Risk of early OHCA (0–30 days postdischarge) and late OHCA (31–365 days postdischarge) after sepsis admission among the propensity score matched cohorts
| Time interval for OHCA | Sepsis versus non-infected hospitalised patients | Sepsis versus non-sepsis infection-related patients |
| Early OHCA (0–30 days) incidence (1/1000 person-days) | Sepsis: (144/515 726 person-days) Non-infection: (87/516 704 person-days) | Sepsis: (144/516 326 person-days) Non-sepsis: (113/516 856 person-days) |
| Early OHCA (0–30 days) HR (95% CI) | 1.66 (1.27 to 2.16)* P=0.0002 | 1.28 (1.00 to 1.63) P=0.0500 |
| Late OHCA (31–365 days) incidence (1/1000 person-days) | Sepsis: (640/6 174 507 person days) Non-sepsis: (542/6 202 632 person-days) | Sepsis: (640/6 181 807 person-days) Non-sepsis:(566/6 200 964 person-days) |
| Late OHCA (31–365 days) HR (95% CI) | 1.19 (1.06 to 1.33)* P=0.0035 | 1.13 (1.01 to 1.27)* P=0.0294 |
*Means p<0.05.
HR, hazard ratio; OHCA, out-of-hospital cardiac arrest.
