Recommendations of Task Force Evaluation and Treatment of Nosocomial Sepsis Chair: T. Cox, Pharm.D. Members: Lakshmi Katikaneni, M.D.; Sarah Taylor, M.D.; Carlene Speaks, N.N.P.; Joan Demarest, R.N.; (NNP Alternate: Ashley Klum, N.N.P.) Charge: Develop guidelines (based on current evidence, best-practice guidelines, and MUSC patterns of practice and infection) for: Indications for which a sepsis evaluation should be performed (scoring system) Components of the sepsis evaluation Initial therapy and duration of therapy Recommendations: 1. Nosocomial Sepsis a. Definition: evaluation beyond 1st 72 hours of life excluding sepsis associated with a known source (e.g. not NEC, omphalitis, etc.) b. Indications for evaluation: Work group considered use of a scoring system to identify infants requiring a late onset sepsis evaluation based on clinical, laboratory, and risk factor criteria. Only one such scoring system was found in the literature. The investigators who developed this system recommend external validation of the scoring system in individual units before implementation of its use (Mahieu 2000, 2002). Recommendation of the work group is to defer the use of such a scoring system at this time in order not to delay implementation of a late onset sepsis pathway 2. Evaluation a. Cultures: i. Cultures of blood 1. Minimum blood culture volume = 1 ml. 2. Minimum 2 blood cultures for each sepsis work-up 3. Sources a. With central Line: One blood culture should be obtained from all central lines (excluding UAC and UVC) and one blood culture should be obtained by peripheral stick b. No central line: 2 peripheral blood cultures. 4. Consideration should be given to holding blood cultures for fungus if patient birth weight < 1000 g, there is evidence of thrombocytopenia, or history of frequent or prolonged antibiotic use. ii. Urine (catheter or suprapubic, not bagged) iii. CSF (if patient able to tolerate procedure. If patient is too unstable to tolerate procedure, a future attempt should be made as soon as possible after patient has been stabilized.) iv. All should be obtained prior to starting antimicrobial therapy. Once a decision is made to initiate a sepsis evaluation, cultures should be obtained and antibiotics started as soon as possible. Unnecessary delays should be avoided. If cultures These recommendations should be individualized for specific patients, as clinically indicated.

Nursing to document source of all cultures on laboratory forms 1. Blood = central or peripheral; catheter or stick 2. Urine = catheter or suprapubic 3. Choice of antimicrobial therapy a. Use of any antimicrobial requires assessment for potential contraindications to therapy prior to starting treatment b. Hemodynamically unstable or central line in place > 10 days (Maki 2002) i. Vancomycin + piperacillin/tazobactam ii. “Hemodynamically unstable” defined as requiring fluid boluses or vasopressors to maintain blood pressure c. Hemodynamically stable and central line, if present, in place < 10 days i. Nafcillin and gentamicin d. Consider addition of antifungal therapy for patients with birth weight < 1,000 grams, thrombocytopenia, significant drop in platelet count from previously known values, or history of frequent or prolonged antibiotic use e. All antimicrobials should be infused through central line if present. Nursing should notify MD or NNP if drug compatibility issues preclude this. 4. Analysis of culture results a. We recommend that methods be developed to distinguish true infection with coagulase negative staphylococci (CoNS) from contaminated blood cultures. Potential options include colony counts and species identification on all positive blood cultures for CoNS. The Microbiology Laboratory is not currently set up to perform these functions; however, there is the potential that they could be. b. All cultures negative at 48 hours -> d/c antibiotics (antifungals may be continued x 72 hours (Schelonka 2003) pending negative results) c. All positive urine and CSF cultures should be treated based on organism identification and susceptibility. d. Positive blood cultures i. Practitioner notified by Microbiology Laboratory of Gram Positive organism 1. Change nafcillin to vancomycin pending definitive ID. 2. Repeat blood culture before changing antibiotics. 3. Final antibiotic therapy should be guided by organism identification and susceptibility. ii. Contaminant organisms requiring no further antibiotic therapy 1. Corynebacterium 2. Propionibacterium 3. Penicillium (Stoll 2002) 4. Diphtheroids were also included among contaminant organisms in this reference; however, according to Dr. Johnson some may be true pathogens. iii. Culture positive for (other than contaminant organisms) Follow recommendations on Table 1 These recommendations should be individualized for specific patients, as clinically indicated.

Patients with positive central line cultures due to the following organisms require immediate line removal: 1. S aureus (Benjamin 2001) 2. Gram-negative rods (Benjamin 2001) 3. Fungi – (IDSA guidelines) These recommendations should be individualized for specific patients, as clinically indicated.
