Introduction: One of the key elements of success of health institutions is Standardization. This study introduces the methods and stages of electronic medical records standardization. Methods: The present study is a narrative review of the studies on the stages and methods of electronic medical records standardization. Results: The process of standardization of electronic medical records incl...
متن کاملElectronic Cigarette Topography in the Natural Environment
This paper presents the results of a clinical, observational, descriptive study to quantify the use patterns of electronic cigarette users in their natural environment. Previously published work regarding puff topography has been widely indirect in nature, and qualitative rather than quantitative, with the exception of three studies conducted in a laboratory environment for limited amounts of t...
متن کاملEffects of user puff topography, device voltage, and liquid nicotine concentration on electronic cigarette nicotine yield: measurements and model predictions.
INTRODUCTION Some electronic cigarette (ECIG) users attain tobacco cigarette-like plasma nicotine concentrations while others do not. Understanding the factors that influence ECIG aerosol nicotine delivery is relevant to regulation, including product labeling and abuse liability. These factors may include user puff topography, ECIG liquid composition, and ECIG design features. This study addres...
متن کاملSmokeless tobacco topography and toxin exposure.
This study examined the relationship between oral smokeless tobacco (ST) topographical measures and biomarkers of tobacco and carcinogen exposure. During 2 weeks of baseline ad libitum ST use, 54 male participants (mean age=32.1+/-7.5 years) were required to record the time each dip was placed in and removed from their mouths. Urine samples were collected twice during baseline and analyzed for ...
متن کاملPuffing Topography and Nicotine Intake of Electronic Cigarette Users
BACKGROUND Prior electronic cigarette (EC) topography data are based on two video analyses with limited parameters. Alternate methods for measuring topography are needed to understand EC use and nicotine intake. OBJECTIVES This study evaluated EC topography with a CReSS Pocket device and quantified nicotine intake. METHODS Validation tests on pressure drop, flow rate, and volume confirmed r...
