Falls related to Inappropriate Medications and Polypharmacy

The Importance of Polypharmacy on Falls in Elderly Patients

As a geriatric nurse practitioner, I frequently encounter the challenges posed by polypharmacy in elderly patients on a daily basis. Polypharmacy, defined as the concurrent use of multiple medications, is prevalent among older adults and is a significant risk factor for falls, which can lead to devastating outcomes.

Understanding Polypharmacy

Polypharmacy typically refers to the use of five or more medications simultaneously. In my patient population, it is very common to see patients on 15+ medication everyday.

Approximately 40% of older adults take five or more medications, with some studies indicating that this figure can rise to 90% in those residing in long-term care facilities.

The Link Between Falls and Polypharmacy

Falls are a leading cause of injury among older adults, and polypharmacy significantly contributes to this risk. Here are the key factors:

Medication Side Effects: Many medications can cause dizziness, sedation, or orthostatic hypotension (a drop in blood pressure from sit to standing), all of which increase the risk of falls. For example:

- Benzodiazepines, commonly prescribed for anxiety and sleep disorders, increase fall risk by 50%.

- Antidepressants can cause dizziness or balance issues, affecting up to 30% of users.

Drug Interactions: The more medications an elderly patient is prescribed, the higher the likelihood of harmful drug interactions. These interactions can exacerbate side effects that impair balance and coordination.

Fall Statistics and Outcomes

Fall Incidence: Approximately one in four older adults experiences a fall each year.

Injuries: Falls can lead to severe injuries, including fractures (especially hip fractures), head injuries, and even death. Nearly 20% of falls result in serious injury, such as a fracture or head trauma.

Mortality Rate: Falls are the leading cause of injury-related death among older adults, with over 30,000 deaths annually in the U.S. attributed to fall-related injuries.

Healthcare Costs: The financial burden of falls in older adults is significant, costing the U.S. healthcare system approximately $50 billion annually, including hospitalizations and rehabilitation.

Polypharmacy NEEDS to be addressed to Prevent Falls.

Comprehensive Medication Review: Regularly reviewing medications with a healthcare provider to assess necessity and potential interactions can help reduce the number of prescriptions.

Deprescribing: Encouraging the gradual discontinuation of non-essential medications can significantly lower the fall risk. Also dose reductions trials should be implemented.

Patient Education: Educating patients and caregivers about the risks associated with medications and the importance of reporting any side effects can lead to timely interventions.

As we care for the elderly population, it is crucial to recognize the relationship between polypharmacy and falls. By actively managing medications and addressing the risks associated with them, we can enhance the safety and quality of life for our older patients. Falls are not an inevitable part of aging; with appropriate interventions, we can help prevent them and improve outcomes for our elderly patients.
