Quality of life, morbidity, and mortality after low trauma hip fracture in men

Establishment and validation of an artificial intelligence web application for predicting postoperative in-hospital mortality in patients with hip fracture: a national cohort study of 52 707 cases

BACKGROUND

In-hospital mortality following hip fractures is a significant concern, and accurate prediction of this outcome is crucial for appropriate clinical management. Nonetheless, there is a lack of effective prediction tools in clinical practice. By utilizing artificial intelligence (AI) and machine learning techniques, this study aims to develop a predictive model that can assist clinicians in identifying geriatric hip fracture patients at a higher risk of in-hospital mortality.

METHODS

A total of 52 707 geriatric hip fracture patients treated with surgery from 90 hospitals were included in this study. The primary outcome was postoperative in-hospital mortality. The patients were randomly divided into two groups, with a ratio of 7:3. The majority of patients, assigned to the training cohort, were used to develop the AI models. The remaining patients, assigned to the validation cohort, were used to validate the models. Various machine learning algorithms, including logistic regression (LR), decision tree (DT), naïve bayesian (NB), neural network (NN), eXGBoosting machine (eXGBM), and random forest (RF), were employed for model development. A comprehensive scoring system, incorporating 10 evaluation metrics, was developed to assess the prediction performance, with higher scores indicating superior predictive capability. Based on the best machine learning-based model, an AI application was developed on the Internet. In addition, a comparative testing of prediction performance between doctors and the AI application.

FINDINGS

The eXGBM model exhibited the best prediction performance, with an area under the curve (AUC) of 0.908 (95% CI: 0.881-0.932), as well as the highest accuracy (0.820), precision (0.817), specificity (0.814), and F1 score (0.822), and the lowest Brier score (0.120) and log loss (0.374). Additionally, the model showed favorable calibration, with a slope of 0.999 and an intercept of 0.028. According to the scoring system incorporating 10 evaluation metrics, the eXGBM model achieved the highest score (56), followed by the RF model (48) and NN model (41). The LR, DT, and NB models had total scores of 27, 30, and 13, respectively. The AI application has been deployed online at https://in-hospitaldeathinhipfracture-l9vhqo3l55fy8dkdvuskvu.streamlit.app/ , based on the eXGBM model. The comparative testing revealed that the AI application's predictive capabilities significantly outperformed those of the doctors in terms of AUC values (0.908 vs. 0.682, P <0.001).

CONCLUSIONS

The eXGBM model demonstrates promising predictive performance in assessing the risk of postoperative in-hospital mortality among geriatric hip fracture patients. The developed AI model serves as a valuable tool to enhance clinical decision-making.

Morphological human bone features and demography controlling damage accumulation and fracture: a finite element study

Prediction of bone fracture risk is clinically challenging. Computational modeling plays a vital role in understanding bone structure and diagnosing bone diseases, leading to novel therapies. The research objectives were to demonstrate the anisotropic structure of the bone at the micro-level taking into consideration the density and subject demography, such as age, gender, body mass index (BMI), height, weight, and their roles in damage accumulation. Out of 438 developed 3D bone models at the micro-level, 46.12% were female. The age distribution ranged from 23 to 95 years. The research unfolds in two phases: micro-morphological features examination and stress distribution investigation. Models were developed using Mimics 22.0 and SolidWorks. The anisotropic material properties were defined before importing into Ansys for simulation. Computational simulations further uncovered variations in maximum von-Misses stress, highlighting that young Black males experienced the highest stress at 127.852 ± 10.035 MPa, while elderly Caucasian females exhibited the least stress at 97.224 ± 14.504 MPa. Furthermore, age-related variations in stress levels for both normal and osteoporotic bone micro models were elucidated, emphasizing the intricate interplay of demographic factors in bone biomechanics. Additionally, a prediction equation for bone density incorporating demographic variables was proposed, offering a personalized modeling approach. In general, this study, which carefully examines the complexities of how bones behave at the micro-level, emphasizes the need for an enhanced approach in orthopedics. We suggest taking individual characteristics into account to make therapeutic interventions more precise and effective.

Audit on the Adequacy of Consenting Practices for Neck of Femur Fracture Surgeries

INTRODUCTION

Doctors are bound to obtain informed written consent prior to any form of surgical procedure on a patient. The General Medical Council (GMC) and the Royal College of Surgeons of England (RCS) provide guidance on what constitutes valid consent. Failure to obtain valid and adequate consent can have legal ramifications. All relevant material risks associated with the surgery must be discussed with the patient during the consenting process.

MATERIALS AND METHODS

This was a retrospective cross-sectional study of the consenting practices for neck of femur fracture surgeries, covering a period of three months, from the 15th of April to the 15th of July 2023. We evaluated the consent forms of 100 patients, of which 63 were consent form-1 and were included in the study. The British Orthopaedics Association (BOA)-endorsed consent forms, together with the RCS and GMC guidance on consent, which were used as the standard for the audit.

RESULTS

The majority of the consents were obtained by senior house officers (SHO) and core surgical trainees who did not have prior formal orthopaedic training (52.4%). The risks that were most frequently documented were infection, blood clots (deep vein thrombosis and pulmonary embolism), and bleeding, with documentation rates of over 90%. Prosthetic joint dislocation following hemiarthroplasty or total hip replacement was not mentioned in 22.2% of the forms. Neurovascular injury was not documented in 20.6% of the consent forms. Less than 75% documentation rates were observed for postoperative pain (74.6%), anesthetic complications (73%), failure (malunion/non-union/loosening of prosthesis) (68.3%), leg length discrepancy (60.3%), bone damage/fracture (50.8%), death (49.2%), wound-related complications/scars (42.9%), and hip stiffness (14.3%). None of the patients had been advised about the probable need for catheterization following surgery. We also noted that 22.2% (n=14) of the consent forms did not contain the diagnosis or the indication for surgery, 12.7% (n=8) did not mention the intended benefits, and 28.6% (n=18) of the consent forms had no mention of the responsible consultant. We also noted that in 25.4% (n=16) of the cases, the possible requirement of a blood transfusion had not been mentioned.

CONCLUSION

The audit revealed several deficiencies in the consenting of patients for neck and femur fracture surgeries. There were poor documentation rates for risks associated with surgery, especially the less common and rare ones. We also identified several deficiencies in the remaining aspects of the consent forms that were not in keeping with the GMC and RCS guidance on consent. The lack of orthopaedic training and knowledge among the senior house officers and core trainees may be a contributing factor.

Disparities in the Epidemiology and Management of Fragility Hip Fractures

PURPOSE OF REVIEW

The purpose of this review is to synthesize the recently published scientific evidence on disparities in epidemiology and management of fragility hip fractures.

RECENT FINDINGS

There have been a number of investigations focusing on the presence of disparities in the epidemiology and management of fragility hip fractures. Race-, sex-, geographic-, socioeconomic-, and comorbidity-based disparities have been the primary focus of these investigations. Comparatively fewer studies have focused on why these disparities may exist and interventions to reduce disparities. There are widespread and profound disparities in the epidemiology and management of fragility hip fractures. More studies are needed to understand why these disparities exist and how they can be addressed.

The impact of chronic kidney disease and dialysis therapy on outcomes of elderly patients with hip fractures: A systematic review and meta-analysis

BACKGROUND AND AIMS

Hip fractures are a commonly occurring comorbidity in patients with chronic kidney disease. To evaluate the comparative rates of post-operative complications, revision surgery, and mortality after hip fracture surgery in chronic kidney disease patients undergoing hemodialysis.

METHODS

A systematic search of the academic literature was performed according to the PRISMA guidelines across five databases: Web of Science, EMBASE, CENTRAL, Scopus, and MEDLINE. A random-effect meta-analysis was conducted to evaluate the overall comparative risks of post-operative complications in chronic kidney disease patients.

RESULTS

Out of 993 studies, 11 eligible studies were included in the review, with a total of 72618 chronic kidney disease patients (mean age: 75.3  ±  3.0 years), and 50566 healthy controls (75.3  ±  2.6 years). Meta-analysis revealed a higher risk of post-operative complications (Odd's ratio: 1.76), revision surgeries (1.69), and mortality-related outcomes (2.47) after hip fracture surgery in chronic kidney disease patients undergoing hemodialysis as compared to chronic kidney disease patients not undergoing hemodialysis.

CONCLUSION

We report higher risks of post-operative complications, revision surgery, and mortality in chronic kidney disease patients undergoing hemodialysis as compared to chronic kidney disease patients not undergoing hemodialysis.

Self-reported physical functional health predicts future bone mineral density in EPIC-Norfolk cohort

Using a large population sample from the UK, we found that self-reported physical functional health may be used to predict future bone mineral density especially in women. It may be a useful and inexpensive way to identify individuals before further decline in bone mineral density and the risk of fracture.

