Background Deploying accurate computable phenotypes in pragmatic trials requires a trade-off between precise and clinically sensical variable selection. In particular, evaluating the medical encounter to assess pattern leading significant impairment or distress indicative of disease is difficult modeling challenge for emergency department. Objective This study aimed derive validate an electronic health record–based phenotype identify department patients with opioid use disorder using...

Emergency departments (EDs) frequently care for individuals with opioid use disorder (OUD). Buprenorphine (BUP) is an effective treatment option patients OUD that can safely be initiated in the ED. At present, BUP rarely as a part of routine ED care. Clinical decision support (CDS) could accelerate adoption ED-initiated into emergency

Abstract Computerized clinical decision support (CDS) faces challenges to interoperability and scalability. Centralized, web-based solutions offer a mechanism share the cost of CDS development, maintenance, implementation across practices. Data standards have emerged facilitate rapid integration such third-party CDS. This case report describes scalability an integrated, intervention for EMergency department-initiated BuprenorphinE opioid use Disorder which will soon be evaluated in trial 20...

Buprenorphine (BUP) can safely and effectively reduce craving, overdose, mortality rates in people with opioid use disorder (OUD). However, adoption of ED-initiation BUP has been slow partly due to physician perception this practice is too complex disruptive. We report progress the ongoing EMBED (EMergency department-initiated BuprenorphinE for Disorder) project. This project a five-year collaboration across five healthcare systems goal develop, integrate, study, disseminate user-centered...

Angiosarcomas are high-grade endothelial tumors remarkable for their rarity and malignant behavior. Primary calvarial angiosarcoma is an extremely rare entity its behavior usually sets it apart from other types. We highlight the successful management of cranial using a multidisciplinary approach.We present 16-year-old male who was first noted to have right-sided parietal mass that biopsied in 2008. Pathology initially thought be Kaposiform hemangioendothelioma. The patient subsequently...

To measure the thicknesses of inner layers macula in both eyes patients with unilateral primary open-angle glaucoma (POAG) and compare them normal control eyes.This prospective, cross-sectional pilot study enrolled POAG, who had visual field defect only 1 eye, controls a eye examination. Horizontal vertical B-scan images centered on fovea were obtained using spectral domain optical coherence. Semiautomatic delineation segmentation retina performed to evaluate macular retinal nerve fiber...
