Codesign of health technology interventions to support best-practice perioperative care and surgical waitlist management.

OBJECTIVES: This project aimed to determine where health technology can support best-practice perioperative care for patients waiting for surgery. METHODS: An exploratory codesign process used personas and journey mapping in three interprofessional workshops to identify key challenges in perioperative care across four health districts in Sydney, Australia. Through participatory methodology, the research inquiry directly involved perioperative clinicians. In three facilitated workshops, clinician and patient participants codesigned potential digital interventions to support perioperative pathways. Workshop output was coded and thematically analysed, using design principles. RESULTS: Codesign workshops, involving 51 participants, were conducted October to November 2022. Participants designed seven patient personas, with consumer representatives confirming acceptability and diversity. Interprofessional team members and consumers mapped key clinical moments, feelings and barriers for each persona during a hypothetical perioperative journey. Six key themes were identified: 'preventative care', 'personalised care', 'integrated communication', 'shared decision-making', 'care transitions' and 'partnership'. Twenty potential solutions were proposed, with top priorities a digital dashboard and virtual care coordination. DISCUSSION: Our findings emphasise the importance of interprofessional collaboration, patient and family engagement and supporting health technology infrastructure. Through user-based codesign, participants identified potential opportunities where health technology could improve system efficiencies and enhance care quality for patients waiting for surgical procedures. The codesign approach embedded users in the development of locally-driven, contextually oriented policies to address current perioperative service challenges, such as prolonged waiting times and care fragmentation. CONCLUSION: Health technology innovation provides opportunities to improve perioperative care and integrate clinical information. Future research will prototype priority solutions for further implementation and evaluation.

Cost-Consequence Analysis of Deprescribing to Optimize Health Outcomes for Frail Older People: A Within-Trial Analysis.

OBJECTIVES: The structured, clinically supervised withdrawal of medicines, known as deprescribing, is one strategy to address inappropriate polypharmacy. This study aimed to evaluate the costs and consequences of deprescribing in frail older people living in residential aged care facilities (RACFs) in Australia. DESIGN: A within-trial cost-consequence analysis of a deprescribing intervention-Opti-Med. The Opti-Med double-blind randomized controlled trial of deprescribing included 3 groups: blinded control, blinded intervention, and an open intervention group. SETTING AND PARTICIPANTS: Seventeen RACFs in Western Australia and New South Wales. Participants were 303 older people living in participating RACFs from March 2014 to February 2019. METHODS: Analysis was conducted from the health sector perspective. Health economic outcomes assessed include cost saved from deprescribed medicines and the incremental quality-adjusted life-years. Costs were presented in 2022 Australian dollars. RESULTS: The total cost of the Opti-Med intervention was $239.13 per participant. The costs saved through deprescribed medicines over 12 months after adjusting for mortality within the trial period was $328.90 per participant in the blinded intervention group and $164.00 per participant in the open intervention group. On average, the cost of the intervention was more than offset by the cost saved from deprescribed medicines. Extrapolating these findings to the Australian population suggests a potential net cost saving of about $1 to $16 million per annum for the health system nationally. The incremental quality-adjusted life-years were very similar across the 3 groups within the trial period. CONCLUSIONS AND IMPLICATIONS: Deprescribing for frail older people living in RACFs can be a cost-saving intervention without reducing the quality of life. Systemwide implementation of deprescribing across RACFs in Australia has the potential to improve health care delivery through the cost savings, which could be reapplied to further optimize care within RACFs.

Empirically derived dietary patterns are associated with major adverse cardiovascular events, all-cause mortality, and congestive cardiac failure in older men: The Concord Health and Ageing in Men Project.

