Integrale of simpele frailty meting: de context moet leidend zijn

Dr. Gobbens en zijn promotor en co-promotoren kunnen om meerdere redenen gefeliciteerd worden met het proefschrift over een integrale benadering van het begrip frailty. De auteur en zijn begeleider hebben een serieuze inspanning geleverd om het begrip frailty vanuit een andere context te bezien, namelijk die van het integrale menselijke functioneren. Dat dit vanuit de Universiteit Tilburg gebeurt, met een rijke traditie in de sociale wetenschappen, lijkt haast vanzelfsprekend, maar is toch een belangrijke toevoeging. De context is immers in hoge mate bepalend voor het onderzoek aan het brede begrip frailty. Het kon eigenlijk dan ook niet anders dan dat een Tilburgs frailty proefschrift de sociale en psychische dimensie zou toevoegen aan het fysieke domein, dat tot nu toe dominant was in de frailty concepten. Deze aanpak past bovendien uitstekend bij de brede oriëntatie van de promotor, prof dr. Jos Schols. Aan het werk herkent men de meester

De variatie in ouder worden begrijpen en beïnvloeden, dat is onze drijfveer. Een overzicht van het onderzoek van de afdeling Geriatrie van het UMC St Radboud

Bespreking onderzoek De kansen die de grote variatie tussen ouderen biedt, bijvoorbeeld die tussen de zeer succesvol oud geworden Hendrikje van Andel-Schipper (115 jaar) en de gemiddelde verpleeghuispatiënt, vormen de drijfveer voor ons onderzoek. Niet zozeer achteruitgang, maar veel meer heterogeniteit in de wijze waarop de achteruitgang optreedt kenmerkt veroudering

Cerebrospinal Fluid Biomarkers in Diagnosing Alzheimer's Disease in Clinical Practice: An Illustration with 3 Case Reports

Analysis of the brain specific biomarkers amyloid β42 (Aβ42) and total tau (t-tau) protein in cerebrospinal fluid (CSF) has a sensitivity and specificity of more than 85% for differentiating Alzheimer's Disease (AD) from non-demented controls. International guidelines are contradictory in their advice on the use of CSF biomarkers in AD diagnostics, resulting in a lack of consistency in clinical practice. We present three case reports that illustrate clinical practice according to the Dutch and European guidelines and portray the value of CSF biomarker analysis as an add-on diagnostic to the standard diagnostic workup for AD

Why did an effective Dutch complex psycho-social intervention for people with dementia not work in the German healthcare context? Lessons learnt from a process evaluation alongside a multicentre RCT

Contains fulltext : 97517.pdf (publisher's version ) (Open Access)Background The positive effects of the Dutch Community Occupational Therapy in Dementia programme on patients' daily functioning were not found in a multicentre randomised controlled trial (RCT) in Germany. Objectives To evaluate possible effect modification on the primary outcome within the German RCT with regard to (1) participant characteristics, (2) treatment performance and (3) healthcare service utilisation; and (4) to compare the design and primary outcome between the German and the original Dutch study. Methods (1) The impact of participant baseline data on the primary outcome was analysed in exploratory ANCOVA and regression analyses. (2) Therapists completed questionnaires on context and performance problems. The main problems were identified by a qualitative content analysis and focus-group discussion. Associations of the primary outcome with scores of participant adherence and treatment performance were evaluated by regression analysis. (3) Utilisation rates of healthcare services were controlled for significant group differences. (4) Differences in the Dutch and German study design were identified, and the primary outcome was contrasted at the item level. Results (1) Participant characteristics could not explain more than 5% of outcome variance. (2) The treatment performance of some active intervention components was poor but not significantly associated with the primary outcome. (3) There were no significant group differences in the utilisation of healthcare resources. (4) In contrast to the Dutch waiting-control group, the active intervention in the German control group may have reduced group differences in the current RCT. The German patients demonstrated a higher independence at baseline and less improvement in instrumental activities of daily living. Conclusion The differences in outcome may be explained by a more active control treatment, partially poor experimental treatment and less room for improvement in the German sample. Future cross-national transfers should be prepared by pilot studies assessing the applicability of the intervention and patient needs specific to the target country.

