Agreement of medication information derived from EHR data compared to Medicare insurance claims: an analysis of biologic disease-modifying antirheumatic drugs.
This study compared the agreement between medication information derived from ambulatory electronic health record (EHR) data to medication information from administrative claims for high-cost specialty drugs for rheumatoid arthritis (RA). The authors used data from a national EHR-enabled registry, the Rheumatology Informatics System for Effectiveness (RISE), with linked Medicare claims in a population of patients with rheumatoid arthritis (RA) to investigate variations in agreement for different biologic disease-modifying agents (bDMARDs) between two data sources (RISE EHR data vs. Medicare claims), categorized by drug, route of administration, and patient insurance factors (dual eligibility for Medicare and Medicaid). They reviewed data for patients ≥ 65 years old, with ≥ 2 visits in RISE with RA ICD codes ≥ 30 days apart, and continuous enrollment in Medicare Parts B and D in 2017-2018. They found that EHR data had a sensitivity of 75.0-90.8% for identifying patients with the same medication and route. Positive predictive value (PPV) for Part B bDMARDs was higher compared with Part D bDMARDs. They observed higher PPVs for Part D bDMARDs among patients who were dual-eligible.

Measuring patient safety: the Medicare Patient Safety Monitoring System (past, present, and future).
This review article discusses the development, strengths and limitations, and future of the Medicare Patient Safety Monitoring System (MPSMS), which was created more than 10 years ago. MPSMS is a chart review-based national patient safety surveillance system that provides rates of 21 specific hospital inpatient adverse event measures, which are divided into 4 clinical domains (general, hospital-acquired infections, post-procedure adverse events, and adverse drug events). The 2014 MPSMS national sample was drawn from 1109 hospitals and includes approximately 20,000 medical records of patients admitted to the hospital for at least 1 of 4 conditions: congestive heart failure, acute myocardial infarction, pneumonia, and major surgical procedures as defined by the Centers for Medicare and Medicaid Services Surgical Care Improvement Project. The MSPMS is now undergoing a major transformation to capture additional types of adverse events, and is being renamed the Quality and Safety Review System (QSRS). Data will be electronically imported and will be updated and evolved over time to incorporate expanded standardized data available from electronic health records.

Horizontal and vertical integration's role in meaningful use attestation over time.
This study examined rates of attestation and attrition from the meaningful use (MU) program by independent, horizontally integrated, and vertically integrated physicians. The goal was to determine if MU created pressure for independent physicians to join integrated organizations. They compared attestation rates using secondary data from SK&A and Medicare MU Files from 2011-2016 with office-based physicians. The sample size was 291,234 physicians. Forty-nine percent of physicians that remained independent during the period attested to MU at least once during the program, compared with 70% that remained horizontally or vertically integrated. There was also significantly more attrition among independent physicians than those physicians who were integrated.

Improving medical record retrieval for validation studies in Medicare data.
The purpose of the study is to describe medical record retrieval for a study validating claims-based algorithms used to identify seven adverse events of special interest (AESI) in a Medicare population. It concluded that the national medical record validation study of claims-based algorithms produced a modest retrieval rate. The medical record procedures outlined in this paper could have led to the improved retrieval from the researchers’ previous medical record retrieval study.
