Summary:Postpartum haemorrhage (PPH) is one of the leading causes of maternal morbidity and mortality. Studies have reported an increase in incidence of postpartum haemorrhage in recent years.

We used the database codes to identify patients with PPH, maternal factors, pregnancy-related and delivery-related factors. Significant changes in temporal trends were determined using Mantel-Haenszel test for trend. Multivariable logistic regression analyses were conducted to assess PPH and risk factors. Births complicated by PPH in Switzerland increased from 2.5% in 1993 to 4.5% in 2014 (p
