Abstract The effect of fractures other than hip and spine on HRQoL in younger and older women has not been extensively studied. In a cohort of 86,128 postmenopausal women, we found the impact of recent osteoporosis-related fractures on HRQoL to be similar between women <65 compared with those ,65 years of age. The impact of spine, hip, or rib fractures was greater than that of wrist fractures in both age groups. Introduction: Health-related quality of life (HRQoL) after vertebral and hip fractures has been well studied. Less is known about HRQoL after fractures at other sites. We studied the effect of recent clinical fractures on HRQoL, using Short Form-12 (SF-12). Materials and Methods: This study included 86,128 postmenopausal participants in the National Osteoporosis Risk Assessment (NORA) who responded to two follow-up surveys during a 2-year interval. At each survey, they completed the SF-12 HRQoL questionnaire and reported new fractures of the hip, spine, wrist, and rib. The effect of recent fracture on HRQoL was assessed by comparing Physical Component Score (PCS) and Mental Component Score (MCS) means for women with and without new fractures at the second survey. Analyses were by fracture type and by age group (50,64 and 65,99) and were adjusted for PCS and MCS at the first survey. Results: New fractures (320 hip, 445 vertebral, 657 rib, 835 wrist) occurring during the interval between the first and second follow-up surveys were reported by 2257 women. The PCS was poorer in both older and younger women who had fractured the hip, spine, or rib (p , 0.001). Wrist fractures had an impact on PCS in women ,65 years of age (p < 0.001), but not older women (p > 0.10). These differences in PCS by fracture status were similar to those reported for other chronic diseases such as asthma, chronic obstructive pulmonary disease (COPD), and osteoarthritis. MCS was less consistently changed by fracture status, but younger and older women with vertebral fracture (p < 0.004), older women with hip fracture (p < 0.004), and younger women with rib fracture (p < 0.004) had poorer MCS compared with those who did not fracture within their age cohort. Conclusions: Recent osteoporosis-related fractures have significant impact on HRQoL as measured by SF-12. The impact of recent fracture on HRQoL was similar for older and younger postmenopausal women. Fracture prevention and postfracture interventions that target the subsequent symptoms are needed for postmenopausal women of any age. [source]


Population Trends in BMD Testing, Treatment, and Hip and Wrist Fracture Rates: Are the Hip Fracture Projections Wrong?

JOURNAL OF BONE AND MINERAL RESEARCH, Issue 6 2005
Susan B Jaglal PhD
Abstract A worldwide epidemic of hip fractures has been predicted. Time trends in BMD testing, bone-sparing medications and hip and wrist fractures in the province of Ontario, Canada, were examined. From 1996 to 2001, BMD testing and use of bone-sparing medications increased each year, whereas despite the aging of the population, wrist and hip fracture rates decreased. Introduction: If patients with osteoporosis are being diagnosed and effective treatments used with increasing frequency in the population, rates of hip and wrist fractures will remain stable or possibly decrease. We report here time trends in BMD testing, prescriptions for bone-sparing medications, hip and wrist fracture rates, and population projections of fracture rates to 2005 in the province of Ontario, Canada. Materials and Methods: Ontario residents have universal access to Medicare. To examine time trends in BMD testing, all physician claims for DXA from 1992 to 2001 were selected from the Ontario Health Insurance Plan (OHIP) database. Trends in prescribing were examined from 1996 to 2003 using data from the Ontario Drug Benefit plan, which provides coverage to persons ,65 years of age. Actual numbers of hip and wrist fractures were determined for 1992-2000 and population projections for 2001-2005 using time-series analysis. Wrist fractures were identified in the OHIP database and hip fractures through hospital discharge abstracts. Results: From 1992 to 2001, the number of BMD tests increased 10-fold. There has been a steady increase in the number of persons filling prescriptions for antiresorptives (12,298 in 1996 to 225,580 in 2003) and the majority were for etidronate. For women, the rate of decline for wrist fractures is greater than that for hip fractures. The rate of hip fracture was fairly constant around 41 per 10,000 women ,50 years between 1992 and 1996. In 1997, the hip fracture rate began to decrease, and the population projections suggest that this downward trend will continue to a rate of 33.1 per 10,000 in 2005. Conclusions: Our findings suggest that fracture rates may be on the decline, despite the aging of the population, because of increased patterns of diagnosis and treatment for osteoporosis. [source]


