 (19). 
Diabetes High quality of care for diabetes requires that
    people with diabetes receive the tests, exams, and treatments that can help
    them and their providers manage their condition.  Table 2 shows variability
    in the rate of delivery of services across the five process measures of
    care, ranging from a low of 54.8% for influenza immunization to a high of
    94.3% for a lipid profile test.  Of particular note is that only 23% of
    people with diabetes get all recommended secondary preventive services. 
Heart disease The reports track performance in screening for high
    blood pressure and high cholesterol and in delivering smoking cessation
    counseling. 
Blood pressure screening. Ninety percent of Americans reported having 
    their blood pressure checked in the past two years. According to 1998 data 
    from the Centers for Disease Control and Prevention’s National
        Health Interview Survey (NHIS), women (93%) and older adults (92%) are
        more likely to be checked; Hispanics are screened at lower rates (84%)
        (21).
      Cholesterol screening. Cholesterol screening rates have
        increased in the last two decades. According to 1998 NHIS data, 67% of
        adults had their cholesterol checked within the previous five years and
        more than 80% of adults aged 45 or older had their cholesterol checked
        (21).  
Counseling smokers to quit. In 2000, 62% of smokers who had a
        routine office visit reported that their doctors had advised them to
        quit. According to 2000 NHIS data, individuals who report poor to fair
        health are more likely to be counseled to quit (75%) than those who
        report good to excellent health (58%) (19). Furthermore, less than half (42%) of
        acute myocardial infarction (AMI) patients who smoke are counseled to
        quit while in the hospital. AMI patients who are counseled to quit
        smoking while in the hospital are more likely than those counseled in
        other settings to be abstinent from smoking a year later (20).

Conclusions and 
    Implications
The NHQR and NHDR are two of the most comprehensive national assessments
    of preventive care quality in the United States. They show that the U.S.
    health care system is missing numerous opportunities to provide
    evidence-based preventive care and that usage rates for a number of
    preventive care services are not improving. Significant progress is needed
    in areas such as colorectal cancer screening, delivery of the full
    complement of diabetes secondary preventive services, and cessation
    counseling for smokers, particularly when they are admitted to the hospital
    for heart attacks. 
The purpose of the reports, according to the Congressional mandate that
    created them, is to document the state of health care quality for the
    nation. The reports do not address the determinants of health care quality,
    nor do they prescribe how quality of care could be improved or suggest a
    national agenda for improving quality. Many public and private entities
    address these important research, policy, and quality-improvement questions. 
The reports contribute to the quality-improvement cycle by providing
    national information on the state of health care quality, potential
    benchmarks, and changes that have occurred over time to support a broad
    community of concerned quality-improvement professionals. Information is
    critical to helping this broad community  understand how gaps and
    opportunities apply to their own local needs and  facilitate their move
    from data to action. The reports offer more than 525 tables that provide
    essential information for researchers to analyze the important questions
    about why performance is the way it is. The reports can help policy makers
    formulate an agenda for quality by creating understanding about the greatest
    needs among a wide variety of concerns. Similarly, the reports can serve as
    a scorecard on the collective performance of all those involved in quality
    improvement. 
In addition to tracking health care quality through the reports, the AHRQ
    supports quality improvement for the nation by conducting research to
    determine evidence-based prevention practices, translating research into
    knowledge, and facilitating the use of knowledge toward the goal of
    improving the quality of prevention services for all Americans.

    Quality Report and National Healthcare Disparities Report, Agency for
    Healthcare Research and Quality, 2003
High-quality health care is not a given in
the U.S. health care system.
- Thirty-seven of 57 areas with trend data
presented in the NHQR have either shown no improvement or have
deteriorated.
 
- Only 23% of individuals with hypertension have
it under control. Control of hypertension is essential to
continued successes in reducing mortality from heart disease,
stroke, and complications of diabetes.
 
- Half of the people with depression stop using
their medicines within the first month, far shorter than is
recommended by experts and scientific evidence.
 
- In terms of patient safety, about one in five
elderly Americans was prescribed medications that may have been
inappropriate for them and potentially harmful.
 
  | 
 
Gaps in health care quality are particularly
acute for certain racial, ethnic, and socioeconomic
groups.
- Blacks and Hispanics experience worse quality
of care for about half of the quality measures reported in the
NHQR and NHDR.
 
- Hispanics and Asians experience worse access to
care for about two thirds of access measures.
 
- Poor people experience worse care for about two
thirds of the quality and access measures.
 
  | 
 
Improvement in quality and disparities is
possible.
- Chosen as a national priority for improvement
by the Medicare QIO program, the use of beta blockers for heart
attack patients rose from 21% of eligible patients in the early
1990s (16) to 79%a. In addition, improvement on this
measure has been relatively universal. Fully 45 states are at or
above 70% on this measure.
 
- A majority of women older than 40 years (70.3%) is being screened by mammography for breast cancer, exceeding
the Healthy People 2010 objective.
 
- Black women have higher screening rates for
cervical cancer, perhaps related to significant investments in
community-based cancer screening and outreach programs for
cervical cancer. This data may help explain why death rates among
black women, although still more than twice those of white women, have
been decreasing at about twice the rate (17).
 
- Quality improvement efforts have resulted in
demonstrable reductions in black/white differences in hemodialysis. A targeted intervention within a quality
improvement culture may offer important lessons in disparity
reduction.
