26. Electronic Clostridium difficileInfection Bundle Reduces Time to Initiation of Contact Precautions

Author

Dewart, Courtney M., Blanco, Natalia, Foxman, Betsy, and Malani, Anurag N.

Abstract

The impact of computerized order-entry bundles on timing of contact precaution initiation for C. difficileinfection (CDI) remains largely unexplored. Implementation of an electronic CDI prevention and management bundle that included an automatic isolation component significantly reduced time to initiation of contact precautions from 33.7 to 22.4 hours.Infect Control Hosp Epidemiol2016;242–244

27. Evaluating Risk Factors for Antimicrobial Resistance Using Electronic Health Record Data

Abstract

Antimicrobial resistance is a global threat to public health. To prevent antimicrobial resistance, improving antibiotic stewardship and tracking antibiotic-resistant infections are core actions recommended by the Centers for Disease Control and Prevention. In this work, I aimed to contribute to the field of knowledge in these areas by 1) identifying the association between a penicillin-class allergy label and ciprofloxacin coverage in community-onset urinary tract infection (UTI), 2) developing models to predict infection susceptibility to antibiotic treatment regimens among patients hospitalized with pneumonia in the intensive care unit setting, and 3) conducting a surveillance study of antimicrobial use and multidrug-resistant (MDR) Pseudomonas aeruginosa in an academic medical center. I achieved these aims using several different statistical methods. To quantify the association between having a documented penicillin-class allergy label and a UTI not covered by ciprofloxacin, I used causal inference methods including inverse probability weighting and mediation analysis to determine if the relationship was mediated by recent fluoroquinolone use. To predict infection susceptibility to treatment regimens among patients with pneumonia, I evaluated three penalized regression methods: LASSO, MCP, and SCAD. I developed models for susceptibility prediction at two different stages of the clinical diagnostic process: for all infecting bacteria to reflect the clinical situation when empiric treatment is selected, and for infections with gram-negative organisms only to reflect the updated clinical situation when more information about the organism is known. To quantify the relationship between antimicrobial use and MDR P. aeruginosa in the hospital setting, I used autoregressive integrated moving average models to account for autocorrelation and the time-dependent nature of the development of resistance following changes in antimicrobial use.From these analyses, I report that nearly 20% of patients had a documented penicillin-class allergy label. This label is a modest risk factor for an infection not covered by ciprofloxacin among hospitalized patients with community-onset UTI, which may be due in part to increased exposure to fluoroquinolones. For patients with pneumonia in the ICU, I show that for some treatment regimens, models fit using the SCAD penalty method are able to predict infection susceptibility with fair accuracy. In evaluating antimicrobial resistance among healthcare-associated P. aeruginosa isolates, I report a stable proportion of MDR isolates over the study period. However, I identified a significant increase in carbapenem resistance, which was associated with use of several antimicrobials. Of primary concern was an association with antipseudomonal carbapenem use, which also increased over time. From these findings, I suggest that one possible intervention to prevent the overuse of fluoroquinolones would be to evaluate the veracity of penicillin allergy labels at the point of care. With respect to predicting pneumonia infection susceptibility to treatment regimens, models with acceptable prediction accuracy may be incorporated into an electronic clinical tool; predicting infection susceptibility to specific treatment regimens based on patient-specific risk factors may support clinicians in empiric antibiotic selection. Finally, I demonstrate the importance of conducting local surveillance studies of antimicrobial use and resistance in order to identify areas for continued monitoring and interventions related to antimicrobial stewardship.
