Development and validation of a discriminative quality of life questionnaire for osteoporosis (the OPTQoL)

Quality of Life and Pain after Proximal Humeral Fractures in the Elderly: A Systematic Review

Background and Objectives: The proximal humeral fracture (PHF) is one of the most common fractures in elderly patients. A PHF might influence the quality of life (QoL) on several different levels, especially in elderly patients, but it is unclear which treatment option results in a better QoL outcome. Therefore, we aimed to systematically review the current literature for studies that have analyzed the QoL and pain of elderly patients treated either surgically or non-operatively for PHF. Materials and Methods: A comprehensive search of the literature was performed in the PubMed database from January to April 2023. Studies describing the QoL or the level of pain of patients older than 60 years with the EuroQoL-5 Dimension (EQ-5D) score or the visual analogue scale (VAS) after the treatment of PHF, either non-operatively (non-OP), with open-reduction and internal fixation using a locking plate (LPF), or with reverse total shoulder arthroplasty (RTSA) were included. Twelve studies were analyzed descriptively and the individual risk of bias was assessed using the ROB2 and ROBINS-I tools. Results: A total of 12 studies with 712 patients at baseline were included (78% female sex, mean age 75.2 years). The reported VAS scores at 12-month follow-up (FU) ranged from 0.7 to 2.5. The calculated overall mean VAS score across all studies showed a decreasing tendency for all treatments, with an increasing FU time up to 12 months after PHF. None of the studies reported any significant differences of the EQ-5D across the groups. The overall calculated EQ-5D indices showed an increasing trend after 6-8 weeks FU, but did not differ significantly between the three treatments. Conclusions: In conclusion, the current literature suggests that there are no clinically important differences between the QoL or pain in elderly patients with PHF after non-operative treatment or surgical treatment with LPF or RTSA. However, the number of studies and level of evidence is rather low and further trials are urgently needed.

Medication holidays in osteoporosis: evidence-based recommendations from the Italian guidelines on 'Diagnosis, risk stratification, and continuity of care of fragility fractures' based on a systematic literature review

BACKGROUND

Noncommunicable, chronic diseases need pharmacological interventions for long periods or even throughout life. The temporary or permanent cessation of medication for a specific period, known as a 'medication holiday,' should be planned by healthcare professionals.

OBJECTIVES

We evaluated the association between continuity (adherence or persistence) of treatment and several outcomes in patients with fragility fractures in the context of the development of the Italian Guidelines.

DESIGN

Systematic review.

DATA SOURCES AND METHODS

We systematically searched PubMed, Embase, and the Cochrane Library up to November 2020 for randomized clinical trials (RCTs) and observational studies that analyzed medication holidays in patients with fragility fracture. Three authors independently extracted data and appraised the risk of bias of the included studies. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation methodology. Effect sizes were pooled in a meta-analysis using random effects models. Primary outcomes were refracture and quality of life; secondary outcomes were mortality and treatment-related adverse events.

RESULTS

Six RCTs and nine observational studies met our inclusion criteria, ranging from very low to moderate quality. The adherence to antiosteoporotic drugs was associated with a lower risk of nonvertebral fracture [relative risk (RR) 0.42, 95% confidence interval (CI) 0.20-0.87; three studies] than nonadherence, whereas no difference was detected in the health-related quality of life. A reduction in refracture risk was observed when continuous treatment was compared to discontinuous therapy (RR 0.49, 95% CI 0.25-0.98; three studies). A lower mortality rate was detected for the adherence and persistence measures, while no significant differences were noted in gastrointestinal side effects in individuals undergoing continuous versus discontinuous treatment.

CONCLUSION

Our findings suggest that clinicians should promote adherence and persistence to antiosteoporotic treatment in patients with fragility fractures unless serious adverse effects occur.

Validity and reliability of smartphone-based Goniometer-Pro app for measuring the thoracic kyphosis

BACKGROUND CONTEXT

It is important to precisely measure thoracic kyphosis while examining the patients and studying effectiveness of therapeutic treatments.

PURPOSE

The present study evaluates validity as well as intra- and inter-rater reliability of health-related Goniometer-Pro android app in measuring thoracic kyphosis.

METHODS

A total number of 31 subjects were examined to validate using markers and measures of the proposed method to mark the spinous process, palpation, and radiologic imaging in the sagittal plane to obtain the thoracic curvature using Cobb method. Moreover, 40 subjects were examined for reliability by applying an evaluator at three occasions with an interval of one week (intra-rater) and three different evaluators at the same place and day (inter-rater).

RESULTS

Findings indicated that there was no significant difference between Cobb angle and the angle from the proposed method in thoracic curvature (p > 0.5). However, significant correlation was observed for the thoracic (r = 0.81, P = 0.000) with an ICC of 0.89. Intra- and inter-rater measurements were significantly correlated.

CONCLUSION

Our proposed method using Goniometer-Pro android app is highly reliable and accurate in determining thoracic curvature values.

Understanding Thoracic Spine Morphology, Shape, and Proportionality

STUDY DESIGN

Retrospective review.

OBJECTIVE

The aim of this study was to describe thoracic kyphosis (TK) in a normal asymptomatic population and to evaluate the association between TK magnitude and its shape.

SUMMARY OF BACKGROUND DATA

Understanding spinal anatomy requires a three-dimensional appreciation of the spine's shape, morphology, and proportions. The customary definition of TK is the angle between T4 and T12. However, little is known on the actual shape of TK in adults.

METHODS

Asymptomatic volunteers were recruited; demographic data along with full-body standing radiographs were recorded. Radiographic data such as T1-12 and T4-12 angles were collected. Maximum TK and vertebral orientation/tilt were also collected, in addition to cumulative TK and Centered Kyphosis at T7. The cohort was stratified by T1-12 value (<40°, 40°-60°, and>60°) and comparisons and regressions were performed afterward.

RESULTS

One hundred nineteen subjects were included (average age 50.8 yrs, 81 female). Mean T1-12 kyphosis was 49.5°, mean T4-12 kyphosis 41.5°, and mean maximum TK was 52.6°. T1 was the most anteriorly tilted vertebra, L1 the most posteriorly tilted; T7 was horizontal, independently of T1-12 value or age. Cumulative kyphosis analysis revealed that the apex of kyphosis was located at T6-T7. Regression analysis predicting the value and the percentage of T1-7 both yielded T1-12 as a predictor (Adj. r = 0.32, Adj. r = 0.13).

CONCLUSION

Changes in kyphosis distribution in an asymptomatic population suggest that TK is not a simple circle arc: with low TK, 2/3 of the kyphosis is located in the upper part and when TK increases, the distribution of kyphosis will be symmetric around T7. It is possible to predict the amount of kyphosis in the upper part using total kyphosis value. This could help estimate preoperative compensation and predict reciprocal change.

Adherence to osteoporosis therapy after an upper extremity fracture: a pre-specified substudy of the C-STOP randomized controlled trial

Despite their proven efficacy for secondary fracture prevention, long-term adherence with oral bisphosphonates is poor.

INTRODUCTION

To compare the effectiveness of two interventions on long-term oral bisphosphonate adherence after an upper extremity fragility fracture.

METHODS

Community-dwelling participants 50 years or older with upper extremity fragility fractures not previously treated with bisphosphonates were randomized to either a multi-faceted patient and physician educational intervention (the active control arm) vs. a nurse-led case manager (the study arm). Primary outcome was adherence (taking > 80% of prescribed doses) with prescribed oral bisphosphonates at 12 months postfracture between groups; secondary outcomes included rates of primary non-adherence and 24-month adherence. We also compared quality of life between adherent and non-adherent patients.

RESULTS

By 12 months, adherence with the initially prescribed bisphosphonate was similar (p = 0.96) in both groups: 38/48 (79.2%) in the educational intervention group vs. 66/83 (79.5%) in the case manager arm. By 24 months, adherence rates were 67% (32/48) in the educational intervention group vs. 53% (43/81) in case managed patients (p = 0.13). Primary non-adherence was 6% (11 patients) in the educational intervention group and 12% (21 patients) in the case managed group (p = 0.07). Prior family history of osteoporosis (aOR 2.1, 95% CI 1.0 to 4.4) and being satisfied with current medical care (aOR 2.3, 95% CI 1.1 to 4.8) were associated with better adherence while lower income (aOR 0.2, 95% CI 0.1 to 0.6, for patients with income < $30,000 per annum) was associated with poorer rates of adherence. There were no differences in health-related quality of life scores at baseline or during follow-up between patients who were adherent and those who were not.

