Background: Paliperidone palmitate (Invega Trinza) is currently the only 3-monthly antipsychotic formulation approved for the treatment of schizophrenia. While clinical trials have demonstrated successful results, post-marketing data is limited.

Objectives: To assess rates of successful transition to the 3-monthly paliperidone injection, while exploring whether the longer dosing interval has an effect on consumer contact with mental health clinicians.

Methods: Community mental health consumers initiated on the 3-monthly paliperidone injection were followed for 6 months following their first 3-monthly injection.  Successful transition was defined as transition to the 3-monthly injection without one or more of the following events occurring within 6 months: hospital admission, additional or increased supplemental antipsychotic therapy, or change or cessation of the 3-monthly injection.

Findings: During the 6 months post transition 41 of 65 (63.1%) consumers successfully transitioned to the 3-monthly injection. Hospital admission was required for 8 (12.3%) consumers and 12 (18.5%) required increased or new antipsychotic supplementation. The 3-monthly injection was discontinued in 11 (16.9%) consumers including 7 (10.8%) who returned to the 1-monthly preparation. Consumers had fewer mean face-to-face contacts with clinicians compared to the 6 months prior to transition (8.2 vs 11.1, p<0.001). This was true for both medical (1.8 vs 2.3, p=0.01) and non-medical contacts (6.4 vs 8.8, p<0.01).

Conclusions: Challenges may be present when transitioning to a long acting antipsychotic injection with a longer dosing interval in a real world setting.  Dissemination of these findings to multi-disciplinary community teams is anticipated to increase purposeful engagement with consumers during this transition period.
