Effectiveness and Implementation of an EnhanceFitness Physical Activity Intervention Specifically in Adults With Arthritis: A RE-AIM Evaluation.

This study evaluated the effectiveness of the evidence-based, EnhanceFitness (EF) physical activity (PA) intervention in improving arthritis symptoms, physical and mental function, and PA in adults with arthritis. This was a community-based, randomized, controlled effectiveness trial that switched to a nonrandomized controlled trial. Participants were sedentary/low-active adults, aged ≥18 years, with self-reported physician-diagnosed arthritis, who were assigned to an immediate or delayed group (12-week, wait-list control group). Classes were held thrice weekly for 12 weeks at 17 community sites in 4 urban and 5 rural West Virginia counties. Data were collected at baseline, 12 weeks, and 24 weeks. The RE-AIM Framework evaluated EF's: (1) reach (enrollment); (2) effectiveness (outcomes); (3) adoption (proportion of sites/instructors that delivered EF); (4) implementation (attendance, fidelity, adverse events, and satisfaction); and (5) maintenance (EF continuation). Outcomes were analyzed using linear mixed-effects regression. There were 323 adults with a mean age of 68.3 years (range 27-95). Reach was 74%; site and instructor adoption rates were 100% and 55%, respectively; attendance (1.8 sessions per week) and fidelity were good; injury rate was low (3.8%); participants were highly satisfied and experienced improvements in arthritis symptoms and physical function; and 27% of instructors and 18% of sites continued EF. EnhanceFitness was safe and effective in improving arthritis symptoms and physical function in sedentary/low-active adults with arthritis, across the adult age spectrum, under real-world conditions, in both urban and rural communities.Clinical Trial Registration: NCT00526201.

Remotely Delivered Exercise to Rural Older Adults With Knee Osteoarthritis: A Pilot Study.

ObjectiveEnhanceFitness (EF) is an evidence‐based exercise program recommended for management of osteoarthritis (OA). However, access to EF is limited in rural areas. Accordingly, we evaluated the feasibility and acceptability of remotely delivered EF (tele‐EF) in rural, community‐dwelling older adults with symptomatic knee OA.MethodsA single‐arm pilot trial of tele‐EF classes was conducted. Videoconferencing was used to livestream the instructor‐led, 1‐hour EF classes 3 days/week for 12 weeks. Outcomes were assessed at baseline and immediately post intervention.ResultsA total of 15 of 27 potential participants (55%) were screen eligible and enrolled into the trial. Participants had a median age of 70 years (interquartile range: 67‐75), and 14 (93%) were women. The median EF class attendance rate was 91% (interquartile range: 85%‐94%). Knee pain, as measured by the Knee Injury and Osteoarthritis Outcome Score (KOOS), improved significantly from baseline to the 12‐week end point (mean difference = −11.4 [95% confidence interval (CI): −20.9 to −2.0]; P = 0.02). In addition, participants’ self‐reported knee function improved significantly (mean difference in KOOS function score = −11.8 [95% CI: −18.4 to −5.2]; P < 0.01) as well as their physical capacity (mean difference in Timed Up and Go test time = 1.8 seconds [95% CI: 0.2‐3.4]; P = 0.03). All participants (100%) were very satisfied with tele‐EF classes, and 12 participants (86%) reported that their condition had much improved or very much improved since beginning the EF exercise program. Lastly, there were no serious adverse events.ConclusionFindings from this pilot trial indicate that tele‐EF is feasible and acceptable in rural older adults with knee OA.

Predictors of Improvement in Physical Function in Older Adults in an Evidence-Based Physical Activity Program (EnhanceFitness).

