Use of an Electronic Medical Record to Improve Standard Practice in the Primary Care Setting: A Randomized-Controlled Study of Herpes Zoster Vaccination Rates

Use of an Electronic Medical Record in the Primary Care Setting to Improve Herpes Zoster Vaccination Rates


Lead sponsor: Ohio State University

Brief Summary

Despite the significant benefits of herpes zoster vaccine (HZV), vaccination rates remain low. Electronic medical records (EMR) can serve as a practical strategy to better facilitate the application of preventative health care, such as increasing immunization rates. A new care model that can increase the herpes zoster vaccination rate, as well as other preventative health services, is warranted. The objective of this study is to investigate if the functions of an EMR, in combination with a pharmacist as part of the care team, can improve the herpes zoster vaccination rate.

Intervention type: Other

Intervention name: An informational packet regarding shingles and the HZV was sent to patients identified by the EMR

Description: The EMR generated a list of patients aged 60 or older without HZV documentation. Patients were categorized into two subgroups based on activated electronic patient portal (EPP) status. Randomized patients from each subgroup received an informational packet regarding shingles and the HZV by either the EMR or USPS mail, depending on EPP status. A pharmacist reviewed the medical chart of interested patients to assess if the HZV was clinically indicated; eligible patients were mailed a HZV prescription.
