Covid-19 Vaccine Vaccine Hesitancy | Other: Covid-19 vaccine education materials | Not Applicable |
The investigator's preliminary work research at 15 ED sites across the US indicates that ED Usual Source of Care patients have particular health care access barriers, needs, and perceptions about vaccines (vaccine hesitancy) that require specific review beyond traditional (non-ED user) community engagement techniques. To gain insight about messaging that effectively addresses these barriers, needs, and perceptions, the investigators will conduct one on one interviews and focus group meetings with ED Usual Source of Care Patients and community partners.
At five safety net EDs (Zuckerberg San Francisco General, Thomas Jefferson University Hospital [Philadelphia], Methodist Hospital [Philadelphia], Harborview Medical Center [Seattle], and Duke University Medical Center [Durham, NC], the investigators will conduct a cluster-randomized, controlled trial of implementation of PROCOVAXED platforms, with COVID-19 and influenza vaccine acceptance rates on post-intervention ED surveys as the primary outcomes. Hypothesis: Implementation of PROCOVAXED platforms in EDs will be associated with increased acceptance of COVID-19 and influenza vaccines in ED patients.
One month after subjects' index ED visit enrollment in our PROCOVAXED implementation trial, the investigators will conduct electronic health record review and phone follow-up surveys to determine ED patient uptake (receipt) of COVID-19 and influenza vaccines. Hypothesis: Implementation of PROCOVAXED platforms in EDs will be associated with greater COVID-19 and influenza vaccine uptake in ED patients.
The investigators will conduct a cluster-randomized, controlled trial (RCT) of implementation of our PROCOVAXED platforms in 5 high-volume, safety net hospital EDs, testing two hypotheses that implementation of PROCOVAXED platforms will be associated with increased acceptance and uptake of COVID-19 and influenza vaccines in ED Usual Source of Care Patients.

Arm | Intervention/treatment |
---|---|
Experimental: Intervention Arm
Covid vaccine educational intervention consisting of vaccine messaging platforms (flyers, videos, scripted face-to-face messaging)

No Intervention: Non-interventional Arm
Usual care

- Covid-19 vaccine acceptance in the emergency department [ Time Frame: Within 6 hours of intervention ]
Participant acceptance of the COVID-19 vaccine assessed by the question "Would you accept the COVID-19 vaccine in the emergency department today if your doctor or provider asked you to get it?" The response choices for this question are "Yes", "No", and "No, but I might consider getting it at some other time".
This question will be asked once at the end of the Emergency Department visit.
- Covid-19 vaccine uptake [ Time Frame: Within 32 days of intervention ]
Participation uptake of the COVID-19 vaccine 32 days after enrollment assessed by confirmation of receipt of vaccine in one of 3 ways:
- Receipt in emergency department during index (enrollment) visit
- Electronic health record review 30 days after index visit
- Follow up phone call to participant at 28 to 32 days - We are asking patients if they received a COVID-19 vaccine since their index emergency department visit.
