What is purpose of surveillance?

What is purpose 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 principles of surveillance?

A high-quality public health surveillance system: Involves and encourages the community to report all cases of diseases and other health problems. Uses both active and passive surveillance for effective disease control and prevention. Collects only useful data, using a simple data collection method.

What is the main purpose of epidemiologic surveillance?

Epidemiological surveillance is defined as the “ongoing systematic collection, analysis, and interpretation of health data that are essential to the planning, implementation, and evaluation of public health practice” (25).

What are surveillance activities?

Surveillance Activities In addition, various methods for conducting surveillance are used to collect information, depending on disease incidence, specificity of clinical presentation, available laboratory testing, control strategies, public health goals, and the stage of the vaccination program.

What does surveillance mean?

close watch kept over someone

What is infection control surveillance?

Infection surveillance data is used to measure success of infection prevention and control programs, to identify areas for improvement, and to meet public reporting mandates and pay for performance goals.

What is Outcome surveillance?

Outcome surveillance is the measurement of the rates and consequences of health care-associated infections (HAI), including but not limited to the following few variables: HAI rates, mortality, extra length of stay, attributable cost, and bacterial resistance.

How is HAI rate calculated?

To determine HAI rates, divide the numerator (i.e., the number of new cases of infection for the period of review) by one of several denominators (e.g., average census or patient population, total patient or resident days, or device days).

What does per 1000 patient days mean?

Add up the total occupied beds each day for the month (patient bed days). Divide the number of falls by the number of patient bed days for the month. Multiply the results by 1,000 to get the fall rate per 1,000 patient bed days.

How do you calculate rate per 100000?

A crime rate is calculated by dividing the number of reported crimes by the total population. The result is then multiplied by 100,000. For example, in 2014 there were 48,650 robberies in California and the population was This equals a robbery crime rate of 126.4 per 100,000.

What is HAI infection?

Health care-associated infections (HAIs) are infections people get while they’re receiving health care for another condition. HAIs can happen in any health care facility, including hospitals, ambulatory surgical centers, end-stage renal disease facilities, and long-term care facilities.

What are the three common types of HAIs?

Major Types of HAIs​

• Catheter-associated urinary tract infection (CAUTI)
• Central line-associated bloodstream infection (CLABSI)
• Surgical site infection (SSI)
• Ventilator-associated events (VAE)

What is the most common HAI infection?

• Surgical-site infection: 21.8 percent.
• Gastrointestinal infection: 17.1 percent.
• Urinary tract infection: 12.9 percent.
• Primary bloodstream infections: 9.9 percent.
• Eye, ear, nose, throat or mouth infection: 5.6 percent.

What are the four 4 most common hospital-acquired infections?

Hospital-acquired infections are caused by viral, bacterial, and fungal pathogens; the most common types are bloodstream infection (BSI), pneumonia (eg, ventilator-associated pneumonia [VAP]), urinary tract infection (UTI), and surgical site infection (SSI).

What kinds of germs can cause HCAIs?

Healthcare associated infections (HCAI)

• MRSA. Meticillin resistant staphylococcus aureus (MRSA) is a type of staphylococcus aureus that has become resistant to the antibiotic Meticillin and some other commonly used antibiotics.
• Clostridium difficile.
• Norovirus.
• Seasonal influenza (flu)

What is the most common infection in hospital?

The most common types of infection acquired in hospitals are:

• bloodstream infection.
• urinary tract infection (UTI)
• wound infection.
• pneumonia (lung infection).

What are the most common healthcare acquired infections?

The 6 most common types of healthcare-associated infections, which accounted for more than 80% of all healthcare-associated infections, were pneumonia and other respiratory infections (22.8%), urinary tract infections (17.2%), surgical site infections (15.7%), clinical sepsis (10.5%), gastrointestinal infections (8.8%) …
