Co-OPT: consortium for the study of pregnancy treatments

A new collaborative consortium for the study of pregnancy treatments.

Co-OPT study logo

Summary (Research in a nutshell)

50% of pregnant women are prescribed drugs in pregnancy, but there are significant knowledge gaps about the safety, optimum dosage and long-term effects of medications in pregnancy. 

Co_OPT will address these knowledge gaps through individual patient data level meta-analysis and data linkage studies with data extracted from electronic health records and contributed from birth registries, cohort studies and RCTs.

The initial focus of Co_OPT will be on antenatal corticosteroid treatment. With cross-disciplinary expertise, and data from thirteen datasets (1.5million women and their children) Co_OPT will

  • Describe how antenatal corticosteroid treatment is used across a variety of settings.
  • Determine the short and long-term outcomes of antenatal corticosteroids in women and babies who are treated and subsequently deliver at term (unnecessary treatment), or deliver >7 days after administration (inappropriately timed treatment), or receive antenatal corticosteroids to cover early term delivery.
  • Determine characteristics that influence maternal and infant outcomes following ACT, develop predictive models for their use and determine best formulation and dose regimens.
