Home-based rehabilitation following inpatient rehabilitation: Utilization rate and characteristics of referred patients.

OBJECTIVE: To determine the utilization rate of a home-based rehabilitation program following an inpatient rehabilitation stay, and to investigate the profile of users. DESIGN: Observational study SETTING: Inpatient rehabilitation facility in a tertiary hospital PARTICIPANTS: Older patients (N=1,913) discharged home between June 2018 and May 2021, after an inpatient rehabilitation stay. INTERVENTION: N/A MAIN OUTCOME MEASURE: Discharge to home-based rehabilitation RESULTS: Over the study period, 296 (15.5%) patients were discharged to home-based rehabilitation. Compared to the others, home-based rehabilitation patients were more frequently women (69.6% vs 61.5%, p=.008), and admitted after orthopedic surgery (elective or for fracture) (30.1% vs 16.1%, p<.001). They had worse functional performance at admission (mean FIM self-care score: 27.8±7.3 vs 30.8±6.7, p<.001), but greater gain in self-care during their inpatient stay (5.0±4.8 vs 4.4±4.7, p=.038). In multivariable analysis, being a woman (adjOR 1.36; 95%CI 1.01-1.82, p=.040), being admitted after orthopedic surgery (adjOR 2.32; 95%CI 1.64-3.27, p<.001), being admitted for gait disorders or falls (adjOR 1.38; 95%CI 1.01-1.88, p=.039), and showing greater gain in mobility during the inpatient stay (adjOR 1.12; 95%CI 1.07-1.17, p<.001) remained associated with discharge to home-based rehabilitation. In contrast, higher mobility at discharge decreased the odds of discharge to home-based rehabilitation (adjOR 0.87; 95%CI 0.83-0.91, p<.001). CONCLUSION: One in six patients benefited from home-based rehabilitation after their inpatient stay. Although these patients had poorer functional performance at admission and discharge, they showed greater mobility improvement during their inpatient stay, suggesting that their good recovery potential was a key determinant of their orientation toward home-based rehabilitation.

Unplanned transfer to acute care during inpatient geriatric rehabilitation: incidence, risk factors, and associated short-term outcomes.

BACKGROUND: Information is scarce on unplanned transfers from geriatric rehabilitation back to acute care despite their potential impact on patients' functional recovery. This study aimed 1) to determine the incidence rate and causes of unplanned transfers; 2) to compare the characteristics and outcomes of patients with and without unplanned transfer. METHODS: Consecutive stays (n = 2375) in a tertiary geriatric rehabilitation unit were included. Unplanned transfers to acute care and their causes were analyzed from discharge summaries. Data on patients' socio-demographics, health, functional, and mental status; length of stay; discharge destination; and death, were extracted from the hospital database. Bi- and multi-variable analyses investigated the association between patients' characteristics and unplanned transfers. RESULTS: One in six (16.7%) rehabilitation stays was interrupted by a transfer, most often secondary to infections (19.3%), cardiac (16.8%), abdominal (12.7%), trauma (12.2%), and neurological problems (9.4%). Older patients (AdjORage≥85: 0.70; 95%CI: 0. 53-0.94, P = .016), and those admitted for gait disorders (AdjOR: 0.73; 95%CI: 0.53-0.99, P = .046) had lower odds of transfer to acute care. In contrast, men (AdjOR: 1.71; 95%CI: 1.29-2.26, P < .001), patients with more severe disease (AdjORCIRS: 1.05; 95%CI: 1.02-1.07, P < .001), functional impairment before (AdjOR: 1.69; 95%CI: 1.05-2.70, P = .029) and at rehabilitation admission (AdjOR: 2.07; 95%CI: 1.56- 2.76, P < .001) had higher odds of transfer. Transferred patients were significantly more likely to die than those without transfer (AdjOR 13.78; 95%CI: 6.46-29.42, P < .001) during their stay, but those surviving had similar functional performance and rate of home discharge at the end of the stay. CONCLUSION: A significant minority of patients experienced an unplanned transfer that potentially interfered with their rehabilitation and was associated with poorer outcomes. Men, patients with more severe disease and functional impairment appear at increased risk. Further studies should investigate whether interventions targeting these patients may prevent unplanned transfers and modify associated adverse outcomes.

Diabetes mellitus in older persons with neurocognitive disorder: overtreatment prevalence and associated structural brain MRI findings.

