Little is known about caregivers' perspectives on deprescribing bisphosphonates for older adults with dementia. Caregivers agreed that fracture prevention was important for maintaining functional independence but acknowledged that changing goals of care may justify deprescribing. Conversations grounded in "what matters most" can align fracture prevention treatment with goals of care., Purpose: The long-term fracture prevention benefits of bisphosphonates may begin to be overshadowed by the potential burden of adverse effects and polypharmacy for older adults living with dementia as the disease progresses. We characterized factors that influence caregiver decision-making for continuing versus deprescribing bisphosphonates for persons living with dementia., Methods: We conducted 11 interviews with family or informal caregivers of older adults living with dementia in the community or in long-term care who had been treated with bisphosphonates. Interviews focused on experiences caring for someone who has experienced a fracture, perceived benefits and harms of bisphosphonates, and experiences with deprescribing. Analyses were conducted using a qualitative framework methodology guided by the Health Belief Model., Results: Most caregivers were male (n = 8), younger than 65 (n = 8) and were an adult child caregiver (n = 8). Three caregivers were Black and five were Latino/a. Attempts to maintain functional independence despite high likelihood of falls was frequently discussed as contributing to fracture risk, in this population. Many caregivers perceived fracture prevention treatment as important, while several noted that it may become less important near the end of life. Perceived benefits of fracture prevention treatment for persons with dementia included improved quality of life and maintaining independence. Although most indicated that bisphosphonates were well tolerated, gastrointestinal adverse effects, preference for fewer treatments, and dementia-related behaviors that interfere with medication administration may be reasons for deprescribing., Conclusion: Conversations grounded in caregiver experiences and "what matters most" may help optimize fracture prevention treatment for older adults with dementia., (© 2023.

Osteoporotic fractures are a common and serious health problem for older adults living in nursing homes (NHs). Risk of fracture increases with age and dementia status, yet gaps in evidence result in controversies around when to start and stop treatment for osteoporosis in NH residents, particularly those who have high fracture risk but have limited life expectancy. In this article, we discuss these areas of controversy. We provide an overview of current guidelines that explicitly address osteoporosis treatment strategies for NH residents, review the evidence for osteoporosis medications in NH residents, and use these sources to suggest practical recommendations for clinical practice and for research. Three published guidelines (from the United States, Canada, and Australia) and several studies provide the current basis for clinical decisions about osteoporosis treatment for NH residents. Practical approaches may include broad use of vitamin D and selective use of osteoporosis medication based on risks, benefits, and goals of care. Clinicians still lack strong evidence to guide treatment of NH residents with advanced dementia, multimorbidity, or severe mobility impairment. Future priorities for research include identifying optimal approaches to risk stratification and prevention strategies for NH residents and evaluating the risk-benefit profile of pharmacologic treatments for osteoporosis NH residents across key clinical strata. In the absence of such evidence, decisions for initiating and continuing treatment should reflect a patient-centered approach that incorporates life expectancy, goals of care, and the potential burden of treatment., (Copyright © 2022 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

Polyvinylchloride (PVC) based sealants commonly contain phthalate plasticizers that are emitted into the air over time. The low volatility classifies them as Semi-Volatile Organic Compounds (SVOCs). Empirical relationships are determined for estimation of the diffusion and solid/air partition coefficients for phthalates in PVC materials using data compiled from studies of phthalates in other PVC materials, such as vinyl flooring. The relationships are functions of vapor pressure of the compounds, which are determined from a Clausius-Clapeyron equation. A test chamber was constructed to continuously sample the air and measure the air concentration based on a Solid Phase MicroExtraction (SPME) method. The partition coefficient was tested with dioctyl terephthalate (DOTP) in a PVC-based sealant, in which the results fell within the reasonable error of the value predicted from the empirical relationship. The model is applied to outdoor and manufacturing scenarios to evaluate the effect of temperature and mass transfer coefficient., (Copyright © 2022. Published by Elsevier Ltd.)

