Abstract
The results of a Patient Event Sequencing check using the Single Site, Exploratory, Cross-Sectional parameters. This check investigates the distribution of time between an Hba1c result > 5.8% (index event) and an antidiabetic drug prescription (outcome event).

Provenance
This data quality check was run on a data extracted from the PAQS Query 3 Project. These results were not used for the query, but rather run on the query data after analysis was conducted as part of an SSQDA demonstration project.
Description
NOTE This is a single site analysis, but results for all sites are included in the output attached to this record for ease of review & reuse. General observations are recorded below, and details about specific institutions can be discovered in the raw output.
- These events occur together quite frequently, as expected, with only 15-20% of the cohort not having one of or both of the events.
- We would expect an associated lab result to indicate the need for treatment with an anti-diabetic agent, but there are a surprising number of instances where the antidiabetic agent occurs before the first recorded Hba1c > 5.8%. Part of this may be explained by clinicians using their judgment to prescribe medication even in more borderline cases, or it is possible that a related Hba1c level was recorded elsewhere before the patient was transferred to specialty care.
- Regardless of the order of events, the two events occur very close together, most often within a year of each other but they can also occur together often within 3 months.
Response to Findings
Study team did not conduct further investigation or data intervention in response to these results because this was a demonstration project.