BACKGROUND: Diet is associated with major adverse cardiovascular events (MACE). OBJECTIVE: We evaluated the associations between empirically derived dietary patterns and MACE. DESIGN: Prospective cohort study. SETTING: The Concord Health and Ageing in Men Project, Sydney, Australia. PARTICIPANTS: 539 community-dwelling older Australian men aged 75 years and older. METHODS: Men underwent dietary assessment using a validated dietitian-administered diet history questionnaire. Cox regression analyses were conducted between MACE and the three dietary patterns identified from factor analysis. Five-point MACE comprised of all-cause mortality, myocardial infarction (MI), congestive cardiac failure (CCF), coronary revascularisation, and/or ischaemic stroke. Four-point MACE included the four endpoints of MI, CCF, coronary revascularisation, and/or ischaemic stroke, and excluded all-cause mortality. RESULTS: At a median of 5.3 (IQR 4.6-6.3) years of follow-up, the incidences were: five-point MACE 31.2% (n = 168); four-point MACE excluding all-cause mortality 17.8% (n = 96); all-cause mortality 20.1% (n = 111); CCF 11.3% (n = 61); MI 3.7% (n = 20); stroke 3.2% (n = 17); and coronary revascularisation 3.1% (n = 15). In fully adjusted analyses, compared to the bottom tertile, the middle tertile of 'vegetables-legumes-seafood' dietary pattern was associated with reduced five-point MACE (HR 0.67 [95% CI: 0.45, 0.99, P = .047]), and CCF (HR 0.31 [95% CI: 0.15, 0.65, P = .002]), whilst the middle tertile of 'wholegrains-milk-other fruits' dietary pattern was associated with increased five-point MACE (HR 1.78 [95% CI: 1.17, 2.70, P = .007]), four-point MACE (HR 1.92 [95% CI: 1.12, 3.30, P = .018]), and CCF (HR 2.33 [95% CI: 1.17, 4.65, P = .016]). For the 'discretionary-starchy vegetables-processed meats' dietary pattern, a higher score was associated with increased five-point MACE (HR 1.33 [95% CI: 1.09, 1.62, P = .004]), and all-cause mortality (HR 1.63 [95% CI: 1.26, 2.12, P < .001]), and compared to the bottom tertile, the top tertile was associated with increased all-cause mortality (HR 2.26 [95% CI: 1.27, 4.00, P = .005]). CONCLUSION: Older men may benefit from consuming a 'vegetables-legumes-seafood' dietary pattern rather than 'discretionary-starchy vegetables-processed meats' and 'wholegrains-milk-other fruits' dietary patterns for the prevention of MACE.

Randomized Trial of Information for Older Women About Cessation of Breast Cancer Screening Invitations.

BACKGROUND: Older women receive no information about why Australia's breast screening program (BreastScreen) invitations cease after 74 years. We tested how providing older women with the rationale for breast screening cessation impacted informed choice (adequate knowledge; screening attitudes aligned with intention). METHODS: In a three-arm online randomized trial, eligible participants were females aged 70-74 years who had recently participated in breast screening (within 5 years), without personal breast cancer history, recruited through Qualtrics. Participants read a hypothetical scenario in which they received a BreastScreen letter reporting no abnormalities on their mammogram. They were randomized to receive the letter: (1) without any rationale for screening cessation (control); (2) with screening cessation rationale in printed-text form (e.g., downsides of screening outweigh the benefits after age 74); or (3) with screening cessation rationale presented in an animation video form. The primary outcome was informed choice about continuing/stopping breast screening beyond 74 years. RESULTS: A total of 376 participant responses were analyzed. Compared to controls (n = 122), intervention arm participants (text [n = 132] or animation [n = 122]) were more likely to make an informed choice (control 18.0%; text 32.6%, p = .010; animation 40.5%, p < .001). Intervention arm participants had more adequate knowledge (control 23.8%; text 59.8%, p < .001; animation 68.9%, p < .001), lower screening intentions (control 17.2%; text 36.4%, p < .001; animation 49.2%, p < .001), and fewer positive screening attitudes regarding screening for themselves in the animation arm, but not in the text arm (control 65.6%; text 51.5%, p = .023; animation 40.2%, p < .001). CONCLUSIONS: Providing information to older women about the rationale for breast cancer screening cessation increased informed decision-making in a hypothetical scenario. This study is an important first step in improving messaging provided by national cancer screening providers direct to older adults. Further research is needed to assess the impact of different elements of the intervention and the impact of providing this information in clinical practice, with more diverse samples.

Health-Related Quality of Life among Older Adults with Dementia Living in Vietnamese Nursing Homes.

Better understanding of the quality of life among nursing home residents with dementia is important for developing interventions. The objectives of this cross-sectional study were to examine factors associated with poor health-related quality of life in older people with dementia living in nursing homes in Hanoi, Vietnam. In-person interviews were conducted with 140 adults who were 60 years and older with dementia, and information about their quality of life was obtained using the Quality of Life in Alzheimer's Disease (QOL-AD) scale. The sociodemographic and clinical factors associated with poor health-related quality of life (lowest quartile) were assessed through the results of physical tests, interviews with nursing home staff, and review of medical records. The average age of the study sample was 78.3 years, 65% were women, and their average QOL-AD total score was 27.3 (SD = 4.4). Malnutrition, total dependence in activities of daily living, and urinary incontinence were associated with poor quality of life after controlling for multiple potentially confounding factors. Our findings show that Vietnamese nursing home residents with dementia have a moderate total quality of life score, and interventions based on comprehensive geriatric assessment remain needed to modify risk factors related to poor health-related quality of life.

The association of dietary antioxidants and the inflammatory potential of the diet with poor physical function and disability in older Australian men: the Concord Health and Ageing in Men Project.

Our objective was to evaluate the association of antioxidant intake and the inflammatory potential of the diet with functional decline in older men. A diet history questionnaire was used to collect dietary intake data from men aged ≥ 75 years (n 794) participating in the Concord Health and Aging in Men Project cohort study. Intake of vitamins A, C, E and Zn were compared with the Australian Nutrient Reference Values to determine adequacy. The Energy-adjusted Dietary Inflammatory Index (E-DIITM) was used to assess the inflammatory potential of the diet. Physical performance data were collected via handgrip strength and walking speed tests, and activities of daily living (ADL) and instrumental activities of daily living (IADL) questionnaires, at baseline and 3-year follow-up (n 616). Logistic regression analysis was used to identify associations between diet and incident poor physical function and disability. Both poor antioxidant intake and high E-DII scores at baseline were significantly associated with poor grip strength and ADL disability at 3-year follow-up. No significant associations with walking speed or IADL disability were observed. Individual micronutrient analysis revealed a significant association between the lowest two quartiles of vitamin C intake and poor grip strength. The lowest quartiles of intake for vitamins A, C, E and Zn were significantly associated with incident ADL disability. The study observed that poor antioxidant and anti-inflammatory food intake were associated with odds of developing disability and declining muscle strength in older men. Further interventional research is necessary to clarify the causality of these associations.

Cross-sectional and longitudinal associations between empirically derived dietary patterns and frailty among older men: The Concord Health and Ageing in Men Project.

BACKGROUND: Diet may be associated with frailty. OBJECTIVE: We aimed to evaluate the associations between empirically derived dietary patterns and frailty in older men. DESIGN: Prospective cohort study. SETTING: The Concord Health and Ageing in Men Project, Sydney, Australia. PARTICIPANTS: 785 community-dwelling older Australian men aged 75 years and older. METHODS: Men underwent dietary assessment using a validated dietitian-administered diet history questionnaire. Factor analysis identified three dietary patterns. Multinomial logistic regression was conducted between frailty and dietary patterns for cross-sectional analyses and longitudinal analyses over a 3-year follow-up. Frailty was defined by the Fried frailty phenotype. RESULTS: Of the 785 men, pre-frailty was prevalent in 47.1% (n = 370), and frailty in 8.3% (n = 65). In fully adjusted cross-sectional analyses, the top tertile and a higher 'vegetables-legumes-seafood' dietary pattern score were associated with reduced prevalence of frailty (OR 0.34 [95% CI: 0.12, 0.93, P = .036]) and OR 0.50 [95% CI: 0.30, 0.83, P = .007] respectively). The top tertile of the 'discretionary-starchy vegetables-processed meats' dietary pattern was also associated cross-sectionally with increased prevalence of pre-frailty (OR 1.75 [95% CI: 1.08, 2.83, P = .022]). Of the 296 robust men in fully adjusted longitudinal analyses, the incidence of pre-frailty was 52.4% (n = 155), and frailty was 5.4% (n = 16) over a 3-year follow-up. The middle tertile of the 'vegetables-legumes-seafood' dietary pattern had a non-significant trend towards reduced incident pre-frailty (OR 0.52 [95% CI: 0.27, 1.00, P = .050]). CONCLUSION: Consumption of a 'vegetables-legumes-seafood' dietary pattern appears to be less favoured by frail older men.

The effectiveness of a home-based dietetic intervention for community-dwelling older adults.

OBJECTIVES: The aim of this study was to describe the characteristics of clients receiving home-based dietetic intervention and to evaluate the effectiveness of these interventions in improving nutritional status, functional status, and quality of life in a culturally and socioeconomically diverse client group. METHODS: Participants referred to a home-based dietetic service were recruited to this prospective cohort study. Dietetic interventions were recommended at baseline and reviewed at 3-month follow-up. Assessment of nutritional, functional and quality of life markers was measured using the Mini Nutritional Assessment (MNA), Timed Up and Go (TUG) and EQ-5D-5L, respectively, at baseline and after home-based dietetic intervention. RESULTS: Participants (n = 99) were recruited from consecutive referrals. Participant's weight, body mass index (BMI), total daily energy and protein intake, MNA total score, and TUG significantly improved after a 3-month nutrition intervention (effect sizes 0.257, 0.257, 0.580, 0.533, 0.577 and 0.281, respectively). The most common interventions dietitians utilised were nutrition education, use of oral nutritional supplements (ONS) and meal fortification. In total, 339 dietetic interventions were recommended to participants at baseline with 197 (58.11%) implemented at 3 months, with meal planning and referral to other relevant allied health or Commonwealth Home Support Program (CHSP) services the most implemented interventions. CONCLUSIONS: Home-based dietetic intervention improves nutritional status, functional status and quality of life in community-dwelling older adults referred for dietetic input. Improvements observed in nutritional and functional status were consistent with benchmarks of change from published literature.

Intra-generational social mobility and mortality among older men in the Concord Health and Ageing in Men Project: A cohort study.

Objectives: We examined associations between intra-generational social mobility (reflected in life-course socioeconomic trajectories) and mortality, among older men. Methods: Data came from a prospective Australian community-based cohort of older men. Social mobility was defined by socioeconomic indicators from three points in the life-course: educational attainment (late adolescence-early adulthood), occupation (mid-life), and current sources of income (older age). We defined indicators of social mobility trajectory (6 categories; reflecting the direction of social mobility) and social mobility status (2 categories; mobile or non-mobile). We used Cox regression to examine associations with mortality, adjusting for age, country of birth, and living arrangement. Results: We followed 1568 men (mean age 76.8, SD 5.4) for a mean duration of 9.1 years, with 797 deaths recorded. Moving upward was the predominant social mobility trajectory (36.0%), followed by mixed trajectories (25.1%), downward (15.1%), stable low (12.2%), stable high (7.6%), and stable middle (4.0%). Men with downward (Hazard ratio 1.58, 95% CI 1.13 to 2.19) and stable low socioeconomic trajectories (1.77, 1.25 to 2.50) had higher mortality risks than men with stable high socioeconomic trajectories, while men with upward trajectories had similar risks to those with stable high trajectories. 76.2% of the participants were classified as having mobile status; no associations were evident between binary social mobility status and mortality. Discussions: These findings suggest cumulative and persistent exposure to disadvantaged socioeconomic conditions across the life-course, rather than social mobility, is associated with increased mortality. For each stage of the life-course, addressing socioeconomic disadvantage may reduce inequities in mortality.

Feasibility and acceptability of facilitated advance care planning in outpatient clinics: A qualitative study of health-care professionals experience.

OBJECTIVE: This study sought to determine the feasibility and acceptability of a facilitated advance care planning (ACP) intervention implemented in outpatient clinics, as perceived by health-care professionals (HCPs). METHODS: Data from seven focus groups (n = 27) and nine semi-structured interviews with HCPs recruited as part of a pragmatic, randomised controlled trial (RCT) were analysed using qualitative descriptive methodology. Components of the intervention included HCP education and training, tools to assist HCPs with patient selection, hardcopy information, and ACP documentation, and specialised nurse-facilitators to support HCPs to complete ACP conversations and documentation with patients and caregivers. RESULTS: Health-care professionals working in tertiary outpatient clinics perceived the facilitated ACP intervention as feasible and acceptable. Health-care professionals reported a high level of satisfaction with key elements of the intervention, including the specialised education and training, screening and assessment procedures and ongoing support from the nurse-facilitators. Health-care professionals reported this training and support increased their confidence and ACP knowledge, leading to more frequent ACP discussions with patients and their families. Health-care professionals noted their ability to conduct ACP screening and assessment in clinic was impeded by large clinical caseloads and patient-related factors (e.g., dementia diagnoses, and emotional distress). Additional barriers to ACP implementation identified by HCPs included poor collaboration, constrained time and clinical space, undefined roles and standardised recording procedures for HCPs. CONCLUSIONS: Facilitated ACP intervention in outpatient clinics is perceived by HCPs as feasible and acceptable. Addressing barriers and tailoring implementation strategies may improve the delivery of ACP as part of tertiary outpatient care.

Feasibility and Acceptability of Facilitated Advance Care Planning in Outpatient Clinics: A Qualitative Study of Patient and Caregivers Experiences.

Guidelines recommend advance care planning (ACP) for people with advanced illness; however, evidence supporting ACP as a component of outpatient care is lacking. We sought to establish the feasibility and acceptability of a facilitated ACP intervention for people attending tertiary outpatient clinics. Data from 20 semi-structured interviews with patient (M = 79.3 ± 7.7, 60% male) and caregiver (M = 68.1 ± 11.0, 60% female) participants recruited as part of a pragmatic, randomized controlled trial (RCT) were analyzed using qualitative descriptive methodology. Patients were randomized to intervention (e.g., facilitated support) or control (e.g., standard care). Intervention patients expressed high satisfaction, reporting the facilitated ACP session was clear, straightforward, and suited to their needs. Intervention caregivers did not report any significant concerns with the facilitated ACP process. Control participants reported greater difficulty completing ACP compared to intervention participants. Embedding facilitated ACP into tertiary outpatient care appears feasible and acceptable for people with advanced illnesses.

Dementia subtypes, cognitive decline and survival among older adults attending a memory clinic in Cape Town, South Africa: a retrospective study.

BACKGROUND: There are no published longitudinal studies from Africa of people with dementia seen in memory clinics. The aim of this study was to determine the proportions of the different dementia subtypes, rates of cognitive decline, and predictors of survival in patients diagnosed with dementia and seen in a memory clinic. METHODS: Data were collected retrospectively from clinic records of patients aged ≥ 60 seen in the memory clinic at Groote Schuur Hospital, Cape Town, South Africa over a 10-year period. Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria were used to identify patients with Major Neurocognitive Disorders (dementia). Additional diagnostic criteria were used to determine the specific subtypes of dementia. Linear regression analysis was used to determine crude rates of cognitive decline, expressed as mini-mental state examination (MMSE) points lost per year. Changes in MMSE scores were derived using mixed effects modelling to curvilinear models of cognitive change, with time as the dependent variable. Multivariable cox survival analysis was used to determine factors at baseline that predicted mortality. RESULTS: Of the 165 patients who met inclusion criteria, 117(70.9%) had Major Neurocognitive Disorder due to Alzheimer's disease (AD), 24(14.6%) Vascular Neurocognitive Disorder (VND), 6(3.6%) Dementia with Lewy Bodies (DLB), 5(3%) Parkinson disease-associated dementia (PDD), 3(1.8%) fronto-temporal dementia, 4(2.4%) mixed dementia and 6(3.6%) other types of dementia. The average annual decline in MMSE points was 2.2(DLB/PDD), 2.1(AD) and 1.3(VND). Cognitive scores at baseline were significantly lower in patients with 8 compared to 13 years of education and in those with VND compared with AD. Factors associated with shorter survival included age at onset greater than 65 (HR = 1.82, 95% C.I. 1.11, 2.99, p = 0.017), lower baseline MMSE (HR = 1.05, 95% C.I. 1.01, 1.10, p = 0.029), Charlson's comorbidity scores of 3 to 4 (HR = 1.88, 95% C.I. 1.14, 3.10, p = 0.014), scores of 5 or more (HR = 1.97, 95% C.I. 1.16, 3.34, p = 0.012) and DLB/PDD (HR = 3.07, 95% C.I. 1.50, 6.29, p = 0.002). Being female (HR = 0.59, 95% C.I.0.36, 0.95, p = 0.029) was associated with longer survival. CONCLUSIONS: Knowledge of dementia subtypes, the rate and factors affecting cognitive decline and survival outcomes will help inform decisions about patient selection for potential future therapies and for planning dementia services in resource-poor settings.

Screening for cancer beyond recommended upper age limits: views and experiences of older people.

BACKGROUND: Internationally, screening programmes and clinical practice guidelines recommend when older adults should stop cancer screening using upper age limits, but it is unknown how older adults view these recommendations. OBJECTIVE: To examine older adults' views and experiences about continuing or stopping cancer screening beyond the recommended upper age limit for breast, cervical, prostate and bowel cancer. DESIGN: Qualitative, semi-structured interviews. SETTING: Australia, telephone. SUBJECTS: A total of 29 community-dwelling older adults (≥70-years); recruited from organisation newsletters, mailing lists and Facebook advertisements. METHODS: Interviews were audio-recorded, transcribed and analysed thematically using Framework Analysis. RESULTS: Firstly, older adults were on a spectrum between trusting recommendations and actively deciding about cancer screening, with some who were uncertain. Secondly, participants reported limited in-depth discussions with health professionals about cancer screening. In primary care, discussions were focused on checking they were up to date with screening or going over results. Discussions mostly only occurred if older adults initiated themselves. Finally, participants had a socially- and self-constructed understanding of screening recommendations and potential outcomes. Perceived reasons for upper age limits were cost, reduced cancer risk or ageism. Risks of screening were understood in relation to their own social experiences (e.g. shared stories about friends with adverse outcomes of cancer treatment or conversations with friends/family about controversy around prostate screening). CONCLUSIONS: Direct-to-patient information and clinician support may help improve communication about the changing benefit to harm ratio of cancer screening with increasing age and increase understanding about the rationale for an upper age limit for cancer screening programmes.

Factors associated with frailty in geriatric patients with and without sarcopenia in Vietnam.

OBJECTIVES: This study aimed to investigate the relationship between sarcopenia and frailty and examine factors associated with frailty among older patients with and without sarcopenia. METHODS: This cross-sectional study was conducted on older inpatients and outpatients in Vietnam. Participants aged 60 years or older were consecutively enrolled in the study. Sarcopenia was defined using the Asian Working Group for Sarcopenia (AWGS) 2019 criteria. Fried's frailty phenotype was applied to define frailty. Logistic regression models with frailty as the dependent variable were applied. RESULTS: A total of 835 patients (mean age: 71.3 years, SD 8.4) were recruited. The overall prevalence of frailty was 17%. Among participants with and without frailty, 92% and 47% had sarcopenia, respectively. In unadjusted analysis, sarcopenia was significantly associated with increased frailty (OR 12.3, 95% CI 6.7-22.6) and remained significant after adjustment for sociodemographic factors (OR 6.3, 95% CI: 3.0-12.6) and for both sociodemographic and clinical factors (OR 5.4, 95% CI: 2.4-12.2). Among participants with sarcopenia, older age, inpatient status, having a high risk for falls, malnutrition and a history of hospitalisation in the last year were significantly associated with frailty. Among participants without sarcopenia, the factors associated with frailty were older age, inpatient status, low educational level, high risk of falls and malnutrition. CONCLUSIONS: Our study results highlighted that sarcopenia and frailty are two related but distinct geriatric syndromes.

Provision of domiciliary dental service to residential aged care facilities: A 3-year descriptive summary.

AIM: This cross-sectional descriptive study described the oral health status and types of domiciliary dental treatment received by residents living in residential care after an oral health assessment (OHAT). METHODS: Twenty-one facilities were recruited where consenting participants received OHAT followed by a referral for further domiciliary dental treatments. Data were captured and stored as Reach-OHT database where 2017-2019 data were analyzed. RESULT: Overall, 88% of residents consented. 69.1% were referred for treatment after completion of OHAT. More than half had one or more caries; 40% showed sign of periodontal disease; a higher proportion of dentate participants had an unsatisfactory level of oral cleanliness. Of those received domiciliary dental treatment, diagnostic and preventive service was the combination most frequently provided. These comprised an average of 71.9% of total treatment provided across the 3-year period. CONCLUSION: This study contributes to the understanding and knowledge around the provision of domiciliary dental services in residential care. A large number of older people in residential care can be assessed and treated through a domiciliary service pathway. As the vast majority of services provided were diagnostic, preventive, and restorative care, the feasibility of utilizing the skillset of the entire dental team should be explored.

Sarcopenia prevalence and functional outcomes in older men with obesity: Comparing the use of the EWGSOP2 sarcopenia versus ESPEN-EASO sarcopenic obesity consensus definitions.

BACKGROUND & AIMS: The potential for older adults with obesity to also have sarcopenia, and the health consequences of 'sarcopenic obesity', may be underappreciated by health professionals. The primary aim of this secondary analysis of a prospective cohort study of older men was to explore the prevalence and functional outcomes of sarcopenic obesity based on different consensus definitions. METHODS: 1416 community-dwelling men aged ≥70 years were classified into sarcopenia categories according to the European Working Group on Sarcopenia in Older People (EWGSOP2) definition, and sarcopenic obesity categories according to the European Society for Clinical Nutrition and Metabolism and the European Association for the Study of Obesity (ESPEN-EASO) definition. Descriptive analyses determined prevalence of sarcopenia in obese and non-obese older men. Multivariable analyses compared associations with functional outcomes including activity of daily living (ADL) and instrumental activity of daily living (IADL) disability and 12-month incident falls. RESULTS: According to the EWGSOP2 definition, 12.6% of men had confirmed sarcopenia but only 0.3% of men had sarcopenia and obesity (BMI ≥30 kg/m2). Conversely, 9.6% of men had sarcopenic obesity according to the ESPEN-EASO definition. Notably, no men with a BMI ≥32 kg/m2 were classified as having EWGSOP2-confirmed sarcopenia, despite the fact that 60.8% of all men with BMI ≥32 kg/m2 had low muscle strength. Due to low numbers (N = 4) of obese older men with EWGSOP2-confirmed sarcopenia, associations with functional outcomes were not assessed. Men with sarcopenic obesity according to the ESPEN-EASO definition had significantly lower hand grip strength, higher chair-stands time and slower gait speed (all P < 0.05), increased odds for ADL (odds ratio: 5.02, 95% CI: 1.85-13.58) and IADL (2.18, 1.38-3.45) disability, and higher 12-month incident falls rates (incident rate ratio: 1.59, 95% CI: 1.03-2.44) than men with neither sarcopenia nor obesity. CONCLUSION: Low muscle strength is common in older men with obesity, but the prevalence of sarcopenia is likely to be underestimated when the EWGSOP2 operational definition is applied in this population. The ESPEN-EASO operational definition of sarcopenic obesity appears to provide a valid approach for identifying older men with obesity who are at risk of poor functional outcomes related to sarcopenia.

Physical activity and injurious falls in older Australian women: adjusted associations and modification by physical function limitation and frailty in the Australian Longitudinal Study on Women's Health.

OBJECTIVES: To investigate associations between leisure-time physical activity (LPA) and injurious falls in older women and explore modification of associations by physical function and frailty. METHODS: Women born during 1946-51 from the Australian Longitudinal Study on Women's Health, injurious falls (self-reported fall with injury and/or medical attention) and self-reported weekly LPA (duration and type). We undertook cross-sectional and prospective analyses using data from 2016 [n = 8,171, mean (SD) age 68 (1)] and 2019 surveys (n = 7,057). Associations were quantified using directed acyclic graph-informed logistic regression and effect modification examined using product terms. RESULTS: Participation in LPA as recommended by World Health Organization (150-300 min/week) was associated with lower odds of injurious falls in cross-sectional (adjusted Odds Ratio (OR) 0.74, 95% CI 0.61-0.90) and prospective analyses (OR 0.75, 95% CI 0.60-0.94). Compared with those who reported no LPA, cross-sectionally, odds of injurious falls were lower in those who reported brisk walking (OR 0.77, 95% CI 0.67-0.89) and vigorous LPA (OR 0.86, 95% CI 0.75-1.00). No significant association was found between different types of LPA and injurious falls prospectively. Only cross-sectionally, physical function limitation and frailty modified the association between LPA and injurious falls, with tendencies for more injurious falls with more activity in those with physical limitation or frailty, and fewer injurious falls with more activity among those without physical function limitation or frailty. CONCLUSION: Participation in recommended levels of LPA was associated with lower odds of injurious falls. Caution is required when promoting general physical activity among people with physical limitation or frailty.

