Using a society database to evaluate a patient safety collaborative: the Cardiovascular Surgical Translational Study.
The authors assessed the utility of using external databases for quality improvement (QI) evaluations in the context of an innovative QI collaborative aimed to reduce three infections and improve patient safety across the cardiac surgery service line. They compared changes in each outcome between 15 intervention hospitals and 52 propensity score-matched hospitals, and found that improvement trends in several outcomes among the studied intervention hospitals were not statistically different from those in comparison hospitals. They conclude that using external databases may permit comparative effectiveness assessment by providing concurrent comparison groups, additional outcome measures, and longer follow-up.

Grading the strength of a body of evidence when assessing health care interventions: an EPC update.
The authors discussed the state of revision of 2010 guidance on grading the strength of evidence (SOE) of the effectiveness of drugs, devices, and other preventive and therapeutic interventions in systematic reviews produced by AHRQ's Evidence-based Practice Center (EPC) program. They concluded that EPC working groups will consider ongoing challenges and modify guidance as needed, on issues such as combining trials and observational studies in bodies of evidence, weighting domains, and combining qualitative and quantitative syntheses.
