Multi-stakeholder validation of entrustable professional activities for a family medicine care of the elderly residency program: a focus group study.

Entrustable Professional Activities (EPAs) have become widely used within Competency-Based Medical Education (CBME) for the training and evaluation of residents. Little is known about the effectiveness of incorporating multiple stakeholder groups in the validation of EPAs. Here, we seek to validate an EPA framework developed for the University of Manitoba Care of the Elderly Enhanced Skills program using online focus groups consisting of five stakeholder groups. Participants were recruited to take part in one of five online focus groups, one for each stakeholder group (physician faculty, residents, non-physician healthcare professionals, administrators/managers, and patients). Each group met one time for 90 minutes over ZOOM®. The themes arising from stakeholder feedback suggest that successful EPAs must neither be too specific nor too expansive in scope, clearly delineate appropriate means of evaluation, and indicate specific clinical settings in which each EPA should be evaluated. Cross-cutting themes included requiring trainees to collaborate with other professionals when it would optimize patient care, and preparing trainees to advocate for their patients' health (Advocacy). The present study demonstrates that multi-stakeholder analysis yields diverse feedback that can help make EPAs more clear, easier to use in evaluation, and more socially accountable.

Multimorbidity in Canadians living in the community: Results from the Canadian Longitudinal Study of Aging.

OBJECTIVE: To determine the mean number of chronic diseases in Canadians aged 45 to 85 years who are living in the community, and to characterize the association of multimorbidity with age, sex, and social position. DESIGN: An analysis of data from the Canadian Longitudinal Study on Aging. The number of self-reported chronic diseases was summed, and then the mean number of chronic health problems was standardized to the 2011 Canadian population. Analyses were conducted stratified on sex, age, individual income, household income, and education level. SETTING: Canada. PARTICIPANTS: A total of 21 241 community-living Canadians aged 45 to 85 years. MAIN OUTCOME MEASURES: Overall, 31 chronic diseases (self-reported from a list) were considered, as were risk factors that were not mental health conditions or acute in nature. Age, sex, education, and household and individual incomes were also self-reported. RESULTS: Multimorbidity was common, and the mean number of chronic illnesses was 3.1. Women had a higher number of chronic illnesses than men. Those with lower income and less education had more chronic conditions. The number of chronic conditions was strongly associated with age. The mean number of conditions was 2.1 in those aged 45 to 54; 2.9 in those 55 to 64; 3.8 in those aged 65 to 74, and 4.8 in those aged 75 and older (P < .05, ANOVA [analysis of variance]). CONCLUSION: Multimorbidity is common in the Canadian population and is strongly related to age.

Life satisfaction in adults in rural and urban regions of Canada - the Canadian Longitudinal Study on Aging.

INTRODUCTION: Understanding rural-urban differences, and understanding levels of life satisfaction in rural populations, is important in planning social and healthcare services for rural populations. The objectives of this study were to determine patterns of life satisfaction in Canadian rural populations aged 45-85 years, to determine rural-urban differences in life satisfaction across a rural-urban continuum after accounting for potential confounding factors and to determine if related social and health factors of life satisfaction differ in rural and urban populations. METHODS: A secondary analysis was conducted using data from an ongoing population-based cohort study, the Canadian Longitudinal Study on Aging. A cross-sectional sample from the baseline wave of the tracking cohort was used, which was intended to be as generalizable as possible to the Canadian population. Four geographic areas were compared on a rural-urban continuum: rural, mixed (indicating some rural, but could also include some peri-urban areas), peri-urban, and urban. Life satisfaction was measured using the Satisfaction with Life Scale and dichotomized as satisfied versus dissatisfied. Other factors considered were province of residence, age, sex, education, marital status, living arrangement, household income, and chronic conditions. These factors were self-reported. Bivariate analyses using χ2 tests were conducted for categorical variables. Logistic regression models were constructed with the outcome of life satisfaction, after which a series of models were constructed, adjusting for province of residence, age, and sex, for sociodemographic factors, and for health-related factors. To report on differences in the factors associated with life satisfaction in the different areas, logistic regression models were constructed, including main effects for the variable of interest, for the variable rurality, and for the interaction term between these two variables. RESULTS: Individuals living in rural areas were more satisfied with life than their urban counterparts (odds ratio (OR)=1.23; 95% confidence interval (CI): 1.13-1.35), even after accounting for the effect of confounding sociodemographic and health-related factors (OR=1.32, 95%CI: 1.19-1.45). Those living in mixed (OR=1.30, 95%CI: 1.14-1.49) and peri-urban (OR=1.21, 95%CI: 1.07-1.36) areas also reported being more satisfied than those living in urban areas. In addition, a positive association was found between life satisfaction and age, as well as between life satisfaction and being female. A strong graded association was noted between income and life satisfaction. Most chronic conditions were associated with lower life satisfaction. Finally, no major interaction was noted between rurality and each of the previously mentioned different factors associated with life satisfaction. CONCLUSION: Rural-urban differences in life satisfaction were found, with higher levels of life satisfaction in rural populations compared to urban populations. Preventing and treating common chronic illness, and also reducing inequalities in income, may prove useful to improving life satisfaction in both rural and urban areas. Studies of life satisfaction should consider rurality as a potential confounding factor in analyses of life satisfaction within and across societies.

