When Two Coincidences are a Clue: A Retrospective Cohort Study Regarding the Incidence of Ruptured Tubal Pregnancies in a Northern Italy Hospital During the COVID-19 Pandemic

Background: Undiagnosed ectopic pregnancies are among the main gynecological emergencies, and hemorrhage from an ectopic pregnancy is still the leading cause of maternal mortality in the first trimester. During the first lockdown period in Italy (March–April 2020) and in March 2021 restrictive measures were issued by the Italian government, but their impact on the incidence of ruptured tubal pregnancies remains unknown. Methods: The purpose of this study was to evaluate the impact of restrictive measures for the COVID-19 outbreak on the incidence of ruptured tubal pregnancies at our referral center for endoscopic gynecologic surgery. In particular, the primary outcome was the comparison of the incidence of ruptured tubal pregnancies between the lockdown phases and the other months of the pandemic. For this retrospective cohort study we considered all women examined for tubal ectopic pregnancy at our emergency unit from 1 January 2019 to 30 April 2021. We divided patients into three groups according to the period they were referred to our center: 10 March 2019–10 March 2020 (Pre-Covid period); 11 March–4 May 2020 and 6 March–30 April 2021 (Lockdown periods); 5 May 2020–5 March 2021 (COVID-19 pandemic period without restrictive policies). We compared data acquired during the lockdown phases with data collected both before the COVID-19 pandemic and during the restriction-free COVID-19 period. Results: 31 of 85 women were diagnosed with a ruptured tubal pregnancy. The proportion of ruptured ectopic pregnancies was higher during the lockdown period than the other two periods combined (62.5% vs 30.4%, p = 0.016). Mean gestational age and beta-HCG levels showed the same tendency (7.31 ± 1.25 weeks vs 5.99 ± 1.28 weeks, p < 0.0001; 7392.56 ± 4337.50 mUI/mL vs 4188.36 ± 3235.95 mUI/mL, p = 0.001). There were no differences between the proportion of ruptured pregnancies during the whole COVID-19 pandemic and the months preceding it (45.7% vs 25.6%, p = 0.07). Conclusions: Our study demonstrated that restrictive lockdown policies for the containment of the COVID-19 outbreak are associated with an increased rate of ruptured extrauterine tubal pregnancies.