CONCLUSION

While both interventions achieved higher oral bisphosphonate adherence compared to previously reported adherence rates in the general population, primary non-adherence and long-term adherence to bisphosphonates were similar in both arms. Adherence was influenced by family history of osteoporosis, satisfaction with current medical care, and income.

Comparing Strategies Targeting Osteoporosis to Prevent Fractures After an Upper Extremity Fracture (C-STOP Trial): A Randomized Controlled Trial

We compared osteoporosis care after upper extremity fragility fracture using a low-intensity Fracture Liaison Service (FLS) versus a high-intensity FLS in a pragmatic patient-level parallel-arm comparative effectiveness trial undertaken at a Canadian academic hospital. A low-intensity FLS (active-control) that identified patients and notified primary care providers was compared to a high-intensity FLS (case manager) where a specially-trained nurse identified patients, investigated bone health, and initiated appropriate treatment. A total of 361 community-dwelling participants 50 years or older with upper extremity fractures who were not on bisphosphonate treatment were included; 350 (97%) participants completed 6-month follow-up undertaken by assessors blinded to group allocation. The primary outcome was difference in bisphosphonate treatment between groups 6 months postfracture; secondary outcomes included differences in bone mineral density (BMD) testing and a predefined composite measure termed "appropriate care" (taking or making an informed decision to decline medication for those with low BMD; not taking bisphosphonate treatment for those with normal BMD). Absolute differences (%), relative risks (RR with 95% confidence intervals [CIs]), number-needed-to-treat (NNT), and direct costs were compared. A total of 181 participants were randomized to active-control and 180 to case-manager using computer-generated randomization; the groups were similar on study entry. At 6 months, 51 (28%) active-control versus 86 (48%) case-manager participants started bisphosphonate treatment (20% absolute difference; RR 1.70; 95% CI, 1.28 to 2.24; p < 0.0001; NNT = 5). Of active-controls, 108 (62%) underwent BMD testing compared to 128 (73%) case-managed patients (11% absolute difference; RR 1.17; 95% CI, 1.01 to 1.36; p = 0.03). Appropriate care was received by 76 (44%) active-controls and 133 (76%) case-managed participants (32% absolute difference; RR 1.73; 95% CI, 1.43 to 2.09; p < 0.0001). The direct cost per participant was $18 Canadian (CDN) for the active-control intervention compared to $66 CDN for the case-manager intervention. In summary, case-management led to substantially greater improvements in bisphosphonate treatment and appropriate care within 6 months of fracture than the active control. © 2018 American Society for Bone and Mineral Research.

Quality of life assessment in musculo-skeletal health

Musculoskeletal disorders affect morbidity, quality of life and mortality, and represent an increasing economic and societal burden in the context of population aging and increased life expectancy. Improvement of quality of life should be one of the priorities of any interventions to prevent and treat musculoskeletal disorders in the ageing population. Two main approaches, namely generic and disease-specific instruments, can be applied to measure health-related quality of life. Among the generic tools available in scientific literature, the short form 36 questionnaire (SF-36) and the Euroqol five item questionnaire (EQ-5D) are two of the most popular questionnaires used to quantify the health related quality of life in people with musculoskeletal disorders. However, because generic tools may not always be able to detect subtle effects of a specific condition on quality of life, a specific tool is highly valuable. Specific tools improve the ability to clinically characterize quality of life in subjects with a specific musculoskeletal disorder, as well as the capacity to assess changes over time in the QoL of these subjects. The recent development of specific tools should help to validate preventive and therapeutic interventions in this field.

Critical impact of patient knowledge and bone density testing on starting osteoporosis treatment after fragility fracture: secondary analyses from two controlled trials

Most patients are not treated for osteoporosis after their fragility fracture "teachable moment." Among almost 400 consecutive wrist fracture patients, we determined that better-than-average osteoporosis knowledge (adjusted odds = 2.6) and BMD testing (adjusted odds = 6.5) were significant modifiable facilitators of bisphosphonate treatment while male sex, working outside the home, and depression were major barriers.

INTRODUCTION

In the year following fragility fracture, fewer than one quarter of patients are treated for osteoporosis. Although much is known regarding health system and provider barriers and facilitators to osteoporosis treatment, much less is understood about modifiable patient-related factors.

METHODS

Older patients with wrist fracture not treated for osteoporosis were enrolled in trials that compared a multifaceted intervention with usual care controls. Baseline data included a test of patient osteoporosis knowledge. We then determined baseline factors that independently predicted starting bisphosphonate treatment within 1 year.

RESULTS

Three hundred seventy-four patients were enrolled; mean age 64 years, 78 % women, 90 % white, and 54 % with prior fracture. Within 1 year, 86 of 374 (23 %) patients were treated with bisphosphonates. Patients who were treated had better osteoporosis knowledge at baseline (70 % correct vs 57 % for untreated, p < 0.001) than patients who remained untreated; conversely, untreated patients were more likely to be male, still working, and report depression. In fully adjusted models, osteoporosis knowledge was independently associated with starting bisphosphonates (adjusted OR 2.6, 95 %CI 1.3-5.3). Obtaining a BMD test (aOR 6.5, 95 %CI 3.4-12.2) and abnormal BMD results (aOR 34.5, 95 %CI 16.8-70.9) were strongly associated with starting treatment.

CONCLUSIONS

The most important modifiable facilitators of osteoporosis treatment in patients with fracture were knowledge and BMD testing. Specifically targeting these two patient-level factors should improve post-fracture treatment rates.

Dynamic change and influence of osteoporotic back pain with vertebral fracture on related activities and social participation: evaluating reliability and validity of a newly developed outcome measure

The objective of this study was to record the clinical course of osteoporosis over time in Japanese women. We hypothesized that successful control of acute pain associated with osteoporosis will allow better treatment for health-related problems. To confirm this working hypothesis, we developed the Japan Questionnaire for Osteoporotic Pain (JQ22) to measure health status associated with osteoporosis. We examined the validity and reliability of the JQ22 compared with the current gold standard scale for back pain, the Roland Morris questionnaire (RDQ). A total of 125 women who were more than 65 years old, had an acute back pain episode, and had a fragile vertebral fracture confirmed by X-ray and clinical signs, participated in this study. The psychometric analyses for validity and reliability were tested for the JQ22 and the RDQ. The time course up to 6 weeks was observed by investigating both changes in pain characteristics and its influence on related activities and social participation. Cronbach's alpha coefficient was 0.979 and 0.919 for the JQ22 and RDQ, respectively. The Akaike Information Criterion (AIC) indicated that the JQ22 items were separated into four domains, which were sequentially arranged at the baseline and subsequently changed. This structure reflected osteoporotic back characteristics covering a range from pain to social activities. The JQ22 was shown to be a valid and reliable scale for patient-based measurement of osteoporotic back pain. It also revealed both changes in pain characteristics and the influence of pain on related activities and participation.

Reliability and validity of non-radiographic methods of thoracic kyphosis measurement: a systematic review

BACKGROUND

A wide array of instruments are available for non-invasive thoracic kyphosis measurement. Guidelines for selecting outcome measures for use in clinical and research practice recommend that properties such as validity and reliability are considered. This systematic review reports on the reliability and validity of non-invasive methods for measuring thoracic kyphosis.

METHODS

A systematic search of 11 electronic databases located studies assessing reliability and/or validity of non-invasive thoracic kyphosis measurement techniques. Two independent reviewers used a critical appraisal tool to assess the quality of retrieved studies. Data was extracted by the primary reviewer. The results were synthesized qualitatively using a level of evidence approach.

RESULTS

27 studies satisfied the eligibility criteria and were included in the review. The reliability, validity and both reliability and validity were investigated by sixteen, two and nine studies respectively. 17/27 studies were deemed to be of high quality. In total, 15 methods of thoracic kyphosis were evaluated in retrieved studies. All investigated methods showed high (ICC ≥ .7) to very high (ICC ≥ .9) levels of reliability. The validity of the methods ranged from low to very high.

CONCLUSION

The strongest levels of evidence for reliability exists in support of the Debrunner kyphometer, Spinal Mouse and Flexicurve index, and for validity supports the arcometer and Flexicurve index. Further reliability and validity studies are required to strengthen the level of evidence for the remaining methods of measurement. This should be addressed by future research.

