The main composite outcome of severe morbidity\/mortality included death, sepsis, need for transfusion, hysterectomy and systemic or organ failure, identified by diagnostic and procedure codes from hospitalisation files. Severe morbidity\/mortality due to ectopic pregnancy were expressed as incidence ratios among women of reproductive age (15\u201364 years) and among women hospitalised for ectopic pregnancy. Comparisons were made between 1987\u20131991 (reference) and 2010\u20132014 using ratios of incidence ratios (RR) and ratio differences (RD).
