The goal of this clinical trial is to evaluate whether a novel integrated, multidisciplinary healthcare programme can improve quality of life for adults living with obesity on the island of Ireland.
The main questions it aims to answer are:
* Does participation in the 52-week PEACETIME programme improve participants' quality of life?
* Does the programme improve clinical outcomes, including weight, blood glucose control, and other markers of health?
* Does the programme improve mental health, health empowerment, and self-management?
* Is the programme acceptable to patients and healthcare professionals, and is it cost-effective compared with standard practice?
Participants will receive a 52-week obesity management programme delivered by an interdisciplinary team comprising dietitians, psychologists, physiotherapists, physical activity specialists, nurses, and health coaches. Following a comprehensive assessment by the Multidisciplinary Team, participants will be allocated to one of four personalised care pathways based on their needs, goals, preferences, and clinical complexity: (1) digital health support with a Health Coach; (2) digital health support with additional Multidisciplinary Team input, including online group education and peer support; (3) a centre-based Multidisciplinary Team programme with face-to-face group education and individual support; or (4) a Clinical Psychology pathway including psychological assessment, group-based support, and individual interventions where required. All pathways include ongoing review, early assessment of progress, and maintenance support.
Participants will:
* Attend assessment appointments at the start of the programme (baseline), at approximately 24 weeks, and at 52 weeks.
* Have measurements taken, including weight, blood pressure, physical function, and blood tests where required.
* Complete questionnaires about quality of life, mental health, physical activity, health empowerment, and self-management.
* Receive personalised support through health coaching, group sessions, educational resources, and individual consultations, depending on their allocated pathway.
* Have access to a digital health platform for communication, education, monitoring progress, and attending online appointments where relevant to their pathway.
* Have relevant clinical information collected from their medical records to assess changes in health and healthcare use over time.
Researchers will compare participants' outcomes over the 52-week programme with their baseline measurements to assess changes in quality of life and other health outcomes. There is no comparison group within the main single-arm clinical programme.
