What clinicians care about
- Average over a given time period: clinicians want to immediately see what the patient's average blood pressure has been, over a certain time period.
- Highest and lowest systolic and diastolic over a time period: it is also helpful for clinicians to see what the 'range' has been over a specific time period - both for systolic and diastolic blood pressure.
- Clinicians are also thinking: how do the above numbers compare to the patient's goal?
- Consider making the patient's goal very clear on the graph; usually the upper limit of the goal is most important
- Systolic and diastolic usually appear as two overlaid plotted line graphs
- Heart rate is sometimes useful, but many clinicians have told us they don't need to see it. Consider making it an optional component of the graph.
- While interacting with the graph to get detailed readings, consider allowing the user to view blood pressure as one number (e.g. 145/72) instead of forcing them to look in two locations to mentally put together the reading ("let's see, systolic was 145 and...diastolic was 72.")
- Use colors and weights to help indicate where there is and is not data on the graph
