"TiC-TUG": technology in clinical practice using the instrumented timed up and go test-a scoping review

Digitized assessments have a considerable potential to guide clinicial decision making and monitor progress and disease trajectories. The Timed Up and Go test (TUG) has been long established for assessment in geriatric medicine and instrumented versions (iTUG) have been developed and validated. This scoping review includes studies that applied the iTUG and aims to identify use cases to show where and how iTUG assessment could guide interventions and clinical management. The literature search was limited to peer-reviewed studies that performed pre- and post-intervention measurements with a 3-meter TUG instrumented with body-worn technology in samples of at least 20 subjects aged 60+ years. Of 3018 identified articles 20 were included. Four clinical use cases were identified: stratification for subsequent therapy, monitoring of disease or treatment-associated changes and evaluation of interventions in patients with idiopathic normal pressure hydrocephalus (1), and patients with Parkinson's disease (2); monitoring after joint replacement surgery (3), and evaluation after different exercise and rehabilitation interventions (4). The included studies show diversity in terms of iTUG technology and procedures. The identified use cases highlight clinical relevance and high potential for the clinical application of the iTUG. A consensual approach as well as comprehensive reporting would help to further exploit the potential of the iTUG to support clinical management. Future studies should investigate the benefits of segmental iTUG analysis, responsiveness and participants' perspectives on clinically meaningful changes in iTUG.

[Legally improved access to geriatric rehabilitation - prerequisites and weaknesses]

Geriatric rehabilitation is a cornerstone of the German healthcare system to maintain the functional capacity of older patients and prevent the need for long-term care. Until recently, access to geriatric rehabilitation was largely limited to post-acute care. With the introduction of new legislation, patients aged 70 and over can be referred to geriatric rehabilitation by practitioners. However, in order to prescribe geriatric rehabilitation, physicians must document relevant diagnoses supported by the results of a series of functional or cognitive assessments. Alongside this information, the SINGER profile has been introduced. It is mandatory, although there is currently no manual to guide assessment with this tool. Diagnoses and test results must be consistent in documenting the need for geriatric rehabilitation. However, individual assessment of resources and motivation are prerequisites that need to be assessed by prescribing practitioners prior to prescription, considering the structure of the available formats. First analyses document improvement in access to geriatric rehabilitation but point to limited availability.

Predictors of 2-Year Post-Discharge Mortality in Hospitalized Older Patients

BACKGROUND

Understanding prognostic factors for adverse health outcomes is clinically relevant for improving treatment decision-making processes, potentially leading to enhanced patient prognosis. This secondary analysis of a prospective observational study aimed to identify independent factors associated with 2-year post-discharge mortality in acutely hospitalized older patients.

METHODS

All-cause mortality and date of death of 115 patients (83.3 ± 6.3 years, females: n = 75, 65.2%) admitted to acute geriatric wards were determined two years after hospital discharge through telephone interviews. Potential prognostic factors measured at hospital admission included demographic and clinical characteristics, nutritional, cognitive, and psychological status, Fried frailty phenotype, functioning in activities of daily living, locomotor capacity, and 24 h in-hospital mobility and objectively measured physical activity (PA) behaviors.

RESULTS

The 2-year mortality rate was 36.7% (n = 41). Univariate and multivariate Cox proportional hazards regression models revealed that mean daily PA level (hazards ratio (HR) = 0.59, 95% confidence interval (CI) 0.90-1.00; p = 0.042), frailty (HR = 3.39, 95% CI 1.20-9.51; p = 0.020), and underweight, in contrast to overweight (HR = 3.10, 95% CI 1.07-9.01; p = 0.038), at hospital admission were independently predictive of post-discharge mortality.

CONCLUSION

PA, frailty, and underweight at hospital admission should be considered when evaluating long-term survival prognosis, establishing risk profiles, and developing personalized care pathways in acute hospital care of older adults.

Mobility outcomes and associated factors of acute geriatric care in hospitalized older patients: results from the PAGER study

PURPOSE

To examine distinct mobility outcomes (locomotor capacity, physical activity, life-space mobility) of acute geriatric care (AGC) in acutely hospitalized older adults and identify predictors associated with these outcomes.

METHODS

The PAGER study was designed as a prospective observational study. Mobility outcomes of 107 hospitalized older patients (age = 83.2 ± 6.4 years, female: n = 68, 63.6%) receiving AGC were measured at hospital admission and discharge. Locomotor capacity was assessed with the Short Physical Performance Battery (SPPB), 24-h physical activity (step count) with an activity monitor, and life-space mobility with the Life-Space Assessment in Institutionalized Settings (LSA-IS). Baseline demographical, clinical, physical, cognitive, and psychological characteristics were analyzed as candidate predictors of mobility outcomes.

RESULTS

SPPB (median [interquartile range] 4.0 [2.8-5.0] pt. vs. 5.0 [3.0-6.3] pt.), step count (516 [89-1806] steps vs. 1111 [228-3291] steps), and LSA-IS total score (10.5 [6.0-15.0] pt. vs. 16.3 [12.0-24.1] pt.) significantly improved during AGC (all p < 0.001). Adjusting for baseline status, frailty was identified as an independent negative predictor of SPPB, step count, and LSA-IS at discharge (p = 0.003-0.005). Barthel Index was also independently positively associated with step count (p = 0.017) at discharge, as was the mean daily PA level with SPPB (p = 0.027) at discharge, both independent of baseline status.

CONCLUSION

AGC improves distinct mobility outcomes in hospitalized older patients. Frailty was consistently found to be an independent negative predictor of all mobility outcomes. Frailty assessment in AGC may be important to identify patients at risk for decreased treatment gains in mobility. Early PA promotion in AGC seems to be beneficial in improving patients' locomotor capacity.

Multimodal home-based rehabilitation intervention after discharge from inpatient geriatric rehabilitation (GeRas): study protocol for a multicenter randomized controlled trial

BACKGROUND

Geriatric rehabilitation aims to maintain the functional reserves of older adults in order to optimize social participation and prevent disability. After discharge from inpatient geriatric rehabilitation, patients are at high risk for decreased physical capacity, increased vulnerability, and limitations in mobility. As a result, ageing in place becomes uncertain for a plethora of patients after discharge from geriatric rehabilitation and effective strategies to prevent physical decline are required. Collaboration between different health-care providers is essential to improve continuity of care after discharge from inpatient geriatric rehabilitation. The aim of this study is to evaluate the effectiveness of a multi-professional home-based intervention program (GeRas) to improve functional capacity and social participation in older persons after discharge from inpatient geriatric rehabilitation.

METHODS

The study is a multicenter, three-arm, randomized controlled trial with a three-month intervention period. Two hundred and seventy community-dwelling older people receiving inpatient geriatric rehabilitation will be randomized with a 1:1:1 ratio to one of the parallel intervention groups (conventional IG or tablet IG) or the control group (CG). The participants of both IGs will receive a home-based physical exercise program supervised by physical therapists, a nutritional recommendation by a physician, and social counseling by social workers of the health insurance company. The collaboration between the health-care providers and management of participants will be realized within a cloud environment based on a telemedicine platform and supported by multi-professional case conferences. The CG will receive usual care, two short handouts on general health-related topics, and facultative lifestyle counseling with general recommendations for a healthy diet and active ageing. The primary outcomes will be the physical capacity measured by the Short Physical Performance Battery and social participation assessed by the modified Reintegration to Normal Living Index, three months after discharge.

