Iron parameters have not been well characterized in pre-dialysis patients with chronic kidney disease (CKD), and it remains unclear if abnormal iron balance is associated with increased mortality. Therefore, we performed a historical cohort study using data from the Veterans Affairs Corporate Data Warehouse to evaluate the relationship between iron status and mortality. We identified a pre-dialysis CKD cohort with at least one set of iron indices between 2006-2015.

Methods: Hospitalizations in Veterans with ESRD and evidence of dialysis between 01/01/2008 and 12/31/2013 were screened for TRAs using a clinical algorithm (CA) and four variations of claims-based algorithms (CBA 1-4). Criteria were implemented to exclude patients with non-ESRD-related anemia (e.
Recent evidence suggests almost half of repeat esophagogastroduodenoscopy procedures (EGDs) are overused; this prior research relied on administrative data that are often inaccurate. Our primary objective was to determine and compare the accuracy of natural language processing and administrative data to manual chart review to identify dysphagia indications for EGD procedures within the national VA healthcare system. From 396,856 EGD notes identified from 2008-2014, we classified 119,920 as "index" procedures in 2010-2012.

Objective: Identifying drug discontinuation (DDC) events and understanding their reasons are important for medication management and drug safety surveillance. Structured data resources are often incomplete and lack reason information. In this article, we assessed the ability of natural language processing (NLP) systems to unlock DDC information from clinical narratives automatically.

However, few resources exist that use real-time information on patient risk to prioritize coordinating appropriate care amongst a complex aging population.
Objective: To develop and validate a model to predict psychiatric hospital admission, during a 90-day risk window, in Veterans ages 65 or older with a history of mental health disease.
