Before Hospice: Symptom Burden, Dementia, and Social Participation in the Last Year of Life

Symptomatic and Preventive Medication Use before and after Alzheimer's Disease Diagnosis: A 10-Year Matched Cohort Study

OBJECTIVE

To investigate longitudinal changes in symptomatic and preventive medication use among community-dwelling people with and without Alzheimer's disease (AD) 5 years pre- and post-AD diagnosis.

DESIGN

Retrospective matched cohort study.

SETTINGS AND PARTICIPANTS

The sample comprised 58,496 people with a geriatrician/neurologist-verified AD diagnosis matched 1:1 for age, sex, and region to people without AD in Finland.

METHODS

Medication dispensing data were obtained from the Finnish Prescription Register. Prevalence of symptomatic and preventive medication use was evaluated every 6 months from 5 years pre- to post-AD diagnosis. Longitudinal changes in medication use between people with and without AD were compared using ordinal logistic regression.

RESULTS

During the 5 years pre- and post-diagnosis, there were differences in symptomatic (P < .001) and preventive (P = .006) medication use between people with and without AD. Over the 5 years pre-diagnosis, prevalence of symptomatic and preventive medications increased in both people with and without AD. During the 1 year pre-diagnosis, people with AD had a higher increase in use of ≥3 symptomatic medications (+4.4% vs +2.2%) and ≥3 preventive medications (+6.4% vs +2.9%) compared to people without AD. Over the 5 years post-diagnosis, symptomatic medication use plateaued in both people with and without AD. Meanwhile, people using ≥3 preventive medications decreased (-6.0%) in those with AD, but increased (+6.1%) in those without AD. During the follow-up period, people with AD had a larger absolute percentage increase in prevalence of antipsychotics (+22.7% vs +1.8%) and antidepressants (+19.1% vs +5.0%) than people without AD. During the same period, paracetamol and calcium supplement use increased by 31.1% and 20.4%, respectively, among people with AD. The largest absolute percentage decrease in prevalence of preventive medications over the 5 years post-diagnosis were beta-blockers (-9.8%) and statins (-7.0%) in people with AD.

CONCLUSIONS AND IMPLICATIONS

At the point of and following diagnosis, there were population-level changes in medication use among people with AD. Medication assessments during this period appear to coincide with discontinuation of preventive medications whereas minimal changes were observed in symptomatic medication use.

Symptomatic and preventive medication use according to age and frailty in Australian and Japanese nursing homes

OBJECTIVE

To investigate symptomatic and preventive medication use according to age and frailty in Australian and Japanese nursing homes (NHs).

METHODS

Secondary cross-sectional analyses of two prospective cohort studies involving 12 Australian NHs and four Japanese NHs. Frailty was measured using the FRAIL-NH scale (non-frail 0-2; frail 3-6; most-frail 7-14). Regular medications were classified as symptomatic or preventive based on published lists and expert consensus. Descriptive statistics were used to compare the prevalence and ratio of symptomatic to preventive medications.

RESULTS

Overall, 550 Australian residents (87.7 ± 7.3 years; 73.3% females) and 333 Japanese residents (86.5 ± 7.0 years; 73.3% females) were included. Australian residents used a higher mean number of medications than Japanese residents (9.8 ± 4.0 vs 7.7 ± 3.7, p < 0.0001). Australian residents used more preventive than symptomatic medications (5.5 ± 2.5 vs 4.3 ± 2.6, p < 0.0001), while Japanese residents used more symptomatic than preventive medications (4.7 ± 2.6 vs 3.0 ± 2.2, p < 0.0001). In Australia, symptomatic medications were more prevalent with increasing frailty (non-frail 3.4 ± 2.6; frail 4.0 ± 2.6; most-frail 4.8 ± 2.6, p < 0.0001) but less prevalent with age (< 80 years 5.0 ± 2.9; 80-89 years 4.4 ± 2.6; ≥ 90 years 3.9 ± 2.5, p = 0.0042); while preventive medications remained similar across age and frailty groups. In Japan, there was no significant difference in the mean number of symptomatic and preventive medications irrespective of age and frailty.

