Measuring and communicating meaningful outcomes in neonatology: A family perspective

Long-Term Outcomes of Bronchopulmonary Dysplasia Under Two Different Diagnostic Criteria: A Retrospective Cohort Study at a Chinese Tertiary Center

Unlike other complications among very low birth weight infants (VLBW), the incidence of bronchopulmonary dysplasia (BPD) has not decreased substantially, partly because of the different definitions of BPD applied by different researchers. In this retrospective cohort study, we aimed to compare the 2018 revised definition and the 2001 consensus definition of BPD proposed by the National Institute of Child Health and Human Development (NICHD), as well as to identify which definition better predicts severe respiratory morbidities or death. We included 417 infants born at a gestational age <32 weeks and classified them as having BPD or without BPD based on the two definitions, with a final follow-up at 18-24 months. We performed between-group comparisons of death and respiratory outcomes. Statistical analyses were performed using descriptive statistics, comparative tests, and receiver operating characteristic curves. The mean ± standard deviation gestational age and birth weight of the 417 eligible infants were 29.1 ± 1.4 weeks and 1186.6 ± 197.8 g, respectively. Among the included infants, five and three infants died before and after 36 weeks of post-menstrual age (PMA), respectively, with 68 and 344 infants evaluated at discharge and 36 weeks' PMA, respectively. We diagnosed 163 (39.1%) and 70 (16.8%) infants with BPD according to the 2001 and 2018 NICHD definitions, respectively. The 2001 NICHD definition displayed a higher sensitivity (0.60 vs. 0.28), better negative predictive value (0.89 vs. 0.85), and larger area under the receiver operating characteristic curve (0.66 vs. 0.57), but a lower specificity (0.65 vs. 0.87) and worse positive predictive value (0.26 vs. 0.31), than the 2018 definition for serious respiratory morbidity or mortality at a corrected age of 18-24 months. Compared with the 2018 NICHD definition of BPD, the 2001 NICHD consensus definition may result in more cases of false-positive or unclassified severity. However, it may be a better indicator of severe respiratory morbidities or death during the first 18-24 months. Nevertheless, there is a need for future studies to assess the validity of the new diagnostic criteria.

Core outcomes in neonatology: development of a core outcome set for neonatal research

BACKGROUND

Neonatal research evaluates many different outcomes using multiple measures. This can prevent synthesis of trial results in meta-analyses, and selected outcomes may not be relevant to former patients, parents and health professionals.

OBJECTIVE

To define a core outcome set (COS) for research involving infants receiving neonatal care in a high-income setting.

DESIGN

Outcomes reported in neonatal trials and qualitative studies were systematically reviewed. Stakeholders were recruited for a three-round international Delphi survey. A consensus meeting was held to confirm the final COS, based on the survey results.

PARTICIPANTS

Four hundred and fourteen former patients, parents, healthcare professionals and researchers took part in the eDelphi survey; 173 completed all three rounds. Sixteen stakeholders participated in the consensus meeting.

RESULTS

The literature reviews identified 104 outcomes; these were included in round 1. Participants proposed 10 additional outcomes; 114 outcomes were scored in rounds 2 and 3. Round 1 scores showed different stakeholder groups prioritised contrasting outcomes. Twelve outcomes were included in the final COS: survival, sepsis, necrotising enterocolitis, brain injury on imaging, general gross motor ability, general cognitive ability, quality of life, adverse events, visual impairment/blindness, hearing impairment/deafness, retinopathy of prematurity and chronic lung disease/bronchopulmonary dysplasia.

CONCLUSIONS AND RELEVANCE

A COS for clinical trials and other research studies involving infants receiving neonatal care in a high-income setting has been identified. This COS for neonatology will help standardise outcome selection in clinical trials and ensure these are relevant to those most affected by neonatal care.

Lifelong pulmonary sequelae of bronchopulmonary dysplasia

PURPOSE OF REVIEW

To summarize the current literature evaluating long-term pulmonary morbidity among surviving very preterm infants with bronchopulmonary dysplasia (BPD).

