Summary

Core outcome sets are an agreed, standardised set of outcomes based on what key stakeholders consider the important outcomes in the management or prevention of a condition. They are crucial to unifying research data from different trials, allowing outcomes to be combined and compared. Core outcome sets in miscarriage prevention and management and ectopic pregnancy have been produced. The final outcomes for miscarriage management are: efficacy of miscarriage treatment, heavy vaginal bleeding, pelvic infection, maternal death, procedural related complications and patient satisfaction. The final outcomes for miscarriage prevention are: pregnancy loss, live birth, congenital abnormalities, fetal growth restriction, gestation at birth, pre-term birth, neonatal or infant death, maternal complications, compliance with intervention, patient satisfaction, maternal hospitalisation and neonatal or infant hospitalisation. The final outcomes for ectopic pregnancy are: treatment success, resolution time of EP, number of additional interventions, adverse events, mortality and severe morbidity and treatment satisfaction.
