Incidence and costs of hip fractures vs strokes and acute myocardial infarction in Italy: comparative analysis based on national hospitalization records

Osteoporotic Fractures: Diagnosis, Evaluation, and Significance From the International Working Group on DXA Best Practices

Osteoporotic fractures, also known as fragility fractures, are reflective of compromised bone strength and are associated with significant morbidity and mortality. Such fractures may be clinically silent, and others may present clinically with pain and deformity at the time of the injury. Unfortunately, and even at the time of detection, most individuals sustaining fragility fractures are not identified as having underlying metabolic bone disease and are not evaluated or treated to reduce the incidence of future fractures. A multidisciplinary international working group with representation from international societies dedicated to advancing the care of patients with metabolic bone disease has developed best practice recommendations for the diagnosis and evaluation of individuals with fragility fractures. A comprehensive narrative review was conducted to identify key articles on fragility fractures and their impact on the incidence of further fractures, morbidity, and mortality. This document represents consensus among the supporting societies and harmonizes best practice recommendations consistent with advances in research. A fragility fracture in an adult is an important predictor of future fractures and requires further evaluation and treatment of the underlying osteoporosis. It is important to recognize that most fragility fractures occur in patients with bone mineral density T scores higher than -2.5, and these fractures confirm the presence of skeletal fragility even in the presence of a well-maintained bone mineral density. Fragility fractures require further evaluation with exclusion of contributing factors for osteoporosis and assessment of clinical risk factors for fracture followed by appropriate pharmacological intervention designed to reduce the risk of future fracture. Because most low-trauma vertebral fractures do not present with pain, dedicated vertebral imaging and review of past imaging is useful in identifying fractures in patients at high risk for vertebral fractures. Given the importance of fractures in confirming skeletal fragility and predicting future events, it is recommended that an established classification system be used for fracture identification and reporting.

The role of the fracture liaison service in the prevention of atypical femoral fractures

Osteoporosis and fragility fractures (FFs) are considered critical health problems by the World Health Organization (WHO) because of high morbidity, mortality, and healthcare costs. The occurrence of a FF raises the risk of a subsequent fracture (refracture). The hip is the most common site of fragility refracture, and its onset is associated with a further increase in patient's morbidity, mortality, and socioeconomic burden. Therefore, the prevention of refracture is essential. In this context, fracture liaison service (FLS) demonstrated to be able to reduce FF risk and also improve patients' adherence to anti-osteoporotic treatments, particularly for bisphosphonates (BPs). However, long-term and high adherence to BPs may lead to atypical femoral fractures (AFFs). These latter are tensile side stress fractures of the femur, with high rates of complications, including delayed and non-healing. An effective FLS should be able to prevent both FF and AFF. A comprehensive and interdisciplinary approach, through the involvement and education of a dedicated team of healthcare professionals (i.e. orthopedic, geriatrician, primary care physician, rehabilitation team, and bone nurse) for evaluating both FF and AFF risks might be useful to improve the standard of care.

Cost-effectiveness analysis of pressure-controlled intermittent coronary sinus occlusion in elective percutaneous coronary intervention

OBJECTIVES

Percutaneous coronary intervention (PCI) represents the standard treatment for ST-elevated myocardial infarction, nevertheless, mortality and heart failures are frequent. Pressure-controlled intermittent coronary sinus occlusion (PiCSO) might reduce infarct size showing better patients' outcomes. We evaluated the cost-effectiveness of PCI+PiCSO compared to PCI from the National Healthcare Service (NHS) perspective in Italy.

METHODS

A Markov model was developed to estimate life years (LYs), quality-adjusted life years (QALYs) and costs. A micro-costing analysis has been performed to inform the cost of PCI+PiCSO procedure. Sensitivity analyses were performed to test the robustness of the model results.

RESULTS

Considering a willingness-to-pay threshold of 50,000€/QALY for the ICUR and a cost for PCI+PiCSO procedure of 14,654€, the innovative strategy may be cost-effective compared to PCI alone from the Italian NHS perspective, showing an ICUR of 17,530€/QALY (ICER 14,631€/LY) over a lifetime horizon; the probabilistic sensitivity analysis showed that PCI+PiCSO is cost-effective in 78.8% of simulations.Considering the above mentioned willingness-to-pay threshold, PCI+PiCSO strategy would be cost-effective over a lifetime horizon considering a cost for PCI+PiCSO procedure lower than 28,160€.

CONCLUSION

PCI+PiCSO procedure may be considered a cost-effective technology that allows reducing cardiac events, while improving patients' life expectancy and quality of life.

Osteoporotic fracture admissions compared to other major medical admissions in Irish public hospitals

Multinational reports suggest Ireland has one of the greatest illness burdens related to osteoporosis. Hospital care represents the costliest portion of health services. We found public hospital bed days for fragility fractures in Ireland increased by 43% between 2008 and 2017 which exceeded those for other common diseases.

INTRODUCTION

Recent multinational reports suggest Ireland has one of the greatest illness burdens related to osteoporosis, manifesting clinically as fragility fractures (FF). International reports show that FF incidence, rate of hospital admission and cost are similar or greater than those for breast cancer, myocardial infarction and stroke. Studies addressing the illness burden of osteoporosis in Ireland are few, and none compares fragility fractures to other common chronic diseases.

METHODS

A retrospective analysis of national administrative data for all public hospital admissions was performed on adults aged 50 years and older from January 2008 to December 2017.

RESULTS

In 2017, public hospital bed days for FF totalled 249,887 outnumbering Chronic Obstructive Pulmonary Disease (COPD): 131,897; 6 solid cancers (CA): 118,098; myocardial infarction (MI): 83,477; and diabetes mellitus (DM): 31,044. Bed days for FF increased by 43% between 2008 and 2017, in contrast to a 32%, 28% and 31% reduction for CA, MI and DM, respectively, and a 12% increase for COPD. Public hospital bed days for FF in 2016 were greater than MI, stroke, atrial fibrillation and chest pain combined but less than a combination of COPD, pneumonia and lower respiratory tract infection.

CONCLUSION

Osteoporotic fractures represent a large and rapidly increasing illness burden amongst older Irish adults, with substantial care requirements and the resulting onus on our healthcare system. Urgent action is needed to address this public health issue and the services for those at risk of fracture.

Risk assessment tools for osteoporosis and fractures in 2022

Osteoporosis is one of the frequently encountered non-communicable diseases in the world today. Several hundred million people have osteoporosis, with many more at risk. The clinical feature is a fragility fracture (FF), which results in major reductions in the quality and quantity of life, coupled with a huge financial burden. In recognition of the growing importance, the World Health Organisation established a working group 30 years ago tasked with providing a comprehensive report to understand and assess the risk of osteoporosis in postmenopausal women. Dual-energy X-ray absorptiometry (DXA) is the most widely endorsed technology for assessing the risk of fracture or diagnosing osteoporosis before a fracture occurs, but others are available. In clinical practice, important distinctions are essential to optimise the use of risk assessments. Traditional tools lack specificity and were designed for populations to identify groups at higher risk using a 'one-size-fits-all' approach. Much has changed, though the purpose of risk assessment tools remains the same. In 2022, many tools are available to aid the identification of those most at risk, either likely to have osteoporosis or suffer the clinical consequence. Modern technology, enhanced imaging, proteomics, machine learning, artificial intelligence, and big data science will greatly advance a more personalised risk assessment into the future. Clinicians today need to understand not only which tool is most effective and efficient for use in their practice, but also which tool to use for which patient and for what purpose. A greater understanding of the process of risk assessment, deciding who should be screened, and how to assess fracture risk and prognosis in older men and women more comprehensively will greatly reduce the burden of osteoporosis for patients, society, and healthcare systems worldwide. In this paper, we review the current status of risk assessment, screening and best practice for osteoporosis, summarise areas of uncertainty, and make some suggestions for future developments, including a more personalised approach for individuals.

Efficacy of a multiple-component and multifactorial personalized fall prevention program in a mixed population of community-dwelling older adults with stroke, Parkinson's Disease, or frailty compared to usual care: The PRE.C.I.S.A. randomized controlled trial

Background

Fall risk in the elderly is a major public health issue due to the injury-related consequences and the risk of associated long-term disability. However, delivering preventive interventions in usual clinical practice still represents a challenge.

