Determining the presence of a hospital acquired infection requires an infection control practitioner ICP to review a patient's chart and see if the patient had the signs and symptom of an infection. Surveillance definitions exist for infections of the bloodstream, urinary tract, pneumonia, surgical sites and gastroenteritis. Surveillance traditionally involved significant manual data assessment and entry in order to assess preventative actions such as isolation of patients with an infectious disease. Increasingly, computerized software solutions are becoming available that assess incoming risk messages from microbiology and other online sources.
By reducing the need for data entry, software can reduce the data workload of ICPs, freeing them to concentrate on clinical surveillance. As of , approximately one third of healthcare acquired infections were preventable. CDC found in the s that hospitals reduced their nosocomial infection rates by approximately 32 per cent by focusing on surveillance activities and prevention efforts. In the health care context, medical isolation refers to various physical measures taken to interrupt nosocomial spread of contagious diseases.
Various forms of isolation exist, and are applied depending on the type of infection and agent involved, to address the likelihood of spread via airborne particles or droplets, by direct skin contact, or via contact with body fluids. In cases where infection is merely suspected, individuals may be quarantined until the incubation period has passed and the disease manifests itself or the person remains healthy. Groups may undergo quarantine, or in the case of communities, a cordon sanitaire may be imposed to prevent infection from spreading beyond the community, or in the case of protective sequestration , into a community.
Public health authorities may implement other forms of social distancing , such as school closings, to control an epidemic. When an unusual cluster of illness is noted, infection control teams undertake an investigation to determine whether there is a true outbreak, a pseudo-outbreak a result of contamination within the diagnostic testing process , or just random fluctuation in the frequency of illness.
If a true outbreak is discovered, infection control practitioners try to determine what permitted the outbreak to occur, and to rearrange the conditions to prevent ongoing propagation of the infection. Often, breaches in good practice are responsible, although sometimes other factors such as construction may be the source of the problem. Outbreaks investigations have more than a single purpose. These investigations are carried out in order to prevent additional cases in the current outbreak, prevent future outbreaks, learn about a new disease or learn something new about an old disease.
Reassuring the public, minimizing the economic and social disruption as well as teaching epidemiology are some other obvious objectives of outbreak investigations. According to the WHO , outbreak investigations are meant to detect what is causing the outbreak, how the pathogenic agent is transmitted, where it all started from, what is the carrier, what is the population at risk of getting infected and what are the risk factors.
The results of outbreak investigations are always made public in the means of a report in which the findings are communicated to the authorities, media, scientific community and so on.
These reports are commonly used as pedagogical tools. Practitioners can come from several different educational streams. Many begin as nurses, some as medical technologists particularly in clinical microbiology , and some as physicians typically infectious disease specialists. Specialized training in infection control and health care epidemiology are offered by the professional organizations described below. Physicians who desire to become infection control practitioners often are trained in the context of an infectious disease fellowship.
In the United States, Certification Board of Infection Control and Epidemiology is a private company that certifies infection control practitioners based on their educational background and professional experience, in conjunction with testing their knowledge base with standardized exams. It is recommended that one has 2 years of Infection Control experience before applying for the exam.
Certification must be renewed every five years. A course in hospital epidemiology infection control in the hospital setting is offered jointly each year by the Centers for Disease Control and Prevention CDC and the Society for Healthcare Epidemiology of America. In , the Royal Australian College of General Practitioners published a revised standard for office-based infection control which covers the sections of managing immunisation, sterilisation and disease surveillance.
Currently, the federal regulation that describes infection control standards, as related to occupational exposure to potentially infectious blood and other materials, is found at 29 CFR Part From Wikipedia, the free encyclopedia.

Infection is the process where an infectious agent microorganism invades and multiplies in the body tissues of the host resulting in the person developing clinical signs and symptoms of infection E. Increased temperature, rigors, rash. Skip to main content. Basic Principles Introduction Infection prevention and control is the application of microbiology in clinical practice.
The chain of infection The process of infection can be represented as a chain, along which microorganisms are passed from a source to a vulnerable person. Opportunities to break the chain of infection Transmission may be interrupted when: The infectious agent is eliminated, inactivated or cannot survive in the reservoir E.
Hand Hygiene, appropriate use of PPE, safe packaging and disposal of waste Transmission does not occur due to good infection prevention and control practices E. Hand Hygiene, isolation of infected patients, air flow control where appropriate The portal of entry is protected E. Aseptic non-touch technique, safe catheter care, wound care Reducing the susceptibility of patients receiving healthcare E.
Treatment of underlying disease, recognising high risk patients The difference between Colonisation and Infection Colonisation Colonisation is when microorganisms, including those that are pathogenic, are present at a body site E.
