Use of Functional Assessment to Define Therapeutic Goals and Treatment

The Complex Relationship Between Social and Functional Needs in Frail Older Adults

Background

There has been a growing interest in integrating social and function-focused care into health care settings. Little is known about what older adults perceive as the needs that impact their lives, and the resources to address patients' social and functional needs often exist outside of traditional health care settings.

Methods

Our objective was to understand frail older adults' and community organizations' perspectives on what social and functional needs impact older adults' health, the support they receive, and how organizations and health systems could partner to address these needs. We conducted semi-structured interviews with patients and community-based organizations. Patients were aged 65 years or older, frail (electronic frailty index greater than 0.21), and at an increased geographic risk of unmet social needs (Area Deprivation Index greater than or equal to the 75th percentile). Staff were from organizations that provided social and/or functional resources to older adults. We used an inductive content analysis approach and the constant comparative method to analyze the data and identify themes.

Results

We interviewed 23 patients and 28 staff from 22 distinct organizations. We found that social, financial, and functional needs were common and highly intertwined among older adults with frailty, but the support they received at home, from their health care providers, and from community organizations was highly varied.

Limitations

Our sample was limited to participants from one county, so the results may not be generalizable to other areas. We only inter-viewed organizations and patients with frailty.

Conclusions

Health systems and community organizations have distinct areas of expertise, and purposeful collaboration between them could be important in addressing the needs of frail older adults.

Investigating the association of anticholinergic burden with depression in older adults: a cross-sectional study

BACKGROUND

Although depression and anticholinergic drug use are common comorbidities that impair health status in later life, there are insufficient data on their relationship. This study aimed to investigate the relationship between depressive symptoms and anticholinergic use in older individuals.

METHODS

Community-dwelling older adults (≥65 years) admitted to the tertiary referral geriatric outpatient clinic were included. Participants were evaluated for depressive symptoms using the Geriatric Depression Scale (GDS) with a cut-off score of ≥6 for depression. Exposure to anticholinergic drugs was assessed using the anticholinergic cognitive burden (ACB) scale and three subgroups were created: ACB = 0, ACB = 1, and ACB ≥ 2. The relationship between these two parameters was assessed using multivariate logistic regression analysis considering other potential variables.

RESULTS

The study included 1232 participants (mean age 78.4 ± 7.2 years and 65.2% female) and the prevalence of depression was 24%. After adjusting for potential confounders, compared to ACB = 0, having ACB ≥ 2 was related to depression symptoms (odds ratio (OR): 1.56, 95% CI: 1.04-2.35, P = 0.034), whereas having ACB = 1 did not increase the risk (OR: 1.27, 95% CI: 0.88-1.83, P = 0.205).

CONCLUSION

Our findings indicate that special attention should be paid to drug therapy in preventing depression in older adults, as exposure to a high anticholinergic load is negatively associated with psychological status.

A Comprehensive Review on Managing Fracture Calcaneum by Surgical and Non-surgical Modalities

This comprehensive review delves into the multifaceted landscape of calcaneal fractures, thoroughly examining their aetiology, clinical presentation, and diverse management strategies. Encompassing surgical and non-surgical approaches, the review scrutinises critical aspects such as patient compliance, rehabilitation protocols, and long-term follow-up considerations. Surgical modalities, propelled by recent innovations like minimally invasive techniques and advanced fixation materials, are juxtaposed with non-surgical interventions, emphasising the pivotal role of patient education and adherence to optimise outcomes. The synthesis of critical findings underscores the need for individualised care and multidisciplinary collaboration in clinical practice. Moreover, the review outlines recommendations for healthcare practitioners and identifies promising areas for future research, including biomechanical studies and telerehabilitation. This comprehensive exploration aims to contribute to the ongoing evolution of calcaneal fracture management, ultimately enhancing patient care and outcomes in this complex orthopaedic realm.