RECENT FINDINGS

BPD predisposes very preterm infants to adverse respiratory signs and symptoms, greater respiratory medication use, and more frequent need for rehospitalization throughout early childhood. Reassuringly, studies also indicate that older children and adolescents with BPD experience, on average, similar functional status and quality of life when compared to former very preterm infants without BPD. However, measured deficits in pulmonary function may persist in those with BPD and indicate an increased susceptibility to early-onset chronic obstructive pulmonary disease during adulthood. Moreover, subtle differences in exercise tolerance and activity may put survivors with BPD at further risk of future morbidity in later life.

SUMMARY

Despite advances in neonatal respiratory care, a diagnosis of BPD continues to be associated with significant pulmonary morbidity over the first two decades of life. Long-term longitudinal studies are needed to determine if recent survivors of BPD will also be at increased risk of debilitating pulmonary disease in adulthood.

Inconsistent outcome reporting in large neonatal trials: a systematic review

OBJECTIVE

Inconsistent outcome selection and reporting in clinical trials are important sources of research waste; it is not known how common this problem is in neonatal trials. Our objective was to determine whether large clinical trials involving infants receiving neonatal care report a consistent set of outcomes, how composite outcomes are used and whether parents or former patients were involved in outcome selection.

DESIGN

A literature search of CENTRAL, CINAHL, EMBASE and MEDLINE was conducted; randomised trials published between 1 July 2012 and 1 July 2017 and involving at least 100 infants in each arm were included. Outcomes and outcome measures were extracted and categorised by physiological system; reported former patient and parent involvement in outcome selection was extracted.

RESULTS

Seventy-six trials involving 43 126 infants were identified; 216 different outcomes with 889 different outcome measures were reported. Outcome reporting covered all physiological systems but was variable between individual trials: only 67/76 (88%) of trials reported survival and 639 outcome measures were only reported in a single trial. Thirty-three composite outcomes were used in 41 trials. No trials reported former patient or parent involvement in outcome selection.

CONCLUSIONS

Inconsistent outcome reporting and a lack of parent and former patient involvement in outcome selection in neonatal clinical trials limits the ability of such trials to answer clinically meaningful questions. Developing and implementing a core outcome set for future neonatal trials, with input from all stakeholders, should address these issues.

Best practice guidelines for communicating to parents the diagnosis of disability

Conveying a diagnosis of a disability to the parents of young children is difficult both for the parent and the clinician, however there is an ethical and medical imperative to do so. However, the process and manner of disclosure needs to be done well. When communication between parent and clinicians fails, parental mental health can be adversely affected. This paper adapts and explains how to use the SPIKES protocol to deliver "bad news" about a developmental disability diagnosis with families of infants <12-months old, using cerebral palsy as an example. Next, the range of responses parents experience to the delivery of bad news from "watchful waiting" to "acceptance" are outlined and explained. The knowledge needs of parents range from causes and prognosis to treatments and outcomes. Using clinical scenarios of recently diagnosed infants, commonly asked questions and suggested answers are tabled.

The Diagnosis of Bronchopulmonary Dysplasia in Very Preterm Infants. An Evidence-based Approach

Rationale: Current diagnostic criteria for bronchopulmonary dysplasia rely heavily on the level and duration of oxygen therapy, do not reflect contemporary neonatal care, and do not adequately predict childhood morbidity.Objectives: To determine which of 18 prespecified, revised definitions of bronchopulmonary dysplasia that variably define disease severity according to the level of respiratory support and supplemental oxygen administered at 36 weeks' postmenstrual age best predicts death or serious respiratory morbidity through 18-26 months' corrected age.Methods: We assessed infants born at less than 32 weeks of gestation between 2011 and 2015 at 18 centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network.Measurements and Main Results: Of 2,677 infants, 683 (26%) died or developed serious respiratory morbidity. The diagnostic criteria that best predicted this outcome defined bronchopulmonary dysplasia according to treatment with the following support at 36 weeks' postmenstrual age, regardless of prior or current oxygen therapy: no bronchopulmonary dysplasia, no support (n = 773); grade 1, nasal cannula ≤2 L/min (n = 1,038); grade 2, nasal cannula >2 L/min or noninvasive positive airway pressure (n = 617); and grade 3, invasive mechanical ventilation (n = 249). These criteria correctly predicted death or serious respiratory morbidity in 81% of study infants. Rates of this outcome increased stepwise from 10% among infants without bronchopulmonary dysplasia to 77% among those with grade 3 disease. A similar gradient (33-79%) was observed for death or neurodevelopmental impairment.Conclusions: The definition of bronchopulmonary dysplasia that best predicted early childhood morbidity categorized disease severity according to the mode of respiratory support administered at 36 weeks' postmenstrual age, regardless of supplemental oxygen use.

