Evaluation of carbapenem-resistant Enterobacteriaceae (CRE) Guideline Implementation in the Veteran’s Affairs Medical Centers Using the Consolidated Framework for Implementation Research

Abstract Background: Infections caused by carbapenem-resistant Enterobacteriaceae (CRE) and carbapenemase-producing (CP) CRE are difficult to treat, resulting in high mortality in healthcare settings every year. The Veteran’s Health Administration (VHA) disseminated guidelines in 2015 and an updated directive in 2017 for control of CRE focused on laboratory testing, prevention, and management. The Consolidated Framework for Implementation Research (CFIR) framework was used to examine contextual factors and identify best practices influencing implementation of the 2015 guidelines/2017 directive in VA Medical Centers (VAMCs).Methods: Qualitative interviews were conducted at 29 VAMCs with staff involved in implementing CRE guidelines at their facility. Survey and VHA administrative data were used to identify geographically representative large and small VAMCs with varying levels of CRE incidence. Interviews addressed perceptions of guideline dissemination, laboratory testing, staff attitudes and training, patient education, and technology support. Participant responses were coded using a consensus-based mixed deductive-inductive approach guided by CFIR. A quantitative analysis comparing CFIR constructs and emergent codes to sites actively screening for CRE (vs. non-screening) and any (vs. no) CRE positive cultures was conducted with a Fisher’s exact test.Results: Forty-three semi-structured interviews were conducted between 10/2017-8/2018 with laboratory staff (47%), Multi-Drug Resistant Organism Program Coordinators (MPCs, 35%), infection preventionists (12%), and physicians (6%). Participants cited the need for more standardized tools to promote effective communication (e.g., electronic screening). Participants also indicated that CRE-specific educational materials were needed for staff, patient, and family members. Quantitative analysis identified the following CFIR constructs as being significantly associated with CRE screening or presence of CRE: Leadership Engagement, Relative Priority Available Resources, Team Communication, and Access to Knowledge & Information. Conclusions: Effective CRE identification, prevention and treatment requires ongoing collaboration between clinical, microbiology, infection prevention, antimicrobial stewardship, and infectious diseases specialists. Our results emphasize the importance of leadership’s role in promoting positive facility culture, including increasing healthcare worker’s awareness of infection control and prevention for emerging pathogens, access to resources, improving communication and facilitating successful implementation of the CRE guidelines.
