# Concise communication title: wide adoption of rapid molecular detection of antimicrobial resistance markers for use with blood cultures: implications for national surveillance of antimicrobial resistance

## TL;DR

This paper examines how US hospitals are adopting fast molecular tests for antibiotic resistance and how this affects national tracking of resistance.

## Contribution

The study provides the first summary of molecular AR testing adoption in US hospitals and its implications for national surveillance.

## Key findings

- Rapid molecular testing for AR is being increasingly adopted by US acute care hospitals.
- The adoption may significantly impact the National Healthcare Safety Network's ability to monitor AR trends.

## Abstract

Rapid molecular testing for antimicrobial resistance (AR) provides an indication of resistance faster than phenotypic antimicrobial susceptibility testing. We summarize the adoption of molecular testing for AR among US acute care hospitals and discuss the potential impact on National Healthcare Safety Network’s surveillance for AR.
