Summary

This study is a pharmacoepidemiologic method study based on the secondary use of pre-existing data that examines whether TriNetX, a global health research network encompassing a worldwide electronic health record (EHR), database in the US is an appropriate real-world data (RWD) source for conducting chlamydia-related research to support the chlamydia trachomatis (CT) messenger Ribonucleic acid (mRNA) vaccine program.

There are two primary objectives for this study:

  1. To determine the validity of ICD, Tenth Revision, Clinical Modification (ICD-10-CM) diagnostic codes to identify patients with chlamydial infections using TriNetX EHR data in the US
  2. To describe screening or diagnostic testing and treatment patterns in patients with chlamydia using TriNetX EHR data in the US

There are also two secondary objectives for this study:

  1. To explore the feasibility of developing a modified algorithm for identifying patients with chlamydia applicable for Merative MarketScan Commercial Claims and Encounters (CCAE) database based on the findings from the primary objectives
  2. To compare patient characteristics, use of screening or diagnostic testing, and treatment patterns among patients with chlamydia between TriNetX EHR data and the MarketScan CCAE data in the US

The index date is the date of the first-recorded diagnosis code, or the date of the first-recorded NAAT result when no diagnosis code for chlamydia exists
Patients with at least one visit within 30 days both before and after their index date

Exclusion Criteria

Patients with no documented ICD-10-CM diagnosis for chlamydia who possessed unknown laboratory test results for chlamydia during the study period (removed from ICD validation assessment in primary analysis)
Patients with an ICD-10-CM diagnosis without a corresponding laboratory test (removed from ICD validation assessment in primary analysis)
