To compare the clinical practicability of two bleeding grading systems (BGS) in pregnancy with Immune Thrombocytopenia (ITP). The clinical data of 154 cases were retrospectively analyzed with the 2016 version of the ITP Bleeding Scale (ITP-2016) and the ITP-specific bleeding assessment tool (ITP-BAT). The correlation between the two BGS and the relations among the platelet counts, gestational ages, and disease stages were respectively analyzed. There is no significant difference between the two BGS in the patients’ ages, nor between the newly diagnosed and the persistent group or the chronic group, while the difference between the persistent and the chronic group was significant ( = 0.001; = 0.001). There is a negative correlation between the bleeding grade and platelet count (r = -0.436; r = -0.390), while the correlation between the two BGS was positive (r = 0.921). The proportions of identical scores provided by two different physicians using the two BGS were 94.8% and 93.5%. The difference before and after the treatment were significantly different ( = 0.013; = 0.037). It takes less time to score with the ITP-2016 ( = 0.011). Both systems can be useful for disease evaluations, risk assessments and efficacy evaluations in Chinese pregnant women with ITP. The ITP-2016 takes less time and is more suitable for Chinese pregnant patients with ITP.
