Patients admitted to our ICU from October 2013 to September 2014 formed the control group. The intervention period was from October 2014 to September 2015. Antimicrobial consumption, costs, MDRM prevalence, nosocomial infection incidence (including urinary tract infection, ventilation associated pneumonia and catheter-related infection), ICU mortality, and ICU length of stay were compared between periods.</p><p id="par0025" class="elsevierStylePara elsevierViewall">The study was performed in a tertiary academic teaching hospital with 984 beds. The medical ICU of the hospital has 24 beds, with a mean of 1592 admissions annually during the last five years. Our ICU nosocomial infection control programme includes the performance of surveillance cultures (oral and rectal swabs and tracheobronchial aspirates in ventilated patients) on ICU admission, and weekly to detect MDRM colonisation, as well as a daily meeting with microbiologists, infectious diseases physicians and staff members of the infection control department (to assess the situation of nosocomial infection, prevalence of MDRM, and design appropriate interventions). In those patients with MDRM colonisation/infection, special surveillance and control measures were taken to prevent microbial dissemination.</p><p id="par0030" class="elsevierStylePara elsevierViewall">In October 2014 prospective audit and feedback antimicrobial stewardship programme strategies were put into practice. The AMS team included an intensivist physician specialising in infectious diseases and a pharmacist. The pharmacist reviewed every patient with antimicrobial prescriptions daily, and those who met previously established alarm criteria were discussed with the intensivist in a 20<span class="elsevierStyleHsp" style=""></span>min dedicated meeting. Alarm criteria were the following: (1) antimicrobial prescription of carbapenems, linezolid, tigecycline, daptomycin, colistin and antifungal agents (including azoles, equinocandines and amphotericin B); (2) Treatment durations exceeding the recommendations established in the local treatment guidelines for each type of infection (3) Dosage not considered appropriate to patient condition; (4) Treatment adjustment (including de-escalation) to microbiological results, and (5) Relevant interactions and adverse events associated with antimicrobial therapy.</p><p id="par0035" class="elsevierStylePara elsevierViewall">If any antimicrobial treatment modification was recommended in the AMS meeting, a face-to-face interview was held between AMS team and the attending physician. In the end, the prescribing physician would decide whether or not to accept the recommendation. Patient data and actions taken by the AMS team were entered into a database. The degree of acceptance of the recommendation was recorded by reviewing the patient's prescription the day after the intervention. Monthly indicators of AMS team operations and antimicrobial consumption were obtained.</p><p id="par0040" class="elsevierStylePara elsevierViewall">Demographic and clinical data, cause of ICU admission, APACHE-II score calculated during the first 24<span class="elsevierStyleHsp" style=""></span>h of admission, relevant findings during ICU stay, antimicrobial and non-antimicrobial treatments, and outcome data were recorded.

Antimicrobials cost was obtained from the stock management system and dispensing software used in the hospital. Total cost of antimicrobials consumption was calculated based on the selling price (PVL) at the beginning of the pre-intervention period (September 2013).<a class="elsevierStyleCrossRef" href="#bib0280"><span class="elsevierStyleSup">17</span></a></p><p id="par0045" class="elsevierStylePara elsevierViewall">Time series analysis was used to evaluate the trends in ICU and total hospital antimicrobial consumption.

In fact, it is known that antimicrobials are used widely in the ICUs.<a class="elsevierStyleCrossRef" href="#bib0290"><span class="elsevierStyleSup">19</span></a> However, it is well-known that antimicrobial overuse can promote the emergence of multidrug-resistant bacteria in these units.<a class="elsevierStyleCrossRef" href="#bib0295"><span class="elsevierStyleSup">20</span></a> Recent reports suggest that drug development will not adequately address the problem of antibiotic resistance among common bacterial pathogens.<a class="elsevierStyleCrossRef" href="#bib0300"><span class="elsevierStyleSup">21</span></a> Several reasons for the current situation have been proposed, including difficulties in identifying new bacterial targets, or even the possibility that the majority of targets amenable to antibacterial activity have already been identified.<a class="elsevierStyleCrossRef" href="#bib0305"><span class="elsevierStyleSup">22</span></a> The lack of promotion of public and private research in discovery and development of new antimicrobial agents also contributes to this situation.

