    ABSTRACT: The Hospital Elder Life Program (HELP) can prevent delirium, a common condition in older hospitalized adults associated with substantial morbidity, mortality, and healthcare costs. In 2011, HELP transitioned to a web-based dissemination model to provide accessible resources, including implementation materials; information for healthcare professionals, patients, and families; and a searchable reference database. It was hypothesized that, although intended to assist sites to establish HELP, the resources that the HELP website offer might have broader applications. An e-mail was sent to all HELP website registrants from September 10, 2012, to March 15, 2013, requesting participation in an online survey to examine uses of the resources on the website and to evaluate knowledge diffusion related to these resources. Of 102 responding sites, 73 (72%) completed the survey. Thirty-nine (53%) had implemented and maintained an active HELP model. Twenty-six (35%) sites had used the HELP website resources to plan for implementation of the HELP model and 35 (50%) sites to implement and support the program during and after launch. Sites also used the resources for the development of non-HELP delirium prevention programs and guidelines. Forty-five sites (61%) used the website resources for educational purposes, targeting healthcare professionals, patients, families, or volunteers. The results demonstrated that HELP resources were used for implementation of HELP and other delirium prevention programs and were also disseminated broadly in innovative educational efforts across the professional and lay communities. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

    ABSTRACT: Home-based primary care (HBPC) is an effective model of noninstitutional long-term care developed in the Department of Veterans Affairs (VA) to provide ongoing care to homebound persons. Significant rural populations of American Indians have limited access to services designed for frail older adults. Fourteen Veterans Affairs Medical Centers (VAMCs) initiated efforts to expand access to HBPC in concert with local tribes and Indian Health Service (IHS) facilities. This study characterizes the resulting emerging models of HBPC and co-management. Using an observational design, key respondent telephone interviews (n = 37) were conducted with stakeholders representing the 14 VAMCs to describe these HBPC programs, and HBPC models were evaluated in relation to VAMC organizational culture as revealed on the annual VA All Employee Survey. Twelve VAMCs independently developed HBPC expansion programs for American Indian veterans, and six different program models were implemented. Two models were unique to collaborations between VAMCs and tribes; in these collaborations, the tribes retained primary care responsibilities. VAMC used the other four models for delivery of care in remote rural areas to all veteran populations, American Indians and non-Indians alike. Strategies to improve access by reducing geographic barriers occur in all models. Comparing mean VAMC organizational culture ratings, as defined in the Competing Values Framework, revealed significant group differences for one of these six models. Findings from this study illustrate the flexibility of the HBPC program and opportunities for co-management and expansion of healthcare access for American Indians and non-Indians, particularly in rural areas. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

    ABSTRACT: Advances in bacterial deoxyribonucleic acid sequencing allow for characterization of the human commensal bacterial community (microbiota) and its corresponding genome (microbiome). Surveys of healthy adults reveal that a signature composite of bacteria characterizes each unique body habitat (e.g., gut, skin, oral cavity, vagina). A myriad of clinical changes, including a basal proinflammatory state (inflamm-aging), that directly interface with the microbiota of older adults and enhance susceptibility to disease accompany aging. Studies in older adults demonstrate that the gut microbiota correlates with diet, location of residence (e.g., community dwelling, long-term care settings), and basal level of inflammation. Links exist between the microbiota and a variety of clinical problems plaguing older adults, including physical frailty, Clostridium difficile colitis, vulvovaginal atrophy, colorectal carcinoma, and atherosclerotic disease. Manipulation of the microbiota and microbiome of older adults holds promise as an innovative strategy to influence the development of comorbidities associated with aging. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