DISCUSSION

The GeRas program is designed to improve the collaboration between health-care providers in the transition from inpatient geriatric rehabilitation to outpatient settings. Compared to usual care, it is expected to improve physical capacity and participation in geriatric patients after discharge from inpatient geriatric rehabilitation.

Validity, Reliability, Responsiveness, and Feasibility of the Life-Space Assessment Administered via Telephone in Community-Dwelling Older Adults

BACKGROUND AND OBJECTIVES

The life-space assessment (LSA) is the most commonly used questionnaire to assess life-space mobility (LSM) in older adults, with well-established psychometric properties for face-to-face (FF) administration. However, these properties have not yet been explicitly studied when the LSA is administered by telephone. The aim of this study was to evaluate the concurrent and construct validity, test-retest reliability, responsiveness, and feasibility of a telephone-based LSA version (TE-LSA) in older adults.

RESEARCH DESIGN AND METHODS

Fifty community-dwelling older adults (age = 79.3 ± 5.3 years) participated in the study. Concurrent validity was assessed against the FF-LSA construct validity by testing 15 a priori hypotheses on expected associations with LSM determinants, test-retest reliability via 2 telephone surveys 1 week apart, responsiveness after 8.5 ± 1.8 months in participants with improved, stable, and worsened mobility defined by 2 external criteria, and feasibility by the completion rate/time and ceiling/floor effects.

RESULTS

Good to excellent agreement between the 2 different administration methods was found (intraclass correlation coefficient [ICC2,1] = 0.73-0.98). Twelve of 15 (80%) hypotheses on construct validity were confirmed. ICCs for test-retest reliability were good to excellent (ICC2,1 = 0.62-0.94). Minimal detectable change for the TE-LSA total score was 20 points. Standardized response means were large for worsened (0.88), moderate for improved (0.68), and trivial for stable participants (0.04). Completion rate was 100% and mean completion time was 5.5 ± 3.3 min. No ceiling or floor effects were observed for the TE-LSA total score.

DISCUSSION AND IMPLICATIONS

Telephone administration of the LSA is valid, reliable, responsive, and feasible for assessing LSM in community-dwelling older adults.

[Frailty: Concept and Diagnosis]

Frailty increases the older adult's vulnerability to suffer adverse health outcomes. To date, no gold standard for the diagnosis of frailty exists. This article provides an overview of the most relevant frailty instruments and their scope of application.

Consequences of contact restrictions for long-term care residents during the first months of COVID-19 pandemic: a scoping review

During the early stages of the COVID-19 pandemic, stringent measures were implemented in most countries to limit social contact between residents of long-term care facilities (LTCF) and visitors. The objective of this scoping review was to identify and map evidence of direct and indirect consequences of contact restrictions, guided by three conceptual perspectives: (1) stress and learned helplessness (i.e., failure to use coping behaviors even when they are available and actionalble); (2) social contact loss; and (3) 'total institution' (i.e., a facility operates following a fixed plan due to spelled-out rules and norms, controlled by institutional representatives). We used the framework for conducting a scoping review by Arksey and O'Malley; included were peer-reviewed manuscripts reporting on the outcomes of contact restrictions from the beginning of the pandemic until the end of 2020. After removing duplicates, 6,656 records were screened and 62 manuscripts included. Results pertaining to the stress and learned helplessness perspective primarily focused on depressive symptoms, showing substantial increases compared to the pre-pandemic period. Studies examining cognitive and functional decline, as well as non-COVID-19 related mortality, were limited in number and presented mixed findings. The majority of study outcomes related to the social contact loss perspective focused on loneliness, but the study designs did not adequately allow for comparisons with the pre-pandemic status. The evidence concerning outcomes related to the 'total Institution' perspective was inconclusive. Although detrimental effects of social isolation in the long-term care context found support particularly in the negative affect domain, other outcome areas did not allow for definitive conclusions due to considerable variations in findings and, in some cases, insufficient statistical power.

[Motivational Reasons and Perceptions about Future Participation of Older People in the Research and Development Process of Health Technologies: a Mixed Methods Study]

BACKGROUND

Although digital approaches for disease prevention in older people have a high potential and are being used more often, there are still inequalities in access and use. One reason could be that in technology development future users are insufficiently taken into consideration, or involved very late in the process using inappropriate methods. The aim of this work was to analyze the motivation of older people participating, and their perceptions of future participation in the research and development process of health technologies aimed at health care for older people.

METHODOLOGY

Quantitative and qualitative data from one needs assessment and two evaluation studies were analyzed. The quantitative data were analyzed descriptively and the qualitative data were analyzed content-analytically with inductive-deductive category formation.

RESULTS

The median age of the 103 participants (50 female) was 75 years (64-90), most of whom were interested in using technology and had prior experience of study participation. Nine categories for participation motivation were derived. A common motivation for participation was to promote and support their own health. Respondents were able to envision participation both at the beginning of the research process and at its end. In terms of technique development, different ideas were expressed, but there was a general interest in technological development. Methods that would enable exchange with others were favored most.

CONCLUSIONS

Differences in motivation to participate and ideas about participation were identified. The results provide important information from the perspective of older people and complement the existing state of research.

Co-Creating a Digital Life-Integrated Self-Assessment for Older Adults: User Experience Study

BACKGROUND

Older adults are at increased risk of developing health disorders and functional decline. However, owing to time constraints and considerable effort, physicians rarely conduct comprehensive assessments to detect early signs of negative trajectories. If designed properly, digital technologies could identify health risks already at a preclinical stage, thereby facilitating preventive efforts and targeted intervention. For this purpose, a Life-integrated Self-Assessment (LiSA) tablet system will be developed through a structured co-creation process.

OBJECTIVE

This study aims to investigate older adults' perceptions of different self-assessment domains, components affecting user experience, risks and benefits associated with LiSA, characteristics of potential LiSA users, and the LiSA concept in general.

METHODS

A total of 10 community-dwelling older adults aged ≥70 years were recruited. In total, 6 co-creation workshops were held and started with expert input followed by semistructured discussion rounds. Participants performed hands-on activities with a tablet, including testing of preinstalled self-assessment apps. All workshops were audio recorded and additionally documented by the researchers using flipcharts, notes, and photos. Qualitative content analysis was used to analyze the data following a deductive-inductive approach guided by the Optimized Honeycomb Model for user experience.

RESULTS

The group (mean age 77.8, SD 5.1 years) was heterogeneous in terms of previous technology experience and health status. The mean workshop duration was 2 hours (122.5, SD 4.43 min), and an average of 8 (SD 1.15) participants attended each workshop. A total of 11 thematic categories were identified, covering results on all research questions. Participants emphasized a strong interest in conducting a digital self-assessment of physical activity and function and sensory and cognitive functions and requested additional features such as recommendations for actions or reminders. LiSA was perceived as empowering and a motivator to engage in active health care planning as well as enabling shared and informed decision-making. Concerns and barriers included the lack of technical competence, feelings of frustration, and fear of being left alone, with negative assessment results. In essence, participants expressed a positive attitude toward using LiSA repeatedly and identified it as an option to increase the chances of maintaining independence when growing older.

