This study used discharge data from five states to evaluate the impact of the Affordable Care Act’s Medicaid expansion on patient safety outcomes (measured using the PSI 90 composite). Results showed an overall improvement in patient safety in expansion states; however, when expansion states experienced an increase in their safety-net burden, they also experienced significantly more safety events compared to nonexpansion states.

The Team Checkup Tool stemmed from work done as part of the Keystone ICU project and is designed to identify barriers to the progress of quality improvement initiatives. In this study, investigators used focus groups and feedback sessions to assess the content of the tool. They conclude that the Team Checkup Tool measures meaningful aspects of team-based quality improvement work.
