Predictors of Long-Term Mortality in Older People With Hip Fracture

Non-linear relationship between preoperative albumin-globulin ratio and postoperative pneumonia in patients with hip fracture

BACKGROUND AND OBJECTIVE

Postoperative pneumonia (POP) is the leading cause of death among patients with hip fractures. Simple and cost-effective markers can be used to assess the risk of these patients. This study aims to investigate the association between POP and preoperative albumin-globulin ratio (AGR) in patients with hip fractures.

METHODS

A retrospective analysis was conducted on data from 1417 hip fracture patients admitted to the Department of Orthopaedics at the hospital. Generalized additive and logistic regression models were used to determine both linear and non-linear associations between preoperative AGR and POP. A two-piece regression model was employed to determine the threshold effect.

RESULTS

The study included 1417 participants, with a mean age of 77.57 (8.53) years and 26.96% (382/1417) male patients. The prevalence of POP was 6.21%. Following full covariate adjustment, each unit increase in AGR was associated with a 79% reduction in the incidence of POP (OR, 0.23; 95% CI: 0.08-0.63; P = 0.0046). The inflection point was found to be 1.33 using a two-piecewise regression model. For each unit increase in AGR on the left side of the inflection point, the incidence of POP decreased by 93% (OR, 0.07; 95%CI: 0.02-0.34; P = 0.0010). However, there was no statistically significant correlation on the right side of the inflection point (OR, 0.84; 95% CI: 0.17-4.10; P = 0.8287).

CONCLUSION

There exists a non-linear association between preoperative AGR and the incidence of POP in elderly hip fracture patients. When AGR is less than 1.33, the incidence of POP is negatively correlated with AGR. However, there is no correlation when AGR is greater than 1.33.

Early Postoperative Weight-Bearing Ability after Total Hip Arthroplasty versus Bipolar Hemiarthroplasty in Elderly Patients with Femoral Neck Fracture

Background: Femoral neck fractures are among the most common types of fractures and particularly affect elderly patients. Two of the most common treatment strategies are total hip arthroplasty (THA) and bipolar hemiarthroplasty (BA). However, the role of the different treatment strategies in the postoperative weight-bearing ability in the early postoperative phase is still not entirely clear. Methods: Patients who underwent either THA or BA were consecutively included in our prospective cohort study. Gait analysis was performed during the early postoperative period. The gait analysis consisted of a walking distance of 40 m coupled with the turning movement in between. During the gait analysis, the duration of the measurement, the maximum peak force and the average peak force were recorded. Results: A total of 39 patients were included, 25 of whom underwent BA and 14 of whom underwent THA. The maximum peak force during the gait analysis was, on average, 80.6% ± 19.5 of the body weight in the BA group and 78.9% ± 21.6 in the THA group. The additionally determined average peak force during the entire gait analysis was 66.8% ± 15.8 of the body weight in the BA group and 60.5% ± 15.6 in the THA group. Conclusions: Patients with femoral neck fractures undergoing THA and BA can achieve sufficient weight bearing on the operated leg in the early postoperative period. In our study, BA did not allow for a significantly higher average and maximum loading capacity compared with THA.

Respiratory Complications Are the Main Predictors of 1-Year Mortality in Patients with Hip Fractures: The Results from the Alzira Retrospective Cohort Study

Introduction: Hip fractures pose a significant challenge for older individuals given their high incidence and one-year mortality rate. The objective of this study was to identify the primary predictors of one-year mortality in older adults hospitalized for hip fractures. Methods: We conducted a retrospective cohort study involving adults aged 70 years or older who were admitted to the hospital for fragility hip fractures between 1 January 2014 and 31 December 2021. A total of 3229 patients were recruited, with 846 (26.2%) experiencing one-year mortality. Results: Respiratory complications (HR 2.42, 95%CI 1.42-4.14; p = 0.001) were the most significant predictors of one-year mortality, followed by hospital readmission (HR 1.96, 95%CI 1.66-2.32; p < 0.001), the male sex (HR 1.88, 95%CI 1.46-2.32; p < 0.001), cardiac complications (HR 1.88, 95%CI 1.46-2.32; p < 0.001), and a diagnosis of dementia at admission (HR 1.37, 95%CI 1.13-1.66; p = 0.001). The Charlson Index and the American Society of Anesthesiologists physical status classification system also significantly increased the mortality risk. Conversely, higher hemoglobin levels at admission and elevated albumin at discharge significantly reduced the mortality risk. Conclusions: The one-year mortality rate is substantial in older adults with hip fractures who are admitted to an orthogeriatric unit. The appropriate management of anemia, nutritional disorders, and comorbidity at admission and during the follow-up could potentially mitigate long-term mortality after hip fractures.

Systematic review and meta-analysis of preoperative predictors for early mortality following hip fracture surgery

Hip fractures are a global health problem with a high postoperative mortality rate. Preoperative predictors for early mortality could be used to optimise and personalise healthcare strategies. This study aimed to identify predictors for early mortality following hip fracture surgery. Cohort studies examining independent preoperative predictors for mortality following hip fracture surgery were identified through a systematic search on Scopus and PubMed. Predictors for 30-day mortality were the primary outcome, and predictors for mortality within 1 year were secondary outcomes. Primary outcomes were analysed with random-effects meta-analyses. Confidence in the cumulative evidence was assessed using the GRADE criteria. Secondary outcomes were synthesised narratively. Thirty-three cohort studies involving 462,699 patients were meta-analysed. Five high-quality evidence predictors for 30-day mortality were identified: age per year (OR: 1.06, 95% CI: 1.04-1.07), ASA score ≥ 3 (OR: 2.69, 95% CI: 2.12-3.42), male gender (OR: 2.00, 95% CI: 1.85-2.18), institutional residence (OR: 1.81, 95% CI: 1.31-2.49), and metastatic cancer (OR: 2.83, 95% CI: 2.58-3.10). Additionally, six moderate-quality evidence predictors were identified: chronic renal failure, dementia, diabetes, low haemoglobin, heart failures, and a history of any malignancy. Weak evidence was found for non-metastatic cancer. This review found relevant preoperative predictors which could be used to identify patients who are at high risk of 30-day mortality following hip fracture surgery. For some predictors, the prognostic value could be increased by further subcategorising the conditions by severity.

Risk prediction models of mortality after hip fracture surgery in older individuals: a systematic review

OBJECTIVE

This study aimed to critically assess existing risk prediction models for postoperative mortality in older individuals with hip fractures, with the objective of offering substantive insights for their clinical application.

DESIGN

A comprehensive search was conducted across prominent databases, including PubMed, Embase, Cochrane Library, SinoMed, CNKI, VIP, and Wanfang, spanning original articles in both Chinese and English up until 1 December 2023. Two researchers independently extracted pertinent research characteristics, such as predictors, model performance metrics, and modeling methodologies. Additionally, the bias risk and applicability of the incorporated risk prediction models were systematically evaluated using the Prediction Model Risk of Bias Assessment Tool (PROBAST).

RESULTS

Within the purview of this investigation, a total of 21 studies were identified, constituting 21 original risk prediction models. The discriminatory capacity of the included risk prediction models, as denoted by the minimum and maximum areas under the subject operating characteristic curve, ranged from 0.710 to 0.964. Noteworthy predictors, recurrent across various models, included age, sex, comorbidities, and nutritional status. However, among the models assessed through the PROBAST framework, only one was deemed to exhibit a low risk of bias. Beyond this assessment, the principal limitations observed in risk prediction models pertain to deficiencies in data analysis, encompassing insufficient sample size and suboptimal handling of missing data.

CONCLUSION

Subsequent research endeavors should adopt more stringent experimental designs and employ advanced statistical methodologies in the construction of risk prediction models. Moreover, large-scale external validation studies are warranted to rigorously assess the generalizability and clinical utility of existing models, thereby enhancing their relevance as valuable clinical references.

