Could you clarify whether you are testing the clinician's knowledge when training to use a scale, or whether you are looking for a scale to help clinicians to assess the medical stage/state of their treatment. Regarding the latter - The Clinical Opiate Withdrawal Scale is a good reference to start with: http://www.tandfonline.com/doi/abs/10.1080/02791072.2003.10400007
Thanks for your response and am sorry for the ambiguity. I am testing the clinican's knowledge before and after training on the use of the clinical opiate withdrawal scale (COWS) tool.
