International application of standards for health care quality, access and evaluation of services for early intervention in psychotic disorders.

In the last 4 years, significant progress has been made in the development and application of measures that assess quality and access to evidence-based practices for early intervention in psychosis services. This represents an important step towards providing accountability, improving outcomes and service user experience. The methods used allow for comparison between the services that are assessed with the same methods, but there is a need to compare the different methods. Further research is also required to explore links between quality of care and outcomes for community mental health services that deliver early intervention in psychotic disorders.
