Fall Prevention in the Elderly: Nursing Interventions Guide

Introduction

Falls occur when people lose their center of gravity or balance — either attempting balance restoration but failing, or not attempting it at all. Falls may be caused by any uncontrollable external force or by internal body conditions such as strokes, seizures, or loss of consciousness (King, 2003). Fall rates are, at times, undervalued among elderly patients, even without any obvious cognitive weakening, because reconstructing the dynamics of a fall is typically difficult. Syncope-related falls are very often linked to retrograde amnesia (Cummings, Nevitt, & Kidd, 1988); further, between forty and sixty percent of falls occur with no witnesses present.

An estimated 34 percent of individuals aged 65 and older, half of non-hospitalized or non-institutionalized octogenarians, 43 percent of nursing home residents, and 26 percent of hospitalized patients suffer at least one fall per year (Rubenstein & Josephson, 2002). Fall likelihood and rates increase with age; American females aged 70 and older show a greater likelihood of falling compared with their male counterparts, and experience twice the injury rate (Gangadhar et al., 2011). Fall cases among hospitalized patients and nursing home residents in the 65-and-older age category are roughly three times higher than falls among community-dwellers (approximately 1.5 per bed per year), likely because of their intrinsic fragility, even within more closely monitored settings.

American Geriatrics Society (AGS) guidelines suggest altering environmental risk factors, implementing balance improvement exercises and training programs, properly using support instruments such as walkers and canes, and providing hip protection as components of complex intervention. Preliminary evaluation together with inclusive neuro-autonomic and cardiovascular analysis largely facilitates final diagnosis and plays a major role in identifying fall etiology and guiding treatment (Ungar et al., 2013).

Fall pathogenesis is normally complex, arising from environmental factors as well as age-related physiological and pathological elements. Identifying risk factors is essential for planning preventive measures (Mayor, 2004). Between ten and twenty-five percent of falls result from muscle weakness and ambulatory issues (Campbell, Borrie, & Spears, 1989). According to a wide-ranging longitudinal study, one in ten individuals aged 65 and older require support to cross a room, two in ten require support to climb stairs, and four in ten cannot walk more than five hundred meters (Rubenstein, 2006). Elderly individuals commonly experience muscle weakness; certain studies reveal lower limb weakness among eighty percent of nursing home residents and forty-eight percent of non-institutionalized individuals (Robbins et al., 1989). Case-control research indicates that patients who have experienced a fall have greater difficulty walking compared to those who have not (Tinetti et al., 1986). While muscle strength declines naturally with aging, this is largely attributed to physical inactivity and co-morbidity. Researchers have more recently noted that distal muscle weakening causes significant postural instability, while proximal weakness diminishes compensatory arm motion (Horlings et al., 2009).

A majority of falls among institutionalized individuals occur while they are engaging in activities that carry intrinsic risk due to associated vasovagal reflexes and postural changes — such as getting into or out of a bathtub, or rising from bed. Obstacles within urban areas, including unprotected crossings and uneven sidewalks, also contribute. One meta-analytic study on the relationship between medication use and falls found that taking more than four medications — particularly digoxin, antiarrhythmic agents, benzodiazepines, diuretics, antipsychotics, and antidepressants — significantly increased fall risk. Benzodiazepines contribute substantially to falls in both chronic and acute use (Hartikainen et al., 2007).

During assessment, accounting for the synergism and interaction among various fall-related factors is especially vital given the multifactorial etiology of falls. Scholars have demonstrated that as the number of risk factors increases, the likelihood of falling rises proportionally. The proportion of community-dwellers experiencing repeated falls increases from 10 to 69 percent as risk factors grow from one to four or more (Nevitt, Cummings, & Black, 1989).

Practice Issue and Organizational Context

Previous studies point to numerous reasons why multifactorial interventions currently known to nursing home personnel often fail in practice. Implementing these interventions requires healthcare teams to have access to precise information on resident risk factors — including health status, behavior, and medications administered — to develop customized risk reduction strategies. Continuous coordination between interdisciplinary and direct care personnel is also necessary for carrying out the elements of a risk reduction plan. Findings from a past comprehensive nursing home workforce behavioral study (Anderson et al., 2003) indicated that personnel typically lacked the necessary connections for acquiring and sharing relevant information about their residents (Colón-Emeric et al., 2006; Corazzini et al., 2005; Piven et al., 2006).

The most widely adopted local interaction strategies that overburdened personnel relied upon — to avoid punishment or additional workload — included aloofness, withholding information, working in isolation without offering or seeking assistance, and operating with a "not my responsibility" attitude. Such approaches produced fragile working relationships, limited use of diverse frameworks for understanding fall-related risk factors, and inadequate information flow. Training personnel to achieve reductions in multifactorial risk factors will likely be ineffective if these foundational communication issues are not first addressed (Colón-Emeric et al., 2013).