Quality of life in sarcopenia and frailty

The reduced muscle mass and impaired muscle performance that define sarcopenia in older individuals are associated with increased risk of physical limitation and a variety of chronic diseases. They may also contribute to clinical frailty. A gradual erosion of quality of life (QoL) has been evidenced in these individuals, although much of this research has been done using generic QoL instruments, particularly the SF-36, which may not be ideal in older populations with significant comorbidities. This review and report of an expert meeting presents the current definitions of these geriatric syndromes (sarcopenia and frailty). It then briefly summarizes QoL concepts and specificities in older populations and examines the relevant domains of QoL and what is known concerning QoL decline with these conditions. It calls for a clearer definition of the construct of disability, argues that a disease-specific QoL instrument for sarcopenia/frailty would be an asset for future research, and discusses whether there are available and validated components that could be used to this end and whether the psychometric properties of these instruments are sufficiently tested. It calls also for an approach using utility weighting to provide some cost estimates and suggests that a time trade-off study could be appropriate.

The impact of asymptomatic vertebral fractures on quality of life in older community-dwelling women: the São Paulo Ageing & Health Study

OBJECTIVES

The aim of this study was to investigate the impact of asymptomatic vertebral fractures on the quality of life in older women as part of the Sao Paulo Ageing & Health Study.

METHODS

This study was a cross-sectional study with a random sample of 180 women 65 years of age or older with or without vertebral fractures. The Quality of Life Questionnaire of the European Foundation for Osteoporosis was administered to all subjects. Anthropometric data were obtained by physical examination, and the body mass index was calculated. Lateral thoracic and lumbar spine X-ray scans were obtained to identify asymptomatic vertebral fractures using a semi-quantitative method.

RESULTS

Women with asymptomatic vertebral fractures had lower total scores [61.4(15.3) vs. 67.1(14.2), p = 0.03] and worse physical function domain scores [69.5(20.1) vs. 77.3(17.1), p = 0.02] for the Quality of Life Questionnaire of the European Foundation for Osteoporosis compared with women without fractures. The total score of this questionnaire was also worse in women classified as obese than in women classified as overweight or normal. High physical activity was related to a better total score for this questionnaire (p = 0.01). Likewise, lower physical function scores were observed in women with higher body mass index values (p<0.05) and lower physical activity levels (p<0.05). Generalized linear models with gamma distributions and logarithmic link functions, adjusted for age, showed that lower total scores and physical function domain scores for the Quality of Life Questionnaire of the European Foundation for Osteoporosis were related to a high body mass index, lower physical activity, and the presence of vertebral fractures (p<0.05).

CONCLUSION

Vertebral fractures are associated with decreased quality of life mainly physical functioning in older community-dwelling women regardless of age, body mass index, and physical activity. Therefore, the results highlight the importance of preventing and controlling asymptomatic vertebral fractures to reduce their impact on quality of life among older women.

Health-related quality of life in patients with osteoporosis in the absence of vertebral fracture: a systematic review

To review whether osteoporosis in the absence of vertebral fracture (VFX) affects health-related quality of life (HRQoL), a systematic search of the main literature databases for HRQoL in patients with osteoporosis without VFX was undertaken. This was undertaken. This identified 1,327 articles as potentially relevant to the review. After screening of abstracts and reviewing 168 articles in detail, 27 were considered relevant. HRQoL data were extracted and collated into tables and, where possible, were converted into normative scores and further analysed. Data relating to the associations between HRQoL and bone mineral density (BMD) were also collated. Of the 27 articles included, only 5 directly compared osteoporosis without VFX with a control group (BMD T-score > -1.0, without VFX). Extracted raw data from 21 articles demonstrated that patients with osteoporosis without VFX had clinically relevant reductions in role physical, general health, vitality, mental health domains and the mental component summary score, using SF36. Using Qualeffo-41, pain and physical function were worse in these patients. Also, HRQoL was related to upper femur, but not lumbar spine BMD. HRQoL data in patients with osteoporosis without VFX are limited and variable but suggest that HRQoL is adversely affected by osteoporosis in the absence of VFX. The association of lower BMD and worse HRQoL suggests that more attention should be paid to HRQoL in those without VFX. Future studies are needed to investigate HRQoL in patients with osteoporosis in the absence of fracture, controlling for co-morbidities and social and economic status.

Quality of life measurements in patients with osteoporosis and fractures

To review all specific questionnaires regarding quality of life in osteoporosis and to describe their distinctive indications, we searched Medline, the Scientific Electronic Library Online database, and the Latin-American and Caribbean Health Sciences Literature database. Nine specific questionnaires related to osteoporosis quality of life were found: 1) the Women's Health Questionnaire, 2) Osteoporosis Quality of Life Questionnaire, 3) Osteoporosis Assessment Questionnaire, 4) Osteoporosis Functional Disability Questionnaire, 5) Quality of Life Questionnaire of the European Foundation for Osteoporosis, 6) Osteoporosis-Targeted Quality of Life Questionnaire, 7) Japanese Osteoporosis Quality of Life Questionnaire, 8) the 16-item Assessment of Health-Related Quality of Life in Osteoporosis, and 9) the Quality of Life Questionnaire in Osteoporosis (QUALIOST™). The Quality of Life Questionnaire of the European Foundation for Osteoporosis is the osteoporosis-specific questionnaire most commonly used in the literature. The Quality of Life Questionnaire of the European Foundation for Osteoporosis and the Osteoporosis Quality of Life Questionnaire are targeted more toward fracture assessment, and the Osteoporosis Functional Disability Questionnaire can be used for longitudinal studies involving exercise. In the present study, the authors summarize all of the specific questionnaires for osteoporosis and demonstrate that these questionnaires should be selected based on the objectives to be evaluated. Osteoporosis-specific quality of life questionnaires should be validated in the language of the country of origin before being used.

Quality of life in postmenopausal women with reduced bone mineral density: psychometric evaluation of the Polish version of QUALEFFO-41

INTRODUCTION

Evaluation of the quality of life of patients with osteoporosis concerns the physical, emotional, social and pain quality of life domains. The aim of the research was to describe the psychometric properties of the Polish version of QUALEFFO-41 in 253 Polish postmenopausal women with osteopenia or osteoporosis and in 132 postmenopausal women with normal BMD.

MATERIAL AND METHODS

The internal reliability of QUALEFFO-41 was studied using Cronbach's alpha coefficient. The reproducibility of the QUALEFFO-41 scales was assessed using Pearson's correlation. The capacity of questions to discriminate between women with reduced bone mineral density (BMD) and normal subjects was assessed by conditional logistic regression to derive an odds ratio with 95% confidence intervals. The discriminative power, which measures the ability of the questionnaire to discriminate between patients, was assessed by clinical validity. Additionally, receiver operating characteristic (ROC) curves were constructed to assess the ability of QUALEFFO-41.

RESULTS

Cronbach's α coefficient reflecting the reliability and repeatability of the instrument for all domains was satisfactory. Results of scores for domains of QUALEFFO-41 and the score for total QUALEFFO-41 demonstrate a significant difference (p < 0.001) among all groups; only in the case of the pain domain was there a significant difference at the level of p < 0.01 between normal subjects and osteoporotic patients. Receiver operating characteristic curve analysis demonstrated a good discriminating capacity of individual domains and total QUALEFFO-41 score.

CONCLUSIONS

The Polish version of QUALEFFO-41 can be used among patients with reduced BMD compared to normal subjects, independently of vertebral fractures, as it is coherent and discriminates well between women with reduced BMD and normal subjects.

Psychometric properties evaluation of the quality of life questionnaire of the European Foundation for Osteoporosis in Arabic population

We aimed to validate QUALEFFO-41 in Arabic language and to examine the use of QUALEFFO-41 in clinical practice for assessing quality of life in patients with vertebral fractures (VF). A total of 201 women were included in the study: 106 (53%) cases with at least one vertebral fracture which had been defined morphometrically and 95 (47%) women with OP or osteopenia and no fractures as a control group. The QUALEFFO was translated into Arabic and applied to case-control pairs with prevalent osteoporotic vertebral fractures to evaluate its reliability, validity, and discriminatory ability. It was also used to evaluate the quality of life (QOL) of case-control with prevalent morphometric fractures. The QOL of all subjects was concurrently assessed using SF-36 for comparison. QUALEFFO-41 had good reliability with adequate convergent and discriminatory validity. There were good correlations between QUALEFFO-41 and SF-36. Subjects with clinical osteoporotic vertebral fractures showed significant impairment of HRQoL on the QUALEFFO compared with controls. Similar results were also observed using the SF-36. ROC curve analysis revealed that QUALEFFO-41 had significant ability to discriminate between morphometric fracture subjects versus and controls. The QUALEFFO discriminates for pain (P = 0.002), physical function (P < 0.0001), social function (P = 0.04), general health (P = 0.001), and mental function (P = 0.01), whereas the SF-36 discriminates exclusively for physical function (P = 0.01) and social function (P = 0.02). The Moroccan Arabic version of the QUALEFFO is a reliable and valid instrument that can be administered to Arabic patients suffering from vertebral fracture osteoporosis to evaluate their quality of life. Its measurement properties were comparable with versions in other languages. In addition, the quality of life measured by QUALEFFO is decreased in patients with vertebral fracture due to OP.

