Project description:BackgroundPain is common among individuals with Alzheimer's disease and related dementias (ADRD), and use of opioids has been increasing over the last decade. Yet, it is unclear to what extent opioids are appropriately prescribed for patients with ADRD and whether the appropriateness of opioid prescribing differs by ADRD status. The objective of this study is to compare the quality of opioid prescribing among patients with or without ADRD who have chronic noncancer pain.MethodsA nationally representative cohort study of Medicare beneficiaries aged 50 years or older who had chronic pain but who had no cancer, hospice, or palliative care from 2011 to 2015. Four indicators of potentially inappropriate opioid prescribing were measured in patients residing in communities (75,258 patients with and 435,870 patients without ADRD); five indicators were assessed in patients in nursing homes (NHs) (37,117 patients with and 5128 patients without ADRD). Each indicator was calculated as the proportion of eligible patients with inappropriate opioid prescribing in the year after a chronic pain diagnosis. Differences in proportions between ADRD and non-ADRD groups were estimated using a generalized linear model adjusting for covariates through inverse probability weighting.ResultsPatients with ADRD versus those without had higher concurrent use of opioids and central nervous system-active drugs (community 44.1% vs 33.3%; NH 58.8% vs 54.1%, both P < 0.001) and no opioids or scheduled pain medications for moderate or severe pain (NH 60.1% vs 52.5%, P < 0.001). The ADRD versus non-ADRD group had higher use of long-term opioids for treating neuropathic pain in communities (21.7% vs 19.5%, P = 0.003) but lower use in NHs (26.9% vs 36.0%, P < 0.001). Use of strong or high-dose opioids when naive to opioids (community 1.5% vs 2.8%; NH 2.5% vs 3.5%) and use of contraindicated opioids (community 0.08% vs 0.12%; NH 0.05% vs 0.21%) were rare for either group.ConclusionPotential inappropriate opioid prescribing in 2 areas of pain care was more common among patients with ADRD than among patients without ADRD in community or NH settings. Further studies aimed at understanding the factors and effects associated with opioid prescribing patterns that deviate from guidelines are warranted.

Project description:ObjectiveTo validate the Caregiver-Perceived Burden Questionnaire (CPBQ) and report its psychometric properties.MethodsThe CPBQ was administered to caregivers of patients with moderate-to-severe AD in a double-blind randomized trial comparing extended-release memantine to placebo (n = 676). Measurement properties were analyzed using factor analysis, classical test theory, and Rasch analysis.ResultsTwo subscales were identified: the Caregivers' Assessment of the Patient (CAP) and the Caregivers' Assessment of Themselves (CAT). The reliability was .89 (CAP) and .83 (CAT). The CAP scores were significantly correlated (r > .3) with scores from the Severe Impairment Battery (SIB) and the Neuropsychiatric Inventory (NPI). The CAT scores were significantly correlated with NPI scores. The CAT discriminated among patients by clinician-rated severity and significantly differentiated between responders and nonresponders.ConclusionThe CPBQ appears to be a reliable, valid, and responsive measure that enables linking caregiver's perceptions about burden and patient function in patients with moderate-to-severe AD.

