Place of residence and risk of fracture in older people: a population-based study of over 65-year-olds in Cardiff

Decrease in incidence of proximal femur fractures in the elderly population during the Covid-19 pandemic: a case-control study

Background

The World Health Organization classified Covid-19 as a pandemic during the first months of 2020 as lockdown measures were implemented globally to mitigate the increasing incidence of Covid-19-related morbidity and mortality. The purpose of this study was to evaluate the effect of national lockdown measures on proximal femur fracture epidemiology. Our hypothesis was that due to the prolonged period of stay-at-home orders, we would observe a decrease in the incidence of proximal femur fractures during the years 2020–21.

Methods

A retrospective case–control study of 2784 hip fractures admitted to the emergency department at one hospital between January 1, 2010, and March 31, 2021, was conducted. Cases were stratified weekly, and an analysis was conducted comparing cases occurring during government-imposed lockdown periods of 2020–21 to corresponding periods during 2010–2019. Furthermore, the trend of cases throughout the year of 2020 was observed.

Results

Of all proximal femur fracture cases included, 2522 occurred between 2010–2019 and 261 during the Covid-19 period. There was no significant difference in age (81.95 vs. 82.09; P = 0.78) or gender (P = 0.12). There was a total decrease of 21.64% in proximal femur fracture per week during the entirety of the Covid-19 pandemic period compared to the previous years (3.64 ± 1.99 vs. 4.76 ± 0.83; P = 0.001). During all three lockdown periods, there was a significant decrease in proximal femur fracture cases per week (3.55 ± 2.60 vs. 4.87 ± 0.95; P = 0.04), and the most pronounced decrease occurred during the third lockdown period (2.89 ± 1.96 vs. 5.23 ± 1.18; P = 0.01).

Conclusion

We observed a total decrease in the number of proximal femur fractures occurring during the Covid-19 era compared to previous years and specifically a decrease of cases occurring during the government-imposed lockdown periods. The decrease in cases was more pronounced during the second and third lockdown periods.

Fall Patterns Predict Mortality After Hip Fracture in Older Adults, Independent of Age, Sex, and Comorbidities

Falls are the most frequent cause of hip fracture. We aimed to investigate whether specific fall patterns have predictive value for mortality after hip fracture. In this cohort study, data of individuals presented to the Severance Hospital, Seoul, Korea, between 2005 and 2019 due to fragility hip fracture (n = 1986) were analyzed. Fall patterns were defined as causes, activities leading to falls, and a combination of both, based on electronic medical records using pre-specified classification from a prior study on video-captured falls. Mean age of study subjects were 77 years (71% women) and 211 patients (10.6%) died during follow-up (median 544 days). Indoor falls at home had a higher mortality than outdoor falls (11.9 vs. 8.0%, p = 0.009). Among 16 fall patterns, incorrect weight shift while sitting down (adjusted hazard ratio [aHR] 4.03) or getting up (aHR 2.01), collapse during low-risk activity (aHR 2.39), and slipping while walking (aHR 2.90, p < 0.01 for all) were associated with increased mortality compared to outdoor falls, after adjustment for age, sex, and Charlson comorbidity index (CCI), constituting a high-risk pattern. High-risk fall patterns were associated with a higher risk of mortality (aHR 2.56, p < 0.001) than low-risk patterns (aHR 1.37, p = 0.080) and outdoor falls (referent; log rank p < 0.001), which improved mortality prediction when added to a base model including age, sex, and CCI (integrative area under receiver-operating characteristics curve 0.675 to 0.698, p < 0.001). Specific fall patterns were associated with higher mortality in older adults with hip fracture, independent of age, sex, and comorbidities.

Differences in the baseline characteristics, management and outcomes of patients with hip fractures depending on their pre-fracture place of residence: the Spanish National Hip Fracture Registry (RNFC) cohort

PURPOSE

One in four hip fracture patients comes from an aged care facility. This study aimed to compare the characteristics of these subjects with their community-dwelling counterparts at baseline, during hospitalization and 1-month post-fracture.

METHODS

We analyzed data from a cohort of older adults admitted with hip fractures to 75 Spanish hospitals, collected prospectively in the Spanish National Hip Fracture Registry between 2016 and 2018. We classified participants according to pre-fracture residence: community dwellers vs. aged care facilities residents. We collected demographic records at baseline, along with variables relating to in-hospital evolution and discharge to geriatric rehabilitation units. Patients or relatives were interviewed at 1-month follow-up.

RESULTS

Out of 18,262 patients, 4,422 (24.2%) lived in aged care facilities. Aged care facilities residents were older (median age: 89 vs. 86 years), less mobile (inability to walk independently: 20.8% vs. 9.4%) and had more cognitive impairment (Pfeiffer's SPMSQ > 3, 75.3% vs. 34.8%). They were more likely to receive conservative treatment (5.4% vs. 2.0%) and less likely to be mobilized early (58.2% vs. 63.0%). At discharge, they received less vitamin D supplements (68.5% vs. 72.4%), less anti-osteoporotic medication (29.3% vs. 44.3%), and were referred to geriatric rehabilitation units less frequently (5.4% vs. 27.5%). One-month post-fracture, 45% of aged care facilities residents compared to 28% of community dwellers experienced a severe gait decline. Aged care facilities residents had a higher one-month mortality (10.6% vs. 6.8%).

CONCLUSION

Hip fracture patients from aged care facilities are more vulnerable than their community-dwelling peers and are managed differently both during hospitalization and at discharge. Gait decline is disproportionately higher among those admitted from aged care.

The effect of frailty on outcomes of surgically treated hip fractures in older people

BACKGROUND

Hip fractures are associated with mortality, disability, and loss of independence in older adults. While several risk factors associated with poor outcomes following a hip fracture have been identified, the effect of frailty status prior to hip fracture is not well established.

AIM

To examine the associations of frailty with mortality, change in activities of daily living (ADL) limitations, and transition to permanent residential aged care in older people following a hip fracture.

METHODS

A retrospective cohort study was conducted on people aged 65 years and older with a surgically treated hip fracture between 2003 and 2015. Frailty was estimated using a cumulative deficit-based frailty index and categorized into quartiles. Cox multivariable regression, logistic regression, and Fine-Gray multivariable regression models estimated associations of frailty with mortality, ADL limitations, and entry into permanent residential aged care, respectively. Hazard ratios (HR), odds ratios (OR), subdistribution hazard ratios (SHR), and 95% confidence intervals (95%CI) are reported.

RESULTS

Out of 4771 individuals with hip fractures, 75.6% were female and the median age was 86 (interquartile range 82-90) years old. The two-year survival of patients following hip fracture was 43.7% (95%CI 40.9-46.7%) in those in the highest quartile of frailty, compared to 54.4% (95%CI 51.8-57.2%) for those in the lowest quartile (HR = 1.25, 95%CI 1.11-1.41, p < 0.001). No associations between pre-fracture frailty and post-fracture ADL limitations were observed. Additionally, no association of frailty with transition to permanent residential aged care for patients living in the community (n = 1361) was observed (SHR = 0.98, 95%CI 0.81-1.18, p = 1.000).

CONCLUSIONS

Older patients with the highest level of frailty had an increased risk of mortality after hip fracture. Consideration for appropriate clinical interventions, including fall and frailty prevention measures, may be appropriate for this identified group of vulnerable individuals.

Rehabilitation After Hip Fracture for Nursing Home Residents: A Controlled Feasibility Trial

BACKGROUND

This study compared functional outcomes at 3 months after hip fracture surgery between nursing home residents participating in a 10-week outreach rehabilitation program and those receiving usual care. Function, health-related quality of life, and mortality were also compared over 12 months, and outreach program feasibility was assessed.

METHODS

A feasibility trial was undertaken in Canadian nursing homes; of 77 participants, 46 were allocated to Outreach and 31 to Control prior to assessing function or cognition. Outreach participants received 10 weeks of rehabilitation (30 sessions), and Control participants received usual posthospital fracture care in their nursing homes. The primary outcome was the Functional Independence Measure Physical Domain (FIMphysical) score 3 months post-fracture; we also explored FIM Locomotion and Mobility. Secondary outcomes were FIM scores, EQ-5D-3L scores, and mortality over 12 months. Program feasibility was also evaluated.

