myHealthHub for older adult inpatients to reduce loneliness, and improve patient engagement and mental health: protocol of a pilot randomized controlled trial.

OBJECTIVES: Older Canadian adults make up 85% of hospital stays which are associated with increased loneliness, stress, anxiety, and/or depression. There is a need for novel approaches to reduce loneliness and mental health outcomes in older adult hospital inpatients to prevent further strain on an already overwhelmed healthcare system. METHODS: This is a pilot randomized controlled trial (RCT) exploring the efficacy of a bedside multimodal interaction system, myHealthHub, on loneliness, quality of life (QOL), patient engagement, and other mental health outcomes compared to an active control group in older adult inpatients (n = 60) from baseline to 5-days. Qualitative analyses will be conducted through semi-structured interviews with older adults (n = 8-10) and hospital staff, nurses, and clinicians (n = 4-5) facilitating the service to evaluate patient engagement and experience with myHealthHub. RESULTS: Not applicable. CONCLUSION: This novel pilot clinical trial will obtain preliminary data on the efficacy of myHealthHub in reducing loneliness, QOL, patient engagement, and mental health outcomes in older adult inpatients. If successful, this could provide a potential means to improve patient experience in hospitals and reduce the burden and additional expense on the healthcare system.

A Decision-Making Algorithm for Remote Digital Assessments of Alzheimer's Disease.

INTRODUCTION: Remote digital assessments (RDAs) such as voice recording, video and motor sensors, olfactory, hearing, and vision screenings are now starting to be employed to complement classical biomarker and clinical evidence to identify patients in the early AD stages. Choosing which RDA can be proposed to individual patients is not trivial and often time-consuming. This position paper presents a decision-making algorithm for using RDA during teleconsultations in memory clinic settings. METHOD: The algorithm was developed by an expert panel following the Delphi methodology. RESULTS: The decision-making algorithm is structured as a series of yes-no questions. The resulting questionnaire is freely available online. DISCUSSION: We suggest that the use of screening questionnaires in the context of memory clinics may help accelerating the adoption of RDA in everyday clinical practice.

"Emergency Room Evaluation and Recommendations" and Incident Hospital Admissions in Older People with Major Neurocognitive Disorders Visiting Emergency Department: Results of an Experimental Study.

INTRODUCTION: Older people with major neurocognitive disorders (MNCDs) visiting the emergency department (ED) are at high risk of hospital admissions. The "Emergency Room Evaluation and Recommendations" (ER2) tool decreases the length of stay (LOS) in the hospital when older people visiting ED are hospitalized after an index ED visit, regardless of their cognitive status. Its effect on hospital admissions has not yet been examined in older people with MNCD visiting ED. This study aimed to examine whether ER2 recommendations were associated with incident hospital admissions and LOS in ED in older people with MNCD visiting ED. METHODS: A total of 356 older people with MNCD visiting ED of the Jewish General Hospital (Montreal, Quebec, Canada) were recruited in this non-randomized, pre-post-intervention, single arm, prospective and longitudinal open label trial. ED staff and patients were blinded of the ER2 score, and patients received usual ED care during the observation period, whereas ED staff were informed about the ER2 score, and patients had ER2 tailor-made recommendations in addition to usual care during the intervention period. Hospital admissions and the LOS in ED were the outcomes. RESULTS: There were less incident hospital admissions (odds ratio ≤ 0.61 with p ≤ 0.022) and longer LOS in ED (coefficient beta ≥4.28 with p ≤ 0.008) during the intervention period compared to the observation period. DISCUSSION/CONCLUSION: ER2 recommendations have mixed effects in people with MNCD visiting ED. They were associated with reduced incident hospital admissions and increased LOS in ED, suggesting that they may have benefits in addition to usual ED care.

Improving the mental and physical health of older community-dwellers with a museum participatory art-based activity: results of a multicentre randomized controlled trial.

