The Impact Assessment Method was developed by a Canadian team from McGill University (Roland Grad and Pierre Pluye) to measure the cognitive impact of knowledge resources on health professionals.

It comprises a 7 item scale developed from an extensive literature review.  It has been well validated and tested.

The scale includes:

• No impact
• Reassurance (I was more confident)
• Confirmation (I was doing the right thing)
• Practice improvement (clinical decision making was enhanced)
• Recall (I recalled something I’d forgotten)
• Learning (I learned something new or updated my knowledge)
• Other

It has been used to test information gained via hand held devices, evidence summaries and alerts by email and more recently on information for patients.
