Organizational, Cultural, and Psychological Determinants of Smart Infusion Pump Work Arounds: A Study of 3 U.S. Health Systems.

OBJECTIVES: We investigated nurse perceptions of smart infusion medication pumps to provide evidence-based insights on how to help reduce work around and improve compliance with patient safety policies. Specifically, we investigated the following 3 research questions: (1) What are nurses' current attitudes about smart infusion pumps? (2) What do nurses think are the causes of smart infusion pump work arounds? and (3) To whom do nurses turn for smart infusion pump training and troubleshooting? METHODS: We surveyed a large number of nurses (N = 818) in 3 U.S.-based health care systems to address the research questions above. We assessed nurses' opinions about smart infusion pumps, organizational perceptions, and the reasons for work arounds using a voluntary and anonymous Web-based survey. Using qualitative research methods, we coded open-ended responses to questions about the reasons for work arounds to organize responses into useful categories. RESULTS: The nurses reported widespread satisfaction with smart infusion pumps. However, they reported numerous organizational, cultural, and psychological causes of smart pump work arounds. Of 1029 open-ended responses to the question "why do smart pump work arounds occur?" approximately 44% of the causes were technology related, 47% were organization related, and 9% were related to individual factors. Finally, an overwhelming majority of nurses reported seeking solutions to smart pump problems from coworkers and being trained primarily on the job. DISCUSSION AND CONCLUSIONS: Hospitals may significantly improve adherence to smart pump safety features by addressing the nontechnical causes of work arounds and by providing more leadership and formalized training for resolving smart pump-related problems.

A Systematic Review of Vancomycin Dosing and Monitoring in Burn Patients.

Vancomycin pharmacokinetics are significantly altered following burn injury, requiring a higher total daily dose to achieve adequate serum concentrations. Wide interpatient variability necessitates close, frequent monitoring of serum concentrations for efficacy and safety. The aim of this study is to systematically evaluate published data regarding vancomycin pharmacokinetic alterations in burn patients, to determine whether evidence-based recommendations for dosing and monitoring can be formulated, and to identify future research opportunities. The systematic review included studies published in English, involved human subjects with at least a 10% TBSA burn who received vancomycin intravenously, and obtained serum concentration(s). Database searches returned 130 titles for review. Twelve studies met a priori inclusion criteria. The most common dosing regimens in adult and pediatric patients were 5 to 20 mg/kg/dose every 6 to 8 hours. Mean trough concentrations were 7.24 ± 1.5 mg/L. Only 12.5% of reported trough concentrations were within the currently recommended range of 10 to 20 mg/L. Although no consistent dosing recommendations were provided, all studies recommended close monitoring of trough concentrations. Based on limited clinical outcomes data, standardized recommendations for vancomycin dosing and monitoring in burn patients cannot be made. Higher total daily doses (40-70 mg/kg/day) and increased dosing frequency (every 6-12 hr in adults) may be necessary to achieve current target trough concentrations. Future research goals include prospective investigation of clinical outcomes related to initial doses, loading doses, monitoring peak and trough concentrations, and adverse effects. Further data on the effects of burn size, concomitant diseases, inhalation injury, and time since injury may improve the accuracy of vancomycin dosing in burn patients.
