Outbreaks of Nontuberculous Mycobacteria Infections Highlight Importance of Maintaining and Monitoring Dental Waterlines (Emergency Preparedness and Response)

The Centers for Disease Control and Prevention (CDC) is issuing this Health Alert Network (HAN) Health Advisory to emphasize the importance of following existing recommendations for maintaining and monitoring dental waterlines. Multiple outbreaks of nontuberculous Mycobacteria (NTM) infections have occurred in children who received pulpotomies in pediatric dental clinics where the dental treatment water contained high levels of bacteria. CDC provides guidelines on infection control in dental settings which contain recommendations to treat dental unit waterlines and monitor water quality. Dental providers should be familiar with these recommendations on how to properly maintain and monitor their dental equipment to ensure that dental treatment water is safe for patient care.

Clean clothes or dirty clothes? Outbreak investigation of carbapenem-resistant Acinetobacter baumannii related to laundry contamination through multilocus sequence typing (MLST) (Infection Control & Hospital Epidemiology)

This article investigates the source in an outbreak of carbapenem-resistant Acinetobacter baumannii (CRA) in a general hospital due to contamination of a laundry evaporative cooler and the laundry environment using multilocus sequence typing (MLST). MLST confirmed that contamination of the laundry evaporative cooler and surrounding environment caused a polyclonal CRA hospital outbreak. Hospital laundry is an important area for infection control and outbreak investigations of CRA.

States and Territories Strengthening Infection Prevention and Control Policies (ASTHO)

Every year, millions of patients acquire healthcare-associated infections (HAIs) while being treated for other health issues. While largely preventable, HAIs are the most common complication of hospital care and a leading cause of death in the United States. In response to this ongoing issue, states have proposed legislation to strengthen and sustain infection prevention capacity, implement requirements for data tracking and reporting through national surveillance systems, and prioritize antimicrobial stewardship. Discover some of these initiatives in this week’s Health Policy Update.

Mycobacterium chimaera infections among cardiothoracic surgery patients associated with heater-cooler devices—Kansas and California, 2019 (Infection Control & Hospital Epidemiology)

This article describes two recent outbreaks of Mycobacteria chimaera associated with cardiac bypass surgery. Infections in both outbreaks were caused by the same strain of M. chimaera identified previously as part of a large international outbreak involving Sorin 3T heater cooler devices. This investigation demonstrated ongoing problems with these devices and highlighted the ongoing need for attention to mitigation strategies.

Dialysis Water Supply Faucet as Reservoir for Carbapenemase-Producing Pseudomonas aeruginosa (Emerging Infectious Diseases)

During June 2017–November 2019, a total 36 patients with carbapenem-resistant Pseudomonas aeruginosa harboring Verona-integron–encoded metallo-β-lactamase were identified in a city in western Texas, USA. A faucet contaminated with the organism, identified through environmental sampling, in a specialty care room was the likely source for infection in a subset of patients.

Interhospital outbreak of Burkholderia cepacia complex ventilator-associated pneumonia (VAP) caused by contaminated mouthwash in coronavirus disease 2019 (COVID-19) patients (Infection Control & Hospital Epidemiology)

In this article, an inter-hospital outbreak of Burkholderia cepacia complex VAP caused by contaminated chlorhexidine-based mouthwash in COVID-19 patients was investigated. The ability of B. cepacia complex to remain viable in chlorhexidine appears to result from a combination of efflux pump activity, biofilm formation, and cell-wall impermeability. Effective surveillance with practical monitoring by a multidisciplinary team and rapid implementation of outbreak control are even more necessary in mixed ICUs and COVID-19 ICUs. The authors suggested that national regulatory authorities establish protocols for the detection of B. cepacia complex in chlorhexidine-based products, ensuring microbiological quality of the finished product in addition to patient safety, so that similar outbreaks can be prevented.
