Thirty years of hip fracture incidence in Austria: is the worst over?
Ontology highlight
ABSTRACT: Purpose
In the Austrian population ≥ 50 years, nationwide hip fracture incidences over a period of 20 years (1989-2008) have shown an initial steep increase, followed by a leveling-off during the last few years of observation. The purpose of the present study was to follow up on hip fracture incidences for another 10 years (2009-2018) and to analyze trends over the entire period of 30 years.Methods
ICD-10 code classes S72.0, S72.1, and S72.2 were applied. All data were retrieved from the Statistics Austria database and its hospital discharge register. Annual absolute numbers, crude and age-standardized incidences, and incidence rate ratios (IRR) were stratified by sex and 5-year age intervals, and calculated by using a correction factor for multiple registrations.Results
Total number of hip fracture cases increased from 13,984 (2009) to 14,640 (2015), and decreased thereafter to 14,457 (2018), despite a persistent increase in men. Age-standardized incidences peaked at 476/100,000 (2010), followed by a decrease to 408/100,000 (2018). The observed overall decrease was mainly driven by the female population. Incidence rate ratios (IRRs) yielded a statistically significant average annual decrease of age-standardized incidences in both women and men (∆IRR 0.984; 0.981-0.987).Conclusion
While absolute numbers of hip fracture in women showed a slight decrease during the last 10 years of observation, numbers in men continued to increase. Age-standardized incidences nevertheless decreased in both men and women, which may be interpreted as a trend in the right direction. However, due to the rapid aging of the population, it cannot be precluded that this trend will be compromised during the next few decades.

Project description:BackgroundHip fractures in the elderly are a major public health burden. Data concerning secular trends of hip fracture incidence show divergent results for age, sex and regions. In Austria, the hip fracture incidence in the elderly population and trends have not been analysed yet.MethodsHip fractures in the population of 50 years and above were identified from 1994 to 2006 using the national hospital discharge register. Crude incidences (IR) per 100,000 person years and standardised incidences related to the European population 2006 were analysed. Estimate of age-sex-adjusted changes was determined using Poisson regression (incidence rate ratios, IRRs).ResultsThe number of hospital admissions due to hip fracture increased from a total number of 11,694 in 1994 to 15,987 in 2006. Crude incidences rates (IR) per 100.000 for men increased from 244.3 (95% confidence interval (CI) 234.8 to 253.7) in 1994 to IR 330.8 (95% CI 320.8 to 340.9) in 2006 and for women from 637.3 (95% CI 624.2 to 650.4) in 1994 to IR 758.7 (95% CI 745.0 to 772.4) in 2006. After adjustment for age and sex the annual hip fracture incidence increase was only small but statistically significant (IRR per year 1.01, 95% CI 1.01 to 1.01, p < 0.01). Change of IRR over the 12 years study period was 13%. It was significantly higher for men (IRR over 12 years 1.21, 95% CI 1.16 to 1.27) than for women (IRR over 12 years 1.10, 95% CI 1.06 to 1.14) (interaction: p = 0.03).ConclusionIn contrast to findings in other countries there is no levelling-off or downward trend of hip fracture incidence from 1994 to 2006 in the Austrian elderly population. Further investigations should aim to evaluate the underlying causes in order to plan effective hip fracture reduction programmes.

Project description: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.PurposeThe 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.MethodsAll 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.ResultsIn 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.ConclusionThe hip fracture incidence rate in Tottori Prefecture, Japan, tended to increase until 2018 in men, but it did not increase after 2010 in women.

