Risk factors for poor neonatal outcome in pregnancies with decreased fetal movements

Is it possible to monitor fetal movements with a wearable device? A review of novel technologies

Stillbirth is often preceded by reduced fetal movements and obstetric intervention is necessitated for stillbirth prevention. Yet, despite fetal movements being one of the few tangible ways a pregnant woman and the clinical team can assess the wellbeing of her baby, there are few validated, objective means for pregnant women to quantify the frequency and nature of an unborn baby's movements. Traditional methods of assessing fetal wellbeing such as cardiotocography and fetal movement charts have a lack of diagnostic accuracy, and often lead to false positive intervention. The need for fetal movement counting has led to the development of objective methods to attempt to quantify movements. Some are based on electrocardiography, others on the principles of accelerometery, phonography and optical fibre technology. This review paper not only explores these technologies and evaluates the state-of the-art fetal movement monitoring, but explains the engineering principles underpinning the various technologies, and explores the importance and practice of fetal movement monitoring. To this end, we conclude that there is still a need for the continued development of innovations which will enable a pregnant woman to carry out everyday activities, whilst confident in the knowledge that her unborn child's wellbeing is being accurately monitored, and that feedback from the monitoring device is readily accessible to her.

Reduced fetal movements and COVID-19 infection: a retrospective cohort study

BACKGROUND

Fetal movements are an important indicator of fetal well-being; therefore, reduced fetal movements (RFMs) can indicate fetal compromise. RFM is associated with fetal growth restriction (FGR) and intrauterine fetal death (IUFD). Studies have implied that COVID-19 infection increases the risk of adverse fetal outcomes, such as preterm birth and IUFD. It is unclear how COVID-19 infection may aggravate these fetal outcomes among women presenting with RFM. The aims of the study were to (1) determine whether adverse fetal outcomes in women with RFM increased in 2020 compared to 2019, the year before the pandemic, and (2) evaluate whether maternal COVID-19 infection during pregnancy was a risk factor for adverse fetal outcomes in comparison to previously established risk factors among women seeking care for RFM.

METHODS

All women who sought care due to RFM and were delivered at Soder Hospital from 2019 to 2020 were included. Fetal composite outcomes were constructed and compared between women with RFM and COVID-19 and women with RFM but without COVID-19.

RESULTS

COVID-19 infection did not increase the risk of adverse fetal outcomes in women who sought care for RFM. A twofold risk for adverse fetal outcomes was found among all primiparous women vs. multiparous women with RFM (98/788 [12.4%] vs 37/644 [9.8%], AOR = 2.5, 95% CI (1.6-3.7).

CONCLUSION

The proportion of adverse composite outcomes among women with RFM during the first year of the pandemic did not increase compared to the year before. Composite outcomes were marginally higher in the COVID-19-positive group compared to the COVID-19-negative group, but it was not statistically significant.

Pregnancy outcomes in correlation with placental histopathology in pregnancies complicated by fetal growth restriction with vs. without reduced fetal movements

PURPOSE

Fetal movements are crucial indicators of fetal well-being, with reduced fetal movements (RFM) suggesting potential fetal compromise. Fetal growth restriction (FGR), often linked to placental insufficiency, is a major cause of perinatal morbidity and mortality. This study aimed to investigate the neonatal, labor, and placental outcomes of FGR pregnancies with and without RFM at term.

METHODS

In this retrospective study, data from all term, singleton deliveries with FGR and concomitant RFM were obtained and compared to an equal control group of FGR without RFM. Maternal characteristics, pregnancy and neonatal outcomes, and placental histology were compared. The primary outcome was a composite of adverse neonatal outcomes. A multivariable regression analysis was performed to identify independent associations with adverse neonatal outcomes.

RESULTS

During the study period, 250 FGR neonates with concomitant RFM and an equal control group were identified. The groups did not differ in maternal demographics aside from significantly higher rates of maternal smoking in the RFM group (p < 0.001). Polyhydramnios and oligohydramnios (p = 0.032 and p = 0.007, respectively) and meconium-stained amniotic fluid (p < 0.001) were more prevalent in the FGR+RFM group. Additionally, the RFM group showed higher rates of adverse neonatal outcomes despite having larger neonates (p = 0.047 and p < 0.001, respectively). No significant differences were observed in placental findings. Logistic regression identified RFM as an independent predictor of adverse neonatal outcomes (aOR 2.45, 95% CI 1.27-4.73, p = 0.008).

