Setting
Annually, approximately 115,000 women give birth in Sweden. The vast majority of all pregnant Swedish women attend the free of charge maternal health program, including between 9 and 11 antenatal visits in low-risk multiparous and nulliparous pregnancies, respectively. Assessment of the need of additional visits or health care resources, such as specialized maternity care, is determined at the first antenatal visit based on the patient medical history and current disease-status, or later by indication. Essentially all women give birth at hospital-based delivery wards. The Stockholm region has six delivery wards with approximately 28 000 deliveries annually, accounting for approximately one fourth of all deliveries in Sweden.
