Carbapenem-resistant Enterobacterales-Kentucky, 2013-2020: Challenges and Successes.

INTRODUCTION

Carbapenem-resistant Enterobacterales (CRE) are considered urgent, antibiotic-resistant threats in the U.S. and are of global concern. Active collaboration between public health authorities and healthcare facilities and providers will be necessary to prevent and contain these organisms.

PURPOSE

To describe the epidemiology of CRE in Kentucky and to discuss challenges and successes with building and sustaining an effective prevention and containment program.

METHODS

Retrospective descriptive summary of CRE isolates reported by healthcare providers, facilities, and laboratories in Kentucky from 2013 through 2020. Data available from case reporting forms and laboratory testing are summarized.

RESULTS

From 2013 through 2020, 1805 CRE were reported from 1666 individuals; median age was 66 years and 44% were male. Although most reports were from hospitalized individuals, nearly one-third were from individuals not hospitalized in acute-care hospital settings. The number of reports generally increased over time, with 111 CRE isolates in 2013 and 477 in 2020. was the most frequently reported CRE. Of the 29% of CRE with identified carbapenemase production (CP-CRE), carbapenemase (KPC) was most common (78%). Surveillance and reporting resulted in identification and active investigation of 11 outbreaks of CP-CRE.

IMPLICATIONS

There are challenges with developing, implementing, and sustaining a consistent, effective response to identifying, preventing, and containing CRE. Ongoing public health and facility resources will be necessary to prevent and contain antibiotic-resistant threats and other concerning organisms.
