Background

C. auris has been identified from > 1600 US patients. Risk factors include high-acuity post-acute care admissions (e.g., long-term acute care hospitals (LTACHs)), hospitalization abroad, and carbapenemase-producing organism (CPO) colonization. Early detection of C. auris is key to controlling spread. We describe four active surveillance strategies that led to early C. auris identification.

Methods

Based on known risk factors, state health departments used active C. auris surveillance strategies: (1) species identification of yeast from urine cultures from LTACHs, (2) screening patients with a CPO and hospitalization abroad, (3) LTACH C. auris point prevalence surveys (PPS), or (4) admission screening in acute and long-term care settings.

Results

(1)A laboratory in Southern California serving 12 LTACHs began species identification for all Candida from urine cultures, which would have otherwise been discarded because they are assumed to be not clinically significant. Within 5 months, testing of 271 Candida urine isolates identified the region’s first C. auris case, prompting contact tracing and identification of additional cases and facilities. (2) When CPOs were identified in patients with recent hospitalizations outside of the United States, the Maryland Department of Health screened patients for C.auris colonization. Of four screened, one, who received care in Kenya, was C. auris colonized. (3) The Indiana State Department of Health implemented monthly PPS at an LTACH that frequently admits patients transferred from a high prevalence area. Of 38 patients screened, two were colonized. (4) The Connecticut Department of Public Health offers C. auris admission screening for patients who received inpatient care in high prevalence areas; of 12 screened, one C. auris colonized patient was found. Infection control assessments and implementation of infection control measures followed each detection.

Conclusion

Early detection of C. auris is important but is impacted by infrequent yeast species identification and a reservoir of asymptomatic colonized patients. Healthcare facilities and public health jurisdictions can consider adopting one or more of these strategies based on epidemiology and resource availability.
