Table 3 facilitates comparison between hospital discharge data and death certificate data for enumerating in-hospital deaths using the first-listed cause only (principal diagnosis for hospital discharge data, underlying cause for death certificates) and any diagnosis or cause of death listed in the respective records. Using a single diagnosis or cause of death only, the hospital data identified more deaths than the death certificates for all infections except infection with hepatitis A and NTM. Using the all-listed diagnosis or any causes of death, hospital data identified more deaths for all infections.
