When should you decolonise for MRSA?
when there are ongoing MRSA infections occurring in a well-defined, closely-associated cohort, for example a dormitory, day-care centre or sports club. If there are ongoing infections in a household despite treatment, decolonisation of all household members should be considered, even if some members do not have an active infection.
What is MRSA colonisation?
MRSA colonisationgrowth of MRSA from a body fluid or swab from any body site. The most common site of colonisation is the anterior nares, but MRSA can also be found in other areas such as the axillae, abnormal skin (e.g., eczema, wounds), urine, rectum, and throat.
What are the treatment options for MRSA?
The MRSA strategy of our institution (a 700 bed tertiary hospital in eastern Switzerland) consists of a 5-day regimen of nasal mupirocin ointment, chlorhexidin mouth rinse and whole body wash with didecyldimonium chloride. Systemic antibiotics are usually not added to the regimen.
When are systemic antibiotics indicated in the treatment of MRSA infection?
Systemic antibiotics may be preferred if prior treatment with topical agents has failed or an oropharyngeal or gastrointestinal source of MRSA colonisation is suspected. Substantive changes
How long does it take to decolonize MRSA?
There is no consensus on the optimal duration of systemic antibiotic treatment to eradicate MRSA carriage; regimens of 7–14 days have been used. For mupirocin treatment of nares, treatment for 5–7 days has been effective. If wounds are treated, a duration of 14 days has been suggested [23].
How long is MRSA treatment?
MRSA-active therapy may be modified if there is no clinical response. Treatment for seven to 14 days is recommended, but should be individualized to the patient's clinical response.
What is the MRSA decolonization regimen?
Because MRSA carriage is most common in the nares and on the skin (particularly in sites such as the axilla and groin), MRSA decolonization therapy typically includes intranasal application of an antibiotic or antiseptic, such as mupirocin or povidone-iodine, and topical application of an antiseptic, such as ...
What do MRSA decolonisation treatments involve?
Decolonisation is when topical treatments are used to try and get rid of methicillin resistant staphylococcus aureus (MRSA). It involves the use of an antiseptic body wash and nasal ointment for 5 days. Decolonisation treatment can reduce the risk of recurrent MRSA infections or spreading MRSA to others.
How long do you take vancomycin for MRSA?
aureus bacteremia trial, the duration of MRSA bacteremia for vancomycin-treated and daptomycin-treated patients was similar (9 vs 8 days).
How long is MRSA contagious after starting antibiotics?
As long as a staph infection is active, it is contagious. Most staph infections can be cured with antibiotics, and infections are no longer contagious about 24 to 48 hours after appropriate antibiotic treatment has started.
What is a decolonization protocol?
The Universal ICU Decolonization protocol combines a comprehensive implementation readiness assessment with scientific rationale and training tools for implementation of a universal decolonization strategy to reduce Methicillin-Resistant Staphylococcus aureus (MRSA) and bloodstream infections in adult intensive care ...
How effective is MRSA decolonization?
Decolonization was successful in 54 (87%) of the patients in the intent-to-treat analysis and in 51 (98%) of 52 patients in the on-treatment analysis. Conclusion: This standardized regimen for MRSA decolonization was highly effective in patients who completed the full decolonization treatment course.
How long do you need to leave to MRSA screen the patient after they have completed MRSA suppression therapy?
Begin at least 48 hrs after end of antiseptic and antibiotic therapy. If decolonisation fails, seek advice from the Infection Control Team. What do I do if a patient is discharged from hospital MRSA positive?
How do you decolonize MRSA at home?
MRSA DecolonizationRubbing ointment into each of your nostrils twice a day for 5 days.Taking a shower or bath using a special soap once a day for up to 5 days while you are using the nasal ointment.
What is targeted decolonization?
Background. Both targeted decolonization and universal decolonization of patients in intensive care units (ICUs) are candidate strategies to prevent health care–associated infections, particularly those caused by methicillin-resistant Staphylococcus aureus (MRSA).
How long does it take MRSA to spread?
For most staph infections, including MRSA, the incubation period is often indefinite if the organisms are colonizing (not infecting) an individual (see above). However, the incubation period for MRSA often ranges from one to 10 days if it enters broken skin or damaged mucous membranes.
How long does it take to decolonize your nose?
If your practitioner prescribes decolonization, there are two parts to the treatment: Rubbing ointment into each of your nostrils twice a day for 5 days. Taking a shower or bath using a special soap once a day for up to 5 days while you are using the nasal ointment.
Why is decolonization important?