Migraine and the risk of all-cause dementia, Alzheimer's disease, and vascular dementia: A prospective cohort study in community-dwelling older adults.

OBJECTIVES: Dementia is the most common neurological disease in older adults; headaches, including migraines, are the most common neurological disorder across all ages. The objective of this study was to explore the relationship between migraines and dementia, including Alzheimer's disease (AD) and vascular dementia (VaD). METHODS: Analyses were based on 679 community-dwelling participants 65+ years from the Manitoba Study of Health and Aging, a population-based, prospective cohort study. Participants screened as cognitively intact at baseline had complete data on migraine history and all covariates at baseline and were assessed for cognitive outcomes (all-cause dementia, AD, and VaD) 5 years later. The association of exposure (lifetime history of migraines), confounding (age, gender, education, and depression), and intervening variables (hypertension, myocardial infarction, other heart conditions, stroke, and diabetes) with all-cause dementia and dementia subtypes (AD and VaD) was assessed using multiple logistic regression models. RESULTS: A history of migraines was significantly associated with both all-cause dementia (odds ratio [OR]=2.97; 95% confidence interval [CI]=1.25-6.61) and AD (OR=4.22; 95% CI=1.59-10.42), even after adjustment for confounding and intervening variables. Migraines were not significantly associated with VaD either before (OR=1.83; 95% CI=0.39-8.52) or after (OR=1.52; 95% CI=0.20-7.23) such adjustment. CONCLUSIONS: Migraines were a significant risk factor for AD and all-cause dementia. Despite the vascular mechanisms involved in migraine physiology, migraines were not significantly associated with VaD in this study. Recognition of the long-term detrimental consequences of migraines for AD and dementia has implications for migraine management, as well as for our understanding of AD etiology.

The prevalence of multimorbidity and associations with lifestyle factors among middle-aged Canadians: an analysis of Canadian Longitudinal Study on Aging data.

BACKGROUND: Multimorbidity can be defined as the presence of more than one chronic condition in an individual. Research on multimorbidity has predominantly focused on older adults and few studies have examined multimorbidity in middle-aged people. The objectives of this study were to: 1) examine the prevalence of multimorbidity among middle-aged Canadians; and 2) examine the association between lifestyle factors (smoking, alcohol intake, physical activity) and multimorbidity in this age group. METHODS: In this analysis of the Canadian Longitudinal Study on Aging (CLSA) baseline data, we extracted data from 29,841 participants aged 45-64 years from a database of 51,338 people aged 45-85 years. Self-reported data on 27 chronic physical health conditions were used to derive different multimorbidity definitions. We estimated the prevalence of 3+ to 5+ chronic physical health conditions in different subgroups for descriptive purposes. Multivariable logistic regression analyses were performed to determine the association between socio-demographic and lifestyle factors, and multimorbidity using a 3+ multimorbidity case definition. RESULT: We found that 39.6% (99% CI 38.4-40.7) of participants had three or more chronic conditions with a mean number of chronic condition of 2.41 (99% CI 2.37-2.46). The prevalence of multimorbidity increased with age from 29.7% in the 45-49-year-old age group to 52% in individuals aged 60-64 years. The prevalence of 4+ and 5+ chronic conditions was 24.5 and 14.2% respectively. Analyses indicated that female sex and low income were associated with higher odds of multimorbidity, whereas daily or weekly alcohol intake were associated with lower odds of multimorbidity. Exercise was not associated with multimorbidity. Results were similar when analyses were conducted separately for women and men. CONCLUSIONS: Multimorbidity is not limited to older adults, but is a common phenomenon among middle-aged people. Longitudinal research is needed to better understand the temporal relationship between lifestyle factors and multimorbidity.

