Summer Infections In Aged Care

Summer is often associated with warmth, sunshine, and outdoor activities. However, for those in aged care settings, it can also bring a heightened risk of infections. While we enjoy the longer days and social gatherings, it’s crucial to recognise that the warmer months can create conditions where infections spread more easily in an aged care facility. This post aims to highlight these hidden risks and provide practical advice on how to keep our loved ones safe this summer. We'll explore the specific challenges of summer infections in aged care, focusing on infection prevention strategies that you could implement to make a real difference.

Several factors contribute to the increased risk of infections in aged care during the summer.

Vulnerable Populations = Weakened immune systems: common in older adults making them more susceptible to infections or eliciting more serious complications. Chronic illnesses and some medications can weaken an already compromised immune response.

Close proximity in aged care facilities facilitates the rapid spread of infections.

Environmental Factors

• Increased social interactions during summer can contribute to higher risks of infection susceptibility.
• Summer heat, humidity and dehydration can exacerbate underlying health issues, making residents adults more vulnerable to infections. Heat and humidity can also be the ideal conditions for some infections. For example, respiratory conditions can worsen, skin conditions may be more prevalent, and dehydration can increase the risk of urinary tract infections (UTIs). Food safety is also an issue, leading to an increase in gastrointestinal infections.

Several infections are more prevalent in aged care during the summer months.

• Gastrointestinal Infections
  These are highly contagious and can cause severe dehydration and electrolyte imbalance in older adults. Common culprits include norovirus, rotavirus, and Salmonella. These infections are often spread through contact with infected individuals, contaminated surfaces, or food.
• Respiratory Infections
  Though more often associated with winter, respiratory infections like pneumonia can occur year-round. Summer heat can worsen existing respiratory conditions. These infections spread through respiratory droplets produced when coughing and sneezing.
• Urinary Tract Infections (UTIs)
  UTIs are common in older adults, particularly women. Dehydration, often more common in the heat, can increase the risk of UTIs.
• Skin Infections
  These become more prevalent in the summer due to a warm and moist environment that favours the growth of bacteria and fungi, especially in skin folds or areas not exposed to the air. Skin infections can manifest as rashes, cellulitis, and fungal infections.

Recognising these common infections and their transmission methods is the first step in implementing effective prevention strategies.

Implementing robust infection prevention and control measures is essential in reducing the spread of infections in aged care facilities.

Standard Precautions: must always be implemented in aged care facilities, and include the following:

• Hand hygiene is one of the most effective interventions to reduce the risk of infections. This includes regular handwashing with soap and water or using alcohol-based hand rubs, especially before and after contact with residents.
• Personal protective equipment (PPE), used appropriately, is crucial when providing personal care or handling potentially contaminated materials.

Environmental cleaning: also plays a key role in preventing infections. Regular cleaning, with detergent, of surfaces, shared equipment, and common areas can significantly reduce the transmission of microorganisms. Disinfection of the same is essential in an outbreak situation. Particular attention should be given to areas where gastrointestinal infections are easily spread. In residential care, surfaces should be cleaned with a detergent solution and a hospital-grade disinfectant. In home-care settings, aged care workers should communicate with their clients to discuss appropriate cleaning and disinfection practices.

Transmission-based precautions: are used in addition to standard precautions based on how an infection is spread. For example, contact precautions would be used when caring for a resident with a gastrointestinal infection, and respiratory precautions would be used when a resident has a respiratory infection. For respiratory infections, a surgical mask with eye protection is recommended. In higher-risk situations, a particulate filter respirator (N2 or P95) may be more appropriate.

Specific Infection Control Measures in Aged Care: Infection control in aged care is crucial in providing safe care to residents, their families, visitors and staff. Everyone in an aged care setting has a role in preventing and controlling infections in an aged care facility.

Aged care facilities must adhere to stringent guidelines and aged care standards in infection control to prevent outbreaks. These standards emphasise the need for a structured approach to infection control in aged care, which includes regular risk assessments, training, and the development of local policies and procedures.

Policies and Legislation: Facilities should have clear infection control policies, detailing procedures for managing infectious diseases, hygiene practices, and outbreak response. These policies should align with infection control legislation in aged care. For example, providers must act fast to control the spread of infection and notify their state or territory health department of outbreaks.

As we've explored, summer can bring heightened risks of infection for older adults in aged care settings. Gastrointestinal, respiratory, and urinary tract infections, as well as skin infections, pose significant challenges that can be addressed through diligent prevention and control strategies. By implementing standard and transmission-based precautions, promoting vaccinations, and adhering to stringent infection control policies, facilities can create a safer environment for their residents. Remember, a multi-faceted approach involving robust infection prevention and control systems, that are regularly audited and improved, is essential for protecting our seniors. What proactive steps will you take this summer to ensure the well-being of our vulnerable elders?

To further your understanding and commitment to better practices, we encourage you to delve into the Aged Care Infection Prevention and Control Guide for detailed protocols, explore the Australian Immunisation Handbook for the latest guidelines, and participate in initiatives like the National Antimicrobial Prescribing Survey (AC NAPS) to collectively enhance infection prevention in aged care. Continue the conversation by sharing your experiences and insights in the comments below or explore our related posts for more practical advice and resources on this important issue.

For Aged Care Providers and Staff: Download the Aged Care Infection Prevention and Control Guide to review and update your facility's policies and procedures. Ensure all staff complete necessary infection control aged care modules to enhance their skills and knowledge.

For Family Members and Visitors: Stay informed about infection prevention measures. Always practice thorough hand hygiene when visiting, and do not visit if you are unwell. Ask the facility about their policies and how you can help support infection control.

For Everyone: Share this post with your network to raise awareness about summer infections in aged care. Let’s work together to protect our most vulnerable. Consider participating in the National Antimicrobial Prescribing Survey (AC NAPS)37... to further contribute to infection prevention.
