Everything on this list:
100 items that disappear first in a Disaster.

This along with a lot more useful information is in my Preparedness manual which can be downloaded at:

One thing not on that list which should probably be at the top is Quikclot. In a true emergency situation, hospitals will be overwhelmed and you will probably need to perform your own triage.
A bad bleed which is easily treated now could easily lead to death then. IMO, not enough thought is given to medical supplies. One could have a years worth of food and water, but if they get a bad cut, it could be game over.
Food for thought.
