I do not take pills too often, mostly it's something for a headache once every couple of months or allergy whenever the flowers are in bloom. However, there are people around us that take many medications daily, especially people with chronic conditions and the elderly. Keeping track of medications within an electronic medical record (EMR) for such patients is, not surprisingly, a challenge: the patient may switch to a generic drug, but the EMR lists it under a brand name, the dosage may be off, or instead of orally the patient now takes the drug intravenously. Reconciling what the patient is actually taking and what is recorded in the system is a boring and daunting task: one has to pay attention to details like "4mg" vs "7 mg" and meticulously compare drug names -- not something a busy physician can spend a lot of time on. However, this problem shows up every time the provider's data is out of date. This could be during an emergency visit to the hospital or during a routine visit to a physician or a specialist. Keeping track of the current medications is important when adjusting or prescribing new treatment and as to avoid prescribing drugs and procedures that may be incompatible with current medications.
The Human-Computer Interaction Lab (HCIL) at University of Maryland took on this challenge and produced a simple, yet powerful way to automate medication list reconciliation (a medical term for a problem described above). Computers are good at exact comparisons -- and that's what researchers at HCIL used to find discrepancies in dosage, path of administration, and frequency for the same drugs coming from two different lists. Inexact and ambiguous matches are then presented to the user who can decide how to proceed. Through intuitive highlighting and animation that makes it easier to follow the process they have made reconciliation quick and managed to reduce human error.
What I appreciate the most about this interface is its simplicity (it is a list after all). It is easy to identify the drugs that match and the drugs that differ, drugs that are unique to the hospital and drugs that are unique to a patient. Similar drugs are aligned on the same line visually encoding the relationship. The details that differ between similar drugs are subtly highlighted in yellow as to not crowd the overall picture with too much information. The careful use of animation makes a seemingly boring task more fun. Power users may skip the animation and use the overhead menu instead.
I am very impressed with HCIL's continued success and if I ever find myself having to manage 20 different drugs, I would want my physician to use Twinlist for reconciliation! They took a mundane task that no one likes and turned it into an easy exercise for the eyes improving medical care in the end. Having seen some EMRs and what a tangled mess they are, I believe it is solutions like this -- making mundane data entry/cleaning/updating -- that can significantly improve care and save doctors some precious time.