CONCLUSIONS

The co-creation participants supported the LiSA approach and were interested in performing regular self-assessments on a long-term basis. In their opinion, LiSA should include relevant assessments capturing physical activity and function and sensory and cognitive functions as well as recommendations for actions. It should be customizable to individual needs. These results will form the basis for a prototype. Iterative development and validation will aim to make LiSA accessible in the public domain as a reliable tablet-based system for self-assessment.

Feasibility, effectiveness and acceptability of two perturbation-based treadmill training protocols to improve reactive balance in fall-prone older adults (FEATURE): protocol for a pilot randomised controlled trial

INTRODUCTION

Perturbation-based balance training (PBT) targets the mechanism of falls (eg, slipping, tripping) to specifically train the recovery actions needed to avoid a fall. This task-specific training has shown great promise as an effective and efficient intervention for fall prevention in older adults. However, knowledge about the dose-response relationship of PBT, as well as its feasibility and acceptability in older adults with increased risk of falling is still limited. Thus, the aim of this study is to compare the effectiveness of two different treadmill PBT protocols for improving reactive balance control in fall-prone older adults, and to evaluate the feasibility and acceptability of these protocols.

METHODS AND ANALYSIS

The study is designed as a pilot randomised controlled trial with a 6-week intervention and 6-week follow-up period. Thirty-six community-dwelling, fall-prone (Timed Up and Go >12 s, habitual gait speed <1.0 m/s and/or fall history) older adults will be randomised (1:1) to receive six (weeks 1-6) or two treadmill PBT sessions (weeks 1+6) plus four conventional treadmill training sessions (weeks 2-5). Training sessions are conducted 1×/week for 30 min. Each PBT will include 40 perturbations in anterior-posterior and mediolateral directions. Reactive balance after perturbations in standing (Stepping Threshold Test (STT)) and walking (Dynamic Stepping Threshold Test (DSTT)) will be assessed as the primary outcome for effectiveness. Secondary outcomes are spatiotemporal and kinematic parameters collected during STT, DSTT and PBT, maximum perturbation magnitude for each PBT session, static and dynamic balance, physical capacity, physical activity, concerns with falling and executive functions. Feasibility will be assessed via training adherence, drop-out rate, perturbations actually performed and adverse events; and acceptability via self-designed questionnaire and focus groups.

ETHICS AND DISSEMINATION

The study has been approved by the Ethics Committee of the Medical Faculty Heidelberg (S-602/2022). Findings will be disseminated through publications in peer-reviewed journals and conference presentations.

Validation of a telephone-based administration of the simplified nutritional appetite questionnaire

BACKGROUND

Anorexia of aging is characterized by an age-associated reduction of appetite, whose aetiology in most cases is multifactorial and which often triggers malnutrition. The Simplified Nutritional Appetite Questionnaire (SNAQ) is an established screening tool. This study aimed to investigate reliability, validity, and feasibility of its telephone administration (T-SNAQ) in German community-dwelling older adults.

METHODS

This cross-sectional single-centre study recruited participants from April 2021 to September 2021. First, the SNAQ was translated into German according to an established methodology. After translation, reliability, construct validity, and feasibility of the T-SNAQ were analysed. A convenience sample of community-dwelling older adults aged ≥70 years was recruited. The following measurements were applied to all participants: T-SNAQ, Mini Nutritional Assessment - Short Form (MNA-SF), six-item Katz index of independence in activities of daily living (ADL), eight-item Lawton instrumental activities of daily living (IADL), telephone Montreal Cognitive Assessment (T-MoCA); FRAIL scale, Geriatric Depression Scale (GDS-15) and Charlson co-morbidity index as well as daily caloric and protein intake.

RESULTS

One hundred twenty participants (59.2% female) with a mean age of 78.0 ± 5.8 years were included in the present study. The percentage of participants identified with poor appetite based on T-SNAQ was 20.8% (n = 25). T-SNAQ showed a good internal reliability with a Cronbach's alpha coefficient of 0.64 and a good test-retest reliability [intraclass coefficient of 0.95 (P < 0.05)]. Regarding construct validity, T-SNAQ was significantly positively correlated with MNA-SF (r = 0.213), T-MoCA (r = 0.225), daily energy (r = 0.222) and protein intake (r = 0.252) (P < 0.05). It also demonstrated a significant negative association with GDS-15 (r = -0.361), FRAIL scale (r = -0.203) and Charlson co-morbidity index (r = -0.272). Regarding applicability, the mean time for T-SNAQ was 95 s and completion rate was 100%.

CONCLUSIONS

The T-SNAQ is a feasible screening instrument for anorexia of aging in community-dwelling older adults via telephone interviews.

Nutritional Care Practices in Geriatric Rehabilitation Facilities across Europe: A Cross-Sectional Study

Many patients in geriatric rehabilitation (GR) are physically frail at the time of admission and suffer from malnutrition and sarcopenia, which may worsen rehabilitation outcomes. This study aims to obtain insight into the current nutritional care practices in GR facilities across Europe.

METHODS

In this cross-sectional study, a questionnaire focused on nutritional care practices in GR was distributed across experts in EUGMS member countries. Data were analyzed by using descriptive statistics.

RESULTS

In total, 109 respondents working in 25 European countries participated, and the results showed that not all GR patients were screened and treated for malnutrition, and not all participants used (inter)national guidelines when performing nutritional care. The results also showed variations across European geographical areas related to screening and treatment of malnutrition, sarcopenia, and frailty. Even though the participants underlined the importance of dedicating time to nutritional care, they experienced barriers in its implementation, which were mostly due to a lack of resources.

CONCLUSION

As malnutrition, sarcopenia, and frailty are often present in patients admitted to GR, in addition to being interrelated, it is recommended to develop an integrated approach to screening and treatment of all three clinical problems.

Validity and reliability of the Apple Health app on iPhone for measuring gait parameters in children, adults, and seniors

This study assessed the concurrent validity and test-retest-reliability of the Apple Health app on iPhone for measuring gait parameters in different age groups. Twenty-seven children, 28 adults and 28 seniors equipped with an iPhone completed a 6-min walk test (6MWT). Gait speed (GS), step length (SL), and double support time (DST) were extracted from the gait recordings of the Health app. Gait parameters were simultaneously collected with an inertial sensors system (APDM Mobility Lab) to assess concurrent validity. Test-retest reliability was assessed via a second iPhone-instrumented 6MWT 1 week later. Agreement of the Health App with the APDM Mobility Lab was good for GS in all age groups and for SL in adults/seniors, but poor to moderate for DST in all age groups and for SL in children. Consistency between repeated measurements was good to excellent for all gait parameters in adults/seniors, and moderate to good for GS and DST but poor for SL in children. The Health app on iPhone is reliable and valid for measuring GS and SL in adults and seniors. Careful interpretation is required when using the Health app in children and when measuring DST in general, as both have shown limited validity and/or reliability.

Frailty as a Marker for the Plasma Concentrations of Direct Oral Anticoagulants in Older Patients: Results of an Exploratory Study

BACKGROUND

Frailty makes older adults vulnerable to adverse health outcomes and can modify pharmacokinetics and drug exposure.

OBJECTIVE

We aimed to explore the relationship between different frailty assessments and trough plasma concentrations of direct oral anticoagulants in older patients.

METHODS

The frailty status of adults aged ≥ 70 years receiving regular direct oral anticoagulant medication was assessed by four different instruments: Fried physical phenotype, Rockwood frailty index, Short Physical Performance Battery, and FRAIL scale. The two performance measures "slow gait speed" and "weak grip strength" were used to build a separate score depending on the number of positive criteria (none, one, two). For each participant, a single steady-state direct oral anticoagulant trough plasma concentration was collected, dose-normalized, and its relationship to the various frailty assessments analyzed.