Comparison between the General Assessment of Hospitalised Patient Tool and the Barthel Index: A Retrospective Study

Among hospitalised patients, functional decline and increased dependence on others are common health problems. Identifying critical needs is an important starting point to empower patients to improve their own health and behaviour. Once these needs are determined, the most relevant goals for addressing patients' needs and health potential can be established. This study aimed to test a model for profiling patients using the General Assessment of Hospitalised Patients (ASGO) compared to the Barthel Index (BI) as the gold standard. A retrospective approach was conducted by reviewing administrative data recorded between 2017 and 2020 at the University of Padova, Italy. Data from patients (a) older than 18 years, (b) admitted to a local hospital, and (c) with a stay of at least three days were included in the study. The ASGO and the BI were both used on patients' admission and discharge from the ward. Data were analysed using STATA software (v.16) (StataCorp. 2019. Stata Statistical Software: Release 16. College Station, TX: StataCorp LLC). The database used for the analysis consisted of 842 patient records, with more than 50% over 75 years of age and consisting mainly of men. The results of the ASGO and the BI were more correlated at discharge (rho = -0.79) than at admission (rho = -0.59). Furthermore, sensitivity and specificity, calculated with reference to the optimal cut-off point (Youden index), demonstrated the highest reliability of the test at discharge (sensitivity: 0.87; specificity: 0.78) compared to admission (sensitivity: 0.77; specificity: 0.72). This result was confirmed by the analysis of the ROC curve: The area under the curve was greater at discharge (89%) than at admission (82%). Analysis of the results obtained from assessments created with the ASGO demonstrates the applicability of this model in the context of hospital care and how well it can represent functional dependence. This study was not registered.

Comparison of Two Electronic Physical Performance Batteries by Measurement Time and Sarcopenia Classification

The Short Physical Performance Battery (SPPB) is a widely accepted test for measuring lower extremity function in older adults. However, there are concerns regarding the examination time required to conduct a complete SPPB consisting of three components (walking speed, chair rise, and standing balance tests) in clinical settings. We aimed to assess specific examination times for each component of the electronic Short Physical Performance Battery (eSPPB) and compare the ability of the original three-component examinations (eSPPB) and a faster, two-component examination without a balance test (electronic Quick Physical Performance Battery, eQPPB) to classify sarcopenia. The study was a retrospective, cross-sectional study which included 124 ambulatory outpatients who underwent physical performance examination at a geriatric clinic of a tertiary, academic hospital in Seoul, Korea, between December 2020 and March 2021. For eSPPB, we used a toolkit containing sensors and software (Dyphi, Daejeon, Korea) developed to measure standing balance, walking speed, and chair rise test results. Component-specific time stamps were used to log the raw data. Duration of balance examination, 5 times sit-to-stand test (5XSST), and walking speed examination were calculated. Sarcopenia was determined using the 2019 Asian Working Group for Sarcopenia (AWGS) guideline. The median age was 78 years (interquartile range, IQR: 73,82) and 77 subjects (62.1%) were female. The total mean eSPPB test time was 124.8 ± 29.0 s (balance test time 61.8 ± 12.3 s, 49.5%; gait speed test time 34.3 ± 11.9 s, 27.5%; and 5XSST time 28.7 ± 19.1 s, 23.0%). The total mean eQPPB test time was 63.0 ± 25.4 s. Based on the AWGS criteria, 34 (27.4%) patient’s results were consistent with sarcopenia. C-statistics for classifying sarcopenia were 0.83 for eSPPB and 0.85 for eQPPB (p = 0.264), while eQPPB took 49.5% less measurement time compared with eSPPB. Breakdowns of eSPPB test times were identified. Omitting balance tests may reduce test time without significantly affecting the classifying ability of eSPPB for sarcopenia.

Comparison of Human Interpretation and a Rule-Based Algorithm for Instrumented Sit-to-Stand Test

BACKGROUND

The five times sit-to-stand test (5STS) is one of the most commonly used tests to assess the physical performance of lower extremities. This study assessed the correlation between human interpretation (5STShuman) and a rule-based algorithm (5STSrule) using instrumented 5STS with two sensors.

METHODS

We analyzed clinical records of 148 patients who visited the geriatric outpatient clinic of Asan Medical Center between December 2020 and March 2021 and underwent physical performance assessment using the electronic Short Physical Performance Battery (eSPPB) protocol. For STS, time-weight and time-distance curves were constructed using a loadcell and light detection and ranging (LiDAR). We manually assessed the grids of these curves to calculate 5STShuman, while 5STSrule used an empirical rule-based algorithm.

RESULTS

In the study population, the mean 5STShuman and 5STSrule times, i.e., 12.2±0.4 and 11.4±0.4 seconds, respectively, did not differ significantly (p=0.232). Linear regression analysis showed that 5STShuman and 5STSrule were positively correlated (β=0.99, R2=0.99). The measures also did not differ (p=0.381) in classifying sarcopenia according to the Asian Working Group Society criteria, with C-indices of 0.826 for 5STShuman and 0.820 for 5STSrule.

