DynaMed Plus
UpToDate
DSM-5
WikiEM
I’ve used BMJ Best Practices a few times but prefer DynaMed and UpToDate.
Amion so I can easily check my call schedule
Medscape - quicker and more readable for checking pharm dosing, MOA, contraindications, AEs, etc. than UpToDate if I don’t need more detailed info.
In med school I used the above apps and the following:
Murmur Pro to periodically review heart murmurs
American College of Cardiology Guidelines
NCCN Guidelines
I used VisuaDx a few times
Epoccrates - paid for a full subscription but honestly didn’t end up using it that much. I was able to get the exact same info from UpToDate, DynaMed Plus, and Medscape all of which were free.
