Mortality trends for accidental falls in older people in Spain, 2000-2015

Effects of age, period, and birth cohort on fall-related mortality in older adults in Brazil from 1980 to 2019

Falls in older adults are a major public health problem. This study aimed to estimate the effects of age, period, and birth cohort on fall-related mortality in older adults in Brazil and its geographic regions, by sex, from 1980 to 2019. We conducted an ecological time-series study using data on fall-related deaths in older adults extracted from Brazilian Mortality Information System. Poisson models were adjusted for sex and geographic region to estimate age-period-cohort effects. From 1980 to 2019, Brazil recorded 170,607 fall-related deaths in older adults, with 50.1% occurring in women. More than half of these deaths occurred in the age group of 80 years or older (55%) and in the Southeast Region (52%). We observed an increase in fall-related mortality rates across all age groups and regions, regardless of sex. There was an increased risk of death in all periods after the reference period (2000 to 2004) in all geographic regions and for both sexes. We also observed a gradual increase in mortality risk for men born before 1914 and after 1935 compared to the reference cohort (1930 to 1934). In contrast, we found a protective effect across all birth cohorts for women. There was a consistent increase in fall-related mortality risk among older people in Brazil, posing a public health challenge. The findings highlight the urgent need for implementing public health policies that promotes older adults' health and prevents fall risks to improve this population's quality of life.

Fall-related mortality in Spain: trends and disparities by age and gender

BACKGROUND

Falls are a significant public health concern, particularly among older adults. This study aimed to analyse trends in fall-related mortality in Spain from 1999 to 2022, focusing on age and gender disparities.

METHODS

Using a longitudinal ecological study, we analysed trends in fall mortality. Using data from the Spanish National Institute of Statistics, age-standardised mortality rates (ASMRs) were calculated for different age groups and genders. Joinpoint regression analysis was employed to identify significant trends and calculate annual percentage changes in mortality rates.

RESULTS

Fall deaths in Spain surged from 1999 to 2022, with a significant increase in mortality rates. This increase was more pronounced among men than women, and the older adults aged 65 and older accounted for most fall-related deaths. Overall, ASMRs increased with age and were consistently higher for men across all age groups. Men experienced a 1.9% annual increase in ASMRs, with a significant rise starting in 2009. Women's ASMRs increased by 1.8% per year, with a more pronounced increase from 2007 to 2013 before slowing. Among those aged 65 and over, rates increased significantly across most age groups, with the ASMR for men rising by 2.7% per year and for women by 2%.

CONCLUSIONS

Fall mortality in Spain has significantly increased, particularly among older adults and men. The findings underscore the need for targeted fall prevention strategies, especially for high-risk groups. Future interventions should address gender-specific risks and emerging issues in middle-aged adults to effectively reduce fall-related mortality across all age groups.

Trends of falls mortality among older adults in urban and rural China, 1987-2021

BACKGROUND

Falls in older age pose a major public health concern, with unclear urban-rural patterns of falls mortality in China. This study examines the trends of late-life falls mortality in urban and rural China over a 35-year period.

METHODS

Falls mortality data were sourced from China's National Health Commission. Joinpoint regression analysis was used to examine changes in trends and age-period-cohort modelling to estimate age, period and cohort effects on fall-related mortality from 1987 to 2021. Net drift, local drift, longitudinal age curves and period relative risks were also calculated.

RESULTS

The age-standardised falls mortality in older age showed a long-term trend of initial decline prior to 2003, followed by a steep increase thereafter, with notable distinctions between urban and rural patterns. The rise in rural populations, particularly among older males, was more conspicuous. In rural areas, the decline in falls mortality diminished with age, contrary to the urban trend. Falls mortality increased with age in both urban and rural older populations, peaking in the group aged 85-89. The period effect curves of falls mortality in urban and rural areas both approximated a U-shaped pattern while there were minor variations in early cohorts.

CONCLUSIONS

China has experienced a consistent rise in late-life falls mortality in recent years. Notably, there are significant urban-rural disparities in age, period and cohort effects of fall-related mortality among older adults. Rural residents, males and older age groups have potential higher fatal-falls risk. Targeted strategies should be implemented to prevent late-life falls.

Prediction of the future number of fall-related emergency medical services calls in older individuals

BACKGROUND

Falls among older individuals contribute significantly to the rise in ambulance transport use. To recognize the importance of future countermeasures, we estimated the projected number and percentage of fall-related emergency medical service (EMS) calls.

METHODS

We examined the sex, age group, and location of falls among patients aged ≥ 65 years who contacted emergency services in Sapporo City from 2013 to 2021. Annual fall-related calls per population subgroup were calculated, and trends were analyzed. Four models were used to estimate the future number of fall-related calls from the 2025-2060 projected population: (1) based on the 2022 data, estimates from the 2013-2022 data using (2) Poisson progression, (3) neural network, (4) estimates from the 2013-2019 data using neural network. The number of all EMS calls was also determined using the same method to obtain the ratio of all EMS calls.

RESULTS

During 2013-2022, 70,262 fall-related calls were made for those aged ≥ 65 years. The rate was higher indoors among females and outdoor among males in most age groups and generally increased with age. After adjusting for age, the rate increased by year. Future estimates of the number of fall calls are approximately double the number in 2022 in 2040 and three times in 2060, with falls accounting for approximately 11% and 13% of all EMS calls in 2040 and 2060, respectively.

CONCLUSION

The number of fall-related EMS calls among older people is expected to increase in the future, and the percentage of EMS calls will also increase; therefore, countermeasures are urgently needed.

Differences in Falls and Physical Activity in Older Women From Two Generations

BACKGROUND

Falls and physical inactivity increase with age. However, physical activity, falls and their associations in older people born at different times are unclear.

METHODS

Women born 1921-26 and 1946-51 who completed follow-up questionnaires in 1999 (n = 8 403, mean (SD) age: 75 (1) years) and 2019 (n = 7 555; 71 (1) years) in the Australian Longitudinal Study on Women's Health. Self-reported noninjurious and injurious falls in the previous 12 months and weekly amounts and types of physical activity (brisk walking, moderate- and vigorous-intensity) were compared between the cohorts using Chi-square tests. Associations between physical activity, and noninjurious and injurious falls were estimated using multinomial logistic regressions informed by a directed acyclic graph.

RESULTS

A greater proportion of the later (1946-51) cohort (59%) reached 150-300 minutes of weekly physical activity, as recommended by the World Health Organization, compared to the earlier (1921-26) cohort (43%, p < .001). A greater proportion of the later cohort reported noninjurious falls (14% vs 8%). Both cohorts reported similar proportions of injurious falls (1946-51:15%, 1921-26:14%). In both cohorts, participation in 150-300 minutes of physical activity was associated with lower odds of noninjurious falls (adjusted Odds Ratio, 95% CI: 1921-26: 0.66, 0.52-0.84; 1946-51: 0.78, 0.63-0.97) and injurious falls (1921-26: 0.72, 0.60-0.87; 1946-51: 0.78, 0.64-0.96).

