Introduction - Scope of the problem
It has been recognized for nearly five decades that up
to 50 percent of antimicrobial use is inappropriate. The consequences of
inappropriate use include increased microbial resistance, toxicity, hospital
lengths of stay, as well as increased costs to patients, hospitals and
payors. Efforts to bring improved appropriate use and reduce resistance have
come from many stakeholders, including professional societies; government and accrediting
organizations; pharmaceutical companies; and a number of state public and
private initiatives. Most recently, Congress has proposed legislation
addressing antimicrobial usage. The Strategies To Address Antimicrobial
Resistance (or STAAR) Act will strengthen federal antimicrobial resistance
surveillance, prevention and control, and research efforts as well as
enhance the collection of critical information on the use of antibiotics in
humans and animals.
The greatest success can be achieved with an institution-wide comprehensive antimicrobial management program that has a multidisciplinary approach and focuses on appropriate selection, dosing, route and duration of antimicrobial therapy.
The goal of all these public and private initiatives is to challenge practitioners to re-evaluate their practices and implement institution-wide policies and procedures regarding appropriate antimicrobial utilization. Antimicrobial stewardship programs (ASPs) are the current standard for meeting these challenges. Such programs seek to optimize antimicrobial selection, dosing, timing and durations of therapy in order to reduce resistance, reduce toxicities and enhance patient outcomes.
There are many resources for hospitals to use as guides for implementing new ASPs or enhancing existing ones. A brief overview of these recommended interventions is provided here with links to selected guidelines and references.
Recommended interventions and solutions
Core components of antimicrobial stewardship programs
- Prospective audit with intervention and feedback
- Concurrent and direct education to prescribers at a patient-specific level on local resistance patterns, clinical literature, antimicrobial selection, dosing and duration of therapy.
- Education has historically been performed by physicians or clinical pharmacists.
- Formulary restriction and pre-authorization, two optimal methods:
- Closed formulary with a defined set of available agents.
- Pre-authorization with prescriber justification.
Suggested supplemental components of
antimicrobial stewardship programs
- Education – education is essential but only marginally effective in the absence of complimentary clinical interventions.
- Multi-disciplinary teams – including physicians, pharmacists, infection control professionals and microbiologists.
- Guidelines and clinical pathways – evidence based practice guidelines incorporating local microbiology data.
- Antimicrobial order forms – requiring physician justification for antimicrobial utilization.
- De-escalation of therapy – utilizing the most narrow spectrum drug to treat a specific infection based upon culture results.
- Dose optimization – using patient specific criteria in conjunction with pathogen
specific criteria to optimally dose antimicrobials. - Computer surveillance and decision support – automating surveillance of antimicrobial utilization, resistance patterns and identification of hospital-acquired infection.
- Monitoring process and outcome measures – both are key elements to assessing the impact and outcomes of stewardship programs.
