Antenatal Periviability Counseling and Decision Making: A Retrospective Examination by the Investigating Neonatal Decisions for Extremely Early Deliveries Study Group

Factors Associated with Receiving No Maternal or Neonatal Interventions among Periviable Deliveries

OBJECTIVE

 The aim of this study was to quantify the influence of maternal sociodemographic, medical, and pregnancy characteristics on not receiving maternal and neonatal interventions with deliveries occurring at 22 to 23 weeks of gestation.

STUDY DESIGN

 This was a case-control study of U.S. live births at 220/6 to 236/7 weeks of gestation using vital statistics birth records from 2012 to 2016. We analyzed births that received no interventions for periviable delivery. Births were defined as having no interventions if they did not receive maternal (cesarean delivery, maternal hospital transfer, or antenatal corticosteroid administration) or neonatal interventions (neonatal intensive care unit admission, surfactant administration, antibiotic administration, or assisted ventilation). Logistic regression estimated the influence of maternal and pregnancy factors on the receipt of no interventions when delivery occurred at 22 to 23 weeks.

RESULTS

 Of 19,844,580 U.S. live births in 2012-2016, 24,379 (0.12%) occurred at 22 to 23 weeks; 54.3% of 22-week deliveries and 15.7% of 23-week deliveries received no interventions. Non-Hispanic Black maternal race was associated with no maternal interventions at 22 and 23 weeks. Private insurance, singleton pregnancy, and small for gestational age were associated with receiving no neonatal interventions at 22 and 23 weeks of gestation.

CONCLUSION

 Withholding or refusing maternal and neonatal interventions occurs frequently at the threshold of viability. Our data highlight various sociodemographic, pregnancy, and medical factors associated with decisions to not offer or receive maternal or neonatal interventions when birth occurs at the threshold of viability. The data elucidate observed practices and may assist in the development of further research.

KEY POINTS

· Non-Hispanic Black race was associated with receiving no maternal interventions.. · Indicators of high socioeconomic status were associated with no neonatal inventions.. · Patient-level factors influence the receipt of no interventions for periviable birth..

How do Clinicians View the Process of Shared Decision-Making with Parents Facing Extremely Early Deliveries? Results from an Online Survey

OBJECTIVE

 The objective of this study was to better understand how neonatology (Neo) and maternal-fetal medicine (MFM) physicians approach the process of shared decision-making (SDM) with parents facing extremely premature (<25 weeks estimated gestational age) delivery during antenatal counseling.

STUDY DESIGN

 Attending physicians at U.S. centers with both Neo and MFM fellowships were invited to answer an original online survey about antenatal counseling for extremely early newborns. Preferences for conveying information are reported elsewhere. Here, we report clinicians' self-assessments of their ability to engage in deliberations and decision-making and perceptions of what is important to parents in the SDM process. Multivariable logistic regression analyzed respondents' views with respect to individual characteristics, such as specialty, gender, and years of clinical experience.

RESULTS

 In total, 74 MFMs and 167 Neos representing 94% of the 81 centers surveyed responded. Neos versus MFMs reported repeat visits with parents less often (<0.001) and agreed that parents were more likely to have made delivery room decisions before they counseled them less often (p < 0.001). Respondents reported regularly achieving most goals of SDM, with the exception of providing spiritual support. Most respondents reported that spiritual and religious views, risk to an infant's survival, and the infant's quality of life were important to parental decision-making, while a physician's own personal choice and family political views were reported as less important. While many barriers to SDM exist, respondents rated language barriers and family views that differ from those of a provider as the most difficult barriers to overcome.

CONCLUSION

 This study provides insights into how consultants from different specialties and demographic groups facilitate SDM, thereby informing future efforts for improving counseling and engaging in SDM with parents facing extremely early deliveries and supporting evidence-based training for these complex communication skills.

