Heterogeneity in the Health and Functional Capacity of Adults Aged 85+ as Risk for Mortality.

OBJECTIVES: To examine whether older adults aged 85+, with different health and functional capacities, cluster in different ways and to demonstrate whether individuals within particular clusters report differential mortality risk. DESIGN: Retrospective cohort study. SETTING: The Dynamic Analyses to Optimize Aging (DYNOPTA) project is a harmonization project of nine Australian longitudinal surveys of health and well-being in adults aged 50+ between 1991 and 2006. PARTICIPANTS: Participants were 685 older adults (female = 52%) living in the community and aged 85 to 103 at baseline who were followed until death or December 31, 2006, for survivors. MEASUREMENT: Latent class analysis (LCA) analyzed self-reported information on physical health, mental health, and functional capacity to define homogeneous classes based on probable cognitive impairment and depression status, medical conditions, and number of activities of daily living and instrumental activities of daily living. RESULTS: LCA discriminated four classes reflecting two main survival patterns. Two classes reported half the median survival days; differences between these classes were related to high vs moderate depression and extent of functional limitations. Two classes reported better survival; differences between these classes were related to functional limitations, but both had low proportions with depression and dementia. The classes with shorter survival were associated with substantively higher rates of depression and dementia. CONCLUSION: Higher rates of baseline depression and dementia were unique characteristics of those individuals in the clusters that reported shorter survival. However, a substantial proportion of very old adults experience good mental health with better survival outcomes. J Am Geriatr Soc 67:1036-1042, 2019.

Health status, health behaviours and anxiety symptoms of older male caregivers: Findings from the Concord Health and Ageing in Men Project.

OBJECTIVE: To explore differences between older male caregivers and non-caregivers on health status, health behaviours and well-being, including symptoms of anxiety. METHODS: Data were collected through self-completed questionnaires and face-to-face interviews with 1705 community living men aged ≥70 in the Concord Health and Ageing in Men Project. RESULTS: Eleven per cent of older men were caregivers, of whom 81.7% were looking after their wives or partners. Older male caregivers did not have worse physical health or more depressive symptoms than non-caregivers, but being a caregiver was associated with increased likelihood of reporting anxiety symptoms (OR: 2.32, 95% CI: 1.39-3.87). Caregivers had similar levels and frequencies of leisure activities but did more housework activities than non-caregivers. CONCLUSION: Higher anxiety levels were the main adverse health condition in older male caregivers. Strategies to assist minimising anxiety for caregivers should be a target of interventions.

Living well with chronic disease for those older adults living in the community.

BACKGROUND: Definitions of successful aging that incorporate dimensions of physical capacity and medical conditions are limited owing to the normative nature of experiencing medical conditions with age. We examine the capacity for older adults living in the community to live well with or without chronic disease as they age. METHOD: Participants (n = 1,001) were from the Melbourne Longitudinal Studies on Healthy Ageing (MELSHA) study who were aged 65+ years at baseline, were living in the community and followed for 16 years. RESULTS: Aging was associated with not living well (OR = 1.21; p < 0.001) and having a chronic disease (OR = 1.09; p < 0.001). There was increasing proportion of older adults not living well with chronic disease as they aged. Those not living well were at a substantial risk of death with (OR = 3.63; p < 0.001) or without (OR = 3.59; p < 0.001) chronic disease. DISCUSSION: The defining normative experience for older adults is that they are more likely to have a chronic disease and importantly not be living well with chronic disease as they age. However, it was the state of not living well that reflected the most substantial vulnerability for mortality, not chronic disease.

Cluster Randomized Controlled Trial of An Aged Care Specific Leadership and Management Program to Improve Work Environment, Staff Turnover, and Care Quality.

