What Is Antimicrobial Stewardship? Principles, Benefits, and Examples 

Antimicrobial stewardship promotes optimal use of antimicrobial drugs to enhance patient outcomes. Someone of elevated proficiency in antimicrobial prescribing tailors all prescriptions to the individual patient for the duration, and at the dosage and route recommended for that patient. Stewardship also seeks to limit unnecessary or suboptimal use of antimicrobial agents.

The term “antimicrobial” refers to medicines that kill or inhibit the growth of microorganisms. Some antimicrobial medicines are reserved for use against bacterial infections, and are therefore called “antibiotics.” Inappropriate use of these medicines leads to the development of bacterial resistance, making infections difficult to treat.

Current health care systems across the globe have a strong focus on antimicrobial stewardship due to the emergence of antimicrobial resistance (AMR). If health care personnel continue to use antimicrobial agents with great responsibility, these agents will continue to work to treat and eradicate infections in subsequent generations.

Understanding Antimicrobial Stewardship

Antimicrobial Stewardship refers to the way various healthcare professionals including clinicians, pharmacists, nurses, and members of the infection control teams work harmoniously to achieve the best outcome and minimize the negative consequences of the use of antimicrobials.

The goal of antimicrobial stewardship includes:

• The selection of the optimal antimicrobial
• Determining if an infection is likely to benefit from treatment with an antimicrobial
• Appropriate dose and duration of treatment
• Assessing the patient and if needed, change or stop the treatment.

The purpose is not to limit access to essential medicine, but to ensure their optimal and effective use.

Why Is Antimicrobial Stewardship Important? 

Using antimicrobial medicines inappropriately creates numerous challenges to public health. The biggest of these challenges is antimicrobial resistance. Antimicrobial resistance occurs when bacteria or other microorganisms develop resistance to available medicines. The most pertinent example of antimicrobial resistance is the use of antibiotics to treat viral infections. Bacteria develop resistance to antibiotics and future bacterial infections become difficult and expensive to treat. Antimicrobial stewardship includes the following:

• Minimizing the use of unnecessary antibiotics
• Prevention of resistant infections
• Improvement in patient safety
• Decreasing the cost of providing care
• Retaining the effectiveness of currently available medicines

Principles of Antimicrobial Stewardship

Effective antimicrobial stewardship programs employ numerous strategies; however, for the purpose of simplicity, we can identify five principles.

Right Diagnosis Before Treatment

Healthcare providers must determine whether an infection is truly present and, if it is, what is causing the infection. Not every febrile or infection-like symptom requires antibiotics.

Healthcare providers use the following:

• History
• Exam
• Lab work
• Microbiology reports

to determine if treatment with antimicrobials is warranted.

Right Antimicrobial Selection

A number of factors are considered to choose the most appropriate treatment. These may include:

• Nature of the infection
• Location of the infection
• Patient’s age and health
• Patient’s history
• Local resistance patterns

Broad spectrum antibiotics should not be used if a narrow spectrum antibiotic would be more appropriate.

Correct Dose and Administration

Dosing must be determined with consideration for the age, weight, health status, kidney function, and the severity of the infection of the patient. Incorrect dosing results in treatment failure and resistance.

Treatment for the Appropriate Duration

Using antibiotics longer than considered necessary increases the risks of side effects and the development of resistance.

Stewardship promotes the prescribing of the shortest treatment duration that is effective based on evidence, the patient, and the prevailing situation.

Monitoring and Review

Patients receiving antimicrobials should be monitored for:

• Signs and symptoms
• Lab work
• Adverse effects
• Need for continuation, change, or discontinuation of treatment

This ensures appropriate, safe and effective treatment.

Education and Awareness

Teaching healthcare professionals and patients to appreciate the importance of judicious prescription and completion of antimicrobial therapy is a key pillar of antimicrobial stewardship. The reasons for the judicious prescription of antibiotics include:

• Understanding when to prescribe antibiotics
• Understanding the completion of the full course of therapy is critical for the intended outcome
• Sharing of antibiotics is unsafe
• Self medication should be avoided

Benefits of Antimicrobial Stewardship

Antimicrobial stewardship offers benefits for the healthcare system, the communities they serve, and, in turn, their patients.

