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.
A 55-year-old male was admitted with severe pain secondary to a fall with a PMH for HTN and advanced alcoholic cirrhosis. Blood cultures on day 1 were positive for MSSA. Oxacillin 2 g every 4 h was given on days 3–12. The patient achieved MC but failed to achieve CC (WBCs did not normalize within 7 days). On discharge (day 12), he was switched from oxacillin to ceftriaxone 2 g every 24 h. The patient died from liver disease complications 7 days after discharge.