PURPOSE

Self-reported physical functional health may predict bone mineral density (BMD) and thus provide a method to identify people at risk of low BMD. In this study, the association between the 36-item short-form questionnaire (SF-36) physical component summary (PCS) score and future BMD in participants aged 40-79 years enrolled in the European Prospective Investigation of Cancer-Norfolk study was investigated.

METHODS

Associations between a participant's SF-36 PCS score, measured 18 months after baseline health check, and broadband ultrasound attenuation (BUA-a measure of BMD), measured 2-5 years after baseline, were examined using sex-specific linear and logistic regression analyses adjusting for age, BMI, medical co-morbidities, lifestyle and socioeconomic factors.

RESULTS

Data from 10,203 participants, mean (standard deviation (SD)) age 61.5 (8.9) years (57.4% women), were analysed from 1993 to 2000. For every five points lower PCS score in men and women, there was approximately a 0.5 dB/MHz lower mean BUA. In women, a PCS score of less than one standard deviation (1SD) below the sex-specific mean was associated with having a low BUA (< 1SD below sex-specific mean) and very low BUA (< 2.5SD below the sex specific mean); odds ratio (OR) (95% confidence interval) 1.53 (1.24, 1.88) and 8.28 (2.67, 25.69), respectively. The relationship was lesser so in men; corresponding OR (95% CI) were 1.34 (0.91, 1.98) and 2.57 (0.72, 9.20), respectively.

CONCLUSIONS

Self-reported physical functioning predicts BMD in an apparently healthy population, particularly in women. This could potentially provide an inexpensive, simple screening tool to identify individuals at risk of osteoporosis.

Health-related quality of life in men with osteoporosis: a systematic review and meta-analysis

PURPOSE

The increased social and economic burdens make osteoporosis in men an emerging public health issue. However, the quality of life among men with osteoporosis is still unclear. This systematic review and meta-analysis aimed to evaluate the health-related quality of life (HRQoL) among men with osteoporosis or osteoporotic fracture.

METHODS

PubMed, EMBASE, and the Cochrane Library database were systematically searched from inception to May 2021. Studies were included if they used validated questionnaires to measure HRQoL among osteoporotic men. A meta-analysis was performed using a random-effects model or fixed-effects model to calculate the standard mean difference (SMD) or mean difference (MD) with 95% confidential interval (95% CI).

RESULTS

14 studies involving 6338 male participants were chosen for systematic review, of which 10 were included in the meta-analysis. Men with osteoporosis had poorer global HRQoL and multiple dimensions of HRQoL than men without osteoporosis. Hip fracture, vertebral fractures, or wrist fractures dramatically impaired HRQoL of men, and physical function was declined even before hip fracture (SMD = -0.60, 95% CI, -0.82 to -0.39). Femoral and lumbar BMD was positively correlated with HRQoL, and a number of fragility fractures and time since fracture had negative effects on HRQoL. Effective anti-osteoporotic drugs could improve HRQoL of men.

CONCLUSION

The health-related life quality of men was significantly impaired by osteoporosis and fracture of the hip, vertebral, or wrist. We should pay more attention to the diagnosis and treatment of male osteoporosis to improve the life quality of men.

Management of preoperative pain in elderly patients with moderate to severe cognitive deficits and hip fracture: a retrospective, monocentric study in an orthogeriatric unit

Background

Patients with cognitive deficits are 3 times more likely to suffer a hip fracture than geriatric patients of the same age group without cognitive deficits. The persistence of perioperative pain following hip fracture is a risk factor for the occurrence of delirium, poor functional prognosis, and the development of secondary chronic pain. Patients with cognitive deficits receive 20 to 60% less analgesics than those without cognitive deficits. Our retrospective descriptive monocentric study was performed in an orthogeriatric unit on a cohort of elderly patients hospitalized for hip fracture. The aim of the study was to compare the quantity of strong opioids delivered in a morphine sulfate equivalent daily during the preoperative period after a hip fracture between cognitively intact patients and those with cognitive deficits.

Results

Our total population of 69 patients had a median age of 90 years old, and 46% of these patients had moderate or severe cognitive deficits. During the preoperative period, the same quantity of strong opioids was administered to both groups of patients (13.1 mg/d versus 10.8 mg/d (p = 0.38)). Patients with moderate to severe cognitive deficits more often experienced delirium during their hospitalization (p < 0.01) and received more psychotropic drugs in the first 3 postoperative days (p = 0.025).

Conclusions

We reported that with standardized pain management in an orthogeriatric unit, patients aged 75 years and older received the same daily average quantity of strong opioids during the preoperative period regardless of the presence of cognitive deficits.

Recovery of quality of life is associated with lower mortality 5-year post-fracture: the Australian arm of the International Costs and Utilities Related to Osteoporotic Fractures Study (AusICUROS)

Little is known about factors that lead to excess mortality post-fracture. This study demonstrated that 5-year mortality is lower in older adults who recovered to their pre-fracture health-related quality of life (HRQoL) at 12-months compared to those who did not recover. Our results highlight the importance of post-fracture interventions known to improve HRQoL.

INTRODUCTION

Fragility fractures lead to increased mortality and decreased health-related quality of life (HRQoL) in older adults, although whether an association exists between these outcomes remains uncertain. The aim of this study was to determine whether recovery of HRQoL 12-month post-fracture is associated with lower 5-year mortality.

METHODS

This data linkage study included 524 adults (mean age: 70.2 years; 79.2% women) with fragility fracture (150 hip, 261 distal forearm, 61 vertebral, 52 humerus) from the Australian arm of the International Costs and Utilities Related to Osteoporotic fractures Study (AusICUROS). HRQoL was measured using the EQ-5D-3L and all-cause mortality post-fracture was ascertained from the Australian National Death Index (NDI). Cox proportional hazards models were used to assess the association between HRQoL recovery (vs. non-recovery) and all-cause mortality within 5 years.

RESULTS

Overall, 279 participants (53.2%) recovered to their pre-fracture HRQoL at 12-month follow-up. There were 70 deaths (13.4%) during the 5-year post-fracture. Mortality rate was the highest in hip fracture participants (24.7%), followed by vertebral (16.4%), humeral (13.5%), and distal forearm fracture participants (6.1%). After adjustment for age, pre-fracture HRQoL, and fracture site, mortality risk was lower in participants who recovered to their pre-fracture HRQoL at 12-months compared to those who did not recover (HR = 0.56, 95% CI: 0.33-0.96, p = 0.034).

CONCLUSION

This study provides evidence that HRQoL recovery post-fracture is associated with improved 5-year survival in older adults. The extent to whether current interventions known to improve HRQoL post-fracture could prevent some of these deaths is unknown.

Associations between Bone Material Strength Index, Calcaneal Quantitative Ultrasound, and Bone Mineral Density in Men

OBJECTIVES

Impact micro-indentation (IMI) measures bone material strength index (BMSi) in vivo. This study investigated how IMI is associated with calcaneal quantitative ultrasound and bone densitometry parameters in men.

METHODS

BMSi was measured on the tibial plateau using the OsteoProbe in 377 men (age 33-96 years) from the Geelong Osteoporosis Study. Broadband ultrasound attenuation (BUA), speed of sound (SOS), and stiffness index (SI) were assessed at the calcaneus using an ultrasonometer. Areal BMD was measured at several skeletal sites using dual-energy x-ray absorptiometry. Linear associations between parameters were tested using Pearson's correlation. Multivariable regression techniques were used to determine associations between BMSi and other measures of bone, independent of confounders.

RESULTS

BMSi was negatively correlated with age (r = -0.171, P = .001), weight (r = -0.100, P = .052), and body mass index (r = -0.187, P = .001), and positively with height (r = +0.109, P = .034). There was some evidence to support a positive association between BMSi and BUA (β = 0.052, P = .037), SOS (β = 0.013, P = .144), and SI (β = 0.036, P = .051). After age adjustment, this association was attenuated. No correlations were observed between BMSi and BMD at any skeletal site (r values ranged from -0.006 to +0.079, all P ≥ .13).

CONCLUSION

There was a small positive association between BMSi and quantitative ultrasound (QUS) parameters, which were not independent of age. No associations were detected between BMSi and BMD. This suggests that BMSi and QUS are capturing common age-dependent properties of bone. Further research on the utility of IMI alone and complementary to conventional bone testing methods for predicting fracture risk is warranted.

Closing the Osteoporosis Care Gap

PURPOSE OF REVIEW

This review outlines the scope of the problem in osteoporosis care and secondary fracture prevention and describes fracture prevention strategies, with a focus on the frail elderly.

RECENT FINDINGS

Despite heightened awareness among patients and clinicians alike and the availability of efficacious anti-osteoporosis medications, osteoporosis is still underdiagnosed and undertreated. However, the introduction of systematic risk assessment and secondary fracture prevention programmes has gained momentum, and evidence of success is accumulating. We possess today the knowledge required to close the osteoporosis care gap. The basic components in a secondary prevention model are similar in all health care settings, number one being a dedicated fracture coordinator, with anti-osteoporosis medications and multifaceted falls prevention as cornerstones, particularly in the frailest, both in the near and long-term. Initiation of structured care pathways including the key elements - identification, investigation, intervention and follow-up of adherence - demonstrably reduces re-fracture rates and is cost-effective.

