Several challenges impede effective healthcare financing: 1. Limited Resources: Many countries face budget constraints that limit their ability to allocate sufficient funds to health services. 2. Inequitable Distribution: Disparities in resource allocation can lead to inequities in healthcare access. 3. Corruption and Mismanagement: Mismanagement of funds can result in inefficient use of resources and reduced quality of care. 4. Economic Instability: Economic downturns can lead to reduced funding for health services, impacting public health initiatives.
