CDC/CMVDevelopment and Evaluation of a Clinic-Based Screening and Brief Intervention for Changing Behaviors Related to Cytomegalovirus Transmission in Pregnant Women

The study is a randomized single-masked clinical trial of behavioral intervention versus standard care of pregnant women lacking evidence of acute CMV infection that have consented to be screened as part of the Maternal Fetal Medicine Units Network multi-centered randomized clinical trial, in which pregnant women are screened with CMV serology for IgM, IgG, and IgG avidity. Eligible pregnant women will be randomized to one of two treatment groups: Control Group - no intervention Intervention Group - brief intervention and educational materials Written informed consent will be obtained from patients before they can be screened for the study by CMV testing (IgM, IgG, and IgG avidity) as per the protocol for screening in the MFMU study. All women presenting for prenatal care no later than 20 weeks gestational age without a known multifetal gestation are eligible for CMV screening Those with evidence of primary infection will be offered participation in the MFMU randomized trial of CMV hyperimmune globulin to prevent congenital infection. Women lacking evidence of acute infection will be eligible for randomization into this study. Patients must be randomized no later than 20 weeks gestation. If eligible and no more than 20 weeks gestation, the patient will be randomized. If the patient is randomized in the control group, she will continue her routine prenatal care inclusive of the CDC brochure that she received at the time of her venipuncture for serologic screening and assessment of hygiene behaviors. If the patient is randomized into the intervention group, we will deliver a face-face educational intervention during her next routine prenatal visit. In addition to the intervention, the patient will include educational material to take home. Both groups will be assessed for performance of hygiene behaviors as a baseline assessment at the time of consent. A second assessment will occur at least 12 weeks after enrollment during the third trimester between 28-36 weeks of gestation. The follow-up assessment will be completed by a different research assistant from the unblinded educator. A Kessler 10 (K10) survey will also be completed in addition to the baseline and follow-up assessment. The follow-up assessment will take place during the participant's third trimester between 28-36 weeks of gestation, depending on duration of enrollment and likelihood of early delivery. The enrollment duration will vary from approximately 14-20 weeks.