CONCLUSIONS

The ratio of symptomatic to preventive medications was higher with increasing frailty but lower with age in Australia; whereas in Japan, the ratio remained consistent across age and frailty groups. Preventive medications remained prevalent in most-frail residents in both cohorts, albeit at lower levels in Japan.

Medication misuse and overuse in community-dwelling persons with dementia

BACKGROUND

Persons with dementia (PWD) have high rates of polypharmacy. While previous studies have examined specific types of problematic medication use in PWD, we sought to characterize a broad spectrum of medication misuse and overuse among community-dwelling PWD.

METHODS

We included community-dwelling adults aged ≥66 in the Health and Retirement Study from 2008 to 2018 linked to Medicare and classified as having dementia using a validated algorithm. Medication usage was ascertained over the 1-year prior to an HRS interview date. Potentially problematic medications were identified by: (1) medication overuse including over-aggressive treatment of diabetes/hypertension (e.g., insulin/sulfonylurea with hemoglobin A1c < 7.5%) and medications inappropriate near end of life based on STOPPFrail and (2) medication misuse including medications that negatively affect cognition and medications from 2019 Beers and STOPP Version 2 criteria. To contextualize, we compared medication use to people without dementia through a propensity-matched cohort by age, sex, comorbidities, and interview year. We applied survey weights to make our results nationally representative.

RESULTS

Among 1441 PWD, median age was 84 (interquartile range = 78-89), 67% female, and 14% Black. Overall, 73% of PWD were prescribed ≥1 potentially problematic medication with a mean of 2.09 per individual in the prior year. This was notable across several domains, including 41% prescribed ≥1 medication that negatively affects cognition. Frequently problematic medications included proton pump inhibitors (PPIs), non-steroidal anti-inflammatory drugs (NSAIDs), opioids, antihypertensives, and antidiabetic agents. Problematic medication use was higher among PWD compared to those without dementia with 73% versus 67% prescribed ≥1 problematic medication (p = 0.002) and mean of 2.09 versus 1.62 (p < 0.001), respectively.

CONCLUSION

Community-dwelling PWD frequently receive problematic medications across multiple domains and at higher frequencies compared to those without dementia. Deprescribing efforts for PWD should focus not only on potentially harmful central nervous system-active medications but also on other classes such as PPIs and NSAIDs.

The Mediating Role of Social Participation in Motoric Cognitive Risk and its Relation to Depression and Loneliness in Older Adults

BACKGROUND

Motoric cognitive risk syndrome (MCR) reduces the quality of life, independence, and social interaction in older adults. Social participation is a potentially modifiable factor that benefits cognitive and mental health. This study explored the mediating roles of social participation between MCR and depression and between MCR and loneliness.

METHODS

We performed a secondary analysis of data from the 2015-2016 National Social Life, Health, and Aging Project. Slow gait speed and cognitive decline were used to assess MCR. Mediation analysis was applied to two models, both of which used MCR as an exposure and social participation as a mediator. The outcomes were depression and loneliness for each model, respectively.

RESULTS

Among 1,697 older adults, 196 (11.6%) had MCR. The mediating role of social participation was statistically significant in both models. The indirect effect (β=0.267, p=0.001) of MCR on depression through social participation comprised 11.97% of the total effect (β=2.231, p&lt;0.001). The indirect effect (β=0.098, p=0.001) of MCR on loneliness through social participation was 19.48% of the total effect (β=0.503, p&lt;0.001).

CONCLUSION

Interventions to increase social participation may reduce depression and loneliness of older adults with MCR.

Prevalence of visual impairment in older people living with dementia and its impact: a scoping review

BACKGROUND AND OBJECTIVES

Visual impairment (VI) and dementia both increase with age, and it is likely that many older people are living with both conditions. This scoping review aims to investigate the prevalence and types of VI among older people living with dementia, and the impact of VI on older people living with dementia and their caregivers.

METHODS

This scoping review used Arksey and O'Malley's methodological framework. Studies in any setting involving people living with dementia and some assessment of either VI, eye diseases causing VI or the impact of VI were included.

