Proactive management of extreme prematurity: disagreement between obstetricians and neonatologists

Resuscitation of the Small Baby: A Team Approach

Recent advancements in medicine have improved the survival of extremely low gestational age neonates, or small babies (22-27 weeks' gestation). Once inconceivable that an infant born as early as 22 weeks' gestation could survive, infants born at periviable gestational ages are now increasingly surviving to discharge from the NICU. Subsequently, clinical focus is pivoting toward practices that decrease morbidity in this extremely vulnerable population. This article aims to discuss obstetrical and neonatal practices during delivery to improve outcomes of the small baby and emphasize the importance of collaboration among all disciplines involved in the pregnancy, delivery, and postnatal care of the small baby. Effective communication and teamwork are cornerstones to improving outcomes in this patient population.

Maternal fetal medicine, obstetric, and neonatology perspectives on joint prenatal counseling at periviable gestational ages

OBJECTIVE

To explore perspectives of maternal fetal medicine specialists (MFMs), obstetricians (OBs), and neonatologists (Neos) about antenatal counseling at periviable gestational ages and examine how those perceptions impact multidisciplinary counseling.

STUDY DESIGN

Semi-structured interviews were conducted and thematic analysis performed until thematic saturation.

RESULTS

Interviews of 7 Neos and 8 OB/MFMs identified three themes: (1) roles in periviability counseling; (2) training and lifelong learning to develop/enhance communication skills; and (3) managing interdisciplinary dynamics. Participants agreed on consult content and the appropriate subspecialist to discuss specific topics but differed in their approaches. Subspecialty perspectives differed on resuscitation, survival, and developmental outcomes. Formal communication skills training was identified as a means to scaffold conversations into a uniform approach.

CONCLUSION

Despite near universal agreement that joint perviability counseling would be beneficial, logistical barriers and lack of a shared framework may hinder its implementation. Formal communication skills training may support organized joint counseling.

Viability of Extremely Premature neonates: clinical approaches and outcomes

Viability refers to an infant's ability to survive outside the womb, which is influenced by both developmental maturity and the quality of medical care received. The concept of periviability, which has evolved alongside medical advancements, describes the stage between viability and nonviability, typically spanning from 200/7 to 25 6/7 weeks of gestation. While the chances of survival are extremely low at the earlier end of this range, the possibility of surviving without significant long-term complications improves towards the later end. The effectiveness of various antenatal and postnatal care practices, particularly those considered to be part of an active approach, plays a crucial role in influencing survival rates and mitigating morbidities. However, the decision to provide such active care is heavily influenced by national guidelines as well as international standards. The variability in guideline recommendations from one country to another, coupled with differences based on gestational age or accompanying risk factors, prevents the establishment of a standardized global approach. This variability results in differing practices depending on the country or institution where the birth occurs. Consequently, healthcare providers must navigate these discrepancies, which often leads to complex ethical dilemmas regarding the balance between potential survival and the associated risks. This review article explores the evolution of the definition of viability, the vulnerabilities faced by periviable infants, and the advancements in medical care that have improved survival rates. Additionally, it examines the viability and periviability definitions, the care and outcomes of periviable infants and recommendations in guidelines.

Limits of Viability: Perspectives of Portuguese Neonatologists and Obstetricians

INTRODUCTION

Advances in neonatal care have improved the prognosis in extremely preterm infants. The gestational age considered for active treatment has decreased globally. Despite implemented guidelines, several studies show variability in practice. The aim of this study was to understand theperspectives of Portuguese neonatologists and obstetricians regarding the management of extremely preterm infants.

METHODS

An online survey was sent through the Portuguese Neonatology Society and the Portuguese Society of Obstetrics and Maternal-Fetal Medicine from August to September 2023.

RESULTS

We obtained 117 responses: 53% neonatologists, 18% pediatricians, and 29% obstetricians, with 62% having more than 10 years of experience. The majority (80%) were familiar with the Portuguese Neonatology Society consensus on the limits of viability and 46% used it in practice; 62% were unaware of Portuguese morbidity-mortality statistics associated with extremely preterm infants. Most (91%) informed parents about morbiditymortality concerning the gestational age more frequently upon admission (64%) and considered their opinion in the limit of viability situations (95%). At 22 weeks gestational age, 71% proposed only comfort care, while at 25 and 26 weeks, the majority suggested active care (80% and 96%, respectively). Less consensus was observed at 23 and 24 weeks. At 24 weeks, most obstetricians offered active care with the option of comfort care by parental choice (59%), while the neonatology group provided active care (65%), p < 0.001. Regarding the lower limit of gestational age for in utero transfer, corticosteroid administration, cesarean section for fetal indication, neonatologist presence during delivery, and endotracheal intubation; neonatologists considered a lower gestational age than obstetricians (23 vs 24 weeks; p = 0.036; p < 0.001; p < 0.001; p = 0.021; p < 0.001, respectively).

CONCLUSION

Differences in perspectives between obstetricians and neonatologists in limits of viability situations were identified. Neonatologists considered a lower gestational age in various scenarios and proposed active care earlier. Standardized counseling for extremely preterm infants is crucial to avoid ambiguity, parental confusion, and conflicts in perinatal care.

The ethics and practice of perinatal care at the limit of viability: FIGO recommendations

An arbitrary gestational age limit of viability cannot be set, and in clinical practice the focus should be on a periviability interval-the so-called "gray zone" of prognostic uncertainty. For cases within this interval, the most appropriate decision-making process remains debatable and periviability has emerged as one of the greatest challenges in bioethics. Universally recognized ethical principles may be interpreted differently due to socioeconomic, cultural, and religious aspects. In the case of periviability, there is considerable uncertainty over whether interventions result in a greater balance of clinical good over harm. Furthermore, the fetus or neonate is unable to exercise autonomy and the physicians and parents will act as patient surrogates. When parents and physicians disagree about the infant's best interest, a dialogue without paternalistic attitudes is essential, whereby physicians should only offer, but not recommend, perinatal interventions. Parental choice, based on thorough information, should be respected within the limits of what is medically feasible and appropriate. When disagreements between parents and physicians occur, how is consensus to be achieved? Professional guidelines can be helpful as a framework and starting point for discussion. In reality, however, guidelines only rarely draw categorical lines and in many cases remain vague and ambiguously worded. Local ethics committees can provide counseling and function as moderators during discussions, but ethics committees do not have decision precedence. Counseling assumes the most significant role in periviability discussions, taking into consideration the particular fetal and maternal characteristics, as well as parental values. Several caveats should be observed relative to counseling: message fragmentation or inconsistence should be minimized, prognosis should preferably be presented in a positive framing, and overreliance on statistics should be avoided. It is recommended that decisions regarding neonatal resuscitation in the periviability interval be made before birth and not conditional on the newborn's appearance at birth. Regardless of decision, it is important to assure pre- and postnatal coherence. The present article describes how individual physicians, centers, and countries differ in the approach to the decision to initiate or forgo intensive care in the periviability interval. It is impossible to provide a global consensus view and there can be no unifying ethical, moral, or practical strategy. Nevertheless, ethically justified, quality care comprises early involvement of the obstetric and neonatal team to enable a coherent, comprehensible, nonpaternalistic, and balanced plan of care. Ultimately, physicians will need to adjust the expectations to the local standards, local outcome data, and local neonatal support availability.