CONCLUSION

Reduced fetal movements are significant and independent predictors of worse neonatal outcomes in FGR pregnancies, suggesting an additional acute insult on top of underlying placental insufficiency.

Maternal perception of decreased fetal movements is independent of infant size

OBJECTIVE

Fetal movements are often used as a surrogate for fetal wellbeing. Previous research suggests a link between maternal perception of decreased fetal movements (DFM) and small-for-gestational-age (SGA) infants. The aim of this study was to investigate the association between maternal presentation with DFM and birth-weight centile categories at a large Australian perinatal center.

METHODS

This was a retrospective study of non-anomalous singleton infants born at ≥ 28 + 0 weeks' gestation between January 2016 and October 2020 at the Mater Mothers' Hospital in Brisbane, Australia. The primary outcome was the rate of DFM according to birth-weight centile category. Maternal demographic characteristics included age, body mass index, ethnicity, parity, medical conditions and previous stillbirth. The association between DFM and birth-weight centile was evaluated using adjusted multinomial regression models. Robust standard errors were used to account for clustering at the patient level. Wald tests and Akaike's and Bayesian information criteria were used to evaluate models.

RESULTS

Over the 5-year study period, 45 042 women met the inclusion criteria. Of these, 6690 (14.9%) women presented with DFM. Of the DFM cohort, 80.9% (5411/6690) had only one presentation with DFM, and 19.1% (1279/6690) had two or more presentations. The overall stillbirth rate was similar in women with DFM (0.1% (8/6690)) and those without DFM (0.1% (50/38 352)). There was no association between DFM (either single or multiple) and infant birth-weight centile.

CONCLUSIONS

This study suggests that presentation with DFM is not associated with infant size. Clinicians should consider additional risk factors and the overall clinical context when deciding appropriate management. DFM is not necessarily an indication for an immediate or urgent ultrasound scan to assess fetal size. © 2024 The Authors.

Are reduced fetal movements "merely" a maternal perception or truly a reflection of umbilical cord complications? A clinical trial

OBJECTIVE

To characterize obstetric outcomes and the association with umbilical cord (UC) complications among women complaining of reduced fetal movements (RFMs).

METHODS

This retrospective cohort compared women with a perception of RFMs within 2 weeks prior to delivery with women who reported no changes in fetal movements in terms of maternal characteristics and neonatal outcomes. A primary outcome of UC complications at delivery was defined. Multivariable regression analysis was performed to identify independent associations with RFMs and UC complications.

RESULTS

In all, 46 103 women were included, 2591 (5.6%) of whom reported RFMs and 43 512 (94.4%) in the control group. Compared with controls, the RFM group was more likely to be nulliparous (42.6% vs 32.2%, P < 0.001), smokers (6.4% vs 5.4%, P = 0.029), or obese (body mass index >30) (16.4% vs 11.6%, P < 0.001). They were also more likely to have an anterior placenta (56.2% vs 51.8%, P < 0.001) and poly/oligohydramnios (0.7% vs 0.4%, P = 0.015 and 3.6% vs 2.1%, P < 0.001, respectively). Induction of labor was more common in the RFM group (33.9% vs 19.7%, P < 0.001), as well as meconium (16.8% vs 15.0%, P = 0.026) and vacuum extractions (10.1% vs 8.0%, P < 0.001). Higher rates of stillbirth and the severe composite neonatal outcome were observed in the RFM group (1.5% vs 0.2%, P < 0.001 and 0.6% vs 0.3%, P = 0.010, respectively). The RFM group was characterized by higher rates of triple nuchal cord (P = 0.015), UC around body or neck (32.2% vs 29.6%, P = 0.010), and true knot (2.3% vs 1.4%, P = 0.002). Multivariable logistic regression found RFMs to be independently associated with triple nuchal cord and with a true cord knot. A sub-analysis including only cases of stillbirth (n = 127) revealed even higher rates of UC complications: 7% of all stillbirths presented with a true cord knot (20% true knots were found in stillbirths preceded by RFMs vs 6.1% in stillbirth cases without RFMs). Additionally, 33.8% of all stillbirths presented with nuchal cord (40% preceded by RFMs vs 33.3% without RFMs).