BACKGROUND: Tight diabetes control is often applied in older persons with neurocognitive disorder resulting in increased hypoglycemic episodes but little is known about the pattern of brain injury in these overtreated patients. This study aims to: (a) quantify the prevalence of diabetes overtreatment in cognitively impaired older adults in a clinical population followed in an academic memory clinic (b) identify risk factors contributing to overtreatment; and (c) explore the association between diabetes overtreatment and specific brain region volume changes. METHODS: Retrospective study of older patients with type 2 diabetes and cognitive impairment who were diagnosed in a memory clinic from 2013 to 2020. Patients were classified into vulnerable and dependent according to their health profile. Overtreatment was defined when glycated hemoglobin was under 7% for vulnerable and 7.6% for dependent patients. Characteristics associated to overtreatment were examined in multivariable analysis. Grey matter volume in defined brain regions was measured from MRI using voxel-based morphometry and compared in patients over- vs. adequately treated. RESULTS: Among 161 patients included (median age 76.8 years, range 60.8-93.3 years, 32.9% women), 29.8% were considered as adequately treated, 54.0% as overtreated, and 16.2% as undertreated. In multivariable analyses, no association was observed between diabetes overtreatment and age or the severity of cognitive impairment. Among patients with neuroimaging data (N = 71), associations between overtreatment and grey matter loss were observed in several brain regions. Specifically, significant reductions in grey matter were found in the caudate (adj ß coeff: -0.217, 95%CI: [-0.416 to -0.018], p = .033), the precentral gyri (adj ßcoeff:-0.277, 95%CI: [-0.482 to -0.073], p = .009), the superior frontal gyri (adj ßcoeff: -0.244, 95%CI: [-0.458 to -0.030], p = .026), the calcarine cortex (adj ßcoeff:-0.193, 95%CI: [-0.386 to -0.001], p = .049), the superior occipital gyri (adj ßcoeff: -0.291, 95%CI: [-0.521 to -0.061], p = .014) and the inferior occipital gyri (adj ßcoeff: -0.236, 95%CI: [-0.456 to - 0.015], p = .036). CONCLUSION: A significant proportion of older patients with diabetes and neurocognitive disorder were subjected to excessively intensive treatment. The association identified with volume loss in several specific brain regions highlights the need to further investigate the potential cerebral damages associated with overtreatment and related hypoglycemia in larger sample.

Executive function and prospective falls: a 6-year longitudinal study in community-dwelling older adults.

BACKGROUND: Older people with impaired executive function (EF) might have an increased fall risk, but prospective studies with prolonged follow-up are scarce. This study aimed to investigate the association between a) EF at baseline; b) 6-year decline in EF performance; and fall status 6 years later. METHODS: Participants were 906 community-dwelling adults aged 65-69 years, enrolled in the Lausanne 65 + cohort. EF was measured at baseline and at 6 years using clock drawing test (CDT), verbal fluency (VF), Trail Making Test (TMT) A and B, and TMT ratio (TMT-B - TMT-A/TMT-A). EF decline was defined as clinically meaningful poorer performance at 6 years. Falls data were collected at 6 years using monthly calendars over 12 months. RESULTS: Over 12-month follow-up, 13.0% of participants reported a single benign fall, and 20.2% serious (i.e., multiple and/or injurious) falls. In multivariable analysis, participants with worse TMT-B performance (adjusted Relative Risk Ratio, adjRRRTMT-B worst quintile = 0.38, 95%CI:0.19-0.75, p = .006) and worse TMT ratio (adjRRRTMT ratio worst quintile = 0.31, 95%CI:0.15-0.64, p = .001) were less likely to report a benign fall, whereas no significant association was observed with serious falls. In a subgroup analysis among fallers, participants with worse TMT-B (OR:1.86, 95%CI = 0.98-3.53, p = .059) and worse TMT ratio (OR:1.84,95%CI = 0.98-3.43,p = .057) tended to have higher odds of serious falls. EF decline was not associated to higher odds of falls. CONCLUSIONS: Participants with worse EF were less likely to report a single benign fall at follow-up, while fallers with worse EF tended to report multiple and/or injurious falls more frequently. Future studies should investigate the role of slight EF impairment in provoking serious falls in active young-old adults.

Mortality in COVID-19 older patients hospitalized in a geriatric ward: Is obesity protective?

