Physical activity and sedentary behaviour interventions for people living with both frailty and multiple long-term conditions and their informal carers: a scoping review and stakeholder consultation

INTRODUCTION

This scoping review mapped evidence on physical activity (including structured exercise) and sedentary behaviour interventions (interventions to reduce sedentary behaviour) in people living with both frailty and multiple long-term conditions (MLTCs) and their informal carers.

METHODS

Ten databases and grey literature were searched from 2000 to October 2023. Two reviewers screened studies and one extracted data. Results were shared with three stakeholder groups (n = 21) in a consultation phase.

RESULTS

After screening, 155 papers from 144 studies (1 ongoing) were retained. The majority were randomised controlled trials (86, 55%). Participants' mean age was 73 ± 12 years, and 73% were of White ethnicity. MLTC and frailty measurement varied widely. Most participants were pre-to-moderately frail. Physical health conditions predominated over mental health conditions.Interventions focused on structured exercise (83 studies, 60%) or combined interventions (55 studies, 39%). Two (1%) and one (0.7%) focused solely on habitual physical activity or sedentary behaviour. Adherence was 81% (interquartile range 62%-89%) with goal setting, monitoring and support important to adherence. Carers were only involved in 15 (11%) studies. Most interventions reported positive outcomes, primarily focusing on body functions and structures.

CONCLUSIONS

A modest volume of evidence exists on multicomponent structured exercise interventions, with less focus on habitual physical activity and sedentary behaviour. Interventions report largely positive effects, but an updated systematic review is required. The field could be advanced by more rigorous characterisation of MLTCs, socioeconomic status and ethnicity, increased informal carer involvement and further evaluation of habitual physical activity and sedentary behaviour interventions.

Frailty Detection in Older Adults with Diabetes: A Scoping Review of Assessment Tools and Their Link to Key Clinical Outcomes

Objectives: With the increasing prevalence of diabetes and frailty among older adults, there is an urgent need for precision medicine that incorporates comprehensive geriatric assessments, including frailty detection. This scoping review aims to map and synthesize the available evidence on validated tools for detecting pre-frailty and frailty in community-dwelling elderly individuals with diabetes and outpatient diabetes patients. Specifically, it addresses: (1) What validated tools are available for detecting pre-frailty and frailty in this population? (2) How are these tools associated with outcomes such as glycemic control, hypoglycemia, and metabolic phenotypes? (3) What gaps exist in the literature regarding these tools? Methods: The review followed PRISMA-ScR guidelines, conducting a systematic search across PubMed, Cochrane Library, and Web of Science. The inclusion criteria focused on studies involving individuals aged 70 years and older with diabetes, emphasizing tools with predictive capacity for disability and mortality. Results: Eight instruments met the inclusion criteria, including the Frailty Index, Physical Frailty Phenotype, and Clinical Frailty Scale. These tools varied in domains such as physical, psychological, and social aspects of frailty and their association with glycemic control, hypoglycemia, and metabolic phenotypes. The review identified significant gaps in predicting diabetes-related complications and their clinical application. Conclusions: Routine management of older adults with diabetes should incorporate frailty detection, as it is crucial for their overall health. Although widely used, the reviewed tools require refinement to address the unique characteristics of this population. Developing tailored instruments will enhance precision medicine, leading to more effective, individualized interventions for elderly individuals with diabetes.

The outcome of frailty in older people with diabetes as a function of glycaemic control and hypoglycaemic therapy: a review

INTRODUCTION

Frailty is an emerging and newly recognized complication of diabetes in older people. However, frailty is not thoroughly investigated in diabetes outcome studies.

AREAS COVERED

This manuscript reviews the effect of glycemic control and hypoglycemic therapy on the incidence of frailty in older people with diabetes.