Neonatal and Obstetric Provider Perceptions and Management at 22 Weeks' Gestation

OBJECTIVE

Active treatment for periviable infants may be influenced by neonatal and obstetric provider perceptions of prognosis. The two aims of this study are to (1) quantify prognostic discordance between provider and data-driven survival estimates and (2) evaluate if prognostic discordance is associated with the threshold probability of survival at which neonatal providers recommend active treatment or obstetric providers recommend antenatal corticosteroids.

STUDY DESIGN

Provider survival estimates and threshold probabilities of survival for active treatment and antenatal steroid use were obtained from a case-based survey for an infant or pregnancy at 22 weeks' gestation that was administered at two Atlanta hospitals. Data-driven survival estimates, including ranges, were acquired through the National Institute of Child Health and Human Development Extremely Preterm Birth Outcomes Tool. Prognostic discordance was calculated as the difference between a provider and data-driven estimates and classified as pessimistic (provider estimate below data-driven estimate range), accurate (within range), or optimistic (above range). The association between prognostic discordance and the threshold probability of survival was evaluated using nonparametric tests.

RESULTS

We had 137 neonatal respondents (51% response rate) and 57 obstetric responses (23% response rate). The overall median prognostic discordance was 1.5% (interquartile range: 17, 13) and 52 (27%) of all respondents were pessimistic, 100 (52%) were accurate, and 42 (22%) were optimistic. The survival threshold above which neonatal and obstetric providers recommended active treatment or antenatal corticosteroids was 30% (20-45%) and 10% (0-20%), respectively. Thresholds did not significantly differ among the three prognostic discordance groups (p = 0.45 for neonatal and p = 0.53 for obstetric providers). There was also no significant correlation between the magnitude of prognostic discordance and thresholds.

CONCLUSION

Prognostic discordance exists among both neonatal and obstetric providers. However, this discordance is not associated with the threshold probability of survival at which providers recommend active treatment or antenatal corticosteroids at 22 weeks' gestation.

KEY POINTS

· Prognostic discordance at 22 weeks' gestation exists for neonatal and obstetric providers.. · Prognostic discordance is not associated with survival thresholds for neonatal active treatment.. · Prognostic discordance is not associated with survival thresholds for the use of antenatal corticosteroids..

The Ethics and Practice of Periviability Care

Since the 1960s, the gestational age at which premature infants typically survive has decreased by approximately one week per decade [...].

Differences in the attitudes towards resuscitation of extremely premature infants between neonatologists and obstetricians: a survey study in China

Objectives

Neonatologists and obstetricians are crucial decision-makers regarding the resuscitation of extremely preterm infants (EPIs). However, there is a scarcity of research regarding the differing perspectives on EPI resuscitation between these medical professionals. We aim to determine the differences and influential factors of their attitudes towards EPIs resuscitation in China.

Methods

This cross-sectional study was conducted in public hospitals of 31 provinces in Chinese mainland from June to July 2021. Influential factors of binary variables and those of ordinal variables were analyzed by modified Poisson regression models and multinomial logistic regression models due to the invalid parallel line assumption of ordinal logistic regression models.

Results

A total of 832 neonatologists and 1,478 obstetricians who were deputy chief physicians or chief physicians participated. Compared with obstetricians, neonatologists delivered a larger proportion of infants of <28-week gestational age (87.74% vs. 84.91%) and were inclined to think it inappropriate to use 28 weeks as the cutoff of gestational age for providing full care to premature infants [63.34% vs. 31.60%, adjusted prevalence ratio = 1.61 (95% CI: 1.46-1.77)], and to suggest smaller cutoffs of gestational age and birth weight for providing EPIs resuscitation. Notably, 46.49% of the neonatologists and 19.01% of the obstetricians believed infants ≤24 weeks' gestation should receive resuscitation.

Conclusions

In China, notable disparities exist in attitudes of neonatologists and obstetricians towards resuscitating EPIs. Strengthening collaboration between these two groups and revising the pertinent guidelines as soon as possible would be instrumental in elevating the resuscitation rate of EPIs.

Ethical Dilemmas in Neonatal Care at the Limit of Viability

Advances in neonatal care have pushed the limit of viability to incrementally lower gestations over the last decades. However, surviving extremely premature neonates are prone to long-term neurodevelopmental handicaps. This makes ethics a crucial dimension of periviable birth management. At 22 weeks, survival ranges from 1 to 15%, and profound disabilities in survivors are common. Consequently, there is no beneficence-based obligation to offer any aggressive perinatal management. At 23 weeks, survival ranges from 8 to 54%, and survival without severe handicap ranges from 7 to 23%. If fetal indication for cesarean delivery appears, the procedure may be offered when neonatal resuscitation is planned. At a gestational age ≥24 weeks, up to 51% neonates are expected to survive the neonatal period. Survival without profound neurologic disability ranges from 12 to 38%. Beneficence-based obligation to intervene is reasonable at these gestations. Nevertheless, autonomy of parents should also be respected, and parental consent should be sought prior to any intervention. Optimal counselling of parents involves harmonized cooperation of obstetric and neonatal care providers. Every fetus/neonate and every pregnant woman are different and have the right to be considered individually when treatment decisions are being made.

Active approach in delivery room and survival of infants born between 22 and 26 gestational weeks are increasing in Spain

AIM

To describe the trends in the delivery room approach and survival of extremely premature infants over the past two decades.

METHODS

Time-series analysis of infants included in the Spanish SEN1500 network from 2004 to 2019. Patients born from 22 + 0 to 26 + 6 weeks were included. The primary outcome was an active approach in the delivery room. Survival and temporal trends were also studied.

