Increased Tdap and Influenza Vaccination Acquisition Among Patients Participating in Group Prenatal Care.

CenteringPregnancy, an alternative to traditional prenatal care, offers additional time between clinicians and patients with the goal of increasing knowledge, understanding, and autonomy in pregnant participants. We investigated whether these women would be more likely to receive recommended Tdap and influenza vaccinations relative to others who received one-on-one traditional prenatal care. Our study employed a retrospective chart review of all women who participated in CenteringPregnancy group care compared to a group of matched women who received only traditional prenatal care at a large, quaternary care referral academic center. We extracted demographic and clinical characteristics from charts that included maternal age during pregnancy care and parity. Outcome variables of interest were influenza and Tdap vaccination status. Compared with traditional obstetrical care patients, women who participated in CenteringPregnancy were 1.7-2.7 times more likely to obtain the Tdap and influenza vaccines. These findings may be attributable to the increased opportunity for patient education and social support offered by the CenteringPregnancy model.
