Decolonization:
• Bathe with an antiseptic on skin
• Apply antibiotic or antiseptic in the nose, because staph tends to live in the nose
CDC: Decolonization is a key way to prevent Staph aureus infections:
• Helps prevent colonized patient from getting an infection
• Reduces bacterial bioburden and likelihood of transmission so HCPs in contact with colonized patients are less likely to get bacteria on their skin and clothes and pass it on to the next person
“Decolonization prevents spread of pathogens and prevents the infection in the first place”

• The nose is the primary reservoir for MSSA/MRSA and the most reliable predictor of colonization
• Nasal colonization is the #1 risk factor for subsequent infection
• 80% of MSSA/MRSA BSI and SSI infections are endogenous and traced to the patient’s nasal flora

Objective
To reduce MRSA
transmission and
infection risk posed
by patients who are
MRSA colonized.
Risk Mitigation Strategy – Screen and Isolate
![Page 25: Platform Presentation Final AM 10 30 19 - nozin.com › wp-content › uploads › Platform-Presentatio… · Microsoft PowerPoint - Platform Presentation Final AM 10_30_19 Author:](https://reader034.vdocuments.us/reader034/viewer/2022042403/5f14e88fa95ab753800e8988/html5/thumbnails/25.jpg)
2. Screen high risk patients for MRSA colonization (MRSA surveillance practice)
3. Contact Isolation Precautions (CP) for detected MRSA colonized patients for length of stay
1. Identify patients with high risk of MRSA nasal carriage• Critical care patients (ICU)• ALF/Nursing home residents• Prior history of MRSA• Diabetics, oncology patients, etc.

• Does not prevent colonized patients from touching their nose and contaminating their hands.

Isolation for MRSA Carriers
Detrimental to patients*
• Isolated patients get less care (quality & quantity)
• Isolated patients have worse outcomes
• Isolated patients have lower satisfaction scores
A hindrance to staff**
• Deterrent to frequent patient contact
• “Isolation fatigue”
• Results in lack of compliance with CP
A burden for the facility***
• Does not optimize patient flow
• Reduces throughput – utilization
• High costs of screening and isolation

Arm 1: Screen and Isolate
– Screened all ICU patients and isolated known MRSA (+)
Arm 2: Targeted Decolonization– Screened all ICU patients
– Targeted nasal decolonization/CHG bathing only for known MRSA (+)
Arm 3: Universal Decolonization– No screening
– Universal nasal decolonization/CHG bathing for all ICU patients

Benefits of Universal Decolonization
Universal decolonizationTreat all patients regardless of colonization status
• eliminates MRSA surveillance tests and the associated contact precautions, which interfere with care
• begins on the first ICU day, avoiding the delay in decolonization pending results of screening tests.
• protects patients in the ICU from their own microbiota during a period of heightened vulnerability to infection.
• reduces the environmental pathogen burden, reducing opportunities for patient-to-patient transmission.
• lowers ICU costs—cost-effectiveness studies show cessation of screening, reduced contact precautions, and reduced infections offset product costs, resulting in savings

Antibiotic - Mupirocin (Bactroban®)• Was the only tool for many years – and is still used today
Limitations to consider:
• Selective mechanism of action (gram +)
• 5 day BID course – limited effectiveness until day 3*
• Does not comport with antibiotic stewardship*
• 60% - 93% effective*
• Resistance concerns**

Antibiotic - Mupirocin

Antiseptic – Povidone iodine• Long history as a pre-op and wound antiseptic
• Effective against both gram (+) and (-) organisms
• Comports with antibiotic stewardship
Limitations to consider:
• Nasal application developed for one time, pre-op use only
• 12 hr persistence – requires daily use to prevent recolonization • Cannot be used on patients with renal or hepatic failure, those with
thyroid disfunction nor patients with hyper sensitivities/allergies to iodine• FDA warning notice of potentially severe reactions
Antiseptic - Povidone Iodine

Antiseptic – Ethanol• Long history as a pre-op, wound and skin antiseptic
• Effective against both gram (+) and (-) organisms
• Comports with antibiotic stewardship

Conclusions
1. Nasal carriage poses a substantial infection risk.
2. Limitations of current MRSA risk mitigation programs do not address the primary reservoir – the nose.
3. Universal ICU decolonization strategies replacing screen and isolate and targeted decolonization are feasible, cost effective and widely accepted.
4. Nasal decolonization antiseptics (which overcome the limitations of mupirocin) improve HAI outcomes, quality of care and patient/staff satisfaction.
