Provenance
This data quality check was run on a database extracted from the The Preserving Kidney Function in Children With CKD (PRESERVE) Study. These results were not used for the study, but rather run on the study data after analysis was conducted as part of an SSQDA demonstration project.
Description
- Most patients (~94%) have at least one instance of an address geocoded to the census tract level, which aligns with expectations and indicates geocode related analyses will be feasible.
- Smaller portions of the cohort have evidence of other variables, like ABPM or kidney transplant, but these are expected to be rarer events within this patient pool so results align with expectations.
Response to Findings
Study team did not conduct further investigation or data intervention in response to these results because this was a demonstration project intended to highlight the functionality of the SQUBA tool.
