Characterization of patients admitted to specialized geriatric acute care hospital units with the German version of the Standardized Evaluation and Intervention for Seniors at Risk (SEISAR) screening-instrument: a cross-sectional study.

BACKGROUND: The Standardized Evaluation and Intervention for Seniors at Risk (SEISAR) screening tool records major geriatric problems, originally applied in the emergency department. Particularly, the distinction of compensated and uncompensated problems is an interesting and new approach. Therefore, we translated the SEISAR in German language and used it to characterize patients in specialized geriatric hospital wards in Germany and to gather initial experience regarding its usability and practicability. METHODS: The tool was translated by three independent specialists in geriatric medicine and backtranslated for quality-assurance by a non-medical English native speaker. In a second step, 8 acute care geriatric hospital departments used the translated version to characterize all consecutive patients admitted over a period of one month between December 2019 and May 2020 at time of admission. RESULTS: Most of the 756 patients (78%) lived in an own apartment or house prior to hospital admission. Participants had on average 4 compensated and 6 uncompensated problems, a Barthel-Index of 40 pts. on admission with a median increase of 15 points during hospital stay, and a median length of stay of 16 days in the geriatric hospital department. CONCLUSION: SEISAR is an interesting standardized brief comprehensive geriatric assessment tool for the identification of compensated and uncompensated health problems in older persons. The data of this study highlights the number, variability, and complexity of geriatric problems in patients treated in specialized acute care geriatric hospital wards in Germany.

[Effectiveness of geriatric rehabilitation in the oldest old: evaluation of South German observational data]. / Wirksamkeit geriatrischer Rehabilitation bei Hochbetagten : Eine Auswertung süddeutscher Versorgungsdaten.

BACKGROUND: Geriatric rehabilitation might be the only way for the very old to maintain their participation in social life, since in many cases self care, everyday skills and basic activities of daily living can only be recovered by an integrative treatment approach using a multiprofessional team setting. At the same time limited financial resources in health care have to be considered to make appropriate allocation decisions in geriatric rehabilitation. PURPOSE: The goal of this work was to determine whether chronological age is a limiting factor for functional outcome in geriatric rehabilitation. MATERIALS AND METHODS: Data from the state of Baden-Württemberg (KODAS data set) from the years 2005-2011 for nonagenarians and data for centenarians from the Geriatrics in Bavaria database (GiB-DAT) project from the years 2003-2011 were compared to the data of the younger seniors undergoing geriatric rehabilitation. For the KODAS data collection, 31 geriatric rehabilitation clinics in Baden-Württemberg were involved. The GiB-DAT project included 59 geriatric rehabilitation clinics in Bavaria. Both databases compare the results of the geriatric assessment at the beginning and at the end of geriatric rehabilitation. RESULTS: The analyzed data are presented with regard to the functional outcome in the very elderly and are discussed with respect to policy implications.

Geriatric rehabilitation after hip fracture. Role of body-fixed sensor measurements of physical activity.

BACKGROUND: The demand for geriatric rehabilitation will drastically increase over the next years. It will be increasingly important to demonstrate the efficacy and effectiveness of geriatric rehabilitation. One component is the use of objective and valid assessment procedures. These should be understandable to patients, relevant for goal attainment, and able to document change. A number of currently used physical capacity measures have floor effects. The use of body-fixed sensor technology for monitoring physical activity is a possible supplement for the assessment during geriatric rehabilitation to overcome floor effects and directly monitor improvement of mobility as a component of geriatric rehabilitation in many patients. METHODS: The observational study with a pre-post design examined 65 consecutive geriatric hip fracture inpatients. Measurements were performed on admission and 2 weeks later. The capacity measures included gait speed, chair rise time, a balance test, 2-Minute-Walk test and the Timed-Up-and-Go test. Physical activity was measured over 9 h using body-fixed sensor technology and expressed as cumulated walking and walking plus standing (time on feet). RESULTS: Body-fixed sensors allowed direct measurement of physical activity in all patients available for testing. Cumulated walking and standing (time on feet) increased from a median 83.6 to 102.6 min. Cumulated walking increased from a median 7.0 to 16.3 min. The comparison with the physical capacity measures demonstrated a modest to fair correlation (rs = 0.455 and 0.653). This indicates that physical capacity measures are not the same construct as physical activity. CONCLUSION: Body-fixed sensor-based assessment of physical activity was feasible even in geriatric patients with severe mobility problems and decreased the number of patients with missing data both on admission and 2 weeks later. Body-fixed sensor data documented change in activity level.

Physical activity of moderately impaired elderly stroke patients during rehabilitation.