RESULTS

The mean age was 88.7 ± 7.0 years, 55 (71%) were female, and 58 (75%) had severe cognitive impairment with no significant group differences (p > .14). Outreach participants had significantly higher FIM Locomotion than usual care (p = .02), but no significant group differences were seen in FIMphysical or FIM Mobility score 3 months post-fracture. In adjusted analyses, Outreach participants reported significant improvements in all FIM and EQ-5D-3L scores compared with Control participants over 12 months (p < .05). Mortality did not differ by group (p = .80). Thirty (65%) Outreach participants completed the program.

CONCLUSIONS

Our feasibility trial demonstrated that Outreach participants achieved better locomotion by 3 months post-fracture compared with participants receiving usual postfracture care; benefits were sustained to 12 months post-fracture. In adjusted analyses, Outreach participants also showed sustained benefits in physical function and health-related quality of life.

Evaluating the effects of an exercise program (Staying UpRight) for older adults in long-term care on rates of falls: study protocol for a randomised controlled trial

Background

Falls are two to four times more frequent amongst older adults living in long-term care (LTC) than community-dwelling older adults and have deleterious consequences. It is hypothesised that a progressive exercise program targeting balance and strength will reduce fall rates when compared to a seated exercise program and do so cost effectively.

Methods/design

This is a single blind, parallel-group, randomised controlled trial with blinded assessment of outcome and intention-to-treat analysis. LTC residents (age ≥ 65 years) will be recruited from LTC facilities in New Zealand. Participants (n = 528 total, with a 1:1 allocation ratio) will be randomly assigned to either a novel exercise program (Staying UpRight), comprising strength and balance exercises designed specifically for LTC and acceptable to people with dementia (intervention group), or a seated exercise program (control group). The intervention and control group classes will be delivered for 1 h twice weekly over 1 year. The primary outcome is rate of falls (per 1000 person years) within the intervention period.

Secondary outcomes will be risk of falling (the proportion of fallers per group), fall rate relative to activity exposure, hospitalisation for fall-related injury, change in gait variability, volume and patterns of ambulatory activity and change in physical performance assessed at baseline and after 6 and 12 months. Cost-effectiveness will be examined using intervention and health service costs.

The trial commenced recruitment on 30 November 2018.

Discussion

This study evaluates the efficacy and cost-effectiveness of a progressive strength and balance exercise program for aged care residents to reduce falls. The outcomes will aid development of evidenced-based exercise programmes for this vulnerable population.

Baseline and 1-year follow-up differences between hip-fracture patients admitted from nursing homes and the community. A cohort study on 509 consecutive patients (FONDA Cohort)

OBJECTIVE

To determine the clinical and functional differences at hospital admission and at 1 year after a hip fracture (HF) in nursing homes (NH) and community-dwelling (CD) patients.

METHODS

All patients with HF admitted to the orthogeriatric unit at a university hospital between January 2013 and February 2014 were prospectively included. Clinical and functional variables, and mortality were recorded during the hospital admission. The patients were contacted by telephone at 1 year to determine their vital condition and functional status.

RESULTS

A total of 509 patients were included, 116 (22.8%) of whom came from NH. Compared with the CD patients, the NH patients had higher surgical risk (ASA ≥3: 83.6% vs. 66.4%, P<.001), poorer theoretical vital prognosis (Nottingham Profile ≥5: 98.3% vs. 56.6%, P<.001), higher rate of previous functional status (median Barthel index: 55 [IQR, 36-80] vs. 90 [IQR, 75-100], P<.001), poorer mental status (Pfeiffer's SPMSQ>2: 74.1% vs. 40.2%, P<.001), and a higher rate of sarcopenia (24.3% vs. 15.2%, P<.05). There were no differences in in-hospital or at 1-year mortality. At 1 year, NH patients recovered their previous walking capacity at a lower rate (38.5% vs. 56.2%, P<.001).

CONCLUSIONS

Among the patients with HF treated in an orthogeriatric unit, NH patients had higher, surgical risk, functional and mental impairment, and a higher rate of sarcopenia than CD patients. At 1 year of follow-up, NH patients did not have higher mortality, but they recovered their previous capacity for walking less frequently.

Osteoporosis and the Ageing Skeleton

Osteoporosis is a "skeletal disorder characterized by compromised bone strength predisposing a person to an increased risk of fracture" which, in light of demographic change, is becoming an increasing burden on health care worldwide. Increasing age and female gender are associated with the condition, although a wider range of clinical risk factors are being used increasingly to identify those at risk of osteoporosis and its most important sequelae, fracture.While osteoporosis and fracture have long been associated with women in the post-menopausal age, fracture incidence increases because of the ageing of our population. Interventions to abate the progression of osteoporosis and to prevent fractures must focus on the old and the very old. Evidence associating nutritional factors, particularly calcium and vitamin D are reviewed as are the association of falls risk with fracture and the potential for interventions to prevent falls. Finally, the assessment of frailty in the oldest old, associated sarcopenia and multi-morbidity are considered in the evaluation of fall and fracture risk and the management of osteoporosis in the ninth decade of life and beyond.

Incidence Rates of and Mortality after Hip Fracture among German Nursing Home Residents

Little is known about hip fracture rates and post-fracture mortality among nursing home residents. This retrospective cohort study examined incidence rates (IR) of and mortality after hip fracture in this population focusing on sex differences. A cohort of >127,000 residents ≥65 years, newly admitted to German nursing homes between 2010 and 2014 were used to calculate age-, sex-, care-need- and time after admission-specific IR. To determine mortality, the Kaplan-Meier-method was applied. Using Cox regression, we studied mortality and estimated time-dependent hazard ratios (HRs). For this purpose, to each person with a hip fracture, one resident without a hip fracture was matched by sex, age and care-need using risk-set sampling. 75% were women (mean age: 84.0 years). During 168,588 person-years (PY), 8537 residents with at least one hip fracture were observed. The IR for women and men were 52.9 and 42.5/1000 PY. For both sexes, IR increased with rising age and decreased with increasing care-level. IR were highest in the first months after admission and subsequently declined afterwards. The impact of hip fractures on mortality was time-dependent. Mortality of residents with hip fracture was highest in the first two months after fracture compared to those without (HR): 2.82; 95% CI 2.57–3.11) and after six months, no differences were found (HR: 1.10; 95% CI 0.98–1.22) Further research should always include analyses stratified by sex, age and time period after admission.

Home or foster home care versus institutional long-term care for functionally dependent older people

BACKGROUND

Changing population demographics have led to an increasing number of functionally dependent older people who require care and medical treatment. In many countries, government policy aims to shift resources into the community from institutional care settings with the expectation that this will reduce costs and improve the quality of care compared.

OBJECTIVES

To assess the effects of long-term home or foster home care versus institutional care for functionally dependent older people.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) via the Cochrane Library, MEDLINE, Embase, CINAHL, and two trials registers to November 2015.

SELECTION CRITERIA

We included randomised and non-randomised trials, controlled before-after studies and interrupted time series studies complying with the EPOC study design criteria and comparing the effects of long-term home care versus institutional care for functionally dependent older people.

DATA COLLECTION AND ANALYSIS

Two reviewers independently extracted data and assessed the risk of bias of each included study. We reported the results narratively, as the substantial heterogeneity across studies meant that meta-analysis was not appropriate.

MAIN RESULTS

We included 10 studies involving 16,377 participants, all of which were conducted in high income countries. Included studies compared community-based care with institutional care (care homes). The sample size ranged from 98 to 11,803 (median N = 204). There was substantial heterogeneity in the healthcare context, interventions studied, and outcomes assessed. One study was a randomised trial (N = 112); other included studies used designs that had potential for bias, particularly due lack of randomisation, baseline imbalances, and non-blinded outcome assessment. Most studies did not select (or exclude) participants for any specific disease state, with the exception of one study that only included patients if they had a stroke. All studies had methodological limitations, so readers should interpret results with caution.It is uncertain whether long-term home care compared to nursing home care decreases mortality risk (2 studies, N = 314, very-low certainty evidence). Estimates ranged from a nearly three-fold increased risk of mortality in the homecare group (risk ratio (RR) 2.89, 95% confidence interval (CI) 1.57 to 5.32) to a 62% relative reduction (RR 0.38, 95% CI 0.17 to 0.61). We did not pool data due to the high degree of heterogeneity (I2 = 94%).It is uncertain whether the intervention has a beneficial effect on physical function, as the certainty of evidence is very low (5 studies, N = 1295). Two studies reported that participants who received long-term home care had improved activities of daily living compared to those in a nursing home, whereas a third study reported that all participants performed equally on physical function.It is uncertain whether long-term home care improves happiness compared to nursing home care (RR 1.97, 95% CI 1.27 to 3.04) or general satisfaction because the certainty of evidence was very low (2 studies, N = 114).The extent to which long-term home care was associated to more or fewer adverse health outcomes than nursing home care was not reported.It is uncertain whether long-term home care compared to nursing home care decreases the risk of hospital admission (very low-certainty evidence, N = 14,853). RR estimates ranged from 2.75 (95% CI 2.59 to 2.92), showing an increased risk for those receiving care at home, to 0.82 (95% CI 0.72 to 0.93), showing a slightly reduced risk for the same group. We did not pool data due to the high degree of heterogeneity (I2 = 99%).

