This problem is especially relevant in critical care units, where the number of isolates of multiresistant species grow each year<a class="elsevierStyleCrossRef" href="#bib0070"><span class="elsevierStyleSup">1</span></a> reducing the number of alternatives available to treat serious infectious diseases such as sepsis, meningitis or nosocomial pneumonia. Moreover, despite promises and efforts to create new antimicrobials, currently there are little effective developments in the pharmaceutical market.</p><p id="par0010" class="elsevierStylePara elsevierViewall">The spread of multidrug-resistant microorganisms (MDRM) is due to the failure of the measures to prevent cross-transmission but also to the continuous genesis of new resistances. It has been repeatedly shown that the generation of resistance is closely related to exposure to antimicrobials.<a class="elsevierStyleCrossRef" href="#bib0075"><span class="elsevierStyleSup">2</span></a> In this sense, what is most striking is that even 30–50% of prescriptions of antibiotics may be unnecessary.<a class="elsevierStyleCrossRef" href="#bib0080"><span class="elsevierStyleSup">3</span></a></p><p id="par0015" class="elsevierStylePara elsevierViewall">All this has sponsored the development of so-called Antimicrobial Stewardship Programs (ASP) (<span class="elsevierStyleItalic">Programas de Optimización de Antimicrobianos</span> (PROA) in Spanish). These programs include a set of activities intended to optimize the antimicrobial treatment, ensuring the best clinical outcome for the patient but avoiding where possible the development of antimicrobial resistance. The latter objective is largely based on the elimination of all those unfair treatments and on the replacement of broad-spectrum drugs when possible. This type of programs is being implemented in hospitals around the world, proving to be a useful tool in reducing the consumption of antimicrobials and the reduction of bacterial resistance. However, its implementation in critical care units has an added difficulty because of several factors such as patient severity, high MDRM prevalence and pharmacokinetic–pharmacodynamic particularities. However, several works in critical patients have shown the success of the ASP. Examples are the results obtained by Elligsen et al. who achieved a 23% reduction in consumption of antimicrobials and also succeeded an improvement in sensitivity to meropenem.<a class="elsevierStyleCrossRef" href="#bib0085"><span class="elsevierStyleSup">4</span></a> Also noteworthy is the work of Rimaway et al., who, in addition to a reduction in broad-spectrum antibiotics consumption, achieved a diminution in the days of mechanical ventilation and length of stay in the unit.<a class="elsevierStyleCrossRef" href="#bib0090"><span class="elsevierStyleSup">5</span></a> Other studies published in critically ill patients have shown a significant reduction in the use of antimicrobials.</p><p id="par0020" class="elsevierStylePara elsevierViewall">Nevertheless, we do not yet have sufficient scientific evidence to show a positive impact of ASP on the evolution of critically patients and their ecological environment. In fact, in a recent review Mertz et al. underscore this fact by the low methodological quality of the studies published to date.<a class="elsevierStyleCrossRef" href="#bib0095"><span class="elsevierStyleSup">6</span></a> We should note the great difficulty of achieving an effect on hospital stay or mortality due to the multitude of factors that influence the prognosis of critically ill patients. Furthermore, an ASP applied exclusively in the critical care unit could hardly have an effect on the occurrence of bacterial resistance due to the continuous movement of patients with the rest of the hospital. However, given the impact of these programs on antimicrobial consumption and the relationship between antibiotic use and resistance, ASP should be implemented in all critical care units.</p><p id="par0025" class="elsevierStylePara elsevierViewall">ASP format may be different but should be directed to the early stages of antibiotic treatment, should include joint assessment between the pharmacist and the medical care and should conclude with a feedback to the doctor who prescribed the treatment. ASP in ICUs should be led by a specialist in hospital pharmacy in tandem with an intensivist specially dedicated to the field of infection, but must have the support of other specialties such as microbiology and infectious as well as a clear institutional support.<a class="elsevierStyleCrossRef" href="#bib0100"><span class="elsevierStyleSup">7</span></a> Factors that should be evaluated include drug de-escalation to a lower therapeutic spectrum, duration of treatment, pharmacokinetic–pharmacodynamics characteristics and possible interactions (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). By feedback to the prescriber the ASP will also achieve a progressive educational effect.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><span id="sec0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0005">Antimicrobial de-escalation</span><p id="par0030" class="elsevierStylePara elsevierViewall">In much of the infectious processes the antimicrobial spectrum of the initially chosen drugs can be safely reduced following MDRM rule out in the microbiological analysis. This strategy has proven to be safe for patient outcome.<a class="elsevierStyleCrossRef" href="#bib0105"><span class="elsevierStyleSup">8</span></a> In fact, broad-spectrum antimicrobial agents should be reserved for patients with risk factors for MDRM infection (empirical treatment) or before the isolation of a MDRM in clinically representative samples (targeted therapy).</p><p id="par0035" class="elsevierStylePara elsevierViewall">Antimicrobials may also be de-escalated in terms of its number. The combination of antibiotics is one strategy that increases the likelihood of achieving an appropriate empirical treatment. However, once an etiologic diagnosis has been achieved, the combination should be restricted to those cases where the characteristics of the host, the infection, the drug or the microorganism make unlikely to achieve the pharmacokinetic–pharmacodynamic target. An example of this situation could be a severely ill patient with a ventilator-associated pneumonia caused by <span class="elsevierStyleItalic">Pseudomonas aeruginosa</span> susceptible exclusively to colistin and fosfomycin; both drugs have a low lung penetration, <span class="elsevierStyleItalic">P aeruginosa</span> is a typically difficult to eradicate microorganism and the patient is in a critical condition. In this example monotherapy would have little chance of effectiveness and otherwise there would be a high risk of induction of new resistances.</p><p id="par0040" class="elsevierStylePara elsevierViewall">In any case, it must be noted that in most of clinical trials and published meta-analysis, combination therapy has shown little benefit over monotherapy and has proved in many cases an increase in drug toxicity.<a class="elsevierStyleCrossRef" href="#bib0110"><span class="elsevierStyleSup">9</span></a> ASP teams should carefully evaluate the desirability for combined treatment and the duration thereof.</p></span><span id="sec0010" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0010">Antimicrobial treatment duration</span><p id="par0045" class="elsevierStylePara elsevierViewall">Shorten the duration of antimicrobial treatment is one of the main tasks of the ASP team as prolonged treatments are a key element in the genesis of resistance.