CONCLUSIONS

RFMs are associated with increased risk of UC complications observed at delivery, as well as increased risk of stillbirth and neonatal adverse outcomes.

Risk factors for adverse outcomes in twin pregnancies: a narrative review

PURPOSE

Globally, the incidence of twin pregnancies is rising owing to the use of assisted reproductive technologies (ART), emigration and deferment of pregnancy until advanced maternal age (AMA). While twin pregnancies have higher absolute risks of adverse outcomes, including miscarriage, stillbirth, neonatal death and preterm delivery, the impact of specific exposures and risk factors related to these outcomes may differ between twin pregnancies and singleton pregnancies. Regarding modifiable factors, data are sometimes based on evidence extrapolated from singleton or whole obstetric populations. Therefore, targeted evidence is required to provide care tailored to twin pregnancies to prevent adverse outcomes. We aimed to comprehensively review the association between different risk factors and adverse outcomes in twin pregnancies, including data on chorionicity, and to compare these to singletons.

MATERIALS AND METHODS

This review examines the risks associated with chorionicity, AMA, body mass index (BMI), socioeconomic and ethnic inequalities, maternal smoking, use of ART, maternal perception of fetal movement, and maternal comorbidities, including hypertensive disorders of pregnancy (HDP) and gestational diabetes mellitus (GDM). Adverse outcomes reported were preterm birth, admission to the neonatal intensive care unit (NICU), stillbirth and neonatal mortality. As such, fetal mortality and morbidity will be under-represented, as pregnancy loss before 22-24 weeks is omitted.

RESULTS

Monochorionicity increases the risk of stillbirth, NICU admission, and preterm delivery in twin pregnancy. AMA predisposes twin pregnancies to higher risks of mortality, admission to the NICU, and preterm birth than singleton pregnancies do. Conversely, the impact of BMI, socioeconomic inequalities, smoking, ART, and HDP on adverse outcomes appears to be lower in twin pregnancies than in singleton pregnancies. This attenuation might be explained by the higher baseline risk of adverse outcomes such as preterm birth in twin pregnancies. Some exposures, such as ART use and GDM, appear to be "protective" against perinatal mortality in twin pregnancies, despite being established risk factors for adverse outcomes in singleton pregnancies, potentially related to access to specialist care. There is a paucity of evidence available to counsel mothers of twin pregnancies regarding reduced fetal movement.

CONCLUSIONS

Overall, the risk factors for adverse pregnancy outcomes differ between twin and singleton pregnancies. This highlights the need for further studies to examine the association between risk factors and adverse outcomes in twin pregnancies. The resulting data would facilitate tailored guidance for twin pregnancies, contribute to improved antenatal care, and inform wider public health strategies.

The impact of extending the second stage of labor on repeat cesarean section and maternal and neonatal outcome

OBJECTIVE

To evaluate the effects of extending the second stage of labor in women attempting a trial of labor after a cesarean section (TOLAC).

METHOD

A retrospective cohort study comparing maternal and neonatal outcomes following TOLAC over two periods: period I whose prolonged second stage was considered 2 h, and period II whose prolonged second stage was considered 3 h. The primary outcome was repeat cesarean delivery (CD) rate.

RESULTS

Incidence of repeat CD was significantly lower in period II (18.1% vs 29.7%, P < 0.001). Incidence of uterine rupture was significantly higher in period II (P < 0.001). Instrumental delivery rates were significantly higher in period II (26.2% vs 15.6%, odds ratio [OR] 1.67, 95% CI 1.21-3.56, P < 0.001). Rates of third- and fourth-degree perineal lacerations, chorioamnionitis, and length of hospital stay were similar between groups. Incidence of fetal acidemia was significantly higher in period II (1.5% vs 0.7%, OR 2.14, 95% CI 1.32-5.63, P < 0.001), and incidence of neonatal intensive care unit (NICU) admission was significantly higher (2.5% vs 1.6%, P = 0.004).

