Challenges and strategies pertaining to recruitment and retention of frail elderly in research studies: A systematic review

How do aging, socioeconomic status, and gender affect verbal fluency, cognitive skills, depression, and daily living activities in older people?

Introduction: Old age is a period associated with health risks, leading to losses in various skills. Aim: This study aims to examine the verbal fluency and cognitive skills of older individuals, their levels of depression, and daily living activities as well as to identify the correlations between these and some other variables. Method: 77 participants (48 F; 29 M) aged 65 and over who had not received a diagnosis were administered a "ParticipantInformation Form", "Verbal Fluency Test", "Montreal Cognitive Assessment Turkish Version (MOBID)", "Geriatric Depression Scale (GDS)", and "Barthel Index of Basic Activities of Daily Living (ADL)". Statistical analysis of the research data was performed using IBM SPSS 24.0 software. Results: There was a moderate, significant positive correlation between verbal fluency scores and both MOBID (r = 0.542, r = 0.604, r = 0.343) and ADL scores (r = 0.365, r = 0.323, r = 0.254), whereas a moderate, significant negative correlation was found between verbal fluency scores and GDS scores (r = -0.551, r = -0.422, r = -0.493). s (Verbal fluency and MOBID scores showed significant differences across age groups, whereas ADL and depression scores did not; additionally, verbal fluency, MOBID, and GDS varied significantly by education and income levels while ADL scores remained unaffected; notably, only verbal fluency scores differed by gender, with female participants demonstrating higher performance. Conclusion: Significant correlations were observed between verbal fluency, cognition, depression, and daily living activity skills. As the cognitive and daily living activity skills of participants increase or their levels of depression decrease, their verbal fluency skills improve. The findings underscore the importance of supporting all variables and highlight the significance of interdisciplinary collaboration.

Systematic review of clinical effectiveness of interventions for treatment resistant late-life depression

BACKGROUND

Treatment-resistant late-life depression (TRLLD) affects nearly half of older adults with major depression. This systematic review evaluates published evidence of effectiveness of both pharmacological and non-pharmacological treatments for TRLLD.

METHODS

A search of MEDLINE, EMBASE, CINAHL, PsycINFO, the Cochrane Library, and online trial registries up to March 2024 was conducted to identify randomized controlled trials (RCTs) evaluating pharmacological and non-pharmacological interventions for TRLLD.

RESULTS

Seven studies assessed the effectiveness of pharmacological interventions (antidepressants, antipsychotics, mood stabilizers, or ketamine) and another seven examined non-pharmacological approaches (psychotherapy, electroconvulsive therapy, repetitive transcranial magnetic stimulation (rTMS), and computerized cognitive remediation). Aripiprazole (2 studies), venlafaxine (1 study), ketamine (1 study), and lithium (1 study) were associated with a reduction in depressive symptoms post-treatment compared to the comparator treatment group. rTMS (2 studies), sequential bilateral theta burst stimulation (1 study) and cognitive remediation (1 study) also showed significant improvements in depressive symptoms post-treatment compared to a comparator treatment group. Quality of evidence varied from very low to medium among the included studies. Most studies reported data on small sample sizes.

CONCLUSIONS AND IMPLICATIONS

We identified a small number of RCTs evaluating treatments for TRLLD. Aripiprazole augmentation appears to be an effective treatment based on two studies, with an acceptable side effect profile. Other treatments may be effective, but the evidence is based on very low-quality evidence. Future large-scale RCTs are urgently needed to draw firm conclusions.

FEASIBILITY OF AN INTERACTIVE VIDEO-BASED TRAINING PROGRAM FOR LEARNING AND REVIEWING WALKING AID SKILLS

OBJECTIVES

1) To assess the feasibility of a trial with a novel interactive video-based mobile application to teach safe walking aid use. 2) To explore the preliminary impact of the novel application on balance confidence, balance, mobility, and endurance.

DESIGN

Single-arm, pre-post feasibility study.

SETTING

University research laboratory.

PARTICIPANTS

Adult walking aid users (N=13).

INTERVENTION

Participants used the novel application's fitting and gait training modules pertaining to their walking aid on two occasions (baseline, 2 weeks).

OUTCOME MEASURES

Trial feasibility indicators were collected for process (recruitment rate, consent rate, and retention rate), resources (duration of each data collection session), management (participant processing time), and safety. At baseline and at 2 weeks, participants completed the Activities-specific Balance Confidence (ABC) Scale, the Berg Balance Scale (BBS), the Timed-Up-and-Go (TUG), and the 2-minute Walk Test (2MWT).

RESULTS

Thirteen walking aid users (7 males; mean±SD age 55±15 years; mean±SD duration of walking aid use: 2.7±4.0 years) participated. Feasibility was attained on 3 out of the 6 trial feasibility indicators. Participants achieved statistically significant improvements in balance confidence (ABC; small to medium effect; p<0.001) and balance (BBS; small effect; p<0.001). Participants did not experience significant changes in mobility (TUG; no effect) or endurance (2MWT; small effect; p=0.25).

CONCLUSION

Based on our criteria, a trial with the novel application may be feasible, with some modifications. Preliminary improvements in clinically relevant outcomes including balance confidence and balance were found. These findings will help inform a randomized controlled trial to evaluate the effect of the application on clinical outcomes.

The selection of participants for interventional microbiota trials involving cognitively impaired older adults

Gut microbiota plays a significant role in nutrient extraction, metabolism, and immune function. Thus, the growing number of microbiome studies seek to link the presence and prevalence of specific bacteria, fungi, and viruses with a variety of physiological and disease outcomes. However, recruiting a diverse group of patients has been a challenge. Poor hearing and vision, lack of transportation, cognitive impairment, and a non-English primary language may interfere with patient enrollment as well as adherence to the requirements of a Microbiome study. Much of what we do know about diseases in older adults comes from studies that exclude many of these patients commonly encountered in clinical practice. The purpose of this review article is to highlight recruitment and retention strategies for engaging people who typically do not participate in microbiome studies, and it seeks to develop and explicate inclusion and exclusion criteria to promote more robust study results.

Getting fit for hip and knee replacement: The Fit-Joints multimodal intervention for frail patients with osteoarthritis - a pilot randomized controlled trial

BACKGROUND

Older adults with frailty have high risk for poor postoperative outcomes.

OBJECTIVE

To evaluate the feasibility of a multimodal prehabilitation program in older adults with frailty awaiting hip or knee replacement.

DESIGN

Parallel two-arm randomized controlled pilot trial.

PARTICIPANTS AND SETTING

Community-dwelling older adults with frailty awaiting joint replacement aged ≥60 years recruited from the Musculoskeletal Central Intake and Assessment Centre (MSK CIAC), Ontario.

INTERVENTION

Exercise, protein and vitamin D supplements, and medication review.

MEASUREMENT

Feasibility was assessed based on predefined progression criteria for recruitment, retention, data completion and adherence to intervention components. Clinical outcomes including Oxford Knee and Hip Scores, frailty index, Short Physical Performance Battery and health-related quality of life were collected at baseline, 1-week preoperative, 6-weeks and 6-months postoperative and were evaluated using generalized linear mixed models for repeated measures.

RESULTS

A total of 69 participants were enrolled. Recruitment rate was 35 %. Participants' mean age was 74 (standard deviation (SD): 7.5); 51 % were prefrail and 36 % were frail. Participant retention was 81 %, and data completion was ≥80 %. Mean adherence to strength exercises was 4 days (95 % confidence interval (CI): 3-5 days/week), balance 3 days (95 % CI: 2-4 days/week), and flexibility 3 days (95 % CI: 3-4 days/week). Adherence to vitamin D intake was 82 % (95 % CI: 73-92 %), and medication review consultation completion was 86 % (95 % CI: 68-95 %). These outcomes met the target values for feasibility success. The Oxford Knee Score at 6-months postoperative 8.78 (95 % CI: 0.40-17.16) showed a clinically meaningful and statistically significant difference between treatment groups. There were also indications of clinically relevant changes for frailty and quality of life post-surgery.

CONCLUSION

This trial provides strong evidence of feasibility and indications of improvements in postoperative clinical outcomes. Challenges to implementation and adherence were identified that can inform modifications to study design for future trials.

Factors Associated With Enrollment to a Decentralized Study

OBJECTIVE

To assess whether the mode and formatting of invitations affect enrollment in a large, decentralized study.

PATIENTS AND METHODS

Between July 1, 2022, and October 30, 2022, we prospectively compared various approaches to enroll patients in the Tapestry DNA Sequencing Research Study, a decentralized exome-sequencing study. In phase 1, patients were randomized to receive invitations via the electronic health record (EHR) patient portal or email (cohort 1, 69,852 patients). Phase 2 randomized in a 2×2 factorial design to receive (by portal or email) standard or enhanced (ie, more visually appealing) invitations (cohort 2, 26,198 patients). Factors that predicted enrollment rates were analyzed.

RESULTS

The enrollment rate was greater in cohort 2 (1,785 of 24,550, 7.27%) than 1 (1,758 or 69,765, 2.52%) and remained significant after multivariable adjustment (odds ratio, 1.31; 95% CI, 1.19-1.45). Enrollment rates were greater in women than men, patients 50 to 70 years of age than younger patients, White or non-Hispanic or Latino patients than those in other racial categories, urban than rural residents, and patients who had more health care encounters or more recent health care before this study (P<.02). The enrollment rate was also greater when invitations were delivered via EHR than email (odds ratio, 1.56; 95% CI, 1.44-1.68; P<.001).

