RESUMO
In postmenopausal women with osteoporosis, up to 10 years of denosumab treatment significantly and continuously improved bone microarchitecture assessed by tissue thickness-adjusted trabecular bone score, independently of bone mineral density. Long-term denosumab treatment decreased the number of high fracture-risk patients and shifted more patients to lower fracture-risk categories. PURPOSE: To investigate the long-term effect of denosumab on bone microarchitecture assessed by tissue thickness-adjusted trabecular bone score (TBSTT) in post-hoc subgroup analysis of FREEDOM and open-label extension (OLE). METHODS: Postmenopausal women with lumbar spine (LS) or total hip BMD T-score <-2.5 and ≥-4.0 who completed the FREEDOM DXA substudy and continued in OLE were included. Patients received either denosumab 60 mg subcutaneously every 6 months for 3 years and same-dose open-label denosumab for 7 years (long-term denosumab; n=150) or placebo for 3 years and open-label denosumab for 7 years (crossover denosumab; n=129). BMD and TBSTT were assessed on LS DXA scans at FREEDOM baseline, month 1, and years 1-6, 8, and 10. RESULTS: In long-term denosumab group, continued increases from baseline to years 4, 5, 6, 8, and 10 in BMD (11.6%, 13.7%, 15.5%, 18.5%, and 22.4%) and TBSTT (3.2%, 2.9%, 4.1%, 3.6%, and 4.7%) were observed (all P < 0.0001). Long-term denosumab treatment decreased the proportion of patients at high fracture-risk (according to TBSTT and BMD T-score) from baseline up to year 10 (93.7 to 40.4%), resulting in increases in the proportions at medium-risk (6.3 to 53.9%) and low-risk (0 to 5.7%) (P < 0.0001). Similar responses were observed in crossover denosumab group. Changes in BMD and TBSTT were poorly correlated during denosumab treatment. CONCLUSION: In postmenopausal women with osteoporosis, up to 10 years of denosumab significantly and continuously improved bone microarchitecture assessed by TBSTT, independently of BMD, and shifted more patients to lower fracture-risk categories.

TBS algorithm has been updated to account for regional soft tissue noise. In postmenopausal women with osteoporosis, denosumab improved tissue thickness-adjusted TBS vs placebo independently of bone mineral density over 3 years, with the magnitude of changes from baseline or placebo numerically greater than body mass index-adjusted TBS. INTRODUCTION: To evaluate the effect of denosumab on bone microarchitecture assessed by trabecular bone score (TBS) in the FREEDOM study using the updated algorithm that accounts for regional soft tissue thickness (TBSTT) in dual-energy X-ray absorptiometry (DXA) images and to compare percent changes from baseline and placebo with classical body mass index (BMI)-adjusted TBS (TBSBMI). METHODS: Postmenopausal women with lumbar spine or total hip bone mineral density (BMD) T score < - 2.5 and ≥ - 4.0 received placebo or denosumab 60 mg subcutaneously every 6 months. TBSBMI and TBSTT were assessed on lumbar spine DXA scans at baseline and months 1, 12, 24, and 36 in a subset of 279 women (129 placebo, 150 denosumab) who completed the 3-year FREEDOM DXA substudy and rolled over to open-label extension study. RESULTS: Baseline characteristics were similar between groups. TBSTT in the denosumab group showed numerically greater changes from both baseline and placebo than TBSBMI at months 12, 24, and 36. Denosumab led to progressive increases in BMD (1.2, 5.6, 8.1, and 10.5%) and TBSTT (0.4, 2.3, 2.6, and 3.3%) from baseline to months 1, 12, 24, and 36, respectively. Both TBS changes were significant vs baseline and placebo from months 12 to 36 (p < 0.0001). As expected, BMD and TBSTT were poorly correlated both at baseline and for changes during treatment. CONCLUSION: In postmenopausal women with osteoporosis, denosumab significantly improved bone microstructure assessed by TBSTT over 3 years. TBSTT seemed more responsive to denosumab treatment than TBSBMI and was independent of BMD.

