Healthcare Associated Infections II: Preventive Measures

3.2K
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 hygiene01:23

Hand hygiene

4.6K
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.

Antimicrobial Effectiveness01:28

Antimicrobial Effectiveness

506
The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

12.8K
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...

Documentation in long-term care facilities and home healthcare settings is crucial for ensuring continuous, coordinated, and comprehensive care for patients. Each setting has its specific documentation processes and tools:

Surface Membrane Barriers01:18

Surface Membrane Barriers

1.7K
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Area of Science:

  • Infectious Diseases
  • Public Health
  • Epidemiology

Background:

  • Recurrent skin and soft tissue infections (SSTIs) caused by Community-Associated Methicillin-Resistant Staphylococcus aureus (CA-MRSA) and Methicillin-Sensitive Staphylococcus aureus (CA-MSSA) pose significant treatment challenges.
  • Effective strategies are needed to reduce SSTI recurrence and prevent household transmission.

Purpose of the Study:

  • To evaluate an evidence-based intervention aimed at reducing recurrent SSTIs.
  • To assess the intervention's impact on household contamination, transmission, and patient-reported outcomes.

Main Methods:

  • A community-based trial involving 186 participants with confirmed SSTIs and their households.
  • The experimental group received hygiene education, topical decolonization (mupirocin, chlorhexidine), and surface decontamination wipes.
  • The control group received usual care pamphlets. Outcomes were assessed via electronic health records, home visits, telephone assessments, and surveillance cultures over six months.

Main Results:

  • No significant difference in SSTI recurrence was observed between the experimental and control groups.
  • The intervention group showed non-significant reductions in colonization rates.
  • No significant differences were found in household member transmission, surface contamination, or patient-reported outcomes.

Conclusions:

  • The tested intervention, delivered by community health workers, did not effectively reduce clinician-reported SSTI recurrence.
  • Future research should explore longer or repetitive decolonization protocols delivered via community health worker interventions.