BACKGROUND: The aim of this randomized controlled trial (RCT) was to examine the mental and physical effects of a participatory art-based activity carried out at museums in older community-dwellers. METHODS: Based on a bicentre (the Montreal Museum of Fine Arts (MMFA), Montreal, Quebec, Canada; the Fuji Museum, Tokyo, Japan) single-blind RCT in two parallel groups (intervention group versus control group), 228 community-dwelling older adults (mean age 71.1 ± 5.4 years, 76.3% female) were enrolled. The intervention was a participatory art-based activity carried out at the MMFA and the Fuji Museum. The intervention group met weekly for 2 h over a 12-week period. The control group did not participate in any art-based intervention over the study period. Well-being was assessed before and after the first (M0) and the twelfth (M3) workshops, and quality of life and frailty before workshops at M0 and M3. These outcomes were assessed with standardized questionnaires with the same schedule in both groups. RESULTS: Well-being and quality of life improved significantly in the intervention group compared to the control group. Mixed results were observed with frailty. Although there were significantly more vigorous and fewer mildly frail participants by the end of the session when comparing intervention to control group participants, only a trend was observed in the decrease in mean value of the intervention group's frailty score. INTERPRETATION: This RCT confirmed that a participatory art-based activity performed weekly over a 3-month period may improve both mental and physical health in older community-dwellers. TRIAL REGISTRATION: NCT03679715; Title: A-Health RCT: Effects of Participatory Art-Based Activity on Health of Older Community Dwellers; First posted date: September 20, 2018; prospectively registered: https://clinicaltrials.gov/ct2/show/NCT03679715.

Implementing a Telehealth Support Tool for Community-Dwelling Older Adults During the COVID-19 Pandemic: A Qualitative Investigation of Provider Experiences.

During the COVID-19 pandemic, policymakers had to quickly offer telehealth services to address older adults' needs. This study aimed to understand the experiences of providers who implemented a telephone-based telehealth tool named Socio-Geriatric Evaluation (ESOGER), which assessed health and social isolation risks in community-dwelling older adults in Quebec (Canada). This qualitative study used 20 semi-structured online/phone interviews with health and social service providers coming from publicly-funded healthcare facilities and community organizations. We included adopters and non-adopters of the telehealth tool. Interviews were audio-recorded and transcribed verbatim. We used reflexive thematic analysis to interpret the data. Three dimensions of providers' practice influenced the tool's implementation: service organization, working conditions, and interactions with older adults. Participants reported that the tool fostered continuity of care, provided guidance for their pandemic-related new tasks, and helped identify and support socially isolated older adults. Challenges to implementation included limited appropriateness of the telehealth tool for diverse services, feasibility barriers to adopting a new tool amid the health crisis, and acceptability challenges with some older adults. Despite relevance of the telehealth tool for providers, organizational, professional, and interactional barriers could hinder implementation success. Participatory approaches to telehealth may be promising avenues for future policies in this field.

Motoric cognitive risk syndrome and incident dementia in older adults from the Québec NuAge cohort.

BACKGROUND: The co-occurrence of slow walking speed and subjective cognitive complaint (SCC) in non-demented individuals defines motoric cognitive risk syndrome (MCR), which is a pre-dementia stage. There is no information on the association between MCR and incident dementia in Québec's older population. OBJECTIVE: The study aims to examine the association of MCR and its individual components (i.e. SCC and slow walking speed) with incident dementia in community-dwelling older adults living in the province of Québec (Canada). DESIGN: Québec older people population-based observational cohort study with 3 years of follow-up. SETTING: Community dwellings. SUBJECTS: A subset of participants (n = 1,098) in 'Nutrition as a determinant of successful aging: The Québec longitudinal study' (NuAge). METHODS: At baseline, participants with MCR were identified. Incident dementia was measured at annual follow-up visits using the Modified Mini-Mental State (≤79/100) test and Instrumental Activity Daily Living scale (≤6/8) score values. RESULTS: The prevalence of MCR was 4.2% at baseline and the overall incidence of dementia was 3.6%. MCR (Hazard Ratio (HR) = 5.18, with 95% confidence interval (CI) = [2.43-11.03] and P ≤ 0.001) and SCC alone (HR = 2.54, with 95% CI = [1.33-4.85] and P = 0.005) were associated with incident dementia, but slow walking speed was not (HR = 0.81, with 95%CI = [0.25-2.63] and P = 0.736). CONCLUSIONS: MCR and SCC are associated with incident dementia in NuAge study participants.