CONCLUSIONS

Participation in recommended levels of physical activity was associated with reduced falls in both cohorts. However, generational differences were found with more falls and more physical activities in the women born later. Future studies could examine the reasons contributing to the generational differences.

Impact of dietary sodium restriction on falls among middle-aged and older adults: Results of an 8-year longitudinal study

AIM

This study aimed to understand the relationship between dietary sodium restriction (DSR) and falling experiences in middle-aged and older adults.

METHODS

The 8-year follow-up data from the Taiwan Longitudinal Study on Aging, covering 5131 individuals aged ≥50 years, were analyzed using random-effects panel logit models. Participants were asked to indicate whether they were told by a physician to reduce or avoid sodium intake from food and whether they had had fall experiences during the past year. We modelled falling experiences as a function of DSR (independent variable), involuntary body weight loss and walking difficulty (mediators), and chronic diseases (moderator), adjusting for individual-level characteristics.

RESULTS

Individuals with DSR were at a higher risk of falls compared with those with no DSR (adjusted odds ratio [AOR] = 1.30, 95% confidence interval [CI] = 1.11-1.53). This effect was more prevalent in individuals with a history of stroke (AOR = 1.85, 95% CI = 1.19-2.87). Those told to reduce sodium intake by a physician were likely to lose weight involuntarily (AOR = 1.20, 95% CI = 1.05-1.36) and had difficulty walking up two or three flights of stairs alone (AOR = 2.38, 95% CI = 1.73-3.27), which mediated the effect of DSR on increased fall risk (AOR = 1.15, 95% CI = 0.95-1.38). We found a temporal effect: participant reactions to short- and mid-term DSR were significant.

CONCLUSIONS

DSR was associated with a greater likelihood of falls among middle-aged and older adults, particularly those with a history of stroke. Geriatr Gerontol Int 2024; 24: 292-299.

Ability to Process Multisensory Information Is Impaired in Open Angle Glaucoma

PRCIS

Patients with glaucoma demonstrated deficiencies in their ability to process multisensory information when compared with controls, with those deficiencies being related to glaucoma severity. Impaired multisensory integration (MSI) may affect the quality of life in individuals with glaucoma and may contribute to the increased prevalence of falls and driving safety concerns. Therapeutic possibilities to influence cognition in glaucoma should be explored.

PURPOSE

Glaucoma is a neurodegenerative disease of the optic nerve that has also been linked to cognitive health decline. This study explored MSI as a function of glaucoma status and severity.

METHODS

MSI was assessed in 37 participants with open angle glaucoma relative to 18 age-matched healthy controls. The sound-induced flash illusion was used to assess MSI efficiency. Participants were presented with various combinations of simultaneous visual and/or auditory stimuli and were required to indicate the number of visual stimuli observed for each of the 96 total presentations. Central retinal sensitivity was assessed as an indicator of glaucoma severity (MAIA; CenterVue).

RESULTS

Participants with glaucoma performed with equivalent capacity to healthy controls on unisensory trials ( F1,53 =2.222, P =0.142). Both groups performed equivalently on congruent multisensory trials involving equal numbers of auditory and visual stimuli F1,53 =1.032, P =0.314). For incongruent presentations, that is, 2 beeps and 1 flash stimulus, individuals with glaucoma demonstrated a greater influence of the incongruent beeps when judging the number of flashes, indicating less efficient MSI relative to age-matched controls ( F1,53 =11.45, P <0.002). In addition, MSI performance was positively correlated with retinal sensitivity ( F3,49 =4.042, P <0.025), adjusted R ²=0.15).

CONCLUSIONS

Individuals with open angle glaucoma exhibited MSI deficiencies that relate to disease severity. The type of deficiencies observed were similar to those observed among older individuals with cognitive impairment and balance issues. Impaired MSI may, therefore, be relevant to the increased prevalence of falls observed among individuals with glaucoma, a concept that merits further investigation.

[Prognosis in elderly patients with falls treated in emergency departments: The EDEN-3 study]

OBJECTIVE

To investigate whether falls in people ≥65 years old are a prognostic factor for adverse events compared to the rest of older patients who consult emergency departments, and identify factors related to a worse long-term evolution.

METHOD

EDEN cohort that included patients ≥65 years old. Those patients who consulted for fall and the rest were distinguished. Twelve variables were collected. For comparison: two groups matched by fall propensity score. We compared mortality at one year and combined adverse event post-discharge at one year. In patients with falls, variables independently related to evolution were identified.

RESULTS

Two thousand seven hundred and forty-five patients treated for falls and 22,920 for other reasons. Mortality at one year was 14.4% (9.5% vs. 15.0%, respectively, P<.001) and the combined post-discharge adverse event at one year was 60.6% (52.2% vs. 61.7%, respectively, P<.001). In 4748 patients matched by fall propensity score (2372 in each group), the inverse association between consultation for fall and mortality (HR: 0.705, 95% CI: 0.5880.846) and post-discharge combined adverse event (0.758, 0.701-0.820) remained significant. Factors associated with mortality in patients with falls were ≥80 years (2.097, 1.521-2.891) and comorbidity (2.393, 1.574-3.636) while being female was a protective factor (0.758, 0.584-0.985). Between the factors associated with post-discharge combined adverse hospitalization in the index event was a protective factor (0.804, 0.685-0.943).

CONCLUSIONS

Patients over 65 years of age treated in the emergency room for falls have a better prognosis. Hospitalization was a protective factor of combined postdischarge adverse event.

Temporal, seasonal, and spatial patterns in fall-related mortality in Japan: Analysis of national vital statistics from 1975 to 2019

BACKGROUND

Falls are a significant public health issue in aging societies. This study aimed to examine the temporal, seasonal, and spatial patterns in fall-related mortality in Japan, and to investigate the potential factors associated with fall-related mortality.

METHODS

The number of unintentional fall-related deaths from 1979 to 2019 were obtained from Japanese vital statistics and crude and direct age-standardized mortality rates (DSR) were calculated. We also calculated the standardized mortality ratio (SMR) to determine seasonal and prefectural differences. In addition, spatial regression was conducted to examine the potential factors associated with fall-related mortality.

RESULTS

The DSR among those over 65 years old showed a decreasing trend from 1979, but remained unchanged from 1990 to 2019. Based on the spatial regression model, the factors significantly associated with SMRs were the proportion of the aged population (Coefficient: 0.049), the number of hospitals (0.118), the number of clinics (1.169), the number of hospital beds (-0.060), and the number of physiotherapists (-0.069) for men; and the proportion of aged single households (-0.060), the number of hospitals (0.132), the number of clinics (1.498), the number of hospital beds (-0.051), and the number of physicians (-0.308) for women.

CONCLUSIONS

Fall-related mortality among Japanese elderly people has remained unchanged in recent years. In addition, seasonal and spatial patterns were also observed, and it was found that demographic data and healthcare resources in the prefectures affected fall-related mortality rates. Appropriate prevention measures of fall-related deaths should be considered according to the region-specific characteristics and issues.

