Withholding or withdrawing life-sustaining treatment in extremely low gestational age neonates.

ABSTRACT:

Objective

To identify sociodemographic and clinical factors associated with withholding or withdrawing life-sustaining treatment (WWLST) for extremely low gestational age neonates.

Design

Observational study of prospectively collected registry data from 19 National Institute of Child Health and Human Development Neonatal Research Network centres on neonates born at 22-28 weeks gestation who died >12 hours through 120 days of age during 2011-2016. Sociodemographic and clinical factors were compared between infants who died following WWLST and without WWLST.

Results

Of 1168 deaths, 67.1% occurred following WWLST. Withdrawal of assisted ventilation (97.4%) was the primary modality. WWLST rates were inversely proportional to gestational age. Life-sustaining treatment was withheld or withdrawn more often for non-Hispanic white infants than for non-Hispanic black infants (72.7% vs 60.4%; 95% CI 1.00 to 1.92) or Hispanic infants (72.7% vs 67.2%; 95% CI 1.32 to 3.72). WWLST rates varied across centres (38.6-92.6%; p<0.001). The centre with the highest rate had adjusted odds 4.89 times greater than the average (95% CI 1.18 to 20.18). The adjusted odds of WWLST were higher for infants with necrotiing enterocolitis (OR 1.77, 95% CI 1.21 to 2.59) and severe brain injury (OR 1.98, 95% CI 1.44 to 2.74).

Conclusions

Among infants who died, WWLST rates varied widely across centres and were associated with gestational age, race, ethnicity, necrotiing enterocolitis, and severe brain injury. Further exploration is needed into how race, centre, and approaches to care of infants with necrotiing enterocolitis and severe brain injury influence WWLST.

Project description:BackgroundDecisions of withholding or withdrawing life sustaining-treatments in emergency department are part of current practice but the decision-making process remains poorly described in the literature.Study objectiveWe conducted a study in two phases, the first comprising a retrospective chart review study of patients dying in the ED and the second comprising survey study of health care workers at 10 urban emergency departments in France.MethodIn a first step, we analyzed medical records based on fifteen criteria of the decision-making process grouped into four categories: the collegiality, the traceability, the management and the communication as recommended by the international guidelines. In a second step, we conducted an auto-administrated survey to assess how the staff members (medical, paramedical) feel with the decision-making process.ResultsThere were 273 deaths which occurred in the ED over the study period and we included 145 (53.1%) patients. The first-step analysis revealed that the traceability of the decision and the information given to patient or the relatives were the most reported points according to the recommendations. Three of the ten emergency departments had developed a written procedure. The collegial discussion and the traceability of the prognosis assessment were significantly increased in emergency department with a written procedure as well as management of pain, comfort care, and the communication with the patient or the relatives. In the second-step analysis, among the 735 staff members asked to take part in the survey, 287 (39.0%) answered. The medical and paramedical staff expressed difficult experience regarding the announcement and the communication with the patient and the relatives.ConclusionThe management of the decision to withhold or withdraw life-sustaining treatments must be improved in emergency departments according to the guidelines. A standard written procedure could be useful in clinical practice despite the lack of experienced difference between centers with and without procedures.

Project description:ImportanceChorioamnionitis is strongly linked to preterm birth and neonatal infection. The association between histological and clinical chorioamnionitis and cognitive, behavioral, and neurodevelopmental outcomes among extremely preterm neonates is less clear. We evaluated the impact of chorioamnionitis on 18- to 22-month neurodevelopmental outcomes in a contemporary cohort of extremely preterm neonates.ObjectiveTo compare the neonatal and neurodevelopmental outcomes of 3 groups of extremely low-gestational-age infants with increasing exposure to perinatal inflammation: no chorioamnionitis, histological chorioamnionitis alone, or histological plus clinical chorioamnionitis.Design, setting, and participantsLongitudinal observational study at 16 centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. Two thousand three hundred ninety extremely preterm infants born at less than 27 weeks' gestational age (GA) between January 1, 2006, and December 31, 2008, with placental histopathology and 18 to 22 months' corrected age follow-up data were eligible.Main exposureChorioamnionitis.Main outcomes and measuresOutcomes included cerebral palsy, gross motor functional limitation, behavioral scores (according to the Brief Infant-Toddler Social and Emotional Assessment), cognitive and language scores (according to the Bayley Scales of Infant and Toddler Development, Third Edition), and composite measures of death/neurodevelopmental impairment. Multivariable logistic and linear regression models were developed to assess the association between chorioamnionitis and outcomes while controlling for important variables known at birth.ResultsNeonates exposed to chorioamnionitis had a lower GA and higher rates of early-onset sepsis and severe periventricular-intraventricular hemorrhage as compared with unexposed neonates. In multivariable models evaluating death and neurodevelopmental outcomes, inclusion of GA in the model diminished the association between chorioamnionitis and adverse outcomes. Still, histological plus clinical chorioamnionitis was associated with increased risk of cognitive impairment as compared with no chorioamnionitis (adjusted odds ratio [OR], 2.38 [95% CI, 1.32 to 4.28] without GA; adjusted OR, 2.00 [95% CI, 1.10 to 3.64] with GA as a covariate). Histological chorioamnionitis alone was associated with lower odds of death/neurodevelopmental impairment as compared with histological plus clinical chorioamnionitis (adjusted OR, 0.68 [95% CI, 0.52 to 0.89] without GA; adjusted OR, 0.66 [95% CI, 0.49 to 0.89] with GA as a covariate). Risk of behavioral problems did not differ statistically between groups.Conclusions and relevanceAntenatal exposure to chorioamnionitis is associated with altered odds of cognitive impairment and death/neurodevelopmental impairment in extremely preterm infants.