CONCLUSION

Invitations via EHR rather than email facilitate enrollment to large, decentralized studies. Enhanced display of invitation material did not increase enrollment. Lower enrollment rates in men, younger individuals, non-White and Hispanic individuals, and rural residents highlight a continued need to focus enrollment strategies on these subgroups.

Frailism: a scoping review exploring discrimination against people living with frailty

People living with frailty can experience discrimination, but unlike the characteristics of age and disability, frailty is not protected by law. Frailty is a clinical syndrome associated with ageing in which health deficits increase a person's vulnerability to illness, disability, and death. This scoping review, conducted by a team of methodologists, clinicians, lawyers, and patients, aimed to investigate the extent of discrimination against people living with frailty described in health-care literature. We searched five health-care databases from inception up to June, 2022, and grey literature, to identify 144 texts. The texts were classified by the types of discrimination (direct discrimination, indirect discrimination, harassment, and victimisation) and inductively developed into contextual themes. The median age of the participants was 77 years (IQR 69·9-82·0), and 65·4% were women. The most common types of discrimination were direct (in 90 [63%]), indirect (in 66 [46%]), and harassment (in one [1%]) of the 144 texts, with no instances of victimisation reported. Nine themes of discriminatory actions were developed. Discrimination against people living with frailty overlapped with discrimination based on established protected characteristics, including age, disability, race, and sex. Evidence indicated that frailty discrimination replaces, mediates, masks, and potentiates age discrimination. Discrimination against people with frailty seemed to be both an independent event and one that interacts with established protected characteristics. Future research should focus on preventing frailty-based discrimination and establishing whether frailty should be considered a new protected characteristic by law.

Perceived barriers and facilitators of staff recruiting participants to a randomised controlled trial of a community rehabilitation intervention following hip fracture

BACKGROUND

Randomised controlled trials (RCTs) often struggle with recruitment and many need extensions which leads to delayed implementation of effective interventions. Recruitment to complex intervention trials have similar difficulties. Alongside this, the COVID-19 pandemic had a major impact upon trial recruitment. Research has shown that many other recruitment issues can be anticipated, for example overestimating target population prevalence; however, a range of factors may play a role. The aim of this study is to investigate facilitators and barriers to recruitment from the perspective of the recruiter.

METHODS

Fracture in the Elderly Multidisciplinary Rehabilitation - phase III (FEMuR III) was a RCT of a complex intervention post-surgery for hip fracture in patients over 60 years old. A process evaluation was undertaken, and semi-structured interviews were conducted with seven recruiters between November 2022 and March 2023 to identify barriers and facilitators to recruitment. A thematic analysis was undertaken in NVIVO (Version 12) using a critical realist perspective.

RESULTS

The trial took place mostly during the COVID-19 pandemic, and the unique impact of this on reported barriers is considered. A key finding included recruiter reluctance to approach patients that they felt would not benefit from the trial due to other factors (e.g. comorbidities or complex living situations). A possible barrier to recruiting carers appeared to be that family members did not relate to the label of 'carer' and so did not take part. Facilitators included recruiters approaching patients with other clinical or research staff. This approach, which included tailored initial information on the trial, reduced participant stress by increasing patient familiarity with recruiting staff and allowing staff time to develop relationships with patients.

CONCLUSION

This paper identifies barriers and facilitators of recruitment to FEMuR III with six broad themes for both barriers and facilitators identified in the qualitative data synthesis. The impact of the COVID-19 pandemic was the main, but not sole, barrier to recruitment. Key findings concern reluctance to approach some eligible patients, the label of 'carer', the involvement of clinical staff and patient preference for trial group. Strategies to identify and overcome recruitment problems are highlighted and should be implemented and evaluated in further RCTs of complex interventions.

Predictors of Retention in the 1Florida Alzheimer's Disease Research Center (ADRC) Over Two Waves

Background: Attrition is a significant methodological concern in longitudinal studies. Sample loss can limit generalizability and compromise internal validity. Methods: Wave one (n = 346) and wave two follow-ups (n = 196) of the 1Florida ADRC clinical core were examined using a 24-month visit window. Results: The sample (59% Hispanic) demonstrated retention rates of 77.2% and 86.2% in waves one and two, respectively. Predictors of lower retention in wave one included older age, amnestic MCI or dementia, and lower cognition and function scores. Completing a baseline MRI and lack of hippocampal atrophy were associated with higher retention in both waves. In wave two, a greater neighborhood disadvantage score was associated with attrition. Discussion: Predictors of retention changed over time, possibly due to the early withdrawal of the most vulnerable in the initial wave. Understanding predictors of retention can facilitate retention strategies, reduce attrition, and increase the validity of findings.

The feasibility and acceptability of engaging older adults living with multiple long-term conditions, frailty, and a recent deterioration in health in research: Findings from the Lifestyle in Later Life - Older People's Medicine (LiLL-OPM) study

BACKGROUND

Older adults living with multiple long-term conditions (MLTC, also known as multimorbidity) and frailty are more likely to experience a deterioration in their health requiring specialist referral or hospital admission than individuals without these syndromes. However, this group of older people are underserved by research meaning that there is a limited evidence base for their care. This study therefore aimed (1) to determine if it is feasible to recruit and collect quantitative data to describe the health and lifestyle of older adults living with MLTC, frailty and a recent deterioration in health and (2) to assess if taking part in research is acceptable to this group of older adults.

METHODS

Participants were approached and recruited for this study via an Older People's Medicine Day Unit in Newcastle upon Tyne, UK. The study took a mixed methods approach, involving quantitative and qualitative data collection. To determine the feasibility of carrying out research in this group, we quantified recruitment rate and collected data on the health and lifestyle, including diet and physical activity, of the participants. Qualitative semi-structured interviews were undertaken to assess acceptability. Two separate interviews were carried out focusing on involving older adults in research and the participants' experiences of taking part in the research. Interviews were analysed using thematic analysis.

RESULTS

Fifty patients were approached to participate in the study with twenty-nine (58%) successfully recruited. It was feasible to collect information to describe the health and lifestyle of these older adults who demonstrated very low levels of physical activity. Participants reported that taking part in the research was acceptable to them with interview analysis generating three themes (1) developing a meaningful partnership, (2) enabling factors to participation: research at home with flexible delivery and (3) social and psychological benefits of research participation.

CONCLUSIONS

It is feasible and acceptable to recruit and carry out research with this underserved group of older adults. Participants found taking part in this research to be acceptable and reported overall positive experiences of their involvement in the study and indicated that they would be willing to contribute to further research in the future.

Somatosensory and dynamic balance improvement in older adults with diabetic peripheral neuropathy through sensorimotor exercise: A multisite randomized controlled trial

PURPOSE

To examine the effect of the Feldenkrais method on lower legs and foot somatosensory postural control-related function, dynamic balance, fear of falling and quality of life in adults with diabetic polyneuropathy in the short and mid-term.

METHODS

A single-blinded, parallel, multicentric randomized control trial was conducted in two health hospitals. Subjects with diabetic polyneuropathy and older than 55 years with a history of falls or dynamic balance dysfunction were recruited from the hospital databases and randomly allocated to the experimental or control group. The experimental group received 16 sessions of sensorimotor training based on the Feldenkrais method. Both groups received diabetic foot care instructions. The results were measured at the 3 and 6-month follow-up periods.

RESULTS

The mean age was 70 ± 8. A total of 44 participants were enrolled in the study, and 27 completed the process. No adverse events were reported. After the intervention, significant somatosensory results were obtained (p < 0.001). The results of the Up and Go and POMA tests were significant after the intervention (p < 0.001) and during the 3-month follow-up period for POMA (p = 0.018). The fear of falling showed significant results at the 3-month follow-up period (p = 0.03), and the quality of life in all measurements.

CONCLUSIONS

Significant short-term effects were obtained on somatosensory postural control-related function, dynamic balance, and fear of falling. Significant short and mid-term effects were achieved on quality of life. Older adults with diabetic polyneuropathy, dynamic balance impairment, or a history of falls can improve their abilities through the Feldenkrais method.

Effectiveness of Dyadic Advance Care Planning: A Systematic Review and Meta-Analysis

CONTEXT

Making decisions regarding end-of-life care is particularly challenging for patients and their family caregivers. Studies have advocated that family involvement in advance care planning is important to provide goal-concordant care and to increase family caregivers' preparation for surrogate decision-making. However, there is a lack of evidence to examine the effectiveness of advance care planning using the patient-caregiver dyadic approach.

OBJECTIVES

To evaluate the effectiveness of dyadic advance care planning.

METHODS

A literature search was systematically carried out in 7 databases from inception to March 2023. All randomized controlled trials with advance care planning interventions for mentally competent adults and their family caregivers were included. Meta-analysis was conducted for available quantitative data related to end-of-life care; Otherwise, narrative syntheses were performed.

RESULTS

In total, 14 randomized controlled trials were included. The main contents of all interventions were summarized into five categories, namely sharing illness experience and perception, introducing knowledge about advance care planning and end-of-life care, discussing individual's/dyads' values, goals, and care preferences, addressing dyads' discordance, and providing supports to complete advance care planning behaviors. The meta-analysis showed that dyadic advance care planning had significant effects on advance directive documentation (OR = 7.58, 95% CI [1.41, 40.63], P = 0.02) and proactive communication with doctors (OR = 2.42, 95% CI [1.42, 4.12], P = 0.001). In addition, interventions may improve dyad's congruence on end-of-life care, family caregivers' confidence in surrogate decision-making, and quality of end-of-life communication.

