Vestibular schwannoma can cause vestibular dysfunction; however, conflicting evidence exists regarding whether this affects the incidence of fall-related injuries in this patient population. This matched cross-sectional and cohort study assess the risk of fall-related injuries in patients with vestibular schwannoma. The study included patients with vestibular schwannoma treated at a tertiary referral hospital in Sweden between 1988 and 2014. Information on fall-related injuries was obtained from the National Patient Register, and matched population comparisons were randomly selected in a 1:25 ratio. Fall-related injuries occurring pre- (within 5 years before the diagnosis of vestibular schwannoma) and post-diagnostically (up to 3 years after diagnosis or intervention) were registered. The association between vestibular schwannoma and fall-related injuries was estimated using logistic regression and Cox proportional hazards analyses. We identified 1153 patients with vestibular schwannoma (569 [49%] women and 584 [51%] men), and 28815 population comparisons. Among the patients, 9% and 7% had pre- and post-diagnostic fall-related injuries, respectively, and among the comparisons, 8% and 6% had pre- and post-diagnostic fall-related injuries, respectively. There was no increased risk of pre- (OR 1.14; CI 0.92–1.41) or post-diagnostic 1 year (HR 1.16; CI 0.87–1.54) or 3 years (HR 1.11; CI 0.89–1.29) fall-related injury among the total patient cohort. In age-stratified analyses, we found an increased risk of pre-diagnostic fall-related injury among patients aged 50–69 years (OR 1.42; CI 1.10–1.88). Patients who underwent middle fossa surgery, regardless of age, had an increased risk of post-surgery fall-related injury within 3 years of follow-up (HR 2.68; CI 1.06–6.81). We conclude that patients with vestibular schwannoma have a low risk of enduring fall-related injuries. Middle-aged patients with dizziness and fall-related injuries should be considered for a vestibular clinical evaluation. Our results highlight the importance of rehabilitation in avoiding future fall-related injuries among patients undergoing middle fossa surgery. [ABSTRACT FROM AUTHOR]

Incidence and survival of breast cancer, the most common cancer among women, have been increasing, leaving survivors at risk of aging-related health conditions. In this matched cohort study, we examined frailty risk with the Hospital Frailty Risk Score among breast cancer survivors (n  = 34,900) and age-matched comparison subjects (n  = 290,063). Women born in 1935–1975, registered in the Swedish Total Population Register (1991–2015), were eligible for inclusion. Survivors had a first breast cancer diagnosis in 1991–2005 and survived ≥5 years after initial diagnosis. Death date was determined by linkage to the National Cause of Death Registry (through 2015). Cancer survivorship was weakly associated with frailty (subdistribution hazard ratio (SHR) = 1.04, 95% confidence interval (CI): 1.00, 1.07). In age-stratified models, those diagnosed at younger ages (<50 years) had higher risk of frailty (SHR = 1.12, 95% CI: 1.00, 1.24) than those diagnosed at ages 50–65 (SHR = 1.03, 95% CI: 0.98, 1.07) or >65 (SHR = 1.09, 95% CI: 1.02, 1.17) years. Additionally, there was increased risk of frailty for diagnoses in 2000 or later (SHR = 1.15, 95% CI: 1.09, 1.21) compared with before 2000 (SHR = 0.97, 95% CI: 0.93, 1.17). This supports work from smaller samples showing that breast cancer survivors have increased frailty risk, particularly when diagnosed at younger ages. [ABSTRACT FROM AUTHOR]

