Abstract
Risk factors for nonadherence to osteoporosis medication have been well described for cohorts of women with osteoporosis, but little is known about predictors or mediators of nonadherence in men. We conducted a secondary analysis of a national cohort of male veterans to explore factors associated with nonadherence to osteoporosis medications. We included veterans with a prescription for an oral bisphosphonate or calcitonin between 2000 and 2010. We identified demographic, comorbid, and fracture-related risk factors by their International Classification of Diseases-9 (ICD-9) and Current Procedural Terminology (CPT) codes and used multivariable logistic regression to evaluate their association with adherence. Adherence was measured by medication possession ratio (MPR) over 5 years, starting at the time of their first prescription during the study period and censoring at death or end of study period. Of 135,306 men identified with at least one prescription for an osteoporosis medication during the study period, 90,406 (67%) were nonadherent (MPR < 0.80). The median duration of therapy was 3.2 years (interquartile range [IQR] = 1.7-5.0). In the fully adjusted model, the odds of adherence were lower in those aged <65 years (odds ratio [OR] = 0.87; 95% confidence interval [CI] 0.84-0.89), with no copay (OR = 0.78; 95% CI 0.76-0.80), dementia (OR = 0.87; 95% CI 0.83-0.91), anxiety/depression (OR = 0.92; 95% CI 0.90-0.95), tobacco use (OR = 0.91; 95% CI 0.89-0.94), alcohol abuse (OR = 0.91; 95% CI 0.89-0.94), rheumatoid arthritis (OR = 0.92; 95% CI 0.87-0.97), and on androgen deprivation therapy (OR = 0.89; 95% CI 0.83-0.95). The odds of adherence were higher in whites (OR = 1.14; 95% CI 1.11-1.17), with a prior screening colonoscopy (OR = 1.12; 95% CI 1.09-1.14), on alendronate versus other agents (OR = 1.61; 95% CI 1.55-1.67), with a dual-energy X-ray absorptiometry (DXA) (OR = 1.14; 95% CI 1.12-1.17), on glucocorticoids (OR = 1.08; 95% CI 1.02-1.14), and with recent fracture (OR = 1.07; 95% CI 1.04-1.10). In conclusion, adherence to oral bisphosphonates/calcitonin is poor, with particular subgroups at greatest risk. These findings may help tailor approaches for supporting adherence in men prescribed osteoporosis medications. © 2021 The Authors.

Hitz MF, Arup S, Holm JP, Soerensen AL, Gerds TA, Jensen JEB. Outcome of osteoporosis evaluation, treatment, and follow-up in patients referred to a specialized outpatient clinic compared to patients in care of general practitioners. Arch Osteoporos 2020; 15:97. [PMID: 32588150 DOI: 10.1007/s11657-020-00774-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2020] [Accepted: 06/19/2020] [Indexed: 02/03/2023]
Abstract
UNLABELLED In Denmark, osteoporosis treatment is either handled by general practitioners or at more resource demanding specialist clinics. We evaluated the treatment adherence and persistence in the two settings, which were overall similar. The type of medical support did, however, differ and was provided to two very different patient populations. PURPOSE The study aimed to investigate the effect of patient care by general practitioners (GPs) or specialists on treatment adherence among osteoporosis patients initiating treatment with oral bisphosphonates (OB). METHODS Dual-energy X-ray absorption (DXA)-scanning data from 2005 to 2013 were extracted. Treatment naïve patients with a T-score ≤ - 2.5 (spine or hip) were included. Information on medical treatment, comorbidities, and socio-economic status was extracted from Danish registries. Scanning results were evaluated by a specialist. Subsequent treatment initiation and follow-up was either handled by GPs or specialists: GP population (GPP) vs. specialist population (SP). Primary adherence was defined as treatment initiating within 12 months from diagnosis and secondary adherence as days with medicine possession rates (MPR) > 80%. RESULTS Of 11,201 DXA-scanned patients, 3685 met the inclusion criteria (GPP = 2177, SP = 1508). The GPP consisted of relatively more men, was older, had shorter education, lower income, and more comorbidities. There was no difference in baseline T-score or prior incidence of major osteoporotic fractures (MOFs). The GPP was primarily treated with OB and had better primary adherence (adjusted ORGPP/SP = 1.52 [1.31-1.75], p < 0.0001) than the SP that to a higher degree received another treatment. Secondary adherence was similar (adjusted ORGPP/SP: OR12 months = 1.02 [0.83-1.26]; OR24 months = 0.90 [0.73-1.10]; OR4 years = 0.88 [0.71-1.07]; OR5 years = 0.91 [0.74-1.13]. CONCLUSION Patients in care of specialists were most likely to receive a treatment other than OB. Primary adherence was highest in the GPP, whereas short- and long-term persistence was similar for up to 5 years whether treated by a specialist or a GP.

