The Guideline Interchange Format (GLIF) is a language for structured representation of guidelines. It was developed to facilitate sharing clinical guidelines. GLIF version 2 enabled modeling a guideline as a flowchart of structured steps, representing clinical actions and decisions. However, the attributes of structured constructs were defined as text(More)
While hyperglycemia is central to the pathogenesis and management of diabetes mellitus, hypoglycemia and glucose variability also contribute to outcomes. We previously reported on the relationship of glycemic control to outcomes in a large population of diabetic end-stage renal disease (ESRD) patients. Recognizing that ESRD is a risk factor for severe(More)
In order to enhance our understanding of how to best improve patient care, it was necessary to initially identify key questions that patients ask most frequently by recording actual calls made by home hemodialysis patients to a dialysis clinic over a three-month period. From an initial analysis of the recorded conversations, one of the most frequent reasons(More)
We evaluated external ventricular drain placement for factors associated with placement accuracy. Data were acquired using an electronic health record data requisition tool. Medical records of all patients who underwent ventriculostomy from 2003 to 2010 were identified and evaluated. Patient demographics, diagnosis, type of guidance and number of catheter(More)
Radiology reports are permanent legal documents that serve as official interpretation of imaging tests. Manual analysis of textual information contained in these reports requires significant time and effort. This study describes the development and initial evaluation of a toolkit that enables automated identification of relevant information from within(More)
INTRODUCTION Radiology reports communicate imaging findings to ordering physicians. The substantial information in these reports often causes physicians to focus on the summarized "impression" section. This study evaluated how often a critical finding is documented in the report's "impression" section and describes how an automated application can improve(More)
OBJECTIVE Communicating critical results of diagnostic imaging procedures is a national patient safety goal. The purposes of this study were to describe the system architecture and design of Alert Notification of Critical Results (ANCR), an automated system designed to facilitate communication of critical imaging results between care providers; to report(More)
PURPOSE In 2005, the Fleischner Society guidelines (FSG) for managing pulmonary nodules detected on CT scans were published. The aim of this study was to evaluate adherence to the FSG, adjusting for demographic and clinical variables that may contribute to adherence. METHODS Radiology reports were randomly obtained for 1,100 chest and abdominal CT scans(More)
INTRODUCTION Communication of critical imaging findings is an important component of medical quality and safety. A fundamental challenge includes retrieval of radiology reports that contain these findings. This study describes the expressiveness and coverage of existing medical terminologies for critical imaging findings and evaluates radiology report(More)
