Stakeholder involvement in the design of a patient-centered comparative effectiveness trial of the "On the Move" group exercise program in community-dwelling older adults

Advancing patient-centered research practices in a pragmatic patient-level randomized clinical trial: A thematic analysis of stakeholder engagement in Emergency Medicine Palliative Care Access (EMPallA)

BACKGROUND

Involving patient and community stakeholders in clinical trials adds value by ensuring research prioritizes patient goals both in conduct of the study and application of the research. The use of stakeholder committees and their impact on the conduct of a multicenter clinical trial have been underreported clinically and academically. The aim of this study is to describe how Study Advisory Committee (SAC) recommendations were implemented throughout the Emergency Medicine Palliative Care Access (EMPallA) trial. EMPallA is a multi-center, pragmatic two-arm randomized controlled trial (RCT) comparing the effectiveness of nurse-led telephonic case management and specialty, outpatient palliative care of older adults with advanced illness.

METHODS

A SAC consisting of 18 individuals, including patients with palliative care experience, members of healthcare organizations, and payers was convened for the EMPallA trial. The SAC engaged in community-based participatory research and assisted in all aspects from study design to dissemination. The SAC met with the research team quarterly and annually from project inception to dissemination. Using meeting notes and recordings we completed a qualitative thematic analysis using an iterative process to develop themes and subthemes to summarize SAC recommendations throughout the project's duration.

RESULTS

The SAC convened 16 times between 2017 and 2020. Over the course of the project, the SAC provided 41 unique recommendations. Twenty-six of the 41 (63%) recommendations were adapted into formal Institutional Review Board (IRB) study modifications. Recommendations were coded into four major themes: Scientific, Pragmatic, Resource and Dissemination. A majority of the recommendations were related to either the Scientific (46%) or Pragmatic (29%) themes. Recommendations were not mutually exclusive across three study phases: Preparatory, execution and translational. A vast majority (94%) of the recommendations made were related to the execution phase. Major IRB study modifications were made based on their recommendations including data collection of novel dependent variables and expanding recruitment to Spanish-speaking patients.

CONCLUSIONS

Our study provides an example of successful integration of a SAC in the conduct of a pragmatic, multi-center RCT. Future trials should engage with SACs in all study phases to ensure trials are relevant, inclusive, patient-focused, and attentive to gaps between health care and patient and family needs.

The use of co-design in developing physical activity interventions for older adults: a scoping review

BACKGROUND

Promoting physical activity (PA) participation in older adults is important for preserving quality of life and functional independence. Co-design has been shown to increase engagement of end-users in health-related policies and interventions. This scoping review aimed to examine how co-design has been used to develop PA interventions for older adults.

METHODS

We searched MEDLINE, EMBASE, AMED, and CINAHL. Peer-reviewed primary research studies that met the following criteria were included: had at least one participant aged ≥60 years involved in the co-design process and the intervention was delivered to individuals whose mean age was ≥60, used co-design methodologies, and any form of PA. After duplicate removal, two or more independent reviewers completed title and abstract and full text screening. Data were extracted from the included studies according to study aims.

RESULTS

Of the 29 included studies, 12 different terms were used to describe co-design with variable operational definitions that we consolidated into five proposed components. Fifteen studies engaged users in a consultative way, 13 studies using collaboration, and one study engaged end-users in consumer-control. No studies involved end-users in the dissemination phase. Further, no studies directly measured the effectiveness of the co-design process. Five categories of barriers and facilitators to co-design were identified including frameworks and methodologies, logistics, relationships, participation, and generalizability.

CONCLUSIONS

There is a large degree of variability in how co-design is used to develop PA interventions for older adults. Our findings can be used by researchers to improve rigor and standardization in this emerging field.

Patients as partners in health research: A scoping review

BACKGROUND

The role of patient involvement in health research has evolved over the past decade. Despite efforts to engage patients as partners, the role is not well understood. We undertook this review to understand the engagement practices of patients who assume roles as partners in health research.

METHODS

Using a recognized methodological approach, two academic databases (MEDLINE and EMBASE) and grey literature sources were searched. Findings were organized into one of the three higher levels of engagement, described by the Patient and Researcher Engagement framework developed by Manafo. We examined and quantified the supportive strategies used during involvement, used thematic analysis as described by Braun and Clarke and themed the purpose of engagement, and categorized the reported outcomes according to the CIHR Engagement Framework.

RESULTS

Out of 6621 records, 119 sources were included in the review. Thematic analysis of the purpose of engagement revealed five themes: documenting and advancing PPI, relevance of research, co-building, capacity building and impact on research. Improved research design was the most common reported outcome and the most common role for patient partners was as members of the research team, and the most commonly used strategy to support involvement was by meetings.

