Overview
A thorough examination of the intrinsic and extrinsic factors that contribute to fall risk in older adults, and evidence-based strategies for addressing each.
Falls in older adults are rarely caused by a single factor. Instead, they result from a complex interplay of intrinsic factors (related to the individual) and extrinsic factors (related to the environment). Understanding both is essential for effective fall prevention.
Intrinsic factors include muscle weakness, balance impairments, vision problems, cognitive changes, and medication side effects. Many older adults have multiple intrinsic risk factors that compound their overall fall risk. A resident with mild balance issues might manage fine until a new medication causes dizziness.
Extrinsic factors encompass environmental hazards like poor lighting, slippery surfaces, cluttered walkways, and inappropriate footwear. While these factors are often easier to address than intrinsic factors, they're frequently overlooked in fall prevention programs.
Effective fall prevention requires addressing both categories of risk. This means regular medication reviews, strength and balance training, vision care, cognitive assessment, and systematic environmental modifications. Technology can help through regular smartphone-based assessments that surface changes in intrinsic factors and give staff fall-risk visibility so qualified teams can decide when intervention is needed.
Key Takeaways
- Falls result from multiple interacting risk factors
- Intrinsic factors include strength, balance, vision, cognition
- Extrinsic factors include environment and footwear
- Comprehensive programs address both categories
