For each child, the main cause of death must be identified. This is the most likely factor that lead to the death of the child. Sometimes it is not easy to decide which is the main cause and which are contributing causes. Any other contributing causes should also be recorded. If possible, an ICD 10 code should be allocated to the main as well as other contributing causes.
An example would be measles as the main cause with bacterial pneumonia and malnutrition as contributing causes.
It is important to have a formal document (death data capture sheet) on which all the relevant information as well as the causes and modifiable factors can be entered and coded.