In older adults, physical activity (PA) is promoted for public health preventive effort. It is also a major target in the rehabilitation process. Existing assessment tools in the clinical routine do not include any aspects of PA or participation and are often prone to floor or ceiling effects. The aim of this study was to document the process of rehabilitation by activity monitoring without floor or ceiling effects. Ninety-two stroke patients of a geriatric rehabilitation unit (mean age 82 years, ±6.21 years, 61% women) were included in an observational study to assess physical capacity (balance, chair rise, gait speed) and PA at admission and two weeks thereafter. PA was measured through an ambulatory activity monitor based on accelerometers and gyroscopes and showed no floor or ceiling effects. Floor effects were however documented for measures of physical capacity (admission 5-11%; follow-up 2-9%) and ceiling effects were registered for the balance test (admission 17.4%; follow-up 22.8%). Improvements were documented for measures of physical capacity as well as for PA (all p < 0.001). We conclude that the assessment of PA by activity monitoring is a valuable measure to document objectively the process of rehabilitation without floor or ceiling effects.

[Maintenance of health and relief for caregivers of elderly with dementia by using "initial case management": experiences from the Lighthouse Project on Dementia, Ulm, ULTDEM-study]. / Gesunderhaltung und Entlastung pflegender Angehöriger von Demenzkranken durch ein "initiales Case Management": Erfahrungen aus dem Ulmer Leuchtturmprojekt Demenz (ULTDEM-Studie).

BACKGROUND: When facing the well-known demographic development with an increasing number of people suffering from dementia, there is a need of programmes to support nursing relatives and care at home. Many support services have been established in the past few years but they are rarely used by the relatives and the patients. The purpose of the Lighthouse Project Ulm (ULTDEM Study) was to prove the effectiveness of a single advisory approach in order to provide support services after care level classification and to relieve the burden placed on relatives caring for family members suffering from dementia ("initial case management"). METHODS: The ULTDEM Study is a prospective, open, randomized, controlled, interventional study with different parallel outcome measures (burden of caring, quality of life and mood). After the randomization, the interventional group was given comprehensive, individual advice about available treatment possibilities for dementia patients. Control group participants received standard treatment. Inclusion criteria were application of a care level (0 or 1) as well as dementia diagnosis. All participants (patients/relatives) underwent an initial and a 6 month comprehensive assessment. RESULTS: Our results show that a single advisory approach does not lead to a significant difference in outcome measures in interventional and control groups. Those tendencies described have to be interpreted as clinically not relevant. Although utilization of support services increases, it remains similar in both study groups. A confirmatory interpretation has not been possible due to a lack of adjustment to the findings regarding multiple testing and an insufficient degree of recruitment. Possible causes will be discussed such as premature intervention during the course of the disease, a lack of intervention blinding, recruitment bias and lack of an influence on adherence with regard to the use of support services. IMPLICATIONS: The study demonstrates that there is a substantial information deficit for persons affected by dementia and their relatives. Innovative ways still have to be developed to ensure that this information actually reaches the target audience.

Co-occurrence of parkinsonism and dementia in clinical practice: relevant differential diagnoses.

Co-occurrence of parkinsonism and dementia is commonly observed in the aging population. This narrative review gives an overview of disorders regularly presenting with these symptoms, e.g., idiopathic Parkinson disease with dementia, dementia with Lewy bodies, progressive supranuclear palsy, corticobasal degeneration syndrome, vascular cognitive impairment, drug-induced parkinsonism, and normal-pressure hydrocephalus. Both a thoroughly performed medical history and a comprehensive clinical examination can narrow down relevant differential diagnoses. Characteristic clinical and neuropsychological features are highlighted, including cognitive screening strategies. Neurophysiological and neuropathological aspects of the disorders are briefly discussed to give a better understanding of treatment options.

[Gait changes as an early indicator of dementia]. / Gangveränderungen als Frühindikator einer Demenz.

Gait disorders are more common in dementia than in the context of the physiological aging process. Prevalence of dementia-associated gait disturbances depends on the type of dementia and the severity of cognitive impairment. While in vascular dementia gait abnormalities are often clinically apparent at early disease stages, Alzheimer's disease patients usually have stable gait until late disease stages. With up-to-date ''brain-imaging" methods, it has been demonstrated that people suffering from dementia are more dependent on cortical activity in order to maintain gait stability in complex situations. When dysfunction of the frontal or temporal lobes occurs, allocation of these resources may no longer be sufficient. Dual-task paradigms are useful to test such resources. It has been shown in early Alzheimer's disease patients that, if the demand of attention exceeds available capacities, quantitative gait changes occur. Relevant parameters seem to be, e.g., walking speed and stride-time variability. Quantitative assessment of gait dysfunction in dementia may, thus, have the potential to serve as a trait marker.