Utilizing a nomogram to predict the one-year postoperative mortality risk for geriatric patients with a hip fracture

Despite the abundance of research on the risk factors for mortality following hip fracture surgery, there has been a dearth of studies on prediction models in this population. The objective of this research was to explore the influencing factors and construct a clinical nomogram to predict one-year postoperative mortality in patients with hip fracture surgeries. Using the Ditmanson Research Database (DRD), we included 2333 subjects, aged ≥ 50 years who underwent hip fracture surgery between October, 2008 and August, 2021. The endpoint was all-cause mortality. A least absolute shrinkage and selection operator (LASSO) derived Cox regression was performed to select the independent predictors of one-year postoperative mortality. A nomogram was built for predicting one-year postoperative mortality. The prognostic performance of nomogram was evaluated. On the basis of tertiary points in a nomogram, the patients were divided into low, middle and high risk groups, and compared by the Kaplan-Meier analysis. Within 1 year after hip fracture surgery, 274 patients (11.74%) died. Variables retained in the final model comprised age, sex, length of stay, RBC transfusions, hemoglobin, platelet, and eGFR. The AUC for one-year mortality predictions were 0.717 (95% CI = 0.685-0.749). The Kaplan-Meier curves were significantly different among the three risk groups (p < 0.001). The nomogram showed good calibration. In summary, we explored the one-year postoperative mortality risk in geriatric patients with a hip fracture and developed a prediction model that could help clinicians identify patients at high risk of postoperative mortality.

Risk factors for mortality after hip fracture surgery in Japan using the National Database of Health Insurance Claims and Specific Health Checkups of Japan

We investigated the risk factors for mortality of hip fracture in the elderly using the National Database of Health Insurance Claims in Japan, and survival was significantly related to sex, age, fracture type, surgical procedure, delayed operative date, comorbidities, blood transfusions, and pulmonary embolism.

PURPOSE

Hip fracture is the most common fracture in the elderly and is known to have a high mortality rate. In Japan, to the best of our knowledge, no studies have reported on mortality risk factors for hip fracture using nationwide registry databases. This study aimed to determine the number of occurrences of hip fracture and factors that increase mortality using the National Database of Health Insurance Claims and Specific Health Checkups of Japan.

METHODS

This study included extracted data from patients who were hospitalized and underwent surgical treatment for hip fracture between 2013 and 2021, using a nationwide health insurance claims database in Japan. Patient characteristics, such as sex, age, fracture type, surgical procedure, delayed operative date, comorbidities, blood transfusions, and pulmonary embolism, were tabulated to obtain 1-year and in-hospital mortality rates.

RESULTS

Both 1-year and in-patient survival were significantly lower in men, older patients, patients who underwent surgery after 3 days of admission, and patients with trochanteric and subtrochanteric fractures, internal fixation, more preoperative comorbidities, blood transfusions, and pulmonary embolism.

CONCLUSIONS

Survival was significantly related to sex, age, fracture type, surgical procedure, delayed operative date, comorbidities, blood transfusions, and pulmonary embolism. As the number of male patients with hip fracture will increase with the aging of society, medical staff must provide sufficient information before surgery to avoid postoperative mortality.

Mortality following hip fracture: Trends and geographical variations over the last SIXTY years

INTRODUCTION

The management of hip fractures has advanced on all aspects from prevention pre-operatively, specialised hip fracture units, early operative intervention and rehabilitation. This is in line with the appropriate recognition over the past years of an important presentation with significant mortality and socioeconomic consequences of ever increasing incidence in an aging population. It is therefore imperative to continue to gather data on the incidence and trends of hip fractures to guide future management planning of this important presentation.

METHODS

A review of all articles published on the outcome after hip fracture over a twenty year period (1999-2018) was undertaken to determine any changes that had occurred in the demographics and mortality over this period. This article complements and expands upon the findings of a previous article by the authors assessing a four decade period (1959 - 1998) and attempts to present trends and geographical variations over sixty years.

RESULTS

The mean age of patients sustaining hip fractures continues to be steadily increasing at approximately just over 1 year of age for every 5-year time period. The mean age of patients sustaining hip fractures increased from 73 years (1960s) to 81 years (2000s) to 82 years (2010s). Over the six decade period one-year mortality has reduced from an overall mean of 27% (1960s) to 20% (2010s). The proportion of female hip fractures has decreased from 84% (1960s) to 70% (2010s). There is a decreasing trend in the proportion of intracapsular fractures from 54% (1970s) to 49% (2000s) and 48% (2010s).

CONCLUSION

Our study indicates that significant progress has been made with preventative planning, medical management, specialised orthogeriatric units and surgical urgency all playing a role in the improvements in mean age of hip fracture incidence and reduction in mortality rates. While geographical variations do still exist there has been an increase in the study of hip fractures globally with results now being published from more widespread institutions indicating appropriate increased attention and commitment to an ever-increasing presentation.

Impact of Dementia on Long-Term Hip Fracture Surgery Outcomes: An Electronic Health Record Analysis

OBJECTIVE

Older adults with dementia are at higher risk for sustaining hip fracture and their long-term health outcomes after surgery are usually worse than those without dementia. Widespread adoption of electronic health records (EHRs) may allow hospitals to better monitor long-term health outcomes in patients with dementia after hospitalization. This study aimed to (1) estimate how dementia influences discharge location, mortality, and readmission 180 days and 1 year after hip fracture surgery in older adults, and (2) demonstrate the feasibility of using selection-bias reduced EHR data for research and long-term health outcomes monitoring.

DESIGN

Retrospective observational cohort study using EHRs.

SETTING AND PARTICIPANTS

A cohort of 1171 patients over age 65 years who had an initial hip fracture surgery between October 2015 and December 2018 was extracted from EHRs of one health system; 376 of these patients had dementia.

METHODS

Logistic regression was applied to estimate influences of dementia on discharge disposition and Cox proportional hazards model for mortality. The Fine and Gray regression model was used to analyze readmission, accounting for the competing risk of death. To reduce selection bias in EHRs, inverse probability of treatment weighting using propensity scores was implemented before modeling.

RESULTS

Dementia had significant impacts on all outcomes: being discharged to facilities [odds ratio (OR) = 2.11, 95% confidence interval (CI) 1.19-3.74], 180-day mortality [hazard ratio (HR) = 1.69, 95% CI 1.20-2.38], 1-year mortality (HR = 1.78, 95% CI 1.33-2.38), 180-day readmission (HR = 1.62, 95% CI 1.39-1.89), and 1 year readmission (HR = 1.39, 95% CI 1.21-1.58).

CONCLUSIONS AND IMPLICATIONS

Dementia was a significant risk factor for worse long-term outcomes. The inverse probability of treatment weighting approach can be used to reduce selection bias in EHR data for research and monitoring long-term health outcomes in the target population. Such monitoring could foster collaborations with post-acute and long-term health care services to improve recovery outcomes in patients with dementia after hip fracture surgery.

Influencing factors of weak grip strength and fall: a study based on the China Health and Retirement Longitudinal Study (CHARLS)

BACKGROUND

Fall is a major cause of mortality and cause a significant burden on the healthcare system and economic system. Weak grip strength signifies impaired function. Older people with weak grip strength are at a higher risk of death. China has the largest ageing population in the world today. This study aims to analyze the factors contributing to weak grip strength and fall among Chinese.

METHODS

This study analyzed data from the 2011 baseline and 2015 follow-up survey of the China Health and Retirement Longitudinal Study (CHARLS). To identify the risk factors of fall and weak grip strength, we used a stepwise multivariable logistic regression model and a least absolute shrinkage and selection operator (LASSO) regression model.

RESULTS

In the LASSO regression model, all the risk factors were not shrunken. In the stepwise logistic regression model, adjusted for gender, age, grip strength, depression, and chronic disease, we found that female (aOR = 1.376, 95% CI = 1.243-1.523; P < 0.001), history of ischemic stroke (aOR = 1.786, 95% CI = 1.263-2.524; P = 0.001), depression (aOR = 1.559, 95% CI = 1.396-1.742; P < 0.001), weak grip strength (aOR = 1.285, 95% CI = 1.105-1.494; P = 0.001), older age (aOR = 1.227, 95% CI = 1.163-1.294; P < 0.001), rheumatoid arthritis (aOR = 1.410, 95% CI = 1.270-1.560; P < 0.001), history of kidney disease (aOR = 1.383, 95% CI = 1.136-1.682; P = 0.001) were factors associated with fall significantly. After further adjusting, we found the risk factors of weak grip strength included symptomatic knee osteoarthritis (aOR = 1.755, 95% CI 1.158-2.661; P = 0.008), living in rural area (aOR = 2.056, 95% CI 1.290-3.277; P = 0.002), depression (aOR = 1.523, 95% CI 1.116-2.078; P = 0.008), older age (aOR = 2.116, 95% CI 1.801-2.486; P < 0.001).