Impact of osteoporosis and vertebral fractures on quality-of-life. a population-based study in Valencia, Spain (The FRAVO Study)

Background

To describe the health related quality of life in a population sample of postmenopausal women over the age of 50 and resident in the city of Valencia (Spain), according to the presence/absence of osteoporosis and the severity of prevalent morphometric vertebral fractures.

Methods

A cross-sectional age-stratified population-based sample of 804 postmenopausal women of 50 years of age and older were assessed with the SF-12 questionnaire. Information about demographic features, lifestyle, clinical features, educational level, anti-osteoporotic and other treatments, comorbidities and risk factors for osteoporosis were collected using an interviewer-administered questionnaire and densitometric evaluation of spine and hip and spine x-rays were carried out.

Results

In the non-adjusted analysis, mild and moderate-severe vertebral fractures were associated with decreased scores in the SF-12 Physical Component Summary (PCS) but not in the Mental Component Summary (MCS), while densitometric osteoporosis with no accompanying fracture was not associated with a worse health related quality of life. In multivariate analysis worse PCS scores were associated to the age groups over 70 (-2.43 for 70-74 group and -2.97 for 75 and older), chronic conditions (-4.66, -6.79 and -11.8 according to the presence of 1, 2 or at least 3 conditions), obesity (-5.35), peripheral fracture antecedents (-3.28), hypoestrogenism antecedents (-2.61) and the presence of vertebral fracture (-2.05).

Conclusions

After adjusting for confounding factors, the physical components of health related quality of life were significantly lower in women with prevalent osteoporotic vertebral fractures than in women -osteoporotic or not- without vertebral fractures.

Nurse case-manager vs multifaceted intervention to improve quality of osteoporosis care after wrist fracture: randomized controlled pilot study

Few outpatients with fractures are treated for osteoporosis in the years following fracture. In a randomized pilot study, we found a nurse case-manager could double rates of osteoporosis testing and treatment compared with a proven efficacious quality improvement strategy directed at patients and physicians (57% vs 28% rates of appropriate care).

INTRODUCTION

Few patients with fractures are treated for osteoporosis. An intervention directed at wrist fracture patients (education) and physicians (guidelines, reminders) tripled osteoporosis treatment rates compared to controls (22% vs 7% within 6 months of fracture). More effective strategies are needed.

METHODS

We undertook a pilot study that compared a nurse case-manager to the multifaceted intervention using a randomized trial design. The case-manager counseled patients, arranged bone mineral density (BMD) tests, and prescribed treatments. We included controls from our first trial who remained untreated for osteoporosis 1-year post-fracture. Primary outcome was bisphosphonate treatment and secondary outcomes were BMD testing, appropriate care (BMD test-treatment if bone mass low), and costs.

RESULTS

Forty six patients untreated 1-year after wrist fracture were randomized to case-manager (n = 21) or multifaceted intervention (n = 25). Median age was 60 years and 68% were female. Six months post-randomization, 9 (43%) case-managed patients were treated with bisphosphonates compared with 3 (12%) multifaceted intervention patients (relative risk [RR] 3.6, 95% confidence intervals [CI] 1.1-11.5, p = 0.019). Case-managed patients were more likely than multifaceted intervention patients to undergo BMD tests (81% vs 52%, RR 1.6, 95%CI 1.1-2.4, p = 0.042) and receive appropriate care (57% vs 28%, RR 2.0, 95%CI 1.0-4.2, p = 0.048). Case-management cost was $44 (CDN) per patient vs $12 for the multifaceted intervention.

CONCLUSIONS

A nurse case-manager substantially increased rates of appropriate testing and treatment for osteoporosis in patients at high-risk of future fracture when compared with a multifaceted quality improvement intervention aimed at patients and physicians. Even with case-management, nearly half of patients did not receive appropriate care.

Community based intervention to optimize osteoporosis management: randomized controlled trial

Background

Osteoporosis-related fractures are a significant public health concern. Interventions that increase detection and treatment of osteoporosis are underutilized. This pragmatic randomised study was done to evaluate the impact of a multifaceted community-based care program aimed at optimizing evidence-based management in patients at risk for osteoporosis and fractures.

Methods

This was a 12-month randomized trial performed in Ontario, Canada. Eligible patients were community-dwelling, aged ≥55 years, and identified to be at risk for osteoporosis-related fractures. Two hundred and one patients were allocated to the intervention group or to usual care. Components of the intervention were directed towards primary care physicians and patients and included facilitated bone mineral density testing, patient education and patient-specific recommendations for osteoporosis treatment. The primary outcome was the implementation of appropriate osteoporosis management.

Results

101 patients were allocated to intervention and 100 to control. Mean age of participants was 71.9 ± 7.2 years and 94% were women. Pharmacological treatment (alendronate, risedronate, or raloxifene) for osteoporosis was increased by 29% compared to usual care (56% [29/52] vs. 27% [16/60]; relative risk [RR] 2.09, 95% confidence interval [CI] 1.29 to 3.40). More individuals in the intervention group were taking calcium (54% [54/101] vs. 20% [20/100]; RR 2.67, 95% CI 1.74 to 4.12) and vitamin D (33% [33/101] vs. 20% [20/100]; RR 1.63, 95% CI 1.01 to 2.65).

Conclusions

A multi-faceted community-based intervention improved management of osteoporosis in high risk patients compared with usual care.

A multi-dimensional questionnaire quantifying quality of life in elderly osteoporotic women: the Italian triple-Q osteoporosis study

BACKGROUND AND AIMS

In advanced age, the influence of vertebral fractures on quality of life extends well beyond the usual sequelae of osteoporosis. In order to intercept older subjects' distress associated with the clinical, functional, social and psychological consequences of the disease, we developed and validated a multidimensional instrument (the triple-Q questionnaire) tailored to older women with osteoporotic fractures. We also examined specific aspects of the questionnaire correlated with bone mineral density.

METHODS

100 osteoporotic women with vertebral fractures and 100 controls aged >65 years, underwent a thorough examination, which also included X-ray of the thoraco-lumbar spine, hip densitometry, the triple-Q questionnaire, and five referral instruments evaluating function, cognition, perception of general health, mood and pain.

RESULTS

The questionnaire was repeatable and able to discriminate between older women with and without vertebral fractures. There was a strong association between referral instrument scores and the corresponding single domain score of the questionnaire. Femoral BMD was also associated with scores indicating fear of falling, fear of fracture, and pain.

CONCLUSIONS

The questionnaire intercepted the influence of osteoporosis on the quality of life of elderly women with vertebral fractures. Subjects who suffered from severe pain and were more fearful of falling were most likely to be severely osteoporotic.

Community pharmacist-initiated screening program for osteoporosis: randomized controlled trial

SUMMARY

This study evaluated the effect of a multifaceted intervention (screening and patient education) by community pharmacists on testing or treatment of osteoporosis. One hundred and twenty-nine patients randomized to receive the intervention were compared to 133 patients who did not receive the intervention. Twice as many patients who got the intervention received further testing or treatment for osteoporosis.

INTRODUCTION

The objective of this study was to determine the effect of a community pharmacist screening program on testing and treatment of osteoporosis.

METHODS

In this randomized, controlled trial, 262 patients meeting bone mineral density (BMD) testing guidelines [men or women aged > or = 65 years or 50-64 years with one major risk factor including previous fracture, family history of osteoporosis, glucocorticoids for > 3 months, or early menopause] were allocated to intervention (129) or control (133). Intervention consisted of printed materials, education, and quantitative ultrasound. Primary outcome was a composite endpoint of BMD or prescription for osteoporosis medication within 4 months.