CONCLUSION

Extension of the second stage of labor is associated with a decrease in repeat CD rate with a concomitant increase in instrumental delivery rates, uterine rupture, fetal acidemia, and NICU admissions. These findings may warrant further consideration of allowing a prolonged second stage in patients attempting TOLAC.

Urine podocyte mRNA loss in preterm infants and related perinatal risk factors

BACKGROUND

Preterm birth has been identified as a risk factor for development of long-term chronic kidney disease. Podocyte loss has been reported to contribute to this process in preterm animal models. However, details about podocyte loss in preterm infants and related perinatal risk factors have not been well clarified.

METHODS

Forty full-term infants and 106 preterm infants were enrolled. Urine samples were collected from full-term infants within 4-7 days of birth and preterm infants at 37-40 weeks of corrected age. Levels of urine podocin mRNA, urine protein (UP), and urine microalbumin (UMA) were measured, and the relationship between these markers was evaluated. Clinical information in these infants was collected, and potential correlates that may lead to increased podocyte loss during the perinatal period were identified using linear regression analysis.

RESULTS

Urine podocyte loss indicated by the urine podocin mRNA to creatinine ratio (UpodCR) was higher in preterm infants than in full-term infants. UpodCR was correlated with the levels of UP and UMA. Multiple linear regression analysis also showed that lower gestational age (GA) at birth and small for gestational age (SGA) were high risk factors for urine podocyte loss.

CONCLUSIONS

Increasing urine podocyte loss was identified in preterm infants. Moreover, perinatal factors were associated with podocyte loss and may be a potential direction for comprehensive research and intervention in this field. A higher resolution version of the Graphical abstract is available as Supplementary information.

Decreased fetal movements-the utility of ultrasound to identify infants at risk and prevent stillbirth is poor

BACKGROUND

Despite a paucity of evidence, it is widely accepted that a perceived reduction in fetal movements is associated with an increased risk of stillbirth and poor obstetrical outcome. Consequently, many international guidelines recommend urgent ultrasound assessment of fetal well-being in women presenting with decreased fetal movements.

OBJECTIVE

This study aimed to compare rates of abnormal ultrasound findings reflective of fetal compromise between women presenting with decreased fetal movements and gestation-matched controls in the third trimester.

STUDY DESIGN

This was a retrospective cohort study performed at the Mater Mothers' Hospital in Brisbane between 2017 and 2020. We undertook propensity score matching analysis comparing abnormal ultrasound parameters in women with singleton, nonanomalous pregnancies presenting with decreased fetal movements after 28 weeks' gestation. The primary outcome was a composite of any abnormal scan parameter: umbilical artery pulsatility index >95th centile, middle cerebral artery pulsatility index <5th centile, cerebroplacental ratio <10th centile, estimated fetal weight <10th centile for gestation, middle cerebral artery peak systolic velocity >1.5 multiples of the median, or deepest vertical pocket of amniotic fluid <2 or >8 cm.

RESULTS

After propensity score matching, the study cohort comprised 1466 cases and 2207 controls. The rate of the primary composite outcome was not significantly different between the 2 cohorts (20.2% vs 21.3%; P=.42). There were 30 new cases of small-for-gestational-age detected in the decreased fetal movements cohort, giving a number needed to scan of 48 in the decreased fetal movements group to detect 1 case of small-for-gestational-age. However, the frequency of the composite outcome was higher (13.0% vs 5.4%) at the final scan before birth in women with multiple decreased fetal movement presentations. Despite this, there was no significant difference in clinical outcomes between the 2 cohorts.

CONCLUSION

Ultrasound abnormalities are not increased in women with decreased fetal movements compared with controls.

Pregnancy, birth and neonatal outcomes associated with reduced fetal movements: A systematic review and meta-analysis of non-randomised studies

PROBLEM

Maternal perception of reduced fetal movements (RFM) is identified as an important alarm signal for possible risk of impending adverse perinatal outcomes.

