Implementing an Electronic Screening Tool to Identify Patients at Risk for Candida auris

Background: Candida auris is an emerging fungus that presents a serious threat to healthcare facilities. Because Chicago is a locus of high prevalence, the Illinois Department of Public Health (IDPH) released guidelines for acute-care hospitals to screen and isolate patients who are directly admitted from either a skilled nursing or long-term acute-care facility (SNF or LTAC) with a tracheostomy or on a ventilator. This project was undertaken to evaluate applicability of IDPH criteria to our inpatient population and to develop effective tools to implement a surveillance system. Methods: To assess IDPH criteria, we reviewed local case epidemiology and conducted a point-prevalence survey of all inpatients on May 22, 2019. To implement a new surveillance program, we convened a multidisciplinary team to assess the functionality of the electronic health record (EHR), to create clinician education, and to develop new electronic tools. Results: Between June 2018 and August 2019, 20 unique C. auris patients were admitted to our facility, and only 2 (10%) met IDPH criteria. During the point-prevalence survey, 609 inpatients were assessed, and only 7 (1%) met IDPH criteria (Table 1). Therefore, we created a new surveillance program tailored to our local epidemiology. To do this, we convened a multidisciplinary team with representatives from infection prevention, nursing informatics, patient care, microbiology and information technology (IT). The IT build took 5 months, and the work products included a screening questionnaire integrated into the nurse admission navigator, new microbiology laboratory orders for C. auris culture, a new internal isolation category that we deemed prior location-based isolation (PLI), and an electronic report to automatically aggregate data. To streamline workflow, best-practice alerts (BPAs) were designed to automatically order isolation and laboratory tests based on responses to the admission questionnaire (Fig. 1). Additionally, tools were created catch missed opportunities for isolation and to automatically update isolation status based on final culture results. Conclusions: Local epidemiology must be considered when designing C. auris surveillance programs. Stakeholder engagement and informatics were key to successful program implementation. The EHR must be nimble to address updated recommendations for organisms of concern. Data must be continuously evaluated to measure success of a targeted screening and surveillance program.