EXPERT OPINION

Current studies show that both low glycemia and high glycemia are associated with frailty. However, most of the studies, especially low glycemia studies, are cross-sectional or retrospective, suggesting association, rather than causation, of frailty. In addition, frail patients in the low glycemia studies are characterized by lower body weight or lower body mass index (BMI), contrary to those in the high glycemia studies, who are either overweight or obese. This may suggest that frailty has a heterogeneous metabolic spectrum, starting with an anorexic malnourished (AM) phenotype at one end, which is associated with low glycemia and a sarcopenic obese (SO) phenotype on the other end, which is associated with high glycemia. The current little evidence suggests that poor glycemic control increases the risk of frailty, but there is a paucity of evidence to suggest that tight glycemic control would reduce the risk of incident frailty. Metformin is the only well-studied hypoglycemic agent, so far, to have a protective effect against frailty independent of glycemic control in the non-frail older people with diabetes. However, once frailty is developed, the choice of the best hypoglycemic agent for these patients will be affected by the metabolic phenotype of frailty. For example, sodium glucose transporter-2 (SGLT-2) inhibitors and glucagon-like peptide-1 receptor agonists (GLP-1RA) are appropriate in the SO phenotype due to their weight losing properties, while insulin therapy may be considered early in the AM phenotype due to its anabolic and weight gaining benefits. Future studies are still required to further investigate the metabolic effects of frailty on older people with diabetes, determine the most appropriate HbA1c target, and explore the most suitable hypoglycemic agent in each metabolic phenotype of frailty.

Predictors of frailty among Chinese community-dwelling older adults with type 2 diabetes: a cross-sectional survey

OBJECTIVES

To assess the prevalence of frailty and identify predictors of frailty among Chinese community-dwelling older adults with type 2 diabetes.

DESIGN

A cross-sectional design.

SETTING

Two community health centres in central China.

PARTICIPANTS

291 community-dwelling older adults aged ≥65 years with type 2 diabetes.

MAIN OUTCOME MEASURES

Data were collected via face-to-face interviews, anthropometric measurements, laboratory tests and community health files. The main outcome measure was frailty, as assessed by the frailty phenotype criteria. The multivariate logistic regression model was used to identify the predictors of frailty.

RESULTS

The prevalence of prefrailty and frailty were 51.5% and 19.2%, respectively. The significant predictors of frailty included alcohol drinking (ex-drinker) (OR 4.461, 95% CI 1.079 to 18.438), glycated haemoglobin (OR 1.434, 95% CI 1.045 to 1.968), nutritional status (malnutrition risk/malnutrition) (OR 8.062, 95% CI 2.470 to 26.317), depressive symptoms (OR 1.438, 95% CI 1.166 to 1.773) and exercise behaviour (OR 0.796, 95% CI 0.716 to 0.884).

CONCLUSIONS

A high prevalence of frailty was found among older adults with type 2 diabetes in the Chinese community. Frailty identification and multifaceted interventions should be developed for this population, taking into consideration proper glycaemic control, nutritional instruction, depressive symptoms improvement and enhancement of self-care behaviours.

A geriatrics walking clinic improves hemoglobin A1c and timed gait in older veterans with type 2 diabetes

Over one quarter of older adults in the U.S. has diabetes; and, physical activity is important for the promotion of healthy aging in this population. The purpose of this clinical demonstration project is to evaluate the effect of physical activity in the form of walking on glycemic control and timed gait in older Veterans with type 2 diabetes (T2D). Veterans aged ≥60 years were enrolled in the Geriatrics Walking Clinic (GWC), a clinical demonstration project, at South Texas Veterans Health Care System. GWC is a 6-week clinical program that promotes physical activity and is delivered by a registered nurse/diabetes educator and geriatrician. Veterans were recruited from the VA clinics. Enrolled patients received a pedometer at an initial face-to-face visit, were followed with weekly phone calls to monitor steps/day, received encouragement, and participated in a final face-to-face visit at the end of 6 weeks. In a sub-set of patients with T2D, we performed a chart review and recorded Hemoglobin A1c (HbA1c) at 3, 6, and 12 months after completion of the program. Timed Gait, a major characteristic of frailty, was measured at baseline and after completing the program. Change in HbA1c and timed gait compared to baseline was examined using paired t-tests. Sixty-two patients had HbA1c values available and were included in this analysis. Of these, 36, 52, and 61 patients had repeat HbA1c at 3, 6, and 12 months after the intervention, respectively. Mean age was 68 ± 6 years, 58% were Hispanic, and 92% males. HbA1c improved at 3 months (-0.49, 95% CI: -0.87 to -0.12, p=0.013), at 6 months (-0.40, 95% CI: -0.68 to -0.12, p=0.006), and at 12 months (-0.30, 95% CI: -0.57 to -0.029, p=0.031) compared to baseline. Timed Gait also improved (9.3 ±1.7 vs. 10.2 ±1.8, p<0.001). The finding highlights that older patients with T2D benefit from a GWC with improved glycemic control and timed gait.