One-year mortality rates and factors affecting mortality after surgery for fracture neck of femur in the elderly

Context:

Fractures around hip in elderly are associated with significant morbidity and mortality.

Aim:

This sudy aims to investigate 1-year mortality rates and risk factors associated with this mortality. Effect of delay in surgery on mortality rates will also be studied. Our null-hypothesis was that there is no association between common comorbid conditions or delay in surgery on 1-year mortality rates.

Study Settings and Design:

Patients 60-years and above who underwent operative treatment for fracture of neck of femur between January 2018 and February 2019 were included in this retrospective study.

Materials and Methods:

Demographic and clinical data were collected from hospital information system and inpatient case records. Patients were followed up with quality of life (QoL) assessment with short form-12 (SF-12) at 1 year. Mortality during this period was also evaluated.

Statistical Analysis:

Continuous factors were expressed as means, standard deviations. Different risk factors between the patients alive and dead were studied using Fisher's exact test.

Results:

Nineteen out of 95 patients died at the end of 1 year. Smoking, hypertension, diabetes, low hemoglobin, raised total leukocyte count, low serum albumin, delay in surgery (>1 week), higher American Society of Anesthesiologist grade, and postoperative blood transfusion were significantly associated with higher mortality rates. Mean SF-12 QoL scores at 1 year was 35.6 ± 6.3.

Conclusion:

Hip fractures in elderly are associated with higher mortality rates. Results of this study indicate that patients at a higher risk of mortality may be identified and help in preoperative optimization with the aim to reduce mortality. However, these findings need to be verified by further studies with a relatively larger sample size and longer follow-up period.

Associations Between Bone Impact Microindentation and Clinical Risk Factors for Fracture

Impact microindentation (IMI) measures bone material strength index (BMSi) in vivo. However, clinical risk factors that affect BMSi are largely unknown. This study investigated associations between BMSi and clinical risk factors for fracture in men. BMSi was measured using the OsteoProbe in 357 men (ages 33 to 96 years) from the Geelong Osteoporosis Study. Risk factors included age, weight, height, body mass index (BMI), femoral neck bone mineral density (BMD), parental hip fracture, prior fracture, type 2 diabetes mellitus (T2DM), secondary osteoporosis, smoking, alcohol consumption, sedentary lifestyle, medications, diseases, and low serum vitamin D levels. BMSi was negatively associated with age (r = -0.131, P = 0.014), weight (r = -0.109, P = 0.040), and BMI (r = -0.083, P = 0.001); no correlations were detected with BMD (r = 0.000, P = 0.998) or height (r = 0.087, P = 0.10). Mean BMSi values for men with and without prior fracture were 80.2 ± 6.9 vs 82.8 ± 6.1 (P = 0.024); parental hip fracture, 80.1 ± 6.1 vs 82.8 ± 6.9 (P = 0.029); and T2DM, 80.3 ± 8.5 vs 82.9 ± 6.6 (P = 0.059). BMSi did not differ in the presence vs absence of other risk factors. In multivariable models, mean (± SD) BMSi remained associated with prior fracture and parental hip fracture after adjusting for age and BMI: prior fracture (80.5 ± 1.1 vs 82.8 ± 0.4, P = 0.044); parental fracture (79.9 ± 1.2 vs 82.9 ± 0.4, P = 0.015). No other confounders were identified. We conclude that in men, BMSi discriminates prior fracture and parental hip fracture, which are both known to increase the risk for incident fracture. These findings suggest that IMI may be useful for identifying men who have an increased risk for fracture.

Examining Differences in Recovery Outcomes between Male and Female Hip Fracture Patients: Design and Baseline Results of a Prospective Cohort Study from the Baltimore Hip Studies

BACKGROUND

Incidence of hip fractures in men is expected to increase, yet little is known about consequences of hip fracture in men compared to women. It is important to investigate differences at time of fracture using the newest technologies and methodology regarding metabolic, physiologic, neuromuscular, functional, and clinical outcomes, with attention to design issues for recruiting frail older adults across numerous settings.

OBJECTIVES

To determine whether at least moderately-sized sex differences exist across several key outcomes after a hip fracture.

DESIGN, SETTING, AND PARTICIPANTS

This prospective cohort study (Baltimore Hip Studies 7th cohort [BHS-7]) was designed to include equal numbers of male and female hip fracture patients to assess sex differences across various outcomes post-hip fracture. Participants were recruited from eight hospitals in the Baltimore metropolitan area within 15 days of admission and were assessed at baseline, 2, 6 and 12 months post-admission.

MEASUREMENTS

Assessments included questionnaire, functional performance evaluation, cognitive testing, measures of body composition, and phlebotomy.

RESULTS

Of 1709 hip fracture patients screened from May 2006 through June 2011, 917 (54%) were eligible and 39% (n=362) provided informed consent. The final analytic sample was 339 (168 men and 171 women). At time of fracture, men were sicker (mean Charlson score= 2.4 vs. 1.6; p<0.001) and had worse cognition (3MS score= 82.3 vs. 86.2; p<0.05), and prior to fracture were less likely to be on bisphosphonates (8% vs. 39%; p<0.001) and less physically active (2426 kilocalories/week vs. 3625; p<0.001).

CONCLUSIONS

This paper provides the study design and methodology for recruiting and assessing hip fracture patients and evidence of baseline and pre-injury sex differences which may affect eventual recovery one year later.

Distal Forearm Bone Mineral Density Among Hill Tribes in the Omkoi District, Chiang Mai Province, Thailand

Background:

Osteoporosis is a major public health issue in several countries worldwide because it increases healthcare costs, and is a risk for mortality. There have been several studies that have examined BMD among the various Thai people and the regions that they inhabit.

Objective:

This study examined the distal forearm Bone Mineral Density (BMD) in men and women over 40 years of age among members of various Karen hill-tribes located in the Omkoi District, Chiang Mai Province, Thailand.

Methods:

Two hundred and sixty-two subjects (180 women, 82 men), ranging from 40 to 83 years old were recruited in this study. The non-dominant distal forearm bone mineral density was assessed by using peripheral dual-energy X-ray absorptiometry (pDEXA).

Results:

The results showed that the BMD were 0.530 ± 0.065, 0.508 ± 0.087, 0.461 ± 0.098, and 0.438 ± 0.124 g/cm2for men age 40-49 years, age 50-59 years, age 60-69 years, and ages 70-83 years, respectively. For women, the BMD were 0.392 ± 0.051, 0.337 ± 0.063, 0.232 ± 0.065, and 0.212 ± 0.069 g/cm2among women age 40-49 years, age 50-59 years, age 60-69 years, and ages 70-83 years, respectively. BMD had decreased in post-menopause as a function of duration time after menopause.

Conclusion:

We determined the prevalence of osteoporosis of men and women of Karen hill-tribes in the Chiang Mai Province, Thailand. These findings provided important information regarding bone health in Karen hill-tribes for any healthcare planning done in the immediate future.

Predictors of In-Hospital Ambulatory Status Following Low-Energy Hip Fracture Surgery

Introduction:

Twenty-five percent to seventy-five percent of independent patients do not walk independently after hip fracture (HF), and many patients experience functional loss. Early rehabilitation of functional status is associated with better long-term outcomes; however, predictors of early ambulation after HF have not been well described.

Purposes:

To assess the impact of perioperative and patient-specific variables on in-hospital ambulatory status following low-energy HF surgery.

Methods:

This is a retrospective analysis of 463 geriatric patients who required HF surgery at a metropolitan level-1 trauma center. The outcomes were time to transfer (out of bed to chair) and time to walk.

Results:

Three hundred ninety-two (84.7%) patients were able to transfer after surgery with a median time of 43.8 hours (quartile range: 24.7-53.69 hours), while 244 (52.7%) patients were able to walk with a median time of 50.86 hours (quartile range: 40.72-74.56 hours). Preinjury ambulators with aids (hazard ratio [HR]: 0.70, confidence interval [CI]: 0.50-0.99), age >80 years (HR: 0.66, CI: 0.52-0.84), peptic ulcer disease (HR: 0.57, CI: 0.57-0.82), depression (HR: 0.66, CI: 0.49- 0.89), time to surgery >24 hours (HR: 0.77, CI: 0.61-0.98), and surgery on Friday (HR: 0.73, CI: 0.56-0.95) were associated with delayed time to transfer. Delayed time to walk was observed in patients over 80 years old (HR: 0.74, CI: 0.56-0.98), females (HR: 0.67, CI: 0.48-0.94), peptic ulcer disease (HR: 0.23, CI: 0.84-0.66), and depression (HR: 0.51, CI: 0.33-0.77).

