Complications of Immobility in the Elderly

Immobility in hospitalised elderly patients can lead to many complications and challenges. For example, it is known that older patients who are immobile are more likely to lose some of their capacity to perform activities of daily living during their stay in hospital.1,2

Management of immobility in the elderly hospital population is key in ensuring they don’t suffer from loss of muscle mass and strength (deconditioning), leading to greater physical dependency. Deconditioning is one of the most common reasons for prolonged length of stay in hospitals.3

In addition to deconditioning, prolonged immobility is associated with increased fatigue, low self-esteem and loss of confidence. This can increase the risk of falls and the development of pressure ulcers.4,5

Mobility is important because it helps to maintain health and the body’s ability to heal and repair. When in-patients are immobile, every body system is adversely affected. This can result in severe complications including:6

  • Dehydration, resulting in fluid and electrolyte imbalance
  • Increased blood viscosity, which increases the risk of DVT / PE development
  • Cardiac deconditioning
  • Respiratory infections
  • Musculoskeletal deconditioning and contractures
  • Constipation
  • Urinary tract stasis and infection
  • Pressure ulcers
  • Anxiety and depression

Research has shown that a length of stay in hospital over 10 days can lead to 10 years of muscle ageing for patients who are aged over 80 years.7 The research also showed that 35% of 70-year-old in-patients experience functional decline during their hospital admission in comparison with their pre-illness baseline. For people aged over 90 this increases to 65%.8

It is clear that early mobilisation is a crucial factor in reducing the risk of these complications associated with immobility and should form a key part of the patient’s care plan. Early mobilisation helps to reduce the length of hospital stay, achieving a more positive patient outcome and reducing costs.
