I agree with the last poster, whose name will be protected for personal reasons, that there is not a single industry on this planet that does not have shortages. Look at the gas shortage of the Seventies, the bread, milk and toilet paper shortages during every snow threat in the East, heck, even our cafeteria runs out of cups! So to demand that there cannot be any shortages is fantasy.

As for par levels, that is a dynamic exercise that will always change. Your best bet, after you've established how many days supply you wish to keep on hand, is to monitor usage over a length of time you determine.

I used to inventory the fast movers every week, and just listen for usage of unusual items. Because of that practice, I would work to ensure a week's worth of the fast movers. To paraphrase a old adage, the price of perpetual is constant vigilance! You will have to depend on ALL your co-workers, pharmacist included, to let you know when things are moving AND taking the responsibility of writing things down, not just telling you.

Par levels are realistically any quantity you feel comfortable with. If you can maintain 15 turns with a two-week par level, that's fine. If your space requirments limit your inventory to just a few days, that's what you have to live with. Find what fits and go with it!

Experience is a big help--you eventually just KNOW what the fast, big movers are.
I also get a daily report from IT detailing every patient charge for the last 24 hours. It is sorted by drug name, so I can see immediately how many famotidine vials or Coreg 12.5 were used. This is an emormous help, for the very reasons you have described. Rarely does anyone, tech or pharmacist, come to me to say we're having a run on Remicade. Maybe your IT dept can work for get you a similar report. Never hurts to ask!!

i agree with one of the previous posters. It's all about experience. I walk my shelf everyday and i know what is being used. Our par levels are set and continually changed...drugs come, drugs go. We use Omnicell and they reports that tell me the items that have not been used in a while and we will lower those pars. the longer you are there the more you will know your inventory pretty well
