Definition and management of very high fracture risk in women with postmenopausal osteoporosis: a position statement from the Brazilian Society of Endocrinology and Metabolism (SBEM) and the Brazilian Association of Bone Assessment and Metabolism (ABRASSO)

Several drugs are available for the treatment of osteoporosis in postmenopausal women. Over the last decades, most patients requiring pharmacological intervention were offered antiresorptive drugs as first-line therapy, while anabolic agents were considered a last resource for those with therapeutic failure. However, recent randomized trials in patients with severe osteoporosis have shown that anabolic agents reduce fractures to a greater extent than antiresorptive medications. Additionally, evidence indicates that increases in bone mineral density (BMD) are maximized when patients are treated with anabolic agents first, followed by antiresorptive therapy. This evidence is key, considering that greater increases in BMD during osteoporosis treatment are associated with a more pronounced reduction in fracture risk. Thus, international guidelines have recently proposed an individualized approach to osteoporosis treatment based on fracture risk stratification, in which the stratification risk has been refined to include a category of patients at very high risk of fracture who should be managed with anabolic agents as first-line therapy. In this document, the Brazilian Society of Endocrinology and Metabolism and the Brazilian Association of Bone Assessment and Metabolism propose the definition of very high risk of osteoporotic fracture in postmenopausal women, for whom anabolic agents should be considered as first-line therapy. This document also reviews the factors associated with increased fracture risk, trials comparing anabolic versus antiresorptive agents, efficacy of anabolic agents in patients who are treatment naïve versus those previously treated with antiresorptive agents, and safety of anabolic agents.

Differences in balance control between healthy younger and older adults during steady-state walking

Each year approximately one third of older adults fall and experience extensive musculoskeletal injuries and functional disabilities. An important element in maintaining dynamic balance is the regulation of whole-body angular momentum, which is achieved by proper foot placement with respect to the body center-of-mass as well as generation of appropriate ground reaction forces. Analyzing these quantities in younger and older adults may provide insight into differences in their underlying mechanics for maintaining dynamic balance. This study examined three-dimensional whole-body angular momentum in 13 healthy older (71.8 ± 8.3 years) and 9 younger (23.2 ± 2.8 years) adults walking at their self-selected and fastest-comfortable speeds. The older adults had a significantly higher range of frontal-plane angular momentum compared to the younger adults at both speeds, suggesting poorer mediolateral balance control. This difference was related to the older adults having a wider foot placement with respect to the body center-of-mass, which when combined with the vertical ground reaction force, created a higher destabilizing external moment during single-limb stance that acts to rotate the body towards the contralateral swing leg. To counteract this destabilizing moment, the older adults generated a higher hip abduction moment. There were no differences in the range of sagittal- and transverse-plane angular momentum between age groups at either speed. These results suggest that control of dynamic balance in the frontal-plane is more challenging than in the sagittal-plane for older adults and highlight the importance of proper weight transfer mechanisms and hip abductor force production for maintaining mediolateral balance during walking.

A scoping review of fall hazards in the homes of older adults and development of a framework for assessment and intervention

INTRODUCTION

Comprehensive evaluation and intervention provided by occupational therapists is effective in reducing the presence of fall hazards in the homes of older adults. The purpose of this study was to document known environmental hazards and to update a previous content analysis. A secondary goal reviewed a framework for evaluation and practice.

METHODS

A comprehensive scoping review of published academic articles was performed from 1996 to 2019 to answer: What environmental hazards have been associated with falls in the homes of community-dwelling older adults? Data was extracted in a standardised critical appraisal worksheet and content analysis was conducted. A review of a conceptual framework for assessment and intervention was conducted by international experts (n = 6) in face-to-face interviews.

RESULTS

Fourteen studies met the inclusion criteria for the scoping study. The studies reported 17 in-home environmental hazards: throw rugs/carpets, clutter, cords/wires, poorly placed light switches, items placed too low, items placed too high, no grab bars, toilet seats too low, uneven floor surfaces, slippery/wet surfaces, snowy/icy surfaces, backless/unsupportive shoes, unsteady stairs, inadequate lighting, inadequate heating/cooling, step stools without railings, and pets.