Declines in strength, flexibility, and balance in older adults can lead to injuries and loss of independence and are particularly common in those of greater age and in worse health. EnhanceFitness (EF) is a nationally disseminated, evidence-based group exercise program for older adults that has been shown to improve function through cardiovascular, strength, flexibility, and balance exercises. This article examines changes in, and predictors of, participant physical function from baseline through 2 program cycles of EF as measured by 3 physical function tests: arm curls, chair stands, and 8-foot up-and-go. We analyzed data on participants who attended at least 2 consecutive 16-week program cycles between January 2005 and June 2016. We ran 3 random-effects linear regression models, 1 for each physical function test, and accounted for missing data and clustering by class site. Independent variables included attendance, demographics, and health status. A total of 7483 participants completed baseline and 2 sets of follow-up physical function tests. For all 3 physical function tests, participants showed some degree of improved physical function at each follow-up, and greater program attendance predicted clinically significant improvements. Some participants had less improvement: females, those less active at baseline, older than 75 years, not married or partnered, or in fair or poor health, those who had experienced at least 1 fall, and those with a disability. EnhanceFitness program providers may need to implement additional measures to support the participants who could benefit most from EF, such as targeting messaging, coordinating with referring providers to emphasize attendance and general activity in specific participants, and offering additional support to groups who show less improvement during classes. The evidence presented here may inform clinical decision making for older adult patients and increase health care provider confidence in EF and similar exercise programs, thereby providing a mechanism to maintain and continue functional gains made in clinical or rehabilitation settings.

Determining the Long-Term Effectiveness of a Group-Based Physical Activity Program.

In 2015, only half (48%) of older adults in the United States (≥60 years) reported engaging in any kind of physical activity. Few studies examine the impact of evidence-based programs when adopted in community-based settings. The purpose of this study is to assess the effectiveness of EnhanceFitness (EF) upto 12-months. EF was offered to older adults in South Florida. A total of 222 EF classes were offered between October 2008 and December 2014. Program consisted of a 1-hour session held three times a week. Even though participation was required for 4 months, 1,295 participants continued the program for at least 1 year. All participants showed significant improvement in outcome measures. A mean change of 1.5, 1.7, and 1.9 was seen in number of chair stands at 4, 8, and 12 months (p < .001), respectively. The number of arm curls performed improved from 16.8 at baseline to 18.8, 18.8, and 19.2 at 4-, 8-, and 12-months, respectively. Participants improved their up-and-go time by decreasing from 9.1 (baseline) to 8.7 (4 months) to 8.6 (12 months; p = .001). Randomized controlled trials are commonly used to determine the efficacy of an intervention. These interventions when disseminated at the population level have the potential to benefit large masses. EF is currently offered at more than 700 locations. This tremendous success of EF brings attention to an important question of continuous monitoring of these programs to ensure program consistency and intended outcomes. The model used by the Healthy Aging Regional Collaborative could be replicated by other communities.

Enhance®Fitness Dissemination and Implementation,: 2010–2015: A Scoping Review

Physical activity has many benefits for older adult physical and mental health. Enhance®Fitness (EF) is an evidence-based group exercise program delivered by community-based organizations. The purpose of this study was to review recent evidence on the dissemination and implementation of EF. A scoping review of qualitative and quantitative studies with EF as main focus was conducted. CINAHL, PubMed, PubMed Central, SCOPUS, Web of Science, PsycINFO, and Google Scholar were searched between October and November 2015 for data-based studies on EF published in 2010-2015. Two team members abstracted each paper independently using a data abstraction tool. Results were summarized using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. Seventeen publications met inclusion criteria. EF has reached and is effective across a broad population base, including individuals with low SES and diverse ethnic/racial backgrounds. EF participation may be associated with reduced risk for falls requiring medical care, and is associated with fewer hospital admissions. Analyses of medical cost savings from EF participation and program implementation costs suggest economic benefits of EF implementation for communities. Organization-level maintenance is facilitated by program-specific and organizational factors, such as instructor training and funding. Individual-level maintenance is facilitated by program structure, absence of pain, and increased quality of life. More-rigorous evidence is needed about the association between participation in EF and conditions such as falls. Evaluation of program fidelity, adaptations, and sustainability is limited; more-systematic examination across population groups and types of organizations would help ensure older adults continue to benefit from EF participation.