BACKGROUNDS: To investigate the relationship between obesity and 30-day mortality in a cohort of older hospitalized COVID-19 inpatients. METHODS: Included patients were aged 70 years or more; hospitalized in acute geriatric wards between March and December 2020; with a positive PCR for COVID-19; not candidate to intensive care unit admission. Clinical data were collected from patients electronic medical records. Data on 30-day mortality were retrieved from the hospital administrative database. RESULTS: Patients included (N = 294) were on average 83.4 ± 6.7 years old, 50.7% were women, and 21.7% were obese (BMI > 30 kg/m2). At 30-day, 85 (28.9%) patients were deceased. Compared to survivors in bivariable analysis, deceased patients were older (84.6 ± 7.6 vs 83.0 ± 6.3 years), more frequently with very complex health status (63.5% vs 39.7%, P < .001), but less frequently obese (13.4% vs 24.9%, P = .033) at admission. Over their stay, deceased patients more frequently (all P < .001) developed radiologic signs of COVID-19 (84.7% vs 58.9%), anorexia (84.7% vs 59.8%), hypernatremia (40.0% vs 10.5%), delirium (74.1% vs 30.1%), and need for oxygen (87.1% vs 46.4%) compared to survivors. In multivariable analysis that controlled for all markers of poor prognosis identified in bivariable analysis, obese patients remain with 64% (adjOR 0.36, 95%CI 0.14-0.95, P = .038) lower odds to be deceased at 30-day than non-obese patients. CONCLUSIONS: In this population of older COVID-19 inpatients, an inverse association between obesity and 30-day mortality was observed even after adjusting for all already-known markers of poor prognosis. This result challenges previous observations in younger cohorts and would need to be replicated.

Older patients referred for geriatric consultation in the emergency department: characteristics and healthcare utilization.

BACKGROUND: Comprehensive geriatric assessment (CGA) is difficult to perform in the emergency department (ED) environment and performance of screening tools in identifying vulnerable older ED patients who are best candidates for a geriatric consultation remain questionable. AIM: To determine the characteristics of older patients referred for a geriatric consultation by ED staff and to investigate these patients' subsequent healthcare utilization. METHODS: Secondary analysis of data previously collected for a prospective observational study of patients aged 75 + years visiting the ED of an academic hospital in Switzerland over four months (Michalski-Monnerat et al., J Am Geriatr Soc 68(12):2914-20, 2020). Socio-demographic, health, functional (basic activities of daily living; BADL), cognitive, and affective status data were collected at admission by a research nurse using a standardized brief geriatric assessment. Information on geriatric consultations, hospitalization, discharge destination, and 30-day readmission were retrieved from hospital database. Bivariable and multivariable analyses were performed using this data set collected previously. RESULTS: Thirty-two (15.8%) of the 202 enrolled patients were referred for a geriatric consultation. Compared to the others, they were older (84.9 ± 5.4 vs 82.9 ± 5.4 years, p = .03), more impaired in BADL (4.8 ± 1.6 vs 5.5 ± 1.0, p = .01), with more comorbid conditions (5.3 ± 1.5 vs 4.5 ± 1.9, p = .03), more frequently admitted after a fall (43.7% vs 19.4%, p = .01), and hospitalized over the previous 6-month period (53.1% vs 30.6%, p = .02). Multivariable analyses that adjusted for variables significantly associated with outcomes in bivariable analysis found that being admitted after a fall (AdjOR 4.0, 95%CI 1.7-9.4, p < .01) and previously hospitalized (AdjOR 2.7, 95% CI 1.2-6.2, p = .02) remained associated with increased odds of consultation, whereas the inverse association with BADL performance remained (AdjOR 0.7, 95%CI 0.5-0.9, p = .01). Patients referred for geriatric consultation had higher odds of hospitalization (84.4% vs 49.4%; AdjOR 5.9, 95%CI 2.1-16.8, p < .01), but similar odds of home discharge when admitted, and of 30-day readmission. CONCLUSION: About one in six older ED patients were referred for a geriatric consultation who appeared to be those most vulnerable, as suggested by their increased hospitalization rate. Alternative strategies are needed to enhance access to geriatric consultation in the ED.

Instrumented 5-Time Sit-To-Stand Test: Parameters Predicting Serious Falls beyond the Duration of the Test.

