Use of electronic health record (EHR) content for comparative effectiveness research (CER) and population health management requires significant data configuration. A retrospective cohort study was conducted using patients with diabetes followed longitudinally (N=36,353) in the EHR deployed at outpatient practice networks of 2 health care systems. A data(More)
OBJECTIVES We used a U.S. model of health care costs to examine the cost effectiveness of enoxaparin compared with unfractionated heparin (UFH) as adjunctive therapy for fibrinolysis in patients with ST-segment elevation myocardial infarction (STEMI). BACKGROUND The ExTRACT-TIMI 25 (Enoxaparin and Thrombolysis Reperfusion for Acute Myocardial Infarction(More)
BACKGROUND Diabetes is a leading cause of death and disability, and its prevalence is increasing. When diet fails, patients with type 2 diabetes mellitus (T2DM) are prescribed oral hypoglycemics for glycemic control. Few studies have explored initial use or change from initial oral hypoglycemic therapy in the primary care setting. We aimed to describe the(More)
An intermediate care decision tree tool was developed to meet the demand for intermediate care beds. Concurrently, a charging process was developed to support the acuity adaptable model of care, allowing the patient to remain in the same bed from admission to discharge, regardless of level of care required, adjusting nurse-to-patient ratios as acuity(More)
BACKGROUND The economic impact of bleeding in the setting of nonemergent percutaneous coronary intervention (PCI) is poorly understood and complicated by the variety of bleeding definitions currently employed. This retrospective analysis examines and contrasts the in-hospital cost of bleeding associated with this procedure using six bleeding definitions(More)
OBJECTIVE To determine whether or not implementation of an electronic medical record (EMR) in a primary care office is associated with an increase in completion of preventive care for a general population of adults and children, and for adults with diabetes mellitus. DESIGN Observational cohort study that compared the change in completion rate of(More)
BACKGROUND Patients with untreated substance use disorders (SUDs) are at risk for frequent emergency department visits and repeated hospitalizations. Project Engage, a US pilot program at Wilmington Hospital in Delaware, was conducted to facilitate entry of these patients to SUD treatment after discharge. Patients identified as having hazardous or harmful(More)
BACKGROUND Warfarin is recommended for stroke prevention in high-risk patients with atrial fibrillation. However, it is often underutilized and inadequately managed in actual clinical practice. OBJECTIVES To examine the patterns of warfarin use and their relationship with stroke and bleeding in atrial fibrillation patients in community-based primary care(More)
Star schema, which maintains one-to-many relationships between dimensions and a fact table, is widely accepted as the most viable data representation for dimensional analysis. Real-world DW schema, however, frequently includes many-to-many relationships between a dimension and a fact table. Having those relationships in a dimensional model causes several(More)
1. ABSTRACT Healthcare presents unique challenges for the architect of a data warehouse. Integrated health systems are shifting its focus away from the acute care setting and moving towards cross-continuum care management. Improving healthcare quality while reducing costs requires the elimination of unnecessary variation in the care process. This paper(More)
