NAHQ CPHQ Questions Answers

Barcoding technology with electronic documentation at the point of care is primarily designed to reduce medication errors that occur during the administration stage123. This technology, known as Bar-coded Medication Administration (BCMA), provides point-of-care verification of the correct patient and medication3.

When a medication is administered, the healthcare professional scans the barcode on the patient’s identification band and the barcode on the medication. The system then checks the scanned information against the medication order in the patient’s electronic health record. This process helps ensure that the right patient is receiving the right medication at the right dose and at the right time, thereby significantly reducing administration errors1234.

While barcoding technology can also help reduce other types of errors such as dispensing errors3, its impact is most significant on administration errors. Therefore, in the context of the question, the implementation of barcoding technology with electronic documentation at the point of care will most likely reduce administration errors.

The concept of care quality that remains consistent across diverse patient characteristics is rooted in the Institute of Medicine’s (IOM) six aims for healthcare improvement, as outlined in Crossing the Quality Chasm (2001).

Option A (Efficient): Efficient care minimizes waste, not addressing variation across demographics.

Option B (Effective): Effective care delivers evidence-based results, not specifically ensuring consistency across groups.

Option C (Equitable): This is the correct answer. The NAHQ CPHQ study guide states, “Equitable care, as defined by the IOM, ensures quality does not vary due to gender, ethnicity, geographic location, or socioeconomic status” (Domain 4). Equity is one of the six IOM aims, focusing on fairness in care delivery.

Option D (Evidence-based): Evidence-based care relies on scientific evidence, not directly addressing demographic disparities.

CPHQ Objective Reference: Domain 4: Performance and Process Improvement, Objective 4.1, “Apply quality principles to care delivery,” includes the IOM’s equitable care aim. The NAHQ study guide notes, “Equitable care ensures fairness across all patient populations” (Domain 4).

Rationale: Equitable care directly addresses consistent quality across diverse groups, aligning with CPHQ’s improvement principles and IOM standards.

The control chart shows a clear pattern of medication errors increasing above the upper control limit during the early months, indicating a period of instability or special cause variation. After this peak, there is a marked and consistent decline in error rates, falling well below the mean and approaching the lower control limit by the end of the year.

According to The Joint Commission and Institute for Healthcare Improvement (IHI) guidelines on control charts and statistical process control:

When data points fall outside control limits, this indicates special cause variation that warrants investigation.

The sustained decrease below the mean and toward the lower control limit strongly suggests a significant reduction in the medication error rate over time, which is statistically and clinically important.

Option A is premature; improving patient safety is multifactorial and while error rates decreased, meeting a strategic goal requires additional evidence of sustained improvement and outcome measures.

Option B accurately reflects the data trend showing a significant reduction in reported medication errors.

Option C is not supported; while errors increased in spring and summer, the chart does not specify the severity of errors, only the rate.

Option D is incorrect as there is no evidence that reporting of errors improved; instead, errors themselves declined.

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
