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

Incidence of fragility hip fracture across the Asia-pacific region: A systematic review

PURPOSE

This systematic review aimed to update fragility hip fracture incidences in the Asia Pacific, and compare rates between countries/regions.

METHOD

A systematic search was conducted in four electronic databases. Studies reporting data between 2010 and 2023 on the geographical incidences of hip fractures in individuals aged ≥50 were included. Exclusion criteria were studies reporting solely on high-trauma, atypical, or periprosthetic fractures. We calculated the crude incidence, age- and sex-standardised incidence, and the female-to-male ratio. The systematic review was registered with PROSPERO (CRD42020162518).

RESULTS

Thirty-eight studies were included across nine countries/regions (out of 41 countries/regions). The crude hip fracture incidence ranged from 89 to 341 per 100,000 people aged ≥50, with the highest observed in Australia, Taiwan, and Japan. Age- and sex-standardised rates ranged between 90 and 318 per 100,000 population and were highest in Korea and Japan. Temporal decreases in standardised rates were observed in Korea, China, and Japan. The female-to-male ratio was highest in Japan and lowest in China.

CONCLUSION

Fragility hip fracture incidence varied substantially within the Asia-Pacific region. This observation may reflect actual incidence differences or stem from varying research methods and healthcare recording systems. Future research should use consistent measurement approaches to enhance international comparisons and service planning.

Epidemiology of hip fractures in Thailand

This retrospective study examining hip fracture incidence, hip fracture trends, and the annual hospitalization costs for hip fractures in a population aged 50 years and older within the Universal Health Coverage System revealed that the incidence of hip fractures and the annual hospitalization costs for hip fractures increased significantly from 2013 to 2022.

PURPOSE

To examine the annual incidence of hip fractures over 10 years (2013-2022), hip fracture trends, and the annual hospitalization costs for hip fractures in a population aged 50 years and older within the Universal Health Coverage System.

METHODS

A retrospective study was conducted. Hip fracture hospitalizations were identified using ICD-10. Data on the number of hip fracture hospitalizations, population aged ≥ 50 years, and hospitalization costs were obtained. The primary outcome was the annual incidence of hip fractures. The secondary outcomes were hip fracture incidence by 5-year age group, the annual hospitalization costs for hip fractures, and the number of hip fractures in 6 regions of Thailand.

RESULTS

The hip fracture incidence increased annually from 2013-2019 and then plateaued from 2019-2022, with the crude incidence (per 100,000 population) increasing from 112.7 in 2013 to 146.7 in 2019 and 146.9 in 2022. The age-standardized incidence (per 100,000 population) increased from 116.3 in 2013 to 145.1 in 2019 and remained at 140.7 in 2022. Increases in the crude incidence were observed in both sexes (34% in females and 21% in males; p < 0.05). The annual hospitalization costs for hip fractures increased 2.5-fold, from 17.3 million USD in 2013 to 42.8 million USD in 2022 (p < 0.001). The number of hip fractures increased in all six regions of Thailand across the 10-year study period.

CONCLUSION

Osteoporotic hip fractures are a significant health concern in Thailand. The incidence and the annual hospitalization costs for hip fractures increased significantly from 2013 to 2022.

Global burden of hip fracture: The Global Burden of Disease Study

This study is the first to measure global burden of hip fracture in patients aged 55 years and older across 204 countries and territories from 1990 to 2019. Our study further proved that the global burden of hip fracture is still large. Hip fractures among males are perhaps underestimated, and older adults should be given more attention.

PURPOSE

Hip fracture is a tremendous universal public health challenge, but no updated comprehensive and comparable assessment of hip fracture incidence and burden exists for most of the world in older adults.

METHODS

Using data from the Global Burden of Diseases (GBD) 2019, we estimated the number and rates of the incidence, prevalence, and years lived with disability (YLD) of hip fracture across 204 countries and territories in patients aged 55 years and older from 1990 to 2019.

RESULTS

In 2019, the incidence, prevalence, and YLDs rates of hip fracture in patients aged 55 years and older were 681.35 (95% UI 508.36-892.27) per 100000 population, 1191.39 (95% UI 1083.80-1301.52) per 100000 population, and 130.78 (95% UI 92.26-175.30) per 100000 population. During the three decades, the incidence among people aged below 60 years showed a downward trend, whereas it showed a rapid upward trend among older adults. All the numbers and rates of hip fractures among females were higher than those among males and increased with age, with the highest number and rate in the highest age group. Notably, the male to female ratio of the incidence for people aged over 55 years increased from 0.577 in 1990 to 0.612 in 2019. Falls were the leading cause among both sexes and in all age groups.

CONCLUSIONS

The incidence and the number of hip fractures among patients aged 55 years and older increased over the past three decades, indicating that the global burden of hip fracture is still large. Hip fractures among males are perhaps underestimated, and older adults should be given more attention.

The burden of fracture in China from 1990 to 2019

PURPOSE

Osteoporosis is one of the most common clinical problems among the elderly population. China is one of the countries most threatened by osteoporosis and fragility fracture, because of its large population and aging population trends during recent decades. We aimed to estimate the disease burden of fracture from 1990 to 2019 in China.

METHODS

We performed a secondary analysis of fractures using detailed information for China from the Global Burden of Disease Study 2019. Fracture incidence and prevalence, rate of years lost to disability from fractures, and term secular trends in China from 1990 to 2019 were compared by sex, age, cause, and nature of fracture.

RESULTS

The numbers for incidence and prevalence of fracture and years lived with disability (YLDs) from fractures in China increased from 12.54 million, 28.35 million, and 1.71 million in 1990 to 21.27 million, 67.85 million, and 3.79 million in 2019, respectively, increases of 70%, 139%, and 122%, respectively. In 2019, falls was the leading cause of fractures, with an age-standardized incidence rate (ASIR) of 762 per 100 000 (95% uncertainty interval [UI] 629-906), an age-standardized prevalence rate (ASPR) of 1863 per 100 000 (95% UI 1663-2094), and an age-standardized YLD rate (ASYR) of 103 per 100 000 (95% UI 69-147). Fall-associated deaths and disability-adjusted life-years (DALYs) from low bone mineral density increased greatly during the most recent three decades. Fracture of patella, tibia or fibula, and ankle were the most frequent fracture types, with an ASYR of 116 per 100 000 (95% UI 75-169). Hip fracture had more incident cases in adults ≥ 60 years old, and was more frequent for females.