CONCLUSION

An empirical rule-based algorithm correlated with human-interpreted 5STS and had comparable classification ability for sarcopenia.

Short Physical Performance Battery as a crosswalk between frailty phenotype and deficit-accumulation frailty index

BACKGROUND

Growing evidence supports clinical importance of evaluating frailty in older adults, with its strong outcome relevance. We aimed to assess whether the Short Physical Performance Battery (SPPB) correlates with frailty status according to phenotype and deficit accumulation models and can be used as a link between these models.

METHODS

We analyzed records of 1064 individuals from the Aging Study of Pyeongchang Rural Area, a population-based, prospective cohort from South Korea. Frailty was determined using the Cardiovascular Health Study (CHS) phenotype (phenotype model), 26- and 34-item frailty indice (deficit accumulation model). Associations of SPPB score and frailty with a composite outcome of mortality or long-term institutionalization were assessed. Crosswalks for SPPB, the CHS frailty phenotype and the frailty index were created.

RESULTS

The mean age of the study population was 76.0 years, and 583 (54.8%) were women. According to the CHS phenotype, 26- and 34-item frailty index, 242 (22.7%), 161 (15.1%) and 280 (26.3%) participants, respectively, had frailty. Sensitivities/specificities for classifying CHS phenotype, 26- and 34- item frailty indices were 0.93/0.55, 0.71/0.84 and 0.80/0.83 by SPPB cut points of ≤9, ≤6 and ≤7, respectively. C-index of SPPB score (0.78) showed a predictive ability for the composite outcome that was comparable to that of CHS frailty phenotype (0.79), 26- (0.78) and 34-item frailty index (0.79).

CONCLUSION

We could create a crosswalk linking frailty phenotype and frailty index from correlations between SPPB and frailty models. This result may facilitate clinical adoption of the frailty concept in broader spectrum of older adults.

Functional Voice Assessment and Therapy Methods Supported by Telepractice, VoiceEvalU8, and Estill Voice Training

Functional assessment and therapy methods are necessary for a client-centered approach that addresses the client's vocal needs across all environments. The purpose of this article is to present the approach with the intent to encourage discussion and implementation among educators, clinicians, researchers, and students. The functional approach is defined and its importance is described within the context of the World Health Organization's International Classification of Functioning, Disability, and Health with support provided by synchronous and asynchronous telepractice, the VoiceEvalU8 app, server, and web portal, and a framework that defines voice qualities (e.g., resonance, twang, loud, and others) by the anatomy and physiology of the voice production system (i.e., Estill Figures for Voice). Case scenarios are presented to highlight application of the functional voice approach.

Development and Validation of 2D-LiDAR-Based Gait Analysis Instrument and Algorithm

Acquiring gait parameters from usual walking is important to predict clinical outcomes including life expectancy, risk of fall, and neurocognitive performance in older people. We developed a novel gait analysis tool that is small, less-intrusive and is based on two-dimensional light detection and ranging (2D-LiDAR) technology. Using an object-tracking algorithm, we conducted a validation study of the spatiotemporal tracking of ankle locations of young, healthy participants (n = 4) by comparing our tool and a stereo camera with the motion capture system as a gold standard modality. We also assessed parameters including step length, step width, cadence, and gait speed. The 2D-LiDAR system showed a much better accuracy than that of a stereo camera system, where mean absolute errors were 46.2 ± 17.8 mm and 116.3 ± 69.6 mm, respectively. Gait parameters from the 2D-LiDAR system were in good agreement with those from the motion capture system (r = 0.955 for step length, r = 0.911 for cadence). Simultaneous tracking of multiple targets by the 2D-LiDAR system was also demonstrated. The novel system might be useful in space and resource constrained clinical practice for older adults.

Clinical characteristics of older patients with COVID-19: a systematic review of case reports

In the context of the current COVID-19 pandemic, higher morbidity and mortality have been reported in older adults. This age group presents physiological changes and its own clinical conditions such as frailty, dementia, among others.

OBJECTIVE

To describe the characteristics of COVID-19 patients, both over and under 80 years old, by conducting a systematic review of the literature describing case reports, and to summarize and critically assess these characteristics.

METHODS

Systematic review. The study was registered on the Registry of Health Research Projects (PRISA) of the Peruvian National Institute of Health (code EI00000631). Five electronic databases (Scopus, PubMed, PubMed Central, LILACS, and SCIELO) were systematically searched during the period between December 31, 2019 and April 16, 2020. The search focused on case reports, case studies, and case series of older people with COVID-19 infection aged over or under 80 years. When selecting the cases, priority was given to clinical and epidemiological profile, laboratory and imaging patterns, and comprehensive geriatric evaluation.

