First Evidence on the Validity of the Complexity Index Derived from the Resident Assessment Instrument for Home Care in Home Care Patients.

OBJECTIVES: Recently, a Complexity Index (CI), based on the multidimensional complexity model and derived from the Resident Assessment Instrument for Home Care (interRAI HC) was proposed as a decision-support tool to help frontline health care professionals in their clinical evaluation to identify and analyze complex situations. This study aims to test the CI: (1) concurrent validity with another measure of complexity (ie, the COMID), (2) convergent validity with related constructs assessed by interRAI HC scales (eg, depression), (3) divergent validity (comparison between CI-COMID and scales-COMID correlations), and (4) predictive validity on coordination meetings. DESIGN: A cross-sectional observational design was used for a secondary analysis of interRAI HC and COMID data collected in routine home care nursing practice (July-December 2021). SETTING AND PARTICIPANTS: Participants were community-dwelling adults receiving home care, with full interRAI HC and COMID assessments (N = 3533). METHODS: Correlational analyses were conducted to test the concurrent validity of the CI (with the COMID) and the convergent and divergent validity of the CI (with interRAI HCSwitzerland scales, eg, Depression Rating Scale, Method for Assigning Priority Levels, and a Frailty Index). A receiver operating characteristic (ROC) analysis was conducted to test the discriminative ability of CI on specific professional team coordination meetings. RESULTS: Results showed that the CI correlated positively and strongly with the COMID (ρ = 0.691, P < .001, concurrent validity), positively with all the tested scales (P < .001, convergent validity), whereas the CI-COMID correlation was higher than the interRAI HC scales-COMID correlations (divergent validity). The ROC analysis showed the CI had a high area under the curve (AUC = 0.719, predictive validity). CONCLUSIONS AND IMPLICATIONS: The CI demonstrates good validity properties with a strong correlation with the COMID and a high predictive value for coordination meeting. It is distinct from the other interRAI HC scales and has its place among them to support the clinical analysis of complex situations.

[Collaboration in home care: first interprofessional ambulatory proximity network]. / Collaboration dans les soins à domicile : un réseau interprofessionnel ambulatoire de proximité.

While interprofessionality is indispensable to respond to home care current issues, its implementation in the practice is a real challenge. The Genevan domiciliary model (reference by a nurse, targeted areas of interventions, etc.) needs to integrate all the resources of proximity. For this purpose, an interprofessional ambulatory and of proximity care network (RIAP) was created, aiming at strengthening the exchanges physicians/nurses about shared patients. RIAP benefits from an encouraging first assessment. Learnings from this experience are used to refine the modeling of this type of proximity network.

Alors que l'interprofessionnalité est indispensable pour répondre aux enjeux actuels du maintien à domicile, sa mise en œuvre dans la pratique représente un véritable défi. Le modèle domiciliaire genevois actuel (référence infirmière, zones d'interventions ciblées, etc.) nécessite d'intégrer toutes les ressources de proximité. Pour ce faire, un réseau de soins interprofessionnel ambulatoire de proximité (RIAP) a été créé, visant au renforcement de l'interprofessionnalité et résolument ancré dans la proximité des différents acteurs. Le RIAP repose notamment sur la consolidation des échanges médecins/infirmières autour de patients communs. Le premier bilan du RIAP est encourageant. Les apprentissages tirés de cette expérience permettent d'affiner la modélisation de ce type de réseau de proximité.

[Frailty and complexity indices derived from the interRAI HC Swiss]. / Indicateurs de fragilité et complexité dérivés de l'interRAI HC Suisse.

Frailty and complexity are concepts that are increasingly used by home care professionals. If the standardized global assessment as proposed by the Resident Assessment Instrument Home Care -(interRAI HC) includes aides for clinical analysis, it does not offer clinical index of frailty and complexity, which are however available in the literature. This article proposes an adaptation of the -algorithms from the fraXity study to the interRAI HCSuisse and -describes their implementation for the early detection of frailty and complexity in the routine assessment by the Geneva home care -institution (imad). These new indexes complete the panel of clinical scales and "alarms" already available and are accompanied by -recommendations for an integrated clinical practice.

