RESUMO

PURPOSE: To describe emotional barriers and facilitators to deprescribing (the planned reduction or discontinuation of medications) in older adults with cancer and polypharmacy. METHODS: Virtual focus groups were conducted over Zoom with 5 key informant groups: oncologists, oncology nurses, primary care physicians, pharmacists, and patients. All groups were video- and audio-recorded and transcribed verbatim. Focus group transcripts were analyzed using inductive content analysis, and open coding was performed by two coders. A codebook was generated based on the initial round of open coding and updated throughout the analytic process. Codes and themes were discussed for each transcript until consensus was reached. Emotion coding (identifying text segments expressing emotion, naming the emotion, and assigning a label of positive or negative) was performed by both coders to validate the open coding findings. RESULTS: All groups agreed that polypharmacy is a significant problem. For clinicians, emotional barriers to deprescribing include fear of moral judgment from patients and colleagues, frustration toward patients, and feelings of incompetence. Oncologists and patients expressed ambivalence about deprescribing due to role expectations that physicians "heal with med[ication]s." Emotional facilitators of deprescribing included the involvement of pharmacists, who were perceived to be neutral, discerning experts. Pharmacists described emotionally aware communication strategies when discussing deprescribing with other clinicians and expressed increased awareness of patient context. CONCLUSION: Deprescribing can elicit strong and predominantly negative emotions among clinicians and patients which could inhibit deprescribing interventions. The involvement of pharmacists in deprescribing interventions could mitigate these emotional barriers. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05046171 .

RESUMO

Gait speed significantly affects functional status and health outcomes in older adults. This cross-sectional study evaluated cognitive and physical fitness contributors to usual and peak gait speed in persons with Alzheimer's dementia. Multiple hierarchal linear regression was used to obtain squared semipartial correlation coefficients (sr2) and effect sizes (Cohen's ƒ2). Participants (n = 90; 56% male) averaged 77.1 ± 6.6 years of age and 21.8 ± 3.4 on Mini-Mental State Examination. Demographic/clinical, physical fitness, and cognition variables explained 45% and 39% of variance in usual and peak gait speed, respectively. Muscle strength was the only significant contributor to both usual (sr2 = .175; Cohen's ƒ2 = 0.31; p < .001) and peak gait speed (sr2 = .11; Cohen's ƒ2 = 0.18; p < .001). Women who were "slow" walkers (usual gait speed <1.0 m/s) had significantly lower cardiorespiratory fitness and executive functioning compared with "fast" walkers. In conclusion, improving muscle strength may modify gait and downstream health outcomes in Alzheimer's dementia.

RESUMO

Over half of older adults experience polypharmacy, including medications that may be inappropriate or unnecessary. Deprescribing, which is the process of discontinuing or reducing inappropriate and/or unnecessary medications, is an effective way to reduce polypharmacy. This review summarizes (1) the process of deprescribing and conceptual models and tools that have been developed to facilitate deprescribing, (2) barriers, enablers, and factors associated with deprescribing, and (3) characteristics of deprescribing interventions in completed trials, as well as (4) implementation considerations for deprescribing in routine practice. In conceptual models of deprescribing, multilevel factors of the patient, clinician, and health-care system are all related to the efficacy of deprescribing. Numerous tools have been developed for clinicians to facilitate deprescribing, yet most require substantial time and, thus, may be difficult to implement during routine health-care encounters. Multiple deprescribing interventions have been evaluated, which mostly include one or more of the following components: patient education, medication review, identification of deprescribing targets, and patient and/or provider communication about high-risk medications. Yet, there has been limited consideration of implementation factors in prior deprescribing interventions, especially with regard to the personnel and resources in existing health-care systems and the feasibility of incorporating components of deprescribing interventions into the routine care processes of clinicians. Future trials require a more balanced consideration of both effectiveness and implementation when designing deprescribing interventions.