Outcomes of care at higher-level trauma centers in octogenarians with a history of anticoagulant use who fall from ground level

BACKGROUND

The appropriate care of octogenarian trauma patients after a fall from ground level (FFGL) is a key factor for better outcomes. The purpose of this study is to use data from a national database to evaluate the outcomes of patients who are 80-89 years old with a history of anticoagulant use, sustained a FFGL, and were treated at a higher-level care institution.

METHODS

The Trauma Quality Improvement Program (TQIP) database of the calendar year 2017-2018 was accessed for the study. All hospitalized trauma patients between the ages of 80-89 years old with a history of anticoagulant use and sustaining an injury after FFGL were included in the study. Other variables included in the study are sex [male], race [white], initial systolic blood pressure (SBP mmHg), Injury Severity Score (ISS), Glasgow Coma Scale (GCS), hypotension with an SBP<110 mmHg and other comorbidities. The outcomes of the patients were compared with the care at higher-level trauma centers (Level I & Level II) and lower-level trauma centers (Level III) using propensity matched analysis.

RESULTS

After propensity matching, 2348 patients were identified in each group. There was no clinically significant difference between the patients' characteristics who were treated at higher-level and lower-level care centers. A paired matched analysis showed greater mortality in patients who were treated at higher-level care centers compared to lower-level care centers (3.7% vs 2.6%, P = 0.03). The absolute difference in mortality was 1.1%[95% CI: 0.001, 0.022] which may not have any clinical relevance. A greater number of patients were discharged to home and a lesser number of patients were discharged to a skilled nursing facility (SNF) when they were treated at higher-level trauma centers.

CONCLUSION & RELEVANCE

The care at higher-level trauma centers did not show any benefit in-hospital mortality in the short term. A higher number of patients was discharged to home without assistance.

Chronic Vitamin E Deficiency Dysregulates Purine, Phospholipid, and Amino Acid Metabolism in Aging Zebrafish Skeletal Muscle

Muscle wasting occurs with aging and may be a result of oxidative stress damage and potentially inadequate protection by lipophilic antioxidants, such as vitamin E. Previous studies have shown muscular abnormalities and behavioral defects in vitamin E-deficient adult zebrafish. To test the hypothesis that there is an interaction between muscle degeneration caused by aging and oxidative damage caused by vitamin E deficiency, we evaluated long-term vitamin E deficiency in the skeletal muscle of aging zebrafish using metabolomics. Zebrafish (55 days old) were fed E+ and E- diets for 12 or 18 months. Then, skeletal muscle samples were analyzed using UPLC-MS/MS. Data were analyzed to highlight metabolite and pathway changes seen with either aging or vitamin E status or both. We found that aging altered purines, various amino acids, and DHA-containing phospholipids. Vitamin E deficiency at 18 months was associated with changes in amino acid metabolism, specifically tryptophan pathways, systemic changes in the regulation of purine metabolism, and DHA-containing phospholipids. In sum, while both aging and induced vitamin E deficiency did have some overlap in altered and potentially dysregulated metabolic pathways, each factor also presented unique alterations, which require further study with more confirmatory approaches.

Impact of Falls Within 3 Months on the Short-Term Prognoses of Elderly Patients in Intensive Care Units: A Retrospective Cohort Study Using Stabilized Inverse Probability Treatment Weighting

BACKGROUND

Falls are a major public health problem in the older adults that can lead to poor clinical outcomes. There have been few reports on the short-term prognoses of older critically ill patients, and so we sought to determine the impact of falls on elderly patients in intensive care units (ICUs).

PATIENTS AND METHODS

This retrospective study of 4503 patients (aged 65 years or older) analyzed data in the Medical Information Mart for Intensive Care-III critical care database. Of those, 2459 (54.6%) older adults are males, and 2044 (45.4%) older adults are females. Based on information from the medical care record assessment forms, patients were classified into the following two groups based on whether they had a fall within the previous 3 months: falls (n=1142) and nonfalls (n=3361). The primary outcomes of this study were 30- and 90-day mortality. Associations between the results of the Kaplan-Meier (KM) survival analysis, Cox proportional-hazards regression models, and subgroup analysis and its outcomes were analyzed using stabilized inverse probability treatment weighting (IPTW).

RESULTS

KM survival curves with stabilized IPTW indicated that 30- and 90-day survival rates were significantly lower in elderly critically ill patients with a history of falls within the previous 3 months than in those patients without a history of falls (all p<0.001). Multivariate Cox proportional-hazards regression analysis indicated that 30- and 90-day mortality rates were 1.35 times higher (95% confidence interval [CI]=1.16-1.57, p<0.001) and 1.36 times higher (95% CI=1.19-1.55, p<0.001), respectively, in elderly critically ill patients with a history of falls within the previous 3 months than in those patients without a history of falls.

CONCLUSION

Experience of falls within the previous 3 months prior to ICU admission increased the risk of short-term mortality and affected the prognoses of elderly patients. Falls should therefore receive adequate attention from clinical healthcare providers and management decision-makers.

One-Legged Balance Performance and Fall Risk in Mid and Later Life: Longitudinal Evidence From a British Birth Cohort

INTRODUCTION

The one-legged balance test is widely used as a fall risk screening tool in both clinical and research settings. Despite rising fall prevalence in midlife, there is little evidence examining balance and fall risk in those aged <65 years. This study investigated the longitudinal associations between one-legged balance and the number of falls between ages 53 and 68 years.

METHODS

The study included 2,046 individuals from the Medical Research Council National Survey of Health & Development, a British birth cohort study. One-legged balance times (eyes open, maximum: 30 seconds) were assessed at ages 53 years (1999) and 60-64 years (2006-2010). Fall history within the last year (none, 1, ≥2) was self-reported at ages 60-64 years and 68 years (2014). Multinomial logistic regressions assessed the associations between balance and change in balance with subsequent falls. Models adjusted for anthropometric, socioeconomic, behavioral, health status, and cognitive indicators. Analysis occurred between 2019 and 2022.

RESULTS

Balance performance was not associated with single falls. Better balance performance at age 53 years was associated with decreased risk of recurrent falls at ages 60-64 years and 68 years, with similar associations between balance at age 60-64 years and recurrent falls at age 68 years. Those with consistently lower balance times (<15 seconds) were at greater risk (RRR=3.33, 95% CI=1.91, 5.80) of recurrent falls at age 68 years in adjusted models than those who could balance for 30 seconds at ages 53 years and 60-64 years.

CONCLUSIONS

Lower balance and consistently low or declining performance were associated with a greater subsequent risk of recurrent falls. Earlier identification and intervention of those with poor balance ability can help to minimize the risk of recurrent falls in aging adults.

Combined effect of lower muscle quality and quantity on incident falls and fall-related fractures in community-dwelling older adults: A 3-year follow-up study

OBJECTIVE

Falls and fractures are serious geriatric adverse events worldwide, and skeletal muscle is considered to be a key factor in these incidents. The objective of this study was to investigate the combined effect of lower muscle quality and quantity on the incidence of falls and fall-related fractures in a 3-year follow-up period among community-dwelling older adults.