CONCLUSIONS

This review supports that dyadic advance care planning is a promising approach to preparing patients and their family caregivers for end-of-life communication and decision-making. Given that this multifaceted process is influenced by multiple factors within the socio-cultural context, future studies are warranted to identify the barriers and facilitators to implement dyadic advance care planning in real-world settings.

Prevention at home in older persons with (pre-)frailty: analysis of participants' recruitment and characteristics of the randomized controlled PromeTheus trial

BACKGROUND

The "PromeTheus" trial is evaluating a home-based, multifactorial, interdisciplinary prevention program for community-dwelling (pre-)frail older adults. These individuals often suffer from reduced participation, which can complicate the recruitment and enrollment in a clinical trial.

AIMS

The aim of this study was to evaluate different recruitment strategies and differences in participant characteristics in relation to these strategies.

METHODS

This cross-sectional study used baseline data from the randomized-controlled PromeTheus trial, in which community-dwelling (pre-)frail older persons (Clinical Frailty Scale [CFS] 4-6 pt., ≥ 70 years) were recruited via general practitioners ("GP recruitment") or flyers, newspaper articles, and personalized letters ("direct recruitment"). Differences in the sociodemographic, clinical, physical, functional, mobility-related, psychological and social characteristics were analyzed in relation to the recruitment strategy.

RESULTS

A total of 385 participants (mean age = 81.2, SD 5.9 years; women: n = 283, 73.5%) were enrolled, of which 60 (16%) were recruited by GPs and 325 (84%) through direct recruitment. Participants recruited via GPs had significantly higher subjective frailty levels (CFS), were more often physically frail (Fried Frailty Phenotype), and showed lower physical capacity (Short Physical Performance Battery), participation (disability component of the short version of the Late-Life Function and Disability Instrument), and life-space mobility (Life-Space Assessment) compared to those recruited via the direct approach (p = 0.002-0.026). Costs per randomized participant were 94€ for the GP recruitment strategy and €213 for the direct recruitment strategy.

CONCLUSION

Different strategies may be required to successfully recruit (pre-)frail home-living older adults into preventive programs. Direct recruitment strategies, in which potential participants are directly informed about the prevention program, seem to be more promising than GP recruitment but may result in enrolment of persons with less functional impairment and higher recruitment costs.

A qualitative exploration of challenges recruiting older adults for Being Your Best, a co-designed holistic intervention to manage and reduce frailty: lessons learnt amidst the COVID-19 pandemic in Melbourne, Australia

OBJECTIVES

Researchers face numerous challenges when recruiting participants for health and social care research. This study reports on the challenges faced recruiting older adults for Being Your Best, a co-designed holistic intervention to manage and reduce frailty, and highlights lessons learnt amidst the COVID-19 pandemic.

DESIGN

A qualitative study design was used. Referrer interviews were conducted to explore the recruitment challenges faced by the frontline workers. An audit of the research participant (aged ≥65) database was also undertaken to evaluate the reasons for refusal to participate and withdrawal from the study.

SETTING

Hospital emergency departments (EDs) and a home care provider in Melbourne, Australia.

PARTICIPANTS

Frontline workers and older adults.

RESULTS

From May 2022 to June 2023, 71 referrals were received. Of those referrals, only 13 (18.3%) agreed to participate. Three participants withdrew immediately after baseline data collection, and the remaining 10 continued to participate in the programme. Reasons for older adult non-participation were (1) health issues (25.3%), (2) ineligibility (18.3%), (3) lack of interest (15.5%), (4) perceptions of being 'too old' (11.2%) and (5) perceptions of being too busy (5.6%). Of those participating, five were female and five were male. Eleven referrer interviews were conducted to explore challenges with recruitment, and three themes were generated after thematic analysis: (1) challenges arising from the COVID-19 pandemic, (2) characteristics of the programme and (3) health of older adults.

CONCLUSION

Despite using multiple strategies, recruitment was much lower than anticipated. The ED staff were at capacity associated with pandemic-related activities. While EDs are important sources of participants for research, they were not suitable recruitment sites at the time of this study, due to COVID-19-related challenges. Programme screening characteristics and researchers' inability to develop rapport with potential participants also contributed to low recruitment numbers.

Strategies for increasing accrual in cancer clinical trials: What is the evidence?

INTRODUCTION

Despite the importance of clinical trial participation among cancer patients, few participate-and even fewer patients from ethnic and racial minoritized groups. It is unclear whether suggested approaches to increase accrual are successful. We conducted a scoping review to identify evidence-based approaches to increase participation in cancer treatment clinical trials that demonstrated clear increases in accrual. Notably, more stringent than other published reviews, only those studies with comparison data to measure a difference in accrual rates were included.

METHODS

We searched PubMed/MEDLINE, Embase, CINAHL, and Web of Science for English-language articles published from January 1, 2012, to August 8, 2022. Studies were included if they were conducted in the United States, described single or multicomponent interventions, and provided data to measure accrual relative to baseline levels or that compared accrual rates with other interventions.

RESULTS

Sixteen articles were included: six with interventions addressing patient barriers, two addressing provider barriers, seven describing institutional change, and one describing policy change. Key themes emerged, such as a focus on patient education, cultural competency, and building the capacity of clinics. Few studies provide comparative accrual data, making it difficult to identify with certainty any effective, evidence-based approaches for increasing accrual. Some patient- and system-level interventions studies showed modest increases in accrual primarily through pre-post measurement.

CONCLUSION

Despite an extensive body of literature about the barriers that impede cancer treatment trial accrual, along with numerous recommendations for how to overcome these barriers, results reveal surprisingly little evidence published in the last 10 years on interventions that increase accrual relative to baseline levels or compared with other interventions. As clinical trials are a primary vehicle through which we improve cancer care, it is critical that evidence-based approaches are used to inform all efforts to increase accrual. Strategies for increasing participation in cancer clinical trials must be developed and rigorously evaluated so that these strategies can be disseminated, participation in trials can increase and become more equitable, and trial results can become more generalizable.

How representative are participants in geriatric oncology clinical trials? The case of the 5C RCT in geriatric oncology: A cross-sectional comparison to a geriatric oncology clinic

INTRODUCTION

Frail older adults make up a substantial portion of the older adult population. However, frail patients are often excluded from randomized controlled trials. This underrepresentation restricts the extent to which trial findings can be generalized to this population. We compared a sample from the Canadian 5C Randomized Controlled Trial investigating comprehensive geriatric assessment (CGA) in the geriatric oncology setting in terms of frailty to patients referred to the Older Adults with Cancer Clinic (OACC) to determine if the trial sample was representative of the normal geriatric oncology practice.

MATERIALS AND METHODS

Baseline CGA data of 5C Trial participants seen at the Princess Margaret Cancer Centre (PM), were compared to data from OACC patients that were seen during the duration of the 5C trial (between April 2018 and April 2020) and that satisfied the 5C inclusion criteria. To assess the frailty of samples, sex, age, disease site, comorbidity level, medical optimization, social supports, functional status, falls risk, nutrition, cognition, and mood were compared between 5C participants and OACC patients using Fisher's exact and independent samples t-test.

RESULTS

A sample of 115 5C participants and 205 OACC patients were included. The mean age of 5C participants and OACC patients was 75.4 and 81.6 years, respectively (p < 0.001). The distribution of disease sites was significantly different between the samples (p < 0.001) and OACC patients were also significantly more impaired compared to 5C participants in comorbidity (23.4% versus 10.4% high comorbidity) (p = 0.001), IADL dependence (55.1% versus 42.6%) (p = 0.036), impaired physical function (70.6% versus 31.3%) (p < 0.001), falls risk (67.8% versus 27%) (p < 0.001), impaired nutrition (55.6% versus 40.9%) (p = 0.014), and cognition (47.2% versus 10%) (p < 0.001). There were no differences in sex, medication optimization, poor social supports, and impaired mood between the samples.

DISCUSSION

The 5C sample was less frail and younger than patients seen in the geriatric oncology clinic. Finding strategies to address barriers to the inclusion of frailer older adults is important to increase their representation in future trials to allow findings to be generalized to this vulnerable population.

Feasibility and clinical applicability of a novel power wheelchair training approach

PURPOSE

To evaluate the feasibility and the clinical applicability of administering the COMET (cognition, occupation, mobility, evaluation and training) intervention.

MATERIALS AND METHODS

A pilot research was conducted with adults who were being considered for power wheelchair (PWC) provision, or who were recently provided a PWC, and who had been identified to benefit from a PWC training. The COMET intervention applies a goal directed, client-centred and occupation-based approach. Feasibility and applicability indicators were collected for: process, resources, management and treatment. Indicators were evaluated as "successful/unsuccessful". Clinical outcomes included the Goal Attainment Scale (GAS), the Canadian Occupational Performance Measure (COPM), the Power mobility Indoor Driving Assessment (PIDA) and the Wheelchair Skills Test (WST).

RESULTS

Four females (62.5 ± 3.5 years) with cognitive impairment participated in the study. Among the 13 indicators, 10 were successfully achieved. Indicators that did not meet the criteria for success were adherence rate, safety and treatment for the PIDA. Two adverse events were reported, with one minor injury. Participants demonstrated better than expected results on the GAS, the COPM scores and the WST. However, only two reported an improvement beyond 4% of the PIDA.