RESUMO

OBJECTIVES: To examine the added effect of having both cognitive deficit and physical frailty, compared to having either one only, on hospitalization and emergency department (ED) visits. METHODS: Data from a population-based study of 3,157 community-dwelling older (≥60 years) Chinese adults in the U.S. were used. Cognitive deficit was measured by the Mini-Mental State Examination (i.e. education-adjusted score: 16 [illiterate], 19 [primary school], and 23 [≥middle school]). Physical frailty was identified using the Short Performance Physical Battery (0-6 out of 15). The numbers of hospitalizations and ED visits in the previous two years were self-reported. RESULTS: In this sample, 12.63% had cognitive deficit alone, 5.95% had physical frailty alone, and 4.26% had both. Compared with participants having neither cognitive deficit nor physical frailty, those having physical frailty alone were 1.5 times as likely to have hospitalizations (Rate Ratio [RR] = 1.52 [1.07, 2.16], p = 0.02) and ED visits (RR = 1.52 [1.07, 2.15], p = 0.02). Having cognitive deficit alone was not significantly related to either outcome. However, having cognitive deficit with existing physical frailty increased the likelihood of both hospitalization (RR = 2.00 [1.36, 2.96], p < 0.001) and ED visits (RR = 2.04 [1.37, 3.03], p < 0.001) to a greater extent than having physical frailty alone. CONCLUSION: Having cognitive deficit alone was not significantly related to the likelihood of hospitalizations or ED visits, however having cognitive deficit with existing physical frailty increased the likelihood of both outcomes to a greater degree than having physical frailty alone. This suggests cognitive deficit and physical frailty have synergistic effects on hospitalizations and ED visits.

RESUMO

BACKGROUND: Pain is common yet under-studied among older Medicare home health (HH) patients with Alzheimer's disease and related dementias (ADRD). AIMS: Examine (1) the association between ADRD and severe pain in Medicare HH patients; and (2) the impact of severe pain and ADRD on unplanned facility admissions in this population. DESIGN: Analysis of the Outcome and Assessment Information Set (OASIS) and Medicare claims data. SETTINGS/PARTICIPANTS: 6,153 patients ≥65 years receiving care from a nonprofit HH agency in 2017. METHODS: Study outcomes included presence of severe pain and time-to-event measures of unplanned facility admissions (hospital, nursing home, or rehabilitation facilities). ADRD was identified using ICD-10 diagnosis codes and cognitive impairment symptoms. Logistic regression and Cox proportional hazard models were used to examine, respectively, the association between ADRD and severe pain, and the independent and interaction effects of severe pain and ADRD on unplanned facility admission. RESULTS: Patients with ADRD (n = 1,525, 24.8%) were less likely to have recorded severe pain than others (16.4% vs. 23.6%, p < .001). Adjusting for demographics, comorbidities, mental and physical functional status, and use of HH services, having severe pain was related to a 35% increase (hazard ratio [HR] = 1.35, p = .002) in the risk of unplanned facility admission, but the increase in such risk was the same whether or not the patient had ADRD. CONCLUSIONS: HH patients with ADRD may have under-recognized pain. Severe pain is a significant independent predictor of unplanned facility admissions among HH patients.

RESUMO

Patients in home health care (HHC), a rapidly growing healthcare sector, are at high risk for infections. This study aimed to identify risk factors for infections among HHC patients using the Outcome and Assessment Information Set (OASIS) data. We used a 5% random sample of the 2013 national OASIS data. Infections were identified if records indicated that patients were hospitalized or received emergency care for one of three types of infections (respiratory, wound site, and urinary tract infection). Multivariate logistic regression models were used to identify risk factors for each individual infection type. The final analysis included 128,163 patients from 8,255 HHC agencies nationwide. Approximately 3.2% of the patients developed infections during their HHC stay that led to hospitalization or emergency care treatment. We found that associations between demographics and infection risk are specific to the type of infection. In general, a history of multiple hospitalizations in past 6 months, comorbidity, having a severe condition at HHC admission, and impaired physical functioning increased HHC patients' risk of infections. We also identified that HHC patients with caregivers who needed training in providing medical procedure or treatment are at higher risk for wound-site infections. Our findings suggest that patients with underlying medical conditions and limited physical function status are more likely to develop infection. The caregiver's lack of training in providing needed care at home also places HHC patients at high risk for infection. Education for patients and caregivers should be tailored based on their health literacy level to ensure complete understanding.

