Does high adherence to contact precautions lead to low in-hospital transmission of multi-drug-resistant micro-organisms in the endemic setting?
Conclusion: High adherence coupled with continuous monitoring of CPs correlated with a very low in-hospital transmission rate. These results indicate that CPs are highly effective if routine monitoring of adherence is implemented. (Source: Current Awareness Service for Health (CASH))

Optimal trough concentration of teicoplanin for the treatment of methicillinresistant Staphylococcus aureus infection: A systematic review and metaanalysis
What is known and objective: It has been recommended that the trough concentration (Cmin) of teicoplanin should be maintained at ≥20 μg/ml for difficult‐to‐treat complicated infections caused by methicillin‐resistant Staphylococcus aureus (MRSA). Conversely, Cmin of teicoplanin of at least 10 μg/ml is required for non‐complicated MRSA infections. Considering the low incidence of nephrotoxicity for teicoplanin, Cmi n = 15–30 μg/ml has been suggested for most MRSA infections. Thus, we assessed the clinical efficacy and adverse effects of teicoplanin at this target Cmin. Methods: We searched electron...
