[Efficacy of control measures to prevent MRSA transmission in health institutions. An up-dated view]

[Ethical aspects of specific precautions programs in patients infected or colonised by multidrug-resistant microorganisms in a hospital setting]

The approach to public health, patient safety and quality of care has led to analysing health situations or problems from a population perspective, in a wide way and giving priority to factors that can normally be left in the background from a clinical point of view. For years, the problem of the use and abuse of antimicrobials, the increase and diffusion of microorganisms resistant to them, cross-transmission, and healthcare related infections have been prioritised both nationally and internationally. To combat these problems, various strategies are being developed and put into practice, from the policies of rational use and optimization of antimicrobials, surveillance, and control of infections related to health care, to training information and awareness strategies. One of the pillars of surveillance and control is the correct application of standard and specific precautions, which within the framework of these comprehensive programs aim to control the transmission of microorganisms of special microbiological and/or epidemiological interest through a series of measures. In hospitals, the application of these precautions (single room, barrier measures, restrictions on access to rooms, waste management…) in patients infected or colonised by these microorganisms can have different repercussions, both for patients and the professionals that attend them, and it is considered pertinent that the protocols and/or programs of specific precautions explicitly include the analysis of the ethical aspects in their preparation, implementation, and monitoring.
