Decision-making at the limit of viability: differing perceptions and opinions between neonatal physicians and nurses

Development of a checklist for evaluation of shared decision-making in consultation for extremely preterm delivery

OBJECTIVE

Shared decision-making (SDM) between parents facing extremely preterm delivery and the medical team is recommended to develop the best course of action for neonatal care. We aimed to describe the creation and testing of a literature-based checklist to assess SDM practices for consultation with parents facing extremely preterm delivery.

STUDY DESIGN

The checklist of SDM counseling behaviors was created after literature review and with expert consensus. Mock consultations with a standardized patient facing extremely preterm delivery were performed, video-recorded, and scored using the checklist. Intraclass correlation coefficients and Cronbach's alpha were calculated.

RESULT

The checklist was moderately reliable for all scorers in aggregate. Differences existed between subcategories within classes of scorer, and between scorer classes. Agreement was moderate between expert scorers, but poor between novice scorers. Internal consistency of the checklist was excellent (Cronbach's alpha = 0.93).

CONCLUSION

This novel checklist for evaluating SDM shows promise for use in future research, training, and clinical settings.

[Ethical Attitudes and Handling in Prenatal Conflict Situations - A Survey among Obstetricians and Prenatal Diagnosticians in Germany]

OBJECTIVE

Various studies have shown that belonging to a professional group has an influence on ethical attitudes. The aim of this study was to assess and compare the attitudes and approaches of obstetrical specialists and prenatal diagnosticians in prenatal conflict situations.

METHODS

Explorative cross-sectional online survey among tertiary perinatal care centers and prenatal diagnosticians with DEGUM Level II/III in Germany. The questionnaire included questions on ethical attitudes in the perinatal context and a case presentation of a fetal hypoplastic left heart syndrome.

RESULTS

The response rate was 57.1% (310/543). 55.5% of the respondents practiced both obstetrics and prenatal diagnostics, 24.5% exclusively prenatal diagnostics, and 14.2% purely obstetrics. 27% agreed with the statement "An uncertain prognosis justifies pregnancy termination". For complex fetal malformations joint interdisciplinary counseling was advocated by 98.3%. Addressing the option of postnatal palliative treatment in a case of a hypoplastic left heart syndrome was accepted by 84.3% across all professional groups, while mentioning fetocide was more frequently cited as an option by prenatal diagnosticians than by obstetricians (57.7% vs. 34.1%).

CONCLUSION

Interdisciplinary prenatal parental counseling in complex fetal malformations is uniformly advocated by prenatal diagnosticians and obstetricians in Germany. However, different ethical attitudes appear among specialists groups with regard to the option of termination of pregnancy.

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.

Parental factors affecting their participation in decision-making for neonates with life-threatening conditions: A qualitative study Parents' participation in decision-making

BACKGROUND

Parents and healthcare professionals make decisions for neonates with life-threatening conditions (LTCs). Parents may be inadequately included. Limited studies have evaluated influential factors. We aimed to explore parental factors affecting parents' participation in decision-making (DM) for neonates with LTCs.

MATERIALS AND METHODS

A qualitative study was conducted in four level III neonatal intensive care units (NICUs) in Tehran, and twenty-two in-depth, semi-structured, face-to-face interviews were conducted in 2019. Interviews were transcribed and analyzed using a conventional content analysis approach. During the coding process, participants' words were condensed into meaning units, and 297 open-coded were extracted and then grouped into thirteen subcategories based on similarities and differences. This process was repeated until four main categories were identified.

RESULTS

Main categories and subcategories include "parental capabilities" (level of health literacy, emotional state, paradoxical feelings, and perception of the situation), "a sense of parental self-efficacy" (perception of parental role, awareness of self-abilities, and willingness to accept the parental role), "convictions" (religious beliefs and cultural values), and "living conditions" (job balance, household management and caring for siblings, and commuting) were found.

CONCLUSION

Although factors were parental, professionals who care for neonates with LTCs should be trained in family-centered care (FCC) principles to involve parents in DM. Nurses should be aware of parents' abilities and inform them of their rights. Parents' presentation at the bedside prevents their marginalization, reduces feelings of guilt, and helps them understand their baby's behavior and surrounding reality. A formal neonatal palliative care (NPC) program can encourage open communication between professionals and parents. A multidisciplinary team should consider parents' needs and values.

End-of-Life Care for Newborn Infants: A Multicenter Real-Life Prospective Study

INTRODUCTION

Most neonatal deaths in industrialized countries follow a process of redirection of care. The objectives of this study were to describe how neonates die in a middle-income country, whether there was redirection of care, and the reason for this decision.

METHODS

This was a prospective, multicenter, cross-sectional study. Neonates who died in the delivery room or in the neonatal intensive care unit in 97 hospitals over a 6-month period were included. After each neonatal death, one investigator interviewed a member of the healthcare team who had been involved in the end-of-life care process. Perinatal data, conditions that led to death, whether there was redirection of care, and details of the end-of-life process were recorded.

RESULTS

Data from 697 neonatal deaths were analyzed, which represent 80% of the total deaths occurring in Argentina in that period. The main causes of death were complications of prematurity (47%) and congenital anomalies (27%). Overall, 32% of neonates died after a process of redirection of care, and this was less frequent in the neonatal intensive care unit (28%) than in the delivery room (70%, p < 0.001). The reasons for withholding/withdrawing care were inevitable death (75%) and severe compromise of expected quality of life (25%). Redirection of care consisted in withholding therapies in 66% and withdrawal in 34%. A diagnosis of a major congenital anomaly increased the odds of redirection of care (OR 5.45; 95% CI: 3.59-8.27).

