Table 3. Shock at Admission, Mean Arterial Blood Pressure and Mortality.
Data are presented as median (25th percentile–75th percentile) for continuous variables and number (percentage) of patients for categorical variables. N represents the number of non-missing values. Shock on admission was defined as systolic blood pressure <90mmHg or the need for vasopressors or mechanical support at the time of admission.
| N | Shock at admission (n = 54) |
No shock at admission (n = 134) |
p-value | |
|---|---|---|---|---|
| Baseline NIMAP (mmHg) | 174 | 81 (72–87) | 87 (77–94) | 0.002a |
| Baseline AMAP (mmHg) | 148 | 82 (74–86) | 88 (82–97) | <0.001a |
| Achieved NIMAP (mmHg) | 174 | 80.3 (73.8–88.5) | 83.7 (77.2–90.1) | 0.11a |
| Achieved AMAP (mmHg) | 148 | 82 (73–87) | 88 (82–94) | <0.001a |
| Survival to hospital discharge (%) | 188 | 10 (18%) | 70 (52%) | <0.001b |
| Survival to outpatient follow up (%) | 162 | 6 (12%) | 42 (38%) | <0.001b |