AUTHORS' CONCLUSIONS

There are insufficient high-quality published data to support any particular model of care for functionally dependent older people. Community-based care was not consistently beneficial across all the included studies; there were some data suggesting that community-based care may be associated with improved quality of life and physical function compared to institutional care. However, community alternatives to institutional care may be associated with increased risk of hospitalisation. Future studies should assess healthcare utilisation, perform economic analysis, and consider caregiver burden.

Do Patients Taking Warfarin Experience Delays to Theatre, Longer Hospital Stay, and Poorer Survival After Hip Fracture?

BACKGROUND

Patients sustaining a fractured neck of the femur are typically of advanced age with multiple comorbidities. As a consequence, the proportion of these patients receiving warfarin therapy is approximately 10%. There are currently few studies investigating outcomes in this subset of patients.

QUESTIONS/PURPOSES

The purpose of this study was to assess the association between warfarin therapy and time to surgery, length of hospital stay, and survival in patients sustaining a fractured neck of the femur.

METHODS

Data for 2036 patients admitted to our center between July 2009 and July 2014 with a fractured neck of the femur were extracted from the National Hip Fracture Database. Fifty-seven patients received no surgical treatment and were excluded from analysis. Multivariable ordinary least squares regression was performed to test the association between warfarin treatment on time to surgery and length of stay, and Cox proportional hazards to test followup survival. Variables included in the regression model were age, sex, American Society of Anesthesiologists (ASA) score, admission Abbreviated Mental Test Score (AMTS), fracture type, operation type, and premorbid Work Ability Index (WAI). One hundred fifty-two of 1979 surgically treated patients (8%) were receiving warfarin therapy at the time of admission.

RESULTS

After controlling for age, sex, ASA score, AMTS, fracture type, operation type, and WAI, we found that patients taking warfarin were less likely to go to surgery by 36 hours (odds ratio [OR], 0.20; 95% CI, 0.14-0.30), and less likely to go to surgery by 48 hours (OR, 0.17; 95% CI, 0.11-0.24). Patients taking warfarin had a longer length of stay (median, 15 days; interquartile range [IQR], 12-22 days) compared with patients not taking warfarin (median, 13 days; IQR, 9-20 days; p < 0.001). Survival analysis to June 2015 showed a higher mortality for patients taking warfarin (12-month survival, 66% vs 76%; hazard ratio, 1.57; 95% CI, 1.21-2.04; p < 0.001).

CONCLUSIONS

After controlling for multiple prognostic factors such as age, ASA score, AMTS, and WAI, warfarin therapy at the time of injury is associated with increased time to surgery, length of stay, and decreased survival. This study highlights the need to view warfarin therapy as a 'red flag' in patients presenting with a fractured neck of the femur. Preoperatively, prompt warfarin reversal together with adequate investigation and optimization of the patient should ensure timely, safe surgery. Early involvement of the anesthesia team should ensure an appropriate level of postoperative care for these patients.

LEVEL OF EVIDENCE

Level III, therapeutic study.

Understanding Mortality of Femoral Fractures Following Low-Impact Trauma in Persons With and Without Care Need

OBJECTIVES

Persons with osteoporotic fracture history are subject to an increased risk for subsequent fractures and mortality. The aim of this retrospective study was to investigate the impact of a previous osteoporotic low-impact (fragility) index fracture (eg, forearm, lower leg) on mortality of a subsequent femoral fracture.

DESIGN

Retrospective cohort study.

PARTICIPANTS/MEASUREMENTS

Claims data of a German health insurance agency including >1.2 million insurants aged 65 years or older and observed between 2004 and 2009.

METHODS

A multistate model was developed handling index fractures and care need as time-dependent exposures, while age was chosen as the underlying time scale. Excess risks were expressed as differences in cause-specific hazards. Nelson-Aalen estimates were used for their nonparametric estimation. Time-simultaneous statistical inference was based on confidence bands provided by wild bootstrap resampling.

RESULTS

Excess femoral fracture risk increased with progressive age and was highest in persons with care need. It was observed starting from an age of 79 years in women and 85 years in men onward. A prior index fracture increased mortality after a femoral fracture by increasing femoral fracture risk, while leaving the hazard of death after a subsequent femoral fracture unchanged.

CONCLUSIONS

The results indicated that increased mortality of a subsequent femoral fracture is not triggered by an intrinsically increased mortality hazard but an increased femoral fracture incidence.

Comparative risk of hip fractures in elderly nursing home patients with depression using paroxetine and other selective serotonin reuptake inhibitors

AIM

To evaluate comparative safety of paroxetine and other selective serotonin reuptake inhibitors (SSRIs) for the risk of hip fractures.

PATIENTS & METHODS

A propensity score-matched retrospective cohort study was conducted using 2007-2010 Minimum Data Set linked Medicare data. Robust Cox proportional hazards model was used to evaluate the risk of hip fractures in depressed elderly nursing home residents.

RESULTS

Cox analysis did not find any significant difference in the risk of hip fractures for the paroxetine users (hazard ratio: 1.09; 95% CI: 0.91-1.32) when compared with other SSRIs. Results from the sensitivity analysis supported the main findings.

CONCLUSION

There was no differential risk of hip fractures between paroxetine and other SSRIs. Future studies are needed to evaluate other anticholinergic effects of paroxetine.

Incidence of Hip Fracture in U.S. Nursing Homes

BACKGROUND

Hip fractures are associated with significant morbidity and mortality in the nursing home. Our objective was to describe the incidence rate (IR) of hip fracture according to age, sex, and race in a nationwide sample of long-stay nursing home residents.

METHODS

Using 2007-2010 Medicare claims data linked with the Minimum Data Set, we identified 892,837 long-stay residents (≥100 days in the same nursing facility) between May 1, 2007 and April 30, 2008. Hip fractures were defined using Part A diagnostic codes (ICD-9). Residents were followed from the date they became a long-stay resident until the first event of death, discharge, hip fracture, or 2 years of follow-up.

RESULTS

Mean age was 84 years (range 65-113 years), and 74.5% were women. 83.9% were white and 12.0% were black. The overall IR of hip fracture was 2.3/100 person years. The IR was similar in men and women across age groups. The IR of hip fracture was highest in Native Americans aged 85 years or older (3.7/100 person years), in whites (2.6/100 person years), and during the first 100 days of institutionalization (2.7/100 person years). IRs of hip fracture were lowest in blacks (1.3/100 person years).

CONCLUSIONS

In nursing home residents surviving 100 days or more in a facility, the incidence of hip fracture is high, particularly among older white, Native American, and newly admitted residents. This is the first nationwide study to provide sex- and age-specific estimates among U.S. nursing home residents, and it underscores the magnitude of the problem.

Comparative trends in incident fracture rates for all long-term care and community-dwelling seniors in Ontario, Canada, 2002-2012

SUMMARY

In this population-based study, we compared incident fracture rates in long-term care (LTC) versus community seniors between 2002 and 2012. Hip fracture rates declined more rapidly in LTC than in the community. An excess burden of fractures occurred in LTC for hip, pelvis, and humerus fractures in men and hip fractures only in women.

INTRODUCTION

This study compares trends in incident fracture rates between long-term care (LTC) and community-dwelling seniors ≥65 years, 2002-2012.

METHODS

This is a population-based cohort study using administrative data. Measurements were age/sex-adjusted incident fracture rates and rate ratios (RR) and annual percent change (APC).

RESULTS

Over 11 years, hip fracture rates had a marked decline occurring more rapidly in LTC (APC, -3.49 (95% confidence interval (CI), -3.97, -3.01)) compared with the community (APC, -2.93 (95% CI, -3.28, -2.57); p < 0.05 for difference in slopes). Humerus and wrist fracture rates decreased; however, an opposite trend occurred for pelvis and spine fractures with rates increasing over time in both cohorts (all APCs, p < 0.05). In 2012, incident hip fracture rates were higher in LTC than the community (RRs: women, 1.55 (95% CI, 1.45, 1.67); men, 2.18 (95% CI, 1.93, 2.47)). Higher rates of pelvis (RR, 1.48 (95% CI, 1.22, 1.80)) and humerus (RR, 1.40 (95% CI, 1.07, 1.84)) fractures were observed in LTC men, not women. In women, wrist (RR, 0.76 (95% CI, 0.71, 0.81)) and spine (RR, 0.52 (95% CI, 0.45, 0.61)) fracture rates were lower in LTC than the community; in men, spine (RR, 0.75 (95% CI, 0.57, 0.98) but not wrist fracture (RR, 0.91 (95% CI, 0.67, 1.23)) rates were significantly lower in LTC than the community.