To evaluate whether treatment sequence affects romosozumab response, this analysis reviewed studies where romosozumab was administered before or following an antiresorptive (alendronate or denosumab). Initial treatment with romosozumab followed by an antiresorptive resulted in larger increases in bone mineral density of both hip and spine compared with the reverse sequence. INTRODUCTION: Teriparatide followed by an antiresorptive increases bone mineral density (BMD) more than using an antiresorptive first. To evaluate whether treatment sequence affects romosozumab response, we reviewed randomized clinical trials where romosozumab was administered before (ARCH, FRAME) or following (STRUCTURE, Phase 2 extension) an antiresorptive (alendronate or denosumab, respectively). METHODS: We evaluated BMD percentage change for total hip (TH) and lumbar spine (LS) and response rates (BMD gains ≥ 3% and ≥ 6%) at years 1 and 2 (except STRUCTURE with only 1-year data available). RESULTS: With 1-year romosozumab initial therapy in ARCH and FRAME, TH BMD increased 6.2% and 6.0%, and LS BMD increased 13.7% and 13.1%, respectively. When romosozumab was administered for 1 year after alendronate (STRUCTURE) or denosumab (Phase 2 extension), TH BMD increased 2.9% and 0.9%, respectively, and LS BMD increased 9.8% and 5.3%, respectively. Over 2 years, TH and LS BMD increased 7.1% and 15.2% with romosozumab/alendronate, 8.5% and 16.6% with romosozumab/denosumab, and 3.8% and 11.5% with denosumab/romosozumab, respectively. A greater proportion of patients achieved BMD gains ≥ 6% when romosozumab was used first, particularly for TH, versus the reverse sequence (69% after romosozumab/denosumab; 15% after denosumab/romosozumab). CONCLUSION: In this study, larger mean BMD increases and greater BMD responder rates were achieved when romosozumab was used before, versus after, an antiresorptive agent. Since BMD on treatment is a strong surrogate for bone strength and fracture risk, this analysis supports the thesis that initial treatment with romosozumab followed by an antiresorptive will result in greater efficacy versus the reverse sequence.

The study examined long-term direct and indirect economic burden of osteoporotic fractures among postmenopausal women. Healthcare costs among fracture patients were substantial in first year after fracture and remained higher than fracture-free controls for 5 years which highlight needs for early detection of high-risk patients and continued management for osteoporosis. INTRODUCTION: This study compared direct and indirect healthcare costs between postmenopausal women and demographically matched controls in the 5 years after incident non-traumatic fracture, and by fracture type in commercially insured and Medicare populations. METHODS: Two hundred twenty-six thousand one hundred ninety women (91,925 aged 50-64 years; 134,265 aged ≥ 65 years) with incident non-traumatic fracture (hip, vertebral, and non-hip non-vertebral (NHNV)) from 2008 to 2017 were identified. Patients with fracture were directly matched (1:1) to non-fracture controls based on demographic characteristics. Direct healthcare costs were assessed using general linear models, adjusting for baseline costs, comorbidities, osteoporosis diagnosis, and treatment. Indirect costs associated with work loss due to absenteeism and short-term disability (STD) were assessed among commercially insured patients. Costs were standardized to 2019 US dollars. RESULTS: Osteoporosis diagnosis and treatment rates prior to fracture were low. Patients with fracture incurred higher direct costs across 5-year post-index compared with non-fracture controls, regardless of fracture type or insurance. For commercially insured hip fracture patients, the mean adjusted incremental direct healthcare costs in years 1, 3, and 5 were $59,327, $6885, and $3241, respectively. Incremental costs were lower, but trends were similar for vertebral and NHNV fracture types and Medicare-insured patients. Commercially insured patients with fracture had higher unadjusted indirect costs due to absenteeism and STD in year 1 and higher adjusted indirect costs due to STD at year 1 (incremental cost $5848, $2748, and $2596 for hip, vertebral, and NHNV fracture). CONCLUSIONS: A considerable and sustained economic burden after a non-traumatic fracture underscores the need for early patient identification and continued management.