RESULTS

Forty-two participants completed the study, with most using apixaban (n = 22). Dose-normalized apixaban trough concentrations were 2.48-fold higher in frail participants (Fried phenotype) than in robust participants (p = 0.009) and correlated positively with Fried physical phenotype (r_s = 0.535, p = 0.010) and negatively with Short Physical Performance Battery (r_s = - 0.434, p = 0.044). Compared with participants who met none of the criteria "slow gait speed" and "weak grip strength", apixaban trough concentrations were approximately 1.9-fold higher in participants who were positive for one (p = 0.018) or two (p = 0.013) of these measures.

CONCLUSIONS

In this exploratory study, higher levels of frailty on performance-based frailty assessments were associated with higher apixaban exposure in older adults.

Effects of a Home-Based Physical Training and Activity Promotion Program in Community-Dwelling Older Persons with Cognitive Impairment after Discharge from Rehabilitation: A Randomized Controlled Trial

BACKGROUND

Older people with cognitive impairment (CI) are at high risk for mobility limitations and adverse outcomes after discharge from geriatric rehabilitation settings. The aim was to estimate the effects of a specifically designed home-based physical training and activity promotion program on physical capacity, different aspects of physical activity (PA), and psychosocial status.

METHODS

Patients with mild to moderate CI (Mini-Mental State Examination [MMSE]: 17-26 points) discharged home after rehabilitation were included in this randomized, double-blind, placebo-controlled trial with a 12-week intervention and 12-week follow-up period. The intervention group performed a CI-specific, autonomous, home-based strength, balance, and walking training supported by tailored motivational strategies to foster training adherence and promote PA. The control group participated in an unspecific motor placebo activity. Primary outcomes were physical capacity (Short Physical Performance Battery [SPPB]) and PA (sensor-based activity time).

RESULTS

Among 118 randomized participants (82.3 ± 6.0 years) with CI (MMSE: 23.3 ± 2.4) and high levels of multimorbidity, those participants undergoing home-based training demonstrated superior outcomes to the control group in SPPB (mean difference between groups 1.9 points; 95% CI: 1.0-2.8; p < .001), with persistent benefits over the follow-up (1.3 points; 95% CI: 0.4-2.2; p < .001). There were no differences in PA across any time points. Among secondary outcomes, fear of falling and activity avoidance behavior were reduced in the intervention group at all time points, life-space mobility improved short-term.

CONCLUSIONS

The results demonstrate clinically important benefits of an individually tailored autonomous physical training and activity promotion program on physical capacity and secondary outcomes in different domains in a vulnerable, multimorbid population.

Nurses’ competence in recognition and management of delirium in older patients: development and piloting of a self-assessment tool

Background

Delirium is a common condition in elderly inpatients. Health care professionals play a crucial role in recognizing delirium, initiating preventive measures and implementing a multicomponent treatment strategy. Yet, delirium often goes unrecognized in clinical routine. Nurses take an important role in preventing and managing delirium. This study assesses clinical reasoning of nurses using case vignettes to explore their competences in recognizing, preventing and managing delirium.

Methods

The study was conducted as an online survey. The questionnaire was based on five case vignettes presenting cases of acutely ill older patients with different subtypes of delirium or diseases with overlapping symptoms. In a first step, case vignettes were developed and validated through a multidisciplinary expert panel. Scoring of response options were summed up to a Geriatric Delirium Competence Questionnaire (GDCQ) score including recognition and management tasks The questionnaire was made available online. Descriptive analyses and group comparisons explores differences between nurses from different settings. Factors explaining variance in participants’ score were evaluated using correlations and linear regression models.

Results

The questionnaire demonstrated good content validity and high reliability (kappa = 0.79). The final sample consisted of 115 nurses. Five hundred seventy-five case vignettes with an accuracy of 0.71 for the correct recognition of delirium presence or absence were solved. Nurses recognized delirium best in cases describing hyperactive delirium (79%) while hypoactive delirium was recognized least (44%). Nurses from geriatric and internal medicine departments had significantly higher GDCQ-score than the other subgroups. Management tasks were correctly identified by most participants.

Conclusions

Overall, nurses’ competence regarding hypoactive delirium should be strengthened. The online questionnaire might facilitate targeting training opportunities to nurses’ competence.

Designing and applying technology for prevention-Lessons learned in AEQUIPA and its implications for future research and practice

Almost all Western societies are facing the challenge that their population structure is changing very dynamically. Already in 2019, ten countries had a population share of at least 20 percent in the age group of 64 years and older. Today's society aims to improve population health and help older people live active and independent lives by developing, establishing, and promoting safe and effective interventions. Modern technological approaches offer tremendous opportunities but pose challenges when preventing functional decline. As part of the AEQUIPA Prevention Research Network, the use of technology to promote physical activity in older people over 65 years of age was investigated in different settings and from various interdisciplinary perspectives, including technology development and evaluation for older adults. We present our findings in three main areas: (a) design processes for developing technology interventions, (b) older adults as a user group, and (c) implications for the use of technology in interventions. We find that cross-cutting issues such as time and project management, supervision of participants, ethics, and interdisciplinary collaboration are of vital importance to the success of the work. The lessons learned are discussed based on the experiences gained in the overall AEQUIPA network while building, particularly on the experiences from the AEQUIPA sub-projects TECHNOLOGY and PROMOTE. Our experiences can help researchers of all disciplines, industries, and practices design, study and implement novel technology-based interventions for older adults to avoid pitfalls and create compelling and meaningful solutions.

[Digital geriatric self-assessment-A narrative review]

BACKGROUND

Digital health apps have a large potential for autonomous screening and monitoring of older people with respect to maintaining their independence. Due to demographic change and the shortage of specialized personnel in medicine, these premedical self-assessment apps could be of great value in the future.

OBJECTIVE

This narrative review enables the assessment of whether a digital geriatric self-assessment for older people ≥ 70 years is feasible using currently available apps.

MATERIAL AND METHODS

A search was carried out for apps that enable a self-assessment in the following domains: physical capacity, cognition, emotion, nutrition, sensory perception and context factors. Based on predefined criteria apps were selected and presented.

RESULTS

Self-assessment apps could be identified in four of the six domains: physical capacity, cognition, emotion and sensory perception. In total five apps are presented as examples. No apps were identified regarding nutrition and context factors. Numerous self-assessment apps were identified for the field of physical activity.

CONCLUSION

The presented results indicate that digital self-assessment can currently be realized for certain domains of the comprehensive geriatric assessment. New promising apps are currently under development. More research is needed to verify test quality criteria and usability of available apps. Furthermore, there is a need for a platform that integrates individual assessment apps to provide users with an overview of the results and recommendations.

Dietary protein intake and health-related outcomes: a methodological protocol for the evidence evaluation and the outline of an evidence to decision framework underlying the evidence-based guideline of the German Nutrition Society

PURPOSE

The present work aimed to delineate (i) a revised protocol according to recent methodological developments in evidence generation, to (ii) describe its interpretation, the assessment of the overall certainty of evidence and to (iii) outline an Evidence to Decision framework for deriving an evidence-based guideline on quantitative and qualitative aspects of dietary protein intake.