Background and Purpose: The First-time Injurious Fall (FIF) screening tool was created to identify fall risk in community-living older men and women, who may be targets for primary preventive interventions. The FIF tool consists of 3 self-reported questions and 1 physical test (1-leg standing balance). The purpose of this study was to examine the predictive ability of the FIF tool and a modified FIF tool (in which 1-leg standing is replaced by self-reported balance) for first-time injurious falls. Methods: A cohort of 1194 community-living people 60 years and older from the Swedish National Study on Aging and Care in Kungsholmen (SNAC-K), Sweden, was followed longitudinally for 5 years. Data on injurious falls were collected from registered data and were defined as receipt of care after a fall. The predictive ability of the FIF tool and the m-FIF tool was explored using Harrell's C statistic, stratified by sex. Results and Discussion: The injurious fall rate per 1000 person-years was 54.9 (95% CI: 47.22-63.78) for women and 36.3 (95% CI: 28.84-45.78) for men. The predictive ability for women and men according to Harrell's C statistic was 0.70 and 0.71 for the FIF tool and the m-FIF tool. The predictive ability was 0.70 and 0.69 for 1-leg standing, and 0.65 and 0.60 for self-reported balance problems. Conclusions: The m-FIF tool presented similar predictive ability as the FIF tool regarding first-time injurious falls. This finding could extend the usefulness of the tool to other settings, such as to electronic health (eHealth). A quickly and easily administered screening tool can help physical therapists to identify people with a high risk of falling who may need to undergo a more comprehensive fall risk assessment.

Background Aging is the primary risk factor for frailty, which is defined as an inability to respond to acute or chronic stressors. Individuals are living longer with greater multimorbidity, but there is a paucity of evidence examining frailty across birth cohorts and ages. Methods We investigated frailty prevalence and its association with mortality at ages 75, 85, and 95 in the 1895–1945 birth cohorts in Sweden with data from population registries. Frailty was assessed with the Hospital Frailty Risk Score (HFRS). Results We observed that frailty increased with increasing age and that it has become more common in more recent birth cohorts. At age 75, the percent frail in the Total Population Register increased from 1.1% to 4.6% from birth cohorts 1915–1945, corresponding to calendar years 1990–2020. At age 85, the percentage of frail increased from 3.5% to 11.5% from birth cohorts 1905–1935, and at age 95 from birth cohorts 1895–1925, from 4.7% to 18.7%. Our results show that the increase was primarily driven by an increase in the distribution of individuals with scores in the highest quartile of HFRS, while the bottom 3 quartiles remained relatively stable across birth cohorts. Women accounted for a greater distribution of the overall population and frail population, though these disparities decreased over time. Despite increasing levels of frailty, the relationship between frailty and mortality did not change over time, nor did it differ by sex. Conclusion Increased frailty with improved survival points to a chronic condition that could be intervened upon. [ABSTRACT FROM AUTHOR]

Background and purpose -- Waiting time to surgery is a modifiable risk factor in hip fracture surgery. However, there is no consensus regarding the acceptable duration of waiting time. We used the Swedish Hip Fracture Register RIKSHÖFT and 3 administrative registers to explore the association between time to surgery and adverse outcomes after discharge. Patients and methods -- 63,998 patients ≥ 65 years, admitted to a hospital between January 1, 2012, and August 31, 2017 were included. Time to surgery was divided into < 12, 12-24, and > 24 hours. Diagnoses investigated were atrial fibrillation/flutter (AF), congestive heart failure (CHF), pneumonia, and "acute ischemia" (a combination of stroke/ intracranial bleeding, myocardial infarction, and acute kidney injury). Crude and adjusted survival analyses were performed. Time spent in hospital following the initial hospitalization was described for the 3 groups. Results -- Waiting > 24 hours was associated with an increased risk of AF (HR 1.4, 95%CI 1.2-1.6), CHF (HR 1.3, CI 1.1-1.4) and "acute ischemia" (HR 1.2, CI 1.01-1.3). However, stratifying for ASA grade revealed that these associations were present only in patients with ASA 3-4. There was no association between waiting time and pneumonia after the initial hospitalization (HR 1.1, CI 0.97-1.2), but one was found with pneumonia during hospital stay OR 1.2 (CI 1.1-1.4). Time in hospital after the initial hospitalization was similar over the waiting time groups. Conclusion -- The associations between waiting > 24 hours for hip fracture surgery and AF, CHF, and acute ischemia suggest that shorter waiting time may reduce adverse outcomes for the sicker patients.