Although clinical trials have shown that denosumab significantly increases bone mineral density at key skeletal sites more than oral bisphosphonates, evidence is lacking from head-to-head randomized trials evaluating fracture outcomes. This retrospective cohort study uses administrative claims data from Medicare fee-for service beneficiaries to evaluate the comparative effectiveness of denosumab vs alendronate in reducing fracture risk among women with PMO in the US. Women with PMO ≥ 66 yr of age with no prior history of osteoporosis treatment, who initiated denosumab (n = 89 115) or alendronate (n = 389 536) from 2012 to 2018, were followed from treatment initiation until the first of a specific fracture outcome, treatment discontinuation or switch, end of study (December 31, 2019), or other censoring criteria. A doubly robust inverse-probability of treatment and censoring weighted function was used to estimate the risk ratio associated with the use of denosumab compared with alendronate for hip, nonvertebral (NV; includes hip, humerus, pelvis, radius/ulna, other femur), non-hip nonvertebral (NHNV), hospitalized vertebral (HV), and major osteoporotic (MOP; consisting of NV and HV) fractures. Overall, denosumab reduced the risk of MOP by 39%, hip by 36%, NV by 43%, NHNV by 50%, and HV fractures by 30% compared with alendronate. Denosumab reduced the risk of MOP fractures by 9% at year 1, 12% at year 2, 18% at year 3, and 31% at year 5. An increase in the magnitude of fracture risk reduction with increasing duration of exposure was also observed for other NV fracture outcomes. In this cohort of almost half-a-million treatment-naive women with PMO, we observed clinically significant reductions in the risk of MOP, hip, NV, NHNV, and HV fractures for patients on denosumab compared with alendronate. Patients who remained on denosumab for longer periods of time experienced greater reductions in fracture risk.
Osteoporosis-related fractures can have a significant impact on the health and quality of life of women with postmenopausal osteoporosis, as well as pose a significant burden to society. Although clinical trials have shown that denosumab is more effective at increasing bone mineral density compared with alendronate, there is a lack of evidence evaluating the fracture risk between these 2 commonly used osteoporosis therapies. In this study using Medicare claims data for almost 500 000 women with postmenopausal osteoporosis with no prior history of osteoporosis medication use, we compared the risk of fracturean important outcome to patients and health care providersbetween denosumab and alendronate. Advanced analytic methods were implemented to ensure the study results were valid and were not unduly influenced by biases common in observational studies. We observed clinically meaningful reductions (from 30% up to 50%) in the risk of hip, nonvertebral, non-hip nonvertebral, hospitalized vertebral, and major osteoporotic fractures for patients treated with denosumab compared with alendronate. Patients who remained on denosumab for longer periods of time experienced greater reductions in fracture risk than those who remained on alendronate.

OBJECTIVE: Describe patient characteristics, health care resource utilization, costs, and humanistic burden of women with Medicare insurance with incident fragility fracture who were admitted to post-acute-care (PAC). DESIGN: Retrospective cohort study using 100% Medicare Fee-for-Service (FFS) data. SETTING AND PARTICIPANTS: Community-dwelling female Medicare beneficiaries with incident fragility fracture January 1, 2017, to October 17, 2019, resulting in PAC admission to a skilled nursing facility (SNF), home-health care, inpatient-rehabilitation facility, or long-term acute-care hospital. METHODS: Patient demographic/clinical characteristics were measured during 1-year baseline. Resource utilization and costs were measured during baseline, PAC event, and PAC follow-up. Humanistic burden was measured among SNF patients with linked Minimum Data Set assessments. Multivariable regression examined predictors of PAC costs after discharge and changes in functional status during SNF stay. RESULTS: A total of 388,732 patients were included. Compared with baseline, hospitalization rates were 3.5, 2.4, 2.6, and 3.1 times higher and total costs 2.7, 2.0, 2.5, and 3.6 times higher for SNF, home-health, inpatient-rehabilitation, and long-term acute-care, respectively, following PAC discharge. Utilization of dual-energy X-ray absorptiometry (DXA) and osteoporosis medications remained low: 8.5% to 13.7% received DXA during baseline vs 5.2% to 15.6% following PAC; 10.2% to 12.0% received osteoporosis medication during baseline vs 11.4% to 22.3% following PAC. Dual eligibility for Medicaid (ie, low income) was associated with 12% higher costs; Black patients had 14% higher costs. Activities of daily living scores improved 3.5 points during SNF stay, but Black patients had 1.22-point lower improvement than White patients. Pain intensity scores showed small improvement (-0.8 points). CONCLUSIONS AND IMPLICATIONS: Women admitted to PAC with incident fracture had high humanistic burden with little improvement in pain and functional status and significantly higher economic burden after discharge compared with baseline. Disparities in outcomes related to social risk factors were observed, with consistently low utilization of DXA and osteoporosis medications even after fracture. Results indicate a need for improved early diagnosis and aggressive disease management to prevent and treat fragility fractures.

