Project description:ContextVitamin D deficiency is a global public health issue, particularly in nursing home residents.ObjectiveThis review critically summarizes the prevalence of vitamin D deficiency in nursing home residents worldwide. In addition, it outlines the effect of vitamin D intervention, alone or in combination with other nutrients or therapies, on improving vitamin D status and associated health outcomes in nursing home residents.Data sources, extraction, and analysisSearches were conducted of electronic databases for articles published from 2010 to May 2021. After screening of the 366 papers initially identified, 58 articles were included.ConclusionsA paucity of observational studies in nursing homes suggests a high prevalence of vitamin D deficiency ranging from 8% [25(OH)D <25 nmol/L], up to 94% [25(OH)D <50 nmol/L] in some cohorts where supplement use was low. Reported factors associated with deficiency and suboptimal vitamin D status include lack of sunlight exposure, poor dietary intake of vitamin D, limited vitamin D food fortification, frailty, poor renal function, and low use of vitamin D supplements. Residents who are severely deficient, deficient, or insufficient in vitamin D require remedial vitamin D supplementation prior to maintenance supplementation at doses >800 IU/day. High-dose vitamin D supplementation may reduce respiratory illness; however, supportive data are limited. Oral nutritional supplements, in combination with exercise, may benefit physical function and performance, whereas supplementation with vitamin D- and calcium-fortified foods has been associated with improved quality of life and reduced bone resorption. Globally, vitamin D deficiency is highly prevalent in nursing home residents. There is an urgent need for standardized dietary and supplementation guidelines to prevent deficiency in this vulnerable group.

Project description:To determine functional status and mortality rates after colon cancer surgery in older nursing home residents.Retrospective cohort study.Nursing homes in the United States.Six thousand eight hundred twenty-two nursing home residents aged 65 and older who underwent surgery for colon cancer in the United States between 1999 and 2005.Changes in functional status were assessed before and after surgery using the Minimum Data Set Activity of Daily Living (MDS-ADL) summary scale, a 28-point scale in which score increases as functional dependence increases. Regression techniques were used to identify patient characteristics associated with mortality and functional decline 1 year after surgery.On average, residents who underwent colectomy had a 3.9-point worsening in MDS-ADL score at 1 year. One year after surgery, rates of mortality and sustained functional decline were 53% and 24%, respectively. In multivariate analysis, older age (? 80 vs 65-69, adjusted relative risk (ARR) = 1.53, 95% confidence interval (CI) = 1.15-2.04, P < .001), readmission after surgical hospitalization (ARR = 1.15, 95% CI = 1.03-1.29, P = .02), surgical complications (ARR = 1.11, 95% CI = 1.02-1.21, P = .01), and functional decline before surgery (ARR = 1.21, 95% CI = 1.11-1.32, P < .001) were associated with functional decline at 1 year.Mortality and sustained functional decline are common after colon cancer surgery in nursing home residents. Initiatives aimed at improving surgical outcomes are needed in this vulnerable population.

Project description:ObjectiveTo determine if immune phenotypes associated with immunosenescence predict risk of respiratory viral infection in elderly nursing home residents.MethodsResidents ? 65 years from 32 nursing homes in 4 Canadian cities were enrolled in Fall 2009, 2010 and 2011, and followed for one influenza season. Following influenza vaccination, peripheral blood mononuclear cells (PBMCs) were obtained and analysed by flow cytometry for T-regs, CD4+ and CD8+ T-cell subsets (CCR7+CD45RA+, CCR7-CD45RA+ and CD28-CD57+) and CMV-reactive CD4+ and CD8+ T-cells. Nasopharyngeal swabs were obtained and tested for viruses in symptomatic residents. A Cox proportional hazards model adjusted for age, sex and frailty, determined the relationship between immune phenotypes and time to viral infection.Results1072 residents were enrolled; median age 86 years and 72% female. 269 swabs were obtained, 87 were positive for virus: influenza (24%), RSV (14%), coronavirus (32%), rhinovirus (17%), human metapneumovirus (9%) and parainfluenza (5%). In multivariable analysis, high T-reg% (HR 0.41, 95% CI 0.20-0.81) and high CMV-reactive CD4+ T-cell% (HR 1.69, 95% CI 1.03-2.78) were predictive of respiratory viral infection.ConclusionsIn elderly nursing home residents, high CMV-reactive CD4+ T-cells were associated with an increased risk and high T-regs were associated with a reduced risk of respiratory viral infection.