OBJECTIVE: To evaluate the effectiveness of a leadership and management program in aged care. DESIGN: Double-blind cluster randomized controlled trial. SETTING: Twelve residential and community-aged care sites in Australia. PARTICIPANTS: All care staff employed for 6 months or longer at the aged care sites were invited to participate in the surveys at 3 time points: baseline (time 1), 9 months from baseline (time 2), and 9 months after completion of time 2 (time 3) from 2011 to 2013. At each time point, at least 500 care staff completed a survey. At baseline (N = 503) the largest age group was 45 to 54 years (37%), and the majority of care staff were born in Australia (70%), spoke English (94%), and had at least completed secondary education (57%). INTERVENTION: A 12-month Clinical Leadership in Aged Care (CLiAC) program for middle managers, which aimed to further develop their leadership and management skills in creating positive workplace relationships and in enabling person-centered, evidence-based care. MAIN OUTCOME MEASURES: The primary outcomes were care staff ratings of the work environment, care quality and safety, and staff turnover rates. Secondary outcomes were care staff's intention to leave their employer and profession, workplace stress, job satisfaction, and cost-effectiveness of implementing the program. Absenteeism was excluded due to difficulty in obtaining reliable data. Managers' self-rated knowledge and skills in leadership and management are not included in this article, which focuses on care staff perceptions only. RESULTS: At 6 months after its completion, the CLiAC program was effective in improving care staff's perception of management support [mean difference 0.61, 95% confidence interval (CI) 0.04-1.18; P = .04]. Compared with the control sites, care staff at the intervention sites perceived their managers' leadership styles as more transformational (mean difference 0.30, 95% CI 0.09-0.51; P = .005), transactional (mean difference 0.22, 95% CI 0.05-0.39; P = .01), and less passive avoidant (mean difference 0.30, 95% CI 0.07-0.52; P = .01); and were rated higher on the overall leadership outcomes (mean difference 0.35, 95% CI 0.13-0.56; P = .001) as well as individual manager outcomes: extra effort (P = .004), effectiveness (P = .001), and satisfaction (P = .01). There was no evidence that CLiAC was effective in reducing staff turnover, or improving patient care quality and safety. CONCLUSIONS: While the CLiAC leadership program had direct impact on the primary process outcomes (management support, leadership actions, behaviors, and effects), this was insufficient to change the systems required to support care service quality and client safety. Nevertheless, the findings send a strong message that leadership and management skills in aged care managers can be nurtured and used to change leadership behaviors at a reasonable cost.

Subjective social support in older male Italian-born immigrants in Australia.

This paper describes differences in subjective social support between older male Italian-born immigrants in Australia and their Australian-born counterparts. Data came from 335 Italian-born and 849 Australian-born men aged 70 years and over who participated in the baseline phase of the Concord Health and Ageing in Men Project (CHAMP) in inner suburban Sydney, Australia. Social support was measured using the shortened (11 item) version of the Duke Social Support Index (DSSI). This index measures both social interactions and expressive social support. Logistic regression was used to examine differences in subjective social support between the two groups of men after controlling for other related factors. Italian-born men were about twice as likely to report low subjective social support compared to Australian-born men (unadjusted odds ratio (OR) = 1.8, p = 0.0002). This difference remained after adjustment for sociodemographic, socioeconomic, social network and health factors (adjusted OR = 2.1, p = 0.0007). Italian-born men were more likely to report that they had no non-family members in the local area to rely on. However, lack of non-family supports did not remain significantly associated with perceived social support after adjustment for social interactions and depressive symptoms. Italian-born men were more likely to report low subjective support despite the presence of several protective factors such as a greater number of local family supports and a high rate of home ownership.

Self-reported medication side effects in an older cohort living independently in the community--the Melbourne Longitudinal Study on Healthy Ageing (MELSHA): cross-sectional analysis of prevalence and risk factors.