Conclusions:

Operative predictors of delayed time to transfer were surgery on Friday and time to surgery >24 hours after admission. Depression is associated with delayed time to transfer and time to walk. These data suggest that is important to perform surgeries within 24 hours of admission identify deficiencies in care during the weekends, and create rehabilitation programs specific for patient with depression. Improving functional rehabilitation after surgery may facilitate faster patient discharge, decrease inpatient care costs, and better long-term functional outcomes.

Prior fracture and refracture among patients admitted with hip fracture: Data from a regional hip fracture registry in Sri Lanka

AIM

Fragility hip fracture has become a major global health concern. Data related to recurrent fragility fractures are sparse in the South Asian region.

METHOD

We assessed the prevalence of prior fragility fracture among patients admitted with new hip fracture to a tertiary care hospital in southern Sri Lanka. Also the incidence of refracture was assessed among hip fracture survivors followed up for 24 months after discharge.

RESULTS

Three hundred and nine patients with incident hip fracture were admitted during the study period (June 2014-February 2015) and 11 patients died while in the ward. We detected previous fracture in the contralateral hip in eight patients, while two others had distal radius fracture and one patient clinical vertebral fracture (rate = 3.6%). During the follow up two patients developed fractures in the contralateral hip while either clinical vertebral or distal forearm fractures were not detected (refracture rate = 0.004/person years).

CONCLUSION

This analysis based on a regional hip fracture registry shows a low prevalence of prior fracture among patients admitted with incident hip fracture and a low rate of refracture among survivors. More studies are needed to assess whether there are geographical variations in the prevalence of prior fracture or refracture among patients with incident hip fracture.

The Intersection of Medicine and Urology: An Emerging Paradigm of Sexual Function, Cardiometabolic Risk, Bone Health, and Men's Health Centers

Men's mental health and how they think about their health are critical to the future of men's health. Poor health choice patterns are established under age 50, when men are twice as likely to die than women. As the future of medicine focuses on quality and value, a better understanding of the social determinants of men's health will identify areas for improvement. The presentation of a man to a clinician's office with a sexual health complaint presents an opportunity for more complete evaluation. The future of men's health will be well served by integrated men's health centers that focus on the entire man.

Quality of life and psychological consequences in elderly patients after a hip fracture: a review

Fractures due to fragility of the bone around the hip joint have become a major public health issue, presenting with an increasing incidence due to the growth of the elderly population. The purpose of this review was to evaluate the impact of hip fractures on the quality of life (QoL), health status (HS), functioning, and psychological parameters, and factors influencing the outcome and the appropriate interventions for improvement of elderly patients. A systematic electronic search of the relevant literature was carried out using the CINAHL, Cochrane, EMBASE, Medline (OvidSP), and PubMed databases spanning the time period from their establishment up to January 2017. Forty-nine randomized controlled trials or prospective cohort studies reporting the QoL and psychological outcomes were assessed by using standardized questionnaires. Patients with a hip fracture who were older than 65 years, were included in the analysis. In the majority of elderly patients, the hip fracture seriously affected physical and mental functioning and exerted a severe impact on their HS and health-related QoL (HRQoL). Moreover, most of the patients did not return to prefracture levels of performance regarding both the parameters. The levels of mental, physical, and nutritional status, prior to the fracture, comorbidity, and female gender, in addition to the postoperative pain, complications, and the length of hospital stay, were the factors associated with the outcome. Psychosocial factors and symptoms of depression could increase pain severity and emotional distress. For the displaced femoral neck fractures, the treatment with total hip arthroplasty or hemiarthroplasty, when compared to the treatment with internal fixation, provided a better functional outcome. Supportive rehabilitation programs, complemented by psychotherapy and nutritional supplementation prior to and after surgery, provided beneficial effects on the HS and the psychosocial dimension of the more debilitated patients’ lives. Lack of consensus concerning the most appropriate HRQoL questionnaires to screen and identify those patients with more difficulties in the psychosocial functions, demonstrates the necessity for further research to assess the newer outcome measurement tools, which might improve our understanding for better care of patients with hip fractures.

Bone mineral density at distal forearm in men over 40 years of age in Mae Chaem district, Chiang Mai Province, Thailand: a pilot study

OBJECTIVE

To study the prevalence of bone mineral density (BMD) and osteoporosis in the distal forearm among Thai men over 40 years of age in Mae Chaem District, Chiang Mai Province, Thailand.

METHODS

The subjects in this study were 194 Thai men, aged between 40 and 87 years who resided in Mae Chaem District, Chiang Mai Province, Thailand. Self-administered questionnaires were used for receiving the demographic characteristics information. BMD was measured by peripheral dual energy X-ray absorptiometry at the nondominant distal forearm in all men.

RESULTS

The BMD was highest in the age-group 40-49 years and lowest in the age-group 70-87 years. The average T-score at the distal forearm was also highest in the age-group 40-49 years and lowest in the age-group 70-87 years. The BMD decreased as a function of age-group (p < .05). In contrast, the BMD increased as a function of weight (p < .05). Height had weak impact on the BMD in the distal forearm (p > .05). The percentage of osteopenia and osteoporosis are increased as a function of age-group in, while decreased in that of normal bone density.

CONCLUSIONS

We found the prevalence of osteoporosis in men who resided in Mae Chaem District, Chiang Mai Province, Thailand.

Predictors of non-vertebral fracture in older Chinese males and females: Mr. OS and Ms. OS (Hong Kong)

Clinical risk factors to predict fracture are useful in guiding management of patients with osteoporosis or falls. Clinical predictors may however be population specific because of differences in lifestyle, environment and ethnicity. Four thousand community-dwelling Chinese males and females with average ages of 72.4 and 72.6 years were followed up for incident fractures, with an average of 6.5 and 8.8 years, respectively. Clinical information was collected, and bone mineral density (BMD) measurements were carried out at baseline. Stepwise Cox regression models were used to identify risk factors of nonvertebral fractures, with BMD as covariate. Areas under the receiver-operating characteristic (ROC) curve (AUC) were compared among different risk models. The incidence rates of nonvertebral fractures were 10.3 and 20.5 per 1000 person years in males and females, respectively. In males, age ≥80, history of a fall in the past year, fracture history, chronic obstructive pulmonary disease, impaired visual depth perception and low physical health-related quality of life were significant fracture risk factors, independent of BMD. In females, the significant factors were fracture history, low visual acuity and slow narrow walking speed. The clinical risk factors had a significant influence on fracture risk irrespective of osteoporosis status, even having a better risk discrimination than BMD alone, especially in males. The best risk prediction model consisted both BMD and clinical risk factors. Clinical risk factors have additive value to hip BMD in predicting nonvertebral fractures in older Chinese people and may predict them better than BMD alone in older Chinese males.

Receipt of Caregiving and Fall Risk in US Community-dwelling Older Adults

BACKGROUND

Falls and fall-related injuries (FRI) are common and costly occurrences among older adults living in the community, with increased risk for those with physical and cognitive limitations. Caregivers provide support for older adults with physical functioning limitations, which are associated with fall risk.

DESIGN

Using the 2004-2012 waves of the Health and Retirement Study, we examined whether receipt of low (0-13 weekly hours) and high levels (≥14 weekly hours) of informal care or any formal care is associated with lower risk of falls and FRIs among community-dwelling older adults. We additionally tested whether serious physical functioning (≥3 activities of daily living) or cognitive limitations moderated this relationship.

RESULTS

Caregiving receipt categories were jointly significant in predicting noninjurious falls (P=0.03) but not FRIs (P=0.30). High levels of informal care category (P=0.001) and formal care (P<0.001) had stronger associations with reduced fall risk relative to low levels of informal care. Among individuals with ≥3 activities of daily living, fall risks were reduced by 21% for those receiving high levels of informal care; additionally, FRIs were reduced by 42% and 58% for those receiving high levels of informal care and any formal care. High levels of informal care receipt were also associated with a 54% FRI risk reduction among the cognitively impaired.

CONCLUSIONS

Fall risk reductions among older adults occurred predominantly among those with significant physical and cognitive limitations. Accordingly, policy efforts involving fall prevention should target populations with increased physical functioning and cognitive limitations. They should also reduce financial barriers to informal and formal caregiving.

Hip fracture, mortality risk, and cause of death over two decades

Men and women with hip fracture have higher short-term mortality. This study investigated mortality risk over two decades post-fracture; excess mortality remained high in women up to 10 years and in men up to 20 years. Cardiovascular disease (CVD) and pneumonia were leading causes of death with a long-term doubling of risk.

INTRODUCTION

Hip fractures are associated with increased mortality, particularly short term. In this study with a two-decade follow-up, we examined mortality and cause of death compared to the background population.

METHODS

We followed 1013 hip fracture patients and 2026 matched community controls for 22 years. Mortality, excess mortality, and cause of death were analyzed and stratified for age and sex. Hazard ratio (HR) was estimated by Cox regression. A competing risk model was fitted to estimate HR for common causes of death (CVD, cancer, pneumonia) in the short and long term (>1 year).

