结核病 (TB) 诊断的延迟和治疗后续的损失显著增加了巴西的健康损失. 优先考虑更快的诊断和更好的患者随访对于减少结核病疾病负担至关重要.
科学领域:
- 公共卫生 公共卫生
- 流行病学 流行病学
- 卫生经济学 卫生经济学
背景情况:
- 巴西的结核病 (TB) 护理面临诸多挑战,包括诊断延迟,治疗无效以及患者失去随访.
- 这些差距导致严重的健康损失和结核病计划成本.
研究的目的:
- 估计与巴西结核病护理级联的每个阶段相关的健康损失和结核病计划成本.
- 确定结核病护理级联中的关键缺口,这些缺口有助于整体疾病负担.
主要方法:
- 开发了一个马尔科夫模型来模拟巴西的结核病护理级联和终身健康结果.
- 模型按年龄,艾滋病毒状况,耐药性,地区和疾病严重程度分层,使用来自国家卫生信息系统 (SINAN,SIM) 的数据.
- 模拟了假设场景,以量化与消除特定护理级联差距相关的健康损失和成本.
主要成果:
- 延迟诊断是导致结核病导致的残疾调整寿命年 (DALYs) 的最大贡献者,其次是结核病后的后果和对随访的损失.
- 消除延迟诊断可能会使结核病DALY减少71%,结核病后连续症减少41%,随访损失减少10%.
- 护理级联改进对卫生系统总成本的影响很小,尽管结核病诊断和假阳性病例的治疗占计划成本的10.2%.
结论:
- 诊断的延迟,疾病后的后续和治疗后的随访损失是巴西结核病负担的主要驱动因素.
- 优先考虑减少诊断延迟,改善结核病后护理,并尽量减少对随访的治疗损失,对于减轻结核病疾病负担至关重要.