CONCLUSIONS

The burden from fractures has increased significantly since 1990 in China. Falls and road injuries are the main causes of the increase. The fall-associated health burden from osteoporosis needs to be prioritized, with longer-term commitment to its reduction required.

Osteoporosis care after hip fracture: Observation from national health insurance database and fracture liaison services

BACKGROUND

The objective of this research was to report the trend of osteoporosis care after hip fractures from usual care (UC) and to compare the quality of care with those who received fracture liaison services (FLSs).

METHODS

Data on osteoporosis care for patients with hip fracture were acquired from the National Health Insurance claims (UC group), and surveys from FLS programs (FLS group). A total of 183,300 patients receiving UC and 3010 patients receiving FLS were studied. For the two groups, common osteoporosis care indicators, such as bone mineral density (BMD) testing rate, antiosteoporosis medication commencement rate, and adherence rate were described.

RESULTS

There were 2488 participants (82.7%) in the FLS group who completed Dual-energy X-ray absorptiometry (DXA) in 8 weeks, 155 (5.1%) who finished it between 8 weeks and 1 year. Even in 2018, when the DXA completion rate was at its highest, the completion rate in the UC group was only 23.5%. In terms of medication commencement, 2372 FLS patients (78.8%) received treatment within 3 months. Only 24.9% of the UC patients received antiosteoporosis medication within 3 months. Furthermore, antiosteoporosis medication adherence rate was 92.2% after 1 year and 83.9% after 2 years in the FLS group, but these were only 66.5% and 42.7%, respectively, in the UC group.

CONCLUSION

Patients who received FLS had more timely BMD exams, antiosteoporosis medication treatment, and higher adherence to antiosteoporosis therapy than those who received UC. The discrepancy in rates of continuing treatment became more significant over time between both groups.

Epidemiology and clinical impact of osteoporosis in Taiwan: A 12-year trend of a nationwide population-based study

BACKGROUND

Osteoporosis increases the fracture and mortality risk of patients and has a higher disease burden than some cancers. Therefore, global concerns regarding the prevention and treatment of osteoporosis have been raised. However, fast-aging Taiwan lacks national epidemiological data on osteoporosis in recent years. We aimed to establish and update epidemiological data on osteoporosis by analyzing national data from 2008 to 2019.

METHODS

We estimated the prevalence and incidence of osteoporosis in patients aged ≥50 years based on claims data from Taiwan's National Health Insurance database from 2008 to 2019. We also analyzed the key parameters of fracture care (anti-osteoporosis medication use, bone mineral density examination rate, and length of hospital stay) to understand the secular trend of management and related clinical outcomes (imminent refracture rate and mortality).

RESULTS

The number of prevalent osteoporosis increased from 2008 to 2015 and remained constant until 2019; however, the age-standardized prevalence and incidence rates declined from 2008 to 2019 (3.77%-2.91% and 2.08%-1.02%, respectively). The overall incidence rates of hip and spine fractures decreased significantly by 34% and 27%, respectively. For patients with hip and spine fractures, the immanent refracture rates were 8.5% and 12.9% and the 1-year mortality rate remained stable at approximately 15% and 6%, respectively.

CONCLUSION

The age-standardized prevalence and incidence rates decreased remarkably from 2008 to 2019, while the number of prevalent osteoporosis remained steady. Patients with hip fractures encountered a high 1-year mortality rate, while the risk of imminent refracture was notable for patients with spine fractures.

Clinical practice guidelines for the prevention and treatment of osteoporosis in Taiwan: 2022 update

Osteoporosis greatly increases the risk of fractures. Osteoporotic fractures negatively impact quality of life, increase the burden of care, and increase mortality. Taiwan is an area with a high prevalence of osteoporosis. This updated summary of guidelines has been developed by experts of the Taiwan Osteoporosis Association with the intention of reducing the risks of osteoporotic fractures and improving the quality of care for patients with osteoporosis. The updated guidelines compile the latest evidence to provide clinicians and other healthcare professionals with practical recommendations for the prevention, diagnosis, and management of osteoporosis under clinical settings in Taiwan.

Epidemiology and Management of Proximal Femoral Fractures in Italy between 2001 and 2016 in Older Adults: Analysis of the National Discharge Registry

This study aims to determine the annual incidence of proximal femoral fractures in Italy in the period between 2001 and 2016 among older adults, and to describe the trends in the clinical management of these cases. Data were retrieved from the National Hospital Discharge records issued by the Italian Ministry of Health and from the Italian Institute for Statistics. The number of hospitalizations increased between 2001 and 2016, while the age-adjusted yearly incidence decreased from 832.2 per 100,000 individuals to 706.2. The median age was 83 years (IQR 78-88) with a large majority of females (76.6%). The type of fracture varied with age in female subjects, with older women more frequently reporting pertrochanteric fractures. Therapeutic strategies for the different types of fracture depended on patients' age. During the study years, improvements in fracture classification and management strategies were observed, with a clear decreasing trend for non-operative solutions. In conclusion, the number of proximal femur fractures in older adults is growing, even if at a lower rate compared to population aging. The Italian surgical practice changed during the study period towards the implementation of the most recent guidelines.

Multipronged Programmatic Strategy for Preventing Secondary Fracture and Facilitating Functional Recovery in Older Patients after Hip Fractures: Our Experience in Taipei Municipal Wanfang Hospital

Background and Objectives: The study assessed the effectiveness of a fracture liaison service (FLS) after 1 year of implementation in improving the outcomes of hip fracture surgery in older adult patients at Taipei Municipal Wanfang Hospital. Materials and Methods: The Wanfang hospital’s FLS program was implemented using a multipronged programmatic strategy. The aims were to encourage the screening and treatment of osteoporosis and sarcopenia, to take a stratified care approach for patients with a high risk of poor postoperative outcomes, and to offer home visits for the assessment of environmental hazards of falling, and to improve the patient’s adherence to osteoporosis treatment. The clinical data of 117 and 110 patients before and after FLS commencement, respectively, were collected from a local hip fracture registry; the data were analyzed to determine the outcomes 1 year after hip fracture surgery in terms of refracture, mortality, and activities of daily living. Results: The implementation of our FLS significantly increased the osteoporosis treatment rate after hip fracture surgery from 22.8% to 72.3%, significantly decreased the 1-year refracture rate from 11.8% to 4.9%, non-significantly decreased 1-year mortality from 17.9% to 11.8%, and improved functional outcomes 1 year after hip fracture surgery. Conclusions: Implementation of our FLS using the multipronged programmatic strategy effectively improved the outcomes and care quality after hip fracture surgery in the older adult population, offering a successful example as a valuable reference for establishing FLS to improve the outcomes in vulnerable older adults.

