The use of projected autonomy in antenatal shared decision-making for periviable neonates: a qualitative study.

BACKGROUND: In this study, we assessed the communication strategies used by neonatologists in antenatal consultations which may influence decision-making when determining whether to provide resuscitation or comfort measures only in the care of periviable neonates. METHODS: This study employed a qualitative study design using inductive thematic discourse analysis of 'naturally occurring data' in the form of antenatal conversations around resuscitation decisions at the grey zone of viability. The study occurred between February 2017 and June 2018 on a labor and delivery unit within a large Midwestern tertiary care hospital. Participants included 25 mothers who were admitted to the study hospital with anticipated delivery in the grey zone of viability and practicing neonatologists or neonatology fellows who partnered in antenatal consultation. We used a two-stage inductive analytic process to focus on how neonatologists' discourses constructed SDM in antenatal consultations. First, we used a thematic discourse analysis to interpret the recurring patterns of meaning within the transcribed antenatal consultations, and second, we theorized the subsequent effects of these discourses on shaping the context of SDM in antenatal encounters. RESULTS: In this qualitative study, that included discourse analysis of real-time audio conversations in 25 antenatal consults, neonatologists used language that creates projected autonomy through (i) descriptions of fetal physiology (ii) development of the fetus's presence, and (iii) fetal role in decision-making. CONCLUSION: Discourse analysis of real-time audio conversations in antenatal consultations was revelatory of how various discursive patterns brought the fetus into decision-making, thus changing who is considered the key actor in SDM.

Improving the Timeliness and Efficiency of Discharge From the NICU.

BACKGROUND: Discharge from the NICU is a highly complex process. Multidisciplinary survey results and chart audits identified gaps in the timeliness and efficiency of discharge in our NICU. Using the define-measure-analyze-improve-control quality improvement framework, we aimed to increase the percentage of patients discharged before 11:00 am from a baseline mean of 9.4% to 50% without adversely impacting caregiver readiness to discharge. METHODS: We used a fishbone diagram to identify causes of late and inefficient NICU discharge. A Pareto chart and Impact-Effort matrix were used to select targets for improvement efforts. Plan-do-study-act (PDSA) cycles established a goal unit discharge time, created a discharge checklist, prioritized rounding on discharging patients, set expectations for caregiver education completion, and increased nurse knowledge and comfort with providing caregiver education. RESULTS: The mean percent of patients discharged before 11:00 am increased from 9.4% to 52.4%, exceeding our aim. Median discharge time improved from 13:30 pm to 11:15 am (P < .001). Discharge was more efficient as demonstrated by significantly earlier completion of many discharge tasks. These improvements did not adversely impact reported caregiver readiness to discharge (75% vs 77%, P = .76). CONCLUSIONS: Quality improvement methods can significantly improve the timeliness and efficiency of NICU discharge. Improvement in this complex process may be facilitated by a multidisciplinary team that offers diverse perspectives, unique process and methodologic knowledge, and the ability to appeal to all unit stakeholders. Lessons learned from this project may benefit other teams working to improve their ICU discharge process.

Profound Hypotonia and Respiratory Failure due to Suspected Nemaline Myopathy in a Preterm Infant.

Congenital myopathies, such as nemaline myopathy, may present with hypotonia and respiratory failure in the neonatal period. Respiratory function can be further compromised in affected infants by the development of chylous effusions. We present the case of a preterm male infant born at 32 6/7 weeks' gestation, who was profoundly hypotonic and required intubation at birth. His clinical course progressed from acute to chronic respiratory failure with mechanical ventilation dependence. He developed bilateral chylous pleural effusions during the newborn period. Whole exome sequencing identified an ACTA1 gene mutation leading to the presumed diagnosis of nemaline myopathy. This case highlights the need to include congenital myopathies in the differential for a preterm newborn with hypotonia and respiratory failure.

Uncertainty at the Limits of Viability: A Qualitative Study of Antenatal Consultations.

