Hello. The way to write down visit frequency took me awhile too. 2w1 means 2 times a week for 1 week. 3w2 means 3 times a week for 2 weeks. Or you could write 15 month 1 for an every other day dressing change ( 15 times a month for 1 month. It is sometimes difficult to determine what frequency is best. Sometimes I like to taper down...like 3w1, 2w1, 1w2. Or sometimes 2w2 then 1w3. It really depends on what you are seeing the person for...is it teaching, wound care, CV checks, IVs....each thing and person and their support system makes each case very different in their needs thus visit frequency. Hope this jumbled answer makes some sense to you!
