The International Network of Obstetric Survey System.

OBJECTIVE: To informed about international surveillance network severe maternal morbidity and mortality - INOSS. DESIGN: Literature review. SETTINGS: 1st Department of Gynaecology and Obstetrics Faculty of Medicine, Comenius University and University Hospital, Bratislava, Slovak Republic. METHODS: Literate review of articles published till august 2019. RESULTS: The International Network of Obstetric Survey Systems (INOSS) is an international network that connects countries with the same or similar system of surveillance of acute severe maternal morbidity and mortality. The INOSS was established in year 2010 by twelve countries. Nowadays 19 countries are involved in the INOSS. The cooperation between member countries is focused on the acquisition of relevant data about rare severe acute maternal morbidities. INOSS in 2017 year unified definitions of 8 severe acute maternal morbidities according Delphi method: eclampsia, amniotic fluid embolism, peripartum hysterectomy, severe primary postpartum haemorrhage, uterine rupture, abnormally invasive placenta, spontaneous hemoperitoneum in pregnancy, and cardiac arrest in pregnancy. CONCLUSION: The international cooperation allows the acquisition of relevant epidemiologic data and the optimalization of the treatment according the evidence-based medicine.

Analyses of severe acute maternal morbidity in Slovakia during years 2012-2016.

AIM: Severe acute maternal morbidity (SAMM) is a state of the woman, when she nearly died, but survived. The aim of study was to find out the exact incidence of SAMM in Slovakia, establishment of functional surveillance system and improve quality of health care. MATERIALS AND METHODS: The regular annual analyses of SAMM cases in Slovakia from January 1st 2012 to December 31st 2016. Observed SAMM included: peripartum haemorrhage, peripartum hysterectomy, uterine rupture, abnormally invasive placenta, HELLP syndrome, eclampsia, sepsis, transport to intensive care unit or anaesthesiology and non-fatal amniotic fluid embolism. RESULTS: The response rate of questionnaires was 84.8 %. The overall confirmed incidence of SAMM was 6.35/1,000 births (95% CI 6.03-6.67). The most often causes of SAMM were: peripartum haemorrhage (2.1/1,000 births), transport to intensive care unit or anaesthesiology (1.46/1,000 births), peripartum hysterectomy (0.84/1,000 births) and HELLP syndrome (0.63/1,000 births). The average age of women with SAMM was 30.3 years (14-46) and average parity was 1.16 (0-15). CONCLUSION: The incidence of SAMM and especially incidence of peripartum haemorrhage and peripartum hysterectomy in Slovakia is one of the highest in Europe. To decrease incidence and improve management and outcome of patients, regular audit of SAMM is needed (Tab. 3, Fig. 2, Ref. 30).

Maternal morbidity and mortality in Slovak Republic in the years 2007-2015.

OBJECTIVE: Analysis of maternal morbidity and mortality in Slovak Republic in the years 2007-2015. DESIGN: Prospective epidemiological perinatological nation-wide. SETTINGS: 1st Department of Gynaecology and Obstetrics Faculty of Medicine, Comenius University and University Hospital, Bratislava, Slovak Republic. METHODS: The analysis of selected maternal morbidity and mortality data prospective collected in the years 2007-2015. RESULTS: Cesarean section rate progressively increased from 24.1% in the year 2007 up to 30.8% in the year 2013 and up to year 2015 decreased to 30.2%. Vacuum-extraction frequency was 1.3% in the year 2007 and to the year 2015 increased up to 1.6%. Forceps frequency was the same in the year 2007 and 2015: 0.6%. In the years 2008-2015 frequency of perineal tears 3th and 4th degree increased from 0.44% to 0.68% and frequency of episiotomies decreased from 74.7% to 57.2%. In the years 2012-2015 incidence of total severe acute maternal morbidity per 1,000 births was 5.85, peripartum hysterectomy 0.78, severe postpartum bleeding 2.03, transport to anaesthesiology department/intensive care unit 1.26, eclampsia 0.2, HELLP syndrome 0.6, abnormal placental invasion 0.38, uterine rupture 0.45, severe sepsis in pregnancy and puerperium 0.14 and frequency of nonfatal amniotic fluid embolism was 2/100,000 maternities. Total maternal mortality ratio in this period was 11.5 and pregnancy-related deaths ratio 9.9 per 100,000 live births. CONCLUSION: The highest cesarean section rate in Slovakia, 30.8 %, was in the year 2013, but in the next years slowly decreased. Frequency of episiotomies decreased in followed period too. Incidence of severe acute maternal morbidity was 5.85 per 1,000 births. Maternal mortality ratio in Slovakia was one of the highest in European Union and not corresponding with good level of perinatal mortality. Improving of cesarean section rate and episiotomy, incidence of severe acute maternal morbidity and maternal mortality still need to be improved in Slovak Republic.

