Pathways linking health literacy, health beliefs, and cognition to medication adherence in older adults with asthma.

BACKGROUND: Limited health literacy is associated with low adherence to asthma controller medications among older adults. OBJECTIVE: We sought to describe the causal pathway linking health literacy to medication adherence by modeling asthma illness and medication beliefs as mediators. METHODS: We recruited adults aged 60 years and older with asthma from hospital and community practices in New York, New York, and Chicago, Illinois. We measured health literacy and medication adherence using the Short Test of Functional Health Literacy in Adults and the Medication Adherence Rating Scale, respectively. We used validated instruments to assess asthma illness and medication beliefs. We assessed cognition using a cognitive battery. Using structural equation modeling, we modeled illness and medication beliefs as mediators of the relationship between health literacy and adherence while controlling for cognition. RESULTS: Our study included 433 patients with a mean age of 67 ± 6.8 years. The sample had 84% women, 31% non-Hispanic blacks, and 39% Hispanics. The 36% of patients with limited health literacy were more likely to have misconceptions about asthma (P < .001) and asthma medications (P < .001). Health literacy had a direct effect (ß = 0.089; P < .001) as well as an indirect effect on adherence mediated by medications concerns (ß = 0.033; P = .002). Neither medication necessity (ß = 0.044; P = .138) nor illness beliefs (ß = 0.007; P = .143) demonstrated a mediational role between health literacy and adherence. CONCLUSIONS: Interventions designed to improve asthma controller medication adherence in older adults may be enhanced by addressing concerns about medications in addition to using communication strategies appropriate for populations with limited health literacy and cognitive impairments.

Adverse drug events and medication problems in "Hospital at Home" patients.

"Hospital at Home(HaH)" programs provide an alternative to traditional hospitalization. However, the incidence of adverse drug events in these programs is unknown. This study describes adverse drug events and potential adverse drug events in a new HaH program. We examined the charts of the first 50 patients admitted. We found 45 potential adverse drug events and 14 adverse drug events from admission to 30 days after HaH discharge. None of the adverse drug events were severe. Some events, like problems with medication administration, may be unique to the hospital at home setting. Monitoring for adverse drug events is feasible and important for hospital at home programs.

Brain γ-aminobutyric acid (GABA) detection in vivo with the J-editing (1) H MRS technique: a comprehensive methodological evaluation of sensitivity enhancement, macromolecule contamination and test-retest reliability.

Abnormalities in brain γ-aminobutyric acid (GABA) have been implicated in various neuropsychiatric and neurological disorders. However, in vivo GABA detection by (1) H MRS presents significant challenges arising from the low brain concentration, overlap by much stronger resonances and contamination by mobile macromolecule (MM) signals. This study addresses these impediments to reliable brain GABA detection with the J-editing difference technique on a 3-T MR system in healthy human subjects by: (i) assessing the sensitivity gains attainable with an eight-channel phased-array head coil; (ii) determining the magnitude and anatomic variation of the contamination of GABA by MM; and (iii) estimating the test-retest reliability of the measurement of GABA with this method. Sensitivity gains and test-retest reliability were examined in the dorsolateral prefrontal cortex (DLPFC), whereas MM levels were compared across three cortical regions: DLPFC, the medial prefrontal cortex (MPFC) and the occipital cortex (OCC). A three-fold higher GABA detection sensitivity was attained with the eight-channel head coil compared with the standard single-channel head coil in DLPFC. Despite significant anatomical variation in GABA + MM and MM across the three brain regions (p < 0.05), the contribution of MM to GABA + MM was relatively stable across the three voxels, ranging from 41% to 49%, a non-significant regional variation (p = 0.58). The test-retest reliability of GABA measurement, expressed as either the ratio to voxel tissue water (W) or to total creatine, was found to be very high for both the single-channel coil and the eight-channel phased-array coil. For the eight-channel coil, for example, Pearson's correlation coefficient of test vs. retest for GABA/W was 0.98 (R(2) = 0.96, p = 0.0007), the percentage coefficient of variation (CV) was 1.25% and the intraclass correlation coefficient (ICC) was 0.98. Similar reliability was also found for the co-edited resonance of combined glutamate and glutamine (Glx) for both coils. Copyright © 2016 John Wiley & Sons, Ltd.

Home but still engaged: participation in social activities among the homebound.

