Abstract

Insights

The COVID-19 pandemic altered infection control, potentially increasing multidrug-resistant organism (MDRO) transmission. Reviewing these changes is crucial for preventing nosocomial infections and guiding future practices.

Area of Science:

  • Infectious Diseases
  • Epidemiology
  • Healthcare Management

Background:

  • The COVID-19 pandemic necessitated significant changes in healthcare settings globally.
  • Modifications included infrastructure, ward redesignations, staff redeployments, and altered infection prevention and control (IPC) practices.

Purpose of the Study:

  • To review the potential impacts of COVID-19-related changes on the nosocomial transmission of multidrug-resistant organisms (MDROs).
  • To assess both negative and positive effects of these modifications on MDRO transmission.

Main Methods:

  • Literature review of studies examining IPC and antimicrobial stewardship program (ASP) practices during the COVID-19 pandemic.
  • Analysis of reported outbreaks and changes in baseline rates of MDROs in healthcare facilities.

Main Results:

  • Healthcare facilities worldwide reported MDRO outbreaks during the pandemic.
  • Some centers observed a decrease in baseline MDRO rates due to various factors.
  • Disruptions to IPC and ASP practices may paradoxically increase MDRO transmission.

Conclusions:

  • Changes in IPC and ASP during the pandemic require careful consideration for their collateral effects on MDRO transmission.
  • Proactive strategies are needed to mitigate potential increases in MDROs despite COVID-19 control measures.

Transmission-based Precautions II: Airborne and Protective Environment01:25

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Transmission-based Precautions I: Contact, Enteric, and Droplets

Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Healthcare Associated Infections II: Preventive Measures

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...

Acute Respiratory Failure-V01:29

Acute Respiratory Failure-V

The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.
Ensure that patients are monitored continuously for their response to therapy, including changes in...

Acute Respiratory Failure-I01:21

Acute Respiratory Failure-I

Acute respiratory failure is a condition characterized by the inability of the lungs to perform their primary function: gas exchange. This failure leads to insufficient oxygen levels (hypoxemia) in the blood, elevated carbon dioxide levels (hypercapnia), or both, causing critical impairment in organ function.
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...

Standard Precaution01:26

Standard Precaution

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...