KEY POINTS

· Perceptions differed by specialty and demographics.. · Parents' spiritual needs were infrequently met.. · Barriers to shared decision-making exist..

Association Between Periviable Delivery and New Onset of or Exacerbation of Existing Mental Health Disorders

OBJECTIVE

To evaluate whether there is an association between periviable delivery and new onset of or exacerbation of existing mental health disorders within 12 months postpartum.

METHODS

We conducted a retrospective cohort study of individuals with liveborn singleton neonates delivered at 22 or more weeks of gestation from 2008 to 2017 in the MarketScan Commercial Research Database. The exposure was periviable delivery , defined as delivery from 22 0/7 through 25 6/7 weeks of gestation. The primary outcome was a mental health morbidity composite of one or more of the following: emergency department encounter associated with depression, anxiety, psychosis, posttraumatic stress disorder, adjustment disorder, self-harm, or suicide; new psychotropic medication prescription; new behavioral therapy visit; and inpatient psychiatry admission in the 12 months postdelivery. Secondary outcomes included components of the primary composite. Those with and without periviable delivery were compared using multivariable logistic regression adjusted for clinically relevant covariates, with results reported as adjusted incident rate ratios (aIRRs). Effect modification by history of mental health diagnoses was assessed. Incidence of the primary outcome by 90-day intervals postdelivery was assessed.

RESULTS

Of 2,300,244 included deliveries, 16,275 (0.7%) were periviable. Individuals with periviable delivery were more likely to have a chronic health condition, to have undergone cesarean delivery, and to have experienced severe maternal morbidity. Periviable delivery was associated with a modestly increased risk of the primary composite outcome, occurring in 13.8% of individuals with periviable delivery and 11.0% of individuals without periviable delivery (aIRR 1.18, 95% CI 1.12-1.24). The highest-risk period for the composite primary outcome was the first 90 days in those with periviable delivery compared with those without periviable delivery (51.6% vs 42.4%; incident rate ratio 1.56, 95% CI 1.47-1.66).

CONCLUSION

Periviable delivery was associated with a modestly increased risk of mental health morbidity in the 12 months postpartum.

Assessing shared decision making during antenatal consultations regarding extreme prematurity

OBJECTIVE

To assess whether antenatal decisions regarding the neonatal care at birth for extremely preterm infants are more likely to be made when using shared decision-making (SDM)-style consultations compared to standard consultations.

STUDY DESIGN

In 2015, we implemented a clinical practice guideline promoting SDM use within antenatal consultations in our single-centre university-based perinatal unit. We conducted a prospective cohort study with a retrospective chart review based on data collected from all pregnant women presenting to obstetrical triage between 22 + 0 and 25 + 6 weeks gestation between September 2015 and June 2018.

RESULT

Two-hundred-and-seventeen cases presented; 137 received antenatal consultations with 82 (60%) being SDM-style. Decisions were frequently made (88%; 120/137) after the consultations, with no significant difference between consultation style (RR 1.08, 95% CI [0.95-1.26], p = 0.28).

CONCLUSION

The provision of either an SDM-style or a standard antenatal consultation seemed to comparably facilitate the reaching of a care decision.

Addressing bias and disparities in periviable counseling and care

Addressing bias and disparities in counseling and care requires that we contend with dehumanizing attitudes, stereotypes, and beliefs that our society and profession holds towards people of color, broadly, and Black birthing people in particular. It also necessitates an accounting of the historically informed, racist ideologies that shape present-day implicit biases. These biases operate in a distinctly complex and damaging manner in the context of end-of-life care, which centers around questions related to human pain, suffering, and value. Therefore, this paper aims to trace biases and disparities that operate in periviable care, where end-of-life decisions are made at the very beginning of life. We start from a historical context to situate racist ideologies into present day stereotypes and tropes that dehumanize and disadvantage Black birthing people and Black neonates in perinatal care. Here, we review the literature, address historical incidents and consider their impact on our ability to deliver patient-centered periviable care.

