NACHC and partners have identified various gaps and barriers preventing 
comprehensive extraction of nuanced data elements relating to the COVID-19 pandemic. NACHC will work with each partner individually in phase two of the project so that challenges can be addressed as additional and more detailed data are collected to allow a more in-depth analysis to begin. These data challenges include:

Inconsistent/variable use of COVID-19 diagnosis codes due to differences in coding regulation, guidance, workflows, and practice guidelines

Incomplete mapping of testing and vaccination data to formal codes 

Lack of consistent data capture for social determinants of health (SDOH)
