Per the NAHQ CPHQ exam blueprint, incidence rates are fundamental epidemiologic measures used to evaluate risk and occurrence of new events over time. Incidence specifically measures new cases of a condition that develop within a defined population during a specified time period.

Option A correctly defines incidence by identifying new cases, specifying a timeframe, and using the population at risk as the denominator. This aligns directly with CPHQ expectations for differentiating incidence from prevalence.

Option C includes all cases (new and existing), which describes prevalence over a period rather than incidence. Option D reflects point prevalence, measuring cases at a single point in time. Option B is mathematically incorrect and does not represent a standard epidemiologic calculation.

The CPHQ framework emphasizes incidence rates for evaluating disease onset, effectiveness of prevention strategies, and population health trends, making Option A the correct and verified response.

When across-functional team is assigned the task of improving a process, such as laboratory reporting time in the emergency room, the first step after identifying the problem is usually to understand the root causes of the problem. A fishbone diagram, also known as a cause and effect diagram or Ishikawa diagram, is a visual tool used to systematically identify and present all possible causes of a certain outcome1234.

In this case, the significant delay in receiving laboratory results is the problem that needs to be addressed. The team would use a fishbone diagram to identify and categorize potential reasons for this delay, such as equipment issues, process inefficiencies, human errors, etc. This step is crucial before developing action plans (Option D) because it ensures that the team’s efforts are directed towards addressing the root causes of the problem, rather than just the symptoms1234.

Options A (Identify the responsible individual) and C (Plot a scatter diagram) are not the immediate next steps in this scenario. Identifying a responsible individual is more about accountability after the root causes have been identified and action plans have been developed. A scatter diagram is a graphical tool used to understand the relationship between two variables and is not typically the next step in process improvement after identifying the problem1234.

Clinical-community partnerships connect healthcare providers with community resources to address social determinants such as housing, food security, and transportation, thereby improving health equity and outcomes (CDC, Addressing Social Determinants of Health, 2023; AHRQ, Community Health Integration, 2023).

Practice transformation and risk stratification are important but less directly target social factors.

Clinical practice guidelines focus on clinical care, not social determinants.

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