Prognostic value of clinicians' predictions of neonatal outcomes in counseling at the margin of gestational viability

Within antenatal counseling sessions at the margin of gestational viability, clinicians frequently to use population-based outcome data and statistical models to guide the decision-making process. These tools often utilize non-modifiable prenatal factors to estimate outcomes based on population averages. However, most parents prefer individualized predictions, which cannot be supported by these models. Additionally, prognostic accuracy is limited by institutional practices surrounding active management of infants at the margin of viability. Throughout the literature, parental perspectives emphasize the importance of communicating subjective information, such as providing hope and supporting personal values, over the importance of accurate prognostic information from the clinician. In this review we aim to describe the value of clinician prognoses in the decision-making process at the margin of gestational viability and emphasize the importance of addressing parental values during the counseling process, regardless of the expected outcome.

Perspectives on Resuscitation Decisions at the Margin of Viability among Specialist Newborn Care Providers in Ghana and Ethiopia: A Qualitative Analysis

Background

In high income countries, guidelines exist recommending gestational age thresholds for offering and obligating neonatal resuscitation for extremely preterm infants. In low- and middle- income countries, this approach may be impractical due to limited/inconsistent resource availability and challenges in gestational dating. Scant literature exists on how clinicians in these settings conceptualize viability or make resuscitation decisions for premature infants.

Methods

Qualitative interviews of interprofessional neonatal clinicians were conducted in Kumasi, Ghana, at Komfo Anokye Teaching Hospital and Suntreso Government Hospital, and in Addis Ababa, Ethiopia, at St. Paul’s Hospital Millennium Medical College. Transcribed interviews were coded through the constant comparative method.

Results

Three discrete major themes were identified. The principal theme was a respect for all life, regardless of the likelihood for survival. This sense of duty arose from a duty to God, a duty to the patient, and a duty intrinsic to one’s role as a medical provider. The duty to resuscitate was balanced by the second major theme, an acceptance of futility for many premature infants. Lack of resources, inappropriate staffing, and historically high local neonatal mortality rates were often described. The third theme was a desire to meet global standards of newborn care, including having resources to adopt the 22–25-week thresholds used in high income countries and being able to consistently provide life-saving measures to premature infants.

Conclusions

Neonatal clinicians in Ghana and Ethiopia described respect for all life and desire to meet global standards of newborn care, balanced with an awareness of futility based on local resource limitations. In both countries, clinicians highlighted how wide variations in regional survival outcomes limited their ability to rely on structured resuscitation guidelines based on gestational age and/or birthweight.

What Information Do Clinicians Deem Important for Counseling Parents Facing Extremely Early Deliveries?: Results from an Online Survey

OBJECTIVE

 The study aimed to better understand how neonatology and maternal fetal medicine (MFM) physicians convey information during antenatal counseling that requires facilitating shared decision-making with parents facing options of resuscitation versus comfort care after extremely early delivery STUDY DESIGN:  Attending physicians at US centers with both Neo and MFM fellowships were invited to answer an original online survey about antenatal counseling for extremely early newborns. The survey assessed information conveyed, processes for facilitating shared decision-making (reported separately), and clinical experiences. Neonatology and MFM responses were compared. Multivariable logistic regression analyzed topics often and seldom discussed by specialty groups with respect to respondents' clinical experience and resuscitation option preferences at different gestational weeks.

