Population health management focuses on improving the health outcomes of a specific group by managing and coordinating care across the health continuum. Ensuring timely access to eye examinations for people with diabetes is a prime example of population health management because it targets a specific group (people with diabetes) and addresses a preventive measure (eye exams) to reduce the risk of complications, such as diabetic retinopathy.
Reducing medication errors in a pharmacy (B): While important, this is more related to patient safety and quality improvement in a specific setting rather than population health management.
Reducing turn-around times in the emergency department (C): This improves efficiency but is not directly related to managing the health of a specific population.
Ensuring accurate medication reconciliation for people in hospice care (D): This is critical for patient care but focuses on a specific care process rather than broad population health management.

Implementing a new device, especially for high-risk procedures like chemotherapy, requires proactive risk assessment to prevent potential errors.
Option A (Cause and effect diagram): Also known as a fishbone diagram, this identifies causes of existing problems, not potential risks of a new device.
Option B (Failure mode and effects analysis (FMEA)): This is the correct answer. The NAHQ CPHQ study guide states, "FMEA is a proactive tool used to identify potential failure modes, their effects, and mitigation strategies before implementing new processes or devices" (Domain 1). For a chemotherapy device, FMEA assesses risks like dosing errors or device malfunctions.
Option C (Common cause analysis): This analyzes routine variations, not specific risks of new devices.
Option D (Root cause analysis (RCA)): RCA is reactive, used after an incident, not proactively before implementation.
CPHQ Objective Reference: Domain 1: Patient Safety, Objective 1.5, "Use proactive risk assessment tools," emphasizes FMEA for new processes. The NAHQ study guide notes, "FMEA is critical for identifying risks in high-stakes interventions like chemotherapy" (Domain 1).
Rationale: FMEA proactively identifies and mitigates risks for a new chemotherapy device, aligning with CPHQ's patient safety principles.
