Unplanned out-of-hospital birth and risk factors of adverse perinatal outcome: findings from a prospective cohort.

ABSTRACT: BACKGROUND:In France, while most babies are delivered at hospital, emergency medical services (EMS) weekly manage calls for unplanned out-of-hospital births. The objective of our study was to describe neonatal morbidity and mortality, defined as death or neonatal intensive care unit hospitalization at Day 7, in a prospective multicentric cohort of unplanned out-of-hospital births. METHODS:We prospectively analyzed out-of-hospital births from 25 prehospital EMS units in France. The primary outcome was neonatal morbidity and mortality, and the secondary outcome was risk factors associated with neonatal morbidity and mortality. A univariate logistic regression was first made, followed by a multivariate logistic regression with backward selection. RESULTS:From October 2011 to August 2018, a total of 1670 unplanned out-of-hospital births were included. Of these, 1652 (99.2%) were singleton and 1537 (93.5%) had prenatal care. Maternal mean age of the study population was 30?±?5.5 (range 15 to 48). The majority of women were multiparous, but 13% were nulliparous. Overall, 45.3% of these unplanned out-of-hospital births were medically-driven, either by phone during medical regulation (12.5%) or on scene by the prehospital emergency medical service units (32.9%). The prevalence of neonatal morbidity and mortality was 6.3% (n =?106) after an unplanned out-of-hospital birth (death before Day 7: n =?20; 1.2%). The multivariate logistic regression found that multiparity (adjusted Odds Ratio?=?70.7 [4.7-1062]), prematurity (adjusted Odds Ratio?=?6.7 [2.1-21.4]), maternal pathology (adjusted Odds Ratio?=?2.8 [1.0-7.5]) and hypothermia (adjusted Odds Ratio?=?2.8 [1.1-7.6]) were independent predictive factors of neonatal morbidity and mortality. CONCLUSIONS:Our study assessed for the first time risk factors for adverse perinatal outcome in a large and multicenter cohort of unplanned out-of-hospital births. We have to improve temperature management in the out-of-hospital field and future trials are required to investigate strategies to optimize newborns management in the prehospital area.

Project description:ObjectivesThe aim of this study was to determine predictors of adverse perinatal outcome among women who gave birth at Medical Center of Southwest Ethiopia.SettingInstitutional based retrospective cohort study was conducted among women who gave birth at Medical Center of Southwest Ethiopia.ParticipantsMedical record of 777 women was included in the study by using maternity HMIS logbook as entry point. Simple random sampling technique without replacement was employed to select individual medical record using computer generated random numbers.Primary outcome measuredPredictors of adverse perinatal outcome were examined using modified Poisson regression with a robust SE.ResultsMajority, 74.1% of the participants were in the age group of 21-34 years and the median age was 26 (IQR=7) years. More than one-third, 35.9% of the mothers were primigravida and only 21.2% of them had above four antenatal cares (ANC) visit. The overall incidence of adverse perinatal outcome was 31.5% (95% CI: 28.3 to 34.9). Maternal age less than 20 years (adjusted risk ratio, aRR=1.3; 95% CI: 1.01 to 1.5), rural residence (aRR=1.27; 95% CI: 1.04 to 1.59), presence of antepartum haemorrhage in current pregnancy (aRR=1.7; 95% CI: 1.38 to 2.07), maternal anaemia (aRR=1.25; 95% CI: 1.03 to 1.53), lack of ANC visit (aRR=2.29; 95% CI: 1.35 to 3.90), induced labour (aRR=1.77; 95% CI: 1.43 to 2.19) and being positive for venereal disease research laboratory (VDRL) test in current pregnancy (aRR=2.0; 95% CI: 1.16 to 3.38) were found to be significantly associated with adverse perinatal outcome.ConclusionThe incidence of adverse perinatal outcome in the study area is high and maternal age less than 20, rural residency, maternal anaemia, antepartum haemorrhage in the current pregnancy, inadequate ANC visit, induction of labour and being positive for VDRL test were found to predict occurrence of adverse perinatal outcome. Majority of these problems can be managed by providing quality antenatal, intrapartum and post-natal care.

Project description:BackgroundThe impact of coronavirus disease 2019 (COVID-19) on adverse perinatal outcomes remains unclear.ObjectiveThis study aimed to investigate whether COVID-19 is associated with adverse perinatal outcomes in a large national dataset and to examine the rates of adverse outcomes during the pandemic compared with the rates of adverse outcomes during the prepandemic period.Study designThis observational cohort study included 683,905 patients, between the ages of 12 and 50, hospitalized for childbirth and abortion between January 1, 2019, and May 31, 2021. During the prepandemic period, 271,444 women were hospitalized for childbirth. During the pandemic, 308,532 women were hospitalized for childbirth, and 2708 women had COVID-19. The associations between COVID-19 and inhospital adverse perinatal outcomes were examined using propensity score-adjusted logistic regression.ResultsWomen with COVID-19 were more likely to experience both early and late preterm birth (adjusted odds ratios, 1.38 [95% confidence interval, 1.1-1.7] and 1.62 [95% confidence interval, 1.3-1.7], respectively), preeclampsia (adjusted odds ratio, 1.2 [95% confidence interval, 1.0-1.4]), disseminated intravascular coagulopathy (adjusted odds ratio, 1.57 [95% confidence interval, 1.1-2.2]), pulmonary edema (adjusted odds ratio, 2.7 [95% confidence interval, 1.1-6.3]), and need for mechanical ventilation (adjusted odds ratio, 8.1 [95% confidence interval, 3.8-17.3]) than women without COVID-19. There was no significant difference in the prevalence of stillbirth among women with COVID-19 (16/2708) and women without COVID-19 (174/39,562) (P=.257). There was no difference in adverse outcomes among women who delivered during the pandemic vs prepandemic period. Combined inhospital mortality was significantly higher for women with COVID-19 (147 [95% confidence interval, 3.0-292.0] vs 2.5 [95% confidence interval, 0.0-7.5] deaths per 100,000 women). Women diagnosed with COVID-19 within 30 days before hospitalization were more likely to experience early preterm birth, placental abruption, and mechanical ventilation than women diagnosed with COVID-19 >30 days before hospitalization for childbirth (4.0% vs 2.4% for early preterm birth [adjusted odds ratio, 1.7; 95% confidence interval, 1.1-2.7]; 2.2% vs 1.2% for placental abruption [adjusted odds ratio, 1.86; 95% confidence interval, 1.0-3.4]; and 0.9% vs 0.1% for mechanical ventilation [adjusted odds ratio, 13.7; 95% confidence interval, 1.8-107.2]).ConclusionWomen with COVID-19 had a higher prevalence of adverse perinatal outcomes and increased in-hospital mortality, with the highest risk occurring when the diagnosis was within 30 days of hospitalization, raising the possibility of a high-risk period.