In this study, we examined the impact of hip fractures on trajectories of home care, nursing home residence, and mortality among individuals aged 65 years or more and explored the impacts of living arrangements, cohabitation, frailty, and socioeconomic position on these trajectories. Based on a linkage of nationwide Swedish population registers, our study included 20,573 individuals with first hip fracture in 2014–2015. Care trajectories during the 2 years following the fracture were visualized and compared with those of 2 hip-fracture–free control groups drawn from the general population: age- and sex-matched controls and health-matched controls identified through propensity score matching. Multistate modeling was employed to identify sociodemographic and health-related factors associated with care trajectories among hip fracture patients. We found that hip fracture patients already had worse health than the general population before their fracture. However, when controlling for prefracture health, hip fractures still had a considerable impact on use of elder-care services and mortality. Comparisons with the health-matched controls suggest that hip fractures have an immediate, yet short-term, impact on care trajectories. Long-term care needs are largely attributable to poorer health profiles independent of the fracture itself. This emphasizes the importance of adequate comparison groups when examining the consequences of diseases which are often accompanied by other underlying health problems. [ABSTRACT FROM AUTHOR]

Background: Hospital length of stay (LoS) is believed to be associated with higher mortality in hip fracture patients; however, previous research has shown conflicting results. We aimed to explore the association between LoS and 4-month mortality in different groups of hip fracture patients.Methods: The study population in this Swedish register-based cohort study was 47 811 patients 65 years or older with a first hip fracture during 2012-2016, followed up for 4 months after discharge. LoS was categorized by cubic splines, and the association between LoS and mortality was analyzed with Cox regression models, adjusted for sociodemographic- and health-related factors.Results: Mean LoS was 11.2 ± 5.9 days and 12.3% of the patients died within 4 months. Both a shorter and a longer LoS, compared to the reference 9-12 days, were associated with higher mortality (hazard ratio [95% confidence interval]): 2-4 days 2.15 (1.98-2.34), 5-8 days 1.58 (1.47-1.69), and 24+ days 1.29 (1.13-1.46). However, in fully adjusted models, only the association with a long LoS remained: 13-23 days 1.08 (1.00-1.17) and 24+ days 1.42 (1.25-1.61). Stratifying by living arrangement revealed that the increased risk for a short LoS was driven by the group living in care homes. For patients living at home, a short LoS was associated with lower risk: 0.65 (0.47-0.91) and 0.85 (0.74-0.98) for 2-4 and 5-8 days, respectively.Conclusions: A long LoS after a hip fracture is associated with increased 4-month mortality risk even after considering patient characteristics. The association between mortality and a short LoS, however, is explained by individuals coming from care homes (with higher mortality risk), being discharged early. [ABSTRACT FROM AUTHOR]

Background and purpose -- Internal fixation (IF) has been the standard procedure for undisplaced femoral neck fractures (FNFs). However, there is a changing trend towards hip replacement (HR). Yet there is a knowledge gap regarding the benefits of this surgical method. We investigated functional outcomes in patients ≥ 70 years following HR compared to IF for undisplaced FNFs. Patients and methods -- Patients ≥ 70 years with undisplaced FNF registered in the Swedish National Hip Fracture Registry (SHR) who underwent either IF or HR (hemiarthroplasty [HA)] or total hip arthroplasty [THA]) were investigated in terms of 1-year survival and proportion of reoperation. In a subsample with 4-month follow-up data (n = 3,623), pain, changes in living status, and physical function were additionally analyzed. Results -- 7,758 patients were included with a mean age of 85 years. 93% of the patients were operated on with IF, 5% with HA, and 2% with THA. Patients with THA more often lived independently and were able to walk outdoors, both before and after the hip fracture. The IF and HA groups were similar in baseline characteristics, and in functional and survival outcomes. The THA group had a 54% lower adjusted risk of 1-year mortality. The proportion of reoperations within 1 year was 9.5% for IF, 5.3% for HA, and 7% for THA. Interpretation -- The pre-fracture difference in health and function between patients operated on with IF, HA, and THA maked it difficult to compare outcomes of the 2 methods. Decision on surgical method must be taken on an individual level, considering patients' well-being and allocation of resources. [ABSTRACT FROM AUTHOR]

