As per my knowledge, an Edit Check is a single Rule or "Constraint" for a particular Data field. It may be a rule written to restrict the dirty data into the database as per the protocol of that particular study.
a) The "Date of Visit" should not be lesser than the Informed Consent Date.
b) The Start Date of the Adverse event should not be after the End Date of the Adverse Event.
these two are two saperate Edit checks written for two different requirements.
Like this, For any particulae Study, We have to write Several Edit Checks which will be in a particular format, which will have a template.
Any Edit Check Spec will have different variables like SL_No, Edit Check Reference NUmber, Type of Edit Check, Discription, Edit Check Rule, etc...
These Variables are very induvidual and its left to the company to customize as per the clients and most adoptable way on which these Edit Checks will be implemented. These are also called as Data VAlidation Specifications some times.
To Conclude, Edit Check is 1 Rule, and Edit Check Specification is nothing but a Document which consists f Many Many Rules as a whole. Thats all... I have tried to put as simple as possible, Please revert If Something is not clear.... Any other people can try breaking down these matter to more simplistic way if possible.....