RESUMO

BACKGROUND: Alcohol use and its associated problems are on the rise in China. In this study, we examined the associations between alcohol use and cognitive functioning in a representative sample of adults aged 45 years and older in China. METHODS: Baseline data for 16,328 participants of the China Health and Retirement Longitudinal Study were analyzed. Alcohol use was measured by drinking status (never, former, moderate, and at-risk drinkers), number of standard drinks per week, and years of drinking. Cognitive functioning was assessed for visuospatial ability, episodic memory, orientation/attention, and overall cognitive functioning. Multivariate linear and logistic regressions were used to examine the independent association between alcohol use and cognitive functioning controlling for age, gender, education, domestic partner status, and depressive symptoms. RESULTS: The study participants were, on average, 66 years old (median 59, range 45 to 102). The prevalence of ever drinking during lifetime and current at-risk drinking (>14 drinks per week) in this population was 34.6 and 6.7%, respectively. Drinking was more common among men with 48.8% being ever drinkers and 14.4% current at-risk drinkers, respectively. At-risk drinkers, compared to people who never drank alcohol, had worse episodic memory (ß = -0.11, p = 0.048). Moreover, number of standard drinks per week was associated with worse episodic memory (ß = -0.001, p = 0.02). None of the other measures of alcohol use was associated with the overall or domain-specific cognitive functioning. CONCLUSIONS: At-risk drinking status was associated with worse episodic memory. Clinicians should incorporate alcohol use assessment into routine care for middle-aged and older adults in China and provide them with resources and strategies to effectively manage their alcohol use. This may help preserve episodic memory in this population.

RESUMO

OBJECTIVES: To examine pain interference in verbally communicative older adults with mild to moderate Alzheimer's disease (AD) and to examine the association of pain interference with cognitive function and depressive symptoms. METHOD: For this pilot study, we used a cross-sectional design to examine pain interference (Brief Pain Inventory-Short Form), cognitive function (Mini-Mental State Exam), and depressive symptoms (15-item Geriatric Depression Scale) in 52 older (≥65) communicative adults with AD who reported being free from chronic pain requiring daily analgesics. RESULTS: Pain was reported to interfere with general activity (13.5%), mood (13.5%), walking ability (13.5%), normal work (11.5%), enjoyment of life (11.5%), relationships with other people (9.6%), and sleep (9.6%). Pain interference was significantly positively correlated with both cognitive function (rs = 0.46, p = 0.001) and depressive symptomology (rs = 0.45, p = 0.001), indicating that greater reported pain interference was associated with better cognitive function and more depressive symptoms. CONCLUSION: Among older people with AD who report being free from chronic pain requiring daily analgesics, 2 in 10 are at risk of pain interference and depressive symptoms. Those with better cognitive function reported more pain interference and depressive symptoms, meaning pain is likely to be under-reported as AD progresses. Clinicians should regularly assess pain interference and depressive symptoms in older persons with AD to identify pain that might be otherwise overlooked..

RESUMO

The objectives of this study were (1) to describe home health care (HHC) nurses' perception of and care processes related to geriatric depression and frailty, and (2) to identify barriers to care delivery for older persons with these two conditions. Ten semi-structured interviews were conducted with HHC nurses, and 16 HHC nursing visits to 16 older patients (≥65 years) were observed. Mixed method analysis showed that HHC nurses did not routinely assess for frailty and depression. Major barriers to care delivery included insufficient training, documentation burden, limited reimbursement, and high caseload. Addressing these barriers would facilitate HHC nursing care for frail, depressed elders.

RESUMO

BACKGROUND: Current evidence on mental health disorders (MHDs) in the U.S. elderly home care population is highly varied and limited to the local level. AIM: The objective of this study was to examine the prevalence and characteristics of U.S. elders with MHDs on the national level. METHODS: This is a primary analysis of secondary use data from a 5% random sample of the 2010 National Outcome and Assessment Information Set (OASIS) data spanning a 60-day home care session. MHDs included depression, anxiety, substance abuse, psychotic disorders, aggression, and socially inappropriate behaviors and were identified by diagnosis, symptoms, or mental health service order in the plan of care. Logistic regression was used to identify correlates of MHD. RESULTS: The final analysis was conducted on records from 28,475 elderly patients with an average age of 79 (range 65-110). Patients were primarily female, White, Medicare beneficiaries, referred from short-stay acute hospitals, and living with others at home. Prevalence of MHDs was approximately 40%; depression (28.0%) and anxiety (18.9%) were common. Factors associated with MHDs were younger age, female, smokers, frail, living alone, referred from psychiatric hospitals, cognitively or sensory impaired, poorer health status, recent history of falls or multiple hospitalizations, and insufficient social support. Only about one third of patients identified with MHD received mental health services during the 60-day home care episode, including psychiatric nursing services and depression interventions. DISCUSSION: MHDs are a national health concern in the older U.S. home care population and are common but largely undermanaged. Future research in the home care sector should be aimed at developing targeted MHD screening and interventional protocols and training the current workforce, as well as expanding the future workforce to improve psychiatric care for the homebound elderly.

