Trends in fall-related emergency department visits involving alcohol among older adults: 2011–2020

Abstract Falls disproportionately affect older adults (≥65) resulting in three million emergency department (ED) visits annually. The relationship between alcohol and falls is unclear, but side effects of alcohol consumption include gait and balance impairments, which are risk factors for falls. This study examined trends of older adult fall-related ED visits involving alcohol from 2011-2020. Alcohol data are not routinely collected during ED visits. Alcohol involvement was identified from National Electronic Injury Surveillance System-All Injury Program free-text narratives using natural language processing and text analytic techniques. Joinpoint regression was used and cross-validated with SAS to determine significant older adult fall changes from 2011-2020 by sex and to compare older adult trends to adults < 65 (20-34, 35-54, 55-64). From 2011-2020, 2.2% of all ED visits for older adult falls involved alcohol. Alcohol-involved fall ED visit rates for older adults increased annually by 7.2% (95%CI:6.1%-8.4%). These older adult ED visit rates increased by 6.8% (95%CI:5.4%-8.2%) for males and 7.4% (95%CI:6.0%-8.9%) for females annually. For adults aged 20-34 and 35-54, alcohol-involved fall ED visit rates increased annually by 1.3% (95%CI:0.1%-2.6%) and 3.8% (95%CI:2.7%-5.0%), respectively, until 2017 and then decreased by 4.4% (95%CI:1.2%-7.5%) and 4.0% (95%CI:0.3%-7.5%). For adults aged 55-64, ED visit rates increased annually by 8.5% (95%CI:6.8%-10.2%) until 2018 and then stabilized. Documenting alcohol use when treating falls is important for monitoring trends. Assessing alcohol use in conjunction with assessments for other fall risk factors can inform healthcare providers on effective strategies to recommend to reduce fall risk.
