Chan LL, Ho YY, Taylor ME, Mcveigh C, Jung S, Armstrong E, Close JC, Harvey LA. Incidence of fragility hip fracture across the Asia-pacific region: A systematic review. Arch Gerontol Geriatr 2024; 123:105422. [PMID: 38579379 DOI: 10.1016/j.archger.2024.105422] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 03/11/2024] [Accepted: 03/20/2024] [Indexed: 04/07/2024]
Abstract
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.

Incidence of four major osteoporotic fragility fractures among older individuals in Sado, Japan, in 2020. J Bone Miner Metab 2024:10.1007/s00774-024-01529-z. [PMID: 38977436 DOI: 10.1007/s00774-024-01529-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Accepted: 06/17/2024] [Indexed: 07/10/2024]
Abstract
INTRODUCTION This study compared the 2020 incidence of fragility fractures in Sado City with those from 2004 to 2015. MATERIALS AND METHODS Data from patients aged ≥ 60 years living in Sado City with fragility fractures in the hip, vertebral, distal radius, and proximal humerus between January 1 and December 31, 2020, were collected. We examined the number and incidence of four types of osteoporotic fractures in the older population aged ≥ 60 years living in Sado City in 2020. We compared the results with those of the 2004, 2010, and 2015 surveys, examining the temporal change and trend in the incidence of the four fracture types in this population. We investigated the use rate of anti-osteoporotic medications and the relationship between their administration and the occurrence of fragility fractures. RESULTS The age-specific incidence of hip fractures slightly decreased from 2015. However, the incidence of the other three fractures slightly increased, although the difference was not statistically significant. The incidence of hip fractures markedly increased in the 80 s. In 2020, the percentage of patients taking anti-osteoporotic agents before the occurrence of fractures decreased to 12.4% from 14.5% in 2015; it increased from 4% in 2004 to 7.6% in 2010. CONCLUSION The 2020 incidence of the four fractures did not decrease, and the percentage of patients receiving anti-osteoporotic agents did not increase. A higher frequency of osteoporosis treatment is necessary to reduce the incidence of fragility fractures. We recommend using anti-osteoporotic agents to prevent hip fractures among individuals in their mid-70 s and above.

Hip Fractures in Elderly Individuals Did Not Decrease during the Coronavirus Disease 2019 Pandemic: Insights from the 2015 and 2020 Niigata Prefecture Fragility Hip Fracture Surveys. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:573. [PMID: 38674219 PMCID: PMC11052488 DOI: 10.3390/medicina60040573] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Revised: 03/27/2024] [Accepted: 03/28/2024] [Indexed: 04/28/2024]
Abstract
Background and Objectives: The incidence of osteoporotic hip fractures in Niigata Prefecture, Japan, has been studied approximately every 5 years since 1985. In 2020, as in previous surveys, a prefecture-wide survey was initiated as planned; however, the global outbreak of the coronavirus disease 2019 (COVID-19) began simultaneously. This study aimed to compare the results of the 2015 and 2020 Niigata Prefecture Fragility Hip Fracture Surveys to determine whether the COVID-19 pandemic affected the occurrence and treatment of proximal femoral fractures throughout Niigata Prefecture. Materials and Methods: In this study, data from the 2015 and 2020 Niigata Prefecture Fragility Hip Fracture Surveys were used. Data were obtained from registration forms returned by hospitals and clinics in Niigata Prefecture for patients living therein who were diagnosed with osteoporotic hip fractures over a 1-year period in 2015 and 2020. Results: In Niigata Prefecture, the total annual number of fractures increased from 3181 in 2015 to 3369 in 2020, whereas the age-adjusted fracture rate decreased. Regarding the location of the fractures, the proportion of outdoor fractures was lower than that of indoor fractures. The proportion of outdoor fractures decreased over the year as a whole, but in particular, the proportion of outdoor fractures decreased significantly under the issued emergency declarations. The most common reasons for delayed surgery related to COVID-19 were "waiting for PCR results" and "quarantine for fever," accounting for approximately 1.9% of all causes. Conclusions: In Niigata Prefecture, Japan, the effect of the COVID-19 pandemic on the number and rate of fractures was minuscule. The proportion of indoor fractures to outdoor fractures increased during the emergency declaration period. Considering that the number of fragility fractures remains the same during an infectious disease pandemic such as COVID-19, it is necessary to ensure that healthcare resources are available to deal with them.

