DCEO Healthcare: Info Envy: Dallas County’s Public Health Data Is Among the Best in the Country




One of Dallas’ top media outlets, D CEO Healthcare, ran a story on the reaction to PCCI, IHI and the Cincinnati Children’s Hospital Medical Center publishing an article in the New England Journal of Medicine on PCCI’s herd immunity program for Dallas County:

“Dallas County is home to some of the best COVID-19 data in the country. So when Steve Miff met with experts from Cincinnati Children’s Hospital Medical Center to publish his recent paper in the New England Journal of Medicine about herd immunity, he found that his out-of-town colleagues were jealous of the depth and breadth of information.”

PCCI Publishing: New England Journal of Medicine – Examining PCCI’s approach to determining COVID-19 herd immunity in Dallas County




The New England Journal of Medicine/Catalyst published an article authored by members of PCCI, the Institute for Healthcare Improvement and the  Cincinnati Children’s Hospital Medical Center that examines PCCI’s approach to determining COVID-19 herd immunity in Dallas County.

The article, “Rethinking Herd Immunity: Managing the Covid-19 Pandemic in a Dynamic Biological and Behavioral Environment,” was published under its “Innovations Care Delivery” section. The authors of the article share how a detailed understanding of local pandemic conditions is necessary to create focused, tailored responses. While achieving high levels of vaccination is important, exclusive focus on national vaccine targets de-emphasizes the complexities of Covid-19 population immunity. Herd immunity is dynamic and depends on the transmissibility of each new Covid-19 strain, the effectiveness of previous immunity due to previous infection and vaccination against these strains, and human behavior in local communities.

The authors developed a potential framework for enumerating and estimating community-wide immunity to Covid-19 with use of data reportable to local county public health authorities. Using data from Dallas County, Texas, they describe the interplay of vaccines and infection in terms of Covid-19 population immunity, the effect of variants on the ever-changing threshold for herd immunity, and how better access, algorithms, and use of real-time local immunity data could lead to more effective local population protection.
