Contents

Consumer Assessment of Healthcare Providers and Systems is a standardized family of patient experience surveys designed to measure healthcare users' reports of care across multiple settings. It informs comparative performance reporting, payment models, accreditation, and quality improvement programs used by Centers for Medicare and Medicaid Services, Agency for Healthcare Research and Quality, National Committee for Quality Assurance, Joint Commission on Accreditation of Healthcare Organizations, and private payers. The program interfaces with national measurement initiatives involving U.S. Department of Health and Human Services, Patient-Centered Outcomes Research Institute, Institute of Medicine, Robert Wood Johnson Foundation, and state health agencies.

Overview

CAHPS was created to provide publicly comparable data on patient experience for consumers, purchasers, and policymakers. Major stakeholders include Centers for Medicare and Medicaid Services, Agency for Healthcare Research and Quality, American Medical Association, American Hospital Association, Kaiser Permanente, and health plans such as UnitedHealth Group and Aetna. The surveys operate alongside reporting frameworks from National Committee for Quality Assurance and accreditation standards from the Joint Commission on Accreditation of Healthcare Organizations to inform pay-for-performance initiatives tied to programs like Medicare Advantage and Medicaid managed care. CAHPS outcomes are used in national reporting platforms associated with Hospital Compare, Physician Compare, and state-based quality collaboratives coordinated by entities including the Commonwealth Fund and Massachusetts Health Quality Partners.

The methodological development was led by teams at the Agency for Healthcare Research and Quality, with psychometric consultation from researchers at RAND Corporation, Harvard School of Public Health, Johns Hopkins University, and Yale School of Medicine. Early field testing drew on survey methods literature from University of Michigan, NORC at the University of Chicago, and University of California, Los Angeles. Instrument construction followed principles promulgated by panels convened by the Institute of Medicine and incorporated standards articulated by the U.S. Office of Management and Budget for survey design. Sampling frameworks reference stratified and cluster designs used in studies by Centers for Disease Control and Prevention and methodology from National Center for Health Statistics to support representativeness across Medicare, Medicaid, and commercial enrollee populations.

CAHPS includes multiple instrument variants tailored to settings and populations: the Clinician and Group CAHPS used in initiatives by American Academy of Family Physicians and American College of Physicians; the Hospital CAHPS used in Hospital Consumer Assessment of Healthcare Providers and Systems reporting linked to Centers for Medicare and Medicaid Services reimbursement; the Home Health CAHPS relevant to providers regulated by Centers for Medicare and Medicaid Services and state survey agencies; and the Health Plan CAHPS employed by insurers including Blue Cross Blue Shield Association and Humana. Other specialized modules reference measurement work at RAND Corporation, University of Minnesota, and University of Pittsburgh to evaluate behavioral health, maternity care, and pediatric experiences. The program incorporates modular item sets that align with standards from the National Quality Forum and reporting requirements for programs such as Accountable Care Organization contracts.

Healthcare systems deploy CAHPS for public reporting, internal quality improvement, and contractual performance measurement with purchasers like Centers for Medicare and Medicaid Services and large employers represented by groups such as the Business Roundtable and National Business Group on Health. Hospitals integrate Hospital CAHPS data into dashboards alongside metrics from Society of Hospital Medicine and American Hospital Association initiatives. Large integrated delivery systems such as Veterans Health Administration, Mayo Clinic, and Cleveland Clinic use CAHPS-derived measures to guide service redesign and patient experience programs modeled on frameworks by Beryl Institute and Institute for Healthcare Improvement. State Medicaid programs leverage CAHPS data for managed care oversight in jurisdictions like California Department of Health Care Services and New York State Department of Health.

Psychometric evaluation has been conducted by investigators at RAND Corporation, Harvard Medical School, University of Washington, and Dartmouth College, assessing reliability, validity, and case-mix adjustment. Studies compare CAHPS composites to clinical quality measures endorsed by the National Quality Forum and to outcomes research performed through collaborations with Patient-Centered Outcomes Research Institute. Reliability analyses report Cronbach's alpha and intraclass correlation coefficients using methods established at University of Chicago and Princeton University; validity testing includes convergent and discriminant approaches referenced in work by Columbia University and Stanford University. Case-mix adjustment protocols follow guidance from Agency for Healthcare Research and Quality and analytic methods taught at Carnegie Mellon University and University of Pennsylvania.

CAHPS data have influenced policy decisions in programs administered by Centers for Medicare and Medicaid Services and informed accreditation processes used by the Joint Commission on Accreditation of Healthcare Organizations. Pay-for-performance and value-based purchasing initiatives from Centers for Medicare and Medicaid Services incorporate CAHPS measures alongside clinical metrics used in Merit-based Incentive Payment System and Hospital Value-Based Purchasing Program. Research funded by the Robert Wood Johnson Foundation, Kaiser Family Foundation, and Commonwealth Fund shows associations between CAHPS scores and hospital readmissions, patient adherence, and service utilization patterns studied at Yale School of Medicine and Duke University Medical Center. CAHPS continues to be a component of national measurement strategies coordinated with entities such as the Office of the National Coordinator for Health Information Technology and international benchmarking undertaken by organisations like Organisation for Economic Co-operation and Development.
