Daily cleansing with iodine swabs are the standard where I work- no matter how long the foley had been in. However I expect this to change soon, as it's no longer evidence based practice. Mild soap and water work just as well.
Thank you for all of your responses. There is no standard in this clinic. when I taught my pt's family to do daily care only and one of the reach MD question me and other RN stated she used providone while she worked in the hospital.
