Term perinatal mortality audit in the Netherlands 2010-2012: a population-based cohort study.

ABSTRACT:

Objective

To assess the implementation and first results of a term perinatal internal audit by a standardised method.

Design

Population-based cohort study.

Setting

All 90 Dutch hospitals with obstetric/paediatric departments linked to community practices of midwives, general practitioners in their attachment areas, organised in perinatal cooperation groups (PCG).

Population

The population consisted of 943 registered term perinatal deaths occurring in 2010-2012 with detailed information, including 707 cases with completed audit results.

Main outcome measures

Participation in the audit, perinatal death classification, identification of substandard factors (SSF), SSF in relation to death, conclusive recommendations for quality improvement in perinatal care and antepartum risk selection at the start of labour.

Results

After the introduction of the perinatal audit in 2010, all PCGs participated. They organised 645 audit sessions, with an average of 31 healthcare professionals per session. Of all 1102 term perinatal deaths (2.3/1000) data were registered for 86% (943) and standardised anonymised audit results for 64% (707). In 53% of the cases at least one SSF was identified. Non-compliance to guidelines (35%) and deviation from usual professional care (41%) were the most frequent SSF. There was a (very) probable relation between the SSF and perinatal death for 8% of all cases. This declined over the years: from 10% (n=23) in 2010 to 5% (n=10) in 2012 (p=0.060). Simultaneously term perinatal mortality decreased from 2.3 to 2.0/1000 births (p<0.00001). Possibilities for improvement were identified in the organisation of care (35%), guidelines or usual care (19%) and in documentation (15%). More pregnancies were antepartum selected as high risk, 70% in 2010 and 84% in 2012 (p=0.0001).

Conclusions

The perinatal audit is implemented nationwide in all obstetrical units in the Netherlands in a short time period. It is possible that the audit contributed to the decrease in term perinatal mortality.

Project description:BackgroundSomali women deliver at greater gestational age with limited information on the associated perinatal mortality. Our objective is to compare perinatal mortality among Somali women with the population rates.MethodsThis is a retrospective cohort study from all births that occurred in Minnesota between 2011 and 2017. Information was obtained from certificates of birth, and neonatal and fetal death. Data was abstracted from 470,550 non-anomalous births ≥37 and ≤ 42 weeks of gestation. The study population included U.S. born White, U.S. born Black, women born in Somalia or self-identified as Somali, and women who identified as Hispanic regardless of place of birth (377,426). We excluded births < 37 weeks and > 42 weeks, > 1 fetus, age < 18 or > 45 years, or women of other ethnicities. The exposure was documented ethnicity or place of birth, and the outcomes were live birth, fetal death, neonatal death prior to 28 days, and perinatal mortality rates. These were calculated using binomial proportions with 95% confidence intervals and compared using odds ratios adjusted (aOR) for diabetes, hypertension and maternal body mass index.ResultsThe aOR [95%CI] for stillbirth rate in the Somali cohort was greater than for U.S. born White (2.05 [1.49-2.83]) and Hispanic women (1.90 [1.30-2.79]), but similar to U.S. born Black women (0.88 [0.57-1.34]). Neonatal death rates were greater than for U.S. born White (1.84 [1.36-2.48], U.S. born Black women (1.47 [1.04-2.06]) and Hispanic women (1.47 [1.05-2.06]). This did not change after analysis was restricted to those with spontaneous onset of labor. When analyzed by week, at 42 weeks Somali aOR for neonatal death was the same as for U.S. born White women, but compared against U.S. born Black and Hispanic women, was significantly lower.ConclusionsThe later mean gestational age at delivery among women of Somali ethnicity is associated with greater overall risk for stillbirth and neonatal death rates at term, except compared against U.S. born Black women with whom stillbirth rates were not different. At 42 weeks, Somali neonatal mortality decreased and was comparable to that of the U.S. born White population and was lower than that of the other minorities.

Project description:PurposeObservational population-based research is a very suitable non-invasive method for studies in the vulnerable populations of pregnant women and children. Therefore, the PHARMO Perinatal Research Network (PPRN) was set up as a resource for life course perinatal and paediatric research by linking population-based data from existing registrations.ParticipantsFrom 1999 to 2017, the PPRN captures approximately 542 900 pregnancies of 387 100 mothers ('Pregnancy Cohort'). Additionally, mother-child linkage is currently available for a quarter of these pregnancies ('Child Cohort'). The PPRN contains preconceptional information on maternal healthcare, as well as detailed pregnancy and neonatal data, extending into long-term follow-up and outcomes after birth for both mother and child up to nearly 20 years. It includes linked data from different primary and secondary healthcare settings.Findings to dateThrough record linkage of the Netherlands Perinatal Registry and the PHARMO Database Network, we have established a large population-based research network including data on demographics, medication use, medical conditions and details concerning labour, birth and neonatal outcomes. Here, we provide an overview of record types available from the PPRN, available database follow-up and pregnancy characteristics of the PPRN cohorts. The PPRN has been used for a number of different pharmacoepidemiological studies, for example, to confirm that preterm-born infants were more likely than full-term infants to be hospitalised or use medication. Similar long-term comparisons showed that children born following spontaneous preterm labour were at increased risk of neurodevelopmental and respiratory conditions. Most recently, the PPRN provided important evidence on the trends in use of potentially harmful medication during pregnancy.Future plansThe PPRN provides a unique and rich data set facilitating large-scale observational pharmacoepidemiological perinatal research. The patient-level linkage of many different healthcare data sources allows for long-term follow-up of mother and child, with ongoing annual updates.

