Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic01:26

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

4.4K
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Healthcare Associated Infections II: Preventive Measures

2.8K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Enzyme-Linked Immunosorbent Assay

14.2K
In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen.  Enzyme-substrate reaction allows the antigen to be visualized or...

Area of Science:

  • Critical Care Medicine
  • Cardiology
  • Health Informatics

Background:

  • Sepsis diagnosis in research can be improved.
  • Existing methods for defining sepsis in databases may lack precision.

Discussion:

  • The Sepsis-3.0 criteria, incorporating the SOFA score and evidence of infection, offer a more refined approach to sepsis diagnosis.
  • The MIMIC-IV database contains a derived table specifically designed for Sepsis-3.0, facilitating improved cohort identification.
  • Implementing Sepsis-3.0 criteria enhances the clinical relevance and accuracy of research involving septic patients with new-onset AF.

Key Insights:

  • Suggests Sepsis-3.0 criteria over ICD codes for improved sepsis diagnosis in new-onset AF patients within the MIMIC-IV database.
  • Highlights the availability of Sepsis-3.0 derived data in MIMIC-IV for enhanced cohort definition.
  • Advocates for the adoption of Sepsis-3.0 to increase the robustness and clinical applicability of research findings.

Outlook:

  • Future research on new-onset AF in sepsis should prioritize the Sepsis-3.0 definition for enhanced diagnostic accuracy.
  • Performing sensitivity analyses using different sepsis definitions can further strengthen the reliability of study results.
  • The integration of Sepsis-3.0 criteria in large databases like MIMIC-IV is crucial for advancing critical care and cardiology research.
