A Multifactorial Problem: Intrinsic, Extrinsic, and Situational Causes
When attempting to answer what is the main reason residents fall, it is more accurate to view it as a puzzle with many pieces. Experts categorize these risk factors into three main areas: intrinsic, extrinsic, and situational. A resident's risk of falling increases exponentially when factors from multiple categories are present at once, highlighting the importance of a holistic prevention strategy.
Intrinsic Factors: Internal Health and Body Changes
Intrinsic factors are internal issues related to a resident's physical and mental health. These are often the most significant contributors to fall risk and can include age-related decline, balance and gait problems (such as those caused by arthritis or Parkinson's disease), medication side effects, vision and hearing impairment, cognitive issues, and chronic health conditions. Lower body weakness and insufficient Vitamin D levels are also common intrinsic causes.
Extrinsic Factors: Environmental Hazards in the Living Space
Extrinsic factors refer to external hazards within a resident's environment. While these can seem more manageable than intrinsic issues, they are often overlooked. Common examples in a residential setting include poor lighting, clutter and obstacles in pathways, slippery or uneven floors, lack of safety equipment like grab bars, and inappropriate footwear.
Situational Factors: Specific Triggers
Situational factors are triggers related to a specific activity or circumstance that increase the risk of a fall. These can include rushing to the bathroom at night, especially when affected by medication, or hurrying to answer a phone. Additionally, experiencing a fall can lead to a fear of falling, causing reduced physical activity and subsequent muscle weakness, which paradoxically increases future fall risk.
Intrinsic vs. Extrinsic Risk Factors: A Comparison
To highlight the difference in fall risk management, the following table compares typical intrinsic and extrinsic risk factors found in long-term care settings.
| Factor Category | Common Examples | Management Strategy |
|---|---|---|
| Intrinsic | Lower body weakness, medication side effects, poor balance, cognitive impairment. | Individualized care plans, regular medication reviews, physical and occupational therapy, vision/hearing screenings. |
| Extrinsic | Clutter, poor lighting, wet floors, lack of grab bars, inappropriate footwear. | Environmental safety audits, staff training on fall hazards, modifying the living space with safety equipment, promoting proper footwear. |
Implementing a Comprehensive Fall Prevention Plan
Effective fall prevention goes beyond simply addressing one or two issues; it requires a systematic, multi-pronged approach involving an interdisciplinary team. Key components include regular risk assessments (especially for those over 65), environmental modifications, physical activity programs focused on strength and balance, medication management, staff training on fall risk factors, and training residents on proper use of assistive devices.
Conclusion
There is no single cause to answer what is the main reason residents fall. Instead, falls are typically the result of intrinsic, extrinsic, and situational factors interacting. Common intrinsic factors include lower body weakness and balance issues, often compounded by extrinsic hazards like poor lighting. A comprehensive, individualized prevention program is the most effective way to reduce fall incidence by addressing these multiple risk areas simultaneously.

Understanding and Preventing Falls in Senior Care
Multifactorial Risks: The main reason residents fall is typically not a single issue, but a combination of intrinsic (internal health) and extrinsic (environmental) factors.
Leading Intrinsic Causes: Common health-related causes include muscle weakness, balance and gait problems, certain medications, and vision impairments.
Key Environmental Hazards: Extrinsic risks often involve poor lighting, cluttered living spaces, slippery floors, and lack of safety features like grab bars.
Impact of Medications: Polypharmacy, or taking multiple medications, is a significant risk factor due to potential side effects like dizziness and confusion.
Prevention Strategies: Effective fall prevention requires a comprehensive approach, including regular risk assessments, environmental modifications, exercise programs, and medication reviews.
Addressing Fear of Falling: A previous fall can lead to a fear of falling, causing reduced activity and further muscle weakness, thereby increasing future risk.
Individualized Care: Creating personalized care plans that address specific resident needs and risk factors is more effective than a one-size-fits-all approach.
