Real World Evidence of Wearable Smartbelt for Mitigation of Fall Impact in Older Adult Care.

Structured Abstract Falls with major injuries are a devastating occurrence for an older adult with outcomes inclusive of debility, loss of independence and increased mortality. The incidence of falls with major injuries has increased with the growth of the older adult population, and has further risen as a result of reduced physical mobility in recent years due to the Coronavirus pandemic. The standard of care in the effort to reduce major injuries from falling is provided by the CDC through an evidence-based fall risk screening, assessment and intervention initiative (STEADI: Stopping Elderly Accidents and Death Initiative) and is embedded into primary care models throughout residential and institutional settings nationwide. Though the dissemination of this practice has been successfully implemented, recent studies have shown that major injuries from falls have not been reduced. Emerging technology adapted from other industries offers adjunctive intervention in the older adult population at risk of falls and major fall injuries. Technology in the form of a wearable smartbelt that offers automatic airbag deployment to reduce impact forces to the hip region in serious hip-impacting fall scenarios was assessed in a long-term care facility. Device performance was examined in a real-world case series of residents who were identified as being at high-risk of major fall injuries within a long-term care setting. In a timeframe of almost 2 years, 35 residents wore the smartbelt, and 6 falls with airbag deployment occurred with a concomitant reduction in the overall falls with major injury rate.

Potential Solutions for the Mitigation of Hip Injuries Caused by Falls in Older Adults: A Narrative Review.

BACKGROUND: Hip injuries caused by falling are common and often catastrophic for older adults. There is thus an urgent need to develop solutions designed to mitigate fall injuries to the hip by reducing the forces created on the body by ground impact. METHODS: The goal of this narrative review was to synthesize published literature on available products developed with the expressed goal of reducing fall-related hip injuries. RESULTS: Three categories were identified: passive wearables (eg, hip protectors), active wearables (eg, instrumented belts with deployable airbags), and compliant flooring. Laboratory studies indicate that each technology can reduce peak forces induced by simulated falls. Considerable preliminary data suggest that passive wearables and compliant flooring may reduce fall-related injuries within long-term care facilities. Controlled trials of specific types of these 2 technologies, however, have produced inconsistent results. While little is known about the effectiveness of active wearables, promising early data indicate the feasibility of an instrumented belt worn around the waist to effectively deploy an airbag to protect the hips prior to ground impact. Important challenges associated with one or more identified technologies included poor adherence to instructed wear as well as the potential for significant physical or time burden to caregivers or health care professionals. CONCLUSIONS: Passive wearables, active wearables, and compliant flooring have shown promise in reducing fall-related hip injuries in older adults. Still, each type of product is accompanied by limited real-world data and/or significant challenges that must be overcome to maximize effectiveness and minimize unintended side effects.
