The data in the table shows that Department C has the lowest compliance rate in pain management at 65%, which is well below the organization's goal of a 90% mean compliance rate. This indicates that pain management presents the greatest opportunity for improvement. Focusing on pain management in Department C could yield significant gains in overall patient care and satisfaction, as managing pain effectively is a critical component of quality care.
* Patient flow (A): Although Department C also has low compliance in patient flow, pain management has the lowest compliance rate, making it a higher priority.
* Environment of care (B): Compliance rates are higher in this focus area, especially in Department B.
* Infection prevention (D): Compliance rates are generally higher across all departments in this area, so it is not the most pressing issue.

The Ishikawa diagram, also known as a fishbone diagram or cause-and-effect diagram, is the best tool to determine the root cause of variations in a process. This diagram helps teams visually map out all potential causes of a problem, categorizing them into major factors such as methods, machinery, materials, and people.
By exploring these potential causes systematically, teams can identify the root causes of variations and focus their improvement efforts accordingly.
* Histogram (A): A histogram is used to display the distribution of data points but does not help in identifying root causes.
* Shewhart chart (C): Also known as a control chart, it monitors process stability over time but is not specifically for root cause analysis.
* Scatter plot (D): A scatter plot shows relationships between two variables but does not identify root causes of variations.

Explanation: RCA identifies system factors (C), such as process or communication flaws, causing a sentinel event to prevent recurrence. Retraining (A) and process redesign (B) are potential outcomes, not RCA components. Reporting to accrediting bodies (D) follows RCA. NAHQ emphasizes system factor identification in RCA.

The median is the middle value in a data set when the values are arranged in ascending or descending order.
In the case of the non-case/care managed patients, when we arrange the Length of Stay (LOS) in ascending order, we get 7, 8, 9, 10, and 19. Since there are 5 data points, the median is the third value, which is 9.