Evaluating the Factors Associated With the Completion of a Community-Based Group Exercise Program Among Older Women.

Despite the well-known benefits of exercise, only 50% of U.S. women met recommended physical activity levels in 2014. To combat this issue, the Healthy Aging Regional Collaborative of South Florida has been offering the EnhanceFitness (EF) program in community-based settings since 2008. In the current study, we examined the factors associated with the program completion among older women (≥ 60 years). During the first 4 years, 3,829 older women attended EF sessions. Of these, 924 (24.2%) attended the recommended 32 sessions within first 4 months. Results revealed that women who lived in Miami-Dade County, were ≥ 80 years, and did not report depression and/or risk factors for chronic conditions were more likely to complete EF. Black women were less likely to complete the program. Recognition of these factors might help identify at-risk individuals. More efforts are needed to improve completion rates. Theory-based interventions would allow comprehensive understanding of all factors and, therefore, should be explored in the future.

Champions of an Older Adult Exercise Program: Believers, Promoters, and Recruiters.

Champions, who support, market, and promote programs, are a vital part of successful program adoption, implementation, and maintenance. Enhance®Fitness (EF) is an evidence-based, community-delivered group exercise program for older adults. Using semistructured phone interviews with 20 participants, 17 instructors, and 15 staff, we explored the roles of champions in adopting, implementing, and maintaining EF at YMCA-affiliated sites. Interviews revealed EF champions play critical roles in program dissemination. Champions are outgoing, passionate, and enthusiastic about EF. They believe in the program and its benefits (believers), are "walking advertisements" (promoters), and have magnetic personalities, persuading newcomers to join (recruiters). EF champions were not purposefully selected but naturally arose during the course of program delivery. Community sites adopting evidence-based programs can foster and support champions by engaging with them, and capitalizing on their energy as an emerging resource throughout the adoption, implementation, and maintenance of programs.

Implementation of an Evidence-Based Exercise Program for Older Adults in South Florida.

Introduction. This study aimed to examine how well an evidence-based physical activity program could be translated for wide scale dissemination and adoption to increase physical activity among community-dwelling older adults. Methods. Between October 2009 and December 2012, reach, fidelity, dosage, ease of implementation, and barriers to translation of EnhanceFitness (EF) were assessed. To assess effectiveness, a pretest-posttest design was used to measure increases in functional fitness (chair stands, arm curls, and the up-and-go test). Results. Fourteen community-based agencies offered 126 EF classes in 83 different locations and reached 4,490 older adults. Most participants were female (72%). Thirty-eight percent of participants did not complete the initial 16-week EF program. The 25% who received the recommended dose experienced an increase in upper and lower body strength and mobility. Further, participants reported high satisfaction with the program. Conclusion. EF was successfully implemented in a variety of settings throughout South Florida and reached a large number of older adults. However, challenges were encountered in ensuring that those who participated received a program dose that would lead to beneficial gains in functional fitness.

A Pilot Study of Determinants of Ongoing Participation in EnhanceFitness: A Community-Based Group Exercise Program for Older Adults.

