Medication use and fall risk among older adults in long-term care facilities: A cross-sectional analysis.

Abstract

Background: Falls among older adults are a major concern, frequently resulting in injuries and a decreased quality of life. While medication use is known to be a key contributor to fall risk, the specific medications have not been thoroughly investigated. This study is vital to investigate the relationship between specific medications and fall risk, aiming to strengthen safety measures and minimise falls among the elderly in care facilities.

Objectives: To determine the relationship between medication use and the risk of falling among the elderly living in Long Term Care (LTC) facilities.

Methods: The study used a cross-sectional design to investigate males and females, aged 60 years and older, living in retirement facilities in the City of Cape Town. A convenient sampling method was utilised to recruit a total of 258 participants from multiple long-term care facilities in Cape Town, South Africa. The Spearman's rank correlation coefficient was used to determine associations between falls, fall risk factors, and various medications used.

Results: Majority of participants were at low risk (81%; n=211), 15.1% (n=39) at moderate risk and 3.1% (n=8) at high risk for falling. Antidepressant [χ² (1)=4.941; p=0.026; OR=2.083 (95% CI: 1.082, 4.012)] and anti-diabetic [χ² (1)=4.097, p=0.043, OR=2.070 (95% CI: 1.013, 4.228)] medications were the only drugs significantly associated with falling.

Conclusion: These findings highlight the significant association between antidepressant and anti-diabetic medications and an increased risk of falls. Effective medication management and fall prevention strategies are essential among this vulnerable population. Clinicians should carefully assess the risks of these medications when prescribing to older adults and consider alternative treatments when necessary.