Project description:Subsyndromal delirium (SSD) complicates diagnosis of delirium and dementia, although there is little research comparing their symptom profiles.Cross-sectional study of 400 elderly patients' admission to a general hospital or nursing home diagnosed with delirium, SSD, dementia, or no-delirium/no-dementia (NDND). Symptom profiles were assessed using the Delirium Rating Scale-Revised-98 (DRS-R98).Twenty percent patients had delirium, 19.3% had SSD, 29.8% had dementia-only, and 31% had NDND. Eighty-one percent of subsyndromal and 76% of delirium groups had comorbid dementia. DRS-R98 scores showed ascending severity from NDND < dementia-only < SSD < delirium. DRS-R98 scores for items evaluating the three core symptom domains (cognitive, higher-order thinking, and circadian) distinguished SSD from delirium and both from nondelirium groups. DRS-R98 profiles were essentially the same in delirium and SSD subgroups with or without dementia, although total scale scores were generally higher when in comorbid subgroups.SSD shared characteristic core domain symptoms with delirium, which distinguished each from nondelirium groups, although severity was intermediate in the subsyndromal group. Delirium core symptoms overshadowed the dementia phenotype when comorbid. Milder disturbances of delirium core domain symptoms are highly suggestive of SSD.

Project description:BackgroundPhysical activity (PA) is low among elderly residents in nursing homes in China. We aimed to determine the factors that influence PA among elderly nursing home residents and their direct or indirect effects on PA levels.MethodsThe PA levels of the participants were measured using the International Physical Activity Questionnaire, and their health beliefs were assessed using a self-developed 18-item questionnaire titled the 'Health Beliefs of Nursing Home Residents Regarding Physical Activity' in accordance with Health Belief Model (HBM) constructs. The correlations between HBM constructs and PA levels were analyzed and a regression-based path analysis was conducted to examine the relationships between HBM constructs and PA levels.ResultsA total of 180 residents with a mean age of 82.5 years (standard deviation = 5.76) were recruited. Linear regression analysis revealed that self-efficacy (p < 0.001), perceived severity (p < 0.01), and cues to action (p < 0.01) were associated with the level of PA among nursing home residents. In the conceptual path model, self-efficacy, perceived severity, and cues to action had positive direct effects on the PA level, while perceived benefits and perceived barriers had indirect effects on the PA level.ConclusionThe residents' self-efficacy, perceived severity, and cues to action were found to be important factors that can affect the design and implementation of educational programs for PA. A better understanding of such associations may help healthcare providers design informed educational interventions to increase PA levels among nursing home residents.

Project description:In a national sample of Medicare nursing home residents with dementia treated with bisphosphonates, 20% had bisphosphonates deprescribed. Residents with clinical characteristics representing decreased likelihood for long-term benefit were more likely to have bisphosphonates deprescribed. Future studies are needed to evaluate outcomes of deprescribing bisphosphonates in this population.IntroductionTo determine incidence of deprescribing bisphosphonates among nursing home (NH) residents with dementia and identify factors associated with deprescribing.Methods2015-2016 Medicare claims, Part D prescriptions, Minimum Data Set (MDS) 3.0, and Nursing Home Compare for non-skilled NH residents aged 65 + with dementia and prescriptions for oral bisphosphonates overlapping the first 14 days of the stay. Our primary definition for deprescribing was a 90-day gap in medication supply; we also explored the reliability of different deprescribing definitions (30-, 90-, 180-day gaps). We estimated associations of NH, provider, and resident characteristics with deprescribing bisphosphonates using competing risks regression models.ResultsMost NH residents with dementia treated with bisphosphonates (n = 5312) were ≥ 80 years old (72%), white (81%), and female (90%); about half were dependent for transfers (50%) or mobility (45%). Using a 90-day gap in supply, the 180-day cumulative incidence of deprescribing bisphosphonates was 14.8%. This increased to 32.1% using a 30-day gap and decreased to 11.7% using a 180-day gap. Factors associated with increased likelihood for bisphosphonate deprescribing were age ≥ 90 years, newly admitted (vs. prevalent stay), dependent for mobility, swallowing difficulty, > 1 hospitalization in the prior year, CCRC facility, and nurse practitioner primary provider (vs. physician). Cancer and western geographic region were associated with reduced likelihood for deprescribing.ConclusionIn a national sample of NH residents with dementia, bisphosphonate deprescribing was uncommon, and associated with clinical characteristics signifying poor prognosis and decreased likelihood for long-term benefit. Future studies should evaluate clinical outcomes of deprescribing bisphosphonates in this population.