CONCLUSION

Most neonates who die in Argentina do so while receiving full support. Redirection of care mainly follows a condition of inevitable death.

Public Attitudes Toward Ethics and Practices in End-of-Life Decision-Making for Neonates

Importance

Attitudes toward end-of-life decision-making in neonatology have been studied in physicians and other health care professionals and are mostly shaped by their clinical education and work experiences. In contrast, attitudes among the general public have not yet been investigated.

Objective

To assess (1) attitudes in the general public toward euthanasia and withdrawal of life-prolonging treatment in neonates with severe life-limiting conditions, (2) knowledge of current German recommendations, and (3) values in the German society regarding ethical issues and proxy decisions at the beginning of life.

Design, Setting, and Participants

This cross-sectional study was performed in Germany and used an exploratory design to analyze responses to an interview conducted by an independent, established commissioned polling institute in March and April 2022. Participants were 16 years or older, with German language fluency and comprehension and living in Germany.

Main Outcomes and Measures

Knowledge about recommendations for euthanasia and withdrawal of life-prolonging treatment as well as personal attitudes toward (1) euthanasia and withdrawal of life-prolonging treatment and (2) surrogate end-of-life decision-making for newborn infants were assessed.

Results

The study included 2116 participants (1077 females [50.9%]; mean [SD] age 52.1 [18.7] years). Of the participants, 16.8% (311 of 1851) reported knowing the German recommendations for euthanasia and withdrawal of life-prolonging treatment for neonates. Euthanasia and withdrawal of life-prolonging treatment were supported by 64.7% (1369 of 2116) and 77.9% (1649 of 2116) of respondents, respectively. Shared decision-making between parents and physicians for neonates in end-of-life situations was supported by 65.6% of participants (1388). In situations where shared decision-making was not possible, 73.4% of respondents (1019 of 1388) put the ultimate decision to the parents. The magnitude of the associations was low between sociodemographic factors and views on ethical issues and customary practices involved in end-of-life decisions for neonates.

Conclusions and Relevance

Results of this cross-sectional study suggested that most respondents were not aware of the national German recommendations for euthanasia and withdrawal of life-prolonging treatment for sick and extremely preterm newborns. When counseling parents of periviable newborns, clinicians may need to exert more effort in explaining the legal and ethical framework; a highly individualized approach is warranted.

German obstetrician's self-reported attitudes and handling in threatening preterm birth at the limits of viability

OBJECTIVES

Antenatal treatment and information influences the course of pregnancy and parental decision-making in cases of threatened prematurity on the borderline of viability. Numerous studies have shown significant interprofessional differences in assessing ethical boundary decisions; hence, this study aimed to evaluate obstetricians attitudes, practices and antenatal parental counseling regarding threatened preterm birth in Germany.

METHODS

An anonymous online questionnaire was administered to 543 obstetricians at tertiary perinatal centers and prenatal diagnostic centers in Germany. The survey contained questions on basic ethical issues assessed using the Likert scale and a case vignette regarding the practical procedures of an imminent extreme premature birth at 23 1/7 gestational weeks.

RESULTS

In the case of unstoppable preterm birth, 15 % of clinicians said they would carry out a cesarean section; however, specialists from centers with a high number of very low birth weight infants would do so significantly more often. Among respondents, 29.8 % did not take any therapeutic measures without discussing the child's treatment options with their parents, 19.9 % refused to offer actionable advice to the parents, and 57 % said they would advise parents to seek intensive care treatment for the child with the option of changing treatment destination in the event of serious complications. Moreover, 84 % said they would provide information together with neonatologists.

CONCLUSIONS

Joint counseling with neonatologists is widely accepted. The size of the perinatal center significantly influences the practical approach to threatened preterm births. Respect for parents' decision-making autonomy regarding the child's treatment options is central and influences therapy initiation.

Management of the smaller twin with impending compromise in twin pregnancies complicated by selective fetal growth restriction: a questionnaire-based study of clinical practice patterns

BACKGROUND

In twin pregnancies complicated by selective fetal growth restriction (sFGR), if the smaller twin is in the state of impending intra-uterine death (IUD), immediate delivery will reduce the risk of IUD of the smaller twin while exposing the larger twin to iatrogenic preterm birth (PTB). Therefore, the management options would either be to maintain pregnancy for the maturation of the larger twin despite the risk of IUD of the smaller twin or immediate delivery to prevent IUD of the smaller twin. However, the optimal gestational age of management transition from maintaining pregnancy to immediate delivery has not been established. The objective of this study was to evaluate the physician's perspective on the optimal timing of immediate delivery in twin pregnancies complicated by sFGR.

METHODS

An online cross-sectional survey was performed with obstetricians and gynecologists (OBGYN) in South Korea. The questionnaire asked the following: (1) whether participants would maintain or immediately deliver a twin pregnancy complicated by sFGR with signs of impending IUD of the smaller twin; (2) the optimal gestational age of management transition from maintaining pregnancy to immediate delivery in a twin pregnancy with impending IUD of the smaller twin; and (3) the limit of viability and intact survival in general preterm neonates.

RESULTS

A total of 156 OBGYN answered the questionnaires. In a clinical scenario of dichorionic (DC) twin pregnancy complicated by sFGR with signs of impending IUD of the smaller twin, 57.1% of the participants answered that they would immediately deliver the twin pregnancy. However, 90.4% answered that they would immediately deliver the pregnancy in the same scenario for monochorionic (MC) twin pregnancy. The participants designated 30 weeks for DC twin and 28 weeks for MC twin pregnancies as the optimal gestational age of management transition from maintaining pregnancy to immediate delivery. The participants regarded 24 weeks as the limit of viability and 30 weeks as the limit of intact survival in general preterm neonates. The optimal gestational age of management transition for DC twin pregnancy was correlated with the limit of intact survival in general preterm neonates (p < 0.001), but not with the limit of viability. However, the optimal gestational age of management transition for MC twin pregnancy was associated with both the limit of intact survival (p = 0.012) and viability with marginal significance (p = 0.062).