Understanding Diabetes-Related Distress Characteristics and Psychosocial Support Preferences of Urban African American Adults Living With Type 2 Diabetes: A Mixed-Methods Study

Purpose The purpose of this study is to understand diabetes-related distress (DRD) characteristics and identify psychosocial support preferences of urban African American adults living with type 2 diabetes (T2DM). Methods A 2-phase, mixed-methods sequential explanatory study design was used to gather data. In phase 1, a purposive sample of participants (N = 155) was recruited and asked to complete a written survey. The Diabetes Distress Scale (DDS17) was used to assess DRD, including subscales-emotional burden (EB), regimen distress (RD), interpersonal distress (ID), and physician distress (PD). In phase 2, a subset of phase 1 participants (N = 23) volunteered to attend 1 of 4 gender-stratified follow-up focus groups to contextualize the quantitative survey results. Results Survey findings indicate that on average, participants had moderate levels of DRD (aggregate), RD, and EB but had low ID and PD. During follow-up focus groups, participants described RD and EB as their primary distress types and emphasized that clinicians should prioritize the mental health aspects of T2DM similarly to its physical aspects. Participants expressed a desire for culturally appropriate peer support groups as a psychosocial support resource for distress coping and specifically requested the development of gender-stratified groups and groups for young adults. Conclusions Results support the need to screen for and address diabetes-related distress among African American patients with T2DM. Findings also inform the development of culturally appropriate psychosocial support resources to facilitate diabetes-related distress coping.

Impact of multimorbidity on healthcare professional task shifting potential in patients with type 2 diabetes in primary care: a French cross-sectional study

OBJECTIVES

To estimate the transferability of processes of care from general practitioners (GPs) to allied healthcare professionals and the determinants of such transferability.

DESIGN

French national cross-sectional multicentre study SETTING: 128 family practices providing supervised training for residents in general practice.

PARTICIPANTS

All patients consulting with their GP over a total number of 20 days (ie, 1 day a week from December 2011 to April 2012). Encounters where type 2 diabetes was one of the managed health problems were selected for analysis.

PRIMARY AND SECONDARY OUTCOME MEASURES

Processes that were associated with specific health problems were collected by 54 residents. Potential process transferability was the main outcome assessed, as well as the professionals involved in the collaboration and the eventual conditions associated with transfer.

RESULTS

From 8572 processes of care that concerned 1088 encounters of patients with diabetes, 21.9% (95% CI 21.1% to 22.8%) were considered eligible for transfer from GPs to allied healthcare professionals (78.1% to nurses, 36.7% to pharmacists). Processes were transferable with condition(s) for 70.6% (ie, a protocol, shared record or supervision). The most transferable processes concerned health maintenance (32.1%) and cardiovascular risk factors (hypertension (28.7%), dyslipidaemia (25.3%) and diabetes (24.3%)). Multivariate analysis showed that educational processes or a long-term condition status were associated with increased transferability (OR 3.26 and 1.47, respectively), whereas patients with higher intellectual occupations or those with two or more associated health problems were associated with lower transferability (OR 0.33 and 0.81, respectively).

CONCLUSIONS

A significant part of GP activity relating to patients with multimorbidity including type 2 diabetes could be transferred to allied healthcare professionals, mainly on prevention and global education to cardiovascular risk factors. The organisational and finance conditions of team work as views of patients and healthcare professionals must be explored before implementation in primary care.

The ACHRU-CPP versus usual care for older adults with type-2 diabetes and multiple chronic conditions and their family caregivers: study protocol for a randomized controlled trial

BACKGROUND

Many community-based self-management programs have been developed for older adults with type-2 diabetes mellitus (T2DM), bolstered by evidence from randomized controlled trials (RCTs) that T2DM can be prevented and managed through lifestyle modifications. However, the evidence for their effectiveness is contradictory and weakened by reliance on single-group designs and/or small samples. Additionally, older adults with multiple chronic conditions (MCC) are often excluded because of recruiting and retention challenges. This paper presents a protocol for a two-armed, multisite, pragmatic, mixed-methods RCT examining the effectiveness and implementation of the Aging, Community and Health Research Unit-Community Partnership Program (ACHRU-CPP), a new 6-month interprofessional, nurse-led program to promote self-management in older adults (aged 65 years or older) with T2DM and MCC and support their caregivers (including family and friends).

