Background:
Infection is a common complication seen in ICU patients. Given the correlation between infection and mortality in these patients, a rapid etiological diagnosis and the determination of antimicrobial resistance markers are of paramount importance, especially in view of today's globally spread of multi drug resistance microorganisms. This paper reviews some of the rapid diagnostic techniques available for ICU patients with infections.
Methods:
A narrative review of recent peer-reviewed literature (published between 1995 and 2014) was performed using as the search terms: Intensive care medicine, Microbiological techniques, Clinical laboratory techniques, Diagnosis, and Rapid diagnosis, with no language restrictions.
Results:
The most developed microbiology fields for a rapid diagnosis of infection in critically ill patients are those related to the diagnosis of bloodstream infection, pneumonia -both ventilator associated and non-ventilator associated-, urinary tract infection, skin and soft tissue infections, viral infections and tuberculosis.
Conclusions:
New developments in the field of microbiology have served to shorten turnaround times and optimize the treatment of many types of infection. Although there are still some unresolved limitations of the use of molecular techniques for a rapid diagnosis of infection in the ICU patient, this approach holds much promise for the future.
Insights
Rapid diagnostic techniques are crucial for treating infections in intensive care unit (ICU) patients. Advancements in microbiology offer faster diagnoses and improved treatment, especially for multi-drug resistant organisms.
Area of Science:
- Infectious Diseases
- Critical Care Medicine
- Microbiology
Background:
- Infections are frequent in ICU patients, significantly increasing mortality.
- Rapid etiological diagnosis and antimicrobial resistance detection are vital due to rising multi-drug resistant organisms.
- This review examines rapid diagnostic techniques for ICU infections.
Purpose of the Study:
- To review available rapid diagnostic techniques for infections in ICU patients.
- To highlight the importance of timely diagnosis in critical care settings.
Main Methods:
- A narrative review of peer-reviewed literature from 1995-2014.
- Search terms included 'Intensive care medicine,' 'Microbiological techniques,' 'Clinical laboratory techniques,' 'Diagnosis,' and 'Rapid diagnosis.'
Main Results:
- Rapid diagnostics are most advanced for bloodstream infections, pneumonia (VAP and non-VAP), UTIs, skin/soft tissue infections, viral infections, and tuberculosis.
- Developed fields focus on timely identification of pathogens and resistance markers.
Conclusions:
- Microbiological advancements have reduced diagnostic turnaround times, optimizing patient treatment.
- Molecular techniques show great promise for rapid infection diagnosis in ICUs, despite current limitations.