RESULTS

Primary endpoint of BMD or osteoporosis treatment was achieved by 28 intervention patients (22%) compared with 14 controls (11%) (RR 2.1, 95% CI 1.1-3.7). This was driven by BMD testing (28 (22%) vs. 13 (10%) for controls, p = 0.011). Calcium intake increased more among intervention patients than controls (30% vs. 19%, RR 1.6, 95% CI 1.0-2.5). There was no effect on knowledge or quality of life.

CONCLUSION

A pharmacist screening program doubled the number of patients tested for osteoporosis. Nevertheless, many patients eligible for BMD did not receive appropriate care suggesting more intensive interventions are needed.

Validation of the Japanese Osteoporosis Quality of Life Questionnaire

The Japanese Society for Bone and Mineral Research developed the Japanese Osteoporosis Quality of Life Questionnaire (JOQOL) to evaluate the disease-specific Health-Related QOL, which is specific for osteoporosis of Japanese patients. JOQOL was revised in 2000; it consisted of 38 items with the scale graded from 0 to 4 and a total full score of 152. To elucidate the reliability and validity of the revised JOQOL, we enrolled 193 postmenopausal women as subjects and diagnosed them as having osteoporosis or osteopenia. The mean age of the subjects was 68.2 +/- 8 years; 58 subjects (30.1%) had at least one vertebral fracture. Among them, 83 patients were retested for reliability. The mean lapse from the time of test to that of retest was 23.7(+/- 9.5) days. The subjects were questioned using the JOQOL, Medical Outcomes Study Short Form 36 (SF-36), along with questions on subjects' characteristics and their ADL. The JOQOL scores at the test and the retest were significantly correlated (r = 0.973) without significant difference between their mean scores. All the JOQOL items showed significant correlations at the test and the retest (Kendall's tau = 0.599-0.947). Cronbach's alpha coefficient of JOQOL was 0.918. These results proved the high reliability of JOQOL. The JOQOL score showed negative correlation with age (r = -0.183). The subjects with vertebral fractures had significantly lower JOQOL scores than the subjects without fractures. The JOQOL showed a significant correlation with all the scores in each domain of eight of SF-36 (r = 0.350-0.839). These results were consistent with that of the preceding study. It is concluded that the reliability and the validity of JOQOL were demonstrated in this study.

Health-related quality of life among patients with postmenopausal osteoporosis treated with weekly and monthly bisphosphonates

OBJECTIVE

The present study was designed to assess the effect of monthly ibandronate on health-related quality of life (HR-QoL) in patients with postmenopausal osteoporosis previously treated with weekly bisphosphonates.

METHODS

HR-QoL was assessed by Euroqol (EQ-5D) and Osteoporosis Targeted Quality of Life (OPTQoL) questionnaires.

RESULTS

The EQ-5D questionnaire showed significant improvement associated with ibandronate treatment, occurring in mobility (p < 0.01), usual activity (p < 0.01), pain/discomfort (p < 0.05), and anxiety/depression (p < 0.05). In addition, ibandronate treatment considerably improved patients' perceived health on a visual analog scale (p < 0.001). For the OPTQoL questionnaire, patients reported less physical difficulty (p < 0.001), fewer adaptations in their lives (p < 0.001), and less fear (p < 0.001) with ibandronate than with weekly bisphosphonates.

CONCLUSION

The study demonstrated that patients who were transferred from weekly bisphosphonates to a monthly ibandronate experienced improved HR-QoL.

Morphometric vertebral fractures of the lower thoracic and lumbar spine, physical function and quality of life in men

The epidemiology and sequelae of morphometric vertebral fracture (MVF) are poorly documented. We found that MVFs of the lower thoracic and lumbar spine were associated with poor quality of life and impaired physical function in men. We recommend that morphometric X-ray absorptiometry be included in routine requests for bone densitometry.

INTRODUCTION

Vertebral fractures are sentinel events for osteoporosis. We aimed to compare quality of life and physical function in men with and without MVF.

METHODS

Using morphometric X-ray absorptiometry (T10-L4), MVFs were identified in a random sample of men aged 20-93 years. Moderate and severe wedge, biconcave or compression deformities (>25% reduction in any vertebral height) were classified as MVFs.

RESULTS

Of 1,147 men, MVFs were identified in 64. No MVFs were detected for men in their twenties. Prevalence was 1.5% for 30-39 years, 1.4% 40-49 years, 3.2% 50-59 years, 4.7% 60-69 years, 10.0% 70-79 years and 14.6% 80+ years. Among 555 men aged 60+ years, those with MVFs were twice as likely to have quality of life scores in the lowest tertile (age-adjusted OR = 2.35, 95%CI 1.24-4.45). MVFs were associated with lower mean age-adjusted physical activity scores [11.3 (95%CI 9.0-13.8) vs 14.0 (13.2-14.9), P = 0.04] and longer mean age-adjusted 'Up-&-Go' times [9.5 (8.9, 10.1) vs 8.9 (8.8, 9.1) s, P = 0.06].

CONCLUSION

Despite most men being unaware of their condition, MVFs were associated with poor quality of life and impaired physical function. We recommend that morphometric X-ray absorptiometry be included in routine requests for bone densitometry because detection of MVFs has important implications for osteoporosis management in men.

Factors influencing quality of life in Moroccan postmenopausal women with osteoporotic vertebral fracture assessed by ECOS 16 questionnaire

OBJECTIVE

The aim of the study was to evaluate factors influencing quality of life (QOL) in Moroccan postmenopausal women with osteoporotic vertebral fracture assessed by the Arabic version of ECOS 16 questionnaire.

METHODS

357 postmenopausal women were included in this study. The participants underwent bone mineral density (BMD) measurements by DXA of the lumbar spine and the total hip as well as X-ray examination of the thoraco-lumbar spine to identify subclinical vertebral fractures. Patients were asked to complete a questionnaire on clinical and sociodemographic parameters, and osteoporosis risk factors. The Arabic version of the ECOS16 (Assessment of health related quality of life in osteoporosis questionnaire) was used to assess quality of life.

RESULTS

The mean age was 58 +/- 7.8 years, and the mean BMI was 28.3 +/- 4.8 kg/m2. One hundred and eight women (30.1%) were osteoporotic and 46.7% had vertebral fractures. Most were categorized as Grade1 (75%). Three independent factors were associated with a poor quality of life: low educational level (p = 0,01), vertebral fracture (p = 0,03), and history of peripheral fracture (p = 0,006). Worse QOL was observed in the group with vertebral fracture in all domains except "pain": Physical functioning (p = 0,002); Fear of illness (p = 0,001); and Psychosocial functioning (p = 0,007). The number of fractures was a determinant of a low QOL, as indicated by an increased score in physical functioning (p = 0,01), fear of illness (p = 0,007), and total score (p = 0,01) after adjusting on age and educational level. Patients with higher Genant score had low QOL in these two domains too (p = 0,002; p = 0,001 respectively), and in the total score (p = 0,01) after adjusting on age and educational level.

CONCLUSION

Our current data showed that the quality of life assessed by the Arabic version of the ECOS 16 questionnaire is decreased in post menopausal women with prevalent vertebral fractures, with the increasing number and the severity of vertebral fractures.

Preference for weekly and monthly bisphosphonates among patients with postmenopausal osteoporosis: results from the Croatian PROMO Study

The PROMO (preference for once monthly bisphosphonate) Study, conducted in seven hospital centres in Croatia between June 2007 and June 2008, was designed to analyse patient preference for weekly and monthly bisphosphonates in everyday clinical practice where the significant proportion of patients are not completely satisfied with the current osteoporosis treatment. Eligible participants were women with postmenopausal osteoporosis taking weekly bisphosphonates for the last 6 months. Those who agreed to be enrolled were transferred from weekly to monthly ibandronate for the next 6 months. There was no washout period between the two treatment regimens. At the baseline, patients expressed their satisfaction with the weekly treatment. At the end of the study, all patients were asked to complete the five-question survey specially designed for this study. Study population comprised 258 participants. Among 248 patients who completed the study, 244 (98.4%) declared their preference for one of the regimens or they had no preference. Once-monthly regimen was preferred by 231 patients (94.7%), whereas once-weekly regimen was preferred by five patients (2.0%). Eight patients (3.3%) indicated no preference. Furthermore, 93.0% of patients thought that monthly dosing was more convenient. Compared to weekly regimen, monthly dosing was associated with significantly higher satisfaction with the treatment and with significantly less adverse events. In line with these data, 85.9% of patients stated improved quality of life with monthly ibandronate. In summary, the PROMO Study demonstrated strong patient preference for monthly over weekly dosing which is expected to improve suboptimal adherence to weekly bisphosphonates.

