Abstract

Objective

Our objective is to assess the accuracy of the COVID-19 vaccination status within the Electronic Health Record for a panel of patients in a primary care practice when manual queries of the state immunization databases are required to access outside immunization records.

Results

A manual query of the local Immunization Information Systems for 4,114 adult patients with “unknown” vaccination status showed 44% of the patients were previously vaccinated. Attempts to assess the comprehensiveness of the Immunization Information Systems were hampered by incomplete documentation in the chart and poor response to patient outreach.

Conclusions 

When the interface between the patient chart and the local Immunization Information System depends on a manual query for the transfer of data, the COVID-19 vaccination status for a panel of patients is often inaccurate.

This study was reviewed by the University of Kansas Medical Center Institutional Review Board and was designated as a quality improvement project.