CONCLUSIONS

Participants preferred to immediately deliver twin pregnancies complicated by sFGR with impending IUD of the smaller twin at the limit of intact survival (30 weeks) for DC twin pregnancies and at the midway between the limit of intact survival and viability (28 weeks) for MC twin pregnancies. More research is needed to establish guidelines regarding the optimal delivery timing for twin pregnancies complicated by sFGR.

Moral distress among neonatologists working in neonatal intensive care units in Greece: a qualitative study

BACKGROUND

Working as a neonatologist in a neonatal intensive care unit (NICU) is stressful and involves ethically challenging situations. These situations may cause neonatologists to experience high levels of moral distress, especially in the context of caring for extremely premature infants (EPIs). In Greece, moral distress among neonatologists working in NICUs remains understudied and warrants further exploration.

METHODS

This prospective qualitative study was conducted from March to August 2022. A combination of purposive and snowball sampling was used and data were collected by semi-structured interviews with twenty neonatologists. Data were classified and analyzed by thematic analysis approach.

RESULTS

A variety of distinct themes and subthemes emerged from the analysis of the interview data. Neonatologists face moral uncertainty. Furthermore, they prioritize their traditional (Hippocratic) role as healers. Importantly, neonatologists seek third-party support for their decisions to reduce their decision uncertainty. In addition, based on the analysis of the interview data, multiple predisposing factors that foster and facilitate neonatologists' moral distress emerged, as did multiple predisposing factors that are sometimes associated with neonatologists' constraint distress and sometimes associated with their uncertainty distress. The predisposing factors that foster and facilitate neonatologists' moral distress thus identified include the lack of previous experience on the part of neonatologists, the lack of clear and adequate clinical practice guidelines/recommendations/protocols, the scarcity of health care resources, the fact that in the context of neonatology, the infant's best interest and quality of life are difficult to identify, and the need to make decisions in a short time frame. NICU directors, neonatologists' colleagues working in the same NICU and parental wishes and attitudes were identified as predisposing factors that are sometimes associated with neonatologists' constraint distress and sometimes associated with their uncertainty distress. Ultimately, neonatologists become more resistant to moral distress over time.

CONCLUSIONS

We concluded that neonatologists' moral distress should be conceptualized in the broad sense of the term and is closely associated with multiple predisposing factors. Such distress is greatly affected by interpersonal relationships. A variety of distinct themes and subthemes were identified, which, for the most part, were consistent with the findings of previous research. However, we identified some nuances that are of practical importance. The results of this study may serve as a starting point for future research.

Factors Influencing the Initiative Behavior of Intensive Care Unit Nurses toward End-of-Life Decision Making: A Cross-Sectional Study

Background: Although the importance of intensive care unit (ICU) nurse initiative in end-of-life (EOL) decision making has been confirmed, there are few studies on the nurses' initiative in EOL situations. Objectives: To explore the role and mechanism of facilitators/barriers and perceived stress on the behavior of ICU nurses that initiate EOL decision making (i.e., initiative behavior). Design: This research adopted a cross-sectional descriptive design. Setting/Participants: A questionnaire composed of demographics, facilitators/barriers scale, perceived stress scale, and initiative behavior for EOL decision-making scale was used for registered ICU nurses in five tertiary general hospitals in Zhejiang Province, China. Results: The average score of the EOL decision initiative behavior was 5.54 on a range of 2-10. The results of correlation analysis indicated that the facilitators promote the initiative behavior, whereas the barriers interfere with initiative behavior. Facilitators/barriers in the EOL decision-making process significantly predicted the initiative behavior of ICU nurses in decision making (β = 0.698, p < 0.001). Facilitators/barriers had a significant indirect effect on the initiative behavior of ICU nurses through perceived stress. The 95% confidence interval was (-0.327 to -0.031), and the mediating effect of perceived stress accounted for 6.31% of the total effect. Conclusion: In the EOL context, the decision initiative of ICU nurses was at a medium level. Medical managers should implement intervention strategies based on the path that affects the initiative behavior of ICU nurses to reduce barriers and stress level in the decision-making process. That is, they should improve inter-team collaboration, nurse-patient communication, clarity of role responsibilities, and emotional support in dying situations to increase initiative and participation of ICU nurses in decision making.

Extremely low gestational age neonates and resuscitation: survey on perspectives of Canadian neonatologists

OBJECTIVES

Resuscitation care planning for extremely low gestational age neonates (ELGANs) is complex and ethically charged. Increasing survival at lower gestational ages has had a significant impact on this complexity. It also has an impact on healthcare resource utilization and policy development in Canada. This study sought to determine the current attitudes and practices of neonatologists in Canada, and to assess moral distress associated with resuscitation decisions in the ELGAN population. It also aimed to explore the perspectives of adopting a shared decision-making approach where further data with regard to best interests and prognosis are gathered in an individualized manner after birth.

METHODS

Neonatologists in Canadian level III NICUs were surveyed in 2020.

RESULTS

Amongst the 65 responses, 78% expressed moral distress when parents request non-resuscitation at 24 weeks. Uncertainty around long-term outcomes in an era with improved chances of morbidity-free survival was the most prominent factor contributing to moral distress. 70% felt less moral distress deciding goals of care after the baby's initial resuscitation and preferred an individualized approach to palliation decisions based on postnatal course and assessment.

