Are Nursing Home Residents With Dementia Appropriately Treated for Fracture Prevention?

Diagnostic Value of Hounsfield Units for Osteoporotic Thoracolumbar Vertebral Non-Compression Fractures in Elderly Patients with Low-Energy Injuries

Background

Thoracolumbar vertebral fractures are common pathological fractures caused by osteoporosis in the elderly. These fractures are challenging to detect. This study aimed to evaluate the diagnostic value of Hounsfield units for osteoporotic thoracolumbar vertebral non-compression fractures in elderly patients with low-energy fractures.

Methods

The retrospective case-control study included elderly patients diagnosed with osteoporotic thoracolumbar vertebral fractures and non-fractured patients who underwent computed tomography examinations for lumbar vertebra issues during July 2017 and June 2020.

Results

This study included 216 patients with fractures (38 males and 178 females; average age: 77.28±8.68 years) and 124 patients without fractures (21 males and 103 females; average age: 75.35±9.57 years). The difference in Hounsfield units of the target (intermediate) vertebral body significantly differed between the two groups (54.74 ± 21.84 vs 5.86 ± 5.14; p<0.001). The ratios of Hounsfield units were also significantly different between the two groups (1.38 ± 1.60 vs 0.13 ± 0.23; p<0.001). The cut-off value for the difference in Hounsfield units to detect osteoporotic spine fractures was 25.35, with high sensitivity (98.5%), specificity (99.9%), and the area under the curve (AUC) (0.999, 95% CI: 0.999-1). The cut-off value for the odds ratio of Hounsfield units was 0.260, with high sensitivity (99.1%), specificity (92.7%), and AUC (0.970, 95% CI: 0.949-0.992).

Conclusion

The difference between Hounsfield units and the odds ratio of Hounsfield units might help diagnose osteoporotic thoracolumbar vertebral non-compression fractures in elderly patients with low-energy fractures.

Osteoporosis management in Australian aged care facilities: a mixed method study

Osteoporosis is a common but sub-optimally managed disease amongst aged care residents. Pharmacists undertaking comprehensive medication reviews is one strategy to improve osteoporosis management. Analysis of pharmacist medication review recommendations has identified common clinical practice issues that can be addressed to optimise osteoporosis management for aged care residents.

PURPOSE

This study investigates the prevalence of osteoporosis medicine use amongst Australian aged care residents and explores drug-related problems (DRPs) identified during medication reviews and pharmacist recommendations to resolve them.

METHODS

Resident demographics, medications, diagnoses, osteoporosis related DRPs, and recommendations to resolve them were extracted from medication review reports. A mixed methods approach was taken to analysis, involving descriptive statistical analysis and content analysis.

RESULTS

Medication review reports relating to 980 residents were collected. Antiresorptive therapies were used by 21.7% of residents, of which 87.2% were prescribed denosumab. Osteoporosis related DRPs represented 14.0% of all DRPs identified by pharmacists. Vitamin D was involved in 55.4% of these DRPs, the remainder concerned antiresorptive therapies (23.4%), medications contributing to osteoporosis (16.3%), and calcium (4.9%). Frequent deviations in practice from aged care clinical guidelines and consensus recommendations concerning vitamin D and calcium were found. DRPs and accompanying recommendations relating to denosumab revealed inadequate monitoring and inadvertent therapy disruptions.

CONCLUSION

Pharmacist identified DRPs and recommendations revealed common aspects of clinical practice that can be addressed to improve osteoporosis management for aged care residents. A need to raise awareness of aged care-specific consensus recommendations concerning vitamin D and calcium is evident. Facility protocols and procedures must be developed and implemented to ensure safe and effective use of denosumab.

Deprescribing bisphosphonates for older adults with dementia: perspectives of caregivers

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.