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.

Beyond a Seat at the Table: The Added Value of Family Stakeholders to Improve Care, Research, and Education in Neonatology

OBJECTIVES

To analyze activities involving veteran resource parents and patients in a family partnership program; their perspectives were also explored.

STUDY DESIGN

The multiple roles assumed by family stakeholders in neonatal initiatives were reviewed. Quality control questionnaires were distributed to resource parents and patients and providers who worked with them. Mixed methods were used to analyze results.

RESULTS

Thirty resource parents and patients were involved in a total of 653 activities related to clinical care (n = 413), teaching (n = 31), and research (n = 209); 7 initiatives were described to illustrate the positive impact of family stakeholders on clinical care, teaching, and/or research. Resource parents and patients had different degrees and intensity of involvement: all were involved in low-risk initiatives and 9 in more complex activities. In the questionnaire, family stakeholders all described positive impacts associated with their participation and benefits to themselves, such as meaning making. Three resource parents reported traumatic memories that occurred during medical simulations. The majority of providers report that resource parents and patients improved their projects, but some also report this new collaboration is complex.

CONCLUSIONS

Although stakeholder participation increasingly is recommended, practical knowledge and the impact of their participation is scarce. Having several resource parents and patients bring their contributions may be more valuable than a few "expert stakeholders." Recruiting and orienting resource parents and patients toward different types of activities should take into account the complexity and risks of the tasks. Family stakeholders are appreciated and have a positive impact on projects in which they are involved.

Neurodevelopmental Outcomes in Preterm Infants with White Matter Injury Using a New MRI Classification

OBJECTIVE

The aim of this study was to evaluate whether a new MRI scoring system for preterm non-haemorrhagic white matter injury (WMI), derived from the analysis of the natural evolution of WMI throughout the neonatal period until term-equivalent age, can be used for outcome prediction.

METHODS

Eighty-two infants <36 weeks gestation with WMI diagnosed from sequential cranial ultrasound and confirmed on neonatal MRI were retrospectively included. WMI was classified in four grades of severity. Neurodevelopmental data at a median age of 24 months were analysed.

RESULTS

In 74 surviving children WMI severity was strongly associated with the presence and severity of cerebral palsy (CP) and other neurodevelopmental impairments (Spearman's rank correlation 0.88, p < 0.001). Only 3 children with grade I WMI (9%) developed CP (all ambulant) and their developmental scores were not different to those from the controls, although they started walking significantly later (p = 0.036). Of the 6 children with grade II, 83% developed CP (mild in most), whereas 91% of the 34 children with grade III had CP (moderate-severe in 76%) and all had some degree of neurodevelopmental impairment. Three children with grade III WMI did not develop CP; their imaging showed, in contrast to children who developed CP, that the cysts did not affect the corticospinal tracts; also, myelin in the posterior limb of the internal capsule appeared normal in 2 children and suboptimal in 1.

CONCLUSIONS

This MRI scoring system for preterm WMI can be used to predict neurodevelopmental outcomes. Individualized assessment of the site of lesions and the progression of myelination improves prognostic accuracy.

Integrating Parents in Neonatal and Pediatric Research

BACKGROUND

Parents and their infants are the beneficiaries of neonatal and pediatric research, but in the past they have been excluded from most stages of research projects. As a result, many projects may fail to produce the most worthwhile information for parents and families. Lately, veteran resource parents and patients have been increasingly integrated in research initiatives.

