Preventive and screening programs must be evaluated in terms of their coverage of high-risk versus low-risk individuals.

In order to evaluate and monitor the effectiveness of their service coverage, population-based preventive programs need the following:

- Accurate, updatable population registry using a (encrypted) personal health identification number for each enrollee

- Person-based information for each preventive service delivered

The data MCHP receives from such programs do not contain any personal identifiers (e.g. names, addresses, PHIN)

Generating such a profile may raise questions such as:

1. Why are mammography screening rates for women so low? How can these be raised?

2. Do regions with varying rates have different service delivery systems or are there other influencing factors?

3. How can programs address the needs for populations with low screening rates?
