Background: Concerns about virus spread during surgery contributed to changes in the clinical management of ectopic pregnancies (EP) during the COVID19 pandemic. Objective: To compare published data on EP management prior versus during the COVID-19 pandemic and evaluate any difference in the management, rupture rate and complications where Early Pregnancy Unit (EPU) structures exist. Search strategy: We performed a systematic review of the literature using a keyword strategy based on our PICO criteria. Selection criteria: We included studies which recruited women diagnosed with ectopic pregnancy and compared the management during and prior the COVID-19 pandemic peak. Data collection and Analysis: Three independent reviewers screened the literature and extracted the data. Meta-analysis of the data was performed on Revman. Main Results: Our search yielded 34 studies; 12 were included in our meta-analysis (3122 women). We found no difference in the type of management of EP between the pre-Covid and Covid cohorts [2714 women, OR 0.99(0.63-1.55), p=0.96, I2=77%]. We observed a non-statistically significant reduction of surgical management within the EPU branch ([OR 0.47(0.19-1.13), p=0.09, I2=81%]). There was no difference in the ectopic rupture rate in units with EPU [OR= 0.66 (0.33-1.31), p=0.24, I2=37%]. In contrast, in non-EPU (NPEU) the risk of ruptured EP [OR=2.86(1.84-4.46), p<0.01 I2=13%] and complications [OR=1.69(1.23-2.31), p=0.001, I2=45%] were increased. Conclusions: The worldwide trend was not reflected in the UK suggesting that EPU may have contributed to prompt diagnosis and safe management of EP. Funding: No funding was received.

Objective: to describe the impact of COVID-19 on the management of patients with ectopic pregnancy. Design: a multicentre study comparing outcomes from a prospective cohort during the pandemic [Covid-ectopic pregnancy registry (CEPR)] compared to an historical pre-pandemic cohort [non-Covid ectopic pregnancy registry (NCEPR)]. Setting: five London university hospitals. Population and Methods: consecutive patients diagnosed clinically and/or radiologically with ectopic pregnancy (March/2020-Aug/2020) were entered into the CEPR and an exploratory matched analysis was performed comparing results to NCEPR patients (January/2019-June/2019). Main outcome measures: patient demographics, management (expectant, medical and surgical), length of treatment, number of hospital visits (non-surgical management), length of stay (surgical management) and 30-day complications. Results: 341 patients met inclusion: 162 CEPR and 179 NCEPR. A significantly higher percentage of women underwent non-surgical management versus surgical management in the CEPR versus NCEPR (58.6% [95/162] vs 72.6% [130/179]; p= 0.0084]. Amongst patients managed with expectant management the CEPR had a significantly lower mean number of hospital visits compared to NCEPR [3.6 [SD 1.4] vs 13.7 [SD 13.4], p= 0.0053]. Amongst patients managed with medical management, the CEPR had a significantly lower mean number of hospital visits [NCEPR 6.4 [SD 2.3] vs 8.8 [SD 3.9], p= 0.0014]. There was no observed difference in complication rates between cohorts. Conclusion: women were found to undergo significantly higher rates of non-surgical management during COVID-19 first wave vs NCEPR cohort. Women managed non-surgically in CPER cohort were also managed with fewer hospital attendances. This did not lead to an increase in observed complications rates.