METHODS

A methodological protocol to systematically investigate the association between dietary protein intake and several health outcomes and for deriving dietary protein intake recommendations for the primary prevention of various non-communicable diseases in the general adult population was developed.

RESULTS

The developed methodological protocol relies on umbrella reviews including systematic reviews with or without meta-analyses. Systematic literature searches in three databases will be performed for each health-related outcome. The methodological quality of all selected systematic reviews will be evaluated using a modified version of AMSTAR 2, and the outcome-specific certainty of evidence for systematic reviews with or without meta-analysis will be assessed with NutriGrade. The general outline of the Evidence to Decision framework foresees that recommendations in the derived guideline will be given based on the overall certainty of evidence as well as on additional criteria such as sustainability.

CONCLUSION

The methodological protocol permits a systematic evaluation of published systematic reviews on dietary protein intake and its association with selected health-related outcomes. An Evidence to Decision framework will be the basis for the overall conclusions and the resulting recommendations for dietary protein intake.

Drug Treatment of Hypercholesterolemia in Older Adults: Focus on Newer Agents

There is increasing research interest in cholesterol-lowering therapy in older patients. The newer lipid-lowering agents (the proprotein convertase subtilisin/kexin type 9 [PCSK9] inhibitors evolocumab and alirocumab; the PCSK9 synthesis inhibitor inclisiran, and the adenosine triphosphate–citrate lyase inhibitor bempedoic acid) might also provide more options for the future treatment of older patients. Data analyses of the phase III outcome trials of the PCSK9 inhibitors suggest that their clinical benefits are maintained at older ages and that there is no increased relative risk of adverse events in older patients; however, data from patients aged ≥ 75 years and particularly aged ≥ 85 years are limited, and the trials did not collect information on the frailty status of patients. Frailty is a predictor of adverse outcomes, including mortality, and might help guide therapy decisions. To date, no outcome data are available for cardiovascular endpoints for the low-density lipoprotein cholesterol-lowering drugs inclisiran and bempedoic acid. Except for the risk of gout and tendon rupture with bempedoic acid, which remains to be further characterized in larger populations, the safety profile of the novel lipid-lowering agents in older patients seems favorable. The newer lipid-lowering agents could be added to other lipid-lowering medication or used as an alternative treatment in older patients with documented statin intolerance (as is already recommended in guidelines for the PCSK9 inhibitors), such as myopathy. Especially in older patients needing high-intensity therapy despite polypharmacy or certain comedications, the absence of clinically relevant drug–drug interactions with the PCSK9 inhibitors and inclisiran might be an advantage.

Evaluating the task effectiveness and user satisfaction with different operation modes of an assistive bathing robot in older adults

Bathing robots have the potential to foster the independence of older adults who require assistance with bathing. Making human-robot interaction (HRI) for older persons as easy, effective, and user-satisfying as possible is, however, a major challenge in the development of such robots. The study aimed to evaluate the effectiveness (coverage, step effectiveness) and user satisfaction (After-Scenario Questionnaire, ASQ) with three operation modes (autonomous operation, shared control, tele-manipulation) for the HRI with a bathing robot in potential users. Twenty-five older adults who require bathing assistance tested these operation modes in a water rinsing task for the upper back. Autonomous operation led to maximum effectiveness (100%), which was significantly worse in the shared control (51.6-79.4%, p ≤ 0.001) and tele-manipulation mode (43.9-64.4%, p < .001). In the user-controlled modes, effectiveness decreased with decreasing robot assistance (shared control: 51.6-79.4% vs. tele-manipulation: 43.9-64.4%, p = 0.009-0.016). User satisfaction with the autonomous operation (ASQ: 2.0 ± 1.0pt.) was higher than with the tele-manipulation mode (ASQ: 3.0 ± 1.4pt., p = 0.003) and in trend also than with the shared control mode (ASQ: 2.5 ± 1.5pt., p = 0.071). Our study suggests that for an effective and highly satisfying HRI with a bathing robot in older users, operation modes with high robot autonomy requiring a minimum of user input seem to be necessary.

A multifactorial interdisciplinary intervention to prevent functional and mobility decline for more participation in (pre-)frail community-dwelling older adults (PromeTheus): study protocol for a multicenter randomized controlled trial

Background

Age-related decline in physical capacity can lead to frailty, associated with an increased vulnerability to adverse health outcomes and greater healthcare utilization. In an aging population, effective strategies to prevent physical decline and frailty, and preserve independence are needed. Prevention programs for vulnerable community-dwelling older adults are, however, often not yet established and implemented in routine practice. Research on the feasibility, implementation, and (cost-)effectiveness of multifactorial, interdisciplinary intervention programs that take advantage of available services of healthcare providers is also limited. The main aim of this study is to evaluate the effectiveness of such an intervention program (PromeTheus) to prevent functional and mobility decline for more participation in community-dwelling (pre-)frail older adults.

Methods

The study is designed as a three-center, randomized controlled trial with a 12-month intervention period. Four hundred community-dwelling (pre-)frail (Clinical Frailty Scale score 4–6) older adults (≥70 years) will be randomized in a 1:1 ratio to the intervention group (IG) or the control group (CG). The IG will receive the PromeTheus program consisting of obligatory home-based physical exercises (Weight-bearing Exercise for Better Balance) accompanied by physiotherapists and facultative counseling services (person-environment-fit, coping with everyday life, nutrition, group-based activities) delivered via existing healthcare structures (e.g., social workers, nutritionists). The CG will receive usual care and a one-time counseling session on recommendations for physical activity and nutrition. Primary outcomes assessed at months 6 and 12 are the function component of the Late-Life Function and Disability Instrument and the University of Alabama at Birmingham Life-Space Assessment. Secondary outcomes are disability, physical capacity and activity, frailty, nutritional status, falls, fear of falling, health status, and psychosocial components. Process and economic evaluations are also conducted. Primary statistical analyses will be based on the intention-to-treat principle.

Discussion

Compared to usual care, the PromeTheus program is expected to result in higher function and mobility, greater independence and lower need for care, and more participation. As the PromeTheus program draws on existing German healthcare structures, its large-scale translation and delivery will be feasible, if evidence of (cost-)effectiveness and successful implementation can be demonstrated.

Validation of a proxy-reported SARC-F questionnaire for current and retrospective screening of sarcopenia-related functional impairments

BACKGROUND

The strength, assistance walking, rise from a chair, climb stairs, and falls (SARC-F) questionnaire is a well-established instrument for screening of sarcopenia and sarcopenia-related functional impairments. As it is based on self-reporting, its use precludes patients who are unable to answer the questionnaire as a consequence of severe acute diseases or cognitive impairment. Therefore, we aimed to validate a proxy-reported version of the SARC-F for both ad-hoc as well as retrospective screening for severe sarcopenia-related functional impairments.

METHODS

Patients aged ≥60 years completed the SARC-F and performed the short physical performance battery (SPPB) at baseline (T1). Proxies in Cohort A gave a simultaneous assessment of the patients' functional status with the proxy-reported SARC-F at T1 and again, retrospectively, after 3 months (T2). Proxies in Cohort B only completed the SARC-F retrospectively at T2. The questionnaires' performances were assessed through sensitivity/specificity analyses and receiver operating characteristic (ROC) curves. For non-inferiority analyses, results of both the patient-reported and proxy-reported SARC-F were correlated with the SPPB total score as well as the results of the chair-rise test subcategory; the respective correlation coefficients were tested against each other.