RESUMO

The current study examined longitudinal associations between mental disorders and all-cause subsequent medical events in a 5% random sample of records in the 2010 national Outcome and Assessment Information Set. Records of older adults (N = 28,475) receiving home health care (HHC) services were examined with respect to mental disorders and medical events, including acute care hospitalization, emergency department admission, and 30-day rehospitalization. Predominant mental disorders were depression and anxiety identified by formal diagnoses, symptom clusters, and/or prescription of related mental health services. Depression intervention use was the strongest risk factor for all three types of medical events. However, 61.6% of patients receiving depression interventions did not screen positive at admission using the Patient Health Questionnaire-2. Moving forward, nurses must closely monitor high-risk older adults throughout the HHC stay using sensitive depression screening tools, as well as receive targeted training in geriatric psychiatry.

RESUMO

Home care is the fastest growing U.S. health care sector, serving a predominance of highly vulnerable elderly patients. Mental health disorders (MHDs) are a major health concern in this population, however, current knowledge regarding their occurrence and associated correlates is inadequate. To address this gap, this integrative review examined existing findings regarding the prevalence and correlates of MHDs in home care elders. A search of six electronic databases and a hand search produced a final group of 36 articles for review. Poor data representativeness and methodological limitations impacted the quality of these studies, as reflected in an extremely wide range of prevalence estimates for these disorders (12% - 62%). A number of recommendations are made with respect to future research in this area. These include conducting multi-site investigations and the use of consistent and clear protocols for identification of MHDs in home care elders, a growing and significantly under-served population.

RESUMO

BACKGROUND: Home time is an important patient-centric quality metric, which has been largely unexamined among assisted living (AL) residents. Our objectives were to assess variation in home time among AL residents in the year following admission and to examine the associations with state regulations for direct care workers (DCW) training and staffing and for licensed nurse staffing. METHODS: Medicare beneficiaries who entered AL communities in 2018 were identified, and their home time in the year following admission was measured. Home time was calculated as the percentage of time spent at home per day being alive. Resident characteristics and state regulations in DCW staffing, DCW training, and licensed staffing were measured. We used a multivariate linear regression model with AL-level fixed effects to estimate the relationship between person-level characteristics and home time. Linear regression models adjusting for resident characteristics were used to estimate the association between state regulations and residents' home time. RESULTS: The study sample included 59,831 new Medicare beneficiary residents in 12,143 ALs. In the year following AL admission, residents spent 94% (standard deviation = 14.6) of their time at home. Several resident characteristics were associated with lower home time: Medicare-Medicaid dual eligibility, having more chronic conditions, and specific chronic conditions, for example, dementia. In states with greater regulatory specificity for DCW training and staffing, and lower specificity for licensed staffing, residents had longer adjusted home time. CONCLUSION/IMPLICATIONS: Home time varied substantially among AL residents depending on resident characteristics and state-level regulatory specificity. AL residents eligible for Medicare and Medicaid had substantially shorter home time than the Medicare-only residents, largely due to longer time spent in nursing homes. State AL regulatory specificity for DCWs and licensed staff also impacted AL residents' home time. These findings may guide AL operators and state legislators in efforts to improve this important quality of life metric.

