Unfortunately, falls with serious injury are consistently among the top ten reported sentinel events. Falls are also preventable. Let's start with some common information about falls: - Mental status and medications are the most significant risk factors for falls. - Falls are common among the elderly, with more than 30% of people 65 and older falling unintentionally. - Head trauma, fractures (including hip), and soft tissue injuries are potential outcomes of patient falls. - Falls can also be fatal. If they aren't fatal, they can lead to permanent disability, a decrease in physical function, and a reduced quality of life. - Falls can also lead to a lose of confidence and an inhibiting fear of falling. These feelings can then lead to further physical decline, depression, feelings of helplessness, and social isolation. - Most falls occur from or near the bed. All patients should be assessed for fall risk: - Ask patients about their fall history. If they have fallen in the past, ask for as much information as possible about the fall. Identifying a pattern can help prevent future falls. Always review the patient's medication list. - Strength, range of motion, pain, posture, and muscle tone should all be assessed. - Objective tests, such as a functional mobility tests and functional gait tests, can help assess a patient's fall risk. A physical therapy consult is usually ideal to evaluate the above mentioned functional mobility and gait tests. However, most tasks can be assessed with close observation and evaluation. -Functional mobility tests rate a patient's ability to do certain tasks, such as sitting or standing unsupported, standing up from sitting, standing with eyes closed, turning, reaching, retrieving an item from the floor, transferring (for example, from chair to bed), and climbing stairs. - Functional gait tests rate the patient's ability to walk. These tests look at how far and how long the patient can walk, how often the patient stops when walking, length and height of the patient's steps, how often and how far the patient strays from a straight path and how much the upper body sways when the patient walks. When indicated, patients should have routine physical therapy to help improve strength and endurance, correct gait and/or balance abnormalities, and improve range of motion. Hospitals should implement fall prevention programs and evaluate the results of such programs. At risk patients and their families should be educated about the risk of falls during hospitalization. They should be taught basic strategies for minimizing risk such as changing position slowly and calling for help. Patients who call for help have fewer falls than those who do not. Reorient confused patients and ask family members to stay with the patient if they can. Confused patients are also best in low beds and near the nurses' station. Unfortunately, with the COVID-19 pandemic and the decreased visitation allowed in many hospitals, the risk of falls in confused patients is much greater. Bed alarms are helpful to alert staff when a patient starts to leave bed. Bed rails and other restraints are sometimes put in place to prevent falls however restraints do NOT reduce the risk of falls and fall-related injuries. In fact, restraints may actually increase fall-related injury and death secondary to limited movement, which leads to muscle weakness and reduced physical function. One routine activity that can play a huge role in patient falls is needing to go to the bathroom. Patients, confused or not, that experience incontinence, urgency or diarrhea, should be checked on and taken to the toilet regularly. This of course also includes patients on laxatives and diuretics (water pills). Hourly rounding is a major standard intervention in most hospitals to help with just this and therefore help prevent falls. Hourly rounding includes checking on every patient at least once an hour and addressing common needs that usually include pain, personal needs, positioning and potty. Since most falls occur near the bed, the following interventions are key. Provide low beds, keep bed brakes locked, make sure the patient can reach all necessary items from bed, keep the bedside free of clutter and do not use all four of the bed rails. As we age every system of our body is affected. These changes can affect our balance and thus increase our risk of falling. - The nervous system responds slower to losses of balance with age. - The musculoskeletal system loses strength and range of motion as we age, which can also affect our balance. - The vestibular system can also lose function with age secondary to peripheral neuropathy and decreased vision. This can affect balance. There are many internal factors that increase fall risk as well: - The cardiovascular system can have a major impact on falls - hypotension (low blood pressure), heart rhythm problems, dizziness, faintness, and lightheadedness are all common causes of falls. - The neuromuscular system is of course another major player in falls - leg or muscle weakness, impaired mobility or loss of movement, poor circulation, unsteady gait, Parkinson's disease, and history of stroke are all huge fall risk indicators. - The musculoskeletal system plays a part too when there is joint pain and/or arthritis which can affect movement and mobility and increase fall risk. - Poor vision and poor hearing thanks to a decrease in the sensory system can lead to increased fall risk as well. - Lastly, the cognitive system plays a tremendous role in fall risk. Confusion, disorientation, intoxication, delirium, Alzheimer's disease and other dementia, as well as chronic mental illness may have the biggest impact on one's fall risk. External factors also play a huge role: - Medications are a major cause, especially psychoactive drugs. These drugs include sedatives, tranquilizers, anti-anxiety drugs and antidepressants. There are plenty of other drugs that may increase fall risk as well, especially if they are new to the patient. These include diuretics, beta-blockers, and any drug that can potentially cause dizziness, unsteadiness, or lowered blood pressure. Patients are also at an increased risk of falling if they take more than four prescription medications. - Environmental factors also play a role. Uneven surfaces, wet or slippery floors, inadequate lighting, clutter, incorrect bed height, poorly fitted or maintained wheelchairs, and a recent environmental change can increase fall risk. If you or a loved one are at an increased risk of falling, make sure the necessary prevention tools are in place. Whether at home or in the hospital, many steps can be put in place to help prevent falling and fall-related injuries. Try to identify the potential causes and look for their solutions or prevention interventions. With the right tools in place, we can all help prevent falls!
