Antimicrobial Stewardship: DEFINITIONS
An activity that optimizes antimicrobial management andincludes selection, dosing, route and duration ofantimicrobial therapy.
A marriage of infection control (Epidemiologist), and antimicrobialmanagement (Infectious Diseases specialist) finalized to share the principlesof the optimized treatment between the bench to bed side point of viewand the hospital-wide vision

6.There are 2 core strategies, both proactive, that provide the foundation for anantimicrobial stewardship program. These strategies are not mutually exclusive.
A. Prospective audit with intervention and feedback. Prospective audit ofantimicrobial use with direct interaction and feedback to the prescriber,performed by either an infectious diseases physician or a clinical pharmacistwith infectious diseases training, can result in reduced inappropriate use ofantimicrobials (A-I).
B. Formulary restriction and preauthorization. Formulary restriction andpreauthorization requirements can lead to immediate and significant reductions inantimicrobial use and cost (A-II) and may be beneficial as part of a multifacetedresponse to a nosocomial outbreak of infection (B-II). The use of preauthorizationrequirements as a means of controlling antimicrobial resistance is less clear,because a long-term beneficial impact on resistance has not been established, andin some circumstances, use may simply shift to an alternative agent with resultingincreased resistance (B-II).

Antimicrobial stewardship programs- The devil is in the detailsCunha CB et al, Virulence 2013; 4:2, 147–149
Antimicrobial stewardship is a developing field, and every program mustbe tailored to its respective institution and each article has a distinctivefocus and perspective.

Global impact of an educational antimicrobial stewardship programme on prescribingpractice in a tertiary hospital centre. Cisneros JM et al, Clin Microbiol Infect 2013 Feb 27
Methodology of active intervention
The main activity of the program consists of a training program directed towards allantibiotic prescribers in the centre based on counselling interviews, carried out bya group of clinical experts who were selected by the PRIOAM operations team,and included 7 ID specialists, 6 critical-care specialists and 4 paediatricians.
PRIOAM advisors were selected from local leaders in the management of patientswith infectious diseases in each area. Each advisor conducted counsellinginterviews in his/her area of responsibility.
The number of counselling interviews scheduled for each clinical department was proportional to its antimicrobial consumption: < 50 DDDs -> one per week,
50 to 100 DDD -> two per week> 100 DDD -> 3 per week.

The advisor reviewed the antimicrobial treatment with the prescriber, examinedthe patient’s clinical data and discussed the main aspects of the prescribedtreatment and diagnosis of the infectious syndrome using a specificquestionnaire.
Prescriptions were considered as ‘appropriate’ when all items of thequestionnaire had been accomplished correctly. If one or more of them wereincorrectly performed, the prescription was evaluated as ‘inappropriate’.
To guarantee homogeneity, the PRIOAM team also coordinated monthly trainingmeetings with these advisors, which also served to monitor the progress of theprogramme.

A total of 1206 CIs were performed during the first year of the programme.Interviews lasted approximately, 10 min, the equivalent of 201 working hoursfor the 1206 CIs.
The most frequently performed assessments were for empirical prescriptions(52.2%, n = 630), followed by targeted treatments (25.4%, n = 306) andsurgical prophylaxis (22.4%, n = 270).

Prospective, randomized trial. Enrolled patients (401 adults who required hospitalization forCAP) were randomly assigned to follow a 3-step critical pathway including early mobilizationand use of objective criteria for switching to oral antibiotic therapy and for deciding onhospital discharge or usual care. Primary End Point: LOS.
The 3-steps of the critical pathway were (1) early mobilization of patients; (2) use ofobjective criteria for switching to oral antibiotic therapy; and (3) use of predefined criteriafor deciding on hospital discharge.
Early mobilization was defined as movement out of bed with a change from the horizontal tothe upright position for at least 20 minutes during the first 24 hours of hospitalization, withprogressive movement each subsequent day during hospitalization, as described elsewhere.Criteria for switching were ability to maintain oral intake; stable vital signs (considered astemperature 37.8°C, respiratory rate <24 breaths/min, systolic blood pressure > 90 mm Hgwithout vasopressor support for at least 8 hours); and absence of exacerbated majorcomorbidities (ie, heart failure, COPD) and/or septic metastases.Predefined criteria for hospital discharge were meeting criteria for switching to oralantibiotic, baseline mental status, and adequate oxygenation on room air (PaO2 60 mm Hg orpulse oximetry >90%).
