Impact assessment method

This method measures the cognitive impact of knowledge resources on health professionals

It comprises a 7 item scale developed from an extensive literature review. 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 

The tool has been used by the team to test information gained via: 

  • hand held devices,  
  • evidence summaries  
  • alerts by email and  
  • more recently on information for patients. 

The impact assessment method was developed by a Canadian team from McGill University (Roland Grad and Pierre Pluye)