Active surveillance of incidence and risk factors of hemolysis, elevated liver enzymes and low platelets syndrome in Slovakia.

OBJECTIVE: Hemolysis, Elevated Liver Enzymes, Low Platelets syndrome (HELLP syndrome) is one of the actively haunted maternal morbidity through Slovak Obstetric Survey System (SOSS), the organisation for surveillance of severe maternal morbidity and mortality in Slovakia. METHODS: The questionaires were sent in 55 Obstetric Units in Slovakia. The analyzed and here presented data had been collected cases those happened in the period from 1.1.2012 till 31.12.2014. Controls were women from SR during observed years, who delivered without HELLP syndrome. RESULTS: The return rate of questionnaires was 89.67 %, thus covering 146 972 deliveries during the study period in Slovakia. The exact incidence of HELLP syndrome was 0.63/1000 deliveries (CI 95 % 0.51-0.78). Risk factors were age > 30 (OR = 1.63), nuliparous (OR = 2.96), pregnancy after assisted reproduction technology (OR = 8.29) and multiple pregnancy OR = 9.19). The mean gestation age at delivery was 33.8th weeks. Vaginal delivery was by 10 (10.8 %) patients with HELLP syndrome and in the 83 (89.2 %) patients pregnancy was terminated with acute caesarean section. There were reported 45 050 cases (30.7 %) of the caesarean section in the control group throughout the study period. CONCLUSION: The older age, nulliparity, multiple pregnancy and pregnancy after assisted reproduction techniques was identified as a significant risk factors of HELLP syndrome (Tab. 5, Fig. 1, Ref. 21).

Perinatal mortality and morbidity in Slovak Republic in the years 2007-2015.

OBJECTIVE: Comparison of perinatal mortality in Slovak Republic in three periods during the years 2007-2015. DESIGN: Epidemiological perinatal nation-wide. SETTINGS: 1st Department of Gynaecology and Obstetrics Faculty of Medicine, Comenius University and University Hospital, Bratislava, Slovak Republic. METHODS: The analysis of prospectively collected selected perinatal data in the years 2007-2015. RESULTS: In the year 2007 there were 63 obstetrics units, 51,146 deliveries and that of live births 51,650 in Slovak Republic. The number of obstetrics units decreased to 54 in the years 2015, but total number of deliveries increased to 55,139 and that of live births increased to 55,643. Preterm deliveries rate increased from 7.3% in the year 2007 to 8.5% in the year 2010 and decreased to 7.5% in the year 2015. Perinatal mortality rate decreased from 6.2 in the year 2007 to 4.8 in the year 2013, and increased again in the years 2014 and 2015 to 5.3 and 5.6 per 1,000 still- and live-births respectively. During the years 2007-2015 stillbirth participate at perinatal mortality with 64%, low birth weight with 64% and severe congenital anomalies with 20%. Transport in utero to perinatological centres in the years 2007-2015 has increased from 57% to 66% for infants 1000-1499 g and from 75% to 79% for infants below 1000 g. CONCLUSION: In the year 2013 perinatology in Slovak Republic reached the best result in perinatal mortality rate 4.8 (0.48%), but in next two years has increased over 5. Prenatal detection of severe congenital abnormalities, transport in utero very low birth weight infants, centralisation of high-risk pregnancies and obstetric and neonatal intensive care units equipment need still to be improved in Slovak Republic. Keywords perinatal mortality, preterm delivery, multiple pregnancy, neonatal intensive care unit, low birth weight, very low birth weight.