CONCLUSION

The evidence collected during this review advanced our understanding of the engagement of patients as research partners. As patient involvement becomes more mainstream, this knowledge will aid researchers and policy-makers in the development of approaches and tools to support engagement.

PATIENT/USER INVOLVEMENT

Patients led and conducted the grey literature search, including the synthesis and interpretation of the findings.

Development and Validation of Person-Centered Cut-Points for the Figure-of-8-Walk Test of Mobility in Community-Dwelling Older Adults

BACKGROUND

The Figure-of-8-Walk test (F8WT) is a performance measure of the motor skill of walking. Unlike walking speed over a straight path, it captures curved path walking, which is essential to real-world activity, but meaningful cut-points have yet to be developed for the F8WT.

METHODS

A secondary analysis of 421 community-dwelling older adults (mean age 80.7 ± 7.8), who participated in a community-based exercise clinical trial, was performed. Area under receiver operating characteristic curves (AUROCC) were calculated using baseline data, with F8WT performance discriminating different self-reported global mobility and balance dichotomies. Cut-points for the F8WT were chosen to optimize sensitivity and specificity. For validation, F8WT cut-points were applied to postintervention F8WT data. Participants were called monthly for 12 months after intervention completion to record self-reported incident falls, emergency department visits, and hospitalizations; risks of the outcomes were compared between those who performed well and poorly on the F8WT.

RESULTS

F8WT performance times of ≤9.09 seconds and ≤9.27 seconds can discriminate those with excellent (sensitivity = 0.647; specificity = 0.654) and excellent/very good global mobility (sensitivity = 0.649; specificity = 0.648), respectively. A total number of steps ≤17 on the F8WT can discriminate those with excellent/very good/good global balance (sensitivity = 0.646; specificity = 0.608). Compared to those who performed poorly, those who performed well had a lower incidence of negative outcomes: F8WT time ≤9.09 seconds = 46%-59% lower; F8WT time ≤9.27 seconds = 46%-56% lower; F8WT steps ≤17 = 44%-50% lower.

CONCLUSIONS

Clinicians may consider these preliminary cut-points to aid in their clinical decision making, but further study is needed for definitive recommendations.

Association Between Improved Mobility and Distal Health Outcomes

BACKGROUND

We examined the association between improved mobility and distal health outcomes in older adults using secondary analysis of data from a cluster-randomized controlled group exercise trial.

METHODS

Participants were 303 men and women aged ≥65 and older in 32 independent living facilities, senior apartments, and community centers who participated in 12-week group exercise interventions. Included were those who completed ≥1 follow-up phone call regarding outcomes assessment in the following year. Gait speed and 6-minute walk distance (6MWD) were assessed at baseline and immediately after 12-week interventions to determine mobility performance change status. Falls, emergency department (ED) visits, and hospitalizations were assessed monthly for 12 months following the end of interventions via interactive voice response phone calls. Incident rate ratios (IRRs) were calculated to quantify incidence of adverse outcomes with respect to mobility performance change.

RESULTS

Each 0.05 m/s increase in gait speed resulted in an 11% reduction in falls (IRR = 0.89; 95% confidence interval [CI], 0.84-0.94; p < .0001); a similar decrease was seen for each 20 m increase in 6MWD (IRR = 0.89; 95% CI, 0.83-0.93; p = .0003). Those who improved gait speed had 61 falls per 1,000 person-months versus 135 in those who had no change/a decline. Those who improved 6MWD had 67 falls per 1,000 person-months versus 110 per 1,000 person-months in those who had no change/a decline. Differences in ED visits and hospitalizations were not statistically significant.

CONCLUSION

Improvements in mobility performance are associated with lower incidence of future falls. Given the exploratory nature of the findings, further investigation is warranted.

A systematic review on implementation of person-centered care interventions for older people in out-of-hospital settings

THE PURPOSE

of this study was to explore the content and essential components of implemented person-centered care in the out-of-hospital context for older people (65+).

METHOD

A systematic review was conducted, searching for published research in electronic databases: PubMed, CINAHL, Scopus, PsycInfo, Web of Science and Embase between 2017 and 2019. Original studies with both qualitative and quantitative methods were included and assessed according to the quality assessment tools EPHPP and CASP. The review was limited to studies published in English, Swedish, Danish, Norwegian and Spanish.

