Table 3 Distribution of erroneous outcomes of the detection algorithm of cardiovascular disease or stroke through the records of an electronic medical record
False negative results (FN) n (%) | Proportion | |||
|---|---|---|---|---|
Total errors (FP + FN) (n = 98) | Total FN (n = 32) | CaVD FN (n = 21) | CeVD FN (n = 11) | |
Codes not included in the algorithm | 20 (20.41) | 20 (62.5) | 15 (71.43) | 5 (45.45) |
Event included in the free-text clinical notes, but not coded | 9 (9.18) | 9 (28.13) | 5 (23.81) | 4 (36.36) |
Coded terms not detected | 2 (2.04) | 2 (6.25) | 1 (4.76) | 1 (9.09) |
Erroneous date | 1 (1.02) | 1 (3.13) | 0 (0) | 1 (9.09) |
False positive results (FP) n (%) | Proportion | |||
|---|---|---|---|---|
Total errors (FP + FN) (n = 98) | Total FP (n = 66) | CaVD FP (n = 39) | CeVD FP (n = 27) | |
Dismissed diagnosesa | 43 (43.88) | 43 (65.15) | 33 (84.61) | 10 (37.04) |