La fragilité et la complexité sont des concepts de plus en plus ­mobilisés par les professionnels des soins à domicile. Si l'évaluation globale standardisée telle que proposée par le Resident Assessment Instrument Home Care (interRAI HC) inclut des aides à l'analyse clinique, elle n'offre pas d'indicateurs cliniques de fragilité et de complexité, pourtant disponibles dans la littérature. Cet article propose une adaptation des algorithmes issus de l'étude fraXity à l'interRAI HCSuisse et décrit leur implémentation pour le repérage précoce de la fragilité et la complexité dans l'évaluation de routine par l'Institution genevoise de maintien à domicile (imad). Ces nouveaux indicateurs complètent le panel d'échelles cliniques et d'« alarmes ¼ déjà disponibles et sont ­accompagnés de recommandations pour une pratique clinique intégrée.

Assessing multidimensional complexity in home care: congruencies and discrepancies between patients and nurses.

BACKGROUND: Person-centered care allows for the inclusion of the totality of a person's needs and preferences, beyond just the clinical or medical aspect. This approach requires the development of tools to allow for the integration of the patient in his/her healthcare. Based on a 30-item tool developed for nurses to evaluate the complexity of home care situations (COMID), this study proposed a version for the patients (i.e. COMID-P). Both instruments were used, independently by nurses and patients, to rate the complexity of individual situations, in order to compare ratings. METHODS: The COMID-P and the COMID were completed during the fraXity study at the patients' homes, independently by patients (aged 65 and over) and nurses. Item-level and scale-level analyses were performed using, Kappa and McNemar tests, and intra-class correlation (ICC). RESULTS: A total of 159 pairs of COMID and COMID-P ratings were retained for analyses. Results demonstrated a high degree of patient/nurse agreement for 12/30 items, a moderate agreement for 10/30 items, and a low degree of agreement for 7/30 items. The intra-class correlation between the COMID-P and the COMID was high (ICC= .826, 95%CI [.761-.873]). CONCLUSIONS: The results demonstrate that patients and nurses can assess complexity using tools that have comparable structural properties. They also reveal congruencies and discrepancies in scoring the components of complexity, highlighting the need of reaching consensus in designing care plans. Further work is needed to demonstrate the benefits of joint assessment in developing care plans that truly meet patients' needs. TRIAL REGISTRATION: The fraXity study was registered in ClinicalTrials.gov, NCT03883425 , on March 20, 2019.

Tooling nurses to assess complexity in routine home care practice: Derivation of a complexity index from the interRAI-HC.

AIM: Home care nurses often use the Resident Assessment Instrument-Home Care (interRAI-HC) to assess health needs. However, this tool does not assess complexity. This study proposes to derive a complexity index (CI) from the interRAI-HC using the operational definition of the dedicated COMID checklist (COmplexité Multidimensionnelle des prises en soins Infirmières à Domicile). DESIGN: Data were collected at the baseline assessment of the fraXity study (N = 231, aged ≥ 65), which relied on an observational longitudinal design. METHODS: Measures were the interRAI-HC, from which the CI binary variables were computed and the COMID, used as a reference. RESULTS: Twenty-six CI variables were computed from the interRAI-HC, and all but three correlations were significant. The correlation between the CI score and the COMID score was ρ = 0.730 (p < .001). CONCLUSIONS: The study demonstrates that complexity can be assessed directly from the interRAI-HC by deriving a CI.

Identification of diabetes self-management profiles in adults: A cluster analysis using selected self-reported outcomes.

The present study describes adult diabetes self-management (DSM) profiles using self-reported outcomes associated with the engagement in diabetes care activities and psychological adjustment to the disease. We used self-reported data from a community-based cohort of adults with diabetes (N = 316) and conducted a cluster analysis of selected self-reported DSM outcomes (i.e., DSM behaviors, self-efficacy and perceived empowerment, diabetes distress and quality of life). We tested whether clusters differed according to sociodemographic, clinical, and care delivery processes variables. Cluster analysis revealed four distinct DSM profiles that combined high/low levels of engagement in diabetes care activities and good/poor psychological adjustment to the disease. The profiles were differently associated with the variables of perceived financial insecurity, taking insulin treatment, having depression, and the congruence of the care received with the Chronic Care Model. The results could help health professionals gain a better understanding of the different realities facing people living with diabetes, identify patients at risk of poor outcomes related to their DSM, and lead to the development of profile-specific DSM interventions.

