| Outcomes | ePAS (n = 189) | uPAS (n = 54) | Pvalue |
|---|---|---|---|
| Primary | |||
| RBC units transfused, median [IOR] | 2 [0–5] | 4 [1–6] | .03a |
| Secondary | |||
| EBL, L, median [IOR] | 1.7 [1.2–3.0] | 2.4 [1.4–3.0] | .04a |
| Other | |||
| Platelet units transfused, median [IOR] | 0 [0–0] | 0 [0–1] | .01a |

| Crystalloid infusion, L, median [IQR] | 3.6 [2.8–4.5] | 3.5 [2.8–4.5] | .74 |
| Length of hospital stay, days, median [IQR] | 5 [4–7] | 4 [3–6] | .02a |
| Reoperation, n, % | 4 (2.1) | 1 (1.8) | .99 |
| Readmission, n, % | 3 (1.6) | 4 (7.4) | .04a |
| Unintentional cystotomy, n, % | 7 (3.7) | 2 (3.7) | .99 |
| Vesicouterine fistula, n, % | 2 (1.1) | 0 | .99 |
| Acute kidney injury, n, % | 0 | 0 | — |
| DVT or PE, n, % | 0 | 0 | — |
| DIC, n, % | 22 (11.6) | 5 (9.3) | .62 |
| Maternal death, n, % | 1 (05) | 1 (1.8) | .40 |
DIC is calculated as per the definition of the International Society of Thrombosis and Homeostasis. Variables are reported as median [IQR] (Mann-Whitney U test) and n (percentage) (χ2/Fisher exact test).
DIC, disseminated intravascular coagulation; DVT, deep vein thrombosis; EBL, estimated blood loss; FFP, fresh-frozen plasma; ICU, intensive care unit; PAS, placenta accreta spectrum; PE, pulmonary embolism; RBC, red blood cell.
