The research about the benefits of early diagnosis and treatment of first-episode psychosis had significantly increased in last decades. There have been several early intervention programs in psychotic disease, implemented worldwide, in order to improve the prognosis of these psychotic patients.

To present a brief description of the first-episode psychosis intervention team of Tondela-Viseu Hospital Centre–Portugal and its model. We aim to further characterize our population and describe its evolution since 2008.

We aim to clarify the benefits of an early intervention in psychosis.

We conducted a retrospective cohort study of patients being followed by our team from November 2008 to September 2016. Demographic and medical data were collected (such as diagnosis, duration of untreated psychosis, treatments and its clinical effectiveness, relapse rate and hospital admissions) in patient's clinical records. The intervention model protocol of this team was also described and analyzed.

This multidisciplinary team consists of three psychiatrists, one child Psychiatrist, one psychologist and five reference therapists (areas of nursing, social service and occupational therapy). It includes patients diagnosed with first-episode psychosis, aged 16 to 42 years old, followed for five years. The team followed, since its foundation, 123 patients, mostly male. The most prevalent diagnosis are schizophrenia and schizophreniform psychosis. The team is currently following 51 patients.

This team's intervention have progressively assumed a more relevant importance in the prognosis of patients with first-episode psychosis, by reducing the duration of untreated psychosis, the relapse rate and by promoting social reintegration.
