To determine renal cancer incidence in simple cyst-appearing masses detected at unenhanced computed tomography (CT).Institutional review board approval and an informed consent waiver for this retrospective HIPAA-compliant study were obtained. Patients who had with homogeneous water attenuation, hairline-thin smooth walls, no calcifications or septations identified by applying a validated natural language processing algorithm to radiology reports 15 695 unique patients underwent abdominal CT...
Delayed diagnosis of Kawasaki disease (KD) may lead to serious cardiac complications. We sought create and test the performance a natural language processing (NLP) tool, KD-NLP, in identification emergency department (ED) patients for whom KD should be considered.We developed an NLP tool that recognizes diagnostic criteria based on standard clinical terms medical word usage using 22 pediatric ED notes augmented by Unified Medical Language System vocabulary. With high suspicion defined as...
The objective of our study was to determine the performance 3-T multiparametric MRI (mpMRI) for prostate cancer (PCa) detection and localization, stratified by anatomic zone level, using Prostate Imaging Reporting Data System version 2 (PI-RADSv2) whole-mount histopathology (WMHP) as reference.

Purpose This study aimed to determine the costs associated with prostatic artery embolization (PAE) performed in hospital and outpatient-based lab (OBL) settings. Methods Procedures were similarly equipped procedure suites located within a tertiary or OBL. Time-driven activity-based costing (TDABC) was utilized calculate procedural incurred by institution. Process maps created describing personnel, space, equipment, materials. The time duration of each step recorded independently nurse...
OBJECTIVE. The purpose of this study is to determine the overall and sector-based performance 3-T multiparametric MRI for prostate cancer (PCa) detection localization by using Prostate Imaging-Reporting Data System version 2 (PI-RADSv2) scoring segmentation compared with whole-mount histopathologic analysis. MATERIALS AND METHODS. Multiparametric examinations 415 consecutive men were thin-section A genitourinary radiologist pathologist collectively determined concordance. Two radiologists...
Abstract Individuals diagnosed with colorectal adenomas high-risk features during screening colonoscopy have increased risk for the development of subsequent and cancer. While US guidelines recommend surveillance at 3 years in this population, uptake is suboptimal. To inform future interventions to improve uptake, we sought assess rates identify facilitators a large integrated health system. We utilized cohort patients diagnosis ≥ 1 tubular adenoma (TA) (TA cm, TA villous features,...

INTRODUCTION: There have been a myriad of efforts to address suboptimal colorectal cancer (CRC) screening rates in the United States (US). Individuals with high-risk colon polyps detected during colonoscopy 2- 5-fold increased risk for future development CRC; however, there are few directed towards optimizing reduction this group. We examined surveillance uptake patients large, academic healthcare system. METHODS: \We identified cohort patients: 1) age 50–75; 2) colonoscopic diagnosis...
Introduction: Adenoma detection rate (ADR) is inversely associated with risk of interval colorectal cancer (CRC), advanced-stage CRC, and CRC-related mortality. ADR a critical screening colonoscopy quality indicator; however, it requires manual data extraction from pathology reports which labor-intensive. We developed natural language processing (NLP) algorithm that automates measurement at health system provider levels to address this challenge. then aimed validate the NLP against chart...

Introduction: High quality screening colonoscopy is the hallmark of effective colorectal cancer (CRC) prevention. However, continuously monitoring indicators for providers and health systems remains a challenge. We developed validated natural language processing (NLP) tool to automatically measure 4 intraprocedural improvement (QI) metrics characterized its performance. Methods: implemented this initiative in large academic healthcare system that performs >15,100 colonoscopies yearly 6...
