Obstetric providers (and by affiliation, their practice Web site) were excluded from the final sample if (1) a practice Web site associated with the selected provider was unable to be identified, (2) the primary practice location of the provider selected from Healthgrades.com was not in the target state, (3) the practice did not provide prenatal care as determined from information provided on the practice Web site, (4) the practice appeared to be permanently closed, (5) the practice was duplicative of one already selected in the sample, or (6) the practice had an apparent military affiliation. Practice eligibility was again assessed during the August data collection period, where practices were subsequently removed from the sample if their eligibility had changed.
