Aims: To determine changes in the use of telehealth and face-to-face consultations for antenatal care (ANC) associated with the COVID-19 pandemic and to identify the groups of women most affected. Materials and Methods: Routine administrative data from three public hospitals in a Local Health District in New South Wales, Australia, were analyzed. Data from 19,171 women who gave birth before the pandemic started (January 2018-January 2020) were compared with data of 5,479 women who gave birth after the pandemic started (December 2020-June 2021). Results: One in eight antenatal services after the pandemic started was a telehealth consultation. The average number of telehealth consultations per woman increased by 0.6 (0.7-1.3, adjusted incidence rate ratio [IRR] = 1.71, p < 0.001), while face-to-face visits decreased by 1.4 (10.6-9.2, adjusted IRR = 0.87, p < 0.001), resulting in an overall reduction of 0.8 (11.3-10.5, p < 0.001) services (7.1%). The increase in telehealth consultations was evident in all groups, but was greatest among women attending the smallest hospital, younger women, and Indigenous women. Most groups of women experienced a reduction in the number of face-to-face and total consultations, but the greatest reductions were among women who attended the largest hospital, received shared care, were older than 35 years, or had conceived through in vitro fertilization. Conclusions: Use of telehealth accounted for a small proportion of total ANC services; its increase did not compensate for the reduction in face-to-face visits, which might have resulted from the lack of suitable equipment, access to facilities, and skills or willingness to engage in telehealth. Ultimately there was an overall reduction of service utilization, which was not uniform among different groups of women.