Interactional Effects Between Relational and Cognitive Reserves on Decline in Executive Functioning.

OBJECTIVES: The present study set out to investigate associations of cognitive reserve (as indicated by education) and relational reserve (as indicated by the family network size and indices of emotional support) to decline in executive functioning over 6 years as measured by changes in Trail Making Test (TMT) completion time in older adults and whether education and network size interacted with age and sex as covariates with respect to this longitudinal association. METHOD: We analyzed data from 897 participants tested on TMT parts A and B in two waves 6 years apart. The mean age in the first wave was 74.33 years. Participants reported information on their family networks and their level of education. RESULTS: Latent change score modeling testing for moderation effects revealed a significant interaction of network size in the first wave of data assessment with education. Specifically, for lower levels of cognitive reserve (-1 SD of education), the longitudinal association between relational reserve in the first wave and subsequent changes in executive functioning was not significant. In contrast, for higher levels of cognitive reserve (+1 SD of education), a higher relational reserve in the first wave significantly predicted a smaller subsequent increase in TMT completion time from the first to the second wave (i.e., a smaller decline in executive functioning). DISCUSSION: The present longitudinal study provides evidence for the interaction between cognitive and relational reserves. This confirms the hypothesis that reserves from different domains are intertwined and their combined effects contribute to less cognitive decline in old age.

Distinct effects of cognitive versus somatic anxiety on cognitive performance in old age: the role of working memory capacity.

Objective: The adverse effects of anxiety on cognition are widely recognized. According to Attentional Control Theory, worry (i.e. facet of cognitive anxiety) is the component that is responsible for these effects, and working memory capacity (WMC) plays an important role in regulating them. Despite the increasing importance of this problem with aging, little is known about how these mechanisms interact in old age. In this study, we explored the distinct contributions of the somatic and cognitive components of anxiety to neuropsychological performance, and the potential moderating role of WMC.Method: We administered cognitive tasks testing processing speed, cognitive flexibility and working memory to 605 older adults, who also underwent depression and test anxiety assessments (data from VLV study).Results: Multiple regression analyses showed that cognitive (but not somatic) aspects of anxiety affected cognitive flexibility. The effect of cognitive anxiety on processing speed was moderated by WMC: the anxiety-performance association was lower for participants with greater WMC.Conclusion: Results confirmed the specific role of worry in the anxiety-performance relationship in old age and supported the hypothesis that working memory resources regulates its deleterious effect on cognition. The absence of a moderation effect in the more costly switching task may reflect a limitation of resources with aging.

Motivation as a Mediator of the Relation Between Cognitive Reserve and Cognitive Performance.

OBJECTIVES: Interindividual differences in cognitive aging may be explained by differences in cognitive reserve (CR) that are built up across the life span. A plausible but underresearched mechanism for these differences is that CR helps compensating cognitive decline by enhancing motivation to cope with challenging cognitive situations. Theories of motivation on cognition suggest that perceived capacity and intrinsic motivation may be key mediators in this respect. METHOD: In 506 older adults, we assessed CR proxies (education, occupation, leisure activities), motivation (perceived capacity, intrinsic motivation), and a global measure of cognitive functioning. RESULTS: Perceived capacity, but not intrinsic motivation, significantly mediated the relation between CR and cognitive performance. DISCUSSION: Complementary with neurobiological and cognitive processes, our results suggest a more comprehensive view of the role of motivational aspects built up across the life span in determining differences in cognitive performance in old age.

[Analysis of the reliability of a multidimensional complexity scale instrument (COMID) for home care nurses]. / Analyse de la fidélité d'un instrument d'évaluation de la complexité multidimensionnelle (COMID) pour les infirmières à domicile.