BACKGROUND: Medication side effects are an important cause of morbidity, mortality and costs in older people. The aim of our study was to examine prevalence and risk factors for self-reported medication side effects in an older cohort living independently in the community. METHODS: The Melbourne Longitudinal Study on Healthy Ageing (MELSHA), collected information on those aged 65 years or older living independently in the community and commenced in 1994. Data on medication side effects was collected from the baseline cohort (n = 1000) in face-to-face baseline interviews in 1994 and analysed as cross-sectional data. Risk factors examined were: socio-demographics, health status and medical conditions; medication use and health service factors. Analysis included univariate logistic regression to estimate unadjusted risk and multivariate logistic regression analysis to assess confounding and estimate adjusted risk. RESULTS: Self-reported medication side effects were reported by approximately 6.7% (67/1000) of the entire baseline MELSHA cohort, and by 8.5% (65/761) of those on medication. Identified risk factors were increased education level, co-morbidities and health service factors including recency of visiting the pharmacist, attending younger doctors, and their doctor's awareness of their medications. The greatest increase in risk for medication side effects was associated with liver problems and their doctor's awareness of their medications. Aging and gender were not risk factors. CONCLUSION: Prevalence of self-reported medication side effects was comparable with that reported in adults attending General Practices in a primary care setting in Australia. The prevalence and identified risk factors provide further insight and opportunity to develop strategies to address the problem of medication side effects in older people living independently in the community setting.

Home and community care services: a major opportunity for preventive health care.

BACKGROUND: In Australia, the Home and Community Care (HACC) program provides services in the community to frail elderly living at home and their carers. Surprisingly little is known about the health of people who use these services. In this study we sought to describe health-related factors associated with use of HACC services, and to identify potential opportunities for targeting preventive services to those at high risk. METHODS: We obtained questionnaire data from the 45 and Up Study for 103,041 men and women aged 45 years and over, sampled from the general population of New South Wales, Australia in 2006-2007, and linked this with administrative data about HACC service use. We compared the characteristics of HACC clients and non-clients according to a range of variables from the 45 and Up Study questionnaire, and estimated crude and adjusted relative risks for HACC use with generalized linear models. RESULTS: 4,978 (4.8%) participants used HACC services in the year prior to completing the questionnaire. Increasing age, female sex, lower pre-tax household income, not having a partner, not being in paid work, Indigenous background and living in a regional or remote location were strongly associated with HACC use. Overseas-born people and those speaking languages other than English at home were significantly less likely to use HACC services. People who were underweight, obese, sedentary, who reported falling in the past year, who were current smokers, or who ate little fruit or vegetables were significantly more likely to use HACC services. HACC service use increased with decreasing levels of physical functioning, higher levels of psychological distress, and poorer self-ratings of health, eyesight and memory. HACC clients were more likely to report chronic health conditions, in particular diabetes, stroke, Parkinson's disease, anxiety and depression, cancer, heart attack or angina, blood clotting problems, asthma and osteoarthritis. CONCLUSIONS: HACC clients have high rates of modifiable lifestyle risk factors and health conditions that are amenable to primary and secondary prevention, presenting the potential for implementing preventive health care programs in the HACC service setting.

Widowhood and other demographic associations of pain in independent older people.

OBJECTIVES: To determine if psychosocial factors, as suggested by the demographic variables of widowhood and living alone, are associated with pain, particularly severe pain, in a representative sample of independent older people. DESIGN: One thousand older people (65+) randomly selected from independent residents living in a major city were surveyed about their health status (Health Status of Older People Study). Demographic characteristics, including age, gender, education, income, living alone, widowhood, and childlessness, were analyzed by logistic regression for their association with pain report of differing severity. Path analysis was used to confirm the association with pain severity and further define the role of mood disturbance in mediating this relationship. RESULTS: The prevalence of any pain report for the preceding 12 months was 56.3%. This was reduced when using more restrictive criteria, such that moderate-to-severe pain "at worst" and "at present" was found in 48.7% and 4.1% of the sample, respectively. After adjusting for type 1 error rate, the status of living alone was primarily associated with moderate-to-severe pain at worst, and being a widow(er) was associated with moderate-to-severe pain at present. The latter association had an estimated odds ratio greater than 3 and was characterized by more recent bereavement. Using path analysis, the model that severe pain was secondary to mood disturbance of widowhood, particularly recent bereavement, was tested and confirmed. The model explained 17% of the variance of pain severity in widow(er)s. CONCLUSION: The mood disturbance related to spousal bereavement aggravates pain in older people. This lends support to the biopsychosocial model of pain.