Background: The impact of falls on cognitive function is unclear. We explored whether injurious falls are associated with cognitive decline in older adults, and evaluated the role of changes in psychological and physical health as mediators of such association.Methods: This prospective study involved 2267 community-dwelling participants in the Swedish National study on Aging and Care in Kungsholmen (≥60 years). Data on injurious falls (ie, falls requiring medical attention) during each 3-year time interval of follow-up were obtained from national registers. Assessment of cognitive function (Mini-Mental State Examination), depressive mood (Montgomery-Åsberg Depression Rating Scale), and physical performance (walking speed) were carried out every 3 or 6 years over a 12-year follow-up. The association between falls and cognition was estimated through linear mixed-effects models, and the mediating role of changes in depressive mood and physical performance was tested using mediation analysis.Results: After adjusting for potential confounders, individuals who experienced injurious falls had a greater annual decline in Mini-Mental State Examination in the subsequent time interval (β = -1.49, 95% CI: -1.84; -1.13), than those who did not. The association increased with the occurrence of ≥2 falls (β = -2.13, 95% CI: -2.70; -1.56). Worsening of walking speed and depressive mood explained around 26% and 8%, respectively, of the association between falls and cognitive decline.Conclusions: Injurious falls are associated with greater cognitive decline, and this association is partly mediated by worsening of physical performance and, in a lesser extent, of depressive mood. These findings suggest that physical deficits and low mood are potential therapeutic targets for mitigating the association between falls and cognitive decline. [ABSTRACT FROM AUTHOR]

OBJECTIVES To identify sex‐specific associations between risk factors and injurious falls over the short (<4 years) and long (4–10 years) term. DESIGN Longitudinal cohort study between 2001 and 2011. SETTING Swedish National Study on Aging and Care, Kungsholmen, Sweden. PARTICIPANTS Community‐dwelling adults aged 60 and older (N = 3,112). MEASUREMENTS An injurious fall was defined as a fall that required inpatient or outpatient care. Information was collected on participant and exposure characteristics using structured interviews, clinical examinations, and physical function tests at baseline. RESULTS: The multivariate model showed that, in the short term, living alone (hazard ratio (HR)=1.83, 95% confidence interval (CI)=1.13–2.96), dependency in instrumental activities of daily living (IADLs) (HR=2.59, 95% CI=1.73–3.87), and previous falls (HR=1.71, 95% CI=1.08–2.72) were independently associated with injurious falls in women. Low systolic blood pressure (HR=1.96, 95% CI=1.04–3.71), impaired chair stands (HR=3.00, 95% CI=1.52–5.93), and previous falls (HR=2.81, 95% CI=1.32–5.97) were associated with injurious falls in men. Long‐term risk factors were underweight (HR=2.03, 95% CI=1.40–2.95), cognitive impairment (HR=1.49, 95% CI=1.08–2.06), fall‐risk increasing drugs (HR=1.67, 95% CI=1.27–2.20 for ≥2 drugs), and IADL dependency (HR=1.58, 95% CI=1.32–5.97) for women and smoking (HR=1.71, 95% CI=1.03–2.84), heart disease (HR=2.20, 95% CI=1.5–3.24), impaired balance (HR=1.68, 95% CI=1.08–2.62), and a previous fall (HR=3.61, 95% CI=1.98–6.61) for men. CONCLUSION: Men and women have different fall risk profiles, and these differences should be considered when developing preventive strategies. Some risk factors were more strongly predictive of injurious falls over shorter than longer periods and vice versa, suggesting that it may be possible to identify older men and women at short‐ and long‐term risk of injurious falls.

Background a trend towards decline in disability has been reported in older adults, but less is known about corresponding temporal trends in measured physical functions. Objective to verify these trends during 2001–16 in an older Swedish population. Methods functional status was assessed at three occasions: 2001–04 (n = 2,266), 2007–10 (n = 2,033) and 2013–16 (n = 1,476), using objectively measured balance, chair stands and walking speed. Point prevalence was calculated and trajectories of change in impairment/vital status were assessed and were sex-adjusted and age-stratified: 66; 72; 78; 81 and 84; 87 and 90. Results point prevalence of impairment was significantly lower at the 2013–16 assessment than the 2001–04 in chair stand amongst age cohorts 78–90 years, and in walking speed amongst age cohorts 72–84 years (P < 0.05), but not significantly different for balance. The prevalence remained stable between 2001–04 and 2007–10, while the decrease in chair stands and walking speed primarily occurred between 2007–10 and 2013–16. Among persons unimpaired in 2007–10, the proportion of persons who remained unimpaired in 2013–16 tended to be higher, and both the proportion of persons who became impaired and the proportion of persons who died within 6 years tended to be lower, relative to corresponding proportions for persons unimpaired in 2001–04. Overall, there were no corresponding changes for those starting with impairment. Conclusions our results suggest a trend towards less functional impairment in older adults in recent years. The improvements appear to be driven by improved prognosis amongst those without impairments rather than substantial changes in prognosis for those with impairments. [ABSTRACT FROM AUTHOR]

