Translating the Lifestyle Interventions and Independence for Elders Clinical Trial to Older Adults in a Real-World Community-Based Setting

"You Just Have to Keep It Movin':" Perceptions of Physical Function Limitations in an African American Health Ministry

Physical function (PF) limitations are common in aging. However, there is a dearth of interventions focused on addressing PF limitations in community-based settings, particularly in minoritized communities. To guide intervention development, we conducted focus groups to understand perceptions of PF limitations, gauge intervention interest, and identify potential intervention strategies as part of a large health partnership of African American churches in Chicago, IL. Participants were age 40+ years with self-reported PF limitations. Focus groups (N=6 focus groups; N=40 participants) were audio recorded, transcribed, and analyzed using thematic analysis methods.Six themes were identified: (1) causes of PF limitations, (2) impact of PF limitations, (3) terminology and communication, (4) adaptations and treatments, (5) faith and resilience, and (6) prior program experiences. Participants described how PF limitations affected their ability to live a full life and play an active role in their family, church, and community. Faith and prayer aided in coping with limitations and pain. Participants expressed that it is important to keep moving, both from an emotional (not giving up) and physical (to prevent further exacerbation of limitations) standpoint. Some participants shared adaptation and modification strategies, but there were overall frustrations with communicating regarding PF limitations and obtaining medical care for them. Participants expressed that they would like to have programs in their church focused on improving PF (including physical activity), particularly as their communities often lacked resources conducive to being active. Community-based programs focusing on reducing PF limitations are needed, and the church is a potentially receptive setting.

Exercise based reduction of falls in communitydwelling older adults: a network meta-analysis

BACKGROUND

Traditional meta-analyses with pairwise direct comparison revealed that a variety of exercise-based training interventions can prevent falls in community-dwelling older adults. This network meta-analysis adds value by comparing and ranking different exercise training strategies based on their effects on fall risk reductions determined by analysis of direct and indirect comparisons.

METHODS

The studies included in this network meta-analysis were identified through a comprehensive search in five biomedical databases (PubMed, SportDiscus, CINAHL, Web of Science and EMBASE). We included (randomized) controlled trials (RCTs) that compared the occurance of fall events in older adults who received different interventional treatments.

RESULTS

Seventy six comparisons from 66 RCTs with 47.420 (61% male / 39% female) participants aged 77 ± 4 (68 - 88) years were included in this network meta-analysis. The network model revealed low heterogeneity (I² = 28.0, 95%CI 1.0 to 47.7%) and inconsistency (Q between designs = 15.1, p = 0.37). Postural control training was found to be most effective in preventing falls (Postural Control Training: (home): Risk Ratio (RR) = 0.66, 95%-CI [0.49; 0.88], P-score = 0.97;Postural Control Training: RR = 0.82, 95%-CI [0.75; 0.91], P-score = 0.82). Combined and multifactorial interventions also display a robust but smaller effect (RR = 0.88-0.93, P-score = 0.65-0.47).

CONCLUSION

Physical activity that includes balance training presents itself to be the most effective. Multifactorial approaches are well investigated but could be slightly less effective than isolated postural control training.

Effective implementation approaches for healthy ageing interventions for older people: A rapid review

BACKGROUND AND OBJECTIVES

Systematic reviews on healthy ageing interventions have primarily focused on assessing their effectiveness, not the implementation processes underpinning them, and the factors influencing program effectiveness. This has created a knowledge gap about what are effective implementation approaches, and how to scale up such interventions at the population level. Our aim in this rapid review was to synthesise the evidence on implementation of effective healthy ageing interventions, and to identify the factors that influence population-level implementation of these interventions.

DESIGN AND METHODS

Following the PRISMA checklist, we searched for papers in six databases: Ovid Medline, Ovid Embase, CENTRAL, CINAHL, PsycArticles and PsycINFO. A narrative synthesis was used to summarise the results.