Project description:OBJECTIVES:To study the effect of an urban perinatal health programme in Rotterdam, the Netherlands, on perinatal outcomes. DESIGN:A retrospective cohort study with difference-in-differences analysis using individual-level perinatal outcome data from the Dutch Perinatal Registry 2003-2014 linked to Central Bureau of Statistics data of migration background and individual disposable household income. INTERVENTION:The programme consisted of perinatal health promotion, risk selection and risk-guided pregnancy care, and a new primary care child birth centre. The programme was implemented during 2009-2012. PRIMARY OUTCOME MEASURES:We compared trends in perinatal mortality, preterm delivery and small-for-gestational-age births between targeted urban neighbourhoods in Rotterdam (n=61 415) and all other urban neighbourhoods in the Netherlands (n=881 202). The effect of the programme was modelled as a change in trend of each perinatal outcome in the treatment group post intervention compared with the control population from January 2010 onwards. All analyses were adjusted for maternal age, parity, ethnicity and individual-level low socioeconomic status (SES). We also conducted a stratified analysis by SES. RESULTS:During 2003-2014, downward trends in perinatal mortality (adjusted OR (aOR) 0.9439 per year, 95% CI 0.9362 to 0.9517), preterm birth (aOR 0.9970 per year, 95% CI 0.9944 to 0.9997) and small-for-gestational-age births (aOR 0.9809 per year, 95% CI 0.9787 to 0.9831) in the entire study population were observed. No demonstrable changes in these trends were found in the intervention group after the programme had started. The stratified analyses by SES showed no changes in trends post intervention in both strata either. CONCLUSIONS:The programme had no demonstrable effects on perinatal outcomes. The intervention may not have reached a sufficient proportion of the population or has provided too little contrast to the widespread attention for inequalities in pregnancy outcomes occurring simultaneously in the Netherlands.

Project description:BackgroundIt is unclear whether an upper gastrointestinal bleed is an isolated gastrointestinal event or an indicator of a deterioration in a patient's overall health status. Therefore, we investigated the excess causes of death in individuals after a non-variceal bleed compared with deaths in a matched sample of the general population.Methods and findingsLinked longitudinal data from the English Hospital Episodes Statistics (HES) data, General Practice Research Database (GPRD), and Office of National Statistics death register were used to define a cohort of non-variceal bleeds between 1997 and 2010. Controls were matched at the start of the study by age, sex, practice, and year. The excess risk of each cause of death in the 5 years subsequent to a bleed was then calculated whilst adjusting for competing risks using cumulative incidence functions. 16,355 patients with a non-variceal upper gastrointestinal bleed were matched to 81,523 controls. The total 5-year risk of death due to gastrointestinal causes (malignant or non-malignant) ranged from 3.6% (≤ 50 years, 95% CI 3.0%-4.3%) to 15.2% (≥ 80 years, 14.2%-16.3%), representing an excess over controls of between 3.6% (3.0%-4.2%) and 13.4% (12.4%-14.5%), respectively. In contrast the total 5-year risk of death due to non-gastrointestinal causes ranged from 4.1% (≤ 50 years, 3.4%-4.8%) to 46.6% (≥ 80 years, 45.2%-48.1%), representing an excess over controls of between 3.8% (3.1%-4.5%) and 19.0% (17.5%-20.6%), respectively. The main limitation of this study was potential misclassification of the exposure and outcome; however, we sought to minimise this by using information derived across multiple linked datasets.ConclusionsDeaths from all causes were increased following an upper gastrointestinal bleed compared to matched controls, and over half the excess risk of death was due to seemingly unrelated co-morbidity. A non-variceal bleed may therefore warrant a careful assessment of co-morbid illness seemingly unrelated to the bleed.

Project description:BackgroundTestis cancer (TC) patients are young with excellent cancer prognosis. Hence, the risk of late-onset treatment-related morbidity and mortality is of concern due to longer survival after treatment.ObjectiveWe set to characterize long-term survival of TC patients through a Canadian population dataset.Design setting and participantsWe used a population-based dataset, the Canadian Census Health and Environment Cohort (CanCHEC), to identify individuals diagnosed with TC between 1991 and 2010. We compared them with all other male individuals without TC.Outcome measurements and statistical analysisThe primary outcome was mortality due to cardiovascular disease (CVD) or nontesticular malignancy. Mann-Whitney or chi-square test was used where applicable. Data were analyzed using a Cox proportional hazard model with and without matching.Results and limitationsWe identified 1950 individuals with TC. We compared them with 1 300 295 men with no TC. There were 335 deaths in the study group during the study period (17.2%) with a mean follow-up of 19.6 yr. TC patients were at increased risk of death from secondary malignancies (hazard ratio [HR] 1.63, 95% confidence interval [CI] 1.39-1.91; p < 0.0001) with specific risks for hematologic neoplasms (HR 3.86, 95% CI 2.78-5.37; p < 0.001) and other malignancies (HR 2.41, 95% CI 1.76-3.29; p < 0.001). Gastrointestinal, hematologic, and respiratory toxicities were the most common secondary malignancies leading to death. When stratified according to histology, nonseminoma (NS) patients were at significantly increased risk of death from CVD (HR 2.03, 95% CI 1.27-3.25; p = 0.0032). Individuals with seminoma were at increased risk of death from other nontestis neoplasms (HR 1.46, 95% CI 1.17-1.82; p = 0.0007), specifically hematologic neoplasms (HR 2.09, 95% CI 1.18-3.72; p = 0.0118).ConclusionsNS patients are at increased risk of CVD-related death, whereas seminoma patients are at increased risk of death from non-testis-related malignancies.Patient summaryWe report long-term mortality following diagnosis of testis cancer. Nonseminoma patients have an increased risk of death from cardiovascular disease, while seminoma patients have an increased risk of death from secondary malignancies.