Project description:ImportanceIndividuals with Alzheimer disease and related dementias (ADRD) frequently require skilled nursing facility (SNF) care following hospitalization. Despite lower SNF incentives to care for the ADRD population, knowledge on how the quality of SNF care differs for those with vs without ADRD is limited.ObjectiveTo examine whether persons with ADRD are systematically admitted to lower-quality SNFs.Design, setting, and participantsCross-sectional analysis of Medicare beneficiaries hospitalized between January 1, 2017, and December 31, 2019, was conducted. Data analysis was performed from January 15 to May 30, 2022. Participants were discharged to a Medicare-certified SNF from a general acute hospital. Patients younger than 65 years, enrolled in Medicare Advantage, and with prior SNF or long-term nursing home use within 1 year of hospitalization were excluded.ExposuresThe quality level of all SNFs available at the patient's discharge, measured using publicly reported 5-star staffing ratings. The 5-star ratings were grouped into 3 levels (1-2 stars [reference category, low-quality], 3 stars [average-quality], and 4-5 stars [high-quality]).Main outcomes and measuresThe outcome was the SNF a patient entered among the possible SNF destinations available at discharge. Differences in the association between SNF quality and SNF entry for patients with and without ADRD were assessed using a conditional logit model, which simultaneously controls for differences in discharging hospital, residential neighborhood, and the other characteristics (eg, postacute care specialization) of all SNFs available at discharge.ResultsThe sample included 2 619 464 patients (mean [SD] age, 81.3 [8.6] years; 61% women; 87% were White; 8% were Black; 22% with ADRD). The probability of discharge to higher quality SNFs was lower for patients with ADRD. If the star rating of an SNF was high instead of low, the log-odds of being discharged to it increased by 0.31 for patients with ADRD and by 0.47 for those without ADRD (difference, -0.16; P < .001). The weaker association between quality and entry for patients with ADRD indicates that they are less likely to be discharged to high-quality SNFs.Conclusions and relevanceThe findings of this study suggest that patients with ADRD are more likely to be discharged to lower-quality SNFs. Targeted reforms, such as ADRD-specific compensation adjustments, may be needed to improve access to better SNFs for patients with ADRD.

Project description:BackgroundDelirium is a distressing neurocognitive disorder recently linked to sleep disturbances. However, the longitudinal relationship between sleep and delirium remains unclear. This study assessed the associations of poor sleep burden, and its trajectory, with delirium risk during hospitalization.MethodsAbout 321 818 participants from the UK Biobank (mean age 58 ± 8 years [SD]; range 37-74 years) reported (2006-2010) sleep traits (sleep duration, excessive daytime sleepiness, insomnia-type complaints, napping, and chronotype-a closely related circadian measure for sleep timing), aggregated into a sleep burden score (0-9). New-onset delirium (n = 4 775) was obtained from hospitalization records during a 12-year median follow-up. About 42 291 (mean age 64 ± 8 years; range 44-83 years) had repeat sleep assessment on average 8 years after their first.ResultsIn the baseline cohort, Cox proportional hazards models showed that moderate (aggregate scores = 4-5) and severe (scores = 6-9) poor sleep burden groups were 18% (hazard ratio = 1.18 [95% confidence interval: 1.08-1.28], p < .001) and 57% (1.57 [1.38-1.80], p < .001), more likely to develop delirium, respectively. The latter risk magnitude is equivalent to 2 additional cardiovascular risks. These findings appeared robust when restricted to postoperative delirium and after exclusion of underlying dementia. Higher sleep burden was also associated with delirium in the follow-up cohort. Worsening sleep burden (score increase ≥2 vs no change) further increased the risk for delirium (1.79 [1.23-2.62], p = .002) independent of their baseline sleep score and time lag. The risk was highest in those younger than 65 years at baseline (p for interaction <.001).ConclusionPoor sleep burden and worsening trajectory were associated with increased risk for delirium; promotion of sleep health may be important for those at higher risk.

Project description:ImportanceLow early-life cognitive ability is a potential early marker of dementia risk in later life. Previous studies use only global measures of general intelligence and/or study this relationship in gender-specific samples. The contribution of early-life performance on specific cognitive abilities, such as language, reasoning, and visualization aptitudes, to indicating future dementia risk is unknown.ObjectivesTo investigate the association between adolescent cognitive ability and Medicare-recorded Alzheimer disease and related disorders (ADRD) using both general and specific measures of cognitive ability and to explore these associations separately in men and women.Design, setting, and participantsPopulation-based cohort study from the Project Talent-Medicare linked data set, a linkage of adolescent sociobehavioral data collected from high school students in 1960 to participants' 2012 to 2013 Medicare Claims and expenditures data. The association between adolescent cognitive ability and risk of ADRD in later life was assessed in a diverse sample of 43 014 men and 42 749 women aged 66 to 73 years using a series of logistic regressions stratified by sex, accounting for demographic characteristics, adolescent socioeconomic status, and regional effects. Data analysis was conducted from November 2017 to March 2018.Main outcomes and measuresPresence of Medicare-reported ADRD.ResultsOverall, 1239 men (2.9%) and 1416 women (3.3%) developed ADRD. Lower mechanical reasoning was associated with increased odds of ADRD in men (odds ratio, 1.17; 95% CI, 1.05-1.29), and lower memory for words in adolescence was associated with increased odds of ADRD in women (odds ratio, 1.16; 95% CI, 1.05-1.28). Lower performance on several other language, reasoning, visualization, and mathematic aptitudes in adolescence showed prominent, but weaker, associations with odds of ADRD.Conclusions and relevanceThis work contributes to the understanding of early-life origins of ADRD risk. The results suggest specific measures of cognitive ability may contribute to very early identification of at-risk subgroups who may benefit from prevention or intervention efforts.

