Evaluation of Elastic Venous Compression Device dispensation in pregnant and post-partum women using the French National Health Insurance Claims Database: The ProFIL retrospective cohort study

OBJECTIVES

To describe the real-world use of Elastic Venous Compression Devices (EVCDs) during pregnancy and post-partum using data from a representative subset of the French National Health Insurance Claims Database (the Echantillon Généraliste des Bénéficiaires, EGB).

STUDY DESIGN

Women aged 15-49 who were pregnant between 1st July 2017 and 15th June 2018 were identified in the EGB using pregnancy-specific acts (certain prenatal examinations or deliveries). Subgroups were defined by age, presence of Venous Thrombo-Embolism (VTE) risk factors, history of VTE, delivery type and time period. EVCD dispensations (format, prescriber, and date) were identified among those for "standard orthotics" using their unique reimbursement tariffs. Dispensation rates were computed for all subgroups, overall and by format and were compared.

RESULTS

15,528 pregnant women were included: 7,252 [46.7 %] deliveries (5,796 vaginal [79.9 %], 482 planned cesarean sections (C-sections) [6.7 %] and 974 unplanned C-Sections [13.4 %]), 2,734 (17.6 %) terminations and 5,542 (35.7 %) unknown outcomes. Overall, 4,919 (31.7 %) women were dispensed at least one EVCD. Ante-partum dispensation occurred in 43.1 % (n = 3,122) of women whose pregnancy led to a delivery. Dispensation rates were 17.3 % (n = 1,005), 46.7 % (n = 225) and 44.1 % (n = 430) after vaginal delivery, planned C-sections or unplanned C-sections, respectively. Overall, dispensation rates significantly increased with age, the presence of VTE risk factors, and a history of VTE (p < 0.01). EVCD dispensation was most frequent (17.0 %) during the 5th month of pregnancy. Among pregnant women who were dispensed at least one EVCD during ante- or post-partum, 69.0 % had one or two units of compression (27.1 % [one unit], 41.9 % [two units]). Stockings (48.6 %, n = 6,038) were dispensed significantly more frequently than socks (36.9 %, n = 4,586) and tights (14.5 %, n = 1,806) (p < 0.01). The main contributors to mechanical VTE prophylaxis were gynecologists (26.3 % of dispensations, n = 2,280), general practitioners (20.2 %, n = 1,749) and midwives (15.1 %, n = 1,314).

CONCLUSIONS

Low observed dispensation rates highlight a discrepancy between the French National Authority for Health (Haute Autorité de Santé, HAS), recommending EVCDs use during pregnancy and after delivery, and the real-life use of EVCD. Prescription sensitization combined with targeted information campaigns for pregnant women would be beneficial to contribute to the prevention of VTE, a health problem for pregnant women.

[Maternal mortality in France, 2016-2018, frequency, causes and women's profile]

OBJECTIVE

To describe, for the 2016-2018 period, the frequency, causes and risk factors of maternal deaths in France.

METHOD

Data from the National Confidential Enquiry into Maternal Deaths for 2016-2018.

RESULTS

For 2016-2018, 272 maternal deaths occurred in France up to 1 year after the end of pregnancy, i.e a maternal mortality ratio of 11.8 per 100,000 live births (95 % CI 10.4-13.3), and 8.5 (IC 95 % 7.4-9.8) for maternal mortality up to 42 days. Compared to women aged 20-24, the risk of maternal death is multiplied by 2.6 for women aged 35-39, by 5 for women aged 40 and over. Obese women are twice as frequent among maternal deaths (26 %) than in the general population of parturients (11 %). There are territorial disparities -the maternal mortality ratio in the French overseas departments is 2 times higher than in metropolitan France (significant difference but smaller than in 2013-2015)-, and social disparities -the mortality of migrant women remains higher than that of women born in France, particularly for women born in sub-Saharan Africa whose risk is 3 times higher than that of native women. One in three women who died (34 %) had socio-economic vulnerability versus 22 % in the overall population of parturients. Among causes of maternal deaths, the predominant role of psychiatric conditions (mostly suicides) is confirmed for the period 2016-2018, leading cause of maternal mortality considered up to 1 year (17 %), MMR of 1.9/100,000 NV. i.e. approximately one death from psychiatric causes every 3 weeks. Cardiovascular diseases are the second leading cause of maternal mortality up to one year (14 %) and the leading cause up to 42 days (16 %), with 1.3 deaths per 100,000 NV. Amniotic fluid embolism ranks as the third cause (8 %) (2nd cause, 11 %, for MM limited to 42 days), i.e. MMR of 0.9 per 100,000 NV. After a regular decline over the last decade, maternal mortality from obstetric hemorrhage is at a stable level compared to the previous triennium 2013-2015, MMR of 0.9/100,000 NV, i.e 5th cause of MM up to one year (7 %) and 4th cause of MM up to 42 days.

