Quadriceps muscle strength is a discriminant predictor of dependence in daily activities in nursing home residents.

ABSTRACT: OBJECTIVE:This study aimed to explore the relationship between dependence in Activities of Daily Living and muscle strength, muscle morphology and physical function in older nursing home residents, taking possible confounders into consideration. METHODS:A total of 30 nursing home residents (age, 85.6±7.1 years) were included in this observational cross-sectional study. Performance of basic Activities of Daily Living (ADL) was assessed with the Resident Assessment Instrument and categorized as either independent or dependent. Isometric grip, quadriceps and elbow-flexor strength were determined by hand-dynamometry, muscle thickness and echo intensity by B-mode ultrasonography, a sit-to-stand task by using a stop watch and physical activity by the German-Physical-Activity Questionnaire. Degree of frailty was evaluated according to Fried's frailty criteria, whereas cognition, depression, incontinence, pain and falls were part of the Resident Assessment Instrument. RESULTS:Dependence in Activities of Daily Living was negatively correlated with physical activity (rs = -0.44, p = .015), handgrip (rs = -0.38, p = .038), elbow-flexor (rs = -0.42, p = .032) and quadriceps strength (rs = -0.67, p < .001), analysed by Spearman's correlation. Chronic diseases (rs = -0.41, p = .027) and incontinence (rs = -0.39, p = .037) were positively correlated with ADL while the other variables were not related. Only quadriceps strength remained significant with logistic regression (Wald(1) = 4.7, p = .03), when chronic diseases, quadriceps and handgrip strength were considered (R2 .79). 11 kg was the best fitting value in this sample to predict performance in Activities of Daily Living, evaluated with Receiver-Operating Characteristic analysis, with a sensitivity of 100% and a specificity of 79%. CONCLUSION AND IMPLICATION:Quadriceps strength had a positive independent relationship with performance in ADL in the nursing home residents studied. Although a large prospective study is needed to verify the results, maintaining quadriceps strength above 11 kg may be helpful in retaining independence in this cohort.

Project description:BackgroundInterdependencies of health, fitness, cognition, and emotion can promote or inhibit mobility. This study aimed to analyse pathways and interactions between individual subjective and objective physical performance, cognition, and emotions with activities of daily living (ADLs) as mobility indicators in multimorbid nursing home residents.MethodsThe study included n = 448 (77.1% females, age = 84.1 ± 7.8 years) nursing home residents. To describe the participant's demographics, frailty, number of falls, and participating institutions' socioeconomic status (SES) were assessed. ADLs were measured with the Barthel Index (BI; dependent variable). Independent variables included objective physical performance, subjective physical performance, cognition, and emotions. A structural equation model (SEM) with maximum likelihood estimation was conducted with AMOS. Direct and indirect effects were estimated using standardized coefficients (significance level of 0.05).ResultsIndices showed (Chi2(148) = 217, PCMIN/DF = 1.47; p < .001; Comparative Fit Index = .940; Tucker Lewes Index = .902, RMSEA = .033) that the model fitted the data adequately. While there was no direct association between emotions, subjective physical performance, and ADLs, objective physical performance and cognition predicted higher ADLs (p < .01). Emotions had a strong relationship with subjective physical performance, and cognition had a moderate relationship with objective physical performance.Discussion and conclusionObjective performance and cognition predicted higher functional status, as expressed by higher BI scores. ADLs, such as mobility, dressing, or handling tasks, require motor and cognitive performance. Subjective performance is an important predictor of ADLs and is only partly explained by objective performance, but to a large extent also by emotions. Therefore, future interventions for nursing home residents should take a holistic approach that focuses not only on promoting objective physical and cognitive performance but also on emotions and perceived physical performance.Trial registrationTrial registration number: DRKS00014957.

Project description:OBJECTIVE:Severe sepsis survivors frequently experience cognitive and physical functional impairment. The degree of impairment and its association with mortality is understudied, particularly among those discharged to a skilled nursing facility. Our objective was to quantify the cognitive and physical impairment among severe sepsis survivors discharged to a skilled nursing facility and to investigate the relationship between impairment and long-term mortality. DESIGN:Retrospective cohort study. SETTING:United States. SUBJECTS:Random 5% sample of Medicare patients discharged following severe sepsis hospitalization, 2005-2009 (n = 135,370). MEASUREMENT AND MAIN RESULTS:Medicare data were linked with the Minimum Data Set; Minimum Data Set-Cognition Scale was used to assess cognitive function, and the Minimum Data Set activities of daily living hierarchical scale was used to assess functional dependence. Associations were evaluated using multivariable logistic regression, Kaplan-Meier curves, and Cox proportional hazards regression. Of 66,540 beneficiaries admitted to a skilled nursing facility following severe sepsis, 34% had severe or very severe cognitive impairment, and 72.5% had maximal, dependence, or total dependence in activities of daily living. Median survival was 19.4 months for those discharged to a skilled nursing facility without having been in a skilled nursing facility in the preceding 1 year and 10.4 months for those discharged to a skilled nursing facility who had spent time in a skilled nursing facility in the prior year. The adjusted hazard ratio for death was 3.1 for those with very severe cognitive impairment relative to those who were cognitively intact (95% CI, 2.9-3.2; p < 0.001) and 4.3 for those with "total dependence" in activities of daily livings relative to those who were independent (95% CI, 3.8-5.0; p < 0.001). CONCLUSIONS:Discharge to a skilled nursing facility following severe sepsis hospitalization among Medicare beneficiaries was associated with shorter survival, and cognitive impairment and activities of daily living dependence were each strongly associated with shortened survival. These findings can inform decision-making by patients and physicians and underscores high palliative care needs among sepsis survivors discharged to skilled nursing facility.

Project description:AIMS AND OBJECTIVES:To explore nursing home residents' perspectives on their relationships with other residents, family members and staff. BACKGROUND:The cultivation of social relationships is central to promoting well-being in nursing homes, as these relationships allow residents, family members and staff to be valued as unique persons and empowered as partners in care. Few studies have examined how nursing home residents perceive the relationships in their social networks, both within and beyond the facility. DESIGN:Qualitative secondary analysis. METHODS:We analysed individual and group interviews obtained during "stakeholder engagement sessions" with cognitively intact residents (N = 11 sessions; N = 13 participants) from two nursing homes in North Carolina. The interviews were conducted as part of a larger study on person-directed care planning. We integrated thematic and narrative analytic approaches to guide the analysis of interview data, using a three-cycle coding approach. The COREQ checklist was followed. RESULTS:Four broad themes emerged from this analysis: (a) peer relationships foster a sense of belonging, purpose, achievement and significance; (b) residents' relationships with family members support a sense of belonging, continuity and significance; (c) mutual respect and reciprocity between residents and nursing home staff promote a sense of belonging and significance; and (d) organisational factors pose barriers to forging meaningful relationships. Each type of relationship-peer, family and staff-made distinctive contributions residents' psychosocial well-being. CONCLUSION:Recognising the diverse roles of different actors from residents' social networks raises questions for future research to optimise the distinctive contributions of network members that promote residents' psychosocial well-being. RELEVANCE TO CLINICAL PRACTICE:This study highlights the need for nursing home staff to understand how residents' social relationships influence residents' psychosocial outcomes. Staff training programmes are needed to support residents' rights and to dispel inaccurate interpretations of regulations that threaten sustained meaningful relationships.