CONCLUSIONS

With few modifications, the COMET intervention and the study protocol will be feasible and applicable in clinical practice. Individuals with complex cognitive and mobility impairment demonstrated abilities to learn PWC use. Further investigation of the COMET intervention is required to evaluate its efficacy.Implications for rehabilitationA novel power wheelchair (PWC) training approach adapted to individual with complex mobility and cognitive impairments was developed: the COMET (cognition, occupation, mobility, evaluation and training) intervention.The COMET intervention applies a goal directed, client-centred and occupation-based approach.With minor modifications, the COMET intervention may be feasible and clinically applicable to train individuals with complex motor and cognitive impairments how to use a PWC.Further evaluation of the COMET intervention and lager control trialsare suggested.

The feasibility of an exercise intervention after robotic-assisted radical cystectomy for urinary bladder cancer, prior to the CanMoRe trial

BACKGROUND

Complications after radical cystectomy for urinary bladder cancer are common. Physical activity after surgery is thought to reduce complications. However, patients with urinary bladder cancer have low levels of physical activity, and interventions supporting physical exercise are needed. This study aimed to evaluate the feasibility of a physical exercise intervention in primary health care. One of the aims of the larger clinical trial will be to reduce complications.

METHODS

Patients with urinary bladder cancer and who were scheduled for a robotic-assisted radical cystectomy were recruited from Karolinska University Hospital, between February and May 2019. The patients had to be mobile, understand Swedish, and live in Stockholm. The exercise programme was conducted at one primary health care setting over 12 weeks. The exercise programme included supervised aerobic and strengthening exercises, which were performed twice a week, as well as daily walks. Feasibility was measured with process feasibility, including eligibility criteria, adherence, and acceptability, and scientific feasibility, including the ability of outcomes to indicate change, safety, and progression in the exercise programme.

RESULTS

Ten patients with a median age of 70 years (min 53-max 86) were included. Adherence to all parts of the intervention was not feasible because of patients' postoperative complications, resulting in dropouts. For the patients who took part in the exercise programme, adherence and acceptability for the exercise period were feasible, but the 6-min walk test was not feasible at discharge from the hospital. Physiotherapists in the primary health care setting perceived the process as feasible. Moreover, the ability of outcomes to indicate change and progression in the exercise programme was feasible, meanwhile no adverse events were registered.

CONCLUSIONS

The exercise intervention was feasible for the patients that took part in the exercise programme, with respect to safety and progression through the exercise programme. Furthermore, this study suggests that some improvements needed to be implemented in the process, prior to the upcoming randomised controlled trial.

Better Before-Better After: A Qualitative Phenomenology Study of Older Adults' Experiences With Prehabilitation Before Total Hip Replacement

Total hip replacement is considered a successful intervention for pain relief and improved function. However, poor presurgery physical function may increase the likelihood of delayed postsurgery recovery. The purpose of this study was to describe community-dwelling older adults' experiences with a prehabilitation program (preoperative exercise) before total hip replacement. Four participants were interviewed 13 and 15 weeks postsurgery. The interviews were recorded, transcribed, and analyzed with systematic text condensation. Physical, mental, and social limitations were, to a higher or lesser degree, part of the participants' life presurgery. The results indicate that tailored close supervised training presurgery increased the participants' amount of and adherence to exercise, confidence, and sense of control. The participants had a positive experience of increased strength during the training period and gained motivation to perform progressive training. The exercise program helped the participants be physically and mentally prepared. The results indicate that close supervised prehabilitation in community-dwelling older adults undergoing total hip replacement can contribute to improved function and increase the level of activity and self-efficacy postsurgery.

A Physiotherapy-Led Transition to Home Intervention for Older Adults Following Emergency Department Discharge: A Pilot Feasibility Randomised Controlled Trial (ED PLUS)

Background

Older adults frequently attend the emergency department (ED) and experience high rates of subsequent adverse outcomes including functional decline, ED re-presentation and unplanned hospital admission. The development of effective interventions to prevent such outcomes is a key priority for research and service provision. Our aim was to evaluate the feasibility of a physiotherapy-led integrated care intervention for older adults discharged from the ED (ED PLUS).

Patients and Methods

Older adults presenting to the ED of a university teaching hospital with undifferentiated medical complaints and discharged within 72 hours were computer randomised in a ratio of 1:1:1 to deliver usual care, Comprehensive Geriatric Assessment (CGA) in the ED, or ED PLUS. ED PLUS is an evidence-based and stakeholder-informed intervention to bridge the care transition between the ED and community by initiating a CGA in the ED and implementing a six-week, multi-component, self-management programme in the patient's home. Feasibility and acceptability were assessed quantitatively and qualitatively. All clinical and process outcomes were assessed by a research nurse blinded to group allocation. Data analyses were primarily descriptive.

Results

Twenty-nine participants were recruited indicating a 67% recruitment rate. At 6 months, there was 100% retention in the usual care group, 88% in the CGA group and 90% in the ED PLUS group. ED PLUS participants expressed positive feedback, and there was a trend towards improved function and quality of life and less ED revisits and unscheduled hospitalisations in the ED PLUS group.

Conclusion

ED PLUS bridges the transition of care between the index visit to the ED and the community and is feasible using systematic recruitment strategies. Despite recruitment challenges in the context of COVID-19, the intervention was successfully delivered and well received by participants. There was a lower incidence of functional decline and improved quality of life in the ED PLUS group.

Trial Registration

The trial was registered in Clinical Trials Protocols and Results System as of 21st July 2021, with registration number NCT04983602.

Nutrition Education Improves Intakes of Protein, Polyunsaturated Fatty Acids, and Vitamins C and E in Community-Dwelling Older Adults

This study investigated the effect of nutrition education program on protein and nutrient intake, physical performance, and health-related quality of life (HRQoL) in community-dwelling older adults (≥65 years). The participants were randomized in clusters to intervention (IG, n = 51) and control (CG, n = 45) groups. Those in IG took part in the Eating for Strong Aging education program consisting of nutrition education in peer groups, written materials, and personal advice. Nutrient intake was assessed with 3-day food diaries, physical performance with Short Physical Performance Battery (SPPB) and HRQoL with 15-D-QoL instrument. Total of 89 participants completed the study. The mean age was 76 years (IG) and 74 years (CG). At three months, the mean change in protein intake was 0.10 g/adjusted bodyweight (ABW) kg/d in the IG, and -0.07 g/ABW kg/d in the CG (p = 0.024). Intakes of polyunsaturated fatty acids and vitamins C and E increased in the IG compared to the CG (p < 0.05). Changes in SPPB or total HRQoL scores between the IG and the CG did not differ. HRQoL dimension mobility improved in the IG compared to the CG (p = 0.035). In conclusion, the Eating for Strong Aging educational program improved nutrition and may be beneficial for mobility-related QoL.

Including older people in health and social care research: best practice recommendations based on the INCLUDE framework

BACKGROUND

Older people are often explicitly or implicitly excluded from research, in particular clinical trials. This means that study findings may not be applicable to them, or that older people may not be offered treatments due to an absence of evidence.

AIMS

The aim of this work was to develop recommendations to guide all research relevant to older people.

METHODS

A diverse stakeholder group identified barriers and solutions to including older people in research. In parallel, a rapid literature review of published papers was undertaken to identify existing papers on the inclusion of older people in research. The findings were synthesised and mapped onto a socio-ecological model. From the synthesis we identified themes that were developed into initial recommendations that were iteratively refined with the stakeholder group.

RESULTS

A range of individual, interpersonal, organisational, community and policy factors impact on the inclusion of older people in research. A total of 14 recommendations were developed such as removing upper age limits and comorbidity exclusions, involving older people, advocates and health and social care professionals with expertise in ageing in designing the research, and considering flexible or alternative approaches to data collection to maximise opportunities for participation. We also developed four questions that may guide those developing, reviewing and funding research that is inclusive of older people.

CONCLUSION

Our recommendations provide up to date, practical advice on ways to improve the inclusion of older people in health and care research.

Feasibility of a 12-Month Follow-Up in Swiss Older Adults after Post-Acute Care in Nursing Homes-A Pilot Study

(1) Background: Post-acute care (PAC) aims to support functional recovery in older adults after acute hospitalization in order to regain a sufficient level of self-care facilitating their return home. However, the long-term outcomes of PAC are understudied due to challenges in recording a follow-up. We aimed to investigate the feasibility of a 12-month follow-up after PAC in Swiss nursing homes, examining practicability and potential factors influencing participation rate. (2) Methods: Collection of one-year follow-up data among 140 eligible patients after PAC in nursing homes was attempted. Patients were recruited using letters and phone calls between August and December 2017. We compared baseline data of all initial PAC patients with those who declined participation in the follow-up to identify factors potentially influencing participation. (3) Results: Overall mortality at 12 months was 25% (n = 35 of 140). Of the 105 survivors, 53 (50%) refused participation, 26 (25%) were interviewed, and 26 (25%) were lost to follow-up. Comparison of baseline characteristics between participants and objectors indicated significant statistical differences in Mini-Mental State Examination (MMSE) scores (participants mean of 26.0 [SD 3.92] vs. objectors mean of 23.5 points [SD 4.40], p = 0.015). Further, logistic regression showed statistically significantly greater odds of participation (OR 1.25 [95% CI 1.06-1.48]) for each point increase in MMSE scores. (4) Conclusions: Long-term follow-up studies in older adults after PAC are challenging due to high mortality and dropout rates. Of note, intact cognitive function at baseline was associated with a higher willingness to participate in a follow-up phone interview. The assessment of cognitive function should be considered when estimating the participation rate in older patients.