BACKGROUND: Falls are a major cause of injuries in older adults. To evaluate the risk of falls in older adults, clinical assessments such as the 5-time sit-to-stand (5xSTS) test can be performed. The development of inertial measurement units (IMUs) has provided the possibility of a more in-depth analysis of the movements' biomechanical characteristics during this test. The goal of the present study was to investigate whether an instrumented 5xSTS test provides additional information to predict multiple or serious falls compared to the conventional stopwatch-based method. METHODS: Data from 458 community-dwelling older adults were analyzed. The participants were equipped with an IMU on the trunk to extract temporal, kinematic, kinetic, and smoothness movement parameters in addition to the total duration of the test by the stopwatch. RESULTS: The total duration of the test obtained by the IMU and the stopwatch was in excellent agreement (Pearson's correlation coefficient: 0.99), while the total duration obtained by the IMU was systematically 0.52 s longer than the stopwatch. In multivariable analyses that adjusted for potential confounders, fallers had slower vertical velocity, reduced vertical acceleration, lower vertical power, and lower vertical jerk than nonfallers. In contrast, the total duration of the test measured by either the IMU or the stopwatch did not differ between the 2 groups. CONCLUSIONS: An instrumented 5xSTS test provides additional information that better discriminates among older adults those at risk of multiple or serious falls than the conventional stopwatch-based assessment.

Fighting social isolation in times of pandemic COVID-19: the role of video calls for older hospitalized patients.

BACKGROUND: Loneliness and social isolation are associated with anxiety and psychological discomfort, especially amongst the oldest and fragile persons. AIMS: SILVER evaluates the acceptance of video calls by old hospitalized patients and their relatives during the ban on visits due to the COVID-19. Moreover, SILVER evaluates if the use of different communication technology is associated with different outcomes in terms of anxiety, fear of self and of others' death and mood. METHODS: SILVER is an observational multicentre study. Patients hospitalized in two geriatric units in Switzerland and in one orthogeriatric unit in Italy and their relatives were enrolled. Participants can freely choose to use phone or video calls and were evaluated over a week. We measured anxiety, fear of death and mood at baseline and at the end of the study with standard scales. The use of video or phone calls was associated to a change in these parameters by two-way ANOVA for repeated measures. RESULTS: Sixty-four patients and relatives were enrolled, 26.5% used phone calls and 73.5% video calls. The use of video calls was associated with a reduction in anxiety and fear of death in patients and relatives as compared to participants using phone calls. DISCUSSION: Old patients and their relatives accepted and appreciated the use of video calls during hospitalization; moreover, participant using video calls appears to be less anxious and less afraid of death. CONCLUSIONS: Video calls may be a useful communication tool for hospitalized older patients to keep social relationships with relatives and reduce their anxiety and fear of death. TRIAL REGISTRATION: Retrospectively registered on 1st September 2021 in ClinicalTrials.gov (NCT05000099).

[Subacute cerebellar ataxia, an uncommon SARS-CoV-2 complication infection in older adults]. / Ataxie cérébelleuse subaiguë : une atteinte atypique par le SARS-CoV-2 chez la personne âgée.

Cerebellar ataxia can be caused by neoplasia, toxics (drugs, heavy metals, alcohol), infection, vascular lesions or auto-immune and paraneoplastic pathologies. Neuroimaging must be performed urgently in case of sudden onset and serologies as well as a lumbar puncture should be performed. Several case reports of ataxia associated with COVID-19 have been published, however the underlying pathogenic mechanisms remain unclear. This is a diagnosis of exclusion when other causes are ruled out and when the ataxia appears simultaneously to COVID-19 infection. We lack data on best management, but the prognosis appears mostly favorable with good functional recovery without any specific treatment. This paper describes the case of a patient who developed a cerebellar ataxia as the only neurological manifestation of a SARS-CoV-2 infection.

Une ataxie cérébelleuse peut être causée par un processus (para)néoplasique, auto-imun, une exposition toxique, une infection ou une lésion vasculaire. Une imagerie doit être réalisée en urgence devant toute atteinte aiguë et le bilan devrait être complété par des sérologies larges et une ponction lombaire. Plusieurs cas d'ataxie liée au Covid-19 ont été décrits, dont le mécanisme étiopathogénique reste incomplètement élucidé, le diagnostic se faisant plutôt par exclusion lorsque les symptômes apparaissent de manière concomitante à l'infection. Des données manquent sur la prise en charge mais le pronostic semble favorable, avec une bonne récupération fonctionnelle. Cet article décrit le cas d'une patiente ayant présenté une ataxie cérébelleuse comme symptôme neurologique isolé contemporain d'une infection à SARS-CoV-2.

[Fast-evolving cognitive impairment: a home-based diagnosis]. / Troubles neurocognitifs d'évolution rapide.

