P-charts for teams A, B and C showing the monthly proportion (%, on the y-axis) of women who initiated LARC within 30 days post-abortion. For team B, the data recording was of uncertain reliability before the QIC. Data for teams A and B was extracted from existing electronic health information systems. For team C, data was manually collected from records prior to the QIC. Note the signs of special cause variation, highlighted in red, signalling an improvement in the proportion of women starting LARC in a timely manner. LARC = Long-acting reversible contraception. QIC = Quality Improvement Collaboratives. LS = Learning sessions. p-bar = the average of all observations. LCLp = Lower control limit (for proportions). UCLp = Upper control limit (for proportions)