Project description:ImportanceAge-adjusted hip fracture incidence is decreasing in the US. The decrease has been attributed to osteoporosis treatment, but the cause is unknown.ObjectiveTo examine the decrease in hip fracture incidence over the past 40 years in the US.Design, setting, and participantsA population-based cohort study using participants in the Framingham Heart Study was conducted. A total of 4918 men and 5634 women were followed up prospectively for the first hip fracture between January 1, 1970, and December 31, 2010. Data were analyzed from May 1, 2019, to May 30, 2020.Main outcomes and measuresIncidence of hip fracture and contemporaneous prevalence of risk factors for hip fractures analyzed with age-period-cohort models.ResultsThe study contained more than 105 000 person-years in 10 552 individuals with a gradual shift toward the offspring participants in the 1980s and 1990s. Women represented more than 55% of the study sample over the years. Adjusted for age, the incidence of hip fracture decreased by 4.4% (95% CI, 6.8%-1.9%) per year from 1970 to 2010. Both period associations (P < .001) and birth cohort associations (P < .001) were statistically significant. For example, in persons aged 85 to 89 years, the incidence of hip fracture was 759 per 100 000 person-years in the offspring group compared with 2018 per 100 000 person-years in the original cohort. The decrease in hip fracture incidence was coincident with a decrease in smoking and heavy drinking. Smoking decreased from 38% in the 1970s to 15% in the late 2000s, while heavy drinking decreased from 7.0% to 4.5%. The prevalence of other risk factors for hip fracture, such as underweight (body mass index <18.5), obesity (body mass index >30), and early menopause (age <45 years) were stable over the study period. When persons who never smoked were evaluated, a change in the incidence of -3.2% (95% CI, -6.0% to -0.4%) per year was observed. The difference between the decrease of the entire population and nonsmokers of 1.5% per year was similar to the hazard ratio conferred by smoking (hazard ratio, 1.5; 95% CI, 1.14-1.96).Conclusions and relevanceIn this study, individuals born more recently appeared to have a low risk for hip fracture. Reductions in smoking and heavy drinking were the risk factor changes coincident with the observed decrease in hip fracture. Attributing the decrease in hip fracture incidence up to 2010 solely to better treatment is not supported by these data, emphasizing the need to treat patients with osteoporosis while continuing to encourage public health interventions for smoking cessation and heavy drinking.

Project description:BackgroundHip fractures are associated with significant morbidity and mortality in the nursing home. Our objective was to describe the incidence rate (IR) of hip fracture according to age, sex, and race in a nationwide sample of long-stay nursing home residents.MethodsUsing 2007-2010 Medicare claims data linked with the Minimum Data Set, we identified 892,837 long-stay residents (≥100 days in the same nursing facility) between May 1, 2007 and April 30, 2008. Hip fractures were defined using Part A diagnostic codes (ICD-9). Residents were followed from the date they became a long-stay resident until the first event of death, discharge, hip fracture, or 2 years of follow-up.ResultsMean age was 84 years (range 65-113 years), and 74.5% were women. 83.9% were white and 12.0% were black. The overall IR of hip fracture was 2.3/100 person years. The IR was similar in men and women across age groups. The IR of hip fracture was highest in Native Americans aged 85 years or older (3.7/100 person years), in whites (2.6/100 person years), and during the first 100 days of institutionalization (2.7/100 person years). IRs of hip fracture were lowest in blacks (1.3/100 person years).ConclusionsIn nursing home residents surviving 100 days or more in a facility, the incidence of hip fracture is high, particularly among older white, Native American, and newly admitted residents. This is the first nationwide study to provide sex- and age-specific estimates among U.S. nursing home residents, and it underscores the magnitude of the problem.

Project description:In contrast to other cancers, survival rates for pancreatic ductal adenocarcinoma (PDAC) patients have improved but minimally over the past thirty years. The aim of this study was to perform a meta-analysis of clinical trials published since 1986 to determine trends in median overall survival in primarily metastatic PDAC.All Phase 2-4 clinical trials published during or after 1986 investigating first-line systemic chemotherapy in metastatic PDAC were included in the meta-analysis. Publications obtained through PubMed and www.ClinicalTrials.gov were cross-referenced to identify additional trials. Trials enrolling fewer than 50% of study participants with metastatic disease were excluded.Of 19,488 patients enrolled in 151 clinical trials, 84% had metastatic disease and 16% had locally advanced pancreatic cancer. In clinical trials published from 1986 to 2016, the weighted median overall survival (wMOS) increased by 3.0 months. The median wMOS was higher in combination therapy (7.31 months, IQR 5.4 to 8.5) compared to non-gemcitabine, single-agent therapy (4.76 months, IQR 3.5 to 6.0), gemcitabine monotherapy (6.48 months, IQR 5.9 to 7.2), and gemcitabine plus single-agent therapy (7.09 months, IQR 6.3 to 8.2). Of all regimens used in more than one study arm, FOLFIRINOX had the highest wMOS (10.9 months).Regardless of treatment regimen, survival rates in PDAC have minimally improved over time. Of drugs used in two or more study arms, only FOLFIRINOX has a wMOS greater than ten months. Emphasis should, therefore, be placed on identification of novel targets that promote early diagnosis and intervention.The authors on this manuscript are in parts, supported by grants from the National Institutes of Health (EDRN U01 CA200466, SPORE P50 CA127297, R01 CA183459, R21 AA026428 and R01 CA 195586).