RESULTS

The study population included 8284 patients. At 22 and 23 weeks, an active approach was followed in 41.4% and 80.8%. A temporal trend toward a more active approach was observed at 23 weeks. Antenatal steroids were administered in 19.6% and 58.1% at 22 and 23 weeks. From 24 weeks, an active approach was applied in nearly all cases throughout the period, and more than 80% of patients received antenatal steroids. The rates of survival after an active approach were 8.7%, 21.6%, 40.6%, 59.9%, and 74.7% at 22, 23, 24, 25, and 26 weeks and significantly increased over the period, except for infants born at 22 weeks.

CONCLUSION

Active management and survival of infants born from 23 weeks increased over the period, but the frequency of antenatal steroid administration was lower than the intention to resuscitate.

Gestational age-specific neonatal mortality in Hong Kong: a population-based retrospective study

BACKGROUND

The neonatal period is the most vulnerable period during childhood, with the risk of death being the highest even in developed countries/regions. Hong Kong's neonatal mortality (1‰) is among the world's lowest and has remained similar for 15 years. This study aimed to explore neonatal deaths in Hong Kong in detail and determine whether neonatal mortality is reducible at such a low level.

METHODS

Live births in public hospitals in Hong Kong during 01 Jan 2006-31 Dec 2017 were included. Relevant data were extracted from the electronic medical records. Gestational age-specific mortality was calculated, and the trends were analyzed using the Cochran-Armitage trend test. Causes of death were summarized, and risk factors were identified in multivariate logistic regression analysis.

RESULTS

In 490,034 live births, 755 cases (1.54‰) died during the neonatal period, and 293 (0.6‰) died during the post-neonatal period. The neonatal mortality remained similar overall (P = 0.17) and among infants born at 24-29 weeks' gestation (P = 0.4), while it decreased in those born at 23 (P = 0.04), 30-36 (P < 0.001) and ≥ 37 (P < 0.001) weeks' gestation. Neonates born at < 27 weeks' gestation accounted for a significantly increased proportion among cases who died (27.6% to 51.9%), with hemorrhagic conditions (24%) being the leading cause of death. Congenital anomalies were the leading cause of death in neonates born ≥ 27 weeks' gestation (52%), but its cause-specific mortality decreased (P = 0.002, 0.6‰ to 0.41‰), with most of the decrease attributed to trisomy 13/18 and multiple anomalies.

CONCLUSION

Reduction of neonatal mortality in developed regions may heavily rely on improved quality of perinatal and neonatal care among extremely preterm infants.

Attitudes About Extremely Preterm Birth Among Obstetric and Neonatal Health Care Professionals in England: A Qualitative Study

Importance

Variation in attitudes between health care professionals involved in the counseling of parents facing extremely preterm birth (<24 wk gestational age) may lead to parental confusion and professional misalignment.

Objective

To explore the attitudes of health care professionals involved in the counseling of parents facing preterm birth on the treatment of extremely preterm infants.

Design, Setting, and Participants

This qualitative study used Q methods to explore the attitudes of neonatal nurses, neonatologists, midwives, and obstetricians involved in the care of extremely preterm infants in 4 UK National Health Service perinatal centers between February 10, 2020, and April 30, 2021. Each participating center had a tertiary level neonatal unit and maternity center. Individuals volunteered participation through choosing to complete the study following a presentation by researchers at each center. A link to the online Q study was emailed to all potential participants by local principal investigators. Participants ranked 53 statements about the treatment of extremely preterm infants in an online quasi-normal distribution grid from strongly agree (6) to strongly disagree (-6).

Main Outcomes and Measures

Distinguishing factors per professional group (representing different attitudes) identified through by-person factor analysis of Q sort-data were the primary outcome. Areas of shared agreement (consensus) between professional groups were also explored. Q sorts achieving a factor loading of greater than 0.46 (P < .01) on a given factor were included.

Results

In total, 155 health care professionals volunteered participation (128 [82.6%] women; mean [SD] age, 41.6 [10.2] years, mean [SD] experience, 14.1 [9.6] years). Four distinguishing factors were identified between neonatal nurses, 3 for midwives, 5 for neonatologists, and 4 for obstetricians. Analysis of factors within and between professional groups highlighted significant variation in attitudes of professionals toward parental engagement in decision-making, the perceived importance of potential disability in decision-making, and the use of medical technology. Areas of consensus highlighted that most professionals disagreed with statements suggesting disability equates to reduced quality of life. The statement suggesting the parents' decision was considered the most important when considering neonatal resuscitation was placed in the neutral (middistribution) position by all professionals.

Conclusions and Relevance

The findings of this qualitative study suggest that parental counseling at extremely low gestations is a complex scenario further complicated by the differences in attitudes within and between professional disciplines toward treatment approaches. The development of multidisciplinary training encompassing all professional groups may facilitate a more consistent and individualized approach toward parental engagement in decision-making.

In the grey zone-survival and morbidities of periviable births

OBJECTIVE

To compare the survival and morbidities of infants born between 22 0/7-25 6/7 weeks of gestation.

STUDY DESIGN

This observational cohort study consisted of 187 eligible infants liveborn at a single, Level III Neonatal Intensive Care Unit (NICU) between June 1, 2009, and December 31, 2016, in Cleveland, Ohio. Infants with recognized syndromes or major congenital malformations were excluded from the review.

RESULT

The rate of survival to discharge for NICU-admitted infants born at 22- and 23- week was 56% and 54% respectively at our institution. There was no trend observed between gestational ages and incidence of necrotizing enterocolitis (NEC), patent ductus arteriousus (PDA), sepsis, or severe intraventricular hemorrhage (IVH- Grade 3 or 4). The infants born at 22 weeks had a higher incidence of retinopathy of prematurity (ROP) as compared to 25 weeks gestation (p < 0.001). The need for home oxygen was significantly higher in the smallest infants 70% at 22 weeks, 62% and 60% at 23 and 24 weeks versus 33% at 25 weeks gestation (p < 0.007). Those born at 22 weeks had the same rate of survival to discharge with severe IVH as those born at 23 weeks but required fewer VP shunts (p > 0.52).

CONCLUSIONS

The course of extremely preterm infants shows no difference between those born at 22 and 23 weeks of gestation in our NICU with regards to both mortality and short-term morbidities, although they differed marginally from 24 week gestation infants and significantly from those born at 25 weeks gestation.

Shifting Provider Attitudes and Institutional Resources Surrounding Resuscitation at the Limit of Gestational Viability

OBJECTIVE

This study aimed to provide contemporary data regarding provider perceptions of appropriate care for resuscitation and stabilization of periviable infants and institutional resources available to providers.