CONCLUSION

From the study, we found that older age and depression were risk factors of weak grip strength and fall. Weak grip strength was a risk factor of fall. Female, ischemic stroke, kidney disease, rheumatoid arthritis were risk factors of fall; living in rural area and symptomatic knee osteoarthritis were risk factors of weak grip strength.

The effect of postoperative weight-bearing status on mortality rate following proximal femoral fractures surgery

INTRODUCTION

Proximal femur fractures are associated with an increased mortality rate in the elderly. Early weight-bearing presents as a modifiable factor that may reduce negative postoperative outcomes and complications. As such, we aimed to compare non-weight-bearing, partial-weight-bearing and full weight-bearing cohorts, in terms of risk factors and postoperative outcomes and complications.

METHODS

We retrospectively reviewed our database to identify the three cohorts based on the postoperative weight-bearing status the day of surgery from 2003 to 20014. We collected data on numerous risk factors, including age, cerebrovascular accident (CVA), pulmonary embolism (PE), surgical fixation method and diagnosis type. We also collected data on postoperative outcomes, including the number of days of hospitalization, pain levels, and mortality rate. We performed a univariate and multivariate analysis; P < 0.05 was the significant threshold.

RESULTS

There were 186 patients in the non-weight-bearing group, 127 patients in the partial-weight-bearing group and 1791 patients in the full weight-bearing group. We found a significant difference in the type of diagnosis between cohorts (P < 0.001 in univariate, P < 0.001 in multivariate), but not in fixation type (P < 0.001 in univariate, but P = 0.76 in multivariate). The full weight-bearing group was diagnosed most with pertrochanteric fracture, 48.0%, and used Richard's nailing predominantly. Finally, we found that age was not a significant determinant of mortality rate but only weight-bearing cohort (P = 0.13 vs. P < 0.001, respectively).

CONCLUSION

We recommend early weight-bearing, which may act to decrease the mortality rate compared to non-weight-bearing and partial weight-bearing. In addition, appropriate expectations and standardizations should be set since age and type of diagnosis act as significant predictors of weight-bearing status.

Is Cold Apparent Temperature Associated With the Hospitalizations for Osteoporotic Fractures in the Central Areas of Wuhan? A Time-Series Study

Osteoporosis is alarming problem due to aggravation of global aging, especially in China. Osteoporotic fracture (OF) is one of the most severe consequents of osteoporosis. Many previous studies found that environmental factors had adverse effects on human health. Cold temperature was associated with OF and bone metabolism in prior observational and experimental researches. However, few studies had been conducted on the acute effect of low temperature and OF. Data on daily meteorological factors and hospitalizations for OF were collected from Wuhan, China, between January 1, 2017 to December 24, 2019. Apparent temperature (AT), comprehensively considered a variety of environmental factors, was calculated by ambient temperature, relative humidity and wind speed. A generalized linear regression model combined with distributed lag non-linear regression model (DLNM) with quasi-Poisson link was used to explore the association between AT and the number of hospitalizations for OF. Subgroup analyses stratified by gender, age and the history of fracture were applied for detecting susceptible people. The exposure-response curve of AT and OF were generally U-shaped with lowest point at 25.8°C. The significant relationship of AT-OF existed only in cold effect (-2.0 vs. 25.8°C) while not in warm effect (37.0 vs. 25.8°C). Statistically significant risks of OF for cold effects were only found in females [RR = 1.12 (95%CI: 1.02, 1.24) at lag 2 day], aged <75 years old [RR = 1.18 (95%CI: 1.04, 1.33) and 1.17 (95%CI: 1.04, 1.33) at lag 2 and 3 days, respectively] and people with history of fracture [RR = 1.39 (95%CI: 1.02, 1.90) and 1.27 (95%CI: 1.05, 1.53) at lag 1 and 2 days, respectively]. The significant associations of AT on OF were only found in cold effect. The females, people aged <75 years and people with history of fracture possibly appeared to be more vulnerable. Public health departments should pay attention to the negative effect of cold AT and take measures in time.

Lower 1-Year Postoperative Mortality After Acetabular Versus Proximal Femoral Fractures in Elderly Patients

BACKGROUND

Geriatric acetabular fractures are becoming more common due to demographic changes. Compared with proximal femoral fractures, surgical treatment is more complex and often does not allow full-weight-bearing. The aims of this study were to compare operatively treated acetabular and proximal femoral fractures with regard to (1) cumulative 1-year mortality, (2) perioperative complications, and (3) predictive factors associated with a higher 1-year mortality.

METHODS

This institutional review board-approved comparative study included 486 consecutive surgically treated elderly patients (136 acetabular and 350 proximal femoral fractures). After matching, 2 comparable groups of 129 acetabular and 129 proximal femoral fractures were analyzed. Cumulative 1-year mortality was evaluated through Kaplan-Meier survivorship analysis, and perioperative complications were documented and graded. After confirming that the proportionality assumption was met, Cox proportional hazard modeling was conducted to identify factors associated with increased 1-year mortality.

RESULTS

The acetabular fracture group had a significantly lower cumulative 1-year mortality before matching (18% compared with 33% for proximal femoral fractures, log-rank p = 0.001) and after matching (18% compared with 36%, log-rank p = 0.005). Nevertheless, it had a significantly higher overall perioperative complication rate (68% compared with 48%, p < 0.001). In our multivariable Cox regression analysis, older age, perioperative blood loss of >1 L, and wheelchair mobilization were associated with lower survival rates after acetabular fracture surgery. Older age and a higher 5-item modified frailty index were associated with a higher 1-year mortality rate after proximal femoral fractures, whereas postoperative full weight-bearing was protective.

CONCLUSIONS

Despite the complexity of operative treatment and a higher complication rate after acetabular fractures in the elderly, the 1-year mortality rate is lower than that after operative treatment of proximal femoral fractures, even after adjustment for comorbidities.

Sex Differences in Recovery Across Multiple Domains Among Older Adults With Hip Fracture

BACKGROUND

Hip fractures are a public health problem among older adults, but most research on recovery after hip fracture has been limited to females. With growing numbers of hip fractures among males, it is important to determine how recovery outcomes may differ between the sexes.

METHODS

168 males and 171 females were enrolled within 15 days of hospitalization with follow-up visits at 2, 6, and 12 months postadmission to assess changes in disability, physical performance, cognition, depressive symptoms, body composition, and strength, and all-cause mortality. Generalized estimating equations examined whether males and females followed identical outcome recovery assessed by the change in each outcome.

RESULTS

The mean age at fracture was similar for males (80.4) and females (81.4), and males had more comorbidities (2.5 vs 1.6) than females. Males were significantly more likely to die over 12 months (hazard ratio 2.89, 95% confidence interval: 1.56-5.34). Changes in outcomes were significantly different between males and females for disability, gait speed, and depressive symptoms (p < .05). Both sexes improved from baseline to 6 months for these measures, but only males continued to improve between 6 and 12 months. There were baseline differences for most body composition measures and strength; however, there were no significant differences in change by sex.

CONCLUSIONS

Findings confirm that males have higher mortality but suggest that male survivors have continued functional recovery over the 12 months compared to females. Research is needed to determine the underlying causes of these sex differences for developing future prognostic information and rehabilitative interventions.

Elderly patients with concurrent hip fracture and lower respiratory tract infection: the pathogens and prognosis over different bedridden periods

BACKGROUND

Elderly patients who experience hip fractures often become bedridden and are at risk of developing lower respiratory tract infections. The current study was to investigate the etiology and bacterial drug resistance patterns of elderly patients with hip fractures and lower respiratory tract infections on prolonged bedridden time and to determine their prognosis.

