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
- Uiowa has an anomalously low proportion of patients with census tract information, which is expected due to known challenges at the institution
- There are many anomalous institutions related to ABPM data, demonstrating relative heterogeneity and differences in site practice when coding for or administering this procedure
- There are also several anomalous institutions related to antihypertensive exposure prior to cohort entry, which will require further investigation to determine why the population at these sites are exposed earlier than others.
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.
