SURVEILLANCE o Surveillance? What are uses of it? Purpose of surveillance? Disease surveillance is the ongoing systematic collection, analysis, interpretation, of health-related data essential to planning,implementation, and evaluation of public health practice, closely integrated with the timely dissemination of these data to the responsible prevention and control It is built on understanding of epidemiology - agent, host, environment, and the natural history of disease o Goal of health surveillance is to provide information that can be used for health action by public health personnel,
government leaders, and the public to guide public health policy and programs. o USES OF SURVEILLANCE Estimate the magnitude of a problem Determine geographic distribution Detect epidemics; define the problem Generate hypotheses; stimulate research Evaluate control measures Monitor changes in infectious agents Detect changes in health practices Facilitate planning o PURPOSES OF SURVEILLANCE Assess public health status Define public health priorities Evaluate programs Stimulate research. Surveillance helps public health departments identify trends and usual disease patterns, set priorities for using scarce resources, and develop and evaluate programs for commonly occurring and universally occurring diseases or events. o Data sources for surveillance Mortality data Morbidity data What is NNDS? Know about reporting to NNDS by each state to the CDC weekly. How would you use a case definition? KNow the types of surveillance systems and examples of each. Know about doing an investigation - steps/when to investigate. o NNDS National notifiable disease surveillance system o Reporting to NNDS Physicians, labs, or other health care providers are required to report Each state determines which diseases and conditions are reportable in their jurisdiction, and they decide which ones from the list of nationally notifiable diseases or conditions they will report for their state. CDC and CSTE collaborate closely on the national list. It is revised yearly and therefore varies somewhat from year to year. States typically fully cooperate with national disease reporting because CDC publishes the provisional data weekly in the Morbidity and Mortality Weekly Report , or MMWR , and the final data annually in the MMWR Annual Summary of Notifiable Diseases . MMWR displays the data in complex tables and in maps, such as the one displayed
on this slide. This allows each state to know how their population’s health compares with other states. Regulation can vary by state Legally reportable diseases - data is electronically sent each week to the CDC o Case definition Essential for establishing a uniform, standardized method of reporting and monitoring diseases Understanding of the data being collected Reducing the chance that different criteria will be used for reporting similar cases of a disease Standard case definitions are NOT there to provide ease of copying similar results quickly and efficiently from one case to the next.
