Elements of the Prevention Index

1. Includes all recommended services plus nonrecommended services with significant resource implications.

2. Regularly modified according to current recommendations.

3. Requires a recommended service interval to be defined for appropriate subgroups.

4. Based on person-time; assesses proportion of time during a service interval that is covered by the service, or which has duplicated coverage.

5. Weighted by prevention priorities.

6. Weighted by proportion of persons rarely served where associated with higher risk.

7. Can be weighted by the proportion of resources expended on excess services.

8. Analyzable at the plan, clinic, provider, and patient level.

9. Obtainable entirely from electronic record (except for patient satisfaction).

10. Produces equally weighted subscales, averaged in the overall score: (a) Adult Clinical Services;(b) Adult Interactive Services; (c) Childhood Immunization; (d) Never/Rarely-Served

11. Can be used to evaluate excess service delivery as quality of care issue.