Resistant Microbe Management

The principal benefit of stewardship is the decreased development and spread of resistance. The continued effectiveness of existing treatments is dependent on the rational use of antimicrobial agents.

Positive Patient Outcomes

Correct use of antimicrobials leads to the patient having improved positive treatment outcomes of faster recovery time with fewer complications.

Limiting Side Effects

The use of antimicrobial agents causes side effects beyond the intended treatment outcomes. These can include both systemic and local effects that complicate the patient’s recovery.

Reduced Resource Overutilization

Correct use of therapeutics leads to a reduction in ancillary and extended treatment and recovery times.

Preserving Therapeutic Options

The rational use of antimicrobials preserves therapeutic options for future patients.

Antimicrobial Stewardship at Different Levels

Antimicrobial stewardship has applications in hospitals, clinics, and community healthcare settings.

Example 1: Avoiding Unnecessary Antibiotics

A patient comes down with a cold and visits a doctor hoping for a prescription of antibiotics. The doctor doesn’t prescribe antibiotics because the cold is a viral infection and a doctor’s visit is unnecessary.

Example 2: Using a Narrower Spectrum Antibiotic

A patient was prescribed broad spectrum antibiotics for serious infection. Upon further testing, the doctors discovered the bacteria clinical isolate and prescribed a targeted antibiotic.

Example 3: Changing Antibiotic Therapy Based on Response

An antibiotic therapy review process is conducted daily by hospital teams for all patients who are hospitalized receiving antibiotic therapy. If the patient’s clinical status improves and is no longer indicated, the antibiotic therapy is altered in accordance with therapeutic guidelines.

Example 4: Counseling Against Self-Medication

Programs that deliver healthcare education promote the importance of avoiding the use of antibiotics that are leftover from previous patient’s therapy, and the unadvised use of antibiotics.

Role of Healthcare Professionals in Antimicrobial Stewardship

Several healthcare professionals contribute to successful stewardship programs.

Doctors

Doctors must correctly diagnose their patients and select the best treatment, as well as occasionally review treatment plans.

Pharmacists

Pharmacists help select the correct medication and dose, account for drug interactions, and educate patients.

Nurses

Nurses help with administering medications, personnel observation, and cultivating a patient’s awareness of their own health and well-being.

Infection Control Teams

These teams help recognize patterns of resistant infections and develop control measures for their spread.

Antimicrobial Stewardship in Hospitals

Antimicrobial stewardship programs within hospitals are responsible for:

• Reviewing antibiotic orders
• Developing antibiotic use policies
• Trending resistance patterns
• Providing staff education and training
• Improving infection control

These programs ensure optimal safety of antimicrobial utilization across hospitals.

How Patients Can Support Antimicrobial Stewardship?

Patients also have key roles when they

• Only take medicine when prescribed
• Follow the doctor’s orders
• Do not give medicine to others
• Dispose of leftover antibiotics
• Speak to health care professionals regarding treatment

Responsible use of medicine protects the health of individuals and the public.

Conclusion 

Antimicrobial stewardship involves maintenance and protection of the efficacy and safety of antimicrobial medicines. Stewardship programs emphasize appropriate diagnosis, selection of the right medicine, correct dosing, and safe use and improve patient care and reduce the concern of antimicrobial resistance.

The promotion of the appropriate use of antimicrobial medicines is a combined effort of the medical and pharmacy practice, healthcare organization, and the patient. The preservation of treatment of difficult to treat infections and the protection of future generations from these fears is the goal of antimicrobial stewardship.

FAQS

Why is antimicrobial stewardship critical?

Without antimicrobial stewardship, antibiotic resistance will be more widespread, patients will receive less appropriate treatment, antimicrobial medicines will be wasted, and future generations will have fewer accessible treatments.

Does antimicrobial stewardship equal not taking any antibiotics?

Absolutely not. Antimicrobial stewardship is using antibiotics and other antimicrobial drugs when they are needed and under the right prescription, which includes the right medicine, dose, and duration.

What are some patient-level stewardship activities?

Patients can take only the medicines that have been prescribed for them, complete the treatment, avoid taking medicines on their own, do not hand out their antibiotics to others, and follow what their health care workers advise them to do.