RESULTS

For both sexes and at all ages, mortality was higher in hip fracture patients across the observation period with men losing most life years (p < 0.001). Mortality risk was higher for up to 15 years (women (risk ratio (RR) 1.9 [95 % confidence interval (CI) 1.7-2.1]); men (RR 2.8 [2.2-3.5])) and until end of follow-up ((RR 1.8 [1.6-2.0]); (RR 2.7 [2.1-3.3])). Excess mortality by time intervals, censored for the first year, was evident in women (<80 years, up to 10 years; >80 years, for 5 years) and in men <80 years throughout. CVD and pneumonia were predominant causes of death in men and women with an associated higher risk in all age groups. Pneumonia caused excess mortality in men over the entire observation period.

CONCLUSION

In a remaining lifetime perspective, all-cause and excess mortality after hip fracture was higher even over two decades of follow-up. CVD and pneumonia reduce life expectancy for the remaining lifetime and highlights the need to further improve post-fracture management.

Factors associated with the course of health-related quality of life after a hip fracture

INTRODUCTION

The number of hip fracture patients is expected to grow the forthcoming decades. Knowledge of the impact of the fracture on the lives of elderly could help us target our care. The aim of the study is to describe HRQoL (Health-Related Quality of Life) after a hip fracture and to identify factors associated with the course of HRQoL in the first postoperative year.

MATERIALS AND METHODS

335 surgically treated hip fracture patients (mean age 79.4 years, SD 10.7, 68 % female) were included in a prospective observational cohort. HRQoL was measured with the SF-12 Health Survey, composed of the Physical and a Mental Component Summary Score (PCS, MCS), at admission (baseline) and at 3 and 12 months postoperatively. Eleven predefined factors known to be associated with the course of HRQoL were recorded: age, gender, physical status, having a partner at admission, living in an institution, prefracture level of mobility, anemia, type of fracture and treatment, delirium during hospital stay and length of stay.

RESULTS

HRQoL declined between baseline and 3 months, and recovered between three and 12 months. PCS HRQoL did not recover to baseline values, MCS HRQoL did. Age younger than 80 years, ASA classification I and II, higher prefracture level of mobility, intracapsular fracture and treatment with osteosynthesis (compared to arthroplasty) were associated with greater initial decline in PCS HRQoL, none of the recorded factors were significant for decline in MCS HRQoL.

CONCLUSIONS

Both PCS and MCS HRQoL declined after a hip fracture and PCS did not recover to baseline values. Healthier patients may need extra care to prevent them from having a steep decline in postoperative PCS HRQoL and arthroplasty should be considered with low threshold.

Can orthopedic surgeons help create a better head start for osteoporosis treatment after hip fracture?

BACKGROUND

Treatment for osteoporosis in the community in patients who were operated for hip fracture appears to be suboptimal at best. Evidence regarding treatment beyond the 1st year after surgery is scarce. We examined the association between discharge recommendations for treatment of osteoporosis in patients suffering from hip fractures and treatment beyond the 1st year.

METHODS AND MATERIALS

We performed a retrospective observational cohort study in patients age 50 to 90 years operated for osteoporotic hip fractures between the years 2008 and 2014. We investigated the correlation between discharge recommendations and rates of osteoporosis treatment postdischarge 1 to 7 years, and the influence of osteoporosis diagnosis upon treatment. Exclusion criteria besides age included high-energy trauma, pathologic or periprosthetic fractures, and patients deceased within 1-year postsurgery.

RESULTS

A total of 602 patient files were examined. Univariate analysis showed that, of 283 patients who were prescribed dietary supplementation of vitamin D and calcium, a significantly higher percentage of patients received treatment if they had a recommendation (50.3% vs 36.1%, P = 0.0005), were diagnosed (43.8% vs 14.4%, P < 0.0001), or were of female gender (84.1% vs 57.3%, P < 0.0001). Multivariate analysis showed that the odds ratio (OR) for receiving treatment compared with the control group (patients without a recommendation and a diagnosis) was higher among patients who had both a recommendation and a treatment (OR = 5.4, P < 0.0001) than the group with a diagnosis only (OR = 4.75, P < 0.0001) or a recommendation only (OR = 2.06, P = 0.0006).

CONCLUSIONS

A formal recommendation for osteoporosis treatment in the discharge letters of patients who suffered hip fragility fractures increases treatment rate of osteoporosis in the community compared with patients without a recommendation. Patients who receive such a recommendation but also have a formal coded diagnosis of osteoporosis in their medical files have an even higher chance of receiving treatment in the community. Our observations may assist in amplifying the overall treatment rates, which are still undoubtedly low.

Bone Mineral Density in Navajo Men and Women and Comparison to Non-Hispanic Whites from NHANES (2005-2008)

PURPOSE

To describe bone mineral density (BMD) at the hip and spine and prevalence of low bone mass and osteoporosis in Navajo men and women across age, gender, and body mass index (BMI) compared with non-Hispanic (NH) Whites from NHANES (2005-2008).

METHODS

Cross-sectional dual energy x-ray absorptiometry measurements at the hip and spine in 1,097 participants from the Education and Research Towards Health study.

RESULTS

Bone mineral density was lower among younger Navajo than NH-Whites at lower BMI, and in overweight, younger men at lumbar spine and total hip. Spine BMD was lower in Navajo women, across BMI. Prevalence of low bone mass and osteoporosis in Navajo was higher than NH-Whites, particularly among women.

CONCLUSIONS

Further research is needed to understand if lower BMD among younger Navajo signals a risk for future fracture, and fracture risk relative to BMD, given the challenges in health care access and fracture morbidity among minorities.

Bisphosphonates can prevent recurrent hip fracture and reduce the mortality in osteoporotic patient with hip fracture: A meta-analysis

Objective:

This meta-analysis was conducted to investigate the efficacy of bisphosphonates for preventing recurrent hip fracture and reducing the mortality of elderly patient with hip fracture.

Methods:

The databases of Pubmed, Embase and Cochrane Library were searched. All randomized or prospective matched controlled trials that assessed the efficacy of bisphosphonate for elderly patients with hip fracture were included. Two researchers independently extracted data of the included articles and assessed the methodological quality which was assessed based on Jadad scoring system or Newcastle-Ottawa scale. The second hip fracture incidence, mortality and complications were compared between bisphosphonates and control groups.

Results:

Four studies including 3088 patients were included. Results showed that there were significant difference of second hip fracture (P<0.05) and mortality (P<0.05) between bisphosphonates group and control group. While no significant intergroup difference were observed for all complications.

Conclusions:

Bisphosphonates can prevent subsequent hip fracture, reduce the mortality, and does not increase the overall complications in elderly patients with hip fracture.

[Male osteoporosis]

BACKGROUND

Osteoporosis in men is an important public health problem with more than 1 million cases in Germany. Although osteoporotic fractures have a much higher mortality in men than in women, male patients are still underdiagnosed and undertreated.

OBJECTIVE

Epidemiology of male osteoporosis and current treatment situation, pathophysiological aspects at the hormonal level, risk factors, diagnostic work-up and therapeutic options.

MATERIAL AND METHODS

Overview of data concerning male osteoporosis, recommendations for diagnostic work-up and presentation of the study situation on pharmaceutical therapies.

RESULTS

As risk factors for osteoporosis are present in 50-70 % of male patients, a detailed patient history is necessary for assessment of the risk factors. Radiological imaging of the spine is primarily recommended to identify individuals with prevalent vertebral fractures, as approximately 10 % of males above the age of 50 years have suffered a vertebral fracture. Laboratory testing of relevant parameters helps to rule out other metabolic bone diseases. In Germany, specific medications available for the treatment of male osteoporosis comprise the active vitamin D analogue alfacalcidol, the oral bisphosphonates alendronate and risedronate, the intravenous biphosphonate zoledronic acid, the anti- receptor activator of NF-κB ligand (RANKL) antibody denosumab, which can be given as intravenous injection and strontium ranelate, a drug with a complex mode of action. Teriparatide, a recombinant form of the 34 N-terminal amino acid sequence of parathyroid hormone is the only anabolic agent approved for male osteoporosis.

CONCLUSION

Osteoporosis in men is increasingly being recognized as an important public health problem and affected patients need to be adequately diagnosed and treated. Nowadays, a broad spectrum of well-proven therapeutic options with different modes of action allow individual treatment strategies for male osteoporosis patients.

