<h3>2010 National Healthcare Quality and Disparities Reports</h3>
<div class="page-description"><span>The National Healthcare Quality Report (NHQR) is a comprehensive national overview of quality of health care in the United States. It is organized around four dimensions of quality of care: effectiveness, patient safety, timeliness, and patient centeredness.</span></div>

<br /><h2>HIV Research Network (HIVRN)</h2><h3>Sponsors</h3><p>U.S. Department of Health and Human Services: Agency for Healthcare Research and Quality (AHRQ); and Health Resources and Services Administration (HRSA), HIV/AIDS Bureau (HAB).</p><h3>Description</h3><p>The HIVRN currently includes 17 medical practices across the United States that collectively treat more than 14,000 patients. Each practice collects information on clinical and demographic characteristics of their patients with HIV infection, prescribed medications, frequency of outpatient clinic visits, and number of inpatient admissions. Each practice sends information to the data coordinating center at the Johns Hopkins School of Medicine, which consolidates this information into a single uniform database.</p><h3>Population Targeted</h3><p>Data from patients seen at one of the HIVRN medical practices.</p><h3>Years Collected</h3><p>Since 2000.</p><h3>Schedule</h3><p>Annual.</p><h3>Geographic Estimates</h3><p>Although the data collection sites are located in every region of the country, data are not representative and regional projections cannot be made from HIVRN data.</p><h3>Contact Information</h3><p>Organization home page: <a href="https://www.ahrq.gov/index.html">http://www.ahrq.gov</a>.</p><h3>Reference</h3><p>HIV Research Network. Hospital and outpatient health services utilization among HIV-infected patients in care in 1999. <em>J Acquir Immune Defic Syndr</em> 2002;30:21-26.</p><hr /><h2>Medical Expenditure Panel Survey (MEPS)</h2><h3>Sponsor</h3><p>U.S. Department of Health and Human Services, Agency for Healthcare Research and Quality (AHRQ); and Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).</p><h3>Mode of Administration</h3><p>The MEPS Household Component (HC), the core survey, is an interviewer-administered computer-assisted personal interview household survey. The Self-Administered Questionnaire and Diabetes Care Survey are supplementary self-administered paper questionnaires.</p><h3>Survey Sample Design</h3><p>The sampling frame for the MEPS-HC is drawn from respondents to the National Health Interview Survey (NHIS), conducted by NCHS. The MEPS-HC augments NHIS by selecting a sample of NHIS respondents, collecting additional data on their health care expenditures, and linking these data with additional information from the respondents&#39; medical providers, employers, and insurance providers.</p><p>Each year a new panel of households is selected from among those households that participated in the previous year&#39;s NHIS. Data covering 2 calendar years of information are collected for each new annual sample (referred to as a panel), through a series of five rounds of data collection over a 2&amp;frac12;-year period. This series of data collection activities is repeated each year on a new sample of households, resulting in overlapping panels of survey data. MEPS annual data are based on information from two separate panels, the panel that began that year and the panel that began in the previous year.</p><p>The NHIS provides a nationally representative sample of the U.S. civilian noninstitutionalized population, with oversampling of Hispanics and Blacks. Starting in 2006, the NHIS oversamples Asians as well. In addition to the oversampling by NHIS, MEPS oversamples policy-relevant groups such as low-income households.</p><h3>Primary Survey Content</h3><p>MEPS includes three component surveys: the Household Component (HC), the Medical Provider Component, and the Insurance Component. The MEPS-HC collects detailed data on demographic characteristics, health conditions, health status, use of medical care services, charges and payments, access to care, satisfaction with care, health insurance coverage, income, and employment. The data for the NHQR and NHDR are primarily from the following sections of the 2002-2007 MEPS-HC:</p><ul><li>Self-Administered Questionnaire (SAQ): This self-administered paper questionnaire collects a variety of adult health and health care quality measures.</li><li>Diabetes Care Survey: This self-administered paper questionnaire, given to persons identified as ever having had diabetes, asks about their diabetes care, such as services rendered.</li><li>Child Health and Preventive Care (CHPR) section: Starting in 2001, the CHPR section was added to the MEPS-HC interviews during the second half of the year. It included health care quality measures taken from the health plan version of CAHPS&#174; (Consumer Assessment of Healthcare Providers and Systems); the Children With Special Health Care Needs screener questions; children&#39;s general health status as measured by several questions from the General Health Subscale of the Child Health Questionnaire; Columbia Impairment Scale questions about possible child behavioral problems; and child preventive care questions. Before 2001, the CAHPS&#174; questions and the Children With Special Health Care Needs screener questions had been in the Parent-Administered Questionnaire (PAQ). Therefore, estimates from 2001 may not be comparable with estimates for 2000 or earlier years.</li><li>Access to Care: The Access to Care section of the MEPS-HC gathers information on five main topic areas: family members&#39; origins and preferred languages; family members&#39; usual source of health care; characteristics of usual source of health care providers; satisfaction with and access to the usual source of health care provider; and access to medical treatment, dental treatment, and prescription medicines.