Trusted Messenger Intervention

A nested waitlist design in which patients and staff are nested within two inpatient psychiatric units. New Hampshire Hospital staff will be trained to deliver the trusted messenger intervention up to 24 patients on the first unit while the second unit receives care as usual, during which time in-house vaccinations among patients on both units will be tracked in a registry. After a 3-week study period, up to 24 patients on the second unit will receive the trusted messenger intervention and followed for a period of 3 weeks. The trusted messenger intervention will consist of staff who are trained to engage patients informally and assist building social norms for vaccine uptake supported by weekly and as-needed check-ins with a content expert who can answer specific vaccine related questions over a 3 week period.
