Rurally located individuals living with hepatitis C virus (HCV) face barriers to engagement and retention in care. Telemedicine technologies coupled with highly curative direct acting antiviral (DAA) treatments may increase accessibility to HCV care while achieving high sustained virologic response (SVR) rates. We compared clinical and socio-economic characteristics, SVR, and loss to follow-up among telemedicine (TM), mixed delivery (MD), and outpatient clinic (OPC) patients receiving care through The Ottawa Hospital Viral Hepatitis Program (TOHVHP).
TOHVHP clinical database was used to evaluate patients engaging HCV care between January 1, 2012, and December 31, 2016. SVR rates by HCV care delivery method (TM versus OPC versus MD) were calculated.
Analysis included 1,454 patients who engaged with TOHVHP at least once. Patients were aged almost 50 years on average and were predominately male and Caucasian. A greater proportion of TM patients were rurally based, were Indigenous, had a history of substance use, and had previously been incarcerated. Per-protocol DAA SVR rates for TM, OPC, and MD patients were 100% (26/26), 93% (440/472), and 94% (44/47), respectively. Loss-to-follow-up rates for HCV-treated TM and MD patients were higher (27% [10/37], 95% CI 0.58 to 0.88, and 11% [7/62], 95% CI 0.81 to 0.97, respectively) than for those followed exclusively in the OPC (5% [39/800], 95% CI 0.94 to 0.97).
TM can successfully engage, retain, and cure rurally based HCV patients facing barriers to care. Strategies to improve TM retention of patients initiating HCV antiviral treatment are key to optimizing the impact of this model of care.
居住在农村地区的丙型肝炎病毒(HCV)感染者在接受治疗及维持治疗方面面临诸多障碍。远程医疗技术与高治愈率的直接抗病毒药物(DAA)治疗相结合,可能会增加HCV治疗的可及性,同时实现较高的持续病毒学应答(SVR)率。我们比较了通过渥太华医院病毒性肝炎项目(TOHVHP)接受治疗的远程医疗(TM)、混合治疗(MD)和门诊患者(OPC)的临床及社会经济特征、SVR情况以及失访情况。
利用TOHVHP临床数据库评估2012年1月1日至2016年12月31日期间接受HCV治疗的患者。计算不同HCV治疗方式(TM与OPC与MD)的SVR率。
分析纳入了至少接受过一次TOHVHP治疗的1454例患者。患者平均年龄近50岁,以男性白种人为主。TM患者中,农村居民、原住民、有药物使用史及曾被监禁的比例更高。TM、OPC和MD患者的按方案DAA SVR率分别为100%(26/26)、93%(440/472)和94%(44/47)。接受HCV治疗的TM和MD患者的失访率(分别为27%[10/37],95%CI 0.58至0.88和11%[7/62],95%CI 0.81至0.97)高于仅在OPC接受治疗的患者(5%[39/800],95%CI 0.94至0.97)。
TM能够成功地使面临治疗障碍的农村HCV患者接受治疗、维持治疗并治愈。改善启动HCV抗病毒治疗患者的TM治疗维持率的策略是优化这种治疗模式效果的关键。