Physical activity has many benefits for older adults, but adherence is often low. The purposes of this study were to (1) identify motivators and barriers for participation in EnhanceFitness (EF), a group-based exercise program; and (2) quantitatively examine the association between motivators, barriers and individual characteristics, and ongoing participation in the program. This was a prospective, cross-sectional study. We mailed a pilot, investigator-developed survey to assess motivators and barriers to exercising to 340 adults who started a new EF class, regardless of their attendance rate. We precoded surveys on the basis of class attendance, with former participants defined as having no attendance a month or more before a 4-month fitness check. Of the 241 respondents (71% response rate), 61 (25%) were precoded as former participants and 180 (75%) as current participants. The mean age of respondents was 71 years and they were predominately female (89%). More than half of respondents were whites (58%), and almost half were married (46%). Former participants reported lower total motivation scores than current participants (P < .01) and had a significantly higher mean total barrier score (P < .001). The effects of 5 barriers ("Class was too hard," "Class was too easy," "I don't like to exercise," "Personal illness," and "Exercise caused pain") and 2 motivators ("I want to exercise" and "I plan exercise as part of my day") were significantly different between current and former participants. Discrete event history models show that dropout was related positively to ethnicity (whites were more likely to drop out) and health-related barriers. In newly formed EF classes, participants who drop out report more program, psychosocial, and health barriers, and fewer program and psychosocial motivators. Total barrier score and health barriers significantly predict a participant's dropping out, and white ethnicity is associated with a higher likelihood of dropping out. Employing strategies that address health barriers to participation could improve attendance rates for group-based exercise programs.

Beyond Strength: Participant Perspectives on the Benefits of an Older Adult Exercise Program.

This study examines the expected and experienced benefits among participants in Enhance®Fitness (EF), an evidence-based group physical activity program for older adults. We also describe the implications for program dissemination (reach, implementation, and maintenance) within the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework. Twenty semistructured interviews were conducted with EF participants enrolled from 2005 to 2012. Interviews were digitally recorded, professionally transcribed, and analyzed using a deductive approach. Participants were motivated to join EF for expected physical benefits and the social environment of a group-based class. Actualized benefits of participation included physical, social, functional, and improved self-image/sense of well-being. Participants valued the practical application of class exercises to daily activities that support independent living, such as lifting objects and completing household chores. Organizations looking to implement EF or improve existing EF classes can improve program reach, implementation, and maintenance by incorporating participants' expressed motivations and valued benefits in program marketing and by improving organizational support to meet participant needs. EF class instructors can tailor their classes to engage participants based on their motivations. Understanding participants' motivations and valued benefits can improve EF dissemination by meeting participant needs with tailored class offerings and organizational needs informed by participant insights that aid program sustainability.

National dissemination of multiple evidence-based disease prevention programs: reach to vulnerable older adults.

Older adults, who are racial/ethnic minorities, report multiple chronic conditions, reside in medically underserved rural areas, or have low incomes carry a high burden of chronic illness but traditionally lack access to disease prevention programs. The Chronic Disease Self-Management Program (CDSMP), A Matter of Balance/Volunteer Lay Leader (AMOB/VLL), and EnhanceFitness (EF) are widely disseminated evidence-based programs (EBP), but the extent to which they are simultaneously delivered in communities to reach vulnerable populations has not been documented. We conducted cross-sectional analyses of three EBP disseminated within 27 states throughout the United States (US) (2006–2009) as part of the Administration on Aging (AoA) Evidence-Based Disease and Disability Prevention Initiative, which received co-funding from the Atlantic Philanthropies. This study measures the extent to which CDSMP, AMOB/VLL, and EF reached vulnerable older adults. It also examines characteristics of communities offering one of these programs relative to those simultaneously offering two or all three programs. Minority/ethnic participants represented 38% for CDSMP, 26% for AMOB/VLL, and 43% for EF. Rural participation was 18% for CDSMP, 17% for AMOB/VLL, and 25% for EF. Those with comorbidities included 63.2% for CDSMP, 58.7% for AMOB/VLL, and 63.6% for EF while approximately one-quarter of participants had incomes under $15,000 for all programs. Rural areas and health professional shortage areas (HPSA) tended to deliver fewer EBP relative to urban areas and non-HPSA. These EBP attract diverse older adult participants. Findings highlight the capability of communities to serve potentially vulnerable older adults by offering multiple EBP. Because each program addresses unique issues facing this older population, further research is needed to better understand how communities can introduce, embed, and sustain multiple EBP to ensure widespread access and utilization, especially to traditionally underserved subgroups.

