Ok,
Without knowing your average daily and ICU census, I can't make an assessment of correct pharmacist staffing. But at 35,000ER visits per year, you're not the busiest hospital on the block.
But,
If you don't have at least 1:1 pharmacist vs. tech ratio, then the department is not efficient... 1:2 is even better. You guys are more like 2:1... super inefficient.
Get rid of those pharmacists preparing IVs and Chemo. You don't need a full time pharmacist checking IV's all day...checking IV should take less than an hour per day if IV's are properly batched and prepared accordingly.
Batching IV means preparing typically used IVs day before.. and/or before it's needed...batching allows for a quick preparation. Then techs can label them at once... takes no time..and at 291 beds...you don't need that many IVs.
You got 3 pharmacists ($150,000 per year including benefits) doing $40,000 per year tech work. Your DOP is a dummy and probably should be demoted or fired and replaced...or get properly trained.
I don't want to believe your clinical pharmacists on the floor are up there making clinical rounds...I will give the benefit of the doubt and say they're probably processing orders while making interventions. What we call decentralized hybrid - clinical pharmacist. So if you have 2 decentralized pharmacists, then your 2 pharmacists downstairs can process orders for the rest of the hospital and still check the IVs.
You definitely need more techs to fill pyxis, prepare IVs etc. And the nurses should not have to come down to the pharmacy for any reason...that tells me that your tech support is short and the medications are not getting delivered efficiently.
Thank god typical DOPs run their department piss poor... job security for my industry.
