Patient safety is one of the main driving forces behind calls for better EHR systems and, as a result, EHR design quirks and flaws are receiving more attention.   Thomas Payne has provided a very insightful analysis of EHR safety issues in a recent BMJ Quality & Safety commentary (1). As part of the commentary he […]

As you read this, I am away enjoying the mountains.   As always, I take plenty of reading material on vacation because I can study with fewer distractions. While ruminating over what to take along, I realized how much reading blogs has become a part of my search for new ways of looking at problems, as […]

by Jerome Carter on January 13, 2014

Finally, I have had time to play with Python.   I have been trying to find time since last spring when I got my shiny new MacBook Pro.   Having spent recent years using C-inspired languages that are compiled and strictly typed, Python is proving to be a refreshing change.  Python can be used interactively, which makes […]

Here is the definition of a relation taken from Discrete Mathematics with Applications, by […]

Mathematics and Clinical Concepts, Part IV: Exploring Sets

by Jerome Carter on November 4, 2013

Everything can be expressed as a set—the rooms in a building, the providers in a practice, penicillins—everything.  When one studies the basics of set theory – unions, intersections, subsets and the like—the concepts seem so simple, even obvious, that it is difficult to believe that Georg Cantor  had to dream them up and then convince […]
