Development of the digital assessment of precise physical activity (DAPPA) tool for older adults

Physical activity (PA) is central to maintaining health and wellbeing as we age. Valid, reliable measurement tools are vital for understanding, and evaluating PA. There are limited options for comprehensively, accurately and affordably measuring older adults’ PA at scale at present. We aimed to develop a digital PA measurement tool specifically for adults aged 65+ using a person-based approach. We collated evidence from target users, field experts and the relevant literature to learn how older adults comprehend PA and would accept a digital tool. Findings suggest that older adults’ PA is often integrated into their daily life activities and that commonly applied terminology (e.g., moderate and vigorous) can be difficult to interpret. We also found that there is increasing familiarity with digital platforms amongst older adults, and that technological simplicity is valued. These findings informed the development of a digital tool that asks users to report their activities across key PA domains and dimensions from the previous 7-days. Users found the tool easy to navigate and comprehensive in terms of activity reporting. However, real-world usability testing revealed that users struggled with seven-day recall. Further work will address the identified issues, including creating a single-day reporting option, before commencing work to validate this new tool

Internet-Based Vestibular Rehabilitation for Older Adults With Chronic Dizziness: A Randomized Controlled Trial in Primary Care

Purpose: Vestibular Rehabilitation (VR) is an effective intervention for dizziness due to vestibular dysfunction, but is seldom provided. We aimed to determine the effectiveness of internet-based VR for older adults experiencing dizziness in primary care. Methods: A single centre, single blind randomised controlled trial comparing an internet-based VR intervention with usual primary care was conducted with patients from 54 primary care practices in southern England (ISRCTN: 86912968). Patients aged 50 years and over with current dizziness exacerbated by head movements were included in the trial. Patients accessed an automated internet-based intervention that taught VR exercises and suggested cognitive behavioural management strategies. Dizziness was measured by the Vertigo Symptom Scale Short-Form (VSS-SF) at baseline, 3 and 6 months. The primary outcome was VSS-SF score at 6 months. Results: A total of 296 patients were randomized into the trial (66% female, median age 67). The VSS-SF was completed by 250 participants at 3 months (84%: 123 intervention (77%), 127 usual care (93%)) and 230 participants at 6 months (78%: 112 intervention (70%), 118 usual care (87%)). At 3 and 6 months dizziness symptoms were significantly lower in the internet-based VR group compared to usual care (2.75, 95% CI, 1.39 to 4.12; p<0.001 and 2.26, 95% CI, 0.39 to 4.12; p=0.018 respectively). Dizziness-related disability was also significantly lower in the internet-based VR condition, at 3 (6.15 95% CI, 2.81 to 9.49; p<0.001) and 6 month (5.58, 95% CI, 1.19 to 10.0; p=0.013). Conclusions: Internet-based VR improves dizziness and reduces dizziness-based disability in older primary care patients without requiring clinical support, and has potential for wide application in community settings

Implementing a Health Care Professional-Supported Digital Intervention for Survivors of Cancer in Primary Care:Qualitative Process Evaluation of the Renewed Intervention

Background: Primary care has an important role in supporting cancer survivors, yet support is limited because of practitioners’ perceived lack of expertise and time. A digital intervention for cancer survivors could provide an efficient way for primary care staff to support cancer survivors without the need to accumulate expertise and skills to help patients make behaviour changes, providing very brief support alongside this could maximise adherence to the digital interventions. Renewed is a digital intervention combining online behaviour change advice with brief healthcare practitioner support from a nurse or healthcare assistant. Knowledge about the views and experiences of primary care staff providing support alongside a digital intervention for cancer survivors is sparse, limiting understanding of the acceptability and feasibility of this type of intervention. Objective: To explore Supporters’ experiences of providing support to cancer survivors using Renewed, to understand potential barriers and facilitators to implementation of Renewed in practice, and investigate strengths and weaknesses of the intervention from the perspective of healthcare professionals.Methods: This was a qualitative process evaluation, nested within a large trial evaluating Renewed. Twenty-eight semi-structured telephone interviews were conducted with nurses and healthcare assistants. Data were analysed using inductive thematic analysis.Results: Four themes were developed during analysis which reflected factors that Supporters identified as hindering or enabling them to provide support alongside Renewed Online (Themes: Renewed Online as an acceptable digital tool with some improvements; confidence to enact the Supporter role; practicalities of delivering support alongside a digital intervention; and managing a patient-led approach). The analysis suggests that Supporters perceived that a digital intervention such as Renewed would be beneficial to support cancer survivors in primary care, and fit within current practices. However, barriers to providing support alongside a digital intervention were also identified, including concerns about how to facilitate rapport building and, in a minority, concerns about employing a non-directive approach, in which the majority of advice and support is provided through a digital intervention, with brief additional support provided by primary care staff. Conclusion: These findings add to the literature about how best to provide support alongside digital interventions, suggesting that whilst most practitioners cope well with a non-directive approach, a minority require more training to feel confident implementing this. This study suggests that barriers to providing formal support to cancer survivors in primary care could be successfully overcome with an approach like Renewed, where a digital intervention provides most of the support and expertise, and healthcare practitioners provide the additional brief human support to maximise engagement. Strategies to maximise the chances of successful implementation for this type of intervention are discussed. <br/

