For the collection of outcomes data, standard, well-validated outcomes instruments have been used such as the data harmonization criteria established by Co-Lab, the reVITALize data definitions validated by the American Congress of Obstetricians and Gynecologists, and the common data points suggested by the Women's Health Registries Alliance. Using these instruments helps ensure that all basic data captured by the Registry will be compatible and interoperable across all registries and biobanks that may share research data. Beyond those instruments, the remaining questions have been formulated based on the input of the Registry's volunteer Scientific Advisory Council with input from patients and a review of the Foundation's Community Forum and social media networks where patients' research questions are typically expressed. These validation efforts, already voluntarily undertaken, demonstrate the Foundation's intention to maximize the use of its Registry and its willingness and commitment to participate in networks that will amplify the Registry's research potential.
