abbreviation: BRFSS
Behavioral Risk Factor Surveillance System
The BRFSS is administrated by which organization?
CDC
What does age-adjusted mean?
"equals the playing field" of the reported data d/t a wide range of ages from the initial data... -allows comparison among groups w/o taking age into consideration -takes age out of the picture to show a general concept when age doesn't necessarily impact the data
What type of codes are documented on death certificates?
ICD 10 codes
abbreviation: IHME
Institute for Health Metrics and Evaluation
Which surveillance survey use converted 18-wheeler trucks as mobile labs?
NHANES
Which surveillance system is comparable to BRFSS?

NHIS: -includes children -regional/state-focused instead of national like the BRFSS
abbreviation: NCHS
National Center for Health Statistics
Who is responsible for vital statistics today?
National Center for Health Statistics (NCHS) -part of CDC
abbreviation: NEDSS
National Electronic Disease Surveillance System
abbreviation: NHANES
National Health and Nutrition Examination Survey (*think: HANES underwear --> Fruit of the Loom --> nutrition)
abbreviation: NHIS
National Heath Interview Survey
abbreviation: NPCR
National Program of Cancer Registries
The IHME is an up-and-coming surveillance system. What's a big project that it's working on?
US health interactive maps via geospatial information systems (GIS)
Which university is the IHME based out of?
University of Washington
abbreviation: WHO
World Health Organization
"Syndromic" surveillance began in response to ____.
bio-terrorism after 9/11
abbreviation: COD
cause of death
What is a "con" of the BRFSS?

what does "statistics" mean?
data about the state
What's the main intention of "syndromic" surveillance?
detect a public health emergency ASAP
T/F: The WHO is a type of surveillance system.
false -The WHO reports a lot of data, statistics, health topics, & provides visuals, but it is NOT a surveillance system
T/F: The IHME only reports on national data.
false IHME provides global metrics but also works with the CDC
T/F: The BRFSS is more focused on physical therapy related things (vs public health)
false correct answer: it's more public health related
What are a few examples for what "Exposure/Disease Monitoring Surveillance" would be used for?
long-term data for -cancer -diabetes -COPD
Is BRFSS more national or state-focused?
national