Abstract
BACKGROUND Age-adjusted bone mineral density (BMD) in postmenopausal women decreases in developed countries whereas incidence of osteoporotic fracture decreases or remains stable. We investigated secular trends of bone density from 2008 to 2017 among different age groups of postmenopausal women. METHODS We analyzed BMD data obtained from health check-ups of 4,905 postmenopausal women during three survey cycles from 2008 to 2017. We divided them into 3 groups by age (50-59 years, 60-69 years, and 70 years or more) and observed the transition of lumbar and femoral BMD in each group, before and after adjusting for variables that may affect BMD. RESULTS Age-adjusted BMD, bone mineral content (BMC), and T-score demonstrated a declining trend over the survey period at lumbar spine (-2.8%), femur neck (-3.5%) and total femur (-4.3%), respectively. In the analysis for the age groups, the BMD, BMC, and T-score presented linear declining trend (-6.1%) in younger postmenopausal women while women aged over 70 or more showed linear increasing trends (+6.3%) at lumbar spine during the survey period. Femoral neck and total femur BMD demonstrated a declining linear trend only in the 50-59 and 60-69 years groups (-5.5%, -5.2%, respectively), but not in the 70 years or more group. CONCLUSION BMD in younger postmenopausal women has decreased considerably but has increased or plateaued in elderly women. This discordance of BMD trends among different age groups may contribute to decreased incidence of osteoporotic fracture despite a recent declining BMD trend in postmenopausal women.

[PMID: 37119329 PMCID: PMC10382328 DOI: 10.1007/s00198-023-06774-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Accepted: 04/21/2023] [Indexed: 05/01/2023]
Abstract
This study evaluated the incidence rates and societal burden of hip fractures in The Netherlands. Although incidence in the elderly population is decreasing and hospital stay is at an all-time low, the burden of medical costs and crude numbers of proximal femoral fractures are still rising in our aging population. PURPOSE The aim of this nationwide study was to provide an overview of the incidence rate and economic burden of acute femoral neck and trochanteric fractures in The Netherlands. METHODS Data of patients who sustained acute proximal femoral fractures in the period January 1, 2000, to December 31, 2019, were extracted from the National Medical Registration of the Dutch Hospital Database. The incidence rate, hospital length of stay (HLOS), health care and lost productivity costs, and years lived with disability (YLD) were calculated for age- and sex-specific groups. RESULTS A total of 357,073 patients were included. The overall incidence rate increased by 22% over the 20-year study period from 16.4 to 27.1/100,000 person-years (py). The age-specific incidence rate in elderly > 65 years decreased by 16% (from 649.1 to 547.6/100,000 py). The incidence rate in men aged > 90 has surpassed the incidence rate in women. HLOS decreased in all age groups, hip fracture subtypes, and sexes from a mean of 18.5 to 7.2 days. The mean health care costs, over the 2015-2019 period, were lower for men (€17,723) than for women (€23,351) and increased with age to €26,639 in women aged > 80. Annual cumulative costs reached €425M, of which 73% was spent on women. CONCLUSION The total incidence of hip fractures in The Netherlands has increased by 22%. Although incidence in the elderly population is decreasing and HLOS is at an all-time low, the burden of medical costs and crude numbers of proximal femoral fractures are still rising in our aging population.

Abstract
INTRODUCTION A 2015 study showed a decreasing trend in the incidence of osteoporotic hip fractures in Niigata Prefecture, Japan, which had been increasing. This study aimed to investigate the incidence of osteoporotic hip fractures in 2020, determine the long-term change in the incidence of hip fractures from 1985 to 2020, and assess whether the decline in fracture incidence since 2010 has continued. MATERIALS AND METHODS We obtained data from the registration forms submitted by hospitals and clinics of patients who lived in Niigata Prefecture and were diagnosed with osteoporotic hip fracture through a survey conducted from January 1, 2020 to December 31, 2020. RESULTS In 2020, 3,369 hip fractures were recorded in Niigata Prefecture. Although the overall incidence of age-specific hip fractures decreased, it increased in patients aged ≥ 90 years, regardless of sex. The proportion of patients receiving anti-osteoporosis drugs prior to hip fracture increased from 7.6% in 2004 to 17.3% in 2020. Notably, surgical treatment should be performed as early as possible, and the preoperative waiting time was 2.9 days, which was mainly due to holidays. CONCLUSION The incidence of hip fractures in Niigata Prefecture has gradually increased over the past 35 years, with an increasing change observed in the very elderly recently in 2020. Although the treatment of osteoporotic hip fractures in Niigata Prefecture is adequate, improvements may include increasing the rate of adoption of osteoporosis treatment further and decreasing the number of days of preoperative waiting.