Age-related changes in the fracture resistance of male Fischer F344 rat bone

In addition to the loss in bone volume that occurs with age, there is a decline in material properties. To test new therapies or diagnostic tools that target such properties as material strength and toughness, a pre-clinical model of aging would be useful in which changes in bone are similar to those that occur with aging in humans. Toward that end, we hypothesized that similar to human bone, the estimated toughness and material strength of cortical bone at the apparent-level decreases with age in the male Fischer F344 rat. In addition, we tested whether the known decline in trabecular architecture in rats translated to an age-related decrease in vertebra (VB) strength and whether non-X-ray techniques could quantify tissue changes at micron and sub-micron length scales. Bones were harvested from 6-, 12-, and 24-month (mo.) old rats (n=12 per age). Despite a loss in trabecular bone with age, VB compressive strength was similar among the age groups. Similarly, whole-bone strength (peak force) in bending was maintained (femur) or increased (radius) with aging. There was though an age-related decrease in post-yield toughness (radius) and bending strength (femur). The ability to resist crack initiation was actually higher for the 12-mo. and 24-mo. than for 6-mo. rats (notch femur), but the estimated work to propagate the crack was less for the aged bone. For the femur diaphysis region, porosity increased while bound water decreased with age. For the radius diaphysis, there was an age-related increase in non-enzymatic and mature enzymatic collagen crosslinks. Raman spectroscopy analysis of embedded cross-sections of the tibia mid-shaft detected an increase in carbonate subsitution with advanced aging for both inner and outer tissue.

High prevalence of secondary factors for bone fragility in patients with a recent fracture independently of BMD

In this study, we demonstrate a high prevalence of secondary factors in patients with a recent fracture independently of bone mineral density (BMD). Our results suggest that patients with a recent fracture should be screened for secondary factors for bone fragility regardless of BMD values.

INTRODUCTION

Secondary factors for bone fragility are common in patients with osteoporosis who have sustained a fracture. The majority of fragility fractures occurs, however, in patients with osteopenia, and it is not known whether secondary factors may contribute to fracture risk in these patients or in those with normal BMD.

METHODS

Prospective cohort study evaluating the prevalence of secondary factors for bone fragility in consecutive patients referred to our fracture liaison service from June 2012 to June 2014 after a recent fracture.

RESULTS

Seven hundred nine patients were included, 201 (28 %) with osteoporosis, 391 (55 %) with osteopenia and 117 (17 %) with normal BMD. Mean age was 66.0 ± 9.8 years, 504 (73 %) were women and 390 (57 %) had one or more underlying secondary factor. Evaluation of clinical risk factors using fracture risk assessment tool (FRAX) identified 38 % of patients with ≥1 secondary factor including smoking (18 %), excessive alcohol use (12 %), glucocorticoid use (12 %) and rheumatoid arthritis (3 %). Laboratory investigations revealed chronic kidney disease in 13 %, monoclonal gammopathy also in 13 % and primary or secondary hyperparathyroidism in 1 and 6 %, respectively. Secondary factors for bone fragility were equally prevalent in patients with osteoporosis, osteopenia or normal BMD.

CONCLUSIONS

Our findings demonstrate a high prevalence of secondary factors for bone fragility in patients who have sustained a recent fracture, independently of BMD. The significant number of documented factors, which were treatable, suggest that patients who sustained a fracture should be screened for secondary factors for bone fragility regardless of BMD values to optimise secondary fracture prevention.

Walking ability before and after a hip fracture in elderly predict greater long-term survivorship

AIM

The morbidity and mortality after a hip fracture in the elderly population are multifactorial. The aim of this study is to determine the long-term impact of specific factors to mortality rate and mobility after a hip fracture in the elderly.

MATERIALS AND METHODS

Elderly suffering a hip fracture after a low-energy trauma was included in the study, whereas moribund patients with severe comorbid conditions and high-energy trauma were excluded. All the patients were treated operatively during 2003. Data for survivorship and mobilization was collected six months, one and ten years after the operation. Kaplan-Meier log rang test was used for the survival analysis and cox regression for multivariate analysis of prediction factors such as age, gender, time to surgery after trauma, type of fracture, ambulation status before injury and early walking ability after the surgery.

RESULTS

Two hundred and thirty three patients were finally included to the study. Gender (p = 0.64) and type of fracture (p = 0.92) seem to have no statistically significant impact on survivorship. Age (p < 0.001), time of surgery after the trauma (p = 0.001), ambulation status (p < 0.001) and early walking ability after the surgery (p < 0.001) seem to have statistically significant impact on mortality, as independent factors. The significance is present one year and ten years after the surgery. However, according to the multivariate analysis, time to surgery after trauma and age lose significance, while early walking ability remain significant one and ten years after surgery (p < 0.001). Ambulation status seem to lose significance early after surgery, but reach significance ten years postoperatively (p < 0.001).

CONCLUSION

In summary, it could be stated that early walking ability after an operation for a hip fracture in elderly is the most significant prediction factor of survivorship one and ten years postoperatively. Ambulation status before injury is a significant long-term predictor factor for survivorship.

Male Osteoporosis in the Elderly

Osteoporosis is now recognized as an important public health problem in elderly men as fragility fractures are complicated by increased morbidity, mortality, and social costs. This review comprises an overview of recent findings in pathophysiology, diagnosis, and treatment of male osteoporosis, with particular regard to the old population.

Comparing Survival Following Hip Fracture Repair in VHA and Non-VHA Facilities

INTRODUCTION

Although postsurgical outcomes are similar between Veterans Health Administration (VHA) and non-VHA hospitals for many procedures, no studies have compared 30-day and 1-year survival following hip fracture repair. Therefore, this study compared survival of veterans aged 65 years and older treated in VHA hospitals with a propensity-matched cohort of Medicare beneficiaries in non-VHA hospitals.

MATERIALS AND METHODS

Retrospective cohort study of 1894 hip fracture repair patients in VHA or non-VHA hospitals between 2003 and 2005. Current Procedural Terminology codes identified 3542 male patients aged >65 years who had hip fracture repair between 2003 and 2005 in the Veterans Affairs' National Surgical Quality Improvement Program database. The Medicare comparison sample was drawn from 2003 to 2005 Medicare Part A inpatient hospital claims files. To create comparable VHA and Medicare cohorts, patients were propensity score matched on age, admission source (community vs. nursing home), repair type, comorbidity index, race, year, and region. Thirty-day and 1-year survival after surgery were compared between cohorts after further adjustment for selected comorbidities, year of surgery, and pre- and postsurgical length of hospital stay using logistic regression.

RESULTS

Odds of survival were significantly better in the Medicare than the VHA cohort at 30 days (1.68, 95% CI 1.15-2.44) and 1 year (1.35, 95% CI 1.08-1.69).

CONCLUSION

Medicare beneficiaries with hip fracture repair in non-VHA hospitals had better survival than veterans in VHA hospitals. Whether this is driven by unobserved patient characteristics or systematic care differences is unknown.

Changes in health-related quality of life and activities of daily living after hip fracture because of a fall in elderly patients: a prospective cohort study

BACKGROUND

The impact of hip fracture because of a fall on health-related quality of life (HRQoL) and activities of daily living (ADL) have not been well established.

AIM

To evaluate changes in HRQoL and the ability to conduct ADL among patients with hip fracture because of a fall and to compare these changes with patients who did not fall and break a hip, adjusting by gender and age.

METHODS

Adults aged 65 or more who attended the emergency departments of seven public hospitals were recruited in a prospective double-cohort study (fracture cohort, n = 776; non-fracture cohort, n = 115). ADL and HRQoL were assessed at baseline (during the postfall hospitalisation or by telephone afterwards) and 6 months later using the Barthel Index and the Lawton Brody Index for ADL, and the Short Form Health Survey (SF-12) and Western Ontario and McMaster Universities Osteoarthritis Index short form (WOMAC-SF) for HRQoL.

RESULTS

Adjusting by gender, age and baseline status, a hip fracture was a strong predictor of decline in all outcomes measured except for mental quality of life among men (measured by SF-12). Hip fracture patients younger than 74 years reported significantly more pain (measured by WOMAC-SF) than the comparison group (p = 0.02), but this difference was not observed among older patients (p = 0.19 for 75-84 years; p = 0.39 for ≥ 85 years).

DISCUSSION

Hip fractures have profound effects on HRQoL and ADL in both men and women, regardless of age. This indicates the need for special follow-up care of elderly hip fracture patients in the immediate and late postfracture periods.

Fracture mortality: associations with epidemiology and osteoporosis treatment

The rates of incident osteoporotic fractures seem to be stabilizing; however, fragility fractures are still associated with considerable disability, costs and an increased risk of mortality, which is particularly the case for fractures of the hip and vertebra. Mortality is usually highest during the first year after fracture; however, a notably increased mortality risk might persist for several years after the event. In addition to its efficacy in the prevention of new and recurrent osteoporotic fractures, medical treatment has been associated with improved survival after osteoporotic fractures. Observational studies and randomized controlled clinical trials have reported increased survival in patients with a fracture who are treated with bisphosphonates. Rates of medical treatment in patients with osteoporosis remain low, and although the rationale for the putative increase in survival is unclear, this emerging evidence might help further justify the use of medical treatment after fracture. However, further work is needed before medical therapy for mortality prevention in patients with osteoporotic fractures is accepted.

