What is a 'control group' in a dispatch intervention study?
Answer: The group that does not receive the experimental intervention
The control group receives no intervention or the standard treatment, providing a baseline against which the experimental intervention is compared.
Which measure of central tendency is MOST resistant to extreme outliers in dispatch response time data?
Answer: Median
The median is the middle value and is not affected by extreme outliers, making it more representative of typical response times than the mean.
A dispatch center implements a new protocol and tracks outcomes for 12 months. This is best described as:
Answer: Prospective longitudinal study
A prospective longitudinal study follows participants forward in time after an intervention to observe outcomes over a defined period.
What is 'recall bias' in research involving dispatcher self-reports?
Answer: Inaccurate recollection of past events affecting data reliability
Recall bias occurs when participants inaccurately remember past events, systematically distorting self-reported data.
In evidence-based dispatch, a 'clinical practice guideline' is best described as:
Answer: Systematically developed recommendations to guide practitioner decisions
Clinical practice guidelines are systematically developed statements that synthesize evidence to guide practitioner decision-making in specific situations.
Which study design is most appropriate when a researcher wants to investigate the cause-effect relationship between dispatcher stress and protocol errors?
Answer: Experimental study with random assignment
An experimental study with random assignment allows researchers to establish cause-and-effect relationships by controlling for confounding variables.
What does 'number needed to treat' (NNT) indicate in dispatch protocol research?
Answer: How many patients must receive an intervention for one additional patient to benefit
NNT represents how many patients must receive an intervention for one additional patient to achieve a beneficial outcome, helping assess clinical practicality.
