  1. P Pharmacologic cases, NP Non-pharmacologic cases. “Total Fields” was calculated by multiplying the total subjects (column 1) by the number of fields per case (column 2); and was used as the denominator to calculate all-field error rates. “Populated Fields” was calculated by multiplying the total subjects per case type by the total number of fields populated for each subject that fell within that category
