BackgroundFalls are a leading cause of injury and hospital readmissions in older adults. Understanding the distribution of acute treatment costs across inpatient and emergency department settings is critical for informed investment and evaluation of fall prevention efforts.MethodsThis study used the 2016-2018 National Inpatient Sample and National Emergency Department Sample. Annual treatment cost of fall injury among adults 65 years and older was estimated from charges, applying cost-to-charge and professional fee ratios. Weighted multivariable generalized linear models were used to separately estimate cost for inpatient and emergency department (ED) setting by injury type and individual demographic and health characteristics after adjusting for payer and hospital level characteristics.ResultsOlder adults incurred an estimated 922,428 inpatient and 2.3 million ED visits annually due to falls with combined annual costs of $19.8 billion. Over half of inpatient visits for fall injury were for fracture. Notably, 23% of inpatient visits were for fractures other than hip fracture and 14% of inpatient visits were for multiple fractures with costs totaling $3.4 billion and $2.5 billion, respectively. Annual ED costs were driven by superficial injury totaling $1.5 billion. Cost of ED visits were higher for adults 85 years and older (adjusted cost ratio (aCR): 1.11, 95% Confidence Interval (CI)I: 1.11-1.12) and those with dementia (aCR: 1.14, 95% CI: 1.13-1.15). Higher inpatient and ED visit cost was also associated with high-energy falls and discharge to post-acute care.ConclusionThe study found that more than 3 million older adults in the United States seek hospital care for fall injuries annually, a major concern given increasing capacity strain on hospitals and EDs. The $20 billion in annual acute treatment costs attributed to fall injury indicate an urgent need to implement evidence-based fall prevention interventions and underscores the importance of newly launched ED-based fall prevention efforts and investments in geriatric emergency departments.Copyright © 2023 Elsevier Ltd.
