<< Background >>Good oral health is an essential part of people’s general health and contributes to well-being and quality of life. Still oral diseases are a major health problem in Europe, especially for vulnerable patient groups, such as frail older people, people with severe mental illness, and people with an intellectual disability. These patient groups require special consideration when receiving oral care, such as specialized knowledge and skills, increased awareness and attention, adaptation, and accommodative measures beyond what is considered routine. Research shows that oral care professionals, nursing professionals and social work professionals are lacking the knowledge and skills needed to ensure good oral care for vulnerable patient groups. For oral care professionals, familiarity with the patients’ medical situation and behavioural components are essential to decrease the risk of aggravating a medical condition while rendering oral care. On the other hand, health care professionals (nurses, social workers) should be able to recognize oral diseases and limitations in self-care that form a risk for future oral diseases. The core of this problem can be found at the educational background of healthcare providers. The education is given in a mono-professional approach: oral health students learn about oral healthcare; nursing students learn about general health care provision; students of social work particularly focus on the promotion of psychosocial wellbeing.<< Objectives >>To improve oral healthcare for frail older people, people with severe mental illness and people with an intellectual disability, future oral care professionals and health care professionals need to collaborate more closely and exchange information on a patient’s health situation. In addition, both oral care professionals as well as health care professionals require knowledge and skills regarding medical and psychological conditions, oral health and behavioural aspects of the three vulnerable patient groups.<< Implementation >>The Oral Health Cooperation Partnership project aims to improve oral healthcare for vulnerable patient groups by educating students attending oral health, social work and nurse schools. This two-year project will focus on developing three interprofessional educational modules:1.a module for nursing and social work students on oral health care (2 ECTS);2.a module for oral health students on medical knowledge and mental health necessary to provide care for frail older people, people with severe mental illness, and people with an intellectual disability (2 ECTS);3.a module for oral health, social work and nurse students: students learn to collaborate and to promote oral health of frail older people, people with severe mental illness, and people with an intellectual disability (i.e. developing tailored health intervention and selecting adequate new technologies to foster the interprofessional communication) (4 ECTS).<< Results >>The project will lead to the following outcomes: 1.Inclusion of online interprofessional educational courses within the curricula of European higher educational institutions;2.Improvement of knowledge, skills, and attitude of oral health, nursing and social work students (and after the project duration, also of other health care professionals and family carers);3.Interprofessional and cross-border cooperation in the field of oral health;4.Improvement of oral health promotion among vulnerable patients with specific needs, focusing on prevention, diagnosis, and treatment of oral diseases. Including improvements in oral health behaviour and/or oral health of frail older people, people with severe mental illness, and people with an intellectual disability. 5.Improvement of students skills on applying adequate digital technologies to foster interprofessional collaboration and to promote oral health.
