Figure: Graph comparing shunt infection rates before and after initial CASIPP implementation, and after changing the skin preparation from povidone-iodine solution to 2% chlorhexidine gluconate in 70% isopropyl alcohol. Respectively, the infection rates were 5.8% (red line), 4.0% (orange line), and 0.0% (green line) (p < 0.0001). There was not only a decrease in the rate of shunt infections, but also a decrease in the variation in the number of shunt infections over time.
