COVID Drug Effect Drug Interaction Adverse Drug Event |
Certain investigational agents have been described in observational series or are being used anecdotally based on in vitro or extrapolated evidence. It is important to acknowledge that there are no controlled data supporting the use of any of these agents, and their efficacy for COVID-19 is unknown. FDA-approved drugs such as chloroquine/hydroxychloroquine, lopinavir/ritonavir, monoclonal IL-6 antibodies, JAK inhibitors, thalidomide, and the new investigational drug remdesivir, have been proposed for repurposing to fight COVID-19 and its complications.
A medication risk stratification strategy will be used to simulate the impacts of different potential repurposed drugs for COVID-19 and the Medication Risk Score (MRS) which is used as a predictive tool for ADEs. A retrospective study will be conducted using de-identified drug claims data for commercially insured patients.

- Calculate the Medication Risk Score of de-identified participants from Medicare/Medicaid and commercial health insurance plans using their current drug regimen via our proprietary risk stratification process. [ Time Frame: Three months ]Quantitative
- Simulate the Medication Risk Score following the addition of different repurposed drugs against COVID-19 to their current drug regimen via our proprietary risk stratification process. [ Time Frame: Three months ]Quantitative
- Compare the impact (change) on the Medication Risk Score using the calculate before score and simulated after score following the addition of repurposed drugs for COVID-19 to the drug regimens of patients enrolled in the study. [ Time Frame: Three months ]Quantitative
- Measure the effects of various repurposed drugs for COVID-19 on each of the five factors computed by algorithms to derive the Medication Risk Score will be calculated via our proprietary risk stratification process. [ Time Frame: Three months ]Quantitative
- Comparison of the Medication Risk Score and the effects of the addition of repurposed drugs on the drug regimen between participants with Medicare/Medicaid vs. commercial health insurance plans will be assessed. [ Time Frame: Six months ]Qualitative
- Measure the effects on Medication Risk Score of various repurposed drugs for COVID-19 within subgroups of patients classified by specific diseases or drugs used and the impact of various covariables. [ Time Frame: One year ]Qualitative