RESULTS

In total, 63 original articles were included from 1772 hits. The results of the final synthesis revealed the following four interrelated themes, which are crucial for implementing person-centered care: (1) Knowing and confirming the patient as a whole person; (2) Co-creating a tailored personal health plan; (3) Inter-professional teamwork and collaboration with and for the older person and his/her relatives; and (4) Building a person-centered foundation.

CONCLUSION

Approaching an interpersonal and inter-professional teamwork and consultation with focus on preventive and health promoting actions is a crucial prerequisite to co-create optimal health care practice with and for older people and their relatives in their unique context.

Potential long-term impact of "On The Move" group-exercise program on falls and healthcare utilization in older adults: an exploratory analysis of a randomized controlled trial

Background

Wellness program participation may reduce the risk of falling, emergency department-use, and hospitalization among older adults. “On the Move” (OTM), a community-based group exercise program focused on the timing and coordination of walking, improved mobility in older adults, but its impact on falls, emergency department-use, and hospitalizations remains unclear. The aim of this preliminary study was to investigate the potential long-term effects that OTM may have on downstream, tertiary outcomes.

Methods

We conducted a secondary analysis of a cluster-randomized, single-blind intervention trial, which compared two community-based, group exercise programs: OTM and a seated exercise program on strength, endurance, and flexibility (i.e. ‘usual-care’). Program classes met for 50 min/session, 2 sessions/week, for 12 weeks. Older adults (≥65 years), with the ability to ambulate independently at ≥0.60 m/s were recruited. Self-reported incidence of falls, emergency department visitation, and hospitalization were assessed using automated monthly phone calls for the year following intervention completion. Participants with ≥1 completed phone call were included in the analyses. Incidence rate ratios (IRRs) and 95% confidence intervals (CIs) were calculated (reference = usual-care).

Results

Participants (n = 248) were similar on baseline characteristics and number of monthly phone calls completed. Participants in the seated exercise program attended an average of 2.9 more classes (p = .017). Of note, all results were not statistically significant (i.e. 95% CI overlapped a null value of 1.0). However, point estimates suggest OTM participation resulted in a decreased incidence rate of hospitalization compared to usual-care (IRR = 0.88; 95% CI = 0.59–1.32), and the estimates strengthened when controlling for between-group differences in attendance (adjusted IRR = 0.82; 95% CI = 0.56–1.21). Falls and emergency department visit incidence rates were initially greater for OTM participants, but decreased after controlling for attendance (adjusted IRR = 1.08; 95% CI = 0.72–1.62 and adjusted IRR = 0.96; 95% CI = 0.55–1.66, respectively).

Conclusion

Compared to a community-based seated group exercise program, participation in OTM may result in a reduced risk of hospitalization. When OTM is adhered to, the risk for falling and hospitalizations are attenuated. However, definitive conclusions cannot be made. Nevertheless, it appears that a larger randomized trial, designed to specifically evaluate the impact of OTM on these downstream health outcomes is warranted.

Assessing gait efficacy in older adults: An analysis using item response theory

BACKGROUND

Assessing confidence in walking in older adults is important, as mobility is a critical aspect of independence and function, and self-report provides complementary information to performance-based measures. The modified Gait Efficacy Scale (mGES) is a self-report measure used to examine confidence in walking.

RESEARCH QUESTION

What are the psychometric properties of the mGES at the item level? Are there opportunities for improvement?

METHODS

We performed a secondary analysis of baseline data from a cluster randomized trial of 424 community-dwelling older adults and reliability data from 123 participants. We fitted a graded response model to dissect the mGES to the item and individual response level and examined opportunities to improve and possible shorten the mGES. We examined psychometric characteristics such as internal consistency, test-retest reliability and construct validity with respect to other relevant measures.

RESULTS

Mobility tasks such as navigating stairs and curbs with separate items for going up and down largely provide the same information on confidence, with downward direction providing slightly more. It may be reasonable to consider removal of walking 1/2 mile, stepping down and/or stair tasks with railings items due to little or duplicate information contributed compared to other items. The shortened scales proposed by removing the above items had similar psychometric properties to mGES.

SIGNIFICANCE

The mGES has good psychometric properties, but can be potentially shortened to substantially reduce responder burden. The upward direction curb and stairs items can be removed to result in a 7-item scale with virtually no loss of desirable psychometrics. An alternative 3-item version, level surface walking, stepping down curb and climbing up stairs without a railing items, entails only a minimal loss in psychometric properties.

