Adjusted vs Total Body Weight-Based Dosing of Sedation and Analgesia Used in the Intensive Care Unit.

Background: The purpose of this study was to evaluate if dosing fentanyl, dexmedetomidine, and propofol based on ideal or adjusted vs actual weight in patients would decrease overall opioid and sedative use. Methods: This was a retrospective chart review comparing adjusted vs actual weight-based dosing protocol of mechanically ventilated (MV) intensive care unit (ICU) adult patients who required fentanyl and either propofol or dexmedetomidine. Results: A total of 261 patients were included in which 101 patients were in the actual weight group and 160 patients were in the adjusted weight group. Total doses per MV day of fentanyl was 1042 ± 1060 µg in the actual weight group vs 901 ± 1025 µg in the adjusted weight group (P = .13). Total doses per MV day of midazolam was 20 ± 19 mg in the actual group vs 15 ± 19 mg adjusted group (P = .02). Average MV days was 8.2 vs 7.1 days, ICU length of stay was 10.6 vs 9.4 days, and self-extubation rates were 17.8% vs 4.4% in the actual group and adjusted group, respectively. Conclusion: Total midazolam doses per MV day were lower in the adjusted group. No significant change was seen in MV days, ICU length of stay, or self-extubation rates.

A matched-control evaluation of an antifungal bundle in the intensive care unit at a university teaching hospital.

BACKGROUND: Antimicrobial use bundles are becoming a common means of implementing antimicrobial stewardship initiatives in the hospital setting. Although the utility of these bundles has been described for many disease states, their adoption for antifungal therapy management is largely unknown. OBJECTIVE: Our objective was to assess the utility of an antifungal bundle protocol in limiting excessive use of echinocandins in the intensive-care inpatient setting. METHODS: In this matched-control evaluation, pre-protocol control patients were matched with each prospective patient in a 2:1 ratio using five demographic and clinical characteristics. The impact of the antifungal bundle protocol on caspofungin days of therapy, drug costs, and adherence to bundle criteria was assessed. RESULTS: A significant reduction in median days of caspofungin therapy (4.00 vs. 2.00 days, p = 0.001) was found in the bundle group. Most of this reduction in use was realized in the medical ICU (p = 0.002) as opposed to the surgical ICU (p = 0.188). CONCLUSIONS: Use of an antifungal bundle approach appears to facilitate a reduction in caspofungin use in the ICU without adversely affecting patient outcomes. Further trials are needed to assess the utility of such bundles in providing antimicrobial stewardship for antifungal drug use.

Impact of a Multimodal Antimicrobial Stewardship Program on Pseudomonas aeruginosa Susceptibility and Antimicrobial Use in the Intensive Care Unit Setting.

Objective. To study the impact of our multimodal antibiotic stewardship program on Pseudomonas aeruginosa susceptibility and antibiotic use in the intensive care unit (ICU) setting. Methods. Our stewardship program employed the key tenants of published antimicrobial stewardship guidelines. These included prospective audits with intervention and feedback, formulary restriction with preauthorization, educational conferences, guidelines for use, antimicrobial cycling, and de-escalation of therapy. ICU antibiotic use was measured and expressed as defined daily doses (DDD) per 1,000 patient-days. Results. Certain temporal relationships between antibiotic use and ICU resistance patterns appeared to be affected by our antibiotic stewardship program. In particular, the ICU use of intravenous ciprofloxacin and ceftazidime declined from 148 and 62.5 DDD/1,000 patient-days to 40.0 and 24.5, respectively, during 2004 to 2007. An increase in the use of these agents and resistance to these agents was witnessed during 2008-2010. Despite variability in antibiotic usage from the stewardship efforts, we were overall unable to show statistical relationships with P. aeruginosa resistance rate. Conclusion. Antibiotic resistance in the ICU setting is complex. Multimodal stewardship efforts attempt to prevent resistance, but such programs clearly have their limits.