Older patients' perspectives on participating in multimodal rehabilitation including anabolic steroids following hip fracture: a qualitative study embedded within a pilot RCT

PURPOSE

To explore patient perspectives of participating in a pilot RCT evaluating feasibility and effect of anabolic steroid, physiotherapy and nutritional supplement following hip fracture.

METHODS

Semi-structured telephone-based interviews of 16 women and three men (average age 73 years) were conducted at baseline and after a 12-week intervention. Qualitative content analysis was performed.

RESULTS

Two main categories were identified: (1) Trust and hope for a positive change with three sub-categories; reflections on anabolic steroids, anticipation of extra attention, lack of energy. (2) Curiosity, care, and commitment with four sub-categories; a sense of anabolic steroids, feeling of exclusivity and privileges, challenges and sense of obligation, and perspectives on personal gain.

CONCLUSIONS

Findings suggest high acceptability of the intervention. Participants motivated their participation on a trust that the intervention would "do more good than harm". They found the randomization and possibility of receiving anabolic steroids intriguing, and especially valued trial participation because of their experience of getting extra care and "deluxe" rehabilitation including close contact and support by health professionals. Our findings may help inform future research recruiting older patients and generally considered relevant for health professionals in rehabilitation, emphasizing the impact of professional guidance and social support to encourage self-efficacy.Implications for rehabilitationWith muscle enhancing medicine being suggested as a supplement in rehabilitation following hip fracture, exploring patients' perspectives is warranted and may help inform future trials in this area.Factors reported as important by older adults for engaging in rehabilitation trials are: simple but thorough information, friendly and trustful relation with study staff and opportunities of extra care and attention.Older patients with hip fracture highly valued professional guidance and support by health professionals during the rehabilitation intervention. High acceptability was identified for the supervised outpatient rehabilitation, where especially the individually structured progressive strength training was highlighted as the "active ingredient" accelerating recovery and potentially promoted self-efficacy.

Conceptualization of frailty in rehabilitation interventions with adults: a scoping review

Purpose: We aimed to synthesize the literature that considered frailty in the evaluation of rehabilitation interventions for adults (aged ≥18) by answering: (1) how is frailty defined in rehabilitation intervention research?; (2) how is frailty operationalized in rehabilitation intervention research?; (3) what are the characteristics of rehabilitation interventions for frail adults and what frailty related outcomes are assessed?Materials and methods: A scoping review was conducted. Data were analyzed using descriptive statistics and qualitative content analysis.Results: 53 articles met the inclusion criteria. Most studies were conducted in Europe and involved randomized control trials. The included studies reported on rehabilitation interventions that only included individuals aged 50 or older. Thirteen studies used Fried's definition of frailty, but most (n = 27) did not use any definition. Many studies did not differentiate between the conceptualization (e.g., definition) and operationalization (e.g., use of inclusion/exclusion criteria, outcome measures) of frailty. Most interventions focused on exercise. Instrumental activities of daily living reported most frequently as outcomes (n = 11).Conclusions: There is an absence of consistent definitions of frailty in rehabilitation interventions and current definitions tend to focus on physical functioning. The authors suggest rehabilitation researchers consider an expanded definition of frailty informed by the International Classification of Functioning, Disability and Health framework.IMPLICATIONS FOR REHABILITATIONRehabilitation professionals should use an expanded definition of frailty, informed by the International Classification of Functioning, Disability and Health framework, should include physical, mental, personal, environmental, and social factors to decrease, delay, or prevent frailty in adults.Rehabilitation professionals should consider a broader operationalization of frailty that is not dependent on age and physical functioning.Rehabilitation professionals that consider a broader conceptualization of frailty should tailor interventions to the specific needs of frail adults.

The challenge of recruiting multimorbid older patients identified in a hospital database to a randomised controlled trial

BACKGROUND

Research involving multimorbid older patients is gaining momentum. However, little is known about how to plan a randomised controlled trial (RCT) involving this group of patients. An evidence-based approach to the challenges of a recruitment process could guide researchers and help prevent underpowered trials.

AIM

To define the number of multimorbid older patients that need to be identified and the number of eligible patients that need to be invited to achieve the desired recruitment number to a RCT.

METHOD

We used recruitment data from the GerMoT trial, a RCT comparing proactive outpatient care based on Comprehensive Geriatric Assessment with usual care. Multimorbid older patients with high healthcare utilisation were recruited to the trial.

RESULTS

Of the 1212 patients identified in a database as meeting the inclusion criteria 838 (70%) could be invited to participate in the trial. The rest could not be invited for a variety of reasons; 162 had moved out of area or into nursing homes and 86 had died before they could be contacted. 113 could not be reached. 450 (54%) of the invited patients agreed to participate.

CONCLUSIONS

In our study, we have shown that it is possible to achieve a good consent rate despite older participants with multimorbidity. This can be used when planning an RCT for this patient group, who are often excluded from clinical trials. Our results are specific to a context that provides similar abilities to identify and recruit patients as can be seen in Sweden.

A walking programme for adults living in the community after hip fracture: A feasibility randomized controlled trial

OBJECTIVE

To test the feasibility of a walking programme for community-dwelling adults recovering from hip fracture.

DESIGN

A randomized controlled trial with embedded qualitative analysis.

SETTING

Community.

PARTICIPANTS

Aged at least 60 years and living in the community after hip fracture.

INTERVENTIONS

In addition to standard care, the experimental group received weekly home-based physiotherapy for 12 weeks to facilitate 100 minutes/week of moderate-intensity walking.

MAIN OUTCOME MEASURES

Feasibility domains of demand, acceptability, implementation, practicality and limited efficacy.

RESULTS

Of 158 potentially eligible, 38 participated (23 women, mean age 80 years, SD 9). The recruitment rate of 24% indicated low demand. Participants considered the walking programme highly acceptable. The programme was implemented as intended; the experimental group received a mean of 11 (SD 1) consultations and averaged more than 100 min of walking per week. The programme was practical with no serious adverse events and no between-group difference in risk of falling or hospital readmissions. Demonstrating evidence of efficacy, there were moderate standardized mean differences for physical activity favouring the experimental group, who increased daily moderate-intensity physical activity compared to the control group (MD 8 min, 95% CI 2-13). There were no between-group differences in mobility, walking confidence or quality of life.

CONCLUSION

A walking programme for community-dwelling older adults after hip fracture was acceptable, could be implemented as intended and was practical and demonstrated preliminary evidence of efficacy in increasing physical activity. However, low demand would threaten the feasibility of such a programme.

Ethical Issues in Research: Perceptions of Researchers, Research Ethics Board Members and Research Ethics Experts

In the context of academic research, a diversity of ethical issues, conditioned by the different roles of members within these institutions, arise. Previous studies on this topic addressed mainly the perceptions of researchers. However, to our knowledge, no studies have explored the transversal ethical issues from a wider spectrum, including other members of academic institutions as the research ethics board (REB) members, and the research ethics experts. The present study used a descriptive phenomenological approach to document the ethical issues experienced by a heterogeneous group of Canadian researchers, REB members, and research ethics experts. Data collection involved socio-demographic questionnaires and individual semi-structured interviews. Following the triangulation of different perspectives (researchers, REB members and ethics experts), emerging ethical issues were synthesized in ten units of meaning: (1) research integrity, (2) conflicts of interest, (3) respect for research participants, (4) lack of supervision and power imbalances, (5) individualism and performance, (6) inadequate ethical guidance, (7) social injustices, (8) distributive injustices, (9) epistemic injustices, and (10) ethical distress. This study highlighted several problematic elements that can support the identification of future solutions to resolve transversal ethical issues in research that affect the heterogeneous members of the academic community.

Research engagement and experiences of patients pre- and post-implant of a left ventricular assist device from the mechanical circulatory support measures of adjustment and quality of life (MCS A-QOL) study

PURPOSE

Adults living with mechanical circulatory support (MCS) present with unique challenges (e.g., left ventricular assist device [LVAD]-related self-care, adverse events) to research study enrollment, engagement, and completion. The purpose of this study was to understand the experiences of adults with MCS who were eligible for and enrolled in a study of health-related quality of life (HRQOL).

METHODS

In a secondary analysis of data from the Mechanical Circulatory Support: Measures of Adjustment and Quality of Life study, we used a mixed-methods approach to evaluate research engagement and experiences among adults preparing to undergo or currently living with MCS implant. First, we assessed the cascade of study engagement. Second, we assessed research experiences using a structured interview developed for this study.

RESULTS

Of 1011 participants approached for the study, 86.7% enrolled, 12.7% declined, and 0.6% were ineligible. Of 877 participants enrolled, 272 were pre-implant (of whom 88% completed assessments; "respondents") and 605 were post-implant (of whom 74% completed assessments). Only 14% of respondents reported difficulty completing the questionnaires, 54% had previously used an iPad to complete questionnaires, and 62% reported that their experience was "as expected." Respondents qualitatively described both positive (e.g., value of research) and negative (e.g., too much time) research experiences, difficulties completing questionnaires (e.g., online platform, health literacy issues), and provided recommendations for the questionnaires and delivery.