Emergency nurse practitioner care and emergency department patient flow: Case,control study

EMERGENCY MEDICINE AUSTRALASIA, Issue 4 2006
Julie Considine
Abstract Objective:, The present study aimed to compare ED waiting times (for medical assessment and treatment), treatment times and length of stay (LOS) for patients managed by an emergency nurse practitioner candidate (ENPC) with patients managed via traditional ED care. Methods:, A case,control design was used. Patients were selected using the three most common ED discharge diagnoses for ENPC managed patients: hand/wrist wounds, hand/wrist fractures and removal of plaster of Paris. The ENPC group (n = 102) consisted of patients managed by the ENPC who had ED discharge diagnoses as mentioned above. The control group (n = 623) consisted of patients with the same ED discharge diagnoses who were managed via traditional ED care. Results:, There were no significant differences in median waiting times, treatment times and ED LOS between ENPC managed patients and patients managed via traditional ED processes. There appeared to be some variability between diagnostic subgroups in terms of treatment times and ED LOS. Conclusion:, Patient flow outcomes for ENPC managed patients are comparable with those of patients managed via usual ED processes. [source]


Association of the VDR Translation Start Site Polymorphism and Fracture Risk in Older Women,,

JOURNAL OF BONE AND MINERAL RESEARCH, Issue 5 2007
Susan P Moffett PhD
Abstract We evaluated the association between the VDR translation start site polymorphism and osteoporotic phenotypes among 6698 older white women. Women with the C/C genotype had lower wrist BMD and an increased risk of wrist and all non-spine/low-trauma fractures. The high frequency of this variant confers a population attributable risk that is similar to several established risk factors for fracture. Introduction: The vitamin D receptor (VDR) is a nuclear receptor that regulates bone formation, bone resorption, and calcium homeostasis. A common C to T polymorphism in exon 2 of the VDR gene introduces a new translation start site and a protein that differs in length by three amino acids (T = 427aa, C = 424aa; rs10735810). Materials and Methods: We conducted genetic association analyses of this polymorphism, BMD, and fracture outcomes in a prospective cohort of 6698 white American women ,65 years of age. Incident fractures were confirmed by physician adjudication of radiology reports. There were 2532 incident nontraumatic/nonvertebral fractures during 13.6 yr of follow-up including 509 wrist and 703 hip fractures. Results: Women with the C/C genotype had somewhat lower distal radius BMD compared with those with the T/T genotype (CC = 0.358 g/cm2, CT = 0.361 g/cm2, TT = 0.369 g/cm2, p = 0.003). The C/C genotype was also associated with increased risk of non-spine, low traumatic fractures (HR: 1.18; 95% CI: 1.04, 1.33) and wrist fractures (HR: 1.33; 95% CI: 1.01, 1.75) compared with the T/T genotype in age-adjusted models. Further adjustments for distal radius BMD only slightly attenuated these associations. The VDR polymorphism was not associated with hip fracture. The population attributable risk (PAR) of the C/C genotype for incident fractures was 6.1%. The PAR for established risk factors for fracture were: low femoral neck BMD (PAR = 16.3%), maternal history of fracture (PAR = 5.1%), low body weight (PAR = 5.3%), corticosteroid use (PAR = 1.3%), and smoking (PAR = 1.6%). Similar PAR results were observed for wrist fractures. Conclusions: The common and potentially functional VDR translation start site polymorphism confers a modestly increased relative risk of fracture among older white women. However, the high frequency of this variant confers a population attributable risk that is similar to or greater than several established risk factors for fracture. [source]

Effect of Alendronate on the Age-Specific Incidence of Symptomatic Osteoporotic Fractures