BACKGROUND AND OBJECTIVES: Antenatal consultation between a neonatologist and expectant parent(s) may determine if resuscitation is provided for or withheld from neonates born in the gray zone of viability. In this study, we sought to gain a deeper understanding of uncertainties present and neonatologists' communication strategies regarding such uncertainties in this shared decision-making. METHODS: A prospective, qualitative study using transcriptions of audio-recorded antenatal consultations between a neonatologist and expectant parent(s) was conducted. Pregnant women were eligible if anticipating delivery in the gray zone of viability (22 0/7-24 6/7 weeks' gestation). Over 18 months, 25 of 28 pregnant women approached consented to participate. Applied thematic analysis was used to inductively derive and examine conceptual themes. RESULTS: Inductive analysis of consult transcripts revealed uncertainty as a central theme. Several subthemes relating to uncertainty were also derived, including the timing of delivery, NICU course, individual characteristics (of physician, expectant parent(s), and fetus or neonate), and consequences of the decision for the expectant parent(s). Analysis revealed that uncertainty was actively managed by neonatologists through a variety of strategies, including providing more information, acknowledging the limits of medicine, acknowledging and accepting uncertainty, holding hope, and relationship building. CONCLUSIONS: Uncertainty is pervasive within the antenatal consultation for periviable neonates and likely plays a significant role in decision-making toward postnatal resuscitative efforts. Uncertainty complicated, or even paralyzed, decision-making efforts while also providing reassurance toward a positive outcome. Directions for future study should consider whether advanced communication training modulates the impact that uncertainty plays in the shared decision-making encounter.

Proposed Plasma Ammonia Reference Intervals in a Reference Group of Hospitalized Term and Preterm Neonates.

BACKGROUND: Plasma ammonia is commonly measured in the diagnostic evaluation of hospitalized newborns, but reference values are not well defined. METHODS: We prospectively enrolled newborns admitted to the level III/IV neonatal intensive care unit and level II intermediate special care nursery from January 2017 to January 2018. Infants with inborn errors of metabolism or liver disease were excluded. Plasma ammonia concentrations were measured once within the first week of life and evaluated by sex, gestational age, timing of the draw, blood collection method, and type of nutrition. Reference intervals were calculated. RESULTS: 127 neonates were included; one third (34%) were term infants born at ≥37 weeks gestation, and two thirds (66%) were born preterm at <37 weeks gestation. Median plasma ammonia concentrations were 32 µmol/L (range <10 to 86 µmol/L). Median ammonia concentrations were higher among preterm compared to term infants (35 vs. 28 µmol/L, p = 0.0119), and term female compared to term male infants (34 vs. 26 µmol/L, p = 0.0228). There was no difference in median ammonia concentrations between female and male preterm infants, based on gestational age within the preterm group, timing of the blood draw, presence of hyperbilirubinemia, blood collection method, or type of nutritional intake. CONCLUSIONS: Plasma ammonia concentrations among newborns are higher than the expected adult concentrations and may vary by gestational age and sex. Blood collection method, type of nutrition, hyperbilirubinemia, and timing of the draw do not impact concentrations. We propose a reference limit of ≤82 µmol/L for newborns less than one week of age.

Universal Electrocardiographic Screening for Long QT Syndrome in Hospitalized Neonates.

OBJECTIVE: Long QT syndrome (LQTS) is a known cause of unexpected death, leading some to recommend routine neonatal electrocardiographic (ECG) screening. We used continuous electronic heart rate corrected QT interval (QTc) monitoring to screen for interval prolongation in a cohort of hospitalized neonates to identify those at a risk of having LQTS. We hypothesized that this screening method would yield an acceptable positive predictive value (PPV). STUDY DESIGN: A cohort of 589 infants hospitalized in a level II neonatal intensive care unit were screened through continuous electronic QTc monitoring linked to an investigator-designed, computerized data sniffer. Screening was conducted from days-of-life 3 through 7 or until hospital discharge. The data sniffer alerted investigators for a 24-hour average QTc of ≥475 ms. Positively screened patients were further evaluated with 12-lead ECG. RESULTS: Positive screens were obtained in 5.6% of patients, all of whom had negative follow-up ECG testing (PPV = 0%). Furthermore, one-quarter of positively screened neonates underwent echocardiography based on ECG findings, none of which identified clinically relevant pathology. CONCLUSION: Electronic monitoring of QTc in hospitalized neonates during the first week of life was not an efficient way to identify those at a risk of having LQTS. Conversely, screening triggered unnecessary testing.