Elliggsen et al. achieved a clear decrease in the consumption of antibiotics, and also a decrease in resistances to the monitored antibiotics, as well as a decrease in <span class="elsevierStyleItalic">C. difficile</span> infections. However, although this is an extremely careful study, they only intervened on specific antibiotics (third-generation cephalosporins, β-lactam and β-lactamase inhibitor combinations, fluoroquinolones, and vancomycin) and there was no intervention on the use of antifungal drugs.<a class="elsevierStyleCrossRef" href="#bib0355"><span class="elsevierStyleSup">32</span></a> Currently, at least in our area, AMS programmes should also include the most controversial antimicrobials such as tigecycline, linezolid, daptomycin, or antifungals drugs. Taggart et al. described a one-year experience in a medical and a surgical unit.<a class="elsevierStyleCrossRef" href="#bib0360"><span class="elsevierStyleSup">33</span></a> However, in this study antimicrobial reduction was limited to anti-psuedomonal antibiotics. No differences in resistance patterns, length of stay and mortality rate was observed. As the authors concluded, we agree that a longer follow up period is required to appreciate changes in ICU ecology. Other experiences described in critical care units have found reduction in antimicrobial use after AMS implementation.<a class="elsevierStyleCrossRefs" href="#bib0365"><span class="elsevierStyleSup">34–36</span></a> However, the description of the clinical impact of these interventions, as well as its effect on the infection and colonisation by multiresistant strains is highly variable, making difficult to draw firm conclusions.</p><p id="par0110" class="elsevierStylePara elsevierViewall">In our study, we found that ICU antimicrobial consumption significantly decreased with AMS programme implementation. Antimicrobial consumption dropped from 380.6 to 295.2 DDD/100 patient-days, which was a decrease of 22.4%. Of great significance is the high percentage of acceptance among members of the critical care team, which was even higher than that achieved in the study previously mentioned (82% of acceptance).<a class="elsevierStyleCrossRef" href="#bib0350"><span class="elsevierStyleSup">31</span></a> This could be justified by the direct participation of a member of the team and the continuity of the pharmacist involved in the AMS programme. The importance of an intensivist involved in this type of programmes depends not only on the selection and duration of the antibiotic treatment in a critical situation, but also on the knowledge of all those situations that require a dose adjustment in the antimicrobial dosage, as well as those interventions beyond antibiotic management that can prevent infections and improve patients’ prognosis and shorten the duration of their treatment,<a class="elsevierStyleCrossRef" href="#bib0380"><span class="elsevierStyleSup">37</span></a> including a proper management of the airway, maintenance and early catheter withdrawal, and so on.</p><p id="par0115" class="elsevierStylePara elsevierViewall">After AMS implementation, the effect on carbapenem, tigecycline and colistin consumption did not reach a statistically significant reduction. These results could be due to the coincidence during the study of an ESBL <span class="elsevierStyleItalic">K. pneumoniae</span> outbreak in our ICU, only susceptible to carbapenems, amikacin, colistin and tigecycline. Therefore, our results could have been affected by this specific epidemiological context. It should be notice that de-escalation has been one of the main interventions recommended by our AMS team. Antimicrobial de-escalation in critically ill patients has been associated not only with a reduction in antibiotic resistance, but also with an improvement in clinical evolution of patients.<a class="elsevierStyleCrossRef" href="#bib0385"><span class="elsevierStyleSup">38</span></a> Even some broad-spectrum antimicrobials could not be avoided in critically ill patients and/or ICUs with high prevalence of MDRM, treatment duration and de-escalation could be guided by AMS programmes in order to reduce resistance selection.</p><p id="par0120" class="elsevierStylePara elsevierViewall">After one year of intervention, we did not achieve a global significant decrease of total MDRM colonisation rate. Although AMS interventions have been associated with a reduction in the emergence of MDRM, a longer follow up period may be required to appreciate changes in ICU ecology.