METHODS

Patients diagnosed with hip fractures admitted from May 2015 to April 2017 were included. The basic characteristics including the patients' gender, age, fracture type, operation mode, bedridden duration, length of hospital stay, prognosis, past medical history, routine bloodwork, C-reactive protein (CRP), procalcitonin (PCT), blood biochemistry, blood gas analysis, glycosylated hemoglobin (HbA1C%), sputum smear, sputum culture, and anti-infection and related therapy were recorded. All patients were classified into three groups based on bed rest duration, including short-term (<1 month), mid-term (1-12 months), and long-term (> 12 months). The correlation between the bedridden time and the patients' basic characteristics, disease history, laboratory examination results, pathogen, anti-infection, and related therapy were evaluated. The risk factors related to the prognosis of the disease were investigated.

RESULTS

Prolonged bed rest in patients led to an increase in hospitalization time, mortality rates, and decreased serum albumin levels (P < 0.05). Sputum bacteriological culture results showed that, with bed rest prolongation, the proportion of Pseudomonas aeruginosa and fungal infections increased. Binomial logistic regression of pulmonary infection prognosis, glucocorticoid use during the anti-infective period, prolonged bedridden time, and serum albumin level showed that intravenous use of glucocorticoid during anti-infective treatment, bed rest > 1 year, and low serum albumin level were related to poor prognosis.

CONCLUSION

Elderly hip fracture patients with prolonged bedridden time had an increased chance of opportunistic pulmonary infection and decreased nutritional status. Glucocorticoids should be used cautiously.

The Journey of Recovery: Caregivers' Perspectives From a Hip Fracture Telerehabilitation Clinical Trial

OBJECTIVE

The objective was to explore family caregivers' perspectives of the recovery process of older adults with hip fracture and describe experiences from caregivers who: (1) used the online intervention, or (2) received home-based care provided by the Andalusian Public Health Care System.

METHODS

This was an exploratory secondary study with informal family caregivers who had an older adult family member with hip fracture enrolled in a novel telerehabilitation (telerehab) clinical trial. Forty-four caregivers of older adults with hip fracture were interviewed at 6 to 9 months after their family member's hip fracture.

RESULTS

Caregivers shared concerns of family members' survival and recovery; they recounted increased stress and anxiety due to the uncertainty of new tasks associated with providing care and the impact on their lifestyle. Although most caregivers were satisfied with the health care received, they made suggestions for better organization of hospital discharge and requests for home support. The main reasons why caregivers and their family member chose the telerehab program were to enhance recovery after fracture, gain knowledge for managing at home, and because of the convenience of completing the exercises at home. There were more family caregivers in the control group who expressed a high level of stress and anxiety, and they also requested more social and health services compared with caregivers whose family member received telerehab.

CONCLUSION

Family caregivers are an essential component of recovery after hip fracture by providing emotional and physical support. However, future clinical interventions should evaluate person-centered interventions to mitigate possible stress and anxiety experienced by family caregivers.

IMPACT

Family caregivers' perspectives are necessary in the co-design of management strategies for older adults after hip fracture.

Physical Therapy Management of Older Adults With Hip Fracture

Hip fracture is a leading cause of profound morbidity in individuals aged 65 years and older, ranking in the top 10 causes of loss of disability-adjusted life-years for older adults. Worldwide, the number of people with hip fracture is expected to rise significantly due to the aging population and other factors. Physical therapist management is recommended within medical, surgical, and multidisciplinary clinical practice guideline (CPGs) and is considered to be the standard of care in rehabilitation for people with hip fracture. The goal of this CPG was to review the evidence relevant to physical therapist management and to provide evidence-based recommendations for physical therapy diagnosis, prognosis, intervention, and assessment of outcome in adults with hip fracture.

Inferior Outcome after Unstable Trochanteric Fracture Patterns Compared to Stable Fractures in the Elderly

BACKGROUND

Various risk factors affecting outcome of elderly patients after proximal femur fracture have been identified. The present study aims to evaluate the impact of the fracture pattern in trochanteric fractures on postoperative mobility and complications.

METHODS

Ninety-two patients with a mean age of 84 years were included. According to the revised AO/OTA classification, fractures were divided into stable (AO 31A1) and unstable (AO 31A2/3) patterns. A follow-up examination was performed 12 months after cephalomedullary fixation to assess outcome parameters for mobility/activities of daily living (Parker Mobility Score (PMS)/Barthel Index (BI)) and complications (increase in requirement of care, hospital readmission, mortality rate).

RESULTS

At follow-up, patients with unstable trochanteric fracture patterns presented with lower PMS and BI compared to stable fractures (p < 0.05). Further, higher requirement of care and higher readmission rates compared to stable patterns were observed.

CONCLUSION

Unstable trochanteric fractures presented inferior outcome compared to simple fracture patterns. This might be explained by the increasing surgical trauma in unstable fractures as well as by the mechanical impact of the lesser trochanter, which provides medial femoral support and is of functional relevance. Subsequent studies should assess if treatment strategies adapted to the specific fracture pattern (refixation of lesser trochanter) influence outcome in unstable trochanteric fractures.

Incidence, morbidity and mortality of hip fractures over a period of 20 years in a health area of Southern Spain

OBJECTIVE

To evaluate the incidence of osteoporotic hip fracture in the Macarena Health Area (Seville).

SETTING AND PARTICIPANTS

This was a prospective observational study that collected all osteoporotic hip fractures that occurred between March 2013 and February 2014 at the Clinical Unit of Traumatology and Orthopaedics. All cases collected during the first 6 months of the study were followed for 1 year after the occurrence of the event.

OUTCOME MEASURES

We evaluated the incidence of osteoporotic hip fractures in the Macarena Health Area (Seville) from 1 March 2013 to 28 February 2014, and we compared the incidence with that in 2 previous studies carried out with the same methodology in 1994 and 2006. Furthermore, we calculated the morbidity and degree of disability 1 year after the fracture occurred and determined mortality and the associated factors.

RESULTS

The overall incidence was 228 per 100 000 individuals/year (95% CI 204.5 to 251.6), and the incidence was higher in women than in men. In women, the incidence rate decreased in all age groups over time, while in men, the incidence rate increased. The mortality rate 1 year after the episode was 27.2%. The factors associated with overall mortality were a body mass index below 25 kg/m², renal failure and low plasma proteins.

CONCLUSIONS

Our results show a high incidence of osteoporotic hip fracture that is increasing in men, and in men it is associated with a higher mortality than in women. There is room to improve the modifiable factors associated with mortality and the available rehabilitation interventions to reduce the disability associated with these fractures.

Factors associated with one-year mortality of patients admitted with fragility hip fracture: a follow-up study in Southern Sri Lanka

One hundred and eighty patients with incident fragility hip fracture admitted to a tertiary care center in Sri Lanka were followed up for 12 months. When compared with those survived, patients who died were older and had higher comorbidity and physical impairment, before fracture and at discharge from the hospital.

INTRODUCTION

This study examined the factors that are associated with mortality within the first 12 months, of patients admitted with fragility hip fracture to a tertiary care center in Southern Sri Lanka.

METHODS

One hundred and eighty consecutive patients admitted with new fragility hip fracture were followed up for 12 months post-fracture. Apart from age and gender, information related to physical dependency (prefracture and at discharge) and comorbidity were collected from all subjects.

RESULTS

Of 180 patients (149women), 107 had surgery while the rest were managed conservatively. Mean (SD) age of study subjects was 76.5 (9.2 years). Thirty-three patients died within the first 12 months were older and had higher comorbidity and physical impairment before fracture and at discharge from the hospital, when compared with those survived. Relative risk (95% CI, p value) of death for being a male was 6.52 (3.18-11.5, < 0.001) and corresponding values for conservative management were 6.59 (2.86-15.2, < 0.001). In the ROC analysis, in which mortality/survival was taken as state variable, AUCs for age, Charlson index, age-adjusted Charlson index, and Barthel index before fracture and Barthel index at discharge were 0.77 (0.04), 0.79 (0.04), 0.70 (0.05), 0.67 (0.05), and 0.76 (0.04 ) (p < 0.01 for all). Age-adjusted odd ratios (95% CI) of ACCI, CCI, surgical management, and Barthel index before fracture and at discharge were 2.21 (1.37 to 3.57), 2.37 (1.46 to 3.83), 0.18 (0.06 to 0.53), 0.91 (0.85 to 0.97), and 0.93 (0.88 to 0.99), respectively (p < 0.05 for all).