    ABSTRACT: To determine whether acute hospitalization is associated with a change in potentially inappropriate medication (PIM) use and whether use varies across geographic region. Observational. Continental United States. Medicare beneficiaries aged 65 and older hospitalized for acute myocardial infarction (AMI) during 2007-08. Potentially inappropriate medication use was defined according to the High-Risk Medications in Elderly Adults quality indicator from the Healthcare Effectiveness Data and Information Set. Prevalence of outpatient PIM use was determined at admission and discharge and then used to identify medications discontinued during hospitalization and incident medications started during this period. Of 124,051 older adults hospitalized for AMI, 9,607 (7.7%) were outpatient PIM users at admission, which increased to 8.6% at discharge (P < .001). Admission PIM rates varied according to geographic region, as did the effect of hospitalization. Admission PIM use was lowest in the northeast and remained unchanged during hospitalization (5.1-5.1%, P = .95). In contrast, admission PIM use was highest in the south and increased significantly during hospitalization (9.9-11.4%, P < .001). PIM use also increased from the long-term perspective, with 6-month period prevalence rates of 22.6% before admission and 24.6% after discharge (P < .001). Despite intervention studies demonstrating up to 80% reduction in PIM use during acute hospitalization, a significant increase in PIM use was observed in a naturalistic setting in Medicare beneficiaries with AMI. Further research is needed to develop an approach to minimizing PIM use in the inpatient setting that is cost-effective and suitable for widespread implementation. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

    ABSTRACT: To use a simple measure of activities of daily living, wounds, and indwelling devices (urinary catheter, feeding tube) to predict prevalent, new, and intermittent multidrug-resistant organism (MDRO) acquisition in nursing home (NH) residents. Secondary analysis, prospective cohort study. Southeast Michigan NHs (n = 15). NH residents (N = 111, mean age 81) with two or more monthly visits (729 total). Monthly microbiological surveillance for MDROs from multiple anatomic sites from enrollment until discharge or 1 year. The Arling scale, previously developed as a measure of NH residents' need (time-intensity) for nursing resources, was used to predict prevalent and time to new or intermittent acquisition (months) of methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and antibiotic-resistant gram-negative bacteria (R-GNB) colonization using multiple-failure accelerated time-factor survival analysis, controlling for comorbidity, hospitalization, and antibiotic use in the prior month. One-fifth of participants had a wound, and one-third had a device. There were 60 acquisitions of MRSA, 56 of R-GNB, and 15 of VRE. Expected time to acquisition was less than 1 year for MRSA (median 6.7 months) and R-GNB (median 4.5 months) and more than 1 year for VRE (median 40 months). Arling score was associated with earlier new MRSA and VRE acquisition. A resident with only mild functional impairment and no device or wound would be expected to acquire MRSA in 20 months, versus 5 months for someone needing the most-intense nursing contact. MDRO acquisition is common in community NHs. Need for nursing care predicts new MDRO acquisition in NHs, suggesting potential mechanisms for MDRO acquisition and strategies for future interventions for high-risk individuals (e.g., enhanced barrier precautions).

    ABSTRACT: To determine whether poor asthma control is associated with cognitive impairment in a cohort of older, inner-city adults with asthma. Prospective observational cohort study. Outpatient practices in New York City and Chicago. Individuals aged 60 and older with a physician diagnosis of asthma and without chronic obstructive pulmonary disease or a smoking history of 10 pack-years or more (N = 452). Cognitive assessments that included processing speed (pattern comparison, Trail-Making Test Part A), executive function (Trail-Making Test Part B), attention and working memory (letter number sequencing), immediate and delayed recall (Wechsler Memory Scale Story A), word fluency (animal naming), and global cognitive function (Mini-Mental State Examination) were administered. Asthma control was measured using the Asthma Control Questionnaire (ACQ) and airway obstruction using spirometry as the predicted forced expiratory volume at 1 second (FEV1 ) of less than 70%. Cognitive measures were modeled in linear and logistic regression models controlling for age, race, education, English proficiency, and income. Participants had a mean age of 68; 41% had poor asthma control according to the ACQ, and 35% had FEV1 of less than 70%. Poor asthma control and FEV1 less than 70% were significantly associated with all measures of cognitive function in univariate analyses, although these associations lost their statistical significance after adjusting for age, education, English proficiency, and other covariates. The same pattern was observed when the outcomes were below-normal performance on the cognitive measures based on normative data. Poor asthma control and airway obstruction are not associated with poor performance on various measures of cognitive function in older adults with asthma. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