Hyperuricemia and Its Association with Osteoporosis in a Large Asian Cohort

In this paper, we aimed to examine the protective role of hyperuricemia in the prevalence of osteoporosis in a large Asian cohort. A total of 119,037 participants from 29 recruitment centers in Taiwan were enrolled onto our study. Participants with serum uric acid greater than 7.0 mg/dL in men and 6.0 mg/dL in women were classified as the hyperuricemia group whereas the others were the control group. The mean age of all participants was 50; there were 23,114 subjects (19%) with hyperuricemia. Osteoporosis was observed in 8243 (9%) and 1871 (8%) participants in the control and hyperuricemia groups, respectively. After adjusting for confounders, a lower risk of osteoporosis was found in the hyperuricemia group compared with the control group (odds ratio, 0.916; 95% confidence interval, 0.864 to 0.970). A subgroup analysis showed that hyperuricemia was associated with a lower risk of osteoporosis in females, but not in males. Women with serum uric acid greater than 8.0 mg/dL were not associated with a greater risk of osteoporosis. Our study suggests that hyperuricemia decreases the risk of osteoporosis in females, but not in males. The protective role was no longer apparent when the serum uric acid level was greater than 8 mg/dL.

Comparison of Highly Intensive Home-Based Post-acute Care to Inpatient Program for Patients With Fragility Fractures After Surgery

Introduction

Evidence suggests that patients with fragility fractures would benefit from post-acute care (PAC); however, they have been subjected to varying PAC programs. This study aimed to compare the effectiveness of home-based PAC (HPAC) to inpatient PAC (IPAC) programs for patients with fragility fractures in Taiwan.

Materials and methods

This is a retrospective study that reviewed the medical records of patients who received HPAC or IPAC within three weeks after hip, knee, or spine fragility fractures in the Taipei City Hospital from September 1, 2017, to August 31, 2018.

Results

The mean age (78.9 ± 10.8 years) showed significant difference between the HPAC (age = 80.6 ± 11.1, n = 83) and the IPAC (age = 78.2 ± 10.6, n = 185) groups (P = .049). After PAC, both HPAC and IPAC groups showed improvement on Barthel index, numerical pain rating scale, and Harris hip score (all P < .001). Patients in the HPAC group displayed greater improvement than the IPAC group on Barthel Index for activities of daily living (ADLs) by 5.8 (95% confidence interval, 3.0 to 8.5). The IPAC group had a significant longer length of PAC than the HPAC group (12.4 ± 3.0 vs. 11.1 ± 2.7, P < .001).

Conclusion

Both PAC programs could significantly improve functional performance and reduce pain in patients with fragility fractures. Patients treated in the HPAC group had better ADLs, and less length of PAC.

Improved outcomes and reduced medical costs through multidisciplinary co-management protocol for geriatric proximal femur fractures: a one-year retrospective study

BACKGROUND

To manage the rapidly growing incidence of, and related medical burden resulting from hip fractures in older adults in an aging society, studies involving orthogeriatric co-management treatment models have reported improved outcomes, including reduced medical costs. The treatment gap for osteoporosis was however seldom emphasized in the published treatment protocols. Aiming to improve the existing orthogeriatric protocol, we have established a patient-centered protocol for elderly patient hip fractures, which simultaneously focuses on fracture care and anti-osteoporosis agent prescription in regarding to healthcare quality and medical expense.

METHODS

This was a retrospective study comparing patients who enrolled in the multidisciplinary co-managed protocol for geriatric hip fractures and those who did not. The inclusion criteria for this study were: (a) single-sided hip fractures treated from 1 to 2018 to 30 June 2020, (b) patients who were 60-years or older (c) trauma treated within 3 days from time of injury, and (d) minimal follow-up period of 12 months after surgery.

RESULTS

From 1 to 2018 to 30 June 2020, 578 patients were included (267 patients in the protocol group vs. 331 patients in the conventional group). The protocol group was associated with significantly reduced lengths of hospital stay (p = 0.041), medical expenditures (p = 0.006), and mortality (p = 0.029) during their acute in-hospital admission period. Early osteoporosis diagnosis and anti-osteoporosis agent prescription were achieved in the protocol group, with a significantly wider coverage for BMD assessment (p < 0.001) and prescriptions for anti-osteoporosis medication (p < 0.001). Yet, there was no significant decline in the one-year refracture rate in the protocol group.

CONCLUSIONS

The implementation of a multidisciplinary co-managed care protocol for geriatric proximal femur fractures successfully improved patient outcomes with significantly reduced lengths of stay, medical expenditures, and mortality during the acute in-hospital admission period. The high prescription rate of anti-osteoporosis medication after hip fractures in the protocol group was not associated with a significantly lower re-fracture rate in the 12-month follow-up. However, the association between early anti-osteoporosis agent prescription and reduced long-term medical expenses in this group of patients has provided a direction for future research.

Impact of subtrochanteric fractures in the geriatric population: better pre-fracture condition but poorer outcome than pertrochanteric fractures: evidence from the Spanish Hip Fracture Registry

Background

Clinical management in orthogeriatric units and outcome indicators are similar for extracapsular fragility hip fractures, without discriminating between subtrochanteric and pertrochanteric fractures.

Hypothesis

Geriatric patients, 75 years or older, with subtrochanteric fractures have worse clinical and functional outcomes than those with pertrochanteric fractures.

Materials and methods

Retrospective observational study of data prospectively collected by the Spanish Hip Fracture Registry including patients 75 years or older, admitted for extracapsular hip fractures from January 2017 to June 2019. Demographic and baseline status, pre-operative, post-operative and 30-day follow-up data were included.

