Perinatal pathology in the context of a clinical trial: attitudes of bereaved parents

Post-mortem confirmation of fetal brain abnormalities: challenges highlighted by the MERIDIAN cohort study

OBJECTIVES

To assess and analyse the concordance between post-mortem findings and in utero magnetic resonance imaging (iuMRI) in the MERIDIAN (MRI to enhance the diagnosis of fetal developmental brain abnormalities in utero) cohort.

DESIGN

Prospective cohort study.

SETTING

Fetal medicine units in the UK.

POPULATION

Pregnant women with a diagnosis of fetal brain abnormality identified on ultrasound at 18 weeks of gestation or later.

METHODS

All pregnancies from the MERIDIAN study that resulted in a abortion were included and the rate of uptake and success of post-mortem examinations were calculated. In the cases in which diagnostic information about the fetal brain was obtained by post-mortem, the results were compared with the diagnoses from iuMRI.

MAIN OUTCOME MEASURE

Outcome reference diagnosis from post-mortem examination.

RESULTS

A total of 155 from 823 pregnancies (19%) ended in a termination of pregnancy and 71 (46%) had post-mortem brain examinations, 62 of which were diagnostically adequate. Hence, the overall rate of successful post-mortem investigation was 40%, and for those cases there was a concordance rate of 84% between iuMRI and post-mortem examination. Detailed information is provided when the results of the post-mortem examination and the iuMRI study differed.

CONCLUSIONS

We have shown tissue-validation of radiological diagnosis is hampered by a low rate of post-mortem studies in fetuses aborted with brain abnormalities, a situation further compounded by a 12% rate of autopsy being technically unsuccessful. The agreement between iuMRI and post-mortem findings is high, but our analysis of the discrepant cases provides valuable clues for improving how we provide information for parents. TWEETABLE ABSTRACT: iuMRI should be considered a reliable indicator of fetal brain abnormalities when post-mortem is not performed.

Minimally invasive autopsy for fetuses and children based on a combination of post-mortem MRI and endoscopic examination: a feasibility study

BACKGROUND

Less invasive perinatal and paediatric autopsy methods, such as imaging alongside targeted endoscopy and organ biopsy, may address declining consent rates for traditional autopsy, but their acceptability and accuracy are not known.

OBJECTIVES

The aims of this study were to provide empirical data on the acceptability and likely uptake for different types of autopsy among key stakeholders (study 1); and to analyse existing autopsy data sources to provide estimates of the potential efficacy of less invasive autopsy (LIA) and its projected utility in clinical practice (study 2).

REVIEW METHODS

Study 1: this was a mixed-methods study. Parents were involved in research design and interpretation of findings. Substudy 1: a cross-sectional survey of 859 parents who had experienced miscarriage, termination of pregnancy for fetal anomaly, stillbirth, infant or child death, and interviews with 20 responders. Substudy 2: interviews with 25 health professionals and four coroners. Substudy 3: interviews with 16 religious leaders and eight focus groups, with 76 members of the Muslim and Jewish community. Study 2: a retrospective analysis of national data in addition to detailed information from an existing in-house autopsy database of > 5000 clinical cases that had undergone standard autopsy to determine the proportion of cases by clinical indication group for which tissue sampling of specific internal organs significantly contributed to the diagnosis.

RESULTS

Substudy 1: 91% of participants indicated that they would consent to some form of LIA, 54% would consent to standard autopsy, 74% to minimally invasive autopsy (MIA) and 77% to non-invasive autopsy (NIA). Substudy 2: participants viewed LIA as a positive development, but had concerns around the limitations of the technology and de-skilling the workforce. Cost implications, skills and training requirements were identified as implementation challenges. Substudy 3: religious leaders agreed that NIA was religiously permissible, but MIA was considered less acceptable. Community members indicated that they might consent to NIA if the body could be returned for burial within 24 hours. Study 2: in 5-10% of cases of sudden unexplained death in childhood and sudden unexplained death in infants, the final cause of death is determined by routine histological sampling of macroscopically normal organs, predominantly the heart and lungs, and in this group routine histological sampling therefore remains an important aspect of investigation. In contrast, routine histological examination of macroscopically normal organs rarely (< 0.5%) provides the cause of death in fetal cases, making LIA and NIA approaches potentially highly applicable.