CONCLUSION

The overall national maternal mortality ratio does not show a downward trend, even with constant surveillance method. Territorial inequalities persist but change in their magnitude and in the regions concerned. The profile of the causes of maternal mortality up to one year of the pregnancy end shows the leading role of suicides and cardiovascular diseases, which illustrates that the health of pregnant women or those who have recently given birth is not limited to the obstetric domain, and highlights the importance of multidisciplinarity in the management and organization of care for women in this period.

Severe postpartum hemorrhage and the risk of adverse maternal outcome: A comparative analysis of two population-based studies in France and the Netherlands

Objectives

Among women with severe PPH (sPPH) in France and the Netherlands, we compared incidence of adverse maternal outcome (major obstetric hemorrhage (≥2.5L blood loss) and/or hysterectomy and/or mortality) by mode of delivery. Second, we compared use and timing of resuscitation and transfusion management, second-line uterotonics and uterine-sparing interventions (intra-uterine tamponade, compression sutures, vascular ligation, arterial embolization) by mode of delivery.

Methods

 Secondary analysis of two population-based studies of women with sPPH in France and the Netherlands. Women were selected by a harmonized definition for sPPH: (total blood loss ≥ 1500 ml) AND (blood transfusion of ≥ 4 units packed red blood cells and/or multicomponent blood transfusion).

Findings

Incidence of adverse maternal outcome after vaginal birth was 793/1002, 9.1 % in the Netherlands versus 88/214, 41.1 % in France and 259/342, 76.2% versus 160/270, 59.3% after cesarean. Hemostatic agents such as fibrinogen were administered less frequently (p < 0.001) in the Netherlands (vaginal birth: 83/1002, 8.3% versus 105/2014, 49.5% in France; cesarean: 47/342, 13.7% and 152/270, 55.6%). Second-line uterotonics were started significantly later after PPH-onset in the Netherlands than France (vaginal birth: 46 versus 25 min; cesarean: 45 versus 18 min). Uterine-sparing interventions were less frequently (p < 0.001) applied in the Netherlands after vaginal birth (394/1002,39.3 %, 134/214, 62.6%) and cesarean (133/342, 38.9 % and 155/270, 57.4%), all initiated later after onset of refractory PPH in the Netherlands.

Interpretation

Incidence of adverse maternal outcome was higher among women with sPPH in the Netherlands than France regardless mode of birth. Possible explanatory mechanisms are earlier and more frequent use of second-line uterotonics and uterine-sparing interventions in France compared to the Netherlands.

Evaluating the quality of care for postpartum hemorrhage with a new quantitative tool: a population-based study

To develop a new tool to assess the global quality of care for post-partum hemorrhage (PPH)-the leading preventable cause of maternal mortality worldwide-and to identify characteristics of maternity units associated with inadequate PPH management. This is a secondary analysis of the EPIMOMS population-based study conducted in 2012-2013 in 119 french maternity units (182,309 women who gave birth). We included women with severe PPH. We first developed a score to quantify the quality of care for PPH. Then, we identified characteristics of the maternity units associated with "inadequate care" defined by a score below the 25th percentile, with multi-level logistic regression adjusted for individual characteristics. The score combined 8 key components of care and took into account delivery mode and PPH cause. For PPH after vaginal delivery, the risk of inadequate care was increased in low versus high-volume maternity units (< 1000 deliveries/year: aOR-2.20 [1.12-4.32], [1000-2000 [deliveries/year: aOR-1.90 [1.02-3.56] compared to ≥ 3500 deliveries/year), in private versus public units (aOR-1.72 [1.00-2.97]), and in low versus high-level of care units (aOR-2.04 [1.24-3.35]). For PPH after cesarean, the only characteristic associated with an increased risk of inadequate care was the absence of 24/24-onsite anesthesiologist (aOR-4.34 [1.41-13.31]). These results indicate where opportunities for improvement are the greatest.

