Maternal mortality trends in Spain during the 2000-2018 period: the role of maternal origin.

BACKGROUND: The available literature indicates that there are significant differences in maternal mortality according to maternal origin in high income countries. The aim of this study was to examine the trend in the maternal mortality rate and its most common causes in Spain in recent years and to analyse its relationship with maternal origin. METHODS: This was a cross-sectional study of all live births as well as those resulting in maternal death in Spain during the period between 2000 and 2018. A descriptive analysis of the maternal mortality rate by cause, region of birth, maternal age, marital status, human development index and continent of maternal origin was performed. The risk of maternal death was calculated using univariate and multivariate logistic regression analyses, with adjustment for certain variables included in the descriptive analysis. RESULTS: There was a total of 293 maternal deaths and 8,439,324 live births during the study period. The most common cause of maternal death was hypertensive disorders of pregnancy. The average maternal death rate was 3.47 per 100,000 live births. The risk of suffering from this complication was higher for immigrant women from less developed countries. The adjusted effect of maternal HDI score over maternal mortality was OR = 0.976; 95% CI 0.95 - 0.99; p = 0.048; therefore, a decrease of 0.01 in the maternal human development index score significantly increased the risk of this complication by 2.4%. CONCLUSIONS: The results of this study indicate that there are inequalities in maternal mortality according to maternal origin in Spain. The human development index of the country of maternal origin could be a useful tool when estimating the risk of this complication, taking into account the origin of the pregnant woman.

Comparing Infection Profiles of Expectant Mothers with COVID-19 and Impacts on Maternal and Perinatal Outcomes between the First Two Waves of the Pandemic.

During 2020, Coronavirus Disease-19 (COVID-19) incidence fluctuated in two clear waves across the spring and autumn periods. This study was designed to compare the maternal and perinatal clinical outcomes in obstetrics patients with COVID-19 between the two waves of infection in Spain. We conducted an observational, analytical, ambispective cohort study with longitudinal follow-up of mothers with confirmed SARV-CoV-2 infection from different hospitals in our country between March-November 2020. We recruited 1295 pregnant women with SARS-CoV2 infection from 78 hospitals, 846 (65.3%) of whom were diagnosed during the first wave and 449 (34.7%) during the second wave. Our results show that patients developing COVID-19 during the first wave had more symptoms at triage, early in pregnancy with greater rates of COVID-19-related maternal morbidity; caesarean section and preterm birth in the first wave. We register two cases of maternal mortality and only during the first wave. Maternal morbidity events showed a strong link to perinatal mortality events in the first wave compared to the second wave, in which maternal morbidity was more associated with pneumonia. Likewise, maternal morbidity showed a strong correlation with perinatal morbidity events in both waves. We describe the differences between the patients' profiles and management between the two waves and related to maternal and perinatal outcomes. Differences were also observed in the management of pregnant women with COVID-19. Thus, there were fewer caesarean sections, and maternal and perinatal morbidity events were reduced in the second wave, while the impacts of respiratory symptoms and their severity, including a greater need for maternal treatment, were greater in this last period. Identifying the impact that changes in the profile as well as in the treatment have on maternal-perinatal morbidity and mortality will help improve the well-being of our patients and their newborns.

A New Multiplatform Model for Outpatient Prenatal and Postpartum Care in a Cohort of COVID-19-Affected Obstetric Patients.

Spain was one of the epicenters of the first wave of the COVID-19 pandemic. We describe in this article the design and results of a new telephone-and-telematic multiplatform model of systematic prenatal and postpartum follow-up for COVID-19-affected women implemented in a tertiary reference hospital in Madrid. We included patients with RT-PCR-confirmed COVID-19 during pregnancy or delivery from 10 March 2020 to 15 December 2020. We had a total of 211 obstetric patients: 148 (70.1%) were tested at the onset of suspicious clinical manifestations and 62 (29.4%) were tested in the context of routine screening. Of all the patients, 60 women (28.4%) were asymptomatic and 97 (46%) presented mild symptoms. Fifty-one women (24.2%) were admitted to our hospital for specific treatment because of moderate or severe symptoms. We had no missed cases and a good adherence. The mean number of calls per patient was 2.3. We performed 55 in-person visits. We analyzed the complexity of our program over time, showing a two-wave-like pattern. One patient was identified as needing hospitalization and we did not record major morbidity. Telemedicine programs are a strong and reproducible tool to reach to pregnant population affected by COVID-19, to assess its symptoms and severity, and to record for pregnancy-related symptoms both in an outpatient regime and after discharge from hospital.