STUDY DESIGN

A Qualtrics survey was emailed to 672 practicing neonatologists in the United States by use of public databases. Participants were asked about appropriate delivery room care for infants born at 22 to 26 weeks gestational age, factors affecting decision-making, and resources utilized regarding resuscitation. Descriptive statistics were used to analyze the dataset.

RESULTS

In total, 180 responses were received, and 173 responses analyzed. Regarding preferred course of care based on gestational age, the proportion of respondents endorsing full resuscitation decreased with decreasing gestational age (25 weeks = 99%, 24 = 64%, 23 = 16%, and 22 = 4%). Deference to parental wishes correspondingly increased with decreasing gestational age (25 weeks = 1%, 24 = 35%, 23 = 82%, and 22 = 46%). Provision of comfort care was only endorsed at 22 to 23 weeks (23 weeks = 2%, 22 = 50%). Factors most impacting decision-making at 22 weeks gestational age included: outcomes based on population data (79%), parental wishes (65%), and quality of life measures (63%). Intubation with a 2.5-mm endotracheal tube (84%), surfactant administration in the delivery room (77%), and vascular access (69%) were the most supported therapies for initial stabilization. Availability of institutional resources varied; the most limited were obstetric support for cesarean delivery at the limit of viability (37%), 2.0-mm endotracheal tube (45%), small baby protocols (46%), and a consulting palliative care teams (54%).

CONCLUSION

There appears to be discordance in provider attitudes surrounding preferred actions at 23 and 22 weeks. Provider attitudes regarding decision-making at the limit of viability and identified resource limitations are nonuniform. Between-hospital variations in outcomes for periviable infants may be partly attributable to lack of provider consensus and nonuniform resource availability across institutions.

KEY POINTS

· Within the past decade, there has been a shift in the gray zone from 23-24 to 22-23 weeks gestation.. · Attitudes around resuscitation of infants are nonuniform despite perceived standardized approaches.. · Institutional variability in resources may contribute to variation in outcomes of periviable infants..

Decision making at extreme prematurity: Innovation in clinician education

Decision-making at extreme prematurity remains ethically and practically challenging and can result in parental and clinician distress. It is vital that clinicians learn the necessary skills integral to counseling and decision-making with families in these situations. A pedagogical approach to teaching counseling should incorporate adult learning theory, emphasize multidisciplinary team in-situ simulation that links to counseling clinicians' daily practice, and includes critical reflection, debriefing, and program assessment. Multiple educational strategies that train clinicians in advanced communication and decision-making offer promising results to optimize antenatal counseling and shared decision-making for families facing possible delivery at extreme prematurity. Continued process evaluation and innovation in these educational domains are needed while also assessing the effect on patient-centered outcomes.

Neonatal Outcome and Treatment Perspectives of Preterm Infants at the Border of Viability

Decision-making at the border of viability remains challenging for the expectant parents and the medical team. The preterm infant is dependent on others making the decision that will impact them for a lifetime in hopefully their best interest. Besides survival and survival without neurodevelopmental impairment, other relevant outcome measures, such as the quality of life of former preterm infants and the impact on family life, need to be integrated into prenatal counselling. Recommendations and national guidelines continue to rely on arbitrarily set gestational age limits at which treatment is not recommended, can be considered and it is recommended. These guidelines neglect other individual prognostic outcome factors like antenatal steroids, birth weight and gender. Besides individual factors, centre-specific factors like perinatal treatment intensity and the attitude of healthcare professionals significantly determine the futures of these infants at the border of viability. A more comprehensive approach regarding treatment recommendations and relevant outcome measures is necessary.

Ethical Cultures in Perinatal Care: Do They Exist? Correlation of Provider Attitudes with Periviability Practices at Six Centers

OBJECTIVE

This study aimed to compare attitudes of providers regarding perinatal management and outcomes for periviable newborns of caregivers at centers with higher resuscitation (HR) and lower resuscitation (LR) rates in the delivery room.

STUDY DESIGN

All obstetric and neonatal clinical providers at six U.S. sites were invited to complete an anonymous online survey. Survey responses were compared with clinical data collected from a previous retrospective study comparing centers' rates of planned resuscitation. Responses were analyzed by multivariable logistic and linear regression to assess how HR versus LR center respondents differed in management preferences and outcome predictions.

RESULTS

Paradoxically, HR versus LR respondents, when adjusting for other variables, were less likely to respond that interventions such as antenatal steroids (odds ratio: 0.61, 95% confidence interval [CI]: 0.42-0.88, p < 0.009) and resuscitation (OR: 0.59, 95% CI: 0.44-0.78, p < 0.001) should be given at 22 weeks. HR versus LR respondents also reported lower likelihood of survival and acceptable quality of life (OR: 0.7, 95% CI: 0.53-0.93, p = 0.012) at 23 weeks.

CONCLUSION

Despite higher rates of planned resuscitation at 22 and 23 weeks, steroid usage and survival rates did not differ between HR and LR sites. In this subsequent survey, respondents from HR centers had a less favorable outlook on interventions for these newborns than those at LR centers, suggesting that instead of driving practices, attitudes may be more closely associated with experiences of clinical outcomes.

Exploring implicit bias in the perceived consequences of prematurity amongst health care providers in North Queensland - a constructivist grounded theory study

Background

A study was done to explore the attitudes of relevant health care professionals (HCP) towards the provision of intensive care for periviable and extremely premature babies.

Methods/design

Applying a constructivist grounded theory methodology, HCP were interviewed about their attitudes towards the provision of resuscitation and intensive care for extremely premature babies. These babies are at increased risk of death and neurodisability when compared to babies of older gestations. Participants included HCP of varying disciplines at a large tertiary centre, a regional centre and a remote centre. Staff with a wide range of experience were interviewed.

Results

Six categories of i) who decides, ii) culture and context of families, iii) the life ahead, iv) to treat a bit or not at all, v) following guidelines and vi) information sharing, emerged. Role specific implicit bias was found as a theoretical construct, which depended on the period for which care was provided relative to the delivery of the baby. This implicit bias is an underlying cause for the negativity seen towards extreme prematurity and is presented in this paper. HCP caring for women prior to delivery have a bias towards healthy term babies that involves overestimation of the risks of extreme prematurity, while neonatal staff were biased towards suffering in the neonatal period and paediatricians recognise positivity of outcomes regardless of neurological status of the child. The implicit bias found may explain negativity towards intensive care of periviable neonates.

