Chair-based yoga programme for older adults with multimorbidity: RCT with embedded economic and process evaluations.

ABSTRACT

Background: Older adults with multimorbidity experience impaired health-related quality of life and treatment burden. Yoga has the potential to improve several aspects of health and well-being. The British Wheel of Yoga's Gentle Years Yoga© programme was developed specifically for older adults, including those with chronic conditions. A pilot trial demonstrated feasibility of using Gentle Years Yoga in this population, but there was limited evidence of its effectiveness and cost-effectiveness. Objective: To determine the effectiveness and cost-effectiveness of the Gentle Years Yoga programme in addition to usual care versus usual care alone in older adults with multimorbidity. Design: Pragmatic, multisite, individually randomised controlled trial with embedded economic and process evaluations. Setting: Participants were recruited from 15 general practices in England and Wales from July 2019 with final follow-up in October 2022. Participants: Community-dwelling adults aged 65 years and over with multimorbidity, defined as two or more chronic health conditions from a predefined list. Interventions: All participants continued with any usual care provided by primary, secondary, community and social services. The intervention group was offered a 12-week programme of Gentle Years Yoga. Main outcome measures: The primary outcome and end point were health-related quality of life measured using the EuroQol-5 Dimensions, five-level version utility index score over 12 months. Secondary outcomes were health-related quality of life, depression, anxiety, loneliness, incidence of falls, adverse events and healthcare resource use. Results: The mean age of the 454 randomised participants was 73.5 years; 60.6% were female, and participants had a median of three chronic conditions. The primary analysis included 422 participants (intervention, n = 227 of 240, 94.6%; usual care, n = 195 of 214, 91.1%). There was no statistically or clinically significant difference in the EuroQol-5 Dimensions, five-level version utility index score over 12 months the predicted mean score for the intervention group was 0.729 (95% confidence interval 0.712 to 0.747) and for usual care it was 0.710 [95% confidence interval (CI) 0.691 to 0.729], with an adjusted mean difference of 0.020 favouring intervention (95% CI -0.006 to 0.045, p = 0.14). No statistically significant differences were observed in secondary outcomes, except for the pain items of the Patient-Reported Outcomes Measurement Information System-29. No serious, related adverse events were reported. The intervention cost £80.85 more per participant (95% CI £76.73 to £84.97) than usual care, generated an additional 0.0178 quality-adjusted life-years per participant (95% CI 0.0175 to 0.0180) and had a 79% probability of being cost-effective at the National Institute for Health and Care Excellence threshold of £20,000 per quality-adjusted life-year gained. The intervention was acceptable to participants, with seven courses delivered face to face and 12 online. Limitations: Self-reported outcome data raise the potential for bias in an unblinded trial. The COVID-19 pandemic affected recruitment, follow-up and the mode of intervention delivery. Conclusions: Although the Gentle Years Yoga programme was not associated with any statistically significant benefits in terms of health-related quality of life, mental health, loneliness or falls, the intervention was safe, acceptable to most participants and highly valued by some. The economic evaluation suggests that the intervention could be cost-effective. Future work Longer-term cost-effectiveness modelling and identifying subgroups of people who are most likely to benefit from this type of intervention.

It is common for older adults to have two or more long-term health conditions. These conditions affect quality of life differently, with some people feeling well and others needing healthcare support. The Gentle Years Yoga programme was developed to improve quality of life for older adults, including those with long-term health conditions. We wanted to see how well the programme worked and if it offered good value for money for the NHS. We tested whether offering a 12-week course of Gentle Years Yoga improved the quality of life and reduced anxiety, depression, loneliness and falls for people aged 65 years and over who had two or more long-term health conditions. We recruited 454 people through general practices across England and Wales, with 240 people selected at random to be invited to take part in the Gentle Years Yoga programme and the other 214 to continue with their usual care and not be offered Gentle Years Yoga. The average age of participants was 74 years, nearly two-thirds were female and the number of long-term health conditions participants had ranged from two to nine (average was three). They completed four questionnaires over a 12-month period. We also interviewed some of the participants and the yoga teachers to find out how the approach worked in practice. The yoga was delivered either face to face or online. We did not find any significant benefits in terms of quality of life, anxiety, depression, loneliness or falls. At interview, some yoga participants noted no or a modest impact on their health or lifestyle, while others described Gentle Years Yoga as transformative, having substantial impacts and improvements on their physical health and emotional well-being. Because running the yoga classes was relatively inexpensive and some insignificant benefits were seen, the Gentle Years Yoga programme may be good value for money.
