Supplementary values - paediatric data collection

For some ePPOC data items, negative values are assigned to denote different types of non-response or missingness. These values are defined in the table below.

Value	Description

Value	Description
-2	The patient, parent/carer or pain management service did not enter a response for this item
-4	A response to this item was not required (i.e. the item was not applicable to that patient or parent/carer)
-5	This value is used for a range of specific situations where data are missing for reasons other than -2 or -4 above. For example, a questionnaire was created in epiCentre but the patient has not accessed the questionnaire link to respond, or a questionnaire has been created but not sent.