Internet based vestibular rehabilitation with and without physiotherapy support for adults aged 50 and older with a chronic vestibular syndrome in general practice:three armed randomised controlled trial

Objective: To investigate the clinical effectiveness and safety of stand alone and blended internet based vestibular rehabilitation (VR) in the management of chronic vestibular syndromes in general practice.Design: Pragmatic, three armed, parallel group, individually randomised controlled trial.Setting: 59 general practices in the Netherlands.Participants: 322 adults aged 50 and older with a chronic vestibular syndrome.Interventions: Stand alone VR comprising a six week, internet based intervention with weekly online sessions and daily exercises (10-20 minutes a day). In the blended VR group, the same internet based intervention was supplemented by face-to-face physiotherapy support (home visits in weeks 1 and 3). Participants in the usual care group received standard care from a general practitioner, without any restrictions.Main outcome measures: The primary outcome was vestibular symptoms after six months as measured by the vertigo symptom scale-short form (VSS-SF range 0-60, clinically relevant difference ≥3 points). Secondary outcomes were dizziness related impairment, anxiety, depressive symptoms, subjective improvement of vestibular symptoms after three and six months, and adverse events.Results: In the intention-to-treat analysis, participants in the stand alone and blended VR groups had lower VSS-SF scores at six months than participants in the usual care group (adjusted mean difference −4.1 points, 95% confidence interval −5.8 to −2.5; and −3.5 points, −5.1 to −1.9, respectively). Similar differences in VSS-SF scores were seen at three months follow-up. Participants in the stand alone and blended VR groups also experienced less dizziness related impairment, less anxiety, and more subjective improvement of vestibular symptoms at three and six months. No serious adverse events related to online VR occurred during the trial.Conclusion: Stand alone and blended internet based VR are clinically effective and safe interventions to treat adults aged 50 and older with a chronic vestibular syndrome. Online VR is an easily accessible form of treatment, with the potential to improve care for an undertreated group of patients in general practice.Trial registration: Netherlands Trial Register NTR5712

Planning and optimising a digital intervention to protect older adults' cognitive health.

BackgroundBy 2050, worldwide dementia prevalence is expected to triple. Affordable, scalable interventions are required to support protective behaviours such as physical activity, cognitive training and healthy eating. This paper outlines the theory-, evidence- and person-based development of 'Active Brains': a multi-domain digital behaviour change intervention to reduce cognitive decline amongst older adults.MethodsDuring the initial planning phase, scoping reviews, consultation with PPI contributors and expert co-investigators and behavioural analysis collated and recorded evidence that was triangulated to inform provisional 'guiding principles' and an intervention logic model. The following optimisation phase involved qualitative think aloud and semi-structured interviews with 52 older adults with higher and lower cognitive performance scores. Data were analysed thematically and informed changes and additions to guiding principles, the behavioural analysis and the logic model which, in turn, informed changes to intervention content.ResultsScoping reviews and qualitative interviews suggested that the same intervention content may be suitable for individuals with higher and lower cognitive performance. Qualitative findings revealed that maintaining independence and enjoyment motivated engagement in intervention-targeted behaviours, whereas managing ill health was a potential barrier. Social support for engaging in such activities could provide motivation, but was not desirable for all. These findings informed development of intervention content and functionality that appeared highly acceptable amongst a sample of target users.ConclusionsA digitally delivered intervention with minimal support appears acceptable and potentially engaging to older adults with higher and lower levels of cognitive performance. As well as informing our own intervention development, insights obtained through this process may be useful for others working with, and developing interventions for, older adults and/or those with cognitive impairment

The Active Brains Digital Intervention to Reduce Cognitive Decline in Older Adults: Protocol for a Feasibility Randomized Controlled Trial.

BACKGROUND: Increasing physical activity, improving diet, and performing brain training exercises are associated with reduced cognitive decline in older adults. OBJECTIVE: In this paper, we describe a feasibility trial of the Active Brains intervention, a web-based digital intervention developed to support older adults to make these 3 healthy behavior changes associated with improved cognitive health. The Active Brains trial is a randomized feasibility trial that will test how accessible, acceptable, and feasible the Active Brains intervention is and the effectiveness of the study procedures that we intend to use in the larger, main trial. METHODS: In the randomized controlled trial (RCT), we use a parallel design. We will be conducting the intervention with 2 populations recruited through GP practices (family practices) in England from 2018 to 2019: older adults with signs of cognitive decline and older adults without any cognitive decline. Trial participants were randomly allocated to 1 of 3 study groups: usual care, the Active Brains intervention, or the Active Brains website plus brief support from a trained coach (over the phone or by email). The main outcomes are performance on cognitive tasks, quality of life (using EuroQol-5D 5 level), Instrumental Activities of Daily Living, and diagnoses of dementia. Secondary outcomes (including depression, enablement, and health care costs) and process measures (including qualitative interviews with participants and supporters) will also be collected. The trial has been approved by the National Health Service Research Ethics Committee (reference 17/SC/0463). RESULTS: Results will be published in peer-reviewed journals, presented at conferences, and shared at public engagement events. Data collection was completed in May 2020, and the results will be reported in 2021. CONCLUSIONS: The findings of this study will help us to identify and make important changes to the website, the support received, or the study procedures before we progress to our main randomized phase III trial.

