Percent completion of CDAI by week of intervention. The pre-intervention, PDSA Cycle 1, and PDSA Cycle 2 phases are separated by red bars. The dark blue line show sthe proportion of patient encounters with a documented CDAI by week. The upper control limits are not seen (>1). The lower control limits vary as the denominator of patient encounters changed each week. The p-bar shows the average CDAI documentation rate. More than 6 values are seen above the p-bar after Cycle 2 was implemented, indicating a positive improvement