Implementation and Maintenance of a Community-Based Older Adult Physical Activity Program.

We examine facilitators and barriers to the implementation and maintenance of Enhance®Fitness (EF), a group exercise program for older adults, at early-adopter YMCA-affiliated sites, and summarize strategies employed by EF instructors and staff to overcome challenges. This qualitative study used semi-structured phone interviews with 32 instructors, staff members, and master trainers from 24 different YMCA-affiliated sites. Interviews were digitally recorded, transcribed, and analyzed with a focus on the implementation and maintenance components of the RE-AIM framework. We identified a series of factors affecting the implementation and maintenance of EF at YMCA-affiliated sites, which can be categorized into program-specific (such as instructor training, the structure of the program, reporting requirements, and insurance coverage), and organizational (such as organizational support and infrastructure for program delivery, champions, and funding to cover the costs of program delivery). Strategies used to overcome challenges associated with these factors include identifying parts of the program that can be adapted, hiring staff and instructors that understand and support the program, and educating staff and instructors about the importance of evidence-based programs and of data collection for program evaluation. Assessing the readiness of organizations for program delivery and the match between program goals and the needs of organizations and participants would help facilitate the successful implementation and maintenance of physical activity programs in community settings.

From Research to Practice

Successful health promotion and disease prevention efforts require not only the development of evidence-based programs but also the broad dissemination of those programs. In this article, we trace the development and dissemination of an evidence-based exercise program for older adults, EnhanceFitness (EF). We summarize its effectiveness, describe its adoption by partners, and highlight best practices related to program maintenance. We organize the article around a program planning and evaluation framework called RE-AIM. The EF enterprise remains robust because of its scientific evidence (it works), easy replicability, low-cost, strong advocates, timely technical assistance, and affiliation with an academic partner.

Healthcare Cost Differences with Participation in a Community‐Based Group Physical Activity Benefit for Medicare Managed Care Health Plan Members

To determine whether participation in a physical activity benefit by Medicare managed care enrollees is associated with lower healthcare utilization and costs. Retrospective cohort study. Medicare managed care. A cohort of 1,188 older adult health maintenance organization enrollees who participated at least once in the EnhanceFitness (EF) physical activity benefit and a matched group of enrollees who never used the program. Healthcare costs and utilization were estimated. Ordinary least squares regression was used, adjusting for demographics, comorbidity, indicators of preventive service use, and baseline utilization or cost. Robustness of findings was tested in sensitivity analyses involving continuous propensity score adjustment and generalized linear models with nonconstant variance assumptions. EF participants had similar total healthcare costs during Year 1 of the program, but during Year 2, adjusted total costs were $1,186 lower (P=.005) than for non-EF users. Differences were partially attributable to lower inpatient costs (-$3,384; P=.02), which did not result from high-cost outliers. Enrollees who attended EF an average of one visit or more per week had lower adjusted total healthcare costs in Year 1 (-$1,929; P<.001) and Year 2 (-$1,784; P<.001) than nonusers. Health plan coverage of a preventive physical activity benefit for seniors is a promising strategy to avoid significant healthcare costs in the short term.

The Effects of a Community-Based Exercise Program on Function and Health in Older Adults: The EnhanceFitness Program

This study examined the effectiveness of participation in EnhanceFitness (EF) (formerly the Lifetime Fitness Program), an established community-based group exercise program for older adults. EF incorporated performance and health status measure testing in year 2000. Initial performance was compared to age and gender-based norms to classify participants as within or at or above normal limits (WNL) or below (BNL). In 2,889 participants who participated in outcomes testing, improvements were observed at 4 and 8 months on performance tests for both subgroups. Participants’ self-rating of health improved at 8 months. All participants improved on performance tests. Implementation of performance-based measures in community studies is possible. Challenges included selecting measures, staff training, collecting performance measures, and deciding on time points for data collection. Older adults can maintain and/or improve physical function through participation in EnhanceFitness.