Introduction : The increasingly frequent mention of complexity by different health care actors challenges the measurement of this construct. The COMID, a tool that helps home nurses to identify complex situations, provides a multidimensional and operational definition of complexity.Context : While an acceptability study showed that nurses took a keen interest in the COMID, its psychometric properties have not yet been examined.Objective : This article reports on two studies testing the reliability of the scale.Method : Study 1 focuses on 5,401 COMIDs completed by home care nurses in their usual practice. The internal consistency was estimated using Cronbach's alpha. Study 2 focuses on 38 COMIDs, completed by home care nurses (rater group 1) and specialized nurses (rater group 2). Inter-rater agreement was examined using an intraclass correlation coefficient (ICC).Results : The COMID has an acceptable internal consistency α = 0.797 and an excellent inter-rater agreement ICC = 0.839.Discussion : The metrological properties of the COMID will need to be complemented by an analysis of its validity. Conclusion : The COMID has good measurement accuracy and therefore has good potential for identifying complexity in nursing practice.

Cross-lagged relation of leisure activity participation to Trail Making Test performance 6 years later: Differential patterns in old age and very old age.

OBJECTIVE: We investigated cross-lagged relations between leisure activity participation and Trail Making Test (TMT) performance over 6 years and whether those reciprocal associations differed between individuals. METHOD: We analyzed data from 232 participants tested on performance in TMT Parts A and B as well as interviewed on leisure activity participation in 2 waves 6 years apart. Mean age in the Wave 1 was 73.42 years. Participants were also tested on vocabulary (Mill Hill scale) as a proxy indicator of crystallized intelligence and reported information on early and midlife cognitive reserve markers (education and occupation). Latent cross-lagged models were applied to investigate potential reciprocal activity-TMT relationships. RESULTS: The relation of leisure activity participation predicting TMT performance 6 years later was significantly larger than was the relation of TMT performance predicting later leisure activity participation. Statistically comparing different moderator groups revealed that this pattern was evident both in individuals with low education and in those with high education but, notably, emerged in only young-old adults (but not in old-old adults), in individuals with a low cognitive level of job in midlife (but not in those with a high cognitive level of job in midlife), and in individuals with high scores in vocabulary (but not in those with low scores in vocabulary). CONCLUSIONS: Late-life leisure activity participation may predict later cognitive status in terms of TMT performance, but individuals may markedly differ with respect to such effects. Implications for current cognitive reserve and neuropsychological aging research are discussed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Frailty in aging and its influence on perceived stress exposure and stress-related symptoms: evidence from the Swiss Vivre/Leben/Vivere study.

Frailty is a core concept in understanding vulnerability and adjustment to stress in older adults. Adopting the perspective provided by the transactional model of stress and coping (Lazarus and Folkman in Stress, appraisal, and coping, Springer, New York, 1984), the present study examined three aspects of frailty in older adults: (1) the link between frailty and perceived stress exposure (PSE); (2) the link between frailty and stress-related symptoms (SRS); and (3) the role of frailty in the link between PSE and SRS. Participants were 2711 adults aged between 64 and 101 years who were taking part in the Swiss Vivre/Leben/Vivere study. As well as assessing frailty, we measured PSE and SRS during the 4 weeks preceding the administration of the questionnaires, together with the covariates age, sex, educational attainment, language of the canton, and type of canton (urban vs. rural). Regression analyses revealed higher levels of PSE in frail older adults than in non-frail older adults. In addition, frail older adults reported more SRS than non-frail older adults. As expected, the association between PSE and SRS differed as a function of the frailty status: The positive relation between PSE and SRS being stronger for frail older adults than for non-frail older adults. These results suggest that frailty is related to perceived discrepancy between resources and demands, and to ability to cope with PSE. Our findings have implications for interventions to help frail older adults manage stress.

The role of cognitive reserve accumulated in midlife for the relation between chronic diseases and cognitive decline in old age: A longitudinal follow-up across six years.

