Perspectives on Maternal Vaccination from Obstetrical Clinicians: A Qualitative Multi-site Study.

OBJECTIVES: Despite the seriousness of influenza and pertussis, availability of safe and effective vaccines against them, and long-standing maternal vaccination recommendations, US maternal influenza and Tdap vaccination rates have been low. To increase vaccination rates in obstetric offices, it is important to understand clinician perspectives and office processes. We conducted in-depth interviews with nurses and providers on these topics. METHODS: Interviewees worked in obstetric offices in one-of-four participating health systems in NY and CA. We audio-recorded and transcribed 20-30-min interviews. We used predetermined categories to code interviews with Dedoose, then iteratively refined codes and identified themes. RESULTS: We conducted 20 interviews between 4/2020 and 9/2020: 13 providers (physician or nurse midwife) (5 NY, 8 CA); 7 office nurses (6 NY, 1 CA). In almost all offices, patient refusal of influenza vaccine was considered the major vaccination barrier; Tdap was often deferred by patients until post-delivery. Nurse-only visits for either vaccine were rare. Vaccination outside the office was uncommon; few offices systematically documented vaccines given elsewhere in a retrievable manner. Participants emphasized patient education as key to prenatal care, but the number of topics left little time for immunizations. Few interviewees could identify an office "immunization champion," knew their office vaccination rates, or had participated in vaccination quality improvement. Several interviewees indicated that they or another provider were good at persuading hesitant patients, but their method had not been shared with other clinicians. CONCLUSIONS FOR PRACTICE: Multiple practical barriers and maternal vaccine hesitancy limit maternal vaccination. Quality improvement strategies are needed.

Obstetric Provider Attitudes and Office Practices for Maternal Influenza and Tdap Vaccination.

Background: Although maternal vaccination with influenza and tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccines improve health outcomes for pregnant individuals and infants, maternal vaccination rates are low. This study assessed obstetric providers' attitudes and practices related to influenza and Tdap vaccination in four large health systems in New York (NY) and California (CA). Methods: We conducted a cross-sectional survey of all obstetric providers within four health systems (two in NY, two in CA) to evaluate provider attitudes and office systems used for Tdap and influenza vaccination. The survey assessed perceptions of influenza and Tdap vaccination based on the Health Belief Model, and assessed office systems (reminders, prompts, standing orders, and patient education) and communication with pregnant patients related to influenza and Tdap vaccines. Results: We had 112 responses (52% response rate) for analyses. Respondents strongly supported vaccination during pregnancy but viewed influenza disease as less of a concern for newborns than for pregnant individuals (40% vs. 67% considered influenza disease to be very significant, p < 0.001). Only 84% agreed that giving influenza vaccine in the first trimester is very safe. Patient vaccine refusal was the most commonly named barrier for both influenza and Tdap vaccination. Providers frequently used office system prompts, but did not frequently use standing orders, patient educational materials, vaccine champions, and feedback on vaccination rates. Conclusions: While most providers consider influenza and Tdap vaccination important during pregnancy, there is room for improvement in focusing on the importance of maternal vaccination to the health of the infant, and increasing the use of office systems to improve vaccination during pregnancy.