Bisphosphonates for treatment of osteoporosis: expected benefits, potential harms, and drug holidays

OBJECTIVE

To outline the efficacy and risks of bisphosphonate therapy for the management of osteoporosis and describe which patients might be eligible for bisphosphonate "drug holiday."

QUALITY OF EVIDENCE

MEDLINE (PubMed, through December 31, 2012) was used to identify relevant publications for inclusion. Most of the evidence cited is level II evidence (non-randomized, cohort, and other comparisons trials).

MAIN MESSAGE

The antifracture efficacy of approved first-line bisphosphonates has been proven in randomized controlled clinical trials. However, with more extensive and prolonged clinical use of bisphosphonates, associations have been reported between their administration and the occurrence of rare, but serious, adverse events. Osteonecrosis of the jaw and atypical subtrochanteric and diaphyseal femur fractures might be related to the use of bisphosphonates in osteoporosis, but they are exceedingly rare and they often occur with other comorbidities or concomitant medication use. Drug holidays should only be considered in low-risk patients and in select patients at moderate risk of fracture after 3 to 5 years of therapy.

CONCLUSION

When bisphosphonates are prescribed to patients at high risk of fracture, their antifracture benefits considerably outweigh their potential for harm. For patients taking bisphosphonates for 3 to 5 years, reassess the need for ongoing therapy.

Quality-of-Life among Elderly with Untreated Fracture of Neck of Femur: A Community Based Study from Southern India

BACKGROUND AND OBJECTIVES

Owing to the high prevalence of osteoporosis and falls, elderly people are at risk of developing hip fractures. The objective of the current study is to assess the quality-of-life (QOL) of elderly (>60 years) with untreated hip fractures in a rural developmental block in Southern India.

METHODOLOGY

Twenty-one elderly with an untreated fracture neck of femur were identified with the help of community level health workers. EuroQol (EQ-5D) was administered to assess the QOL before and after the event. QOL was also assessed among a comparison group, matched for age and sex among neighborhood people. Wilcoxon signed rank test and Mann-Whitney U test were used to compare EQ-5D mean scores with before the event scores and the comparison group scores respectively.

RESULTS

Of people with hip fracture, 57.1% (12/21), 76.2% (16/21), 81% (17/21), 52.6% (11/21) and 85.7% (18/21) reported severe problems with mobility, pain, usual activity, self-care and anxiety respectively. The EQ-5D mean score among the elderly with fracture neck of the femur was 0.08 (SD 0.27). It was low when compared with the same subjects before the occurrence of the event (Z -4.05, P < 0.001) and as compared with the comparison group (Z -5.77 P < 0.001).

CONCLUSION

The QOL scores assessed using EQ-5D index scores was poor among people with untreated fracture neck of the femur as compared with the comparison group and also as compared to their status before the occurrence of the event. A vast majority of study participants reported severe problems with mobility, pain, usual activity and self-care and anxiety domains of EQ-5D questionnaire.

[Effectiveness of co-management between orthopaedic surgeons and internists for inpatient elders with hip fracture]

BACKGROUND AND OBJECTIVE

Hip fracture is a common injury in elder patients who have comorbidities, and it increases the risk of morbimortality. They could benefit from co-management (CM) between orthopaedic surgeons and internists. The objective was to evaluate the effectiveness of this CM.

PATIENTS AND METHOD

Prospective study of 138 patients over 64 years with hip fracture treated with CM care and one-year of follow-up. The control group was a cohort of 153 patients with similar criteria who had been treated with conventional care. Several pre- and postsurgical variables, complications, and potential risk factors for mortality were analyzed. The Charlson index, mental test, Katz and SF-12 quality of life questionnaires, and Merle D'Aubigné hip score were used.

RESULTS

Surgical delay was lower in the CM cohort (P=.001). The rates of complications and readmissions were similar in both cohorts. The average stay was lower (P=.001) in the CM cohort. In-hospital and 3-month mortality were similar, but it was lower in the CM cohort at 6 (P=.04) and 12 months (P=.03). In both cohorts, gender, number of comorbidities, ASA score, Charlson index or surgery type were not predictors of mortality. Surgical delay>2 days was a predictor in the CM cohort, whereas age was a predictor in the control cohort. The final functional outcomes were similar in both cohorts.

CONCLUSION

Our results show the effectiveness of this CM to reduce surgical delay, hospital stay and mortality at 6 months.

Adherence to osteoporosis regimens among men and analysis of risk factors of poor compliance: a 2-year analytical review

BACKGROUND

To investigate adherence and patient-specific factors associated with poor compliance with osteoporosis regimens among men.

METHODS

In this retrospective chart review study, we collected data on male patients with osteoporosis treated in accordance with therapeutic recommendations. Adherence was determined by the compliance and persistence of those patients who had been dispensed an osteoporosis regimen after an index prescription. All osteoporosis regimens were considered equivalent for the purpose of investigating adherence.

RESULTS

The prescriptions of 333 males met the inclusion criteria for data collection. The mean age was 68.6 ± 10.4 years. The median medication possession ratio (MPR, %) at years 1 and 2 was 90.1% (interquartile range (IQR) 19-100) and 53.7% (IQR 10.4-100), respectively; 52.3% of male patients at year 1 and 37.5% at year 2 had good compliance (defined as a MPR≧80%). The 1- and 2-year persistence rates were 45.9% and 30.0%, respectively. Patient-specific factors associated with poor compliance (MPR < 80%) during year 1 were first prescriptions given by orthopedists (odds ratio (OR) = 2.67; 95% confidence interval (CI) = 1.58-4.53; adjusted OR = 2.30, 95% CI = 1.26-4.22, p = 0.007). Male patients with rheumatoid arthritis (RA) (OR = 0.22, 95% CI = 0.06-0.78, adjusted OR = 0.19, 95% CI = 0.04-0.81, p = 0.025) and baseline bone mineral density (BMD) measurements (OR = 0.52, 95% CI = 0.32-0.85; adjusted OR = 0.51; 95% CI = 0.28-0.93, p = 0.029) were less likely to have poor compliance.

CONCLUSIONS

Adherence to osteoporosis regimens in males was suboptimal in our study. Poor compliance was more likely in prescription of the first anti-osteoporotic regimen by an orthopedist. Men with RA and BMD measurements before therapy had a lower risk of non-adherence. Healthcare professionals need to target patients with specific factors to improve adherence to osteoporotic regimens.

Short- and long-term mortality in males and females with fragility hip fracture in Norway. A population-based study

Background

Hip fracture patients have, in several studies, been shown to have excessive mortality. There is, however, a lack of mortality data, in comparison to incidence data, from the last decade in particular.

Objective

To study short- and long-term mortality in a population-based cohort of hip fracture patients over the last decade and compare it to the background population.

Patients and methods

Fragility hip fracture patients in the two most southern counties in Norway who experienced fractures in 2004 and 2005 were studied. For each patient, three controls were randomly recruited from the background population matched for age, sex, and residency. Overall, age-, gender-, and group-specific mortality rates were calculated.

Results

A total of 942 (267 male and 675 female) patients with a fragility hip fracture were identified. In the hip fracture patients, overall mortality rate after 1 year was 21.3% (males 30.7% and females 19.1%, P < 0.005) and, after 5 years, 59.0% (males 70.0% and females 54.6%, P < 0.005). The corresponding figures for matched controls were 5.6% (males 5.9%, females 5.4%, P = 0.6) and 24.9% (males 25.9%, females 24.5%, P = 0.4), respectively. A statistically significant difference was seen in the log-rank statistical analysis between hip fracture patients and controls, both in males (P < 0.0005) and females (P < 0.0005), and for age groups 50–80 years (P < 0.0005) and 80 years and older (P < 0.0005).

Conclusion

Mortality in males and females with hip fractures is high not only in the first year after fracture, but remains higher than in the background population during 5 years of follow-up. The high mortality in hip fracture patients remains a challenge both in middle-aged and elderly individuals. Optimization of post-fracture treatment and care could reduce mortality of hip fracture in middle-aged and elderly individuals.

Surgical treatment of hip fractures: factors influencing mortality

BACKGROUND

Data for osteoporotic hip fractures in Greece is limited and little is known upon the meaning of family support during the postoperative/rehabilitation period.

OBJECTIVE

To identify the factors influencing the mortality after hip fractures in the elderly, the effect of rehabilitation and family support in the post-fracture course, and the impact of these fractures on the family of the injured elderly.

METHODS

We conducted an observational study of 218 consecutive patients older than 60 years of age, who underwent surgical management of a unilateral hip fracture at a tertiary hospital of Central Greece, with follow-up contacts at 30 days, 3 months and one year. Demographic characteristics, pre- and post-fracture residential and functional status, assessment of basic activities of daily living (ADL), co-morbidities, type and mechanism of fracture and hospitalization data as well as the modification of activities of the patients' relatives were recorded.

