Addressing the Gaps in Elderly Falling Prevention from the Perspective of a Human-Centered Design

Falls are the leading cause of morbidity and disability among older adults; the paper cites 36 million falls and 32,000 fatalities reported annually (CDC). Even one fall can have prolonged physical and psychological effects. As the "baby boom" generation enters retirement age, falls are expected to become more common. The paper notes that many studies have characterized fall risk factors, but there is still a gap in the study of interventions that address these factors. It therefore aims to review fall risk factors together with related interventions, identify gaps and suggest directions from a human-centered design perspective.

A systematic literature review following the PRISMA model (Preferred Reporting Items for Systematic Reviews and Meta-Analyses).

• Source: Web of Science, searched with combinations of fall-related terms ("falls", "falling", "fall"), older-adult terms (e.g., "elderly", "older adults", "seniors", "aging") and factor or intervention terms (e.g., "factors", "causes", "prevention", "interventions"), excluding reviews and meta-analyses.
• Exclusion criteria: studies on other age groups, protocols for future studies, and conference, systematic review or meta-analysis papers.
• Selection: of 366 studies found, 65 were included.
• Analysis: risk factors were grouped into intrinsic and extrinsic factors and further subgroups, and the intervention studies were grouped into categories.

• Review finding: Fall risk factors fall into intrinsic and extrinsic groups, with thirteen intrinsic and four extrinsic subgroups. Falls are a complex phenomenon caused by combinations of factors that can trigger one another (e.g., chronic conditions affecting gait, depression and fear of falling reducing activity, and polypharmacy, meaning the use of multiple medications).
• Review finding: Among extrinsic factors, the home environment matters, with bedrooms and bathrooms being the most dangerous areas. Socioeconomic characteristics (e.g., being poorly educated, single or unemployed) were also linked to more falls.
• Review finding: Of 31 intervention studies, 14 were multifactorial programs. Every study in the multifactorial and exercise groups (80% of the intervention literature reviewed) included exercise methods.
• Human-centered design gaps and directions (proposed): to improve adherence and engagement, integrate training into daily routines (e.g., future age-friendly smart home systems); provide feedback, performance evaluation and a sense of achievement, for example through smart exercise programs that connect older adults with coaches or physicians in real time, since face-to-face visits for every senior may become difficult; and make programs adaptable to individual needs and capabilities.

The review explored risk factors for falls and related intervention programs, and introduced ideas for improving exercise programs from a human-centered design perspective. The authors suggest that future studies could develop human-centered exercise programs, including a thorough user study to better understand the gaps and find suitable solutions. The paper does not state explicit limitations.
