Abscess on buttocks

Just wanting advice. I work in home health and we have been seeing a patient for a few weeks now. Initially, he had been having dressing changes 3 times a day in the hospital. We have been doing once a day. His wife refuses to do the packing so we have to do the wound care. So, we got it to once a day. We have been doing that but I am just wondering if that is still the way we need to do it. He was supposed to go to the doctor last week but changed the appt cuz he didn't have the money to go to the MD. So, he will go this week. Just wanting advice. We are packing using nugauze and normal saline and covering with 4x4's. The tunneling has gotten a lot better and it is healing from the inside out.. Nevertheless, just wondering if once a day is too much.
