AbstractBackgroundSevere maternal morbidity is an indicator for quality of maternal care. Recently, there has been growing interest in identifying which provision factors affect the quality of maternity care. The extent to off-hour delivery on SMM rates contributes to individual or provision factor in Korea has not been studied. This study aimed to determine the relationship between off-hour delivery and SMM during childbirth hospitalization.MethodsThis is a population-based retrospective cohort study. Data were extracted from the Korean National Health Insurance Service-National Sample Cohort for 90 072 cases of delivery in Korea between 2003 and 2013. The main outcome was SMM which was determined using the Center for Disease Control and Prevention’s algorithm. A generalized estimating equation model with log link was performed for the relationship with SMM and day/time of delivery adjusted covariates.ResultsOf the 90 072 delivery cases, 2085 (2.31%) had SMM. Women who were on weekdays at night time or on weekend delivery had a higher risk of SMM compared with those who were on weekdays at daytime (RR 1.26, 95% CI 1.10–1.46, and RR 1.58, 95% CI 1.30–1.93, respectively).ConclusionWeekday at night time or weekend delivery was related to the risk of SMM. Policymakers should provide financial support and systematically allocate adequate human resources and labour facilities in vulnerable areas, as well as during weekends and night times to improve the quality of intrapartum and postpartum maternity care.

Abstract Objective This study aimed to examine whether prenatal biochemical screening analytes are associated with an increased risk of severe maternal morbidity (SMM) or maternal mortality. Study Design This population-based cohort study includes all women in Ontario, Canada, who underwent prenatal screening from 2001 to 2011. Increasing fifth percentiles of the multiple of the median (MoM) for alphafetoprotein (AFP), total human chorionic gonadotropin, unconjugated estriol (uE3), dimeric inhibin-A (DIA), and pregnancy-associated plasma protein A were evaluated. An abnormally high concentration (>95th percentile MoM) for each analyte, individually and combined, was also evaluated. The main outcome assessed was the adjusted relative risk (aRR) of SMM or maternal mortality from 20 weeks' gestation up to 26 weeks thereafter. Results Among 748,972 pregnancies, 11,177 resulted in SMM or maternal mortality (1.5%). Except for uE3, the aRR of SMM or maternal mortality increased in association with increasing fifth percentiles of the MoM for all analytes. AFP (aRR: 2.10; 95% confidence interval [CI]: 1.97–2.25) and DIA (aRR: 2.33; 95% CI: 1.98–2.74) > 95th versus ≤ 5th percentile of the MoM were especially associated with SMM or death. Conclusion Women with abnormally high concentrations of certain prenatal biochemical analytes may be at a higher risk of SMM or death in pregnancy or postpartum.

Objective. To assess quality of life (QOL) in women who experienced a severe maternal morbidity (SMM) event and associated factors, in comparison to those who did not. Study Design. Retrospective cohort study performed at the maternity of the University of Campinas in Brazil, including 801 women with or without SMM, within 6 months to 5 years after delivery. Women were interviewed by phone and data were electronically stored, using the Brazilian version of the SF36 to assess women’s self-perception of quality of life. To analyze a possible relationship between SMM and perceived impairment in quality of life, χ2 and Fisher’s Exact tests were used. Multiple analysis using Generalized Linear Models was applied to identify factors independently associated with the general health score. The main outcome measures were general and domain-specific SF36 scores on quality of life. Results. Maternal morbidity conditions were associated with lower scores of patient perceptions of quality of life in the following domains: physical functioning, role-limiting physical, pain, and general health status. A lower level of school education, not having a partner, caesarean section, and history of previous clinical conditions were associated with a worse perception of general health and quality of life. Conclusion. Health professionals should know the association between life conditions, previous chronic health conditions, and SMM for women during prenatal care to beyond 42 weeks postpartum. Longitudinal and interdisciplinary actions should be put into practice to provide healthcare for these women, with special emphasis on the effective reduction in health inequities.