Aim

To evaluate the efficacy of a multiple-component combined with a multifactorial personalized intervention in reducing fall rates in a mixed population of community-dwelling elderly compared to usual care.

Design

Randomized Controlled Trial (NCT03592420, clinicalTrials.gov).

Setting

Outpatients in two Italian centers.

Population

403 community-dwelling elderly at moderate-to-high fall risk, including subjects with Parkinson's Disease and stroke.

Methods

After the randomization, the described interventions were administered to the intervention group (n = 203). The control group (n = 200) received usual care and recommendations to minimize fall risk factors. In addition, each participant received a fall diary, followed by 12 monthly phone calls. The primary endpoint was the total number of falls in each group over 12 months, while the secondary endpoints were other fall-related indicators recorded at one year. In addition, participants' functioning was assessed at baseline (T1) and 3-month (T3).

Results

690 falls were reported at 12 months, 48.8% in the intervention and 51.2% in the control group, with 1.66 (± 3.5) and 1.77 (± 3.2) mean falls per subject, respectively. Subjects with ≥ 1 fall and ≥2 falls were, respectively, 236 (58.6%) and 148 (36.7%). No statistically significant differences were observed between groups regarding the number of falls, the falling probability, and the time to the first fall. According to the subgroup analysis, no significant differences were reported. However, a statistically significant difference was found for the Mini-BESTest (p = 0.004) and the Fullerton Advanced Balance Scale (p = 0.006) for the intervention group, with a small effect size (Cohen's d 0.26 and 0.32, respectively), at T1 and T3 evaluations.

Conclusions

The intervention was ineffective in reducing the number of falls, the falling probability, and the time to the first fall at 12 months in a mixed population of community-dwelling elderly. A significant improvement for two balance indicators was recorded in the intervention group. Future studies are needed to explore different effects of the proposed interventions to reduce falls and consequences.

Costs of patient management over 18 months following a hip, clinical vertebral, distal forearm, or proximal humerus fragility fracture in France-results from the ICUROS study

This observational study prospectively assessed direct and indirect costs related to patient management over 18 months following hip, clinical vertebral, humeral, or distal forearm fracture events in France. It appears that their levels were much higher than the previous estimates, raising the burden of osteoporosis-related fractures on public health expenditures.

INTRODUCTION

This prospective observational study assessed the costs related to patient management over the 18-month period following the event of a hip, clinical vertebral, humeral, or distal forearm fracture in France.

METHODS

Individuals aged ≥ 50 years old with the diagnosis of a fragility fracture in six French University Hospitals were enrolled in the International Costs and Utilities Related to Osteoporotic Fractures Study (ICUROS). All resources used over the defined period and related to fracture and the underlying osteoporosis management were collected by questionnaires at baseline, 4 months, 12 months, and 18 months. Information was collected by direct or phone contact completed by patients' records and interviews of partner, family, and general practitioners. Costs were estimated from a societal perspective, including direct and indirect costs. We implemented recursive partitioning analysis (RPA), a statistical learning algorithm to identify predictors of costs.

RESULTS

Four hundred thirty-one patients (mean age 72.5 years; 84.6% women) were evaluated. Among them, 17.6% had a prior fracture in the last 5 years. Approximately half of the whole group lived alone in the community, and 56.8% were from a low- or middle-income category. Over the 18-month period of evaluation, total costs (including initial fracture-related and follow-up ones) were 23 926 €, 14 561 €, and 6 905 € for the hip, clinical vertebral, and distal forearm fracture, respectively. Over a year, costs related to a humeral fracture were 10 319 €. The RPA identified mobility impairment prior to fracture as a predictor of increase in costs related to fracture.

CONCLUSIONS

Our study for the first time prospectively assessed total costs related to the four main osteoporotic fractures in France. It appears that their levels were much higher than previous estimates, raising the burden of osteoporosis-related fractures on public health expenditures.

The cost-effectiveness of transcatheter aortic valve implantation: exploring the Italian National Health System perspective and different patient risk groups

OBJECTIVES

To assess the cost-effectiveness (CE) of transcatheter aortic valve implantation (TAVI) in Italy, considering patient groups with different surgical risk.

METHODS

A Markov model with a 1-month cycle length, comprising eight different health states, defined by the New York Heart Association functional classes (NYHA I-IV), with and without stroke plus death, was used to estimate the CE of TAVI for intermediate-, high-risk and inoperable patients considering surgical aortic valve replacement or medical treatment as comparators according to the patient group. The Italian National Health System perspective and 15-year time horizon were considered. In the base-case analysis, effectiveness data were retrieved from published efficacy data and total direct costs (euros) were estimated from national tariffs. A scenario analysis considering a micro-costing approach to estimate procedural costs was also considered. The incremental cost-effectiveness ratio (ICER) was expressed both in terms of costs per life years gained (LYG) and costs per quality adjusted life years (QALY). All outcomes and costs were discounted at 3% per annum. Univariate and probabilistic sensitivity analyses (PSA) were performed to assess robustness of results.

RESULTS

Over a 15-year time horizon, the higher acquisition costs for TAVI were partially offset in all risk groups because of its effectiveness and safety profile. ICERs were €8338/QALY, €11,209/QALY and €10,133/QALY, respectively, for intermediate-, high-risk and inoperable patients. ICER values were slightly higher in the scenario analysis. PSA suggested consistency of results.

CONCLUSIONS

TAVI would be considered cost-effective at frequently cited willingness-to-pay thresholds; further studies could clarify the CE of TAVI in real-life scenarios.

Frailty, post-operative delirium and functional status at discharge in patients with hip fracture

OBJECTIVE

To explore the effect of frailty, alone and in combination with post-operative delirium (POD), on the risk of poor function at discharge in patients with hip fracture (HF).

METHODS

This is a prospective cohort study of patients with HF admitted to an Orthogeriatric Unit (OGU) between October 1, 2011 and March 15, 2019. POD was assessed using the 4AT and the Diagnostic and Statistical Manual of Mental Disorders (DSM) 5-edition criteria. A 22-items Frailty Index (FI) was created using the data collected on admission. The outcome measure was the Cumulated Ambulation Score (CAS) score at discharge. A log-binomial regression model was used to assess the effect of frailty and POD on CAS.

RESULTS

A total of 988 patients (median age = 84.9 years, Interquartile range = 80.6-89.2) were included: 360 patients (36.4%) were frail and 411 (42%) developed POD. Poor functional status at discharge (CAS score ≤2) was more common in frail than non-frail patients (68.3% vs. 53.8%, p < 0.001) In a regression adjusted for confounders, frailty alone (Relative Risk, RR = 1.33, 95% Confidence Intervals, CI = 1.14-1.55) and POD alone (RR 1.38, 95% CI = 1.2-1.59) were associated with poor functional status at discharge; when combined, frailty and POD had an interaction, yielding a mild increase in the risk of poor outcome (RR 1.47, 95% CI = 1.28-1.69).

CONCLUSIONS

In older patients undergoing HF surgery, frailty, POD and their combination, are associated with poor functional status at discharge.

Atypical periprosthetic femoral fractures of the hip: A PRISMA compliant systematic review

INTRODUCTION

Long-term use of bisphosphonates (BPs) is associated with Atypical Femoral Fracture (AFF). Theoretically, periprosthetic femoral fractures (PFF) should be excluded from the diagnosis of AFF. However, recently several studies reported the occurrence of PPFs around a hip arthroplasty presenting features of an AFF. The present study describes the characteristics of Atypical Periprosthetic Femoral Fracture (APFF) and evaluates the effectiveness of their management through a PRISMA compliant systematic review of the published case reports and series.

MATERIALS AND METHODS

A literature search was performed using "periprosthetic fracture" and "atypical femoral fracture" as keywords. Patients demographics, drug use, clinical and imaging characteristics, stem fixation and classification, management strategies for APFF and patients' outcomes, were also collected.

RESULTS

The present review included and analysed 17 patients from 12 studies. All APFFs occurred in females with a mean age of 75.9 years of age (range 43-87). In 11 patients, APFFs occurred around an uncemented stem, and in 6 around a cemented stem. Ten fractures were incomplete, and 7 complete. Conservative management was effective in 4 of 10 patients with incomplete fracture, while all patients with complete fractures underwent open reduction and internal fixation. A fracture non-union was observed in 5 patients and further surgery was required.