A Patient-Centered Approach to Comparative Effectiveness Research Focused on Older Adults: Lessons From the Patient-Centered Outcomes Research Institute

The mission of the Patient-Centered Outcomes Research Institute (PCORI) is to fund the production of high-quality evidence that will enable patients and clinicians to make informed, personalized healthcare decisions. Since 2012, the PCORI has invested $177 million in patient-centered comparative effectiveness research (CER) that specifically targets the health needs of older adults, with additional relevant studies in its broader portfolio. Developing the PCORI's research portfolio has provided us with significant insights into what factors to consider when conducting CER in older adult populations. When comparing the net benefit of two or more interventions for older adults, investigators should consider the following: absolute risk difference, competing risks, life expectancy, the difference between chronologic and physiologic age, the importance of patient preferences, and other potential drivers of variable treatment effects. Investigators should also engage older adults and their caregivers as partners throughout the research process. Their input helps to identify key outcomes of interest and insights about the conduct of the research. As the PCORI continues to support research that addresses the healthcare decisions of the rapidly growing older adult population, it needs to partner with patients and researchers to identify the most important questions to address.

Intraclass Correlation Coefficients for Planning Cluster Randomized Trials in Community-Dwelling Older Adults

Objectives: With the emerging trends, more cluster randomized trials will be conducted in older adults, where facilities are randomized rather than individuals. Similarity of individuals from a facility (intraclass correlation coefficient/ICC) plays a critical role, but not readily available. We document ICCs for measures commonly used in community-dwelling older adults and discuss implications. Method: Secondary analysis of a range of baseline measures from the On the Move cluster randomized trial, whose ICCs were computed using a linear mixed model. Results: Self-reported disability measures related to facility characteristics and sense of community had the greatest ICCs (>0.10), while mobility performance measures had 0.05 to 0.10, and cognitive measure 0.11. Discussion: The ICCs for measures commonly used in older adults are of a sufficient magnitude to have a substantial impact on planned sample size of a study and credibility of results, and should be taken into consideration in study planning and data analysis.

Integrated primary and geriatric care for frail older adults in the community: Implementation of a complex intervention into real life

BACKGROUND

Frailty is highly prevalent in older persons and associated with negative health-related events and costs. Despite successful clinical trials, translation of evidence into implementation of dedicated programs has been scarce. This is probably due to funding limitations and lack of generalizability of rigid schemes adopted in controlled studies. We propose a guidance to implement complex interventions against frailty in the community, and describe the design and early findings of the +AGIL Barcelona program.

METHODS

A guidance "decalogue" resulted from an experts' panel prioritization of recommendations by international independent bodies. On this basis, we reorganized existing primary care, geriatrics and community-based resources to implement our program, which includes a screening, a multi-component intervention modulated on the comprehensive geriatric assessment and integrated follow-up plus continuity through community-based resources. The pre-post impact of the program on physical function, as well as on clinical endpoints, person-center outcomes and costs will be assessed.

RESULTS

Integrated care, multi-component, person-centered strategies to empower the final users in a flexible and adaptable way should be promoted after raising awareness and potentially convey long term investments. In 22 months, 185 participants (mean age ± SD = 81.6 ± 5.7 years, 72% women) joined the program. Although independent in the activities of daily living, participants showed clear indicators of frailty (Short Physical Performance Battery = 7.1 ± 2.5; gait speed = 0.69 ± 0.2 m/s).

CONCLUSIONS

+AGIL Barcelona may represent a unique model to manage frailty in older community-dwellers, translating evidence into pragmatic clinical practice. Further research will clarify the effects of this intervention.

Multimorbidity in Older Adults With Cardiovascular Disease

Multimorbidity occurs in adults of all ages, but the number and complexity of comorbid conditions commonly increase with advancing age such that cardiovascular disease (CVD) in older adults typically occurs in a context of multimorbidity. Current clinical practice and research mainly target single disease-specific care that does not embrace the complexities imposed by concurrent conditions. In this paper, emerging concepts regarding CVD in combination with multimorbidity are reviewed, including recommendations for incorporating multimorbidity into clinical decision making, critical knowledge gaps, and research priorities to optimize care of complex older patients.

The Role of the Environment on Sedentary Behavior in Community-Dwelling Older Adults

Objectives

To compare amounts of sedentary behavior and physical activity in adults residing in planned group residential settings to those residing in private homes.

Methods

Thirty-one older adults who resided in planned group residential settings (n=13) and in private homes (n=18) participated. Daily activities were measured using the Sensewear Armband for 7 days. Estimates of the duration of daily activities performed across sedentary, light, and moderate-to-vigorous intensities were captured.

Results

Participants in planned group residential settings were older (age 85.9±3.5 vs 78.3±7.2; p=0.001) and spent more time in sedentary behaviors (12.7±1.5 vs 11.3±1.6; p=0.02) than participants in private homes. The difference was attenuated slightly after controlling for age and wear time (adjusted difference 1.2±0.6 hours, p=0.06).