RESULTS

One hundred and four patients and 135 proxies participated. Using a SPPB score < 9 points as the reference standard, the proxy-reported SARC-F identified patients at high risk for sarcopenia-related functional impairment with a sensitivity of 0.81 (ad-hoc), 0.88 (retrospective Cohort A), and 0.87 (retrospective Cohort B) as well as a specificity of 0.89 (ad-hoc), 0.78 (retrospective Cohort A), and 0.64 (retrospective Cohort B). Areas under the ROC curves were ≥ 0.9 for the ad-hoc proxy-reported SARC-F and the retrospective proxy-reported SARC-F in both cohorts. The proxy-reported SARC-F showed a non-inferior correlation with the SPPB compared with the patient-reported SARC-F for ad-hoc (P = <0.001) as well as retrospective screening for severe sarcopenia-related functional impairment in both Cohorts A (P = 0.007) and B (P = 0.026).

CONCLUSIONS

Proxy-reported SARC-F is a valid instrument for both ad-hoc as well as retrospective screening for sarcopenia-related functional impairment and could become the standard tool for evaluating this risk in older adults with severe acute disease, for example, in patients with quickly evolving haematological conditions.

[Sarcopenia-what should the orthopedist know?]

Sarcopenia - the age-associated loss of muscle function and muscle mass - is of utmost importance for older patients with degenerative and traumatic diseases of the musculoskeletal system, as it closely linked to the loss of independence and quality of life in higher age. Impairments of mobility that are highly present in this patient group accelerate the age-associated decline of muscle function and muscle mass. The diagnosis of sarcopenia relies primarily on tests of strength and function like handgrip, chair-rise test and gait speed. The measurement of muscle mass is desirable, but not mandatory. In the near future the prevention and treatment of sarcopenia has to become part of the clinical routine for older orthopedic patients. Specific modifications of physical exercise like resistance training and optimal nutrition with regard to protein intake (1.0-1.2 g/kg bodyweight per day) in combination with vitamin D supplementation are key components of sarcopenia prevention and therapy.

Development of an Electronic Tool to Assess Patient Preferences in Geriatric Polypharmacy (PolyPref)

PURPOSE

Medical decision-making in older adults with multiple chronic conditions and polypharmacy should include the individual patient's treatment preferences. We developed and pilot-tested an electronic instrument (PolyPref) to elicit patient preferences in geriatric polypharmacy.

PATIENTS AND METHODS

PolyPref follows a two-stage direct approach to preference assessment. Stage 1 generates an individual preselection of relevant health outcomes and medication regimen characteristics, followed by stage 2, in which their importance is assessed using the Q-sort methodology. The feasibility of the instrument was tested in adults aged ≥70 years with ≥2 chronic conditions and regular intake of ≥5 medicines. After the assessment with PolyPref, the patients rated the tool with regard to its comprehensibility and usability and assessed the accuracy of the personal result. Evaluators rated the patients' understanding of the task.

RESULTS

Eighteen short-term health outcomes, 3 long-term health outcomes, and 8 medication regimen characteristics were included in the instrument. The final population for the pilot study comprised 15 inpatients at a clinic for geriatric rehabilitation with a mean age of 80.6 (± 6.0) years, a median score of 28 (range 25-30) points on the Mini-Mental State Examination, and a mean of 11.6 (± 3.6) regularly taken medicines. Feedback by the patients and the evaluators revealed ratings in favor of understanding and comprehensibility of 86.7% to 100%. The majority of the patients stated that their final result summarized the most important aspects of their pharmacotherapy (93.3%) and that its ranking order reflected their personal opinion (100%). Preference assessment took an average of 35 (± 8.5) min, with the instrument being handled by the evaluator in 14 of the 15 participants.

CONCLUSION

Preference assessment with PolyPref was feasible in older adults with multiple chronic conditions and polypharmacy, offering a new strategy for the standardized evaluation of patient priorities in geriatric pharmacotherapy.

Influence of Cognitive Impairment on Rehabilitation Received and Its Mediating Effect on Functional Recovery

BACKGROUND

Cognitive impairment (CI) has been reported to negatively impact rehabilitation outcomes. Knowledge about differences in rehabilitation received in dependence of CI as a potential mediating factor is limited.

OBJECTIVE

To analyze whether CI affects amount and frequency of rehabilitation received and if associations between CI and rehabilitation outcome are mediated by the provided amount of therapy.

METHODS

Observational cohort study in ward-based geriatric rehabilitation consecutively including 373 patients (mean age 82.0±6.69 years, mean MMSE 23.66±5.31). Outcome measures were amount, frequency, and type of multi-professional therapy sessions and rehabilitation outcome assessed with the Barthel Index (BI). Cognitive status was measured with the Mini-Mental-State Examination (MMSE) classifying three patient subgroups according to cognitive status.

RESULTS

Patients with more severe CI received least total therapy hours (TTH) (MMSE < 17, 13.67±6.58 versus MMSE 17-26, 16.12±7.19 and MMSE > 26, 17.79±8.88 h, p = 0.014) and were less often included in occupational therapy (MMSE < 17, 48.9%versus MMSE 17-26, 65.5%and MMSE > 26, 71.4%, p = 0.019) and group-based physiotherapy (MMSE < 17, 73.3%versus MMSE 17-26, 88.5%and MMSE > 26, 81.2%, p = 0.027). Regression models showed that CI negatively impacted TTH (β= 0.24, p = 0.003) and rehabilitation outcome (β= 0.41, p = 0.008). In the mediation model, TTH accounted for 23.18%(p < 0.001) of the relationship between CI and rehabilitation outcome.

CONCLUSION

Cognitive impairment negatively impacted rehabilitation received. The lower TTH partly mediated the negative association between CI and rehabilitation outcome. Future research should identify specific barriers to therapy provision and optimal length, intensity, and dosage of rehabilitation programs to optimize rehabilitation outcomes in CI.

Evaluation of a new screening instrument for psychological distress in postacute rehabilitation in older person

PURPOSE

Although psychological distress has a negative impact on functional recovery, institutionalisation and mortality rates, there is typically no established procedure to screen for psychological distress in geriatric rehabilitation. The aim of the study was to evaluate a brief single-item Verbal Numerical Rating Scale (VNRS-PD) as a screening tool for psychological distress in multimorbid geriatric rehabilitation patients.

METHODS

In this cross-sectional study, N = 132 geriatric rehabilitation in-patients (M = 82 years old; 70.5% female) completed a verbal numerical rating scale (VNRS-PD) on satisfaction with their mood as well as the Hospital Anxiety and Depression Scale (HADS) and the short-form of the Geriatric Depression Scale (GDS). Based on the questionnaire data, the rehabilitation patients were classified as high or low in psychopathology. Using receiver-operating characteristic (ROC) curve analysis, optimal cutoff scores of the VNRS-PD were calculated for each questionnaire to detect significant psychological distress.

RESULTS

Between 28.8% (HADS ≥ 18) and 43.9% (GDS ≥ 6) of the sample had above-cutoff questionnaire scores. The area under the curve (AUC) of the VNRS-PD varied from 0.785 (95%-CI 0.709-0.861) (GDS ≥ 6) and 0.790 (95%-CI 0.716-0.864) (HADS ≥ 18) to 0.807 (95%-CI 0.734-0.880) (GDS ≥ 7). A score of ≤ 5 in the VNRS-PD proved to be the cutoff with an optimal trade-off between sensitivity (0.776-0.867) and specificity (0.638-0.703).