PURPOSE: Participation in social and community activities that require leaving one's home is important to older adults; however, many older adults have difficulty or are unable to leave their dwellings, and little is known from national samples about issues related to remaining active outside the home or the barriers faced by these older adults. DESIGN AND METHODS: We used the National Health and Aging Trends Study, a nationally representative study of older adults (n = 7197), to understand the following: (1) the importance that homebound and semi-homebound adults place on involvement in social or community activities, (2) their current level of involvement, and (3) reported barriers to participation. RESULTS: Despite the heavy burden of functional limitations, depression, pain, and falls, homebound adults reported that activities outside the home were important to them ranging from 25.2 % (attend clubs) to 70.0 % (visit family). Similarly, semi-homebound older adults had a strong interest in such participation, including visiting friends and family (81.8 %), attending religious services (72.6 %), and going out for enjoyment (72.5 %). Many homebound adults reported health (42.9-64.1 % depending on the activity) and transportation (12.2-18.2 %) as barriers to participation. Semi-homebound adults also identified health (23.8-41.0 %) and transportation (6.5-10.2 %) as participation barriers. IMPLICATIONS: This information can be useful in designing community programs that will foster meaningful social and community engagement for older adults, which may improve their quality of life.

Polypharmacy in the Aging Patient: A Review of Glycemic Control in Older Adults With Type 2 Diabetes.

IMPORTANCE: There is substantial uncertainty about optimal glycemic control in older adults with type 2 diabetes mellitus. OBSERVATIONS: Four large randomized clinical trials (RCTs), ranging in size from 1791 to 11,440 patients, provide the majority of the evidence used to guide diabetes therapy. Most RCTs of intensive vs standard glycemic control excluded adults older than 80 years, used surrogate end points to evaluate microvascular outcomes and provided limited data on which subgroups are most likely to benefit or be harmed by specific therapies. Available data from randomized clinical trials suggest that intensive glycemic control does not reduce major macrovascular events in older adults for at least 10 years. Furthermore, intensive glycemic control does not lead to improved patient-centered microvascular outcomes for at least 8 years. Data from randomized clinical trials consistently suggest that intensive glycemic control immediately increases the risk of severe hypoglycemia 1.5- to 3-fold. Based on these data and observational studies, for the majority of adults older than 65 years, the harms associated with a hemoglobin A1c (HbA1c) target lower than 7.5% or higher than 9% are likely to outweigh the benefits. However, the optimal target depends on patient factors, medications used to reach the target, life expectancy, and patient preferences about treatment. If only medications with low treatment burden and hypoglycemia risk (such as metformin) are required, a lower HbA1c target may be appropriate. If patients strongly prefer to avoid injections or frequent fingerstick monitoring, a higher HbA1c target that obviates the need for insulin may be appropriate. CONCLUSIONS AND RELEVANCE: High-quality evidence about glycemic treatment in older adults is lacking. Optimal decisions need to be made collaboratively with patients, incorporating the likelihood of benefits and harms and patient preferences about treatment and treatment burden. For the majority of older adults, an HbA1c target between 7.5% and 9% will maximize benefits and minimize harms.

Internal Medicine Residents' Perceptions of Team-Based Care and its Educational Value in the Continuity Clinic: A Qualitative Study.

BACKGROUND: In order to teach residents how to work in interprofessional teams, educators in graduate medical education are implementing team-based care models in resident continuity clinics. However, little is known about the impact of interprofessional teams on residents' education in the ambulatory setting. OBJECTIVE: To identify factors affecting residents' experience of team-based care within continuity clinics and the impact of these teams on residents' education. DESIGN: This was a qualitative study of focus groups with internal medicine residents. PARTICIPANTS: Seventy-seven internal medicine residents at the University of California San Francisco at three continuity clinic sites participated in the study. APPROACH: Qualitative interviews were audiotaped and transcribed. The authors used a general inductive approach with sensitizing concepts in four frames (structural, human resources, political and symbolic) to develop codes and identify themes. KEY RESULTS: Residents believed that team-based care improves continuity and quality of care. Factors in four frames affected their ability to achieve these goals. Structural factors included communication through the electronic medical record, consistent schedules and regular team meetings. Human resources factors included the presence of stable teams and clear roles. Political and symbolic factors negatively impacted team-based care, and included low staffing ratios and a culture of ultimate resident responsibility, respectively. Regardless of the presence of these factors or resident perceptions of their teams, residents did not see the practice of interprofessional team-based care as intrinsically educational. CONCLUSIONS: Residents' experiences practicing team-based care are influenced by many principles described in the interprofessional teamwork literature, including understanding team members' roles, good communication and sufficient staffing. However, these attributes are not correlated with residents' perceptions of the educational value of team-based care. Including residents in interprofessional teams in their clinic may not be sufficient to teach residents how team-based care can enhance their overall learning and future practice.