CONCLUSION

Previous studies in the community have shown declining hip fracture rates over time, also demonstrated in our study but at a more rapid rate in LTC. Rates of humerus and wrist fractures also declined. An excess burden of fractures in LTC occurred for hip fractures in women and for hip, pelvis, and humerus fractures in men.

Survival and Functional Outcomes after Hip Fracture among Nursing Home Residents

Following the implementation of a long-term care insurance system for the elderly in Korea, many nursing homes have been established and many more patients than ever before have been living at nursing homes. Despite the fact that this is a high-risk group vulnerable to hip fractures, no study has yet been conducted in Korea on hip fracture incidence rates and prognoses among patients residing at nursing homes. We recently studied 46 cases of hip fracture in nursing homes; more specifically, we investigated the most common conditions under which fractures occur, and examined the degree of recovery of ambulatory ability and the mortality within 1 yr. Among those who had survived after 1 yr, the number of non-functional ambulators increased from 8 hips before hip fracture to 19 hips at final post-fracture follow-up. These individuals showed poor recovery of ambulatory ability, and the number who died within one year was 11 (23.9%), a rate not significantly different from that among community-dwelling individuals. It was evident that hip-joint-fracture nursing home residents survived for similar periods of time as did those dwelling in the community, though under much more uncomfortable conditions. The main highlight of this report is that it is the first from Korea on nursing home residents' ambulatory recovery and one-year mortality after hip fracture. The authors believe that, beginning with the present study, the government should collect and evaluate the number of hips fractured at nursing facilities in order to formulate criteria that will help to enable all patients to select safer and better-quality nursing facilities for themselves or their family members.

A systematic review of outcomes following emergency transfer to hospital for residents of aged care facilities

BACKGROUND

residential aged care facility (RACF) resident numbers are increasing. Residents are frequently frail with substantial co-morbidity, functional and cognitive impairment with high susceptibility to acute illness. Despite living in facilities staffed by health professionals, a considerable proportion of residents are transferred to hospital for management of acute deteriorations in health. This model of emergency care may have unintended consequences for patients and the healthcare system. This review describes available evidence about the consequences of transfers from RACF to hospital.

METHODS

a comprehensive search of the peer-reviewed literature using four electronic databases. Inclusion criteria were participants lived in nursing homes, care homes or long-term care, aged at least 65 years, and studies reported outcomes of acute ED transfer or hospital admission. Findings were synthesized and key factors identified.

RESULTS

residents of RACF frequently presented severely unwell with multi-system disease. In-hospital complications included pressure ulcers and delirium, in 19 and 38% of residents, respectively; and up to 80% experienced potentially invasive interventions. Despite specialist emergency care, mortality was high with up to 34% dying in hospital. Furthermore, there was extensive use of healthcare resources with large proportions of residents undergoing emergency ambulance transport (up to 95%), and inpatient admission (up to 81%).

CONCLUSIONS

acute emergency department (ED) transfer is a considerable burden for residents of RACF. From available evidence, it is not clear if benefits of in-hospital emergency care outweigh potential adverse complications of transfer. Future research is needed to better understand patient-centred outcomes of transfer and to explore alternative models of emergency healthcare.

Survival and functional outcomes after hip fracture among nursing home residents

IMPORTANCE

Little is known regarding outcomes after hip fracture among long-term nursing home residents.

OBJECTIVE

To describe patterns and predictors of mortality and functional decline in activities of daily living (ADLs) among nursing home residents after hip fracture.

DESIGN, SETTING, AND PARTICIPANTS

Retrospective cohort study of 60,111 Medicare beneficiaries residing in nursing homes who were hospitalized with hip fractures between July 1, 2005, and June 30, 2009.

MAIN OUTCOMES AND MEASURES

Data sources included Medicare claims and the Nursing Home Minimum Data Set. Main outcomes included death from any cause at 180 days after fracture and a composite outcome of death or new total dependence in locomotion at the latest available assessment within 180 days. Additional analyses described within-residents changes in function in 7 ADLs before and after fracture.

RESULTS

Of 60,111 patients, 21,766 (36.2%) died by 180 days after fracture; among patients not totally dependent in locomotion at baseline, 53.5% died or developed new total dependence within 180 days. Within individual patients, function declined substantially after fracture across all ADL domains assessed. In adjusted analyses, the greatest decreases in survival after fracture occurred with age older than 90 years (vs ≤75 years: hazard ratio [HR], 2.17; 95% CI, 2.09-2.26 [P < .001]), nonoperative fracture management (vs internal fixation: HR for death, 2.08; 95% CI, 2.01-2.15 [P < .001]), and advanced comorbidity (Charlson score of ≥5 vs 0: HR, 1.66; 95% CI, 1.58-1.73 [P < .001]). The combined risk of death or new total dependence in locomotion within 180 days was greatest among patients with very severe cognitive impairment (vs intact cognition: relative risk [RR], 1.66; 95% CI, 1.56-1.77 [P < .001]), patients receiving nonoperative management (vs internal fixation: RR, 1.48; 95% CI, 1.45-1.51 [P < .001]), and patients older than 90 years (vs ≤75 years: RR, 1.42; 95% CI, 1.37-1.46 [P < .001]).

CONCLUSIONS AND RELEVANCE

Survival and functional outcomes are poor after hip fracture among nursing home residents, particularly for patients receiving nonoperative management, the oldest old, and patients with multiple comorbidities and advanced cognitive impairment. Care planning should incorporate appropriate prognostic information related to outcomes in this population.

Gender-specific hip fracture risk in community-dwelling and institutionalized seniors age 65 years and older

In this study of acute hip fracture patients, we show that hip fracture rates differ by gender between community-dwelling seniors and seniors residing in nursing homes. While women have a significantly higher rate of hip fracture among the community-dwelling seniors, men have a significantly higher rate among nursing home residents.

INTRODUCTION

Differences in gender-specific hip fracture risk between community-dwelling and institutionalized seniors have not been well established, and seasonality of hip fracture risk has been controversial.

METHODS

We analyzed detailed data from 1,084 hip fracture patients age 65 years and older admitted to one large hospital center in Zurich, Switzerland. In a sensitivity analysis, we extend to de-personalized data from 1,265 hip fracture patients from the other two large hospital centers in Zurich within the same time frame (total n = 2,349). The denominators were person-times accumulated by the Zurich population in the corresponding age/gender/type of dwelling stratum in each calendar season for the period of the study.

RESULTS

In the primary analysis of 1,084 hip fracture patients (mean age 85.1 years; 78% women): Among community-dwelling seniors, the risk of hip fracture was twofold higher among women compared with men (RR = 2.16; 95% CI, 1.74-2.69) independent of age, season, number of comorbidities, and cognitive function; among institutionalized seniors, the risk of hip fracture was 26% lower among women compared with men (RR = 0.77; 95% CI: 0.63-0.95) adjusting for the same confounders. In the sensitivity analysis of 2,349 hip fracture patients (mean age 85.0 years, 76% women), this pattern remained largely unchanged. There is no seasonal swing in hip fracture incidence.

CONCLUSION

We confirm for seniors living in the community that women have a higher risk of hip fracture than men. However, among institutionalized seniors, men are at higher risk for hip fracture.

Vitamin D supplementation in older adults: searching for specific guidelines in nursing homes

BACKGROUND

The prevalence of vitamin D insufficiency is very high in the nursing home (NH) population. Paradoxically, vitamin D insufficiency is rarely treated despite of strong clinical evidence and recommendations for supplementation. This review aims at reporting the current knowledge of vitamin D supplementation in NH and proposing recommendations adapted to the specificities of this institutional setting.

DESIGN

Current literature on vitamin D supplementation for NH residents was narratively presented and discussed by the French Group of Geriatrics and Nutrition.