[Recommendation of an assessment protocol to describe geriatric inpatient rehabilitation of lower limb mobility based on ICF: an interdisciplinary consensus process]. / Empfehlungen für die Durchführung des motorischen Assessments der unteren Extremität zur ICF-basierten Verlaufsbeurteilung der Mobilität in der stationären geriatrischen Rehabilitation: Bericht eines interdisziplinären Konsensusprozesses.

Because of the growing demand of geriatric rehabilitation, objective and clear indication decisions are needed with respect to limited financial resources. The aim of an interdisciplinary consensus group was to critically evaluate the most commonly used tests of functional performance of the lower limbs and to recommend useful tests to document progress of inpatient rehabilitation. Assessment of standing, walking, walking with a dual-task, sit-to-stand transfer, lying-to-sit-to-stand transfer, and stair climbing were recommended to document functional performance of the lower limbs and to describe rehabilitation targets. Future research is needed, because reasonably validated assessment tools do not exist for all of these domains. In addition to a standardized assessment of physical capacity, physical activity and participation with regard to the International Classification of Functioning, Disability, and Health (ICF) context have to be assessed. Body fixed sensors seem to be a promising assessment tool to objectively document progress in rehabilitation.

[Effectiveness of special stroke units in treatment of acute stroke]. / Wirksamkeit von speziellen Schlaganfalleinrichtungen (Stroke Units) in der Behandlung des akuten Schlaganfalls.

BACKGROUND: In Germany the implementation of specialized wards for the care of stroke patients is proposed. However, which type of organized inpatient stroke unit care is most effective and which group of patients will benefit most remains unclear. METHODS: Based on the analyses of the Stroke Unit Trialists' Collaboration this paper reports results of randomized and quasi-randomized trials that compared organized inpatient (stroke unit) care with contemporary conventional care. The primary analyses examined death, dependency and institutionalization. Secondary outcome measures included patient quality of life, patient and carer satisfaction and length of stay in hospital and/or institution. RESULTS: The analysis of twenty trails with 3864 patients showed a reduction in the rate of deaths in the stroke unit group as compared with the control group (OR 0.83, 95% CI 0.71-0.97). The odds of death or institutionalized care were lower (OR 0.76, 95% CI 0.65-0.90) as were death or dependency (OR 0.75, 95% CI 0.65-0.87). The results were independent of patient age, sex, stroke severity, and type of stroke unit organization. CONCLUSION: Organized care in stroke units resulted in benefits for stroke patients with regard to survival, independence, and probability of living at home. However, these results refer exclusively to Anglo-American and Scandinavian trials. German stroke unit services are organized in a different way. No data about the effectiveness of the German model is yet available.

Stereoselective HPLC-assay for citalopram and its metabolites.

The racemic selective serotonin reuptake inhibitor citalopram (CIT) is increasingly used for depressive disorders. As both enantiomers of CIT differ in pharmacologic activity and demethylated metabolites might contribute to the antidepressent action of CIT, a stereoselective assay for all active compounds is needed, but will require that pharmacokinetic/pharmacodynamic relationships be investigated. A stereoselective high-performance liquid chromatography (HPLC)-assay (Chirobiotic V column) with UV-detection (lambda = 240 nm) for R- and S-CIT as well as both enantiomers of desmethyl(DM)-CIT and didesmethyl(DDM)-CIT was developed. The calibration range was linear from 5 to 200 ng/mL and the lower limit of detection averaged 2 ng/mL. Based on three quality controls (10, 75, and 150 ng/mL) the intraday and interday coefficients of variation ranged from 1.3% to 9.0% for CIT and from 2.2% to 10.3% for DM-CIT and DDM-CIT. The assay was used to analyze the trough steady state plasma levels of all 6 agents in 16 elderly patients treated daily with 20 to 40 mg CIT. For the dose of 20 mg (n = 14) mean values +/- SD of R- (and S-CIT) averaged 36.2+/-15.0 (27.4+/-13.1) ng/mL, respectively (mean R/S-ratio: 1.4+/-0.4), for R- (and S-DM-CIT) 7.2+/-3.1 (7.7+/-3.8) ng/mL, respectively (R/S-ratio: 1.0+/-0.3) whereas DDM-CIT was only detectable as R-enantiomer in 8 cases (13.2+/-12.1 ng/mL; range: 2.2-36.2 ng/mL). Significant (p < 0.01) linear correlations could be found between both enantiomers of CIT and DM-CIT as well as between parent drug and primary metabolite for the R-enantiomers. Apparently R/S- and metabolic ratios increased with dose; this might indicate that stereoselective disposition of CIT and DM-CIT is concentration-dependent. The present assay allows a rapid, sensitive, and reliable stereoselective determination of CIT and its (active) metabolites which can be applied for assessing pharmacokinetic parameters and evaluating putative relationships to clinical (side) effects.