Enhanced Recovery Stem-Cell Transplantation: Multidisciplinary Efforts to Improve Outcomes in Older Adults Undergoing Hematopoietic Stem-Cell Transplant.

PURPOSE: Older adults have unique risk factors for poor outcomes after hematopoietic stem-cell transplant (HSCT). We sought to determine the impact of our multidisciplinary supportive care program, Enhanced Recovery after stem-cell transplant (ER-SCT), on survival outcomes in patients age 65 years and older who underwent HSCT. PATIENTS AND METHODS: In this retrospective study, clinicodemographic data, nonrelapse mortality (NRM), overall survival (OS), and relapse were compared between 64 patients age 65 years and older who underwent allogeneic stem-cell transplant during ER-SCT program's first year, October 2017 through September 2018, and 140 historical controls age 65 years and older who underwent allogeneic HSCT, January 2015 through September 2017. RESULTS: In the ER-SCT cohort, 41% (26 of 64) of patients were women, and the median (range) age was 68 (65-74) years; in the control cohort, 38% (53 of 140) of patients were women, and the median (range) age was 67 (65-79) years. Hematopoietic cell transplant comorbidity index and donor type/cell source were similar between cohorts. The ER-SCT cohort had a lower 1-year NRM rate (13% v 26%, P = .03) and higher 1-year OS rate (74% v 53%, P = .007). Relapse rate did not differ significantly between cohorts. In multivariate analyses, ER-SCT was associated with improved 1-year NRM (hazard ratio, 0.4; 95% CI, 0.2 to 0.9; P = .02) and improved 1-year OS (hazard ratio, 0.5; 95% CI, 0.3 to 0.9; P = .03). CONCLUSION: A multidisciplinary supportive care program may improve NRM and OS in older patients undergoing allogeneic HSCT. Randomized studies are warranted to confirm this benefit and explore which program components most contribute to the improved outcomes.

An update on cancer-related fatigue in older adults: A narrative review.

Up to 70% of older adults report fatigue after a cancer diagnosis. For many of these patients, cancer-related fatigue (CRF) persists for years after cancer treatment and is associated with significant disability. Despite this, little has been written on the diagnosis and management of CRF in older adults. To address this gap, we performed a narrative review of the literature on CRF in older adults and used literature from the general population when evidence was lacking to provide guidance to clinical providers on how to tailor care to this population. We recommend evidence-based options for evaluating CRF and address their limitations in the assessment of older adults. We also provide guidance and a treatment algorithm on evaluating CRF using the Comprehensive Geriatrics Assessment. Lastly, we present evidence for the use of non-pharmacologic and pharmacologic therapies in the management of CRF in older adults.

Feasibility and Implementation of a Multimodal Supportive Care Program to Improve Outcomes in Older Patients Undergoing Allogeneic Stem Cell Transplantation.

Increasingly, patients age ≥65 years are undergoing allogeneic hematopoietic stem cell transplantation (allo-SCT). Although age alone is a well-documented predictor of overall survival (OS) and nonrelapse mortality (NRM), growing evidence suggests that poor functional status and frailty associated with aging may have roles as well. Our goal in the present study was to identify and improve these and other aging-related maladies by developing a multimodal supportive care program for older allo-SCT recipients. We designed and implemented a multimodal supportive care program, Enhanced Recovery in Stem Cell Transplant (ER-SCT), for patients age ≥65 years undergoing allo-SCT. The ER-SCT program consists of evaluation and critical interventions by key health care providers from multiple disciplines starting before hospital admission for transplantation and extending through 100 days post-allo-SCT. We determined the feasibility of implementing this program in a large stem cell transplantation center. After 1 year of ongoing process improvements, multiple evaluations, and enrollment, we found that a dedicated weekly clinic was necessary to coordinate care and evaluate patients early. We successfully enrolled 57 of 64 eligible patients (89%) in the first year. Our data show that a multimodal supportive care program to enhance recovery for older patients undergoing allo-SCT is feasible. © 2021 American Society for Transplantation and Cellular Therapy.

Hospital at Home-Plus: A Platform of Facility-Based Care.

