Chronic Lower Limb Oedema in Older Adults:
Why Screening Matters

By AAG member: Maree O'Connor

 

Chronic lower limb oedema, or long-term swelling in the feet and legs, is a common issue among older adults living in the community, as highlighted by a new Australian study. It can lead to serious complications like wounds, infections (such as cellulitis), and a reduced quality of life. Early detection and management are critical to preventing these outcomes.

What is Chronic Oedema?
Chronic oedema refers to swelling that lasts for more than three months, often affecting both legs. This occurs when fluid builds up in the tissues. This condition can significantly affect health, mobility, and independence while increasing the risk of complications like wounds and infections.

This study, the largest of its kind in Australia, found that 38.1% of older adults receiving home care had chronic oedema. With 459 participants, it highlights how common this condition is and the need for routine screening.

Who is at Risk?
Certain groups are more likely to develop chronic oedema:

  • Heart Conditions: Chronic heart failure and ischaemic heart disease significantly increase the risk, with heart failure raising the odds by 3.7 times.
  • Reduced Mobility: Using a mobility aid was strongly linked to oedema, potentially due to decreased physical activity or reduced calf muscle efficiency.
  • Age: The risk increases with age.

Interestingly, the study found that dementia was associated with a lower risk of oedema, possibly because increased movement, such as wandering, may promote better circulation.

Why Screen for Oedema?

Routine screening is crucial for early detection and timely treatment. The study showed that non-health professionals, like case managers, can perform screenings using simple tools. For example, the pitting test involves pressing on the top of the foot or behind the ankle bones to check for swelling. This quick and easy method makes screening accessible, even in areas where healthcare professionals are limited.

Managing Oedema
Early intervention can reduce the risk of complications. Strategies include:

  • Compression therapy to improve circulation and lymphatic drainage.
  • Encouraging physical activity to activate the muscle pump, which helps reduce oedema.
  • Addressing underlying conditions, such as heart failure or obesity.

Call to Action
Routine screening for chronic lower limb oedema should be a priority, especially for older adults with heart conditions or mobility issues. This study highlights that non-health professionals, with proper training, can play a critical role in identifying chronic oedema.

March is Lymphoedema Awareness Month, a time to promote the importance of screening and early management. Organisations like the Lymphoedema Association Australia led efforts to raise awareness. They will be shining a light on lymphoedema by lighting up buildings, sculptures and landmarks. Visit their Awareness Campaign to learn more or get involved. 

The Australasian Lymphology Association has a register of accredited lymphoedema practitioners. Consumers, carers, and referrers can be assured they will receive the best advice and care for chronic oedema.

By incorporating routine screening into aged care services, we can prevent complications, enhance independence, and improve the quality of life for older adults. Early detection makes all the difference.
