An example of a clinical care process measure is:

Clinical care process measures evaluate specific actions taken during patient care to ensure adherence to best practices and guidelines. These measures focus on whether healthcare providers perform particular interventions that are known to improve patient outcomes.

Option B, "Administration of beta blocker," is a direct example of a clinical care process measure. For instance, administering a beta blocker to patients after a myocardial infarction is a recommended practice to reduce mortality and prevent further cardiac events. Monitoring the rate at which eligible patients receive beta blockers assesses compliance with this evidence-based guideline.

The other options represent different types of measures:

Patient experience (Option A): This is an outcome measure that captures patients' perceptions of their care, such as satisfaction and communication effectiveness.

Case mix mortality (Option C): This is an outcome measure that reflects the mortality rate within a specific patient population, adjusted for the diversity and severity of casestreated.

30-day readmission rate (Option D): This is an outcome measure indicating the percentage of patients who are readmitted to a hospital within 30 days of discharge, often used to assess the quality of care transitions and discharge planning.

Therefore, among the options provided, "Administration of beta blocker" is the example of a clinical care process measure.
