Contact precautions
Contact precautions
Contact precautions (CP) consist in applying the following measures:
- use dedicated equipment (blood pressure cuff, thermometer, and stethoscope);
- put on gown and gloves before entry to the patient’s room;
- change gloves immediately if visibly soiled and after touching or handling surfaces or materials contaminated with faeces;
- remove gown and gloves before exiting the room;
- if cohorting is used, change the gown and gloves and perform hand hygiene after caring for one patient and before providing care for the next patient;
- routinely check available supplies for contact precautions to ensure that adequate selection and amounts are readily available.
There is no study focused on the use of surgical masks as a component of CP in the management of patients with respiratory colonization or infection due to MDR-Gram-negative bacteria. A few papers reported outbreaks due to MDR-A. baumannii added masks on the top of CP in the ICU settings with favourable results. However, the low quality of evidence and the heterogeneity of case-mix of patients do not support generalizing this intervention [1].
In the SHEA guideline for preventing nosocomial transmission of MDR S. aureus and Enterococcus it was recommended to wear masks as part of isolation precautions when entering the room of a patient colonized or infected with MRSA to decrease nasal acquisition by HCWs. However this issue has not been studied adequately [2].