OBJECTIVES: The present study set out to investigate relations of the number of chronic diseases (as a global indicator of individuals' multimorbidity) to cognitive status and cognitive decline over six years as measured by changes in Trail Making Test (TMT) completion time in old adults and whether those relations differed by key life course markers of cognitive reserve (education, occupation, and cognitively stimulating leisure activities). METHOD: We analyzed data from 897 participants tested on TMT parts A and B in two waves six years apart. Mean age in the first wave was 74.33 years. Participants reported information on chronic diseases, education, occupation, and cognitively stimulating leisure activities. RESULTS: Latent change score modeling testing for moderation effects revealed that a larger number of chronic diseases significantly predicted stronger increase in TMT completion time (i.e., steeper cognitive performance decline). Notably, the detrimental relation of the number of chronic diseases to stronger increase in TMT completion time (i.e., cognitive performance decline) was significantly stronger in individuals with less engagement in cognitively stimulating leisure activities in midlife. DISCUSSION: Present data suggest that disease-related cognitive decline may be steeper in individuals who have accumulated less cognitive reserve in midlife. However, greater midlife activity engagement seemed to be associated with steeper cognitive decline in any case. Implications for current cognitive reserve and neuropsychological aging research are discussed.

Influence of a screening navigation program on social inequalities in health beliefs about colorectal cancer screening.

The aim of the study was to test whether a screening navigation program leads to more favorable health beliefs and decreases social inequalities in them. The selected 261 noncompliant participants in a screening navigation versus a usual screening program arm had to respond to health belief measures inspired by the Protection Motivation Theory. Regression analyses showed that social inequalities in perceived efficacy of screening, favorable attitude, and perceived facility were reduced in the screening navigation compared to the usual screening program. These results highlight the importance of health beliefs to understand the mechanism of screening navigation programs in reducing social inequalities.

Determinants of patient delay in doctor consultation in head and neck cancers (Protocol DEREDIA).

INTRODUCTION: Reducing the time between the onset of the first symptoms of cancer and the first consultation with a doctor (patient delay) is essential to improve the vital prognosis and quality of life of patients. Longer patient delay is linked to the already known sociodemographic, socioeconomic, socioeducational, sociocultural and socioprofessional factors. However, recent data suggest that some sociocognitive and emotional determinants may explain patient delay from a complementary point of view. The main objective of this study is to assess whether, in head and neck cancer, patient delay is linked to these sociocognitive and emotional factors, in addition to previously known factors. METHODS AND ANALYSIS: We intend to include in this study 400 patients with a not yet treated head and neck cancer diagnosed in one of six health centres in the North of France region. The main evaluation criterion is 'patient delay'. Sociocognitive, emotional, medical, sociodemographic, socioeconomic, educational, professional and geographic factors will be assessed by means of (1) a case report form, (2) a questionnaire completed by the clinical research associate together with the patient, (3) a questionnaire completed by the patient and (4) a recorded semidirective interview of the patient by a psychologist (for 80 patients only). The collected data will be analysed to underline the differences between patients who consulted a doctor earlier versus those who consulted later. ETHICS: The study has obtained all the relevant authorisations for the protection of patients enrolled in clinical trials (CCTIRS, CCP, CNIL), does not involve products mentioned in article L.5311-1 of the French Code of Public Health, and does not imply any changes in the medical care received by the patients. The study began in October 2012 and will end in June 2015. TRIAL REGISTRATION: ID-RCB 2012-A00005-38.

Evaluating short-term and working memory in older adults: French normative data.

Short-term and working memory (WM) capacities are subject to change with ageing, both in normal older adults and in patients with degenerative or non-degenerative neurological disease. Few normative data are available for comparisons of short-term and WM capacities in the verbal, spatial and visual domains. To provide researchers and clinicians with a set of standardised tasks that assess short-term and WM using verbal and visuospatial materials, and to present normative data for that set of tasks. The present study compiled normative French data for three short-term memory tasks (verbal, visual and spatial simple span tasks) and two WM tasks (verbal and spatial complex span tasks) obtained from 445 healthy older adults aged between 55 and 85 years. Our data reveal main effects of age, education level and gender on older adults' short-term and WM performances. Equation-based normalisation can therefore be used to take these factors into account. The results provide a set of cut-off scores for five standardised tasks that can be used to determine the presence of short-term or WM impairment in older adults.
