Frailty screening comes of age

Factors Affecting Adherence, Intake, and Perceived Palatability of Oral Nutritional Supplements: A Literature Review

Oral nutritional supplements (ONS) are a clinically effective and relatively inexpensive way to supplement the diet of patients with, or at risk of, undernutrition. Good adherence is a primary determinant of the effectiveness of ONS. However adherence can be problematic for those with the greatest clinical need, such as undernourished older adults. This review aimed to appraise the available literature for the factors (contextual, personal and product related) affecting patient adherence and perceived palatability of ONS, identify areas requiring improvement and uncover gaps in the evidence to guide the focus of future research. Contextual factors identified were healthcare staff and the timing of administration. Personal factors included sensory changes and motivation which alter experience of and desire to consume ONS. The product's sensory characteristics determined palatability and intake, but undesirable attributes, such as off-flavours, can stem from nutritional ingredients. The contribution made by aroma to older adults' experience of ONS was a comparatively under-researched area. Further research should address this evidence gap to optimise the flavour, aroma profile and palatability for undernourished older consumers, thereby optimising intake. A combined multidisciplinary effort involving strategic expansion of research, industry development and clinical practice should simultaneously address the factors identified, to provide the best approach to improve adherence.

Screening for intrinsic capacity impairments as markers of increased risk of frailty and disability in the context of integrated care for older people: Secondary analysis of MAPT

AIM

This longitudinal secondary analysis of the Multidomain Alzheimer Preventive Trial (MAPT) aimed to test whether the Integrated Care for Older People (ICOPE) Step 1 screening tool is able to identify people at risk of developing frailty and disability in basic (ADL) and instrumental (IADL) activities of daily living among community-dwelling older adults.

PARTICIPANTS AND SETTING

Seven hundred and fifty-nine (n = 759) non-demented participants of the MAPT aged 70-89 years were assessed in memory clinics in France between 2008 and 2013.

METHODS

We measured six intrinsic capacity (IC) impairments, adapted from the ICOPE screening tool. We used Cox models to estimate the adjusted hazard ratios of incident frailty and IADL/ADL disability. Incident frailty was defined by Fried's phenotype, and incident disability was measured according to Lawton and Katz for IADLs and ADLs.

RESULTS

Limited mobility (HR= 2.97, 95%CI= 1.85-4.76), depressive symptoms (HR= 2.07, 95%CI= 1.03-4.19), and visual impairment (HR= 1.70, 95%CI 1.01-2.86) were associated with a higher incidence of frailty over 5 years. Each additional IC condition demonstrated a positive association with a higher risk of incident frailty, IADL, ADL disability, with risk increased by 47%, 27%, and 23% over 5 years, respectively.

CONCLUSION

Screening for IC impairments identifies older adults at higher risk of incident frailty and incident IADL/ADL disability. It is relevant to screen for these impairments together because the risk of frailty and disability increases with each additional one. ClinicalTrials.gov identifier: NCT00672685.

Neurocognitive Disorders: Importance of Early/Timely Detection in Daily Clinical Practice

Neurocognitive disorders create important challenges for patients, their families, and clinicians who provide their health care. Early/timely detection in daily clinical practice allows for diagnosis and adequate treatment, psychosocial support, education, and engagement in shared decision-making related to health care, life planning, involvement in research, and financial matters. However, neurocognitive disorders, when present, are not detected or not diagnosed and not documented, in more than half of patients seen by primary care physicians. The aim of this paper is to highlight the strategies and the perspectives to improve the early/timely detection of neurocognitive disorders in daily clinical practice.

Physical Frailty and Risk of Needing Long-Term Care in Community-Dwelling Older Adults: a 6-Year Prospective Study in Japan

OBJECTIVE

To examine the association between physical frailty and risk of needing long-term care, and compare the predictive value and clinical usefulness of a simple frailty scale (FRAIL) with that of the original Cardiovascular Health Study (CHS) criteria.

DESIGN AND SETTING

A 6-year prospective cohort study of community-dwelling older adults in a west Japanese suburban town.

PARTICIPANTS

1,554 older adults aged 65 years and over who were initially free of long-term care needs at baseline.

MEASUREMENTS

Physical frailty was defined by the CHS criteria and the FRAIL scale. The onset of needing long-term care was ascertained using national records of certification of long-term care needs. Cox proportional hazard models were used to estimate the association between physical frailty and risk of needing long-term care. Decision curve analysis was performed to compare the clinical usefulness of the two physical frailty criteria.

