Table 4. Sensitivity, Specificity, Negative Predictive Value, and Positive Predictive Value of Different International Statistical Classification of Diseases and Related Health Problems, Tenth Revision Code Abstraction Strategiesa.
| Parameter | Coding performance, % (95% CI) | ||
|---|---|---|---|
| R-code sepsis | Explicit sepsisb | Implicit, including explicit sepsis | |
| Sensitivity | 4.1 (3.6-4.7) | 25.3 (21.8-29.5) | 35.3 (31.3-39.4) |
| Specificity | 96.1 (94.5-98.0) | 90.9 (89.7-92.2) | 68.9 (63.5-74.3) |
| Positive predictive value | 89.7 (87.1-92.3) | 84.4 (79.1-89.7) | 69.2 (68.1-70.1) |
| Negative predictive value | 95.5 (94.9-96.1) | 96.5 (95.9-97.0) | 82.4 (81.5-83.4) |