CONCLUSIONS

We conclude that advanced age, male gender, higher comorbidity, physical impairment before and after fracture, and conservative management lead to a higher risk of mortality in patients admitted with incident fragility hip fracture. This study can be used as a platform for future research in this area in Sri Lanka.

Weight changes and mobility in the early phase after hip fracture in community-dwelling older persons

Aim

To investigate body weight changes and their effect on mobility during the first two months following a hip fracture.

Findings

The loss of body weight was observed in three out of four patients in the early phase after hip fracture and was associated with decreased mobility measured by the NMS.

Message

Bodyweight loss is common and may further reduce mobility in hip fracture patients, but these findings need more research.

Purpose

Hip fractures in older persons are associated with reduced mobility and loss of independence. Few studies address the nutritional status and mobility in the early phase after hip fracture. The objective of the present study was, therefore, to investigate weight changes and their effect on mobility during the first two months following hip fracture in community-dwelling older persons without dementia.

Methods

Patients (> 60 years) admitted for a first hip fracture were recruited from two tertiary referral hospitals in Bergen, Norway. The patients' weights and dietary intakes were determined in the hospital and at home after two months. Mobility was assessed based on the New Mobility Score (NMS) (scale 0–9, with values > 5 regarded as sufficient mobility).

Results

We included 64 patients (median age 80 years, 48 women, 16 men) with information on weight collected in the hospital. Follow-up measurements were available for 32 patients, corresponding to an attrition rate of 50%. The patients had a median weight loss of 1.8 kg (IQR = − 3.7, 0 kg). Most of them had reduced mobility at two months after the surgery [median NMS = 5 (IQR = 3–6)]. Both age and the weight change after surgery were predictors of the NMS at follow-up.

Conclusion

Bodyweight loss was observed in three out of four patients in the early phase after hip fracture and was associated with decreased mobility measured by the NMS. The results should be interpreted with caution as half of the patients dropped out of the study and did not participate in the follow-up visit.

Factors Affecting Compliance With Weight-Bearing Restriction and the Amount of Weight-Bearing in the Elderly With Femur or Pelvic Fractures

OBJECTIVE

To determine the factors affecting the amount of weight-bearing during gait training in the elderly patients who underwent internal fixation after femur or pelvic fractures and how well they performed the weight-bearing restriction as directed by the physiatrist.

METHODS

In this retrospective chart review study, we measured the amount of weight-bearing on the affected side in 50 patients undergoing internal fixation surgery and rehabilitation after femur or pelvic fracture using a force plate. Patients receiving non-weight-bearing or partial weight-bearing education were considered to perform weight-bearing restriction well when the amount of weight-bearing was <50 lb. Furthermore, regression analysis was performed to determine the effects of postoperative complications, age, cognitive function, and pain on weightbearing restriction.

RESULTS

Variables affecting the amount of weight-bearing were age (r=0.581, p<0.001), weight-bearing education type (r=0.671, p<0.001), manual muscle strength of hip flexion on the non-affected side (r=-0.296, p=0.037), hip abduction (r=-0.326, p=0.021), knee extension (r=-0.374, p=0.007), ankle plantar flexion (r=-0.374, p=0.008), right hand grip strength (r=-0.535, p<0.001), Korean version of Mini-Mental State Examination (r=-0.496, p<0.001), Clinical Dementia Rating (r=0.308, p=0.03), and pain visual analog scale scores (r=0.318, p=0.024). The significant predictor of the amount of weight-bearing among these variables was age (β=0.448, p=0.001). The weight-bearing restriction adherence rate was significantly lower, at 22%, for patients aged ≥65 years as compared to 73% for those <65 years.

CONCLUSION

Age was a major variable affecting the amount of weight-bearing. Compliance with weight-bearing restriction was significantly lower in patients aged ≥65 years than in patients <65 years.

Comparison of the Charlson Comorbidity Index with the ASA score for predicting 12-month mortality in acute hip fracture

BACKGROUNDS

The ASA (American Society of Anaesthesiologists) Score is the current standard for measuring comorbidity in the Australian Hip Fracture registry, however it has never been validated for this purpose. Subsequently, a more appropriate and useful measure should be investigated. This study aimed to compare the ASA and Charlson Comorbidity Index (CCI) scores in predicting 12-month mortality following acute hip fracture.

METHODS

A retrospective analysis was performed on an audit database of patients who were admitted to an orthogeriatric unit in a public metropolitan hospital from November 2010 to October 2011. 12-month mortality data was linked through a dual search of Queensland Health and mortality registry data. The Charlson comorbidity index was retrospectively applied. Demographics (age, gender, admission residence) and covariates including ASA, CCI, fracture type, fixation type, cognitive impairment on admission, BMI and time to surgery were analysed with logistic regression. ROC curve analysis was performed to assess varying thresholds for each comorbidity system.

RESULTS

A total of 320 patients were available for audit. Unadjusted bivariate analysis demonstrated significant difference between groups regarding increased age (p = 0.004), ASA score (p<0.001), CCI (p = 0.002), age-adjusted CCI (p = 0.002) and admission from a care facility (p<0.001). Logistic regression analysis demonstrated that only ASA (p<0.001) and admission from a care facility (p<0.001, OR=3.36, 95% CI = 1.9 - 6.0) independently predicted 12-month mortality; CCI was not a significant predictor in any models (p = 0.827, age-adjusted CCI: p = 0.864). Using ROC analysis, the ASA (AUC=0.668) outperformed either CCI (AUC=0.607 (CCI), AUC=0.614 (CCI age-adjusted).

CONCLUSIONS

The ASA score is independently associated with 12-month mortality; this was not replicated using either version of the CCI. The data does not suggest using the CCI in registry level datasets for the purposes of predicting 12-month mortality.

Mortality after osteoporotic hip fracture: incidence, trends, and associated factors

BACKGROUND

It is known that mortality after hip fracture increases compared to the general population; the trend in mortality is a controversial issue. The objective of this study is to examine incidence, trends, and factors associated with mortality in patients with osteoporotic hip fractures.

METHODS

This is a retrospective cohort study that uses the Registry for Hospital Discharges of the National Health System of our hospital. Patients older than 45 having an osteoporotic hip fracture between 1999 and 2015 were identified. Demographic data and comorbidities were obtained. A survival analysis was performed (Cox regression and Kaplan-Meier). Incidence rate, standardized death rate (SDR), trend (Poisson regression), and risk (hazard ratio) were calculated.

RESULTS

During 1999-2015, in our hospital, there were a total of 3992 patients admitted due to osteoporotic hip fracture. Out of these 3992 patients, 3109 patients (77.9%) were women with an average age of 84.47 years (SD 8.45) and 803 (22.1%) were men with an average age of 81.64 years (SD 10.08). The cumulative incidence of mortality was 69.38%. The cumulative mortality rate for 12 months was 33%. The annual mortality was 144.9/1000 patients/year. The 1-year mortality rate increased significantly by 2% per year (IRR 1.020, CI95% 1.008-1.033). The median overall survival was 886 days (CI95% 836-951). The probability of mortality density for a period of 10 years following a hip fracture was 16% for women and 25% for men (first 90 days). The SDR was 8.3 (CI95% 7.98-8.59). Variables that showed statistically significant association with mortality were aged over 75, masculine, institutionalization, mild to severe liver disease, chronic kidney disease, COPD, dementia, heart failure, diabetes, the Charlson Index > 2 , presence of vision disorders and hearing impairment, incontinence, and Downton scale.

CONCLUSIONS

For the last 17 years, an increase of mortality for patients with hip fracture and a higher mortality rate in men than in women were observed. Institutionalization combined with comorbidities is associated with a higher mortality.