RESULTS

During a median follow-up of 5.8 years, 244 were ascertained as needing long-term care. Baseline physical frailty was significantly associated with elevated risk of needing long-term care, with a multivariable-adjusted hazard ratio (HR) of 2.00 (95% confidence interval [CI], 1.32-3.02) for being frail and 1.50 (95% CI, 1.10-2.03) for being pre-frail as defined by the CHS criteria, compared with being robust (p for trend = 0.001). Similar results were found for physical frailty defined by the FRAIL scale, with a multivariable-adjusted HR (95% CIs) of 2.11 (1.25-3.56) for being frail and 1.73 (1.28-2.35) for being pre-frail vs. being robust (p for trend < 0.001). The two physical frailty criteria had similar net benefits in identifying individuals at high risk for needing long-term care.

CONCLUSIONS

Physical frailty is significantly associated with an increased risk of needing long-term care in community-dwelling older adults in Japan. Compared with the original CHS criteria, the simple FRAIL scale has comparable predictive value and clinical usefulness for identifying individuals at risk for needing long-term care.

German translation, cross-cultural adaptation and diagnostic test accuracy of three frailty screening tools : PRISMA-7, FRAIL scale and Groningen Frailty Indicator

BACKGROUND

Routine screening for frailty could be used to timely identify older people with increased vulnerability und corresponding medical needs.

OBJECTIVE

The aim of this study was the translation and cross-cultural adaptation of the PRISMA-7 questionnaire, the FRAIL scale and the Groningen Frailty Indicator (GFI) into the German language as well as a preliminary analysis of the diagnostic test accuracy of these instruments used to screen for frailty.

METHODS

A diagnostic cross-sectional study was performed. The instrument translation into German followed a standardized process. Prefinal versions were clinically tested on older adults who gave structured in-depth feedback on the scales in order to compile a final revision of the German language scale versions. For the analysis of diagnostic test accuracy (criterion validity), PRISMA-7, FRAIL scale and GFI were considered the index tests. Two reference tests were applied to assess frailty, either based on Fried's model of a Physical Frailty Phenotype or on the model of deficit accumulation, expressed in a Frailty Index.

RESULTS

Prefinal versions of the German translations of each instrument were produced and completed by 52 older participants (mean age: 73 ± 6 years). Some minor issues concerning comprehensibility and semantics of the scales were identified and resolved. Using the Physical Frailty Phenotype (frailty prevalence: 4%) criteria as a reference standard, the accuracy of the instruments was excellent (area under the curve AUC >0.90). Taking the Frailty Index (frailty prevalence: 23%) as the reference standard, the accuracy was good (AUC between 0.73 and 0.88).

CONCLUSION

German language versions of PRISMA-7, FRAIL scale and GFI have been established and preliminary results indicate sufficient diagnostic test accuracy that needs to be further established.

A Frailty Index from Next-of-Kin Data: A Cross-Sectional Analysis from the Mexican Health and Aging Study

Objectives. To construct a frailty index from next-of-kin information of the last year of life of community-dwelling 50 years old or older adults and test its association with health services utilization. Methods. Cross-sectional analysis from next-of-kin data available from the last wave of the Mexican Health and Aging Study (MHAS). Measurements. Along with descriptive statistics, the frailty index (FI) was tested in regression models to assess its association with adverse outcomes previous to death: number of hospitalized days in the previous year and number of visits to a physician in the previous year, in unadjusted and adjusted models. Results. From a total of 2,649 individuals the mean of age was 74.8 (±11.4) and 56.3% (n = 1,183) were women. The mean of the FI was of 0.279 (±SD 0.131, R = 0.0–0.738) and distribution was biased to the right. There was a significant association (p < 0.001) between the FI and number of hospitalized days (β = 45.7, 95% CI 36.1–55.4, p < 0.001) and for the number of visits to a physician (β = 25.93, 95% CI 19.27–32.6, p < 0.001) both models adjusted for age and sex. Conclusion. The FI constructed with next-of-kin data showed similar characteristics to similar indexes of older adults. It was independently associated with health care use.

Welcome to the ICD-10 code for sarcopenia

The new ICD-10-CM (M62.84) code for sarcopenia represents a major step forward in recognizing sarcopenia as a disease. This should lead to an increase in availability of diagnostic tools and the enthusiasm for pharmacological companies to develop drugs for sarcopenia.

Does Frailty Predict Health Care Utilization in Community-Living Older Romanians?

Background. The predictive value of frailty assessment is still debated. We analyzed the predictive value of frailty of independent living elderly. The outcomes variables were visits to the general practitioner, hospital admission, and occurrence of new health problems. Methods. A one-year follow-up study was executed among 215 community-living old Romanians. General practitioners reported the outcome variables of patients, whose frailty was assessed one year before, using the Groningen Frailty Indicator. The predictive validity is analyzed by descriptive and regression analysis. Results. Three-quarters of all participants visited their general practitioner three times more last year and one-third were at least once admitted to a hospital. Patients who scored frail one year before were more often admitted to a hospital. Visits to the general practitioner and occurrence of new health problems were not statistically significant related to frailty scores. The frailty items polypharmacy, social support, and activities in daily living were associated with adverse outcomes. Conclusions. The predictive value of frailty instruments as the Groningen Frailty Indicator is still limited. More research is needed to predict health outcomes, health care utilization, and quality of life of frailty self-assessment instruments. Validation research on frailty in different "environments" is recommended to answer the question to what extent contextual characteristics influence the predictive value.

