Transcript of ALE Presentation: A Multiple Cause Analysis of Massachusetts Trends in HIV and HCV Mortality
A Multiple Cause Analysis of Infectious Disease Mortality in Massachusetts,2002-2011DAVID MEYERS
Background Infectious disease mortality accounts totally for 3% of all deaths in the state looking at underlying cause
There may be a recent resurgence of conditions such as sepsis, HIV and Hepatitis C
Long term trends in deaths data are not commonly examined in Massachusetts
Underlying Cause of Death alone may not account for the full extent of infectious disease related mortality
Driving Questions What is the extent of mortality related to infectious disease in Massachusetts over the past decade?
How is infectious disease related mortality in Massachusetts distributed across age, gender, and race?
How is infectious disease related mortality in Massachusetts distributed in space and time?
Methods 4 Infectious Diseases were identified based on prevalence and public health importance to be the focus of analysis
◦ Sepsis, Influenza/Pneumonia, Hepatitis C (HCV), HIV/AIDS
All deaths with any Infectious disease ICD code were pulled from the Massachusetts Death Certificate Database from 2002-2011
Shapefiles for Massachusetts Census Tracts were taken from MassGIS
Analysis and data management took place in SAS, ArcGIS, Joinpoint, and SatScan
Methods (continued) Age-Adjusted Standardized Mortality Rates were calculated by race, age, and gender for each ID of interest
Trends in mortality over time were calculated in the Joinpoint Regression Program
Spatial clusters of mortality were examined using a 5-step geo-processing approach
Spatial-Temporal Clusters were examined using a Discrete Poisson space-time model in SatScan
Results
Results 91,208 deaths were associated with infectious disease causes over the ten-year period
2,913 deaths were associated with Hepatitis C
1,905 deaths were associated with HIV
33,858 deaths were associated with Sepsis
55,718 deaths were associated with Influenza/Pneumonia
ICD total Code Category
A04 2428 Other bacterial intestinal infections (E.Coli, campylobacter enteritis, Yersinia enterocolitica, clostridium difficile, etc…)
A49 1587 Bacterial infection of unspecified site (Staph, Strep, Haemophilus influenza, mycoplasma, other)

Spatial Clusters
Discussion and Conclusions
Discussion Clear disparities exist across race and age groups in each investigated disease
There are clear locations around the state that merit further investigation
◦ South Boston, Worcester, Springfield, New Bedford, Dracut
Significant space-time clustering has occurred
Limitations Death certificates are not always accurate, especially in regards to race and contributing cause of death
Spatial and space-time clusters are difficult to distinguish from noise
It is difficult to select scanning windows in SaTScan
The infectious disease may have been a chronic condition and less of a cause of death
Conclusions Multiple Cause Data is an underutilized resource
There exist clear populations and locations that should be the center of public health focus
Spatial Cluster, and Space-time cluster analyses are valuable resources for mortality data analysis