It is uncertain whether the risk of vertebral fracture (VF) and multiple vertebral fractures (MVFs; ≥2 VFs) after denosumab (DMAb) discontinuation is related to treatment duration. A prior analysis of Fracture Reduction Evaluation of Denosumab in Osteoporosis Every 6 Months (FREEDOM) and FREEDOM Extension trials did not find a relationship with DMAb duration and may have underreported MVF incidence because it included women who did not have radiographs. In this post hoc exploratory analysis, the crude incidence and annualized rates of VF and MVF were determined in patients with ≥7 months' follow-up and ≥1 spine radiograph after discontinuing placebo or DMAb. A multivariate analysis was performed to identify predictors of MVF. Clinical characteristics of patients with ≥4 VFs were explored. This analysis included women who discontinued after placebo (n = 327) or DMAb either from FREEDOM or FREEDOM Extension (n = 425). The DMAb discontinuation group was subsequently dichotomized by treatment duration: short-term (≤3 years; n = 262) and long-term (>3 years; n = 213) treatment. For any VF, exposure-adjusted annualized rates per 100 patient-years (95% confidence interval [CI]) were 9.4 (95% CI, 6.4-13.4) for placebo, 6.7 (95% CI, 4.2-10.1) for short-term DMAb, and 10.7 (95% CI, 7.4-15) for long-term DMAb. Annualized rates for MVF were 3.6 (95% CI, 1.9-6.3), 2.9 (95% CI, 1.4-5.4), and 7.5 (95% CI, 4.8-11.1), respectively. Annualized rates for ≥4 VFs were 0.59 (95% CI, 0.1-2.1), 0.57 (95% CI, 0.1-2.1), and 3.34 (95% CI, 1.7-6.0), respectively. In a multivariate regression model, DMAb duration was significantly associated with MVF risk (odds ratio 3.0; 95% CI, 1.4-6.5). Of 15 patients with ≥4 VFs, 13 had DMAb exposure (mean ± standard deviation [SD], 4.9 ± 2.2 years). The risk of MVF after DMAb discontinuation increases with increased duration of DMAb treatment. Patients transitioning off DMAb after 3 years may warrant more frequent administration of zoledronic acid or another bisphosphonate to maintain bone turnover and bone mineral density (BMD) and prevent MVF. © 2022 The Authors.

