Assessing health-related quality-of-life in Australian Multiple Sclerosis Longitudinal Study participants using six multi-attribute utility instruments: implications for healthcare decision-making

Background: Despite important discoveries/advances in treating multiple sclerosis (MS), people with MS (pwMS) can experience delays in accessing new treatments if decision-makers lack robust health economic evidence including health-related quality-of-life (HRQoL) benefits of the intervention. Health state utilities (HSU) are a HRQoL input for cost-utility analysis. Objective(s): Several multi-attribute utility instruments (MAUIs) are available from which HSUs can be derived, but the most appropriate MAUI for use in MS has not been identified. We aimed to determine the preferentially sensitive MAUI(s) that capture the full impact of MS on HRQoL. Method(s): Participants in this study came from a comprehensive HRQoL survey (mid-2020) of the Australian MS Longitudinal Study. The survey included six MAUIs (EQ-5D-5L/ EQ-5D5LPsychosocial, SF-6D versions 1 and 2, AQoL-8D and PropR), and sociodemographic, Covid19-related and subjective wellbeing data. HSUs were generated from Australian value sets. Ceiling and floor effects were investigated. Bland-Altman plots and Shannon's Indices were examined. Minimal important differences and population norms were sourced from the literature. Result(s): N=1,683 pwMS completed the survey (67% response). HSUs were derived for >97% of respondents. Mean age 58.6 years, 80% female, 19% reported severe disease and 63% had relapsing-remitting MS. Mean (SD) HSUs ranged from 0.45+/-0.29 (SF-6Dv1) to 0.63+/-0.22 (AQoL-8D). EQ-5D-5L revealed the highest ceiling (HSU=1.0;n=157,10%) and floor (HSU<=0;n=113,7%) effects. PwMS with EQ-5D-5L HSU<=0/HSU=1 reported mean HSUs of 0.37/0.91, 0.35/0.90, and 0.08/0.85 for the AQoL-8D, EQ-5D5LPsychosocial and SF-6D, respectively. Conclusion(s): While the EQ-5D is the most commonly cited MAUI (in 85% of health technology assessment guidelines), our preliminary comparison results suggest the EQ-5D-5L is not preferentially sensitive in assessing the complex HRQoL domains for pwMS.

Incentivising public transport use for physical activity gain: process evaluation of the COVID-19 disrupted trips4health randomised controlled trial.

BACKGROUND: Partnering with a public transport (PT) provider, state government, and local government, the single-blinded randomised controlled trial, trips4health, investigated the impact of PT use incentives on transport-related physical activity (PA) in Tasmania, Australia. The intervention involved 16-weeks of incentives (bus trip credits) for achieving weekly PT use targets, supported by weekly text messages. This study objective was to conduct a process evaluation of the COVID-19 disrupted trips4health study. METHODS: The Medical Research Council UK's framework for complex public health interventions guided the process evaluation. Participant reach, acceptability, fidelity and feasibility were evaluated. Administrative and post-intervention survey data were analysed descriptively. Semi-structured interviews with intervention participants (n = 7) and PT provider staff (n = 4) were analysed thematically. RESULTS: Due to COVID-19, trips4health was placed on hold (March 2020) then stopped (May 2020) as social restrictions impacted PT use. At study cessation, 116 participants (approximately one third of target sample) had completed baseline measures, 110 were randomised, and 64 (n = 29 in the intervention group; n = 35 in the control group) completed post-intervention measures. Participants were 18 - 80 years (average 44.5 years) with females (69%) and those with tertiary education (55%) over-represented. The intervention was delivered with high fidelity with 96% of bus trip credits and 99% of behavioural text messages sent as intended. Interviewed PT staff said implementation was highly feasible. Intervention participant acceptability was high with 90% reporting bus trip incentives were helpful and 59% reporting the incentives motivated them to use PT more. From a total of 666 possible bus trip targets, 56% were met with 38% of intervention participants agreeing and 41% disagreeing that 'Meeting the bus trip targets was easy'. Interviews and open-ended survey responses from intervention participants revealed incentives motivated bus use but social (e.g., household member commitments) and systemic (e.g., bus availability) factors made meeting bus trip targets challenging. CONCLUSIONS: trips4health demonstrated good acceptability and strong fidelity and feasibility. Future intervention studies incentivising PT use will need to ensure a broader demographic is reached and include more supports to meet PT targets. TRIAL REGISTRATION: ACTRN12619001136190 .

COVID-19 responses: Food policy councils are "stepping in, stepping up, and stepping back"

In the wake of the COVID-19 pandemic, food policy councils (FPCs) have emerged as a critical structure for organizing community-based responses to multiple food system issues. Strong relationships with various food system stakeholders have proven essential in inspiring coordinated action. Using the early results of a Johns Hopkins Center for a Livable Future survey of FPCs (2020), we discuss some of the accomplishments and contributions that 118 FPCs have made toward addressing hunger and supporting producers, school food, food chain workers, racial equity, and resilience in the United States and in tribal nations.
