Evaluating the Effectiveness of the GILL eHealth Intervention to Improve Physical Health and Lifestyle Behaviours in Patients With Severe Mental Illness

Netherlands258 participantsStarted 2024-05-30

Plain-language summary

The aim of this study is to evaluate the effectiveness of the nurse-led GILL (Gezondheid in Lichaam en Leefstijl) eHealth intervention in patients with serious mental illness (SMI), compared to usual care. Expected is that the GILL eHealth intervention will be more effective than usual care in improving physical health and lifestyle behaviors. To evaluate this, we will perform a cluster randomized controlled trial with an embedded process evaluation of the implementation of the GILL intervention. 258 adult patients with serious mental illness and a body mass index of 27 or higher (overweight/obesity) will be included. The GILL eHealth intervention consists of two complementary modules for (a) somatic screening and (b) lifestyle promotion, resulting in a personalized somatic treatment and lifestyle plan. Trained mental health nurses and clinical nurse specialists will implement the intervention within the multidisciplinary treatment context, and will guide and support the patients in the promotion of their somatic health, including cardiometabolic risk management. The intervention will be compared to usual care, which includes treatment according to national guidelines. The outcome measures will be metabolic syndrome severity (primary), fitness, physical activity, lifestyle behaviors, quality of life, recovery, psychosocial functioning, health related self-efficacy and health care utilization after 1 year. The process evaluation focuses on the feasibility of the eHealth intervention, its acceptability for patients and health care providers (mainly mental health nurses and clinical nurse specialists), and barriers/facilitators to implementation.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