CONCLUSIONS

While most current guidelines still support the option of non-resuscitation for infants born at less than 25 weeks, we show evidence of moral distress among Canadian neonatologists that suggests the consideration of routine resuscitation from 24 weeks and above is a more ethical approach in the current era of improved outcomes. Canadian neonatologists identified less moral distress when goals of care are developed postnatally, with availability of more evidence for prognostication, instead of antenatally based primarily on gestational age.

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.

The COVID-related mental health load of neonatal healthcare professionals: a multicenter study in Italy

Background

The COVID-19 pandemic has dramatically affected healthcare professionals’ lives. We investigated the potential mental health risk faced by healthcare professionals working in neonatal units in a multicentre cross-sectional observational study.

Methods

We included all healthcare personnel of seven level-3 and six level-2 neonatal units in Tuscany, Italy. We measured the level of physical exposure to COVID-19 risk, self-reported pandemic-related stress, and mental health load outcomes (anxiety, depression, burnout, psychosomatic symptoms, and post-traumatic symptoms) using validated, self-administered, online questionnaires during the second pandemic wave in Italy (October 2020 to March 2021).

Results

We analyzed 314 complete answers. Scores above the clinical cutoff were reported by 91% of participants for symptoms of anxiety, 29% for post-traumatic symptoms, 13% for burnout, and 3% for symptoms of depression. Moreover, 50% of the participants reported at least one psychosomatic symptom. Pandemic-related stress was significantly associated with all the measured mental health load outcomes, with an Odds Ratio of 3.31 (95% confidence interval: 1.87, 5.88) for clinically relevant anxiety, 2.46 (1.73, 3.49) for post-traumatic symptoms, 1.80 (1.17, 2.79) for emotional exhaustion, and 2.75 (1.05, 7.19) for depression. Female health care professionals displayed a greater risk of anxiety, and male health care professionals and nurses, of depressive symptoms.

Conclusions

Despite the low direct clinical impact of COVID-19 in newborns, neonatal professionals, due to both living in a situation of uncertainty and personal exposure to contacts with parents and other relatives of the newborns, and having to carry out activities once routine and now fraught with uncertainty, displayed clear signs of mental health load outcomes. They must be considered a specific population at risk for psychological consequences during the pandemic.

Ethische Fragen im Gesundheitswesen als Gegenstand interprofessionellen Lernens: Überblick zur Situation in Deutschland und Projektbericht

Interprofessionelles Lernen von Auszubildenden der Pflegeberufe sowie Medizinstudierenden bietet vielfältige Chancen für die zukünftige Zusammenarbeit mit dem Ziel einer qualitativ hochwertigen Versorgung von Patient*innen. Expert*innengremien fordern daher eine frühzeitige Integration von interprofessionellen Lehr- und Lernformaten, um effektive und nachhaltige Verbesserungen in der Praxis erreichen zu können. In Deutschland wird interprofessionelle Lehre in der grundständigen Ausbildung der zwei Professionen in wachsendem Umfang in ausgewählten Fächern – obligat oder fakultativ – eingesetzt. Der Bereich der Ethik im Gesundheitswesen wird dabei bislang jedoch kaum berücksichtigt. Der Beitrag untersucht die Situation interprofessioneller Ethiklehre in Deutschland und beleuchtet deren Möglichkeiten und Grenzen vor dem Hintergrund eines Pilotprojektes.

The Meaning Given to Bioethics as a Source of Support by Physicians Who Care for Children Who Require Long-Term Ventilation

The role and potential of bioethics input when a child requires the initiation of technology dependence to sustain life is relatively unknown. In particular, little is understood about the meaning physicians give to bioethics as a source of support during the care of children in pediatric intensive care who require long-term ventilation (LTV). We used a hermeneutic phenomenological approach to underpin the collection and analysis of data. Unstructured interviews of 40 physicians in four countries took place during 2020. We found that elements of trust, communication and acceptance informed the physicians' perceptions of the relationship with bioethics. These ranged from satisfaction to disappointment with their input into critical decisions. Bioethics services have potential to help physicians gain clarity over distressing and complex care decisions, yet physicians perceive the service inconsistently as a means of support. This research provides a sound basis to guide more beneficial interactions between clinicians and bioethics services.

Nurses' involvement in end-of-life decisions in neonatal intensive care units

BACKGROUND

End-of-life decision-making for terminally ill neonates raises important legal and ethical issues. In Greece, no recent data on nurses' attitudes and involvement in end-of-life decisions are available.

RESEARCH QUESTION/AIM

To investigate neonatal nurses' attitudes and involvement in end-of-life decisions and the relation to their socio-demographic and work-related background data.

RESEARCH DESIGN

A survey was carried out in 28 neonatal intensive care units between September 2018 and January 2019. A structured questionnaire was distributed by post.

PARTICIPANTS AND RESEARCH CONTEXT

The questionnaire was answered anonymously by 312 nurses (response rate, 71.1%) and returned to the investigators.

ETHICAL CONSIDERATIONS

The study was approved by the Bioethics and Research Committee of Aretaieio Hospital in accordance with the Helsinki Declaration.

FINDINGS

Nurses more often reported involvement in various end-of-life decisions, such as continuation of treatment without adding further therapeutic interventions for terminally ill neonates, while less reported were mechanical ventilation withdrawal and drug administration to end life. Nurses with a high attitude score, reflecting a more quality-of-life approach, were more likely to be involved in setting limits to intensive care. α low score was consistent with life preservation. Nurses' religiousness (p = 0.097), parenthood (p = 0.093), involvement in daily practice (p = 0.03), and position on the existing legal framework (p < 0.002) influenced their attitude score.