<a class="elsevierStyleCrossRef" href="#bib0390"><span class="elsevierStyleSup">39</span></a> On the other hand, it should be considered that during the intervention period, there was an ESBL <span class="elsevierStyleItalic">K. pneumonia</span> outbreak in the unit that has had a great impact on the number of patients colonised. Our results show that AMS interventions must be carried out jointly with an increase in measures to prevent environmental bacterial transmission in order to reduce the spread of multiresistant pathogens.</p><p id="par0125" class="elsevierStylePara elsevierViewall">Total antimicrobial consumption in the hospital did not change during the study period. This phenomenon is of great relevance, given that an important part of patients admitted to the ICU come from other hospital units, and antibiotic resistance generated in other wards may end up in the ICU. This idea reinforces the need for a global AMS all over the hospital to ensure the rational use of antibiotics and to prevent antibiotic resistance. Nevertheless, our AMS programme efficacy (in terms of antimicrobial consumption, antimicrobial costs, and decrease in other MDRM), even in the presence of an ESBL <span class="elsevierStyleItalic">K. pneumoniae</span> outbreak, reinforces the utility of this kind of intervention in the critical care setting.</p><p id="par0130" class="elsevierStylePara elsevierViewall">Our study has several limitations. We described an intervention study in a single-centre. Intervention safety was assured by the lack of effect on ICU nosocomial infection rates, length of stay, and mortality. However, long-term effects of AMS programmes should be evaluated in order to assess the real impact of this multidisciplinary intervention on patient mortality and in bacterial resistance. Moreover, the existence of an ESBL <span class="elsevierStyleItalic">K. pneumoniae</span> outbreak during the study period could have affected our results, but in any case this would give more strength to the positive ones. On the other hand, given the lack of information available during the prior to the AMS implementation, we have not been able to evaluate two of the indicators recommended to assess the appropriateness of antimicrobial treatment<a class="elsevierStyleCrossRef" href="#bib0270"><span class="elsevierStyleSup">15</span></a>: Days of treatment (DOT) and percentage of appropriate empirical treatment. However, it is important to highlight the difficulties in evaluating this last indicator in the critically ill patient, given the high number of patients with negative microbiological cultures, as well as the possible confusion generated by colonisation samples. Moreover, despite the fact that DDDs have the limitation of being dependent on the dose of antimicrobial prescribed and therefore its value could be modified in the most severe patients, since the characteristics of the patients have not varied significantly between both periods, we consider that the comparison of DDDs value between both periods reflects the real decrease in antimicrobial consumption after AMS implementation.</p><p id="par0135" class="elsevierStylePara elsevierViewall">Antibiotic resistance has become a major clinical and public health problem. Our results further support the implementation of an AMS programme in critical care units, and reinforces the efficacy of an audit and feedback design, lead by an intensivist expert in the management of infections in the critically ill patients. These interventions require continuous tracking, monitoring and assessment. Antimicrobial consumption and outcome indicators should be used to provide feedback to prescribers, and even to the hospital management team.</p><p id="par0140" class="elsevierStylePara elsevierViewall">In conclusion, the implementation of antimicrobial stewardship strategies in an audit and feedback design significantly reduced antimicrobial use in a relatively short period. Long-term effects of these programmes over the local microbial resistance and patient outcomes should be evaluated in future studies.</p></span><span id="sec0025" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0115">Funding</span><p id="par0145" class="elsevierStylePara elsevierViewall">No funding has been received for this article.</p></span><span id="sec0030" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0120">Authors’ contributions</span><p id="par0150" class="elsevierStylePara elsevierViewall">JR participated in the design of the study, data collection and performed the statistical analysis.
