“It happened so fast that I do not know how I fell.” This is a frequent refrain from those who fall, as falls does often occur without expectation. A fall is an unexpected event resulting in a person finding themselves on a lower supporting surface, either a chair or the floor.
Epidemiology of Falls
The number of falls in persons aged 65+, especially injurious or fatal ones, have risen sharply in recent years. One in four Americans aged 65+ falls each year1; if someone has fallen, their chance of falling again is doubled.2 One of five falls causes serious injury, so more than 3 million older people are treated in emergency departments for fall injuries each year.3
Hospitalizations of more than 800,000 patients were related to a fall-related injury4,5 with 300,00 related to hip fracture.6 One of every 200 falls results in hip fracture in the 65-69-year-old group with this rate increasing to 1 in 10 for those 85+ years old.
Deaths in older adults from falls increased 30% from 2007 to 2016, so that the anticipated mortality rate will be 7 fall deaths per hour by 2030. When assessing the very old (75+ years), analysis of US vital statistics demonstrated an increase in fatal falls from 8,600 in 2000 to 26,440 in 2017.
Falls among people with disability at younger and older ages are also a significant issue. Researchers noted that fall risk increases with the number of chronic conditions or co-morbidities, including arthritis, cancer, pulmonary disease, diabetes, depression, heart disease, hypertension, or stroke.7 Also, chronic diseases increase fall risk secondary to polypharmacy, limited activity, and changes in sensation and strength.
Adults aging with intellectual disability have fall rates three times higher than other elders.8 Their lower bone mineral density puts them at greater risk for fracture.9 Likewise, people with dementias and Alzheimer’s disease are twice as likely to fall,10 secondary to gait deficits and decline in postural control.11,12,13
People with multiple sclerosis demonstrated falls rates of > 50%,14,15 as do people diagnosed with Parkinson’s disease.16 People who have sustained a stroke also have a greater fall risk,17 most frequently when walking.18,19
While many falls do not result in injury, 47% of fallers cannot get up without assistance and spend some time immobile on the floor.
Cost of Falling
The cost of falls is enormous. Total medical costs totaled more than $50 billion in 2015 with Medicare and Medicaid funding 75% of these costs20; $12.5 billion were out-of-pocket expenses. Costs are expected to increase to $67.7 billion by 2020. Medical expenditures for women were two to three times higher than men.21 The personal cost of falls is also high, resulting in fear of falling with reduction in activity and loss of independence.
Why People Fall More Frequently as They Age
Decreases in strength, particularly lower extremity and core muscles, contribute. Loss of flexibility and endurance, as well as changes in vision, also impact fall risk. Less balance secondary to age-related changes as well as medications and vision can further increase fall risk. Foot pain or poor footwear can contribute to poor balance. Deficiency in Vitamin D is also a factor.
Where Falls Most Frequently Occur
Data from the 1997-1998 National Health Interview Survey show that 55% of fall injuries among older persons occur inside the house; 23% occurred outside the house and 22% happened away from home.22 In residences with no stairs, falls most frequently occurred in living rooms (31%), bedrooms (30%), kitchens (19%), bathrooms (13%), and hallways (10%) (Gill, 2000).
How to Lower Risk of or Prevent Falls
Falls are not an unavoidable consequence of aging. Risk assessment, lifestyle adjustments, and fall prevention programs and strategies can substantially decrease the risk of falling among both elders and persons with disability.
Fall Risk Assessment
Screening tools that can either be self-administered or provided by minimally trained medical staff can be utilized to assess fall risk. These tools, validated in broad populations, can identify low, moderate, or high fall risk. This risk assessment assists with definition of next steps, either simple home strategies, a fall prevention program, or further evaluation by primary practitioner or physical therapist. The most widely disseminated tool, developed by the Centers for Disease Control and Prevention (CDC), is “Stopping Elderly Accidents, Deaths and Injuries” (STEADI). This tool has been validated for community-dwelling elders who are ambulatory and able to respond to questions. Current research is now validating this tool with other populations of older persons (https://www.cdc.gov/steadi/index.html).
Elders who are independent can simply utilize the Stay Independent brochure developed by the CDC to self-assess their personal fall risks (https://www.cdc.gov/steadi/pdf/STEADI-Brochure-StayIndependent-508.pdf). This simple assessment will define not only risks but potential areas that need addressing such as strength, balance, medication review, incontinence, or depression.
Home Assessment
Simple home assessments can be self-administered, or provided by a friend, family member, or caregiver. Both tools below are available online at no cost and can guide a home assessment so that it is an orderly learning process.
The most available assessment is AARP Home Fit Guide (https://assets.aarp.org/www.aarp.org_/articles/families/HousingOptions/200590_HomeFit_rev011108.pdf). This free assessment evaluates both home livability and safety, and provides ideas for change and resources to accomplish these changes.
The other home assessment is Home Safety Self-Assessment Tool (HSSAT) developed by the University of Buffalo (https://sphhp.buffalo.edu/content/sphhp/rehabilitation-science/research-and-facilities/funded-research/aging/home-safety-self-assessment-tool/_jcr_content/par/download_526197706/file.res/HSSAT-v.5-1-12-17.pdf). This tool provides a room-by-room assessment with a tally of hazards, how-to instructions for improvement, and tips for fall prevention.
