What levels can health care system performance be measured at?

Measuring health care system performance can be effectively conducted at both the micro and macro levels, which is why this option is the correct choice.

At the micro level, performance can be assessed by evaluating specific clinical practices, individual health care providers, or smaller health care facilities. This level of measurement focuses on aspects such as patient outcomes, quality of care provided, efficiency of services, and provider-patient interactions. These evaluations help identify areas for improvement within specific health care settings.

On the other hand, the macro level involves a broader perspective, considering the performance of entire health care systems or populations. Metrics at this level might include overall population health outcomes, healthcare accessibility, equity in health services, and performance of the health system as a whole. This level of assessment helps policymakers understand how well the system is serving the public and where changes might be necessary for improving health care delivery on a large scale.

In summary, both levels provide valuable insights, enabling comprehensive assessments of health care system performance, guiding efforts for improvement and reform.
