A 12-dose weekly regimen of rifapentine plus isoniazid (3HP) is recommended for the prevention of active tuberculosis (TB); however, it is unclear whether 3HP should be provided by directly observed therapy (DOT) or self-administered therapy (SAT). In addition, the introduction of patient informed choice between delivery modalities may have a positive impact on factors leading to treatment completion. The authors randomized 252 participants with HIV to a hypothetical scenario of providing preventive therapy by either DOT or an informed choice between DOT and SAT. Out of 104 participants who were randomized to a choice between DOT and SAT, 103 chose therapy by SAT. Participants rated their level of confidence and intention to complete therapy. Compared to those assigned to the DOT scenario, patients assigned to the choice scenario expressed greater confidence and intention to complete preventive therapy. Convenience and travel required to complete 3HP therapy were important factors in deciding between delivery modalities. Those assigned to DOT identified more barriers to completing therapy than those given a choice. Empowering patients to make informed decisions about how they receive TB preventive therapy may improve completion rates.
利福喷丁加异烟肼(3HP)每周 12 剂量方案被推荐用于预防活动性结核病(TB);然而,尚不清楚 3HP 是应该通过直接观察治疗(DOT)还是自我管理治疗(SAT)来提供。此外,在治疗方式的选择上引入患者知情选择可能会对导致治疗完成的因素产生积极影响。作者将 252 名 HIV 阳性参与者随机分配到通过 DOT 或 DOT 和 SAT 之间的知情选择提供预防性治疗的假设情景中。在 104 名被随机分配到 DOT 和 SAT 之间选择的参与者中,有 103 名选择了 SAT 治疗。参与者评估了他们完成治疗的信心水平和意愿。与被分配到 DOT 方案的患者相比,被分配到选择方案的患者对完成预防性治疗的信心和意愿更高。完成 3HP 治疗所需的便利性和旅行是选择治疗方式的重要因素。被分配到 DOT 的患者比那些有选择的患者识别出更多的治疗障碍。赋予患者关于他们接受结核病预防性治疗的方式的知情决策能力可能会提高完成率。