Discussion

Adults residing in planned group residential settings, which provide supportive services, were more sedentary than adults residing in private homes. The environment in which older adults live may contribute to sedentary behavior.

Motor Control-based Group Exercise: Can It be Delivered as Effectively by Lay Leaders?

PURPOSE

On the Move (OTM), a motor control-based group exercise program for community-dwelling older adults, has produced greater gains in mobility than a standard group exercise program when delivered by research leaders. The purposes of this study were:1) to examine the effectiveness of OTM versus a standard program when delivered by lay leaders and 2) to compare the outcomes of OTM when delivered by research versus lay leaders.

METHODS

Community-dwelling, medically stable older adults who could walk household distances participated. OTM consisted of warm-up, timing and coordination, strengthening, and stretching exercises. The seated standard program consisted of warm-up, aerobic, strengthening and stretching exercises. The primary outcome(s) of function and disability was the Late Life Function and Disability Instrument (LLFDI), and for walking ability were the Six Minute Walk Test and gait speed.

RESULTS

126 participants (mean age = 80.7±7.8 years, gait speed = 0.91 m/s) were randomized to OTM (n=49) or standard (n=77) programs. When taught by lay leaders, there were no significant between-intervention group differences in any of the outcomes (p>0.10). Comparing OTM outcomes between leaders, there was a statistical but not clinically meaningful difference in LLFDI disability (1.87±0.89, p=0.04) when taught by research versus lay leader, and moderate differences (p=0.06) in LLFDI overall function (1.89±1.02) and gait speed (0.05±0.03). Qualitative interview responses suggest that instructor-related concerns may have impacted program outcomes.

CONCLUSION

When delivered by lay leaders OTM was not more effective than a standard program for improving function, disability, and mobility in older adults. Health promotion programs designed to improve mobility in community-dwelling older adults and based on a motor control theoretical background, may be best taught by rehabilitation professionals.

Effectiveness of a Timing and Coordination Group Exercise Program to Improve Mobility in Community-Dwelling Older Adults: A Randomized Clinical Trial

IMPORTANCE

Timing and coordination exercises may be an important addition to community-based health promotion exercise programs to improve walking in older adults.

OBJECTIVE

To compare the effectiveness of the On the Move group exercise program, which focuses on the timing and coordination of movement, with a seated strength, endurance, and flexibility program (usual care) at improving function, disability, and walking ability of older adults.

DESIGN, SETTING, AND PARTICIPANTS

Cluster-randomized, single-blind intervention trial. Thirty-two independent living facilities, senior apartment buildings, and senior community centers were randomized to On the Move (16 sites; 152 participants) or usual care (16 sites; 146 participants). Participants were 65 years or older, able to ambulate independently with a gait speed of at least 0.60 m/s, able to follow 2-step commands, and were medically stable.

INTERVENTIONS

Exercise classes were 50 minutes, twice a week for 12 weeks and had 10 or fewer participants per class. On the Move consisted of warm-up, timing and coordination (stepping and walking patterns), strengthening, and stretching exercises. The usual-care program consisted of warm-up, strength, endurance, and stretching exercises.

MAIN OUTCOMES AND MEASURES

The primary outcomes were self-report of function and disability (Late Life Function and Disability Instrument) and mobility (6-minute walk distance and gait speed) assessed by blinded individuals.

RESULTS

Participants (mean [SD] age, 80.0 [8.1] years) were mostly female (251 [84.2%]) and white (249 [83.6%]) and had a mean (SD) of 2.8 (1.4) chronic conditions. Intervention groups were similar on baseline characteristics. Postintervention, 142 (93.4%) participants in On the Move and 139 (95.2%) participants in usual care completed testing. On the Move had greater mean (SD) improvements than the usual-care group in gait speed (0.05 [0.13] vs -0.01 [0.11] m/s; adjusted difference = 0.05 [0.02] m/s; P = .002) and 6-minute walk distance (20.6 [57.1] vs 4.1 [55.6] m; adjusted difference = 16.7 [7.4] m; P = .03). Attendance was greater in the usual-care program compared with On the Move (95 [65.1%] vs 76 [50.0%] attended ≥20 classes; P = .03). There were no significant differences in any of the other primary or secondary outcomes.

CONCLUSIONS AND RELEVANCE

The On the Move group exercise program was more effective at improving mobility than a usual-care exercise program, despite lower attendance. Additional research examining the impact of the intervention on long-term disability outcomes is needed before recommending routine implementation into clinical practice.