American nursing homes serve both short-term residents — largely admitted for post-acute healthcare under Medicare Part A benefits — and long-term residents receiving custodial care. Unlike long-term residents who, by virtue of their extended stay, are familiar with the setting and known to staff, newly admitted residents face an unfamiliar environment and are not well recognized by institutional personnel. This complicates fall risk factor determination and management. Moreover, many newly admitted post-acute residents present with greater fall likelihood due to weakened functional status. Research outcomes may be distorted if short-stay and long-stay patients are combined in the same sample. While substantial literature explores the relationship between nursing home institutional characteristics, long-stay resident outcomes, and care quality, relatively little information exists on these linkages in new admissions (Leland, Gozalo, Teno, & Mor, 2013).

The aims of this project include: highlighting Fall Management initiative significance and implementation for helping nursing facilities deliver patient-focused, personalized healthcare; proposing improvements in workforce communication, shared decision-making, care quality, and adoption of collaborative local interaction approaches among intervention community nursing homes; appraising preventive measures to decrease nursing home falls; and describing the nursing role in reducing falls among inpatients.

The PICO question guiding this study is: Among the geriatric and adult population, how effective are discrete nursing interventions compared with a complex fall prevention initiative for reducing inpatient falls?

Inadequate healthcare funding, an increasingly aging population, and growing chronic illness incidence underscore the importance of preventing care dependency and disabling health conditions among elderly people. Various measures are available to prevent falls and associated injuries, spanning from diagnostic processes that identify vulnerable population groups to multifaceted interventions designed to reduce recognized risk factors. However, the fiscal and medical efficacy of most proposed fall prevention approaches remains unclear (Balzer, Bremer, Schramm, Luhmann, & Raspe, 2012).

Evidence Review and Synthesis

A cost-effectiveness analysis of an interdisciplinary, multifactorial fall prevention program was conducted using effectiveness and cost data from a randomized controlled trial by Markle-Reid and colleagues (2010). One hundred and nine respondents were randomly allocated to usual care or the intervention program; the overall analytical sample included 92 respondents who completed six-month follow-up. Researchers examined two subgroups: the young-old (aged 75–84) and the old-old (aged 85 and older). Multifactorial fall prevention was found to be cost-effective depending on the participants' age and decision-makers' willingness to pay per fall prevented. This study contributed to the literature on age-related impacts on the cost-effectiveness of multifactorial programs, finding the intervention to be cost-effective in specific contexts. Understanding how age affects program cost-effectiveness can help target resources toward individuals most likely to benefit (Isaranuwatchai, Perdrizet, Markle-Reid, & Hoch, 2017).

According to a Cochrane Systematic Review published in 2012, clinical evaluation by a clinician, combined with personalized risk factor treatment, follow-up, and referral where required, helped achieve a 24% reduction in fall rates (Gillespie et al., 2010). The United States Preventive Services Task Force similarly found that multifactorial clinical evaluation, management, and follow-up decreased falls. Falls and related injuries commonly arise from interactions among numerous risk factors, several of which are potentially modifiable. Primary care providers contribute significantly to reducing fall risk determinants in elderly patients. Guidelines recommend yearly screenings for high-risk patient identification, along with detailed risk evaluation and management of modifiable risk factors in this population. Routine exercise to improve balance and strength, alongside vitamin D supplementation, may reduce falls and serve as suitable prevention strategies for both high- and low-risk populations. Facilitating elderly patients' understanding and participation in fall prevention activities proves crucial to the effectiveness of clinician efforts (Phelan, Mahoney, Voit, & Stevens, 2016).

The heterogeneity of existing research, combined with a lack of blinding and other intrinsic methodological limitations, complicates the evaluation of intervention efficacy. As a result, meta-analyses are often unsuitable, and individual study outcomes are difficult to interpret. These issues also undermine the informative value of economic analyses. Given these limitations, current elderly fall prevention recommendations are not fully evidence-supported. In particular, novel recommendations must account for the dependency of potential outcomes on the specific characteristics of the care context or target population, including factors that affect a target population's readiness to adopt preventive measures (Balzer, Bremer, Schramm, Luhmann, & Raspe, 2012).

Research librarians drew on references from MEDLINE's National Library of Medicine database, the National Institutes of Health through Entrez, and the Cochrane Library in November 2012; an additional search was conducted in March 2015 to identify English-language sources on elderly fall injury prevention. The search strategy was defined to assess only articles addressing falls that resulted in injury. Articles were restricted to randomized controlled trials, clinical trials on human subjects, reviews, practice guidelines, and meta-analyses. A total of 1,830 works were identified at the outset.