OBJECTIVES: To describe the evolution of a hospital at home (HaH) program to a HaH with a 30-day posthospitalization transition period (HaH-Plus) and results of a retrospective review of cases. DESIGN: After launching HaH-Plus, we used the same interdisciplinary clinical team to provide acute home-based care for a broader range of home-based acute-level services than originally conceived in the Hospital at Home model. These included a palliative care unit at home (PCUaH), an observation unit at home (OUaH), a post-acute care rehabilitation at home (RaH), and a program for the hospital averse - those patients needing to be in the hospital but who refuse. SETTING: Urban health system. PARTICIPANTS: Individuals 18 years or older residing in specified catchment area with Medicare fee-for-service or accepted Medicare/Medicaid Advantage plans requiring facility-based care. INTERVENTION: Provision of facility-based acute-level care at home to 685 participants. MEASUREMENTS: Length of stay, readmission, and mortality. RESULTS: HaH-Plus cared for 685 individuals. The PCUaH had the oldest participants (mean age 87), and all groups were predominantly female and dually eligible for Medicare and Medicaid. Diagnoses and length of stay were similar in all groups except that those in RaH had a larger group of diagnoses, than those accepted in to HaH-Plus and those in OUaH had a shorter stay. Rate of readmission was highest for RaH (19%). Mortality during the active treatment episode was highest for PCUaH and hospital averse as compared to HaH-Plus, OUaH and RaH. CONCLUSION: Providing a broader range of facility-based care in the home has significant advantages for patients and increases the scalability of HaH. Developing a spectrum of services was possible by leveraging a robust, 24-hour HaH team. Community- and home-based care could become a greater part of the U.S. healthcare system if a platform of HaH services along with advances in technology and payment models were developed.

Association of a Bundled Hospital-at-Home and 30-Day Postacute Transitional Care Program With Clinical Outcomes and Patient Experiences.

Importance: Hospital-at-home (HaH) care provides acute hospital-level care in a patient's home as a substitute for traditional inpatient care. In September 2017, the Physician-Focused Payment Model Technical Advisory Committee recommended implementation of an alternative payment model for a new model of HaH that bundles the acute episode with 30 days of postacute transitional care. Objective: To report outcomes of this new payment model for HaH care. Design, Setting, and Participants: Case-control study of HaH care patients with a concurrent control group of hospital inpatients recruited from emergency departments (EDs) and residences in New York City from November 18, 2014, to August 31, 2017. HaH patients were 18 years or older with fee-for-service Medicare and acute medical illness requiring inpatient-level care. Control patients met HaH eligibility but refused participation or were seen in the ED when a HaH admission could not be initiated. Exposures: HaH care or inpatient care. Main Outcomes and Measures: Primary outcomes were acute period length of stay (LOS), all-cause 30-day hospital readmissions and ED visits, admissions to skilled nursing facilities (SNFs), referral to a certified home health care agency, and patient experiences with care. Analyses accounted for nonrandom selection using inverse probability weighting. Results: Among the 507 patients enrolled (mean [SD] age, 74.6 [15.7] years; 68.6% women), data were available on all patients 30 days postdischarge. HaH patients (n = 295) were older than controls (n = 212) and more likely to have a preacute functional impairment. HaH patients had shorter LOS (3.2 days vs 5.5 days; difference, -2.3 days; 95% CI, -1.8 to -2.7 days; weighted P < .001); lower rates of readmissions (8.6% [25] vs 15.6% [32]; difference, -7.0%; 95% CI, -12.9% to -1.1%; weighted P < .001), ED revisits (5.8% [17] vs 11.7% [24]; difference, -5.9%; 95% CI, -11.0% to -0.7%; weighted P < .001), and SNF admissions (1.7% [5] vs 10.4% [22]; difference, -8.7%; 95% CI, -13.0% to -4.3%; weighted P < .001); and were also more likely to rate their hospital care highly (68.8% [119] vs 45.3% [67]; difference, 23.5%; 95% CI, 12.9% to 34.1%; weighted P < .001). There were no differences in referrals to certified home health agencies. Conclusions and Relevance: HaH care bundled with a 30-day postacute transitional care episode was associated with better patient outcomes and ratings of care compared with inpatient hospitalization. This model warrants consideration for addition to Medicare's current portfolio of shared savings programs.

Two-Year Mortality in Homebound Older Adults: An Analysis of the National Health and Aging Trends Study.

OBJECTIVES: To determine the association between homebound status and mortality. DESIGN: Cross-sectional. SETTING: Annual, in-person interviews. PARTICIPANTS: A nationally representative sample of community-dwelling, Medicare beneficiaries aged 65 and older enrolled in the National Health and Aging Trends Study between 2011 and 2013 (N = 6,400). MEASUREMENTS: Two-year mortality and prevalence of homebound status in the year before death are described using three categories of homebound status: homebound (never or rarely left home in the last month), semihomebound (left home with assistance, needed help or had difficulty), and nonhomebound (left home without help or difficulty). RESULTS: In unadjusted analyses, 2-year mortality was 40.3% in homebound participants, 21.3% in those who were semihomebound and 5.8% in those who were nonhomebound. Homebound status was associated with greater 2-year mortality, adjusted for sociodemographic characteristics, comorbidities, and functional status (hazard ratio = 2.08; 95% confidence interval = 1.63-2.65, P < .001). Half of older community-dwelling Medicare beneficiaries were homebound in the year before death. CONCLUSION: Homebound status is associated with greater risk of death independent of functional impairment and comorbidities. To improve outcomes for homebound older adults and the many older adults who will become homebound in the last year of life, providers and policymakers need to extend healthcare services from hospitals and clinics to the homes of vulnerable individuals.

