“…The unit of measure for ABC was not uniform for all articles. The units of ABC were standardized to 1000 patient days (DPDs) [ 21 – 23 , 25 , 30 , 31 , 35 , 37 , 40 , 41 , 44 , 46 , 49 – 52 , 55 – 61 , 64 – 68 , 77 ] and 100 patient days (DPDs) [ 20 , 26 – 29 , 32 – 34 , 36 , 38 , 39 , 42 , 43 , 45 , 53 , 69 , 70 , 73 , 76 ], but in addition, DIDs [ 30 , 40 , 47 , 48 , 56 , 59 , 65 , 66 , 68 , 71 , 72 , 74 , 75 ], grams [ 24 ], and average/percentage trend [ 54 , 62 ] were used to measure ABC. Accordingly, about 948017.9 DPDs (904622.9 standardized per 1000 patient days and 4339.5 per 100 patient days) and 4108.6 DIDs were reported, but about 173616.9 and 99800 were reported in average consumption and in grams, respectively.…”
