The objective of this study was to examine the cost effectiveness of fluvoxamine compared with tricyclic antidepressants (TCAs) in the treatment of patients with depressive episodes.
A Markov process model was constructed to model the effectiveness, as measured by time without depression, and the costs of both treatments. The model examined a period of 18 months in order to capture the influence of both relapses and recurrences on the outcomes. Data for the construction of the model came from the published literature, an expert panel and a large multicentre randomised clinical trial. Costs were obtained from published sources. The setting for this study was France.
The results of the baseline analysis showed that the use of fluvoxamine in the maintenance treatment (recurrence prevention) of depressive disorders was less costly than TCAs with total costs (direct and indirect costs) of 40,232.40 French francs (FF) and FF52,257.53, respectively (1996 values). In addition, due to the prevention of relapse and recurrence, effectiveness favoured fluvoxamine as it was associated with a longer period of time without depression when compared with TCAs (79% of the study period vs 71%). Sensitivity analyses confirmed the robustness of these findings.
In conclusion, on the basis of the assumptions used in the model, the use of fluvoxamine as maintenance therapy is clinically and economically justified in patients with depressive disorders.
本研究的目的是检验氟伏沙明与三环类抗抑郁药(TCA)相比在治疗抑郁发作患者中的成本效益。
构建了一个马尔可夫过程模型来模拟两种治疗方法的有效性(以无抑郁时间衡量)和成本。该模型考察了18个月的时间段,以捕捉复发和再发对结果的影响。构建模型的数据来自已发表的文献、一个专家小组和一项大型多中心随机临床试验。成本从已发表的资料中获取。本研究的背景是法国。
基线分析结果显示,在抑郁症维持治疗(预防复发)中使用氟伏沙明的成本低于三环类抗抑郁药,总成本(直接和间接成本)分别为40232.40法国法郎(FF)和52257.53法国法郎(1996年价值)。此外,由于预防了复发和再发,氟伏沙明在有效性方面更具优势,因为与三环类抗抑郁药相比,它与更长的无抑郁时间相关(分别为研究期的79%和71%)。敏感性分析证实了这些发现的稳健性。
总之,基于模型中使用的假设,对于抑郁症患者,使用氟伏沙明作为维持治疗在临床和经济上是合理的。