Results

A total of 13,939 patients with extracapsular hip fractures were registered: 12,199 (87.5%) pertrochanteric and 1740 (12.5%) subtrochanteric. At admission, patients with subtrochanteric fractures were younger (86.5 ± 5.8 versus 87.1 ± 5.6 years old), had better pre-fracture mobility (3.7 ± 2.7 versus 3.9 ± 2.8) (1-to-10 scale, 1 being independent) and were more likely to be living at home; those with pertrochanteric fractures had worse cognitive function (Pfeiffer 3.3 ± 3.3 versus 3.8 ± 3.5). The subtrochanteric fracture group showed worse post-fracture mobility (7.3 ± 2.7 versus 6.7 ± 2.7) and greater deterioration of mobility (3.7 ± 3.0 versus 2.9 ± 2.7). Among individuals living at home at baseline, those with subtrochanteric fractures were more likely to remain in an assisted facility at 30-day follow-up. In-hospital mortality during acute admission was higher for the subtrochanteric group (5.6% versus 4.5%) (p = 0.028). To our knowledge, this is the first paper highlighting the differences between these two fracture groups in the geriatric population.

Conclusions

Subtrochanteric fractures in the older population are a different and worse entity, with greater morbimortality and functional decline than pertrochanteric fractures. Despite being younger and fitter at admission, older patients with subtrochanteric fractures have a higher risk of remaining non-weight bearing and undergoing re-operation and institutionalization. Orthogeriatric units should be aware of this and manage subtrochanteric fractures accordingly.

Level of evidence: IV.

Prognostic factors for 1-year functional outcome, quality of life, care demands, and mortality after surgery in Taiwanese geriatric patients with a hip fracture: a prospective cohort study

Background:

Hip fractures are a major public health concern among elderly individuals. This study aimed to investigate potential perioperative factors that predict 1-year functional outcome, quality of life (QoL), care demands, and mortality in geriatric patients with a hip fracture.

Methods:

We prospectively enrolled geriatric patients who had undergone hip fracture surgery in one medical center from December 2017 to December 2019. Basic demographic data, handgrip strength, and responses to questionnaires for QoL and activities of daily living (ADL) before the injury were collected at baseline. QoL, ADL, additional care demands other than family support, and mortality events were monitored at 1 year after the operation.

Results:

Among 281 patients with a hip fracture, 39 (13.9%) died within 1 year of the index operation. The mean follow-up interval for the survivors was 403.3 (range: 358–480) days. Among the 242 survivors, ADL and QoL considerably decreased at approximately 1 year following hip surgery. Up to 33.9% of the participants became severely dependent and needed additional care at 1-year follow up. Prefracture ADL status was the crucial predictor for functional outcome, QoL, and additional care demand at 1-year follow up. Cox regression models indicated that male sex, low preoperative serum creatinine, handgrip strength, long surgical delay after a falling accident, and high Charlson Comorbidity Index were considerably associated with a high 1-year mortality risk in the geriatric hip fracture population.

Conclusion:

Hip fracture has long-lasting effects (e.g. functional loss, decline in QoL, increased care demands, and high postoperative mortality rate) on the geriatric population. A robust screening method must be developed for identifying potential prognostic factors, and a stratified care approach must be used that accounts for personalized risks to improve functional outcomes and reduce mortality after hip fracture in geriatric patients, especially in Taiwan.

Hospital length of stay after hip fracture and its association with 4-month mortality - Exploring the role of patient characteristics

Background

Hospital length of stay (LoS) is believed to be associated with higher mortality in hip fracture patients; however, previous research has shown conflicting results. We aimed to explore the association between LoS and 4-month mortality in different groups of hip fracture patients.

Methods

The study population in this Swedish register-based cohort study was 47 811 patients 65 years or older with a first hip fracture during 2012–2016, followed up for 4 months after discharge. LoS was categorized by cubic splines, and the association between LoS and mortality was analyzed with Cox regression models, adjusted for sociodemographic- and health-related factors.

Results

Mean LoS was 11.2 ± 5.9 days and 12.3% of the patients died within 4 months. Both a shorter and a longer LoS, compared to the reference 9–12 days, were associated with higher mortality (hazard ratio [95% confidence interval]): 2–4 days 2.15 (1.98–2.34), 5–8 days 1.58 (1.47–1.69), and 24+ days 1.29 (1.13–1.46). However, in fully adjusted models, only the association with a long LoS remained: 13–23 days 1.08 (1.00–1.17) and 24+ days 1.42 (1.25–1.61). Stratifying by living arrangement revealed that the increased risk for a short LoS was driven by the group living in care homes. For patients living at home, a short LoS was associated with lower risk: 0.65 (0.47–0.91) and 0.85 (0.74–0.98) for 2–4 and 5–8 days, respectively.

Conclusions

A long LoS after a hip fracture is associated with increased 4-month mortality risk even after considering patient characteristics. The association between mortality and a short LoS, however, is explained by individuals coming from care homes (with higher mortality risk), being discharged early.

The incidence of arm, forearm, and hip osteoporotic fractures during early stage of COVID-19 pandemic

The study analyzes whether the COVID-19 pandemic affects the incidence of arm, forearm, and hip fractures. Additionally, the change in the overall cost of those fractures treatment was estimated. During the COVID-19 pandemic, the incidence of arm, forearm, and hip fractures and the cost of fracture management are decreased.

INTRODUCTION

Purposes of the study were to analyze if COVID-19 pandemic influences the incidence of arm, forearm, and hip osteoporotic fractures and to estimate the changes in costs of their management.

METHODS

Data on arm, forearm, and hip fracture incidence were collected for inhabitants aged over 50 years in the district of Tarnowskie Góry and the city of Piekary Śląskie, South Poland, in the early stage of COVID-19 pandemic (77 days, from March 16th to May 31st 2020). These results were compared with the number of fractures noted in years 2015-2019 in the same period of the year. The ratio of analyzed fractures per 100,000 inhabitants was calculated.

RESULTS

The recorded numbers of fractures of arm, forearm, and hip were 13, 43, and 29, respectively. The respective mean number for fractures reported in corresponding period in 2015-2019 years was 23.6, 52, and 33. The year fracture incidence calculated per 100,000 inhabitants decreased by 45.8%, 18.4%, and 13.4%, respectively. The estimated numbers of avoided fractures extrapolated for the whole country for arm, forearm, and hip were 1722, 1548, and 947, respectively. The total number of avoided fractures was 4217. The expected nationwide cost reduction for the arm, forearm, and hip fracture management was estimated at € 568,260, € 332,820, and € 1,628,840, respectively. The total cost reduction was € 2,529,920 over the period of observation.

