It's great! It's hosted by a surgical resident, educational, and interesting. I prefer it to sawbones as it aims to educate but is entertainig in the process (whereas sawbones seems to aim to entertain but is also educational). It can be a bit tangiential at times (the host often describes the history of things directly related to the subject of the podcast) but these tangents are usually pretty interesting. Search google for legends of surgery Harvey Cushing episode 42.
If you want purely educational medical audio, check out the MKSAP audio collection. Dry as a bone, but detailed enough to fulfill its goal: to get you to pass the American board of internal medicine exam.
