Abstract
Objectives
To determine the incremental cost-utility ratio (ICUR) and incremental cost-effectiveness ratio (ICER) of paliperidone palmitate in the maintenance phase of schizophrenia compared to other antipsychotics available in Colombia.
Methods
Cost-utility and Cost-Effectiveness analysis, from the perspective of the third-party payer, considering the quality-adjusted life-years (QALYs) and avoided relapses, respectively, with the use of paliperidone palmitate long-acting injection (LAI). A Markov model was used over a time horizon of five years. The selection of the initial and alternative treatment was determined from a literature review, patterns of use of antipsychotics in five psychiatric centers in Colombia, and the recommendations of medical experts consulted through an advisory board. The selected alternatives were: paliperidone palmitate LAI, quetiapine oral, risperidone LAI, olanzapine oral and risperidone oral. Direct medical costs were considered: antipsychotic therapy, support and medical monitoring, handling crisis and relapse or subsequent treatment phases (what is meant by lines?). A sensitivity analysis on prices and the key variables (Average length of stay per hospitalization, adherence, risk of relapse of the model was) performed.
Results
The expected costs of care (USD) were: $11.411 with paliperidone palmitate LAI, $8.491 with quetiapine oral, $4.367 with olanzapine oral, $5.540 with risperidone oral and $12.623 with risperidone LAI. The ICUR of paliperidone palmitate was, expressed in USD per QALY, $18.349 compared to quetiapine oral; $36.677 compared to olanzapine oral; $21.970 compared to risperidone oral and dominant in relation to risperidone LAI. The ICERs of paliperidone palmitate were expressed in USD per relapse avoided, $5.682, $18.057, $7.837 and dominant, compared to quetiapine oral, olanzapine oral, risperidone oral and risperidone LAI, respectively. The results showed a reduction in total relapses.
Conclusions
The treatment of schizophrenia during the maintenance phase with paliperidone palmitate, presents a lower expected cost than that obtained with risperidone LAI and increased QALYs.
