Quiz 9: Antimicrobial stewardship
Please choose the one, most correct answer to each question or statement.
- Antimicrobial resistance is:
- The ability of pathogens to multiply under difficult circumstances
- The ability of pathogens to multiply in healthcare environments
- The ability of pathogens to grow in the presence of a drug that would normally kill them
- The ability of pathogens to overcome the human host’s immune defences.
- Antimicrobial resistance:
- Results in better outcomes for patients
- Has decreased costs of treatment for common infections
- Is not a common problem worldwide
- Makes available antimicrobials less effective and infections more difficult to treat.
- The development of antimicrobial resistance is:
- An entirely preventable phenomenon
- An inevitable phenomenon as pathogens evolve and adapt to new environments
- Unaffected by antimicrobial usage
- Not a problem as new antimicrobials are being developed constantly.
- Antimicrobial resistance in healthcare facilities is spread mainly by:
- Poor IPC practices (including poor hand hygiene compliance)
- Use of antibiotics as growth promoters in animal farming
- Inadequate environmental cleaning
- Exposure of pathogens to disinfectants.
- Patients with antimicrobial resistant infections:
- Are less likely to die from their infection than patients with drug-sensitive pathogens
- Are more likely to die from their infection than patients with drug-sensitive pathogens
- Have shorter duration of hospitalisation than patients with drug-sensitive pathogens
- Cost less to treat than patients with drug-sensitive pathogens.
- Antimicrobial stewardship programmes:
- Aim to improve patient outcomes
- Raise awareness of the problem of antimicrobial resistance
- Encourage rational usage of antimicrobials
- All of the above.
- The most important reason to implement antimicrobial stewardship is:
- To conserve the effectiveness of antimicrobials for the future
- To save healthcare facilities money
- To limit the number of antimicrobials that doctors can prescribe
- To avoid patients developing side-effects from antimicrobials.
- The negative consequences of antibiotic overuse and misuse are called:
- Consequent damage
- Collateral damage
- Concomitant damage
- Consequential damage.
- The ideal antimicrobial stewardship committee should be made up of:
- Clinicians (doctors and nurse practitioners) and data managers
- Hospital management, a microbiologist and a senior doctor
- Pharmacy, the IPC practitioner and a senior doctor
- A manager, clinician, pharmacist, microbiologist, data manager and IPC practitioner.
- Information on antimicrobial usage can be used by the stewardship committee to:
- Identify high usage drugs and clinical areas that use them most
- Punish individual ‘high-volume’ prescribers
- Impose penalties on the clinical areas with highest usage
- Draw up local guidelines for antimicrobial usage.
- Essential resources needed for an antimicrobial stewardship programme include:
- Significant funding or financial resources from the healthcare facility
- An infectious diseases physician
- A pharmacist with training in infectious diseases
- An enthusiastic and dedicated antimicrobial stewardship programme committee.
- Antimicrobial stewardship programmes can save healthcare facilities money by:
- Saving patients’ lives
- Reducing length of hospitalisation and avoiding unnecessary drug usage
- Preventing spread of drug-resistant pathogen
- Preventing colonisation of staff members with resistant pathogens.
- The IPC practitioner contributes to antimicrobial stewardship through:
- Multiple activities that reduce the spread of resistant pathogens
- Reporting poor IPC practices to the healthcare facility manager
- Performing daily ward rounds in the clinical areas
- Advising clinicians on incorrect prescribing practices.
- Empiric antimicrobial therapy:
- Is given routinely before appropriate microbiological specimens have been taken
- Consists usually of a single antimicrobial drug that targets the most likely pathogen
- Usually includes several anti-infective drugs that cover the most likely causative pathogens
- Is continued even after the definitive cause of the infection is identified.
- Targeted antimicrobial therapy:
- Aims to match the antimicrobial given to the specific pathogen-causing infection
- Uses broad-spectrum antibiotics to cover all potential pathogens
- Does not require the collection of appropriate microbiological specimens
- Usually requires several different antimicrobials to be prescribed.
- Selective reporting:
- Involves microbiologists phoning clinicians to inform them of drug-resistant pathogens
- Presents clinicians with all possible antimicrobial treatment options for confirmed pathogens
- Discourages prescribers from using targeted antimicrobial therapy
- Presents clinicians with only the most narrow-spectrum antimicrobials that the pathogen is sensitive to.
- De-escalation of antimicrobial therapy:
- Means changing the patient’s prescription from a narrow to a broad-spectrum antimicrobial
- Is potentially harmful, even if the pathogen is sensitive to a narrow-spectrum antimicrobial
- Ensures effective therapy but reduces harmful effects of broad-spectrum antimicrobials
- Means that therapy should be stopped or discontinued.
- Prolonged courses of antimicrobials:
- May encourage the development of antimicrobial resistance
- Do not increase the risk of side-effects for patients
- Are needed as prophylaxis for patients undergoing surgical procedures
- Are needed for all patients with serious infections.
- An antimicrobial restriction policy:
- Prevents clinicians from accessing essential antimicrobials
- Limits access to selected antimicrobials, without prior approval from a senior person
- Should be implemented identically at all healthcare facilities
- Does not need clinicians with insight into antimicrobial management to be available.
- Antimicrobial prescription guidelines:
- Should be based on international antimicrobial recommendations
- Are unhelpful when implementing antimicrobial stewardship
- Give recommendations on antimicrobial selection, dose and duration based on local data
- Give recommendations on which brands of antimicrobials to use.
