Health system affiliation of physician organizations and quality of care for Medicare beneficiaries who have high needs.
The goal of this study was to test the hypothesis that health systems provide better care to patients with high needs compared to nonaffiliated physician organizations (POs). The 2015 Medicare Data on Provider Practice and Specialty linked physicians’ database was linked to POs Medicare Provider Enrollment, Chain, and Ownership System (PECOS) and IRS Form 990 data to identify health system affiliations. Among 2,323,301 beneficiaries with high needs, 52.3% received care from system-affiliated practices. The emergency department (ED) visit rate was statistically significantly different in system-affiliated POs and nonaffiliated POs. There were small differences for the remaining five of six quality measures examined: continuity of care, follow-up visits, all-cause readmissions, and ambulatory care-sensitive hospitalizations. Within systems there was substantial variation for rates of continuity of care and follow-up after ED visits.

Weighing the effects of vertical integration versus market concentration on hospital quality.
Provider organizations are increasing in complexity, as hospitals acquire physician practices and physician organizations grow in size. At the same time, hospitals are merging with each other to improve bargaining power with insurers. In this study, the investigators analyzed 29 quality measures reported to the Center for Medicare and Medicaid Services' Hospital Compare database for 2008 to 2015 to test whether vertical integration between hospitals and physicians or increases in hospital market concentration influenced patient outcomes.

Distinguishing high-performing health systems using a composite of publicly reported measures of ambulatory care.
The purpose of this study was to develop and evaluate a measure that ranks health care systems by ambulatory care quality. The authors concluded that their measure, using publicly reported data to produce valid, reliable, and stable ranks of ambulatory care quality for health care systems in Minnesota and California, could also be used in other applications.

Developing criteria and associated instructions for consistent and useful quality improvement study data extraction for health systems.
This paper describes AHRQ’s efforts to collate and assess quality improvement studies to support learning health systems (LHS). The authors identified quality improvement studies and evaluated the consistency of data extraction from two experienced independent reviewers at three time points: baseline, first revision, and final revision. Six investigators looked at the data extracted by the independent reviewers and determined the extent of similarity on a scale of 0 to 10. Two LHS participants were then asked to assess the relative value of their criteria. The consistency of extraction improved from a mean 1.17 score at baseline to 6.07 at first revision, and 6.81 at the final revision. There was not a significant improvement from the first to final revision. However, the LHS participants rated the value of these ratings a 9 and a 6, demonstrating that there is value in developing criteria.

Can vertically integrated health systems provide greater value: the case of hospitals under the comprehensive care for joint replacement model?
The authors sought to assess whether system providers perform better than non-system providers under an alternative payment model that incentivizes high-quality, cost-efficient care. Using CMS data linked to AHRQ’s Compendium of US Health Systems, along with secondary sources, they found that when operating under alternative payment model incentives, vertical integration may enable hospitals to lower costs with similar quality scores.

Financial integration's impact on care delivery and payment reforms: a survey of hospitals and physician practices. Health Aff 2020 Aug;39(8):1302-11. doi: 10.1377/hlthaff.2019.01813.
This study looked at whether financial integration of hospitals and physician practices was associated with greater quality. A total of 739 hospitals and 2,189 physician practices were included in the nationally representative survey. They were stratified by whether they were independent or owned by complex systems, simple systems, or medical groups. Nine scales were used to measure the level of adoption of diverse, quality-focused care delivery and payment reforms. While quality scores favored financially integrated systems for 4 of 9 hospital measures and one of 9 practice measures, none of them favored complex systems. Better quality was generally not associated with greater financial integration.

The quality of surgical care at hospitals associated with America's highest-rated medical centers.
The objective of this study was to assess whether the quality of surgical care changes as hospitals form networks with established, high-quality medical centers. The investigators concluded that network formation was not associated with a significant improvement in quality or reduction in Medicare expenditures across all procedures studied for hospitals joining the networks of America’s highest rated medical centers.
