Information on every case of self-harm should be either recorded on a paper data registration form or entered directly into an electronic database.
Where possible, data items should be organized in drop-down menus to increase efficiency.
- For the data item specifying the method of intentional self-harm, the ICD-10 codes should be listed (X60−X84), with an “other” category allowing for specification of other methods.
When necessary, an option must be given for selection of multiple answers, for example method of self-harm.
An example of a paper data registration form and a screenshot of an electronic data entry system can be found in the Supplementary Materials section.
