Economic cost of secondary postpartum haemorrhage: A case-control study at a tertiary hospital in Australia.

Background: Secondary postpartum haemorrhage (PPH) is a condition which affects 0.2-3.0% of women. Despite its impact on maternal morbidity, there is a lack of understanding of the cost burden of disease.

Aims: To determine the economic cost of secondary PPH in the postpartum period, compared to the costs for women without this diagnosis.

Materials And Methods: Data were prospectively collected on a cohort of 97 women who presented with secondary PPH to the emergency department (ED) between July 2020 and February 2021. A case-control design was then used to compare postpartum cost data from these patients to a group of 97 controls who were matched to maternal demographics, and who did not present with secondary PPH.

Results: For women with secondary PPH, there were significantly more hospital attendances, and postpartum costs were higher for all cost subcategories across ED, admissions, and outpatient attendances (P < 0.0001), compared to controls. The total cost of postpartum care for 97 patients with secondary PPH was $254 377.62 with an average cost per patient of $2622.45, compared to $26 670.46 for 97 controls with an average cost of $274.95 per patient (P < 0.0001). This demonstrates a 9.5-fold increase in postpartum costs per woman with secondary PPH.

Conclusions: Secondary PPH is an under-researched condition which presents a significant cost burden for the health system. Evidence-based guidelines addressing the prevention and management of secondary PPH may assist in minimising this cost burden for both the health service and the patient.