Multimorbidity predicts functional decline in community-dwelling older adults: Prospective cohort study.

OBJECTIVE: To determine if multimorbidity is associated with functional status, and to assess if multimorbidity predicts declining functional status over a 5-year time frame, after accounting for baseline functional status and other potential confounding factors. DESIGN: Analysis of an existing population-based cohort study. SETTING: Manitoba. PARTICIPANTS: Community-dwelling adults aged 65 and older. MAIN OUTCOME MEASURES: Age, sex, education, and the Mini-Mental State Examination (MMSE) and Center for Epidemiological Studies Depression Scale (CES-D) scores were recorded for each patient. Multimorbidity was measured using a simple tally of self-reported diseases. Function was measured using the Older Americans Resources and Services scale in 1991 to 1992 and again 5 years later. Good or excellent level of function was compared with level of disability (mild or moderate or higher). Cross-sectional and prospective analyses were conducted. RESULTS: In a cross-sectional analysis, multimorbidity predicted disability. The unadjusted odds ratio (OR) (95% CI) for disability was 1.45 (1.39 to 1.52) for each additional chronic illness. In models adjusting for age, sex, education, and MMSE and CES-D scores, the adjusted OR (95% CI) was 1.35 (1.29 to 1.42) for each additional chronic illness. Multimorbidity also predicted disability 5 years later. The unadjusted OR (95% CI) was 1.31 (1.24 to 1.38). In models adjusting for age, sex, education, and MMSE and CES-D scores in addition to baseline functional status, the adjusted OR (95% CI) was 1.15 (1.09 to 1.24). CONCLUSION: Multimorbidity predicts disability in cross-sectional and prospective analyses.

The cumulative effect of frailty and cognition on mortality - results of a prospective cohort study.

BACKGROUND: Both physical frailty and cognitive impairment predict death, but the joint effect of these two factors is uncertain. The objectives are to determine if the Mini-mental state examination (MMSE) and the Frailty Index (FI) predict death over a five-year interval after accounting for the effect of the other; and if there is an interaction in this effect. METHODS: An analysis of an existing prospective cohort study of 1,751 community living older adults followed over a five-year time frame. Age, gender, and education were self-reported. The predictor variables were the FI - a measure of frailty based on the "Accumulation of Deficits" model of frailty; and the MMSE. Cox proportional hazards models were constructed for the outcome of time to death. RESULTS: The unadjusted Hazard Ratio (HR) (95% CI) for mortality was 2.17 (1.69, 2.80) for those who were only cognitively impaired, 2.02 (1.53, 2.68) for those who were only frail, and 3.57 (2.75, 4.62) for those who were both frail and cognitively impaired with the reference group of those who were neither frail nor cognitively impaired. Adjusted for age, gender, and education, the HR (95% CI) was 1.49 (1.13. 1.95) for those who were only cognitively impaired, 1.81 (1.35, 2.41) for those who were only frail, and 2.28 (1.69, 3.09) for those who were both frail and cognitively impaired. CONCLUSIONS: Both frailty and cognitive impairment are predictors of mortality and the effect is cumulative. There was no interaction in this effect.

General life satisfaction predicts dementia in community living older adults: a prospective cohort study.