DISCUSSIONS

APFFs share several clinical and imaging characteristics with AFF. An appropriate and early diagnosis may allow to improve the outcome of these fractures, the management of which should be based on the same principles of that of AFFs.

CONCLUSIONS

Considering the low quality of published articles and the heterogeneity of the treatment used, a clear recommendation of the most appropriate treatment cannot be formulated.

Association between preoperative evaluation with lung ultrasound and outcome in frail elderly patients undergoing orthopedic surgery for hip fractures: study protocol for an Italian multicenter observational prospective study (LUSHIP)

BACKGROUND

Hip fracture is one of the most common orthopedic causes of hospital admission in frail elderly patients. Hip fracture fixation in this class of patients is considered a high-risk procedure. Preoperative physical examination, plasma natriuretic peptide levels (BNP, Pro-BNP), and cardiovascular scoring systems (ASA-PS, RCRI, NSQIP-MICA) have all been demonstrated to underestimate the risk of postoperative complications. We designed a prospective multicenter observational study to assess whether preoperative lung ultrasound examination can predict better postoperative events thanks to the additional information they provide in the form of "indirect" and "direct" cardiac and pulmonary lung ultrasound signs.

METHODS

LUSHIP is an Italian multicenter prospective observational study. Patients will be recruited on a nation-wide scale in the 12 participating centers. Patients aged  >  65 years undergoing spinal anesthesia for hip fracture fixation will be enrolled. A lung ultrasound score (LUS) will be generated based on the examination of six areas of each lung and ascribing to each area one of the four recognized aeration patterns-each of which is assigned a subscore of 0, 1, 2, or 3. Thus, the total score will have the potential to range from a minimum of 0 to a maximum of 36. The association between 30-day postoperative complications of cardiac and/or pulmonary origin and the overall mortality will be studied. Considering the fact that cardiac complications in patients undergoing hip surgery occur in approx. 30% of cases, to achieve 80% statistical power, we will need a sample size of 877 patients considering a relative risk of 1.5.

CONCLUSIONS

Lung ultrasound (LU), as a tool within the anesthesiologist's armamentarium, is becoming increasingly widespread, and its use in the preoperative setting is also starting to become more common. Should the study demonstrate the ability of LU to predict postoperative cardiac and pulmonary complications in hip fracture patients, a randomized clinical trial will be designed with the scope of improving patient outcome.

Cost-Effectiveness of Direct Non-Vitamin K Oral Anticoagulants Versus Vitamin K Antagonists for the Management of Patients with Non-Valvular Atrial Fibrillation Based on Available "Real-World" Evidence: The Italian National Health System Perspective

BACKGROUND AND OBJECTIVE

The increasing availability of real-world evidence (RWE) about safety and effectiveness of direct non-vitamin K oral anticoagulants (DOACs) for the management of atrial fibrillation (AF) offers the opportunity to better understand the clinical and economic implications of DOACs versus vitamin K antagonists (VKAs). The objective of this study was to compare the economic implications of DOACs and VKAs using data from real-world evidence in patients with AF.

METHODS

A Markov model simulating the lifetime course of patients diagnosed with non-valvular AF was used to evaluate the cost-effectiveness of DOACs (i.e., rivaroxaban, dabigatran and apixaban) versus VKAs from the Italian National Health System (INHS) perspective. The model was made up of data from the literature and a meta-analysis of RWE on the incidence of stroke/systemic embolism (SE), major bleeding (MB), intracranial haemorrhage (ICH) and all-cause mortality (ACM); direct costs included drug costs, costs for drug monitoring, and management of events from official national lists. One-way and probabilistic sensitivity analyses (PSA) were used to assess the robustness of the results.

RESULTS

Results from the meta-analysis showed that apixaban had a high probability of being the most effective for stroke/SE, MB and ACM. Despite their higher acquisition costs, the cost-effectiveness analysis showed all DOACs involved a saving when compared with VKAs, with per-patient savings ranging between €4647 (rivaroxaban) to €6086 (apixaban). Moreover, all DOACs indicated a gain both in quality-adjusted life-years and life-years. According to PSA, findings related to apixaban were consistent, while for dabigatran and rivaroxaban PSA revealed a higher degree of uncertainty.

CONCLUSIONS

The beneficial effect of DOACs on containing events showed in RWE had the potential to offset drug-related costs, thus improving the sustainability of treatment for non-valvular AF in daily clinical practice.

The clinical and economic burden of proximal femur periprosthetic fractures

BACKGROUND

The number of hip replacements is constantly and progressively increasing, resulting in an increase in periprosthetic fractures. The main aim of this study is to analyze costs and outcomes of surgical treatment for those fractures.

MATERIALS AND METHODS

A retrospective study was performed on periprosthetic proximal femur fracture presented a single-level I trauma center. Medical records were reviewed in terms of demographic data, diagnosis (according to Vancouver classification), type of surgical treatment, hospitalization length and follow-up. Patients were interviewed about number of consultations after discharge, medications and physiotherapy sessions. Clinical outcome was evaluated with WOMAC score at the last follow-up, and patient health status was evaluated with the EQ5D5L score pre-trauma and at the last follow-up. Patients were divided into two groups according to surgical treatment: reduction and internal fixation alone and revision plus fixation. A further group was also considered: patients underwent a Girdlestone procedure. Global costs for each group were calculated.

RESULTS

We initially recruited 117 patients, 17 of them were lost at follow-up. Furthermore, 19 patients (19%) died during the follow-up, and 81 of them were therefore included in the study. Mean follow-up was 26.5 months. Mean postoperative WOMAC score was 39.44, and EQ5D5L score was 9.12 for the preoperative period and 12.35 at the last follow-up. A significant worsening of clinical conditions was found comparing the period before fracture to the last follow-up (p < 0.01). Quality of life after surgery resulted to be poor or fair in 40% of the patients at a mean follow-up of 26.5 months. No significant differences between groups were found according to patients' health status. Mean global costs for mayor surgeries were 18,822 Euros; mean costs for fixation alone were 17,298 Euros while for fixation and revision were 20,966 Euros, but no statistically difference was found between these two groups. Mean cost for Girdlestone group was 12,664 Euros.

CONCLUSIONS

In proximal femur periprosthetic fractures, either fixation or revision plus fixation presents high costs but patients' postoperative quality of life is poor.

Trends in hip and distal femoral fracture rates in Italy from 2007 to 2017

Osteoporosis-related fractures are a growing public health concern worldwide due to high societal and economic burden. The study aims to assess trends in incidence rates of hip and distal femoral fractures and in the use of anti-osteoporosis drugs in Italy between 2007 and 2017. Patients with hip and distal femoral fractures (ICD-9-CM codes 820.x and 821.x) were identified in the Italian National Hospital Discharge Database while anti-osteoporosis medication data were retrieved from the National Observatory on the Use of Medicines Database. A joinpoint regression analysis was performed to identify the years where the trends in incidence rates of hip and distal femoral fractures changed significantly; the average annual percentage change for the period of observation was estimated. Hospitalizations for femoral fractures were 991,059, of which 91.4% were hip fractures and 76.5% occurred in women. Age-standardized hip fractures rate per 100,000 person-years decreased both in women (-8.7%; from 789.9 in 2007 to 721.5 in 2017) and in men (-4.3%; from 423.9 to 405.6), while the rate of distal femoral fractures increased by 23.9% in women (from 67.78 to 83.95) and 22.7% in men (from 27.76 to 34.06). These changes were associated with an increment in the use of anti-osteoporosis drugs from 2007 to 2011 (from 9.1 to 12.4 DDD/1000 inhabitants/day), followed by a plateau in the period 2012-2017. The use of bisphosphonates increased progressively from 2007 to 2010 (from 8.2 to 10.5 DDD/1000 inhabitants/day), followed by a plateau and then decreased from 2015 onwards. The decreasing trend of hip fractures could be related to a major intake of anti-osteoporosis medications while the increment of distal femoral fractures might be due to population aging and to the use of bisphosphonates and denosumab. Further research is needed to identify and implement interventions to prevent hip and distal femoral fractures.

The Irish dual-energy X-ray absorptiometry (DXA) Health Informatics Prediction (HIP) for Osteoporosis Project

PURPOSE

The purpose of the Irish dual-energy X-ray absorptiometry (DXA) Health Informatics Prediction (HIP) for Osteoporosis Project is to create a large retrospective cohort of adults in Ireland to examine the validity of DXA diagnostic classification, risk assessment tools and management strategies for osteoporosis and osteoporotic fractures for our population.

