Today’s Outline Burden of multidrug-resistant organisms (MDRO) Challenges with preventing MDRO transmission Define Standard Precautions, Enhanced Barrier Precautions, and ContactPrecautions Identify which residents and activities meet criteria for Enhanced BarrierPrecautions Discuss best practices for implementing Enhanced Barrier Precautions

Threat of Antibiotic Resistance (AR) 2013 CDC Antibiotic Resistance Threats in the UnitedStates– Estimated more than 2 million antibiotic-resistant infectionsand at least 23,000 deaths in US hospitals each year Infections from antibiotic resistant organisms are morecostly and difficult to treat Capacity to detect new antibiotic resistance is constantlyexpandingAntibiotic Resistance (AR) Biggest Threats and reats.html)

Carbapenemase-Producing Organisms (CPOs):Emerging Resistance Threat Produce enzymes that breakdown carbapenems Carry resistance genes on mobile genetic elements, called plasmids, that can be easilyspread Cause invasive infections associated with high mortality rates due to challengesfinding effective antibiotic treatment Emerging throughout the United States and around the globe

Carbapenemases found in CPOs Multiple different mechanisms can cause high level resistance– Examples of Carbapenemase-producing genes found in CRE (CP-CRE) KPC - Klebsiella pneumoniae carbapenemase (most common in U.S.) NDM – New Delhi Metallo-β-lactamase VIM – Verona Integron-encoded Metallo- β -lactamase OXA – Oxacillinase-48-type carbapenemases IMP – Imipenemase Metallo- β –lactamase These genes have been reported in Enterobacteriaceae, Pseudomonasaeruginosa and Acinetobacter baumannii Public health laboratories offer carbapenemase testing

Candida auris Emerging fungal pathogen Tends to be drug-resistant Colonized individuals have risk of invasiveinfection– 5-10% develop C. auris bloodstreaminfection within a year Yeast that spreads easily in healthcare settings,similar to resistant bacteria

Challenges with Detection of MDROs Clinical cultures underestimate trueprevalence of MDROs Most centers are not performing activesurveillance to identify asymptomatic,colonized residents– Contribute to the reservoir fortransmission Inadequate communication about individualMDRO history or risk factors betweenhealthcare facilities during care transitions

Containment StrategySystematic public health response to slow the spread of emerging ARDetectionInfection ControlContact ScreeningOften responding to asingle caseOnsite assessment usingstandardized toolsAvailable through ARLNRegular infection control assessments and screening(point prevalence surveys) until transmission stops.

AR Containment Response Experience in Post-acute CareReview of 113 CDC supported responses to emerging AR pathogens from Jan2017-Dec 2018 Over 60% (72) involved post-acute care facilities (i.e., long-term acute carehospitals, nursing homes, inpatient rehabilitation facilities)– 70% of these post-acute care responses occurred in high-acuity facilities,LTACHs or nursing homes with ventilator units Although ventilator services in nursing homes remain relatively rare, ( 5%),25% of AR containment responses involved nursing homes with this capability

Common Infection Control Challenges Identified duringAR Containment Responses Gaps in adherence to hand hygiene, limited access to alcohol-based handrubs inside and outside of resident rooms Limited access to personal protective equipment (PPE) and minimal use ofContact Precautions Improper product selection, use and frequency to reduce environmentalsurface contamination within shared rooms Inadequate cleaning/disinfection of equipment shared between residents Incomplete communication of MDRO history or risk factors during facilitytransfers

Focusing only on residents with active infection failsto address the continued risk of transmission fromresidents with MDRO colonization,which can persist for long periods of time (e.g.,months), and result in the silent spread of MDROs.

Enhanced Barrier Precautions (EBP):Guidance for Nursing Homes to Prevent MDRO SpreadImplementation of PPE in Nursing Homes to Prevent Spread of Novel or Targeted ng-Homes.html

“Enhanced Barrier Precautions expand theuse of PPE beyond situations in which exposure toblood and body fluids is anticipatedand refer to the use of gown and gloves duringhigh-contact resident care activities that provideopportunities for transfer of MDROs to staff handsand clothing.”

High-contact Resident Care Activities Dressing Bathing/showering Transferring Providing hygiene Changing linens Changing briefs or assisting with toileting Device care or use of a device: central line, urinary catheter, feeding tube,tracheostomy/ventilator Wound care: any skin opening requiring a dressing

Infect Control Hosp Epidemiol (2018), 39,1425-1430

Enhanced Barrier Precautions should be usedfor all residents with any of the following: Infection or colonization with a novel or targeted MDRO (as of July 2019)defined as:̶ Pan-resistant organisms,̶ Carbapenemase-producing Enterobacteriaceae,̶ Carbapenemase-producing Pseudomonas spp.,̶ Carbapenemase-producing Acinetobacter baumanii,̶ Candida auris Wounds and/or indwelling medical devices (e.g. central line, urinary catheter,feeding tube, tracheostomy/ventilator) regardless of MDRO colonizationstatus residing in an at-risk area When Contact Precautions do not apply

Contact Precautions should be used: All residents infected or colonized with a novel or targeted multidrugresistant organism in specific situations:̶ Presence of acute diarrhea, draining wounds or other sites of secretions orexcretions that are unable to be kept covered or contained̶ On units or in facilities where ongoing transmission is documented orsuspected For infections (e.g., C. difficile, norovirus, scabies) and other conditionswhere Contact Precautions is recommended̶ See Appendix A – Type and duration of Precautions Recommended forSelected Infections and Conditions of the CDC Guideline for IsolationPrecautions

Why was the EBP Guidance Needed for Containment?Focusing only on residents with active infection fails to address the continued riskof transmission from residents with MDRO colonization, which can persist for longperiods of time (e.g., months) and result in the silent spread of MDROS. Contact screening detects additionalcolonized residents not previouslyrecognized Facilities needed an approach togown/glove use that was less restrictivethan Contact Precautions and could besustained for prolonged period of time EBP also addresses care of residents at riskfor acquiring colonizationAs of July 2019, Novel or TargetedMDROs are defined as: Pan-resistant organisms, Carbapenemase-producingEnterobacteriaceae, Carbapenemase-producingPseudomonas spp., Carbapenemase-producingAcinetobacter baumannii, and Candida auris

Includes restriction of movement andparticipation in group activities within thefacility

Implementing Enhanced Barrier Precautionsor Contact Precautions

Post Clear Signage outside of the Resident Room Indicate type of Precautions andrequired PPE For EBP, indicate high-contact residentcare activities

The Set-Up: Personal Protective Equipment PPE, including gowns and gloves,should be available immediatelyoutside of resident room Plan for restocking Position a trash can insideresident room and near exit fordiscarding PPE

The Set-Up: Hand Hygiene Ensure access to alcohol-basedhand rub at every resident room Ideally located both inside andoutside of room Make performing hand hygieneeasy!

Cleaning & Disinfection of Shared Equipment Ensure access to cleaningsupplies/wipes Contact Precautions: dedicatedequipment

Auditing Practices and Education Incorporate periodic monitoring andassessment of adherence to determine needfor additional training and education

Ongoing Activities and Future Steps Development of additional resources to promote EBP (e.g., FAQs) Collaborating with nursing home organizations to evaluate staff education andtraining, PPE utilization, and other resource needs for successfulimplementation Will include assessments of acceptability and costs Funding projects to evaluate strategies to prevent MDRO transmission Efficacy of targeted gown/glove use; role of Chlorhexidine bathing anddecolonization; Impact of improved environmental cleaning/disinfection Establishing a Working Group to convene nursing home, academic and publichealth partners to discuss broader implementation of EBP outside of acontainment response
