好像是没有明确的要求的，这个是美国CDC相关的答复：
There is currently not enough information for CDC to make a general recommendation on when isolation can be discontinued for patients colonized or infected with CRE. CRE colonization can be prolonged (> 6 months). Across multiple studies, predictors of prolonged CRE carriage have been found to include:
exposure to antibiotics
presence of an invasive device
higher Charlson’s co-morbidity scores
number of hospital admissions
admission from another facility
admission from or discharge to a long-term care facility [Schechner et al., 2011; Feldman et al., 2013; Zimmerman et al., 2013]
Presence of these predictors should be considered when deciding whether to discontinue Contact Precautions.
If considering discontinuing Contact Precautions based on the results of surveillance cultures, it is appropriate to wait for at least 3 to 6 months since last positive culture or screen. The decision to discontinue Contact Precautions for an individual with a history of colonization or infection with CRE should be made in consultation with public health. In general, failure to identify CRE from at least two sets of screening cultures are the minimum criteria that should be met before an episode of colonization is considered resolved. Additionally, retesting of the site(s) that were positive initially from clinical cultures is usually indicated, particularly non-sterile sites such as a wound or urine. |