RESULT

Vitamin D supplementation is a safe and well-tolerated treatment. Most residents in NH have vitamin D insufficiency, and would benefit from vitamin D supplement. However, only few residents are actually treated. Current specific and personalized protocols for vitamin D supplementation may not be practical for use in NH settings (e.g., assessment of serum vitamin D concentrations before and after supplementation). Therefore, our group proposes a model of intervention based on the systematic supplementation of vitamin D (1,000 IU/day) since the patient's admission to the NH and throughout his/her stay without the need of a preliminary evaluation of the baseline levels. Calcium should be prescribed only in case of poor dietary calcium intake.

CONCLUSION

A population-based rather than individual-based approach may probably improve the management of vitamin D insufficiency in the older population living in NH, without increasing the risks of adverse health problems. The clinical relevance and cost effectiveness of this proposal should be assessed under NH real-world conditions to establish its feasibility.

Effects of fall injury type and discharge placement on mortality, hospitalization, falls, and ADL changes among older people in Taiwan

A longitudinal study was conducted to investigate the effects of injury type and discharge placement on mortality, falls, hospital admissions, and changes in activities of daily living (ADLs) over a 12-month period among older fallers. Of 762 community-dwelling people aged 65 years or older who visited an emergency department (ED) of a general hospital in Taiwan due to a fall, 273 sustained a hip fracture, 157 had a vertebral fracture, 47 had a distal forearm fracture, 102 had a traumatic brain injury, and 183 had soft-tissue injuries. Results showed that, compared to patients with a soft-tissue injury, those with TBI had significantly higher risks of dying (rate ratio (RR)=3.59) and hospital admissions (RR=3.23) and better improvement in ADLs (1.93 points) at 6 months post-injury, and those who sustained a hip fracture (4.26 and 4.41 points), a vertebral fracture (3.81 and 3.83 points), or a distal-forearm fracture (2.80 and 2.80 points) had significantly better improvement in ADLs at 6 and 12 months post-injury. Patients discharged to a nursing home had a significantly increased risk of death (RR=2.08) and hospital admission (RR=2.05) than those returning to their usual residence during the first year post-injury. No significant differences in the occurrence of falls during the first post-injury year were found among patients with different injury types or between those with different discharge placements. In conclusion, among the five major fall injury types in older people, TBIs result in the highest risk of death and hospital admissions, while hip and vertebral fractures exhibited the largest improvement during the first year after injury. Additionally, nursing home care may be associated with increased risks of death and hospital admissions than home care. In addition to primary prevention of falls, further research to investigate mechanisms leading to TBIs during a fall is needed to facilitate effective secondary fall-prevention programs for older people.

A comparison of clinical practice guidelines for proximal femoral fracture

Clinical practice guidelines are designed to assist clinical decision-making by summarising evidence and forming recommendations. The number of available guidelines is vast and they vary in relevance and quality. We reviewed guidelines relevant to the management of a patient with a fractured neck of femur and explored similarities and conflicts between recommendations. As guidelines are often produced in response to an area of clinical uncertainty, recommendations differ. This can result in a situation where the management of a particular clinical problem will depend upon which guideline is followed. We explore the reasons for such differences.

Prevalence of vertebral fracture in oldest old nursing home residents

We evaluated vertebral fracture prevalence using DXA-based vertebral fracture assessment and its influence on the Fracture Risk Assessment (FRAX) tool-determined 10-year fracture probability in a cohort of oldest old nursing home residents. More than one third of the subjects had prevalent vertebral fracture and 50% osteoporosis. Probably in relation with the prevailing influence of age and medical history of fracture, adding these information into FRAX did not markedly modify fracture probability.

INTRODUCTION

Oldest old nursing home residents are at very high risk of fracture. The prevalence of vertebral fracture in this specific population and its influence on fracture probability using the FRAX tool are not known.

METHODS

Using a mobile DXA osteodensitometer, we studied the prevalence of vertebral fracture, as assessed by vertebral fracture assessment program, of osteoporosis and of sarcopenia in 151 nursing home residents. Ten-year fracture probability was calculated using appropriately calibrated FRAX tool.

RESULTS

Vertebral fractures were detected in 36% of oldest old nursing home residents (mean age, 85.9 ± 0.6 years). The prevalence of osteoporosis and sarcopenia was 52% and 22%, respectively. Ten-year fracture probability as assessed by FRAX tool was 27% and 15% for major fracture and hip fracture, respectively. Adding BMD or VFA values did not significantly modify it.

CONCLUSION

In oldest old nursing home residents, osteoporosis and vertebral fracture were frequently detected. Ten-year fracture probability appeared to be mainly determined by age and clinical risk factors obtained by medical history, rather than by BMD or vertebral fracture.

Femoral fracture rates in people with and without disability

OBJECTIVE

to estimate femoral fracture rates in community-dwelling older people without care need (CCN(-)), in community-dwelling older people with care need (CCN(+)) and in residents of nursing homes (RNH) and to determine their contribution to the overall burden of femoral fractures.

METHODS

routine data of more than 1.2 million German people aged 65 years and more were used to calculate sex- and age-specific femoral fracture rates in the three groups CCN(-), CCN(+) and RNH. Those people receiving benefits of the long-term care insurance were defined as having care need. The percentile contribution of the three subpopulations to the overall burden of femoral fractures was determined.

RESULTS

during 5,319,438 person-years, 44,000 femoral fractures were recorded. In each of the three subpopulations female and male fracture rates increased with increasing age. Femoral fracture rates of the total subpopulations were 6.13, 34.53 and 43.05 femoral fractures/1,000 person-years in CCN(-), CCN(+) and RNH in women and 2.66, 20.34 and 31.09 in men, respectively. The contribution of people with care need to the overall burden of femoral fractures in older people was about 50%.

CONCLUSION

the incidence of femoral fractures was considerably higher in people with care need than in people without care need. This should be considered when planning medical care or targeting preventive measures.

Epidemiology and outcome of fracture of the hip in women aged 65 years and under: a cohort study

We examined prospectively collected data from 6782 consecutive hip fractures and identified 327 fractures in 315 women aged ≤65 years. We report on their demographic characteristics, treatment and outcome and compare them with a cohort of 4810 hip fractures in 4542 women aged > 65 years. The first significant increase in age-related incidence of hip fracture was at 45, rather than 50, which is when screening by the osteoporosis service starts in most health areas. Hip fractures in younger women are sustained by a population at risk as a result of underlying disease. Mortality of younger women with hip fracture was 46 times the background mortality of the female population. Smoking had a strong influence on the relative risk of 'early' (≤ 65 years of age) fracture. Lag screw fixation was the most common method of operative treatment. General complication rates were low, as were re-operation rates for cemented prostheses. Kaplan-Meier implant survivorship of displaced intracapsular fractures treated by reduction and lag screw fixation was 71% (95% confidence interval 56 to 81) at five years. The best form of treatment remains controversial.

Socioeconomic and living conditions are determinants of hip fracture incidence and age occurrence among community-dwelling elderly

In this prospective, 10-year study in community-dwelling elderly aged 50 years and over, hip fracture incidence and accordingly age at hip fracture were inversely associated with the area-level income, independently of the geographical area. Age at hip fracture also depended of marital status but in a gender-specific way.

PURPOSE

The purpose of this study is to investigate the impact of socioeconomic and living conditions on hip fracture incidence and age occurrence among community-dwelling elderly.

METHOD

Between January 1991 and December 2000, 2,454 hip fractures were recorded in community-dwelling adults aged 50 years and over in the Geneva University Hospital, State of Geneva, Switzerland. Median annual household income by postal code of residence (referred to as area-level income) based on the 1990 Census was used as a measure of socioeconomic condition and was stratified into tertiles (< 53,170; 53,170-58,678; and ≥ 58,678 CHF). Hip fracture incidence and age occurrence were calculated according to area-level income categories and adjusted for confounding factors among community-dwelling elderly.

RESULTS

Independently of the geographical area (urban versus rural), community-dwelling persons residing in areas with the medium income category presented a lower hip fracture incidence [OR 0.91 (0.82-0.99), p = 0.049] compared to those from the lowest income category. Those in the highest income category had a hip fracture at a significant older age [+1.58 (0.55-2.61) year, p = 0.003] as compared to those in the lowest income category. Age at hip fracture also depended on marital status but in a gender-specific way, with married women fracturing earlier.

CONCLUSIONS

These results indicate that incidence and age occurrence of hip fracture are influenced by area-level income and living conditions among community-dwelling elderly. Prevention programs may be encouraged in priority in communities with low income.

