´óÏóAPP

The Consumer Assessment of Healthcare Providers and Systems (CAHPS®) program is a multi-year initiative of the ´óÏóAPP (AHRQ) to develop surveys of patients' experiences with the healthcare they receive from health plans, providers, and facilities such as hospitals, in-center hemodialysis facilities, and home health agencies. The CAHPS program also houses a database for voluntarily submitted survey data from health plans and group practices to support; research quality improvement. Many CAHPS surveys are mandated by the Centers for Medicare and Medicaid Services for public reporting and in pay-for-performance initiatives.

CAHPS® surveys are designed to capture patients' reports and ratings of their experiences with health care services. Specifically, the surveys probe domains that meet the following criteria:

• Consumers and patients are the best and/or only source of information. CAHPS® surveys do not attempt to collect information that can be gathered more effectively through other means (e.g., through medical records or from physicians).
• Consumers and patients have identified the survey domains as being important. The CAHPS® program devotes substantial resources to identifying and confirming the issues that are salient to consumers and influence their decisions, and that the survey questions are meaningful and comprehensible to consumers.

Examples of domains covered by CAHPS® surveys include getting timely appointments, care and information; how well providers communicate with patients; providers' use of information to coordinate care; helpful, courteous and respectful office staff, and customer service.

The CAHPS® surveys were developed with scientific rigor. ´óÏóAPPmakes sure the surveys are up to date and that the surveys are consistent with the best practices and that they produce useful information. CAHPS surveys are designed to capture information about the experience of care, rather than patient satisfaction. Because of the emphasis on patient experience, CAHPS surveys offer information that's concrete and actionable. One of the most concrete benefits of CAHPS surveys is being able to compare one health care organization's performance to similar organizations.

The CAHPS® Database is the national repository for data from the CAHPS family of surveys. Since its inception in 1998, this database has served as an important resource for survey sponsors, researchers, and others interested in using comparative CAHPS survey results and detailed benchmark data. The CAHPS Database contains respondent-level survey data, characteristics of entities surveyed (e.g., health plans, medical groups and practice sites), and other information related to survey administration. These data and information are submitted voluntarily by survey users according to standard specifications.

The CAHPS® Ambulatory Care Improvement Guide is a comprehensive resource for health plans, medical groups, and other providers seeking to improve their performance in the domains of patient experience measured by CAHPS surveys of ambulatory care. This guide will help organizations: cultivate an environment that encourages and sustains improvements in patient-centered care; analyze the results of CAHPS surveys and other forms of patient feedback to identify strengths and weaknesses; and develop strategies for improving performance. The Guide helps organizations assess their readiness to improve, assess ways to approach the quality improvement process, determine where to focus efforts, and help to develop strategies for improving patient experience in ambulatory care settings.

The Medical Expenditure Panel Survey (MEPS) is a nationwide study conducted to learn more about the health care services people use, the charges for those services, and how those services are paid for. MEPS is conducted annually by the U.S. Department of Health and Human Services (DHHS) through the ´óÏóAPP (AHRQ) and the Centers for Disease Control and Prevention (CDC). Major components of MEPS include surveys of:

• A nationally representative sample of households.
• Hospitals, physicians, and other medical providers including pharmacies reported by the household participants.
• Providers of health insurance.

MEPS is the most complete source of data available on health care use and expenses in the United States. For more detailed information on MEPS, go to: .

The software packages most suitable for analyzing Medical Expenditure Panel Survey (MEPS) data are SAS, Stata, SPSS, SUDAAN, and R survey. For more information, go to .

The ´óÏóAPPData Center is a place where researchers with approved projects can access MEPS files that are not available for public use. These files may contain data that ´óÏóAPPhas not fully edited, or may contain levels of detail that are not approved for public release.

Within the documentation for the MEPS-HC public use data files a variable-source crosswalk is provided. The following information is provided: variable; description; and source.

Data files and their accompanying documentation can be found at .

For reasons of confidentiality, the MPC file cannot be publicly released. The MPC is not designed to produce national estimates, and, for budgetary reasons, not all household-reported events are fielded in the MPC. MPC data are used to supplement/replace household data to produce the MEPS expenditure estimates. Selected data elements from the MPC data collection may be accessed in the or one of the for approved research projects.