Project description:Background and objectivesAKI is associated with poor short- and long-term outcomes. Questions remain about the frequency and timing of AKI, and whether AKI is a cause of death in extremely low gestational age neonates.Design, setting, participants, & measurementsThe Recombinant Erythropoietin for Protection of Infant Kidney Disease Study examines the kidney outcomes of extremely low gestational age neonates enrolled in the Preterm Epo Neuroprotection study, a randomized, placebo-controlled trial of recombinant human erythropoietin. We included 900 of 941 patients enrolled in Preterm Epo Neuroprotection. Baseline characteristics were compared by primary exposure (severe AKI versus none/stage 1 AKI) using unadjusted logistic regression models. Cox regression models estimated the relationship between severe AKI and death after adjustment for potential confounders. Time-dependent AKI was modeled as a binary outcome and a categorical variable by stage of AKI. We fit Cox models using time-dependent AKI status lagged by <7 days before death. Landmark analyses examined the relationship of death with development of severe AKI.ResultsSevere AKI occurred in 168 of 900 (19%, 95% confidence interval, 17% to 20%) neonates, and stage 3 AKI occurred in 60 (7%, 95% confidence interval, 5% to 8%). Stage 3 AKI occurring 7 days before death (hazard ratio, 3.88; 95% confidence interval, 1.26 to 11.96), intraventricular hemorrhage (hazard ratio, 2.01; 95% confidence interval, 1.01 to 3.99) and sepsis (hazard ratio, 2.85; 95% confidence interval, 1.12 to 7.22) were all independently associated with death. Severe AKI occurring 7 days before death (hazard ratio, 2.21; 95% confidence interval, 0.92 to 5.26) was associated with death but not statistically significant. In a landmark analysis, after adjusting for potential confounders, late (after day 14 and before day 28) severe AKI was strongly associated with higher hazard of death (hazard ratio, 4.57; 95% confidence interval, 1.82 to 11.5).ConclusionsSevere AKI occurs frequently in extremely low gestational age neonates. Stage 3 AKI is associated with mortality, and this association is present 7 days before death.

Project description:Rationale & objectiveChildren born before 28 weeks' gestation are at increased risk of chronic kidney disease (CKD). Urine biomarkers may shed light on mechanistic pathways and improve the ability to forecast CKD. We evaluated whether urinary biomarkers in neonates of low gestational age (GA) are associated with a reduced estimated glomerular filtration rate (eGFR) over time.Study designA cohort study of neonates with an exploratory case-control study of a subset of the cohort.Setting & participants327 neonates born at 24-27 weeks' gestation with 2-year eGFR data from the PENUT (Preterm Erythropoietin Neuroprotection Trial) and the REPaIReD (Recombinant Erythropoietin for Prevention of Infant Renal Disease) study.Exposures11 urinary biomarkers measured at 27, 30, and 34 weeks' postmenstrual age for the primary cohort study and 10 additional biomarkers for the exploratory case-control study.OutcomeseGFR<90mL/min/1.73m2 at 2 years corrected for GA.Analytical approachLinear mixed models to assess differences in biomarker values between neonates in whom CKD did and did not develop, accounting for multiple comparisons using Bonferroni-Holm correction in the cohort study only. Cohort analyses were adjusted for sex, GA, and body mass index. Cases were matched to controls on these variables in the case-control study.ResultsAfter adjusting for weeks of GA, urinary levels of α-glutathione-S-transferase (log difference, 0.27; 95% CI, 0.12-0.43), albumin (log difference, 0.13; 95% CI, 0.02-0.25), and cystatin C (log difference, 0.19; 95% CI, 0.04-0.34) were higher in those in whom CKD developed than in those in whom it did not. Urinary albumin and cystatin C levels did not remain significantly different after Bonferroni-Holm correction. In the exploratory case-control analysis, there were no differences in any biomarkers between cases and controls.LimitationsEarly deaths and a high number of subjects without eGFR at 2 years corrected for GA.ConclusionsMeasurement of urinary biomarkers may assist in monitoring neonates who are at risk for CKD. Additional studies are needed to confirm these findings.FundingGrants from government (National Institutes of Health).Trial registrationRegistered at ClinicalTrials.gov with study number NCT01378273.Plain-language summaryApproximately 15 million neonates worldwide are born prematurely, and 2 million are born before 28 weeks' gestation. Many of these children go on to experience chronic kidney disease. Urine biomarkers may allow for early recognition of those at risk for the development of kidney disease. In this study of more than 300 children born before 28 weeks' gestational age, we found higher mean urinary levels of α-glutathione-S-transferase at 27, 30, and 34 weeks in children whose estimated glomerular filtration rate was<90mL/min/1.73m2 at 2 years compared with children whose estimated glomerular filtration rate was>90mL/min/1.73m2 at 2 years. Measurement of urinary biomarkers may assist in monitoring neonates who are at risk for chronic kidney disease. Additional studies are needed to confirm our findings.

