COVID-19-Associated Deaths by Date of Death - ARCHIVE

Note: DPH is updating and streamlining the COVID-19 cases, deaths, and testing data. As of 6/27/2022, the data will be published in four tables instead of twelve.

The COVID-19 Cases, Deaths, and Tests by Day dataset contains cases and test data by date of sample submission. The death data are by date of death. This dataset is updated daily and contains information back to the beginning of the pandemic. The data can be found at https://data.ct.gov/Health-and-Human-Services/COVID-19-Cases-Deaths-and-Tests-by-Day/g9vi-2ahj.

The COVID-19 State Metrics dataset contains over 93 columns of data. This dataset is updated daily and currently contains information starting June 21, 2022 to the present. The data can be found at https://data.ct.gov/Health-and-Human-Services/COVID-19-State-Level-Data/qmgw-5kp6 .

The COVID-19 County Metrics dataset contains 25 columns of data. This dataset is updated daily and currently contains information starting June 16, 2022 to the present. The data can be found at https://data.ct.gov/Health-and-Human-Services/COVID-19-County-Level-Data/ujiq-dy22 .

The COVID-19 Town Metrics dataset contains 16 columns of data. This dataset is updated daily and currently contains information starting June 16, 2022 to the present. The data can be found at https://data.ct.gov/Health-and-Human-Services/COVID-19-Town-Level-Data/icxw-cada . To protect confidentiality, if a town has fewer than 5 cases or positive NAAT tests over the past 7 days, those data will be suppressed.

Count of COVID-19-associated deaths by date of death. Deaths reported to either the OCME or DPH are included in the COVID-19 data. COVID-19-associated deaths include persons who tested positive for COVID-19 around the time of death and persons who were not tested for COVID-19 whose death certificate lists COVID-19 disease as a cause of death or a significant condition contributing to death.

Data on Connecticut deaths were obtained from the Connecticut Deaths Registry maintained by the DPH Office of Vital Records. Cause of death was determined by a death certifier (e.g., physician, APRN, medical examiner) using their best clinical judgment. Additionally, all COVID-19 deaths, including suspected or related, are required to be reported to OCME. On April 4, 2020, CT DPH and OCME released a joint memo to providers and facilities within Connecticut providing guidelines for certifying deaths due to COVID-19 that were consistent with the CDC’s guidelines and a reminder of the required reporting to OCME.25,26 As of July 1, 2021, OCME had reviewed every case reported and performed additional investigation on about one-third of reported deaths to better ascertain if COVID-19 did or did not cause or contribute to the death. Some of these investigations resulted in the OCME performing postmortem swabs for PCR testing on individuals whose deaths were suspected to be due to COVID-19, but antemortem diagnosis was unable to be made.31 The OCME issued or re-issued about 10% of COVID-19 death certificates and, when appropriate, removed COVID-19 from the death certificate. For standardization and tabulation of mortality statistics, written cause of death statements made by the certifiers on death certificates are sent to the National Center for Health Statistics (NCHS) at the CDC which assigns cause of death codes according to the International Causes of Disease 10th Revision (ICD-10) classification system.25,26 COVID-19 deaths in this report are defined as those for which the death certificate has an ICD-10 code of U07.1 as either a primary (underlying) or a contributing cause of death.

Note the counts in this dataset may vary from the death counts in the other COVID-19-related datasets published on data.ct.gov, where deaths are counted on the date reported rather than the date of death.

Starting in July 2020, this dataset will be updated every weekday. Data are subject to future revision as reporting changes.

注：DPH 正在对COVID-19的病例、死亡和检测数据进行更新和简化。自2022年6月27日起，数据将以四张表格的形式发布，而非之前的十二张。

COVID-19每日病例、死亡和检测数据集包含了样本提交日期的病例和检测数据。死亡数据按死亡日期记录。该数据集每日更新，并包含自疫情开始以来的所有信息。数据可从以下链接获取：https://data.ct.gov/Health-and-Human-Services/COVID-19-Cases-Deaths-and-Tests-by-Day/g9vi-2ahj。

COVID-19州级指标数据集包含超过93个数据列。该数据集每日更新，并自2022年6月21日起至当前日期为止包含信息。数据可从以下链接获取：https://data.ct.gov/Health-and-Human-Services/COVID-19-State-Level-Data/qmgw-5kp6。

COVID-19县级指标数据集包含25个数据列。该数据集每日更新，并自2022年6月16日起至当前日期为止包含信息。数据可从以下链接获取：https://data.ct.gov/Health-and-Human-Services/COVID-19-County-Level-Data/ujiq-dy22。

COVID-19镇级指标数据集包含16个数据列。该数据集每日更新，并自2022年6月16日起至当前日期为止包含信息。数据可从以下链接获取：https://data.ct.gov/Health-and-Human-Services/COVID-19-Town-Level-Data/icxw-cada。为了保护隐私，如果某个镇在过去7天内病例或阳性NAAT检测少于5例，则相关数据将被隐藏。

按死亡日期统计的COVID-19相关死亡人数。向OCME或DPH报告的死亡均包含在COVID-19数据中。COVID-19相关死亡包括在死亡时COVID-19检测结果呈阳性的人员，以及未接受COVID-19检测但其死亡证明书中列明COVID-19疾病为死亡原因或导致死亡的显著疾病。

康涅狄格州的死亡数据由DPH生命记录办公室维护的康涅狄格州死亡登记处获得。死亡原因由死亡证明人（例如，医生、APRN、法医病理学家）根据其最佳临床判断确定。此外，所有COVID-19死亡，包括疑似或相关死亡，均需向OCME报告。2020年4月4日，CT DPH和OCME联合发布了一份备忘录，向康涅狄格州内的提供者和机构提供关于认证COVID-19导致的死亡指南，这些指南与CDC的指南一致，并提醒必须向OCME报告。自2021年7月1日起，OCME审查了所有报告的案例，并对大约三分之一的报告死亡进行了额外调查，以更好地确定COVID-19是否导致或促成了死亡。其中一些调查导致OCME对疑似死于COVID-19但生前诊断无法确定的个人进行了尸检PCR检测。OCME发放或重新发放了大约10%的COVID-19死亡证明书，并在适当的情况下从死亡证明书中移除了COVID-19。为了标准化和编制死亡率统计，死亡证明书上证明人书写的死亡原因声明被发送至美国疾病控制与预防中心（CDC）的国家卫生统计中心（NCHS），该中心根据国际疾病分类第10次修订版（ICD-10）分类系统分配死亡原因代码。本报告中的COVID-19死亡被定义为死亡证明书中ICD-10代码为U07.1作为主要（基础）或死亡原因之一的情况。有关COVID-19死亡率的更多信息，请参阅以下链接：https://portal.ct.gov/DPH/Health-Information-Systems--Reporting/Mortality/Mortality-Statistics。

请注意，本数据集中的计数可能与data.ct.gov上发布的其他COVID-19相关数据集的死亡计数不同，后者按报告日期而非死亡日期计算死亡。

自2020年7月起，本数据集将在每个工作日更新。数据可能因报告变化而进行未来修订。