The challenge of care coordination by midwives during the COVID-19 pandemic: a national descriptive survey

BACKGROUND

As part of a decades-long process of restructuring primary care, independent (also known as community) healthcare workers are being encouraged to work in groups to facilitate their coordination and continuity of care in France. French independent midwives perform about half of the early prenatal interviews that identify mothers' needs during pregnancy and then refer them to the appropriate resources. The French government, however, structured the COVID-19 pandemic response around public health institutions and did not directly mobilise these community healthcare workers during the lockdown phase. These responses have raised questions about their role within the healthcare system in crises. This survey's main objectives were to estimate the proportion of independent midwives who experienced new difficulties in referring women to healthcare facilities or other caregivers and in collaborating with hospitals during the first stage of this pandemic. The secondary objective was to estimate the proportion, according to their mode of practice, of independent midwives who considered that all the women under their care had risked harm due to failed or delayed referral to care.

METHODS

We conducted an online national survey addressed to independent midwives in France from 29 April to 15 May 2020, around the end of the first lockdown (17 March-11 May, 2020).

RESULTS

Of the 5264 registered independent midwives in France, 1491 (28.3%) responded; 64.7% reported new or greater problems during the pandemic in referring women to health facilities or care-providers, social workers in particular, and 71.0% reported new difficulties collaborating with hospitals. Nearly half (46.2%) the respondents considered that all the women in their care had experienced, to varying degrees, a lack of or delay in care that could have affected their health. This proportion did not differ according to the midwives' form of practice: solo practice, group practice with other midwives only, or group practice with at least two types of healthcare professionals.

CONCLUSIONS

The pandemic has degraded the quality of pregnant women's care in France and challenged the French model of care, which is highly compartmentalised between an almost exclusively independent primary care (community) sector and a predominantly salaried secondary care (hospital) sector.

Nationwide confidential enquiries into maternal deaths because of obstetric hemorrhage in the Netherlands between 2006 and 2019

INTRODUCTION

Obstetric hemorrhage-related deaths are rare in high income countries. Yet, with increasing incidences of obstetric hemorrhage in these countries, it is of utmost importance to learn lessons from each obstetric hemorrhage-related death to improve maternity care. Our objective was to calculate the obstetric hemorrhage-related maternal mortality ratio (MMR), assess causes of obstetric hemorrhage-related deaths, and identify lessons learned.

MATERIAL AND METHODS

Nationwide mixed-methods prospective case-series with confidential enquiries into maternal deaths due to obstetric hemorrhage in the Netherlands from January 1, 2006 to December 31, 2019.

RESULTS

The obstetric hemorrhage-related MMR in the Netherlands in 2006-2019 was 0.7 per 100 000 livebirths and was not statistically significantly different compared with the previous MMR of 1.0 per 100 000 livebirths in 1993-2005 (odds ratio 0.70, 95% confidence interval 0.38-1.30). Leading underlying cause of hemorrhage was retained placenta. Early recognition of persistent bleeding, prompt involvement of a senior clinician and timely management tailored to the cause of hemorrhage with attention to coagulopathy were prominent lessons learned. Also, timely recourse to surgical interventions, including hysterectomy, in case other management options fail to stop bleeding came up as an important lesson in several obstetric hemorrhage-related deaths.

CONCLUSIONS

The obstetric hemorrhage-related MMR in the Netherlands in 2006-2019 has not substantially changed compared to the MMR of the previous enquiry in 1993-2005. Although obstetric hemorrhage is commonly encountered by maternity care professionals, it is important to remain vigilant for possible adverse maternal outcomes and act upon an ongoing bleeding following birth in a more timely and adequate manner. Our confidential enquiries still led to important lessons learned with clinical advice to professionals as how to improve maternity care and avoid maternal deaths. Drawing lessons from maternal deaths should remain a qualitative and moral imperative.

Overweight, obesity and excessive weight gain in pregnancy as risk factors for adverse pregnancy outcomes: a narrative review

The global prevalence of overweight and obesity in pregnancy is rising and this represents a significant challenge for the management of pregnancy and delivery. Women who have a pre‐pregnancy body mass index greater than 25 kg m^–2 are more likely than those with a body mass index in the ideal range (20–24.99 kg m^–2) to have problems conceiving a child and are at greater risk of miscarriage and stillbirth. All pregnancy complications are more likely with overweight, obesity and excessive gestational weight gain, including those that pose a significant threat to the lives of mothers and babies. Labour complications arise more often when pregnancies are complicated by overweight and obesity. Pregnancy is a stage of life when women have greater openness to messages about their lifestyle and health. It is also a time when they come into greater contact with health professionals. Currently management of pregnancy weight gain and the impact of overweight tends to be poor, although a number of research studies have demonstrated that appropriate interventions based around dietary change can be effective in controlling weight gain and reducing the risk of pregnancy complications. The development of individualised and flexible plans for avoiding adverse outcomes of obesity in pregnancy will require investment in training of health professionals and better integration into normal antenatal care.