RESULTS

Twenty-nine articles reporting on 21 healthy ageing interventions (studies) were included in the review. The findings show that a wide range of approaches to implementation were used including collaborative partnership, co-design, use of volunteers, person centred-care, and self-directed/professional-led approaches. The key implementation drivers were the use of behavioural change techniques, social interaction, tailoring of interventions, booster sessions, and multi-component and multi-professional team approach to intervention design and delivery.

CONCLUSION

The effectiveness of healthy ageing interventions is contingent on a number of factors including the type of implementation approaches used, the context in which programs are implemented, and the specific mechanisms that may be at play at the individual older adult level.

Association between Pre-Intervention Physical Activity Level and Treatment Response to Exercise Therapy in Persons with Knee Osteoarthritis - An Exploratory Study

Objective

Examine whether pre‐intervention physical activity (PA) level is associated with achieving a positive treatment response of pain and/or function improvement after a 12‐week exercise intervention in participants with knee osteoarthritis (OA).

Methods

We performed a secondary analysis of a randomized, single‐blind comparative effectiveness trial showing similar treatment effects between Tai Chi mind‐body exercise and standard physical therapy intervention for knee OA. Baseline PA was assessed by a Community Healthy Activities Model Program for Seniors (CHAMPS) questionnaire and, in a subsample, by tri‐axial accelerometers. The Outcome Measures in Rheumatoid Arthritis Clinical Trials–Osteoarthritis Research Society International (OMERACT‐OARSI) dichotomous responder criteria was used for clinically meaningful improvement at follow‐up. Associations between baseline self‐reported PA by the CHAMPS questionnaire and outcomes of responders vs. nonresponders (reference group) were assessed using logistic regressions, adjusting for demographic covariates. We compared objectively measured PA by accelerometry between responders vs. nonresponders using Wilcoxon tests.

Results

Our sample consisted of 166 participants with knee OA who completed both baseline and 12‐week postintervention evaluations: mean age 60.7 year (SD 10.5), body mass index 32.4 kg/m² (6.9), 119 (72%) women, and 138 (83%) OMERACT‐OARSI responders. Neither time spent in total PA [odds ratio (OR) 1.00; 95% confidence interval (CI) 0.96, 1.03] nor time in moderate‐to‐vigorous PA (OR 1.01; 95% CI 0.93, 1.09) at pre‐intervention were associated with being a responder. Similar findings were observed in 42 accelerometry sub‐cohort participants.

Conclusion

Pre‐intervention PA levels (subjective report or objective measurement) were not associated with individuals achieving favorable treatment outcomes after a 12‐week exercise intervention, which suggests that regardless of pre‐intervention PA level, individuals will likely benefit from structured exercise interventions.

The Effects of Preventive Home Visits on Older People’s Use of Health Care and Social Services and Related Costs

Background

We use data from a randomized controlled trial on preventive home visits exploring effectiveness on health-related quality of life. In this article, we examine the intervention’s cost-effectiveness and effects on quality-adjusted life years in older home-dwelling adults.

Methods

There were 422 independently home-dwelling participants in the randomized, controlled trial, all aged more than 75 years, with equal numbers in the control and intervention groups. The intervention took place in a municipality in Finland and consisted of multiprofessional preventive home visits. We gathered the data on health care and social services use from central registers and medical records during 1 year before the intervention and 2 years after the intervention. We analyzed the total health care and social services use and costs per person-years and the difference in change in health-related quality of life as measured using the 15D measure. We calculated quality-adjusted life years and incremental cost-effectiveness ratios.

Results

There was no significant difference in baseline use of services or in the total use and costs of health care and social services during the 2-year follow-up between the two groups. In the intervention group, health-related quality of life declined significantly more slowly compared with the control group (–0.015), but there was no significant difference in quality-adjusted life years gained between the groups. The cost-effectiveness plane showed 60% of incremental cost-effectiveness ratios lying in the dominant quadrant, representing additional effects with lower costs.

Conclusions

This multiprofessional preventive home visit intervention appears to have positive effects on health-related quality of life without accruing additional costs.
