A 2022 WHO policy brief, titled Benefit Design: The Perspective from Health Financing Policy, dives deeper into the issue of linking benefit package design to health financing mechanisms (principle #6 of the HBP Principles report), emphasizing the importance of reducing uncertainty about both entitlements and conditions of access in the benefit design process. The recommendation to apply simple co-payments as a measure of financial protection is emphasized. A key takeaway is that aligning benefit design with robust health financing mechanisms and service delivery objectives is essential for effective implementation.
