概括
基于社区的暴露前预防 (PrEP) 提供显著增加了赞比亚关键人群的吸收率. 这种方法成功地接触到有艾滋病毒感染风险的个体,增强了传统卫生设施之外的预防工作.
科学领域:
- 公共卫生干预 公共卫生干预
- 艾滋病毒预防策略 预防策略
- 计划 科学 实施 计划 科学 实施
背景情况:
- 为预防艾滋病毒,优化暴露前预防 (PrEP) 的采用仍然是一个挑战,特别是在关键人群 (KPs) 中,如与男性发生性关系的男性 (MSM),女性性工作者 (FSW),跨性别者 (TG) 和注射毒品的人 (PWID).
- 传统的基于设施的服务往往难以接触到这些弱势群体,需要创新的交付模式.
- 赞比亚传染病研究中心 (CIDRZ) 旨在扩大PrEP的提供规模,并解决赞比亚卢萨卡的获取不平等问题.
研究的目的:
- 描述CIDRZ使用的程序科学方法,在赞比亚卢萨卡的关键人群中扩大PrEP的提供规模.
- 评估基于社区的干预对PrEP采用,延续和公平性的影响.
- 证明将艾滋病毒预防服务分散到社区场所的有效性.
主要方法:
- 与10个当地KP民间社会组织 (CSO) 和卫生部 (MOH) 建立了合作伙伴关系,在社区安全空间提供艾滋病毒服务.
- 在2021年12月推出了一项以社区为基础的干预措施,在KPs经常到访的社交场所提供PrEP.
- 从2019年9月到2023年6月的例行计划数据使用描述性统计数据和中断时间序列回归来收集和分析,以评估对PrEP吸收,延续和公平性的干预影响.
主要成果:
- 超过38000名受益者获得了艾滋病毒预防服务,67%通过社区机构获得了艾滋病毒预防服务.
- 在接受测试的人中,15,508人 (65.9%) 是艾滋病毒阴性且有资格接受PrEP,其中15,241人 (98.3%) 开始接受PrEP.
- 基于场所的PrEP输送显著增加了PrEP吸收 (98.7%的干预后与96.5%的干预前) 和启动的次数,尽管6个月内PrEP延续率保持不变 (约47%).
结论:
- 将艾滋病毒预防服务分散到社区场所和安全空间,与KP CSOs合作,使成功的社区 PrEP 交付成为可能.
- 这种程序科学方法有效地扩大了PrEP服务的覆盖范围,超出了传统的设施基础设置.

Community Based Intervention
129
Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Observational Studies
10.3K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Study Designs in Epidemiology
561
Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and...
