Cardiometabolic diseases are prevalent among individuals with psychotic disorders, significantly contributing to their shorter lifespan, reduced quality of life, and economic impact on individuals and society. To improve cardiometabolic health, effective and individualized interventions are crucial. Psychosis outpatient clinics are ideal for these interventions due to regular patient visits and the availability of diverse health professionals. The investigators have developed and want to test a comprehensive intervention program to improve cardiometabolic health, enhance quality of life, and promote healthy lifestyles specifically for people with psychotic disorders at psychiatric outpatient clinics in Gothenburg. This clinical trial aims to include 644 individuals with psychotic disorders from six outpatient clinics in the Department of Psychotic Disorders at Sahlgrenska University Hospital in Gothenburg. Two outpatient clinics will provide the LAGOM-intervention, while the other clinics will serve as controls, offering care as usual. The intervention group will receive multidisciplinary support integrated into the routine clinical procedures. The intervention includes regular follow-ups and use of motivational tools, including body composition analyzer and cardiovascular risk prediction algorithm (QRISK3). If the intervention effectively improves cardiometabolic health, enhances quality of life for this vulnerable group, and proves cost-effective, it can serve as a model program for implementation in Region Västra Götaland.