METHODS/DESIGN

The study will enroll 160 participants in two Canadian provinces, Ontario and Alberta. Participants will be randomly assigned to the control (usual care) or program study arm. The program will be delivered by registered nurses (RNs) and registered dietitians (RDs) from participating diabetes education centers (Ontario) or primary care networks (Alberta) and program coordinators from partnering community-based organizations. The 6-month program includes three in-home visits, monthly group sessions, monthly team meetings for providers, and nurse-led care coordination. The primary outcome is the change in physical functioning as measured by the Physical Component Summary (PCS-12) score from the short form-12v2 health survey (SF-12). Secondary client outcomes include changes in mental functioning, depressive symptoms, anxiety, and self-efficacy. Caregiver outcomes include health-related quality of life and depressive symptoms. The study includes a comparison of health care service costs for the intervention and control groups, and a subgroup analysis to determine which clients benefit the most from the program. Descriptive and qualitative data will be collected to examine implementation of the program and effects on interprofessional/team collaboration.

DISCUSSION

This study will provide evidence of the effectiveness of a community-based self-management program for a complex target population. By studying both implementation and effectiveness, we hope to improve the uptake of the program within the existing community-based structures, and reduce the research-to-practice gap.

The Aging, Community and Health Research Unit-Community Partnership Program for older adults with type 2 diabetes and multiple chronic conditions: a feasibility study

BACKGROUND

Few studies have examined the effectiveness of community-based self-management interventions in older adults with type 2 diabetes mellitus (T2DM) and multiple chronic conditions (MCC). The objectives of this study were to examine the feasibility of implementation in practice (primary) and the feasibility of study methods and potential effectiveness (secondary) of the Aging, Community and Health-Community Partnership Program, a new 6-month interprofessional, nurse-led program to promote diabetes self-management in older adults (>65 years) with T2DM and MCC.

METHODS

This study used a prospective one-group pre-test/post-test design. Participants were recruited from a specialized diabetes clinic. They received a median of three in-home/clinic visits by certified diabetes educators (CDEs) and attended a median of three group wellness sessions provided by the CDEs in partnership with a community-based seniors' association. The primary outcome was the feasibility of the program (acceptability, fidelity, implementation barriers/facilitators). Secondary outcomes included the feasibility of the study methods (recruitment/retention rates and procedures, eligibility criteria, data collection and analysis methods) and potential effectiveness of the program based on 6-month changes in self-reported outcomes including self-management behavior (diet, exercise, self-monitoring), health status (quality of life, mental health), and costs of service use. Analysis of feasibility outcomes was primarily based on descriptive statistics. The potential effectiveness of the program was explored using different tests, with the results expressed using descriptive statistics and effect estimates (95 % confidence intervals).

RESULTS

In total, 45 (88 %) of 51 eligible persons consented to participate. Of these, 37 (82 %) completed the 6-month follow-up. Participants and providers viewed the program as acceptable and feasible. Participants had a higher SF-12 physical component summary score at 6 months compared with baseline (mean score difference 3.0, 95 % CI 0.2-5.8). Median costs for diabetes care increased over 6 months (reflecting inclusion of program costs), while other service costs either decreased or remained unchanged.

CONCLUSIONS

This study offers preliminary evidence that the program was feasible to deliver and acceptable to participants and providers. Initial results suggest that the program may improve physical functioning. A randomized controlled trial is feasible, with some adaptations to the program and study methods that were identified from this feasibility study.

Frailty, Diabetes, and Mortality in Middle-Aged African Americans

BACKGROUND

Older adult frail diabetics have high mortality risk, but data are limited regarding frail late middle-aged diabetics, especially for African-Americans. The aim of this study is to examine the association of diabetes with health outcomes and frailty in the African American Health (AAH) study.

