- Most codes have expected longitduinal variation across sites, but site-specific differences in code utilization across the time period are visible. For example, C8MSHS uses 242120 (an insulin code) as a second line antidiabetic agent at a much higher rate than the all site average. - There are notable differences between the pediatric institutions and the more adult focused institutions across the time series. N18.1 and N18.2 plots demonstrate that C7 sites use these codes more compared to almost every other participating institution, while they generally use a code like E11.22 less.
