Okay...lets get down to actually knowing what JCAHO is! It is an group that is HIRED by a facility on a national level that ASSISTS in helping a facility hold up to state and federal standards! It is NOT the law...but a reference PAID for by your facility to make sure they meet any rules and regs! In essence..a very very high paid consultant!!!!!!!
The facilities treat them like LAW, but they are consultants!
So..it is actually down to facility rules about attire..including footwear.
So check with your facility about the footwear you wish to wear.
*the reason you didn't see the rules and regs about it...proves my point
. I use to think of them higher than board...but less than fed...till I found out the truth during orientation at my last job...shocked me, but made more sense!