Prognosis tools for short-term adverse events in older emergency department users: result of a Québec observational prospective cohort.

BACKGROUND: The "Program of Research on the Integration of Services for the Maintenance of Autonomy" (PRISMA-7) and "Emergency room evaluation and recommendations" (ER2) are both clinical tools used in Québec Emergency Departments (EDs) for screening of older ED users at higher risk of poor outcomes, such as prolonged length of stay (LOS) in EDs and in hospital. The study aimed to: 1) examine whether the PRISMA-7 and ER2 risk levels were associated with length of stays in ED and hospital, as well as hospital admission; and 2) compare the criteria performance (i.e., sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratios and area under receiver operating characteristic curve) of the PRISMA-7 and ER2 high-risk levels for these three ED adverse events in Québec older patients visiting ED on a stretcher. METHODS: A total of 1905 older patients who visited the ED of the Jewish General Hospital (Montreal, Québec, Canada) on stretchers were recruited in this prospective observational cohort. Upon their ED arrival, PRISMA-7 and ER2 were performed. The outcomes were LOS in ED and in hospital, and hospital admission. RESULTS: The PRISMA-7 and ER2 risk levels were associated with length of stay in ED and hospital as well as with hospital admission. Prolonged stays and higher hospitalization rates were associated with high-risk levels, whereas those in low-risk level groups had significantly shorter LOS and a lower rate of hospital admission (P < 0.006). While performance measures were poor for both assessment tools, ER2 had a greater prognostic testing accuracy compared with PRISMA-7. CONCLUSION: PRISMA-7 and ER2 were both associated with incidental short-term ED adverse events but their overall prognostic testing accuracy was low, suggesting that they cannot be used as prognostic tools for this purpose.

Effects of participatory art-based painting workshops in geriatric inpatients: results of a non-randomized open label trial.

BACKGROUND: Art-based activities like painting workshops demonstrated health benefits in older individuals living in home care facilities. Few studies examined the effects of painting workshops in geriatric inpatients. AIM: The study aims to examine whether the participation in painting workshops performed in patients admitted to a geriatric acute care ward reduced the number of medications taken daily, use of psychoactive medications, the length of stay and inhospital mortality. METHODS: Based on a non-randomized open label trial, 79 inpatients who participated in painting workshops and 79 control inpatients were recruited in the geriatric acute care ward of the Jewish general hospital (Montreal, Quebec, Canada). Four outcomes were used: the number of medications taken daily and use of psychoactive medications the day of discharge to geriatric acute care ward, the length of hospital stay and inhospital mortality. RESULTS: The participation in Painting workshops were associated with a lower number of medications taken daily at discharge (Coefficient of regression ß = - 1.35 with P = 0.001) and lower inhospital mortality (odd ratio (OR) = 0.09 with P = 0.031). No significant association was reported with use of psychoactive medications and length of stay. CONCLUSION: The participation in painting workshops reduced the number of medications taken daily and incident inhospital mortality in geriatric inpatients admitted to a geriatric acute care ward, suggested a positive effect on health condition of this participatory art-based activity.

Screening for older inpatients at risk for long length of stay: which clinical tool to use?

