DOI: https://doi.org/10.23970/ AHRQEPCERTA208.1. ii Preface The Agency for Healthcare Research and Quality (AHRQ), through its Evidence-based Practice Centers (EPCs), sponsors the development of evidence reports and technology assessments to assist public- and private-sector organizations in their efforts to improve the quality of health care in the United States. The reports and assessments provide organizations with comprehensive, science-based information on common, costly medical conditions, and new health care technologies and strategies. The EPCs systematically review the relevant scientific literature on topics assigned to them by AHRQ and conduct additional analyses when appropriate prior to developing their reports and assessments. In 2004, AHRQ launched a collection of evidence reports, Closing the Quality Gap: A Critical Analysis of Quality Improvement Strategies, to bring data to bear on quality improvement opportunities. These reports summarized the evidence on quality improvement strategies related to chronic conditions, practice areas, and cross-cutting priorities. This evidence report is part of a new series, Closing the Quality Gap: Revisiting the State of the Science. This series broadens the scope of settings, interventions, and clinical conditions, while continuing the focus on improving the quality of health care through critical assessment of relevant evidence. Targeting multiple audiences and uses, this series assembles evidence about strategies aimed at closing the “quality gap,” the difference between what is expected to work well for patients based on known evidence and what actually happens in day-to-day clinical practice across populations of patients. All readers of these reports may expect a deeper understanding of the nature and extent of selected high-priority quality gaps, as well as the systemic changes and scientific advances necessary to close them. AHRQ expects that the EPC evidence reports will inform consumers, health plans, other purchasers, providers, and policymakers, as well as the health care system as a whole, by providing important information to help improve health care quality.

The intent of bundled payment systems is to decrease health care spending while improving or maintaining the quality of care. Purpose. To systematically review studies of the effects of bundled payment on health care spending and quality, and to examine key design and contextual features of bundled payment programs and their association with program effectiveness. Data Sources. Electronic literature search of PubMed® and the Cochrane Library for studies published between 1985 and 2011. Study Selection. Title and abstract review followed by full-text review to identify studies that assessed the effect of bundled payment on health care spending and/or quality. Data Extraction. Two authors independently abstracted data on study design, intervention design, context, comparisons, and findings. Reviewers rated the strength of individual studies as well as the strength and applicability of the body of evidence overall. Differences between reviewers were reconciled by consensus. Studies were categorized by bundled payment program and narratively summarized. Data Synthesis. We reviewed 58 studies, excluding studies of the Medicare Inpatient Prospective Payment System, for which we reviewed