RESULTS

1,149 articles were identified; after applying the filters, a total of 15 publications of case reports and complete records of 27 older adults were obtained. The most frequent age group was between 60 to 69 years old. There is little literature regarding case reports of older adults aged over 80 years. The most frequent parameters were hypertension, fever, cough, respiratory distress, ground-glass opacification in chest radiography and tomography. Furthermore, decrease in PaO2/FiO2 ratio and lymphocytes, and increase in C-reactive protein and Interleukin 6 were observed.

CONCLUSIONS

This systematic review found little available information of patients under 80 years old, and far less for those over 80 years old, and an absence of comprehensive geriatric assessment.

Functional Age Predicted by Electronic Short Physical Performance Battery Can Detect Frailty Status in Older Adults

Purpose

The importance of evaluating frailty status of older adults in clinical practice has been gaining attention with cumulative evidence showing its relevance in clinical outcomes and decision-making. We aimed to develop and validate whether the functional age predicted by an electronic continuous short physical performance battery (eSPPB) could predict frailty status.

Patients and Methods

We reviewed medical records of outpatients (N=834) of Asan Medical Center, aged 51-95 years. We used the eSPPB data of 717 patients as a development cohort, and that of 117 patients, who also underwent comprehensive geriatric assessments, as a validation cohort. Frailty index was calculated by counting deficits of 45 geriatric items including comorbidities, daily functions, mobility, mood, and cognition. For functional age, we used balance score (0-4), gait speed (m/s), and stand-up time (s) measured 5 times in the chair rise test.

Results

From the development cohort, we established a functional age using the formula (83.61 - 1.98*[balance score] - 5.21*[gait speed] + 0.23*[stand-up time]), by multivariate linear regression analysis with chronological age as a dependent variable (R² = 0.233). In the validation cohort, the functional age positively correlated with frailty index (p < 0.001). C-statistics classifying frailty (defined as frailty index ≥0.25) was higher (p < 0.001) with functional age (0.912) than that with chronological age (0.637). A cut-off functional age of ≥77.2 years maximized Youden's J when screening for frailty, with sensitivity of 94.4% and specificity of 80.8%.

Conclusion

A newly developed functional age predictor using eSPPB parameters can predict the frailty status as defined by the deficit accumulation method and may serve as a physical biomarker of human aging.

Embedding and Sustaining a Focus on Function in Specialty Research and Care

Function and the independent performance of daily activities are of critical importance to older adults. Although function was once a domain of interest primarily limited to geriatricians, transdisciplinary research has demonstrated its value across the spectrum of medical and surgical care. Nonetheless, integrating a functional perspective into medical and surgical therapeutics has yet to be implemented consistently into clinical practice. This article summarizes the presentations and discussions from a workshop, "Embedding/Sustaining a Focus on Function in Specialty Research and Care," held on January 31 to February 1, 2019. The third in a series supported by the National Institute on Aging and the John A. Hartford Foundation, the workshop aimed to identify scientific gaps and recommend research strategies to advance the implementation of function in care of older adults. Transdisciplinary leaders discussed implementation of mobility programs and functional assessments, including comprehensive geriatric assessment; integrating cognitive and sensory functional assessments; the role of culture, environment, and community in incorporating function into research; innovative methods to better identify functional limitations, techniques, and interventions to facilitate functional gains; and the role of the health system in fostering integration of function. Workshop participants emphasized the importance of aligning goals and assessments and adopting a team science approach that includes clinicians and frontline staff in the planning, development, testing, and implementation of tools and initiatives. This article summarizes those discussions.

Frailty status and increased risk for falls: The role of anticholinergic burden

PURPOSE OF THE STUDY

Frailty leads to serious adverse outcomes including falls. The relationship between frailty and falls has not been evaluated in the context of the side effects of drugs with anticholinergic properties. The aim of this study was to examine the potential association of anticholinergic burden (ACB) with the risk of falls among frail older adults.

DESIGN AND METHODS

Community-dwelling older adults were consecutively selected from the geriatrics outpatient clinic. Based on a fall history in the last 12 months, the participants were grouped as fallers and non-fallers. Frailty status was assessed by Fried's phenotype method. Exposure to anticholinergic medications was estimated using the ACB scale, and the participants were classified into ACB_0 (none), ACB_1 (possible) and ACB_2+ (definite).