CONCLUSION

During COVID-19 pandemic, a decrease of arm, forearm, and hip fracture incidence was observed which may result in decrease of total costs for Polish healthcare system.

Real-world cost-effectiveness analysis of the fracture liaison services model of care for hip fracture in Taiwan

BACKGROUND

This study was to perform an economic evaluation to understand clinical outcomes and health resource use between hip fracture patients receiving hospital-based postfracture fracture liaison service (FLS) care and those receiving usual care (UC) in Taiwan.

METHODS

This cohort study included hospital-based data of 174 hip fracture patients who received FLS care (FLS group) from National Taiwan University Hospital, and 1697 propensity score-matched patients who received UC (UC group) of National Health Insurance claim-based data. Two groups had similar baseline characteristics but differed in hip fracture care after propensity score matching. Clinical outcomes included refracture-free survival (RFS), hip-refracture-free survival (HRFS), and overall survival (OS). Health resource use included inpatient, outpatient, and pharmacy costs within 2 years follow-up after the index of hip fracture. The economic evaluation of the FLS model was analyzed using the net monetary benefit regression framework based on the National Health Insurance perspective.

RESULTS

The FLS group had longer RFS than the UC group, with an adjusted difference of 44.3 days (95% confidence interval: 7.2-81.4 days). Two groups did not differ in inpatient and outpatient costs during follow-up, but the FLS group had a higher expenditure than the UC group on osteoporosis-related medication. The probability of FLS being cost-effective was >80% and of increasing RFS, HRFS, and OS was 95%, 81%, and 80%, respectively, when the willingness-to-pay threshold was >USD 65/gross domestic product per day.

CONCLUSION

FLS care was cost-effective in reducing refracture occurrence days for patients initially diagnosed with hip fractures.

Current and Future Burden of Hip and Vertebral Fractures in Asia

The increase in the incidence of hip fractures over time disappeared in Northern European and North American Caucasians after 2000, while an increase was observed in Asian countries including Japan until 2010. However, a decrease in the incidence was observed after 2010. The prevalence of vertebral fractures in Asians, Europeans, and American Caucasians is similar, and the incidences of clinical and morphometric vertebral fractures are higher in Asians compared with European Caucasians. The decrease in the incidence of vertebral fractures over time has been observed in Japan. Although the stabilization or decrease over time in the incidence of hip and vertebral fractures have been observed, the number of patients with these fractures is expected to increase rapidly with increases in the elderly population. Multidisciplinary measures to prevent fragility fractures are an urgent issue in Asia at this time. This narrative review outlines the recent trends in incidence and future burdens of hip fracture and vertebral fracture in Asia.

Trends in Hip Fracture Incidence in Japan: Estimates Based on Nationwide Hip Fracture Surveys From 1992 to 2017

As of 2015, the aging population in Japan was the largest in the world. Although the National Database of Health Insurance Claims (NDB) was developed in 2012, long‐term trends regarding hip fracture incidence in Japan remain unclear. In order to clarify the trend in hip fracture incidence from 1992 to 2017, we estimated the number of new hip fractures in 2017, the seventh in a series of nationwide hip fracture surveys performed every 5 years since 1987. We also investigated regional differences in hip fracture incidence. We collected data through a nationwide mail‐in survey of orthopedic institutions in Japan and calculated hip fracture incidence by sex and age, as well as standardized incidence ratio (SIR) across 12 districts. The total number (95% confidence interval) of hip fractures in 2017 was estimated at 193,400 (187,300–199,500), occurring in 44,100 (42,700–45,500) males and 149,300 (144,500–154,100) females. Of all the hip fracture surveys from 1992 to 2017, the 5‐year hip fracture increase rates from 2012 to 2017 was the lowest among female patients. In males, the 5‐year rates from 2012 to 2017 were lower than those from 2007 to 2012. The age‐adjusted incidence rates for patients in both sexes did not show significant change in the 25‐year period. The estimated incidence rates in 2017 for patients aged 70 to 79 years in both sexes were lowest from 1992 to 2017, and declined significantly over the 25‐year period. SIRs differed between northeast and southwest regions. Our findings were similar to those from a previous study in Japan using the NDB from 2012 to 2015. Progress in the development of osteoporosis medication may contribute to the continuous decline in the 70‐year to 79‐year age group. © 2020 American Society for Bone and Mineral Research © 2020 The Authors.

Low rates of all-cause revision in displaced subcapital femoral neck fractures treated with hip hemiarthroplasty - a retrospective review of 4516 patients from a single institute

Background

Femoral neck fracture (FNF) is among the commonest fractures affecting the geriatric population. Hemiarthroplasty (HA) is a standard treatment procedure and has been performed by hip surgeons for decades. Recently, primary total hip replacement has proved advantageous for the treatment of such fractures.

The aim of this study is to retrospectively review all causes of failure of all patients who underwent HA in our institute and reevaluated whether HA remains a favourable choice of treatment for patients with displaced FNFs.

Methods

A total of 4516 patients underwent HA at our centre from 1998 to 2017. The HA implants included unipolar and bipolar prostheses. Patients diagnosed with displaced FNF, underwent primary HA initially, required second revision procedures, and followed up for a minimum of 36 months were included in this study. Data were collected and comprehensively analysed.

Results

In 4516 cases, 99 patients underwent second surgeries. The revision rate was 2.19%. Reasons for failure were acetabular wear (n = 30, 30.3%), femoral stem subsidence (n = 24, 24.2%), periprosthetic fracture (n = 22, 22.2%), infection (n = 16, 16.2%), and recurrent dislocation (n = 7, 7.1%). The mean follow-up period was 78.1 months. The interval between failed HA and revision surgery was 22.8 months.

Conclusion

HA has a low revision rate and remains a favourable choice of treatment for patients with displaced FNFs.

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

OBJECTIVE

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

SETTING AND PARTICIPANTS

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

OUTCOME MEASURES

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

RESULTS

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

CONCLUSIONS

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

Does preoperative dipyridamole-thallium scanning reduce 90-day cardiac complications and 1-year mortality in patients with femoral neck fractures undergoing hemiarthroplasty?

