Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | An Informational Packet Regarding Shingles and the HZV | An informational packet regarding shingles and the HZV was sent to patients identified by the EMR: 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. | 500 | 500 | OG000 |
