To prevent the spread of infectious agents and reduce dissemination of infections
What is the range of activities involved in infection prevention and control?
Surveillance activities, outbreak investigation, and education
What is the role of laboratory scientists in outbreak investigations?
They play a vital role in identifying the source of the outbreak
What is the purpose of national infection control practices?
To assist with assessment, planning, implementation, and evaluation of infection prevention and control programs
What type of infection occurs due to the activities of a health care provider?
Iatrogenic infection
Why do HAIs and iatrogenic infections occur?
Due to the increased use of antimicrobial agents and instrumentation
What is the term for the ongoing, systematic collection of data and analysis of a disease or event?
Surveillance
What is the purpose of collecting data on existing infections in an infection control program?
To recognize an outbreak and direct preventive activities
What is an increase in the occurrence of a disease referred to as?
Outbreak
What type of infection is a catheter-associated urinary tract infection (CAUTI)?
Health care–associated infection
What type of data does infection control surveillance rely heavily on?
Culture review
What does baseline data help in recognizing within a healthcare setting?
Outbreaks
When might an outbreak be suspected in a given setting?
When an unanticipated increase in infections occurs
What type of data does the microbiology laboratory provide to infection control during outbreaks?
Specimen contamination rates
In what scenarios might widespread outbreaks occur?
Outside the confines of a given health care setting
What does a review of culture results help infection control programs with?
Understand what is happening in the community
Why should the laboratory be consulted before environmental surface cultures are undertaken?
To ensure that proper procedures and media are used
In which environmental situations can outbreaks occur due to contaminated water?
Hospitals and swimming pools
What are some examples of multi-drug resistance bacteria mentioned in the text?
ESBL, VRE, MRSA
Which guidelines recommend performing bacteriologic assays of water and dialysis fluids at least once a month?
CDC recommendations
What is the responsibility of the microbiology laboratory beyond providing culture results?
Reporting certain infectious diseases
Why is it important for the laboratory to be aware of standard methods for testing water and dialysis fluids?
To ensure proper procedures and media are used
What was the initial reason for the patient's admission to the intensive care unit?
Confusion and shortness of breath
What type of test was performed on the patient's specimen to identify the microbe?
Antimicrobial susceptibility testing
What was the identification of the microbe that grew in the cultures?
Multidrug-resistant strain of Acinetobacter baumannii
Who was involved in the meeting to discuss the occurrence of the multidrug-resistant strain of Acinetobacter?
Infection prevention and control practitioner, microbiology laboratory scientist, ICU nurse manager, and physician in charge of the ICU
What was implemented as a control measure to prevent the spread of the infection?
Contact precautions
What was the outcome of the implemented control measures?
The occurrence of the multidrug-resistant strain of Acinetobacter decreased and eventually no new cases were observed