Project description:ObjectiveInformal caregivers are crucial to maintaining older adults' health, but few studies examine how caregiving receipt is associated with older person longevity. In a nationally representative sample, we prospectively explore whether and how having an informal caregiver is associated with older adult overall mortality, and how caregivers' burden and benefits perceptions relate to care recipient mortality.MethodsWe match six National Health and Aging Trends Study waves (2011-2016) with 2011 National Study of Caregiving data, conducting survival analysis on 7,369 older adults and 1,327 older adult-informal caregiver dyads.ResultsHaving an informal caregiver is associated with 36% (p < .001) higher mortality risk over 6-year follow-up, adjusting for demographic, economic, and health factors. Older adults whose caregivers perceive only burden have 38% higher (p < .05) mortality risk than those with caregivers reporting neither burden nor benefits. This risk is reduced from 38% higher to 5% higher (p < .001) for older adults with caregivers reporting benefits alongside burden, compared to those with caregivers reporting neither perception.DiscussionHaving a caregiver may signal impending decline beyond known mortality factors. However, interventions to increase caregivers' benefit perceptions and reduce their burden may decrease mortality risk for older adults with declining health and functional ability.

Project description:The association between caregiver burden and the physical frailty of older adults has been the object of previous studies. The contribution of patients' dispositional optimism on caregiver burden is a poorly investigated topic. The present study aimed at investigating whether older adults' multidimensional frailty and optimism might contribute to the burden of their family caregivers. The Caregiver Burden Inventory was used to measure the care-related burden of caregivers. The multidimensional frailty status of each patient was evaluated by calculating a frailty index, and the revised Life Orientation Test was used to evaluate patients' dispositional optimism. The study involved eighty family caregivers (mean age 64.28 ± 8.6) and eighty older patients (mean age 80.45 ± 7.13). Our results showed that higher frailty status and lower levels of optimism among patients were significantly associated with higher levels of overall burden and higher burden related to the restriction of personal time among caregivers. Patients' frailty was additionally associated with caregivers' greater feelings of failure, physical stress, role conflicts, and embarrassment. Understanding the close connection between patient-related factors and the burden of caregivers appears to be an actual challenge with significant clinical, social, and public health implications.

Project description:INTRODUCTION:Caring for a person with Parkinson's disease (PD) is associated with an increased risk of psychiatric morbidity and persistent distress. The objective of this study was to describe the burden and the related factors of caregivers of advanced PD (APD) patients either treated with continuous dopaminergic delivery systems or standard therapy. METHODS:This cross-sectional, epidemiologic study conducted in 13 Italian sites enrolled PD patients treated with continuous dopaminergic delivering systems [either levodopa/carbidopa intestinal gel (LCIG) infusion or continuous subcutaneous apomorphine infusion (CSAI)] or continuation of standard of care (SOC) with a caregiver. Patient quality of life (QoL) and caregiver burden were assessed using the Parkinson's Disease Questionnaire (PDQ-8) and Zarit Burden Inventory (ZBI), respectively. RESULTS:126 patients (mean age 69.3?±?8 years) and their caregivers (mean age 57.9?±?12.9) were enrolled. Most caregivers were spouses. Fifty-three patients were treated with LCIG, 19 with CSAI, and 54 with SOC. Mean ZBI scores were 29.6?±?14.4 for LCIG, 35.8?±?20.2 for CSAI, and 31.4?±?16.0 for SOC. Caregivers of LCIG, CSAI, and SOC patients showed no burden or mild/moderate burden in 74, 53, and 63% of the cases, respectively. Mean PDQ-8 scores were 11.25?±?5.67, 11.26?±?5.55, and 14.22?±?6.51 in LCIG, CSAI, and SOC patients. Neurologists considered patients "very much or much improved" in 89, 58, and 13% of the LCIG, CSAI, and SOC groups using the Clinical Global Impression-Global Improvement Scale. Predictors significantly associated with caregiver burden were patients and caregivers' judgment of QoL and caregivers' need to change work. CONCLUSIONS:Caregiver burden showed a tendency to be lower when patients are treated with LCIG than with CSAI or SOC.

