Background: The utility of instantaneous evaluation of coagulation during primary postpartum haemorrhage (PPH) is paramount in the context of empirical blood product transfusion-related risk of dilutional and consumptive coagulopathy and circulatory overload. Methods: A profound screening of electronic databases till August 15, 2022 was carried out after being enlisted in PROSPERO (CRD42021275514). Randomized control studies, comparative cohort studies, and cross-sectional studies comparing point-of-care viscoelastic test guided blood product transfusion with empirical transfusion in patients with PPH were included. Results: We retrieved five studies, with a total of 1914 parturient with PPH. Patients receiving transfusion based upon point of care viscoelastic tests had lesser risk of having emergency hysterectomy (Odds ratio (OR) = 0.55, 95% CI 0.32–0.95, I2 = 7%), transfusion-associated circulatory overload (TACO) (OR = 0.03, 95% CI 0.00–0.50), reduced transfusion of fresh frozen plasma (OR = 0.07, 95% CI 0.04–0.14, I2 = 89%), platelets (OR = 0.51, 95% CI 0.28–0.91, I2 = 89%), packed red blood cell transfusion (OR = 0.70, 95% CI 0.55–0.88, I2 = 89%), and had better cost-effective treatment [Mean difference (MD) = −357.5, 95% CI − 567.75 to −147.25, I2 = 93%] than patient received empirical transfusion. However, there was no significant difference in the requirement of ICU admissions (OR = 0.77, 95% CI = 0.46–1.29, I2 = 82%). No mortality was detected across the studies. Conclusions: Point of care viscoelastic assessment guided transfusion in PPH confederates with reduced morbidity. Nevertheless, more studies on the triggering values for transfusion, long-term survival, and cost-benefit in patients with PPH are warranted to establish its utility.