METHODS

Benchmarking of neonatal and pediatric research initiatives where resource parents and/or ex neonatal patients have helped to optimize pediatric research. We review ways in which resource parents/patients can be involved in research, with examples and practical ideas of how to proceed.

RESULTS

Resource parents/patients can be collaborators in research and be integrated in many steps: prioritizing research projects, designing trials, determining the outcomes of interest, ethics review, developing and improving consent procedures, collection and interpretation of data, participation in data safety monitoring committees, publication of results, and presentation to peer groups. Some of the strategies for integration of stakeholders in clinical research are more complex, may involve risk and require more training than others.

CONCLUSION

We suggest that groups wanting to involve parents in their research endeavors start with simpler tasks that entail less risk and develop teams of resource parents who have differing interests and abilities. Quality control of programs is essential, such as frequently giving and obtaining feedback from resource parents/patients and researchers. In the future, integration of resource parents/patients into every step of clinical research will be essential to ensure that parent and family important outcomes are examined.

Parental Perspectives Regarding Outcomes of Very Preterm Infants: Toward a Balanced Approach

OBJECTIVES

To explore parental perspectives regarding their preterm child at 18 months corrected age and to investigate whether reported answers correlate with level of neurodevelopmental impairment (NDI) as defined by clinicians. We hypothesized that parents would report more negative concerns with increasing level of NDI.

STUDY DESIGN

This study included 190 infants born <29 weeks of gestational age in 2009-2012 at 1 tertiary university health center. Infants underwent detailed developmental assessment at 18 months corrected age, and were classified into either absence or presence of mild to moderate or severe NDI. Parents were asked 2 open-ended questions: "What concerns you most about your child?" and "Please describe the best things about your child." Open-ended questions were analyzed using qualitative methodology.

RESULTS

In this cohort, 49%, 43%, and 8% of participants had no, mild to moderate, and severe NDI. The majority of parents (72.8%) had both positive and negative aspects to report; 26.8% only had positive ones. The main positive themes invoked by parents included their child's personality (61%), happiness (40%), developmental outcome/progress (40%), and physical health (11%). The main themes regarding parental concerns included neurodevelopment (56%), notably language and behavior, and physical health (24%), particularly growth/nutrition and physical fragility. There was no association between positive themes and categories of NDI, but parents of children with mild to moderate NDI reported more concerns about development.

CONCLUSIONS

Neonatal outcome research would benefit from incorporating parental perspectives regarding their child, including negative and positive aspects, enabling physicians to provide complete and balanced information to parents of all preterm infants.

Prognosis as an Intervention

This article elaborates on how neonatologists and perinatologists might conceive of prognosis as an intervention with outcomes relevant to patients, families, and society at large and highlights aspects of this important area of practice requiring further study.

Emerging Methodologies in Pediatric Palliative Care Research: Six Case Studies

Given the broad focus of pediatric palliative care (PPC) on the physical, emotional, and spiritual needs of children with potentially life-limiting illnesses and their families, PPC research requires creative methodological approaches. This manuscript, written by experienced PPC researchers, describes issues encountered in our own areas of research and the novel methods we have identified to target them. Specifically, we discuss potential approaches to: assessing symptoms among nonverbal children, evaluating medical interventions, identifying and treating problems related to polypharmacy, addressing missing data in longitudinal studies, evaluating longer-term efficacy of PPC interventions, and monitoring for inequities in PPC service delivery.

Improving neonatal care with the help of veteran resource parents: An overview of current practices

Over the past decade, veteran parents who have lived a neonatal intensive care unit (NICU) experience have become increasingly involved as 'resource parents' to provide peer-to-peer support to "new" NICU parents. These parents can provide a unique form of support to new parents. They can also assume other roles in clinical care, research, administration and/or teaching, but those roles are rarely described in the literature. This article reviews many of the activities performed by resource parents in neonatology. These activities were identified/examined and classified according to the location of involvement (hospital or not), the presence/absence of direct interaction with families and providers, and the topic of involvement. We have also identified gaps in knowledge relative to recruitment and training, development and evaluation of programs, structuring of responsibilities, and remuneration of resource parents. Future research is needed to measure the impact of resource parents on neonatal care.