BACKGROUND: Screening for inpatients at risk for long length of stay (LOS) is the first step of an effective hospital care plan for older inpatients. This study aims, in older adults admitted to a geriatric acute care ward, to examine and compare the 6-item brief geriatric assessment (BGA) and the "Programme de Recherche sur l'Intégration des Services pour le Maintien de l'Autonomie" (PRISMA-7) risk levels with long LOS, and to establish their performance criteria (i.e., sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratios) for LOS. METHODS: Based on an observational, retrospective, cohort design, 166 inpatients aged ≥75 admitted to a geriatric acute care ward of a McGill University-affiliated hospital (Montreal, Quebec, Canada) were recruited. The risk levels of the 6-item BGA (low, moderate and high) and the PRISMA-7 (low versus high) were calculated from a baseline assessment. The LOS was subsequently calculated in number of days. RESULTS: Only the 6-item BGA high risk level was associated with a long LOS (Odds ratio = 1.1 with P = 0.028 and Hazard ratio = 2.1 with P = 0.004). Kaplan-Meier distributions showed that there was no significant difference in the delay of hospital discharge between the low and high-risk level reported by the PRISMA-7 (P = 0.381), whereas the 6-item BGA three risk levels differed significantly (P = 0.008), with individuals at high risk levels being discharged later when compared to those with low (P = 0.001) and moderate (P = 0.019) risk levels. Both tools' performance criteria were poor (i.e., < 0.70), except for PRISMA-7's sensitivity which was 100%. CONCLUSION: The 6-item BGA risk levels were associated with LOS, low risk-level being associated with short LOS and high-risk level with long LOS, but no association was reported with the PRISMA-7 risk levels. Both tools had poor performance criteria for long LOS, suggesting that they cannot be used as prognostic tools with current scientific knowledge.

In 2018, new recommendations about the prevention of falls and fractures emphasized the benefits from exercise and from multimodal prevention programs but did not endorse any more vitamin D supplementation for falls prevention. Results were contrasted for several studies testing exercise (negative) and cognitive training (mixed results) in the management of older patients suffering from neurocognitive disorders. The new direct oral anticoagulants are increasingly prescribed in older patients despite the paucity of data. New information has been released in 2018 from « real-world ¼ data that seem reassuring about their risk/benefit ratio in old-old patients, provided a careful prescription. Finally, the Mediterranean diet is still gaining credit with a new study showing its benefits in preventing frailty in community-dwelling older persons.

En 2018, l'intérêt de l'activité physique et des programmes de prévention multimodaux est confirmé pour la prévention des chutes, mais l'utilisation de la vitamine D dans cette indication est remise en question. Pour les pathologies neurocognitives, les résultats sont contrastés concernant l'activité physique, alors qu'une revue systématique confirme les bénéfices, certes modestes, de l'entraînement cognitif sur les performances cognitives et la qualité de vie des patients et de leurs proches. Les nouveaux anticoagulants sont de plus en plus largement utilisés chez les patients âgés malgré des données encore limitées, mais plusieurs études du « monde réel ¼ semblent confirmer leur bon rapport risques/bénéfices aussi chez ces patients. Le régime méditerranéen a le vent en poupe, une étude rapporte un bénéfice sur l'incidence de la fragilité.

Association Between Falls and Brain Subvolumes: Results from a Cross-Sectional Analysis in Healthy Older Adults.

Falls are a consequence of gait instability. Cortical and subcortical abnormalities have been associated with gait instability but not yet with falls. This study aims to compare the global and regional brain subvolumes between healthy older fallers and non-fallers. A total of 77 healthy older individuals (23 fallers and 54 non-fallers, 69.8 ± 3.5 years; 45.5 % female) were included in this study using a cross-sectional design. Based on an a priori hypothesis, the following brain subvolumes were quantified from three-dimensional T1-weighted MRI using FreeSurfer software: total white matter abnormalities, total white matter, total cortical and subcortical gray matter, hippocampus, motor cortex, somatosensory cortex, premotor cortex, prefrontal cortex and parietal cortex volumes. Gait performances were also recorded. Age, sex, body mass index, comorbidities, use of psychoactive drugs, far-distance visual acuity, lower-limb proprioception, depressive symptoms and cognitive scores (Mini-Mental State Examination, Frontal Assessment Battery) were used as covariates. Fallers have more frequently depressive symptoms (P = 0.048), a lower far distance visual acuity (P = 0.026) and a higher coefficient of variation of stride time (P = 0.008) compared to non-fallers. There was a trend to greater subvolumes for the somatosensory cortex (P = 0.093) and the hippocampus (P = 0.060) in the falls group. Multiple logistic regressions showed that subvolumes of the somatosensory cortex and the hippocampus (P < 0.042) were increased in fallers compared to non-fallers, even after adjustment for clinical and brain characteristics. The greater subvolumes of the somatosensory cortex and hippocampus reported in fallers compared to non-fallers suggests a possible brain compensatory mechanism involving spatial navigation and integration of sensory information.