Conclusion

Understanding the presence and origins of role specific implicit bias may enable HCP to work together to improve care for parents preparing for the delivery of extremely premature babies.

Negativity about the outcomes of extreme prematurity a persistent problem - a survey of health care professionals across the North Queensland region

Background

Extremely preterm babies are at risk of significant mortality and morbidity due to their physiological immaturity. At periviable gestations decisions may be made to either provide resuscitation and intensive care or palliation based on assessment of the outlook for the baby and the parental preferences. Health care professionals (HCP) who counsel parents will influence decision making depending on their individual perceptions of the outcome for the baby. This paper aims to explore the knowledge and attitudes towards extremely preterm babies of HCP who care for women in pregnancy in a tertiary, regional and remote setting in North Queensland.

Methods

A cross sectional electronic survey of HCP was performed. Perceptions of survival, severe disability and intact survival data were collected for each gestational age from 22 to 27 completed weeks gestation. Free text comment enabled qualitative content analysis.

Results

Almost all 113 HCP participants were more pessimistic than the actual outcome data suggests. HCP caring for women antenatally were the most pessimistic for survival (p = 0.03 at 23 weeks, p = 0.02 at 25,26 and 27 weeks), severe disability (p = 0.01 at 24 weeks) and healthy outcomes (p = 0.01 at 24 weeks), whilst those working in regional and remote centres were more negative than those in tertiary unit for survival (p = 0.03 at 23,24,25 weeks). Perception became less negative as gestational age increased.

Conclusion

Pessimism of HCP may be negatively influencing decision making and will negatively affect the way in which parents perceive the chances of a healthy outcome for their offspring.

Lower gestational age is associated with severe maternal morbidity of preterm cesarean delivery

OBJECTIVE

To evaluate whether gestational age was associated with the severe maternal morbidity (SMM) of preterm cesarean delivery between 22 and 34 weeks of gestation (weeks).

MATERIAL AND METHODS

We performed an observational retrospective cohort study in two tertiary university hospitals in 2018. We included all mothers of preterm infants born by caesarean delivery between 22 and 34 weeks, excluding mothers with multiple births greater than two, with pregnancy terminations or stillbirths, and who died unrelated to obstetrical causes. The principal endpoint, SMM, was a composite outcome (classical uterine incision, postpartum hemorrhage defined by blood loss ≥ 500 mL, blood transfusion, any injury to adjacent organs, unplanned procedure/need for reintervention, Intensive Care Unit (ICU) stay longer than 24 h, postpartum fever, and/or death).

RESULTS

Among the 252 women, SMM occurred in 89 (35.3 %) cases. After multivariate analysis, gestational age was independently associated with SMM (adjusted Odds Ratio [aOR] 0.87; 95 % Confidence Interval [CI] 0.78-0.97). The other variables statistically associated with SMM were type of pregnancy with a negative association with twin pregnancy (aOR, 0.44; 95 % CI, 0.20-0.93) and a positive association with general anesthesia (aOR, 2.52; 95 % CI, 1.25-5.13). A sensitivity analysis was performed and found an association, at the limit of significance, between gestational age < 28 weeks and SMM (aOR, 1.80; 95 % CI, 0.99-3.27, p = 0.05).

CONCLUSION

Lower gestational age was associated with the risk of SMM for preterm caesarean delivery between 22 and 34 weeks. Obstetricians should integrate this knowledge into their shared decision-making processes with parents.

Effect of written outcome information on attitude of perinatal healthcare professionals at the limit of viability: a randomized study

Background

Differences in perception and potential disagreements between parents and professionals regarding the attitude for resuscitation at the limit of viability are common. This study evaluated in healthcare professionals whether the decision to resuscitate at the limit of viability (intensive care versus comfort care) are influenced by the way information on incurred risks is given or received.

Methods

This is a prospective randomized controlled study. This study evaluated the attitude of healthcare professionals by testing the effect of information given through graphic fact sheets formulated either optimistically or pessimistically. The written educational fact sheet included three graphical presentations of survival and complication/morbidity by gestational age. The questionnaire was submitted over a period of 4 months to 5 and 6-year medical students from the Geneva University as well as physicians and nurses of the neonatal unit at the University Hospitals of Geneva. Our sample included 102 healthcare professionals.

Results

Forty-nine responders (48%) were students (response rate of 33.1%), 32 (31%) paediatricians (response rate of 91.4%) and 21 (20%) nurses in NICU (response rate of 50%). The received risk tended to be more severe in both groups compared to the graphically presented facts and current guidelines, although optimistic representation favoured the perception of “survival without disability” at 23 to 25 weeks. Therapeutic attitudes did not differ between groups, but healthcare professionals with children were more restrained and students more aggressive at very low gestational ages.

Conclusion

Written information on mortality and morbidity given to healthcare professionals in graphic form encourages them to overestimate the risk. However, perception in healthcare staff may not be directly transferable to parental perception during counselling as the later are usually naïve to the data received. This parental information are always communicated in ways that subtly shape the decisions that follow.

Neonatal Outcomes in Extremely Preterm Newborns Admitted to Intensive Care after No Active Antenatal Management: A Population-Based Cohort Study

OBJECTIVE

To evaluate the association between active antenatal management and neonatal outcomes in extremely preterm newborns admitted to a neonatal intensive care unit (NICU).

STUDY DESIGN

This population-based cohort study was conducted in 25 regions of France. Infants born in 2011 between 22^0/7 and 26^6/7 weeks of gestation and admitted to a NICU were included. Infants with lethal congenital malformations or death in the delivery room were excluded. A multilevel multivariable analysis was performed, accounting for clustering by mother (multiple pregnancies) and hospital plus individual characteristics, to estimate the association between the main exposure of no active antenatal management (not receiving antenatal corticosteroids, magnesium sulfate, or cesarean delivery for fetal indications) and a composite outcome of death or severe neonatal morbidity (including severe forms of brain or lung injury, retinopathy of prematurity, and necrotizing enterocolitis).

RESULTS

Among 3046 extremely preterm births, 783 infants were admitted to a NICU. Of these, 138 (18%) did not receive active antenatal management. The risk of death or severe morbidity was significantly higher for infants without active antenatal management (crude OR, 2.60; 95% CI, 1.44-4.66). This finding persisted after adjustment for gestational age (OR, 2.08; 95% CI, 1.19-3.62) and all confounding factors (OR, 1.86; 95% CI, 1.09-3.20).