CONCLUSION

The VNRS-PD may be a suitable screening instrument to detect patients with psychological distress in inpatient geriatric rehabilitation for and to initiate further diagnostics within a graduated psychodiagnostic scheme. This first step may help to identify older patients with psychological distress and mental disorders, to initiate targeted interventions. Further research is needed to replicate these findings in a larger sample.

Detecting Impending Malnutrition of (Pre-) Frail Older Adults in Domestic Smart Home Environments

Malnutrition is a well-known risk factor for deteriorated physical function, disability and loss in independence in older adults. An unintended loss in body weight of more than 5% in 3 months is one indicator for malnutrition. In this study we examined the relationship between meal preparation time, hand grip strength, and body weight in order to map impending nutritional problems using ambient sensors. Data were collected in the domestic environments of 20 (pre-) frail older adults aged 85.75 y (Standard Deviation: 5.19 y) over 10-months of observation. Collecting included physical function and nutritional status of the participants and meal preparation time by a combination of motion and power sensor events. Analysis was done by rank correlation of hand grip strength, body weight, and meal preparation time. Ten participants aged 85.1 years (Standard Deviation: 4.6 y) were included. The results show a significant correlation (≥0.99) of the meal preparation time with the hand grip strength. This result validated the meal preparation time as a suitable measure for analysing the correlation between meal preparation time and body weight, and a significant correlation (≥0.99) found. Hence the meal preparation time could be used as an indicator for malnutrition. However, causalities have to be conducted by further clinical studies.

The COVID rehabilitation paradox: why we need to protect and develop geriatric rehabilitation services in the face of the pandemic

Older multi-morbid persons often fall seriously ill due to COVID-19. To be able to participate in a social life again, they often need special rehabilitation measures. Geriatric rehabilitation is a multi-professional service geared to these needs. Paradoxically, however, capacities in geriatric rehabilitation are currently being reduced despite increasing demand. The reasons are manifold and are not only due to the current situation. This article highlights the current situation leading to the COVID rehabilitation paradox and shows ways to learn from it for the future.

Experts' preferences for sarcopenia outcomes: a discrete-choice experiment from a working group of the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) in collaboration with the European Union of Geriatric Medicine Society (EUGMS)

BACKGROUND AND AIMS

To assess experts' preference for sarcopenia outcomes.

METHODS

A discrete-choice experiment was conducted among 37 experts (medical doctors and researchers) from different countries around the world. In the survey, they were repetitively asked to choose which one of two hypothetical patients suffering from sarcopenia deserves the most a treatment. The two hypothetical patients differed in five pre-selected sarcopenia outcomes: quality of life, mobility, domestic activities, fatigue and falls. A mixed logit panel model was used to estimate the relative importance of each attribute.

RESULTS

All sarcopenia outcomes were shown to be significant, and thus, important for experts. Overall, the most important sarcopenia outcome was falls (27%) followed by domestic activities and mobility (24%), quality of life (15%) and fatigue (10%).

DISCUSSION AND CONCLUSION

Compared to patient's preferences, experts considered falls as a more important outcome of sarcopenia, while the outcomes fatigue and difficulties in domestic activities were considered as less important.

[Clinical importance of the detection of frailty]

Frailty ist ein multidimensionales geriatrisches Syndrom, das durch einen Verlust an individueller Reservekapazität und eine erhöhte Vulnerabilität gegenüber internen und externen Stressoren gekennzeichnet ist. Frailty ist mit einem erhöhten Risiko für Stürze und einen Autonomieverlust sowie mit einer erhöhten Mortalität verbunden. Die Identifikation von Personen, die eine Frailty aufweisen, kann ein umfangreiches geriatrisches Assessment triggern und gezielte Therapieangebote begründen. Darüber hinaus können durch die Erfassung von Frailty jene Patient*innen identifiziert werden, die ein erhöhtes Risiko für ungünstige Behandlungsverläufe haben. Für die Erfassung von Frailty gibt es eine unübersichtliche Zahl an Instrumenten, wobei nur eine eingeschränkte Auswahl dieser Instrumente in einer deutschen Version vorliegt. Die Wahl des Instruments sollte sich am klinischen Setting und den vorhandenen Ressourcen orientieren.

Construct Validity, Test-Retest Reliability, Sensitivity to Change, and Feasibility of the Patient-Specific Functional Scale in Acutely Hospitalized Older Patients With and Without Cognitive Impairment

BACKGROUND AND PURPOSE

The Patient-Specific Functional Scale (PSFS) as an individualized patient-reported outcome measure may allow to assess limitations and changes in self-determined functional activities most important to an older patient in the acute care setting. However, its clinimetric properties have not yet been evaluated in these patients. The study aimed to investigate the construct validity, test-retest reliability, sensitivity to change, and feasibility of the PSFS in acutely hospitalized older patients with and without cognitive impairment (CI).

METHODS

The clinimetric properties of the PSFS were investigated by secondary data analysis from a prospective observational cohort study examining physical activity and mobility in acutely hospitalized older patients. In this analysis, 120 older patients-83.0 (6.4) years-with (Mini-Mental State Examination [MMSE] 18-23, n = 52) and without CI (MMSE ≥24, n = 68) receiving early multidisciplinary geriatric rehabilitation in acute care were included. Construct validity was assessed by Spearman correlations (rs) with the Activity-specific Balance Confidence Scale (ABC-6), Short Falls Efficacy Scale-International (Short FES-I), EuroQoL-5 Dimensions (EQ-5D), Short Physical Performance Battery (SPPB), de Morton Mobility Index (DEMMI), and Barthel Index (BI); test-retest reliability within 24 hours by intraclass correlation coefficients (ICCs); sensitivity to change by standardized response means (SRMs) calculated for treatment effects, and feasibility by completion rates/times and floor/ceiling effects.

RESULTS

The PSFS showed fair to moderate correlations with all construct variables in patients with CI (rs = 0.31 to 0.53). In patients without CI, correlations were fair for the ABC-6, FES-I, EQ-5D, and BI (rs = |0.27 to 0.36|), but low for the SPPB and DEMMI (rs = -0.04 to 0.14). Test-retest reliability (both: ICC = 0.76) and sensitivity to change (CI: SRM = 1.10, non-CI: SRM = 0.89) were excellent in both subgroups. Excellent feasibility was documented by high completion rates (>94%), brief completion times (<8 min), and no floor/ceiling effects in both subgroups.

CONCLUSIONS

The PSFS has adequate clinimetric properties for assessing patient-specific functional limitations and changes in acutely hospitalized older patients with and without CI. It might be an appropriate complement to traditional functional scales to enhance patient-centeredness in clinical geriatric assessment.

[COVID-19 in old age-The geriatric perspective]

Predominantly the older population is affected by a severe course of COVID-19. The mortality of hospitalized patients with COVID-19 above the age of 80 years is up to 54% in international studies. These observations indicate the necessity to highlight the geriatric perspective on this disease. The diagnostics and treatment of COVID-19 do not differ between younger and older patients but atypical symptoms should be expected more frequently in old age. Older subjects show an increased need for rehabilitation after COVID-19. Paradoxically, increasing rehabilitation demands go along with a reduced availability of geriatric rehabilitation options, the latter being a consequence of closure or downsizing of rehabilitation departments during the pandemic. In general, measures of isolation and quarantine should be diligently balanced as the health and emotional consequences of such measures may be severe in older persons. In light of the poor prognosis of older COVID-19 patients, advanced care planning becomes even more relevant. Caregivers and physicians should be encouraged to compose advanced care directives that also reflect the specific circumstances of COVID-19. Fortunately, current data suggest that the effectiveness of the vaccination with the mRNA-vaccines approved in Germany may be equally high in older compared to younger persons.