DISCUSSION

The likelihood of nurses to support interventions in neonates with poor prognosis in neonatal intensive care units was related to their attitudes. After adjusting for potential confounders, the most important predictors for nurses' attitudes were parenthood, involvement in daily practice, and position supporting current legislation reform.

CONCLUSION

Variability in involvement in end-of-life decisions among nurses exists on a national level.

How to support parents and healthcare professionals in the decision-making process of tube feeding in children?

BACKGROUND

Tube feeding in children has a severe psychosocial impact on children and their families. Parents also feel that they have limited communication with healthcare professionals (HCPs) about decision-making and the implications of tube feeding.

OBJECTIVE

This study focussed on the parents' experiences and expectations about tube feeding of children and a solution to improve the management and communication of it.

METHODS

We applied a design thinking method in two parts. First, focus groups and individual interviews were conducted with parents of children aged 0-10 years who are or had been tube fed and HCPs. Thereafter, two sounding boards with HCPs and parents were convened to discuss improvements in the management of tube feeding.

RESULTS

In total, 17 parents participated in the study. Two main topics derived from the focus groups and interviews: psychosocial impact and communication with HCPs. The sounding boards (five HCPs and two parents) divided the challenges of tube feeding into three stages: the moment tube feeding is considered, the insertion of the tube in the hospital, and transfer to the domestic environment and follow-up. Interview topics were used to develop a communication sheet to support the decision process of tube feeding.

CONCLUSIONS

The empowerment of parents in the process of tube feeding is important. More attention should be paid to alternatives, consequences, and planning for the long term. The developed communication sheet offers suggestions for issues to discuss and could support communication between parents and HCPs about tube feeding.

Swiss neonatal caregivers express diverging views on parental involvement in shared decision-making for extremely premature infants

AIM

Due to scarce available national data, this study assessed current attitudes of neonatal caregivers regarding decisions on life-sustaining interventions, and their views on parents' aptitude to express their infant's best interest in shared decision-making.

METHODS

Self-administered web-based quantitative empirical survey. All 552 experienced neonatal physicians and nurses from all Swiss NICUs were eligible.

RESULTS

There was a high degree of agreement between physicians and nurses (response rates 79% and 70%, respectively) that the ability for social interactions was a minimal criterion for an acceptable quality of life. A majority stated that the parents' interests are as important as the child's best interest in shared decision-making. Only a minority considered the parents as the best judges of what is their child's best interest. Significant differences in attitudes and values emerged between neonatal physicians and nurses. The language area was very strongly associated with the attitudes of neonatal caregivers.

CONCLUSION

Despite clear legal requirements and societal expectations for shared decision-making, survey respondents demonstrated a gap between their expressed commitment to shared decision-making and their view on parental aptitude to formulate their infant's best interest. National guidelines need to address these barriers to shared decision-making to promote a more uniform nationwide practice.

Neonatal End-of-Life Decision Making: The Possible Behavior of Greek Physicians, Midwives, and Nurses in Clinical Scenarios

Background: This study investigates the acceptability, bioethical justification, and determinants of the provision of intensive care to extremely preterm or ill neonates among healthcare professionals serving in NICUs in Greek hospitals. Methods: Healthcare professionals (71 physicians, 98 midwives, and 82 nurses) employed full-time at all public Neonatal Intensive Care Units (NICUs) (n = 17) in Greece were asked to report their potential behavior in three clinical scenarios. Results: The majority of healthcare professionals would start and continue intensive care to (a) an extremely preterm neonate, (b) a full-term neonate with an unfavorable prognosis, and (c) a neonate with complete phocomelia. In cases (a) and (b), midwives and nurses compared to physicians (p = 0.009 and p = 0.004 in scenarios (a) and (b), respectively) and health professionals ascribing to the quality-of-life principle compared to those ascribing to the intrinsic value of life (p = 0.001 and p = 0.01 scenarios (a) and (b) respectively), tend towards withholding or withdrawing care. Religion plays an important role in all three scenarios (p = 0.005, p = 0.017 and p = 0.043, respectively). Conclusions: Understanding healthcare professionals’ therapeutic intensiveness in the face of NICU ethical dilemmas can improve NICU policies, support strategies, and, consequently, the quality of neonatal intensive care.

Evaluation of NICU Healthcare Providers' Experience of Patient Ethics and Communication Excellence (PEACE) Rounds

BACKGROUND

Neonatal intensive care (NICU) providers may experience distress due to controversial orders or the close relationships they form with neonates' families. A "Patient Ethics and Communications Excellence [PEACE] Rounds" intervention developed at Indiana University proved to significantly relieve distress by facilitating interdisciplinary discussions of clinically and ethically challenging issues associated with pediatric intensive care (PICU) patient care. NICU healthcare providers face similar challenges and will benefit from understanding the potential efficacy of PEACE Rounds in this setting.

PURPOSE

This study describes the experiences of NICU healthcare providers who participate in PEACE Rounds and evaluates their perceptions of how it affects their distress levels, contributes to interdisciplinary collaboration, and influences their understanding of ethical decision-making.

METHODS

Researchers conducted semi-structured interviews with 24 intervention participants, observed 12 interventions, facilitated a validation focus group, and performed a constructionist thematic analysis and triangulation based on data from transcribed recordings.

FINDINGS

PEACE Rounds improved interdisciplinary communication and collaboration and demonstrated restorative value through the benefits of voice and collective support. The intervention may reduce, but not replace, the need for formal ethics consultations.

IMPLICATIONS FOR PRACTICE

PEACE Rounds may potentially improve interdisciplinary communications and collaboration, relieve employee distress, and reduce ethics consultations.

IMPLICATIONS FOR RESEARCH

Studies of PEACE Rounds undertaken in other clinical settings, and facilitated by a nurse educator, will help assess the potential benefits of greater reach and access and the efficacy of less structured ethics discussions.