RESULTS

Thirty-six studies were included. Thirty-one studies reported the prevalence of VI in older people living with dementia, while ten studies reported on impacts of VI on people living with dementia. Only one study reported on impacts on caregivers. The prevalence of VI or specific eye diseases among older people living with dementia ranged from 0.2 to 74%. The impacts of VI on older people living with dementia included increased use of hospital services, increased disability and dependency, reduced social engagement, negative emotions, increased abnormal behaviours, loss of hobbies, difficulty in using visual aids or memory aids, and greater Neuropsychiatric Inventory symptoms. And the impacts on caregivers included increased conflict and physical exhaustion.

CONCLUSION

VI is common in older people living with dementia and is associated with negative impacts on those with dementia and their caregivers. However, heterogeneity between studies in terms of setting and method for assessing and defining VI make it difficult to compare findings among studies. Further research is needed, particularly assessing the impact on caregivers.

Development of an Advance Care Planning Portal-Based Tool for Community-Dwelling Persons Living With Cognitive Impairment: The ACPVoice Tool

Background: Patient portals can be an innovative and efficient way to engage patients in advance care planning (ACP). However, comprehension and judgment in older adults with cognitive impairment presents several barriers and challenges to engaging in new technology. Our objective was to develop an ACP portal-based tool (ACPVoice) for community-dwelling persons living with cognitive impairment (PLCI) by engaging end-users in the design process. Methods: Two rounds of cognitive interviews were conducted to identify and resolve cognitive issues related to comprehension, judgment, response, and to assess content validity. Purposive sampling was used with the goal of enrolling 15 different participants (five with mild cognitive impairment and five dyads (those with mild dementia and their care partner) in each round to assess respondents' understanding of questions related to advance care planning to be administered via the patient portal. Results: Twenty PLCI (mean age 78.4, 10 females [50%]) and ten care partners (mean age 60.9, 9 females [90%]) completed cognitive interviews between May 2021 and October 2021. The mean Mini-Mental State Examination score for PLCI was 25.6 (SD 2.6). Unclear wording and undefined vague and/or unfamiliar terms were the major issues identified. Revisions to item wording, response options, and instructions were made to improve question comprehension and response as well as navigational ease. Conclusion: Minor changes to the wording, format, and response options substantially improved respondents' ability to interpret the item content of the ACPVoice tool. Dissemination and implementation of the ACPVoice tool could help to engage community-dwelling PLCI in ACP discussions.

A Description of Persons With Alzheimer Disease and Related Dementias Receiving Home Health Care: A National Analysis

The end-of-life period of individuals with Alzheimer disease and related dementias receiving home health care (HHC) is understudied. We sought to describe characteristics of HHC patients with Alzheimer disease and related dementias at risk of death within a year, based on clinician assessment. We conducted a secondary data analysis of a 5% random sample of the Outcome and Assessment Information Set data set for the year 2017. We used Outcome and Assessment Information Set-C item M1034 to identify HHC patients with overall status of progressive condition leading to death within a year. Multivariable logistic regression model was used to examine the association between sociodemographic, functional, clinical, and caregiving factors and likelihood of decline leading to death within a year, as identified by HHC clinicians. Clinician perception of decline leading to death within a year was higher for Whites (vs Blacks or Hispanics) (odds ratio [OR], 0.74 [95% confidence interval (CI), 0.69-0.80], and OR, 0.63 [95% CI, 0.57-0.69], respectively). Factors associated with increased odds of decline leading to death within a year included daily pain (OR, 1.11 [95% CI, 1.06-1.17]), anxiety daily or more often (OR, 1.58 [95% CI, 1.49-1.67]), shortness of breath (OR, 1.45 [95% CI, 1.34-1.57]), use of oxygen (OR, 1.60 [95% CI, 1.52-1.69]), disruptive behavior (OR, 1.26 [95% CI, 1.20-1.31]), and feeding difficulty (OR, 2.25 [95% CI, 2.09-2.43]). High symptom burden exists among HHC patients with Alzheimer disease and related dementias identified to have a status of decline leading to death within a year.

