Numerous Flaws Found in Flint Area Community Health and Environment Partnership Journal Articles

LANSING, MI – The Michigan Department of Health and Human Services (MDHHS) recently learned that Wayne State University, the University of Michigan and Colorado State University will publish two journal articles based on data from the Flint Area Community Health and Environment Partnership (FACHEP) project.

Previously, FACHEP provided MDHHS with a draft of these journal articles which claim to explore the statistical relationship between the change in water source and the incidence of Legionnaire’s Disease in Flint and other Southeast Michigan counties and the prevalence of various strains of legionella found in the cities of Flint and Detroit.

MDHHS reviewed the draft articles as did an external, independent third party, KWR Watercycle Research Institute (KWR).  KWR was asked to review the FACHEP project on behalf of the Michigan Department of Management and Budget.  Both MDHHS and KWR found numerous flaws in the articles which were brought to FACHEP’s attention and appear to remain unaddressed.  By publishing these inaccurate, incomplete studies at this point, FACHEP has done nothing to help the citizens of Flint and has only added to the public confusion on this issue.

The researchers not only failed to accurately describe conversations with MDHHS, but utilized variables in their dataset that inaccurately reflect the timing associated with cases of Legionnaires in Flint. Researchers also overestimate the risk to public health by focusing on a strain of the bacteria, serogroup 6, that is not typically associated with Legionnaires’ disease.  FACHEP acknowledges that 16/18 of the environmental isolates that it found were serotype 6.  Not a single case of serogroup 6 Legionnaire’s Disease was identified in Genesee county, despite widespread use of legionella cultures.   As even FACHEP recognizes, more research is needed to evaluate the risk of this strain.  Publishing this report now, however, implies that a public health risk exists when there may not be one.

In addition KWR noted that the report focusing on the link between the switch in the Flint water and increase in Legionnaires’ disease “…raises a number of serious critical questions with regard to the applied methodology, and gives little insight in the actual crude numbers in the various analyses.”  KWR added that “[t]he paper is difficult to follow in places and does not provide insight into the crude data with which the statistical analyses were performed. The authors claim that their analyses reveal causal relations, but failed to distinguish between the demonstration of a statistical association, and its interpretation as a causal relation.”

Based upon concerns over FACHEP’s methodology, the State of Michigan informed FACHEP that it was only willing to continue the partnership under the independent review and oversight of KWR.  FACHEP rejected the State’s offer to continue under these conditions.
