NAHQ Updated CPHQ Exam Questions and Answers by koby

The best measurement to document improvement in the process of addressing delays in diagnostic test result availability is turnaround time. Turnaround time measures the total time from when a diagnostic test is ordered to when the results are available to the ordering provider. This directly reflects the efficiency of the process and the impact of any improvements made to reduce delays.

Lost specimen rate (A): This measures a different aspect of the process (specimen handling), not the speed of result availability.

Average length of stay (C): This is a broader measure that may be influenced by many factors beyond diagnostic test turnaround time.

Provider satisfaction (D): While important, it is a subjective measure and may not directly reflect process efficiency improvements.

Reviewing the Control Chart DataThe control chart shows"Events/Bed Day" over time, with the Upper Control Limit (UCL), Lower Control Limit (LCL), and a center line (CL) marking the baseline average of the process before the intervention.

Identifying the Impact of the New Process

The intervention to reduce events per bed day was implemented on January 7.

Following this date, there is a noticeable and consistent decrease in the number of events per bed day, with data points gradually moving downward.

Eventually, the values settle well below the original center line, indicating a decreasing shift in the process.

Differentiating Between Trends and Shifts

A shift is characterized by a sustained change in process level, often due to a successful intervention, as seen here with lower event rates maintained over time.

In this case, the shift is in a favorable direction, as the targeted events per bed day have reduced significantly and consistently.

A trend would indicate a continuous movement in a direction, but this chart shows that after an initial decline, the process stabilizes at a lower rate.

ConclusionSince the process has demonstrated a decreasing shift, indicating improvement and reduced events per bed day, the correct recommendation is to continue the process, as it appears successful in achieving the goal.

To ensure safe transitions of care, a quality professional should focus on evaluating the processes for discharges and transfers (Answer A). This approach involves examining theprotocols and procedures that are in place for discharging patients from one level of care to another, such as from a hospital to a skilled nursing facility or home. Evaluating these processes helps identify potential gaps, inconsistencies, or risks that could compromise patient safety during transitions. It also ensures that all necessary information, including medication lists, follow-up care instructions, and patient education, is communicated effectively between care providers.

The other options are important aspects but do not encompass the entire scope of ensuring safe transitions:

Auditing documentation of patient discharge summaries (B) focuses only on the documentation aspect, not the overall process.

Reviewing patient feedback abouttransfers to skilled nursing facilities (C) is valuable but limited to patient perceptions rather than assessing the entire transition process.

Assessing case management discharge and transfer records (D) looks at specific records but may miss broader process issues.

In the Define phase of the DMAIC (Define, Measure, Analyze, Improve, Control) process, the quality manager identifies and prioritizes the problems to be addressed. This phase involves defining the project goals, scope, and customer requirements, which sets the direction for the subsequent phases.
