In terms of the actual bag I carry, on light days I can be found with this nylon carry-all tote. After nearly four years of use, it's still going strong. It's water resistant, lightweight, and folds up into a neat little rectangle, perfect for travel. Here's a slightly more budget friendly option; however, when I consider how much I carry it (nearly daily), if you can splurge it's worth every penny. You really do get what you pay for. When I'm carrying my heavy laptop or binder full of notes for a long day, my go to is this. It's not the prettiest backpack, but the quality is great and it has lots of pouches, so I'm sure I'll be carrying this for years, through rotations and beyond.
As for the "doctor stuff," I only bring my stethoscope and gadget kit for the occasional patient exam, but come next year I'll be using them much more often!
Here are some adorable pouches to add a little organization to your bag:
