Potentially Modifiable Risk Factors for Dementia and Mild Cognitive Impairment: An Umbrella Review and Meta-Analysis.

INTRODUCTION: The prevalence of mild and major neurocognitive disorders (NCDs), also referred to as mild cognitive impairment and dementia, is rising globally. The prevention of NCDs is a major global public health interest. We sought to synthesize the literature on potentially modifiable risk factors for NCDs. METHODS: We conducted an umbrella review using a systematic search across multiple databases to identify relevant systematic reviews and meta-analyses. Eligible reviews examined potentially modifiable risk factors for mild or major NCDs. We used a random-effects multi-level meta-analytic approach to synthesize risk ratios for each risk factor while accounting for overlap in the reviews. We further examined risk factors for major NCD due to two common etiologies: Alzheimer's disease and vascular dementia. RESULTS: A total of 45 reviews with 212 meta-analyses were synthesized. We identified fourteen broadly defined modifiable risk factors that were significantly associated with these disorders: alcohol consumption, body weight, depression, diabetes mellitus, diet, hypertension, less education, physical inactivity, sensory loss, sleep disturbance, smoking, social isolation, traumatic brain injury, and vitamin D deficiency. All 14 factors were associated with the risk of major NCD, and five were associated with mild NCD. We found considerably less research for vascular dementia and mild NCD. CONCLUSION: Our review quantifies the risk associated with 14 potentially modifiable risk factors for mild and major NCDs, including several factors infrequently included in dementia action plans. Prevention strategies should consider approaches that reduce the incidence and severity of these risk factors through health promotion, identification, and early management.

Psychotropic, Anticonvulsant, and Opioid Use in Assisted Living Residents Before and During the COVID-19 Pandemic.

OBJECTIVES: To examine the associations between COVID-19 pandemic waves (1-4) and prevalent antipsychotic, antidepressant, benzodiazepine, anticonvulsant, and opioid use among assisted living (AL) residents, by setting (dementia care vs other). DESIGN: Population-based, repeated cross-sectional study. SETTING AND PARTICIPANTS: Linked clinical and health administrative databases for residents of all publicly subsidized AL homes (N = 256) in Alberta, Canada, examined from January 2018 to December 2021. Setting-specific quarterly cohorts of residents were derived for pandemic (starting March 1, 2020) and comparable historical (2018/2019 combined) periods. METHODS: The quarterly proportion of residents dispensed an antipsychotic, antidepressant, benzodiazepine, anticonvulsant, or opioid was examined for each setting and period. Log-binomial generalized estimating equations models estimated prevalence ratios (PR) for period (pandemic vs historical quarterly periods), setting (dementia care vs other AL), and period-setting interactions. RESULTS: On March 1, 2020, there were 2874 dementia care and 6611 other AL residents (mean age 82.4 vs 79.9 years, 68.2% vs 66.1% female, 93.5% vs 42.6% with dementia, respectively). Antipsychotic use increased during waves 2 to 4 for residents of both settings, but this increase was significantly greater for dementia care than other AL residents during waves 3 and 4 (eg, wave 3, PR 1.21, 95% CI 1.14-1.27 vs PR 1.12, 95% CI 1.07-1.17, interaction term P = .029). In both settings, there was a significant but modest increase in antidepressant use and a significant decrease in benzodiazepine use during several pandemic waves. For other AL residents only, there was a small statistically significant increase in anticonvulsant use during waves 2 to 4. No significant pandemic effect was observed for prevalent opioid use in either setting. CONCLUSIONS AND IMPLICATIONS: The persistence of the pandemic-associated increase in antipsychotic, antidepressant, and anticonvulsant use in AL residents, and greater increase in antipsychotic use for dementia care settings, raises concerns about the attendant risks for residents, especially those with dementia.

Sex differences in the association of sleep spindle density and cognitive performance among community-dwelling middle-aged and older adults with obstructive sleep apnea.

Recent studies have found associations between obstructive sleep apnea and cognitive decline. The underlying mechanisms are still unclear. Here, we investigate the associations between changes in micro-architecture, specifically sleep spindles, and cognitive function in community-dwelling middle-aged and older adults, some with obstructive sleep apnea, with a focus on sex differences. A total of 125 voluntary participants (mean age 66.0 ± 6.4 years, 64 females) from a larger cohort (participants of the Brain in Motion Studies I and II) underwent 1 night of in-home polysomnography and a neuropsychological battery (sleep and cognitive testing were conducted within 2 weeks of each other). A semi-automatic computerized algorithm was used to score polysomnography data and detect spindle characteristics in non-rapid eye movement Stages 2 and 3 in both frontal and central electrodes. Based on their apnea-hypopnea index, participants were divided into those with no obstructive sleep apnea (apnea-hypopnea index < 5 per hr, n = 21), mild obstructive sleep apnea (5 ≥ apnea-hypopnea index < 15, n = 47), moderate obstructive sleep apnea (15 ≥ apnea-hypopnea index < 30, n = 34) and severe obstructive sleep apnea (apnea-hypopnea index ≥ 30, n = 23). There were no significant differences in spindle characteristics between the four obstructive sleep apnea severity groups. Spindle density and percentage of fast spindles were positively associated with some verbal fluency measures on the cognitive testing. Sex might be linked with these associations. Biological sex could play a role in the associations between spindle characteristics and some verbal fluency measures. Obstructive sleep apnea severity was not found to be a contributing factor in this non-clinical community-dwelling cohort.

Comparing quality of care outcomes between assisted living and nursing homes before and during the COVID-19 pandemic.

BACKGROUND: While assisted living (AL) and nursing home (NHs) residents in share vulnerabilities, AL provides fewer staffing resources and services. Research has largely neglected AL, especially during the COVID-19 pandemic. Our study compared trends of practice-sensitive, risk-adjusted quality indicators between AL and NHs, and changes in these trends after the start of the pandemic. METHODS: This repeated cross-sectional study used population-based resident data in Alberta, Canada. Using Resident Assessment Instrument data (01/2017-12/2021), we created quarterly cohorts, using each resident's latest assessment in each quarter. We applied validated inclusion/exclusion criteria and risk-adjustments to create nine quality indicators and their 95% confidence intervals (CIs): potentially inappropriate antipsychotic use, pain, depressive symptoms, total dependency in late-loss activities of daily living, physical restraint use, pressure ulcers, delirium, weight loss, urinary tract infections. Run charts compared quality indicators between AL and NHs over time and segmented regressions assessed whether these trends changed after the start of the pandemic. RESULTS: Quarterly samples included 2015-2710 AL residents and 12,881-13,807 NH residents. Antipsychotic use (21%-26%), pain (20%-24%), and depressive symptoms (17%-25%) were most common in AL. In NHs, they were physical dependency (33%-36%), depressive symptoms (26%-32%), and antipsychotic use (17%-22%). Antipsychotic use and pain were consistently higher in AL. Depressive symptoms, physical dependency, physical restraint use, delirium, weight loss were consistently lower in AL. The most notable segmented regression findings were an increase in antipsychotic use during the pandemic in both settings (AL: change in slope = 0.6% [95% CI: 0.1%-1.0%], p = 0.0140; NHs: change in slope = 0.4% [95% CI: 0.3%-0.5%], p < 0.0001), and an increase in physical dependency in AL only (change in slope = 0.5% [95% CI: 0.1%-0.8%], p = 0.0222). CONCLUSIONS: QIs differed significantly between AL and NHs before and during the pandemic. Any changes implemented to address deficiencies in either setting need to account for these differences and require monitoring to assess their impact.

Social participation of older people in urban and rural areas: Canadian Longitudinal Study on Aging.

BACKGROUND AND OBJECTIVES: Although the positive influence of social activity on health is now well-established, a complex relationship exists among social participation, personal, social and the environment. Social participation of older adults was examined in rural and urban settings to identify features of the built-environment and perception of neighborhood specific to the locale. RESEARCH DESIGN AND METHODS: Using cross-sectional data from the Canadian Longitudinal Study on Aging (CLSA), we examined social participation and health of older people (65 + yrs) in relation to the built environment and sociocultural contexts for urban and rural areas. A social participation index was derived from responses on the frequency of participating in 8 social activities over the past 12 months. Personal, household and neighborhood indicators were examined to develop multivariable regression models for social participation in urban and rural cohorts. RESULTS: No meaningful differences were seen with the frequency of social participation between rural and urban settings; however, the type of community-related activities differed in that a greater proportion of urban participants reported sports and educational/cultural events than rural participants. Service club activities were greater for rural than urban participants. Different neighborhood features were statistically significant factors in explaining social participation in rural than in urban locales, although transportation was a significant factor regardless of locale. Trustworthiness, belonging and safety were perceived factors of the neighborhood associated with higher social participation for rural participants. DISCUSSION AND IMPLICATIONS: The relationship between home and health becomes stronger as one ages. Social and physical features of built environment specific to urban and rural settings need to be considered when implementing appropriate social activities for older people.

Effect of a Continuous Bedside Pressure Mapping System for Reducing Interface Pressures: A Randomized Clinical Trial.

Importance: Continuous bedside pressure mapping (CBPM) technology can assist in detecting skin areas with excessive interface pressure and inform efficient patient repositioning to prevent the development of pressure injuries (PI). Objective: To evaluate the efficacy of CBPM technology in reducing interface pressure and the incidence of PIs. Design, Setting, and Participants: This parallel, 2-group randomized clinical trial was performed at a tertiary acute care center. The study started to enroll participants in December 2014 and was completed in May 2018. Participants included adults partially or completely dependent for bed mobility. Statistical analysis was performed from September 2018 to December 2022. Intervention: Nursing staff using visual feedback from CBPM technology for 72 hours. Main Outcomes and Measures: Absolute number of sensing points with pressure readings greater than 40 mm Hg, mean interface pressure across all sensing points under a patient's body, proportion of participants who had pressure readings greater than 40 mm Hg, and pressure-related skin and soft tissue changes. Results: There were 678 patients recruited. After attrition, 260 allocated to the control group (151 [58.1%] male; mean [SD] age, 61.9 [18.5] years) and 247 in the intervention group (147 [59.5%] male; mean [SD] age, 63.6 [18.1] years) were included in analyses. The absolute number of sensing points with pressures greater than 40 mm Hg were 11 033 in the control group vs 9314 in the intervention group (P = .16). The mean (SD) interface pressure was 6.80 (1.63) mm Hg in the control group vs 6.62 (1.51) mm Hg in the intervention group (P = .18). The proportion of participants who had pressure readings greater than 40 mm Hg was 99.6% in both the control and intervention groups. Conclusions and Relevance: In this randomized clinical trial to evaluate the efficacy of CBPM technology in the reduction of interface pressure and the incidence of PIs in a tertiary acute care center, no statistically significant benefit was seen for any of the primary outcomes. These results suggest that longer duration of monitoring and adequately powered studies where CBPM feedback is integrated into a multifaceted intervention to prevent PI are needed. Trial Registration: ClinicalTrials.gov Identifier: NCT02325388.

Pharmacists' knowledge, perceptions and practices regarding frailty: A cross-sectional survey across practice settings in Canada.

Background: Data on Canadian pharmacists' knowledge and perceptions about frailty in older adults and its assessment in pharmacy practice are scarce. Methods: A cross-sectional survey of 349 Canadian pharmacists was conducted to evaluate pharmacists' knowledge, perceptions and practices regarding frailty. Descriptive analyses summarized responses by practice setting, and a multivariable logistic regression model examined associations between respondent characteristics and the likelihood of assessing frailty. Results: Most respondents were female (70%), aged ≤34 years (47%), Canadian graduates (83%), from Ontario/Quebec (51%) and from urban centres (58%). Although a significant proportion agreed it is important for pharmacists to know (80%) and assess (56%) patient frailty status, only 36% reported assessing frailty in practice. Respondents exclusively practising in a community pharmacy were significantly less likely to agree that it is important for a pharmacist to know or assess frailty status and to report assessing it. Factors associated with a greater likelihood of assessment included positive beliefs about the importance of knowing a patient's frailty status and having a greater proportion of older patients with cognitive or functional impairment in practice. Discussion: Findings suggest that pharmacists generally agree with the importance of understanding frailty as it relates to the appropriate use of medications, but most do not assess it. Further research is needed to identify the barriers to assessing frailty, while guidance is needed on which of the available screening tools can best be integrated into a clinical pharmacy practice. Conclusion: There is an opportunity to improve pharmaceutical care for older adults by providing pharmacists the means and resources to assess frailty in practice.

Caregiver Involvement and Concerns with Care of Residents of Assisted Living before and during the COVID-19 Pandemic.

INTRODUCTION: Family/friend caregivers play an essential role in promoting the physical and mental health of older adults in need of care - especially during the COVID-19 pandemic and especially in assisted living (AL) homes, where resident care needs are similarly complex as in long-term care homes but fewer staffing resources and services are available. However, little research is available on caregiver involvement and concerns with care of AL residents prior to and during waves 1 and 2 of the COVID-19 pandemic. This study addressed this important knowledge gap. METHODS: This prospective cohort study used baseline and follow-up online surveys with primary caregivers to AL residents in Western Canada who were 65 years or older and had lived in the AL home for at least 3 months before Mar 1, 2020. Surveys assessed the following outcomes in the 3 months prior to and during waves 1 and 2 of the pandemic: sociodemographics, 5 ways of visiting or communicating with residents, involvement in 16 care tasks, concerns with 9 resident physical/mental health conditions, perceived lack of resident access to 7 care services, and whether caregivers felt well informed and involved with resident care. RESULTS: Based on 386 caregiver responses, in-person visits dropped significantly in wave 1 of the pandemic and so did caregiver involvement in nearly all care tasks. While these rates increased in wave 2, most did not return to pre-pandemic levels. Correspondingly, caregiver concerns (already high before the pandemic) substantially increased in wave 1 and stayed high in wave 2. These were particularly elevated among caregivers who did not feel well informed/involved with resident care. CONCLUSIONS: Restricted in-person visiting disrupted resident care and was associated with worse perceptions of resident health and well-being. Continued caregiver involvement in resident care and communication with caregivers even during lockdowns is key to mitigating these issues.

Why should clinical practitioners ask about their patients' concerns about falling?

Concerns (or 'fears') about falling (CaF) are common in older adults. As part of the 'World Falls Guidelines Working Group on Concerns about Falling', we recommended that clinicians working in falls prevention services should regularly assess CaF. Here, we expand upon these recommendations and argue that CaF can be both 'adaptive' and 'maladaptive' with respect to falls risk. On the one hand, high CaF can lead to overly cautious or hypervigilant behaviours that increase the risk of falling, and may also cause undue activity restriction ('maladaptive CaF'). But concerns can also encourage individuals to make appropriate modifications to their behaviour to maximise safety ('adaptive CaF'). We discuss this paradox and argue that high CaF-irrespective of whether 'adaptive' or 'maladaptive'-should be considered an indication that 'something is not right', and that is represents an opportunity for clinical engagement. We also highlight how CaF can be maladaptive in terms of inappropriately high confidence about one's balance. We present different routes for clinical intervention based on the types of concerns disclosed.

Exploring data reduction strategies in the analysis of continuous pressure imaging technology.

BACKGROUND: Science is becoming increasingly data intensive as digital innovations bring new capacity for continuous data generation and storage. This progress also brings challenges, as many scientific initiatives are challenged by the shear volumes of data produced. Here we present a case study of a data intensive randomized clinical trial assessing the utility of continuous pressure imaging (CPI) for reducing pressure injuries. OBJECTIVE: To explore an approach to reducing the amount of CPI data required for analyses to a manageable size without loss of critical information using a nested subset of pressure data. METHODS: Data from four enrolled study participants excluded from the analytical phase of the study were used to develop an approach to data reduction. A two-step data strategy was used. First, raw data were sampled at different frequencies (5, 30, 60, 120, and 240 s) to identify optimal measurement frequency. Second, similarity between adjacent frames was evaluated using correlation coefficients to identify position changes of enrolled study participants. Data strategy performance was evaluated through visual inspection using heat maps and time series plots. RESULTS: A sampling frequency of every 60 s provided reasonable representation of changes in interface pressure over time. This approach translated to using only 1.7% of the collected data in analyses. In the second step it was found that 160 frames within 24 h represented the pressure states of study participants. In total, only 480 frames from the 72 h of collected data would be needed for analyses without loss of information. Only ~ 0.2% of the raw data collected would be required for assessment of the primary trial outcome. CONCLUSIONS: Data reduction is an important component of big data analytics. Our two-step strategy markedly reduced the amount of data required for analyses without loss of information. This data reduction strategy, if validated, could be used in other CPI and other settings where large amounts of both temporal and spatial data must be analysed.

Development and validation of a hospital frailty risk measure using Canadian clinical administrative data.

BACKGROUND: Accessible measures specific to the Canadian context are needed to support health system planning for older adults living with frailty. We sought to develop and validate the Canadian Institute for Health Information (CIHI) Hospital Frailty Risk Measure (HFRM). METHODS: Using CIHI administrative data, we conducted a retrospective cohort study involving patients aged 65 years and older who were discharged from Canadian hospitals from Apr. 1, 2018, to Mar. 31, 2019. We used a 2-phase approach to develop and validate the CIHI HFRM. The first phase, construction of the measure, was based on the deficit accumulation approach (identification of age-related conditions using a 2-year look-back). The second phase involved refinement into 3 formats (continuous risk score, 8 risk groups and binary risk measure), with assessment of their predictive validity for several frailty-related adverse outcomes using data to 2019/20. We assessed convergent validity with the United Kingdom Hospital Frailty Risk Score. RESULTS: The cohort consisted of 788 701 patients. The CIHI HFRM included 36 deficit categories and 595 diagnosis codes that cover morbidity, function, sensory loss, cognition and mood. The median continuous risk score was 0.111 (interquartile range 0.056-0.194, equivalent to 2-7 deficits); 35.1% (n = 277 000) of the cohort were found at risk of frailty (≥ 6 deficits). The CIHI HFRM showed satisfactory predictive validity and reasonable goodness-of-fit. For the continuous risk score format (unit = 0.1), the hazard ratio (HR) for 1-year risk of death was 1.39 (95% confidence interval [CI] 1.38-1.41), with a C-statistic of 0.717 (95% CI 0.715-0.720); the odds ratio for high users of hospital beds was 1.85 (95% CI 1.82-1.88), with a C-statistic of 0.709 (95% CI 0.704-0.714), and the HR of 90-day admission to long-term care was 1.91 (95% CI 1.88-1.93), with a C-statistic of 0.810 (95% CI 0.808-0.813). Compared with the continuous risk score, using a format of 8 risk groups had similar discriminatory ability and the binary risk measure had slightly weaker performance. INTERPRETATION: The CIHI HFRM is a valid tool showing good discriminatory power for several adverse outcomes. The tool can be used by decision-makers and researchers by providing information on hospital-level prevalence of frailty to support system-level capacity planning for Canada's aging population.

Expert elicitation of risk factors for progression to dementia in individuals with mild cognitive impairment.

INTRODUCTION: This study assesses experts' beliefs about important predictors of developing dementia in persons with mild cognitive impairment (MCI). METHODS: Structured expert elicitation, a methodology to quantify expert knowledge, was used to elicit the most important risk factors for developing dementia. We recruited 11 experts (6 neurologists, 3 geriatricians, and 2 psychiatrists). Ten experts fully participated in introductory meetings, two rounds of surveys, and discussion meetings. The data from these ten experts were utilized for this study. RESULTS: The expert elicitation identified age, CSF analysis, fluorodeoxyglucose-positron emission tomography (FDG-PET) findings, hippocampal atrophy, MoCA (or MMSE) score, parkinsonism, apathy, psychosis, informant report of cognitive symptoms, and global atrophy as the ten most important predictors of progressing to dementia in persons with MCI. DISCUSSION: Several dementia predictors are not routinely collected in existing registries, observational studies, or usual care. This might partially explain the low uptake of existing published dementia risk scores in clinical practice.

Elicited clinician knowledge did not improve dementia risk prediction in individuals with mild cognitive impairment.

OBJECTIVES: This study aims to develop and validate a Bayesian risk prediction model that combines research cohort data with elicited expert knowledge to predict dementia progression in people with mild cognitive impairment (MCI). STUDY DESIGN AND SETTING: This is a prognostic risk prediction modeling study based on cohort data (Alzheimer's disease neuroimaging initiative [ADNI]; n = 365) of research participants with MCI and elicited expert data. Bayesian Cox models were used to combine expert knowledge and ADNI data to predict dementia progression in people with MCI. Posterior distributions were obtained based on Gibbs sampler and the predictive performance was evaluated using ten-fold cross-validation via c-index, integrated calibration index (ICI), and integrated brier score (IBS). RESULTS: 365 people with MCI were included, mean age was 73 years (SD = 7.5), and 39% developed dementia within 3 years. When expert knowledge was incorporated, the c-index, ICI, and IBS values were 0.74 (95% CI 0.70-0.79), 0.06 (95% CI 0.05-0.08), and 0.17 (95% CI 0.14-0.19), respectively. These were similar to the model without expert knowledge data. CONCLUSION: The addition of expert knowledge did not improve model accuracy in this ADNI sample to predict dementia progression in individuals with MCI.

Trends and correlates of concurrent opioid and benzodiazepine and/or gabapentinoid use among Ontario nursing home residents.

BACKGROUND: A concern with long-term opioid use is the increased risk arising when opioids are used concurrently with drugs that can potentiate their associated adverse effects. The drugs most often encountered are benzodiazepines (BZDs) and gabapentinoids. Our study objectives were to examine trends in the concurrent use of opioids and BZDs, or gabapentinoids, in a Canadian nursing home population over an 11-year period, and current resident-level correlates of this concurrent use. METHODS: We conducted a population-based, repeated cross-sectional study among Ontario nursing home residents (>65 years) dispensed opioids between April 2009 and February 2020. For the last study year, we examined cross-sectional associations between resident characteristics and concurrent use of opioids with BZDs or gabapentinoids. Linked data on nursing home residents from clinical and health administrative databases was used. The yearly proportions of residents who were dispensed an opioid concurrently with a BZD or gabapentinoid were plotted with percent change derived from log-binomial regression models. Separate modified Poisson regression models estimated resident-level correlates of concurrent use of opioids with BZDs or gabapentinoids. RESULTS: Over the study period, among residents dispensed an opioid there was a 53.2% relative decrease (30.7% to 14.4%) in concurrent BZD and a 505.4% relative increase (4.4% to 26.6%) in concurrent gabapentinoid use. In adjusted models, increasing age and worsening cognition were inversely associated with the concurrent use of both classes, but most other significantly related covariates were unique to each drug class (e.g., sex and anxiety disorders for BZD, pain severity and presence of pain-related conditions for gabapentinoids). CONCLUSIONS: Co-administration of BZDs or gabapentinoids in Ontario nursing home residents dispensed opioids remains common, but the pattern of co-use has changed over time. Observed covariates of concurrent use in 2019/20 suggest distinct but overlapping resident populations requiring consideration of the relative risks versus benefits of this co-use and monitoring for potential harm.

Coping Behaviors and Health Status during the COVID-19 Pandemic among Caregivers of Assisted Living Residents in Western Canada.

OBJECTIVES: To examine the prevalence of coping behaviors during the first 2 waves of the COVID-19 pandemic among caregivers of assisted living residents and variation in these behaviors by caregiver gender and mental health. DESIGN: Cross-sectional and longitudinal survey. SETTING AND PARTICIPANTS: Family/friend caregivers of assisted living residents in Alberta and British Columbia. METHODS: A web-based survey, conducted twice (October 28, 2020 to March 31, 2021 and July 12, 2021 to September 7, 2021) on the same cohort obtained data on caregiver sociodemographic characteristics, anxiety and depressive symptoms, and coping behaviors [seeking counselling, starting a psychotropic drug (sedative, anxiolytic, antidepressant), starting or increasing alcohol, tobacco and/or cannabis consumption] during pandemic waves 1 and 2. Descriptive analyses and multivariable (modified) Poisson regression models identified caregiver correlates of each coping behavior. RESULTS: Among the 673 caregivers surveyed at baseline, most were women (77%), White (90%) and age ≥55 years (81%). Alcohol (16.5%) and psychotropic drug (13.3%) use were the most prevalent coping behaviors reported during the initial wave, followed by smoking and/or cannabis use (8.0%), and counseling (7.4%). Among the longitudinal sample (n = 386), only alcohol use showed a significantly lower prevalence during the second wave (11.7% vs 15.1%, P = .02). During both waves, coping behaviors did not vary significantly by gender, however, psychotropic drug and substance use were significantly more prevalent among caregivers with baseline anxiety and depressive symptoms, including in models adjusted for confounders [eg, anxiety: adjusted risk ratio = 3.87 (95% CI 2.50-6.00] for psychotropic use, 1.87 (1.28-2.73) for alcohol use, 2.21 (1.26-3.88) for smoking/cannabis use). CONCLUSIONS AND IMPLICATIONS: Assisted living caregivers experiencing anxiety or depressive symptoms during the pandemic were more likely to engage in drug and substance use, potentially maladaptive responses. Public health and assisted living home initiatives that identify caregiver mental health needs and provide targeted support during crises are required to mitigate declines in their health.

The Brain Medicine Fellowship: A Competency-Based Training Program to Treat Complex Brain Disorders.

PROBLEM: Complex brain disorders involve symptoms in the domains of affect, behavior, and cognition. It is increasingly recognized that there is a need for a novel type of physician who can treat individuals with these conditions in an interdisciplinary fashion to best address their complexity. Few training programs have focused on the education of such practitioners. APPROACH: The authors outline the development and practices of the Brain Medicine Fellowship, an innovative, competency-based fellowship program at the University of Toronto Temerty Faculty of Medicine that accepts trainees from multiple brain medicine-related specialty training programs to develop expertise in integrative assessment and treatment of complex brain disorders. The authors describe how brain medicine competencies were generated, the current assessment process, and the seminal clinical experience associated with the fellowship-the Brain Medicine Clinic-and explain how it exemplifies brain medicine in action. OUTCOMES: The first fellow was registered from July 2019 to December 2020. As of December 2022, 3 fellows have entered the program, with 3 more anticipated to begin in July 2023. More than 26 supervisors are associated with the fellowship, who offer a diversity of experiences for fellows to choose from in developing their individualized learning plans. The Brain Medicine Fellowship not only fosters the development of a novel type of clinician (a brain medicine specialist) but also is innovative in its educational design as one of the first nonsurgical fellowships to implement competency-based medical education and has resulted in original clinical programming in the form of the Brain Medicine Clinic, which benefits patients and their caregivers. NEXT STEPS: The development of the Brain Medicine Fellowship continues with competency refinement and translation into entrustable professional activities and constituent milestones. A comprehensive program evaluation will be completed by 2025.

Frailty and the impacts of the COVID-19 pandemic on community-living middle-aged and older adults: an analysis of data from the Canadian Longitudinal Study on Aging (CLSA).