Community-based randomised controlled trial evaluating falls and osteoporosis risk management strategies

Background

Osteoporosis-related fractures are a significant public health concern. Interventions that increase detection and treatment of osteoporosis, as well as prevention of fractures and falls, are substantially underutilized. This paper outlines the protocol for a pragmatic randomised trial of a multifaceted community-based care program aimed at optimizing the evidence-based management of falls and fractures in patients at risk.

Design

6-month randomised controlled study.

Methods

This population-based study was completed in the Algoma District of Ontario, Canada a geographically vast area with Sault Ste Marie (population 78 000) as its main city. Eligible patients were allocated to an immediate intervention protocol (IP) group, or a delayed intervention protocol (DP) group. The DP group received usual care for 6 months and then was crossed over to receive the interventions. Components of the intervention were directed at the physicians and their patients and included patient-specific recommendations for osteoporosis therapy as outlined by the clinical practice guidelines developed by Osteoporosis Canada, and falls risk assessment and treatment. Two primary outcomes were measured including implementation of appropriate osteoporosis and falls risk management. Secondary outcomes included quality of life and the number of falls, fractures, and hospital admissions over a twelve-month period. The patient is the unit of allocation and analysis. Analyses will be performed on an intention to treat basis.

Discussion

This paper outlines the protocol for a pragmatic randomised trial of a multi-faceted, community-based intervention to optimize the implementation of evidence based management for patients at risk for falls and osteoporosis.

Multifaceted intervention to improve diagnosis and treatment of osteoporosis in patients with recent wrist fracture: a randomized controlled trial

BACKGROUND

Older patients who experience a fragility fracture are at high risk of future fractures but are rarely tested or treated for osteoporosis. We developed a multifaceted intervention directed at older patients with wrist fractures (in the form of telephone-based education) and their physicians (in the form of guidelines endorsed by opinion leaders, supported by reminders) to improve the quality of osteoporosis care.

METHODS

In a randomized controlled trial with blinded ascertainment of outcomes, we compared our intervention with usual care (provision of printed educational materials to patients). Eligible patients were those older than 50 years of age who had experienced a wrist fracture and were seen in emergency departments and fracture clinics; we excluded those who were already being treated for osteoporosis. The primary outcome was bisphosphonate treatment within 6 months after the fracture. Secondary outcomes included bone mineral density testing, "appropriate care" (consisting of bone mineral density testing with treatment if bone mass was low) and quality of life.

RESULTS

We screened 795 patients for eligibility and randomly assigned 272 to the intervention (137 patients) or control (135 patients) group. The median age was 60 years; 210 (77%) of the subjects were women, and 130 (48%) reported a previous fracture as an adult. Six months after the fracture, 30 (22%) of the intervention patients, as compared with 10 (7%) of the control patients, were receiving bisphosphonate therapy for osteoporosis (adjusted relative risk [RR] 2.6, 95% confidence interval [CI] 1.3-5.1, p = 0.008). Intervention patients were more likely than control patients to undergo bone mineral density testing (71/137 [52%] v. 24/135 [18%]; adjusted RR 2.8, 95% CI 1.9-4.2, p < 0.001) and to receive appropriate care (52/137 [38%] v. 15/135 [11%]; adjusted RR 3.1, 95% CI 1.8-5.3, p < 0.001). There were no differences between the groups in other outcomes. One patient died, and 4 others experienced recurrent fracture.

INTERPRETATION

A multifaceted intervention directed at high-risk patients and their physicians substantially increased rates of testing and treatment for osteoporosis. Nevertheless, more than half of the patients in the intervention group were not receiving appropriate care 6 months after their fracture, which suggests that additional strategies should be explored. (ClinicalTrials.gov trial register no. NCT00152321.).

Cultural adaptation and validation of the Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO) in a Mexican population

Measuring quality of life (QOL) is important, but to date, questionnaires to measure QOL in Mexican patients with osteoporosis (OP) have not been validated. A study was carried out to culturally adapt and validate the Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO) in a Mexican population. Interviews were performed with 160 women, 80 patients with at least one vertebral fracture, and 80 patients with OP as determined by the World Health Organization criteria. Several cultural modifications were made to the Spanish version of the QUALEFFO. Content validity was assessed by a group of experts, and a pilot study was undertaken. At the same time, the Spanish version of the Short Form 36 (Medical Outcomes Study) was applied. The mean age of patients was 71.9 +/- 11.1. The QOL questionnaire showed a test-retest reproducibility (R (i) = 0.94) and internal consistency (alpha = 0.92), while social function scored low (alpha = 0.46). Concurrent validity was significant (r = -0.837, p < 0.001). Significant differences were found between the two groups for pain (p < 0.05), physical function (p < 0.01), social function (p < 0.01), mental function (p < 0.05), and number of fractures (p < 0.001). Discriminatory characteristics between the groups were significant for physical (p < 0.001), social (p < 0.001), and mental (p < 0.02) function. The cultural adaptation of the QUALEFFO was consistent, homogenous, and discriminative. It also showed deterioration in the QOL group of Mexicans with vertebral fractures. The QUALEFFO can be used in a Mexican population to measure the QOL in patients with vertebral fractures after some cultural modifications to take into account local sensibilities.

Prevalence and impact of osteoarthritis and osteoporosis on health-related quality of life among active subjects

BACKGROUND AND AIMS

To assess the prevalence and impact of osteoarthritis (OA) and osteoporosis (OP) on health-related quality of life (HRQOL) among active subjects employed in the public workforce in Belgium.

METHODS

A cohort of 3440 subjects employed by the Liège City Council was prospectively followed for 6 months. The employees were asked to fill in a monthly log in a health record book, of data regarding their healthcare consumption due to OA and OP. HRQOL was assessed using the Medical Outcomes Study Short Form-36 (SF-36).

RESULTS

1811 subjects (52.6%) filled in at least one questionnaire. The mean duration of follow-up was 3.46 months. The self-reported prevalence of OA and OP at entry to the study were respectively 34.1% and 5.3%. 3.6% of subjects reported suffering from both OA and OP. Subjects with OA and both OA and OP had significantly lower scores on all SF-36 dimensions compared with normal subjects, reflecting a worse HRQOL. The OP group had significantly lower mean scores for physical functioning and pain compared with controls. Subjects with both OA and OP had significantly lower values for physical functioning, physical role and pain when compared with the OA and OP groups.

CONCLUSIONS

The results of this survey of a large sample of active subjects show that self-reported osteoarthritis and osteoporosis are common in the workplace. Both diseases have a major impact on health-related quality of life compared with that of people without self-reported musculoskeletal diseases.

Application of a triage approach to peripheral bone densitometry reduces the requirement for central DXA but is not cost effective

A method proffered for the interpretation of measurements from peripheral dual energy X-ray absorptiometry (pDXA) is a triage approach to stratify patients into one of three risk categories; (i) high-treat, (ii) medium-refer for central DXA and (iii) low-reassure. The aim of this study was to apply the triage approach to measures from peripheral scanners and risk indices and stratify patients into one of three risk categories (i), (ii) or (iii). 207 post-menopausal women had central DXA from which they were categorised as non-osteoporotic or osteoporotic. Additional peripheral scans of the left calcaneus were performed on three scanners (GE Lunar Achilles and PIXI, McCue CubaClinical). From demographic details four risk indices were calculated and algorithms combining measures from peripheral scanners and one risk index were obtained. All peripheral measures, risk indices and combination algorithms were good at identifying women at risk of osteoporosis (ROC areas: 0.67-0.82). Each tool stratified varying numbers of osteoporotic and non-osteoporotic women into each risk category using the triage approach. One combination algorithm (PIXI & osteoporosis indices of risk (OSIRIS)) performed best by minimising misclassification (10% non-osteoporotic, 10% osteoporotic) and reducing requirement for central DXA to 36%. However the cost of implementing the triage approach for PIXI & OSIRIS was greater (263%) than central DXA (100%) scanning all women. Although the triage approach was an effective tool at identifying women at risk of osteoporosis the unnecessary treatment of non-osteoporotic women in the high risk category make it impractical. Therefore an alternative more cost-effective method has been suggested.