[A new continuous gait analysis system for ankle fracture aftercare]

BACKGROUND

Correct aftercare following lower extremity fractures remains a controversial issue. Reliable, clinically applicable weight-bearing recommendations have not yet been defined. The aim of the current study was to establish a new gait analysis insole during physical therapy aftercare of ankle fractures to test patients' continuous, long-term compliance to partial weight-bearing restrictions and investigate whether patients can estimate their weight-bearing compliance.

MATERIALS AND METHODS

The postoperative gait of 14 patients after operative treatment of Weber B-type ankle fractures was monitored continuously for six weeks (OpenGO, Moticon GmbH, Munich). All patients were instructed and trained by physical therapists on how to maintain partial weight-bearing for this time. Discontinuous (three, six and twelve weeks) clinical (patient questionnaire, visual analogue pain score [VAS]) and radiographic controls were performed.

RESULTS

Despite the set weight-bearing limits, individual ranges for overall weight-bearing (range 5-107% of the contralateral side) and patient activity (range 0-366 min/day) could be shown. A good correlation between weight-bearing and pain was seen (r_s = -0.68; p = <0.0001). Patients significantly underestimated their weight-bearing time over the set limit (2.3 ± 1.4 min/day vs. real: 12.6 ± 5.9 min/day; p < 0.01).

CONCLUSIONS

Standardized aftercare protocols and repeated training alone cannot ensure compliance to postoperative partial weight-bearing. Patients unconsciously increased weight-bearing based on their pain level. This study shows that new, individual and possibly technology-assisted weight-bearing regimes are needed. The introduced measuring device is feasible to monitor and steer patient weight-bearing during future studies.

Nonunion and Reoperation After Internal Fixation of Proximal Femur Fractures: A Systematic Review

Nonunion after fixation of a proximal femur fracture is associated with increased disability, pain, and cost to both patient and health care system. Understanding the effect of fixation method and fracture pattern on healing is important to optimize healing. The authors evaluated surgical healing, nonunion rate, and reoperation rate after internal fixation of proximal femur fracture, especially since the year 2000. They performed a systematic review of all published records from PubMed, Embase, and the Cochrane Review system. The burden of proximal femoral fracture extends beyond acute disability, as it carries a high risk of long-term morbidity and mortality. Choice of fixation method for high-risk fractures is critical to reduce nonunion and reoperation rates. [Orthopedics. 2019; 42(2):e162-e171.].

Influence of mobilization and weight bearing on in-hospital outcome in geriatric patients with hip fractures

INTRODUCTION

Early recovery of mobilization after a fracture of the hip is associated with improved long-term ability to walk, lower complication rates, and mortality. In this context, early mobilization and full weight bearing are favorable. The aim of this study was (1) to analyze the influence of time between operation and first mobilization on in-hospital outcome and (2) the influence of early mobilization, full weight bearing, and ASA on pain, mobility of the hip, and ability to walk during the in-hospital phase of recovery.

METHODS

This is a retrospective in-hospital study of 219 patients aged 70 years or older who were treated with surgery after a hip fracture. Data were collected by a review of medical records. The outcomes were mortality, complications, length of stay, and the Merle d'Aubigné score which evaluates pain, mobility of the hip, and ability to walk. Factors were sought in bivariate and multivariate analyses.

RESULTS

A shorter time between operation and first mobilization was significantly associated with lower in-hospital mortality and complications. Early mobilization (within 24 h after the operation) and full weight bearing had no influence on pain, mobility of the hip, and ability to walk as well as length of stay in our cohort. Fracture type and treatment influenced mobility of the hip, while age as well as physical health status affected the ability to walk.

DISCUSSION

Patients with femoral neck fractures, respectively after total hip arthroplasty, had less pain and showed better mobility of the hip and ability to walk during hospitalization than patients with trochanteric fractures; these results were irrespective of early vs. late mobilization and full vs. partial weight bearing. Foremost, a shorter time between operation and first mobilization is associated with lower complication and mortality rates.

Low predictive power of comorbidity indices identified for mortality after acute arthroplasty surgery undertaken for femoral neck fracture

Aims

Our aim was to examine the Elixhauser and Charlson comorbidity indices, based on administrative data available before surgery, and to establish their predictive value for mortality for patients who underwent hip arthroplasty in the management of a femoral neck fracture.

Patients and Methods

We analyzed data from 42 354 patients from the Swedish Hip Arthroplasty Register between 2005 and 2012. Only the first operated hip was included for patients with bilateral arthroplasty. We obtained comorbidity data by linkage from the Swedish National Patient Register, as well as death dates from the national population register. We used univariable Cox regression models to predict mortality based on the comorbidity indices, as well as multivariable regression with age and gender. Predictive power was evaluated by a concordance index, ranging from 0.5 to 1 (with the higher value being the better predictive power). A concordance index less than 0.7 was considered poor. We used bootstrapping for internal validation of the results.

Results

The predictive power of mortality was poor for both the Elixhauser and Charlson comorbidity indices (concordance indices less than 0.7). The Charlson Comorbidity Index was superior to Elixhauser, and a model with age and gender was superior to both indices.

Conclusion

Preoperative comorbidity from administrative data did not predict mortality for patients with a hip fracture treated by arthroplasty. This was true even if association on group level existed.

Relative survival following hemi-and total hip arthroplasty for hip fractures in Sweden

BACKGROUND

Hip fractures are a common problem in the ageing population. Hip arthroplasty is the common treatment option for displaced intracapsular neck of femur fractures. Even though hip replacements are successful in restoring mobility, reducing pain and diminishing loss of health-related quality of life, the potential impact of a hip fracture on life expectancy as well as the postoperative mortality need consideration. The purpose of this study was to describe the mid-term relative survival rate for a cohort of Swedish patients whom underwent total- or hemiarthroplasty surgery following hip fracture. We also explored whether the survival rate is prosthesis-type specific and influenced by comorbidities, sex, socioeconomic and surgical factors.

METHODS

Using prospectively collected information of the Swedish Hip Arthroplasty Register-linked database we identified 43,891 patients operated between 2005 and 2012. Patient- and surgery-specific data in combination with socio-economic data were available for this analysis. We studied relative survival rate and used multivariable modelling with Cox Proportional Hazards Model in Transformed Time.

RESULTS

Compared to the Swedish general population the baseline excess hazard was very high in the first half year after the operation, thereafter the excess hazard decreased but remained non-negligible through the 8 years' follow-up period. The mortality rate of males was higher compared to women. Higher Elixhauser comorbidity index (ECI) was associated with worsening survival. However, patients who had ECI = 0 had higher mortality than patients with ECI =1 the first 420 days post fracture. Patients with a hemiarthroplasty had a worse survival than patients with a total hip arthroplasty. Of the hospital types considered university hospitals had lower survival rate. Younger patients had a greater loss of expected life span than patients who suffer hip fracture in their more advanced ages.

CONCLUSIONS

Swedish hip fracture patients who undergo arthroplasty surgery had a high excess hazard of dying in the first half year following surgery, and this excess hazard never subsided to negligible levels at least up to 8 years after surgery. Interestingly having no prior record of illnesses worsened the initial mortality. Men living alone had the highest long-term excess mortality.

A home-based tele-rehabilitation protocol for patients with hip fracture called @ctivehip

Home-based tele-rehabilitation programs are under development and may be a future option for some patients. The objectives of this non-randomized clinical trial are to design a home-based multidisciplinary tele-rehabilitation protocol for patients with hip fracture, and to compare this protocol versus the home-based usual outpatient rehabilitation protocol. Seventy patients treated for an acute hip fracture, aged 65 years or older, with a high pre-fracture functional level (Functional Independence Measure score >90), without severe cognitive impairment, absence of terminal disease, discharged to their own home or a relativés home postoperatively, allowed weight-bearing, and with signed informed consent, will be allocated into a tele-rehabilitation group (n = 35) or a control group (n = 35). The inclusion criterion for the intervention group will be to have a caregiver with the ability to access the Internet who is willing to perform exercises and activities with the patient at home. The intervention includes a program of physical exercise and occupational therapy (five weekly sessions during 12 weeks), and recommendations for patients and their caregivers, all delivered through a website. The patient's functional level (Functional Independence Measure), quality of life (Euro-Qol), physical performance (Timed Up and Go), caregiver burden (Zarit Interview), and other descriptive data will be assessed at hospital discharge, 4 weeks, and 12 weeks. This project will add to the knowledge concerning the feasibility of tele-rehabilitation as an option to promote recovery of the pre-fracture functional level for some patients with a hip fracture. ClinicalTrials.gov Identifier: NCT02968589NCT.

