Overview
People diagnosed with primary brain tumours often experience significant symptoms such as fatigue, cognitive changes, anxiety, and reduced ability to carry out everyday activities. These symptoms may be related to the tumour itself or to ongoing systemic anti-cancer treatment. In Ireland, access to structured rehabilitation and symptom management programmes for this population is limited.
The OT SMILE study is evaluating whether a structured occupational therapy-led group programme can improve quality of life and daily functioning in adults with primary brain tumours receiving active treatment.
Participants attending Beaumont Hospital who meet eligibility criteria and provide informed consent will be randomly assigned (like flipping a coin) to one of two groups:
A six-week occupational therapy group programme (OT SMILE), or
Usual care, consisting of written lifestyle management information.
The OT SMILE programme consists of six weekly 90-minute group sessions delivered by occupational therapists. Sessions focus on fatigue management, activity modification, cognitive strategies, relaxation techniques, goal setting, exercise, nutrition, and peer support.
Participants in both groups will complete questionnaires before the programme begins and again after six weeks. These questionnaires measure quality of life, fatigue, and daily functioning.
The main goal of the study is to determine whether the occupational therapy group programme improves health-related quality of life compared to usual care. The results may help inform supportive care services for people living with primary brain tumours.
Description
Background and Rationale
Primary brain tumour patients frequently experience substantial symptom burden, including fatigue, cognitive dysfunction, neurological deficits, emotional distress, and reduced participation in activities of daily living. These symptoms may arise from tumour-related pathology, surgical intervention, radiotherapy, chemotherapy, or systemic anti-cancer treatment (SACT). Functional decline significantly impacts independence and health-related quality of life.
Although rehabilitation interventions have demonstrated benefits in broader oncology populations, there is limited evidence specifically addressing structured occupational therapy (OT)-led group interventions for patients with primary brain tumours, particularly in an Irish healthcare setting.
Occupational therapy focuses on enabling participation in meaningful daily activities through structured goal setting, fatigue management strategies, activity modification, cognitive compensation techniques, and behavioural self-management approaches. Group-based interventions may provide additional benefits including peer support, shared problem-solving, and enhanced motivation.
The OT SMILE study is designed to evaluate the effectiveness of a structured OT-led group intervention in improving health-related quality of life and symptom management among outpatients with primary brain tumours undergoing active systemic treatment.
Study Design
This is a single-centre, prospective, open-label, parallel-group randomised controlled trial conducted at Beaumont Hospital.
Participants will be randomised in a 1:1 ratio to either:
OT SMILE intervention group
Usual care control group
Randomisation will be computer-generated by an independent researcher not involved in recruitment or intervention delivery. Due to the behavioural nature of the intervention, blinding of participants and therapists is not feasible.
Intervention
The OT SMILE programme consists of six weekly group sessions, each lasting approximately 90 minutes, delivered by registered occupational therapists. Groups will include approximately 6-8 participants per cohort.
Session components include:
Education regarding common symptoms in primary brain tumour patients
Fatigue management strategies
Goal setting and activity pacing
Relaxation techniques
Cognitive strategies to support daily functioning
Exercise and physical activity guidance
Nutrition education
Peer support and shared problem-solving
Strategies for habit formation and long-term self-management
Participants in the control group will receive standard written lifestyle management information and continue usual oncology care.
Outcome Assessment
Outcome measures will be collected at baseline and at completion of the six-week intervention period.
The primary outcome is change in health-related quality of life measured using the Functional Assessment of Cancer Therapy - Brain (FACT-BR).
Secondary outcomes include fatigue severity (Brief Fatigue Inventory) and health utility/quality of life (EQ-5D-5L). Occupational performance and satisfaction (Canadian Occupational Performance Measure) will also be assessed in the intervention group.