Prescriber Perspectives and Experiences with Deprescribing Versus Continuing Bisphosphonates in Older Nursing Home Residents with Dementia

BACKGROUND

Few guidelines address fracture prevention medication use in nursing home (NH) residents with dementia.

OBJECTIVE

We sought to identify factors that influence prescriber decision-making for deprescribing of bisphosphonates for older NH residents with dementia.

METHODS

We conducted 12 semi-structured interviews with prescribers who care for older adults with dementia in NHs.

MAIN MEASURES

Interview prompts addressed experiences treating fractures, benefits, and harms of bisphosphonates, and experiences with deprescribing. Coding was guided by the social-ecological framework including patient-level (intrapersonal) and external (interpersonal, system, community, and policy) influences.

RESULTS

Most prescribers were physicians (83%); 75% were female and 75% were White. Most (75%) spent less than half of their clinical effort in NHs and half were in the first decade of practice. Among patient-level influences, prescribers uniformly agreed that a prior bisphosphonate treatment course of several years, emergence of adverse effects, and changing goals of care or limited life expectancy were compelling reasons to deprescribe. External influences were frequently discussed as barriers to deprescribing. At the interpersonal level, prescribers noted that family/informal caregivers are diverse in their involvement in decision-making, and frequently concerned about the adverse effects of bisphosphonates, but perceive deprescribing as "withdrawing care." At the health system level, prescribers felt that frequent transitions make it difficult to determine duration of prior treatment and to implement deprescribing. At the policy level, prescribers highlighted the lack of guidelines addressing residents with limited mobility and dementia or criteria for deprescribing, including uncertainty in the setting of prior fractures and lack of bone densitometry in NHs.

CONCLUSION

Systems-level barriers to evaluating bone densitometry and treatment history in NHs may impede person-centered decision-making for fracture prevention. Further research is needed to evaluate the residual benefits of bisphosphonates in medically complex residents with limited mobility and dementia to inform recommendations for deprescribing versus continued use.

Anabolic and Antiresorptive Osteoporosis Treatment: Trends, Costs, and Sequence in a Commercially Insured Population, 2003-2021

New anabolic medications (abaloparatide and romosozumab) were recently approved for osteoporosis, and data suggest that prescribing antiresorptive medications after a course of anabolic medications offers better outcomes. This study aimed to characterize prescription trends, demographics, geographical distributions, out-of-pocket costs, and treatment sequences for anabolic and antiresorptive osteoporosis medications. Using a commercial claims database (Clinformatics Data Mart), adult patients with osteoporosis from 2003 to 2021 were retrospectively reviewed and stratified based on osteoporosis medication class. Patient demographics and socioeconomic variables, provider types, and out-of-pocket costs were collected. Multivariable regression analyses were used to identify independent predictors of receiving osteoporosis treatment. A total of 2,988,826 patients with osteoporosis were identified; 616,635 (20.6%) received treatment. Patients who were female, Hispanic or Asian, in the Western US, had higher net worth, or had greater comorbidity burden were more likely to receive osteoporosis medications. Among patients who received medication, 31,112 (5.0%) received anabolic medication; these were more likely to be younger, White patients with higher education level, net worth, and greater comorbidity burden. Providers who prescribed the most anabolic medications were rheumatologists (18.5%), endocrinologists (16.8%), and general internists (15.3%). Osteoporosis medication prescriptions increased fourfold from 2003 to 2020, whereas anabolic medication prescriptions did not increase at this rate. Median out-of-pocket costs were $17 higher for anabolic than antiresorptive medications, though costs for anabolic medications decreased significantly from 2003 to 2020 (compound annual growth rate: -0.6%). A total of 8388 (1.4%) patients tried two or more osteoporosis medications, and 0.6% followed the optimal treatment sequence. Prescription of anabolic osteoporosis medications has not kept pace with overall osteoporosis treatment, and there are socioeconomic disparities in anabolic medication prescription, potentially driven by higher median out-of-pocket costs. Although prescribing antiresorptive medications after a course of anabolic medications offers better outcomes, this treatment sequence occurred in only 0.6% of the study cohort. © 2023 The Authors.