Management of osteoporosis in patients hospitalized for hip fractures

Hip fracture is associated with high morbidity, mortality, and economic burden worldwide. It is also a major risk factor for a subsequent fracture. A literature search on the management of osteoporosis in patients with hip fracture was performed on the Medline database. Only one clinical drug trial was conducted in patients with a recent hip fracture. Further studies that specifically address post-fracture management of hip fracture are needed. The efficacy of anti-osteoporosis medication in older individuals and those at high risk of fall is reviewed in this paper. Adequate nutrition is vital for bone health and to prevent falls, especially in malnourished patients. Protein, calcium, and vitamin D supplementation is associated with increased hip BMD and a reduction in falls. Fall prevention, exercise, and balance training incorporated in a comprehensive rehabilitation program are essential to improve functional disability and survival. Exclusion of secondary causes of osteoporosis and treatment of coexistent medical conditions are also vital. Such a multidisciplinary team approach to the management of hip fracture patients is associated with a better clinical outcome. Although hip fracture is the most serious of all fractures, osteoporosis management should be prioritized to prevent deterioration of health and occurrence of further fracture.

What are the beliefs, attitudes and practices of front-line staff in long-term care (LTC) facilities related to osteoporosis awareness, management and fracture prevention?

BACKGROUND

Compared to the general elderly population, those institutionalized in LTC facilities have the highest prevalence of osteoporosis and subsequently have higher incidences of vertebral and hip fractures. The goal of this study is to determine how well nurses at LTC facilities are educated to properly administer bisphosphonates. A secondary question assessed was the nurse's and PSW's attitudes and beliefs regarding the role and benefits of vitamin D for LTC patients.

METHODS

Eight LTC facilities in Hamilton were surveyed, and all nurses were offered a survey. A total 57 registered nurses were surveyed. A 21 item questionnaire was developed to assess existing management practices and specific osteoporosis knowledge areas.

RESULTS

The questionnaire assessed the nurse's and personal support worker's (PSWs) education on how to properly administer bisphosphonates by having them select all applicable responses from a list of options. These options included administering the drug before, after or with meals, given with or separate from other medications, given with juice, given with or without water, given with the patient sitting up, or finally given with the patient supine. Only 52% of the nurses and 8.7% of PSWs administered the drug properly, where they selected the options: (given before meals, given with water, given separate from all other medications, and given in a sitting up position). If at least one incorrect option was selected, then it was scored as an inappropriate administration. Bisphosphonates were given before meals by 85% of nurses, given with water by 90%, given separately from other medication by 71%, and was administered in an upright position by 79%. Only 52% of the nurses and 8.7% of PSWs surveyed were administering the drug properly. Regarding the secondary question, of the 57 nurses surveyed, 68% strongly felt their patients should be prescribed vitamin D supplements. Of the 124 PSWs who completed the survey, 44.4% strongly felt their patients should be prescribed vitamin D supplementation.

CONCLUSION

Bisphosphonates are quite effective in increasing the bone mineral density of LTC patients, and may reduce fracture rates, but it is only effective if properly administered. In our study, proper administration of bisphosphonate therapy was less than optimal. In summary, although the education of health providers has improved since the mid-1990's, this area still requires further attention and the subject of future quality assurance research.

Nursing staff attitudes of hip protector use in long-term care, and differences in characteristics between adherent and non-adherent residents: a survey and observational study

BACKGROUND

Hip fractures represent an increasing public health burden with a simple fall to the floor as the most common cause. Because nursing home residents are particularly at risk, nursing homes should implement a broad range of fall prevention strategies. However, not all fall incidents can be avoided and external hip protectors may contribute to prevent hip fractures. A major problem in studying the effectiveness of hip protectors is residents' poor adherence. In nursing homes, adherence is dependent not only on the resident, but also on staff knowledge of and attitudes about hip protectors.

OBJECTIVES

To describe (1) attitudes of day versus night shift caregivers towards the use of a soft hip protector, (2) residents' adherence about the use of such protectors, and (3) differences in characteristics between adherent and non-adherent residents.

DESIGN

Survey and observational study.

SETTING

Nursing home.

PARTICIPANTS/METHODS

: Survey of care staff (n=37) in a nursing home after 8 months of continued application of a soft hip protector policy in residents (n=68). Adherence to wearing the hip protector, measured by weekly unannounced, randomly determined checks during day and night in the 8 months after the start of the study.

RESULTS

Overall, 85% agreed to wear a hip protector. At 8 months, only 29% was still wearing their hip protector; with significant differences between day and night shifts. Although virtually all caregivers (97%) considered a hip protector policy in residential care as feasible, the attitude towards hip protectors was found to be significantly different between day and night caregivers. Pain and discomfort, patient insight in the usefulness of these devices, interference with incontinence materials, and the overall resident mix and care acuity were reported as major barriers.

CONCLUSION

Implementing a hip protector policy for injury prevention in long-term care is not an issue of whether or not to use the devices. Rather, it is a continued clinical nursing decision process about when and when not, by whom and by whom not, why and why not, for how long, and to what clinical benefit--considering both the needs of the individual resident and the feasibility of such a policy in the context of resident mix and nursing staff.

A scoping review of strategies for the prevention of hip fracture in elderly nursing home residents

BACKGROUND

Elderly nursing home residents are at increased risk of hip fracture; however, the efficacy of fracture prevention strategies in this population is unclear.

OBJECTIVE

We performed a scoping review of randomized controlled trials of interventions tested in the long-term care (LTC) setting, examining hip fracture outcomes.

METHODS

We searched for citations in 6 respective electronic searches, supplemented by hand searches. Two reviewers independently reviewed all citations and full-text papers; consensus was achieved on final inclusion. Data was abstracted in duplicate.

FINDINGS

We reviewed 22,349 abstracts or citations and 949 full-text papers. Data from 20 trials were included: 7--vitamin D (n = 12,875 participants), 2--sunlight exposure (n = 522), 1--alendronate (n = 327), 1--fluoride (n = 460), 4--exercise or multimodal interventions (n = 8,165), and 5--hip protectors (n = 2,594). Vitamin D, particularly vitamin D(3) > or = 800 IU orally daily, reduced hip fracture risk. Hip protectors reduced hip fractures in included studies, although a recent large study not meeting inclusion criteria was negative. Fluoride and sunlight exposure did not significantly reduce hip fractures. Falls were reduced in three studies of exercise or multimodal interventions, with one study suggesting reduced hip fractures in a secondary analysis. A staff education and risk assessment strategy did not significantly reduce falls or hip fractures. In a study underpowered for fracture outcomes, alendronate did not significantly reduce hip fractures in LTC.

CONCLUSIONS

The intervention with the strongest evidence for reduction of hip fractures in LTC is Vitamin D supplementation; more research on other interventions is needed.

Patient level pooled analysis of 68 500 patients from seven major vitamin D fracture trials in US and Europe

OBJECTIVES

To identify participants' characteristics that influence the anti-fracture efficacy of vitamin D or vitamin D plus calcium with respect to any fracture, hip fracture, and clinical vertebral fracture and to assess the influence of dosing regimens and co-administration of calcium.

DESIGN

Individual patient data analysis using pooled data from randomised trials.

DATA SOURCES

Seven major randomised trials of vitamin D with calcium or vitamin D alone, yielding a total of 68 517 participants (mean age 69.9 years, range 47-107 years, 14.7% men).

STUDY SELECTION

Studies included were randomised studies with at least one intervention arm in which vitamin D was given, fracture as an outcome, and at least 1000 participants.

DATA SYNTHESIS

Logistic regression analysis was used to identify significant interaction terms, followed by Cox's proportional hazards models incorporating age, sex, fracture history, and hormone therapy and bisphosphonate use.

RESULTS

Trials using vitamin D with calcium showed a reduced overall risk of fracture (hazard ratio 0.92, 95% confidence interval 0.86 to 0.99, P=0.025) and hip fracture (all studies: 0.84, 0.70 to 1.01, P=0.07; studies using 10 microg of vitamin D given with calcium: 0.74, 0.60 to 0.91, P=0.005). For vitamin D alone in daily doses of 10 microg or 20 microg, no significant effects were found. No interaction was found between fracture history and treatment response, nor any interaction with age, sex, or hormone replacement therapy.

CONCLUSION

This individual patient data analysis indicates that vitamin D given alone in doses of 10-20 microg is not effective in preventing fractures. By contrast, calcium and vitamin D given together reduce hip fractures and total fractures, and probably vertebral fractures, irrespective of age, sex, or previous fractures.

