Intervention

The engagement commenced with a research study that documented overall employee COVID-19 seroprevalence and seroprevalence differences across job titles, geographic location, and demographic factors. The VSC team designed the research protocol and electronic screeners and surveys, obtained ethics approval from an independent Institutional Review Board, conducted electronic data collection, performed analyses, and prepared a scientific manuscript which is currently under peer review. The findings, which suggested among other things that one-third of seropositive participants had no previous Covid-19 symptoms or were unsure, are critical to shaping vaccination and health-messaging efforts targeted to healthcare workers.

Over the next few months--and prior to COVID-19 vaccine roll-out--VSC developed models to identify patient-level risk factors for COVID-19 test positivity, using our findings to 1) isolate gaps in care and target outreach and intervention, and 2) to enhance existing reporting processes by adding robust data-analytic capability. With the introduction of vaccines, VSC tracked roll-out and distribution, identifying correlates of uptake by patient demographic (ethnicity, housing, migrant-worker status) and organizational/programming (medical home, drug-treatment). VSC maintained regular communication with the client’s clinical and administrative leadership, periodically reporting findings along with questions to guide contextual considerations for the evidence.
