Kinds of surveillance (+ vs. -) Flashcards
What are the advantages and disadvantages of passive surveillance?
Benefits: Relatively simple and less expensive to implement, suitable for monitoring common diseases, and often relies on existing data sources like hospital records.
Disadvantages: Likely to underreport cases, may lack comprehensive data on the disease, and doesn’t actively search for cases, which can lead to delays in response and intervention.
What are the advantages and disadvantages of active surveillance?
Benefits: Provides more accurate and comprehensive data, allows for timely detection and response to outbreaks, and ensures a more complete understanding of disease patterns.
Disadvantages: Resource-intensive, requiring substantial time, effort, and funding, and may not be sustainable for long periods for certain diseases, especially those with low incidence rates.
What are the advantages and disadvantages of sentinel surveillance?
Benefits: Provides an early warning system for emerging health issues, allows for targeted monitoring of specific populations, and provides a representative sample for understanding broader trends.
Disadvantages: Might not fully represent the entire population, limited in its ability to capture the complete disease burden, and may not be suitable for detecting rare diseases.
What are the advantages and disadvantages of syndromic surveillance?
Benefits: Can provide real-time or near real-time information, enables the detection of unusual patterns or outbreaks quickly, and can be effective for monitoring non-specific symptoms.
Disadvantages: May generate false alarms or unnecessary responses, requires sophisticated data collection and analysis methods, and might not provide a definitive diagnosis or confirmation of the specific disease.