CONCLUSION

A comprehensive list of specific fall hazards in and around the homes of older adults and a guiding framework offers occupational therapists an evidence-based foundation for fall prevention efforts.

Identifying characteristics and outcomes that are associated with fall-related fatalities: multi-year retrospective summary of fall deaths in older adults from 2005-2012

BACKGROUND

Fall-related deaths continue to be the leading cause of accidental deaths in the older adult (65+ year) population. However, many fall-related fatalities are unspecified and little is known about the fall characteristics and personal demographics at the time of the fall. Therefore, this report describes the characteristics, circumstances and injuries of falls that resulted in older adult deaths in one U.S. County and explores the variables associated with fatal injuries from falls.

METHODS

This is a continued retrospective analysis of 841older adults whose underlying cause of death was due to a fall over an 8-year period (2005-2012). Demographics and logistic regression of fall characteristics and injuries were analyzed.

RESULTS

Falls that led to death most often occurred when walking in one's own home. Most of the residents in this study were community-dwellers who had previous comorbidities taking an average of six medications prior to their fall. Survival after a fall was on average 31 days. The two most common injuries after a fatal fall were hip fractures (54%), and head injuries (21%). A logistic regression identified two variables associated with hip fracture, advancing age (OR = 1.05, 95% confidence interval [CI] = 1.02-1.08) and diagnosis of a prior neurological condition (OR = 2.1, 95% CI = 1.4-3.1). Variables associated with head injuries included younger age (OR = .91, 95% CI = .89-.94), male gender (OR = 2.5, 95% CI = 1.7-3.8), prescribed anticoagulants (OR = 2.4, 95% CI = 1.5-3.9) and negative musculoskeletal comorbidity (OR = 1.9. 95% CI = 1.1-3.0).

CONCLUSION

Hip fractures and head injuries were the most common injury after a fall that led to death in older adults greater than 65 years. There are opposing risk factors for older adults who incur a hip fracture compared to a head injury. Thus, health professionals will need to individualize prevention efforts to reduce fall fatalities.

Fragility Fractures & Their Impact on Older People

Osteoporotic fractures, in particular hip and vertebral, are a major health burden worldwide. The majority of these fractures occur in the elderly population, resulting in one of the most important causes of mortality and disability in older ages. Their cost for societies is enormous and is forecast to steadily increase over the coming decades globally. Low bone mineral density (BMD) remains a key preventable risk factor for fractures. Screening and treatment of individuals with high risk of fracture is cost-effective. Predictive tools including clinical risk factors, minimisation of falls risk and public authorities' support to create Fracture Liaison Services are paramount strategies.

A fall prevention guideline for older adults living in long-term care facilities

BACKGROUND

Falls are among the most frequent critical health problems for older adults over 65 years of age and often result in consequential injuries.

AIM

This study developed a guideline covering risk factors and interventions for falls in order to prevent them from occurring in long-term care facilities.

METHODS

This study was grounded in the methodological approach of the Scottish Intercollegiate Guideline Network for establishing evidence-based guidelines: (1) establishment of the target population and scope of the guideline, (2) systematic literature review and critical analysis, (3) determination of the recommendation grade, (4) development of a draft nursing intervention guideline and algorithm, (5) expert evaluation of the draft nursing intervention guideline, and (6) confirmation of the final intervention guideline and completion of the algorithm.

RESULTS

The resulting evidence-based fall prevention guideline consists of a three-step factor assessment and a three-step intervention approach.

LIMITATIONS

The resulting guideline was based on the literature and clinical experts. Further research is required to test the guideline's feasibility in across long term care facilities.

CONCLUSION

This guideline can be used by nurses to screen patients who are at a high risk of falling to provide patient interventions to help prevent falls.

IMPLICATIONS FOR NURSING AND HEALTH POLICY

Considering the high rate of falls at long-term care facilities and the absence of evidence-based guidelines to prevent them, additional studies on falls at long-term care facilities are necessary. Meanwhile, given prior research that indicates the importance of human resources in the application of such guidelines, continuous investigations are needed as to whether the research outcomes are actually conveyed to nurses.