PARTICIPANTS

The cohort includes 36 590 men and women aged 4-104 years who had a DXA scan between January 2000 and November 2018 at one of 3 centres in the West of Ireland.

FINDINGS TO DATE

36 590 patients had at least 1 DXA scan, 6868 (18.77%) had 2 scans and 3823 (10.45%) had 3 or more scans. There are 364 unique medical disorders, 186 unique medications and 46 DXA variables identified and available for analysis. The cohort includes 10 349 (28.3%) individuals who underwent a screening DXA scan without a clear fracture risk factor (other than age), and 9947 (27.2%) with prevalent fractures at 1 of 44 skeletal sites.

FUTURE PLANS

The Irish DXA HIP Project plans to assess current diagnostic classification and risk prediction algorithms for osteoporosis and fractures, identify the risk predictors for osteoporosis and develop novel, accurate and personalised risk prediction tools, by using the large multicentre longitudinal follow-up cohort. Furthermore, the dataset may be used to assess, and possibly support, multimorbidity management due to the large number of variables collected in this project.

The impact of second hip fracture on rehospitalization and mortality in older adults

PURPOSE

Although a second hip fracture is not uncommon in the older population, the extent to which such an event may affect health-related outcomes has not been fully clarified. We aimed to evaluate the risk of new falls, functional decline, rehospitalization, institutionalization and mortality in older patients admitted for a second vs. a first hip fracture.

METHODS

The sample consisted of 288 older patients admitted to the Orthogeriatric Unit of Bolzano Hospital (northern Italy) and surgically treated for a hip fracture from June 2016 to June 2017. Socio-demographic data and hospitalization-related information were collected and a multidimensional assessment was made upon admission and during the hospital stay. Fifteen months after discharge, data on mobility level, functional status, institutionalization, and new falls were obtained from personal or structured phone interviews. Information on rehospitalization and mortality was obtained from local hospital registers.

RESULTS

One out of six patients (14.6 %) admitted was suffering a second hip fracture, of which only 16.7 % were on antiresorptive therapies. At the 15-month follow-up, individuals who had been treated for a second hip fracture were more likely than those treated for their first to have low mobility levels (OR = 4.13, 95 %CI:1.23-13.84), to be rehospitalized (OR = 2.57, 95 %CI:1.12-5.90), and to have a higher mortality (HR = 1.81, 95 %CI:1.05-3.12).

CONCLUSIONS

The occurrence of a second hip fracture may further affect the clinical vulnerability and mortality of older adults. These results highlight the need to implement preventive action to minimize the risk of re-fracture after the first event.

Three-year National report from the Gruppo Italiano di Ortogeriatria (GIOG) in the management of hip-fractured patients

BACKGROUND

Hip fractures (HF) are a major issue worldwide. We aimed at evaluating the practices in delivering care to patients with HF among several Italian Orthogeriatric centers.

METHODS

The study took place from February 2016 to July 2018. Seven performance indicators (pre-surgical cognitive assessment, surgery performed ≤ 48 h from fracture, removal of urinary catheter/absence of delirium/start of physiotherapy on the first post-operative day, prescription of bone protection at discharge, and discharge toward rehabilitation) were collected.

RESULTS

The 14 participating hospitals totally recruited 3.017 patients. Patients were old (median age 86 years; Inter Quartile Range [IQR] 80-90), mostly females (77%). Nearly 55% of them were already impaired in mobility and about 10% were nursing home residents. Median time-to-surgery was 41 h (IQR 23-62). Models of care greatly varied among centers, only 49.3% of patients being co-managed by geriatricians and orthopedics. There was high variability across centers in four indicators ("pre-surgical cognitive assessment", "bone protection prescription", "use of urinary catheter" and "start of physiotherapy"), moderate in two indicators ("surgery performed ≤ 48 h from fracture" and "discharge toward rehabilitation" and low in one ("absence of delirium on day following surgery"). Comparison with international studies suggests very different ways of providing care to HF Italian patients.

CONCLUSIONS

The study results suggest high inter-center variability in the key-performance indicators, and different approaches in providing care to our HF patients in comparison to other countries. A National debate on the topic is required in Italy to harmonize practices of orthogeriatric care.

"Our Tradition Our Enemy": A Qualitative Study of Barriers to Women's HIV Care in Jimma, Southwest Ethiopia

Evidence exists that suggests that women are vulnerable to negative HIV treatment outcomes worldwide. This study explored barriers to treatment outcomes of women in Jimma, Southwest Ethiopia. We interviewed 11 HIV patients, 9 health workers, 10 community advocates and 5 HIV program managers from 10 institutions using an in-depth interview guide designed to probe barriers to HIV care at individual, community, healthcare provider, and government policy levels. To systematically analyze the data, we applied a thematic framework analysis using NVivo. In total, 35 participants were involved in the study and provided the following interrelated barriers: (i) Availability— most women living in rural areas who accessed HIV cared less often than men; (ii) free antiretroviral therapy (ART) is expensive—most women who have low income and who live in urban areas sold ART drugs illegally to cover ART associated costs; (iii) fear of being seen by others—negative consequences of HIV related stigma was higher in women than men; (iv) the role of tradition—the dominance of patriarchy was found to be the primary barrier to women’s HIV care and treatment outcomes. In conclusion, barriers related to culture or tradition constrain women’s access to HIV care. Therefore, policies and strategies should focus on these contextual constrains.

Pharmacological Therapy of Osteoporosis: What's New?

Osteoporosis and fragility fractures are relevant health issues because of their impact in terms of morbidity, mortality, and socioeconomic burden. Despite this alarming scenario, both underdiagnosis and undertreatment are common features of osteoporotic patients, particularly those who have already sustained a fragility fracture. Pharmacotherapy of osteoporosis is the main treatment option for these patients because of strong evidence about the efficacy of available drugs targeting bone metabolism. However, several issues can interfere with the effectiveness of anti-osteoporotic drugs in clinical practice, such as lack of awareness of both healthcare providers and patients, poor adherence to therapy, and safety in long-term treatment. Therefore, new therapeutic strategies have been proposed to overcome these problems, such as sequential therapy or emerging molecules mainly targeting the stimulation of bone formation. In particular, abaloparatide has been demonstrated to reduce major nonvertebral fracture risk compared with both placebo and teriparatide, although the European Medicines Agency (EMA) refused the marketing authorization because the benefits of this drug did not outweigh its risks. On the other side, EMA has recently approved romosozumab, a monoclonal antibody directed against sclerostin and the only available therapeutic option targeting Wnt signaling, as both bone-forming and antiresorptive intervention to treat osteoporosis and fragility fractures.

Fragility Fracture Prevention-Implementing a Fracture Liaison Service in a High Volume Orthopedic Hospital

Fragility fractures pose a serious threat to patient health, quality of life, and healthcare sustainability. In order to reduce their clinical, social, and economic burden, a Fracture Liaison Service (FLS) was introduced in a high volume orthopedic hospital in 2017. The purpose of this retrospective observational study is to describe the FLS protocol, introduce its preliminary outcomes, and provide an early evaluation in light of international guidelines and recommendations. All the performances suggested by the International Osteoporosis Foundation (IOF) are provided under the same institution by which a patient is admitted for surgery. Clinical indicators from patient history and administrative indicators from the hospital database have been used to estimate the spread of fragility fracture prevention and the degree of patient compliance to these programs. The research included 403 patients. Although, almost 1/3 were admitted for the second fragility fracture, only half received anti-osteoporotic treatment before it. The degree of prevention was even lower in the case of patients admitted for the first fragility fracture. The risk of being affected by a secondary fracture was seven times higher when patients did not attend any follow-up or diagnostic exam. In order to identify the main determinants of compliance with FLS and perform a cost-effectiveness analysis on a larger sample, it is fundamental to integrate data from different providers.

