Performance in the Medicare Shared Savings Program after accounting for nonrandom exit: an instrumental variable analysis.
The purpose of this study was to evaluate the effect of the Medicare Shared Savings Program (MSSP) on spending and quality while accounting for clinicians' nonrandom exit. MSSP ACO participants were compared with control beneficiaries using adjusted longitudinal models that accounted for secular trends, market factors, and beneficiary characteristics. Results showed that, after adjustment for clinicians' nonrandom exit, the MSSP was not associated with improvements in spending or quality. Selection effects, including exit of high-cost clinicians, may drive estimates of savings in the MSSP.

Mind the gap: observation windows to define periods of event ascertainment as a quality control method for longitudinal electronic health record data.
Under the hypothesis that use of electronic health records in health research may lead to false assumptions of complete event ascertainment, the authors of this article estimated "observation windows" (OWs) as a quality-control approach to reduce the likelihood of false assumption. The impact of OWs on estimating rates of type II diabetes mellitus from HIV clinical cohorts are demonstrated. Data from 16 HIV clinical cohorts to the NA-ACCORD were used to identify and evaluate OWs for an operationalized definition of diabetes occurrence. The authors conclude that OWs have utility as a quality-control approach to complete event ascertainment and help to improve the accuracy of estimates.

Using clinical vignettes to assess quality of care for acute respiratory infections.
Overprescribing of antibiotics for acute respiratory infections (ARIs) is common. The objective of this study was to develop and validate a vignette-based method to estimate clinician ARI antibiotic prescribing. The researchers concluded that responses to 3 clinical vignettes can identify clinicians with relatively poor quality ARI antibiotic prescribing. Vignettes may be a mechanism to target clinicians for quality improvement efforts.

AHRQ's role in improving quality, safety, and health system performance.
The author, director of AHRQ, focuses on several topics including investing in research and evidence to understand how to improve the safety and quality of health care, and generating measures and data used to track and improve performance and evaluate progress of the U.S. health-care system. He concludes by discussing AHRQ’s continuing exploration of ways to expand its efforts in patient safety into nonhospital settings.