Syphilis is a sexually transmitted disease which incidence increased over the last 10 years in Switzerland. The clinical and neurocognitive manifestations observed in case of symptomatic neurosyphilis can be very heterogeneous and can mimic neurocognitive disorders of other origins. This article discusses the diagnostic and management pitfalls in an older patient whose diagnosis of neurosyphilis was initially suspected during a home visit.

La syphilis est une maladie à transmission sexuelle dont l'incidence est en constante augmentation ces 10 dernières années en Suisse. Les manifestations cliniques et neurocognitives observées en cas de neurosyphilis symptomatique sont très hétérogènes et peu spécifiques, pouvant mimer des troubles neurocognitifs d'autre origine. Cet article discute des écueils diagnostiques et de prise en charge d'un patient âgé chez lequel un diagnostic de neurosyphilis a été évoqué lors d'une visite à domicile.

[Treatment of congestive heart failure in older persons and SGLT2 inhibitors - Having your patient's best interests at heart]. / Traitement de l'insuffisance cardiaque chez la personne âgée et inhibiteurs du SGLT2 - En avoir le cœur net.

The treatment and management of heart failure (HF) are constantly evolving. The latest guidelines recommend the use of SGLT2 inhibitors (SGLT2i) as an integral part to treating HF with reduced ejection fraction (< 40%). However, given that the patients included in these trials do not reflect the heterogeneity of the health of many elderly patients, we recommend basing the therapeutic decision on the patient's state of frailty. If a SGLT2i treatment at a standard dose (10 mg 1x/day) is recommended for robust patients, we suggest initiating treatment at 5 mg 1x/day for vulnerable patients, and then after 1 month increasing the dose to 10 mg 1x/day. Finally, for dependent patients, we recommend therapeutic abstention in the absence of sufficient scientific evidence.

La prise en charge de l'insuffisance cardiaque (IC) est en constante évolution. Les dernières recommandations préconisent l'utilisation des inhibiteurs du SGLT2 (iSGLT2) pour le traitement de l'IC à fraction d'éjection réduite (< 40%). Cependant, les populations des études ne reflètent pas l'hétérogénéité de la population âgée en termes de santé et nous proposons de baser la décision thérapeutique selon la Clinical Frailty Scale : si, pour les patients robustes, un traitement par iSGLT2 à dose standard (10 mg 1 x/jour) est préconisé, nous proposons, pour les patients vulnérables, d'initier le traitement à 5 mg 1 x/jour, puis d'augmenter à 10 mg 1 x/jour après 1 mois. Finalement, pour les patients dépendants, nous recommandons une abstention thérapeutique en l'absence d'évidences scientifiques suffisantes.

[Geriatrics]. / Gériatrie.

Sleeping enough is associated with a reduced risk of mortality and dementia. New evidence support regular physical exercise, including at home, as a corner stone intervention to prevent falls and fractures. In contrast, supplementation with high doses of vitamin D is ineffective and even deleterious in this indication and a routine screening in asymptomatic adults is not recommended. Several studies illustrate our difficulties in prescribing and deprescribing in frail older patients and a study suggests that statins in cardiovascular primary prevention should considered only when a patient's life expectancy exceeds 2.5 years. Finally, several studies have fueled the debate about screening for hearing impairment.

Dormir ni trop ni trop peu est associé à une réduction du risque de mortalité et de déclin cognitif. De nouvelles études confirment que l'exercice physique régulier, y compris à domicile, constitue la clé de voûte de la prévention des chutes et des fractures. Par contre, la supplémentation par de hautes doses de vitamine D n'est pas efficace, voire délétère, dans cette indication et le dépistage systématique d'un déficit n'est pas recommandé chez les patients adultes asymptomatiques. Plusieurs études illustrent nos difficultés à prescrire et déprescrire, chez les patients âgés fragiles, et une étude suggère qu'un traitement de statines en prévention cardiovasculaire primaire ne se justifie que si l'espérance de vie du patient dépasse 2,5 ans. Finalement, plusieurs études sont venues nourrir le débat sur le dépistage de la presbyacousie.

Falls Efficacy Is Associated With Better Gait and Functional Outcomes After Rehabilitation in Older Patients.

