Resum:	Little is known about the long-term changes in the functioning of schizophrenia patients receiving maintenance therapy with olanzapine long-acting injection (LAI), and whether observed changes differ from those seen with oral olanzapine. This study describes changes in the levels of functioning among outpatients with schizophrenia treated with olanzapine-LAI compared with oral olanzapine over 2 years. This was a secondary analysis of data from a multicenter, randomized, open-label, 2-year study comparing the long-term treatment effectiveness of monthly olanzapine-LAI (405 mg/4 weeks; n=264) with daily oral olanzapine (10 mg/day; n=260). Levels of functioning were assessed with the Heinrichs-Carpenter Quality of Life Scale. Functional status was also classified as "good", "moderate", or "poor", using a previous data-driven approach. Changes in functional levels were assessed with McNemar's test and comparisons between olanzapine-LAI and oral olanzapine employed the Student's t -test. Over the 2-year study, the patients treated with olanzapine-LAI improved their level of functioning (per Quality of Life total score) from 64. 0-70. 8 (P <0. 001). Patients on oral olanzapine also increased their level of functioning from 62. 1-70. 1 (P <0. 001). At baseline, 19. 2% of the olanzapine-LAI-treated patients had a "good" level of functioning, which increased to 27. 5% (P <0. 05). The figures for oral olanzapine were 14. 2% and 24. 5%, respectively (P <0. 001). Results did not significantly differ between olanzapine-LAI and oral olanzapine. In this 2-year, open-label, randomized study of olanzapine-LAI, outpatients with schizophrenia maintained or improved their favorable baseline level of functioning over time. Results did not significantly differ between olanzapine-LAI and oral olanzapine.
