August Hops is a 50-year-old man who has been experiencing fever and chills and has not been feeling well over the past 4 days. He was admitted to our hospital yesterday. He was at home receiving home therapy with daptomycin 700 mg IV once daily (day 12 of a 14-day course) via PICC line for MRSA bacteremia, which he developed after having an appendectomy at an outside community hospital about a month ago. During that hospitalization, he also received a course of piperacillin–tazobactam for his appendicitis. His postoperative stay was complicated by a surgical site infection and MRSA bacteremia. He had his catheter removed at that time and was started on vancomycin, until he developed a rash and possible neutropenia. He was then switched to (and eventually sent home on) daptomycin. Prior to being discharged from the outside hospital, Mr Hops also received 7 days of fluconazole 200 mg PO daily for a urine sample from a Foley catheter that grew 100,000 colonies/mL of C. glabrata. He never grew Candida from any other site.
A set of blood cultures was drawn on this admission to our hospital and is showing no growth at 24 hours. His surgical site does not look infected. His PICC line was removed, and blood and urine cultures were drawn. Piperacillin–tazobactam was added to the daptomycin empirically on admission.