[Psychosocial effects of the pandemic on staff and residents of nursing homes as well as their relatives-A systematic review]

Hintergrund

Die COVID-19-Pandemie stellt Bewohner von Altenpflegeeinrichtungen, deren Angehörige bzw. Besucher ebenso wie Mitarbeitende vor große Herausforderungen. Viruseindämmende Maßnahmen wirken sich stark auf das Wohlbefinden der betroffenen Personengruppen aus.

Material und Methode

Systematische Literatursuche nach Studien zu psychosozialen Folgen der Pandemie für Bewohner, deren Angehörige bzw. Besucher sowie Mitarbeitende und Zusammenführung der Ergebnisse mittels narrativer Synthese.

Ergebnisse

Es wurden 756 Studien gesichtet, davon 15 Arbeiten eingeschlossen. Die Daten wurden zwischen Februar und Juni 2020 mit Teilnehmenden aus 14 Ländern erhoben. Es wurden v. a. Einsamkeit, Trauer und Depressivität, aber auch Angst, als häufige Reaktionen der Bewohner auf die Kontakt- und Besuchsrestriktionen berichtet. Bewohner mit kognitiven Einschränkungen litten stärker unter den Auswirkungen, auch wenn es gegenteilige Hinweise gibt. Angehörige bzw. Besucher berichteten ebenfalls von einer Zunahme ihrer Einsamkeit und einer reduzierten Lebensqualität. In den Befragungen der Mitarbeitenden schildern diese Angst vor einer Infektion sowohl bei sich als auch bei den Bewohnern. Infizierte Mitarbeitende in den USA äußerten Wut darüber, nicht ausreichend geschützt worden zu sein. Darüber hinaus berichteten Mitarbeitende von einer erheblichen Mehrbelastung.

Schlussfolgerung

Infolge der Pandemie und der ergriffenen Maßnahmen wurden negative psychosozialen Folgen bei Bewohnern, deren Angehörigen bzw. Besuchern und den Mitarbeitenden berichtet. Die abzuleitenden Unterstützungsbedarfe der 3 Personengruppen sind unterschiedlich und sollten bei zukünftigen Maßnahmen hinsichtlich der Pandemie stärker mitevaluiert werden.

Pan-European Study on Functional and Medical Recovery and Geriatric Rehabilitation Services of Post-COVID-19 Patients: Protocol of the EU-COGER Study

OBJECTIVES

There is insufficient knowledge about the functional and medical recovery of older people infected with SARS-CoV-2. This study aims to gain insight into the course of functional and medical recovery of persons who receive geriatric rehabilitation (GR) following SARS-CoV-2 infection across Europe. Special attention will be paid to the recovery of activities of daily living (ADL) and to the GR services offered to these patients.

DESIGN

A multi-center observational cohort study.

SETTING AND PARTICIPANTS

This study will include several European countries (EuGMS member states) each providing at least 52 comparable routine datasets (core dataset) of persons recovering from a SARS-CoV-2 infection and receiving geriatric rehabilitation. The routine data will be anonymously collected in an online CASTOR database. The ethical regulations of each participating country will be followed.

PRIMARY OUTCOME

ADL functioning.

SECONDARY OUTCOMES

length of stay, discharge destination, hospital readmission and mortality. Other variables that will be collected are quality of life, treatment modalities, complications, cognition, frailty, mood/anxiety, BMI, nutrition and pain. All variables will be reported at admission and compared with follow-up scores (discharge, 6 weeks and 6 months follow-up).

CONCLUSION

This study will explore the effect of geriatric rehabilitation on post-COVID-19 patients, especially on ADL recovery, and the variety of geriatric rehabilitation services across Europe. Information from this study may help improve recovery of older persons infected with SARS-CoV-2 and improve geriatric rehabilitation services in the ongoing COVID-19 pandemic.

Will We Do If We Can? Habitual Qualitative and Quantitative Physical Activity in Multi-Morbid, Older Persons with Cognitive Impairment

This study aimed to identify determinants of quantitative dimensions of physical activity (PA; duration, frequency, and intensity) in community-dwelling, multi-morbid, older persons with cognitive impairment (CI). In addition, qualitative and quantitative aspects of habitual PA have been described. Quantitative PA and qualitative gait characteristics while walking straight and while walking turns were documented by a validated, sensor-based activity monitor. Univariate and multiple linear regression analyses were performed to delineate associations of quantitative PA dimensions with qualitative characteristics of gait performance and further potential influencing factors (motor capacity measures, demographic, and health-related parameters). In 94 multi-morbid, older adults (82.3 ± 5.9 years) with CI (Mini-Mental State Examination score: 23.3 ± 2.4), analyses of quantitative and qualitative PA documented highly inactive behavior (89.6% inactivity) and a high incidence of gait deficits, respectively. The multiple regression models (adjusted R² = 0.395–0.679, all p < 0.001) identified specific qualitative gait characteristics as independent determinants for all quantitative PA dimensions, whereas motor capacity was an independent determinant only for the PA dimension duration. Demographic and health-related parameters were not identified as independent determinants. High associations between innovative, qualitative, and established, quantitative PA performances may suggest gait quality as a potential target to increase quantity of PA in multi-morbid, older persons.

Validation of the interview-based life-space assessment in institutionalized settings (LSA-IS) for older persons with and without cognitive impairment

BACKGROUND

Self-reported life-space assessment methods so far focus on community-dwelling persons, with a lack of validated assessment methods for institutionalized settings. This study evaluated construct validity, test-retest reliability, sensitivity to change, and feasibility of a new Life-Space Assessment for Institutionalized Settings (LSA-IS) in geriatric patients.

METHODS

Psychometric properties of the LSA-IS in 119 hospitalized geriatric patients (83.0 ± 6.2 years) with and without cognitive impairment (CI) [Mini-Mental State Examination: 22.4 ± 4.9 scores] were evaluated within a comprehensive validation design. For the total group and subgroups according to cognitive status, construct validity was assessed by calculating Spearman's rank correlation coefficients (rho) with established construct variables, test-retest reliability by intra-class correlation coefficients (ICCs), sensitivity to change by standardized response means (SRMs) calculated for effects of early ward-based rehabilitation during hospital stay.

RESULTS

The LSA-IS (total score) demonstrated good test-retest reliability (ICC = .704), and large sensitivity to change (SRM = .806), while construct validity was small to high indicated by significant correlations of the LSA-IS to construct variables (rho = .208-716), depending on relative construct association. On average results of LSA-IS sub-scores confirmed results of the total score. Subgroups according to cognitive status did not differ for most analyzed variables. A completion rate of 100% and a completion time of 3.2 ± 1.2 min documented excellent feasibility.

CONCLUSIONS

The interview-based LSA-IS has proven to be valid, reliable, sensitive, and feasible in hospitalized, multi-morbid, geriatric patients with and without CI documenting good psychometric properties for institutionalized settings.
