Is bigger better?: A closer look at small health systems in the United States.
The purpose of this study was to expand existing health systems research by comparing the features, cost, and quality of care in small U.S. health care systems with those of large U.S. health systems. In this retrospective study with a repeated cross-sectional analysis, the researchers evaluated between 468 and 479 large health systems and between 608 and 641 small health systems serving fee-for-service Medicare beneficiaries, yearly between the year of 2013 and 2017. The study found that small systems had a larger share of beneficiaries and practice sites in small towns or rural areas, performance quality was lower in small systems that in large systems, and there was no difference in total cost of care. The study concluded that the quality of care in small systems is lower than large systems, but small systems provide care for rural Medicare populations. The researchers recommended that future research should explore the reasons for why these differences exist in quality.

ACOs holding commercial contracts are larger and more efficient than noncommercial ACOs.
The researchers examined differences between commercial accountable care organizations (ACOs) and noncommercial ACOs. They found that among all ACOs, there was low uptake of quality and efficiency activities; commercial ACOs reported more use of disease monitoring tools, patient satisfaction data, and quality improvement methods; and about two-thirds of the ACOs had established processes for distributing any savings accrued. They concluded that ACO delivery systems remain at a nascent stage.
