It is estimated that about 1 712 000 people are suffering from disability in Switzerland, and that 1 to 3% of them present a severe form of disability associated with intellectual deficiency. Management of such patients is complex and faces various challenges. Communication and collaboration with the patients and among all stakeholders are key. In this review, we highlight the value of creating a network supporting people with disabilities. We also present the network available for in- and outpatients in Geneva, which offers consultations and training courses for healthcare workers, and encourages coordination between institutions and network collaboration.