In a national sample of Medicare nursing home residents with dementia treated with bisphosphonates, 20% had bisphosphonates deprescribed. Residents with clinical characteristics representing decreased likelihood for long-term benefit were more likely to have bisphosphonates deprescribed. Future studies are needed to evaluate outcomes of deprescribing bisphosphonates in this population., Introduction: To determine incidence of deprescribing bisphosphonates among nursing home (NH) residents with dementia and identify factors associated with deprescribing., Methods: 2015-2016 Medicare claims, Part D prescriptions, Minimum Data Set (MDS) 3.0, and Nursing Home Compare for non-skilled NH residents aged 65 + with dementia and prescriptions for oral bisphosphonates overlapping the first 14 days of the stay. Our primary definition for deprescribing was a 90-day gap in medication supply; we also explored the reliability of different deprescribing definitions (30-, 90-, 180-day gaps). We estimated associations of NH, provider, and resident characteristics with deprescribing bisphosphonates using competing risks regression models., Results: Most NH residents with dementia treated with bisphosphonates (n = 5312) were ≥ 80 years old (72%), white (81%), and female (90%); about half were dependent for transfers (50%) or mobility (45%). Using a 90-day gap in supply, the 180-day cumulative incidence of deprescribing bisphosphonates was 14.8%. This increased to 32.1% using a 30-day gap and decreased to 11.7% using a 180-day gap. Factors associated with increased likelihood for bisphosphonate deprescribing were age ≥ 90 years, newly admitted (vs. prevalent stay), dependent for mobility, swallowing difficulty, > 1 hospitalization in the prior year, CCRC facility, and nurse practitioner primary provider (vs. physician). Cancer and western geographic region were associated with reduced likelihood for deprescribing., Conclusion: In a national sample of NH residents with dementia, bisphosphonate deprescribing was uncommon, and associated with clinical characteristics signifying poor prognosis and decreased likelihood for long-term benefit. Future studies should evaluate clinical outcomes of deprescribing bisphosphonates in this population., (© 2021. International Osteoporosis Foundation and National Osteoporosis Foundation.)

Clinicians struggle with whether to prescribe osteoporosis medications for fracture prevention for older nursing home (NH) residents with dementia, given the lack of evidence in this population. To better understand real-world clinical practice, we conducted a retrospective cohort study examining patterns of fracture prevention medication use for older NH residents with dementia and high fracture risk. Data sources included 2015-16 Medicare claims, Part D prescriptions, and Minimum Data Set (MDS) assessments. Among NH residents aged 65+ with dementia and prior fracture or high fracture risk based on the MDS FRAiL (Fracture Risk Assessment in Long-term care), we assessed medications for fracture prevention using prescription data from 1 year prior through 90 days after the first MDS assessment. Multivariable logistic regression was used to evaluate factors associated with receiving treatment. Most of the sample (n = 72,639) was >80 years (78%), female (82%), and white (88%); 63% had moderate/severe dementia and 60% had an osteoporosis diagnosis. Only 11.6% received fracture prevention medications. In adjusted analyses, treated residents were more likely to be female, Hispanic or other non-black minority, <90 years old, and newly admitted to the NH. Other associated factors included osteoporosis diagnosis, walker or wheelchair use, bone disorders (eg, Paget disease), >5 medications, steroid or proton pump inhibitor use, and regions outside of the Northeast. Resident characteristics suggestive of comorbidity burden and worsening dementia were associated with reduced likelihood of treatment. Low use of fracture prevention medications for NH residents with dementia may reflect an attempt by prescribers reconcile medication use with changing goals of care, or inappropriate underuse in patients who still have high fracture risk. Additional research is needed to help clinicians better evaluate when to use these medications in this heterogeneous and vulnerable population., (Copyright © 2020 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

Objectives: To identify and describe geriatric scholarly concentration programs (GSCPs) among U.S. medical schools., Design: Survey and interview., Setting: Allopathic and osteopathic medical schools in the United States., Participants and Methods: We used a systematic internet search, forum postings, and word of mouth to identify all U.S. allopathic and osteopathic medical schools with existing GSCPs. GSCP directors completed an online survey. We conducted interviews with key faculty of two representative programs., Measurements: GSCP size, goals, duration of activity, requirements, funding sources, and student outcomes., Results: Nine GSCPs were identified, and eight responded to the survey. The number of current medical student participants ranged from 0 to 28, with a mean cohort size of 23. All programs included the following components: formal mentoring, clinical experiences in geriatric medicine beyond the standard medical school curriculum, and research. Half required students to complete an independent research project. GSCPs reported challenges, including low student interest, lack of availability of faculty mentors, and budget constraints; however, student satisfaction was high. Among three programs that reported on the residency matches of their graduates, half matched into a residency with a geriatric subspecialty training option., Conclusions: Among U.S. medical schools, there are few GSCPs. The GSCP model may help compensate for limited exposure to geriatric competencies in the standard medical school curriculum for a subset of interested students and may increase interest in geriatrics subspecialty training., (© 2020 The American Geriatrics Society.)