Frailty still matters to health and survival in centenarians: the case of China

Background

Frailty indicates accumulated vulnerability of adverse health outcomes in later life. Its robustness in predicting dependent living, falls, comorbidity, disability, health change, mortality, and health care utilization at older ages is well-documented. However, almost no studies have ever attempted to examine its robustness in centenarians, mainly due to data unavailability. This study examines prevalence of frailty in centenarians and its predictive powers on subsequent mortality and health conditions.

Methods

We use a sample of 4434 centenarians from the 2002, 2005, 2008, and 2011 waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS), with elders in three younger age groups 65–79, 80–89, and 90–99 as comparisons. Frailty is measured by a cumulative deficit index (DI) that is constructed from 39 variables covering physical and cognitive function, disease conditions, psychological well-being, and other health dimensions. Survival analysis is conducted to examine how frailty is associated with subsequent mortality at an average follow-up length of 3.7 years (2.6 years for deceased persons died in 2002–2011 and 7.6 years for survived persons at the 2011 wave). Logistic regressions are applied to examine how frailty is associated with subsequent physical and cognitive functions, disease conditions, and self-rated health with an average follow-up length of 3.0 years.

Results

The study reveals that centenarians are frailer than younger elders. The DI scores increase from less than 0.1 at ages 65–79 to over 0.30 in centenarians. Women are frailer than men at all ages. However, there is a great variation in frailty among all age groups. We also find that each additional increase of 0.01 score of the DI is associated with 1.6 % higher mortality risk (95 % CI: 1.014–1.018) in female centenarians and 1.4 % higher mortality risk (95 % CI: 1.010–1.018) in male centenarians, although these associations are weaker than those in other three younger age groups.

Conclusions

Frailty still plays an important role in determining subsequent health outcomes and mortality in centenarians.

Dehydration, Hypernatremia, and Hyponatremia

Disturbances of serum sodium are one of the most common findings in older persons. They are also a major cause of hospital admissions and delirium and are associated with frailty, falls, and hip fractures. Both hypernatremia and hyponatremia are potentially preventable. Treatment involves treating the underlying cause and restoring sodium and volume status to normal. The arginine vasopressin antagonists, vaptans, have increased the therapeutic armamentarium available to physicians.

Sarcopenia: the new definitions

PURPOSE OF REVIEW

To highlight the new international definitions of sarcopenia.

RECENT FINDINGS

New international definitions of sarcopenia have been evaluated and shown to be predictive of poor outcomes in older persons.

SUMMARY

There is now international agreement that the definition for sarcopenia should include not only muscle mass, but also some measure of muscle function, such as walking speed or distance or grip strength.

Exposure to atropinic drugs and frailty status

BACKGROUND

Atropinic drugs can increase the risk of falls, cognitive impairment, and mortality in older patients; however, whether exposure to atropinic drugs is associated with frailty status remains unknown. Our aim was to assess the association between frailty status and exposure to atropinic drugs in a geriatric day hospital population.

METHODS

We carried out a cross-sectional study that included all the patients consulting for the first time at the Geriatric Frailty Clinic for Assessment of Frailty and Prevention of Disability in Toulouse, France, from January 2013 to October 2013. Frailty was defined by 3 or more of Fried et al's criteria. Atropinic drugs were those with clinical antimuscarinic effect from the Anticholinergic Drug Scale (excluding drugs weighted 1 point and not listed by Durán et al) and from Laroche et al list (to include drugs marketed in France not present in the Anticholinergic Drug Scale). To explore a dose-effect relationship, we calculated the atropinic burden using the Anticholinergic Drug Scale weights. We performed logistic regression models adjusted for age, gender, comorbidities, being community dwelling or not, cognitive status, educational level, and polypharmacy (≥6 drugs).

RESULTS

We included 437 patients (227 frail and 210 robust or prefrail). Exposure to at least one atropinic drug was associated with frailty (odds ratio 1.97, 95% confidence interval 1.10-3.53, P = .02). Due to a statistically significant interaction between age and atropinic burden, a dose-effect relationship for atropinic burden was explored in patients younger than 85 years, showing a significant association between atropinic burden score and frailty (P = .01). The Odds ratio for an atropinic burden greater than or equal to 3 versus 0 was 3.84, 95% confidence interval 1.43-10.34 (P < .01).

CONCLUSIONS

In a geriatric day hospital, population frailty is associated with a high atropinic burden.
