Two sets of information are needed to analyse mortality data:

• Baseline population data. For calculating infant and under-5 mortality rates, the number if liveborn infants each year in that service or region is needed. For hospital mortality data, the total number of admission are needed. All deaths must be counted. This hospital data should be recorded in the ward admission books. Without this information, mortality rates cannot be calculated.
• The causes of death and modifiable factors. This information should be recorded on the forms completed at the mortality meetings.