Overweight and obesity before pregnancy and excessive gestational weight gain are major determinants of risk for pregnancy loss, gestational diabetes, hypertensive conditions, labour complications and maternal death.

Pregnancy is regarded as a teachable moment when women are at their most receptive to messages about their health. However, unclear guidance on diet and physical activity, weight stigma from health professionals, inexperience and reluctance among professionals about raising issues about weight, and stretched resources put the health of women and babies at risk.

Excessive weight gain in pregnancy and post‐partum weight retention compromise future fertility and increase risk for future pregnancies.

Large randomised controlled trials have had little success in addressing excessive gestational weight gain or antenatal complications. Individualised, culturally sensitive and responsive interventions appear to have greater success.

[Maternal deaths due to suicide in France 2013-2015]

Pregnancy represents a period of significant psychological vulnerability for women. During the perinatal period, twenty percent of them would present with mental disorders ranging from anxiety to depression. In those with pre-existing mental illness, the risk of acute decompensation is significant. For this reason, the World Health Organization recommends classifying suicides occurring during pregnancy and up to one-year post-partum as maternal deaths. Thus, between 2013 and 2015, 35 maternal suicides occurred in France, representing a maternal mortality ratio of 1:4 per 100,000 live births (95% CI: 1.0-2.0). By constituting 13.4% of all maternal deaths for the period, this group is the one of the 2 leading causes of maternal mortality. A total of 23% occurred in the first 42 days post-partum, and 77% between 43 days and one year after birth. 33.3% of the suicidal mothers had a known psychiatric history and 30.3% had a history of psychiatric care, unknown to obstetrical teams. Non-optimal care was present in 72% of cases with 91 % of suicides were potentially preventable, preventability factors beinga lack of multidisciplinary care and inadequate interaction between the patient and the care system. Strong messages were drawn from the analysis of these cases to optimize care: improve knowledge of the psychiatric history from the time of enrolment in maternity units, improve the identification of warning symptoms and the use of the psychologist and/or psychiatrist, set up a specific care pathway and multidisciplinary collaboration in case of known psychiatric disease.

[Maternal Deaths due to Amniotic Fluid Embolism in France 2013-2015]

Amniotic fluid embolism remains the 3rd cause of maternal death in France, with a stable rate and 28 deaths in this triennium, representing 10.7% of maternal deaths and a maternal mortality ratio of 1.2/100,000 live births. Cases are characterized by the suddenness of symptoms: the median delay between symptoms and death was 4h [0.75-696] with 20/28 patients did not reach the intensive care unit. Initial circulatory failure or cataclysmic haemorrhage was the two modes of presentation. Prodromes were reported in 17 (63%) cases and induction of labour was present in 12/27 (44%). One or more factors of sub-optimal care were present in 72% of the cases, and 52% of deaths were considered possibly or probably preventable. This preventability most often concerned the content of care but also the organisation of care (including human resources, communication, sites of care and referrals). The delay in establishing a well-conducted cardio-circulatory resuscitation or the delay in setting up an optimal transfusion strategy were the most frequent elements of substandard care. Absence or delay at hysterectomy during haemorrhagic situations was reported in 15/20 cases. The experts suggest being on the alert to diagnose amniotic embolism at an early stage, initiating intense resuscitation "outside the walls", envisaging a hysterectomy without delay if the haemorrhage is intense. On an organisational level, a "vital emergency maternity care" plan, specific to each establishment could be proposed.

[Maternal deaths due to haemorrhage in France 2013-2015]

Maternal death from haemorrhage is decreasing: in the last 15 years the number of deaths has been halved. This improvement demonstrates the progress made in hemorrhage management as a result of collective efforts. The number of deaths in this triennium is 22, representing 8.4% of maternal deaths and a maternal mortality ratio by haemorrhage of 1.0/100,000 live births. Nevertheless, there is a worrying proportion of deaths from occult haemorrhage. These occult haemorrhages most often occurred after caesarean sections. A lack of surveillance in the immediate follow-up was generally associated. One or more factors of sub-optimal care were present in 84% of the cases, and 88.9% of deaths were considered possibly or probably preventable. Delay in the diagnosis of haemorrhage, delay in surgical treatment, an insufficient transfusion strategy and inappropriate locations of care were the most frequently reported factors. The experts suggest that risk factors for haemorrhage should be identified in order to propose the most appropriate facility for childbirth. They encourage the strategies for early diagnosis of haemorrhage (attentive and regular monitoring, rapid haemoglobin measurement, abdominal ultrasound) and surgical intervention in case of hemoperitoneum.