Decolonization may help reduce the risk of spreading the germs to others and help to avoid future infections. Based on testing and health needs, your practitioner may determine that decolonization is right for you. If your practitioner prescribes decolonization, there are two parts to the treatment:
What is the name of the bacteria that can be removed from your nose?
MRSA Decolonization. Many people have been exposed to a germ called Staphylococcus aureus. These germs can live on your skin and in your nose. Some of these specific germs are resistant to certain antibiotics. They are called Methicillin-resistant Staphylococcus aureus, also known as MRSA. The removal of MRSA is called "decolonization".
How to use ointment for a large tube?
If you have the large tube, you should use a pea-sized amount of ointment inside each nostril each time you apply the ointment. Save the large tube and use it for all your doses.
Where is the most common MRSA?
The incidence of MRSA varies from country to country. The UK, Ireland, and southern Europe (e.g., Spain, Italy, and Greece ) have a high incidence when compared with northern Europe and Scandinavia. The most objective measure of incidence is the percentage of S aureusfound in blood cultures that are resistant to methicillin. Rates may exceed 40% in many countries.
What is the term for eradicating colonization in people without active invasive infection?
MRSA colonisation (eradicating colonisation in people without active invasive infection)
What are the risk factors for MRSA?
Traditional risk factors for MRSA colonisation include prolonged stay in hospital, severe underlying disease, prior antibiotics, exposure to colonised people, and admission to a high-risk unit (critical care, renal unit, etc). MRSA has primarily been a problem associated with exposure to the healthcare system. More recently, MRSA strains have emerged in the community (so-called community-associated MRSA [CA-MRSA] strains) that have no relationship with healthcare-related strains. These strains may colonise and cause infection among young, healthy people.
Does MRSA colonization reduce infection rates?
It has been thought that reduction or elimination of MRSA colonisation might lead to reductions in MRSA infection rates. Different topical and systemic antimicrobial regimens have been tried in various patient populations, with variable outcomes. Given that MRSA infection remains a significant problem in healthcare settings and, now, in the community, it is important to re-examine the evidence for or against the treatment of MRSA-colonised patients.
Is MRSA a carrier?
Methicillin-resistant Staphylococcus aureus(MRSA) carriers are at increased risk for recurrent MRSA infection. Carriers who are found to be colonised with MRSA at multiple body sites or who are found to be persistently colonised with MRSA over time are at greater risk of infection with that bacterium. Furthermore, trauma, surgical incisions, or use of indwelling medical devices in the MRSA carrier may facilitate the introduction of the organism into deeper tissues, leading to MRSA infection.
Is MRSA a gene?
Methicillin-resistant Staphylococcus aureus (MRSA) contains a gene that makes it resistant to methicillin as well as to other beta-lactam antibiotics, including flucloxacillin, cephalosporins, and carbapenems. MRSA can be part of the normal body flora (colonisation), especially in the nose, but it can cause infection. Until recently, MRSA has primarily been a problem associated with exposure to the healthcare system, especially in people with prolonged hospital admissions or underlying disease, or after antibiotic use. In many countries worldwide, a preponderance of S aureus bloodstream isolates are resistant to methicillin.
Is MRSA more virulent than S aureus?
The virulence of MRSA, or its ability to cause death and severe infection, seems to be greater than that of methici llin-susceptible S aureusstrains. A meta-analysis of 31 cohort studies found that mortality associated with MRSA bacteraemia was significantly higher than that of methicillin-susceptible S aureusbacteraemia (mean mortality not reported; OR 1.93, 95% CI 1.54 to 2.42).
Introduction
- Decolonisation is the process of eradicating or reducing asymptomatic carriage of MRSA.
- The nares are the primary site of colonisation. Other sites of colonisation include the nasopharynx, skin (especially skin folds), perineum, axillae and the gastrointestinal tract.
- Decolonisation should only commence once the infection has cleared.

- Decolonisation should only commence once the infection has cleared.
- When an individual has MRSA, contamination of their environment and clothing can occur due to the shedding of skin scales and touching surfaces with contaminated skin or hands.
Indications
- The decision to recommend decolonisation should follow an assessment of the individual (and their close contacts) that includes their willingness and capability to comply with the regimen. Decolonisation is generally recommended when individuals or their household contacts: 1. have recurrent MRSA or staphylococcal-like infections 2. are at increased risk of infection due to othe…

Factors Contributing to Decolonisation Failure
- Decolonisation is less likely to be successful if the individual has throat carriage, chronic or open wounds or permanent indwelling devices in situ.
- There is the potential for failure and/or re-colonisation if there is non-compliance with the requirements for personal hygiene and environmental cleanliness.
- Decolonisation should not be commenced on people with scabies or active exfoliative skin c…