OBJECTIVE: To examine the relationship between falls efficacy and the change in gait speed and functional status in older patients undergoing postacute rehabilitation. DESIGN: Prospective cohort study. SETTING: Postacute rehabilitation facility. PARTICIPANTS: Patients (N=180) aged 65 years and older (mean age ± SD, 81.3±7.1y). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Data on demographics; functional, cognitive, and affective status; and falls efficacy using a 10-item version of the Falls Efficacy Scale (FES; range, 0-100) were collected upon admission. Data about gait speed and functional status (Barthel Index and Basic Activities of Daily Living [BADL]) were measured at admission and discharge. In addition, BADL performance was self-reported 1 month after discharge. RESULTS: Compared with admission, all rehabilitation outcomes improved at discharge: gait speed (0.41±0.15 m/s vs 0.50±0.16 m/s; P<.001), Barthel Index score (68.4±16.3 vs 82.5±13.6; P<.001), and BADL (3.5±1.6 vs 4.7±1.3; P<.001). Adjusting for baseline status and other potential confounders, baseline FES independently predicted gait speed (adjusted coefficient: 0.002; 95% confidence interval [CI], 0.000-0.004; P=.025) and Barthel index (adjusted coefficient: 0.225; 95% CI, 0.014-0.435; P=.037) at discharge, with higher confidence at baseline predicting greater improvement. Baseline FES was also independently associated with self-reported BADL performance at the 1-month follow-up (adjusted coefficient: 0.020; 95% CI, 0.010-0.031; P<.001). CONCLUSIONS: In older patients, higher falls efficacy predicted better gait and functional rehabilitation outcomes, independently of baseline performance. These results suggest that interventions aiming at falls efficacy improvement during rehabilitation might also contribute to enhancing gait speed and functional status in patients admitted to this setting.

Delirium in older patients undergoing aortic valve replacement: incidence, predictors, and cognitive prognosis.

BACKGROUND: Transcatheter aortic valve replacement is increasingly performed in frail older patients who were previously ineligible for a standard surgical procedure. The objectives of this study are to determine delirium incidence, predictors, and relationship with cognitive performance at 3-month follow-up in older patients undergoing aortic valve replacement (AVR). METHODS: Patients (N = 93) aged 70 years and older, undergoing transcatheter (TAVR, N = 66) or surgical (SAVR, N = 27) aortic valve replacement in an academic medical center were enrolled in this prospective cohort study. Delirium was assessed using the Confusion Assessment Method (CAM) on postoperative days 1, 2, 3, and 7. Data on patients' socio-demographics, functional status (including instrumental activities of daily living (IADL), and surgical risk scores (including Society of Thoracic Surgeons (STS) risk score), were collected at baseline. Cognitive status was assessed with the Mini-Mental Status Exam (MMSE) and the Clock Drawing Test (CDT) at baseline and 3 months after AVR. RESULTS: Delirium occurred in 21 (23%) patients, within the first three postoperative days in 95% (20/21) of the cases. Delirium incidence was lower in TAVR (13/66 = 20%) than SAVR (8/27 = 30%) patients, but this difference was not statistically significant (p = .298). Patients with delirium had lower baseline cognitive performance (median MMSE score 27.0 ± 3.0 vs 28.0 ± 3.0, p = .029), lower performance in IADL (7.0 vs 8.0, p = .038), and higher STS risk scores (4.7 ± 2.7 vs 2.9 ± 2.3, p = .020). In multivariate analyses, patients with intermediate (score > 3 to ≤8) and high (score > 8) STS risk scores had 4.3 (95%CI 1.2-15.1, p = .025) and 16.5 (95%CI 2.0-138.2, p = .010), respectively, higher odds of incident delirium compared to patients with low (score ≤ 3) STS risk scores. At 3-month follow-up (N = 77), patients with delirium still had lower MMSE score (27.0 ± 8.0 vs 28.0 ± 2.0, p = .007) but this difference did not remain significant once adjusting for baseline MMSE (ß-coefficient 1.11, 95%CI [- 3.03-0.80], p = .248). CONCLUSIONS: Delirium occurred in about one in five older patients undergoing AVR, almost essentially within the first three postoperative days. Beside cognitive performance, STS risk score could enhance the identification of high-risk older patients to better target preventative interventions.

Older People's Health-Related Behaviors: Evidence from Three Cohorts of the Lc65+ Study.

