Hospitals across the country are struggling to deal with a shortage of one of their essential medical supplies.

Now drug companies say they won't be able to catch up with demand until next year. That leaves San Francisco General Hospital's materials manager, Reid Kennedy, in a fix. Kennedy is in charge of managing all the gloves, bandages, bedpans and IV solutions for all the medical floors, emergency room and operating room.
