Supply of Supplements • Fresenius Kabi and Baxter (Calea) • Before start: Supplies to be shipped to sites • Need updated pharmacy contact and shipping address Dispensing • ICU pharmacist dispensing pharmacist • Sign signature log • Enteral supplements – no mixing needed • Parenteral supplements – Mixing required: Dipeptiven (Glutamine) + Selenium (AOX) + Normal Saline Enteral Products • Obtain appropriate enteral product • Infuse at 20 ml/hour for all patients • Generate pharmacy label (need 2 labels) Remove company label and staple to Form B Attach pharmacy label to bottle (maintain blinding) Enteral Dispensing Log Mixing of Parenteral Supplements Dipeptiven (Glutamine) + Selenium (AOX) + Normal Saline Final volume = 250 mls, hourly rate = 10 ml/hr. 1. Determine dose of Glutamine according to Normal weight • Normal Weight (kg) = height (cms) –100 cms • Dose of Dipeptiven = Normal wt. X 2.5 mls (This equals to Normal wt. X 0.35 gms of Glutamine or Normal weight X 0.5 gms of L-alanyl-L-Glutamine). 2. Dose of Selenium = 12.5 ml (500 micrograms) = 1.25 vial 3. Combine the Glutamine + Selenium and remove this volume from 250 ml of normal saline. 4. Replace normal saline with this mixture. Final volume =250 mls. Parenteral Worksheet: AOX Should be 10.8 ml/hr Parenteral Worksheet: GLN Should be 10.8 ml/hr Parenteral Worksheet: AOX+GLN Should be 10.8 ml/hr Parenteral Worksheet: Placebo Should be 10.8 ml/hr Expiration of Supplements • Selenium once opened: 24 hrs if refrigerated • Dipeptiven once opened: mix immediately • Once mixed, parenteral solutions have an expiration of 96 hrs room temperature – Can make in batches to last 3 days!! Enteral Supplements once opened: 24 hrs Parenteral Study Supplement Log Parenteral Label Dosages according to height (PN) If > 6 feet 5 inches (>196 cms) •Final volume of parenteral solution will be between 250-300 mls. •Can still use 250 mls bag of saline •If no normal saline to be used, use an empty sterile bag and add supplements to the bag (instead of removing all normal saline) •Final rate of solution will exceed 10 ml/hr •Central line needed but peripheral may be used (72 hrs max) Pilot Study: no one > 190 cms (6’3”) Nutrient Accountability Logs One log for each product except for normal saline Monthly Site Inventory Log Fax in to CERU monthly Temperature Log Fax in to CERU monthly Study Coordinator General Rules for Data Collection • • • • • • CERU to assign passwords, site # Dates DD/MMM/YYYY, 00:00 Click on + to expand menu or taxonomy Site Status Page: shows all patients Patient Status Page : colour coding Input warnings : help with query process Site Status Page Patient Status Page Duration of Data Collection For daily data from Study Day 1 until Day 30 unless ICU discharge (actual) or death occurs before day 30 EXCEPT the following: – Study Supplement Compliance: maximum of 28 days. – Microbiology: -7 days ICU admission to ICU discharge. – Antibiotics: -7 days ICU admission and stop dates may extend beyond ICU discharge. – Patients with ICU stay < 5 days and transferred to ward: collect all daily data from Study Day 1 and continue for 5 days in total (=120 hrs). Study Day 1 is from ICU admission to end of flowsheet. Study Day 2 and subsequent days are according to your 24 hr flowsheet Baseline Hypotension Respiratory Failure OK to wait Must be completed Logical sequence APACHE II May use existing APACHE score if available Lowest and highest values Score automatically generated Study Supplement Timelines Duration of supplements: • Minimum 5 days (120 hrs) • Maximum 28 days Start and stop dates and times Baseline Nutrition Dietitian to collect: • Prescribed kcal and protein (baseline) • Type of nutrition support • Start and stop date and times • Refer to Dietitian Manual Daily Data Study Day 1 is from ICU admission to end of your 24 hr flowsheet. Study Day 2 and subsequent days are according to your 24 hr flowsheet. Dietitian may help by collecting the location of feeding tube Daily Nutrition • Dietitian to collect the data and give to SC • Close to real time to ensure that patient is being fed adequately. • Use checklist (see sample in Dietitian Manual) Dietitian Checklist Study Supplement Compliance • Volumes must be monitored DAILY in real time. • If volumes < prescribed, need to report to CERU or provide explanation and take action to prevent recurrence.

If culture date> 72 hrs ICU admission, 2 questions will be asked to help determine suspicion of ICU acquired infection. Suspicion of ICU Infection • Is this culture a manifestation of a previously diagnosed infection? • Is this a routine surveillance swab? NEED TO ASK SITE INVESTIGATOR • If NO to both………………..flag for adjudication (to be done after ICU outcomes). Antibiotics Period of data collection starts 7 days prior to ICU admission and may extend beyond ICU discharge. If abx started > 72 hr ICU admission, 3 questions will be asked to help determine suspicion of ICU acquired infection. Suspicion of ICU Infection • Is this antibiotic prescribed for prophylaxis? • Is this a dose adjustment for an antibiotic ordered for a previous infection? • Is this a substitute for an antibiotic ordered for a previous infection? NEED TO ASK SITE INVESTIGATOR • If NO to ALL………………..flag for adjudication (to be done after ICU outcomes). ICU Outcomes All input warnings must be addressed before you can access this page. The input warnings will appear at the top of the Patient Status Page. This page MUST be completed before you can proceed to the next web pages Infection Adjudication All input warnings must be resolved Automatic listing of relevant clinical data (microbiology. antibiotics, daily data) that will enable the Site Investigator to adjudicate newly acquired ICU infections. Determination of ICU Infection Was this culture or the prescription of this antibiotic for a NEW ICU acquired infection? (after 72 hours of admission from ICU admission)? Yes Choose the appropriate Categories of Infection (1-12)* and if: Definite Yes or Probable Yes or Possible Yes No NO, because it is related to an infection previously diagnosed and adjudicated. NO, because it is NOT an infection Possible** NO *Categories of Infection: Appendix 8.2 **Definition of No: Appendix 8.3 END Probable* * NO END Hospital Outcomes 3 and 6 month f/up SF-36 at 3 and 6 months Investigator’s Confirmation Only appears once the ICU and Hospital outcomes have been completed and all input warnings have been resolved (Patient Status Page). SAE Reporting • Serious and Unexpected events – regardless of relationships to supplements • Initial report faxed within 48 hrs • Final report at day 30, ICU d/c, death or 10 days from becoming aware of SAE • Record the event, not the outcome (death) SAE Initial Report SAE Follow up Report Daily Monitoring • Enteral Study Supplement Volumes < 80 % prescribed: Protocol Violation Form >= 80 and < 100 %: Provide explanation • Parenteral Study Supplement Volumes < 90% prescribed: Protocol Violation Form >=90 and < 100%: provide explanation • SAEs: unexpected: report within 48 hrs, 10 days • Start of antibiotics > 72 hrs ICU admit, ask SI • Positive Cultures > 72 hrs ICU admit: ask SI Threats to Success • • • • Poor enrollment, competing studies. Inadequate delivery of study supplements. Inadequate delivery of enteral nutrition. Additional training needs? Questions?
