The CDC recommends Tdap (tetanus, diphtheria, acellular pertussis) vaccination during pregnancy as a strategy to protect infants against pertussis. Optimal time for the vaccination is between 27 and 36weeks gestation. This project looks at the providers’ as well as the patients’ perspectives as to why some women are not receiving the vaccine. An 8-question survey was sent out to obstetricians to assess physician’s perceptions on barriers to patients receiving the Tdap vaccination in pregnancy. A second survey was then administered to postpartum patients prior to discharge from the hospital. In the survey of obstetricians, 83% universally offered the Tdap vaccination to patients in the third trimester, and 71% of respondents stated that over half of all patients accepted the vaccine. Over half (56%) of physicians answered that they encounter barriers in trying to offer Tdap in their practice, and identified the lack of point of care availability (70%) as the most common barrier. Differences in vaccination rates of women based on different insurance types were noted, and 59% of providers answered that Medicaid patients were less likely to receive Tdap due to reimbursement issues. The patient survey revealed that 65% of patients were offered the vaccine in the third trimester, but only 37% received the vaccine. The reasons cited for not accepting the vaccine were lack of availability of vaccine in the physician’s office (44%), lack of patient understanding as to why the vaccine was important (36%), and concerns about vaccination safety (20%), This project illustrates the differences in obstetricians and patients perception on barriers for Tdap vaccination in pregnancy. This observed difference in the acceptance rates between statements by MD’s and those made by patients is statistically significant (Fisher’s Exact Test, p=0.0002). Strategies to improve vaccination rates must address barriers on both sides.
