Do they improve care? Do they lower productivity? Are they difficult to use? Do they make the patient narrative harder to create and follow?   Many discussions […]

Using EHR-related Research to Guide EHR Design

by Jerome Carter on March 24, 2014 · 0 comments

It is difficult to find research-quality information that can aid in EHR design.   Too often, studies that discuss the effects of EHR systems on specific outcomes treat the EHR system as a monolithic entity…as a black box, really.   This view of EHR systems, while convenient from a research perspective, does little to help those of […]


Well, it is finally time to talk about proofs.   This might seem to be a rather esoteric topic for an EHR-focused blog, but actually it is quite relevant.   Software consists of a series of algorithms, and each algorithm is intended to work correctly 100% of the time.   Creating algorithms is very much a process of […]


Learning logic is not an esoteric endeavor, even if one is not interested in writing proofs.   Reasoning logically is a requirement in any field.   The rules of inference mentioned in the last post are used for deductive reasoning, which is an important skill.  An additional plus for me has been the effect that studying logic […]


My interest in learning discrete math was triggered by a desire to understand Petri nets.   I never really intended to learn how to do math proofs because they always seemed too obscure to be grasped by mere mortals.   Like most people, by the time I picked up a discrete math book, I had already been […]
