ss=""h4"">Introduction, objectives and aims

To evaluate the outcome of patients with schizophrenia during maintenance treatment with OLAI.

ss=""h4"">Methods

Data from three studies with OLAI were pooled and patients classified according to a cluster analysis [Lipkovich, Psychiatry Res, 2009] into five categories according severity of psychiatric symptoms (sx) and functional impairment (imp):

ss=""listitem"" id=""list_lis0005"">

ss=""label"">A

(minimal sx/mild imp),

ss=""label"">B

(minimal sx/moderate imp),

ss=""label"">C

(moderate sx/mild to moderate imp),

ss=""label"">D

(moderate sx/severe imp),

ss=""label"">E

(moderate to severe sx/severe imp).

Improvement was defined as a change from B or C to A, or from D or E to A, B or C. Changes between the categories in the 6 months were analyzed. Stepwise logistic regression modeling was done to determine factors associated with improvement.

ss=""h4"">Results

1182 patients were classified. Patients who remained in the studies at 6 months had lower baseline CGI-S (3.04 vs 3.28, p < 0.001), lower PANSS (61.38 vs 64.05, p = 0.012) and higher QLS (1.76 vs 1.39, p = 0.001). (Table 1) As patients in category A couldn¡¯t improve and in category D&E couldn¡¯t worsen, 261(39 % ) patients from categories B, C, D and E improved and only 55(10 % ) from categories A, B and C got worse during 6 months. Baseline factors associated with improvement were: baseline category (p < 0.001), CGI-S score (p = 0.022), and PANSS positive (p = 0.003)
