Conclusion
In today’s climate of limited research funding, it is imperative that obstetric trials determine the benefits and harms of interventions based on a comprehensive set of maternal and fetal-neonatal outcomes considered important by patients and relevant stakeholders. Healthcare researchers should be obliged to ensure that clinical research meets this minimum standard, as mothers and their babies are entitled to care that is based on reliable evidence. We report the development of the Comprehensiveness of Outcome Reporting (COR) Tool, to assist trialists in selecting the most holistic set of patient-centred outcomes, and systematic reviewers in appraising the integrity of trials, which is essential to the appropriate translation of research findings to clinical care and health policy. We hope that its widespread use, will go a long way in ensuring that clinical research in obstetrics is focused on addressing patient-centered outcomes, thereby directly improving the care of mothers and babies.
