For months, we have been collecting COVID-19 data, scrutinizing publicly available data definitions, and engaging in frequent conversations with jurisdictions to understand the data they share.

During this process, we have focused on three aspects of COVID-19 data reporting: 1) how the state defines and reports key metrics, such as testing data, cases, hospitalizations, and deaths, 2) how the state presents information about COVID-19 in long-term-care facilities, and 3) how the state reports race and ethnicity data.

Our assessment below reflects both the thoroughness of Connecticut’s reporting and the completeness and clarity of their data descriptions. We hope this work will not only help our data users to better grasp the limitations of these numbers but also might help health officials to understand the differences in data reporting across jurisdictions.

We require data definitions to be accessible from a state’s data pages and presented in a location where it is clear they will be maintained. Examples include data definition documents, data FAQs, dashboard footnotes, or definitions appearing daily in press releases.

State-level metrics

Some issues exist:

  • does not regularly provide total tests in terms of unique people tested
  • does not provide numbers for patients currently on ventilators with COVID-19
  • does not provide numbers for patients currently in the ICU with COVID-19
  • does not regularly provide a cumulative number of patients hospitalized with COVID-19

Race and Ethnicity

Some issues exist:

  • does not report race / ethnicity data for tests and hospitalizations
  • reports Asian or Pacific Islander, a category that has not been used for federal data since 1997, making comparisons more difficult
  • reports race data for 64% of cases and 98% of deaths

Long-Term Care

Few issues exist:

  • Connecticut’s system for reporting resident deaths changed on July 15, 2020 from the Office of the Chief Medical Examiner to Long-Term Care Mutual Aid Plan. Each system has differing definitions of a COVID-19 associated deaths. As a result, there is a possibility of duplication of death counts. Interpret this data with caution.
  • does not provide information about facilities with open and closed outbreaks, or date of last case