METHODS

We recruited community-dwelling adults aged 65 years and older who were living independently in 2018. A total of 773 older participants were analyzed in this study. The outcomes were incident falls and fall-related fractures during the 3-year follow-up period. At baseline, we assessed muscle quality and quantity using ultrasonography, and we categorized the participants into four groups based on their combination of poor/better muscle quality and poor/better muscle quantity. Cox proportional hazards models were used to estimate the hazard ratios (HRs) and 95 % confidence intervals (CIs) of the relationships among items in the four groups and the time to incident falls and fall-related fractures.

RESULTS

During the 3-year follow-up period, 178 participants (23.0 %) had a fall incident and 51 participants (6.6 %) had fall-related fractures. Older adults with lower muscle quality and quantity had significantly elevated risks of incident falls according to multivariate analyses using older adults with better muscle quality and quantity as the reference (adjusted HR: 1.54 [95 % CI 1.06-2.23]). However, there were no significant differences in fall-related fractures among the four groups.

CONCLUSION

We found that lower muscle quality and quantity led to higher incidents of falls; thus, identifying community-dwelling older adults with lower muscle quality and quantity is necessary to provide them fall preventive measures and maybe to reduce fall-related outcomes.

Enhancing referral processes within an integrated fall prevention pathway for older people: a mixed-methods study

OBJECTIVES

Multifactorial interventions, which involve assessing an individual's risk of falling and providing treatment or onward referral, require coordination across settings. Using a mixed-methods design, we aimed to develop a process map to examine onward referral pathways following falls risk assessment in primary care.

SETTING

Primary care fall risk assessment clinics in the South of Ireland.

PARTICIPANTS

Focus groups using participatory mapping techniques with primary care staff (public health nurses (PHNs), physiotherapists (PT),and occupational therapists (OT)) were conducted to plot the processes and onward referral pathways at each clinic (n=5).

METHODS

Focus groups were analysed in NVivo V.12 using inductive thematic analysis. Routine administrative data from January to March 2018 included details of client referrals, assessments and demographics sourced from referral and assessment forms. Data were analysed in Stata V.12 to estimate the number, origin and focus of onward referrals and whether older adults received follow-up interventions. Quantitative and qualitative data were analysed separately and integrated to produce a map of the service.

RESULTS

Nine staff participated in three focus groups and one interview (PHN n=2; OT n=4; PT n=3). 85 assessments were completed at five clinics (female n=69, 81.2%, average age 77). The average number of risk factors was 5.4 out of a maximum of 10. Following assessment, clients received an average of three onward referrals. Only one-third of referrals (n=135/201, 33%) had data available on intervention receipt. Primary care staff identified variations in how formally onward referrals were managed and barriers, including a lack of client information, inappropriate referral and a lack of data management support.

CONCLUSION

Challenges to onward referral manifest early in an integrated care pathway, such as clients with multiple risk factors sent for initial assessment and the lack of an integrated IT system to share information across settings.

The mortality trends of falls among the elderly adults in the mainland of China, 2013-2020: A population-based study through the National Disease Surveillance Points system

BACKGROUND

Fall in elderly is a major public health problem. Characterizing trends in fall mortality in different subpopulations could help identifying the needs and developing preventive program for target groups. Here we evaluated the trends of fall-related deaths in Chinese mainland among adults aged ≥60 years specific in sex, age, and provinces, to measure the change in this mortality rate between 2013 and 2020, and to explore the underlying factors influencing this change.

METHODS

Mortality data were retrieved from the National Disease Surveillance Points system(DSPs) of China, a national-level and provincial-level representative data source, to estimate the impact of elderly falls on mortality in the mainland of China and the specific provinces from 2013 to 2020. The joinpoint regression model was used to estimate the temporal trend of mortality in elderly fallen by calculating the annual percentage change (APC).

FINDINGS

The age-standardized falls mortality was 10·438 per 100 000 in 2020. The age-standardized mortality of elderly falls in total and female showed a steady increasing trend (APC=1·96%, p = 0·023 total; APC=3·42%, p = 0·003 female), with it was stable in males (APC=1.26%, p>0·05). Fall mortality among the elderly was more common in people over 70 years of age and increased sharply. The death rates and APCs were highest among the oldest age groups(aged≥85 years). The higher fall mortality was mainly focused in the southeast and central regions, and lower rates were in the northeast provinces and Tibet.

INTERPRETATION

Since 2013, the overall fall-related mortality trend among individuals aged ≥60 years has been consistently increasing in China, making it most critical public health challenge. Adherence interventions and increased social support for those at most risk should be considered.

FUNDING

None.

Mortality from falls in the elderly in the Federal District, Brazil: characteristics and time trend, 1996-2017

OBJECTIVE

To describe and analyze the temporal trend of deaths from falls in the elderly in the Federal District, Brazil, between 1996 and 2017.

METHODS

This was a descriptive study based on data on deaths from falls held on the Mortality Information System, part of the database of the Information Technology Department of the Brazilian National Health System. Demographic, socioeconomic, type of fall and place of death variables were investigated. Segmented linear regression was performed to analyze annual percent change (APC), adopting p≤0.05.

RESULTS

Data from 2,828 deaths from falls in the elderly were analyzed (54.2% women; 45.8% men). There was an increase in mortality from falls in the elderly aged 80 years and over (APC 3.0; p<0.001).

CONCLUSION

There was an increasing trend of mortality from falls in the elderly aged 80 years and over. Strategies are needed to reduce deaths from falls, especially among older elderly people.

Tendência de mortalidade por quedas em idosos, no Brasil, no período de 2000–2019

RESUMO Objetivo: Analisar a tendência da mortalidade por quedas entre idosos, no Brasil, no período de 2000 a 2019. Métodos: Trata-se de um estudo epidemiológico, analítico, com delineamento ecológico de séries temporais. Realizou-se uma análise retrospectiva utilizando dados secundários em saúde, extraídos do Sistema de Informação sobre Mortalidade (SIM) no período específico. Foram calculadas taxas padronizadas de mortalidade geral e específicas por sexo e faixa etária. Para a observação da tendência de mortalidade, utilizou-se o modelo de Prais-Winsten e taxa de incremento anual (TIA). Resultados: No período de 2000 a 2019, foram identificados 135.209 óbitos decorrentes das quedas em idosos. A mortalidade por queda em geral, no período estudado, foi crescente (β=0,023; p<0,001; TIA=5,45%). Observou-se que tanto o sexo masculino (β=0,022; p<0,001; TIA=5,19%) quanto o feminino (β=0,024; p<0,001; TIA=5,72%) apresentaram tendência crescente. Com relação à faixa etária, os resultados apontaram também para tendência de mortalidade crescente em todos os estratos etários, porém maior em idosos com idade ≥80 anos (β=0,027; p<0,001; TIA=6,38%). Conclusão: Observou-se tendência crescente nas taxas de mortalidade no Brasil durante a série histórica estudada. Esses achados sugerem a importância da definição de uma linha de cuidado para esse segmento etário, tendo como foco a promoção da saúde na pessoa idosa e a prevenção dos riscos de quedas, visando a uma redução no número de óbitos por essa causa e favorecendo a qualidade de vida dos idosos.