BACKGROUND

Perinatal outcomes associated with RFM are increasingly being investigated in non-randomised studies with several associated outcomes, including stillbirth, preterm birth, fetal growth restriction and neonatal death being reported. Findings from studies, however, are conflicting.

AIM

To synthesise the findings of published studies regarding pregnancy, birth and neonatal outcomes in women who presented with RFM.

METHODS

PubMed, EMBASE, CINAHL complete, Maternity and Infant Care, PsycINFO, and Science Citation Index databases were searched up to 8th July 2021 and updated again on 8th September 2022. Non-randomised studies involving pregnant women ≥24 weeks' gestation, who presented with a primary complaint of RFM compared to women who did not present with RFM were included. Data were meta-analysed using a random-effects model and presented as Odds Ratios (OR) or Standard Mean Differences (SMD) with 95% Confidence Intervals (CI).

FINDINGS

Thirty-nine studies were included. Women with RFM had increased odds of stillbirth (OR 3.44, 95% CI 2.02-5.88) and small for gestational age (OR 1.37, 95% CI 1.16-1.61) when compared with women who did not have RFM. Associations were also found for induction of labor, instrumental birth and caesarean section but not for preterm birth (OR 0.92, 95% CI 0.71-1.19) or neonatal death (OR 0.99; 95% CI 0.52-1.90).

CONCLUSION

This review revealed that RFM is associated with increased odds of stillbirth, small for gestational age, induction of labor, instrumental birth and caesarean section but not preterm birth or neonatal death.

Evaluation of the relationship between reduced fetal movement and obstetric-neonatal outcomes and placental pathologies

BACKGROUND

Fetal movements are one of the simple methods that show the baby's well-being. Conditions associated with decreased fetal movements have not been determined, so it is important to analyze their different aspects. This study aimed to evaluate the relationship between reduced fetal movement and obstetric-neonatal outcomes, and placental pathologies.

METHODS

In this prospective controlled study, laboratory results (blood glucose, hemoglobin, thyroid-stimulating hormone [TSH]), a non-stress test (NST), biophysical profile results, obstetric and neonatal outcomes, and placental pathological results of 74 pregnant women at 35 or more gestational weeks (to exclude the effect of prematurity on obstetric and neonatal outcomes) attending the obstetrics clinic between December 26, 2017 and January 30, 2019 with complaints of reduced fetal movement, were compared with 74 healthy pregnant women. Since prematurity and post-maturity may adversely affect obstetric-neonatal and placental pathology results, term pregnancies between 37^0/7-40^6/7 weeks were evaluated separately.

RESULTS

In the group with reduced fetal movement, the biophysical profile was lower than the controls (P=0.013). Among placental pathologies, chorangiosis and hypercoiled cord were significantly higher in the group with reduced fetal movement than controls (P<0.05). Small for gestational age (SGA) and fetal growth restriction (FGR) in this group had these pathologies. Results of women at 37^0/7-40^6/7 weeks were similar except for the additional finding of chorioamnionitis.

CONCLUSIONS

Reduced fetal movement may be associated with the low biophysical profile. In cases where fetal movement decreases, placental chorangiosis and hypercoiled cord seem to be associated with fetal growth restriction.

FETAL MOVEMENT SIGNAL DETECTION METHOD BASED ON MULTIPLE PRESSURE SENSORS

Objective: Fetal movement (FM) is one of the objective phenomena of fetal life. The decrease of FM is a clinical indicator of fetal hypoxia. A fetal motion detection method is based on multiple pressure sensors and multi features. Methods: Collecting the abdominal data of pregnant women using multi-pressure sensors, preprocessing the signal with a digital filter, extracting the time–frequency characteristics of FM signal. The designed classifier is used for recognition of the extracted features. Results: The detection system used for FM time series can provide reliable results with a detection rate of 93.0% and a positive rate is 75.9%. Conclusion: The portable detection system proposed in this paper is a good alternative that will optimize medical use, professionals and hospital resources and has potential application prospects in the field of home electronic medical treatment.

