Article Synopsis
  • People who have had a stroke are significantly more likely to experience another stroke compared to those who haven't, making it vital to address lifestyle factors like inactivity and poor diet to lower blood pressure and stroke risk.
  • Survivors often face barriers to accessing risk reduction services, such as long wait times and limited transportation, highlighting the need for more accessible solutions, like an online health intervention platform.
  • The i-REBOUND after stroke website was developed using a collaborative approach and design thinking framework, focusing on creating an easy-to-navigate resource tailored to stroke survivors, by adapting existing telehealth programs for better accessibility and support.

Introduction: In-person physiotherapy services are not readily available to all individuals with musculoskeletal conditions, especially those in rural regions or with time-intensive responsibilities. The COVID-19 pandemic highlighted that telehealth may facilitate access to, and continuity of care, yet many physiotherapists lack telehealth confidence and training. This project co-developed and evaluated a web-based professional development toolkit supporting physiotherapists to provide telehealth services for musculoskeletal conditions.

Background: Waiting lists for community-based paediatric therapy services are common and lead to poorer health outcomes, anxiety and missed opportunities for treatment during crucial developmental stages. The Specific Timely Appointments for Triage (STAT) model has been shown to reduce waiting lists in a range of health settings.

Aims: To determine whether providing training and support in the STAT model to champions within five community health centres using a remote 'hub and spoke' approach could reduce waiting time from referral to first appointment.

Lifestyle interventions targeting energy balance (ie, diet, exercise) are critical for optimizing the health and well-being of cancer survivors. Despite their benefits, access to these interventions is limited, especially in underserved populations, including older people, minority populations and those living in rural and remote areas. Telehealth has the potential to improve equity and increase access.

Background: Autologous stem cell transplant is a common procedure for people with haematological malignancies. While effective at improving survival, autologous stem cell transplant recipients may have a lengthy hospital admission and experience debilitating side-effects such as fatigue, pain and deconditioning that may prolong recovery. Prehabilitation comprising exercise and nutrition intervention before stem cell transplant aims to optimise physical capacity before the procedure to enhance functional recovery after transplant.

With colonoscopy resources under pressure and inequitable participation rates in our screening programmes, there is an urgent need to consider trialling new testing technology for the detection of colorectal cancer (CRC) in Australasia. Research has shown that volatile organic compounds (VOCs) emitted from the human body can act as biomarkers for CRC, indicating high sensitivity and specificity for early and late-stage CRC and for adenomatous polyps. Breath-based VOC testing shows promise due to acceptability and ease of sampling via simple hand-held devices.

A large evidence base demonstrates that the outcomes of COVID-19 and national and local interventions are not distributed equally across different communities. The need to inform policies and mitigation measures aimed at reducing the spread of COVID-19 highlights the need to understand the complex links between our daily activities and COVID-19 transmission that reflect the characteristics of British society. As a result of a partnership between academic and private sector researchers, we introduce a novel data driven modelling framework together with a computationally efficient approach to running complex simulation models of this type.