Changing trends in hip fracture epidemiology in the Republic of Ireland: a follow-up study. Arch Osteoporos 2022; 17:79.

Abstract
A national, population-based study of hip fracture epidemiology is reported following a previously published study for the same population to ascertain the accuracy of projected incidence rates. Results suggest a decline in age-specific incidence rates in females but not males, and an over-estimation of same in the previously reported projections. PURPOSE Accurate estimates of hip fracture numbers and incidence rates are necessary for health service resource planning. A study in 2009 estimated projected figures for 2016 and 2026, for the Republic of Ireland. The purpose of the current study was to scrutinize these projections, based upon actual population and fracture statistics for the year 2016. METHODS Population data was obtained from the Central Statistics Office, and hip fracture data was obtained from the National HIPE Database for the year 2016, using similar search criteria to the previously published study. Hip fracture numbers and incidence rates were calculated. The calculated figures were compared to projected figures from the previous report. RESULTS Population projection models used in the 2009 paper accurately reflected the 2016 Irish population. For younger age groups, projected number of fractures closely estimated actual numbers, however, for those over 70 years of age, hip fracture projections overestimated the actual fracture numbers observed. There was a significant difference in the age-specific hip fracture rates in the over 70 s sub-groups compared to the published results of the 2009 study. CONCLUSIONS Hip fracture numbers continue to increase, though the age-specific incidence rates in the Republic of Ireland are reducing in the older age groups. The previously published study over-estimated hip fracture projections for the year 2016 (and potentially 2026) due to a false assumption of a stable age-specific incidence rate in the Republic of Ireland, which is in fact reducing.

Abstract
INTRODUCTION A previous review study showed the trends of declining age- and sex-adjusted incidence of hip fractures in almost all the countries, except Austria and Japan, in the most recent of the periods studied. However, the expansion of devices for diagnosis and drugs for fracture prevention in Japan was roughly the same as in the other countries. This study aimed to conduct a comprehensive systematic review and meta-analyses of incidence rates (IRs) of osteoporotic fractures reported over 30-years in multiple communities in Japan and to evaluate secular trends. MATERIALS AND METHODS We searched MEDLINE for observational studies reporting IRs of osteoporotic fractures in the general population. Additional studies were identified by hand searches of reference lists of published studies. Two reviewers and 1 expert independently assessed study eligibility. Pooled analyses of IRs were conducted by a random-effect model. Data from 3 periods (1985-1999, 2000-2009, and from 2010) were compared. RESULTS Of 47 eligible studies, 21 with IRs or information enabling recalculation of IRs in the population aged 50 years and older were included. IRs of hip fractures per 100,000 person-years significantly increased over time in men: 1985-1999, 0.79 (95% CI 0.71-0.87); 2000-2009, 1.18 (95% CI 1.09-1.28); and 2010 onwards, 1.31 (95% CI 1.17-1.45). They also significantly increased in women: 2.23 (95% CI 1.89-2.58); 3.99 (95% CI 3.70-4.28); and 4.39 (95% CI 4.00-4.78), respectively. CONCLUSION IRs of hip fractures continuously increased in the past 30-years in men and women despite improved the diagnosis, treatment, and care. Such data from Japan, a leading aging society, provide important information for other countries.