Ocorrência de quedas em idosos residentes em instituições de longa permanência em Pelotas, Rio Grande do Sul, Brasil

O objetivo deste estudo foi descrever a ocorrência de quedas e fatores associados em idosos residentes em instituições de longa permanência para idosos em Pelotas, Rio Grande do Sul, Brasil. Foi utilizado um questionário estruturado com perguntas sobre características demográficas, morbidade, uso de psicotrópicos e ocorrência de quedas. Em dezembro de 2006, foram visitadas todas as 21 instituições de longa permanência para idosos registradas na cidade. Dentre elas, 19 consentiram em participar do estudo. Foram identificados 377 idosos, mas 96 não tinham condições de responder o questionário e 38 foram recusas. Dos 243 idosos incluídos no estudo, a maioria era mulheres (72,8%) e tinha, em média, 77,7 (DP = 8,9) anos. Cerca de um terço dos idosos (32,5%) sofreu pelo menos uma queda no último ano. A ocorrência de quedas foi duas vezes maior nas mulheres, nos idosos com reumatismo ou doença da coluna e naqueles que utilizavam medicação psicotrópica. Pretende-se que as informações obtidas possibilitem discussões sobre a saúde dos idosos residentes em instituições de longa permanência.

Disaster-related injuries in the period of recovery: the effect of prolonged displacement on risk of injury in older adults

BACKGROUND

Hurricane Katrina, which struck the Gulf Coast of the United States in August 2005, initially displaced over a million people from their primary place of residence. Displaced older adults subsequently faced challenges, such as new or inferior living conditions, which could increase vulnerability to serious or life-threatening injuries such as hip fracture. The aim of this study was to determine whether Katrina victims who were displaced for a prolonged period of time were more likely to experience injuries than nondisplaced victims.

METHODS

We tracked injury outcomes including fractures, sprains or strains, and lacerations in a cohort of 25,019 older adults (age >or= 65 years) enrolled in a Medicare-Advantage Plan, for 1 year after Katrina. We used medical claims to obtain injury outcomes and analyzed propensity-score adjusted predictors of injury, including displacement status at 12 months.

RESULTS

In our sample, 7,030 (28%) older adults were displaced at 12-month post-Katrina. Displaced victims had 1.53 (95% CI: 1.10-2.13) greater odds of sustaining a hip fracture in the year after the storm and 1.24 (95% CI: 1.07-1.44) greater odds of sustaining other fractures after adjusting for other risk factors. There was no significant association between displacement status at 12 months and sprains or strains or lacerations.

CONCLUSIONS

Prolonged displacement is associated with increased risk of fracture in older adults. Emergency planners should screen temporary housing for injury hazards, and clinicians should regard displaced older adults as a vulnerable population in need of interventions such as risk communication messaging.

Fractures after nursing home admission: incidence and potential consequences

SUMMARY

Fracture rates were examined in residents newly admitted to nursing homes. The risk of a fracture was highest during the first months after admission and declined thereafter. This risk pattern was observed independently of fracture site, gender or degree of care need.

INTRODUCTION AND HYPOTHESIS

Residents of nursing homes are a high-risk group for fractures. The aim of the study was to analyse fracture rates as a function of time from admission to nursing home.

METHODS

Fractures of the upper limb, femur, pelvis and lower leg, time to first and subsequent fractures, age, gender and care needs at admission were measured in 93,424 women and men aged 65 years and over and newly admitted to nursing homes in Bavaria between 2001 and 2006.

RESULTS

Fracture incidence was highest during the first months after admission to nursing homes and declined thereafter. This pattern was observed for all fracture sites, in women and men and in residents with different care needs. For example, fracture rates of the upper limb declined from 30.0 to 13.5/1,000 person-years in the first 9 months after admission and for all fracture sites from 135.3 to 69.4/1,000 person-years in a corresponding time period.

CONCLUSION

Newly admitted residents have the highest fracture risk. The pattern of risk is similar across all fractures, suggesting a generic causal pathway. Implementation of effective fracture prevention efforts should be a priority at the time of admission to nursing homes.

Spatial temporal modeling of hospitalizations for fall-related hip fractures in older people

The study determined the spatial temporal characteristics of fall-related hip fractures in the elderly using routinely collected injury hospitalization and sociodemographic data. There was significant spatial temporal variation in hospitalized hip fracture rates in New South Wales, Australia.

INTRODUCTION

The study determined the spatial temporal characteristics of fall-related hip fractures in the elderly using routinely collected injury hospitalization data.

METHODS

All New South Wales (NSW), Australia residents aged 65+ years who were hospitalized for a fall-related hip fracture between 1 July 1998 and 30 June 2004 were included. Bayesian Poisson regression was used to model rates in local government areas (LGAs), allowing for the incorporation of spatial, temporal, and covariate effects.

RESULTS

Hip fracture rates were significantly decreasing in one LGA, and there were no significant increases in any LGAs. The proportion of the population in residential aged care facilities was significantly associated with the rate of hospitalized hip fractures with a relative risk (RR) of 1.003 (95% credible interval 1.002, 1.004). Socioeconomic status was also related to hospitalized hip fractures with those in the third and fourth quintiles being at decreased risk of hip fracture compared to those in the least disadvantaged (fifth) quintile [RR = 0.837 (0.717, 0.972) and RR = 0.855 (0.743, 0.989) respectively].

CONCLUSIONS

There was significant spatial temporal variation in hospitalized hip fracture rates in NSW, Australia. The use of Bayesian methods was crucial to allow for spatial correlation, covariate effects, and LGA boundary changes.

The effect of including quantitative heel ultrasound in models for estimation of 10-year absolute risk of fracture

The role of quantitative ultrasound (QUS) in clinical practice is debatable. An unanswered question is that whether combining QUS and BMD measurements could improve the prediction of fracture risk. We examined this in a sample of men and women in the European Prospective Investigation into Cancer (EPIC)-Norfolk who had both heel QUS and hip DXA between 1995 and 1997 and were followed for any incident fracture up to 2007. From 1455 participants (703 men) aged 65-76 years at baseline, 79 developed a fracture over 10.3+/-1.4 years of follow-up. Two separate sex-stratified Cox proportional-hazard models were used including clinical risk factors and total hip BMD. Heel broadband ultrasound attenuation (BUA) was also included in the second model. Global measures of model fit, area under ROC curve, and the Hosmer-Lemeshow statistic showed relative superiority of the model including BUA. Using each model, we calculated 10-year absolute risk of fracture for all participants and categorized them in groups of < 5%, 5% to < 15%, and > or = 15%. Comparison of groupings showed a total re-classification of 16.6% of participants after inclusion of BUA with the greatest re-classification (30.7%) among the group with intermediate risk. Adding a QUS measurement to models based on clinical risk factors and BMD improves the predictive power of models and suggests that further attention should be paid to QUS as a clinical tool for fracture risk assessment.

Use of emergency departments by older people from residential care: a population based study

OBJECTIVE

to investigate the differences between emergency department (ED) presentations of older people who do and do not live in residential care facilities (RCFs).

DESIGN

a population-based retrospective cohort study. ED records linked to ambulance and hospital morbidity records.

SETTING

public EDs in Perth, Western Australia.

SUBJECTS

all patients 65 years and older who presented to EDs between 1 January 2003 and 31 December 2006 (n = 97,161).

MEASUREMENTS

patient demographic and clinical characteristics. Logistic regression was used to model the effect of living in RCFs on the likelihood of a particular ED diagnosis, hospital admission and in-hospital death.

RESULTS

the age-sex standardised rate of ED presentation for those living in RCFs was 1.69 times that of community dwellers. Compared to community dwellers, people from RCFs were older (mean age 84.7 years vs. 76.0 years, P < 0.001) and a lower proportion were male (28.7% vs. 46.7%, P < 0.001). Adjusting for age and sex revealed that people from RCFs were more likely to be diagnosed with pneumonia/influenza [odds ratio (OR) 1.94, 95% confidence interval (CI) = 1.72-2.19], urinary tract infections (OR 1.72, 95% CI 1.49-1.98) or hip fractures (OR 1.16, 95% CI 1.03-1.32); less likely to be diagnosed with circulatory system diseases (OR 0.69, 95% CI 0.64-0.75) or neoplasms (OR 0.47, 95% CI 0.31-0.72); more likely to be admitted (OR 1.13, 95% CI 1.06-1.20) and to die in hospital (OR 1.57, 95% CI 1.40-1.75).

CONCLUSION

there are different patterns of ED presentations and hospital admissions of older people who do and do not live in RCFs. The appropriateness of these differences is uncertain.