Project description:Little is known about the prognostic value of the strength, assistance walking, rise from a chair, climb stairs, and falls questionnaire (SARC-F) and SARC-F combined with calf circumference (SARC-CalF) among elderly nursing home residents.To compare the prognostic value of SARC-F and SARC-CalF for mortality in this population.We conducted a prospective study in four nursing homes in western China. Sarcopenia was estimated using SARC-F and SARC-CalF, respectively. Nutrition status, activities of daily living, and other covariates were evaluated. The survival status was collected via medical records and telephone interviews at the 12th month after the baseline investigation. We used multivariate Cox proportional-hazard models to calculate the hazard ratio (HR) and 95% confidence interval (CI) for 1-year all-cause mortality by SARC-F-defined sarcopenia and SARC-CalF-defined sarcopenia, separately.We included 329 participants (median age: 85 years). The prevalences of SARC-F-defined sarcopenia and SARC-CalF-defined sarcopenia were 39.8% and 46.8%, respectively. During the 1-year follow-up period, 73 participants (22.7%) died. The mortality was 29.0% and 18.3% in the participants with or without SARC-F-defined sarcopenia, respectively (P = .025). The mortality was 26.6% and 19.0% in the participants with or without SARC-CalF-defined sarcopenia, respectively (P = .105). After adjusted for the relevant confounders including malnutrition, SARC-F-defined sarcopenia was independently associated with an increased risk of 1-year mortality (adjusted HR: 2.08; 95% CI: 1.27-3.42). However, SARC-CalF-defined sarcopenia was not an independent predictor of 1-year mortality (adjusted HR: 1.54; 95% CI: 0.95-2.47).Sarcopenia is highly prevalent in Chinese elderly nursing home residents according to SARC-F or SARC-CalF. SARC-F-defined sarcopenia appears to be better for predicting the 1-year mortality of Chinese nursing home residents than SARC-CalF-defined sarcopenia.

Project description:BackgroundAge-related loss of muscle mass and function is common in older adults, and studies investigating if dietary proteins may protect and possibly build lean body mass are needed. We assessed the feasibility of conducting a nutritional intervention study in older nursing home residents to investigate the effects of fish protein supplementation on markers of glucose metabolism and inflammation.MethodsThis was a double-blind randomised controlled pilot study. Twenty-four nursing home residents, without major cognitive impairment, received a daily oral nutritional supplement containing 5.2 g of fish protein or placebo for 6 weeks. Anthropometric measurements were conducted at baseline. Participants were screened for nutritional risk using the Mini Nutritional Assessment and activities of daily living using the Barthel index and dietary intake was registered. Hand grip strength was measured and fasting blood samples collected at baseline and endpoint.ResultsCompliance was high and dropout was low, but participant recruitment was challenging. Serum concentrations of monocyte chemoattractant protein-1 decreased, and C-reactive protein increased in the intervention group compared to control, with no changes in markers of glucose metabolism between groups.ConclusionConducting a nutritional intervention using fish protein supplementation in older nursing home residents is feasible but should be conducted as a multi-centre study to account for the low recruitment rate observed in the present study. A full-scale study is needed to gain more knowledge on the potential effects of fish proteins on markers of glucose metabolism and inflammation in relation to the age-related loss of muscle mass and function.Trial registrationClinicalTrials.gov NCT03529344 18.05.2018 (retrospectively registered).

Project description:Chronic dehydration mainly occurs due to insufficient fluid intake over a lengthy period of time, and nursing home residents are thought to be at high risk for chronic dehydration. However, few studies have investigated chronic dehydration, and new diagnostic methods are needed. Therefore, in this study, we aimed to identify risk factors for chronic dehydration by measuring serum osmolality in nursing home residents and also to evaluate whether examining the inferior vena cava (IVC) and determining the IVC collapsibility index (IVC-CI) by ultrasound can be helpful in the diagnosis of chronic dehydration. A total of 108 Japanese nursing home residents aged ≥65 years were recruited. IVC measurement was performed using a portable handheld ultrasound device. Fifteen residents (16.9%) were classified as having chronic dehydration (serum osmolality ≥295 mOsm/kg). Multivariate logistic regression analysis showed that chronic dehydration was associated with dementia (odds ratio (OR), 6.290; 95% confidential interval (CI), 1.270-31.154) and higher BMI (OR, 1.471; 95% CI, 1.105-1.958) but not with IVC or IVC-CI. Cognitive function and body weight of residents should be considered when establishing a strategy for preventing chronic dehydration in nursing homes.