    ABSTRACT: Objectives To examine the association between sleep complaints, use of sleep-promoting medications, and persistent severe fatigue (PSF).DesignAnalysis of data from the National Health Aging Trends Study.SettingContiguous United States.ParticipantsA representative sample of Medicare beneficiaries aged 65 and older.MeasurementsDifficulty initiating sleep, difficulty staying asleep, use of sleep-promoting medications, demographic characteristics, presence of pain, use of pain medications, depression, chronic medical disease, physical activity level, and Short Physical Performance Battery score measured at baseline. The outcome of interest was PSF (fatigue that limits daily activities reported at baseline and 12-month follow-up).ResultsOf 8,245 participants at baseline, 7,075 completed 12-month follow-up; 31% reported severe fatigue at baseline and 31% at follow-up, and 19% reported PSF. In a logistic regression model, difficulty staying asleep some nights (odds ratio (OR) = 1.32, 95% confidence interval (CI) = 1.08–1.60) and most nights or every night (OR = 1.40, 95% CI = 1.09–1.79) and use of sleep-promoting medications most nights or every night (OR = 1.35, 95% CI = 1.08–1.67) independently predicted PSF.Conclusion The results indicate greater risk of PSF in older adults with difficulty staying asleep and those who use sleep-promoting medications. These findings underscore the significance of sleep problems and present potential targets for interventional studies that aim to improve fatigue in older adults.

    ABSTRACT: Objectives To determine safety and tolerability of lowering blood pressure in older adults with lacunar stroke.DesignCohort study.SettingThe Secondary Prevention of Small Subcortical Strokes (SPS3) Trial, which compared the efficacy of two systolic blood pressure (SBP) targets (<130 mmHg and 130–149 mmHg) for secondary stroke prevention.ParticipantsOf 3,020 SPS3 participants, 494 aged 75 and older at baseline were used in these analyses.MeasurementsRates of side effects related to lowering SBP and clinical outcomes, including stroke recurrence and vascular death, were examined.ResultsOlder participants achieved SBP levels similar to those of younger participants (mean SBP of 125 mmHg and 137 mmHg in lower and higher SBP target groups, respectively). At least once during the approximately 3.5 years of follow-up, 21% reported dizziness, and 15% reported lightheadedness when standing; the only significant difference between the younger and older groups was unsteadiness when standing (23% vs 32% respectively, P < .001). There was no difference according to treatment group. In younger adults, recurrent stroke was less likely in the lower than the higher SBP group (hazard ratio (HR) = 0.77, 95% confidence interval (CI) = 0.59–1.01) but not in older participants (HR = 1.01, 95% CI = 0.59–1.73), although the interaction was not significant (P = .39). The lower SBP target was associated with a significant reduction in vascular death in older participants (HR = 0.42, 95% CI = 0.18–0.98), with a significant interaction between age and SBP group (P = .049).Conclusion Except for unsteadiness when standing, there was no difference according to age in individuals with lacunar stroke with respect to side effects potentially related to lowering blood pressure. Although the lower SBP target was not associated with lower likelihood of recurrent stroke, these exploratory analyses suggested a possible benefit related to vascular death.

    ABSTRACT: Objective To test the hypothesis that mild cognitive impairment (MCI) is associated with poorer financial and healthcare decision-making.DesignCommunity-based epidemiological cohort study.SettingCommunities throughout northeastern Illinois.ParticipantsOlder persons without dementia from the Rush Memory and Aging Project (N = 730).MeasurementsAll participants underwent a detailed clinical evaluation and decision-making assessment using a measure that closely approximates materials used in real-world financial and healthcare settings. This allowed for measurement of total decision-making and financial and healthcare decision-making. Regression models were used to examine whether MCI was associated with a lower level of decision-making. In subsequent analyses, the relationship between specific cognitive systems (episodic memory, semantic memory, working memory, perceptual speed, visuospatial ability) and decision-making was explored in participants with MCI.ResultsMCI was associated with lower total, financial, and healthcare decision-making scores after accounting for the effects of age, education, and sex. The effect of MCI on total decision-making was equivalent to the effect of more than 10 additional years of age. Additional models showed that, when considering multiple cognitive systems, perceptual speed accounted for the most variance in decision-making in participants with MCI.Conclusion Persons with MCI may have poorer financial and healthcare decision-making in real-world situations, and perceptual speed may be an important contributor to poorer decision-making in persons with MCI.