Mortality trend from falls in Brazilian older adults from 2000 to 2019

ABSTRACT Objective: To analyze the trend of mortality from falls among older adults in Brazil from 2000 to 2019. Methods: This is an epidemiological, analytical study with an ecological time-series design. A retrospective analysis was performed using secondary health data extracted from the Brazilian Mortality Information System in the specific period. Standardized rates of general and sex- and age-specific mortality were calculated. To observe the mortality trend, the Prais-Winsten model and the Annual Increase Rate (AIR) were used. Results: We identified 135,209 deaths resulting from falls in older adults in the period from 2000 to 2019. Mortality from falls in general, during the study period, had an upward trend (β=0.023; p<0.001; AIR=5.45%). We observed that both men (β=0.022; p<0.001; AIR=5.19%) and women (β=0.024; p<0.001; AIR=5.72%) had an upward trend. Regarding age group, the results also pointed to an upward mortality trend in all age strata, although higher in older people aged ≥80 years (β=0.027; p<0.001; AIR=6.38%). Conclusion: There was an upward trend in mortality rates in Brazil during the time series studied. These findings suggest the importance of defining a line of care for this age group, focusing on promoting health in older adults and preventing the risk of falls, aiming at a reduction in the number of deaths from this cause and favoring the quality of life of this population.

Trend of fall-related mortality among the elderly

OBJECTIVE

To analyze the temporal trend of fall-related mortality in elderly in Brazil from 2008 to 2016.

METHOD

Study of time series of rates of fall-related mortality according to CID-10 from 2008 to 2016. Data from the Mortality Information System on death registers of people ≥ 60 living in Brazil were used. The specific rates of fall-related mortality among the elderly were calculated through the ratio between the number of deaths and the elderly population of that year and region. The populational information was obtained from the 2000 and 2010 censuses. The variation rate and temporal trend were obtained through linear regression (p < 0.05).

RESULTS

The fall-related deaths among the elderly aged ≥ 60 amounted to 72,234 (31.2%). Falls from the same level were the most frequent (53.8%) and death rates in all ages ranged from 29.7 to 44.7 per 100,000 elders. Fall-related deaths increased with age.

CONCLUSION

There was a growing trend of fall-related deaths among elderly in all age groups, an event which is avoidable through the adoption of preventive measures. The high rates and growing trend of fall-related deaths, as well as the aging of the Brazilian population, suggest that public policies for protecting the elderly must be prioritized.

The effects of different frequencies of rhythmic acoustic stimulation on gait stability in healthy elderly individuals: a pilot study

The efficacy of rhythmic acoustic stimulation (RAS) to improve gait and balance in healthy elderly individuals is controversial. Our aim was to investigate, through 3D gait analysis, the effect of different types of RAS (fixed frequency and based on subject-specific cadence), using conventional gait parameters and the trunk displacement as readouts. Walking at a fixed frequency of 80 bpm, the subjects showed extended duration of gait cycle and increased gait variability while the same individuals, walking at a fixed frequency of 120 bpm, showed reduced trunk sway and gait cycle duration. With regard to the RAS at subject-specific frequencies, walking at 90% of the subject-specific average cadence did not significantly modify the gait parameters, except for the speed, which was reduced. In contrast, walking at 100% and 110% of the mean cadence caused increased stride length and a slight reduction of temporal parameters and trunk sway. In conclusion, this pilot study shows that using RAS at fixed frequencies might be an inappropriate strategy, as it is not adjusted to individual gait characteristics. On the other hand, RAS frequencies equal to or slightly higher than each subject's natural cadence seem to be beneficial for gait and stability.

Bibliometric Analysis on Research Trend of Accidental Falls in Older Adults by Using Citespace-Focused on Web of Science Core Collection (2010-2020)

The present study aimed to identify the trends in research on accidental falls in older adults over the last decade. The MeSH (Medical Subject Headings) and entry terms were applied in the Web of Science Core Collection. Relevant studies in English within articles or reviews on falls in older adults were included from 2010 to 2020. Moreover, CiteSpace 5.6.R5 (64-bit) was adopted for analysis with scientific measurements and visualization. Cooper Cyrus, Stephen R Lord, Minoru Yamada, Catherine Sherrington, and others have critically impacted the study of falls in older adults. Osteoporosis, dementia, sarcopenia, hypertension, osteosarcopenia, traumatic brain injury, frailty, depression, and fear of falling would be significantly correlated with falls in older adults. Multiple types of exercise can provide effective improvements in executive cognitive performance, gait performance, quality of life, and can also lower the rates of falls and fall-related fractures. Fall detection, hospitalization, classification, symptom, gender, and cost are the current research focus and development direction in research on falls in older adults. The prevention of falls in older adults is one of the most important public health issues in today’s aging society. Although lots of effects and research advancements had been taken, fall prevention still is uncharted territory for too many older adults. Service improvements can exploit the mentioned findings to formulate policies, and design and implement exercise programs for fall prevention.

Risk-of-falling related outcomes improved in community-dwelling older adults after a 6-week sideways walking intervention: a feasibility and pilot study

BACKGROUND

Aging increases fall risk and alters gait mechanics and control. Our previous work has identified sideways walking as a potential training regimen to decrease fall risk by improving frontal plane control in older adults' gait. The purposes of this pilot study were to test the feasibility of sideways walking as an exercise intervention and to explore its preliminary effects on risk-of-falling related outcomes.

METHODS

We conducted a 6-week single-arm intervention pilot study. Participants were community-dwelling older adults ≥ 65 years old with walking ability. Key exclusion criteria were neuromusculoskeletal and cardiovascular disorders that affect gait. Because initial recruitment rate through University of Nebraska at Omaha and Omaha community was slower than expected (3 participants∙week- 1), we expanded the recruitment pool through the Mind & Brain Health Labs registry of the University of Nebraska Medical Center. Individualized sideways walking intervention carried out under close supervision in a 200 m indoor walking track (3 days∙week- 1). Recruitment and retention capability, safety, and fidelity of intervention delivery were recorded. We also collected (open-label) walking speed, gait variability, self-reported and performance-based functional measures to assess participants' risk-of-falling at baseline and post-intervention: immediate, and 6 weeks after the completion of the intervention.

RESULTS

Over a 7-month period, 42 individuals expressed interest, 21 assessed for eligibility (21/42), and 15 consented to participate (15/21). Most of the potential participants were reluctant to commit to a 6-week intervention. Desired recruitment rate was achieved after revising the recruitment strategy. One participant dropped out (1/15). Remaining participants demonstrated excellent adherence to the protocol. Participants improved on most outcomes and the effects remained at follow-up. No serious adverse events were recorded during the intervention.