CONCLUSIONS

The increased risk of severe neonatal outcomes for extremely preterm babies admitted to a NICU without optimal antenatal management should be considered in individual-level decision making and in the development of professional guidelines for the management of extremely preterm births.

Providing active antenatal care depends on the place of birth for extremely preterm births: the EPIPAGE 2 cohort study

Survival rates of infants born before 25 weeks of gestation are low in France and have not improved over the past decade. Active perinatal care increases these infants' likelihood of survival.

OBJECTIVE

Our aim was to identify factors associated with active antenatal care, which is the first step of proactive perinatal care in extremely preterm births.

METHODS

The population included 1020 singleton births between 22^0/6 and 26^0/6 weeks of gestation enrolled in the Etude Epidémiologique sur les Petits Ages Gestationnels 2 study, a French national population-based cohort of very preterm infants born in 2011. The main outcome was 'active antenatal care' defined as the administration of either corticosteroids or magnesium sulfate or delivery by caesarean section for fetal rescue. A multivariable analysis was performed using a two-level multilevel model taking into account the maternity unit of delivery to estimate the adjusted ORs (aORs) of receiving active antenatal care associated with maternal, obstetric and place of birth characteristics.

RESULTS

Among the population of extremely preterm births, 42% received active antenatal care. After standardisation for gestational age, regional rates of active antenatal care varied between 22% (95% CI 5% to 38%) and 61% (95% CI 44% to 78%). Despite adjustment for individual and organisational characteristics, active antenatal care varied significantly between maternity units (p=0.03). Rates of active antenatal care increased with gestational age with an aOR of 6.46 (95% CI 3.40 to 12.27) and 10.09 (95% CI 5.26 to 19.36) for infants born at 25 and 26 weeks' gestation compared with those born at 24 weeks. No other individual characteristic was associated with active antenatal care.

CONCLUSION

Even after standardisation for gestational age, active antenatal care in France for extremely preterm births varies widely with place of birth. The dependence of life and death decisions on place of birth raises serious ethical questions.

Variation in quality report viewing by providers and correlation with NICU quality metrics

BACKGROUND

To examine variation in quality report viewing and assess correlation between provider report viewing and neonatal intensive care unit (NICU) quality.

METHODS

Variation in report viewing sessions for 129 California Perinatal Quality Care Collaborative NICUs was examined. NICUs were stratified into tertiles based on their antenatal steroid (ANS) use and hospital-acquired infection (HAI) rates to compare report viewing session counts.

RESULTS

The number of report viewing sessions initiated by providers varied widely over a 2-year period (median=11; mean=25.5; s.d.=45.19 sessions). Report viewing was not associated with differences in ANS use. Facilities with low HAI rates had less frequent report viewing. Facilities with high report views had significant improvements in HAI rates over time.

CONCLUSIONS

Available audit and feedback reports are utilized inconsistently across California NICUs despite evidence that report viewing is associated with improvements in quality of care delivery. Further studies are needed for reports to reach their theoretical potential.

Survival of Infants Born at Periviable Gestational Ages

Periviable births are those occurring from 20 0/7 through 25 6/7 weeks of gestation. Among and within developed nations, significant variation exists in the approach to obstetric and neonatal care for periviable birth. Understanding gestational age-specific survival, including factors that may influence survival estimates and how these estimates have changed over time, may guide approaches to the care of periviable births and inform conversations with families and caregivers. This review provides a historical perspective on survival following periviable birth, summarizes recent and new data on gestational age-specific survival rates, and addresses factors that have a significant impact on survival.

Changes in management policies for extremely preterm births and neonatal outcomes from 2003 to 2012: two population-based studies in ten European regions

OBJECTIVE

To investigate changes in maternity and neonatal unit policies towards extremely preterm infants (EPTIs) between 2003 and 2012, and concurrent trends in their mortality and morbidity in ten European regions.

DESIGN

Population-based cohort studies in 2003 (MOSAIC study) and 2011/2012 (EPICE study) and questionnaires from hospitals.

SETTING

70 hospitals in ten European regions.

POPULATION

Infants born at <27 weeks of gestational age (GA) in hospitals participating in both the MOSAIC and EPICE studies (1240 in 2003, 1293 in 2011/2012).

METHODS

We used McNemar's Chi² test, paired t-tests and conditional logistic regression for comparisons over time.

MAIN OUTCOMES MEASURES

Reported policies, mortality and morbidity of EPTIs.

RESULTS

The lowest GA at which maternity units reported performing a caesarean section for acute distress of a singleton non-malformed fetus decreased from an average of 24.7 to 24.1 weeks (P < 0.01) when parents were in favour of active management, and 26.1 to 25.2 weeks (P = 0.01) when parents were against. Units reported that neonatologists were called more often for spontaneous deliveries starting at 22 weeks GA in 2012 and more often made decisions about active resuscitation alone, rather than in multidisciplinary teams. In-hospital mortality after live birth for EPTIs decreased from 50% to 42% (P < 0.01). Units reporting more active management in 2012 than 2003 had higher mortality in 2003 (55% versus 43%; P < 0.01) and experienced larger declines (55 to 44%; P < 0.001) than units where policies stayed the same (43 to 37%; P = 0.1).

CONCLUSIONS

European hospitals reporting changes in management policies experienced larger survival gains for EPTIs.

TWEETABLE ABSTRACT

Changes in reported policies for management of extremely preterm births were related to mortality declines.

Opinions of paediatricians who teach neonatal resuscitation about resuscitation practices on extremely preterm infants in the delivery room

OBJECTIVE

To describe the opinions of paediatricians who teach resuscitation in Brazil regarding resuscitation practices in the delivery room (DR) of preterm infants with gestational ages of 23-26 weeks.

METHODS

Cross-sectional study with an internationally validated electronic questionnaire (December 2011-September 2013) sent to the instructors of the Neonatal Resuscitation Program of the Brazilian Society of Paediatrics on parental counselling practices, medical limits for resuscitation of extremely preterm infants and medical considerations for decision-making in this group of infants. The analysis was descriptive.

RESULTS

Among 685 instructors, 560 (82%) agreed to participate. Only 5%-13% reported having opportunity for antenatal counselling parents: if called, 22% reported discussing with the family about the possibility not to resuscitate in the DR; 63% about the possibility of death in the DR and 89% about the possibility of death in the neonatal unit. If the parents did not agree with the advice of the paediatrician, 30%-50% of the respondents would follow the procedures they advised regardless of the opinion of the parents. The higher the gestational age, the lower is the percentage of paediatricians who believed that parents should participate in decision-making. Only 9% participants reported the existence of written guidelines at their hospital on initiation of resuscitation in the DR at limits of viability, but 80% paediatricians reported using some criteria for limiting resuscitation in the DR.

