NAHQ CPHQ Actual Questions

A scatter diagram is a graphic representation of the relationship between two variables12. It is used to test a theory that the two variables are related and to assess the strength, trend, and shape of that relationship2.

A Pareto chart is a type of bar chart that shows the frequency or impact of different causes or problems in descending order, along with a line graph that shows the cumulative percentage of the total3. It is used to identify the most significant factors among a large number of potential causes or problems3.

A control chart is a type of line chart that shows how a process changes over time, with upper and lower limits that indicate the range of acceptable variation4. It is used to monitor and control a process and to detect special causes of variation that may indicate problems or improvement opportunities4.

A histogram is a type of bar chart that shows the frequency distribution of a singlevariable in a data set5. It is used to summarize and display the shape and spread of the data and to identify outliers or gaps5.

Based on these definitions, the best tool to use for the outpatient medical clinic’s purpose is a scatter diagram, as it can show whether there is a relationship between lack of available transportation and the number of times patients do not keep appointments, and how strong or weak that relationship is. The other tools are not suitable for this purpose, as they do not show the relationship between two variables. References: 1: Scatter Diagram | Digital Healthcare Research 2: Scatter Plot - Clinical Excellence Commission 3: Pareto Chart | Institute for Healthcare Improvement 4: Plotting basic control charts: tutorial notes for healthcare practitioners 5: Histogram | Institute for Healthcare Improvement

Detailed Explanation:

A spaghetti chart visually represents the physical path taken by staff or patients, helping identify inefficiencies, redundancies, and wasted movement.

Option B: Identify redundancies and wasted movement

Spaghetti charts highlight inefficiencies by mapping out excessive or unnecessary movement in the workflow.

Quality indicators are categorized as structure, process, or outcome measures based on their focus within the healthcare delivery system.

Option A (Satisfaction): Satisfaction measures patient or staff perceptions (e.g., survey scores), not objective measures like waiting times, which are operational.

Option B (Process): This is the correct answer. Clinic waiting times are a process indicator, as they measure the efficiency of care delivery processes (e.g., patient flow, scheduling). NAHQ CPHQ study materials classify waiting times as a process measure, reflecting how care is delivered.

Option C (Outcome): Outcome indicators measure the results of care (e.g., mortality, infection rates), not the processes leading to those outcomes.

Option D (Structural): Structural indicators focus on resources or infrastructure (e.g., staffing levels, equipment), not operational processes like waiting times.

An internal customer is someone within the organization who relies on the output of a process or service to perform their duties. In the context of a skilled nursing facility, the nurse completing the initial assessment is considered aninternal customer of the admission process. The nurse depends on the accurate and timely completion of the admission process to assess the patient's condition and plan care accordingly.

Patient’s spouse and family (A): They are external customers who interact with the facility but are not part of its internal processes.

Insurance company (C): This is an external entity involved in the payment process, not an internal customer.

Patient being admitted (D): The patient is the end-user of the services provided but is considered an external customer.