    ABSTRACT: The purpose of the study was to examine the effects of participation in the Living Legends program upon health science students' image of older adults and interest in working with older people. A multisite quasi-experimental control group design with a connected qualitative component was used. Program sites included three Naturally Occurring Retirement Communities (NORCs) and one senior center. Health science students (n = 43) from two universities and two community colleges and community-dwelling seniors (n = 39) participated in the program. A baseline questionnaire was used to ascertain demographic characteristics and prior type and amount of contact with older adults. The Image of Aging Scale and Likert-style questions to measure interest in working with older adults were the primary outcome measures. Written responses to program experiences were also collected. Analysis of covariance was used to compare changes in Image of Aging subscale scores from pre- to posttest. Mean change in positive image of older adults subscale scores was 4.6 (SD = 4.4) for the intervention group and -0.6 (SD = 4.8) for the control group. The difference between groups was significant (F = 22.0, P < .001), and the effect size was large (Cohen's d = 1.07). Nine of the 22 students in the intervention group had a greater interest in working with seniors after the program. Qualitative themes that emerged included a positive and beneficial experience, life lessons, seeing the person beyond the visible, power of the written word, and shared lives. Living Legends is an effective program to enhance positive images of older adults in future healthcare professionals and may have a positive impact on some students with regard to interest in working with older adults. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

    ABSTRACT: To compare quality of end-of-life (EOL) care indicators and family evaluation of care in community living centers (CLCs) with that of EOL care in acute, intensive, and hospice and palliative care units. Retrospective chart review and survey with next of kin of recently deceased inpatients. Inpatient Veterans Affairs (VA) Medical Centers (N = 145), including 132 CLCs, across the United States. The chart review included all individuals who died in VA inpatient units (n = 57,397). Family survey results included data for 33,497 veterans. Indicators of optimal EOL care: palliative consultation in the last 90 days of life, contact with a chaplain, family contact with a chaplain, and emotional support given to family after death. The main outcome was a single Bereaved Family Survey item in which respondents provided a global evaluation of quality of EOL care (excellent to very good, good, fair to poor). Family evaluations of overall EOL care and quality of EOL care indicators for veterans who died in CLCs were better than those of veterans dying in acute or intensive care units but worse than those dying in hospice or palliative care units. Care in CLCs can be enhanced through the integration of palliative care practices. Future research should identify critical elements of enhancing EOL care in nursing homes. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

    ABSTRACT: Objectives To determine whether adjustment for prognostic indices specifically developed for nursing home (NH) populations affect the magnitude of previously observed associations between mortality and conventional and atypical antipsychotics.DesignCohort study.SettingA merged data set of Medicaid, Medicare, Minimum Data Set (MDS), Online Survey Certification and Reporting system, and National Death Index for 2001 to 2005.ParticipantsDual-eligible individuals aged 65 and older who initiated antipsychotic treatment in a NH (N = 75,445).MeasurementsThree mortality risk scores (Mortality Risk Index Score, Revised MDS Mortality Risk Index, Advanced Dementia Prognostic Tool) were derived for each participant using baseline MDS data, and their performance was assessed using c-statistics and goodness-of-fit tests. The effect of adjusting for these indices in addition to propensity scores (PSs) on the association between antipsychotic medication and mortality was evaluated using Cox models with and without adjustment for risk scores.ResultsEach risk score showed moderate discrimination for 6-month mortality, with c-statistics ranging from 0.61 to 0.63. There was no evidence of lack of fit. Imbalances in risk scores between conventional and atypical antipsychotic users, suggesting potential confounding, were much lower within PS deciles than the imbalances in the full cohort. Accounting for each score in the Cox model did not change the relative risk estimates: 2.24 with PS-only adjustment versus 2.20, 2.20, and 2.22 after further adjustment for the three risk scores.Conclusion Although causality cannot be proven based on nonrandomized studies, this study adds to the body of evidence rejecting explanations other than causality for the greater mortality risk associated with conventional antipsychotics than with atypical antipsychotics.