CONCLUSIONS

Participants enjoyed participating in HRQOL research focused on MCS and had unique perspectives for improving the questionnaires. It is important to minimize the burden of participation and critical to be flexible to meet participant preferences for research engagement.

Feasibility and Safety of Whole-Body Electromyostimulation in Frail Older People—A Pilot Trial

Whole-body electromyostimulation (WB-EMS) induces high-intense stimuli to skeletal muscles with low strain on joints and the autonomic nervous system and may thus be suitable for frail, older people. However, if trained at very high intensities, WB-EMS may damage muscles and kidneys (rhabdomyolysis). This study aimed at investigating the feasibility, safety and preliminary efficacy of WB-EMS in frail, older people. Seven frail (81.3 ± 3.5 years), 11 robust (79.5 ± 3.6 years), 10 young (29.1 ± 6.4 years) participants completed an eight-week WB-EMS training (week 1–4: 1x/week; week 5–8: 1.5x/week) consisting of functional exercises addressing lower extremity strength and balance. Feasibility was assessed using recruitment, adherence, retention, and dropout rates. The satisfaction with WB-EMS was measured using the Physical Activity Enjoyment Scale for older adults (PACES-8). In week 1, 3, and 8 creatine kinase (CK) was assessed immediately before, 48 and 72 h after WB-EMS. Symptoms of rhabdomyolysis (muscle pain, muscle weakness, myoglobinuria) and adverse events were recorded. Functional capacity was assessed at baseline and after 8 weeks using the Short Physical Performance Battery (SPPB), Timed Up-and-Go Test (TUG), Choice Stepping Reaction Time Test (CSRT), 30-second Chair-Stand Test (30-STS), maximum isometric leg strength and handgrip strength. The recruitment rate of frail individuals was 46.2%, adherence 88.3% and the dropout rate 16.7%. All groups indicated a high satisfaction with WB-EMS. CK activity was more pronounced in young individuals with significant changes over time. Within older people CK increased borderline-significantly in the frail group from baseline to week 1 but not afterwards. In robust individuals CK increased significantly from baseline to week 1 and 3. No participant reached CK elevations close to the threshold of ≥5,000 U/l and no symptoms of rhabdomyolysis were observed. With the exception of the TUG (p = 0.173), frail individuals improved in all tests of functional capacity. Compared to the young and robust groups, frail individuals showed the greater improvements in the SPPB, handgrip strength, maximum isokinetic hip-/knee extension and flexion strength. WB-EMS is feasible for frail older people. There were no clinical signs of exertional rhabdomyolysis. WB-EMS proved to be sufficiently intense to induce meaningful changes in functional capacity with frail individuals showing greater improvements for several measures.

The Performance Assessment of Self-Care Skills to Predict Adverse Events Post-Discharge

Background. The Performance Assessment of Self-Care Skills (PASS) is a standardized assessment of the ability to perform daily activities. Purposes. This preliminary exploratory study aimed to 1) explore the ability of four PASS tasks to predict adverse events (readmissions and injuries) in older adults following hospitalization; 2) compare PASS's predictive validity to that of a generic tool (SMAF) and OT clinical judgement. Method.Twenty-two older patients were assessed in hospital at discharge and at home one week later. Adverse events were documented for six months post-discharge. Sensitivity and specificity analyses (ROC curves, Fisher's exact tests) were performed. Findings. Two PASS tasks (telephone, medication), the SMAF-Social and OT clinical judgement could identify individuals at risk of readmission (AUC > 0.7; p < 0.05). Implications. Using the PASS to assess more cognitively demanding tasks could be a promising way to predict adverse events after discharge, as a complement to clinical judgment.

Associations between physical activity levels and renal recovery following acute kidney injury stage 3: a feasibility study

BACKGROUND

Acute kidney injury (AKI) can lead to chronic kidney disease, which results in poor long-term outcomes. There is plausibility that increased levels of physical activity may promote renal recovery post-AKI. This study aimed to investigate associations between physical activity levels and renal recovery following stage 3 AKI, and to assess the feasibility of measuring physical activity levels in this population.

METHODS

Forty One hospitalised patients with AKI stage 3 were enrolled. Serum creatinine and estimated glomerular filtration rate (eGFR) were collected at 12 months prior to the development of AKI, during the hospital admission when the episode of AKI stage 3 occurred, and at 1-, 3- and 6-months post discharge. All participants completed the General Practice Activity Questionnaire (GPPAQ) to assess physical activity levels. A pedometer was also worn for 7 days immediately following discharge and at 6-months post discharge to ascertain an average daily step count. Feasibility outcomes including eligibility, recruitment and retention rates, and losses to follow up were also assessed.

RESULTS

The average (± SD) baseline eGFR and median (IQR) serum creatinine was 71 ± 20 mL/min/1.73m² and 85 (49) μmol/L respectively. A threefold increase in creatinine occurred during hospitalisation 436 (265) μmol/L. Greatest renal recovery occurred prior to discharge, with recovery continuing for a further three months. Inactive individuals (low GPPAQ scores) had consistently higher serum creatinine values compared to those who were active: 1 months 122 (111) μmol/L vs 70 (0) μmol/L, 6 months 112 (57) μmol/L vs 68 (0) μmol/L. Individuals with higher step counts also displayed better renal recovery 6-months post discharge (r = -0.600, p = 0.208).

CONCLUSIONS

Higher levels of physical activity are associated with improved renal recovery after 6- months following an episode of stage 3 AKI. A future randomised controlled trial is feasible and would be required to confirm these initial findings.

Evaluation of Recruitment Strategies for Home-Living Vulnerable Older Adults With Depression: Findings From a Randomized Controlled Psychotherapy Trial

OBJECTIVE

Vulnerable older adults, such as physically impaired or care-dependent individuals, are vastly underrepresented in psychotherapy research. Improving their inclusion in randomized controlled trials is necessary to determine the effectiveness of psychotherapy in this population. This study is the first to systematically evaluate strategies to recruit home-living vulnerable older adults with clinically significant depression into a large randomized controlled psychotherapy trial. Potential participants were approached directly (self-referral) or via cooperation with gatekeepers (gatekeeper-referral).

METHODS

Successful recruitment strategies and the person initiating the first contact with the study team were recorded. Recruitment strategies were compared with respect to the number of inquiries and inclusion rates, study personnel's time investment, and participant characteristics (sociodemographics, functional and cognitive status, depression and anxiety scores).

RESULTS

Most of the N = 197 participants were included via gatekeeper-referral (80.5%, 95% confidence interval = [74.9, 86.1]), but time investment for gatekeeper-referrals was five times higher than for self-referral by media reports. Clinical psychologists and medical practitioners referred the largest proportion of participants (32.3% each) and referral by medical practitioners led to highest inclusion rates (55.6%; χ²(3) = 8.964, p <0.05). Most participants were referred from a hospital setting (50.3%), whereas referral numbers by medical practices were low (15.9%). Participants who initiated the first contact themselves had higher inclusion rates and were less functionally impaired.

CONCLUSION

Including home-living vulnerable older adults into psychotherapy trials requires simultaneous implementation of diverse recruitment strategies. Medical practitioners and psychologists, especially in hospitals, are the most effective recruitment strategy, but self-referral via media is most cost-efficient in terms of time investment.

Challenges and Opportunities in Conducting Research with Older Adults with Dementia during COVID ‐19 and Beyond

The coronavirus disease 19 (COVID‐19) pandemic has created significant and new challenges for the conduct of clinical research involving older adults with Alzheimer's disease and related dementias (ADRD). It has also stimulated positive adaptations in methods for engaging older adults with ADRD in research, particularly through the increased availability of virtual platforms. In this paper, we describe how we adapted standard in‐person participant recruitment and qualitative data collection methods for virtual use in a study of decision‐making experiences in older adults with ADRD. We describe key considerations for the use of technology and virtual platforms and discuss our experience with using recommended strategies to recruit a diverse sample of older adults. We highlight the need for research funding that supports the community‐based organizations on which improving equity in ADRD research participation often depends.

Prioritization of indicators of the quality of care provided to older adults with frailty by key stakeholders from five canadian provinces

Background

To meet the needs of older adults with frailty better, it is essential to understand which aspects of care are important from their perspective. We therefore sought to assess the importance of a set of quality indicators (QI) for monitoring outcomes in this population.

Methods

In this mixed-method study, key stakeholders completed a survey on the importance of 36 QIs, and then explained their ratings in a semi-structured interview. Stakeholders included older adults with frailty and their caregivers, healthcare providers (HCPs), and healthcare administrators or policy/decision makers (DMs). We conducted descriptive statistical analyses of quantitative variables, and deductive thematic qualitative analyses of interview transcripts.

Results

The 42 participants (8 older adults, 18 HCPs, and 16 DMs) rated six QIs as more important: increasing the patients’ quality of life; increasing healthcare staff skills; decreasing patients’ symptoms; decreasing family caregiver burden; increasing patients’ satisfaction with care; and increasing family doctor continuity of care.

Conclusions

Key stakeholders prioritized QIs that focus on outcomes targeted to patients and caregivers, whereas the current healthcare systems generally focus on processes of care. Quality improvement initiatives should therefore take better account of aspects of care that are important for older adults with frailty, such as having a chance to express their individual goals of care, receiving quality communications from HCPs, or monitoring symptoms that they might not spontaneously describe. Our results point to the need for patient-centred care that is oriented toward quality of life for older adults with frailty.

