Methods to Reduce Healthcare-Associated Infections for High Asepsis Score
Hand hygiene and proper use of personal protective equipment are the most fundamental and effective methods to reduce healthcare-associated infections and achieve a high asepsis score. 1
Hand Hygiene
- Decontaminate hands by washing with antimicrobial soap and water or using alcohol-based waterless antiseptic agents when hands are not visibly soiled 1
- Perform hand hygiene before and after contact with patients, especially those with invasive devices 1
- Perform hand hygiene after handling respiratory secretions or objects contaminated with secretions 1
- Decontaminate hands between contacts with different patients and between contacts with a contaminated body site and the respiratory tract 1
Personal Protective Equipment (PPE)
- Wear gloves when handling respiratory secretions or objects contaminated with respiratory secretions 1
- Change gloves between contacts with different patients 1
- Change gloves after handling respiratory secretions before contact with another patient, object, or environmental surface 1
- Wear gowns when soiling with respiratory secretions is anticipated 1
- Change gowns after soiling occurs and before providing care to another patient 1
Aseptic Technique for Procedures
- Perform invasive procedures (e.g., tracheostomy) under strict aseptic conditions 1
- When changing tracheostomy tubes:
- Wear a gown
- Use aseptic technique
- Replace the tube with one that has undergone sterilization or high-level disinfection 1
- For suctioning of respiratory tract secretions:
Equipment Sterilization and Disinfection
- Change the mouthpiece of peak flow meters or the mouthpiece and filter of spirometers between uses on different patients 1
- Avoid using large-volume room-air humidifiers that create aerosols unless they can be sterilized or subjected to high-level disinfection daily 1
- Use only sterile water in humidifiers 1
- Apply chlorhexidine gluconate for oral decontamination to reduce the risk of ventilator-associated pneumonia 2, 3
Environmental Controls
- Maintain a clean surgical environment 4
- Remove faucet aerators in units where immunocompromised patients are treated if Legionella species are detected 1
- Implement selective oral decontamination and selective digestive decontamination to reduce ventilator-associated pneumonia 1
Nursing Interventions
- Practice and promote hand hygiene consistently 1
- Use standard precautions consistently 1
- Ensure proper cleaning and disinfection practices 1
- Remove unnecessary invasive devices promptly 1
- Implement bundle strategies for infection prevention 1
- Place patients in semi-recumbent position (head of bed elevated 30-45°) to prevent ventilator-associated pneumonia 2
Antibiotic Stewardship
- Avoid prolonging antibiotic prophylaxis after surgery, as it is generally not associated with better clinical outcomes 1
- De-escalate to the most appropriate single therapy as soon as the susceptibility profile is known 1
- Administer effective intravenous antibiotics within the first hour of sepsis recognition 2
Patient Education
- Implement educational and training interventions concerning the prevention of surgical site infections 1
- Ensure patients are effectively educated throughout their hospitalization to prepare them for self-care 1
Common Pitfalls and Caveats
- Failure to change gloves between patients is a common breach of aseptic technique 5
- Confusion between "clean," "aseptic," or "sterile" technique can lead to improper practices, especially in home healthcare settings 6
- Lack of competency-based training that doesn't reflect the critical importance of aseptic technique to patient safety 6
- Failure to recognize when aseptic technique has been breached and not taking immediate corrective action 7
- Underestimating the importance of proper hand hygiene as the most fundamental infection prevention measure 1
By implementing these evidence-based practices systematically, healthcare facilities can significantly reduce healthcare-associated infections and achieve high asepsis scores, ultimately improving patient outcomes and reducing morbidity and mortality.