CONCLUSIONS

Our 6-week sideways walking training was feasible to deliver and demonstrated strong potential as an exercise intervention to improve risk-of-falling outcomes in community-dwelling older adults. In a future trial, alternative clinical tools should be considered to minimize the presence of ceiling/floor effects. A future large trial is needed to confirm sideways walking as a fall prevention intervention.

Effects of a Multicomponent Program on Fall Incidence, Fear of Falling, and Quality of Life among Older Adult Nursing Home Residents

Background

Falling is one of the most common problems in older adults and can lead to additional health problems. This study aimed to determine the effects of a multicomponent program on fall incidence and quality of life in older adult nursing home residents.

Methods

This was a quasi-experimental study with a pretest and post-test design. The study population comprised 55 older adults residing in nursing homes. The intervention was a multicomponent program including physical activities, training sessions, and physical environment modifications in nursing homes that was conducted for 8 weeks. The data collection tools included a socio-demographic characteristics form and questionnaires pertaining to the quality of life and fear of falls, which were completed by the participants before and after the intervention.

Results

The mean age of the participants was 68.48 years, and most (90%) were illiterate. We observed a significant difference between the mean number of falls and the scores for fear of falling before and after the intervention (p<0.001). We also observed a significant difference between the total quality of life scores and all of the related dimensions before and after the intervention, indicating that the quality of life of the older adults had improved after the intervention (p<0.001).

Conclusion

The results of this study indicated that the multicomponent fall prevention program was effective in improving the quality of life, fall rate, and fear of falling among older residents in nursing homes. Further studies are needed to explore the long-term effects of these interventions.

Nutritional Status Is Associated with Function, Physical Performance and Falls in Older Adults Admitted to Geriatric Rehabilitation: A Retrospective Cohort Study

Nutritional status is relevant to functional recovery in patients after an acute process requiring rehabilitation. Nevertheless, little is known about the impact of malnutrition on geriatric rehabilitation. This study aimed to determine the association between nutritional status at admission and the evolution of functional and physical outcomes, as well as the capability of nutritional status to identify fallers among patients admitted to geriatric rehabilitation for different reasons. This was a retrospective cohort study of 375 patients. Data collected included age, gender, diagnosis at admission, comorbidities, cognitive and nutritional status, functional and physical measurements, length of stay, mortality and falls. Orthogeriatric patients with worse nutritional status according to the Mini Nutritional Assessment-Short Form (MNA-SF) had a significantly lower Barthel Index at admission and discharge with worse functional gain and poorer outcomes in the Short Physical Performance Battery (SPPB). However, in hospital-deconditioned patients, the MNA-SF score was not significantly associated with functional and physical recovery. Poor nutritional status at admission increased the risk of experiencing at least one fall during rehabilitation in orthogeriatric patients. However, hospital-deconditioned patients who fell had better SPPB scores than those who did not fall. Our results demonstrate the importance of nutritional status in the clinical evolution of orthogeriatric patients throughout the rehabilitation process.

Increase in fall-related hospitalization, mortality, and lethality among older adults in Brazil

OBJECTIVE To estimate the trends of fall-related hospitalization, mortality, and lethality among older adults in Brazil and regions. METHODS This is a descriptive study based on data from the Hospital Information System of the Brazilian Unified Health System. We included records of every older adult, aged 60 years or older, hospitalized for accidental fall from January, 1998 to November, 2015 in all Brazilian regions. We selected the codes E885, E886, E880, E884, E884 from the International Classification of Diseases, 9th revision, and W01, W03, W10, W17, W18 from the 10th revision, and calculated fall-related hospitalization and mortality rates per 100,000 inhabitants, as well as lethality. To estimate trends, we applied the Prais-Winsten regression for time series analysis. RESULTS During the period, 1,192,829 fall-related hospitalizations occurred, among which 54,673 had a fatal outcome; lethality was 4.5%. Hospitalization rates showed upward trends, with seasonality, in Brazil (11%), and in the Northeast (44%), Midwest (13%), and South regions (14%). The North showed a decreasing hospitalization rate (48%), and the Southeast a stationary one (3%). CONCLUSIONS In Brazil, fall-related hospitalizations, mortality, and lethality among older adults showed an upward trend from 1998 to 2015, with seasonal peaks in the second and third quarters. Considering we are in plain demographic transition, to improve hospital healthcare and encourage falls prevention programs among older adults is essential.

Fall-related injuries for three ages groups - Analysis of Swedish registry data 1999-2013

INTRODUCTION

The objective of this study was to analyze which factors (including factors pertaining to the individual, the household, and the local area) increase the risk of fall injuries for the three age groups with the highest risk for fall injuries in Sweden.

METHOD

The study combined longitudinal data covering the period 1999-2013 from several different official registries from Statistics Sweden as well as from the Swedish health care system and fitted the models to data using mixed model regressions.

RESULTS

Three age groups had a markedly heightened risk for fall injuries: 1-3-year olds, 12-14 year olds, and the elderly (65+). The home was the most common location for fall injuries, as about 40% of all fall injuries occur in the home. Only for the elderly strong predictors for fall injuries were found, and these were: age, single household, and special housing.

CONCLUSIONS

There is preventive potential in the special residences for the elderly and disabled. People living in these special residences make up a strongly selected group that needs extra safe environments. Our findings indicate that their needs are currently not meet. Practical applications: Design of special residences for the elderly and disabled should aim at reducing the consequences of falling.

Falls and long-term survival among older adults residing in care homes

Objectives

To assess the association between having suffered a fall in the month prior to interview and long-term overall survival in nursing-home residents.

Methods

Retrospective cohort study conducting an overall survival follow-up of 689 representative nursing-home residents from Madrid, Spain. Residents lived in three types of facilities: public, subsidized and private and its information was collected by interviewing the residents, caregivers and/or facility physicians. Residents contributed to follow-up time from their baseline interviews until death or being censored at the end of the 5-year follow-up period. The association between suffering a fall during the month prior to interview and long-term overall survival was analyzed using Cox proportional hazards models. To adjust for potential confounders we used progressive adjusted models. We then repeated the analyses with severity of the fall (no fall, non-severe, severe) as the main independent variable.

Results

After a 2408 person-year follow-up (median 4.5 years), 372 participants had died. In fully-adjusted models, residents who had suffered any kind of fall in the previous month showed virtually the same survival rates compared to non-fallers (hazard ratio (HR) = 1.03; 95% CI = 0.75–1.40). There was a weak graded relationship between increased fall severity and survival rates for the non-severe fall group (HR = 0.92; 95% CI = 0.58–1.45) and the severe fall group (HR = 1.36; 95% CI = 0.73–2.53) compared with residents who had not suffered any kind of fall. The hazard ratios for severe falls were higher in men, residents with less comorbidity, fewer medications, and those functionally independent.

Conclusion

We found no associations between having suffered a fall in the month prior to interview and long-term survival; neither did we find a marked association when severity of fall was accounted for in the whole population. In some subgroups, however, the results merit further scrutiny.

