time from ER arrival to intervention | Procedure duration | Mortality | Blood transfusion requirements | |
Gross, 2009 | Similar mean time to first operation between hybrid OT group (155 min) versus conventional group (187 min) [P = 0.35] | Not assessed | Similar 30-day mortality between hybrid OT group (17%) versus conventional group (22%) [P = 0.42] | Not assessed |
Loftus, 2020 | Not assessed | Similar median total procedure times in the hybrid OT group (135 min) versus conventional group (133 min) [P = 0.971] | Similar in-hospital mortality in the hybrid OT group (13%) versus conventional group (10%) [P = 0.579] | Decreased median red blood cell (0 vs 1; P = 0.001) and plasma (0 vs 1; P < 0.001) transfusion associated with the hybrid group 4–24 h after arrival |
Carver, 2020 | Shorter time to intervention in the hybrid OT group (82 min), compared to time to angiography (148 min) and time to OT (101 min) in the conventional group [P < 0.05] | Shorter procedure times in the hybrid OT group | Similar in-hospital mortality in the hybrid OT group (14%) versus conventional group (15%) | Lower blood transfusion rate in the hybrid OT group (25%) versus conventional group (16%) [P = 0.04] |
Kataoka, 2016 | Not assessed | Shorter total procedure time in the hybrid OT group (229 min) versus conventional group (335 min) [P = 0.007] | Similar in-hospital mortality in the hybrid OT group (15%) versus conventional group (36%) [P = 0.31] | No significant difference in mean blood transfusion volume during procedure between the hybrid OT group (4174 ml) and conventional OT group (5832 ml) [P = 0.24] |
