摘要

背景:严重急性呼吸道感染(SARI)是全球死亡的主要原因之一,在 COVID-19 大流行期间达到高峰。我们分析了孟加拉国大流行前期与 SARI 相关的死亡病例,以确定导致死亡的因素:我们分析了孟加拉国九家三级医院的医院流感监测数据。我们将 2018 年 3 月至 2020 年 2 月视为大流行前期,2020 年 3 月至 2022 年 2 月视为大流行期,并将成年(≥ 18 岁)参与者纳入研究范围。监测医生确定了符合 WHO-SARI 病例定义的住院患者,并收集了出院时和出院后 30 天的人口统计学、临床特征和结果。我们对采集的鼻咽和口咽拭子进行了流感和 SARS-CoV-2 病毒的 rRT-PCR 检测。我们使用多变量考克斯回归模型计算了这些成人患者中与 SARI 死亡相关因素的危险比 (HR):我们共收治了大流行前的 4392 名 SARI 患者和大流行期间的 3824 名 SARI 患者。与大流行前的 6.01% (264) [院内:2.01% (89);出院后:4% (175)]相比,大流行期间的病死率更高:13.62% (521) [院内:6.45% (247);出院后:7.17% (274)](P 结论:在大流行期间,SARI 患者的病死率比大流行前更高:大流行期间,SARI 死亡率上升;流感相关死亡率下降,SARS-CoV-2 导致的 SARI 死亡占三分之一以上。在这两个时期,出院后死亡率均高于院内死亡率。限制过早出院、加强出院后监测和护理服务可以减少意外死亡。为更好地了解出院后死亡率而开展的形成性研究对于减少 SARI 死亡至关重要。

Characterizing deaths among adult patients with severe acute respiratory infection: during the pre- and COVID-19 pandemic periods in Bangladesh, 2018-2022.

Background: Severe acute respiratory infection (SARI) is a leading cause of mortality globally, peaking during the COVID-19 pandemic. We analyzed SARI-associated deaths during the pre-and-pandemic periods in Bangladesh to identify the contributing factors.

Methods: We analyzed data from hospital-based influenza surveillance at nine tertiary-level hospitals in Bangladesh. We considered March 2018-February 2020 as the pre-pandemic period and March 2020-February 2022 as the pandemic period and included adult (≥ 18 years) participants in our study. Surveillance physicians identified WHO-SARI case definition meeting inpatients and collected demographics, clinical characteristics, and outcomes at hospital discharge and 30 days post-discharge. We performed rRT-PCR for influenza and SARS-CoV-2 viruses on collected nasopharyngeal and oropharyngeal swabs. We used multivariable Cox's regression models to calculate the hazard ratio (HR) for factors associated with SARI deaths in these adult patients.

Results: We enrolled 4392 SARI patients during the pre-pandemic and 3824 SARI patients during the pandemic period. Case fatality ratio was higher during the pandemic: 13.62% (521) [in-hospital: 6.45% (247); post-discharge: 7.17% (274)] compared to pre-pandemic, 6.01% (264) [in-hospital: 2.01% (89), post-discharge: 4% (175)] (p < 0.001). Pre-pandemic, influenza was detected in 14% (37/264) of SARI deaths. Influenza was detected during the pandemic in 2.3% (12/521), SARS-CoV-2 in 41.8% (218/521), and both viruses in only one SARI death. History of smoking and the presence of 1 or more co-morbid conditions independently attributed to SARI deaths in adults in the pre-pandemic period. SARI deaths in such patients were also associated with respiratory difficulties on admission in both pre-pandemic (aHR 2.36; 95% CI:1.65-3.36) and pandemic period (aHR 2.30; 95% CI: 1.57-3.35) after accounting for age, sex, smoking status, presence of 1 or more co-morbid conditions, and detection of influenza and SARS-CoV-2 viruses.

Conclusions: During the pandemic, SARI mortality increased; influenza-associated mortality declined, and SARS-CoV-2 caused over a third of SARI deaths. Post-discharge mortality was higher than in-hospital mortality during both periods. Limiting premature discharge and strengthening post-discharge monitoring and nursing services could reduce unexpected deaths. Formative research to better understand post-discharge mortality is essential to reduce SARI deaths.
