This is an interventional multicenter prospective noninferiority non-randomized double-blind controlled before and after study.
The aim of this study is to demonstrate that standard precautions alone are not inferior to contact precautions by comparing the incidence density of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae acquired in geriatric units before and after discontinuing contact precautions.
Adult patient (> 65 years old)
Patient hospitalized in geriatrics during the study period
Free and informed consent obtained from the patient (or his trusted person or legal representative) within 48 hours of its admission at the geriatric unit
Patient affiliated to a social security scheme
Patient requiring contact precaution for an indication other than ESBL during the patient stay (COVID-19, classical PCC excluding EBLSE, Clostridium difficile PCC, scabies PCC and BHRe PCC)
Patient's stay period less than 4 days
Crossover
Discontinuation of contact precautions for ESBLE
Other interventionDiscontinuation of contact precaution : only standard precaution are implemented for any patient carrying (infected or colonized) ESBLE
Incidence density of acquired ESBLE
Incidence density of acquired ESBLE in geriatric unit for 1000 days of hospitalization is calculated by dividing the number of acquired ESBLE by the number of days of patients' hospitalization multiplied by 1000 Acquisition of ESBLE is defined by a positive sample in patient on discharge day with a negative sample on admission in geriatric unit A positive sample is defined by the presence of at least one ESBLE on a clinical (infection) or screening (colonization) sample. The hospitalisation number is calculated as the cumulative length of stay of all patients at risk (= negative on admission).
Incidence density of acquired ESBLE by species during 6 month period
Incidence density of acquired ESBLE in geriatric unit by species (E. coli versus non-E. coli) for 1000 days of hospitalization. This is calculated by dividing the number of acquired ESBLE by species by the number of days of patients' hospitalization multiplied by 1000. Acquisition of ESBLE is defined by a positive sample in patient on discharge day with a negative sample on admission in geriatric unit A positive sample is defined by the presence of at least one ESBLE on a clinical (infection) or screening (colonization) sample. The hospitalisation number is calculated as the cumulative length of stay of all patients at risk (= negative on admission).
The rate of compliance with hand hygiene in health care providers
The evaluation of the compliance with hygiene measures is calculated in health care providers by dividing the number of hand hygiene moments carried out by the number of opportunities multiplied by 100, according to the World Health Organization (WHO) methodology
Evaluation of the barriers to alcohol-based hand rub in case of non-compliance in health care providers
The barriers to alcohol-based hand rub are identified in case of non-compliance, using a Pulpe' friction questionnaire (RéPIAS) where professionals are interviewed about their practices in terms of hand hygiene. For each situation, the professional is also asked how important it is for him to perform hand hygiene in each situation listed above, with a slider to be positioned between 0 (not at all important; worse outcome) and 10 (the most important; better outcome).
The rate of compliance with personal protective equipment
The rate of compliance with the wearing and removal of personal protective equipment throughout patient care, is observed during care related to the management of excreta (changing, putting on or removing a dish basin, use of a basin washer-disinfector). The rate is calculated by dividing the number of personal protective equipment good caring practices by the number of opportunities multiplied by 100.