In 2016, consequences, contributing factors, and prevention of inappropriate drug prescribing were investigated. Two studies lift the veil on unexplained falls and syncope. A meta-analysis questions the need to adapting transfusion's threshold to comorbidities, and another one the performance of screening for swallowing disorders. The Framingham Heart Study reports the declining of the incidence of vascular dementia. The role played by microbleeds in cognitive deterioration was investigated and aducanumab showed encouraging effect in Alzheimer's disease. When vaccination against influenza for health workers in nursing home was challenged by a meta-analysis this recommendation must be followed. Vaccines against shingles are effective and safe, and a study confirms the efficacy of the HZ7su among 70+.

En 2016, les conséquences, les facteurs favorisants et la prévention des prescriptions médicamenteuses inappropriées ont été étudiés. Deux études lèvent le voile sur les chutes inexpliquées et les syncopes. Une méta-analyse questionne sur l'adaptation du seuil transfusionnel aux comorbidités et une autre le dépistage des troubles de la déglutition. L'étude de Framingham rapporte la diminution de l'incidence des démences vasculaires. Le rôle joué par les microbleeds dans la détérioration cognitive a été exploré et l'aducanumab montre des effets encourageant dans la maladie d'Alzheimer. Si la vaccination contre la grippe du personnel d'EMS est remise en question par une méta-analyse, cette recommandation doit être respectée. Les vaccins contre le zona sont efficaces et sûrs et une étude confirme l'efficacité du HZ / su chez les plus de 70 ans.

Motor imagery of gait: a new way to detect mild cognitive impairment?

OBJECTIVES: 1) To measure and compare the time required to perform (pTUG) and the time required to imagine (iTUG) the Timed Up & Go (TUG), and the time difference between these two tasks (i.e., TUG delta time) in older adults with cognitive decline (i.e., mild cognitive impairment (MCI) and mild-to-moderate Alzheimer disease and related disorders (ADRD)) and in cognitively healthy individuals (CHI); and 2) to examine any association between the TUG delta time and a cognitive status. METHODS: Sixty-six participants (24 CHI, 23 individuals with MCI, and 19 individuals with ADRD) were recruited in this cross-sectional study. The mean and standard deviation of the pTUG and iTUG completion times and the TUG delta time, as well as age, gender, and Mini-Mental State Examination (MMSE) scores were used as outcomes. Participants were separated into three groups based on the tertilization of TUG delta time: lowest (<13.6%; n = 22; best performance), intermediate (13.6-52.2%; n = 22), and highest tertile (>52.2%; n = 22, worst performance). RESULTS: Fewer CHI were in the group exhibiting the highest tertile of TUG delta time compared to individuals with lowest and intermediate TUG delta times (p = 0.013). Being in the highest tertile of the TUG delta time was associated with cognitive decline in the unadjusted model (p = 0.012 for MCI, and p = 0.021 for mild-to-moderate ADRD). In the multivariate models, this association remained significant only for individuals with MCI (p = 0.019 while adjusting for age and gender; p = 0.047 while adjusting for age, gender, and MMSE score; p = 0.012 for the stepwise backward model). CONCLUSIONS: Our results provide the first evidence that motor imagery of gait may be used as a biomarker of MCI in older adults.

