Pre-exposure prophylaxis (PrEP) involves administering antiretroviral drugs to prevent human immunodeficiency virus (HIV) infection in at-risk subjects. Chile is considered one of the countries with the highest number of new cases per year of HIV infections.
A nationwide cross-sectional study was carried out in Chile. A questionnaire of physicians' attitudes toward the prescription of PrEP was used.
632 doctors responded correctly the survey. 58.5% ( = 370) were women, and median age was 34 years (IQR 25-43). 55.4% ( = 350) responded that they have never prescribed antiretrovirals for HIV-negative individuals to prevent HIV infection, and only 10.1% have prescribed PrEP. 60.8% ( = 384) mentioned having informed about the possibility of using antiretroviral post-exposure prophylaxis in case of risky sexual activity. 76.3% ( = 482) believed each institution should formulate internal protocols for administering these drugs, and 98.4% ( = 622) stated that with the currently available evidence, PrEP should be suggested to cope with the HIV pandemic.
It was concluded that knowledge, attitudes and experience toward PrEP prescribing are variable and related to patient care. However, Chile has a marked tendency in favor of this therapy, which is similar to that reported in studies worldwide.
暴露前预防(PrEP)是指对有感染风险的人群给予抗逆转录病毒药物以预防人类免疫缺陷病毒(HIV)感染。智利被认为是每年 HIV 感染新发病例数最高的国家之一。
在智利进行了一项全国性的横断面研究。使用了一份医生对 PrEP 处方态度的调查问卷。
632 名医生正确回答了该调查。58.5%(=370)为女性,中位年龄为 34 岁(IQR 25-43)。55.4%(=350)的医生表示从未为 HIV 阴性个体开具过抗逆转录病毒药物以预防 HIV 感染,只有 10.1%的医生开具过 PrEP。60.8%(=384)的医生提到已告知患者在发生高危性行为时使用抗逆转录病毒暴露后预防的可能性。76.3%(=482)的医生认为每个机构都应制定管理这些药物的内部方案,98.4%(=622)的医生表示,根据目前的证据,应建议使用 PrEP 来应对 HIV 大流行。
研究结果表明,医生对 PrEP 处方的知识、态度和经验存在差异,且与患者护理有关。然而,智利在很大程度上倾向于这种治疗方法,这与全球范围内的研究报告相似。
