A comparison of the performance of UVA, MEWS and qSOFA scores by population subgroups of patients pooled from hospital-based cohort studies conducted in six African countries from 2009 to 2015
| Score | All (n=5573) | HIV serostatus known (n=3402) | HIV-infected (n=2122) | HIV-uninfected (n=1280) | Suspected infection (n=3153) | No diagnosis (n=2420) |
| UVA, AUC (95% CI) | 0.77 (0.75 to 0.79) | 0.78 (0.76 to 0.80) | 0.72 (0.69 to 0.75) | 0.82 (0.77 to 0.87) | 0.75 (0.72 to 0.77) | 0.74 (0.70 to 0.78) |
| MEWS, AUC (95% CI) | 0.70 (0.68 to 0.71) | 0.67 (0.65 to 0.70) | 0.61 (0.59 to 0.64) | 0.69 (0.63 to 0.74) | 0.65 (0.63 to 0.68) | 0.68 (0.64 to 0.72) |
| qSOFA, AUC (95% CI) | 0. 69 (0.67 to 0.72) | 0.69 (0.66 to 0.71) | 0.64 (0.61 to 0.68) | 0.70 (0.63 to 0.76) | 0.68 (0.65 to 0.71) | 0.62 (0.57 to 0.66) |
AUC, area under the receiver operating characteristic curve; MEWS, modified early warning score; qSOFA, quick sepsis-related organ failure assessment; UVA, universal vital assessment.