The influence of fear of falling on gait variability: results from a large elderly population-based cross-sectional study.

OBJECTIVE: To compare gait variability among older community-dwellers with and without fear of falling and history of falls, and 2) to examine the association between gait variability and fear of falling while taking into account the effect of potential confounders. METHODS: Based on a cross-sectional design, 1,023 French community-dwellers (mean age ± SD, 70.5 ± 5.0 years; 50.7% women) were included in this study. The primary endpoints were fear of falling, stride-to-stride variability of stride time and walking speed measured using GAITRite® system. Age, gender, history of falls, number of drugs daily taken per day, body mass index, lower-limb proprioception, visual acuity, use of psychoactive drugs and cognitive impairment were used as covariables in the statistical analysis. P-values less than 0.05 were considered as statistically significant. RESULTS: A total of 60.5% (n=619) participants were non-fallers without fear of falling, 19% (n=194) fallers without fear of falling, 9.9% (n=101) non-fallers with fear of falling, and 10.7% (n=109) fallers with fear of falling. Stride-to-stride variability of stride time was significantly higher in fallers with fear of falling compared to non-fallers without fear of falling. Full adjusted linear regression models showed that only lower walking speed value was associated to an increase in stride-to-stride variability of stride time and not fear of falling, falls or their combination. While using a walking speed ≥ 1.14 m/s (i.e., level of walking speed that did not influence stride-to-stride variability of stride time), age and combination of fear of falling with history of previous falls were significantly associated with an increased stride-to-stride variability of stride time. CONCLUSIONS: The findings show that the combination of fear of falling with falls increased stride-to-stride variability of stride time. However, the effect of this combination depended on the level of walking speed, increase in stride-to-stride variability of stride time at lower walking speed being related to a biomechanical effect overriding fear of falling-related effects.

Prioritizing Protecting Oneself Over the COVID-19 Virus Versus Other Health and Social Needs Among Older Adults Living Alone: A Qualitative Study.

BACKGROUND AND OBJECTIVES: People aged 65 and older, deemed most "vulnerable" by public health, were targeted by the coronavirus disease 2019 protection measures, which sought to minimize physical contact and social activities. Older adults living alone were particularly affected by these measures. However, such measures meant to protect the older population may not have necessarily reflected older adults' individual prioritization choices. This study therefore aimed to understand how protecting oneself over the virus was considered in the prioritization of other health and social needs of older adults living alone during the pandemic. RESEARCH DESIGN AND METHODS: This study adopted a qualitative design. A total of 17 semistructured interviews were conducted between May 2021 and June 2022 with older adults living alone. All interviews were audio-recorded and transcribed verbatim. A reflexive thematic analysis as defined by Braun and Clarke was performed. RESULTS: Our analysis showed 2 forms of prioritization across 2 themes. This first theme focused on participants who reported prioritizing protecting themselves over the virus by limiting in-person contact and activities. The second theme showed that although several participants reported that protecting themselves over the virus was important to them, the prioritization of this need was not shared by all and, in some cases, evolved over the course of the pandemic. DISCUSSION AND IMPLICATIONS: Our study demonstrated heterogeneity in the prioritization of older adults needs. Future public health recommendations should consider these variations in the needs and priorities of older adults when determining public health measures.

Anti-dementia drugs and changes in gait: a pre-post quasi-experimental pilot study.