RESUMO

OBJECTIVES: Medications with a higher risk of harm or that are unlikely to be beneficial are used by nearly all older patients in home health care (HHC). The objective of this study was to understand stakeholders' perspectives on challenges in deprescribing these medications for post-acute HHC patients. DESIGN: Qualitative individual interviews were conducted with stakeholders involved with post-acute deprescribing. SETTING AND PARTICIPANT: Older HHC patients, HHC nurses, pharmacists, and primary/acute care/post-acute prescribers from 9 US states participated in individual qualitative interviews. MEASURES: Interview questions were focused on the experience, processes, roles, training, workflow, and challenges of deprescribing in hospital-to-home transitions. We used the constant comparison approach to identify and compare findings among patient, prescriber, and pharmacist and HHC nurse stakeholders. RESULTS: We interviewed 9 older patients, 11 HHC nurses, 5 primary care physicians (PCP), 3 pharmacists, 1 hospitalist, and 1 post-acute nurse practitioner. Four challenges were described in post-acute deprescribing for HHC patients. First, PCPs' time constraints, the timing of patient encounters after hospital discharge, and the lack of prioritization of deprescribing make it difficult for PCPs to initiate post-acute deprescribing. Second, patients are often confused about their medications, despite the care team's efforts in educating the patients. Third, communication is challenging between HHC nurses, PCPs, specialists, and hospitalists. Fourth, the roles of HHC nurses and pharmacists are limited in care team collaboration and discussion about post-acute deprescribing. CONCLUSIONS AND IMPLICATIONS: Post-acute deprescribing relies on multiple parties in the care team yet it has challenges. Interventions to align the timing of deprescribing and that of post-acute care visits, prioritize deprescribing and allow clinicians more time to complete related tasks, improve medication education for patients, and ensure effective communication in the care team with synchronized electronic health record systems are needed to advance deprescribing during the transition from hospital to home.

RESUMO

THEMIS plays an indispensable role in T cells, but its mechanism of action has remained highly controversial. Using the systematic proximity labeling methodology PEPSI, we identify THEMIS as an uncharacterized substrate for the phosphatase SHP1. Saturated mutagenesis assays and mass spectrometry analysis reveal that phosphorylation of THEMIS at the evolutionally conserved Tyr34 residue is oppositely regulated by SHP1 and the kinase LCK. Similar to THEMIS-/- mice, THEMISY34F/Y34F knock-in mice show a significant decrease in CD4 thymocytes and mature CD4 T cells, but display normal thymic development and peripheral homeostasis of CD8 T cells. Mechanistically, the Tyr34 motif in THEMIS, when phosphorylated upon T cell antigen receptor activation, appears to act as an allosteric regulator, binding and stabilizing SHP1 in its active conformation, thus ensuring appropriate negative regulation of T cell antigen receptor signaling. However, cytokine signaling in CD8 T cells fails to elicit THEMIS Tyr34 phosphorylation, indicating both Tyr34 phosphorylation-dependent and phosphorylation-independent roles of THEMIS in controlling T cell maturation and expansion.

RESUMO

Life-limiting childhood illness is a traumatic experience presenting parents with psychological, physical, and social challenges. While cultural influences affect all parents coping with the life-limiting illness and end-of-life period of their child, little is known about the experiences of Chinese American parents. The purpose of this comprehensive literature review was to describe Chinese American parents' experiences during their children's end-of-life period from a culturally informed perspective. Important themes in the literature are revealed including culture-based phenomena regarding philosophy of life and illness that can affect treatment choices, cultural mores that influence parental behaviour in Western health-care systems, specific communication patterns within families and between families and providers, certain coping risks, and gender-based roles and caregiving activities that have implications for provider communication patterns. The findings are consonant with the larger literature regarding the impact of traditional culture and values on Chinese family and health behaviours. Health professionals must be sensitive to Chinese American parents' communication styles, unspoken concerns, and unresolved cultural conflicts in American health-care settings. Educational interventions may be very helpful in this regard.

