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 a T2DM diagnosis (index event) and a CKD diagnosis (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.

  • Generally, about 60-70% of the cohort does not have both events, and because a T2DM diagnosis was a requirement of cohort entry, this really means that a CKD diagnosis is not present for those cohort members. The exception to this is the pediatric cohort, for whom CKD is much less prevalent. For those institutions, 95%+ of the cohort does not have a CKD diagnosis.
  • For patients who do have both diagnoses, the CKD diagnosis generally occurs after the T2DM diagnosis. It is rare for CKD to precede T2DM.
  • The two events occurring within a year of each other is the most common of the pre-set thresholds, but the distributions demonstrate that it is likely more common for these diagnoses to occur farther apart, probably on the order of a few years.

Response to Findings

Study team did not conduct further investigation or data intervention in response to these results because this was a demonstration project.

The Patient Event Sequencing module computes the days between two user-specified events and summarizes the distribution within the cohort. It assesses the plausibility of the sequence of two user-provided clinical events as they appear in a patient's record. This allows the user to ensure that the two events, like a cancer diagnosis and chemotherapy, occur in a sensible order and within an expected length of time.
