1 Appendix: Survey AKI Dialysis Antibiotics Thank you for participating in this research project. We will use the information collected from this survey to learn about how pharmacists make antibiotic dosing recommendations in patients receiving novel renal replacement therapies (RRT) in the intensive care unit. Study results may be presented in scientific conferences and/or peer-reviewed journals. The information you provided will be recorded anonymously. Directions You will find the case of a highly catabolic critically ill patient with acute kidney injury (AKI) and sepsis who will receive sustained low-efficiency dialysis (SLED) administered daily to maintain metabolic and fluid control. There are few published recommendations for SLED. Any available antibiotic dosing information from the package insert for IHD 3x/week will be provided. Published antibiotic dosing information for SLED will be provided when available. There will be 6 antibiotics to consider for this patient. Please provide your best recommendation even though you may not have experience in SLED. This survey has 7 pages and will take approximately 30 minutes to complete. If you have any questions regarding the survey, please contact the principal investigator of this project Bruce A. Mueller at muellerb@med.umich.edu Thank you again for your time. Please press the button to proceed to the survey. 2 CLINICAL CASE Given the following hypothetical case, please provide the antibiotic dosing regimen you would recommend for SLED below. A 58-year-old man (84 kg) is admitted to the ICU from a nursing home for the treatment of septic shock and anuric acute kidney injury. On admission, patient is febrile, BUN 90 mg/dL, blood pressure 90/60 mmHg, WBC 14x103/mm3. The patient is 10% fluid overloaded. Extended spectrum antibiotics need to be initiated and the following are being considered for use: cefepime, ceftaroline, daptomycin, levofloxacin, meropenem, piperacillin/tazobactam. Physicians intend to achieve azotemic control and euvolemia with SLED. SLED protocol: Daily for 8 hours using a F8 (low-flux) dialyzer QB = 200 ml/min, QD = 200 ml/min 3 Q1 Drug 1/6: Cefepime FDA recommended dosing for IHD 3x/week: "1000mg on day 1, then 500 - 1000mg every 24 hours thereafter. On dialysis days, cefepime should be administered following dialysis at the same time each day if possible." There is no literature-based cefepime dosing recommendation in SLED. Please provide your recommended cefepime dosing for daily SLED for our hypothetical patient. Dose and Interval (e.g. X mg every X hour) _________________________ Administration time relative to dialysis (e.g. immediately after dialysis) ______________________ Any dosing adjustments while SLED is running? _________________________ Additional comments regarding your regimen _________________________ Q2 Drug 2/6: Ceftaroline FDA recommended dosing for IHD 3x/week: "200 mg IV (over 1 hour) every 12 hours administer after dialysis on dialysis days" There is no literature-based ceftaroline dosing recommendation in SLED. Please provide your recommended ceftaroline dosing for daily SLED for our hypothetical patient. Dose and Interval (e.g. X mg every X hour) _________________________ Administration time relative to dialysis (e.g. immediately after dialysis) ______________________ Any dosing adjustments while SLED is running? _________________________ Additional comments regarding your regimen _________________________ Q3 Drug 3/6: Daptomycin FDA recommended dosing for IHD 3x/week: "4 mg/kg (cSSSI) or 6 mg/kg (S. aureus bloodstream infections) once every 48 hours following dialysis on dialysis days." Published SLED recommendation: 6mg/kg over 30min daily. The SLED parameters used in studies are: F60S (high-flux) dialyzer, QD 100mL/min, QB 200mL/min, a dialysis duration of 12 hours (Reference 1, Reference 2). Please provide your recommended daptomycin dosing for daily SLED for our hypothetical patient. Dose and Interval (e.g. X mg every X hour) _________________________ Administration time relative to dialysis (e.g. immediately after dialysis) ______________________ Any dosing adjustments while SLED is running? _________________________ Additional comments regarding your regimen _________________________ 4 Reference 1.

Nephrol Dial Transplant. 2010;25(5):1537-1541 Q4 Drug 4/6: Levofloxacin FDA recommended dosing for IHD 3x/week: "500 mg initial dose, then 250 mg every 48 hours OR 750 mg initial dose, then 500 mg every 48 hours" Published SLED recommendation: No specific dosing recommendation provided in the published study. Levofloxacin should be administered after SLED (Reference 3) Please provide your recommended levofloxacin dosing for daily SLED for our hypothetical patient.

Q5 Drug 5/6: Meropenem FDA package insert data for dosing for IHD 3x/week: "There is inadequate information regarding the use of meropenem in patients on hemodialysis. In patients with creatinine clearance <10mL/min, half of the recommended dose should be given every 24 hours." Published SLED recommendations: 0.5-1g q8hr, administer 6hrs before dialysis. SLED parameters use in the study are: F60S (high-flux) dialyzer, mean QD and QB is 160mL/min, and a dialysis duration of 8 hours (Reference 4). 1g q12hr before dialysis. SLED parameters used in the study are: mean QD is 170ml/min and QB is 160ml/min for 8hr (Reference 5).