Bone alterations in inflammatory bowel diseases

Inflammatory bowel diseases (IBDs) are characterized by a multifactorial partially unknown etiology that involves genetic, immunological and environmental factors. Up to 50% of IBD patients experience at least one extraintestinal manifestation; among them is the involvement of bone density which is referred to as metabolic bone disease (MBD), including osteopenia and osteoporosis. Bone alterations in IBDs population appear to have a multifactorial etiology: Decreased physical activity, inflammation-related bone resorption, multiple intestinal resections, dietary malabsorption of minerals and vitamin D deficiency, genetic factors, gut-bone immune signaling interaction, steroid treatment, microbiota and pathogenic micro-organisms interaction, and dietary malabsorption of minerals, that, all together or individually, may contribute to the alteration of bone mineral density. This review aims to summarize the prevalence and pathophysiology of metabolic bone alterations in IBD subjects outlining the main risk factors of bone fragility. We also want to underline the role of the screening and prophylaxis of bone alterations in Crohn’s disease and ulcerative colitis patients and the importance of treating appropriately MBD.

The orthogeriatric comanagement improves clinical outcomes of hip fracture in older adults

Treatment of older adults with hip fracture is a healthcare challenge. Orthogeriatric comanagement that is an integrated model of care with shared responsibility improves time to surgery and reduces the length of hospital stay and mortality compared with orthopedic care with geriatric consultation service and usual orthopedic care, respectively.

INTRODUCTION

Treatment of fractures in older adults is a clinical challenge due partly to the presence of comorbidity and polypharmacy. The goal of orthogeriatric models of care is to improve clinical outcomes among older people with hip fractures. We compare clinical outcomes of persons with hip fracture cared according to orthogeriatric comanagement (OGC), orthopedic team with the support of a geriatric consultant service (GCS), and usual orthopedic care (UOC).

METHODS

This is a single-center, pre-post intervention observational study with two parallel arms, OGC and GCS, and a retrospective control arm. Hip fracture patients admitted to the trauma ward were assigned by the orthopedic surgeon to the OGC (n = 112) or GCS (n = 108) group. The intervention groups were compared each with others and both with the retrospective control group (n = 210) of older adults with hip fracture. Several clinical indicators are considered, including time to surgery, length of stay, in-hospital, and 1-year mortality.

RESULTS

Patients in the OGC (OR 2.62; CI 95% 1.40-4.91) but not those in the GCS (OR 0.74; CI 95% 0.38-1.47) showed a higher probability of undergoing surgery within 48 h compared with those in the UOC. Moreover, the OGC (β, - 1.08; SE, 0.54, p = 0.045) but not the GCS (β, - 0.79; SE, 0.53, p = 0.148) was inversely associated with LOS. Ultimately, patients in the OGC (OR 0.31; CI 95 % 0.10-0.96) but not those in the GCS (OR 0.37; CI 95% 0.10-1.38) experienced a significantly lower 1-year mortality rate compared with those in the UOC. All analyses were independent of several confounders.

CONCLUSIONS

Older adults with hip fracture taken in care by the OGC showed better clinical indicators, including time to surgery, length of stay and mortality, than those managed by geriatric consultant service or usual orthopedic care.

ABO system is not associated with proximal femoral fracture pattern in Southern Italy

INTRODUCTION:

The mechanism that leads to a given fracture pattern is not understood. Heredity could act in this field through the ABO system. We investigated the relationship between ABO blood system and hip fracture pattern in a population from Southern Italy.

METHODS:

Hip fractures were identified through a registry evaluation of the activity of a level I Hospital, and subsequently classified in 'intracapsular' or 'extracapsular' according to their anatomical location. Information on these patients' ABO blood type was collected and compared with general population data from the report on blood donors of the Salerno division of Italian Blood Volunteers Association (AVIS).

RESULTS:

590 hip fractures were included (414 extracapsular, 176 intracapsular) and compared with 709 blood donors. Fractured patients presented a blood group A more often and blood group O less often than the AVIS population ( p A vs. non-A = 0.0033; p O vs. non-O = 0.0024). None of the ABO blood groups were associated with fracture pattern ( p O vs. non-O = 0.5858, p A vs. non-A = 0.409; p B vs. non-B = 0.253; p AB vs. non-AB = 0.212). The rhesus factor was not associated the fracture pattern ( p = 0.34).

CONCLUSIONS:

The ABO blood type could play a role as a risk factor for proximal femoral fractures, but in our population its relevance in influencing the fracture pattern is unclear.

Impact of bundled payments on hip fracture outcomes: a nationwide population-based study

Objective

Establishing one price for all bundled services for a particular illness, which has become the key to healthcare reform efforts, is designed to encourage health professionals to coordinate their care for patients. Limited information is available, however, concerning whether bundled payments are associated with changes in patient outcomes. Nationwide longitudinal population-based data were used to examine the effect of bundled payments on hip fracture outcomes.

Design

An interrupted time series design with a comparison group.

Setting

General acute care hospitals throughout Taiwan.

Participants

A total of 178 586 hip fracture patients admitted over the period 2007-12 identified from the Taiwan's National Health Insurance Research Database.

Intervention

Bundled payments for hip fractures were implemented in Taiwan in January 2010.

Main Outcome Measures

The 30-day unplanned readmission and postdischarge mortality. Segmented generalized estimating equation regression models were used after adjustment for trends, patient, physician and hospital characteristics to assess the effect of bundled payments on 30-day outcomes for hip fracture compared with a reference condition.

Results

The 30-day unplanned readmission rate for hip fracture showed a relative decreasing trend after the implementation of bundled payments compared with the trend before the implementation relative to that of the reference condition.

Conclusions

This finding might imply that the implementation of bundled payments encourages health professionals to coordinate their care, leading to reduced readmission for hip fracture.

Caregivers' misperception of the severity of hip fractures

PURPOSE

The aim of our study was to evaluate how the caregiver of a hip fracture patient perceives the patient's health status and autonomy in the period immediately preceding the acute event and whether these judgments are actually in line with the prognosis predicted by the medical team caring for the patient in the rehabilitation structure.

PATIENTS AND METHODS

We enrolled 147 patients of both sexes, aged ≥65 years, who were referred to our center following surgical treatment of hip fractures of various nature. At the beginning of the rehabilitation program, each patient's caregiver was asked to complete the Blaylock Risk Assessment Screening Score (BRASS) questionnaire. The same questionnaire was compiled contemporaneously by the doctor taking care of the patient.

RESULTS

Analysis of the data shows that the caregivers tend to assign lower scores than the doctor, with a mean difference in agreement with the Bland-Altman plot of -2.43, 95% CI=-2.93 to -1.93, t-test P<0.001. Furthermore, differences in objectivity emerge in the evaluation of the clinical problems of the patient in a borderline clinical condition.

CONCLUSION

This study revealed that caregivers systematically misperceive the clinical situation of hip fracture patients prior to the acute event. Altered perception of such an important factor can lead to a general lack of satisfaction with the outcome achieved by the patient at the end of the rehabilitation process. We therefore believe that an adequate, effective communication between the people making up the health care team and the patient's social and family network is the foundation of the rehabilitation process. It is precisely on this foundation that the individual's care and assistance need to be assembled.

Clinical guidelines for the prevention and treatment of osteoporosis: summary statements and recommendations from the Italian Society for Orthopaedics and Traumatology

BACKGROUND

The Italian Society for Orthopaedics and Traumatology conceived this guidance-which is primarily addressed to Italian orthopedic surgeons, but should also prove useful to other bone specialists and to general practitioners-in order to improve the diagnosis, prevention, and treatment of osteoporosis and its consequences.

MATERIALS AND METHODS

Literature reviews by a multidisciplinary team.

RESULTS

The following topics are covered: the role of instrumental, metabolic, and genetic evaluations in the diagnosis of osteoporosis; appraisal of the risk of fracture and thresholds for intervention; general strategies for the prevention and treatment of osteoporosis (primary and secondary prevention); the pharmacologic treatment of osteoporosis; the setting and implementation of fracture liaison services for tertiary prevention. Grade A, B, and C recommendations are provided based on the main levels of evidence (1-3). Toolboxes for everyday clinical practice are provided.

CONCLUSIONS

The first up-to-date Italian guidelines for the primary, secondary, and tertiary prevention of osteoporosis and osteoporotic fractures are presented.

Prescription of anti-osteoporosis medications after hospitalization for hip fracture: a multicentre Italian survey

PURPOSE

Literature data indicate that the proportion of patients with recent hip fracture who receive a prescription for anti-osteoporotic drugs is low and does not seem to increase over time. This study aimed to obtain data on the prescription for anti-osteoporotic drugs in Italian patients discharged after a recent hip fracture and to assess which variables could have influenced the decision for prescribing osteoporosis medication.