BACKGROUND: Low life satisfaction predicts adverse outcomes, and may predict dementia. The objectives were: (1) to determine if life satisfaction predicts dementia over a five year period in those with normal cognition at baseline; and (2) to determine if different aspects of life satisfaction differentially predict dementia. METHODS: Secondary analysis of an existing population-based cohort study with initial assessment in 1991 and follow-up five years later. Initially, 1,751 adults age 65+ living in the community were sampled from a representative sampling frame. Of these, 1,024 were alive and had complete data at time 2, of whom 96 were diagnosed with dementia. Life satisfaction was measured using the Terrible-Delightful scale, which measures overall life satisfaction on a 7-point scale, as well as various aspects of life satisfaction (e.g. friendships, finances, etc.) Dementia was diagnosed by clinical examination using DSM-IIIR criteria. Logistic regression models were constructed for the outcome of dementia at time 2, and adjusted for age, gender, education, and comorbidities. RESULTS: Overall life satisfaction predicted dementia five years later, at time 2. The unadjusted Odds Ratio (OR; 95% confidence interval) for dementia at time 2 was 0.72 (0.55, 0.95) per point. The adjusted OR for dementia was 0.70 (0.51, 0.96). No individual item on the life satisfaction scale predicted dementia. However, the competing risk of mortality was very high for some items. CONCLUSION: A global single-item measure of life satisfaction predicts dementia over a five year period in older adults without cognitive impairment.

Comparison of ActiGraph GT3X+ and StepWatch Step Count Accuracy in Geriatric Rehabilitation Patients.

Activity monitors may not accurately detect steps in hospitalized older adults who walk slowly. We compared ActiGraph GT3X+ step counts (hip and ankle locations, default and low frequency extension [LFE] analyses) to the StepWatch monitor (ankle) during a hallway walk in 38 geriatric rehabilitation patients (83.2 ± 7.1 years of age, 0.4 ± 0.2 m/s gait speed). Absolute percent error values were low (<3%) and did not differ for the StepWatch and the GT3X+ (ankle, LFE); however, error values were high (19-97%) when the GT3X+ was worn at the hip and/ or analyzed with the default filter. Although these finding suggest the GT3X+ (ankle, LFE) functions as well as the StepWatch in detecting steps during walking in older adults with slow gait speeds, further research is needed to determine whether the GT3X+ is also able to disregard other body movements (e.g., fidgeting) that occur when full day monitoring is utilized.

Cognition, even in the normal range, predicts disability: cross-sectional and prospective analyses of a population-based sample.

OBJECTIVE: To determine if the modified mini-mental state examination (3MS) predicts functional status and if any effect on function is observed within the normal range of cognition. DESIGN: Cohort study. SETTING: Community-dwelling older adults in the Canadian province of Manitoba sampled in 1991 and followed in 1996. PARTICIPANTS: Baseline sample of 1751 adults aged 65+ from a representative registry. Five years later, 1028 participants remained in the community and had no missing data. MEASUREMENTS: The 3MS, age, gender, education, living arrangements, self-rated health, and depressive symptoms were self-reported. Functional status was assessed using the Older Americans Resource Survey, which was dichotomized into no/mild disability versus moderate/severe disability. RESULTS: Baseline 3MS score predicted baseline functional status. This effect was a gradient across the entire 3MS score, extending into the normal range with no apparent threshold. In logistic regression models, the unadjusted odds ratio (OR, 95% confidence interval) for the association of 3MS score with disability was 0.94 (0.93, 0.95); the adjusted OR was 0.96 (0.95, 0.98) in models including age, gender, education, and other covariates. Baseline 3MS score also predicted functional status 5 years later: The unadjusted OR for disability was 0.94 (0.92, 0.95); the adjusted OR was 0.97 (0.95, 0.99). Again, the risk of functional impairment at time 2 was a gradient effect, extending into the normal range of baseline 3MS score. CONCLUSIONS: The 3MS predicts functional decline, and this effect is a gradient effect. These results support the hypothesis that cognition is a continuum in risk.

The role of income and occupation in the association of education with healthy aging: results from a population-based, prospective cohort study.

BACKGROUND: The beneficial effects of higher education on healthy aging are generally accepted, but the mechanisms are less well understood. Education may influence healthy aging through improved employment opportunities that enhance feelings of personal control and reduce hazardous exposures, or through higher incomes that enable individuals to access better health care or to reside in better neighbourhoods. Income and occupation have not been explored extensively as potential mediators of the effect of education on healthy aging. This study investigates the role of income and occupation in the association between education and healthy aging including potential effect modification by gender. METHODS: Logistic regression was used to explore the association of education, income (perceived income adequacy, life satisfaction with finances) and occupation (occupational prestige) with healthy aging five years later in 946 community-dwelling adults 65+ years from a population-based, prospective cohort study in Manitoba, Canada. RESULTS: Higher levels of education generally increased the likelihood of healthy aging. After adjusting for education, both income measures, but not occupation, predicted healthy aging among men; furthermore, the association between education and healthy aging was no longer significant. Income and occupation did not explain the significant association between education and healthy aging among women. CONCLUSIONS: Perceived income adequacy and life satisfaction with finances explained the beneficial effects of higher education on healthy aging among men, but not women. Identifying predictors of healthy aging and the mechanisms through which these factors exert their effects can inform strategies to maximize the likelihood of healthy aging.