Baby-boomers might be more health-conscious than earlier birth cohorts, but limited evidence has been produced so far. To investigate such changes, this study compared health-related behaviors at age 65 to 70 among three successive five-year birth cohorts (pre-war: born 1934-1938; war: born 1939-1943 and baby-boom: born 1944-1948) representative of the community-dwelling population. Information about alcohol use, smoking, physical activity, and nutrition was compared across the three cohorts (n = 4,270 participants) using Chi-squared test. Alcohol and the mean nutritional intake score did not vary across cohorts, whereas the consumption of nonalcoholic drinks increased significantly from pre-war to war and to baby-boom cohort (p<.001). Other differences across cohorts were observed only in women: the proportion of women who never or rarely engaged in sports decreased from 52.9% in the pre-war cohort to around 43% in subsequent cohorts (p<.001), while the proportion of women who had never smoked was higher in the pre-war cohort (56.1%) than in the war and the baby-boom cohorts (49.8% and 46.8%, respectively, p<.001). Overall, these results show some positive changes in older persons' health behaviors over time. Nevertheless, considerable room remains for improving lifestyles through public health interventions.

[What's all that confusion about ? Delirium in the elderly]. / C'est quoi ce délire ? - État confusionnel aigu chez la personne âgée.

Delirium is common in community-dwelling as well as in hospitalized older persons aged 75 years and older. Often underdiagnosed, delirium is associated with increased morbidity and mortality. Screening (with CAM and 3D-CAM) and identification of older people at increased risk for delirium is essential to enhance non-pharmacological preventative measures and monitor their evolution to allowing an early diagnosis. Screening instruments are currently available, such as the CAM and 3D-CAM. Pharmacological treatment is proposed only in situations where the patients endanger him-herself or other persons. In patients without previously known cognitive impairment, a cognitive assessment is mandated within the next 6 to 12 months period following the delirium episode.

L'état confusionnel aigu (ECA) est fréquent chez le patient âgé de plus de 75 ans, tant à domicile qu'en soins aigus. Souvent sous-diagnostiqué, il s'accompagne d'une morbi-mortalité accrue. L'identification des patients à risque d'ECA, tout comme un dépistage rapide avec des échelles validées (par exemple, Confusion Assessment Method (CAM) ou 3D-CAM), sont primordiaux afin de mettre en place une prévention active essentiellement non pharmacologique. Le traitement pharmacologique devrait être réservé aux situations dans lesquelles le patient se met en danger ou met en danger d'autres personnes. Un ECA n'est pas anodin et nécessite d'être signalé pour les prises en charge ultérieures. En l'absence de troubles neurocognitifs antérieurs connus, un bilan cognitif est recommandé dans les 6 à 12 mois suivant l'ECA.

[To D or not to D ? Why and how to treat vitamin D deficiency in older patients]. / « To D or not to D ¼ : pourquoi et comment traiter l'hypovitaminose D chez les personnes âgées.

Vitamin D deficiency is so frequent in older patients (aged 65 years and older) that the international consensus does not recommend routine vitamin D measurement. Assessment of overall health status is a cornerstone before considering vitamin D supplementation, as the effect of vitamin D supplementation has only been demonstrated in vulnerable or dependent but not for robust older patients. The effect of the different modalities of oral vitamin D supplementation are equivalent : 800-1'200 IU/day, 10'000 IU/week or 30'000-50'000 IU/month. Monitoring of vitamin D blood level monitoring is not necessary because of a large therapeutic margin. In the presence of osteoporosis, a dietary or supplementation intake of 1'200 mg per day of calcium should be added.

L'hypovitaminose D est très fréquente chez les personnes âgées (65 ans et plus), à tel point que le consensus international est de ne pas doser la vitamine D en routine. L'évaluation de l'état de santé global est primordiale avant d'envisager une supplémentation en vitamine D, son effet ayant été démontré seulement chez les personnes âgées vulnérables ou dépendantes, mais pas chez les robustes. L'efficacité des modalités de supplémentation en vitamine D per os sont équivalentes : 800-1200 UI/jour, 10 000 UI/semaine ou 30 000-50 000 UI/mois. Un monitoring du taux sanguin de vitamine D n'est pas nécessaire en raison d'une large marge thérapeutique. En présence d'une ostéoporose, cette supplémentation devrait être complétée par un apport alimentaire ou une supplémentation de 1200 mg de calcium par jour.

Several studies published in 2020 showed new data supporting the prescription of statins in some old and very old patients. Despite the enthusiasm about SGLT-2 inhibitors, caution must remain in frail and dependent older diabetic patients who are not well represented in most studies. Antihypertensive treatment appears more beneficial when taken at night rather than in the morning but beware of the prescribing cascade of a diuretic when a new prescription of a calcium channel blocker. Biomarkers, including plasmatic biomarkers, are becoming increasingly important in the diagnostic strategy of neurocognitive disorders. Finally, fall prevention studies showed heterogeneous results but multimodal interventions remain mainstream.