Physiotherapy following fragility fractures

Physiotherapy can play a vital role in the pathway of care of people after fragility fracture and includes interventions of early mobilisation and prescription of structured exercise programmes for maximising functional recovery and reducing the risk of falls and further fractures. Although the optimal nature of physiotherapist interventions after hip and vertebral fracture requires further investigation in large-scale trials, evidence supports the prescription of high-intensity and extended exercise interventions. This article will overview interventions in the acute and chronic phases after hip fractures, interventions after vertebral fracture and the role of physiotherapy in the prevention of further fractures.

Characteristics and Outcomes of Patients in Rehabilitation with Hip Fracture: A Retrospective Chart Review

ABSTRACTHip fracture rehabilitation has two streams: high tolerance short duration (HTSD) and low tolerance long duration (LTLD). This study examined patient characteristics and outcomes in HTSD and LTLD associated with length of stay (LOS) and discharge destination. We retrospectively examined patients' medical charts following hip fracture surgery and collected demographic, functional, and health characteristics. A statistical analysis was done to describe the differences between HTSD (n = 73) and LTLD (n = 57) patient characteristics and their relationship with LOS and discharge destination. Those in LTLD were significantly older, less independent with prefracture bathing and instrumental activities of daily living, had lower Functional Independence Measure (FIM) admission scores, and more co-morbidities. Higher FIM motor score on admission in HTSD and greater change in FIM total score in LTLD was significantly correlated with discharge home. Diabetes in LTLD and lower total admission FIM in HTSD was significantly associated with increased LOS.

The Effectiveness of Osteoporosis Screening and Treatment in the Midwest

Introduction:

With osteoporosis on the rise across the United States, the goal of this prospective study is to determine the effectiveness of our Midwest level-1 trauma center in diagnosing, treating, and educating osteoporosis patients after fracture with the use of questionnaires. Secondarily, we aimed to identify barriers that prevent our patients from complying with bone health recommendations.

Methods:

One hundred participants (≥55 years) were given 2 questionnaires (Fracture Risk Assessment Tool and a study-specific questionnaire) that were administered during the patient’s visit to the orthopedic trauma clinic. A group of patients diagnosed with osteoporosis was compared to a group of patients not diagnosed with osteoporosis. Statistical analyses were performed using SPSS 24 (IBM Corp, Chicago, Illinois).

Results:

Patients who had been diagnosed with osteoporosis were significantly older (72.7 vs 66.5, P = .009) and more were women (86.2% vs 66.2%, P = .043). Significantly, fewer patients without the diagnosis of osteoporosis had a history of fragility fracture (56.3%) compared to 92.9% of those diagnosed with osteoporosis (P < .001). Of those with dual-energy X-ray absorptiometry (DXA) recommended by a healthcare provider, 20 (55.6%) of those without the diagnosis of osteoporosis and 13 (52%) of those with the diagnosis of osteoporosis had DXA screening before their fragility fracture (P = .499). More patients diagnosed with osteoporosis (93.1%) were taking calcium and vitamin D supplementation compared to 66.2% of those without the diagnosis of osteoporosis (P = .005). Only 37.9% of patients with the diagnosis of osteoporosis were receiving US Food and Drug Administration–approved medications for the management of their disease.

Discussion:

In patients without previous osteoporosis diagnosis, 59 (83.1%) of the 71 claimed that they did not receive any preventative education about osteoporosis, while 21 (72.4%) of the 29 patients with the diagnosis of osteoporosis claimed that they did not receive a preventative education (P = .165). Both groups lacked optimum diagnosis, treatment, and education of osteoporosis.

Conclusion:

Our study highlights the need for a deliberate effort of a multidisciplinary team to focus efforts in all stages of osteoporosis management.

Preventable risk factors of mortality after hip fracture surgery: Systematic review and meta-analysis

OBJECTIVE

Although many studies have reported risk factors of mortality following hip fracture surgery, the preventable risk factors of mortality following hip fracture surgery have not been well-identified. The aim of this study was to identify the preventable risk factors of mortality following hip fracture surgery.

METHODS

We searched PubMed, Web of Science, Google scholar, and the Chinese National Knowledge Infrastructure (CNKI) databases from January 1997 to March 2017 for studies reporting risk factors of mortality following hip fracture surgery. The primary outcomes assessed in this meta-analysis were time to surgery, residential status, smoking, cardiovascular disease, pulmonary disease, diabetes, and malignancy. All analyses were conducted using Stata/SE version 11.0 software.

RESULTS

Sixteen studies involving 25 349 patients meeting the inclusion criteria were included. Statistically significant associations between the mortality after hip fracture surgery and the risk factors, including the time to surgery (>2days/<2days) (odds ratio[OR] = 1.91; 95%CI, 1.14-3.18; P = 0.013), residential status (nursing home/home) (OR = 1.97; 95%CI, 1.02-3.78; P = 0.043), cardiovascular disease (OR = 1.14; 95%CI, 1.03-1.26; P = 0.012), pulmonary disease (OR = 1.52; 95%CI, 1.37-1.69; P < 0.001), diabetes (OR = 1.41; 95%CI, 1.19-1.67; P < 0.001), and malignancy (OR = 2.99, 95%CI, 1.14-7.83; P = 0.013) were established. However, the available data failed to demonstrate an association between the mortality, and time to surgery (>1day/<1day) (OR = 1.25; 95%CI, 0.93-1.66; P = 0.136) and smoking (OR = 0.89; 95%CI, 0.69-1.14; P = 0.340).

CONCLUSION

This meta-analysis explicitly indicated that malignancy, nursing home residence, time to surgery (>2days/<2days), pulmonary disease, diabetes, and cardiovascular disease significantly increased the risk of mortality after hip fracture surgery. These preventable risk factors may be used to create algorithms that are more effective and pertinent to reduce the mortality following hip fracture surgery.

Putting the Brakes on Breaks: Osteoporosis Screening and Fracture Prevention

Introduction

This prospective study sought to implement a screening tool to identify and risk stratify at-risk patients for osteoporosis and evaluate patient knowledge of osteoporosis and fragility fractures in an orthopedic trauma clinic affiliated with a level 1 trauma academic center.

Methods

Of 297 eligible patients, 291 were screened and risk stratified. Patients completed an osteoporosis screening questionnaire and were risk stratified. Lifestyle advice was given to patients at low fracture risk. A dual-energy X-ray absorptiometry scan was ordered for patients at intermediate fracture risk. A referral was initiated for treatment to a bone health specialist in high fracture risk patients. Twenty patients completed a knowledge-based pretest/posttest.

Results

A total of 291 patients were screened, which represented 97.7% of patients over the age of 50. Of those patients, 165 (56.7%) patients met criteria for further osteoporosis evaluation as they were considered either intermediate or high risk for future fractures. One hundred thirty-six (82.4%) patients were referred for bone mineral density evaluation. For the knowledge-based evaluation portion, patients had a 33% gain in knowledge (P = .0004). The largest knowledge deficit identified pertained to osteoporosis risk factors and lifestyle management.

Discussion

The use of an osteoporosis screening questionnaire in the orthopedic trauma clinic produced clinically significant improvement in identification of at-risk patients. A lack of knowledge regarding osteoporosis and fragility fractures was found to exist among these patients.

Conclusion

The implementation of an osteoporosis screening tool to identify, risk stratify, and treat patients with osteoporosis and related fragility fractures can be successfully integrated into a busy clinical practice.