METHODS

A total of four Italian centres located in four different geographical areas (Siena, Verona, Naples and Palermo) participated in this retrospective study. In each centre, experienced clinicians gathered the data of up to 200 consecutive patients discharged after a recent low-trauma hip fracture. The analysis was carried out on 697 patients (540 women and 157 men; mean age 81.9 ± 8.6 years).

RESULTS

The percentage of patients who were receiving any type of treatment for osteoporosis before the hip fracture was 8.8% (ranging from 2.4% in Naples to 17.4% in Verona). After the index hip fracture, only 23.2% of patients (namely 10.5% of men and 27.2% of women) received prescription for any pharmacological treatments for osteoporosis. Both female gender and previous use of medications for osteoporosis were positively associated with the likelihood of receiving prescription for anti-osteoporotic treatment at discharge.

CONCLUSIONS

This study showed that less than 25% of the elderly Italian patients discharged after a hip fracture received a prescription for any type of treatment for osteoporosis and highlights the urgent need for implementing new strategies in the management of hip fracture patients.

Impact of sleep on osteoporosis: sleep quality is associated with bone stiffness index

OBJECTIVE

The aim of the present study was to investigate the impact of sleep on osteoporosis.

METHODS

The study used a baseline examination of the Hiroshima Sleep and Healthcare study, which was a cross-sectional and cohort study that addressed the association of sleep habits with lifestyle-related diseases. A total of 1032 participants (25-85 years of age) who underwent health examinations were included. Sleep habits, including its timing (bed time), quantity (time in bed [TIB]), and quality, were assessed using the Pittsburgh Sleep Quality Index (PSQI). The bone stiffness index (SI), a marker of osteoporosis, was measured using quantitative ultrasound systems.

RESULTS

Bed time (r = 0.065, p <0.05), TIB (r = -0.064, p <0.05), and global PSQI score (r = -0.126, p <0.0001) significantly correlated with SI. Multiple regression analyses revealed that after adjusting for age, sex, body mass index, smoking, and alcohol intake, the global PSQI score (β = -0.053, p <0.05) was significantly associated with SI, whereas bed time or TIB was not. Among each component of PSQI, sleep disturbances (β = -0.084, p <0.005) were significantly associated with SI.

CONCLUSION

Poor sleep quality may be associated with osteoporosis. In particular, increased sleep disturbances may be a key factor in the association between poor sleep quality and osteoporosis.

Management of atypical femoral fracture: a scoping review and comprehensive algorithm

BACKGROUND

Atypical femoral fractures (AFF) are a rare type of femoral stress fracture recently described, potentially associated with prolonged bisphosphonate therapy. Evidence-based recommendations regarding diagnosis and management of these fractures are scarce. The purpose of this study is to propose an algorithm for the diagnosis and management of AFF.

METHODS

We performed a PubMed search of the last ten years using the keywords "atypical femoral fractures" and identified further articles through an evaluation of the publications cited in these articles. Relevant studies were included by agreement between researchers, depending on their specialization. Pertinent points of debate were discussed based on the available literature, allowing for consensus regarding the proposed management algorithm.

RESULTS

Using a systematic approach we performed a scoping review that included a total of 137 articles.

CONCLUSIONS

A practical guide for diagnosis and management of AFF based on the current concepts is proposed. In spite of the impressive large volume of published literature available since AFF were initially identified, the level of evidence is mostly poor, in particular regarding treatment choice. Therefore, further studies are required.

Direct and indirect costs of surgically treated pelvic fractures

INTRODUCTION

Pelvic fractures requiring surgical fixation are rare injuries but present a great societal impact in terms of disability, as well as economic resources. In the literature, there is no description of these costs. Main aim of this study is to describe the direct and indirect costs of these fractures. Secondary aims were to test if the type of fracture (pelvic ring injury or acetabular fracture) influences these costs (hospitalization, consultation, medication, physiotherapy sessions, job absenteeism).

MATERIALS AND METHODS

We performed a retrospective study on patients with surgically treated acetabular fractures or pelvic ring injuries. Medical records were reviewed in terms of demographic data, follow-up, diagnosis (according to Letournel and Tile classifications for acetabular and pelvic fractures, respectively) and type of surgical treatment. Patients were interviewed about hospitalization length, consultations after discharge, medications, physiotherapy sessions and absenteeism.

RESULTS

The study comprised 203 patients, with a mean age of 49.1 ± 15.6 years, who had undergone surgery for an acetabular fracture or pelvic ring injury. The median treatment costs were 29.425 Euros per patient. Sixty percent of the total costs were attributed to health-related work absence. Median costs (in Euros) were 2.767 for hospitalization from trauma to definitive surgery, 4.530 for surgery, 3.018 for hospitalization in the surgical unit, 1.693 for hospitalization in the rehabilitation unit, 1.920 for physiotherapy after discharge and 402 for consultations after discharge. Total costs for treating pelvic ring injuries were higher than for acetabular fractures, mainly due to the significant higher costs of pelvic injuries regarding hospitalization from trauma to definitive surgery (p < 0.001) and hospitalization in the surgical unit (p = 0.008).

CONCLUSIONS

Pelvic fractures are associated with both high direct costs and substantial productivity loss.

Proximal femur geometry assessed by hip structural analysis in hip fracture in women

INTRODUCTION

In the pathogenesis of hip fracture, proximal femur geometry plays a key role as well as decreased bone density. The hip structural analysis (HSA) processes dual energy X-ray absorptiometry (DXA) images containing information on the geometry closely related to the strength of the proximal femur. The objective of this study was to investigate bone mineral density (BMD) and mechanical properties of the proximal femur in a group of women with a previous contralateral hip fragility fracture compared to women without history of hip fracture.

MATERIALS AND METHODS

In a population of postmenopausal women, we evaluated bone density by DXA and bone geometry using the HSA parameters (femoral strength index, cross-sectional moment of inertia, cross-sectional area, section modulus, and buckling ratio) including hip axis length (HAL) and neck shaft angle.

RESULTS

Of a total of 62 postmenopausal women, twenty-six with a history of hip fracture had a mean femoral neck BMD significantly lower in comparison with 36 women in the control group (0.703 versus 0.768 g/cm(2), p = 0.0347). There was a statistically significant difference between groups also for HAL (106.75 mm in fracture group versus 100.93 mm in control group, p = 0.0015).

DISCUSSION AND CONCLUSIONS

Our results demonstrated that all the geometrical parameters resulted worst into the group of patients with history of hip fracture, even though only the HAL was significantly lower in control subjects. In our opinion HSA is useful to characterize the risk of hip fracture in postmenopausal women, providing additional data on the spatial distribution of bone mass strongly related to bone strength.

Is the Patellar Pubic Percussion Test useful to diagnose only femur fractures or something else? Two case reports

In the literature, the utility of the Patellar Pubic Percussion Test (PPPT) to diagnose occult fractures of the femur is well described. However, up to now there are no studies demonstrating the efficacy of this test in recognizing fractures of the pelvis. In this two case report a positive PPPT allowed the therapist to recognize clinical conditions requiring caution, protecting patients from a potentially unsuitable treatment. Both patients had a negative pelvis and femur x-ray after a fall, but the clinical findings and a positive PPPT lead the physiotherapist to suggest further examinations. In these two cases the PPPT seemed to be a useful diagnostic tool to identify periacetabular, ileo-pubic and ischio-pubic ramus fractures. These findings suggest that PPPT could be positive even for a bone lesion in any of the transit points of the vibration, from the patella to the pubic symphysis.

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.

Fracture prevention service to bridge the osteoporosis care gap

BACKGROUND

A care gap exists between the health care needs of older persons with fragility fractures and the therapeutic answers they receive. The Fracture Prevention Service (FPS), a tailored in-hospital model of care, may effectively bridge the osteoporosis care gap for hip-fractured older persons. The purpose of this study was to evaluate the efficacy of the FPS in targeting persons at high risk of future fracture and to improve their adherence to treatment.

METHODS

This was a prospective observational study conducted in a teaching hospital with traumatology and geriatric units, and had a pre-intervention and post-intervention phase. The records of 172 participants were evaluated in the pre-intervention phase, while data from 210 participants were gathered in the post-intervention phase. All participants underwent telephone follow-up at 12 months after hospital discharge. The participants were patients aged ≥65 years admitted to the orthopedic acute ward who underwent surgical repair of a proximal femoral fracture. A multidisciplinary integrated model of care was established. Dedicated pathways were implemented in clinical practice to optimize the identification of high-risk persons, improve their evaluation through bone mineral density testing and blood examinations, and initiate an appropriate treatment for secondary prevention of falls and fragility fractures.