Factors Influencing Primary Care Practitioners' Cancer Screening Recommendations for Older Adults: a Systematic Review.

BACKGROUND: Primary care practitioners (PCPs) play a key role in cancer screening decisions for older adults (≥ 65 years), but recommendations vary by cancer type and jurisdiction. PURPOSE: To examine the factors influencing PCPs' recommendations for breast, cervical, prostate, and colorectal cancer screening for older adults. DATA SOURCES: MEDLINE, Pre-Medline, EMBASE, PsycINFO, and CINAHL, searched from 1 January 2000 to July 2021, and citation searching in July 2022. STUDY SELECTION: Assessed factors influencing PCPs' breast, prostate, colorectal, or cervical cancer screening decisions for older adults' (defined either as ≥ 65 years or < 10-year life expectancy). DATA EXTRACTION: Two authors independently conducted data extraction and quality appraisal. Decisions were crosschecked and discussed where necessary. DATA SYNTHESIS: From 1926 records, 30 studies met inclusion criteria. Twenty were quantitative, nine were qualitative, and one used a mixed method design. Twenty-nine were conducted in the USA, and one in the UK. Factors were synthesized into six categories: patient demographic characteristics, patient health characteristics, patient and clinician psycho-social factors, clinician characteristics, and health system factors. Patient preference was most reported as influential across both quantitative and qualitative studies. Age, health status, and life expectancy were also commonly influential, but PCPs held nuanced views about life expectancy. Weighing benefits/harms was also commonly reported with variation across cancer screening types. Other factors included patient screening history, clinician attitudes/personal experiences, patient/provider relationship, guidelines, reminders, and time. LIMITATIONS: We could not conduct a meta-analysis due to variability in study designs and measurement. The vast majority of included studies were conducted in the USA. CONCLUSIONS: Although PCPs play a role in individualizing cancer screening for older adults, multi-level interventions are needed to improve these decisions. Decision support should continue to be developed and implemented to support informed choice for older adults and assist PCPs to consistently provide evidence-based recommendations.

Deprescribing to optimise health outcomes for frail older people: a double-blind placebo-controlled randomised controlled trial-outcomes of the Opti-med study.

BACKGROUND: potentially harmful polypharmacy is very common in older people living in aged care facilities. To date, there have been no double-blind randomised controlled studies of deprescribing multiple medications. METHODS: three-arm (open intervention, blinded intervention and blinded control) randomised controlled trial enrolling people aged over 65 years (n = 303, noting pre-specified recruitment target of n = 954) living in residential aged care facilities. The blinded groups had medications targeted for deprescribing encapsulated while the medicines were deprescribed (blind intervention) or continued (blind control). A third open intervention arm had unblinded deprescribing of targeted medications. RESULTS: participants were 76% female with mean age 85.0 ± 7.5 years. Deprescribing was associated with a significant reduction in the total number of medicines used per participant over 12 months in both intervention groups (blind intervention group -2.7 medicines, 95% CI -3.5, -1.9, and open intervention group -2.3 medicines; 95% CI -3.1, -1.4) compared with the control group (-0.3, 95% CI -1.0, 0.4, P = 0.053). Deprescribing regular medicines was not associated with any significant increase in the number of 'when required' medicines administered. There were no significant differences in mortality in the blind intervention group (HR 0.93, 95% CI 0.50, 1.73, P = 0.83) or the open intervention group (HR 1.47, 95% CI 0.83, 2.61, P = 0.19) compared to the control group. CONCLUSIONS: deprescribing of two to three medicines per person was achieved with protocol-based deprescribing during this study. Pre-specified recruitment targets were not met, so the impact of deprescribing on survival and other clinical outcomes remains uncertain.