Parent, patient and clinician perceptions of outcomes during and following neonatal care: a systematic review of qualitative research

OBJECTIVE

Multiple outcomes can be measured in infants that receive neonatal care. It is unknown whether outcomes of importance to parents and patients differ from those of health professionals. Our objective was to systematically map neonatal care outcomes discussed in qualitative research by patients, parents and healthcare professionals and test whether the frequency with which outcomes are discussed differs between groups.

DESIGN

Systematic review of qualitative literature. The following databases were searched: Medline, CINAHL, EMBASE, PsycINFO and ASSIA from 1997 to 2017. Publications describing qualitative data relating to neonatal care outcomes, reported by former patients, parents or healthcare professionals, were included. Narrative text was analysed and outcomes grouped thematically by organ system. Permutation testing was applied to assess an association between the outcomes identified and stakeholder group.

RESULTS

Sixty-two papers containing the views of over 4100 stakeholders were identified; 146 discrete outcomes were discussed; 58 outcomes related to organ systems and 88 to other more global domains. Permutation testing provides evidence that parents, former patients and health professionals reported outcomes with different frequencies (p=0.037).

CONCLUSIONS

Parents, patients and health professionals focus on different outcomes when discussing their experience of neonatal care. A wide range of neonatal care outcomes are reported in qualitative research; many are global outcomes relating to the overall status of the infant. The views of former patients and parents should be taken into consideration when designing research; the development of a core outcomes set for neonatal research will facilitate this.

Two-Year Neurodevelopmental Outcome of an Infant Born at 21 Weeks' 4 Days' Gestation

Recent literature confirms that, at the lower limit of extrauterine survival, substantial intercenter variability exists in resuscitation practice. The reasons for this variability are unclear, but may be related to disagreement on how to apply the best interests standard to extremely premature infants. Currently, both obstetric and pediatric societies recommend against assessing for viability or attempting resuscitation before 22 weeks' gestation. In this context, we report the unimpaired 2-year outcome of a female infant resuscitated after delivery at 21 weeks' 4 days' gestation and 410 g birth weight. She may be the most premature known survivor to date. This infant had multiple risk factors for adverse outcome, including prolonged mechanical ventilation, bronchopulmonary dysplasia, and threshold retinopathy of prematurity. She achieved discharge from the hospital on low-flow oxygen at 39 weeks' 4 days' gestation and 2519 g. At 24 months' and 8 days' chronological age, she achieved cognitive, motor, and language Bayley III scores of 90, 89, and 88, equivalent to 105, 100, and 103 at 20 months 2 days corrected age. It is known that active intervention policies at 22 weeks' gestation improves the outcome for those infants and it may be reasonable to infer that these benefits would extend, if to a lesser degree, into the 21st week. Ultimately, such limited data exist at this gestational age that the time may have arrived for obstetrical centers to begin systematically reporting fetal outcomes in the 21st week.

Children's outcomes at 2-year follow-up after 4 years of structured multi-professional medical-ethical decision-making in a neonatal intensive care unit

OBJECTIVE

We reviewed our decisions about continuation/withdrawal of life-sustaining treatments in a group of critically ill newborns who were discussed in structured medical ethical decision-making meetings, and provide the surviving children's outcomes at 2-year follow-up.

STUDY DESIGN

In an explorative observational study, 61 cases were evaluated. The children involved had been discussed in such a structured way from 2009 to 2012 in a level III-D neonatal intensive care unit.

RESULTS

Decisions made were: full treatment (n=6), earlier restriction cancelled (n=3), treatment restriction (n=30) and palliative care (n=22). Parents of six children disagreed with the decision proposed. Thirteen (54%) of the 24 children who survived (39%) had moderate to severe neurological problems; 8 (33%) had additional sequelae; only one 2-year-old child was healthy.

CONCLUSIONS

Decisions made varied to a large extent. The poor outcomes should be disseminated among decision makers. Future studies must explore new ways to improve outcome prediction, extend follow-up periods and consider what living with severe handicaps really means for both child and family.