Hospice Improves Care Quality For Older Adults With Dementia In Their Last Month Of Life

The Medicare hospice benefit was originally designed around a cancer disease paradigm but increasingly serves people living with dementia. At this time, almost half of all older adults receiving hospice care have dementia. Yet there is minimal evidence as to whether hospice benefits people living with dementia outside of nursing facilities. We asked whether and how the perceived quality of last-month-of-life care differed between people with and without dementia and whether hospice use among people living with dementia was associated with perceived quality of care compared with the quality of care for those who did not use hospice. We used nationally representative data from the National Health and Aging Trends Study and Medicare claims from the period 2011-17 to examine the impact of hospice enrollment on proxy perceptions of last-month-of-life care quality. Proxies of people living with dementia enrolled in hospice compared with proxies of those not enrolled more often reported care to be excellent (predicted probability: 52 percent versus 41 percent), more often reported having anxiety or sadness managed (67 percent versus 46 percent), and less often reported changes in care settings in the last three days of life (10 percent versus 25 percent). There were no differences in the impact of hospice on proxy ratings of care for people with and without dementia. Policy makers should consider these benefits when weighing changes to hospice policy and regulations that may affect people living with dementia.

Trends in US Medicare Decedents’ Diagnosis of Dementia From 2004 to 2017

Question

To what degree did the diagnosis of Alzheimer disease and related dementias (ADRD) change at the end of life between 2004 and 2017?

Findings

Among 3 515 329 Medicare fee-for-service decedents, the percentage who received an ADRD diagnosis within 2 years of death increased from 34.7% in 2004 to 47.2% in 2017. The likelihood of receiving an ADRD diagnosis particularly increased in the inpatient, hospice, and home health settings; individual characteristics and service use were stable over time, while the intensity of end-of-life care declined on most measures.

Meaning

Dying with an ADRD diagnosis has become more common among older US decedents, potentially owing to increased awareness and temporal changes in billing.

Importance

Alzheimer disease and related dementias (ADRD) have received considerable attention among clinicians, researchers, and policy makers in recent years. Despite increased awareness, few studies have documented temporal changes in the documentation of ADRD diagnoses despite its new importance for risk adjustment for health plans in Medicare.

Objective

To assess trends in frequency of ADRD diagnosis in the last 2 years of life from 2004 to 2017, as well as any associated changes in billing practices, characteristics of the population with diagnosed ADRD, and intensity of end-of-life care.

Design, Setting, and Participants

This is a serial cross-sectional study of older adult decedents (67 years or older) from 2004 to 2017 using a 20% sample of fee-for-service Medicare decedents. An ADRD diagnosis within the last 2 years of life was identified using diagnosis codes from inpatient, professional service, home health, or hospice claims, requiring the standard claims algorithm that required at least 1 claim and a more stringent algorithm that required at least 2 claims. Trends in ADRD diagnosis among decedents were used to lessen influence of new diagnostic technologies for early stage disease. Demographic characteristics, selected comorbidities, place of death, and health service use at the end-of-life were also examined. Data were analyzed from July 9, 2020, to May 3, 2021.

Exposures

Calendar year 2004 to 2017.

Main Outcome and Measure

An ADRD diagnosis within 2 years of death.

Results

Among the included 3 515 329 Medicare fee-for-service decedents, when adjusted for age and sex, the percentage of older decedents with an ADRD diagnosis increased from 34.7% in 2004 to 47.2% in 2017. The trend was attenuated (25.2% to 39.2%) using a stringent ADRD definition. There was an inflection in the curve from 2011 to 2013, the time at which additional diagnoses were added to Medicare claims and the National Alzheimer Care Act was enacted. The ADRD diagnosis frequency increased considerably in inpatient (49.0% to 67.3%), hospice (12.2% to 42.0%), and home health (10.1% to 28.7%) claims. However, individual characteristics, number of visits, and hospitalizations were similar across the study period, and the intensity of end-of-life care declined on most measures.

Conclusions and Relevance

In this cross-sectional study, nearly half of older Medicare decedents had a diagnosis of ADRD at the time of death. From 2004 to 2017, the percentage of older adult decedents who received an ADRD diagnosis increased substantially prior to announcement of the addition of ADRD to Medicare risk adjustment strategies.