OBJECTIVE: Analysis of maternal morbidity and mortality in Slovak Republic (SR) in the years 2007-2012. DESIGN: Epidemiological perinatological nation-wide. SETTINGS: 1st Department of Gynaecology and Obstetrics School of Medicine, Comenius University and University Hospital, Bratislava, Slovak Republic. METHODS: The analysis of selected maternal morbidity and mortality data prospective collected in the years 2007-2012 from all obstetrics hospitals in the Slovak Republic. RESULTS: Caesarean section rate progressively increased from 24.1% in the year 2007 up to 30.3% in the year 2012. In the year 2012 the frequency of vacuum-extraction was 1.4%, forceps 0.6%, perineal tears 3th and 4th degree 0.49% and episiotomy 65%. Incidence of total severe acute maternal morbidity was 6.34 per 1,000 births. Incidence (per 1,000 births) of transport to anaesthesiology department/intensive care unit was 2.32, postpartum hysterectomy 0.72, HELLP syndrome 0.63, eclampsia 0.29, abnormal placental invasion 0.37, uterine rupture 0.27, severe sepsis in pregnancy and puerperium 0.21. In the years 2007-2012 frequency of fatal amniotic fluid embolism was 2.46/100,000 maternities or 2.43/100,000 live-births. Maternal mortality ratio in this period was 14 per 100,000 live births and pregnancy-related deaths ratio was 11.9 per 100,000 live births. CONCLUSION: In the year 2012 Slovakia reached the highest caesarean section rate in her own history - 30.3%. Incidence of severe acute maternal morbidity was 6.34 per 1,000 births. Maternal mortality ratio in Slovakia was one of the highest in European Union. Decreasing of caesarean section rate and episiotomy, incidence of severe acute maternal morbidity and maternal mortality still need to be improved in Slovak Republic.

Pregnancy and neonatal outcomes in women with type 1 diabetes mellitus.

AIM: The aim of study was to compare some perinatal outcomes in mothers with type 1 diabetes mellitus (T1DM). MATERIAL AND METHODS: All patients with T1DM delivered at the 1st Department of Obstetrics and Gynaecology of Faculty of Medicine, Comenius University in Bratislava from January 1st 2009 to December 31th 2015 were included to the study. RESULTS: Out of 118 diabetic mothers, 46.6 % had vasculopathy and 53. 4 % were without microvascular complications. In the vasculopathy group, significantly higher incidence rates of preeclampsia (49. 1 versus 19.1 %; p = 0.002) and caesarean section (89.1 versus 68.3 %; p = 0.017) were found. Neonatal morbidity and mortality rates were higher in vasculopathy group (but not statistically significantly). Preparation for pregnancy improves perinatal and neonatal results. Nevertheless, this preparation in our study group was received only in 9.3 %. Perinatal mortality was 25.4 per 1,000 total births. CONCLUSION: For pregnancy of diabetic women to become possible a qualified management must be provided. Good outcomes for both women and newborns are real when preparation for pregnancy and metabolic control before and during whole pregnancy are at adequate level (Tab. 3, Ref. 28).

OBJECTIVE: Comparison of perinatal mortality in Slovak Republic in the years 2007-2009 and in the years 2010-2012. DESIGN: Epidemiological perinatal nation-wide. SETTING: 1st Department of Gynaecology and Obstetrics School of Medicine, Comenius University and University Hospital, Bratislava, Slovak Republic. METHODS: The analysis of selected perinatal data prospectively collected in the years 2007-2009 and in the years 2010-2012. RESULTS: In the year 2007 there were 63 maternity hospitals, 51,146 deliveries and that of live births 51,650 in Slovak Republic. In the years 2010-2012 decreased the number of maternity hospitals, total number of deliveries and that of live births from 57 to 55, from 55,362 to 54,996 and from 55,901 to 55,643 respectively. Preterm deliveries rate increased from 7.4 to 7.7% and multiple pregnancies rate from 1.4% to 1.5% in the years 2010-2012 compared to years 2007-2009. Perinatal mortality rate decreased from 6.2 in the year 2007 to 5.1 per 1,000 still and live births in the year 2012. During the years 2007-2012 stillbirth participate in perinatal mortality 64%, low birth weight 65% and severe congenital anomalies 19%. Transport in utero to perinatal centres decreased in the years 2007-2012. It was from 64% to 56% for infants with very low birth weight and from 75% to 70% for infants with extremely low birth weight. CONCLUSION: In the year 2012 Slovak perinatology reach the best result in perinatal mortality rate 5.1 (0.51%). Centralisation of high-risk pregnancies, transport in utero very low birth weight infants, prenatal detection of severe congenital abnormalities and obstetric and neonatal intensive care units equipment need still to be improved in Slovak Republic.