JOURNAL OF BONE AND MINERAL RESEARCH, Issue 6 2005
Marc C Hochberg MD
Abstract Analyses of data from 3658 postmenopausal women with osteoporosis enrolled in the Fracture Intervention Trial showed that alendronate is effective in reducing the risk of symptomatic osteoporotic fractures across a spectrum of ages. Introduction: Most osteoporosis studies examine the relative risk of fracture based on the entire duration of treatment. Because older patients tend to be at higher risk for osteoporosis-related fractures, this analysis examined the effect of alendronate treatment on the relative risk of fracture in terms of the age that patients attained during the study. Materials and Methods: We studied 3658 postmenopausal women with osteoporosis 55-80 years of age at baseline enrolled in the Fracture Intervention Trial, a large randomized, double-blind, placebo-controlled study. Patients were treated with placebo or with alendronate at a daily dose of 5 mg for 2 years followed by 10 mg for an additional 1-2.5 years, and monitored for clinical fractures. Age, rather than study time, was the dynamic variable in our analysis. Results: The relative risk reductions for hip, clinical spine, and wrist fractures were constant across age groups, without evidence of a decline at older ages. Specifically, alendronate reduced the risk of clinical fracture by 53% at the hip (relative risk [RR] = 0.47; 95% CI = 0.27-0.81; p < 0.01), 45% at the spine (RR = 0.55; 95% CI = 0.37-0.83; p < 0.01), and 31% at the wrist (RR = 0.69; 95% CI = 0.50-0.98; p = 0.038). In addition, alendronate produced a significant risk reduction of 40% (RR = 0.60; 95% CI = 0.47-0.77; p < 0.01) for the composite event of clinical hip, spine, and wrist fractures. As a consequence of the constant relative risk model, the absolute risk reduction with alendronate treatment increased with age because of the age-related increase in fracture risk in the placebo group. The absolute risk reduction for the composite event (hip, spine, and wrist fractures together) for alendronate treatment versus placebo was 65, 80, 111, and 161 women with fractures per 10,000 PYR for the 55 to <65, 65 to <70, 70 to <75, and 75-85 year age groups, respectively. Conclusions: These data show that alendronate is effective in reducing the risk of symptomatic osteoporotic fractures across a spectrum of ages. The effectiveness is somewhat greater in patients with femoral neck T score , ,2.5 than in those with a T score , ,2.0. [source]


Osteoporosis and Fracture Risk in Women of Different Ethnic Groups

JOURNAL OF BONE AND MINERAL RESEARCH, Issue 2 2005
Elizabeth Barrett-Connor MD
Abstract Osteoporosis and 1-year fracture risk were studied in 197,848 postmenopausal American women from five ethnic groups. Weight explained differences in BMD, except among blacks, who had the highest BMD. One SD decrease in BMD predicted a 50% increased fracture risk in each group. Despite similar relative risks, absolute fracture rates differed. Introduction: Most information about osteoporosis comes from studies of white women. This study describes the frequency of osteoporosis and the association between BMD and fracture in women from five ethnic groups. Materials and Methods: This study was made up of a cohort of 197,848 community-dwelling postmenopausal women (7784 blacks, 1912 Asians, 6973 Hispanics, and 1708 Native Americans) from the United States, without known osteoporosis or a recent BMD test. Heel, forearm, or finger BMD was measured, and risk factor information was obtained; 82% were followed for 1 year for new fractures. BMD and fracture rates were compared, adjusting for differences in covariates. Results: By age 80, more than one-fifth of women in each ethnic group had peripheral BMD T scores <,2.5. Black women had the highest BMD; Asian women had the lowest. Only the BMD differences for blacks were not explained by differences in weight. After 1 year, 2414 new fractures of the spine, hip, forearm, wrist, or rib were reported. BMD at each site predicted fractures equally well within each ethnic group. After adjusting for BMD, weight, and other covariates, white and Hispanic women had the highest risk for fracture (relative risk ,RR' 1.0 ,referent group' and 0.95, 95% CI, 0.76, 1.20, respectively), followed by Native Americans (RR, 0.87; 95% CI, 0.57, 1.32), blacks (RR, 0.52; 95% CI, 0.38, 0.70), and Asian Americans (RR, 0.32; 95% CI, 0.15, 0.66). In age- and weight-adjusted models, each SD decrease in peripheral BMD predicted a 1.54 times increased risk of fracture in each ethnic group (95% CI, 1.48-1.61). Excluding wrist fractures, the most common fracture, did not materially change associations. Conclusions: Ethnic differences in BMD are strongly influenced by body weight; fracture risk is strongly influenced by BMD in each group. Ethnic differences in absolute fracture risk remain, which may warrant ethnic-specific clinical recommendations. [source]


ApoE Gene Polymorphisms, BMD, and Fracture Risk in Elderly Men and Women: The Rotterdam Study,