Background: Although falls in older adults are related to multiple risk factors, these factors have commonly been studied individually. We aimed to identify risk profiles for injurious falls in older adults by detecting clusters of established risk factors and quantifying their impact on fall risk.Methods: Participants were 2,566 people, aged 60 years and older, from the population-based Swedish National Study on Aging and Care in Kungsholmen. Injurious falls was defined as hospitalization for or receipt of outpatient care because a fall. Cluster analysis was used to identify aggregation of possible risk factors including chronic diseases, fall-risk increasing drugs (FRIDs), physical and cognitive impairments, and lifestyle-related factors. Associations between the clusters and injurious falls over 3, 5, and 10 years were estimated using flexible parametric survival models.Results: Five clusters were identified including: a "healthy", a "well-functioning with multimorbidity", a "well-functioning, with multimorbidity and high FRID consumption", a "physically and cognitively impaired", and a "disabled" cluster. The risk of injurious falls for all groups was significantly higher than for the first cluster of healthy individuals in the reference category. Hazard ratios (95% confidence intervals) ranged from 1.71 (1.02-2.66) for the second cluster to 12.67 (7.38-21.75) for the last cluster over 3 years of follow-up. The highest risk was observed in the last two clusters with high burden of physical and cognitive impairments.Conclusion: Risk factors for injurious fall tend to aggregate, representing different levels of risk for falls. Our findings can be useful to tailor and prioritize clinical and public health interventions. [ABSTRACT FROM AUTHOR]

We aimed to examine to what extent blood pressure (BP) components are associated with injurious falls in older adults, and whether the possible associations differ by functional status (indicated by physical and cognitive impairment at baseline). This prospective cohort study included 3055 community-living participants of the Swedish National study on Aging and Care in Kungsholmen (aged ≥60 years). At baseline (2001–2004), we measured systolic BP (SBP) and diastolic BP (DBP), mean arterial pressure, pulse pressure (PP), and orthostatic hypotension. Physical function was assessed using tests of balance, chair stands, and walking speed. Cognitive function was assessed with the Mini-Mental State Examination. Injurious falls leading to inpatient or outpatient care during 3 and 10 years of follow-up were identified via patient registers. Data were analyzed using flexible parametric survival models adjusted for potential confounders. During the 10-year follow-up period in people without functional impairment, the multi-adjusted hazard ratios (HR) of injurious falls were 1.77 (95% CI 1.02–3.07) for having SBP <130 mmHg, 1.73 (95% CI 1.05–2.83) for having SBP ≥160 mmHg (vs. 130–139), and 1.46 (1.05–2.02) for having higher tertile of PP (vs. lower tertile). During the 3-year follow-up period in people with functional impairment, the multi-adjusted HR of injurious falls was 1.91 (95% CI 1.17–3.13) for having SBP <130 mmHg (vs. 130–139) and 0.74 (0.59–0.94) for having higher tertile of PP (vs. lower tertile). There was no significant association between BP components and injurious falls either in people without functional impairment during the 3-year follow-up period, or in people with functional impairment during the 10-year follow-up period. This large-scale Swedish study provides evidence that the associations between some specific components of BP and risk of injurious falls in older adults vary by functional status. This supports the view that a personalized approach to blood pressure management depending on functional status among older adults might be warranted in clinical settings. • Some blood pressure components are associated with injurious falls in older adults. • The risk of injurious falls in older adults may vary by functional status. • A personalized approach to blood pressure management might be warranted.