Causes of death determined in medicolegal investigations in residents of nursing homes: a systematic review

OBJECTIVES

To systematically review published research characterizing the nature and circumstances surrounding the death of older people in nursing homes specifically using information generated for medicolegal death investigations.

DESIGN

Systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement using the key words death, nursing homes, and medicolegal death investigation.

SETTING

Cross-sectional data from original, peer-reviewed articles published in English between 2000 and 2013 describing deaths of nursing home residents.

MEASUREMENTS

Information was extracted for analysis about study and population characteristics, number and type of deaths, study design, findings, and limitations.

RESULTS

Thirteen studies were identified. The studies examined external causes of deaths from suicide, choking, restraint or bed-related injuries, falls, and pressure injuries. Deaths were more frequent in women with existing comorbidities. Suicide was predominant in men. Identified risk factors and opportunities to reduce harm were identified at individual, organizational, and structural levels. Overall, the quality of the studies limited the aggregation and comparability of findings.

CONCLUSION

This systematic review informs researchers, clinicians and policy-makers about how to reduce external causes of death in nursing homes.

Fall-induced deaths among older adults: nationwide statistics in Finland between 1971 and 2009 and prediction for the future

BACKGROUND

Fall-related injuries and deaths of elderly people are a major public health concern.

METHODS

Using the Official Cause-of-Death Statistics of Finland we determined the current trends in the number and age-adjusted incidence (per 100,000 persons) of fall-induced deaths among older Finnish men and women by taking into account all persons 50 years of age or older who died because of a fall-induced injury between 1971 and 2009.

RESULTS

Among elderly Finnish men, the number of deaths due to falls increased considerably between the years 1971 and 2009, from 162 to 627 (a 287% increase). The age-adjusted incidence also increased from 43.4 (per 100,000 persons) in 1971 to 57.9 in 2000, but stabilized thereafter (57.3 in 2009). Among elderly Finnish women, the number of fall-induced deaths increased till the beginning of the new millennium (from 279 in 1971 to 499 in 2000) but stabilized thereafter (506 in 2009), and, in sharp contrast to men, women's age-adjusted incidence of fall-induced deaths declined during the entire study period, the incidence being 77.2 in 1971 while only 35.3 in 2009.

CONCLUSIONS

Between 1971 and 2009 the number of fall-induced deaths increased among elderly Finns. The changes were sex-specific so that men surpassed women in both the number and age-adjusted incidence of these fatal falls. Welcome observations were that men's age-adjusted incidence of fall-induced deaths started to stabilize during the new millennium and that in women this incidence continuously declined between 1971 and 2009.

Fatal falls in an ethnically diverse urban community: the link between demographic factors and the circumstances surrounding fatal falls

OBJECTIVES

Fatal falls cause more than 15,000 deaths per year in the United States. Despite this, the circumstances surrounding fatal falls in elderly adults are poorly understood. It is unknown whether these circumstances differ across ethnicities, although Hispanic American individuals are at reduced risk for fatal falls. This study sought to describe fatal falls in an urban, predominantly Hispanic, and white non-Hispanic community and to determine the association of demographics with the circumstances surrounding these falls (proximate factors).

METHODS

The death certificates and medical examiners' reports for all 328 elderly individuals experiencing a fatal fall in Miami-Dade County, FL, from 2005 to 2007 were reviewed for demographic and proximate factors such as the preceding activity and fall location.

RESULTS

Fatal falls in elderly adults were experienced mostly by individuals living in the community (80%) and affected all demographic subgroups, although 80% occurred in individuals older than 74 years. Most fatal falls occurred at home (74%), indoors (75%), and during nonvigorous activities such as walking (58%) and these tended to affect the oldest elderly. In addition, a significant number of fatal falls occurred in public locations, outdoors, and during vigorous activity, with these falls tending to affect younger individuals living without family. Hispanic ethnicity was not associated with proximate factors.

CONCLUSIONS

Fatal fall prevention is needed for elderly individuals living in the community and should target the oldest elderly adults living at home while helping to ensure that individuals who are living without family have the appropriate support. These data suggest that Hispanic individuals may benefit from prevention strategies developed in other populations.