Evaluation of Pregnancy Outcomes Among Women With Decreased Fetal Movements

IMPORTANCE

Stillbirth is a devastating pregnancy outcome with far-reaching economic and psychosocial consequences, but despite significant investment, a screening tool for identifying those fetuses at risk for stillbirth remains elusive. Maternal reporting of decreased fetal movements (DFM) has been found to be associated with stillbirth and other adverse perinatal outcomes.

OBJECTIVE

To examine pregnancy outcomes of women presenting with DFM in the third trimester at a tertiary Australian center with a clear clinical management algorithm.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study used data on all births meeting the inclusion criteria from 2009 through 2019 at Mater Mothers' Hospital in Brisbane, Australia. This is a tertiary center and Australia's largest maternity hospital. All singleton births without a known congenital anomaly after 28 weeks' gestation were included. Among 203 071 potential participants identified from the hospital database, 101 597 individuals met the eligibility criteria. Data analysis was performed from May through September 2020.

EXPOSURE

Presentation to hospital with DFM after 28 weeks gestation.

MAIN OUTCOMES AND MEASURES

The primary outcome of this study was the incidence of stillbirth. Multivariate analysis was undertaken to determine the association between DFM and stillbirth, obstetric intervention, and other adverse outcomes, including being born small for gestational age (SGA) and a composite adverse perinatal outcome (at least 1 of the following: neonatal intensive care unit admission, severe acidosis [ie, umbilical artery pH <7.0 or base excess -12.0 mmol/L or less], 5-minute Apgar score <4, or stillbirth or neonatal death). The hypothesis being tested was formulated prior to data collection.

RESULTS

Among 101 597 women with pregnancies that met the inclusion criteria, 8821 (8.7%) presented at least once with DFM and 92 776 women (91.3%) did not present with DFM (ie, the control population). Women presenting with DFM, compared with those presenting without DFM, were younger (mean [SD] age, 30.4 [5.4] years vs 31.5 [5.2] years; P < .001), more likely to be nulliparous (4845 women [54.9%] vs 42 210 women [45.5%]; P < .001) and have a previous stillbirth (189 women [2.1%] vs 1156 women [1.2%]; P < .001), and less likely to have a previous cesarean delivery (1199 women [13.6%] vs 17 444 women [18.8%]; P < .001). During the study period, the stillbirth rate was 2.0 per 1000 births after 28 weeks' gestation. Presenting with DFM was not associated with higher odds of stillbirth (9 women [0.1%] vs 185 women [0.2%]; adjusted odds ratio [aOR], 0.54; 95% CI, 0.23-1.26, P = .16). However, presenting with DFM was associated with higher odds of a fetus being born SGA (aOR, 1.14; 95% CI, 1.03-1.27; P = .01) and the composite adverse perinatal outcome (aOR, 1.14; 95% CI, 1.02-1.27; P = .02). Presenting with DFM was also associated with higher odds of planned early term birth (aOR, 1.26; 95% CI, 1.15-1.38; P < .001), induction of labor (aOR, 1.63; 95% CI, 1.53-1.74; P < .001), and emergency cesarean delivery (aOR, 1.18; 95% CI, 1.09-1.28; P < .001).

CONCLUSIONS AND RELEVANCE

The presence of DFM is a marker associated with increased risk for a fetus. This study's findings of a nonsignificantly lower rate of stillbirth among women with DFM may be reflective of increased community awareness of timely presentation to their obstetric care clinician when concerned about fetal movements and the benefits of tertiary level care guided by a clear clinical management protocol. However, DFM was associated with increased odds of an infant being born SGA, obstetric intervention, early term birth, and a composite of adverse perinatal outcomes.

Obstetrics, genetics, and litigation

INTRODUCTION

Claims of medical negligence are universal. Unexpected adverse pregnancy outcome may trigger litigation. Such outcomes, especially with neurodevelopmental sequelae, may be compounded by a genetic disorder, congenital abnormality, or syndrome.

MATERIAL AND METHODS

This is a report of 297 cases in which a pregnancy complication, error, or incident occurred that was followed by progeny with a genetic disorder, congenital abnormality, or syndrome that spawned litigation. The author assessed, opined, and in many cases, testified about causation.