Abstract
BACKGROUND Hip fracture is among the most common injuries in elderly people. We aimed to investigate the decennial trends in hip fractures in patients ≥65 years of age. METHODS A questionnaire was distributed to all hospitals with a Department of Orthopaedic Surgery in Yamagata Prefecture to collect data on hip fractures occurring in 1996, 2006 and 2016. RESULTS The response rate was 100%. The total numbers of hip fractures in 1996, 2006 and 2016 were 665, 1169 and 1,728, respectively (crude incidence: 258, 373 and 494 per 100,000 person-year, respectively). Injuries frequently occurred in the early morning and daytime morning in 1996. In contrast, they frequently occurred in activity times (e.g., morning and afternoon) in 2006 and 2016. Among the patients, 80-90% were injured by simple falls, and 70-80% were injured indoors. The incidence of trochanteric fractures was approximately 1.8-1.9 times greater than incidence of neck fractures in all years. Especially, trochanteric fractures in females of ≥90 years of age markedly increased. The rate of surgical treatment was the same in 1996 and 2006, but was lower in 2016. In 1996, the percentage of independent walkers at discharge and 1 year later was almost the same. In 2006 and 2016, the rate of independent walkers was low at discharge, but increased 1 year later. The rate of discharge to home decreased gradually. The combined percentage of patients discharged to home and to rehabilitation institutions in 2006 and the percentage of patients who entered the regional referral clinical pathway in 2016 were both approximately 70%, with no marked changes observed. CONCLUSIONS Hip fractures, especially trochanteric fractures in super-aged females, increased. Discharge to home decreased, and the use of the regional referral clinical pathway was widespread. Ambulation ability was reduced at discharge, but improved after 1 year.

Osteoporos Int 2022; 33:89-96. [PMID: 34235549 DOI: 10.1007/s00198-021-06050-x] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Accepted: 06/24/2021] [Indexed: 11/25/2022]
Abstract
We investigated the secular trends of the incidence and hospitalization cost of hip fracture in Tangshan, China. The incidence of hip fracture and the hospitalization cost were both increasing during the observation period. INTRODUCTION The present study aimed to determine sex-, age-, and fracture type-specific incidence and annual changes in hip fractures in Tangshan, China, between 2007 and 2018. METHODS We analyzed annual hip fracture incidence using urban hospital data during 2007-2018 and calculated incidence rate/100,000 person years in each age group and sex. We assessed annual changes in incidence among people aged >60 years using linear-by-linear association tests and evaluated hospitalization costs with the Kruskal-Wallis test. RESULTS During the study period, we observed an increasing proportion of hip fractures in people >60 years old from 14.2 to 22.79%. Crude hip fracture incidence increased markedly from 140.87 to 306.56/100,000 in women (p < 0.01) and from 124.83 to 167.19/100,000 in men (p < 0.01) in the age group >60 years. Type-specific analysis indicated significantly increased trends in incidence of cervical and trochanteric fractures among women and cervical fracture among men (p < 0.01). In people aged 36-60 years, the trend of hip fracture increased significantly in both sexes. The total and cervical-to-trochanteric ratio in men increased, with significant upward trends (p < 0.01). The proportion of cervical fracture was higher than that for trochanteric fracture in women, with stable levels from 2007 to 2018. Hospitalization costs for cervical and trochanteric fractures increased by 51.91% and 53.20%, respectively, during 2011-2018. CONCLUSION Tangshan will have an increasing burden on health care resources attributable to a considerable rise in hip fracture incidence and the older population. Further investigation of risk factors and subsequent implementation of effective measures to prevent hip fracture are needed.

Abstract
BACKGROUND Geriatric acetabular fractures are becoming more common due to demographic changes. Compared with proximal femoral fractures, surgical treatment is more complex and often does not allow full-weight-bearing. The aims of this study were to compare operatively treated acetabular and proximal femoral fractures with regard to (1) cumulative 1-year mortality, (2) perioperative complications, and (3) predictive factors associated with a higher 1-year mortality. METHODS This institutional review board-approved comparative study included 486 consecutive surgically treated elderly patients (136 acetabular and 350 proximal femoral fractures). After matching, 2 comparable groups of 129 acetabular and 129 proximal femoral fractures were analyzed. Cumulative 1-year mortality was evaluated through Kaplan-Meier survivorship analysis, and perioperative complications were documented and graded. After confirming that the proportionality assumption was met, Cox proportional hazard modeling was conducted to identify factors associated with increased 1-year mortality. RESULTS The acetabular fracture group had a significantly lower cumulative 1-year mortality before matching (18% compared with 33% for proximal femoral fractures, log-rank p = 0.001) and after matching (18% compared with 36%, log-rank p = 0.005). Nevertheless, it had a significantly higher overall perioperative complication rate (68% compared with 48%, p < 0.001). In our multivariable Cox regression analysis, older age, perioperative blood loss of >1 L, and wheelchair mobilization were associated with lower survival rates after acetabular fracture surgery. Older age and a higher 5-item modified frailty index were associated with a higher 1-year mortality rate after proximal femoral fractures, whereas postoperative full weight-bearing was protective. CONCLUSIONS Despite the complexity of operative treatment and a higher complication rate after acetabular fractures in the elderly, the 1-year mortality rate is lower than that after operative treatment of proximal femoral fractures, even after adjustment for comorbidities.

