Introduction

First-Episode Psychosis (FEP) is a variable condition, characterized by the emergence of new psychotic features for a period of at least 1 week. The majority of existing studies about FEP only address schizophrenia spectrum psychosis (SSP), which may limit the capacity to fully characterize this entity.

Objectives/Aims

Report the clinical and socio-demographic characteristics of patients with FEP in real-world setting, and compare the differences among SSP and affective FEP.

Methods

Retrospective analysis of clinical files of patients admitted to our hospital unit with FEP diagnosis from January/2012 to April/2015. Clinician-rated dimensions of psychosis symptom severity scales (DSM-5) were applied.

Results

Annual incidence of FEP was 11,3/100,000. From a total of 755 patients, 57 (7,5%) corresponded to FEP; 38 (66,7%) were diagnosed with SSP, 11 (19,3%) affective psychosis, 3 (5,2%) toxic psychosis and 5 (8,8%) organic psychosis. Most were female (61,4%), with a mean age of 49 years. The majority were unemployed (66,7%), lived with family (57,9%), and presented with moderate-severe delusions (80,1%), but without hallucinations (57,8%), disorganized speech (59,6%) or negative symptoms (85,9%). Affective FEP patients were older (61 vs 45 years), presented with less severe psychotic symptoms (7,2 vs 8,3 points), but with higher hospital admission (26,1 vs 21,1 days).

Conclusions

Regardless the growing interest concerning FEP, its conceptualization and characterization remains controversial. Our results differ from pre-existing literature data, especially concerning gender and age. By including all the possible etiologies of FEP, we aimed to obtain a more realistic characterization of this entity in a real-world setting.
