Abstract
Objectives
The aim the study was to calculate remission, recovery and relapse rates in first episode patients with schizophrenia (FES) vs. patients at a later phase (non-FES).
Methods
Thirty two FES and 101 non-FES patients took part in the study. The assessment included testing at baseline and at 1 year with the PANSS, Calgary Depression scale, STAI, UKU, Simpson Angus and GAF. The statistical analysis included Chi-square test and Analysis of Covariance
Results
At baseline 15.62% FES vs. 10.89% non-FES patients were in remission; none of FES vs. 2.97% non-FES patients were in recovery. At endpoint, the respective figures were 12.50% vs. 25.00% and 3.12% vs. 3.96%. None of the differences in rates was significant between the two groups except from the percentage of patients being under medication (higher in the non-FES group). Baseline PANSS-N was the only predictor of the outcome at endpoint.
Conclusion
The current study reported very low rates of remission and recovery of patients with schizophrenia without any differences between FES and non-FES patients. One possibility is that the increased antipsychotic treatment compensates for the worsening of the illness with time. An accumulating beneficial effect of antipsychotic treatment suggested that early lack of remission is not prognostic of a poor outcome.