Abstract
UNLABELLED 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.

Abstract
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.

Abstract
UNLABELLED In Kyoto Prefecture, Japan, the number of hip fractures increased during 2013-2017 compared to 2008-2012. However, the estimated overall incidence rate increased only in femoral neck fractures in men aged ≥75 and women aged ≥85. PURPOSE The incidence rate of hip fractures in Japan has plateaued or decreased. We investigated the annual hip fracture occurrences in Kyoto Prefecture, Japan, from 2008 to 2017. METHODS Patients aged 65 years and above who sustained hip fractures between 2008 and 2017 and were treated at one of the participating 11 hospitals were included. The total number of beds in these institutions was 3701, accounting for 21.5% of the 17,242 acute-care beds in Kyoto Prefecture. The change in incidence rate was estimated utilizing the population according to the national census conducted in 2010 and 2015. RESULTS The total number of hip fractures was 10,060, with 47.5% femoral neck fractures and 52.5% trochanteric fractures. A decrease in number was seen only in trochanteric fractures in the group of 75- to 84-year-old women. The population-adjusted numbers of femoral neck fractures showed a significant increase in all age groups in men, whereas in women, there was an increase in femoral neck fractures in the ≥85 group and trochanteric fractures in the age group 65-74, and a decrease in trochanteric fractures in the age group 75-84. The estimated change in incidence rate showed an increase in femoral neck fractures in men aged ≥75 and women aged ≥85. CONCLUSION In Kyoto Prefecture, the number of hip fractures increased in the second half of the study period (2013-2017) compared to the first half (2008-2012). However, the incidence rate had not increased, except in femoral neck fractures in men aged ≥75 and women aged ≥85.

Abstract
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.

Abstract
UNLABELLED The incidence rate of hip fracture in Tottori Prefecture tended to increase until 2018 in men, but it did not increase after 2010 in women. By type of fracture, the incidence rate of femoral neck fractures also increased over time in men, but no other changes were observed from 2010. PURPOSE The aims of this study were to determine the sex-, age-, and fracture-type-specific incidence rates of hip fractures in Tottori Prefecture between 2007 and 2018 and to compare the results with our past results to identify changes over time. METHODS All hip fractures in people aged 35 years or older living in Tottori Prefecture were surveyed from 2007 to 2018 throughout the entire prefecture, and the age- and sex-specific incidence rates were calculated. The incidence rates from 1986 to 1988, 1992 to 1994, 1998 to 2000, and 2004 to 2006 previously reported were used for the analysis. RESULTS In men, the age-adjusted number of patients adjusted by demographic structure based on the mean incidence rate for each 3-year period from 1986 to 2018 showed an increase in incidence over time compared with the incidence for 1986-1988 (p < 0.001). In women, the incidence rose over time compared with the incidence for 1986-1988 until 2004-2006 (p < 0.001), and no further increase was observed from 2010. The age-specific incidence rates of neck fracture in men were higher in 2010-2012 and 2016-2018 compared with 2004-2006 (p < 0.001), but those in women showed no increase with time. Those of trochanteric fracture did not change over time in either men or women. CONCLUSION The hip fracture incidence rate in Tottori Prefecture, Japan, tended to increase until 2018 in men, but it did not increase after 2010 in women.

Abstract
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.

Abstract
The aim of this study was to survey the incidence of osteoporotic fragility fractures, which include vertebral, hip, distal radius, and proximal humerus fractures, in patients ≥ 50 years of age, from 2004 to 2015, in Sado City, Japan. We examined temporal changes in the incidence of these fractures from 2010 through 2015. The incidence of vertebral (p < 0.001) and radius fractures (p = 0.001) was lower in 2015 than in 2010, with only the incidence of hip fracture (p = 0.013) being lower in 2015 than in 2004. With regard to age-specific incidences, there was a sharp increase in vertebral and hip fractures among the segment of the population 70-89 years old, with no remarkable change in the incidence of radial and humeral fractures. Pre-existing vertebral fractures were identified in 69.6% of patients with a hip fracture, 35.6% of patients with a distal radius fracture, and 55% of patients with a humeral fracture. Among patients with pre-existing vertebral fractures, 42.5% had a single fracture, whereas 57.5% had 2 or more fractures. The proportion of patients on anti-osteoporotic agents before the occurrence of fractures increased to 14.5% in 2015, compared to 4% in 2004 and 7.6% in 2010. We speculate that the increase in the use of anti-osteoporotic agents is the main reason for the declining incidence of fractures. Therefore, considering the sharp increase in hip and vertebral fractures among individuals in their mid-1970s and older, judicious use of anti-osteoporotic agents among these individuals could be useful for lowering the occurrence of these fractures.