RESULTS

Compared with the pre-intervention phase, more hip-fractured persons received bone mineral density testing (47.62% versus 14.53%, P<0.0001), specific pharmacological treatments (48.51% versus 17.16%, P<0.0001), and an appointment for evaluation at a fall and fracture clinic (52.48% versus 2.37%, P<0.0001) in the post-intervention phase. Independent of some confounders, implementation of the FPS was positively associated with recommendations for secondary fracture prevention at discharge (P<0.0001) and with 1-year adherence to pharmacological treatment (P<0.0001).

CONCLUSION

The FPS is an effective multidisciplinary integrated model of care to optimize identification of older persons at highest risk for fragility fracture, to improve their clinical management, and to increase adherence to prescriptions.

Altered neutrophil functions in elderly patients during a 6-month follow-up period after a hip fracture

BACKGROUND

Fracture of the hip (HF) is a significant cause of morbidity and mortality in elderly individuals. HF is an acute stress that triggers a state of inflammation which may affect immune responses and physical recovery.

METHODS

Longitudinal study of the impact of HF on the functions of polymorphonuclear neutrophils (PMNs) in elderly subjects. Data were recorded prior to surgery, 6weeks and 6months later.

RESULTS

PMN functions were severely impaired shortly after HF (chemotaxis, phagocytosis, superoxide production) but there was a time-related recovery of some PMN functions (chemotaxis, phagocytosis) over time, except in the case of superoxide production. Whereas FcγRII (CD32) expression remained unchanged, FcγRIII (CD16) increased from low values before surgery to levels of controls 6months post-surgery. This was also the case for the C5a complement receptor and CD11b. TLR2 and TLR4 expressions were unchanged. Cytokine and chemokine secretions by stimulated PMN were altered. TNFα and IL-10 secretions were increased following HF but IL-8 secretion was decreased. Impaired PMN functions prior to surgery were related to alterations in PI3K and NF-κB signaling pathways. Recovery of these functions paralleled increased PI3K activity, although superoxide production remained low. Sustained activation of the NF-κB pathway by TNFα has been reported to involve upregulation of IKKβ kinase activity. Activated IKKβ kinase inhibits ERK1/2 and results in concomitant downstream inhibition of NADPH oxidase complex which can account for sustained impaired production of ROS in HF patients.

CONCLUSION

Our data showed that the stress caused by HF negatively affects initial PMN responses shortly after the event and that may negatively influence clinical outcomes such as resolving long-term inflammation and recovery, as well as explaining susceptibility to opportunistic infections.

Intra- and extra-capsular hip fractures in the elderly: Two different pathologies?

OBJECTIVES

To compare intracapsular (IC) and extracapsular (EC) hip fractures (HIF) in elderly patients in order to determine if they are different pathologies.

SUBJECTS AND METHODS

Longitudinal, observational, descriptive, analytical prospective design, using a non-probabilistic sample from a full sample collection with 647 subjects (male and female), of 60 or more years old, admitted with HIF to the Department of Orthopedics and Traumatology of the Hospital, between January 1, 2010 and December 31, 2012. Follow-up was for 1 year post HIF. Socio-demographic, etiological, developmental, therapeutic and prognostic variables are compared.

RESULTS

This is the first study on this subject with Latin American population. EC HIF incidence was superior to IC, contrary to that published in European/American populations. There are significant differences in etiological variables (χ(2)=6.34, p<0.042), with traumatic etiology in EC and non-traumatic in IC. There are also differences in therapeutic interventions performed (osteosynthesis for EC, arthroplasty for IC), with the decision on not to operate being lower in IC (both p<0.0000). The variables associated with the decision on not to perform surgery are age, etiology and postoperative mortality.

DISCUSSION

The results are similar to other studies, adding the IC association with non-traumatic origin, in particular the trend of statistical association between IC and non-primary osteoporotic pathology (neoplasms, renal osteodystrophy, primary hyperparathyroidism). A further analysis was performed on the differences between Latin American and European/American populations in the incidence of either type of HIF. There are important etiological and therapeutic differences between IC and EC HIF; therefore it would be advisable to consider them as distinct disease entities.

Single shot spinal anesthesia with very low hyperbaric bupivacaine dose (3.75 mg) for hip fracture repair surgery in the elderly. A randomized, double blinded study

PURPOSE

Single shot spinal anesthesia is used worldwide for hip fracture repair surgery in the elderly. Arterial hypotension is a frequent adverse effect. We hypothesized that lowering local anesthetics dose could decrease the incidence of arterial hypotension, while maintaining quality of surgical anesthesia.

METHODS

In a randomized double blinded study, 66 patients over the age of 65 years, with hip fracture needing surgical repair, were assigned to B0.5 group 7.5mg hyperbaric bupivacaine 5mg/ml (control group), and B0.25 group 3.75mg hyperbaric bupivacaine 2.5mg/ml (study group). Sensory and motor block level, and hemodynamic parameters including blood presure, heart rate and vasopressor dose administration were registered, along with rescue anesthesia needs, the feasibility of surgery, its duration, and regression time of sensory anesthesia to T12.

RESULTS

After exclusions, 61 patients were included in the final analysis. Arterial hypotension incidence was lower in the B0.25 group (at the 5, 10, and 15min determinations), and a lower amount of vasopressor drugs was needed (mean accumulated ephedrine dose 1.6mg vs. 8.7mg in the B0.5 group, p<0.002). Sensory block regression time to T12 was shorter in the B0.25 group, mean 78.6±23.6 (95% CI 51.7-110.2)min vs. 125.5±37.9 (95% CI 101.7-169.4)min in the B0.5 group, p=0.033. All but one patient in the B0.25 group were operated on under the anesthetic procedure first intended. No rescue anesthesia was needed.

CONCLUSION

Lowering bupivacaine dose for single shot spinal anesthesia for hip fracture repair surgery in elderly patients was effective in decreasing the occurrence of arterial hypotension and vasopressor use, while intraoperative quality remained.

The management of hip fracture in the older population. Joint position statement by Gruppo Italiano Ortogeriatria (GIOG)

This document is a Joint Position Statement by Gruppo Italiano di OrtoGeriatria (GIOG) supported by Società Italiana di Gerontologia e Geriatria (SIGG), and Associazione Italiana Psicogeriatria (AIP) on management of hip fracture older patients. Orthogeriatric care is at present the best model of care to improve results in older patients after hip fracture. The implementation of orthogeriatric model of care, based on the collaboration between orthopaedic surgeons and geriatricians, must take into account the local availability of resources and facilities and should be integrated into the local context. At the same time the programme must be based on the best available evidences and planned following accepted quality standards that ensure the efficacy of the intervention. The position paper focused on eight quality standards for the management of hip fracture older patients in orthogeriatric model of care. The GIOG promotes the development of a clinic database with the aim of obtaining a qualitative improvement in the management of hip fracture.

Gotfried percutaneous compression plating (PCCP) versus dynamic hip screw (DHS) in hip fractures: blood loss and 1-year mortality

BACKGROUND

Intertrochanteric fractures are among the most common fracture in elderly and are correlated with an average 1-year mortality of 25 %. Increased mortality after hip fracture could be related to blood loss and comorbidities.

AIMS

We compared two groups of patients treated with percutaneous compression plating (PCCP) and dynamic hip screw (DHS) with the hypothesis that treatment with PCCP can reduce blood loss and 1-year mortality. We furthermore investigated the role of several surgical-related and patient-related factors on mortality of all the enrolled patients.

METHODS

We performed a comparative retrospective study of 280 patients with type 31A1 or 31A2 hip fractures treated in our department from January 2004 to May 2008. Exclusion criteria were age <60 years, multiple injuries and pathological fractures. A total of 194 patients were treated with DHS, and 86 patients were treated with PCCP.

RESULTS

No statistical differences were found in term of blood loss, blood transfusion and 1-year mortality between the two groups, whereas we found a significant incidence of gender, age, American Society of Anaesthesiologists score and preoperative haemoglobin on mortality.

DISCUSSION

Both plates seem to be comparable in terms of blood loss and blood transfusion rate, and mortality was rather correlated with some patient-related factors reflecting the global health status.

