A 64-year-old female admitted for shortness of breath, weakness, and fatigue with a PMH of HTN, DM, heart failure, atrial fibrillation, and end-stage renal disease (ESRD) had positive MSSA blood cultures from admission. A definitive source for the MSSA BSI was not determined but assumed to be foreign body material (tunneled dialysis catheter, Foley catheter, and implantable cardiac device). She was initiated on ceftriaxone 2 g every 24 h on day 3 and cultures cleared on day 8. She received 4 weeks of ceftriaxone (25 days inpatient and 3 days outpatient).
A 35-year-old female was admitted for fever with swelling and pain at the site of the peripherally inserted central catheter (PICC) in her left arm. She had a PMH of gastroparesis with multiple abdominal surgeries and was reliant on total parenteral nutrition. Blood cultures revealed MSSA, and her PICC was removed for 48 h before a new one was placed. She received ceftriaxone 1 g every 24 h on days 1–3. Ceftriaxone was switched to oxacillin 2 g every 6 h on day 4. She was changed back to ceftriaxone 2 g every 24 h on day 12, then discharged to a long-term acute care (LTAC) facility on day 23. She continued ceftriaxone at LTAC for 8 additional days.