Background

This study aimed to evaluate the effect of dipyridamole-thallium scanning (DTS) on the rates of 90-day cardiac complications and 1-year mortality in patients with a femoral neck fracture treated with hemiarthroplasty.

Methods

Between 2008 and 2015, 844 consecutive patients who underwent cemented or cementless hemiarthroplasty were identified from the database of a single level-one medical center. One-hundred and thirteen patients (13%) underwent DTS prior to surgery, and 731 patients (87%) did not. Patient characteristics, comorbidities, surgical variables, and length of the delay until surgery were recorded. A propensity score-matched cohort was utilized to reduce recruitment bias in a 1:3 ratio of DTS group to control group, and multivariate logistic regression was performed to control confounding variables.

Results

The incidence of 90-day cardiac complications was 19.5% in the DTS group and 15.6% in the control group (p = 0.343) among 452 patients after propensity score-matching. The 1-year mortality rate (10.6% vs 13.3%, p = 0.462) was similar in the two groups. In the propensity score-matched patients, utilization of DTS was not associated with a reduction in the rate of 90-day cardiac complications (matched cohort, adjusted odds ratio [aOR] = 1.32; 95% confidence interval [CI] 0.75–2.33, p = 0.332) or the 1-year mortality rate (aOR = 0.62; 95% CI 0.27–1.42, p = 0.259). Risk factors for cardiac complications included an American Society of Anesthesiologists grade ≥ 3 (OR 3.19, 95% CI 1.44–7.08, p = 0.004) and pre-existing cardiac comorbidities (OR 5.56, 95% CI 3.35–9.25, p < 0.001). Risk factors for 1-year mortality were a long time to surgery (aOR 1.15, 95% CI 1.06–1.25, p = 0.001), a greater age (aOR 1.05, 95% CI 1.00 to 1.10, p = 0.040), a low body mass index (BMI; aOR 0.89, 95% CI 0.81–0.98, p = 0.015), and the presence of renal disease (aOR 4.43, 95% CI 1.71–11.46, p = 0.002).

Discussion

Preoperative DTS was not associated with reductions in the rates of 90-day cardiac complications or 1-year mortality in patients with a femoral neck fracture undergoing hemiarthroplasty. The necessity for DTS should be re-evaluated in elderly patients with femoral neck fractures, given that this increases the length of the delay until surgery.

Secular Trends in the Incidence of Hip Fracture Among Nursing Home Residents

A recent study suggested a decline in the incidence of hip fracture among US women between 2002 and 2012, followed by a leveling in the incidence rate from 2013 to 2015. Newly admitted nursing home residents are particularly vulnerable to hip fracture, and it is unclear whether that trend is observed in this high risk group. The purpose of our study was to describe trends in hip fracture rates and postfracture mortality among 2.6 million newly admitted US nursing home residents from 2007 to 2015, and to examine whether these trends could be explained by differences in resident characteristics. Medicare claims data were linked with the Minimum Data Set (MDS), a clinical assessment performed quarterly on all nursing home residents. In each year (2007-2015), we identified newly admitted long-stay (ie, 100 days in the same facility) nursing home residents. Hip fracture was defined using Medicare Part A diagnostic codes. Follow-up time was calculated from the index date until the first event of hospitalized hip fracture, Medicare disenrollment, death, or until 1 year. Poisson regression was used to adjust rates of hip fracture for age and sex. The number of newly admitted nursing home residents ranged from 324,508 in 2007 to 257,350 in 2015. Although mean age remained similar (83 years), residents were more functionally dependent over time. There was a small absolute decrease in the incidence rate of hip fracture between 2007 (3.32/100 person-years) and 2013 (2.82/100 person-years), with an increase again in 2015 (3.03/100 person-years). Adjusting for patient characteristics somewhat attenuated these trends. One-year mortality was high following fracture in all years (42.6% in 2007, 42.1% in 2014). In summary, we observed a recent slight rise in the incidence rates of hip fracture among nursing home residents that was at least partially explained by differences in resident characteristics over time. © 2020 American Society for Bone and Mineral Research.

The high prevalence of sarcopenia and its associated outcomes following hip surgery in Taiwanese geriatric patients with a hip fracture

BACKGROUND

Sarcopenia, which is a common risk factor for falls and fractures, affects the functional outcome and mortality in geriatric populations. However, the prevalence of sarcopenia among geriatric Taiwanese patients with a hip fracture is unknown, nor is the effect of sarcopenia on the outcome of hip surgery.

METHODS

From December 2017 to February 2019, geriatric patients who underwent surgery for a hip fracture were prospectively enrolled. Basic demographic data, responses to questionnaires for dementia screening and quality of life (QoL) and daily living activities (ADL) before the injury were analyzed to identify any association with sarcopenia. The QoL and ADL were monitored at six months after the operation to determine the difference between hip fracture patients with or without sarcopenia.

RESULTS

Of 139 hip fracture patients, 70 (50.36%) were diagnosed with sarcopenia. Accounting for all confounding factors in the multivariate logistic regression, lower body mass index (BMI), male gender and a weaker handgrip are the risk factors that are most strongly associated with a diagnosis of sarcopenia in geriatric patients with a hip fracture. Hip fracture patients with sarcopenia also have poor ADL and a lower QoL than patients without sarcopenia before the injury and six months after the operation.

CONCLUSION

A high prevalence of sarcopenia among geriatric hip fracture patients is associated with a poor mid-term outcome following hip surgery. Clinicians must recognize the risk of sarcopenia, especially for male hip fracture patients with a lower BMI and a weaker handgrip.