Project description:Hip fracture patients often display an acute confusional state (delirium) which is associated with worse outcomes. In this observational study, we found that co-management of hip fracture patients by a multidisciplinary team including a geriatrician and an orthopaedic surgeon could reduce the incidence of delirium.IntroductionDelirium after hip fracture is common and is associated with negative outcomes. We investigated if orthogeriatric co-management reduced the incidence of delirium in hip fracture patients.MethodsIn this single-centre, prospective observational study, we compared the incidence of delirium and subsyndromal delirium (SSD) before (usual care group, n = 94) and after (orthogeriatric group, n = 103) the introduction of orthogeriatric co-management as an integrated care model. The outcome measure 'no delirium/SSD/delirium' was treated as an ordinal variable and analysed using the chi-squared test and multivariable ordinal logistic regression.ResultsThe groups had similar baseline characteristics except for a higher proportion of patients with pre-existing cognitive impairment in the usual care group (51% vs. 37%, p = 0.045). Fewer patients in the orthogeriatric group developed SSD or delirium (no delirium: 59% vs. 40%/SSD: 6% vs. 13%/delirium: 35% vs. 47%; p = 0.021). The number needed to treat (NNT) to avoid one case of SSD or delirium was 5.3 (95% CI: 3.1 to 19.7). In a multivariable analysis adjusted for age, sex, ASA class, pre-existing cognitive impairment, time to surgery, type of surgery, and medical or surgical complications, the odds ratio for the development of SSD/delirium was lower in the orthogeriatric group (OR = 0.46, 95% CI: 0.23-0.89, p = 0.023).ConclusionOrthogeriatric co-management as an integrated care model reduced the incidence of SSD/delirium in hip fracture patients.

Project description:BACKGROUND:It is known that mortality after hip fracture increases compared to the general population; the trend in mortality is a controversial issue. The objective of this study is to examine incidence, trends, and factors associated with mortality in patients with osteoporotic hip fractures. METHODS:This is a retrospective cohort study that uses the Registry for Hospital Discharges of the National Health System of our hospital. Patients older than 45 having an osteoporotic hip fracture between 1999 and 2015 were identified. Demographic data and comorbidities were obtained. A survival analysis was performed (Cox regression and Kaplan-Meier). Incidence rate, standardized death rate (SDR), trend (Poisson regression), and risk (hazard ratio) were calculated. RESULTS:During 1999-2015, in our hospital, there were a total of 3992 patients admitted due to osteoporotic hip fracture. Out of these 3992 patients, 3109 patients (77.9%) were women with an average age of 84.47 years (SD 8.45) and 803 (22.1%) were men with an average age of 81.64 years (SD 10.08). The cumulative incidence of mortality was 69.38%. The cumulative mortality rate for 12 months was 33%. The annual mortality was 144.9/1000 patients/year. The 1-year mortality rate increased significantly by 2% per year (IRR 1.020, CI95% 1.008-1.033). The median overall survival was 886 days (CI95% 836-951). The probability of mortality density for a period of 10 years following a hip fracture was 16% for women and 25% for men (first 90 days). The SDR was 8.3 (CI95% 7.98-8.59). Variables that showed statistically significant association with mortality were aged over 75, masculine, institutionalization, mild to severe liver disease, chronic kidney disease, COPD, dementia, heart failure, diabetes, the Charlson Index > 2 , presence of vision disorders and hearing impairment, incontinence, and Downton scale. CONCLUSIONS:For the last 17 years, an increase of mortality for patients with hip fracture and a higher mortality rate in men than in women were observed. Institutionalization combined with comorbidities is associated with a higher mortality.