Het Ogilvie-syndroom bij oudere patiënten met multiproblematiek

Twee patiënten presenteren zich met het Ogilvie-syndroom, een acute intestinale pseudo-obstructie zonder mechanische obstructie. Bij beide patiënten was er sprake van multi-problematiek met infectie, elektrolietstoornissen en functionele achteruitgang. Dit ziektebeeld komt vooral voor bij zieke patiënten vanaf 60 jaar met multimorbiditeit die in het ziekenhuis of verpleeghuis verblijven. Met de vergrijzing zal de incidentie van dit ziektebeeld waarschijnlijk toenemen, met name bij de kwetsbare oudere patiënt. De precieze pathofysiologie is onbekend, maar er zijn in de literatuur aanwijzingen voor een multicausaal model dat autonome disregulatie van het colon veroorzaakt. Vroege herkenning en adequate behandeling kan het risico op complicaties en overlijden sterk doen verminderen, afhankelijk van de onderliggende comorbiditeit

Development of the Nurses' Observation Scale for Cognitive Abilities (NOSCA)

Background. To assess a patient's cognitive functioning is an important issue because nurses tailor their nursing interventions to the patient's cognitive abilities. Although some observation scales exist concerning one or more cognitive domains, so far, no scale has been available which assesses cognitive functioning in a comprehensive way. Objectives. To develop an observation scale with an accepted level of content validity and which assesses elderly patients' cognitive functioning in a comprehensive way. Methods. Delphi technique, a multidisciplinary panel developed the scale by consensus through four Delphi rounds (>70% agreement). The International Classification of Functioning/ICF was used as theoretical framework. Results. After the first two Delphi rounds, the panel reached consensus about 8 cognitive domains and 17 sub domains. After two other rounds, 39 items were selected, divided over 8 domains and 17 sub domains. Discussion. The Nurses' Observation Scale Cognitive Abilities (NOSCA) was successfully designed. The content validity of the scale is high because the scale sufficiently represents the concept of cognitive functioning: the experts reached a consensus of 70% or higher on all domains and items included; and no domains or items were lacking. As a next step, the psychometric qualities of the NOSCA will have to be tested

A Simple and Practical Index to Measure Dementia-Related Quality of Life

AbstractBackgroundResearch on new treatments for dementia is gaining pace worldwide in an effort to alleviate this growing health care problem. The optimal evaluation of such interventions, however, calls for a practical and credible patient-reported outcome measure.ObjectivesTo describe the refinement of the Dementia Quality-of-life Instrument (DQI) and present its revised version.MethodsA prototype of the DQI was adapted to cover a broader range of health-related quality of life (HRQOL) and to improve consistency in the descriptions of its domains. A valuation study was then conducted to assign meaningful numbers to all DQI health states. Pairs of DQI states were presented to a sample of professionals working with people with dementia and a representative sample of the Dutch population. They had to repeatedly select the best DQI state, and their responses were statistically modeled to obtain values for each health state.ResultsIn total, 207 professionals working with people with dementia and 631 members of the general population completed the paired comparison tasks. Statistically significant differences between the two samples were found for the domains of social functioning, mood, and memory. Severe problems with physical health and severe memory problems were deemed most important by the general population. In contrast, severe mood problems were considered most important by professionals working with people with dementia.DiscussionThe DQI is a simple and feasible measurement instrument that expresses the overall HRQOL of people suffering from dementia in a single meaningful number. Current results suggest that revisiting the discussion of using values from the general population might be warranted in the dementia context

Predictive validity of a two-step tool to map frailty in primary care

Background EASY-Care Two step Older people Screening (EASY-Care TOS) is a stepped approach to identify frail older people at risk for negative health outcomes in primary care, and makes use of General Practitioners’ (GPs) readily-available information. We aimed to determine the predictive value of EASY-Care TOS for negative health outcomes within the year from assessment. Methods A total of 587 patients of four GP practices in and around Nijmegen (The Netherlands) consented to participate in a longitudinal primary care registry based cohort study. Participants’ frailty was judged by their GP following the EASY-Care TOS procedure and by a Comprehensive Geriatric Assessment (CGA) at baseline. After one year health outcomes of the participants were measured by reassessment with the EASY-Care TOS procedure. Results Follow up information was available for 520 of 587 participants. In the non-frail group 9 % showed any negative health outcomes (death, ADL decline, institutionalisation, too ill to undergo assessment), against 30 % in the frail group (95 % confidence interval of the difference (CI): 14 %–28 %). Area under the receiver operating curve (AUC) of the EASY-Care TOS frailty judgement for a composite of negative health outcomes mentioned was 0.67 (95 % CI: 0.62-0.73). Compared with discrimination on the basis of age, sex and GP practice (AUC 0.70), adding EASY-Care TOS frailty judgement increased the AUC to 0.75 (+0.05, p = 0.02). The AUC on the basis of a full CGA is almost comparable to the AUC of the model with age, sex, and frailty judgement with EASY-Care TOS: 0.76 (+0.07, p = 0.005). Conclusions GPs applying the EASY-Care TOS procedure, where they only perform additional assessment when they judge this as necessary, can predict negative health outcomes in their older populations efficiently and almost as accurately as a complete specialist CGA