BACKGROUND: frailty imparts a higher risk for hospitalisation, mortality and morbidity due to COVID-19 infection, but the broader impacts of the pandemic and associated public health measures on community-living people with frailty are less known. METHODS: we used cross-sectional data from 23,974 Canadian Longitudinal Study on Aging participants who completed a COVID-19 interview (Sept-Dec 2020). Participants were included regardless of whether they had COVID-19 or not. They were asked about health, resource, relationship and health care access impacts experienced during the pandemic. Unadjusted and adjusted prevalence of impacts was estimated by frailty index quartile. We further examined if the relationship with frailty was modified by sex, age or household income. RESULTS: community-living adults (50-90 years) with greater pre-pandemic frailty reported more negative impacts during the first year of the pandemic. The frailty gradient was not explained by socio-demographic or health behaviour factors. The largest absolute difference in adjusted prevalence between the most and least frail quartiles was 15.1% (challenges accessing healthcare), 13.3% (being ill) and 7.4% (increased verbal/physical conflict). The association between frailty and healthcare access differed by age where the youngest age group tended to experience the most challenges, especially for those categorised as most frail. CONCLUSION: although frailty has been endorsed as a tool to inform estimates of COVID-19 risk, our data suggest it may have a broader role in primary care and public health by identifying people who may benefit from interventions to reduce health and social impacts of COVID-19 and future pandemics.

Healthcare provider and patient/family perceptions of continuous pressure imaging technology for prevention of pressure injuries: A secondary analysis of patients enrolled in a randomized control trial.

INTRODUCTION: Despite the availability of various pressure injury (PI) prevention strategies (e.g., risk identification, use of pressure re-distribution surfaces, frequent repositioning), they persist as a significant issue for healthcare systems worldwide. Continuous pressure imaging (CPI) is a novel technology that could be integrated within a comprehensive approach to the prevention of PIs. We studied the perceptions of healthcare providers and patients/families to identify facilitators and barriers to the use of this technology. METHODS: Hospitalized patients/family members from a randomized controlled trial assessing the efficacy of CPI in preventing PIs completed a survey after 72 hours (or upon discharge from hospital) of CPI monitoring. They were asked questions about prior and current experience with CPI technology. For healthcare providers, perceptions on the use of the device and its impact on care were explored through a survey distributed by email or hard copies. RESULTS: A total of 125 healthcare providers and 525 patients/family members completed the surveys. Of the healthcare providers, 95% either agreed/strongly agreed that the CPI technology was easy to use and 65% stated that the device improved how they provided pressure relief for patients. Identified issues with the device were cost, the fitting of the mattress cover, and the fixation of the patients/families on the device. Over a quarter of the patient/family respondents agreed/strongly agreed that the device influenced how pressure relief was provided. This response was statistically associated with whether the monitor was turned on (intervention arm; 52.7%) or off (control arm; 4.2%). DISCUSSION AND CONCLUSION: CPI technology was positively perceived by healthcare providers. Most patients/families felt it influenced care when the CPI monitor was turned on. Concerns raised around cost and the ease of use of these devices by healthcare providers may affect the decisions of healthcare system administrators to adopt and implement this technology.

An environmental scan of methods for assessing age-friendliness in post-secondary institutions.

The University of Calgary joined the Age-Friendly University (AFU) Global Network in 2018. As part of our university's AFU action plan, a baseline assessment of the institution's age-friendliness will be conducted to identify areas of strength and growth. To inform our approach and that of other institutions undertaking this work, an environmental scan was performed to determine methods used by post-secondary institutions to date to assess age-friendliness. Both academic and grey literature published between 2012 and 2022 in the English language was searched using diverse keywords. The academic literature was identified from four databases (Abstracts in Social Gerontology, Academic Search Complete, Education Research Complete, Scopus) and the grey literature from 84 institutional websites of AFU Global Network members. Twelve academic sources and four grey sources were included in the analysis. Seven methods were used to assess age-friendliness, with the most common approaches being surveys, inventories, focus groups, interviews, and photovoice. The Age-Friendly Inventory and Campus Climate Survey (Silverstein et al., 2022) was selected to evaluate the University of Calgary's age-friendliness due to its alignment with all 10 AFU principles, comprehensiveness, and involvement of multiple stakeholders. Other post-secondary institutions should consider their context and resources when selecting an assessment method.
