Background: Italian National Immunization Plan (NIP) 2017-2019 has introduced new recommendations regarding immunization practices during pregnancy. In this cross-sectional study, we documented specific knowledge, attitudes, and practices (KAP) in a sample of obstetrician-gynecologists (OBGYN).
Methods: A total of 68 OBGYN (39.7% of males, mean age of 47.7±9.3 years old) compiled a structured online questionnaire. Participants were asked about: knowledge of vaccine issues (both in general and regarding NIP recommendations for pregnant women); actual performance/recommendation of seasonal influenza (SID) and tetanus-diphtheria-acellular pertussis vaccinations (Tdap); risk perception about SID and pertussis. Eventually, a regression analysis was performed in order to identify predictive factors for vaccine propensity.
Results: Although most OBGYN were aware of official recommendations, only 57.4% and 55.9% correctly recalled the appropriate timing for vaccinations shots for SID and Tdap. Overall, 79.4% and 67.6% of participants usually delivered or recommended SID and Tdap to pregnant women, respectively. Main perceived barriers were identified by OBGYN in patients' fear of side effects (89.7%), their low risk perception (82.3%), insufficient awareness of official recommendations among pregnant women (75.0%). Significant predictors of Tdap practice were identified in higher risk perception (OR 6.466, 95% CI: 1.077; 38.803) and better knowledge of official recommendations (OR 7.310, 95% CI: 1.195; 44.704), whereas SID was apparently unrelated with individual characteristics of participants.
Conclusions: Sampled OBGYN were largely favorable towards vaccination of pregnant women. As knowledge of official recommendations was identified as a main predictor of appropriate behavior at least for Tdap practice, future educational interventions could eventually improve immunization rates.
