一项了解老年人使用 ABRYSVO 疫苗预防严重呼吸道合胞病毒 (RSV) 感染的研究。
评估 ABRYSVO 疫苗对抗老年人严重下呼吸道感染有效性的回顾性研究
这项研究的主要目的是了解辉瑞 ABRYSVO 疫苗的有效性。 该疫苗有助于预防呼吸道合胞病毒 (RSV) 引起的感染。 RSV 是一种可引起呼吸道感染的病毒。 这些症状可能是类似感冒的症状,但在某些情况下可能会导致严重症状或住院治疗。
本研究仅使用从对医疗保健提供者的例行访问中收集的医疗保健数据。 这意味着参与者不会积极参加研究,也没有研究治疗方法。 该研究将研究大约两年的数据。 这项研究将查看来自以下来源的患者信息:
- 60岁及以上的成年人
- 有资格接受 ABRYSVO 疫苗接种

研究人群
这是一项使用现有医疗保健数据的回顾性数据库研究,不会主动招募患者。
TND:将包括符合以下条件的所有 KPSC 患者:1) 有资格根据 ACIP 接种 ABRYSVO 疫苗 2) 因 LRTI 诊断入院或在急诊室就诊,以及 3) 通过标准护理测试 (SOC) 或盲法进行 RSV 测试在研究期开始后使用多重 RT-PCR 呼吸小组检测在集中实验室中测试剩余 SOC 呼吸道标本(NP 拭子等),4)。 样本将被去识别化并进行测试,并与临床数据保持联系。
队列:队列研究将包括自研究期开始时有资格接种疫苗的所有 KPSC 成员(取决于 KPSC 疫苗接种开始日期和疫苗接种率)。
描述
纳入标准:
测试阴性设计:
- 根据当前 ACIP 建议,有资格接受 ABRYSVO 的 KPSC 患者,在研究期开始后因 ARI/LRTI(使用附件 2 表 1 中列出的国际疾病分类 (ICD) 代码定义)入院,并且已接受过RSV 测试,通过标准护理测试或对剩余呼吸道样本进行盲法研究测试。
- 对于根据 ED 入院评估 VE 的次要目标,TND 将包括有资格接受 ABRYSVO 的 KPSC 患者,这些患者在研究期开始后向 ED 提交 ARI/LRTI,并且通过标准护理测试或盲法进行了 RSV 测试研究测试剩余呼吸道样本。
- 我们将纳入索引日期(定义为住院或急诊入院日期(允许 45 天的管理间隙)之前 1 年的会员资格要求),以便于准确捕获合并症。
回顾性队列设计:
- 从学习期开始,所有 KPSC 成员都有资格获得 ABRYSVO。
- 对于队列研究,患者在研究期(索引日期)开始之前必须拥有至少 1 年的会员资格(允许 45 天的管理间隙),以便于准确捕获合并症。
排除标准:
符合以下任何标准的患者将不会被纳入研究:
测试阴性设计:
在住院或急诊就诊之前接受另一种许可或研究性 RSV 疫苗的患者将被排除在研究人群和分析之外。 如果索引日期在疫苗接种日期的特定时间范围内,患者将被排除在外,这将在下面的暴露部分中进一步概述。
队列设计:
在研究开始之前,患者将被排除在接受任何其他许可或研究性 RSV 疫苗的范围内;在研究期间接受任何其他许可或研究性 RSV 疫苗的患者将受到审查。