Secular Trends of Hip Fractures in Lebanon, 2006 to 2017: Implications for Clinical Practice and Public Health Policy in the Middle East Region

Country-specific hip fracture incidence rates (IRs) and longevity allow the Fracture Risk Assessment Tool (FRAX) to be adapted to individual countries. Secular trends can affect tool calibration. Data on hip fracture IRs in the Middle East is scarce, and long-term secular trend studies are nonexistent. Using the Ministry of Public Health hip fracture registry, we calculated age- and sex-specific hip fracture IRs in Lebanon, from 2006 to 2017, among individuals aged ≥50 years. We used Kendall's tau-b (τb) test to determine the correlation between time and hip fracture IRs, and calculated both the annual % change in IRs and the % change in IR compared to the baseline period (2006 to 2008). The registry recorded 6985 hip fractures, 74% at the femoral neck, 23% intertrochanteric, and 3% subtrochanteric. Men constituted 32% of the population, and were significantly younger than women (76.5 ± 11.0 years versus 77.7 ± 10.3 years; p < 0.001). Annual overall IRs, per 100,000, ranged from 126.6 in 2014 to 213.2 in 2017 in women, and 61.4 in 2015 to 111.7 in 2017 in men. The average women to men IR ratio was 1.8 (range, 1.5 to 2.1). IRs steadily increased with age, and IR ratios increased in parallel in both sexes, with a steeper and earlier rise (by 5 years) in women. Data showed a consistent decline in hip fracture IRs starting in 2006 in women, and in 2009 in men. There was a significant negative correlation between time (2006 to 2014) and hip fracture IRs in women (τb = -0.611, p = 0.022) but not in men (τb = -0.444, p = 0.095). The steady decrease in IRs reversed after 2015 in both sexes. This long-term data on secular trends in the Middle East is novel and consistent with worldwide changes in hip fracture rates. The impact of such changes on national FRAX-derived estimates is unclear, should be assessed, and may necessitate an update in the FRAX Lebanon calculator. © 2019 American Society for Bone and Mineral Research.

Frailty is Associated with an Increased Risk of Major Adverse Outcomes in Elderly Patients Following Surgical Treatment of Hip Fracture

We intended to explore the effect of level of frailty on, and relationship with, 1-, 3-, and 6-month postoperative emergency department visits, readmissions, and mortality. This is a prospective multicenter observational cohort study design. Patients aged 50 years or older treated for hip fracture (n = 245) were taken from Orthopedic wards in one medical center (n = 131) and one district hospital (n = 114) in Changhua County, Taiwan. Frailty was defined as measured by the validated Clinical Frailty Scale and categorized as robust, pre-frail, and frail. We used Kaplan-Meier analysis to estimate survival rates and Cox regression to estimate the risk of frailty associated with adverse outcomes. To examine the longitudinal associations between frailty and adverse outcome, the cross-lagged models were explored. Of the 245 patients, 55 (22.4%) were classified as frail, 113 (46.1%) as pre-frail, and 77 (31.4%) as robust. More cumulative events occurred for frail than for robust patients for each adverse outcome. Frailty has long-term effect on each adverse outcome after discharge, rather than the effect simultaneously. Targeting pre-frailty and frailty is essential for prevent adverse outcomes and improving the overall health of older adults after discharge for hip fracture.

The incidence of hip fracture and mortality rate after hip fracture in Korea: A nationwide population-based cohort study

Objectives

Osteoporotic hip fractures are associated with high mortality in the older population. Few population studies have reported the long-term trends of incidence and mortality rate of hip fracture among the older in Korea. This study assessed the incidence and mortality rate within 1 year after hip fracture from 2006 to 2015 in South Korea.

Methods

The National Health Information Database was used to identify adults aged 60 years and older with a diagnosis of hip fracture and died within 1 year from hip fracture. Regression analyses were performed to estimate the change of the incidence of hip fracture and the related mortality rate.

Results

The events causing hip fracture increased 1.85 times (1.91 times in women and 1.71 times in men), and the incidence of hip fracture increased 1.23 times (1.30 times in women and 1.11 times in men) from 2006 to 2015. The mortality rate after hip fracture decreased by 10% in women; however, it increased by 13% in men. These trends were more prominent in the older population.

Conclusions

Although the mortality rate after hip fracture in women decreased, other parameters associated with hip fracture have worsened during the last decade. Nationwide programs were urgently needed to reduce the future socioeconomic burdens of hip fractures.

Relationship between Helicobacter pylori infection and osteoporosis: a systematic review and meta-analysis

OBJECTIVES

Many studies have explored the association between Helicobacter pylori infection and osteoporosis. However, the results remain controversial. Therefore, we performed this systematic review and meta-analysis to evaluate the association between H. pylori infection and osteoporosis.

DESIGN

Systematic review and meta-analysis of case-control studies.

DATA SOURCES

Databases, including PubMed, Embase, Web of Science and Chinese Biomedical Literature Database, were screened from inception to 30 April 2018.

ELIGIBILITY CRITERIA

Case-control studies aimed at assessing the association between H. pylori infection and osteoporosis.

DATA EXTRACTION AND ANALYSIS

Study characteristics and study quality sections were reviewed. Studies were selected, and data were extracted by two reviewers. Pooled ORs and 95% CIs were calculated using random effects model if heterogeneity existed; otherwise, fixed effects model was used. Subgroup analyses were performed to explore the source of heterogeneity. Publication bias and sensitivity analyses were also tested.

RESULTS

A total of 21 studies with 9655 participants were included in our analyses. Taking together, we found that H. pylori infection was associated with increased odds of osteoporosis (OR (95% CI): 1.39 (1.13 to 1.71)); there was no significant difference between osteoporosis and osteopaenia; the association between osteoporosis and H. pylori infection was relatively higher in men than women but did not reach significant level. However, the decrease of bone mineral density in H. pylori-positive patients was not significant when compared with H. pylori negative controls, which may due to the sample size.

CONCLUSIONS

Our meta-analysis suggests an association between osteoporosis and H. pylori infection. The clinicians should pay more attention to the patients infected with H. pylori. Further studies were still needed to exploring the confounding factors among studies and to elucidate the underlying biological mechanisms.

Associations of body mass index and diabetes with hip fracture risk: a nationwide cohort study

Background

The high prevalence of diabetes is associated with body mass index (BMI), and diabetes can cause many complications, such as hip fractures. This study investigated the effects of BMI and diabetes on the risk of hip fractures and related factors.

Methods

We retrospectively reviewed data from 22,048 subjects aged ≧ 40 years from the National Health Interview Survey in Taiwan (NHIST) in 2001, 2005, and 2009. We linked the NHIST data for individual participants with the National Health Insurance Research Database (NHIRD), which includes the incidence of hip fracture from 2000 to 2013. We defined five categories for BMI: low BMI (BMI < 18.5), normal BMI (18.5 ≦ BMI < 24), overweight (24 ≦ BMI < 27), mild obesity (27 ≦ BMI < 30), and moderate obesity (BMI ≧ 30). The Cox proportional hazards model was used to analyze the effects of BMI and diabetes on risk of hip fracture.