Nursing Home PRevention of Injury in DEmentia (NH PRIDE): A pilot study of a remote injury prevention service for NH residents

BACKGROUND

Medication optimization, including prescription of osteoporosis medications and deprescribing medications associated with falls, may reduce injurious falls. Our objective was to describe a remote, injury prevention service (NH PRIDE) designed to optimize medication use in nursing homes (NHs), and to describe its implementation outcomes in a pilot study.

METHODS

This was a non-randomized trial (pilot study) including NH staff and residents from five facilities. Long-stay residents at high-risk for injurious falls were identified using a validated risk calculator and staff referral. A remote team reviewed the electronic health record (EHR) and provided recommendations as Injury Prevention Plans (IPP). A research nurse served as a care coordinator focused on resident engagement and shared decision-making. Outcomes included implementation measures, as identified in the EHR, and surveys and interviews with staff.

RESULTS

Across five facilities, 274 residents were screened for eligibility, and 46 residents (16.8%) were enrolled. Most residents were female (73.9%) and had dementia (63.0%). An IPP was completed for 45 residents (97.8%). The nurse made a total of 93 deprescribing recommendations in 36 residents (80% of residents had one or more deprescribing recommendation; mean 2.2 recommendations/resident). Twenty of 45 residents (44.4%) had a recommendation for osteoporosis treatment. Among residents with recommendations, 21/36 (58.3%) had one or more deprescribing orders written and 6/20 (30.0%) had an osteoporosis medication prescribed. At 4 months, most medication changes persisted. Adverse side effects were rare. Staff members identified several areas for program refinement, including aligning recommendations with provider workflow and engaging consultant psychiatrists.

CONCLUSIONS

A remote injury prevention service is safe and feasible to enhance deprescribing and osteoporosis treatment in long-stay NH residents at risk for injury. Additional investigation is needed to determine if this model could reduce injurious falls when deployed across NH chains.

Treatment rates and healthcare costs of patients with fragility fracture by site of care: a real-world data analysis

In a characterization of treatment rates and healthcare costs among patients with an osteoporotic-related fragility fracture overall and by site of care, costs were high and treatment rates were low.

PURPOSE

Osteoporotic fractures can be debilitating, even fatal, among older adults. The cost of osteoporosis and related fractures is projected to increase to more than $25 billion by 2025. The objective of this analysis is to characterize disease-related treatment rates and healthcare costs of patients with an osteoporotic fragility fracture overall and by site of fracture diagnosis.

METHODS

In this retrospective analysis, individuals with fragility fractures were identified in the Merative MarketScan® Commercial and Medicare Databases among women 50 years of age or older and diagnosed with fragility fracture between 1/1/2013 and 6/30/2018 (earliest fracture diagnosis = index). Cohorts were categorized by clinical site of care where the diagnosis of fragility fracture was made and were continuously followed for 12 months prior to and following index. Sites of care were inpatient admission, outpatient office, outpatient hospital, emergency room hospital, and urgent care.

RESULTS

Of the 108,965 eligible patients with fragility fracture (mean age 68.8), most were diagnosed during an inpatient admission or outpatient office visit (42.7%, 31.9%). The mean annual healthcare costs among patients with fragility fracture were $44,311 (± $67,427) and were highest for those diagnosed in an inpatient setting ($71,561 ± $84,072). Compared with other sites of care at fracture diagnosis, patients diagnosed during an inpatient admission also had highest proportion of subsequent fractures (33.2%), osteoporosis diagnosis (27.7%), and osteoporosis therapy (17.2%) during follow-up.

CONCLUSION

The site of care for diagnosis of fragility fracture affects treatment rates and healthcare costs. Further studies are needed to determine how attitude or knowledge about osteoporosis treatment or healthcare experiences differ at various clinical sites of care in the medical management of osteoporosis.