Plusieurs études publiées en 2020 ont relancé le débat concernant la prescription de statines chez certaines personnes âgées et très âgées. Malgré l'enthousiasme concernant les inhibiteurs du SGLT2, la prudence reste de mise chez les patients diabétiques âgés vulnérables et, surtout dépendants, peu ou pas représentés dans les études. La prise nocturne d'un traitement antihypertenseur semble plus efficace que diurne, mais attention à la prescription en cascade d'un diurétique de l'anse lorsqu'un traitement anticalcique est initié. La place des biomarqueurs, y compris plasmatiques, dans la stratégie diagnostique se renforce. Si les études de prévention des chutes ont montré des résultats variables, l'approche interventionnelle multimodale reste la référence.

Validity of the older people quality of life-7 domains (OQoL-7) scale.

BACKGROUND: The Older people Quality of Life-7 domains (OQoL-7) is a 28-item multidimensional questionnaire developed to measure community-dwelling older people's QoL. The OQoL-7 assesses both importance of and satisfaction in seven QoL domains (Material resources; Close entourage; Social and cultural life; Esteem and recognition; Health and mobility; Feeling of safety; and Autonomy). This study aimed to investigate concurrent and construct validity of the OQoL-7. A secondary aim was to compare different methods of weighting participants' ratings of satisfaction according to their individual ratings of importance, as compared to the OQoL-7 total score (unweighted). METHODS: Data came from the first and second samples of the Lausanne cohort 65+ study, assessed at the same age of 72-77 years in 2011 (N = 1117) and 2016 (N = 1091), respectively. To assess concurrent validity, the OQoL-7 was compared to other measures of the same concept (single QoL item) or related concepts (self-rated health, SF-12). Construct validity was tested by comparing subscores in the seven QoL domains in the presence and absence of two stressful events during the preceding year (financial difficulties and relationship difficulties). The effect of importance weighting was assessed using moderated regression analysis. RESULTS: The OQoL-7 total score was significantly associated with the single QoL item (Spearman's rho 0.46), self-rated health (Spearman's rho 0.34), SF-12 physical (Spearman's rho 0.22) and mental (Spearman's rho 0.28) component scores. Large differences (Cohen's d > 0.8) were observed in the presence or absence of stressful events in the expected QoL domains: "Material resources" in the presence or absence of "Financial difficulties" (Cohen's d 1.34), and "Close entourage" in the presence or absence of "Relationship difficulties" (Cohen's d 0.84). Importance weighting resulted in a very small improvement in the prediction of the single QoL item (ΔR2 0.018). All results were highly consistent across 2011 and 2016 samples. CONCLUSIONS: The OQoL-7 showed adequate concurrent and construct validity in two samples of older people. In future studies, the decision to use weighted or unweighted scores will depend on the priority given to either optimizing the prediction of QoL or limiting the burden on respondents and the amount of missing data.

Unknown osteoporosis in older patients admitted to post-acute rehabilitation.

BACKGROUND: Osteoporotic fractures are associated with increased morbidity, mortality, and increased health care use. As the number of older adults increases, identifying those at increased risk for osteoporotic fractures has become of utmost importance to providing them with preventive and therapeutic interventions. AIMS: To determine the prevalence of unknown clinical and densitometric osteoporosis and to investigate the performance of different diagnostic strategies for osteoporosis in elderly patients admitted to rehabilitation. METHOD: This is an observational study. Eligible participants were older adults admitted to rehabilitation in an academic hospital in Switzerland over an 11-month period. Patients with previously unknown osteoporosis underwent dual-energy X-ray absorptiometry (DXA), vertebral fracture assessment (VFA), and history review for past fractures. RESULTS: Complete assessment was available for 252 patients. Previously undiagnosed osteoporosis was identified in 62.3% of these patients, a proportion that was higher among women (71.5%) than men (44.8%). DXA proved most sensitive, followed by VFA and history review. Results differed across gender: DXA remained the most sensitive single test among women, but VFA proved most sensitive in men. The best test to combine with history review was DXA in women (detection increasing from 47.5 to 93.2%) and VFA in men (detection increasing from 35.9 to 84.6%). CONCLUSIONS: Prevalence of previously unknown osteoporosis appears very high in elderly patients admitted to post-acute rehabilitation. The combination of history review of previous fractures with DXA in women and with VFA in men appears the best two-step strategy to improving detection of osteoporosis in this population.