Results

The Cox proportional hazards model shows that hip fracture risk in participants with diabetes was 1.64 times that of non-diabetes patients (95% confidence interval [CI]:1.30–2.15). Participants with low BMIs showed a higher hip fracture risk (HR: 1.75) than those with normal BMI. Among the five BMI groups, compared with non-diabetes patients, only diabetes patients with a normal BMI showed a significantly higher risk on hip fracture (HR: 2.13, 95% CI: 1.48–3.06). In participants with diabetes, compared with those with normal BMI, those with overweight or obesity showed significantly lower hip fracture risks (HR: 0.49 or 0.42). The hip fracture risk in participants who expend ≧ 500 kcal/week in exercise was 0.67 times lower than in those who did not exercise.

Conclusions

Diabetes and low BMI separately are important risk factors for hip fracture. There was an interaction between diabetes and BMI in the relationship with hip fracture (p = 0.001). The addition of energy expenditure through exercise could effectively decrease hip fracture risk, regardless of whether the participants have diabetes or not. The results of this study could be used as a reference for health promotion measures for people with diabetes.

Dementia predicted one-year mortality for patients with first hip fracture: a population-based study

Aims

We aimed to determine the effect of dementia and Parkinson's disease on one, three and 12-month mortality following surgery for fracture of the hip in elderly patients from an Asian population.

Patients and Methods

Using a random sample of patients taken from the Taiwan National Health Insurance Research Database, this retrospective cohort study analyzed the data on 6626 elderly patients who sustained a fracture of the hip between 1997 and 2012 who had ICD-9 codes within the general range of hip fracture (820.xx). We used Cox regression to estimate the risk of death associated with dementia, Parkinson's disease or both, adjusting for demographic, clinical, treatment, and provider factors.

Results

Among 6626 hip fracture patients, 10.20% had dementia alone, 5.60% had Parkinson's disease alone, and 2.67% had both. Corresponding one-year mortality rates were 15.53%, 11.59%, and 15.82%, compared with 9.22% for those without neurological illness. Adjusted hazard ratio for one-year mortality was 1.45 (95% confidence intervals (CI) 1.17 to 1.79) for those with dementia, and 1.57 (95% CI 1.07 to 2.30) with both dementia and Parkinson's disease versus patients with neither. There was no significant association with death for Parkinson's disease alone. Age, male gender and comorbidities were also associated with a higher risk of mortality.

Conclusion

Dementia, with or without Parkinson's disease, is an independent predictor of mortality following surgery for fractures of the hip. Age, male gender and comorbidities also increase the risk of death. Parkinson's disease alone has no significant effect. Cite this article: Bone Joint J 2018;100-B:1220-6.

Relationship between Helicobacter pylori infection and bone mineral density: a retrospective cross-sectional study

BACKGROUND

Helicobacter pylori (H. pylori) infection can induce individual inflammatory and immune reactions which associated with extra-digestive disorders. Our aim is to investigate the association between H. pylori infection and bone mineral density.

METHODS

This retrospective cross-sectional study was performed by using the data from the health examination database in a medical center of southern Taiwan in 2013. We investigated the relationship between sex, age, body mass index (BMI), waist circumstance, lipid profile, H. pylori infection, the findings of upper gastrointestinal endoscopy and bone mineral density (BMD). Because of nonrandomized assignment and strong confounding effect of age on BMD, the 1:1 propensity score match was applied for age adjustment. The simple and multiple stepwise logistic regression analysis were performed to assess the risk factors of decreased BMD in these well-balanced pairs of participants.

RESULTS

Of the 867 subjects in final analysis with the mean age of 55.9 ± 11.3 years, 381 (43.9%) subjects had H. pylori infection, and 556 (64.1%) subjects had decreased BMD. In decreased BMD group, the portion of woman was higher than a normal BMD group (37.2% versus 29.6%, P = 0.023), the age was significantly older (59.4 ± 9.8 versus 49.8 ± 11.3, p < 0.001) and BMI was significantly lower (24.7 ± 3.5 versus 25.4 ± 3.7, p = 0.006) than the normal BMD group. The prevalence of H. pylori infection was 39.9% and 46.2% in the normal BMD group and the decreased BMD group respectively (P = 0.071). The multivariate analysis which was used for these possible risk factors showed that only advanced age (OR 1.09, 95% CI 1.08-1.11, P < 0.001), and low BMI (OR 0.91, 95% CI 0.87-0.95, P < 0.001) were independently significantly associated with decreased BMD in this nonrandomized study. In the propensity score-matched participants, the multiple stepwise logistic regression analysis revealed H. pylori infection (OR 1.62, 95% CI 1.12-2.35, P = 0.011) and low BMI (OR 0.92, 95% CI 0.87-0.97, P = 0.001) were independently significantly associated with decreased BMD.

CONCLUSIONS

H. pylori infection and low BMI were independently significantly associated with decreased BMD in selected propensity score-matched populations after age adjustment.

Socioeconomic Inequality in One-Year Mortality of Elderly People with Hip Fracture in Taiwan

Hip fracture commonly results in considerable consequences in terms of disability, mortality, long-term institutional care and cost. Taiwan launched its universal health insurance coverage in 1995, which largely removes financial barriers to health care. This study aims to investigate whether socioeconomic inequality in one-year mortality exists among Taiwanese elderly people. This population-based cohort study included 193,158 elderly patients (≥65 years) admitted for hip fracture between 2000 and 2012. With over a one-year follow-up, 10.52% of the participants died from all causes. The mortality rate was low in the northern part of Taiwan and in urban and high-family-income areas. Multiple Poisson regression models further suggested that the level of >Q1-Q3 and >Q3-Max showed significantly reduced odds ratio of one-year mortality at 0.90 (95% confidence interval (CI), 0.87-0.93) and 0.77 (95% CI, 0.74-0.81), respectively, compared with that of the lowest family income level (i.e., Min.-Q1). Despite a monotonic decline in overall one-year mortality during the study period, socioeconomic inequality in one-year mortality rate remained evident. The annual percentage change in one-year mortality was higher (-2.86) in elderly people from families with high income (>Q3-Max.) than that for elderly patients from family with low income (Min.-Q1, -1.94). Accessibility, rather than affordability, to health care for hip fracture is probably responsible for the observed socioeconomic inequality.