Does life satisfaction predict five-year mortality in community-living older adults?

OBJECTIVES: Depression and depressive symptoms predict death, but it is less clear if more general measures of life satisfaction (LS) predict death. Our objectives were to determine: (1) if LS predicts mortality over a five-year period in community-living older adults; and (2) which aspects of LS predict death. METHOD: 1751 adults over the age of 65 who were living in the community were sampled from a representative population sampling frame in 1991/1992 and followed five years later. Age, gender, and education were self-reported. An index of multimorbidity and the Older American Resource Survey measured health and functional status, and the Terrible-Delightful Scale assessed overall LS as well as satisfaction with: health, finances, family, friends, housing, recreation, self-esteem, religion, and transportation. Cox proportional hazards models examined the influence of LS on time to death. RESULTS: 417 participants died during the five-year study period. Overall LS and all aspects of LS except finances, religion, and self-esteem predicted death in unadjusted analyses. In fully adjusted analyses, LS with health, housing, and recreation predicted death. Other aspects of LS did not predict death after accounting for functional status and multimorbidity. CONCLUSION: LS predicted death, but certain aspects of LS are more strongly associated with death. The effect of LS is complex and may be mediated or confounded by health and functional status. It is important to consider different domains of LS when considering the impact of this important emotional indicator on mortality among older adults.

Is bilingualism associated with a lower risk of dementia in community-living older adults? Cross-sectional and prospective analyses.

OBJECTIVE: The aim of this study was to determine whether bilingualism is associated with dementia in cross-sectional or prospective analyses of older adults. METHODS: In 1991, 1616 community-living older adults were assessed and were followed 5 years later. Measures included age, sex, education, subjective memory loss (SML), and the modified Mini-mental State Examination (3MS). Dementia was determined by clinical examination in those who scored below the cut point on the 3MS. Language status was categorized based upon self-report into 3 groups: English as a first language (monolingual English, bilingual English) and English as a Second Language (ESL). RESULTS: The ESL category had lower education, lower 3MS scores, more SML, and were more likely to be diagnosed with cognitive impairment, no dementia at both time 1 and time 2 compared with those speaking English as a first language. There was no association between being bilingual (ESL and bilingual English vs. monolingual) and having dementia at time 1 in bivariate or multivariate analyses. In those who were cognitively intact at time 1, there was no association between being bilingual and having dementia at time 2 in bivariate or multivariate analyses. CONCLUSIONS: We did not find any association between speaking >1 language and dementia.

Multimorbidity, disability, and mortality in community-dwelling older adults.

OBJECTIVE: To describe factors associated with multimorbidity in community-dwelling older adults; to determine if a simple measure of multimorbidity predicts death over 5 years; and to assess if any effect of multimorbidity on mortality is independent of key covariates. DESIGN: Analysis of an existing population-based cohort study. Cox proportional hazards models were constructed for time to death. SETTING: Manitoba. PARTICIPANTS: A total of 1751 community-dwelling adults aged 65 and older were interviewed and followed for 5 years. MAIN OUTCOME MEASURES: Age, sex, marital status, living arrangement, education, Mini-Mental State Examination (MMSE) score, Center for Epidemiologic Studies Depression Scale score, and the Older Americans Resource and Services Multidimensional Functional Assessment Questionnaire score were recorded for each participant. Multimorbidity was defined based on a simple list of common health complaints and diseases, followed by an open-ended question about other problems. These were summed and the scores ranged from 0 to 16. Death and time of death were determined during the 5-year interval by death certificate, administrative data, or proxy report. RESULTS: Multimorbidity was more prevalent in women; older age groups; and those with lower educational levels, lower MMSE scores, more depressive symptoms, and higher levels of disability. Multimorbidity was a predictor of mortality in unadjusted models (hazard ratio 1.09, 95% CI 1.05 to 1.12). In models adjusting for age, sex, education, marital status, living arrangement, and Center for Epidemiologic Studies Depression Scale and MMSE scores, this effect persisted (hazard ratio 1.04, 95% CI 1.00 to 1.08). However, after adjusting for functional status, the effect of multimorbidity was no longer significant. CONCLUSION: Multimorbidity predicts 5-year mortality but the effect might be mediated by disability.