Project description:ImportanceLow-grade periventricular-intraventricular hemorrhage is a common neurologic morbidity among extremely low-gestational-age neonates, yet the outcomes associated with this morbidity are not fully understood. In a contemporary multicenter cohort, we evaluated the impact of such hemorrhages on early (18-22 month) neurodevelopmental outcomes of extremely premature infants.ObjectiveTo compare neurodevelopmental outcomes at 18 to 22 months' corrected age for extremely low-gestational-age infants with low-grade (grade 1 or 2) periventricular-intraventricular hemorrhage with those of infants with either no hemorrhage or severe (grade 3 or 4) hemorrhage demonstrated on cranial ultrasonography.DesignLongitudinal observational study.SettingSixteen centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network.ParticipantsA total of 1472 infants born at less than 27 weeks' gestational age between January 1, 2006, and December 31, 2008, with ultrasonography results within the first 28 days of life and surviving to 18 to 22 months with complete follow-up assessments were eligible.Main exposureLow-grade periventricular-intraventricular hemorrhage.Main outcome measuresOutcomes included cerebral palsy; gross motor functional limitation; cognitive and language scores according to the Bayley Scales of Infant Development, 3rd Edition; and composite measures of neurodevelopmental impairment. Regression modeling evaluated the association of hemorrhage severity with adverse outcomes while controlling for potentially confounding variables and center differences.ResultsLow-grade hemorrhage was not associated with significant differences in unadjusted or adjusted risk of any adverse neurodevelopmental outcome compared with infants without hemorrhage. Compared with low-grade hemorrhage, severe hemorrhage was associated with decreased adjusted continuous cognitive (β, -3.91 [95% CI, -6.41 to -1.42]) and language (β, -3.19 [-6.19 to -0.19]) scores as well as increased odds of each adjusted categorical outcome except severe cognitive impairment (odds ratio [OR], 1.46 [0.74 to 2.88]) and mild language impairment (OR, 1.35 [0.88 to 2.06]).Conclusions and relevanceAt 18 to 22 months, the neurodevelopmental outcomes of extremely low-gestational-age infants with low-grade periventricular-intraventricular hemorrhage are not significantly different from those without hemorrhage. Additional study at school age and beyond would be informative.

Project description:BackgroundOne of the most important and ethically challenging decisions made for children with life-limiting conditions is withholding/withdrawing life-sustaining treatments (LST). As important (co-)decision-makers in this process, physicians are expected to have deeply and broadly developed views. However, their attitudes and experiences in this area remain difficult to understand because of the diversity of the studies. Hence, the aim of this paper is to describe physicians' attitudes and experiences about withholding/withdrawing LST in pediatrics and to identify the influencing factors.MethodsWe systematically searched Pubmed, Cinahl®, Embase®, Scopus®, and Web of Science™ in early 2021 and updated the search results in late 2021. Eligible articles were published in English, reported on investigations of physicians' attitudes and experiences about withholding/withdrawing LST for children, and were quantitative.ResultsIn 23 included articles, overall, physicians stated that withholding/withdrawing LST can be ethically legitimate for children with life-limiting conditions. Physicians tended to follow parents' and parents-patient's wishes about withholding/withdrawing or continuing LST when they specified treatment preferences. Although most physicians agreed to share decision-making with parents and/or children, they nonetheless reported experiencing both negative and positive feelings during the decision-making process. Moderating factors were identified, including barriers to and facilitators of withholding/withdrawing LST. In general, there was only a limited number of quantitative studies to support the hypothesis that some factors can influence physicians' attitudes and experiences toward LST.ConclusionOverall, physicians agreed to withhold/withdraw LST in dying patients, followed parent-patients' wishes, and involved them in decision-making. Barriers and facilitators relevant to the decision-making regarding withholding/withdrawing LST were identified. Future studies should explore children's involvement in decision-making and consider barriers that hinder implementation of decisions about withholding/withdrawing LST.
