HSCI Lecture 4
- where does the public health information come from?
- data collection through public health surveillance
Sources of PH Data 6Ss
- single cases (rare or new diseases)
- statistical ("vital" stats and reportable diseases): routine data collection in every
country. registering deaths and births. reporting system is not as quick
- surveys (sampling): government collected data. some surveys can be very large.
very important source of health related information.
- self-reporting (adverse effects of drugs and vaccines): if people are on drug
treatment or a child was vaccinated, a patient might see side effects and will report it.
not very reliable source of information. important to include in surveys though.
- sentinel monitoring ("real-time monitoring"): important for widespread diseases
like influenza and diseases that are expected (seasonal outbreaks of influenza) can
catch very early cases of influenza
- syndromic surveillance (unexpected events- outbreaks, bioterrorism): start by
investigating symptoms that people complain and report on
- integrated data systems of databases