RESULTS

Pregnancies complicated by hypoxic ischemic encephalopathy were not infrequently compounded by offspring with a genetic disorder, congenital abnormality, or syndrome. Multiple cases were brought because of missed ultrasound or laboratory diagnoses, or failures in carrier detection. Teratogenic medication prescribed before or during pregnancy invited legal purview. Failure to refer (or confer) for genetic evaluation or counseling in the face of significant risk, occurred repeatedly. Ethical breaches and hubris promptly led to litigation.

CONCLUSIONS

Many lessons and recommendations emerge in this report. These include the realization that the vast majority of errors in this series involved at least two caregivers, serial ultrasound studies are important, decreased fetal movements may signal a genetic disorder, congenital abnormality, or syndrome, family history and ethnicity are vital, cognitive biases profoundly affect decision-making. Finally, the simplest of errors have the potential for causing life-long grief.

Could a multidisciplinary regional audit identify avoidable factors and delays that contribute to stillbirths? A retrospective cohort study

Background

The annual rate of stillbirth in Sweden has remained largely unchanged for the past 30 years. In Sweden, there is no national audit system for stillbirths. The aim of the study was to determine if a regional multidisciplinary audit could help in identifying avoidable factors and delays associated with stillbirths.

Methods

Population-based retrospective cohort study.

Settings: Six labour wards in Stockholm County.

Participants: Women delivering a stillbirth > 22 weeks of gestation in Stockholm during 2017.

Intervention: A multidisciplinary team was convened. Each team member independently assessed the medical chart of each case of stillbirth regarding causes and preventability, level of delay, the standard of healthcare provided, the investigation of maternal/foetal diseases and if any recommendations were given for the next pregnancy. A decision was based on the agreement of all five members. If no agreement was reached, a reassessment of the case was done and the medical record was scrutinized again until a mutual decision was made.

Primary outcomes: The frequency of probably/possibly preventable factors associated with a stillbirth and the level of delay (patient/caregiver).

Secondary outcomes: The causes of death, the standard of antenatal/intrapartum/postpartum care, whether a summary of possible causes of the stillbirth was made and if any plans for future pregnancies were noted.

Results

Thirty percent of the stillbirths were assessed as probably/possibly preventable. More frequent ultrasound/clinical check-ups, earlier induction of labour and earlier interventions in line with current guidelines were identified as possibly preventable factors. A possibly preventable stillbirth was more common among non-Swedish-speaking women (p = 0.03). In 15% of the cases, a delay by the healthcare system was identified. Having multiple caregivers, absence of continuity in terms of attending the antenatal clinic and not following the basic monitoring program for antenatal care were also identified as risk factors for a delay.

Conclusion

A national/regional multidisciplinary audit group retrospectively identified factors associated with stillbirth. Access to good translation services or a more innovative approach to the problem regarding communication with mothers could be an important factor to decrease possible patient delays contributing to stillbirths.

Reduced Fetal Movements and Perinatal Mortality

Introduction:

Counting of fetal movement (FM) during pregnancy is believed to be a method by which a woman estimates the fetal well-being. In 2015, it was estimated that 2.6 million babies had died in utero. A percentage of 30-55% of women who experience an episode of reduced fetal movement (RFM) within a week may face stillbirth.

Aim:

The aim of this review was to assess the impact of reduced fetal movements and of educational interventions on maternal counting of fetal movements on perinatal mortality, perinatal outcome and mode of delivery.

Methods:

A search of electronic databases was conducted for detecting studies that examine the coincidence of reduced fetal movements (RFM) in combination with stillbirth and perinatal morbidity.

Results:

The findings of this review suggest that there is an association between the incidence of stillbirth and the experience of alterations in fetal movements’ quantity and quality in the preceding weeks. Interventions on fetal movement counting, concerning both the number and the density of fetal movements, may reduce the adverse perinatal outcomes to an extent, after informing and making aware of the pregnant women for their meaning.

Conclusion:

Maternity care professionals should: a) inform pregnant women about the importance of FM counting, b) encourage pregnant women to be familiarized on the recognition of theirs’ baby normal pattern of fetal movements and c) alarm women when this pattern changes. Care professionals should emphasize that counting of fetal movements is not related only to movements’ quantity (number) but also to movements’ quality (density).
