After implementing an electronic medical records (EMR) system in a department, the next step is to assess its effectiveness to ensure it meets goals before broader rollout.

Option A (Proceed with risk identification and prevention): Risk assessment (e.g., FMEA) should precede implementation, not follow it.

Option B (Report the results to senior leadership): Reporting is premature without evaluating performance.

Option C (Implement the system throughout the organization): Organization-wide implementation follows successful pilot evaluation.

Option D (Evaluate the system's performance): This is the correct answer. The NAHQ CPHQ study guide states, “After implementing a new system, evaluate its performance to assess functionality, user adoption, and outcomes before expanding” (Domain 4).

CPHQ Objective Reference: Domain 4: Performance and Process Improvement, Objective 4.5, “Evaluate new system performance,” emphasizes post-implementation evaluation. The NAHQ study guide notes, “Evaluation ensures systems meet quality goals” (Domain 4).

Rationale: Evaluating performance ensures the EMR system is effective, aligning with CPHQ’s improvement principles.