Issues in conducting cross-cultural research: implementation of an agreed international protocol [corrected] designed by the WHOQOL Group for the conduct of focus groups eliciting the quality of life of older adults

Multi-centre and cross-cultural research require the use of common protocols if the results are to be either pooled or compared. All too often adherence to protocols is not discussed in reports and where it is reported poor adherence is frequently noted. This paper discusses the use of international guidelines developed by WHOQOL Field Centres to conduct and report focus groups aimed at eliciting key concepts of quality of life among older adults. This was the first step in the development of the WHOQOL-OLD instrument. Although there was overall adherence to the agreed guidelines, there were some differences in the level of reporting, even after participating Field Centres had the opportunity to explain their reports. The reasons for these discrepancies are reported. It is concluded that because of local situations, it is difficult to achieve identical implementation of multi-centre cross-cultural protocols and that the highest standards of auditing are required if findings are to be compared. Suggestions for how such protocols can be improved are given.

Psychometric evaluation of the Osteoporosis Patient Treatment Satisfaction Questionnaire (OPSAT-Q), a novel measure to assess satisfaction with bisphosphonate treatment in postmenopausal women

Background

The Osteoporosis Patient Satisfaction Questionnaire (OPSAT-Q) is a new measure of patient satisfaction with bisphosphonate treatment for osteoporosis. The objective of this study was to evaluate the psychometric characteristics of the OPSAT-Q.

Methods

The OPSAT-Q contains 16 items in four subscales: Convenience, Confidence with Daily Activities, Side Effects, and Overall Satisfaction. All four subscale scores and an overall composite satisfaction score (CSS) can be computed. The OPSAT-Q, Osteoporosis Targeted Quality of Life (OPTQoL), and sociodemographic/clinical questionnaires, including 3 global items on convenience, functioning and side effects, were self-administered to women with osteoporosis or osteopenia recruited from four US clinics. Analyses included item and scale performance, internal consistency reliability, reproducibility, and construct validity. Reproducibility was measured using the intraclass correlation coefficient (ICC) via a follow-up questionnaire completed by participants 2 weeks post baseline.

Results

104 women with a mean age of 65.1 years participated. The majority were Caucasian (64.4%), living with someone (74%), and not currently employed (58.7%). 73% had osteoporosis and 27% had osteopenia. 80% were taking weekly bisphosphonates and 18% were taking daily medication (2% missing data). On a scale of 0–100, individual patient subscale scores ranged from 17 to 100 and CSS scores ranged from 44 to 100. All scores showed acceptable internal consistency reliability (Cronbach's alpha > 0.70) (range 0.72 to 0.89). Reproducibility ranged from 0.62 (Daily Activities) to 0.79 (Side Effects) for the subscales; reproducibility for the CSS was 0.81. Significant correlations were found between the OPSAT-Q subscales and conceptually similar global measures (p < 0.001).

Conclusion

The findings from this study confirm the validity and reliability of the OPSAT-Q and support the proposed composition of four subscales and a composite score. They also support the use of the OPSAT-Q to examine the impact of bisphosphonate dosing frequency on patient satisfaction.

Impact of recent fracture on health-related quality of life in postmenopausal women

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 > or = 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 < or = 0.001). Wrist fractures had an impact on PCS in women < or = 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.

Educational intervention to reduce falls and fear of falling in patients after fragility fracture: results of a controlled pilot study

OBJECTIVES

Falls and fear of falling are a major health problem. We sought to determine the effectiveness of an educational intervention in reducing fear of falling and preventing recurrent falls in community-dwelling patients after a fragility fracture.

METHODS

One hundred two community-dwelling patients aged 50 years or older who fell and sustained a wrist fracture and were treated at Emergency Departments in Edmonton, Alberta, Canada (2001-2002) were allocated to either standardized educational leaflets and post-discharge telephone counseling regarding fall prevention strategies ("intervention") or attention-controls ("controls"). Main outcomes were fear of falling and recurrent falls 3 months after fracture.

RESULTS

Mean age was 67 years and most patients were female (80%). The majority of falls (76%) leading to fracture occurred outdoors. Three months post-fracture, almost half of patients (48%) reported increased fear of falling and 11 of 102 (11%) reported falling again. The intervention did not reduce the fear of falling (43% had increased fear vs. 53% of controls, adjusted P value=0.55) or decrease recurrent falls (17% fell vs. 5% of controls, adjusted P value=0.059) within 3 months of fracture.

CONCLUSIONS

An educational intervention undertaken in the Emergency Department was no more effective than usual care in reducing fear of falling or recurrent falls in community-dwelling patients. Future strategies must address a number of dimensions beyond simple education.

Both resistance and agility training reduce back pain and improve health-related quality of life in older women with low bone mass

The purpose of the study was to compare the effects of three different types of group-based exercise programs (resistance training, agility training and general stretching) on back pain and health-related quality of life in older (aged 75-85 years) community-dwelling women with low bone mass (i.e., osteopenia or osteoporosis). The design was a 25-week randomized controlled trial. Participating were 98 community-dwelling women with low bone mass between the ages of 75 to 85 years old. We assessed back pain and its related disability and health-related quality of life. All three types of group-based exercise programs significantly reduced back pain and its related disabilities, but only resistance and agility training significantly improved health-related quality of life in community-dwelling older women with low bone mass. Baseline physical activity level and class attendance were significant predictors of change in health-related quality of life. Change in back pain and its related disabilities after 25 weeks of exercise intervention was significantly correlated with change in health-related quality of life and changes in the domains of pain and physical function. Resistance and agility training significantly enhanced health-related quality of life and may have done so by increasing social interactions and support, enhancing self-efficacy of physical abilities and modifying the experience of back pain. These data provide valuable insight into the specifics of exercise prescription for older women with low bone mass. Future studies may wish to use individualized quality of life measures to further delineate the effects of different types of exercise on quality of life in older adults with low bone mass.

Quality of life in patients with osteoporosis

Complaints regarding, and morbidity of, osteoporosis are caused by fractures which are associated with pain and decrease of physical function, social function, and well-being. These are aspects of quality of life. Health-related quality of life covers physical, mental, and social well-being. Quality of life may be measured for evaluation of treatment effects in clinical trials, for the assessment of the burden of the disease of osteoporosis, and for estimates of the cost-effectiveness of different treatment scenarios in health care policy. Quality of life has been measured in patients with osteoporosis with generic questionnaires such as SF-36 and EQ-5D, which can be used in many diseases, or with one of the six available osteoporotic-specific questionnaires, e.g., Qualeffo-41 or OPAQ. Every questionnaire has to be validated to assess psychometric properties and discrimination power between patients with osteoporosis and control subjects. The value attached to specific health states (utility) can be assessed with some generic instruments or by systematic questioning of the patient, e.g., the time-trade-off method. This results in one value for health status ranging from 0 (death) to 1 (perfect health). Utility values can be used to calculate loss of quality-adjusted life years (QALY). Most data have been obtained in patients with prevalent vertebral fractures. Scores of specific and generic questionnaires showed significant loss of quality of life with prevalent vertebral fractures. In addition, studies with Qualeffo-41 and OPAQ showed a deteriorating quality of life with increasing number of vertebral fractures. Lumbar fractures had more impact on quality of life than thoracic fractures. Incident vertebral fractures were also associated with a decrease of quality of life especially in the physical function domain. This applied to clinical incident vertebral fractures as well as to subclinical fractures to a lesser degree. Loss of quality of life following hip fracture has been documented with generic and osteoporosis-specific questionnaires. A considerable loss was observed in the 1st year with some improvement in the 2nd year, but not to baseline values. Quality of life depended on comorbidity, mobility, activities of daily life (ADL)-independence, and fracture complaints. Utility loss has been observed following hip fracture, especially disabling hip fracture, hip and vertebral fracture combined, or multiple vertebral fractures. Utility following osteoporotic fractures has been valued by patients, the healthy elderly, and panels of experts. The healthy elderly gave the worse quality-of-life scores (lower utility) to various hip fractures than patients with hip fractures themselves. In conclusion, suitable instruments exist for measuring quality of life in patients with osteoporotic fractures. These instruments are useful for clinical trials and for assessment of the burden of disease.

Association of low general health status, measured prospectively by Euroqol EQ5D, with osteoporosis, independent of a history of prior fracture

OBJECTIVES

There have been no studies of generic health-related quality of life (HR-QOL) measured prospectively, in patients referred for bone mass measurement. The aim of this study was to examine the relationship between HR-QOL, measured before DXA scanning was undertaken, and bone mineral density (BMD). Comparison of HR-QOL with the age- and sex-matched general population was also made.