CONCLUSION

The picture obtained in this study of Brazilian paediatricians indicates that resuscitation of extremely preterm infants is permeated by ambivalence and contradictions.

Practices and education surrounding anticipated periviable deliveries among neonatal-perinatal medicine and maternal-fetal medicine fellowship programs

OBJECTIVES

To explore national practices of periviable decision-making and care, and to determine and compare trainee education in this domain, within neonatal-perinatal medicine (NPP) and maternal-fetal medicine (MFMP) fellowship programs.

STUDY DESIGN

A 75-item survey was sent to NPP and MFMP program directors in the United States.

RESULTS

In all, 79 of 168 surveys were completed (47%). MFMPs reported offering active interventions for bigger or more mature fetuses (versus NPPs). Variability exists in estimated frequency of simultaneous antenatal counseling by both specialties (range 0 to 90%) and of inter-specialty communication before consultation (range 5 to 100%). One-quarter of MFMPs reported no fellow education regarding periviable deliveries, versus 2% of NPPs (P=0.002); 40% of MFMPs teach fellows about periviable ethics, versus 63% of NPPs (P=0.05). NPPs more frequently utilize role modeling (P=0.01) and simulation (P=0.01) as learning methods.

CONCLUSION

NPPs and MFMPs report different, often asynchronous, practices and fellow education regarding antenatal counseling and resuscitation at periviability.

A Proactive Approach to Neonates Born at 23 Weeks of Gestation

OBJECTIVE

To evaluate in-hospital survival, survival without major morbidity, and neurodevelopmental impairment for neonates born at 23 weeks of gestation provided proactive, coordinated, and comprehensive perinatal and neonatal management.

METHODS

This was a retrospective cohort study conducted at a single, tertiary care center between 2004 and 2013. Enrollment was limited to mother-neonate dyads at 23 weeks of gestation who were provided a proactive approach defined as documented evidence of antenatal corticosteroid administration, willingness to provide cesarean delivery for fetal distress, and neonatal resuscitation and intensive care. Among survivors, major morbidities (predischarge) and neurodevelopmental assessments at corrected ages of 18-22 months were examined.

RESULTS

Among 152 live births identified, 101 neonates received proactive care, of whom 60 (59%) survived to hospital discharge. Preterm premature rupture of membranes (adjusted odds ratio [OR] 0.29, 95% confidence interval [CI] 0.09-0.94), fetal growth restriction (OR 0.16, 95% CI 0.03-0.89), delivery room cardiopulmonary resuscitation (OR 0.07, 95% CI 0.02-0.32), and prolonged intubation sequence (OR 0.15, 95% CI 0.05-0.45) were associated with lower neonatal survival. Among neonatal intensive care unit survivors, 62% had at least one major morbidity. Among 50 survivors with assessment at 18-22 months, six (12%) were unimpaired, 20 (40%) had mild impairment, and 24 (48%) had moderate or severe neurodevelopmental impairment.

CONCLUSION

Proactive, interdisciplinary care enabled more than half of the neonates born at 23 weeks of gestation to survive, and approximately half of children evaluated at 18 months exhibited no or mild impairment. This information should be considered when providing prognostic advice to families with threatened preterm birth at 23 weeks of gestation.

Factors influencing the care provided for periviable babies in Australia: a narrative review

Survival at extreme prematurity is becoming increasingly common. Neurodisability is an increasing risk with decreasing gestation. This review outlines the risks of extreme prematurity and the attitudes of health care providers and families in Australia of periviable babies. High quality data is difficult to find due to differing definitions and methods of assessment of disability. Meta-analyses of outcomes of prematurity published from 2008 to 2013, including babies born from 1990 onwards, suggest a severe disability rate of around 20 % at 22 to 26 weeks completed gestation, with moderate disability decreasing with increasing gestation. Studies show that Australian health care providers underestimate the survival and positive outcomes of these babies. The majority of Australian health care providers state that parental preference would determine the decision to offer care to babies at 23 weeks gestation, however, all had a threshold above which parental preference would be ignored in favour of resuscitation .This ranged from 22 to 27 completed weeks gestation. The few studies examining Australian parental involvement in resuscitation decisions, showed that the majority of parents felt that health professionals alone had made the decision to resuscitate their extremely preterm babies and the parents themselves did not wish to be the primary decision makers in withholding care. The babies progressed better than parents had expected following antenatal counselling. The attitudes of health care providers, experiences and opinions of parents seem to be at odds with the current move to increase parental decision making at the most extremes of gestation. Current Australian guidelines suggest parental decision making below 25 weeks gestation, and primarily clinician decision making over this gestation. The increased risks of prematurity and adverse outcomes for the North Queensland population is also explored. This population has a high proportion of Aboriginal and Torres Strait Islanders who have increased risks which are primarily linked to poor socioeconomic factors and are highest for the most remote residents. Attitudes towards delivery of care to these highest risk babies from health professionals and in the populations themselves have not been studied.

Trends in Care Practices, Morbidity, and Mortality of Extremely Preterm Neonates, 1993-2012

IMPORTANCE

Extremely preterm infants contribute disproportionately to neonatal morbidity and mortality.

OBJECTIVE

To review 20-year trends in maternal/neonatal care, complications, and mortality among extremely preterm infants born at Neonatal Research Network centers.

DESIGN, SETTING, PARTICIPANTS

Prospective registry of 34,636 infants, 22 to 28 weeks' gestation, birth weight of 401 to 1500 g, and born at 26 network centers between 1993 and 2012.

EXPOSURES

Extremely preterm birth.

MAIN OUTCOMES AND MEASURES

Maternal/neonatal care, morbidities, and survival. Major morbidities, reported for infants who survived more than 12 hours, were severe necrotizing enterocolitis, infection, bronchopulmonary dysplasia, severe intracranial hemorrhage, cystic periventricular leukomalacia, and/or severe retinopathy of prematurity. Regression models assessed yearly changes and were adjusted for study center, race/ethnicity, gestational age, birth weight for gestational age, and sex.

