Medical Compass: Reduce your risk of falling with simple strategies

Some medication side-effects include increased fall risk

By David Dunaief, M.D.

This has been a particularly challenging winter here in the Northeast. Instead of snow, we’ve had a fair amount of ice and variable temperatures that caused snowy surfaces to ice over.

Many older adults are concerned about falling, thus they stayed inside and sedentary. While this addressed the immediate challenge of icy sidewalks, it may have increased their risk of falling in the future.

What drives this concern about falls? Even without icy steps and walkways, falls can be serious for older patients, where the consequences can be devastating. They can include brain injuries, hip fractures, a decrease in functional ability and a decline in physical and social activities (1). Ultimately, a fall can lead to loss of independence (2).

There are many factors. A personal history of falling in the recent past is the most prevalent. However, there are other significant factors, such as age and medication use. Some medications, like antihypertensive medications, which are used to treat high blood pressure, and psychotropic medications, which are used to treat anxiety, depression and insomnia, are of particular concern. Chronic diseases can also contribute.

Circumstances that predispose us to falls also involve weakness in upper and lower body strength, decreased vision, hearing disorders and psychological issues, such as anxiety and depression (3).

Setting yourself up for success

Of the utmost importance is exercise. But what do we mean by “exercise”? We mean exercises involving balance, strength, movement, flexibility and endurance, all of which play significant roles in fall prevention (4). The good news is that many of these can be done inside with no equipment or with items found around the home.

Footwear also needs to be addressed. Nonslip shoes are crucial indoors, and footwear that prevents sliding on ice in winter, such as slip-on ice cleats that fit over your shoes, is a must. In the home, inexpensive changes, like securing area rugs and removing other tripping hazards, can also make a big difference.

Does medication increase risk?

There are a number of medications that may heighten fall risk. As I mentioned, psychotropic drugs top the list. But what other drugs might have an impact?

High blood pressure medications have been investigated. A well-designed study showed an increase in fall risk in those who were taking high blood pressure medication (5). Those on moderate doses of blood pressure medication had the greatest risk of serious injuries from falls, a 40 percent increase.

Blood pressure medications have significant benefits in reducing the risks of cardiovascular disease and events. Thus, we need to weigh the risk-benefit ratio in older patients before stopping a medication. We also should consider whether lifestyle modifications, which play a significant role in treating this disease, can be substituted for medication (6).

The value of exercise

A meta-analysis showed that exercise significantly reduced the risk of a fall (7). It led to a 37 percent reduction in falls that resulted in injury and a 30 percent reduction in falls requiring medical attention. Even more impressive was a 61 percent reduction in fracture risk.

Remember, the lower the fracture risk, the more likely you are to remain physically independent. The author summarized that exercise not only helps to prevent falls but also fall injuries.

Unfortunately, those who have fallen before, even without injury, often develop a fear that causes them to limit their activities. This leads to a dangerous cycle of reduced balance and increased gait disorders, ultimately resulting in an increased risk of falling (8).

What types of exercise help?

Any consistent exercise program that improves balance, flexibility, and muscle tone and includes core strengthening should help you improve your balance. Among those that have been studied, tai chi, yoga and aquatic exercise have all been shown to have benefits in preventing falls and injuries from falls.

A randomized controlled trial showed that those who did an aquatic exercise program had a significant improvement in the risk of falls (9). The aim of the aquatic exercise was to improve balance, strength and mobility. Results showed a reduction in the overall number of falls and a 44 percent decline in the number of exercising patients who fell during the six-month trial, with no change in the control group.

If you don’t have a pool available, tai chi, which requires no equipment, was also shown to reduce both fall risk and fear of falling in older adults (10).

Another pilot study used modified chair yoga classes with a small assisted living population (11). Participants were those over 65 who had experienced a recent fall and had a resulting fear of falling. While the intention was to assess exercise safety, researchers found that participants had less reliance on assistive devices and three of the 16 participants were able to eliminate their use of mobility assistance devices.

Thus, our best line of defense against fall risk is prevention with exercise and reducing slipping opportunities. Should you stop medications? Not necessarily. But for those 65 and older, or for those who have arthritis and are at least 45 years old, it may mean reviewing your medication list with your doctor. Before you consider changing your blood pressure medications, review your risk-to-benefit ratio with your physician.