RESULTS

 In total, 74 MFM and 167 neonatologists representing 94% of the 81 centers surveyed responded. Grouped by specialty, respondents were similar in counseling experience and distribution of allowing choices between resuscitation and no resuscitation for delivery at specific weeks of gestational ages. MFM versus neonatology reported similar rates of discussing long-term health and developmental concerns and differed in all other categories of topics. Neonatologists were less likely than MFM to discuss caregiver impacts (odds ratio [OR]: 0.14, 95% confidence interval [CI]: 0.11-0.18, p < 0.001) and comfort care details (OR: 0.19, 95% CI: 0.15-0.25, p < 0.001). Conversely, neonatology versus MFM respondents more frequently reported "usually" discussing topics pertaining to parenting in the NICU (OR: 1.5, 95% CI: 1.2-1.8, p < 0.001) and those regarding stabilizing interventions in the delivery room (OR: 1.8, 95% CI: 1.4-2.2, p < 0.001). Compared with less-experienced respondents, those with 17 years' or more of clinical experience had greater likelihood in both specialties to say they "usually" discussed otherwise infrequently reported topics pertaining to caregiver impacts.

CONCLUSION

 Parents require information to make difficult decisions for their extremely early newborns. Our findings endorse the value of co-consultation by MFM and neonatology clinicians and of trainee education on antenatal consultation education to support these families.

KEY POINTS

· Neonatology versus MFM counselors provide complementary information.. · More experience was linked to discussing some topics.. · Co-consultation and trainee education is supported.. · What information parents value requires study..

Intention to treat: obstetrical management at the threshold of viability

BACKGROUND

Despite medical advances in the care of extremely preterm neonates and growing acceptance of resuscitation at 23 and even 22 weeks gestation, controversy remains concerning the use of antepartum obstetric intervention s that are intended to improve outcomes in the setting of anticipated extremely preterm birth. In the absence of demonstrated benefit at <23 weeks gestation and with uncertain benefit at 23 weeks gestation, previous obstetric committee opinions have advised against their use at these gestational ages.

OBJECTIVE

The purpose of this study was to review the use of obstetric intervention s at the threshold of viability based on neonatal resuscitation plan and to review the odds of survival to neonatal intensive care unit discharge based on use of obstetric intervention s with adjustment for neonatal factors.

STUDY DESIGN

This retrospective study of 6 study centers reviewed pregnant patients who were admitted between 22+0/7 and 24+6/7 weeks gestation facing delivery from 2011-2015. Patients with known anomalies or missing data were excluded. Records were reviewed for demographics, resuscitation plan, and obstetric intervention s. Mode of delivery, delivery room care, and final infant dispositions were recorded. Multiple gestations were included as 1 pregnancy in regard to the use of obstetric intervention s and were excluded from survival analysis.

RESULTS

Four hundred seventy-eight mothers met the inclusion criteria. When resuscitation was planned, mothers were more likely to receive all conventional obstetric intervention s (antenatal steroids, magnesium sulfate for neuroprotection, tocolytics, and Group Beta Streptococcus prophylaxis), regardless of gestational age at admission, and were more likely to be delivered by cesarean section (P<.05). Analyzed as a group, when antenatal steroids, magnesium sulfate, tocolytics and Group Beta Streptococcus prophylaxis were administered, the odds of survival to neonatal intensive care unit discharge increased for newborn infants who were born at 22 (odds ratio, 11.33; 95% confidence interval, 1.405-91.4) and 23 weeks gestation (odds ratio, 15.5; 95% confidence interval, 3.747-64.11; P<.05). In singletons, the odds of survival to neonatal intensive care unit discharge was not improved by cesarean delivery vs vaginal delivery, even after adjustment for the use of additional interventions, weight, gender, and gestational age (odds ratio, 1.0; 95% confidence interval, 0.59-1.8; P=.912).

CONCLUSION

In this study, when postnatal resuscitation was planned at 22 and 23 weeks gestation, women were more likely to receive antenatal steroids, magnesium sulfate, and antibiotics; provision of this bundle imparted survival benefit at 23 weeks gestation but could not be demonstrated at 22 weeks gestation because of the small sample size. These findings support of neonate-oriented obstetric interventions in the setting of delivery at 23 weeks gestation when resuscitation is planned and further exploration of optimal obstetric care when resuscitation of infants who were born at 22 weeks gestation is anticipated.