BACKGROUND: Anti-dementia drugs may improve gait performance. No comparison between acetylcholinesterase inhibitors (CEIs) and memantine-related changes in gait variability has been reported. The objectives of this study were to 1) quantify and compare the mean values and coefficients of variation (CoV) of stride time in demented patients with Alzheimer's disease and related disorders (ADRD) before and after the use of CEIs or memantine, and in age- and gender-matched controls patients with ADRD using no anti-dementia drugs; and 2) to determine whether changes in CoV of stride time differed between CEIs or memantine. METHODS: A total of 120 demented patients with mild-to-moderate ADRD were prospectively included in this pre-post quasi-experimental study with two intervention groups (43 patients taking CEIs, and 41 taking memantine) and a control group (36 age- and gender matched patients without any anti-dementia drugs). CoV of stride time and walking speed were measured with GAITRite® system while usual walking at steady state. Age, gender, number of drugs daily taken, use of psychoactive drugs, body mass index and time between the two visits were also recorded. RESULTS: There was no difference between groups for the time between baseline and follow-up assessments (232.9 ± 103.7 days for patients without anti-dementia drugs, 220.0 ± 67.5 days for patients with CEIs, 186.7 ± 96.2 days for patients with memantine, P = 0.062). Patients with memantine had a lower (i.e., better) CoV of stride time at follow-up assessment compared to those with CEIs (4.2 ± 2.4% versus 5.8 ± 4.2%, P = 0.010). Patients with memantine had a greater decrease in CoV of stride time compared to those with CEIs (-1.90% versus 0.93%, P = 0.010) and mixed-effects linear regressions showed that this decrease was specifically explained by memantine (P = 0.028). CONCLUSIONS: Our results showed that patients with ADRD and treated with memantine, but not those with CEIs, decreased their gait variability, and thus improved their gait safety (Trial registration number: NCT01315704).

Association between vitamin D deficiency and long hospital stay in geriatric acute care unit: results from a pilot cohort study.

Finding a biomarker of long length-of-stay (LOS) would provide a simple solution to target frail older inpatients at such risk. The aim of this study was to determine whether serum 25-hydroxyvitamin D (25OHD) deficiency, defined as serum concentration <25 nmol/L, was associated with long LOS among inpatients admitted to a geriatric acute care unit. Three hundred and six older inpatients (mean age 84.6 ± 6.4 years, 61.8% women) were consecutively included in this longitudinal prospective cohort study. Patients were separated into two groups according to LOS tertiles: highest tertile (≥14 days; n = 120) versus the other two tertiles combined (<14 days; n = 186). Serum 25OHD deficiency (58.3 vs. 38.7%, P = 0.001) and the prevalence of male gender (58.3 vs. 28.5%, P < 0.001) were higher among inpatients with the highest LOS compared with those with lower LOS. Serum 25OHD deficiency [odds ratio (OR) = 2.22, P = 0.001 for unadjusted model; OR = 1.87, P = 0.012 for fully adjusted model) and male gender (OR = 2.87, P < 0.001 for unadjusted model; OR = 2.64, P = 0.001 for full model) were associated with a high LOS. Vitamin D deficiency and male gender were risk factors for a long LOS in this pilot study. Using these risk factors to identify inpatients at risk of long LOS may be helpful in adapting early care plans, and thus improving inpatients' health and shortening LOS.

Screening for elderly patients admitted to the emergency department requiring specialized geriatric care.

BACKGROUND: There is a need for a brief geriatric assessment (BGA) tool to screen elderly patients admitted to the Emergency Department (ED) for their risk of a long hospital stay. OBJECTIVE: To examine whether a BGA administered to elderly patients admitted to the ED may predict the risk of a long hospital stay in the geriatric acute care unit. METHODS: This study had a prospective cohort study design, enrolling 424 elderly patients (mean age 84.0 ± 6.5 years, 31.6% male) who were evaluated in the ED using a BGA composed of the following items: age, gender, number of medications taken daily, history of falls during the past 6 months, Mini-Mental State Examination (MMSE) score, and non-use of home-help services (i.e., living alone without using any formal or informal home services or social help). The length of stay (LOS) was calculated in days. Patients were separated into three groups based on LOS: low (<8 days), intermediate (8-13 days), and high (>13 days). RESULTS: The prevalence of male gender was higher among patients with the longest LOS compared to those with intermediate LOS (p = 0.002). There were more patients with a history of falls in the high LOS group compared to the intermediate LOS group (p = 0.001) and the low LOS group (p < 0.001). The classification tree showed that male patients with an MMSE score <20 who fell with age under 85 years formed the end node with the greatest relative risk (RR) of a long hospital stay (RR = 14.3 with p < 0.001). CONCLUSIONS: The combination of a history of falls, male gender, cognitive impairment, and age under 85 years identified elderly ED patients at high risk of a long hospital stay.