JOURNAL OF BONE AND MINERAL RESEARCH, Issue 9 2004
Mariette WCJ Schoofs
Abstract To study the association between the ApoE gene polymorphism and osteoporosis, we performed an association study in 5857 subjects from the Rotterdam Study. We did not observe an association between the ApoE polymorphism and osteoporosis in this study, which is thus far the largest study on ApoE and osteoporosis. Introduction: The E4 allele of the E2, E3, E4 protein isoform polymorphism in the gene encoding apolipoprotein E (ApoE) has previously been associated with an increased fracture risk. We investigated the association between the ApoE polymorphism and BMD, bone loss, and incident fractures as part of the Rotterdam Study a prospective population-based cohort study of diseases in the elderly. Materials and Methods: The study population consisted of 5857 subjects (2560 men; 3297 women) for whom data on ApoE genotypes, confounding variables, and follow-up of nonvertebral fractures were available. Data on femoral neck and lumbar spine BMD were available for 4814 participants. Genotype analyses for bone loss (defined as annualized percent change in BMD at the hip and lumbar spine) and BMD were performed using ANOVA. Fractures were analyzed using a Cox proportional-hazards model and logistic regression. All relative risks were adjusted for age and body mass index. Results and Conclusions: The genotype distribution of the study population was in Hardy-Weinberg equilibrium (p = 0.98) and did not differ by gender. At baseline, mean BMD of the lumbar spine and femoral neck did not differ between the ApoE genotypes of men and women. Bone loss (mean follow-up, 2.0 years) did not differ by ApoE genotype for women and men. During a mean follow-up of 6.6 years, 708 nonvertebral fractures (198 hip fractures and 179 wrist fractures) and 149 incident vertebral fractures occurred. No consistent differences in the distribution of alleles could be observed between subjects with or without these fractures. Our data do not support the hypothesis that the ApoE4 risk allele is associated with BMD, increased bone loss, or an increased risk of osteoporotic fractures. [source]


Fractal Analysis of Radiographic Trabecular Bone Texture and Bone Mineral Density: Two Complementary Parameters Related to Osteoporotic Fractures

JOURNAL OF BONE AND MINERAL RESEARCH, Issue 4 2001
C. L. Benhamou
Abstract Trabecular bone microarchitecture and bone mineral density (BMD) are two main factors related to osteoporotic fractures. Currently, however, microarchitecture is not evaluated. We have developed and validated a trabecular bone texture analysis from radiographic images. The objective was to determine if the fractal analysis of texture was able to distinguish osteoporotic fracture groups from control groups, either in vertebrae, hip, or wrist fractures, and to determine if this indicator and BMD were independent and complementary. In this cross-sectional unicenter case-control population study in postmenopausal women, 107 fracture cases were enrolled and age-matched with 197 control cases. This population comprised 40 vertebral fractures (with 70 controls), 30 hip fractures (55 controls), and 37 wrist fractures (62 controls). Hip and lumbar spine BMD were measured by double-energy X-ray absorptiometry. Fractal analysis of texture was performed on calcaneus radiographs and the result was expressed as the H parameter (H = 2-fractal dimension). The H parameter showed a lower value (0.679 ± 0.053 SD) in fracture cases versus control cases (0.696 ± 0.030; p = 0.007), the statistical significance persisting after adjustment for age and for lumbar spine (LS) or hip BMD. This result was confirmed in vertebral fractures (p = 0.0001) and hip fractures (p = 0.003) but not wrist fractures (p = 0.07). We determined the threshold between high and low H values and then the odds ratios (OR) of fracture for low H for BMD , ,2.5 SD in T score and for the combinations of both parameters. The OR of fracture for low H was 1.6 (95% CI, 1.1,2.6). For LS BMD , ,2.5 SD the OR of 6.1 (3.4,10.8) shifted to 9.0 (4.0,20.4) when we added low H and for hip BMD it shifted from 5.6 (3.3,9.4) to 8.1 (4.0,16.8). In vertebral, hip, and wrist fracture cases the results were also significant. These data have shown that the fractal analysis of texture on calcaneus radiographs can distinguish osteoporotic fracture groups from control groups. This analysis and BMD provide independent and complementary information. These data suggest that we can improve the fracture risk evaluation by adding information related to microarchitecture, derived from analysis of conventional radiographic images. [source]