Examining outcomes in cases of elderly patients who fell from ground level at home with normal vital signs at the scene: An analysis of the National Trauma Data Bank

BACKGROUND

The purpose of the study was to evaluate whether the higher level of care significantly affected the outcomes of elderly patients who fell from ground level at home and had a normal physiological examination at the scene.

METHODS

Patients 65 years and older, with normal physiological measures at the scene (Glasgow Coma Scale score = 15, systolic blood pressure > 90 and <160 mm Hg, heart rate (HR) ≥ 60 and ≤100) from the 2012 to 2014 National Trauma Data Bank data sets were included in the study. Patients' characteristics, existing comorbidities, and outcomes were compared between Level I or Level II designated trauma centers (higher level care [group 1]) and Levels III, IV, and unranked/nontrauma centers (lower level care [group 2]). Following initial analyses, propensity score matching was performed, and the rate of in-hospital mortality, median time (days) to death or discharge, and discharge disposition were compared.

RESULTS

Of the 40,800 patients who met inclusion criteria, 18,813 patients were matched from each group on age, sex, race, systolic blood pressure, HR, respiratory rate, Injury Severity Score, and comorbidity statuses. There was no evidence of a significant difference regarding in-hospital mortality (2.5% vs. 2.3%), time to death (median [interquartile range]: 6 [3-11] vs. 6 [3-11]), or time to hospital discharge (median [interquartile range]: 5 [5-5] vs. 5 [5-5]). However, the rate of required postdischarge care (78.9% vs. 81.7%) varied significantly between the groups.

CONCLUSION

Higher levels of care failed to show any significant survival benefits or shorten the time to hospital discharge; however, a significantly higher proportion of patients from lesser-care facilities required follow-up services after discharge.

How large should a cause of death be in order to be included in mortality trend analysis? Deriving a cut-off point from retrospective trend analyses in 21 European countries

OBJECTIVES

The International Classification of Diseases (ICD-10) distinguishes a large number of causes of death (CODs) that could each be studied individually when monitoring time-trends. We aimed to develop recommendations for using the size of CODs as a criterion for their inclusion in long-term trend analysis.

DESIGN

Retrospective trend analysis.

SETTING

21 European countries of the WHO Mortality Database.

PARTICIPANTS

Deaths from CODs (3-position ICD-10 codes) with ≥5 average annual deaths in a 15-year period between 2000 and 2016.

PRIMARY AND SECONDARY OUTCOME MEASURES

Fitting polynomial regression models, we examined for each COD in each country whether or not changes over time were statistically significant (with α=0.05) and we assessed correlates of this outcome. Applying receiver operating characteristicROC curve diagnostics, we derived COD size thresholds for selecting CODs for trends analysis.

RESULTS

Across all countries, 64.0% of CODs had significant long-term trends. The odds of having a significant trend increased by 18% for every 10% increase of COD size. The independent effect of country was negligible. As compared to circulatory system diseases, the probability of a significant trend was lower for neoplasms and digestive system diseases, and higher for infectious diseases, mental diseases and signs-and-symptoms. We derived a general threshold of around 30 (range: 28-33) annual deaths for inclusion of a COD in trend analysis. The relevant threshold for neoplasms was around 65 (range: 61-70) and for infectious diseases was 20 (range: 19-20).

CONCLUSIONS

The likelihood that long-term trends are detected with statistical significance is strongly related to COD size and varies between ICD-10 chapters, but has no independent relation to country. We recommend a general size criterion of 30 annual deaths to select CODs for long-term mortality-trends analysis in European countries.

Early risk stratification of in hospital mortality following a ground level fall in geriatric patients with normal physiological parameters

BACKGROUND

The purpose of this study was to identify risk factors of mortality for geriatric patients who fell from ground level at home and had a normal physiological examination at the scene.

METHODS

Patients aged 65 and above, who sustained a ground level fall (GLF) with normal scene Glasgow Coma Scale (GCS) score 15, systolic blood pressure (SBP) > 90 and <160 mmHg, heart rate ≥ 60 and ≤100 beats per minute) from the 2012-2014 National Trauma Data Bank (NTDB) data sets were included in the study. Patients' characteristics, existing comorbidities [history of smoking, chronic kidney disease (CKD), cerebrovascular accident (CVA), diabetes mellitus (DM), and hypertension (HTN) requiring medication], injury severity scores (ISS), American College of Surgeons' (ACS) trauma center designation level, and outcomes were examined for each case. Risks factors of mortality were identified using bivariate analysis and logistic regression modeling.

RESULTS

A total of 40,800 patients satisfied the study inclusion criteria. The findings of the logistic regression model for mortality using the covariates age, sex, race, SBP, ISS, ACS trauma level, smoking status, CKD, CVA, DM, and HTN were associated with a higher risk of mortality (p < .05). The fitted model had an Area under the Curve (AUC) measure of 0.75.

CONCLUSION

Cases of geriatric patients who look normal after a fall from ground level at home can still be associated with higher risk of in-hospital death, particularly those who are older, male, have certain comorbidities. These higher-risk patients should be triaged to the hospital with proper evaluation and management.

Fall-related mortality trends in older Japanese adults aged ≥65 years: a nationwide observational study

OBJECTIVES

Fall-related mortality among older adults is a major public health issue, especially for ageing societies. This study aimed to investigate current trends in fall-related mortality in Japan using nationwide population-based data covering 1997-2016.

DESIGN

We analysed fall-related deaths among older persons aged ≥65 years using the data provided by the Japanese Ministry of Health, Labour and Welfare.

RESULTS

The crude and age-standardised mortality rates were calculated per 100 000 persons by stratifying by age (65-74, 75-84 and ≥85 years) and sex. To identify trend changes, a joinpoint regression model was applied by estimating change points and annual percentage change (APC). The total number of fall-related deaths in Japan increased from 5872 in 1997 to 8030 in 2016, of which 78.8% involved persons aged ≥65 years. The younger population (65-74 years) showed continuous and faster-decreasing trends for both men and women. Average APC among men aged ≥75 years did not decrease. Among middle-aged and older women (75-84 and ≥85 years) decreasing trends were observed. Furthermore, the age-adjusted mortality rate of men was approximately twice that of women, and it showed a faster decrease for women.

CONCLUSIONS

Although Japanese healthcare has shown improvement in preventing fall-related deaths over the last two decades, the crude mortality for those aged over 85 years remains high, indicating difficulty in reducing fall-related deaths in the super-aged population. Further investigations to uncover causal factors for falls in older populations are required.

Evaluating the outcomes of blunt thoracic trauma in elderly patients following a fall from a ground level: higher level care institution vs. lower level care institution

BACKGROUND

The purpose of the study is to evaluate the outcomes of higher level care institutions of elderly patients who sustained a thoracic injury after a ground-level fall (GLF).

HYPOTHESIS

Higher level care institutions have a better survival.