Cost-effectiveness of preventing hip fractures by hip protectors in elderly institutionalized residents in Germany

OBJECTIVE

To determine the long-term cost-effectiveness of hip protector use in the prevention of hip fractures in elderly institutionalized residents in Germany compared to no prevention.

METHODS

A lifetime Markov decision model was developed using published data on costs and health outcomes. A societal and statutory health insurance perspective was adopted.

RESULTS

From a societal/statutory health insurance perspective, use of hip protectors yields savings of 315 EURO/257 EURO and a gain of 0.13 quality-adjusted life years per person over lifetime.

CONCLUSION

Hip protector use in elderly institutionalized residents in Germany is highly cost-effective.

Reversal of the hip fracture secular trend is related to a decrease in the incidence in institution-dwelling elderly women

In this prospective 10-year study in elderly aged 60 years and over, there was a 1.3% per year reduction in the standardized incidence of hip fracture in women but not in men. This decrease was mainly due to changes in the standardized incidence of hip fracture in institution-dwelling women.

INTRODUCTION

A decrease in age-adjusted hip fracture incidence has been recently demonstrated in some countries. Since a large proportion of hip fractures occur in nursing homes, we analyzed whether this decreasing trend would be more detectable in institution-dwelling elderly compared with community-dwelling elderly.

METHODS

All hip fracture patients aged 60 years and over were identified in a well-defined area. Incidence of hip fracture, age- and sex-adjusted to the 2000 Geneva population, was computed in community- and institution-dwelling elderly.

RESULTS

From 1991 to 2000, 1,624 (41%) hip fractures were recorded in institutionalized-dwelling elderly and 2,327 (59%) in community-dwelling elderly. The standardized fracture incidence decreased by 1.3% per year in women (p = 0.039), but remained unchanged in men (+0.5%; p = 0.686). Among institution-dwelling women, hip fracture incidence fell by 1.9% per year (p = 0.044), whereas it remained stable among community-dwelling women (+0.0%, p = 0.978). In men, no significant change in hip fracture incidence occurred among institution- or community-dwelling elderly.

CONCLUSIONS

The decrease in the standardized hip fracture incidence in institution-dwelling women is responsible for the reversal in secular trend. Future research should include stratification according to the residential status to better identify the causes responsible for the trend in hip fracture incidence.

Hip fractures in institutionalized elderly people: incidence rates and excess mortality

It is assumed that nursing homes are the setting with the highest incidence of hip fractures. This observation is, however, based on very little data. The aim of this study was to analyze hip fracture rates and the associated excess mortality in a large nursing home population. A cohort of >69,000 women and men newly admitted to German nursing homes were used to calculate sex- and age-specific incidence rates of hip fractures. To calculate excess mortality, a retrospective cohort study was conducted. To each patient with a hip fracture (n = 4342), four residents without hip fracture (n = 17,368) were matched by sex, age, and level of care (measure for the need of care). Hazard regression models were applied. During 91,850 person-years, 4342 hip fractures were observed. The crude incidence rates for hip fractures were 50.8/1000 person-years in women and 32.7/1000 person-years in men. The incidence rates increased with increasing age categories and were highest in the first months after admission to the nursing home. Increasing care need reduced the risk of hip fracture. Mortality in patients with a hip fracture was increased (women: hazard rate ratio for the first 3 mo after fracture, 1.72; 95% CI, 1.59-1.86; men: hazard ratio, 2.14; 95% CI, 1.80-2.53), but excess mortality was limited to the first months after injury. Data are presented for hip fracture rates and excess mortality after a hip fracture. Our results have implications on the timing and the allocation of specific measures for hip fracture prevention.

[Acute orthogeriatric care (II). Clinical aspects]

The present article reviews the clinical principles of acute orthogeriatric care. The application of geriatric medicine to patients with hip fracture is explained. The principal stages of geriatric intervention in this process are mentioned, as are the interventions to be carried out by the geriatric team. Subsequently, we discuss the management of several frequent problems in these patients, such as high surgical risk, pain management, anaemia, delirium, malnutrition, and discharge planning. Lastly, the characteristics of several kinds of patients with special characteristics are mentioned, such as those diagnosed with dementia, nursing home residents or the oldest-old. Areas of improvement in the acute phase are also reviewed, such as mortality reduction, functional outcome improvement and the need for more efficient resource use in patients in the acute phase of hip fracture.

Characterisation of patients with postmenopausal osteoporosis in French primary healthcare

BACKGROUND

The public health burden of osteoporosis is high, principally because of increased risk of fractures and associated morbidity, handicap and mortality. Osteoporotic fracture prevention is therefore an important public health goal. General practitioners (GPs) play a key role in the management of osteoporosis, both in ensuring timely diagnosis and in providing treatment. Little information is available on standards of care for postmenopausal women with osteoporosis in general practice.

OBJECTIVES

The primary objective of this study was to describe risk factors and treatment in postmenopausal women with osteoporosis. Secondary objectives were to evaluate treatment compliance and to assess the impact of osteoporosis on quality of life.

METHODS

This observational, cross-sectional, pharmacoepidemiological study was performed in a primary-care setting in France. A random sample of GPs recruited postmenopausal women with a diagnosis of osteoporosis who had been followed by the investigator for at least 2 years. At inclusion, investigators completed a questionnaire providing information on patient age, osteoporosis duration, risk factors and treatment history. The first three patients recruited by each investigator completed a questionnaire providing information on sociodemographic features, osteoporosis treatments and quality of life. Treatment compliance was quantified using the Test d'Evaluation de l'Observance and quality of life evaluated using the 12-item Short Form Health Survey (SF-12).

RESULTS

Overall, 389 physicians included 3,097 patients, of whom 1,053 completed the patient questionnaire. Risk factors for osteoporotic fracture were identified in 2,148 patients (69.4%), most frequently personal or maternal antecedents of osteoporotic fracture and a low body mass index. Of these, 946 (44.0%) presented more than one risk factor. At the time of diagnosis, 629 patients (59.7%) presented fractures, which involved the vertebrae in 51.7% of cases, the wrist in 40.5% and the hip in 5.4%. Older patients were more likely to have fractures at the time of diagnosis and to have multiple fractures. After diagnosis, at least one new fracture occurred in 201 patients (19.2%). Multivariate logistic regression analysis identified age >70 years, diagnosis at least 10 years previously, diagnosis based on the presence of a fracture, biochemical and haematological evaluation at the time of diagnosis, and a change in osteoporosis treatment in the previous 2 years as being significantly associated with incident fracture risk. At inclusion, 1,019 patients (97.4%) were receiving treatment for osteoporosis, most frequently weekly bisphosphonates (71.6% of treatments). Most patients (81.0%) had been treated for at least 1 year. Treatment compliance was high in 61% of patients and low in <5%. Patient variables associated with high compliance were being retired, prescription of bisphosphonates and, among the bisphosphonate users, prescription of weekly formulations. SF-12 quality-of-life scores were low, ranging from 38.6 (energy/vitality) to 65.1 (social functioning) out of a possible maximum score of 100. Baseline variables associated with SF-12 physical component summary scores included age, height loss since menopause, diagnosis following a fracture, fracture incidence since diagnosis, time since diagnosis and treatment with bisphosphonates.

CONCLUSIONS

In this study of postmenopausal osteoporosis in the French primary healthcare setting, many women with osteoporosis were diagnosed following a fracture. Although most were treated with bone-consolidating drugs, compliance was suboptimal in a significant minority. Osteoporotic fracture was associated with reduced quality of life.

Home injuries mortality: sensitivity and specificity analysis of different data sources and operative definitions

The aim of this longitudinal study was to test different operational definitions of home accident mortality.

METHODS

The sources of data were the Emergency Information System, hospital discharge reports and the mortality registry of the Lazio Region, 2000-2001. We selected all emergency room visits for unintentional traumas that occurred at home. A 9-month follow-up was performed to calculate mortality rates. A sensitivity analysis of in-hospital mortality, deaths within 30 days and deaths from home accident E-codes was performed. A gold standard definition of home accident-related deaths was proposed.

RESULTS

We observed 598 home accident-related fatalities (29.1% of all the deaths found in the follow-up study). In-hospital mortality, deaths within 30 days and deaths for home accident E-codes had sensitivity values of 63.4%, 63.4% and 59.4%, respectively; positive predictive values were 78.1%, 67.1% and 100%, respectively.

CONCLUSIONS

The best operational definition of home injury was based on in-hospital mortality, while mortality based on E-codes reported on death certificates was lacking. In order to measure the real burden of home injuries, hospital and mortality data must be integrated.
