I've made a few changes to the plaquenil risk calculator. A few of the changes were in the interest of user-friendliness, but the more important changes are as follows.
I removed the chloroquine calculations. I can't recall the last time I saw a patient taking this (as opposed to hydroxychloroquine) and I feel presenting it as an option was only a potential source of confusion or errors.
I included some sliders for adjusting height and weight for BMI calculations. On the surface this may seem cosmetic but it also allows for our metric system users (which I call the "smart ones") to enter these values in kilograms and meters instead of ponds and feet/inches.
I made the cumulative Plaquenil dose calculator a bit more robust. It originally only accepted a dose and a duration in months and years. However, I realized that 1) Sometimes dosages change and 2) sometimes doses are irregular.
For example, if a person takes 400mg bid x 1 year, then changes to 200mg qd x 1 year, you can now add rows to the calculator by pressing the "+" button. You can do this as many times as you like.
In addition, I realized that I was seeing a lot of patients that were taking dosages like this: 400mg every other day, with 200mg on the opposite days. I added a "qod" sig option that can cover these more difficult prescribing patterns.
Hopefully that'll cover the majority of our needs for these calculations. If you run into any other commonplace scenarios that I haven't covered please let me know.