DESIGN

HR-QOL questionnaires were completed by patients who were being entered into a randomized, prospective, parallel group trial to assess the impact of direct access DXA scanning (DADS) versus referral to a hospital consultant, upon clinical decision making by general practitioners (GPs) (Dhillon et al., Osteoporos Int 14:326-333, 2003). HR-QOL questionnaires were completed prior to both randomization and DXA scanning.

PARTICIPANTS

325 patients from 18 representative general practices of a total of 77 in the city of Edinburgh. Patients had been referred by their GPs who had access to national guidelines on the identification of patients at high risk of osteoporosis.

OUTCOME MEASURES

Generic HR-QOL was measured using Euroqol (EQ5D). This provides a profile of self-reported problems in five dimensions (EQ5D(profile)), health utility (EQ5D(utility)), and a visual analogue global self-rated health assessment (EQ5D(vas)).

RESULTS

Odds ratios (ORs) for any self-reported problems on EQ5D(profile) were higher in patients with osteoporosis than those without, and compared with the general population. Age-adjusted mean (SD) EQ5D(utility )was significantly lower in patients with osteoporosis than in those without (0.65 [0.28] vs 0.76 [0.27]; p< 0.01), but the difference lessened with advancing age. Age-adjusted mean (SD) EQ5D(vas) was significantly reduced in patients with compared with no osteoporosis (68 [20] vs 76 [16]; p<0.01). There were no such differences in patients with a history of prior fracture compared with those without a history of prior fracture.

CONCLUSIONS

Female patients with osteoporosis have reduced generic HR-QOL compared with the age-matched female general population, irrespective of a history of prior fracture. The causal relationship between osteoporosis and HR-QOL, if any, is unclear. Further studies are needed to define this relationship and to determine whether treatment of osteoporosis has a beneficial effect on HR-QOL independent of fracture risk.

Home-based trunk-strengthening exercise for osteoporotic and osteopenic postmenopausal women without fracture--a pilot study

OBJECTIVES

To investigate whether a 12-week home-based programme of trunk-strengthening exercise could benefit spinal mobility, function and quality of life for osteoporotic and osteopenic postmenopausal women without fracture.

DESIGNS

Randomized controlled clinical trial.

SETTING

Department of Physical Therapy in National Taiwan University Hospital.

SUBJECTS

Twenty-eight postmenopausal women (mean age 60.3+/-9.3 years) diagnosed with osteoporosis or osteopenia without fracture history were recruited for this study. Subjects were randomly assigned into exercise or control groups, each consisting of 14 subjects.

INTERVENTIONS

The 12-week exercise programme included strengthening routines for the trunk extensor and flexor muscles. The subjects performed three sets of 10 repetitions for each of the exercises, with programmes carried out three times per day at home.

MAIN OUTCOME MEASUREMENTS

Muscular strength, spinal range of motion (ROM) and motion velocity, Oswestry Disability Questionnaire (ODQ) and quality of life (QOL) were measured before the start and after completion of the exercise programme.

RESULTS

Statistically significant improvements were demonstrated in spinal ROM and motion velocity in the sagittal and frontal planes for the exercise group (p<0.05). Further, the strength of the trunk flexors and extensors increased after exercise training (p<0.05). ODQ measure was significantly reduced in the exercise group (p<0.05), while the controls showed no significant change. Subjects in the exercise group showed better satisfaction in some domains of the Short-Form-36 Health Survey quality of life questionnaire (p<0.05).

CONCLUSIONS

This 12-week home-based trunk-strengthening exercise programme could improve trunk mobility and strength, and enhance QOL in osteoporotic and osteopenic postmenopausal women without vertebral fracture. Future study should recruit more cases or more severe subjects to verify the results.

A prospective clinical practice intervention to improve osteoporosis management following distal forearm fracture

Secondary prevention of osteoporosis after fracture is underutilized, despite cost-effective therapies. This clinical practice intervention aimed to improve osteoporosis care of the postfracture patient. Residents of Olmsted County, Minnesota, USA, > or = age 45 who sustained a moderate trauma distal forearm fracture were identified, and participants received educational materials, referral for bone densitometry and physician consultation to address osteoporosis in January 1999 through October 2000. Osteoporosis educational materials were provided to patients at the time of recruitment, and primary care physicians provided osteoporosis practice guidelines. Outcomes included: completion of bone densitometry, acceptance of interventions at the first postfracture primary care physician visit, and adherence to advice at 6 months. There were 105 patients identified (80% women), but only 58 agreed to participate (88% women). Women with lower T-scores (< -1.5) had an 89% initial treatment rate, and 67% were adherent to treatment at 6 months. All women with normal bone density (T-score above -1.5) were advised by their primary care physicians about antiresorptive treatment, and 100% adhered to these recommendations, even though they were not eligible for such treatment based on the National Osteoporosis Foundation (NOF) guidelines. None of the men accepted the treatments offered, despite T-scores that fell at or below the NOF treatment threshold. Bone densitometry and consultation improved osteoporosis interventions after index fracture from a 16% baseline rate in the population (1993-1997) to a 45% overall rate for the study population. In summary, while referral for bone densitometry and discussion by a physician about postfracture osteoporosis preventive treatments did increase treatment rate, the majority of patients at highest risk did not accept interventions. Further initiatives are needed to overcome both system and patient barriers.

Health-related quality of life and radiographic vertebral fracture

BACKGROUND

Vertebral fractures are associated with back pain and disability; however, relatively little is known about the impact of radiographic vertebral fractures on quality of life in population samples. The aim of this study was to determine the impact of a recent radiographic vertebral fracture on health-related quality of life (HRQoL).

METHODS

Men and women aged 50 years and over were recruited from population registers in 12 European centers. Subjects completed an interviewer-administered questionnaire and had lateral spine radiographs performed. Subjects in these centers were followed prospectively and had repeat spinal radiographs performed a mean of 3.8 years later. Prevalent deformities were defined using established morphometric criteria, and incident vertebral fractures by both morphometric criteria and qualitative assessment. For each incident fracture case, three controls matched for age, gender, and center were selected: one with a prevalent deformity (at baseline) and two without prevalent deformities. All subjects were interviewed or completed a postal questionnaire instrument which included Short Form 12 (SF-12), the EQ-5D (former EuroQol), and the quality of life questionnaire of the International Osteoporosis Foundation (QUALEFFO). The median time from the second spinal radiograph until the quality of life survey was 1.9 years. Comparison between cases and their matched controls was undertaken using the signed rank test.

RESULTS

73 subjects with incident vertebral fracture (cases), mean age 64.8 years (of whom 23 had a baseline deformity), and 196 controls, mean age 63.9 years (of whom 60 had a baseline deformity), were studied. There were strong correlations between the domain scores for each of the three instruments. There was no statistically significant difference in any of the domain scores between cases and those controls with a prevalent deformity. However, compared with the controls without a prevalent deformity the cases had significantly impaired quality of life as determined using the total QUALEFFO score (38.2 vs 33.7), the physical component score of the SF-12 (39.9 vs 43.7) and the health status score of the EQ-5D (62.3 vs 69.9). When the analysis was repeated after stratification of the cases by baseline deformity status (i.e., cases with and without a prevalent deformity at baseline), cases with a prevalent deformity had impaired quality of life compared with their matched controls, both with and without a prevalent deformity. In contrast there was no significant difference in quality of life among the cases without a prevalent deformity and either control group.

CONCLUSIONS

In this population-based study a recent vertebral fracture was associated with impairment in quality of life, though this was mainly among those who had sustained a previous vertebral deformity.

The Impact of Fragility Fracture on Health-Related Quality of Life

Both general and specific health status instruments can be utilised in evaluating health-related quality of life (HR-QOL) deficits resulting from osteoporotic fractures. Osteoporotic hip, vertebral and wrist fractures significantly decrease HR-QOL in most HR-QOL domains investigated. The presence of multiple vertebral fractures leads to larger decrements in HR-QOL. More research needs to be completed with these HR-QOL tools to better assess the true burden of osteoporotic fractures, particularly in the case of hip fractures, as the burden is surely being underestimated without recognition of HR-QOL. Only when the burden of fragility fractures is understood, inclusive of HR-QOL, will the value of proven antifracture prevention and treatment therapies be appreciated. Information collected by HR-QOL instruments may provide new insight as to how to improve quality of life for patients with fractures and how to properly allocate healthcare spending.
