An Overview of Infections and Infection Prevention in Long-Term Care Facilities

In long-term care (LTC) facilities, the well-being of residents relies on the effectiveness of infection prevention measures. Given the vulnerability of this population—often elderly individuals with multiple chronic conditions—understanding the nature of common infections and implementing robust prevention strategies is important.

Infection prevention refers to the application of policies, procedures, and practices designed to minimize the risk of infections, particularly in healthcare settings like LTC facilities. Qsource helps facilities understand the importance of establishing robust infection prevention strategies and can directly assist your facility to implement a comprehensive plan of action.

The goal is to protect both residents and healthcare workers from infectious diseases, thereby ensuring a safe and healthy environment. Infection prevention encompasses a broad range of activities aimed at breaking the chain of infection, which involves preventing the transmission of pathogens from one person or place to another.

Common Infections in LTC Facilities

Respiratory Infections:

• Influenza: Seasonal outbreaks can cause severe illness and complications in LTC residents. Vaccination is key, alongside prompt antiviral treatment.
• Pneumonia: Often bacterial, pneumonia can follow viral infections or result from aspiration. Pneumococcal vaccination is essential.
• COVID-19: The ongoing pandemic has highlighted the critical need for rapid identification, isolation, and management of cases to prevent widespread transmission.

Urinary Tract Infections (UTIs):

• Common due to factors like catheter use, decreased mobility, and poor fluid intake. UTIs can lead to serious complications like urosepsis if untreated.

Gastrointestinal Infections:

• Norovirus: Highly contagious, leading to vomiting and diarrhea. Strict hygiene and isolation are crucial during outbreaks.
• Clostridium difficile: Often linked to antibiotic use, causing severe diarrhea and colitis. Managing antibiotic use and maintaining hygiene can help prevent its spread.

Skin and Soft Tissue Infections:

• Pressure Ulcers: Result from prolonged immobility. Regular repositioning and skin care are preventive measures.
• Cellulitis: Bacterial infection of the skin, often starting from minor injuries. Early treatment is important to prevent complications.
• Scabies: Caused by mites, leading to intense itching and skin rash. Quick isolation and treatment can prevent outbreaks.

Modes of Transmission

Understanding transmission pathways is essential for effective infection control. Key modes include:

• Direct Contact: Transmission through physical contact, including handshakes or caregiving activities.
• Indirect Contact: Involves touching contaminated surfaces or objects.
• Droplet Transmission: Spread through respiratory droplets from coughing or sneezing. These droplets can travel short distances and land on mucous membranes.
• Airborne Transmission: Involves smaller particles that can remain suspended in the air and be inhaled, relevant for diseases like tuberculosis and COVID-19.
• Fecal-Oral Route: Pathogens transmitted through ingestion of contaminated food, water, or via hand-to-mouth contact after touching contaminated surfaces.

Key Infection Prevention Strategies

Hand Hygiene: Regular and thorough handwashing with soap and water or using alcohol-based hand sanitizers. Hand hygiene should be performed before and after resident contact, after touching potentially contaminated surfaces, and before handling food or medications.

Personal Protective Equipment (PPE): Proper and consistent use of PPE, including gloves, gowns, masks, and eye protection. Training staff on correct donning and doffing procedures is crucial to avoid contamination.

Environmental Cleaning and Disinfection: Regular cleaning schedules for high-touch surfaces (e.g., doorknobs, light switches, handrails) and thorough disinfection of resident rooms and communal areas. Use EPA-approved disinfectants known to be effective against the relevant pathogens.

Vaccination: Keeping residents and staff up-to-date with essential vaccines, including those for influenza, pneumococcal disease, and COVID-19. Annual flu vaccination campaigns and ensuring new residents and staff are vaccinated upon entry.

Antimicrobial Stewardship: Promoting the use of antibiotics to prevent the emergence of antibiotic-resistant bacteria. Implementing protocols for appropriate antibiotic prescribing and monitoring antibiotic use.

Education and Training: Continuous education of staff on infection control protocols, including hand hygiene, PPE use, and identifying signs of infection. Regular training sessions and updates on best practices and new guidelines.

Isolation Precautions: Implementing contact, droplet, or airborne precautions for residents with confirmed or suspected infections. Clear signage and dedicated equipment for isolated residents can help prevent cross-contamination.

Resident and Staff Screening: Regular health screenings for residents and staff to promptly identify and isolate infected individuals. This includes temperature checks, symptom monitoring, and testing as necessary.

Role of Nursing Home Staff

Nursing home staff are the front-line defenders against infections. Their responsibilities include:

• Monitoring Residents: Vigilantly assessing residents for early signs of infection, such as fever, cough, or changes in behavior. Timely medical evaluation and treatment can prevent the escalation of infections.
• Adhering to Protocols: Strictly following established infection control procedures. Consistent adherence reduces the risk of transmission and enhances overall facility safety.
• Communication: Maintaining open lines of communication among staff, residents, and families. Providing clear information about infection risks, prevention measures, and outbreak management can foster cooperation and compliance.
• Leading by Example: Demonstrating good infection control practices to encourage others to follow suit. Staff behavior significantly influences the overall culture of hygiene and safety within the facility.

Additional Considerations

Outbreak Management: Having a robust outbreak management plan in place is critical. This includes immediate isolation of affected individuals, increased cleaning frequency, and communication with public health authorities.

Visitor Policies: Implementing and enforcing visitor policies to minimize infection risk. During outbreaks, restricting visitors or screening them can be necessary to protect residents.

Nutrition and Hydration: Ensuring residents receive adequate nutrition and hydration supports their immune systems, making them less susceptible to infections.

Mental Health Support: Recognizing the impact of infection control measures on residents' mental health. Providing support and maintaining social interactions, even if modified for safety, can help mitigate feelings of isolation. 

Infection prevention in long-term care facilities is a multifaceted endeavor requiring diligence, knowledge, and collaboration. By understanding the common infections, their transmission modes, and implementing comprehensive prevention strategies, nursing home staff can significantly reduce the risk of infections.

Continuous education, proper use of PPE, environmental hygiene, and vaccination are the cornerstones of an effective infection control program. With these measures in place, LTC facilities can create a safer environment and enhance the quality of life for their residents, ensuring that they receive the compassionate and safe care they deserve.
