To promote HIV antiretroviral therapy (ART) outcomes in Haiti, we developed a culturally relevant intervention (InfoPlus Adherence) that combines an electronic medical record alert identifying patients at elevated risk of treatment failure and provider-delivered brief problem-solving counseling. We conducted a quasi-experimental mixed-methods study among 146 patients at two large ART clinics in Haiti with 728 historical controls. We conducted quantitative assessments of patients at baseline and intervention completion (6 months) as well as focus groups with health workers and exit interviews with patients. The primary quantitative outcome measures were HIV viral suppression according to medical record and ART adherence in terms of ≥ 90% for "proportion of days covered" (PDC) according to pharmacy dispensing data. Results indicated that the proportion of intervention patients with suppressed VL during the study/historical periods was 80.0%/86.0% and 76.8%/87.4% for controls. In a difference-in-differences (DID) analytic model, the adjusted relative risk for viral suppression with the intervention was 1.15 (95% CI 0.92-1.45, p = 0.21), representing favorable but non-significant association between the intervention and the trajectory of VL outcomes. PDC ≥ 90% during the study/historical periods was 30.9%/11.0% among intervention participants and 16.9%/19.4% among controls. In the adjusted DID model, the relative risk for of PDC ≥ 90% with the intervention was 4.00 (95% CI 1.91-8.38, p < 0.001), representing a highly favorable association between the intervention and the trajectory of PDC outcomes. Qualitative data affirmed acceptability of the intervention, although providers reported some challenges consistently implementing it. Future research is needed to demonstrate efficacy and explore optimal implementation strategies.
为了提高海地的艾滋病毒抗逆转录病毒疗法(ART)效果,我们开发了一种具有文化相关性的干预措施(InfoPlus 遵医嘱治疗),它结合了电子病历警报,识别出处于治疗失败高风险的患者,以及由提供者提供的简短的解决问题的咨询。我们在海地的两家大型 ART 诊所对 146 名患者进行了一项准实验性混合方法研究,其中包括 728 名历史对照。我们在基线和干预完成(6 个月)时对患者进行了定量评估,以及与卫生工作者进行焦点小组讨论,并对患者进行了退出访谈。主要的定量结果测量是根据病历记录评估的 HIV 病毒抑制情况,以及根据药房配药数据评估的 ART 依从性,即 ≥90%的“覆盖日比例”(PDC)。结果表明,在研究/历史期间,干预组中 VL 得到抑制的患者比例为 80.0%/86.0%,对照组为 76.8%/87.4%。在差异分析(DID)分析模型中,干预组的病毒抑制调整后相对风险为 1.15(95%置信区间 0.92-1.45,p=0.21),这表明干预与 VL 结果的轨迹之间存在有利但无显著性关联。在研究/历史期间,PDC≥90%的患者比例分别为干预组的 30.9%/11.0%,对照组的 16.9%/19.4%。在调整后的 DID 模型中,干预组 PDC≥90%的相对风险为 4.00(95%置信区间 1.91-8.38,p<0.001),这表明干预与 PDC 结果的轨迹之间存在高度有利的关联。定性数据证实了干预措施的可接受性,尽管提供者报告了一些实施该措施的挑战。未来需要开展研究来证明其疗效,并探索最佳实施策略。