Abstract
The aim of this review was to identify factors that influence patients' adherence to anti-osteoporotic therapy. Factors identified that were associated with poorer medication adherence included polypharmacy, older age, and misconceptions about osteoporosis. Physicians need to be aware of these factors so as to optimize therapeutic outcomes for patients. INTRODUCTION To identify factors that influence patients' adherence to anti-osteoporotic therapy. METHODS A systematic review of literature was performed for articles published up till January 2018 using PubMed®, PsychINFO®, Embase®, and CINAHL®. Peer-reviewed articles which examined factors associated with anti-osteoporotic medication adherence were included. Classes of anti-osteoporotic therapy included bisphosphonates, parathyroid hormone-related analogue, denosumab, selective estrogen receptor modulators, estrogen/progestin therapy, calcitonin, and strontium ranelate. Meta-analyses, case reports/series, and other systematic reviews were excluded. Identified factors were classified using the World Health Organization's five dimensions of medication adherence (condition, patient, therapy, health-system, and socio-economic domains). RESULTS Of 2404 articles reviewed, 124 relevant articles were identified. The prevalence of medication adherence ranged from 12.9 to 95.4%. Twenty-four factors with 139 sub-factors were identified. Bisphosphonates were the most well-studied class of medication (n = 59, 48%). Condition-related factors that were associated with poorer medication adherence included polypharmacy, and history of falls was associated with higher medication adherence. Patient-related factors which were associated with poorer medication adherence included older age and misconceptions about osteoporosis while therapy-related factors included higher dosing frequency and medication side effects. Health system-based factors associated with poorer medication adherence included care under different medical specialties and lack of patient education. Socio-economic-related factors associated with poorer medication adherence included current smoker and lack of medical insurance coverage. CONCLUSION This review identified factors associated with poor medication adherence among osteoporotic patients. To optimize therapeutic outcomes for patients, clinicians need to be aware of the complexity of factors affecting medication adherence.

Adrenomedullin inhibits osteoclast differentiation through the suppression of receptor activator of nuclear factor-κB ligand-induced nuclear factor-κB activation in glucocorticoid-induced osteoporosis. Exp Ther Med 2017; 14:4009-4016. [PMID: 29067096 PMCID: PMC5647721 DOI: 10.3892/etm.2017.5025] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2016] [Accepted: 04/21/2017] [Indexed: 12/22/2022] Open
Abstract
The current study aimed to improve the understanding on the association between adrenomedullin and osteoporosis in mice with glucocorticoid-induced osteoporosis. Bone resorption and osteoporosis-associated indexes, including maximum load, stiffness, energy to failure, ultimate strength, elastic modulus, post-yield displacement and post-yield displacement, in mice with osteoporosis were analyzed in order to evaluate the effect of adrenomedullin. The receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclast differentiation was investigated subsequent to treatment with adrenomedullin in vitro. The results demonstrated that adrenomedullin significantly improved bone mass loss, density, bone strength and osteoporosis disease in the mice with glucocorticoid-induced osteoporosis. In addition, adrenomedullin markedly improved the osteoporosis-associated NFATc1, TRAP, OSCAR and c-Fos expression levels. Furthermore, the current findings indicated that RANKL-mediated osteoclast differentiation was suppressed in vitro and in vivo. Notably, the data revealed that adrenomedullin significantly improved the osteoporotic symptoms through inhibition of RANKL-induced NF-κB activation in glucocorticoid-induced osteoporosis. In conclusion, adrenomedullin serves an essential role in the progression of glucocorticoid-induced osteoporosis, regulating the bone mass loss, density and strength through the NF-κB signaling pathway.

