Total questions: 30
Worksheet time: 15mins
What is one of the primary goals of formal antimicrobial stewardship programs in the inpatient setting?
To increase the use of broad-spectrum antibiotics
To achieve optimal clinical outcomes related to antimicrobial use
To eliminate the need for infection control programs
To reduce the number of hospital staff
What is the main advantage of preauthorization as a strategy in antimicrobial stewardship?
It increases the use of unnecessary antibiotics
It reduces initiation of unnecessary and inappropriate antimicrobials
It delays patient care
It eliminates the need for pharmacist involvement
Why is collaboration with infection control programs important in antimicrobial stewardship?
To increase the spread of resistance
To minimize the spread of resistance
To reduce the number of clinicians involved
To eliminate the need for audits
Which antibiotics are noted for having high bioavailability and can be converted from IV to oral therapy?
Penicillins and cephalosporins
Fluoroquinolones and linezolid
Vancomycin and gentamicin
Amoxicillin and erythromycin
Which of the following is an example of a program that can help reduce nephrotoxicity and improve time to therapeutic levels?
Vancomycin and aminoglycosides per pharmacy
Routine use of broad-spectrum antibiotics
Prolonged use of oral antibiotics
Avoiding all antibiotic use
What is a key strategy to decentralize routine antibiotic review?
Self-stewardship and antibiotic timeouts
Increasing antibiotic prescriptions
Eliminating all checklists
Ignoring stop orders
Why is education alone considered a weak intervention in antimicrobial stewardship programs?
It is best used with other interventions for sustained effects
It always leads to resistance
It is never effective
It increases infection rates
When designing interventions for antifungal stewardship, what should programs consider?
Local epidemiology and antifungal resistance rates
Only national guidelines
Patient preferences only
Cost of medications only
In what situation might therapeutic drug monitoring (TDM) be especially helpful?
Patients failing therapy or with deep-seated disseminated disease
Patients with mild infections
All patients regardless of condition
Patients with no risk factors
What is the primary reason for setting up an Antimicrobial Stewardship Program (ASP) in a hospital?
To reduce hospital staff workload
To improve quality and lower costs by managing antimicrobial use
To increase the number of hospital beds
To promote hospital branding
Which of the following is NOT listed as a type of priority that may be considered strategic for a hospital?
Clinical
Operational
Financial
Recreational
Which of the following is a caveat mentioned when setting goals for antimicrobial use in an ASP proposal?
The goal should be to eliminate all antimicrobials
The goal should be appropriate to use, not just reduction in use
The goal should focus only on financial savings
The goal should ignore baseline data
Why might hospital leaders view a phased implementation of a stewardship program as beneficial?
It demonstrates a commitment to achieving targets over time and builds faith in the partnership
It allows for immediate full-scale implementation
It reduces the need for any monitoring or updates
It eliminates the need for compliance with guidelines
Which metric is less sensitive to variability in dosing and is endorsed as the standard by the CDC's antimicrobial utilization module?
Defined Daily Dose (DDD)
Days of Therapy (DOT)
Milligram per kilo dosing
Patient days
What is the main reason for applying rules to exclude repeat isolates in a given time window when measuring antimicrobial susceptibility?
To increase the number of isolates in the report
To avoid biased results from patients with multiple isolates
To reduce the workload for laboratory staff
To ensure all organisms are included in the report
What is a key challenge when comparing your institution’s data to other groups?
Ensuring that a comparator really represents a good benchmark for your institution
Collecting data from your own institution
Setting an absolute standard goal
Ignoring background variability
Which of the following is a common mistake when analyzing data longitudinally in antimicrobial stewardship?
Overstating the effects of your program due to random variability
Using absolute standard goals
Comparing to other hospitals
Tracking long-term trends
How can tracking stewardship metrics over longer time periods be beneficial?
It can account for seasonal and other fluctuations, revealing long-term trends
It eliminates all background variability
It always shows a downward trend
It makes month-to-month noise more apparent
Suppose you observe a downward trend in vancomycin use over eight months, but there are substantial month-to-month variations. What should you consider before concluding that your stewardship program is successful?
The variations may be part of background variability and not a true effect
The trend is always due to the program’s success
The data should be ignored if it fluctuates
Only the last month’s data matters
If you want to ensure that your data analysis reflects a real effect rather than random variation, what should you do?
Use adequate data and the best techniques to estimate intervention effects
Only compare to other hospitals
Ignore fluctuations in the data
Use a single month’s data for analysis
What is the purpose of applying confidence intervals or error bars to data points in a study?
To indicate the degree of uncertainty around estimates and reduce the likelihood of overstating trends
To make the data look more complex
To hide errors in the data
To increase the number of data points
According to the passage, what is the most valid way to analyze and present data measured at repeated intervals over time after an intervention?
Interrupted time series analysis
Comparing only the mean values before and after intervention
Ignoring trends and focusing on random variation
Using only the data from the intervention period
Why might comparing the mean value of a metric before and after an intervention give an incomplete or false interpretation?
It does not account for underlying trends and changes in level over time
It always overestimates the effect
It is the simplest statistical method
It uses too many data points
How does patient mix affect antimicrobial utilization rates in hospitals?
It has no effect on utilization rates
Hospitals with more high-use patients have higher total utilization
Only the number of doctors affects utilization rates
Utilization rates are always the same regardless of patient mix
What is the benefit of plotting antibiotic usage among patients on particular services in each hospital, as described in the text?
It allows comparison of similar patient groups, removing the effect of different patient mixes
It increases the complexity of data analysis
It hides differences between hospitals
It reduces the need for benchmarking
According to the passage, what was surprising about UCSF's vancomycin use compared to other hospitals?
UCSF had the second highest usage in its group, much more than lower end institutions
UCSF used no vancomycin at all
UCSF had the lowest usage of vancomycin in the group
UCSF only used vancomycin for non-bacterial infections
What did the surveillance data suggest about MRSA rates during the period of increased vancomycin use?
MRSA rates were actually flat, not increasing
MRSA rates were rapidly increasing
MRSA rates were decreasing dramatically
MRSA rates were unknown due to lack of data
What percentage of all adult admissions for any indication were receiving vancomycin during their hospitalization, according to the text?
10 percent
15 percent
25 percent
50 percent
What is the primary purpose of a clinical decision support system?
To help identify opportunities and add efficiency to the intervention process
To replace the decision of a clinician
To diagnose diseases automatically
To prescribe medication without human input
Which of the following best describes the main difference between EHR-integrated and third-party clinical decision support systems?
Whether the user has to go into a separate system to view the alerts
The type of medication prescribed
The number of clinicians using the system
The cost of the system
