Hello Fred,

We think that this might be a bug. What appears to be happening is that deleted outcome, intervention and comparison codetypes are still being found and listed in the 'Edit / create outcome' window. It is related to what happens when a code with child codes gets deleted.

We are looking at how to fix this but are unsure at this time if it will require a re-publish. In the meantime, what you could do is prefix your good 'outcome' codes with something that will help you identify them (ex. Utilisation could become 'O - Utilisation'). This way you can easily see which are the real ones.

I will let you know what we can do to fix this.

As for the difference between having multiple outcome codes and outcome classifications, outcome classifications could be useful in situations where you have multiple outcomes with the same outcome, intervention and comparison definitions. An example of their use might be sub-group analyses in which results are presented separately for males and females (but the same outcomes, interventions and comparison definations apply to both groups). You could have a male classification and a female classification.

Best regards,

Jeff