BMC Musculoskelet Disord 2017; 18:152. [PMID: 28399834 PMCID: PMC5387221 DOI: 10.1186/s12891-017-1514-4] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2016] [Accepted: 04/04/2017] [Indexed: 02/08/2023] Open
Abstract
Background Poor adherence with oral bisphosphonates (BPs) can mitigate their therapeutic benefit for osteoporosis and is a significant clinical burden. Most previous studies regarding adherence with oral BPs have focused on postmenopausal osteoporosis, but little attention has been given to patients with rheumatoid arthritis (RA). Thus, we investigated compliance and persistence with oral BPs in the treatment of osteoporosis and analyzed risk factors for poor adherence in female patients with (RA) in real setting. Methods This is a retrospective longitudinal study including 396 female patients with RA in whom oral BPs were newly initiated from Aug 2004 to Aug 2014 at a university rheumatology center in South Korea. Compliance was quantified using the 1-year medication possession ratio (MPR), while persistence was defined as duration from the initiation to the end of BPs therapy without interruption exceeding 56 days. Seropositve RA was defined as having a positive test result for the presence of either rheumatoid factor or anti-cyclic citrullinated peptide antibody. Results Of 396 RA patients, 221 (55.8%) were prescribed risedronate 35 mg weekly; 17 (4.3%) received alendronate 70 mg weekly; and 158 (39.9%) received ibandronate 150 mg monthly. The 1-year MPR was 70.1% and the proportion of RA patients with the 1-year MPR ≥ 0.8 was 60.1%. A total of 274 (69.2%) patients discontinued oral BPs during the study period and persistence with BPs was 63.3% at 1 year, 50.7% at 2 years and 33.3% at 3 years. The most common cause of non-persistence was adverse events (47.5%), followed by poor health literacy (40.5%) and cost (12%). Both compliance and persistence with monthly oral BPs were significantly lower than those with weekly regimens (OR: 2.48, 95% CI: 1.59–3.89, P < 0.001 and HR: 2.19, 95% CI: 1.69–2.83, P < 0.001, respectively). Additionally, patients with seropositive RA showed better compliance and persistence with BPs compared with their seronegative counterparts. Conclusions Compliance and persistence with oral BPs in RA patients were suboptimal in real practice, thereby limiting the efficacy of osteoporosis treatment. Extending the dosing interval of BPs may improve medication adherence in RA patients.

Abstract
UNLABELLED Medication persistence and adherence are critical for osteoporosis outcomes. Using the Taiwan National Health Insurance Research Database, we found that persistence and adherence to teriparatide were low in Taiwanese patients with osteoporosis and that greater persistence and adherence were associated with a lower incidence of hip and other nonvertebral fractures. INTRODUCTION The purpose of this study was to determine the persistence and adherence to teriparatide treatment in Taiwanese patients with osteoporosis, and to examine the association between persistence and adherence to teriparatide with fracture risks. METHODS Medical and pharmacy claims for 4,692 patients with vertebral or hip fractures and teriparatide prescriptions between 2005 and 2008 were identified (Taiwan National Health Insurance Research Database). Persistence was the time from the start of treatment to the first 90-day gap between two teriparatide prescriptions. Adherence was the number of teriparatide pens (each pen is used over 1 month) prescribed over 24 months. Association of persistence and adherence to teriparatide with fracture incidence was assessed using adjusted Cox proportional hazards models. RESULTS The proportion of patients persisting with teriparatide for >6 months and >12 months was 44.6 and 24.9 %, respectively. Over 24 months, 53.6 % of patients were adherent for >6 months and 33.9 % were adherent for >12 months. Patients persisting for >12 months had a significantly lower incidence of hip (adjusted hazard ratio [HR], 0.61 [95 % confidence interval (CI), 0.40-0.93], P = 0.0229) and nonvertebral fracture (HR, 0.79 [95 % CI, 0.63-0.99], P = 0.0462) compared with those who persisted for ≤12 months. Patients adherent for >12 months had a lower incidence of hip (HR, 0.66 [95 % CI, 0.46-0.96], P = 0.0286) and nonvertebral fracture (HR, 0.81 [95 % CI, 0.66-0.99], P = 0.0377) compared with those adherent for ≤12 months. CONCLUSIONS Persistence and adherence to teriparatide over 24 months were low in Taiwanese patients with osteoporosis; greater adherence and persistence were associated with a lower incidence of nonvertebral fractures.