Effectiveness of a community-based integrated service model for older adults living alone: A nonrandomized prospective study

OBJECTIVE

Older adults living alone face physical, emotional, and social health problems, and prefer to age in place (AIP) in their homes. A community-based integrated model for AIP is needed and few studies have identified its impact on older adults living alone.

METHODS

This was a non-randomized prospective study. Participants were 877 community-dwelling older adults living alone, aged above 65 years, in S* city in South Korea. The intervention group (n = 331) received a community-based integrated service (CBIS) model based on AIP for six months from October 2019 to April 2020.

RESULTS

Scores on frailty (β = -0.377, p < .001), loneliness (β = -1.897, p = .018), and health-related quality of life (β = 4.299, p = .021) significantly improved in the intervention group. Among the intervention group, loneliness scores significantly improved among participants aged under 80 years than those aged over 80 years.

CONCLUSION

The CBIS model improved frailty, loneliness, and quality of life in community-dwelling older adults living alone.

Public attitudes to the use of remote data collection in clinical research

Background/aims

Coronavirus Disease 2019 (COVID-19) has presented an unprecedented challenge for delivering clinical research. The use of technology-assisted data collection for clinical research is desirable for many practitioners, but the acceptability of use in the general population has not been assessed. The aim of the study was to assess attitudes towards using technology-assisted remote methods in the delivery of clinical research in the UK and to understand the barriers to taking part in research with respect to both remote assessments and traditional research methods across different age ranges.

Methods

The study was conducted as an online anonymous survey with a 4-part questionnaire, between August 2020 and December 2020. Participants living in the UK aged 18 years and above were eligible to take part.

Results

A total 351 completed the survey and are included in the data analysis. In all age groups, participants identified that use of online assignments, video calls and telephone calls would make them more likely to take part in clinical research. Overall, the largest barrier to taking part in research was time commitments and timing of the appointment. COVID-19 has had a small, positive influence on the confidence of using technology in the general population.

Conclusions

The study found that there is a large interest in taking part in research using online, telephone and video call appointments, which could facilitate research delivery in light of ongoing COVID-19-related restrictions and also improve the accessibility and inclusivity of research.

A Randomized Controlled Feasibility Trial Evaluating a Resistance Training Intervention With Frail Older Adults in Residential Care: The Keeping Active in Residential Elderly Trial

Frailty is associated with negative health outcomes, disability, and mortality. Physical activity is an effective intervention to improve functional health status. However, the effect of resistance training on multidimensional health in frail older adults remains unclear. This randomized controlled trial was conducted in a U.K. residential care home to assess feasibility with limited efficacy testing on health and functional outcomes and to inform a future definitive randomized controlled trial. Eleven frail older adults (>65 years) completed a 6-week machine-based resistance training protocol three times a week. Uptake and retention were greater than 80%. The measures and intervention were found to be acceptable and practicable. The analyses indicated large improvements in functional capacity, frailty, and strength in the intervention group compared with the controls. These findings support the feasibility of a definitive randomized controlled trial and reinforce the value of resistance training in this population. This trial was registered with ClinicalTrials.gov: NCT03141879.

Simultaneous cognitive-physical dual task training based on fairy tales in older adults with mild cognitive impairment: A pilot study

In this study, we aimed to develop a simultaneous cognitive-physical dual-task training program based on familiar cultural backgrounds using fairy tales and to explore its feasibility and preliminary effects, including effects on neurophysiological, cognitive, and physical functions. A single-group pretest-posttest design (n = 9) was employed to evaluate the effects of the cognitive-physical intervention performed for 60-90 min once a week for 12 weeks. The findings showed that perceived memory and physical self-efficacy, muscle strength, and cognitive function were significantly increased after the intervention. Although the relative beta band power measured using electroencephalography showed a tendency to increase in eight brain domains after the 12-week intervention, the changes were not significant. Findings suggested that the intervention was feasible and provided beneficial effects on cognitive and physical functions in older adults with mild cognitive impairment. Future research on larger sample sizes using randomized controlled trials is needed to determine the effectiveness of such interventions on neurophysiological functions.

Randomised trial of a serious illness decision aid (Plan Well Guide) for patients and their substitute decision-makers to improve engagement in advance care planning

OBJECTIVE

To evaluate the feasibility and efficacy of a serious illness decision aid (Plan Well Guide) in increasing the engagement of substitute decision-makers (SDM) in advance care planning (ACP).

METHODS

This trial was conducted (2017-2019) in outpatient settings in Ontario, Canada, aiming to recruit 90 dyads of patients aged 65 years and older at high risk of needing future medical decisions and their SDM. Participants were randomised to receive the intervention immediately or to a 3-month wait period. The Plan Well Guide was administered to the patient and SDM by a facilitator. Outcomes were change on the validated 17-item SDM ACP Engagement Survey (primary) and 15-item patient ACP Engagement Survey (secondary).

RESULTS

Of 136 dyads approached, 58 consented and were randomised and 45 completed the study (28 immediate intervention, 17 delayed intervention). The trial was stopped early because of difficulties with enrolling and following up participants. The mean changes on the SDM ACP Engagement Survey and the patient ACP Engagement Survey favoured the first group but were not statistically significant (mean difference (MD)=+0.2 (95% CI: -0.3 to 0.6) and MD=+0.4 (95% CI: -0.1 to 0.8), respectively). In a post-hoc subgroup analysis, significant treatment effects were seen in SDMs with a lower-than-median baseline score compared with those at or above the median.

CONCLUSIONS

In this statistically underpowered randomised trial, differences in SDM ACP engagement between groups were small. Further information is needed to overcome recruitment challenges and to identify people most likely to benefit from the Plan Well Guide.Trial registration number NCT03239639.

Development of a multi-component intervention to promote participation of Black and Latinx individuals in biomedical research

INTRODUCTION

Barriers to research participation by racial and ethnic minority group members are multi-factorial, stem from historical social injustices and occur at participant, research team, and research process levels. The informed consent procedure is a key component of the research process and represents an opportunity to address these barriers. This manuscript describes the development of the Strengthening Translational Research in Diverse Enrollment (STRIDE) intervention, which aims to improve research participation by individuals from underrepresented groups.

METHODS

We used a community-engaged approach to develop an integrated, culturally, and literacy-sensitive, multi-component intervention that addresses barriers to research participation during the informed consent process. This approach involved having Community Investigators participate in intervention development activities and using community engagement studios and other methods to get feedback from community members on intervention components.

RESULTS

The STRIDE intervention has three components: a simulation-based training program directed toward clinical study research assistants that emphasizes cultural competency and communication skills for assisting in the informed consent process, an electronic consent (eConsent) framework designed to improve health-related research material comprehension and relevance, and a "storytelling" intervention in which prior research participants from diverse backgrounds share their experiences delivered via video vignettes during the consent process.

CONCLUSIONS

The community engaged development approach resulted in a multi-component intervention that addresses known barriers to research participation and can be integrated into the consent process of research studies. Results of an ongoing study will determine its effectiveness at increasing diversity among research participants.

Recruiting Low-Income African American Men in Mental Health Research: A Community-Based Participatory Research Feasibility Study

African Americans (AAs) are 20% more likely to develop serious psychological distress compared to Whites but are less likely to use mental health services. The study objective was to evaluate the effectiveness of recruitment strategies to engage AA fathers in a mental health intervention.

Using the community-based participatory research (CBPR) approach, a community-academic partnership (CAP) developed and implemented direct and indirect referral strategies to engage AA fathers in a mental health intervention. Direct referral strategies focused on community partner identification of potentially eligible participants, providing information about the study (i.e., study flyer), and referring potential participants to the study. Indirect referrals included posting flyers in local businesses frequented by AA men, radio advertisements, and social media posts from community organizations.

From January to October 2019, 50 direct and 1388 indirect referrals were documented, yielding 24 participants screened and 15 enrolled. Of all participants screened, 58% were referred through indirect referral, 38% were referred directly by community partners, and 4% of the participants were referred through both direct and indirect referrals. Twenty percent of those exposed to the direct referral methods and 1% of those exposed to the indirect referral methods were enrolled. The indirect referrals accounted for 60% of enrollment, whereas the direct referrals accounted for 33.3% of enrollment.

Collaborating with the community partners to engage hard-to-reach populations in mental health studies allowed for broad dissemination of recruitment methods, but still resulted in low participant accrual. Additional focus on increasing direct referral methods appears to be a fruitful area of CBPR.

Methods for evaluating the benefit and harms of deprescribing in observational research using routinely collected data

Deprescribing is defined as "the planned and supervised process of dose reduction or stopping of medication that might be causing harm, or no longer be of benefit". Barriers to deprescribing include healthcare professional fear and lack of guidance. These may stem from limited available evidence on benefits and harms of deprescribing medications commonly used among older persons. Advances in pharmacoepidemiology and causal inference methods to evaluate comparative effectiveness and safety of prescribing medications have yet to be considered for deprescribing medication. This paper discusses select methods and how they can be applied to deprescribing research, using case studies of benzodiazepines and low-dose acetylsalicylic acid (aspirin). Target trial emulation involves the explicit application of design principles from randomised controlled trials to observational studies. Several design aspects, including defining eligibility criteria and time zero, require additional considerations for deprescribing studies. The active comparator new user design also presents challenges, including selection of an appropriate comparator. This paper discusses these aspects, and others, in relation to deprescribing studies. Furthermore, methods proposed to control for confounding, in particular, the prior event rate ratio and propensity scores, are discussed. Introduction of billing codes or mechanisms for accurately determining when deprescribing has occurred would enhance the ability to conduct research using routinely collected data. Although the approaches discussed in this paper may strengthen observational studies of deprescribing, their use may be best suited to certain scenarios or research questions, where randomised controlled trials may be less feasible.

