Impact of large scale, multicomponent intervention to reduce proton pump inhibitor overuse in integrated healthcare system: difference-in-difference study.

Objective: To determine how a large scale, multicomponent, pharmacy based intervention to reduce proton pump inhibitor (PPI) overuse affected prescribing patterns, healthcare utilization, and clinical outcomes.

Design: Difference-in-difference study.

Setting: US Veterans Affairs Healthcare System, in which one regional network implemented the overuse intervention and all 17 others served as controls.

Vibrational Spectroscopy as a Tool for Bioanalytical and Biomonitoring Studies.

The review briefly describes various types of infrared (IR) and Raman spectroscopy methods. At the beginning of the review, the basic concepts of biological methods of environmental monitoring, namely bioanalytical and biomonitoring methods, are briefly considered. The main part of the review describes the basic principles and concepts of vibration spectroscopy and microspectrophotometry, in particular IR spectroscopy, mid- and near-IR spectroscopy, IR microspectroscopy, Raman spectroscopy, resonance Raman spectroscopy, Surface-enhanced Raman spectroscopy, and Raman microscopy.

Effect of concomitant use of clopidogrel and proton pump inhibitors after percutaneous coronary intervention.

The aim of the present study was to analyze the effect of drug exposure patterns of clopidogrel and proton pump inhibitors (PPIs) on the clinical outcomes after percutaneous coronary intervention (PCI). Previous analyses predominantly included discharge medications and did not explore the effect of the drug exposure patterns. We analyzed all-cause death, nonfatal myocardial infarction, repeat revascularization, and major adverse cardiovascular events (MACE) in a cohort of 23,200 post-PCI patients (January 2003 to December 2008) using a multivariate adjusted Cox model and propensity-matched case-control analysis.
