ABSTRACT
Aim
To develop and describe the implementation and early outcomes of a stepped, transdiagnostic early intervention service (FIPP) for individuals aged 17–30, and to evaluate changes in access, age profile, length of stay, diagnostic mix and community engagement between 2016 and 2024.
Methods
The Jean Wier outpatient centre is part of the public mental health hospital Érasme, which is part of the GHT PsySudParis group in the metropolis of greater Paris (France). Data and surveys showed a treatment gap in service delivery for young people with emerging psychiatric disorders. A comprehensive reorganisation of mental health services was initiated. Developmental aims were training professionals, service establishment and introducing standardised assessment. Evaluation aims were shifts in access, length of stay and diagnostic distribution.
Results
The results show an improved healthcare provision by better trained teams, increased community engagement, a diminished average age of service users, a decreased average length of stay and a diagnostic shift in the day-care program (CARE). Duration of untreated psychosis and disengagement have not yet been objectified.
Conclusions
A proactive, structured and collaborative approach in public mental health care can enhance access to early psychiatric care for young adults in France.
