出于非COVID-19原因访问急诊室 (ED) 的退伍军人由于实施的安全措施而没有面临增加的感染风险. 这些降低风险的程序有效地减少了COVID-19在ED患者中的传播.
科学领域:
- 公共卫生 公共卫生
- 传染病流行病学 传染病流行病学
- 医疗保健管理的管理
背景情况:
- 由于COVID-19的流行,急诊室 (ED) 的访问量减少.
- 风险减轻程序对退伍军人的急救设置中COVID-19传播的影响尚不清楚.
- 需要进行一项研究,以评估在ED寻求非COVID-19护理的退伍军人中COVID-19阳性率.
研究的目的:
- 评估退伍军人事务大洛杉矶医疗保健系统 (VAGLAHS) 风险减轻策略的有效性.
- 为了确定是否参观ED的退伍军人COVID-19以外的条件有更高的感染病毒的风险.
- 为了评估非COVID-19诊断的ED访问后21天内COVID-19阳性率.
主要方法:
- 回顾患者访问VAGLAHS ED的病例,以诊断与COVID-19无关的疾病.
- 对这些患者在首次ED访问后21天内COVID-19阳性率的分析.
- 在ED中的阳性率与更广泛的VAGLAHS中的率的比较.
主要成果:
- VAGLAHS ED实施了全面的风险减轻程序,包括户外测试,隔离协议,加强消毒,个人防护设备培训,专门的呼吸道团队,数字通信和社交距离.
- 在非COVID-19相关问题访问VAGLAHS ED的患者中,COVID-19阳性率很低 (0%至6.7%).
- 这一比率与在更广泛的VAGLAHS (6.9%至33.3%) 中观察到的阳性率相似或低于这一比率.
结论:
- 风险减轻程序成功地将寻求非COVID-19护理的退伍军人在VAGLAHS ED.中成功减少了COVID-19暴露和随后的诊断.
- 在VAGLAHS ED寻求紧急医疗护理并没有增加退伍军人在疫情期间感染COVID-19的风险.
- 该研究表明,在公共卫生危机期间,医疗保健机构中针对性安全协议的有效性.
