Table 4.
Orthopaedic POSSUM scores and the stratification of the effect of delay in surgery on patient mortality
| Observed mortality rates risk stratified to total orthopaedic POSSUM score | ||||||
|---|---|---|---|---|---|---|
| POSSUM score | Delay of surgery | Delay of surgery | ||||
| ≤24 h | >24 h | P value | ≤48 h | >48 h | P value | |
| ≤36 | 8.11 % | 8.51 % | 0.63 | 7.69 % | 10.53 % | 0.50 |
| 37–40 | 12.50 % | 35.29 % | 0.25 | 23.81 % | 50.0 % | 0.31 |
| ≥42 | 6.25 % | 28.57 % | 0.096 | 7.41 % | 50.0 % | 0.0092 |
The evidence indicates that an orthopaedic POSSUM score of >42 is indicative of increasing mortality at 48 h
