NAHQ CPHQ - Certified Professional in Healthcare Quality Examination

Human factors engineering is a science that uses a systems approach to consider human psychological, social, physical, and biologic characteristics and applies the information to design equipment, processes, and environments to optimize human performance, health, and safety1.

One of the applications of human factors engineering is forcing functions, which are design features that prevent users from making errors or performing unsafe actions2. For example, a forcing function can prevent a user from inserting a wrong key into a lock, or plugging a wrong device into a socket.

In the case of the defibrillator pads, a forcing function could have prevented the delay by making the pads incompatible with the wrong defibrillator, or by alerting the user of the mismatch before attempting to use the device. This would have ensured that only the correct pads were used with the correct defibrillator, and avoided the potential harm to the patient.

The other options are not applications of human factors engineering, but rather methods or strategies that can be used to improve quality and safety in health care. Checklists are tools that help users remember and follow a series of steps or tasks3. Resiliency efforts are actions that help users cope with and recover from adverse events or situations. Usability testing is a process that evaluates how easy and effective a product or system is to use by the intended users. References: 1: Human Factors in Healthcare | SpringerLink 2: Human Factors Engineering | PSNet 3: Checklist Use in Healthcare: A Practical Guide to Improving Quality and Safety : Resilience in Healthcare: A Systematic Review and Synthesis of the Literature : Usability Testing of Medical Devices

Reporting infection control indicators to a governing body requires a tool that clearly shows trends or improvements over time to demonstrate progress.

Option A (Scatter plot): Scatter plots show relationships between variables, not temporal trends, making them unsuitable for infection control trends.

Option B (Run chart): This is the correct answer. The NAHQ CPHQ study guide states, “Run charts display data over time, making them ideal for demonstrating trends and improvements in indicators like infection rates” (Domain 2). They are simple and effective for governing body reports.

Option C (Frequency plot): Frequency plots (e.g., histograms) show data distribution, not time-based trends.

Option D (Pie chart): Pie charts show proportions, not changes over time, making them inappropriate for improvement trends.

CPHQ Objective Reference: Domain 2: Health Data Analytics, Objective 2.3, “Select appropriate data display tools,” identifies run charts for temporal data. The NAHQ study guide notes, “Run charts are preferred for reporting performance trends to leadership due to their clarity and focus on change over time” (Domain 2).

Rationale: Run charts effectively demonstrate improvements in infection control indicators by showing trends, aligning with CPHQ’s data visualization principles for leadership reporting.

The term “surveillance” in public health is defined as the ongoing, systematic collection, analysis, and interpretation of health-relateddata. This process is essential to the planning, implementation, and evaluation of public health practice1. Therefore, the collection, analysis, and interpretation of data for planning, implementing, and evaluating health programs is referred to as “surveillance”. References: 1

Detailed Explanation:

The storming stage involves conflict and differing opinions, which can lead to premature dissolution if not managed effectively.

Option B: Storming

During this stage, teams often experience disagreements, which can lead to dissolution if members cannot resolve conflicts.

Detailed Explanation:

The CDC National Center for Health Statistics collects and reports data on health outcomes, including infant mortality causes, making it the best resource for this information.

Option B: CDC National Center for Health Statistics

This center provides comprehensive data on infant mortality rates and causes.

The IOM’s Crossing the Quality Chasm (2001) outlines six aims for improving healthcare: safe, effective, patient-centered, timely, efficient, and equitable.

Option A (Low costs): Low costs are not one of the six aims, though efficiency indirectly addresses cost by reducing waste.

Option B (Population-centered): Population-centered is not an IOM aim; patient-centered care focuses on individual needs, not populations.

Option C (Effective): This is the correct answer. NAHQ CPHQ study materials cite effective care—delivering evidence-based care that achieves desired outcomes—as one of the six IOM aims.

Option D (Coordinated): Coordinated care is a component of patient-centered or efficient care but is not explicitly listed as one of the six aims.

Implementing significant changes within an organization often encounters resistance due to various factors. Force field analysis is a decision-making tool developed by Kurt Lewin that helps identify and analyze the forces that support or oppose a proposed change. By understanding these forces, organizations can develop strategies to strengthen the driving forces and mitigate the restraining forces, thereby increasing the likelihood of successful change implementation.

The process of force field analysis involves:

Defining the Change: Clearly articulate the proposed change or solution.

Identifying Driving Forces: List factors that support the change,

Effective communication of quality improvement efforts ensures staff are informed, engaged, and motivated to contribute to initiatives, requiring clear, accessible, and relevant information.

Option A (Report results of key quality measures at quarterly staff meetings): Quarterly meetings limit frequency and reach, potentially missing staff who cannot attend, making this less effective.

Option B (Instruct staff to review hospital’s performance data on the Medicare website): Directing staff to external sources is passive and unlikely to ensure engagement or understanding of internal efforts.

Option C (Email the quality improvement committee meeting minutes to all staff): Meeting minutes are detailed and may not be easily digestible or relevant to all staff, reducing effectiveness.

Option D (Send updated scorecards that show the results of key indicators): This is the correct answer. The NAHQ CPHQ study guide states, “Scorecards provide a concise, visual summary of key performance indicators, making them an effective tool for communicating quality improvement progress to staff” (Domain 3). Regular scorecards ensure broad, consistent, and actionable communication.

