莱索托农村乡村卫生工作者以社区为基础、电子卫生支持的 2 型糖尿病护理 (ComBaCaL DM)
ComBaCaL 队列研究 (ComBaCaL T2D TwiC) 中的集群随机试验协议,以社区为基础,电子健康支持 2 型糖尿病护理由莱索托农村地区的乡村卫生工作者提供
这种整群随机干预纳入了 ComBaCaL(莱索托社区慢性病护理)队列研究 (EKNZ ID AO_2022-00058, clinicaltrials.gov ID NCT05596773,莱索托 NH-REC ID 210-2022),这是一个调查莱索托农村慢性病及其管理的平台,由当地的非专业慢性病护理村卫生工作者 (CC-VHW) 维护。
ComBaCaL 队列研究和嵌套 TwiCs 的总体目标是评估莱索托农村地区电子健康支持的、外行主导的慢性病控制措施的影响。
在此 T2D TwiC 中,与基于设施的护理相比,基于社区的 T2D 护理包(包括由 CC-VHW 为简单的 T2D 提供一线口服抗糖尿病和降脂治疗的效果、安全性和可行性在基于社区的筛查和诊断之后)将进行评估。

详细说明
据估计,2019 年全球有 9.3% 的成年人口或 4.36 亿人患有糖尿病。 到 2045 年,这一数字预计将增加 50% 以上,达到 7 亿多。 五分之四的糖尿病患者目前生活在低收入和中等收入国家 (LMIC)。 超过 90% 的糖尿病病例是由 2 型糖尿病 (T2D) 引起的,这也是预计总体糖尿病病例增加的主要驱动因素。 T2D 患病率的增加是由人口老龄化和生活方式改变引起的,体力活动水平下降,高热量饮食和相关肥胖。
这种整群随机干预纳入了 ComBaCaL(莱索托社区慢性病护理)队列研究 (EKNZ ID AO_2022-00058, clinicaltrials.gov ID NCT05596773,莱索托 NH-REC ID 210-2022),这是一个调查莱索托农村慢性病及其管理的平台,由当地的非专业慢性病护理村卫生工作者 (CC-VHW) 维护。
在该试验中,将使用队列内试验 (TwiCs) 方法分析 LHW 主导的模型是否能够安全有效地提供一线管理(包括口服降糖药、降脂治疗和生活方式咨询)社区层面。
在随机分配到干预组的村庄中,在现有卫生部 (MoH) 乡村卫生工作者系统内运作的外行慢性病护理村卫生工作者 (CCVHW) 将有能力筛查和诊断 T2D,提供生活方式咨询,开处方和监测无并发症的 T2D 的一线抗糖尿病和降脂治疗,并为复杂的 T2D 提供治疗支持,由他们村庄中定制的临床决策支持应用程序(ComBaCaL 应用程序)提供支持。
对照组包括居住在村庄中的被诊断患有 T2D 的人,这些村庄也是 ComBaCaL 队列的一部分,但未对干预进行抽样(控制村庄),其中 CC-VHW 将仅筛查和诊断 T2D,随后进行标准化咨询并转诊至如果存在 T2D,但没有基于村庄的处方,则最近的医疗机构。 ComBaCaL 队列研究和嵌套 TwiCs 的总体目标是评估莱索托农村地区电子健康支持的、外行主导的慢性病控制措施的影响。
