Impact of a Maternal Medicine Hub on post-partum haemorrhage in women with inherited bleeding disorders: A retrospective service evaluation.

We investigated the impact of the Maternal Medicine Network Hub, established at our centre in 2019, on post-partum haemorrhage (PPH) management in women with inherited bleeding disorders (IBDs). Data from 63 patients with IBDs between 2020 and 2023 were compared to a general obstetric cohort. Specific data collected included haemoglobin levels, estimated blood loss, and PPH severity. Post-partum haemorrhage rates above 500 mL and 1000 mL were significantly higher in the IBD group (p = .02 and p = .002, respectively). However very severe PPH (>1500 mL) also known as massive obstetric haemorrhage (MOH) was not significantly different from the general obstetric population (p = .7) in our tertiary centre (The Royal London Hospital). Multidisciplinary care at the Maternal Medicine Hub may mitigate the risk of extreme blood loss (MOH) in women with IBDs. This highlights the necessity of specialised care in improving outcomes for women with IBDs during childbirth.
