CPHQ Certification CPHQ NAHQ Study Notes

A root cause analysis (RCA) is required when a serious incident occurs, such as a "never event" or a sentinel event, which includes a procedure performed on the wrong knee. This type of incident isconsidered a significant error that could cause severe harm to the patient and is a clear indicator of a breakdown in the system that requires thorough investigation through an RCA to prevent recurrence.

Incorrect critical care patient transported to radiology (A): While concerning, this may not reach the threshold for a required RCA unless it led to significant harm.

Admitting a visitor who fell on hospital grounds (B): This incident may require investigation but typically would not trigger an RCA unless the fall resulted in severe injury.

Wrong prescription given to a discharged patient with diabetes (C): This is serious but does not usually require an RCA unless it led to severe consequences.

Detailed Explanation:

The best area for focused quality improvement is determined by comparing the hospital’s infection rate to the state mean infection rate and the confidence interval:

Analysis of Each Procedure

Total Hip Replacement: Hospital infection rate is lower than the state mean (0.4% vs. 0.9%), suggesting a lower risk than average.

Total Knee Replacement: Infection rate is slightly above the state mean (1.1% vs. 1.0%), butwithin a narrow confidence interval (0.8%-1.2%).

ACL Reconstruction: Infection rate aligns with the state mean (1.5%) and has a narrow confidence interval (1.4%-1.6%), indicating less room for reduction.

Total Shoulder Replacement: Hospital rate (1.3%) is higher than the state mean (0.9%), with a broader confidence interval (1.0%-1.6%), suggesting potential variability and room for improvement.

Conclusion

Total Shoulder Replacement (D) has the greatest opportunity for improvement, as its infection rate is notably higher than the state mean, and the confidence interval suggests variability in infection rates.

Providing written medicationinstructions in patients' preferred language is the most effective solution to improve medication adherence among patients with limited English proficiency. Clear, comprehensible instructions are critical for patients to understand how to take their medications correctly, especially for managing chronic conditions like hypertension. Written instructions in the patient's language ensure that they have a reference they can review as needed, reducing the risk of misunderstanding and improving adherence.

Use clinicians with shared language as interpreters (A): While beneficial, this may not always be feasible, and it does not provide patients with lasting reference material.

Use a telephonic interpreter service to communicate instructions (B): This is helpful for immediate communication but does not offer a permanent resource that patients can refer to later.

Implement an automatic refill program for hypertension medications (D): While this can help with adherence, it does not address the language barrier that prevents patients from understanding how to use their medications properly.

In the case of three medication incidents involving narcotics that were near misses, the best tool to identify influencing factors is a Root Cause Analysis (RCA). RCA is a systematic process used to investigate and understand the underlying causes of adverse events or near misses. The goal is to identify contributing factors and underlying system issues that need to be addressed to prevent future occurrences. RCA is particularly suited for situations where an incident has already occurred and the organization needs to understand how and why it happened.

Report from electronic health record (EHR) (A): While EHR data can provide useful information, it is not a tool for identifying root causes of incidents.

Proactive risk assessment (C): This would be more appropriate before incidents occur, not after near misses.

Nominal group technique (D): This is a group decision-making process and is less suited for detailed analysis of incidents compared to RCA.