Evaluating Nursing Home Resident and Staff Experiences With a Life Story Program

Life story programs hold promise for improving person-centered care and relationships between nursing home residents and staff. A pilot life story intervention study in 16 nursing homes provided residents with complimentary biographical life story books and summaries, and staff with action plans to enhance care planning. Trained volunteers and program staff collected life stories, and researchers interviewed 170 residents at three points in time. Overall, residents had positive experiences with the program, but were less willing to share their books with others afterwards. They also experienced a decrease in depression (Patient Health Questionnaire-8 [PHQ-8]) over time. Surveys of 92 staff demonstrated increases over time in perceived importance of knowing residents' life stories. Administrator/admissions staff found it conditionally feasible to incorporate the program into admission processes. Practice implications of life story work include opportunities to help staff learn more about residents they care for, improve person-centered care, and honor resident preferences in care planning.

Energy and protein intake in medical and geriatric inpatients with MEDPass versus conventional administration of oral nutritional supplements: study protocol for the randomized controlled MEDPass Trial

Background

Disease-related malnutrition is highly prevalent in hospitalized medical and geriatric inpatients. It is associated with negative outcomes such as muscle wasting, decline of functional status, and increased morbidity and mortality. Oral nutritional supplements (ONS) are frequently used in nutritional therapy to increase intake. However, compliance to ONS is often limited and maybe improved by prescribing ONS in small portions timed with the medication (MEDPass). However, it is unknown whether the MEDPass administration enhances patients’ total energy and protein intake.

Methods

The MEDPass Trial is a randomized, controlled, open-label superiority trial. Patients in the MEDPass group receive 50 ml of ONS four times per day, distributed with the medication rounds. Patients in the control group receive ONS between meals. The primary outcome is average daily energy intake (% of calculated daily requirement). For our power analysis, we assumed that administration of ONS in the MEDPass administration mode increases energy intake by at least 10% (i.e., by 200 kcal for an average energy requirement of 2200 kcal/day). Thus, with the inclusion of 200 patients, this trial has 80% power to demonstrate that intervention group patients have an average intake of 2200 kcal/day (SD 500 kcal) versus 2000 kcal/day (SD 500 kcal) in control group patients. Energy and protein intakes from ONS and all food consumed are monitored continuously throughout the hospital stay and are statistically compared to the patient’s requirements. Secondary outcomes include average daily protein intake (% of calculated daily requirement), average intake of ONS/day, the course of body weight, handgrip strength, appetite, and nausea. Furthermore, hospital length of stay and 30-day mortality are assessed. The primary statistical analysis will be performed as an intention-to-treat analysis adjusted for the stratification factors used in randomization.

Discussion

To our knowledge, this is the first randomized controlled trial assessing total energy and protein intake for the entire hospitalization period in patients receiving MEDPass versus conventional ONS administration. Thus, the MEDPass Trial will fill a gap and answer this relevant clinical question.

The Seniors' Community Hub: An Integrated Model of Care for the Identification and Management of Frailty in Primary Care

(1) Background: Integrated models of primary care deliver the comprehensive and preventative approach needed to identify and manage frailty in older people. Seniors' Community Hub (SCH) was developed to deliver person-centered, evidence-informed, coordinated, and integrated care services to older community dwelling adults living with frailty. This paper aims to describe the SCH model, and to present patient-oriented results of the pilot. (2) Methods: SCH was piloted in an academic clinic with six family physicians. Eligible patients were community dwelling, 65 years of age and older, and considered to be at risk of frailty (eFI > 0.12). Health professionals within the clinic received training in geriatrics and interprofessional teamwork to form the SCH team working with family physicians, patients and caregivers. The SCH intervention consisted of a team-based multi-domain assessment with person-centered care planning and follow-up. Patient-oriented outcomes (EQ-5D-5L and EQ-VAS) and 4-metre gait speed were measured at initial visit and 12 months later. (3) Results: 88 patients were enrolled in the pilot from April 2016-December 2018. No statistically significant differences in EQ-5D-5L/VAS or the 4-metre gait speed were detected in 38 patients completing the 12-month assessment. (4) Conclusions: Future larger scale studies of longer duration are needed to demonstrate impacts of integrated models of primary care on patient-oriented outcomes for older adults living with frailty.

Emotional Safety in the Context of Dementia: A Multiperspective Qualitative Study

Background:

Current research acknowledges the relevance of the emotional safety of people living with dementia. However, available evidence regarding this topic is limited. A comprehensive view of this topic that equally considers the perspectives of people living in an early stage of dementia, relatives, and public stakeholders is lacking.

Objective:

This study aimed to obtain a multiperspective view of emotional safety in the context of dementia in the living environment.

Methods:

A descriptive qualitative study was conducted based on data collected through semi-structured guided interviews (n = 14), focus groups (n = 3), guided feedback, and participatory approaches. People living in an early stage of dementia (N = 6), relatives of people living with dementia (N = 11), and public stakeholders (N = 15) were included.

Results:

Considering “social togetherness”, “personal condition”, “health”, “physical environment”, and “society” in the light of “living and learning in relations” are preconditions for understanding emotional safety in the context of dementia. “Living and learning in relations” refers to the interaction of people in the context of dementia and relations to the topic of dementia. The focus lies on the (collective) learning. The individuality of each person and his or her situation is central, related to dementia-related, psychosocial, biographical, physical, and economic factors.

Conclusion:

Our study highlights the relevance of research on emotional safety in the context of dementia. Approaches to improving the emotional safety of people living in an early stage of dementia should consider the complex situations of each target group in relation to each other at the micro, meso, and macro levels.

Habiliter l’ergothérapeute-chercheur à résoudre les enjeux éthiques de la recherche

La recherche est une occupation propice à l’émergence d’enjeux éthiques, en outre parce qu’elle est liée à des conflits d’intérêts parfois difficiles à gérer et se réalise dans un contexte hautement compétitif qui valorise la performance. Alors que les enjeux éthiques de la pratique clinique de l’ergothérapie commencent à être documentés, les enjeux éthiques vécus par les chercheurs en ergothérapie et les moyens qu’ils utilisent pour gérer ces enjeux ne sont quasiment pas documentés. Cet article présente les résultats d’une étude qualitative qui a documenté les moyens (macro, méso et micro) qui sont proposés par des ergothérapeutes-chercheurs pour résoudre les enjeux éthiques de la recherche. Onze ergothérapeutes (n=11) ont participé à la recherche et partagent les moyens qu’ils utilisent ou envisagent pour gérer les enjeux éthiques de la recherche qu’ils vivent comme chercheur. Les moyens proposés par les ergothérapeutes rejoignent plusieurs moyens suggérés dans les écrits, quoique certains moyens proposés dans les écrits relatifs à la relation à établir avec les participants de recherche soient peu abordés par les participants, ce qui est surprenant compte tenu des valeurs humanistes au fondement de la profession d’ergothérapeute. Au final, cet article qui présente une synthèse à la fois des moyens répertoriés dans des écrits pour résoudre les enjeux éthiques de la recherche et ceux discutés par les participants vise à habiliter l’ergothérapeute-chercheur à résoudre les enjeux que pose la recherche académique tout en restant fidèle aux valeurs de la profession.

Evaluation of the feasibility of an error-minimized approach to powered wheelchair skills training using shared control

BACKGROUND

Powered wheelchairs promote participation for people with mobility limitations. For older adults with cognitive impairment, existing training methods may not address learning needs, leading to difficulty with powered wheelchair skills. Error-minimized training, facilitated by shared control technology, may provide learning opportunities more suited to this population.

OBJECTIVE

The objective of this study was to evaluate the feasibility of an error-minimized approach to powered wheelchair skills training using shared control in residential care. Feasibility indicators were hypothesized a priori to be feasible for use in a definitive RCT.

METHODS

A 2 × 2 factorial RCT compared an error-minimized powered wheelchair skills training program (Co-pilot) to a control intervention at two doses (6 sessions vs. 12 sessions). Data were collected on the feasibility of study processes (e.g., recruitment), resources (e.g., participant time), management (e.g., technology reliability), and training outcomes (e.g., adverse events, clinical outcomes).

RESULTS

Twenty-five older adults with cognitive impairment participated in the study. Technical issues were encountered in 14.5% of training sessions. Participants receiving 6 sessions of training adhered better to the treatment than those receiving 12 sessions. All participants learned the skills required for PWC use with minor errors, regardless of the training method or dose. Co-pilot participants and trainers reported feelings of safety and training benefits with the use of shared control technology.

CONCLUSIONS

Individuals with mild to moderate cognitive impairment are able to learn the skills required to drive a powered wheelchair in as few as six training sessions. Further evaluation of the Co-pilot training program is required.IMPLICATIONS FOR REHABILITATIONShared control teleoperation technology may be used to augment learning in older adults with cognitive impairments.Evaluation of the feasibility of use of novel rehabilitation technologies is critical prior to engaging in large-scale clinical research.Individuals with cognitive impairment are able to learn the required skills for operation of a powered wheelchair.