RESUMO

BACKGROUND: Despite the rapid growth of assisted living (AL) communities and the increasing similarity between AL and nursing home (NH) populations, little is known about the characteristics of older adults at the time of AL admission and how these characteristics compare to individuals newly admitted to NH from the community. This study examined the individual, facility, and geographic factors associated with new AL admission. METHODS: This retrospective descriptive study used data from the national Medicare enrollment and claims datasets, the Minimum Data Set, and the Medicare Provider Analysis and Review. The study cohort included 158,124 Medicare beneficiaries newly admitted to ALs and 715,261 newly admitted to NHs during 10/2017-10/2019. Multinomial logistic regression analysis and logistic regression analysis were conducted to examine factors associated with new admissions. RESULTS: Demographic, socioeconomic, and health service use characteristics were associated with new admission to long-term care. Specifically, Medicare fee-for-service beneficiaries, those age 75 years and older, male, having one skilled nursing facility (SNF) stay or any hospital stay in the past 6 months are more likely to be newly admitted to AL, whereas those who are dually eligible, racial/ethnic minorities, and having two or more SNF stays in the past 6 months are more likely to be admitted to an NH. CONCLUSION: There are substantial differences between individuals who are newly admitted from the community to AL versus those to NH.

RESUMO

BACKGROUND: Existing literature on online reviews of healthcare providers generally portrays online reviews as a useful way to disseminate information on quality. However, it remains unknown whether online reviews for assisted living (AL) communities reflect AL care quality. This study examined the association between AL online review ratings and residents' home time, a patient-centered outcome. METHODS: Medicare beneficiaries who entered AL communities in 2018 were identified. The main outcome is resident home time in the year following AL admission, calculated as the percentage of time spent at home (i.e., not in institutional care setting) per day being alive. Additional outcomes are the percentage of time spent in emergency room, inpatient hospital, nursing home, and inpatient hospice. AL online Google reviews for 2013-2017 were linked to 2018-2019 Medicare data. AL average rating score (ranging 1-5) and rating status (no-rating, low-rating, and high-rating) were generated using Google reviews. Linear regression models and propensity score weighting were used to examine the association between online reviews and outcomes. The study sample included 59,831 residents in 12,143 ALs. RESULTS: Residents were predominately older (average 81.2 years), non-Hispanic White (90.4%), and female (62.9%), with 17% being dually eligible for Medicare and Medicaid. From 2013 to 2017, ALs received an average rating of 4.1 on Google, with a standard deviation of 1.1. Each one-unit increase in the AL's average online rating was associated with an increase in residents' risk-adjusted home time by 0.33 percentage points (p < 0.001). Compared with residents in ALs without ratings, residents in high-rated ALs (average rating ≥4.4) had a 0.64 pp (p < 0.001) increase in home time. CONCLUSIONS: Higher online rating scores were positively associated with residents' home time, while the absence of ratings was associated with reduced home time. Our results suggest that online reviews may be a quality signal with respect to home time.

RESUMO

BACKGROUND: Antipsychotic use is a safety concern among older patients in home health care (HHC), particularly for those with Alzheimer's disease and related dementias (ADRD). The objective of this study was to examine the prevalence and predictors of antipsychotic use among older adults with and without ADRD who received HHC, and the association of antipsychotic use with outcomes among patients living with ADRD. METHODS: In this secondary analysis of adults ≥65 years receiving care from an HHC agency in New York in 2019 (N = 6684), we used data from the Outcome and Assessment Information Set, Medicare HHC claims, and home medication review results in the electronic HHC records during a 60-day HHC episode. ADRD was identified by diagnostic codes. Functional outcome was the change in the composite activities of daily living (ADL) score from HHC admission to HHC discharge (measured in 5833 patients), where a positive score means improvement and a negative score means decline. Data were analyzed using logistic (predictors) and linear regression (association with outcome) analyses. RESULTS: The point prevalence of antipsychotic use was 17.2% and 6.6% among patients with and without ADRD, respectively. Among patients living with ADRD, predictors of antipsychotic use included having greater ADL limitations (odds ratio [OR] = 1.30, p = 0.01), taking more medications (OR = 1.04, p = 0.02), having behavioral and psychological symptoms (OR = 5.26, p = 0.002), and living alone (OR = 0.52, p = 0.06). Among patients living with ADRD, antipsychotic use was associated with having less ADL improvement at HHC discharge (ß = -0.70, p < 0.001). CONCLUSIONS: HHC patients living with ADRD were more likely to use antipsychotics and to experience worse functional outcomes when using antipsychotics. Antipsychotics should be systematically reviewed and, if contraindicated or unnecessary, deprescribed. Efforts are needed to improve HHC patients' access to nonpharmacological interventions and to provide education for caregivers regarding behavioral approaches to manage symptoms in ADRD.
