NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Development of A User-Driven, Web-Based Dashboard Leveraging COVID-19 Mathematical Models for Rapid Decision Support – A Case Study in Malawi
ABSTRACT
Mathematical modeling of COVID-19 transmission has been instrumental in the global pandemic, particularly to governments in many low- and middle-income countries (LMICs), where empirical data and active surveillance is limited. Simulations can be used to understand disease trajectory and impacts of policy options at little additional cost. We describe an automated, open-source, and web-based dashboard designed to empower Malawi government officials to understand the ramifications of certain policy interventions from a mathematical model of COVID-19 transmission. The dynamic dashboard allows policymakers to simulate scenarios of various COVID responses by allowing them to manipulate model inputs like percentage of population using cloth masks, percentage of population abiding by physical distancing recommendations, and the length of both these interventions in days. The dashboard’s outputs include COVID-19 cases, hospitalizations, intensive care unit (ICU) stays, and deaths based on the user-defined parameters and level of interest for the data (i.e., administrative levels like traditional authority-, district-, or national-level). It also compares the outputs from the user-defined simulation with a baseline scenario that conservatively estimates 15% of the population masking and 8% abiding by physical distancing guidelines. Our dynamic dashboard not only generates pertinent outputs to formulating a pandemic policy response, but it also offers an intuitive, streamlined, and real-time user experience to policymakers who may lack backgrounds in epidemiology and programming. LMICs should continue to invest in their country’s data collection, digital infrastructures, and technical training for key stakeholders to support widespread use of these evidence-based, decision-support tools in the future.