Development of a Longitudinal Dataset of Persons With Dementia and Their Caregivers Through End-of-Life: A Statistical Analysis System Algorithm for Joining National Health and Aging Trends Study/National Study of Caregiving

Background: Alzheimer’s disease and related dementias (AD/ADRD) are terminal conditions impacting families and caregivers, particularly at end-of-life. Longitudinal, secondary data analyses present opportunities for insight into dementia caregiving and decision-making over time; however, joining complex datasets and preparing them for analysis poses many challenges. Objectives: To describe an approach to linking national survey data of older adults with their primary caregivers to build a prospective, longitudinal dataset, and to share the Statistical Analysis System (SAS) coding statement algorithms with other researchers. Methods: The National Health and Aging Trends Study (NHATS) and National Study of Caregiving (NSOC) are joined using a series of algorithms based on conceptual and operational definitions of dementia, primary caregivers, and the occurrence of death. A series of SAS algorithms resulting in the final longitudinal dataset was created. Results: NHATS/NSOC participants were linked using three preliminary data files (n = 12 427) and one final data join (n = 3305) over nine rounds of data collection. Presence of dementia was defined based on the indicator in the year preceding the last month-of-life (LML) interview. Primary caregivers were defined as the person providing the most frequent care over time. Additional flag variables (LML interview, dementia classification, and cohort (2011 vs 2015)) were created. The SAS algorithms are presented herein. Discussion: The SAS coding statement algorithms provide an opportunity to conduct longitudinal analysis of care for both members of the dyad in the context of dementia and end-of-life. Future research using the proposed dataset can further explore care and caregiving in these populations.

Symptom Burden and Activity of Daily Living (ADL) Dependency Among Home Health care Patients Discharged to Home Hospice

Background: We sought to examine sociodemographic and clinical characteristics present on admission to HHC associated with discharge to hospice. Methods: We used a 5% random sample of 2017 national Outcome and Assessment Information Set (OASIS) data. A Cox proportional hazards regression model was estimated for the primary outcome (discharge to hospice) to examine the associations with sociodemographic and clinical characteristics of HHC patients. Results: Among 489, 230 HHC patients, 4268 were discharged to hospice. The median (interquartile range) length of HHC stay for patients discharged to hospice care was 33 (14-78) days. Compared to White patients, Black, Hispanic, and other race, (hazard ratio [HR] = .50 [95% confidence interval, CI = .44-.57]), (HR = .53 [95% CI = .46-.62]), and (HR = .49 [95% CI = .40-.61], respectively) was associated with shorter time to discharge to hospice care. Clinical characteristics including severe dependence in activities of daily (ADL) (HR = 1.68 [95% CI = 1.01-2.78]), cognitive impairment (HR = 1.10 [95% CI = 1.01-1.20]), disruptive behavior daily (HR = 1.11 [95% CI = 1.02-1.22]), and inability to feed oneself (HR = 4.78, 95% CI = 4.30, 5.31) was associated with shorter time to discharge to hospice. Symptoms of anxiety daily (HR = 1.55 [95% CI = 1.43-1.68]), and pain daily or all the time (HR = 1.54 [95% CI = 1.43-1.64]) were associated with shorter time to discharge to hospice. Conclusions: High symptom burden, ADL dependency, and cognitive impairment on admission to HHC services was associated with greater likelihood of discharge to hospice.

Aliviado Mobile App for Hospice Providers: A Usability Study

CONTEXT

Evaluation of usability and mobile health content is critical for ensuring effective implementation of technology utilizing interventions tailored to the needs of hospice care providers for people living with dementia in community-based settings.

OBJECTIVES

To evaluate the usability, content, and "readiness to launch" of the Aliviado mobile health app for interdisciplinary team members participating in the Hospice Advanced Dementia Symptom Management and Quality of Life.

METHODS

Usability of the Aliviado app was assessed in 86 respondents with an adapted IBM Computer Usability Satisfaction Questionnaire following Hospice Advanced Dementia Symptom Management and Quality of Life training and implementation of the mobile app.

RESULTS

More than half of users receiving training employed the mobile app in practice. Users reported use as: Daily-6.3%, Weekly-39.6%, monthly-54.2%. The highest measured attributes were usefulness, value, and effectiveness. Over 90% deemed the app "ready to launch" with no or minimal problems.

CONCLUSION

This study shows that a newly-developed mobile app is usable and can be successfully adopted for care of people living with dementia.

