Area of Science:

  • Epidemiology
  • Public Health
  • Biostatistics

Background:

  • Hepatitis C virus (HCV) infection is a significant public health concern.
  • Accurate mortality data is crucial for understanding the burden of HCV.
  • Previous estimates of HCV mortality using single data sources were found to be underestimates.

Purpose of the Study:

  • To estimate the mortality rate of hepatitis C in New York State (excluding New York City) in 1997.
  • To evaluate the effectiveness of the capture-recapture method for estimating HCV mortality.

Main Methods:

  • Utilized the New York State hospital discharge database.
  • Incorporated the multiple cause-of-death file.
  • Applied the capture-recapture method to combine data from both sources.

Main Results:

  • Individual data sources significantly underestimated hepatitis C mortality.
  • The capture-recapture method provided a more accurate estimation.
  • This method proved efficient for assessing hepatitis C-related deaths.

Conclusions:

  • Combining hospital discharge data and death records is essential for accurate hepatitis C mortality estimation.
  • The capture-recapture method is an efficient approach for this purpose.
  • Improved data linkage strategies are vital for public health surveillance of infectious diseases.
