Abstract

Insights

This study found a high prevalence of multidrug-resistant germs in surgical departments, often causing nosocomial infections. Understanding resistance patterns is key to combating these dangerous hospital-acquired infections.

Area of Science:

  • Medical Microbiology
  • Infectious Diseases
  • Hospital Epidemiology

Background:

  • Nosocomial infections pose a significant threat in surgical settings.
  • Multidrug-resistant (MDR) germs are a growing concern in healthcare environments.
  • Understanding resistance mechanisms is crucial for effective treatment and prevention.

Purpose of the Study:

  • To determine the prevalence of MDR germs with nosocomial potential in surgical departments.
  • To identify the primary resistance phenotype and genotype patterns of these germs.
  • To assess the role of MDR germs in surgical site and urinary tract infections.

Main Methods:

  • Germ identification using the API system (BioMerieux).
  • Antimicrobial susceptibility testing via disk-diffusion (CLSI standards) with automatic reading (Osiris-Bio Rad).
  • Genotyping of ESBL-producing E. coli and Klebsiella pneumoniae strains.

Main Results:

  • 106 microbial strains with nosocomial potential were isolated from 190 samples.
  • Enterobacteria comprised 52.83% of isolates, followed by Gram-negative non-fermentative rods (24.52%) and Gram-positive cocci (22.64%).
  • A high prevalence of MDR germs, including ESBL and MRSA, was observed.

Conclusions:

  • MDR germs are highly prevalent in surgical departments.
  • These MDR germs are frequently implicated in nosocomial surgical site and urinary tract infections.
  • The findings highlight the need for robust infection control measures and surveillance of resistance patterns.

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...
Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
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...

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...
Asepsis01:28

Asepsis

The condition of being free from disease-causing living pathogens is asepsis. Aseptic techniques include a set of standard practices to achieve asepsis. An example is the regular environmental cleaning of all parts of the healthcare facility and hand hygiene at home before preparing or eating food. Medical and surgical asepsis in healthcare practice protects patients from harmful pathogens, minimizes the risk of contamination of susceptible sites, and reduces the risk of infection transmission.

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

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.