METHODS

AAH is a population-based longitudinal cohort study. Participants were African Americans (N=998) ages 49 to 65 years at baseline. Cross-sectional comparisons for diabetes included disability, function, physical performance, cytokines, and frailty. Frailty measures included the International Academy of Nutrition and Aging [FRAIL] frailty scale, Study of Osteoporotic Fractures [SOF] frailty scale, Cardiovascular Health Study [CHS] frailty scale, and Frailty Index [FI]). Longitudinal associations for diabetes included new ADLs ≥ 1 and mortality at 9-year follow-up.

RESULTS

Diabetics were more likely to be frail using any of the 4 frailty scales than were non-diabetics. Frail diabetics, compared to nonfrail diabetics, reported significantly increased falls in last 1 year, higher IADLs and higher LBFLs. They demonstrated worse performance on the SPPB, one-leg stand, and grip strength; and higher Tumor Necrosis Factor receptors (sTNFR1 and sTNFR2). Mortality and 1 or more new ADLs also were increased among frail compared to nonfrail diabetics when followed for 9 years.

CONCLUSIONS

Frailty in middle-aged African American persons with diabetes is associated with having more disability and functional limitations, worse physical performance, and higher cytokines (sTNFR1 and sTNFR2 only). Middle-aged African Americans with diabetes have an increased risk of mortality and frail diabetics have an even higher risk of death, compared to nonfrail diabetics.

Diabetes and risk of frailty and its potential mechanisms: a prospective cohort study of older adults

BACKGROUND

There is emerging evidence of the role of diabetes as a risk factor for frailty. However, the mechanisms of this association are uncertain.

METHODS

Prospective cohort study of 1750 noninstitutionalized individuals aged 60 years or older recruited in 2008-2010. At baseline, information was obtained on health behaviors, morbidity, cardiometabolic biomarkers, and antidiabetic treatments. Individuals were considered diabetic if they reported a physician diagnosis or had fasting serum glucose of 126 mg/dL or higher. Study participants were followed through 2012 to assess incident frailty, defined as at least 3 of the 5 Fried criteria.

RESULTS

At baseline, the cohort included 346 individuals with diabetes and 1404 without diabetes. Over a mean 3.5-year follow-up, 115 cases of incident frailty were ascertained. After adjustment for age, sex, and education, participants with diabetes showed an increased risk of frailty (odds ratio [OR] 2.18, 95% confidence interval [CI] 1.42-3.37). Additional adjustment for health behaviors and abdominal obesity yielded a 29.7% reduction in the OR (OR 1.83, 95% CI 1.16-2.90). Subsequent adjustment for morbidity produced an additional 8.4% reduction (OR 1.76, 95% CI 1.10-2.82), and for cardiometabolic biomarkers, a further 44% reduction (OR 1.32, 95% CI 0.70-2.49). In particular, adjustment for HbA1c, lipoproteins, and triglycerides accounted for the greatest reductions. Finally, additional adjustment for oral antidiabetic medication reduced the OR to 1.01 (95% CI 0.46-2.20), whereas adjustment for nutritional therapy increased the OR to 1.64 (95% CI 0.77-3.49).

CONCLUSIONS

Diabetes mellitus is associated with higher risk of frailty; this association is partly explained by unhealthy behaviors and obesity and, to a greater extent, by poor glucose control and altered serum lipid profile among diabetic individuals. Conversely, diabetes nutritional therapy reduces the risk of frailty.

Minimally Disruptive Medicine: A Pragmatically Comprehensive Model for Delivering Care to Patients with Multiple Chronic Conditions

An increasing proportion of healthcare resources in the United States are directed toward an expanding group of complex and multimorbid patients. Federal stakeholders have called for new models of care to meet the needs of these patients. Minimally Disruptive Medicine (MDM) is a theory-based, patient-centered, and context-sensitive approach to care that focuses on achieving patient goals for life and health while imposing the smallest possible treatment burden on patients’ lives. The MDM Care Model is designed to be pragmatically comprehensive, meaning that it aims to address any and all factors that impact the implementation and effectiveness of care for patients with multiple chronic conditions. It comprises core activities that map to an underlying and testable theoretical framework. This encourages refinement and future study. Here, we present the conceptual rationale for and a practical approach to minimally disruptive care for patients with multiple chronic conditions. We introduce some of the specific tools and strategies that can be used to identify the right care for these patients and to put it into practice.
