Why is it important?

Evaluating the success of a QI intervention:

• Measures impact and effectiveness
• Identifies strengths and weaknesses
• Ensures sustainability
• Demonstrates value to stakeholders
• Guides future QI work.

How to evaluate a QI project

The NHS Institute for Innovation and Improvement (2005, pp. 13-15) identifies 5 key areas which should be considered when designing an evaluation plan:

1. Summative or formative evaluation -- i.e. Were objectives met or why these results occurred.
2. Outcome or process evaluations -- i.e. impact or internal operations.
3. Quantitative or qualitative data
4. Unitary approach or pluralistic approach -- i.e. single or multiple perspectives.
5. Experimental approach or naturalistic approach -- i.e. using controls vs. naturally occurring activities
