Healthcare Associated Infections II: Preventive Measures

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...

Hand hygiene

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.
Hand washing...

Standard Precaution

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...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

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. Common...

Infection

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...

Area of Science:

Infectious Diseases
Microbiology
Public Health

Background:

Healthcare-associated infections (HAIs) are a significant public health issue.
Healthcare workers (HCWs) play a crucial role in pathogen transmission.
Antimicrobial resistance necessitates novel prevention strategies.

Purpose of the Study:

To evaluate hand hygiene effectiveness among HCWs.
To correlate hand contamination with bloodstream infections.
To explore natural antimicrobial agents as complementary HAI prevention.

Main Methods:

Collected 128 hand samples from HCWs across different hospital units.
Quantified microbial load using Rodac TSA plates.
Identified isolates via MALDI-TOF and confirmed multidrug resistance using Phoenix BD system.
Tested susceptibility of isolates to natural antimicrobial agents.

Main Results:

Microbial growth detected in 54.7% of samples, predominantly coagulase-negative staphylococci and Enterobacteriaceae.
Identified potential overlapping pathogens between hand and blood cultures.
Thyme essential oil (Thymus vulgaris) showed significant antimicrobial activity.

Conclusions:

High standards of hand hygiene and device care are critical for HAI prevention.
Natural antimicrobial compounds, like thyme oil, can be effective adjuncts to hygiene protocols.
These agents may help combat infections caused by multidrug-resistant organisms.