Multi-Stakeholder Validation of an Entrustable Professional Activities Framework for Canadian Geriatrics Residency Programs.

Background: Entrustable Professional Activities (EPAs) have become a cornerstone for an increasing number of competency-based medical education programs. Today, frameworks of EPAs are being used in most, if not all, medical specialties. These frameworks can break a discipline down to its constituting tasks, and structure the training and evaluation of residents. In 2018, The Royal College of Physicians and Surgeons of Canada created an EPA framework for Geriatric Specialty residency programs nationwide. The present study aims to evaluate this EPA framework through focus groups consisting of several stakeholder groups. Methods: Participants were recruited to be part of one of five focus groups-one for each stakeholder group of interest. The five focus groups consisted of: physician faculty, residents, allied health professionals, administrators/managers, and patients. Each focus group met once virtually over ZOOM® for no longer than 90 minutes. Meeting transcripts were iteratively coded based on emerging themes, and were compared for similarities and gaps between stakeholder perspectives. Results: Multi-stakeholder consultation yielded feedback on many specific EPAs, suggestions for new EPAs, and additional input which gave rise to four themes: (i) EPA scope, (ii) Operationalization, (iii) Interprofessional Collaboration, and (iv) Patient Advocacy. Lastly, we received their thoughts on how the framework defines Geriatrics relative to the work of Care of the Elderly physicians in Canada. Conclusions: Consulting a variety of stakeholder groups generates a robust and diverse supply of feedback that holistically augments EPA frameworks to be more practical, appropriate, socially accountable and patient-centred.

A call for caution when using network methods to study multimorbidity: an illustration using data from the Canadian Longitudinal Study on Aging.

OBJECTIVES: To examine the impact of two key choices when conducting a network analysis (clustering methods and measure of association) on the number and type of multimorbidity clusters. STUDY DESIGN AND SETTING: Using cross-sectional self-reported data on 24 diseases from 30,097 community-living adults aged 45-85 from the Canadian Longitudinal Study on Aging, we conducted network analyses using 5 clustering methods and 11 association measures commonly used in multimorbidity studies. We compared the similarity among clusters using the adjusted Rand index (ARI); an ARI of 0 is equivalent to the diseases being randomly assigned to clusters, and 1 indicates perfect agreement. We compared the network analysis results to disease clusters independently identified by two clinicians. RESULTS: Results differed greatly across combinations of association measures and cluster algorithms. The number of clusters identified ranged from 1 to 24, with a low similarity of conditions within clusters. Compared to clinician-derived clusters, ARIs ranged from -0.02 to 0.24, indicating little similarity. CONCLUSION: These analyses demonstrate the need for a systematic evaluation of the performance of network analysis methods on binary clustered data like diseases. Moreover, in individual older adults, diseases may not cluster predictably, highlighting the need for a personalized approach to their care.

Impact of age, comorbidity, and polypharmacy on receipt of systemic therapy in advanced cancers: A retrospective population-based study.

