A clinic implements a new diabetes management protocol. They measure hemoglobin A1c levels for all diabetic patients at baseline and every 3 months. After 1 year, they want to present the data to show whether the protocol improved glycemic control across the patient population. Which of the following is the most appropriate method for displaying this data?
- A)A histogram of A1c values at 12 months
- B)A pie chart showing the proportion of patients at goal
- C)A scatter plot of individual patient A1c values at baseline versus 12 months
- D)A single bar graph comparing baseline A1c to 12-month A1c
- E)A run chart plotting the mean A1c of the population over each quarterGABARITO
Explicação
A run chart plots a measure over time and is the standard quality improvement tool for demonstrating trends. Showing the mean A1c across quarters allows the team to visualize whether the protocol produced sustained improvement over time rather than a single sn... Ver explicação completa e trilha adaptativa →
