Understanding the longitudinal plots

These stick plots allow you to track changes in unit-level, CCG or network performance over a period of time for the 'Unadjusted Median HbA1c' audit measure. The NPDA recommends using the median to track year on year progress within the same unit, as the median is less affected by extreme results.

The units/CCGs/networks you select will show as coloured sticks on the plot. A trend towards lower HbA1c is indicative of improvement, and you can use the graph to show whether improvements are in line with national or regional trends, or whether progress towards lower HbA1c has been faster or slower in your unit of interest.