CONCLUSION

Emerging mortality in this kind of patient should encourage us to improve preventative orthogeriatric health care.

Single shot spinal anaesthesia with hypobaric bupivacaine for hip fracture repair surgery in the elderly. Randomized, double blinded comparison of 3.75 mg vs. 7.5 mg

BACKGROUND

Arterial hypotension is the most frequent adverse effect of subarachnoid anaesthesia in the elderly sustaining a femoral proximal fracture. Decreasing the local anaesthetic dose reduces the incidence of hypotension but shortens sensory block duration that could be insufficient in some surgical procedures. Sensory block duration could be prolonged using hypobaric local anaesthetics. We evaluated whether low hypobaric bupivacaine doses were adequate for this type of surgery while maintaining the haemodynamic stability.

METHODS

A prospective, randomized, double blinded study was designed. Patients over 65 years old, sustaining traumatic hip fracture, were assigned to one of two groups: B0.5 group, hypobaric bupivacaine 7.5mg 5mg/ml (control group), and B0.25 group, hypobaric bupivacaine 3.75 mg 2.5mg/ml (study group). After subarachnoid injection, sensory level and motor blockade degree were registered, as were blood pressure, and heart rate at basal time and at 2, 5, 10, 15, 20 and 30 min after injection. The doses of vasopressor needed were registered as well. Surgical conditions and the duration of the surgical procedure-whether rescue analgesia or anaesthesia was needed-and sensory level regression to T12, were registered as well.

RESULTS

Sixty four patients was the calculated sample size. The study was stopped in an interim analysis because an elevated number of patients in the B0.25 group needed iv rescue anaesthesia. In the analyzed cases, blood pressure was significantly lower in the B0.5 group at the 15 and 30 min measurements. Vasopressor drugs needs were similar between groups [ephedrine accumulated mean (SD) doses 11.4 (5.2) mg vs. 9.1 (2.7) mg, p=0.045)]. Sensory block regression to T12 was faster in the B0.25 group, [(mean (SD) 68.2 (29.0) min vs. 112.8 (17.3) min in the B0.5 group, p<0.05]. Five out of 19 patients in the B0.25 group needed intravenous anaesthesia rescue before surgery started.

CONCLUSION

Lowering hypobaric bupivacaine dose to 3.75 mg in subarachnoid anaesthesia for hip fracture repair surgery in elderly patients decrease intraoperative blood pressure, but in an important number of patients intravenous anaesthesia rescue was needed and preclude recommendation.

Association of ABO blood group with fracture pattern and mortality in hip fracture patients

INTRODUCTION

The mechanism of falling has been proposed as the exclusive explanation for hip fracture pattern. Evidence exists that other genetic factors also influence proximal femoral fracture configuration. The ABO blood group serotype has been associated with other pathologies but any role in hip fracture has yet to be definitively characterised.

METHODS

Our National Hip Fracture Database was interrogated over a four-year period. All patients had their blood group retrieved, and this was compared with hip fracture pattern and mortality rates. Confounding factors were accounted for using logistic regression and the Cox proportional hazards model.

RESULTS

A total of 2,987 consecutive patients presented to our institution. Those with blood group A were significantly more likely to sustain intracapsular fractures than 'non-A' individuals (p=0.009). The blood group distribution of patients with intracapsular fractures was identical to that of the national population of England. However, blood group A was less common in patients with intertrochanteric fractures than in the general population (p=0.0002). Even after correction for age and sex, blood group A was associated with a decrease in the odds of suffering an intertrochanteric fracture to 80% (p=0.002). Blood group A had inferior survivorship correcting for age, sex and hip fracture pattern (hazard ratio: 1.14, p=0.035). This may be due to associated increased prevalence of co-morbid disease in this cohort.

CONCLUSIONS

Blood group is an independent predictor of hip fracture pattern, with group A patients more likely to sustain an intracapsular fracture and non-A individuals more likely to sustain an intertrochanteric fracture. The determinants of fracture pattern are likely to be related to complex interactions at a molecular level based on genetic susceptibility. The mechanism of fall may not be the only aetiological determinant of proximal femoral fracture configuration.

Diabetes and Obesity as Independent Risk Factors for Osteoporosis in Postmenopausal Women: A Population Study

We aimed to analyze bone mineralization and the effect of different risk factors for osteoporosis in postmenopausal women. We studied 2,756 postmenopausal subjects out of ≥10,000 records from the ROIS registry in the frame of the PROF Project, a population study carried out in Salento (Taranto, Brindisi, Lecce) from 2009 to 2012. All subjects were assessed by phalangeal Quantitative Ultrasound (QUS) to evaluate their bone mineralization (assessed by Amplitude Dependent Speed of Sound, AD-SoS) and the association between demineralization and the presence of other conditions or risk factors. Mean age was 64±9.5 years and mean BMI was 28.7±3.5 Kg/m2. Pearson correlation analyses revealed a negative association between bone mineralization (AD-SoS) and BMI (P<0.001). By using multivariate logistic regression analysis, we observed significant values of Odds Ratios of osteoporosis (adjusted for age, physical activity and the use of drugs known to increase the risk of fractures) in subjects with diabetes and obesity: 1.39 (CI: 1,05–1,83) and 1.46 (CI: 1.20–1.78), respectively. A statistically significant linear trend of higher Odds Ratios of osteoporosis was found for increasing values of BMI. The percent change in the odds of vertebral fractures per single SD decrease of AD-SoS was 47% (P<0.001). Diabetes and obesity in postmenopausal women are likely to represent independent risk factors for osteoporosis. Phalangeal QUS showed a good power of predictivity in identifying subjects with vertebral fractures.

Results of a model of secondary prevention for osteoporotic fracture coordinated by rheumatology and focused on the nurse and primary care physicians

OBJECTIVE

To assess the influence of the implementation of a program for secondary prevention of osteoporotic fractures on prescribing bisphosphonates and persistent short-term treatment.

PATIENTS AND METHODS

Patients >50 years with fragility fracture attended in the emergency department were enrolled in an observational study. The program consisted of: 1) training of primary care physicians, 2) baseline visit: questionnaire on osteoporosis, bone densitometry and patient education, 3) patient referral to primary care, except those with multiple fractures or requiring special study or therapy, who were referred to a specialist, and 4) follow-up by checking prescriptions in electronic records, and a telephone survey. The outcome variable was the percentage of patients who, on having been prescribed bisphosphonates, still adhered to the treatment at 3 months.

RESULTS

Of the 532 patients with inclusion criteria, 202 (39%) refused to participate. Those who refused to take part had a higher mean age (P<.01) and a higher frequency of hip fracture (P<.01) compared with patients who did participate. A total of 330 patients were included for intervention, with a mean age of 71 years, and 254(77%) were female. An antiresorptive was being used by 45 patients (13%) at baseline. After the baseline visit 223 patients (67%) were recommended a bisphosphonate. In the follow-up at 3 months 78% of patients who had been prescribed bisphosphonate were still receiving treatment.

CONCLUSIONS

We present a multidisciplinary program for secondary prevention of fractures coordinated by rheumatology in which the number of patients who were receiving bisphosphonate at 3 months increased by four times compared to baseline visit.

The contribution of cortical and trabecular tissues to bone strength: insights from denosumab studies

All materials undergo an aging process which is characterized essentially by changes of the rigidity (stiffness), of the ability to absorb the stresses (toughness) and then ultimately in the mechanical resistance (strength). Both cortical and trabecular bone undergo a continuous process of structural remodeling with the main aim to preserve their biomechanical properties. An imbalance in this process, which promotes bone resorption, results in a quantitative loss of bone tissue and in a qualitative alteration of the skeletal microarchitecture, as you can see in osteoporosis, rheumatoid arthritis or bone metastases. Cortical component has a prominent role on strength therefore loss of cortical bone that is prevalent in elderly may explain the higher frequency of fractures of bones composed mainly of cortical bone such as the proximal femur. Remodeling inhibition with denosumab improved structural strength without altering material properties, that can be primarily explained by the combined effects of increased trabecular and cortical bone mass, and reductions in trabecular eroded surfaces and particularly cortical porosity. Denosumab for its mechanism of action and pharmacokinetics results in a significant, early and continued increase in BMD with enhanced bone strength improving both cortical and trabecular bone.
