Virtual First Quarter meeting: COVID 19 Data Quality Case Study

Houston DAMA Busines and Presentation
Presentation Title: “Covid-19 Data Quality Case Study”
Author/Speaker: Michael Scofield, M.B.A.
Asst. Professor Loma Linda University

Description:
Managing a public health crisis requires reliable metrics, generally on an aggregate level. Unlike many industrial processes, raw data about a pandemic is captured through a variety of distributed locations, events, and jurisdiction. Data quality challenges abound. Definitions of events, metrics, and timing of aggregates create ambiguities and uncertainties.

We will examine critical elements of the current pandemic including explaining how a virus works, definitions of antigens, antibodies, co-morbidity, false negatives, and long-haul symptoms resulting from Covid-19 infection. We introduce a graphic model of the chain of events in a patient’s illness, and how we could benefit from more metrics with greater precision. We will introduce the concept of the event-to-information supply chain and issues of timing and ambiguity of high-level metrics. We show examples of political bias in expression and manipulation of information. We will finally look at the quality challenges of vaccine testing and distribution.