Project description:ObjectiveTo investigate the vascular contribution to longitudinal changes in Alzheimer disease (AD) biomarkers.MethodsThe Alzheimer's Disease Neuroimaging Initiative is a clinic based, longitudinal study with CSF, PET, and MRI biomarkers repeatedly measured in participants with normal cognition (NC), mild cognitive impairment (MCI), and mild AD. Participants with severe cerebrovascular risks were excluded. Cardiovascular risk scores and MRI white matter hyperintensities (WMHs) were treated as surrogate markers for vascular burden. Generalized estimating equations were applied, and both vascular burden and its interaction with time (vascular burden × time) or time-varying WMHs were entered into regression models to assess whether biomarker rates of change were modified by vascular burden.ResultsCardiovascular risk profiles were not predictive of progression in CSF β₄₂-amyloid, [¹⁸F]fluorodeoxyglucose (FDG) PET uptake, and MRI hippocampal atrophy. Greater baseline cardiovascular risks or WMHs were generally associated with cognitive impairment, particularly poor executive function. WMHs increased over time with a faster rate in MCI and AD than in NC. Increased time-varying WMH was associated with faster decline in executive function and lower FDG uptake in NC. Otherwise, WMH was not associated with CSF and MRI biomarkers in the 3 groups. These findings remained unchanged after accounting for APOE4.ConclusionIncreased WMHs are associated with aging, decreased glucose metabolism, and decline in executive function but do not affect AD-specific pathologic progression, suggesting that the vascular contribution to dementia is probably additive although not necessarily independent of the amyloid pathway.

Project description:Background/objectivesAs home becomes the most common place of death in the United States, information about caregiver support and place of death is critical to improve patient and caregiver experiences at end of life. We seek to examine (1) the association between family care availability and place of death; and (2) caregiving intensity associated with place of death.Design2017 National Health and Aging Trends Study and National Study of Caregiving; nationally representative cross-sectional study of deceased older adults and last-month-of-life (LML) caregivers.SettingUnited States; all places of deaths.ParticipantsThree-hundred and seventy-five decedents and 267 LML caregivers.MeasurementsPlace of death (home, hospital, and nursing or hospice facility), family care availability (spouse/partner, household size, number of daughters and sons), caregiving intensity (hours of help provided at LML and a binary indicator for high care-related emotional difficulty).Results38.9% of older adults died at home, followed by hospital (33.1%), and nursing or hospice facility (28.0%). In an adjusted multinomial logistic regression, decedents with larger household size (odds ratio [OR]: 0.441; 95% confidence interval [CI]: 0.269-0.724) and more daughters (OR: 0.743 [95% CI: 0.575-0.958]) had lower odds of dying in nursing or hospice facility relative to dying at home. For older adults who died at home, caregivers provided 209.8 h of help at LML. In contrast, when death occurred in nursing or hospice facility, caregivers provided 91.6 fewer hours of help, adjusted for decedent and caregiver characteristics. Dying in hospital was associated with higher odds of caregiver emotional difficulty relative to home deaths (OR: 4.093 [95% CI: 1.623-10.323]).ConclusionsHousehold size and number of daughters are important determinants of place of death. Despite dying at home being associated with more hours of direct caregiving; caregiver emotional strain was experienced as higher for hospital deaths. Better support services for end-of-life caregivers might improve patient and caregiver experiences for home and hospital deaths.