OBJECTIVE: To evaluate changes in bone turnover and bone mineral density (BMD) in patients with rheumatoid arthritis (RA) receiving glucocorticoids, after discontinuation of denosumab for 12 months. METHODS: We conducted a randomized, double-blind, placebo-controlled, phase II study of RA patients. Patients received placebo, denosumab 60 mg, or denosumab 180 mg every 6 months for 12 months and were followed up for an additional 12 months after discontinuation, during which no bone loss prevention therapy was instituted. Changes from baseline in serum C-terminal telopeptide of type I collagen (CTX), serum procollagen type I N-terminal propeptide (PINP), and lumbar spine and total hip BMD were evaluated. RESULTS: In this post hoc analysis of patients treated with glucocorticoids at study baseline (n = 82), levels of CTX and PINP decreased significantly from baseline in both denosumab groups. Following denosumab discontinuation, CTX returned to baseline and was not significantly different from the placebo group 6 and 12 months after discontinuation. Median percentage changes from baseline PINP in those treated with denosumab 60 mg were -0.16% and 15.3% at 6 and 12 months, respectively, after discontinuation (P = 0.062 and P = 0.017, versus placebo); corresponding changes with denosumab 180 mg were 9.0% and 75.8%, respectively (P = 0.018 and P = 0.002 versus placebo). Compared to placebo, lumbar spine and total hip BMD increased in patients receiving denosumab and returned to baseline 12 months after discontinuation. No osteoporotic fractures were reported during treatment or in the off-treatment period. CONCLUSION: In this analysis of short-term denosumab use in RA patients receiving glucocorticoids, denosumab discontinuation resulted in a gradual increase in bone turnover, which was associated with a return to baseline lumbar spine and total hip BMD.

Recent studies suggest that the RANK/RANKL system impacts muscle function and/or mass. In the pivotal placebo-controlled fracture trial of the RANKL inhibitor denosumab in women with postmenopausal osteoporosis, treatment was associated with a lower incidence of non-fracture-related falls (p = 0.02). This ad hoc exploratory analysis pooled data from five placebo-controlled trials of denosumab to determine consistency across trials, if any, of the reduction of fall incidence. The analysis included trials in women with postmenopausal osteoporosis and low bone mass, men with osteoporosis, women receiving adjuvant aromatase inhibitors for breast cancer, and men receiving androgen deprivation therapy for prostate cancer. The analysis was stratified by trial, and only included data from the placebo-controlled period of each trial. A time-to-event analysis of first fall and exposure-adjusted subject incidence rates of falls were analyzed. Falls were reported and captured as adverse events. The analysis comprised 10,036 individuals; 5030 received denosumab 60 mg subcutaneously once every 6 months for 12 to 36 months and 5006 received placebo. Kaplan-Meier estimates showed an occurrence of falls in 6.5% of subjects in the placebo group compared with 5.2% of subjects in the denosumab group (hazard ratio = 0.79; 95% confidence interval 0.66-0.93; p = 0.0061). Heterogeneity in study designs did not permit overall assessment of association with fracture outcomes. In conclusion, denosumab may reduce the risk of falls in addition to its established fracture risk reduction by reducing bone resorption and increasing bone mass. These observations require further exploration and confirmation in studies with muscle function or falls as the primary outcome. © 2020 The Authors.

The 3-year placebo-controlled FREEDOM (Fracture REduction Evaluation of Denosumab in Osteoporosis Every 6 Months) trial established the antifracture efficacy of denosumab in postmenopausal women with osteoporosis. The 7-year open-label extension demonstrated that denosumab treatment for up to 10 years was associated with low rates of adverse events and low fracture incidence. The extension lacked a long-term control group, thus limiting the ability to fully evaluate long-term efficacy. This analysis provides a quantitative estimate of the long-term antifracture efficacy of denosumab based on two approaches: comparison with FRAX®- (Fracture Risk Assessment Tool-) and virtual twin-estimated 10-year fracture rates. Subjects who were randomized to denosumab in the FREEDOM trial, continued into the Extension study, completed the 10-year visit, and missed ≤1 dose in the FREEDOM trial and ≤1 dose in the Extension (n = 1278) were included in the analysis. The 10-year observed cumulative incidence of major osteoporotic fracture (MOF) and hip fractures was compared with the 10-year fracture probability predicted at baseline by FRAX, a computer-based fracture risk algorithm, and with that estimated for a hypothetical cohort of 10-year placebo controls (virtual twins). The observed 10-year fracture incidence was lower than the 10-year probability predicted by FRAX for both MOF (10.75% [95% CI, 9.05 to 12.46] versus 15.63% [95% CI, 15.08 to 16.18], respectively), and hip fractures (1.17% [95% CI, 0.58 to 1.76] versus 5.62% [95% CI, 5.28 to 5.97], respectively). The observed fracture incidence was also lower than the fracture rate estimated in a hypothetical cohort of 10-year placebo controls for MOF (23.13% [95% CI, 17.76 to 28.87]; relative risk 0.49 [95% CI, 0.36 to 0.64]). These data support the long-term efficacy of denosumab in reducing MOF and hip fractures in postmenopausal women with osteoporosis. © 2020 The Authors.