Standard and Simple
Many simple and inexpensive home modifications can be made by the individual or family. Among the guides to home modifications are two made available by the CDC: “Check for Safety: A Home Fall Prevention Checklist for Older Adults,” and “What You Can Do to Prevent Falls.” Both documents can be accessed online and are available for download as PDFs.

General modifications to increase safety would include:
1. Lighting
• Install lights on stairways both inside and out. Motion-sensitive lights will come on when someone is on the stairs, saving on electricity. If switch operated, glow-in-the-dark switches should be installed on the top and bottom of the steps.
• Make home lighting brighter with bulbs that do not add glare.
• Place LED nightlights in hallways, bedrooms, and bathrooms.
• Position a lamp within arm’s reach of the bed for use at night.
• Store flashlights in defined places in case of power outages. Purchase several battery back-up lights in critical places like the bedroom and bath.
2. Stairs
• Install at least one railing on each stairway.
• If stairs are not carpeted, add nonslip treads to wooden stairs.
3. Bathroom
• Install grab bars strategically by the toilet and inside and outside the shower or tub.
• Place non-slip mats or strips on the floor of the shower or tub.
• Position rugs with non-slip backs outside the tub to keep the floor dry.
• Consider using a tub chair with a back if balance, strength, or dizziness are issues.
4. Floors
• Remove all throw rugs from the floors.
• Use two-sided carpet tape, non-slip backing or tacks on any remaining rugs.
• Repair any loose carpeting or floorboards.
• Consider painting door sills a different brighter color to avoid tripping.
• Immediately clean any spilled liquids or food.
5. Clutter
• Remove obstacles both inside and outside of the house that might cause tripping.
• Declutter the main living areas so that they are easy to navigate.
• Tie up or stash cords to lights and computers so they cannot be tripped on.
• Keep pet toys off to the side, not in the main walking areas.
6. Clothing
• Wear sensible sturdy shoes that fit properly and cover the heel of the foot.
• Assure that all shoes have non-skid soles.
• Wear clothing that is not overly blousy or easy to entangle oneself.
7. Room arrangement
• Reassess the location of your dishes, food, and cooking items in the kitchen. and store them within easy reach.
• Reassess the location of clothing in drawers and closets so it is easily reachable.
• Place shoes on a shoe rack that is elevated to eliminate bending over.
• Position chairs for sitting to dress, if needed.
• Position a chair by the washer/dryer so you can sit while you do laundry.
8. Safety Devices
• Use an assistive device if needed and recommended by a healthcare practitioner. This might be a cane or walker as indicated.
• Consider use of a Personal Emergency Response System (PERS) that you can use to alert others if you fall or need assistance.
9. General Medical
• Have your vision checked regularly every year.
• Keep glasses handy on a neck chain.
• Attempt to do some regular exercise, either at home or in a class (tai chi or yoga)
• Ask your doctor to review your medications regularly for side effects and interactions.
• Note new symptoms when walking or moving, such as dizziness, numbness, or shortness of breath. Tell your healthcare practitioner so he/she can evaluate.
Targeted
Targeted modifications are changes more specific to the individual situation that may have additional cost. For example, if a person uses a walker or wheelchair, doorways might be too narrow. So, either key doorways will need to be widened, or a special narrow device will need to be ordered. If an individual resides in a location that has snow and ice in the winter, they need to consider the use of a device like YakTraks so they will be able to walk safely outside. Likewise, electric heated mats for steps and entrances melt the ice and snow.
Costly and Complex
Occasionally, the reduction of fall risk necessitates more costly and complex modifications. The cost is worth the risk reduction and can often be partially covered by insurance.
The first example of a more expensive and complicated modification might be a ramp. Sometimes, stairs are just too dangerous or not navigable, so consideration of a ramp is a much safer alternative. Ramps can be portable and purchased or built to be more permanent. The angle of the ramp is important, so specifications for ramps can be found online at https://baileylineroad.com/wheelchair-ramp-building-plans/
Another example of a more costly protection might be a lift. If an individual has significant difficulty getting into and out of bed, chairs and shower, then consideration of a lift is a safety precaution for both person and caregiver. Several types of home portable lifts are available for consideration. Several lifts permit the patient to bear weight on the foot with knees supported as they stand and transfer. Other lifts have an overhead bar that allows the patient to be lifted entirely in a sling for transfer. Finally, ceiling lifts can be installed over beds or tubs for lifing from chair to surface.
A stair lift might be another mobility consideration. Many individuals live in homes with stairs in which they wish to remain. However, their disability or age make these areas of the home either unsafe to access or inaccessible. The development of installable seated chair lifts for straight and curved stairways has provided a safe solution. Stair climbers also exist for moving a wheelchair up and down stairs both inside and out.
Finally, transportation solutions have also assisted elders and persons with disability to travel. Lifts for cars and trucks permit transportation of wheelchairs and scooters. Rotating swivel seat platforms make entrance and exit from a car seat easier, as do car transfer aids and bars. Turning automotive seats are the next level of easier and safer ingress and egress from vehicles and perhaps into a wheelchair. RM
