Outflow: Visualizing Patient Flow by Symptoms and Outcome
نویسندگان
چکیده
Electronic Medical Record (EMR) databases contain a large amount of temporal events such as diagnosis dates for various symptoms. Analyzing disease progression pathways in terms of these observed events can provide important insights into how diseases evolve over time. Moreover, connecting these pathways to the eventual outcomes of the corresponding patients can help clinicians understand how certain progression paths may lead to better or worse outcomes. In this paper, we describe the Outflow visualization technique, designed to summarize temporal event data that has been extracted from the EMRs of a cohort of patients. We include sample analyses to show examples of the insights that can be learned from this visualization.

A Simplified Solution for Advection Dominated Accretion Flows with Outflow
The existence of outflow in the advection dominated accretion flows has been confirmed by both numerical simulations and observations. The outow models for ADAF have been investigated by several groups with a simple self similar solution. But this solution is inaccurate at the inner regions and can not explain the emitted spectrum of the flow; so, it is necessary to obtain a global solution for...
متن کاملEvaluation of left ventricular outflow tract obstruction with 4D phase contrast in patients with hypertrophic cardiomyopathy
Background Patients with hypertrophic cardiomyopathy (HCM) develop left ventricular outflow tract (LVOT) obstruction due to combination of asymmetric septal hypertrophy and systolic anterior motion of the mitral leaflet. Degree of LVOT obstruction is an important predictor in patient symptoms and clinical outcome. LVOT obstruction is currently assessed by Doppler echocardiography (echo) using p...
متن کاملNumerical simulation of incompressible turbulent flow in shrouded disk system with radial outflow
The flow behavior inside the shrouded disk system is of importance in appropriate design of turbomachinery cavities and turbine test cell hydraulics dynamometer. The turbulent incompressible flow is analyzed for the shrouded disk system with axial clearance. The flow core behaves as a Batchelor type structure when a weak inflow is imposed on the disk cavity. By increasing the inflow, the centra...
متن کاملSTUDY OF THE ASSOCIATION BETWEEN ACTIVITY LEVEL AT ONSET OF SYMPTOMS AND PATIENT OUTCOME OF F IRST ACUTE MYOCARDIAL INFARCTION
This study sought to compare the clinical features and outcome of a first acute myocardial infarction (AMI) with onset of symptoms during or within 30 minutes of exercise, at rest and in bed. Information collected using a standard questionnaire was used to relate activity at the onset of symptoms and in-hospital outcome in 500 consecutive patients admitted to our heart center with a first ...