RESUMO
BACKGROUND: Continuity of care, a concept that in its broadest terms describes patient and provider coordination across time and settings, has evidenced a positive correlation with patient satisfaction and hospital readmission rates. Home health care, where patients receive care from a variety of healthcare practitioners, is one area where these measures are being investigated to determine the effectiveness of continuity of care. OBJECTIVE: To examine and synthesize the best available evidence related to the effectiveness of continuity of care interventions and their impact on patient satisfaction and all-cause hospital readmissions rates in the adult patient who is receiving home care services. INCLUSION CRITERIA: Male and female aged 18 years or older receiving home care services, regardless of diagnosis, stage or severity of disease, co-morbidities, or previous treatment received.All types and models of interventions for continuity of care delivered by nurses to patients receiving home care services were considered for inclusion in the review.Patient satisfaction and hospital readmissions.In this review randomised controlled trials were considered for inclusion. In their absence, other research designs, such as non-randomised controlled trials, quasi-experimental studies, and before and after studies were considered for inclusion. SEARCH STRATEGY: Published and unpublished literature in the English language was sought from the inception of the databases through November 1, 2011.The databases searched included: Academic Search Premier, CINAHL ERIC, Health Reference Center Academic, MEDLINE via PubMed, ProQuest Nursing and Allied Health Source, ProQuest Health Management, Cochrane Central Register of Controlled Trials, EMBASE, Health Source Nursing Academic, PsycINFO and Bio-Med. A search of the grey literature and virtual hand searching of relevant journals was also performed. METHODOLOGICAL QUALITY: Two reviewers evaluated the included studies for methodological quality using standardised critical appraisal instruments from the Joanna Briggs Institute. DATA COLLECTION: Data were extracted using standardised data extraction instruments from the Joanna Briggs Institute. DATA SYNTHESIS: Statistical pooling via meta-analysis was not possible. The results are presented in narrative form. RESULTS: Two randomised controlled trails and two quasi-experimental studies were included in this review. In one randomised controlled trial, 66% of patients rated their overall satisfaction with care as very good or excellent as compared with 63% of those receiving usual care at 24 months (p=0.31). Another randomised controlled trial reported no statistically significant difference between groups (p value not reported). In one quasi-experimental study there was higher satisfaction rate amongst intervention patients with a mean difference of 16.88 (95%CI[16.32, 17.43] compared with 14.65 (95%CI[13.61, 15.68] in the control group (p=0.001).In one randomised controlled trial there was no statistically significant difference between intervention and control groups in hospital admission rates per 1000 at year two (700 vs. 740; p=0.66). Another randomised controlled trial showed no difference in readmissions at 90 days between groups (36% vs. 35%; no p value reported). In one quasi-experimental study, the mean number of hospital readmissions per patient was higher in the intervention group compared to the control group (0.75; 95% CI[ 0.47, 1.03] vs. 0.66; 95% CI[ 0.40, 0.91]; p=0.599), In another quasi-experimental study, a statistically significant higher number of intervention group patients in the intervention group were discharged and remained at home (34 or 82.9%), compared to the control group (20 or 51.3%) (p<0.05). CONCLUSIONS: Home care interventions that include nurses and advanced practice nurses with specialised training in the care of the population served as the direct provider along with collaboration with an interdisciplinary team in a high-risk patient populations contributed to reduced hospital readmission rates. The outcomes of the included studies suggest that consistently scheduled home care services promote patient satisfaction.This review concluded that the utilisation of an advanced practice nurse with specialised training in a specific disease process in collaboration with a multidisciplinary team can affect readmission rates and patient satisfaction.Further research is needed that captures a diverse patient population in terms of age and illness and the role that an advanced practice nurse can play.