LIMITATIONS

A key limitation of the empirical research is that it is hypothetical. Further research is required to determine actual uptake. Furthermore, because of the retrospective nature of the autopsy data set, findings regarding the likely contribution of organ sampling to final diagnosis are based on extrapolation of findings from historical autopsies, and prospective data collection is required to validate the conclusions.

CONCLUSIONS

LIA is viable and acceptable (except for unexplained deaths), and likely to increase uptake. Further health economic, performance and implementation studies are required to determine the optimal service configuration required to offer this as routine clinical care.

"The communication and support from the health professional is incredibly important": A qualitative study exploring the processes and practices that support parental decision-making about postmortem examination

Background

Consent rates for postmortem (PM) examination in the perinatal and paediatric setting have dropped significantly in the United Kingdom, the United States, and the Western Europe. We explored the factors that act as facilitators or barriers to consent and identified processes and practices that support parental decision‐making.

Methods

A qualitative study conducted with bereaved parents, parent advocates, and health care professionals in the United Kingdom. Analysis was conducted on 439 free‐tect comments within a cross‐sectional survey, interviews with a subset of 20 survey respondents and 25 health professionals, and a focus group with five parent advocates.

Results

Three broad parental decision‐making groups were identified: 1, “Not open to postmortem examination”; 2, “Consent regardless of concerns”; and 3, “Initially undecided.” Decisional drivers that were particularly important for this “undecided” group were “the initial approach,” “adjustment and deliberation,” “detailed discussion about the procedure,” and “formal consent.” The way in which these were managed by health care staff significantly impacted whether those parents' consented to PM, particularly for those who are ambivalent about the procedure.

Conclusions

We propose a set of recommendations to improve the way PM counselling and consent is managed. Adopting such measures is likely to lead to improved family experience and more consistent and high‐quality discussion regarding PM.

What's already known about this topic?

There has been a significant decline in uptake of paediatric post mortem, despite evidence that it provides clinically useful data in between 22% and 76% of cases.

What does this study add?

This study identifies key actions by health care staff that are highly influential in whether or not parents' consent to the postmortem procedure. Recommendations for practice are also provided.

Hospital Practices for Parents Following Perinatal Loss

The aim of this study is to provide comprehensive and current information on hospital practices following perinatal death. The provinces with the highest number of hospitals in Turkey were selected for the study. To collect data, the questionnaire form of Canadian hospitals maternity policies and practices survey was sent to the appropriate respondents in hospitals. The study showed that encouraging parents to have photos of the deceased baby and preparing a remembrance pack were the most problematic issues and were not available at the majority of hospitals. The most common supportive practices in hospitals were the opportunity to see the deceased baby, assisting with funeral options and autopsies, and support for completing the necessary legal documents. The result indicated that hospitals implement varied practices in assisting the bereaved parents. The study recommended developing hospital policies and practices related to perinatal death and supporting families during their loss and grief.

Understanding mothers' decision-making needs for autopsy consent after stillbirth: Framework analysis of a large survey

BACKGROUND

Experiencing stillbirth is devastating and leaves parents searching for causes. Autopsy is the gold standard for investigation, but deciding to consent to this procedure is very difficult for parents. Decision support in the form of clear, consistent, and parent-centered information is likely to be helpful. The aims of this study were to understand the influences on parents' decisions about autopsy after stillbirth and to identify attributes of effective decision support that align with parents' needs.

METHODS

Framework analysis using the Decision Drivers Model was used to analyze responses from 460 Australian and New Zealand (ANZ) mothers who took part in a multi-country online survey of parents' experiences of stillbirth. The main outcomes examined were factors influencing mothers' decisions to consent to autopsy after stillbirth.