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.

When should intensive care be provided for the extremely preterm infants born at the margin of viability? A survey of Australasian parents and clinicians

AIM

This study aimed to explore clinician and parent opinions of risk limits on resuscitation and intensive care (IC) for extremely premature infants born at the margin of viability.

METHODS

Two anonymous on-line surveys were conducted from August 2016 to January 2017. Survey participants were: (i) clinicians affiliated with neonatal intensive care units in Australia; and (ii) parents or individuals who expressed interest in premature babies through the Facebook page of Miracle Babies Foundation.

RESULTS

A total of 961 responses were received. Among 204 clinicians, 52% were neonatologists, 22% obstetricians, 20% neonatal intensive care unit nurses and 4% were midwives. Among 757 parents, 98% had a premature baby. Only 75% of clinicians responded to the risk limits questions. Median mortality risk above which they would not recommend resuscitation/IC was 70% (interquartile range (IQR) 50-80%); major disability risk in survivors 60% (IQR 50-75%); and composite risk of mortality and major disability 70% (IQR 50-80%). All parents answered the risk limit questions. The median mortality risk for not planning resuscitation was 90% (IQR 60-90%); major disability risk in survivors 50% (IQR 30-90%); and composite risk 90% (IQR 50-90%). Most clinicians (82%) stated that decisions should be guided by parent opinions if there are uncertainties. Parents had varying perception of previous counselling, and 57% stated that both their viewpoint and doctor's predicted risk influenced their decision-making.

CONCLUSIONS

Clinicians and parents had different views on mortality and major disability risks when deciding on resuscitation/neonatal IC treatment. When there was uncertainty, both agreed on working together.

National Divergences in Perinatal Palliative Care Guidelines and Training in Tertiary NICUs

Objectives: Despite established principles of perinatal palliative care (PnPC), implementation into practice has shown inconsistencies. The aim of this study was to assess PnPC services, examine healthcare professionals (HCPs) awareness and availability of PnPC guidelines, and describe HCPs satisfaction with PC and guidelines. Material and Methods: A nationwide survey was conducted in Swiss tertiary NICUs between April-November 2019. Data were examined by descriptive statistics and linear regression models. Results: Overall response rate was 54% (65% physicians; 49% nurses; 72% psychosocial staff). Half of professionals (50%) received education in PC during their medical/nursing school, whereas 36% indicated they obtained further training in PnPC at their center. PnPC guidelines were available in 4/9 centers, with 68% HCPs being aware of the guideline. Professionals who had access to a PnPC team (P = 0.001) or were part of the nursing (P = 0.003) or psychosocial staff (P = 0.001) were more likely aware of having a guideline. Twenty-eight percent indicated being satisfied with PC in their center. Professionals with guideline awareness (P = 0.025), further training (P = 0.001), and access to a PnPC team (P < 0.001) were more likely to be satisfied, whereas HCPs with a nursing background (P < 0.001) were more likely to be dissatisfied. A majority expressed the need for a PnPC guideline (80%) and further PC training (94%). Conclusion: This study reveals lacking PnPC guidelines and divergences regarding onsite opportunities for continued training across Swiss level III NICUs. Extending PnPC guidelines and training services to all centers can help bridge the barriers created by fragmented practice.

Psychometric properties of the Chinese version of the End-of-Life Decision-Making and Staff Stress Questionnaire

Background/objective

The goal of this study is to establish a Chinese version of the End-of-Life Decision Making and Associated Staff Stress Questionnaire to assess its reliability and validity.

Method

A sample of 119 Intensive Care Unit physicians and 485 nurses in China completed the questionnaire, along with questionnaires assessing motional exhaustion subscale, Stress Overload Scale, and other variables associated with end-of-life decision.

Results

Seven factors obtained via exploratory factor analysis could explain 70.61% of the total variance. Confirmatory factor analysis demonstrated an acceptable model fit with Root Mean Square Error of Approximation (RMSEA) being .078 and Standardized Root Mean Square Residual (SRMR) being .066. Validity evidence based on relationships with other variables was provided by positive or negative correlations between the questionnaire subscales and emotional exhaustion, stress overload, and other variables associated with end-of-life decision. The average content validity index was .96. The Cronbach’s α and test–retest reliability was outstanding.

Conclusions

The Chinese version of the End-of-Life Decision Making and Associated Staff Stress Questionnaire is a reliable and valid instrument for measuring the facilitators and hinders to facilitate the end-of-life decision-making, communication and the associated pressure perceived by relevant Intensive Care Unit medical staff among the Chinese population.

Decision-making at the limit of viability

Babies born at the limit of viability have a high risk of morbidity and mortality. Despite great advances in science, the approach to these newborns remains challenging. Thus, this study reviewed the literature regarding the treatment of newborns at the limit of viability. There are several interventions that can be applied before and after birth to increase the baby's survival with the least sequelae possible, but different countries make different recommendations on the gestational age that each treatment should be given. There is more consensus on the extremities of viability, being that, at the lower extremity, comfort care is preferred and active care in newborns with higher gestational age. The higher the gestational age at birth, the higher the survival and survival without morbidity rates. At all gestational ages, it is important to take into account the suffering of these babies and to provide them the best quality of life possible. Sometimes palliative care is the best therapeutic approach. The parents of these babies should be included in the decision-making process, if they wish, always respecting their needs and wishes. Nevertheless, the process of having such an immature child can be very painful for parents, so it is also important to take into account their suffering and provide them with all the necessary support. This support should be maintained even after the death of the newborn.

Decision aids available for parents making end-of-life or palliative care decisions for children: A scoping review

AIM

To identify and assess the quality of decision aids that align the decision, values and information provided for parents making end-of-life or palliative care decisions for children with life-threatening conditions.

