3 What s constitutes a great indicator? I 1. Importance of the Measure Relevance for stakeholders Health importance Potential for improvement Susceptibility of being influenced Prof. Dr. Michael Simon 3

4 What s constitutes a great indicator? II 2. Scientific Soundness Explicitness of evidence Strength of evidence Reliability Validity Allowance for stratification or case-mix adjustment if appropriate. Comprehensible Prof. Dr. Michael Simon 4

5 What s constitutes a great indicator? III 3. Feasibility Explicit specification Data availability Prof. Dr. Michael Simon 5

7 Nursing Sensitivity Nursing-sensitive performance measures are processes and outcomes and structural proxies for these processes and outcomes (e.g., skill mix, nurse staffing hours) that are affected, provided, and/or influenced by nursing personnel, but for which nursing is not exclusively responsible. Nursingsensitive measures must be quantifiably influenced by nursing personnel, but the relationship is not necessarily causal. National Quality Forum.
