What attributes characterize a good surveillance system?

What attributes characterize a good surveillance system?

Subsequent sections focus on the attributes of a surveillance system (simplicity, flexibility, acceptability, sensitivity, predictive value positive, representativeness, and timeliness) and demonstrate how these combine to affect the usefulness and cost of a system.

What are the elements of a surveillance system?

Each of these sectors contributes to the four basic components of surveillance, which are (1) collection, (2) analysis, (3) dissemination, and (4) response. Collection and analysis can be conducted at the local, state, federal, or international level by public agencies as well as by private industry.

What are the four types of surveillance systems?

Slide 7: Types of Surveillance Passive surveillance, active surveillance, and also syndromic surveillance.

What are the three types of surveillance?

Common Forms of Surveillance

  • Interviews – For a missing person investigation, interviews are paramount to understanding the subject.
  • Physical observation – Physical observation is common for spousal investigations.
  • Electronic – Electronic monitoring is often the tool of choice among investigators.

What are 2 types of surveillance?

  • Corporate.
  • Data mining and profiling.

What is Diseases Surveillance?

1. It involves the ongoing systematic collection, collation, analysis and interpretation of data on disease occurrence and public health related events and dissemination of the information obtained from such data for prompt public health action.

What is an example of syndromic surveillance?

If the attack involved anthrax, for example, a syndromic surveillance system might detect a surge in influenza-like illness, thus, providing an early warning and a tool for monitoring an ongoing crisis.

What is an example of passive surveillance?

Examples of passive surveillance systems include the Food and Drug Administration’s (FDA’s) Adverse Events Reporting System (AERS), which is focused on patient safety, and the Vaccine Adverse Events Reporting System (VAERS), which is operated by the CDC in conjunction with the FDA and is concerned with the negative …

What is the best definition of syndromic surveillance?

Syndromic surveillance is an investigational approach where health department staff, assisted by automated data acquisition and generation of statistical alerts, monitor disease indicators in real- time or near real-time to detect outbreaks of disease earlier than would otherwise be possible with traditional public …

What is the purpose of syndromic surveillance?

The fundamental objective of syndromic surveillance is to identify illness clusters early, before diagnoses are confirmed and reported to public health agencies, and to mobilize a rapid response, thereby reducing morbidity and mortality.

What are syndromic features?

A dysmorphic feature is an abnormal difference in body structure. It can be an isolated finding in an otherwise normal individual, or it can be related to a congenital disorder, genetic syndrome or birth defect. Dysmorphology is the study of dysmorphic features, their origins and proper nomenclature.

What is the difference between active and passive surveillance?

Active surveillance requires substantially more time and resources and is therefore less commonly used in emergencies. But it is often more complete than passive surveillance. It is often used if an outbreak has begun or is suspected to keep close track of the number of cases.

What is the most important use of active surveillance?

Active surveillance is often used to mean monitoring the cancer closely. Usually this includes a doctor visit with a prostate-specific antigen (PSA) blood test about every 6 months and a digital rectal exam (DRE) at least once a year. Prostate biopsies and imaging tests may be done every 1 to 3 years as well.

What is meant by active surveillance?

Listen to pronunciation. (AK-tiv ser-VAY-lents) A treatment plan that involves closely watching a patient’s condition but not giving any treatment unless there are changes in test results that show the condition is getting worse.

What does surveillance mean?

close watch kept over someone

What is the purpose of surveillance?

The purpose of surveillance is to try to detect where disease organisms, such as bacteria and viruses, might be located in Texas in order to predict and prevent human illness. Two main types of surveillance activities are conducted.

What is the importance of surveillance?

Information from surveillance systems can be used to monitor the burden of a disease over time, detect changes in disease occurrence (e.g., outbreaks), determine risk factors for the disease and populations at greatest risk, guide immediate public health actions for individual patients or the community, guide programs …

What are the advantages of disease surveillance?

Benefits from surveillance and response to epidemic-prone infectious disease include health benefits from limiting cases, deaths and disabilities, as well as economic, social and psychological benefits which result from averting outbreaks or controlling them at an early stage.

What are the three objectives of any disease investigation?

The specific objectives of an investigation are to define the parameters of the epidemic (i.e., time of illness onset and conclusion of the epidemic, number of cases, and morbidity and mortality), to identify control or prevention measures, and possibly to identify new data relative to the epidemiology of the health …

What are the objectives of health surveillance?

The objectives for health surveillance are: Protecting the health of employees by early detection of adverse changes or disease; Collecting data for detecting or evaluating health hazards; Evaluating control measures.

Who can carry out a health surveillance?

Medical surveillance should be carried out under the supervision of a qualified occupational health nurse or medical practitioner familiar with the aims of health surveillance and the process you work with.

What are health surveillance requirements?

Health surveillance is required if all the following criteria are met: there is an identifiable disease/adverse health effect and evidence of a link with workplace exposure. it is likely the disease/health effect may occur. there are valid techniques for detecting early signs of the disease/health effect.

Why is epidemiologic surveillance important?

Disease surveillance data is used to determine the need for public health action. During a public health emergency response, epidemiology is used to understand the needs of affected populations, the nature of the disease or exposure, and to inform control activities.

How does disease surveillance work?

Disease surveillance is the systematic collection, analysis and dissemination of data on diseases of public health importance so that appropriate action can be taken to either prevent or stop further spread of disease. It guides disease control activities and measures the impact of immunization services.

Why do we need public health surveillance?

Public health surveillance contributes data and information to assess and characterize the burden and distribution of adverse health events, prioritize public health actions, monitor the impact of control measures, and identify emerging health conditions that may have a significant impact upon population health.

What is the most important aspect of public health surveillance?

Surveillance systems generate data that help public health officials understand existing and emerging infectious and non-infectious diseases. Without a proper understanding of the health problem (etiology, distribution, and mechanism of infection), it will be difficult to ameliorate the health issue.
