When someone falls over. Durr. More specifically, when they fall over, and get some kind of pathology resulting from that.
There are a variety of factors which can increase risk. The following are broadly speaking the groups in which to these risk factors can categorised:
- Muscle weakness
- Gait deficit
- Mobility limitiation
- Visual impairment
- Balance deficit (including dizziness)
- Cognitive impairment
- Consciousness impairment (sudden or gradual)
- Psychotropic medication - benzodiazepines, antidepressants and antipsychotics
- BP lowering drugs
These can be attributed as direct causes of falls but there are other factors which increase risk without being direct causally linked:
- Comorbid conditions
- PMHx: history of fall in the last year
- Age (<80 years)
- Use of assistive device i.e. walking stick
Falling over is really the key manifestation of falling.
- neurological problems: such as MS, or Parkinson's, both of which can present with mobility problems.
- alcohol abuse
- cardiac arrhythmias
- impaired vision
According to this study, if someone has a fall, their risk of hospitalisation increases significantly. With that hospitalisation, there is an increased risk of death in the next year.
However, if someone falls and doesn't require hospitalisation, their risk of death is not affected, unless they fall a lot.
