Abstract

Introduction: Short-term exposure to antipsychotics has proven to be beneficial. However, naturalistic studies are lacking regarding the long-term use of antipsychotics. This study aimed to investigate changes in use of antipsychotics over 20 years after a first-episode schizophrenia.

Methods: This study is part of the Danish OPUS trial (1998-2000), including 496 participants with first-episode schizophrenia. Participants were reassessed four times over 20 years. The main outcomes were days on medication, redeemed prescriptions of clozapine, psychiatric hospitalizations, and employment.

Results: At the 20-year follow-up, an attrition of 71% was detected. In total, 143 out of 496 participated, with 36% (n = 51) in remission-of-psychotic-symptoms-off-medication. The lowest number of days on medication (mean [s.d.], 339 [538] days) was observed in this group over 20 years. Register data on redeemed antipsychotics were available for all trial participants (n = 416). Individuals in treatment with antipsychotics (n = 120) at the 20-year follow-up had spent significantly more days in treatment (5405 [1857] v. 1434 [1819] mean days, p = 0.00) and more had ever redeemed a prescription of clozapine (25% v. 7.8%, p = 0.00) than individuals who had discontinued antipsychotics (n = 296). Further, discontinuers had significantly higher employment at the 20-year follow-up (28.4% v. 12.5%, p = 0.00).

Conclusion: In a cohort of individuals with first-episode schizophrenia, 36% were in remission-of-psychotic-symptoms-off-medication. However, high attrition was detected, potentially affecting study results by inflating results from individuals with favorable outcomes. From register data, free from attrition, approximately 30% were in treatment with antipsychotics, and 70% had discontinued antipsychotics. Individuals in treatment had the least favorable outcomes, implying greater illness severity.

精神分裂症首次发作后 20 年内抗精神病药物的使用和停药情况:OPUS 试验的结果。
简介事实证明,短期服用抗精神病药物是有益的。然而,有关长期使用抗精神病药物的自然研究却十分缺乏。本研究旨在调查首次出现精神分裂症后 20 年内使用抗精神病药物的变化情况:本研究是丹麦 OPUS 试验(1998-2000 年)的一部分,包括 496 名首发精神分裂症患者。参与者在20年内接受了4次重新评估。主要结果是服药天数、氯氮平处方的兑换情况、精神病住院情况和就业情况:结果:在 20 年的随访中,发现有 71% 的患者流失。在 496 人中,共有 143 人参与,其中 36%(n = 51)的人在停药后精神症状得到缓解。据观察,20 年来,该组患者的服药天数最少(平均[s.d.]为 339 [538] 天)。所有试验参与者(n = 416)都有关于已兑换抗精神病药物的登记数据。在20年的随访中,接受抗精神病药物治疗的患者(n = 120)与停用抗精神病药物的患者(n = 296)相比,接受治疗的天数(5405 [1857] 天v. 1434 [1819] 天的平均值,p = 0.00)明显较多(25%v. 7.8%,p = 0.00),而且有更多的患者曾经兑换过氯氮平处方。此外,在20年的随访中,停药者的就业率明显更高(28.4%对12.5%,P = 0.00):结论:在一组首发精神分裂症患者中,有36%的人在停药后精神症状得到缓解。然而,研究人员发现,减员率很高,这可能会影响研究结果,因为减员率高会夸大结果良好的患者的研究结果。从登记数据来看,在没有自然减员的情况下,约有 30% 的患者正在接受抗精神病药物治疗,70% 的患者已停用抗精神病药物。正在接受治疗的患者的疗效最差,这意味着他们的病情更为严重。