METHODS

The National Trauma Data Bank (NTDB) data set of 2012-2014 was accessed for the study. All patients, 65 years of age and older, who experienced a GLF and sustained a thoracic injury, were included in the study. Patient demography, injury characteristics including injury severity score (ISS), Glasgow coma scale (GCS) motor score, comorbidities, and patient outcomes were compared between the higher level care institution [American College of Surgeon (ACS) level I and level II trauma centers) and lower level care institution (ACS level III and level IV and unranked-trauma centers). On univariate analysis, some significant patient characteristic differences were found; therefore, propensity score matching and paired analyses were performed. All P values are two sided, and a P value < 0.05 was considered statistically significant.

RESULTS

Out of the 15,256 patients who satisfied the inclusion criteria, approximately 52% (7994) of patients were treated at a higher level care institution. On univariate analysis, significant differences were found between the lower level care institution and higher level care institution regarding male gender (44.2% vs.46%, P = 0.03), ISS median [interquartile] (9 [5-12] vs. 9 [5-13], P < 0.001), history of alcohol abuse (4.2% vs. 5.3%, P = 0.007), dementia (8.7% vs. 9.8%, P = 0.02), bleeding disorder or history of anticoagulation use (17% vs. 18.4%, P = 0.03), obesity (5% vs. 6.6%, P < 0.001), and abbreviated injury scale (AIS) thorax (2 [1-3] vs. 3 [2-3], P < 0.001). After propensity score matching, the majority of the characteristics were balanced with few exceptions, including ISS, AIS ≥ 3 head and abdomen, and P values < 0.05. The overall in-hospital mortality was not significantly different between the higher level care institution vs. the lower level care institution (4.4% vs. 3.9%, P = 0.14). The median hospital length of stay and 95% confidence interval between both groups was (5 [5, 5] and 5 [5, 5], P = 0.72).

CONCLUSION

Treating elderly patients with blunt chest trauma in higher level care institutions failed to show any benefit in overall survival or hospital length of stay.

Mortality From Falls Among US Adults Aged 75 Years or Older, 2000-2016

This study uses National Vital Statistics System data from 2000-2016 to characterize trends in mortality from falls in the US population aged 75 years or older.

Sarcopenia and its association with falls and fractures in older adults: A systematic review and meta-analysis

Sarcopenia is a potentially modifiable risk factor for falls and fractures in older adults, but the strength of the association between sarcopenia, falls, and fractures is unclear. This study aims to systematically assess the literature and perform a meta-analysis of the association between sarcopenia with falls and fractures among older adults. A literature search was performed using MEDLINE, EMBASE, Cochrane, and CINAHL from inception to May 2018. Inclusion criteria were the following: published in English, mean/median age ≥ 65 years, sarcopenia diagnosis (based on definitions used by the original studies' authors), falls and/or fractures outcomes, and any study population. Pooled analyses were conducted of the associations of sarcopenia with falls and fractures, expressed in odds ratios (OR) and 95% confidence intervals (CIs). Subgroup analyses were performed by study design, population, sex, sarcopenia definition, continent, and study quality. Heterogeneity was assessed using the I² statistics. The search identified 2771 studies. Thirty-six studies (52 838 individuals, 48.8% females, and mean age of the study populations ranging from 65.0 to 86.7 years) were included in the systematic review. Four studies reported on both falls and fractures. Ten out of 22 studies reported a significantly higher risk of falls in sarcopenic compared with non-sarcopenic individuals; 11 out of 19 studies showed a significant positive association with fractures. Thirty-three studies (45 926 individuals) were included in the meta-analysis. Sarcopenic individuals had a significant higher risk of falls (cross-sectional studies: OR 1.60; 95% CI 1.37-1.86, P < 0.001, I²  = 34%; prospective studies: OR 1.89; 95% CI 1.33-2.68, P < 0.001, I²  = 37%) and fractures (cross-sectional studies: OR 1.84; 95% CI 1.30-2.62, P = 0.001, I²  = 91%; prospective studies: OR 1.71; 95% CI 1.44-2.03, P = 0.011, I²  = 0%) compared with non-sarcopenic individuals. This was independent of study design, population, sex, sarcopenia definition, continent, and study quality. The positive association between sarcopenia with falls and fractures in older adults strengthens the need to invest in sarcopenia prevention and interventions to evaluate its effect on falls and fractures.

Severe head injury in elderly: 6-year comparison of treatment and outcome between southern Finland and Navarra (Spain)

PURPOSE

To compare the profile, treatment and outcome of elderly patients with severe traumatic brain injuries (TBI) between southern Finland and Navarra (Spain).

METHODS

Data collected from, 2010 to 2015, in the Major Trauma Registry of Navarra (MTR-N) and the Helsinki Trauma Registry (HTR) were compared. Patients with New Injury Severity Score (NISS) ≥ 16 and age ≥ 65 with isolated severe TBI were considered. Patients who had been admitted to the hospital ≥ 24 h after the trauma, had been pronounced dead before hospital arrival, or had been injured by hanging, drowning or burns, were excluded. Outcome was defined by 30-day hospital mortality. The expected mortality was calculated using the Revised Injury Severity Classification score II (RISC II). Other compared data included demographics, injury mechanism, pre-hospital and hospital treatment, and time intervals.

RESULTS

A total of 305 (MTR-N) and 137 (HTR) patients were included in the outcome analysis. The standardized mortality ratio with 95% confidence interval was for MTR-N 1.4 (1.1-1.6) and for HTR 0.8 (0.6-1.1). Patients in Navarra were older (average 79.7 vs. 75.0) while in southern Finland the percentage of pre-hospital intubation in patients with GCS ≤ 8 (75.0% vs 50.0%) and ICU admission (72.2% vs 22.0%) were higher.

CONCLUSION

The better adjusted outcome of elderly patients with severe TBI in southern Finland in comparison to Navarra could be due to higher rate of pre-hospital intubation and/or higher rate of ICU admissions in southern Finland. Increasing number of elderly patients with severe TBI necessitate uniformly accepted protocols in pre- and in-hospital management.

Epidemiology of traumatic brain injury in the elderly over a 25 year period

OBJECTIVE

To identify the changes in the epidemiology of traumatic brain injury (TBI) in a cohort of patients older than 65 years old admitted in the Intensive care unit of a third-level hospital over a 25 year period.

MATERIAL AND METHODS

A retrospective cohort study conducted on patients over 65 years-old admitted with the diagnosis of TBI into an intensive care unit of a Spanish university hospital. The demographic, clinical variables were collected at the time of admission, including comorbidities, injury mechanisms, and injuries presented, and days of stay in ICU. A statistical analysis was carried out by five-year periods.

RESULTS

A total of 446 TBI in patients over 65 years were included. In the analysis, an increase was observed in the proportion of patients presenting with epidural haematoma (1.39% in the period 1990-1995 vs. 9.46% in 2010-2015), with a significant linear tendency (P=.018). Falls from own height have increased from 8.33% (1991-1995) to currently more than 70% (2011-2015), P<.001. The percentage of traffic accidents declined from 26.39% to 3.95% in the last period, P<.001.

CONCLUSIONS

In the last 25 years there seems to be evidence of a change in the origins of TBI in the elderly in our field.