Latent Class Analysis of Symptom Burden Among Seriously Ill Adults at the End of Life

BACKGROUND

Serious illness is characterized by high symptom burden that negatively affects quality of life (QOL). Although palliative care research has highlighted symptom burden in seriously ill adults with cancer, symptom burden among those with noncancer serious illness and multiple chronic conditions has been understudied. Latent class analysis is a statistical method that can be used to better understand the relationship between severity of symptom burden and covariates, such as the presence of multiple chronic conditions. Although latent class analysis has been used to highlight subgroups of seriously ill adults with cancer based on symptom clusters, none have incorporated multiple chronic conditions.

OBJECTIVES

The objectives of this study were to (a) describe the demographic and baseline characteristics of seriously ill adults at the end of life in a palliative care cohort, (b) identify latent subgroups of seriously ill individuals based on severity of symptom burden, and (c) examine variables associated with latent subgroup membership, such as QOL, functional status, and the presence of multiple chronic conditions.

METHODS

A secondary data analysis of a palliative care clinical trial was conducted. The latent class analysis was based on the Edmonton Symptom Assessment System, which measures nine symptoms on a scale of 0-10 (e.g., pain, fatigue, nausea, depression, anxiousness, drowsiness, appetite, well-being, and shortness of breath). Clinically significant cut-points for symptom severity were used to categorize each symptom item in addition to a categorized total score.

RESULTS

Three latent subgroups were identified (e.g., low, moderate, and high symptom burden). Lower overall QOL was associated with membership in the moderate and high symptom burden subgroups. Multiple chronic conditions were associated with statistically significant membership in the high symptom burden latent subgroup. Older adults between 65 and 74 years had a lower likelihood of moderate or high symptom burden subgroup membership compared to the low symptom burden class.

DISCUSSION

Lower QOL was associated with high symptom burden. Multiple chronic conditions were associated with high symptom burden, which underlines the clinical complexity of serious illness. Palliative care at the end of life for seriously ill adults with high symptom burden must account for the presence of multiple chronic conditions.

Prognostic Awareness, Disease and Palliative Understanding Among Caregivers of Patients With Dementia

BACKGROUND

Persons with dementia (PwD) often have significant cognitive deficits and functional limitations, requiring substantial caregiver assistance. Given the high symptom burden and terminal nature of dementia, good prognostic awareness and integration of palliative care (PC) is needed.

OBJECTIVE

To evaluate prognostic awareness, disease, and PC understanding among caregivers of PwD and to assess for improvements in routine care.

DESIGN

A cross-sectional study of 2 cohorts at a single-academic medical center. Surveys were mailed to 200 caregivers of PwD in 2012 (cohort 1). Surveys were sent to new subset of caregivers of PwD (n = 80) in 2018 (cohort 2) to assess trends over time.

RESULTS

A total of 154 of caregivers completed the survey (response rate 55%). Compared to 2012, a higher proportion of caregivers in 2018 reported having conversations about prognosis with PwD's physicians (25% in 2012 vs 45% in 2018; P = .027). However, a large percentage (43% in 2012 and 40% in 2018) of caregivers reported no understanding of the PwD's prognosis. Despite most stating dementia was not curable, only 39% in 2012 and 52% in 2018 (P = .015) understood that dementia was a terminal disease. In addition, only 32% in 2012 and 40% in 2018 (P = .39) felt that they were knowledgeable about PC.

CONCLUSIONS

Prognostic discussions between caregivers of PwD and the PwD's physicians may be occurring more often; however, a high percentage of caregivers report a poor understanding about the terminal nature of dementia and the role of PC.

Health and Well-Being in the Year before Death: The Association with Quality of Life and Care at the End-of-Life

Objective: We examined whether older adults' health and well-being during their final year of life predicts end-of-life (EOL) quality of life (QOL) and quality of care (QOC). Methods: Using data from deceased participants (n = 1125) in the 2011-2015 National Health and Aging Trends Study, we performed latent class analysis to identify profiles of health and well-being, and we examined the association between these classes and EOL QOL and QOC. Results: Four classes were identified: healthy/happy (20%), frail/happy (37%), cognitively impaired/moderately distressed (27%), and highly impaired/highly distressed (16%). Persons in the highly impaired/highly distressed class showed a poorer QOL at the EOL, whereas those in the healthy/happy class reported a lower level of QOC at the EOL. Discussion: The benefits of maintaining health and well-being often carry forward to EOL. Older adults with high impairment and distress merit greater attention such as assuring care and advance care plans.