RESULTS

Free-text responses from 454 ANZ mothers referenced autopsy, yielding 1221 data segments for analysis. The data confirmed the difficult decision autopsy consent entails. Mothers had a strong need for answers coupled with a strong need to protect their baby. Four "decision drivers" were confirmed: preparedness for the decision; parental responsibility; possible consequences; and role of health professionals. Each had the capacity to influence decisions for or against autopsy. Also prominent were the "aftermath" of the decision: receiving the results; and decisional regret or uncertainty.

CONCLUSIONS

The influences on decisions about autopsy are diverse and unpredictable. Effective decision support requires a consistent and structured approach that is built on understanding of parents' needs.

Factors affecting uptake of postmortem examination in the prenatal, perinatal and paediatric setting

Background

Postmortem examination is the single most useful investigation in providing information to parents about why their baby or child died. Despite this, uptake remains well below the recommended 75%.

Objective

To address the question ‘what are the barriers and motivators to perinatal, prenatal and paediatric PM examination?’

Search strategy

Key databases including Pubmed and CINAHL; Cochrane library, websites of relevant patient organisations, hand search of key journals, first and last authors and references.

Selection criteria

Peer‐reviewed qualitative, quantitative or mixed methods research examining factors affecting uptake or decline of perinatal or paediatric postmortem examination.

Data collection and analysis

Narrative synthesis; findings were compared across studies to examine interrelations.

Main results

Seven major themes describing barriers to postmortem uptake were identified: dislike of invasiveness, practicalities of the procedure, organ retention issues, protective parenting, communication and understanding, religion and culture and professional or organisational barriers. Six major themes related to factors which facilitated parental consent were identified: desire for information, contributing to research, coping and well‐being, respectful care, minimally invasive options, and policy and practice. There were a number of themes in the literature that reflected best practice.

Conclusion

Findings highlight the need for better health professional education and the fact some concerns may be mitigated if less invasive methods of postmortem were routinely available. New consent packages and codes of practice may have a positive impact on perception of examination after death. The landscape is changing; further research is necessary to assess the impact on postmortem uptake rates.

The ethical issues regarding consent to clinical trials with pre-term or sick neonates: a systematic review (framework synthesis) of the empirical research

BACKGROUND

Conducting clinical trials with pre-term or sick infants is important if care for this population is to be underpinned by sound evidence. Yet approaching parents at this difficult time raises challenges for the obtaining of valid informed consent to such research. This study asked: what light does the empirical literature cast on an ethically defensible approach to the obtaining of informed consent in perinatal clinical trials?

METHODS

A systematic search identified 49 studies. Analysis began by applying philosophical frameworks which were then refined in light of the concepts emerging from empirical studies to present a coherent picture of a broad literature.

RESULTS

Between them, studies addressed the attitudes of both parents and clinicians concerning consent in neonatal trials; the validity of the consent process in the neonatal research context; and different possible methods of obtaining consent.

CONCLUSIONS

Despite a variety of opinions among parents and clinicians there is a strongly and widely held view that it is important that parents do give or decline consent for neonatal participation in trials. However, none of the range of existing consent processes reviewed by the research is satisfactory. A significant gap is evaluation of the widespread practice of emergency 'assent', in which parents assent or refuse their baby's participation as best they can during the emergency and later give full consent to ongoing participation and follow-up. Emergency assent has not been evaluated for its acceptability, how such a process would deal with bad outcomes such as neonatal death between assent and consent, or the extent to which late parental refusal might bias results. This review of a large number of empirical papers, while not making fundamental changes, has refined and developed the conceptual framework from philosophy for examining informed consent in this context.

What do bereaved parents want from professionals after the sudden death of their child: a systematic review of the literature

Background

The death of a child is a devastating event for parents. In many high income countries, following an unexpected death, there are formal investigations to find the cause of death as part of wider integrated child death review processes. These processes have a clear aim of establishing the cause of death but it is less clear how bereaved families are supported. In order to inform better practice, a literature review was undertaken to identify what is known about what bereaved parents want from professionals following an unexpected child death.

Methods

This was a mixed studies systematic review with a thematic analysis to synthesize findings. The review included papers from Europe, North America or Australasia; papers had to detail parents’ experiences rather than professional practices.

