Evaluating the service readiness of a Paraguay public healthcare center for the primary healthcare system using the WHO SARA tool

This study demonstrates that merely implementing health system-related policies, such as national health plans or service coverage mandates, is insufficient without targeted strategies addressing health workforce distribution, resource allocation, and health infrastructure development. The term 'inequality gaps' refers specifically to disparities in healthcare access, particularly in the distribution of healthcare workers and essential medical resources. This study provides novel quantitative evidence on how integrated interventions -combining infrastructure development, workforce capacity building and resource optimization - can significantly enhance PHC service readiness in upper middle-income countries like Paraguay. These findings offer valuable insights for policymakers aiming to improve healthcare accessibility and service delivery.