METHODS

Six databases and the grey literature were searched in December 2018. Two reviewers independently reviewed database citations, and one reviewed grey literature citations. Citation chaining via Scopus was conducted. Quality was assessed using IPDAS Collaboration Criteria.

RESULTS

After reviewing 18 671 database citations and 10 988 grey literature citations, 18 citations describing 11 decision aids remained. Decision aids targeted premature infants, children requiring airway management, children with cancer and children with scoliosis. Three aids underwent testing beyond initial development. Quality scores averaged 27 of 50 points.

CONCLUSIONS

There are few high-quality decision aids available for use and a lack evidence of widespread clinical use. Additional research is needed to support systematic development and the use of decision aids with families.

Neonatologists and neonatal nurses have positive attitudes towards perinatal end-of-life decisions, a nationwide survey

AIM

Perinatal death is often preceded by an end-of-life decision (ELD). Disparate hospital policies, complex legal frameworks and ethically difficult cases make attitudes important. This study investigated attitudes of neonatologists and nurses towards perinatal ELDs.

METHODS

A survey was handed out to all neonatologists and neonatal nurses in all eight neonatal intensive care units in Flanders, Belgium in May 2017. Respondents indicated agreement with statements regarding perinatal ELDs on a Likert-scale and sent back questionnaires via mail.

RESULTS

The response rate was 49.5% (302/610). Most neonatologists and nurses found nontreatment decisions such as withholding or withdrawing treatment acceptable (90-100%). Termination of pregnancy when the foetus is viable in cases of severe or lethal foetal problems was considered highly acceptable in both groups (80-98%). Physicians and nurses do not find different ELDs equally acceptable, e.g. nurses more often than physicians (74% vs 60%, p = 0.017) agree that it is acceptable in certain cases to administer medication with the explicit intention of hastening death.

CONCLUSION

There was considerable support for both prenatal and neonatal ELDs, even for decisions that currently fall outside the Belgian legal framework. Differences between neonatologists' and nurses' attitudes indicate that both opinions should be heard during ELD-making.

Barriers to and Facilitators of End-of-Life Decision Making by Neonatologists and Neonatal Nurses in Neonates: A Qualitative Study

CONTEXT

Making end-of-life decisions (ELDs) in neonates involves ethically difficult and distressing dilemmas for health care providers. Insight into which factors complicate or facilitate this decision-making process could be a necessary first step in formulating recommendations to aid future practice.

OBJECTIVES

This study aimed to identify barriers to and facilitators of the ELD-making process as perceived by neonatologists and nurses.

METHODS

We conducted semistructured face-to-face interviews with 15 neonatologists and 15 neonatal nurses, recruited through four neonatal intensive care units in Flanders, Belgium. They were asked what factors had facilitated and complicated previous ELD-making processes. Two researchers independently analyzed the data, using thematic content analysis to extract and summarize barriers and facilitators.

RESULTS

Barriers and facilitators were found at three distinct levels: the case-specific context (e.g., uncertainty of the diagnosis and specific characteristics of the child, parents, and health care providers, which make decision making more difficult), decision-making process (e.g., multidisciplinary consultations and advance care planning, which make decision making easier), and overarching structure (e.g., lack of privacy and complex legislation making decision making more challenging).

CONCLUSION

Barriers and facilitators found in this study can lead to recommendations, some simpler to implement than others, to aid the complex ELD-making process. Recommendations include establishing regular multidisciplinary meetings to include all health care providers and reduce unnecessary uncertainty, routinely implementing advance care planning in severely ill neonates to make important decisions beforehand, creating privacy for bad-news conversations with parents, and reviewing the complex legal framework of perinatal ELD making.

Moral Distress in the Neonatal Intensive Care Unit: What Is It, Why It Happens, and How We Can Address It

Moral distress is prevalent in the neonatal intensive care unit (NICU), where decisions regarding end-of-life care, periviable resuscitation, and medical futility are common. Due to its origins in the nursing literature, moral distress has primarily been reported among bedside nurses in relation to the hierarchy of the medical team. However, it is increasingly recognized that moral distress may exist in different forms than initially described and that healthcare professions outside of nursing experience it. Advances in medical technology have allowed the smallest, sickest neonates to survive. The treatment for critically ill infants is no longer simply limited by the capability of medical technology but also by moral and ethical boundaries of what is right for a given child and family. Shared decision-making and the zone of parental discretion can inform and challenge the medical team to balance the complexities of patient autonomy against harm and suffering. Limited ability to prognosticate and uncertainty in outcomes add to the challenges faced with ethical dilemmas. While this does not necessarily equate to moral distress, subjective views of quality of life and personal values in these situations can lead to moral distress if the plans of care and the validity of each path are not fully explored. Differences in opinions and approaches between members of the medical team can strain relationships and affect each individual differently. It is unclear how the various types of moral distress uniquely impact each profession and their role in the distinctively challenging decisions made in the NICU environment. The purpose of this review is to describe moral distress and the situations that give rise to it in the NICU, ways in which various members of the medical team experience it, how it impacts care delivery, and approaches to address it.

Perinatal palliative care: a dedicated care pathway

OBJECTIVE

Ensure access to perinatal palliative care (PnPC) to all eligible fetuses/infants/parents.

DESIGN

During 12 meetings in 2016, a multidisciplinary work-group (WG) performed literature review (Grading of Recommendations, Assessment, Development and Evaluation (GRADE) method was applied), including the ethical and legal references, in order to propose shared care pathway.

SETTING

Maternal-Infant Department of Padua's University Hospital.