A process evaluation of engagement and outcomes in internet support physical rehabilitation for chronic dizziness

Vestibular-related dizziness is a highly debilitating condition, especially common amongst older adults. It can often be successfully managed with physical therapy exercises known as Vestibular Rehabilitation (VR) but access to VR is very limited. The ‘Balance Retraining’ digital intervention was developed to meet the need for increased availability of this therapy, and a primary-care based Randomised Controlled Trial demonstrated it to be effective. In order to maximise the potential efficacy, reach and acceptability of such interventions, it is important to investigate causal mechanisms and contextual factors. This provides insight how and why outcomes occur under given circumstances, and the underlying psychological mechanisms. This thesis employed quantitative and qualitative methodologies to investigate the processes involved in individuals’ engagement with, and outcomes of, the Balance Retraining intervention. A systematic review of 30 studies investigating predictors of adherence to self-managed physical therapies revealed that self-efficacy, self-motivation, intention, previous adherence behaviour and social support were most consistently associated with adherence. Following this, a qualitative study explored older adults’ experiences of engaging with Balance Retraining over a 6-week period. Participants experienced internet-delivered VR very positively; many were motivated by improvements in their symptoms, but some also found that practical issues, or doubts about the exercises caused difficulties. A quantitative investigation of predictors of change in dizziness severity revealed that adherence-problems, particularly those relating to symptom exacerbation, were especially detrimental for dizziness outcomes and that those who were more anxious or less confident about their ability to complete VR were more susceptible to these. A final mixed methods analysis found that the intervention appeared to operate primarily through addressing adherence problems and that greater overall use, and use of specific features, was beneficial for outcomes. The findings of this thesis provide promising evidence that digitally-delivered VR is acceptable and accessible amongst older adults, and highlight key intervention features and the underlying BCTs that appear instrumental in Balance Retraining’s effectiveness

Predictors of adherence to home-based physical rehabilitation therapies: a systematic review

Purpose: Self-managed, home-based physical therapy (HBPT) is an increasingly common element of physical therapy rehabilitation programmes but non-adherence can reach 70%. Understanding factors that influence patients’ adherence to HBPTs could help practitioners support better adherence. Research to date has focussed largely on clinic-based physiotherapy. The objective of this review, therefore, was to identify specific factors, which influence adherence to home-based, self-managed physical therapies.Method: A systematic review was conducted, in which eight online databases were searched using combinations of key terms relating to physical therapies, adherence and predictors. Matching records were screened against eligibility criteria and 30 quantitative articles were quality assessed and included in the final review. Relevant data were extracted and a narrative synthesis approach was taken to aggregating findings across studies.Results: There was relatively strong evidence that the following factors predicted adherence to HBPTs: intention to engage in the HBPT, self-motivation, self-efficacy, previous adherence to exercise-related behaviours and social support.Conclusions: This review has identified a range of factors that appear to be related to patients’ adherence to their self-managed physical rehabilitation therapies. Awareness of these factors may inform design of interventions to improve adherence

The rapid adaptation and optimisation of a digital behaviour change intervention to reduce the spread of COVID-19 in schools

The rapid transmission of COVID-19 in school communities has been a major concern. To ensure that mitigation systems were in place and support was available, a digital intervention to encourage and facilitate infection-control behaviours was rapidly adapted and optimised for implementation as a whole-school intervention. Using the person-based approach, ‘Germ Defence’ was iteratively adapted, guided by relevant literature, co-production with Patient and Public Involvement representatives, and think-aloud interviews with forty-five school students, staff, and parents. Suggested infection-control behaviours deemed feasible and acceptable by the majority of participants included handwashing/hand-sanitising and wearing a face covering in certain contexts, such as crowded public spaces. Promoting a sense of collective responsibility was reported to increase motivation for the adoption of these behaviours. However, acceptability and willingness to implement recommended behaviours seemed to be influenced by participants’ perceptions of risk. Barriers to the implementation of recommended behaviours in school and at home primarily related to childcare needs and physical space. We conclude that it was possible to rapidly adapt Germ Defence to provide an acceptable resource to help mitigate against infection transmission within and from school settings. Adapted content was considered acceptable, persuasive, and accessible