Mortality by Timing of Hip Fracture Surgery: Factors and Relationships at Play

In hip fracture care, it is disputed whether mortality worsens when surgery is delayed. This knowledge gap matters when hospital managers seek to justify resource allocation for prioritizing access to one procedure over another. Uncertainty over the surgical timing-death association leads to either surgical prioritization without benefit or the underuse of expedited surgery when it could save lives. The discrepancy in previous findings results in part from differences between patients who happened to undergo surgery at different times. Such differences may produce the statistical association between surgical timing and death in the absence of a causal relationship. Previous observational studies attempted to adjust for structure, process, and patient factors that contribute to death, but not for relationships between structure and process factors, or between patient and process factors. In this article, we (1) summarize what is known about the factors that influence, directly or indirectly, both the timing of surgery and the occurrence of death; (2) construct a dependency graph of relationships among these factors based explicitly on the existing literature; (3) consider factors with a potential to induce covariation of time to surgery and the occurrence of death, directly or through the network of relationships, thereby explaining a putative surgical timing-death association; and (4) show how age, sex, dependent living, fracture type, hospital type, surgery type, and calendar period can influence both time to surgery and occurrence of death through chains of dependencies. We conclude by discussing how these results can inform the allocation of surgical capacity to prevent the avoidable adverse consequences of delaying hip fracture surgery.

Effectiveness of acute in-hospital physiotherapy with knee-extension strength training in reducing strength deficits in patients with a hip fracture: A randomised controlled trial

Question

Is acute in-hospital physiotherapy with additional progressive knee-extension strength training (ST) of the fractured limb more effective in reducing knee-extension strength deficit at follow-up compared to physiotherapy without strength training in patients with a hip fracture?

Design

Assessor blinded, randomised controlled trial with intention-to-treat analysis.

Participants

90 patients with a hip fracture admitted to an acute orthopaedic Hip Fracture Unit at a university hospital between October 2013 and May 2015.

Intervention

Daily physiotherapy with or without progressive knee-extension strength training (10RM), 3 x 10 repetitions, of the fractured limb using ankle weight cuffs conducted by ward physical therapists during hospital stay.

Outcome measures

Primary outcome was the change in maximal isometric knee-extension strength in the fractured limb in percentage of the non-fractured limb from inclusion to postoperative day 10 or discharge (follow-up). Secondary outcome was Timed Up and Go test measured early after surgery and at follow-up.

Results

In the intention-to-treat analysis of between-group differences, the primary outcome improved 8.1% (95% CI -2.3; 18.4) by additional strength training from baseline to follow-up. In the per-protocol analysis of non-missing data, significant between-group improvements by 10.5% (95% CI 0.3; 20.7) were found in favour of additional ST. No significant between-group differences were found in any secondary outcome.

Conclusion

Physiotherapy with addition of 5 sessions of ST yielded no additional improvements compared to physiotherapy without strength training in reducing the knee-extension strength deficit at follow-up in patients with a hip fracture. It is debatable whether larger improvements than the observed 8–10% can be expected given that only five exercise sessions, on average, were completed. In fragile patients with a hip fracture in the acute phase, where the ability to participate in functional exercise is compromised, we still consider early strength training a possibility to improve outcomes of clinical importance, given the results of the per-protocol analysis. The present data provides an important basis and call for future investigations including longer term interventions.

Trends in hip fracture rates in Taiwan: a nationwide study from 1996 to 2010

There was an initial increase and a later decrease in hip fracture rates in Taiwan between 1996 and 2010 (457.9 to 390.0 fractures per 100,000 people per year). Mortality rates decreased but re-emerged later (2.26 to 1.91 deaths per 100 hip fracture admissions). The turning point for change in trends was 2003.

INTRODUCTION

Fractures of the proximal femur remain a major cause of mortality and morbidity. We aimed to examine recent trends in hip fracture rates, in-hospital mortality rates, and length of hospital stay (LOS) due to hip fractures in people aged 55 and over in Taiwan.

METHODS

This is a time-trend study. We used data from the National Health Insurance Research Database between 1996 and 2010 in Taiwan. Insurants aged 55 and over were included. The outcome measures were age-adjusted hip fracture rates, age-adjusted in-hospital mortality rates, and LOS due to hip fractures. We classified hip fractures into femoral neck, trochanteric, and subtrochanteric fractures.

RESULTS

We identified 250,919 hospitalizations for hip fractures. The total number of hip fractures increased steadily from 12,479 to 19,841 cases. There was a trend towards initial increase and then later decrease in hip fracture rates (from 457.9 to 390.0 fractures per 100,000 people per year). LOS decreased by 46.5 % (17.53 to 9.38 days). By contrast, mortality rates for hip fractures decreased initially, but re-emerged later with a total decrement of 15.5 % (2.26 to 1.91 deaths per 100 hip fracture admissions). Women outnumbered men in all types of hip fractures, but men had higher in hospital mortality rates. LOS was similar between genders and among age groups. The turning point for change in trends was year 2003.

CONCLUSIONS

While LOS shortened gradually since 1996, the absolute number of hip fractures in Taiwan continues to rise. There is still room for improvement in reducing mortality due to hip fractures.

Comparison of predictors of hip fracture and mortality after hip fracture in community-dwellers with and without Alzheimer's disease - exposure-matched cohort study

BACKGROUND

Dementia, with Alzheimer's disease (AD) being the most common form, is a major hip fracture risk factor, but currently it is not known whether the same factors predict hip fracture among persons with and without dementia/AD. We compared the predictors of hip fracture and mortality after hip fracture in persons with and without AD.

METHODS

An exposure-matched cohort of all community-dwellers of Finland who received a new clinically verified AD diagnosis in 2005-2011 and had no history of previous hip fracture (N = 67,072) and an age, sex, and region-matched cohort of persons without AD (N = 67,072). Associations between sociodemographic characteristics, comorbidities and medications and risk of hip fracture and mortality after hip fracture were assessed with Cox regression.

RESULTS

As expected, the incidence of hip fractures in 2005-2012 (2.19/100 person-years vs 0.90/100 person-years in the non-AD cohort), as well as mortality after hip fracture (29/100 person-years vs 23/100 person-years in the non-AD cohort) were higher in the AD cohort. This difference was evident regardless of the risk factors. Mental and behavioural disorders (adjusted hazard ratio; HR 95% confidence interval CI: 1.16, 1.09-1.24 and 1.71, 1.52-1.92 in the AD and non-AD-cohorts), antipsychotics (1.12, 1.04-1.20 and 1.56, 1.38-1.76 for AD and non-AD-cohorts) and antidepressants (1.06, 1.00-1.12 and 1.34 1.22-1.47 for AD and non-AD-cohorts) were related to higher, and estrogen/combination hormone therapy (0.87, 0.77-0.9 and 0.79, 0.64-0.98 for AD and non-AD-cohorts) to lower hip fracture risk in both cohorts. Stroke (1.42, 1.26-1.62), diabetes (1.13, 0.99-1.28), active cancer treatment (1.67, 1.22-2.30), proton pump inhibitors (1.14, 1.05-1.25), antiepileptics (1.27, 1.11-1.46) and opioids (1.10, 1.01-1.19) were associated with higher hip fracture risk in the non-AD cohort. Similarly, the associations between mortality risk factors (age, sex, several comorbidities and medications) were stronger in the non-AD cohort.

CONCLUSIONS

AD itself appears to be such a significant risk factor for hip fracture, and mortality after hip fracture, that it overrules or diminishes the effect of other risk factors. Thus, it is important to develop and implement preventive interventions that are suitable and effective in this population.

Geriatric orthopedic co-management of older adults with hip fracture: an emerging standard

Hip fracture, a common complication of fall injuries in older adults, often results in high rate of mortality, increased debility, functional loss, and worse quality of life. The value of geriatric teams and model of care for the hip fracture patients have been examined in a number of studies, and even though most studies have demonstrated potential impact in improving outcomes for the hip fracture patients, they are often observational or quasi-experimental designs that are prone to bias. In this editorial, we review the Lancet article by Prestmo and colleagues, a randomized controlled trial that demonstrated improved outcomes for hip fracture patients managed in a geriatric unit.