RESULTS

Fifteen patients (6.9%) died during hospitalization; thirty-nine (17.9%) died within one year of fracture. The factors that were predictive of in-hospital, 30-days and one-year mortality, based on multivariate analysis, were male sex, advanced age >85 and Charson index >3. There was a significant association between delayed surgery (>48 hours) and increased in-hospital mortality. The percentage of patients assessed as ADL A or B at baseline, decreased form 84% preoperatively to 50.4% one year postoperatively. Only one-third of patients walking without aid before the fracture returned to the previous state. Family members modified their activities in 48% of cases to assist their relatives with a hip fracture.

CONCLUSIONS

One-year mortality in patients with hip fractures was 17.9%. Surgical delay (>48 hours) increased in-hospital mortality. Comorbidities >3, male sex, and advanced age increased the risk of in-hospital and post-discharge mortality during the 1st year. Twelve months postoperatively, half of patients walking without aid before the fracture returned to the previous state. Despite the beneficial effect of family support, the lack of organized rehabilitation programs and geriatric units are potential negative factors for patients' functional outcome. In addition, 48% of patients' relatives changed their daily activities to assist their relatives.

Comprehensive and subacute care interventions improve health-related quality of life for older patients after surgery for hip fracture: a randomised controlled trial

BACKGROUND

Elderly patients with hip fracture have been found to benefit from subacute care interventions that usually comprise usual care with added geriatric intervention, early rehabilitation, and supported discharge. However, no studies were found on the effects of combining subacute care and health-maintenance interventions on health outcomes for elders with hip fracture.

OBJECTIVES

To compare the effects of an interdisciplinary comprehensive care programme with those of subacute care and usual care programmes on health-related quality of life (HRQoL) for elderly patients with hip fracture.

DESIGN

Randomised controlled trial.

SETTINGS

A 3000-bed medical centre in northern Taiwan.

PARTICIPANTS

Patients with hip fracture (N=299) were randomised into three groups: subacute care (n=101), comprehensive care (n=99), and usual care (n=99).

METHODS

Subacute care included geriatric consultation, continuous rehabilitation, and discharge planning. Comprehensive care consisted of subacute care plus health-maintenance interventions to manage depressive symptoms, manage malnutrition, and prevent falls. Usual care included only 1-2 in-hospital rehabilitation sessions, discharge planning without environmental assessment, no geriatric consultation, and no in-home rehabilitation. HRQoL was measured using the Medical Outcomes Study Short-Form 36 Taiwan version at 1, 3, 6, and 12 months after discharge.

RESULTS

Participants in the comprehensive care group improved more in physical function, role physical, general health and mental health than those in the usual care group. The subacute care group had greater improvement in physical function, role physical, vitality, and social function than the usual care group. The intervention effects for both comprehensive and subacute care increased over time, specifically from 6 months after hip fracture onward, and reached a maximum at 12 months following discharge.

CONCLUSIONS

Both comprehensive care and subacute care programmes may improve health outcomes of elders with hip fracture. Our results may provide a reference for health care providers in countries using similar programmes with Chinese/Taiwanese immigrant populations.

Comparing 15D and SF-6D performance in fragility wrist and hip fracture patients in a two-year follow-up case-control study

OBJECTIVES

To examine and compare the two utility and health-related quality-of-life (HRQOL) measures 15D and (SF-6D) in fragility wrist and hip fracture patients and controls, study the responsiveness of 15D and SF-6D, and examine the impact of these fractures on changes in 15D and SF-6D scores over 2 years.

METHODS

A total of 152 wrist fracture patients and 164 controls and 61 hip fracture patients and 61 controls with 15D and SF-6D scores were studied.

RESULTS

The mean 15D score decreased significantly in wrist fracture patients between baseline and 2-year follow-up (P=0.003). A wrist fracture was a significant predictor of a decrease in 15D scores 2 years after fracture (B=-0.016; P=0.049), along with low body mass index (B=-0.002; P=0.009). In hip fracture patients, both 15D and SF-6D scores decreased significantly (P<0.001). A hip fracture was a significant predictor of a decrease in 15D (B=-0.060; P=0.001) and SF-6D (B=-0.096; P=0.001) scores.

CONCLUSIONS

Our data suggest that a fragility wrist fracture has a long-term negative effect on HRQOL, but not as strong as for fragility hip fractures. 15D seems to be more responsive than SF-6D when assessing HRQOL in patients with fragility fractures.

Mortality after low trauma hip fracture: a prospective cohort study

BACKGROUND

Various risk of mortality due to hip fracture has been reported by different studies. There is scarce controlled study on hip fracture mortality from developing countries and no data from Middle East region. The objective of this study is to determine mortality and its risk factors one year after low trauma hip fracture.

METHODS

One hundred and two patients after hip fracture not caused by high impact injuries or local bone diseases followed up prospectively for one year. Control group consisted of sex and age matched patients admitted to ophthalmology ward for eye surgery. Data about comorbidity obtained from both groups at baseline. Functional state and health-related quality of life for the participants were measured using RDRS-2 and SF-36 questionnaires, respectively.

RESULTS

The overall survival was 83% in cases and 92% in controls (log rank test 3.62, df = 1, P = 0.057). Early mortality within the first 6 months of observation was significantly higher in patients than controls (13 in patients vs. 2 in controls) (log rank test 8.84, df = 1, P = 0.003). The risk of mortality in the first year after fracture was significantly and independently associated with age and baseline RDRS score. By the end of follow-up, in the patient group, 55.4% of survivors were able to walk without any assistance and 10.8% were not able to walk.

CONCLUSIONS

The risk of mortality within the first 6 months of observation was significantly and independently associated with low trauma hip fracture. However, age and baseline RDRS score were independent predictors of mortality in the first year following hip fracture.

Preoperative predictors for mortality following hip fracture surgery: a systematic review and meta-analysis

BACKGROUND

Hip fractures are always associated with a high postoperative mortality, the preoperative predictors for mortality have neither been well identified or summarised. This systematic review and meta-analysis was performed to identify the preoperative non-interventional predictors for mortality in hip fracture patients, especially focused on 1 year mortality.

METHODS

Non-interventional studies were searched in Pubmed, Embase, Cochrane central database (all to February 26th, 2011). Only prospective studies and retrospective studies with prospective collected data were included. Qualities of included studies were assessed by a standardised scale previous reported for observational studies. The effects of individual studies were combined with the study quality score using a previous reported model of best-evidence synthesis. The hazard ratios of strong evidence predictors were combined only by high quality studies.

RESULTS

75 included studies with 94 publications involving 64,316 patients were included and the available observations was a heterogeneous group. The overall inpatient or 1 month mortality was 13.3%, 3-6 months was 15.8%, 1 year 24.5% and 2 years 34.5%. There were strong evidence for 12 predictors, including advanced age, male gender, nursing home or facility residence, poor preoperative walking capacity, poor activities of daily living, higher ASA grading, poor mental state, multiple comorbidities, dementia or cognitive impairment, diabetes, cancer and cardiac disease. We also identified 7 moderate evidence and 12 limited evidence mortality predictors, and only the race was identified as the conflicting evidence predictor.

CONCLUSION

Whilst there is no conclusive evidence of the preoperative predictors for mortality following hip fractures, special attention should be paid to the above 12 strong evidence predictors. Future researches were still needed to evaluate the effects of these predictors.

Osteoporotic profiles in elderly patients with symptomatic lumbar spinal canal stenosis

BACKGROUND

The osteoporosis and lumbar canal stenosis, in elderly patients are under diagnosed and under reported. We report a cross sectional study to demonstrate the osteoporotic profile in patients with lumbar spinal stenosis (LSS) and to determine the proportion of patients with LSS who need to be treated for osteoporosis.

MATERIALS AND METHODS

One hundred and six postmenopausal patients with symptomatic LSS were evaluated for osteoporotic profile, which included lumbar and hip bone mineral density (BMD), serum vitamin D concentration, bone resorption and formation markers. Demographic and disease related variables were analyzed to identify the association with the risk of osteoporosis or osteopenia. Statistical analysis used were multivariate logistic regression with a forward stepwise procedure.

RESULTS

Twenty-four patients (22.6%) had osteoporosis and 60 (56.6%) had osteopenia. Overall, 84 patients (79.2%) with symptomatic LSS had osteoporosis or osteopenia. Fifty-nine patients (55.6%) had hypovitaminosis D. All bone turnover makers [alkaline phosphatase, osteocalcin, urinary-N-terminal telopeptide (u-NTx)] were demonstrated to be within normal range. Only age was associated with the risk of osteoporosis or osteopenia in the hip region. In the lumbar spine, all variables were not associated with osteoporosis or osteopenia. 44 patients (41.5%) required treatment for osteoporosis as per risk factors for osteoporosis. According to the guidelines from the Health Insurance Review Agency, however, only 20 patients (18.8% required) qualified for reimbursement for osteoporosis medications.

CONCLUSIONS

LSS is associated with osteopenia, osteoporosis, and hypovitaminosis D, which should prompt careful screening and treatment in cases of osteoporosis and osteoarthritis.