Abstract
UNLABELLED Approximately 15 % of older women on oral medications for osteoporosis could be considered for alternatives including parenteral therapies. Collection of data on socio-demographic/clinical variables is unlikely to be helpful in predicting low/non-adherence. Alternative approaches are needed to identify individuals at risk of low/non-adherence. INTRODUCTION This study aims to identify individual patient reasons for stopping medications for osteoporosis, and to investigate whether this can be predicted from knowledge about socio-demographic/clinical data, or whether alternative approaches need to be used. METHODS The Cohort for Skeletal Health in Bristol and Avon (COSHIBA) recruited 3200 older women from South West UK, of whom a proportion were on medications for osteoporosis at baseline. Information on self-reported adherence and reasons for low/non-adherence were collected at 6-monthly intervals over a 2-year period. Data was also collected on potential predictors of and impact of low/non-adherence. RESULTS Two hundred thirty-three of 3200 (7.3 %) women were on medications for osteoporosis at baseline. Mean length of time on treatment prior to enrolment was 46 months. Of those on osteoporosis medications, 94.9 % were on bisphosphonates; 8.5 % reported low adherence and 21.6 % stopped their medication completely over the 2-year follow-up period. Length of time on medication at baseline did not influence rates of low/non-adherence. Reasons for low/non-adherence to bisphosphonates included side effects (53.9 %), practical reasons such as forgetting to take them (18.0 %) and beliefs about medications (20.5 %). No convincing predictors of low/non-adherence were identified. CONCLUSIONS Approximately 15 % of older women on oral medications for osteoporosis could be considered for alternatives including parenteral therapies. This has important implications for healthcare provision. Collection of data on socio-demographic/clinical variables is unlikely to be helpful in predicting low/non-adherence. Alternative approaches are needed to identify individuals at risk of low/non-adherence to osteoporosis medications.

Abstract
PURPOSE Osteoporosis is a chronic disease and an important health and social burden due to its worldwide prevalence. Literature and clinical experience report incomplete adherence to the therapy. This retrospective observational study aimed at assessing the adherence to first-line antiosteoporosis drugs (AODs; reimbursed by the National Health System, according to the Italian Medicine Agency recommendation number 79), alendronate or risedronate, with or without calcium and/or vitamin D supplements, in a real, Italian clinical setting. PATIENTS AND METHODS Analyses were carried out on data present in the ARNO Observatory, a population-based patient-centric Italian database. From a population of 5,808,832 inhabitants with available data, a cohort of 3.3 million of patients aged ≥40 years was selected. New users of first-line AODs as monotherapy (accrual period, 2007-2009) were followed up over 3 years to assess adherence at 6, 12, and 36 months to AODs and to supplements and related determinants. RESULTS Approximately 40,000 new users were identified: mostly women, aged on average (standard deviation) 71±10 years. Alendronate was the most prescribed (38.2% of patients), followed by risedronate (34.9%) and alendronate with colecalciferol as a fixed-dose combination (25.8%). Adherence at the 6-month follow-up was 54%, and this constantly and significantly decreased after 1 year to 46%, and after 3 years to 33% (P<0.01). Adherence to the fixed-dose combination was higher than to plain alendronate throughout the follow-up period. Similarly, adherence to supplements constantly decreased with the duration of treatment. Women and patients aged >50 years were more likely to adhere to treatment regimen (P<0.001). The use of drugs for peptic ulcer and gastroesophageal reflux disease and of corticosteroids for systemic use were significantly associated with high adherence at different times. Polytherapy (>5 drugs), cardiovascular, and neurological therapies were significantly associated with low adherence throughout the follow-up period. CONCLUSION In a huge clinical practice sample, this study highlights suboptimal adherence to first-line AODs and to supplements and important determinants, such as concomitant therapies.

Abstract
UNLABELLED The objectives of this study were to estimate persistence with denosumab and put these results in context by conducting a review of persistence with oral bisphosphonates. Persistence with denosumab was found to be higher than with oral bisphosphonates. PURPOSE This study had two objectives: to analyse persistence in Swedish women initiating denosumab for treatment of postmenopausal osteoporosis (PMO) and to put these findings in context by conducting a literature review and meta-analysis of persistence data for oral bisphosphonates. METHODS The study used the Swedish Prescribed Drug Register and included women aged at least 50 years initiating denosumab between May 2010 and July 2012. One injection of denosumab was defined as 6-month persistence. Women were considered persistent for another 6 months if they filled their next prescription within 6 months + 56 days and survival analysis applied to the data. A literature search was conducted in PubMed to identify retrospective studies of persistence with oral bisphosphonates and pooled persistence estimates were calculated using a random-effects model. RESULTS The study identified 2,315 women who were incident denosumab users. Mean age was 74 years and 61% had been previously treated for PMO. At 12 and 24 months, persistence with denosumab was 83% (95% CI, 81-84%) and 62% (95% CI, 60-65%), respectively. The literature search identified 40 articles for inclusion in the meta-analysis. At 12 and 24 months, persistence with oral bisphosphonates ranged from 10% to 78% and from 16% to 46%, with pooled estimates of 45% and 30%, respectively. CONCLUSION These data from the Swedish Prescribed Drug Register and literature review suggest that persistence was higher with denosumab than with oral bisphosphonates.