RESULTS

The study included 520 older adults (mean age 77.7 years, 62.7 % female), with a fall prevalence of 25.8 % 12 months past. The proportions of frailty and pre-frailty were 33.1 % and 57.4 %, respectively. After adjustment for study confounders, receiving at least 1 drug with either possible or definite anticholinergic properties was independently associated to falls in frail [OR = 3.84 (1.48-9.93), p = 0.006] and pre-frail participants [OR = 2.71 (1.25-5.89); p = 0.012], but not in robust subjects. Moreover, ACB was significantly associated with the frailty components on adjusted analysis (p's<0.05).

IMPLICATIONS

Current study showed that the use of any drugs with possible or definite anticholinergic properties was associated with an increased risk of falls in frail older adults. The results emphasize the importance of medication management with respect to fall prevention in these patients.

Intensive vs Standard Blood Pressure Control in Adults 80 Years or Older: A Secondary Analysis of the Systolic Blood Pressure Intervention Trial

OBJECTIVES

To evaluate the effect of intensive systolic blood pressure (SBP) control in older adults with hypertension, considering cognitive and physical function.

DESIGN

Secondary analysis.

SETTING

Systolic Blood Pressure Intervention Trial (SPRINT) PARTICIPANTS: Adults 80 years or older.

INTERVENTION

Participants with hypertension but without diabetes (N = 1167) were randomized to an SBP target below 120 mm Hg (intensive treatment) vs a target below 140 mm Hg (standard treatment).

MEASUREMENTS

We measured the incidence of cardiovascular disease (CVD), mortality, changes in renal function, mild cognitive impairment (MCI), probable dementia, and serious adverse events. Gait speed was assessed via a 4-m walk test, and the Montreal Cognitive Assessment (MoCA) was used to quantify baseline cognitive function.

RESULTS

Intensive treatment led to significant reductions in cardiovascular events (hazard ratio [HR] = .66; 95% confidence interval [CI] = .49-.90), mortality (HR = .67; 95% CI = .48-.93), and MCI (HR = .70; 95% CI = .51-.96). There was a significant interaction (P < .001) whereby participants with higher baseline scores on the MoCA derived strong benefit from intensive treatment for a composite of CVD and mortality (HR = .40; 95% CI = .28-.57), with no appreciable benefit in participants with lower scores on the MoCA (HR = 1.33 = 95% CI = .87-2.03). There was no evidence of heterogeneity of treatment effects with respect to gait speed. Rates of acute kidney injury and declines of at least 30% in estimated glomerular filtration rate were increased in the intensive treatment group with no between-group differences in the rate of injurious falls.

CONCLUSION

In adults aged 80 years or older, intensive SBP control lowers the risk of major cardiovascular events, MCI, and death, with increased risk of changes to kidney function. The cardiovascular and mortality benefits of intensive SBP control may not extend to older adults with lower baseline cognitive function.

Validation of a Multi-Sensor-Based Kiosk for Short Physical Performance Battery

OBJECTIVES

We aimed to validate a multi-sensor-based kiosk (automatically measured Short Physical Performance Battery [eSPPB] kiosk) that can perform automated measurement of the SPPB.

DESIGN

Prospective, cross-sectional study.

SETTING

Rehabilitation clinic of a tertiary-care hospital.

PARTICIPANTS

Ambulatory outpatients, aged 65 years or older (N = 40).

MEASUREMENTS

The eSPPB kiosk was developed to measure the three components of the SPPB: standing balance, gait speed, and chair stand test with embedded sensors and algorithms. Correlations between the total and component-specific scores of the eSPPB and manually measured SPPB (mSPPB), assessed by a physical therapist, were assessed. Further, correlations between SPPB parameters and geriatric functional measures were also evaluated.

RESULTS

This study included 40 participants with a mean age of 74.4 ± 6.5 years, a mean total eSPPB score of 10.1 ± 2.1, and a mean total mSPPB score of 10.2 ± 2.1. The intraclass correlation coefficient between the eSPPB and mSPPB total score was 0.97 (P < .001), and the κ agreement was 0.79 (P < .001). The intraclass coefficients between the components of eSPPB and mSPPB were 0.77 (P < .001), 0.88 (P < .001), and 0.99 (P < .001) for standing balance, gait speed, and chair stand test, respectively.

CONCLUSION

The newly developed kiosk might be a viable and efficient method for performing the SPPB in older adults. J Am Geriatr Soc 67:2605-2609, 2019.