INTRODUCTION: Cancer incidence, comorbidity, and polypharmacy increase with age, but the interplay between these factors on receipt of systemic therapy (ST) in advanced cancer has rarely been studied. MATERIALS AND METHODS: A retrospective cohort study was conducted including patients aged ≥18 years diagnosed from 2004 to 2015 with multiple myeloma (MM) (all stages), lung cancer (stage IV), and stage III-IV non-Hodgkin's lymphoma (NHL), breast, colorectal (CRC), prostate, or ovarian cancer in Manitoba, Canada. Clinical and administrative health data were used to determine demographic and cancer characteristics, treatment history, comorbidity (Charlson Comorbidity Index [CCI] and Resource Utilization Band [RUB]), and polypharmacy (≥6 medications). Multivariable logistic regression was used to evaluate variable associations with receipt of ST and interaction with age. RESULTS: In total, 17,228 patients were diagnosed with advanced cancer. Ages were distributed as follows: 7% <50 years, 16% 50-59 years, 26% 60-69, 26% 70-79, 24% ≥80 years. ST was administered to 50% of patients. Increased age, polypharmacy, and comorbidity each independently decreased the likelihood of receiving ST. Significant interaction effects were found between age at diagnosis with stage of cancer and cancer type. Differences in probability of ST by cancer stage converged as age increased. In multivariable analysis, adjusting for covariates, patients with MM had the highest odds and lung cancer the lowest odds to receive ST. The impact of comorbidity and polypharmacy did not differ meaningfully with increasing age. DISCUSSION: Increased age, polypharmacy, and comorbidity were each independently associated with decreased receipt of ST in people with advanced cancers. The impact of comorbidity and polypharmacy did not differ meaningfully with increasing age, while age meaningfully interacted with stage and cancer type.

Does self-rated health predict dementia?

OBJECTIVES: 1. To determine if Self-Rated Health (SRH) predicts dementia over a five period in cognitively intact older adults, and in older adults with Cognitive Impairment, No Dementia (CIND); and 2. To determine if different methods of eliciting SRH (age-referenced (AR) versus unreferenced) yield similar results. DESIGN: Prospective cohort. POPULATION: 1468 cognitively intact adults and 94 older adults with CIND aged 65+ living in the community, followed over five years. MEASURES: Age, gender, education, subjective memory loss, depressive symptoms, functional status, cognition, SRH and AR-SRH were all measured; dementia was diagnosed on clinical examination. Those with abnormal cognition not meeting criteria for dementia were diagnosed with CIND. RESULTS: In those who were cognitively intact at time 1, and had good SRH: 69.4% were intact; 6.0% had CIND; 6.9% had dementia, and 17.7% had died at time 2, while in those with poor SRH: 44.9% were intact, 11.1% had CIND, 9.1% had dementia, and 34.8% had died (p<0.001, chi-square test). In multinomial regression models SRH predicted dementia and death. In those with CIND at time 1 and good SRH: 2.3% were intact: 18.6% had CIND; 34.9% had dementia and 44.2% had died at time 2, while in those with poor SRH: 4.8% were intact, 31.0% had CIND, 19.0% had dementia, and 43.6% had died (p=0.30, chi-square test). In multinomial regression models, this was not significant. AR-SRH analyses were similar. CONCLUSIONS: In cognitively intact older adults SRH predicts dementia. In older adults with CIND, SRH does not predict dementia.

Depressive symptoms and frailty.

BACKGROUND: Frailty and depressive symptoms are common issues facing older adults and may be associated. OBJECTIVES: To determine if: (i) depressive symptoms are associated with frailty; (ii) there is a gradient in this effect across the range of depressive symptoms; and (iii) the association between depressive symptoms and frailty is specific to particular types of depressive symptoms (positive affect, negative affect, somatic complaints, and interpersonal relations). METHOD: Secondary analysis of an existing population-based study was conducted. POPULATION: In 1991, 1751 community-living adults aged 65+ years were interviewed. MEASURES: Depressive symptoms were measured using the Center for Epidemiologic Studies-Depression (CES-D) scale. Frailty was graded from 0 (no frailty) to 3 (moderate/severe frailty). Age, gender, education, marital status, self-rated health, and the number of comorbid conditions were self-reported. ANALYSES: Logistic regression models were constructed with the outcome of no frailty/urinary incontinence only versus frailty. RESULTS: Depressive symptoms were strongly associated with frailty, and there was a gradient effect across the entire range of the CES-D scale. The odds ratio and 95% confidence interval was 1.08 (1.06, 1.09) per point of the CES-D in unadjusted models. After potential confounding factors were adjusted, the adjusted odds ratio (95% confidence interval) was 1.03 (1.01, 1.05). Positive affect, negative affect, and somatic complaints were all associated with frailty, whereas interpersonal relations were not associated with frailty. CONCLUSIONS: Depressive symptoms are associated with frailty. Clinicians should consider assessing frail older adults for the presence of depression.
