The median is the value that’s exactly in the middle of a dataset when it is ordered12. It’s a measure of central tendency that separates the lowest 50% from the highest 50% of values2. The steps for finding themedian differ depending on whether you have an odd or an even number of data points123.

Based on the data provided in the image, we can calculate the median by arranging the vaccine counts in ascending order and finding the middle value. The counts in ascending order are: 5, 10, 16, 18, 30, 55, 71, 90, 114, 144, 195, and 200. Since there are an even number of data points (12), we take the middle value directly without averaging two middle values. So here it is option B - “55”. This is consistent with the principles of median calculation123.

When a performance improvement coordinator faces challenges in keeping a team focused on its goal of decreasing patient waiting times, the first step should be to assess the composition of the team. The effectiveness of a team largely depends on having the right mix of members with the necessary skills, expertise, and perspectives to tackle the problem at hand.

Importance of Team Composition: A well-composed team should include members who are directly involved in the process being improved (e.g., clinicians, administrative staff), as well as those with the expertise in data analysis, quality improvement methodologies, and patient flow management. If the team lacks key stakeholders or if there is an imbalance in expertise, it can lead to misaligned goals, ineffective problem-solving, and poor engagement.

Role of Other Factors:

B. Attendance at team meetings is important for maintaining momentum but does not directly address the underlying issues that could be affecting the team's focus or effectiveness.

C. Amount of data collected is crucial for making informed decisions, but excessive data without proper analysis can overwhelm a team. It is more of a secondary factor.

D. Method of data collection is important for ensuring data accuracy and reliability, but this would typically be assessed after ensuring the team is properly composed to analyze and use the data effectively.

Initial Assessment: By first evaluating the composition of the team, the team leader can ensure that all necessary viewpoints and skills are represented, which is fundamental for addressing any process improvement challenge effectively.

Detailed Explanation:

For a large population, a simple random sample of 400 charts would be sufficient to obtain representative data for statistical analysis:

Option B:Selection of 400 charts using a simple random sampling method

Simple random sampling ensures each patient has an equal chance of selection, providing unbiased and representative results while being more manageable than reviewing all 8,000 records.

Option A: Selection of patients who had a visit during the last month of the year

This could lead to biased results, as it would not be representative of visits throughout the year.

Option C: Selection of 800 patients using a snowball sampling method

Snowball sampling is typically used for hard-to-reach populations and is not appropriate for this scenario.

Option D: Selection of the entire population

Auditing all records would be time-consuming and unnecessary when a statistically valid sample can provide reliable results.

Explanation: The ability to moderate a work group (C) is the most important facilitator characteristic, ensuring effective collaboration and progress. Selecting members (A) and knowledge of mental health (B) or levels of care (D) are secondary. NAHQ prioritizes moderation skills.
