Implementing the access and waiting time standard for early intervention in psychosis in the United Kingdom: An evaluation of referrals and post-assessment outcomes over the first year of operation.

Aim: Improving timely access to evidence-based treatment for people aged 14-65 years experiencing a first episode psychosis (FEP) or an at-risk mental state (ARMS) for psychosis is a national priority within the United Kingdom. An early intervention in psychosis (EIP) access and waiting time standard has been set which has extended the age range and acceptance criteria for services.

Methods: This descriptive evaluation reports upon the referrals and access to treatment times within an EIP service over the first year of operating in line with the access and waiting time standard.