Cost-effectiveness analysis of drugs for osteoporosis treatment in elderly Japanese women at high risk of fragility fractures: comparison of denosumab and weekly alendronate. Arch Osteoporos 2018; 13:94. [PMID: 30159632 DOI: 10.1007/s11657-018-0509-6] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2018] [Accepted: 08/19/2018] [Indexed: 02/03/2023]
Abstract
UNLABELLED This study's purpose was to clarify the cost-effectiveness of osteoporosis treatment. Denosumab treatment was cost-effective compared with alendronate treatment for elderly Japanese women at high risk of fragility fractures. Denosumab treatment might be cost-effective for patients with lower bone mineral density. PURPOSE In Japan's super-aged society, the prevention and treatment of osteoporosis are a critical issue with implications for the medical economy. This study's purpose was to clarify the cost-effectiveness of osteoporosis treatment with denosumab versus weekly alendronate for elderly Japanese women at high risk of fragility fractures. METHODS A Markov model was used for simulation analysis. The modeled population was 75-year-old Japanese women with a bone mineral density (BMD) of 65% of the young adult mean (YAM) (T-score, - 2.87) and a history of previous vertebral body fracture. The simulation model was repeated until patient age reached 100 years or death. Analysis was performed from the societal perspective. Costs and epidemiological data were derived from previous studies. The incremental cost-effectiveness ratio (ICER) was calculated from the simulation. We compared the ICER with willingness-to-pay. Additional analyses were performed with different combinations of age and BMD. Sensitivity analysis verified the robustness of the analysis. RESULTS For the modeled population, the ICER of denosumab versus alendronate treatment was estimated at US$40,241/quality-adjusted life year (QALY). The ICER of denosumab for 80-year-old women whose BMD was 60% of YAM was estimated at US$22,469/QALY. CONCLUSIONS Assuming willingness-to-pay as US$50,000/QALY, denosumab treatment for 75-year-old Japanese women with a BMD of 65% of YAM and a history of previous vertebral body fracture was cost-effective compared with alendronate treatment. Among over 75 years of age, denosumab treatment might be more cost-effective than alendronate for patients with a BMD of 65% of YAM or lower.

An updated hip fracture projection in Asia: The Asian Federation of Osteoporosis Societies study. Osteoporos Sarcopenia 2018; 4:16-21. [PMID: 30775536 PMCID: PMC6362950 DOI: 10.1016/j.afos.2018.03.003] [Citation(s) in RCA: 203] [Impact Index Per Article: 33.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2018] [Revised: 03/06/2018] [Accepted: 03/16/2018] [Indexed: 01/23/2023] Open
Abstract
OBJECTIVES Hip fracture is a major public health problem. Earlier studies projected that the total number of hip fracture will increase dramatically by 2050, and most of the hip fracture will occur in Asia. To date, only a few studies provided the updated projection, and none of them focused on the hip fracture projection in Asia. Thus, it is essential to provide the most up to date prediction of hip fracture in Asia, and to evaluate the total direct medical cost of hip fracture in Asia. METHODS We provide the updated projection of hip fracture in 9 Asian Federation of Osteoporosis Societies members using the most updated incidence rate and projected population size. RESULTS We show that the number of hip fracture will increase from 1,124,060 in 2018 to 2,563,488 in 2050, a 2.28-fold increase. This increase is mainly due to the changes on the population demographics, especially in China and India, which have the largest population size. The direct cost of hip fracture will increase from 9.5 billion United State dollar (USD) in 2018 to 15 billion USD in 2050, resulting a 1.59-fold increase. A 2%-3% decrease in incidence rate of hip fracture annually is required to keep the total number of hip fracture constant over time. CONCLUSIONS The results show that hip fracture remains a key public health issue in Asia, despite the available of better diagnosis, treatment, and prevention of fracture over the recent years. Healthcare policy in Asia should be aimed to reduce the burden of hip fracture.