Alzheimer's early detection in post-acute COVID-19 syndrome: a systematic review and expert consensus on preclinical assessments.

Introduction: The risk of developing Alzheimer's disease (AD) in older adults increasingly is being discussed in the literature on Post-Acute COVID-19 Syndrome (PACS). Remote digital Assessments for Preclinical AD (RAPAs) are becoming more important in screening for early AD, and should always be available for PACS patients, especially for patients at risk of AD. This systematic review examines the potential for using RAPA to identify impairments in PACS patients, scrutinizes the supporting evidence, and describes the recommendations of experts regarding their use. Methods: We conducted a thorough search using the PubMed and Embase databases. Systematic reviews (with or without meta-analysis), narrative reviews, and observational studies that assessed patients with PACS on specific RAPAs were included. The RAPAs that were identified looked for impairments in olfactory, eye-tracking, graphical, speech and language, central auditory, or spatial navigation abilities. The recommendations' final grades were determined by evaluating the strength of the evidence and by having a consensus discussion about the results of the Delphi rounds among an international Delphi consensus panel called IMPACT, sponsored by the French National Research Agency. The consensus panel included 11 international experts from France, Switzerland, and Canada. Results: Based on the available evidence, olfaction is the most long-lasting impairment found in PACS patients. However, while olfaction is the most prevalent impairment, expert consensus statements recommend that AD olfactory screening should not be used on patients with a history of PACS at this point in time. Experts recommend that olfactory screenings can only be recommended once those under study have reported full recovery. This is particularly important for the deployment of the olfactory identification subdimension. The expert assessment that more long-term studies are needed after a period of full recovery, suggests that this consensus statement requires an update in a few years. Conclusion: Based on available evidence, olfaction could be long-lasting in PACS patients. However, according to expert consensus statements, AD olfactory screening is not recommended for patients with a history of PACS until complete recovery has been confirmed in the literature, particularly for the identification sub-dimension. This consensus statement may require an update in a few years.

Profiles of socially isolated community-dwelling older adults during the COVID-19 pandemic: A latent class analysis.

OBJECTIVE: To identify different profiles of socially isolated older adults during the first wave of COVID-19 in Quebec, Canada. STUDY DESIGN: Cross-sectional data were obtained through a telehealth socio-geriatric risk assessment tool, ESOGER, administered to adults aged 70 years or more between April and July 2020 in Montreal, Canada. MEASURES: Those living alone with no social contacts in the last few days were considered socially isolated. Latent class analysis was performed to identify profiles of socially isolated older adults based on: age, sex, polypharmacy, use of home care, use of a walking aid, recall of current year/month, anxiety level (scale 0-10), and need for follow-up from a healthcare provider. RESULTS: Three-hundred and eighty (380) older adults identified as socially isolated were analyzed, of whom 75.5 % were female and 56.6 % were over 85. Three classes were identified: Class 1 ("physically frail older females") had the highest proportion of polypharmacy, walking aid, and home care use. Class 2 ("anxious, relatively younger males") were predominantly males who used the least home care but had the highest anxiety levels. Class 3 ("seemingly well older females") had the highest proportion of females, lowest proportion of polypharmacy, lowest anxiety level, and none used a walking aid. Recall of current year/month was similar across the three classes. CONCLUSIONS: This study found heterogeneity among socially isolated older adults during the first wave of the COVID-19 pandemic with varying levels of physical and mental health. Our findings may contribute to the development of targeted interventions to support this vulnerable population during and after the pandemic.