CPHQ Objective Reference: Domain 3: Organizational Leadership, Objective 3.4, “Develop communication strategies for improvement initiatives,” emphasizes using clear, visual tools like scorecards to engage staff. The NAHQ study guide notes, “Scorecards are effective for sharing performance data in a way that is accessible and motivating” (Domain 3).

Rationale: Scorecards deliver targeted, visual data regularly, ensuring staff across roles are informed and engaged, aligning with CPHQ’s emphasis on effective communication for quality improvement.

DMAIC (Define, Measure, Analyze, Improve, Control) is a Six Sigma methodology for process improvement, with each phase serving a specific purpose.

Option A (Measure): The Measure phase collects baseline data to understand current performance, not sustain improvements.

Option B (Analyze): The Analyze phase identifies root causes, not focused on sustaining new processes.

Option C (Improve): The Improve phase implements solutions, but does not ensure long-term sustainability.

Option D (Control): This is the correct answer. The NAHQ CPHQ study guide states, “The Control phase of DMAIC establishes monitoring systems and standardizes processes to sustain improvements over time” (Domain 4). Tools like control charts and standard operating procedures ensure performance is maintained.

CPHQ Objective Reference: Domain 4: Performance and Process Improvement, Objective 4.3, “Use structured improvement methodologies,” includes DMAIC’s Control phase for sustainability. The NAHQ study guide notes, “Control ensures improvements are sustained through ongoing monitoring and standardization” (Domain 4).

Rationale: The Control phase is designed to maintain process performance, aligning with CPHQ’s focus on sustainable improvement.

Detailed Explanation:

A quality professional often acts as a group facilitator, guiding discussions, promoting engagement, and keeping the team focused on improvement goals.

Option C: Group facilitator

Facilitators ensure smooth team interactions and adherence to the project scope, promoting collaborative problem-solving.

Understanding the Control Chart ComponentsThis control chart shows the median delay over time (by week), with control limits (UCL - Upper Control Limit, LCL - Lower Control Limit) and a center line (CL) indicating the process average before the intervention. Control charts like this one are used to determine whether an intervention has led to a significant change in process performance.

Analyzing the Data Before and After the Intervention

From weeks 1 to 19, before theintervention, the process appears to fluctuate around the control limits, with several points near the upper control limit, indicating higher variation and a generally stable process around a higher median delay.

After week 20, following the intervention, the data points show a clear shift downward, consistently staying below the previous control line (CL). The process median delay has notably reduced, and all data points fall within a new, lower range.

Conclusion Based on the Control Chart

The consistent reduction in median delay and the clustering of data points below the previous center line indicate a shift in performance rather than mere random variation. This type of change, sustained over multiple weeks, strongly suggests that the intervention had a substantial impact on reducing the delay.

While there may also be a decrease in variation, the primary visible effect is a shift in performance toward lower median delay values.

Rationale for Selecting Answer BThe correct answer is B. The intervention resulted in a shift in performance, as the chart shows a distinct change in the process level post-intervention, indicating an improvement.

TheJoint Commission (TJC) adopted a formal Sentinel Event Policy in 1996 to help health care organizations that experience serious adverse events improve safety and learn from those sentinelevents1. The Sentinel Event Policy explains how The Joint Commission partners with health care organizations that have experienced a serious patient safety event to protect the patient, improve systems, and prevent further harm1. Each accredited organization is strongly encouraged, but not required, to report sentinel events to The Joint Commission1. Organizations benefit from self-reporting in the following ways: The Joint Commission can provide support and expertise during the review of a sentinel event1. Therefore, the answer is B. The Joint Commission (TJC).

Explanation: When a physician challenges the reported number of healthcare-acquired infections (HAIs), the most effective way to demonstrate data validity is to provide transparency into the methodology used to identify and classify infections. NAHQ CPHQ study materials emphasize that standardized criteria, such as those from the CDC National Healthcare Safety Network (NHSN), are used to define HAIs. Sharing the criteria used to classify infections (B) addresses concerns about accuracy and consistency. Options A, C, and D do not directly validate the infection counts.

Engaging meeting participants requires active facilitation techniques to maintain focus, encourage participation, and achieve objectives.

Option A (Assigning a timekeeper among the meeting participants): A timekeeper helps manage time but does not directly engage participants in discussion or decision-making.

Option B (Sending out the meeting agenda one day prior to the meeting): An agenda prepares participants but does not ensure engagement during the meeting itself.

Option C (Using facilitative approaches during the meeting): This is the correct answer. The NAHQ CPHQ study guide states, “Facilitative approaches, such as encouraging input, managing group dynamics, and using interactive techniques, keep participants engaged and productive in meetings” (Domain 3). Examples include asking open-ended questions or using brainstorming.

Option D (Having the support items readily available before the meeting): Support items (e.g., handouts) aid preparation but do not actively engage participants during the meeting.

CPHQ Objective Reference: Domain 3: Organizational Leadership, Objective 3.2, “Facilitate effective meetings,” emphasizes facilitative approaches for engagement. The NAHQ study guide notes, “Facilitation techniques are critical for maintaining participant involvement and achieving meeting goals” (Domain 3).

Rationale: Facilitative approaches actively involve participants, ensuring engagement and productivity, as per CPHQ’s leadership principles.