Project description:BackgroundThe BNT162b2 mRNA (Pfizer-BioNTech) and ChAdOx1 nCoV-19 (Oxford-AstraZeneca) COVID-19 vaccines have shown high efficacy against disease in phase 3 clinical trials and are now being used in national vaccination programmes in the UK and several other countries. Studying the real-world effects of these vaccines is an urgent requirement. The aim of our study was to investigate the association between the mass roll-out of the first doses of these COVID-19 vaccines and hospital admissions for COVID-19.MethodsWe did a prospective cohort study using the Early Pandemic Evaluation and Enhanced Surveillance of COVID-19-EAVE II-database comprising linked vaccination, primary care, real-time reverse transcription-PCR testing, and hospital admission patient records for 5·4 million people in Scotland (about 99% of the population) registered at 940 general practices. Individuals who had previously tested positive were excluded from the analysis. A time-dependent Cox model and Poisson regression models with inverse propensity weights were fitted to estimate effectiveness against COVID-19 hospital admission (defined as 1-adjusted rate ratio) following the first dose of vaccine.FindingsBetween Dec 8, 2020, and Feb 22, 2021, a total of 1 331 993 people were vaccinated over the study period. The mean age of those vaccinated was 65·0 years (SD 16·2). The first dose of the BNT162b2 mRNA vaccine was associated with a vaccine effect of 91% (95% CI 85-94) for reduced COVID-19 hospital admission at 28-34 days post-vaccination. Vaccine effect at the same time interval for the ChAdOx1 vaccine was 88% (95% CI 75-94). Results of combined vaccine effects against hospital admission due to COVID-19 were similar when restricting the analysis to those aged 80 years and older (83%, 95% CI 72-89 at 28-34 days post-vaccination).InterpretationMass roll-out of the first doses of the BNT162b2 mRNA and ChAdOx1 vaccines was associated with substantial reductions in the risk of hospital admission due to COVID-19 in Scotland. There remains the possibility that some of the observed effects might have been due to residual confounding.FundingUK Research and Innovation (Medical Research Council), Research and Innovation Industrial Strategy Challenge Fund, Health Data Research UK.

Project description:Universal health coverage (UHC) aims to improve child health through preventive primary care and vaccine coverage. Yet, in many developed countries with UHC, unplanned and ambulatory care sensitive (ACS) hospital admissions in childhood continue to rise. We investigated the relation between preventive primary care and risk of unplanned and ACS admission in children in a high-income country with UHC.We followed 319,780 children registered from birth with 363 English practices in Clinical Practice Research Datalink linked to Hospital Episodes Statistics, born between January 2000 and March 2013. We used Cox regression estimating adjusted hazard ratios (HR) to examine subsequent risk of unplanned and ACS hospital admissions in children who received preventive primary care (development checks and vaccinations), compared with those who did not.Overall, 98% of children had complete vaccinations and 87% had development checks. Unplanned admission rates were 259, 105 and 42 per 1000 child-years in infants (aged <?1 year), preschool (1-4 years) and primary school (5-9 years) children, respectively. Lack of preventive care was associated with more unplanned admissions. Infants with incomplete vaccination had increased risk for all unplanned admissions (HR 1.89, 1.79-2.00) and vaccine-preventable admissions (HR 4.41, 2.59-7.49). Infants lacking development checks had higher risk for unplanned admission (HR 4.63, 4.55-4.71). These associations persisted across childhood. Children who had higher consulting rates with primary care providers also had higher risk of unplanned admission (preschool children: HR 1.17, 1.17-1.17). One third of all unplanned admissions (62,154/183,530) were for ACS infectious illness. Children with chronic ACS conditions, asthma, diabetes or epilepsy had increased risk of unplanned admission (HR 1.90, 1.77-2.04, HR 11.43, 8.48-15.39, and HR 4.82, 3.93-5.91, respectively). These associations were modified in children who consulted more in primary care.A high uptake of preventive primary care from birth is associated with fewer unplanned and ACS admissions in children. However, the clustering of poor health, a lack of preventive care uptake, and social deprivation puts some children with comorbid conditions at very high risk of admission. Strengthening immunisation coverage and preventive primary care in countries with poor UHC could potentially significantly reduce the health burden from hospital admission in children.