PATIENTS

PnPC eligible population has been divided into three main groups: extremely preterm newborns (first group), newborns with prenatal/postnatal diagnosis of life-limiting and/or life-threatening disease and poor prognosis (second group) and newborns for whom a shift to PnPC is appropriate after the initial intensive care (third group).

INTERVENTIONS

The multidisciplinary WG has shared care pathway for these three groups and defined roles and responsibilities.

MAIN OUTCOME MEASURES

Prenatal and postnatal management, symptom's treatment, end-of-life care.

RESULTS

The best care setting and the best practice for PnPC have been defined, as well as the indications for family support, corpse management and postmortem counselling, as well suggestion for conflicts' mediation.

CONCLUSIONS

PnPC represents an emerging field within the paediatric palliative care and calls for the development of dedicated shared pathways, in order to ensure accessibility and quality of care to this specific population of newborns.

Active care of infants born between 22 and 26 weeks of gestation does not follow consensus expert recommendations

AIM

To determine the relationship between clinical practice and publication of an Australian consensus statement for management of extremely preterm infants in 2006.

METHODS

A population-based study using linked data from New South Wales, Australia for births between 22 + 0 and 26 + 6 weeks of gestation between 2000 and 2011.

RESULTS

There were 4746 births of whom 2870 were liveborn and 1876 were stillborn. Of the live births, 2041 (71%) were resuscitated, 1914 (67%) were admitted into a neonatal intensive care unit (NICU) and 1310 (46%) survived to hospital discharge. Thirty-nine (2%) stillbirths were resuscitated but none survived. No 22-week infant survived to hospital discharge. Fewer 23-week gestation infants were resuscitated between 2004 (52%) and 2005 (20%) but resuscitation rates increased by 2008 (44%). There was no difference at other gestations. Adjusted odds ratio (OR) for resuscitation was increased by birthweight (OR: 1.01), tertiary hospital birth (OR: 3.4) and Caesarean delivery (OR: 11.3) and decreased by rural residence (OR: 0.4) and male gender (OR: 0.7).

CONCLUSION

Expert recommendations may be shaped by clinical practice rather than the converse, especially for 23-week gestation infants. Recommendations should be revised regularly to include clinical practice changes.

Deliveries at extreme prematurity: outcomes, approaches, institutional variation, and uncertainty

PURPOSE OF REVIEW

Medical decision making and practices surrounding extremely premature birth remains challenging for parents and care providers alike. Recently, concerns have been raised regarding wide practice variation, selection bias, and the limitations of outcomes data in this population. The purpose of this review is to summarize the recent literature relevant to deliveries at extreme prematurity with a focus on outcomes, approaches, and institutional variation.

RECENT FINDINGS

Newer data suggest that evidence-based clinical guidelines and protocols for both pregnant women and infants at extreme prematurity are emerging and may improve care and outcomes at lower gestational ages. It has also been recently shown that wide practice variation, selection bias, and methodological limitations of outcomes data reporting with respect to deliveries at extreme prematurity exist.

SUMMARY

Counseling at extreme prematurity should prioritize eliciting parental values and preferences with the goal of personalized shared decision-making. Providers should recognize limitations in counseling families at extreme prematurity, including selection bias, institutional variation, outcomes inaccuracies, prognostic uncertainty, and implicit biases. Standardized reporting of perinatal outcomes should be developed to help alleviate current outcomes misrepresentations and improve counseling at extreme prematurity. Education for providers in advanced communication skills is needed when counseling at extreme prematurity.

End-of-Life Decisions 20 Years after EURONIC: Neonatologists' Self-Reported Practices, Attitudes, and Treatment Choices in Germany, Switzerland, and Austria

OBJECTIVE

To assess changes in attitudes of neonatologists regarding the care of extremely preterm infants and parental involvement over the last 20 years.

STUDY DESIGN

Internet-based survey (2016) involving 170 tertiary neonatal intensive care units in Austria, Switzerland, and Germany using the European Project on Parents' Information and Ethical Decision Making in Neonatal Intensive Care Units questionnaire (German edition) with minor modifications to the original survey from 1996 to 1997.

RESULTS

The 2016 survey included 104 respondents (52.5% response rate). In 2016, significantly more neonatologists reported having ever withheld intensive care treatment (99% vs 69%) and withdrawn mechanical ventilation (96% vs 61%) or life-saving drugs (99% vs 79%), compared with neonatologists surveyed in 1996-1997. Fewer considered limiting intensive care as a slippery slope possibly leading to abuse (18% vs 48%). In the situation of a deteriorating clinical condition despite all treatment, significantly more neonatologists would ask parental opinion about continuation of intensive care (49% vs 18%). In 2016, 21% of German neonatologists would resuscitate a hypothetical infant at the limits of viability, even against parental wishes.

CONCLUSIONS

Withholding or withdrawing intensive care for extremely preterm infants at the limits of viability with parental involvement has become more acceptable than it was 20 years ago. However, resuscitating extremely preterm infants against parental wishes remains an option for up to one-fifth of the responding neonatologists in this survey.

Death, Devices, and Double Effect

Along with the growing utilization of the total artificial heart (TAH) comes a new set of ethical issues that have, surprisingly, received little attention in the literature: (1) How does one apply the criteria of irreversible cessation of circulatory function (a core concept in the Uniformed Determination of Death Act) given that a TAH rarely stops functioning on its own? (2) Can one appeal to the doctrine of double effect as an ethical rationale for turning off a TAH given that this action directly results in death? And, (3) On what ethical grounds can a physician turn off a TAH in view of the fact that either the intent of such an action or the outcome is always, and necessarily, death? The aim of this article is not to answer these questions but to highlight why these questions must be explored in some depth given the growing use of TAH technology.