Aims: The primary aim of this study was to compare surgical methods (sliding hip screw (SHS) vs intramedullary nailing (IMN)) for trochanteric hip fracture in relation to death within 120 days after surgery and return to independent living. The secondary aim was to assess whether the associations between surgical method and death or ability to return to independent living varied depending on fracture subtype or other patient characteristics., Methods: A total of 27,530 individuals from the Swedish Hip Fracture Register RIKSHÖFT (SHR) aged ≥ 70 years, admitted to hospital between 1 January 2014 and 31 December 2019 with trochanteric hip fracture, were included. Within this cohort, 12,041 individuals lived independently at baseline, had follow-up information in the SHR, and were thus investigated for return to independent living. Death within 120 days after surgery was analyzed using Cox regression with SHS as reference and adjusted for age and fracture type. Return to independent living was analyzed using logistic regression adjusted for age and fracture type. Analyses were repeated after stratification by fracture type, age, and sex., Results: Overall, 2,171 patients (18%) who were operated with SHS and 2,704 patients (18%) who were operated with IMN died within 120 days after surgery. Adjusted Cox regression revealed no difference in death within 120 days for the whole group (hazard ratio 0.97 (95% CI 0.91 to 1.03)), nor after stratification by fracture type. In total, 3,714 (66%) patients who were operated with SHS and 4,147 (64%) patients who were operated with IMN had returned to independent living at follow-up. There was no significant difference in return to independent living for the whole group (odds ratio 0.95 (95% CI 0.87 to 1.03)), nor after stratification by fracture type., Conclusion: No overall difference was observed in death within 120 days or return to independent living following surgery for trochanteric hip fracture, depending on surgical method (SHS vs IMN) in this recent Swedish cohort, but there was a suggested benefit for SHS in subgroups of patients., Competing Interests: K.

Background: Frailty is an age-related health condition affecting an estimated 18% of older adults in Europe and past evidence has shown a relationship between socioeconomic factors and frailty. We examined population frailty trends and the association between frailty and 5-year mortality by education tertiles and income quartiles at ages 75, 85 and 95 in Swedish registry data., Methods: All Swedish residents born in 1895-1945 and in the Total Population Register from 1990 to 2020 were included. Frailty was assessed with the Hospital Frailty Risk Score (HFRS), which sums 109 weighted International Classification of Diseases (ICD codes), collected from the National Patient Register., Results: Regardless of education and income, frailty increased over time, though the association between frailty and 5-year mortality remained stable. Particularly in earlier birth cohorts, although the highest education and income levels had the highest mean HFRS scores, the lowest education and income levels accounted for greater proportions among the frail. These trends varied slightly by sex and age. Men and women had similar levels of frailty, but frailty was more strongly associated with mortality among men., Conclusion: Over time, education and income levels were more equally represented among the frail population in more recent years. More equitable distribution over time may suggest improvement in health disparities, though more work is needed. The overall increase in frailty and unchanged association with mortality indicates that additional research is needed to better understand how to best support the growing ageing population. This would then support the long-term viability of the healthcare system., Competing Interests: Competing interests: AW receives payment from Janssen Pharmaceutica NV for a separate collaboration., (© Author(s) (or their employer(s)) 2023.

In this study, we examined the impact of hip fractures on trajectories of home care, nursing home residence, and mortality among individuals aged 65 years or more and explored the impacts of living arrangements, cohabitation, frailty, and socioeconomic position on these trajectories. Based on a linkage of nationwide Swedish population registers, our study included 20,573 individuals with first hip fracture in 2014-2015. Care trajectories during the 2 years following the fracture were visualized and compared with those of 2 hip-fracture-free control groups drawn from the general population: age- and sex-matched controls and health-matched controls identified through propensity score matching. Multistate modeling was employed to identify sociodemographic and health-related factors associated with care trajectories among hip fracture patients. We found that hip fracture patients already had worse health than the general population before their fracture. However, when controlling for prefracture health, hip fractures still had a considerable impact on use of elder-care services and mortality. Comparisons with the health-matched controls suggest that hip fractures have an immediate, yet short-term, impact on care trajectories. Long-term care needs are largely attributable to poorer health profiles independent of the fracture itself. This emphasizes the importance of adequate comparison groups when examining the consequences of diseases which are often accompanied by other underlying health problems., (© The Author(s) 2022.