National trends in osteoporosis medication use among Medicare beneficiaries with and without Alzheimer's disease/related dementias

BACKGROUND

Osteoporotic fractures  are a leading cause of disability and premature death in the elderly. Patients with Alzheimer's and related dementia (ADRD) have high rates of osteoporosis (OP) and substantial risk of osteoporotic fractures. Yet research is sparse on trends and predictors of OP medication use in ADRD.

METHODS

Medicare beneficiaries with OP aged ≥ 67 years have Medicare parts A/B/D without HMO from 2016 to 2018. Our outcome was receipt of OP medications in 2018. A multivariable logistic regression assessed association between ADRD and OP drug prescribing, adjusted for age, sex, race, region, Medicare entitlement, dual Medicaid eligibility, chronic conditions, number of provider visits/hospitalizations, and nursing home (NH) resident status. Age/ADRD and NH residency/ADRD interactions were tested.

RESULTS

Our sample consisted of 47,871 people with OP and ADRD and 201,840 with OP without ADRD. OP drug use was 38.6% in ADRD patients vs. 52.7% in non-ADRD. After adjustment for demographics, chronic conditions, and previous hospitalizations/physician visits, the OR for OP drug in ADRD vs. non-ADRD was 0.85 (95% CI: 0.83-0.87). NH residents had lower odds for OP medication (OR: 0.61, 95% CI: 0.58-0.64). There were significant interactions between ADRD and age, and between ADRD and NH residency. The OR for OP drug use associated with ADRD was 0.88 (95% CI: 0.86-0.90) among community-dwelling elders and 0.66 (95% CI: 0.64-0.69) among NH residents.

CONCLUSIONS

ADRD patients received OP drugs at a lower rate than their non-ADRD counterparts. More research is needed on when to prescribe or deprescribe OP drugs in the context of different ADRD severity, patient preferences, remaining life expectancy, and time-to-benefit from OP drugs.

Controversies in Osteoporosis Treatment of Nursing Home Residents

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.

Patterns of oral bisphosphonate deprescribing in older nursing home residents with dementia

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.

Improving shared decision-making for osteoporosis pharmacologic therapy in nursing homes: a qualitative analysis

Decisions on whether to use pharmacologic osteoporosis therapy in skilled nursing facility residents are complex and require shared decision-making. Residents, proxies, and staff desire individualized fracture risk estimates that consider advanced age, dementia, and mobility. They want options for reducing administration burden, monitoring instructions, and periodic reassessment of risk vs. benefit.

PURPOSE

Decisions about pharmacologic osteoporosis treatment in nursing home (NH) residents with advanced age and multimorbidity are complex and should occur using shared decision-making. Our objective was to identify processes and tools to improve shared decision-making about pharmacologic osteoporosis treatment in NHs.

METHODS

Qualitative analysis of data collected in three NHs from residents at high fracture risk, their proxies, nursing assistants, nurses, and one nurse practitioner (n = 28). Interviews explored participants' stories, attitudes, and experiences with oral osteoporosis medication management. Framework analysis was used to identify barriers to shared decision-making regarding osteoporosis treatment in this setting.

RESULTS

Participants wanted individualized fracture risk estimates that consider immobility, advanced age, and comorbid dementia. Residents and proxies expected nursing staff to be involved in the decision-making; nursing staff wished to be informed on the relative risks vs. benefits of medications and given monitoring instructions. Two important competing demands to address during the shared decision-making process were burdensome administration requirements and polypharmacy. Participants wanted to reassess pharmacologic treatment appropriateness over time as clinical status or goals of care change.

CONCLUSIONS

Shared decision-making using strategies and tools identified in this analysis may move osteoporosis pharmacologic treatment in NHs and for other older adults with multimorbidity from inappropriate inertia to appropriate prescribing or appropriate inaction.