Project description:UNLABELLED: The advantages of sonographic examination are well known, but its main disadvantage is that it might lead to overdiagnosis, which might cause overtreatment. Variations in the incidence of developmental dysplasia of the hip are well known. We ascertained the incidence of neonatal sonographic developmental dysplasia of the hip without considering the development of those joints during followup. All 45,497 neonates (90,994 hips) born in our institute between January 1992 and December 2001 were examined clinically and sonographically during the first 48 hours of life. Sonography was performed according to Graf's method, which considers mild hip sonographic abnormalities as Type IIa. We evaluated the different severity type incidence pattern and its influence on the total incidence during and between the investigated years. According to our study, sonographic Type IIa has major effects on the incidence of overall developmental dysplasia of the hip with a correlation coefficient of 0.95, whereas more severe sonographic abnormalities show relatively stable incidence patterns. LEVEL OF EVIDENCE: Level I, prognostic study. See the Guidelines for Authors for a complete description of levels of evidence.

Project description:BACKGROUND: More than 20% of the hip fracture patients die within the first year after the incident. Few data are available on the trends in mortality following a hip fracture. The present aim was to study changes in excess mortality after hip fracture from 1978/79 up to 1996/97. METHODS: Data on 5180 hip fracture patients aged ? 50 years, identified in three earlier, well validated, incidence studies from Oslo were used. The studies took place in the two years periods 1978-79 and 1989-89 and in a one year period from 1st of May 1996 to 30th of April 1997. The study was designed as a historic cohort study. Exposure was sustaining a hip fracture in the registration periods. Outcome was death of all causes. Age- and sex-specific one year-mortality rates were provided by Statistics Norway. Standardized mortality ratios (SMR) were calculated for the three cohorts for each sex and age-group, for the 0-6 months, 6-12 months, 0-1 year, 1-5 years and 5-10 years intervals after fracture. To assess the duration of the excess mortality in hip fracture patients, time-framed Kaplan-Meier curves for consecutive 5-years intervals were conducted for the hip fracture patients and the corresponding background population. Only patients still alive at the start of the time interval were included. One sample log rank tests were used to test for statistical significance. RESULTS: The one-year SMR ranged from 3.64 (2.82 - 4.61) to 4.53 (3.67 - 5.54) in men and from 2.78 (2.39 - 3.19) to 3.60 (3.19 - 4.05) in women. In the 0-6 months interval a reduction in SMR from 1978/79 to 1996/97 was observed in women aged ?85 years. The duration of excess mortality ranged from two years in men ?85 years to more than ten years in men and women aged 65-84 years. CONCLUSION: Excess mortality among hip fracture patients remains high. Over the decades, a reduced excess mortality was mainly seen in the oldest patients, suggesting that specific efforts intending to improve prevention and treatment of osteoporosis and osteoporotic fractures in the youngest elderly are required.

Project description:OBJECTIVES:To compare the standardized incidence rates (IRs) of hip fracture for Native Americans versus other racial groups in U.S. nursing homes (NHs). METHODS:We studied Medicare fee-for-service NH residents aged ?65?years who became long-stay (index date) between 1/1/2008 and 12/31/2009 (n?=?1,136,544). Residents were followed from the index date until occurrence of hip fracture, death, Medicare disenrollment, or study end (12/31/2013). We calculated hip fracture IRs by race and used inverse probability weighting to standardize the rates for baseline demographic and clinical characteristics collected from the Minimum Data Set and Medicare claims data. We compared characteristics of NHs used by residents of different races using Online Survey, Certification and Reporting (OSCAR) data. RESULTS:Among long-stay U.S. NH residents, the standardized IR of hip fracture per 100 person-years was highest in Native Americans [2.16; 95% confidence interval (CI) 1.91-2.44] and white residents (2.05; 2.03-2.06), and lowest in black residents (0.82; 0.79-0.85). NHs caring for Native American residents were more likely to be rurally located as compared to other racial group. CONCLUSIONS:In U.S. NHs, Native Americans and whites have the highest standardized IR of hip fracture and should receive particular attention in fracture prevention efforts.
