Step 1: Recall the theme of the World Health Report 2008, titled "Primary Health Care: Now More Than Ever," which called for a renewal of primary health care through a set of reforms.
Step 2: List the four reforms proposed in the report. They are universal coverage reforms (often described in the social or equity sense), service delivery reforms, leadership reforms, and public policy reforms.
Step 3: Match the options to these reforms. Social reforms (universal coverage and equity), leadership reforms, and policy (public policy) reforms all correspond to the proposed reforms.
Step 4: Economic reforms are not one of the four reforms named in the World Health Report 2008. This is the exception.
Conclusion: The reform not proposed in the World Health Report 2008 is economic reforms, so the correct answer is option 4.