Identifying Sociodemographic Characteristics Associated With Burden Among Caregivers of the Urban Homebound: The Importance of Racial and Relationship Differences.

Limited research has explored whether the burden associated with caring for homebound patients varies across racial groups or by relationship status. We examined these variations for this vulnerable population. Patients self-identified informal caregivers and caregiver burden/depression were assessed using the Zarit Caregiver Burden Scale and the Center for Epidemiologic Studies-Depression scale (CES-D). Forty-nine informal caregivers completed the interview. Mean age was 58 (SD = 14), 78% were female, 37% Black, 35% Hispanic, and 46% had completed high school. Over 60% of caregivers had moderate or severe caregiver burden and 30% had significant depression. White caregivers had greater burden than Black and Hispanic caregivers (p = .02). Mean caregiver burden was higher among spouse/partner caregivers, versus those who identified as children or other family or friends (p = .004). Additional research is needed to better understand the experience of racial and ethnic minorities and spouses in providing informal care to homebound adults.

Predictors of Place of Death of Individuals in a Home-Based Primary and Palliative Care Program.

OBJECTIVES: To investigate factors associated with place of death of individuals in the Mount Sinai Visiting Doctors Program (MSVD). DESIGN: A retrospective chart review was performed of all MSVD participants who died in 2012 to assess predictors of place of death in the last month of life. SETTING: MSVD, a home-based primary and palliative care program in New York. PARTICIPANTS: MSVD participants who were discharged from the program because of death between January 2012 and December 2012 and died at home, in inpatient hospice, or in the hospital (N = 183). MEASUREMENTS: Electronic medical records were reviewed to collect information on demographic characteristics, physician visits, and end-of-life conversations. RESULTS: Of 183 participants, 103 (56%) died at home, approximately twice the national average; 28 (15%) died in inpatient hospice; and 52 (28%) died in the hospital. Bivariate analyses showed that participants who were white, aged 90 and older, non-Medicaid, or had a recorded preference for place of death were more likely to die outside the hospital. Diagnoses and living situation were not significantly associated with place of death. Multivariate logistic regression analysis showed no statistical association between place of death and home visits in the last month of life (odds ratio = 1.21, 95% confidence interval = 0.52-2.77). CONCLUSION: Home-based primary and palliative care results in a high likelihood of nonhospital death, although certain demographic characteristics are strong predictors of death in the hospital. For MSVD participants, home visits in the last month of life were not associated with death outside the hospital.

"My older clients fall through every crack in the system": geriatrics knowledge of legal professionals.

With the number of older adult arrestees and prisoners increasing rapidly, legal professionals increasingly provide front-line identification and response to age-related health conditions (including cognitive and physical impairments) that may affect legal outcomes, such as the ability to participate in one's defense or stay safe in jail. The goals of this study were to assess the ability of legal professionals to recognize and respond to age-related conditions that could affect legal outcomes and to identify recommendations to address important knowledge gaps. This was a mixed quantitative-qualitative study. Legal professionals (N = 72) in the criminal justice system were surveyed to describe their demographic characteristics, expertise, and prior aging-related training and to inform the qualitative interview guide. Those surveyed included attorneys (district attorneys (25%), public defenders and legal advocates (58%)), judges (6%), and court-affiliated social workers (11%). In-depth qualitative interviews were then conducted with a subset of 10 legal professionals who worked with older adults at least weekly. Results from the surveys and interviews revealed knowledge deficits in four important areas: age-related health, identification of cognitive impairment, assessment of safety risk, and optimization of services upon release from jail. Four recommendations to close these gaps emerged: educate legal professionals about age-related health, train professionals to identify cognitive and sensory impairment, develop checklists to identify those at risk of poor health or safety, and improve knowledge of and access to transitional services for older adults. These findings suggest that geriatrics knowledge gaps of legal professionals exist that may contribute to adverse medical or legal outcomes for older adults involved in the criminal justice system and that partnerships between healthcare and legal professionals are needed to address these challenges.
