摘要：The National Center for Health Statistics (NCHS) and the Influenza Division are collaborating to increase accuracy and decrease resources needed for pneumonia and influenza mortality surveillance in the United States Electronic death registration systems as well as funding to states have made reporting of mortality data to NCHS near real-time. We assessed the timeliness of the NCHS data and compared the data to the 122 Cities Reporting System (CMRS). Because of increased timeliness of the NCHS data and correlation to the 122 CMRS we will continue to monitor data from NCHS as a potential replacement for the 122 CMRS.
