This section describes interventions to help reduce inappropriate antibiotic use and limit the spread of antibiotic resistance in hospitals (inpatient) and primary care/community (outpatient) settings.
When designing interventions, the closer they are aimed at the provider/prescriber of antibiotics, as opposed to facility or national level, the more effective they have shown to be. It is also important to keep in mind how implementation of one intervention may affect the situation elsewhere. Restricting use of a specific antibiotic or targeting of a specific bacterial pathogen may lead to increased use of other antibiotics or have unintended effects on other bacteria. Each health care facility needs to do their own assessment to understand what is needed and appropriate for their setting, and how to evaluate the work. The section Set up a program provides guidance on how to implement interventions in a structured way.
Persuasive interventions are those that use one or more of the following methods for changing professional behavior: dissemination of educational resources, reminders, audit and feedback, or educational outreach.
Continual education of health care professionals can be a means to keep staff up to date, make them aware of policies, familiar with changes in pharmacotherapy, and allow them to share experiences and learn from discussion with peers. Ideally, passive education should be combined with active interventions; as a standalone initiative passive education has shown to provide only marginal results.
Educational intervention makes an impact on antibiotic prescription patterns at a hospital:
During an outbreak of extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae at a hospital in Sweden, an educational antibiotic intervention was performed aimed at reducing prescriptions of second- and third-generation cephalosporins and preventing increased use of fluoroquinolones and carbapenems.
New recommendations for empirical intravenous antibiotic treatment were communicated to prescribers throughout the hospital by infectious diseases physicians working with the Swedish strategic programme against antibiotic resistance. No restrictive measures were used. A radical immediate and sustained reduction was demonstrated for the cephalosporins targeted in the intervention. Fluoroquinolone and carbapenem use was essentially unchanged. The ESBL outbreak subsided and no increased resistance to the replacement drug was detected during the 2.5 year follow-up. This study clearly demonstrates that an educational intervention can have an immediate and profound effect on antibiotic prescription patterns at a large tertiary hospital.
Restrictive interventions are initiatives that limit the freedom of prescribers/providers to select certain antibiotics. For example, prescriptions of the targeted antibiotics might require approval by an infectious diseases specialist, might be substituted by a pharmacist or completely restricted during the intervention period.
Multifaceted interventions are those that use a combination of approaches to influence the rational use of antibiotics. Persuasive and restrictive antibiotic interventions might be performed in parallel with structural changes or other approaches to improve prescribing practices. This might result a more profound immediate and sustained effect of the intervention than would have been achieved with any of the components alone.
See MEASURE to access tools and resources to assist in assessing the situation and evaluating the effect of interventions. It includes a variety of topics that relates to rational use:
- Burden of antibiotic resistance
- Antibiotic resistance
- Consumption of antibiotics
- Appropriateness of use
- Quality of antibiotics
- Knowledge, attitudes, beliefs and practices – KABP

|Antibiotic stewardship interventions in hospitals in low-and middle-income countries: a systematic review||Systematic review with short description of interventions to improve antibiotic use for hospitalized patients, focusing on low-resource settings (27 studies included). Most studies report positive effects, but the low number of studies and shortcomings in study design makes it hard to draw general conclusions.|
|Global Point Prevalence Survey on Antimicrobial Consumption and Resistance||PPS protocols and methodology – Ongoing project that welcomes new participants from across the world. This open to join project monitors antimicrobial prescribing and resistance in hospital patients on all continents through a “one day survey” and helps design hospital interventions to promote prudent use. Hospitals are welcome to join survey and network (already more than 300 institutions from over 50 countries have participated).

A article with results from the project has been published in the Lancet Global Health.|