RESULTS

Use of antenatal corticosteroids increased from 1993 to 2012 (24% [348 of 1431 infants]) to 87% (1674 of 1919 infants]; P < .001), as did cesarean delivery (44% [625 of 1431 births] to 64% [1227 of 1921]; P < .001). Delivery room intubation decreased from 80% (1144 of 1433 infants) in 1993 to 65% (1253 of 1922) in 2012 (P < .001). After increasing in the 1990s, postnatal steroid use declined to 8% (141 of 1757 infants) in 2004 (P < .001), with no significant change thereafter. Although most infants were ventilated, continuous positive airway pressure without ventilation increased from 7% (120 of 1666 infants) in 2002 to 11% (190 of 1756 infants) in 2012 (P < .001). Despite no improvement from 1993 to 2004, rates of late-onset sepsis declined between 2005 and 2012 for infants of each gestational age (median, 26 weeks [37% {109 of 296} to 27% {85 of 320}]; adjusted relative risk [RR], 0.93 [95% CI, 0.92-0.94]). Rates of other morbidities declined, but bronchopulmonary dysplasia increased between 2009 and 2012 for infants at 26 to 27 weeks' gestation (26 weeks, 50% [130 of 258] to 55% [164 of 297]; P < .001). Survival increased between 2009 and 2012 for infants at 23 weeks' gestation (27% [41 of 152] to 33% [50 of 150]; adjusted RR, 1.09 [95% CI, 1.05-1.14]) and 24 weeks (63% [156 of 248] to 65% [174 of 269]; adjusted RR, 1.05 [95% CI, 1.03-1.07]), with smaller relative increases for infants at 25 and 27 weeks' gestation, and no change for infants at 22, 26, and 28 weeks' gestation. Survival without major morbidity increased approximately 2% per year for infants at 25 to 28 weeks' gestation, with no change for infants at 22 to 24 weeks' gestation.

CONCLUSIONS AND RELEVANCE

Among extremely preterm infants born at US academic centers over the last 20 years, changes in maternal and infant care practices and modest reductions in several morbidities were observed, although bronchopulmonary dysplasia increased. Survival increased most markedly for infants born at 23 and 24 weeks' gestation and survival without major morbidity increased for infants aged 25 to 28 weeks. These findings may be valuable in counseling families and developing novel interventions.

First- and fifth-minute Apgar scores of 0-3 and infant mortality: a population-based study in São Paulo State of Brazil

AIMS

To determine the infant mortality of newborns with 1- and 5-min Apgar scores of 0-3.

RESULTS

Population cohort study with neonates with birth weight ≥400 g, gestational age ≥22 weeks and 1- and 5-min Apgar scores of 0-3, without malformations, born in São Paulo State (Brazil) from January 2006 to December 2007. Apgar scores were confirmed in the original certificates of live births and/or medical records. During this period, among 1,027,132 live births, 1640 met the study criteria, with an incidence of 1.6 per 1000 live births. When the 5-min Apgar score was 0, 1, 2 and 3, the infant mortality rate was 97%, 94%, 64% and 47%, respectively. Risk factors associated with infant deaths were 5-min Apgar score of 0 or 1 [odds ratio (OR) 16.6, 95% confidence interval (CI) 11.1-24.8], birth weight <2500 g (OR 7.5, 95% CI 5.7-9.8), birth at hospitals outside the state capital (OR 1.7, 95% CI 1.3-2.3), in private or charitable hospitals (OR 1.6, 95% CI 1.2-2.0), and during the night shift (OR 1.3, 95% CI 1.0-1.7).

CONCLUSIONS

For infants with 1- and 5-min Apgar scores of 0-3, the infant mortality is high. Besides the biological variables associated with the chance of dying, the organization of the perinatal care influences the outcome.

Antenatal Counseling Regarding Resuscitation and Intensive Care Before 25 Weeks of Gestation

The anticipated birth of an extremely low gestational age (,25 weeks) infant presents many difficult questions, and variations in practice continue to exist.Decisions regarding care of periviable infants should ideally be well informed,ethically sound, consistent within medical teams, and consonant with the parents' wishes. Each health care institution should consider having policies and procedures for antenatal counseling in these situations. Family counseling may be aided by the use of visual materials, which should take into consideration the intellectual, cultural, and other characteristics of the family members. Although general recommendations can guide practice, each situation is unique; thus, decision-making should be individualized. In most cases, the approach should be shared decision-making with the family, guided by considering both the likelihood of death or morbidity and the parents' desires for their unborn child. If a decision is made not to resuscitate,providing comfort care, encouraging family bonding, and palliative care support are appropriate.

Perspectives on anticipated quality-of-life and recommendations for neonatal intensive care: a survey of neonatal providers

OBJECTIVE

Explore associations between neonatal providers' perspectives on survival, quality of life (QOL) and treatment recommendations.

METHODS

Providers attending a workshop on neonatal viability were surveyed about survival, perceived QOL and treatment recommendations for marginally viable infants. We assessed associations between estimated survival and perceived QOL and treatment recommendations.

RESULTS

In the 44 included surveys, estimates of survival and QOL varied widely. Maximum care was recommended 80% of the time when anticipated QOL was high, versus 20% when anticipated QOL was low (p < 0.001). Adjusted for confounders, odds of recommending maximum intervention were 4.4 times higher when anticipated QOL was high (95% CI 1.9 - 10.2, p = 0.001).

CONCLUSIONS

The perspectives of practitioners who provide care to critically ill neonates regarding potential survival and QOL vary dramatically and are associated with the treatments those practitioners recommend. Practitioners should take care to avoid basing treatment recommendations on their own perspectives if they are not well aligned with those of the parents.

[Peri-viability: limits of prematurity in a regional hospital in the last 10 years]

AIM

To determine the preterm viability between 22 and 25 gestational weeks in our hospital in last 10 years.

PATIENTS AND METHODS

A descriptive retrospective study was conducted on preterms between 22-25 gestational weeks born between 1-1-2002 and 12-31-2011.

RESULTS

There were 121 newborns, 45 (37%) stillbirths and 76 (63%) live births (16 died in delivery room, and 60 admitted to neonatal intensive unit). Among the 60 admitted, 34 died before hospital discharge, and 26 survived (21% of total, 34% of live births and 43% of those admitted to neonatal intensive unit). The causes of death were: 16 therapeutic effort limitation in delivery room, 8 therapeutic effort limitation in neonatal ward, 7 nosocomial sepsis, 7 NEC, 4 respiratory problems, and 8 of unknown cause. There were no survivors below 24 gestational weeks. Of the 26 survivors, 4 had major neurological disorders, and 11 with a normal neurological outcome. No significant statistical differences were found in the mortality between the two five-year periods analysed.

CONCLUSIONS

The peri-viability has important clinical and ethical problems for neonatologist.