</li><li>Preventive Care: For each person, a series of questions was asked primarily about the receipt of preventive care or screening examinations.</li></ul><h3>Population Targeted</h3><p>Like the NHIS population from which its sample is drawn, the MEPS-HC is a nationally representative survey of the U.S. civilian noninstitutionalized population.</p><h3>Demographic Data</h3><p>The MEPS-HC collects data on demographic characteristics, including age, gender, race, ethnicity, education, industry and occupation, employment status, household composition, and family income. Race and ethnicity variables and categories changed in 2002 in compliance with Office of Management and Budget standards.</p><h3>Years Collected</h3><p>MEPS is the third in a series of national probability surveys conducted by AHRQ on the financing and use of medical care in the United States. The National Medical Care Expenditure Survey (NMCES) was conducted in 1977; the National Medical Expenditure Survey (NMES) in 1987; and the Medical Expenditure Panel Survey (MEPS), an annual survey, was conducted beginning in 1996.</p><h3>Schedule</h3><p>Annual.</p><h3>Geographic Estimates</h3><p>National; four U.S. Census Bureau regions (Northeast, Midwest, South, and West); selected States; metropolitan and nonmetropolitan areas; as well as urban-rural classification, such as the 2006 NCHS Urban-Rural Classification Scheme for Counties (<a href="http://www.cdc.gov/nchs/data_access/urban_rural.htm">http://www.cdc.gov/nchs/data_access/urban_rural.htm</a>).</p><h3>Notes</h3><p>Estimates in the NHQR and NHDR Data Tables appendix that are based on MEPS data are weighted to reflect the experiences of the U.S. civilian noninstitutionalized population. Standard errors of the estimates were derived using SUDAAN statistical software, which factors in MEPS complex survey design. MEPS estimates are suppressed when they are based on sample sizes below 100 or when their relative standard errors are 30 percent or more.</p><p>The combined response rate for MEPS, which includes the NHIS response rate, ranged from 57 percent to 65 percent during the 2002 to 2007 period.</p><h3>Contact Information</h3><p>Agency home page: <a href="https://www.ahrq.gov/index.html">http://www.ahrq.gov</a>.</p><p>Data system home page: <a href="http://meps.ahrq.gov/">http://meps.ahrq.gov</a>.</p><h3>References</h3><p>Ezzati-Rice TM, Rohde F, Greenblatt J.

The agencies are the Centers for Disease Control and Prevention (CDC), the Food and Drug Administration (FDA), the Office of the National Coordinator for Health Information Technology (ONC), the Veterans Health Administration (VHA), and the Department of Defense.</p><p>In addition to the FAWG, MPSMS depends on guidance from a multidisciplinary Technical Expert Panel of non-Federal experts for their knowledge and experience in the areas of patient safety and quality improvement.</p><h3>Description</h3><p>MPSMS is a nationwide surveillance system that aims to identify rates of specific adverse events or unintended patient harm, injury, or loss among hospitalized patients. The system tracks and monitors interactions with the health care system rather than health conditions.</p><p>MPSMS is composed of 21 measures. These represent six types of adverse drug events, five types of hospital-acquired infections, five types of adverse events associated with surgery, injuries and infections that can occur as a result of different types of catheterization, patient falls, and hospital-acquired pressure ulcers. MPSMS data are used to develop a summary patient safety event rate based on these 21 measures.</p><p>A sample of approximately 18,000 inpatient hospital records is randomly selected from the annual national CMS Reporting Hospital Quality Data for Annual Payment Update (RHQDAPU) program. Data are collected for hospital inpatients age 18 years and over who are covered by any insurance payer. All RHQDAPU records fall into four categories of interest: heart failure, acute myocardial infarction, pneumonia, and a subset of surgical procedures.<sup><a href="#_ftn1" id="_ftnref1" name="_ftnref1">i</a></sup> Records are sent to the Clinical Data Abstraction Center, where trained abstractors abstract each clinical chart by recording predefined questions and responses. Qualidigm uses algorithms to analyze the abstracted data to identify patient exposure to the processes of care, ascertain the occurrence of specific adverse events, and assess patient risk factors and outcomes.</p><h3>Primary Content</h3><p>The purpose of MPSMS is to provide a tool to facilitate improvements in patient safety by gaining an understanding of the magnitude of specific patient safety issues associated with the processes of hospital care delivery. Adverse event categories monitored by MPSMS include the following:</p><ul><li>Adverse events associated with the use of central venous catheters (CVCs).</li><li>Certain adverse events associated with major surgical procedures.</li><li>Adverse events specifically associated with joint revisions and replacements.</li><li>Hospital-acquired ventilator-associated pneumonia.</li><li>Certain hospital-acquired infections.</li><li>Adverse drug events that are associated with the hospital stay and not present on admission.</li><li>Hospital-acquired pressure ulcers.</li><li>In-hospital patient falls.</li></ul><p>MPSMS also collects and examines patient risk factors, such as demographics and presence of comorbid conditions. Outcomes, such as length of hospital stay and in-hospital mortality, are also collected.</p><h3>Population Targeted</h3><p>A sample of approximately 18,000 inpatient hospital records is randomly selected from the annual national CMS Reporting Hospital Quality Data for Annual Payment Update (RHQDAPU) program. Data are collected for hospital inpatients age 18 years and over who are covered by any insurance payer.