Results

The review includes data from 52 papers, concerning 4000 bereaved parents. After a child has died, parents wish to be able to say goodbye to them at the hospital or Emergency Department, they would like time and privacy to see and hold their child; parents may bitterly regret not being able to do so. Parents need to know the full details about their child’s death and may feel that they are being deliberately evaded when not given this information. Parents often struggle to obtain and understand the autopsy results even in the cases where they consented for the procedure. Parents would like follow-up appointments from health care professionals after the death; this is to enable them to obtain further information as they may have been too distraught at the time of the death to ask appropriate questions or comprehend the answers. Parents also value the emotional support provided by continuing contact with health-care professionals.

Conclusion

All professionals involved with child deaths should ensure that procedures are in place to support parents; to allow them to say goodbye to their child, to be able to understand why their child died and to offer the parents follow-up appointments with appropriate health-care professionals.

What do parents want to know when considering autopsy for their child with cancer?

Research has suggested that autopsy in pediatrics is a valued way for parents to better understand and process their child's death, yet physicians often express hesitancy in discussing this topic with parents. To better assist clinicians with initiating discussion about this often sensitive topic, the current study examined bereaved parents' preferences about the timing and content of the autopsy discussion as well as reasons for considering autopsy. This study explored the views of 30 parents who lost a child to a variety of malignancies between 6 months and 6 years ago. Results showed that 36.7% of parents recalled having a discussion about autopsy, and the vast majority of those who did not recall a discussion (89.5%) would have considered an autopsy if it had been discussed. The majority of participants in this study indicated their preference to have the first conversation about autopsy when it becomes clear that cure is no longer possible. Findings suggest that educating parents about the clinical, emotional, and potential research benefits of autopsy and tissue procurement will ultimately help them make informed decisions and understand the importance of autopsy in medical progress. The future research and clinical implications of these findings are discussed.

The use of in utero MRI to supplement ultrasound in the foetus at high risk of developmental brain or spine abnormality

OBJECTIVES

It is widely accepted that the diagnosis of foetal central nervous system (CNS) abnormalities can be improved by performing MRI examinations in utero. Most of the published literature has concentrated on pregnancies in which a developmental abnormality has been detected (or suspected) on ultrasound in an otherwise low-risk pregnancy. In this paper, we test the hypothesis that in utero MRI of the foetal brain in high-risk pregnancies will detect abnormalities not shown by ultrasound at a rate that justifies its use in clinical practice.

METHODS

100 females were recruited into the study from foeto-maternal or clinical genetic departments. They all had a foetus/child with a CNS malformation from an earlier pregnancy, which led to an increased risk of recurrence being quoted for the present pregnancy. All in utero MRI examinations were performed on 1.5 T clinical MRI systems at 18 weeks gestational age or later.

RESULTS

In 78% of cases, the ultrasound and MRI results agreed and showed no abnormality. In 13%, ultrasound and MRI described identical abnormal findings. In 9%, the ultrasound and MRI examinations had discrepant findings; in all these cases the MRI findings described more serious CNS pathology. The effects on management were judged to be major, by at least one assessor, in 7/9 of those cases.

CONCLUSION

As in many other situations involving antenatal detection of CNS abnormalities, in utero MRI should be considered in females with increased risk of foetal CNS malformation based on the results of an earlier pregnancy. Advances in knowledge In utero MRI of the foetus has an important role in antenatal diagnosis of females carrying a foetus with an increased risk of a brain abnormality.

Decision influences and aftermath: parents, stillbirth and autopsy

BACKGROUND

Stillbirth, among the most distressing experiences an adult may face, is also a time when parents must decide whether an autopsy or other post-mortem examinations will be performed on their infant. Autopsies can reveal information that might help explain stillbirth, yet little is known about how people make this difficult decision.

OBJECTIVES

This study examines the influences on decisions about autopsy after stillbirth among Australian parents.

DESIGN

The study involved secondary analysis of transcripts of three focus groups using qualitative content analysis.

PARTICIPANTS AND SETTING

Seventeen parents of 14 stillborn babies participated in consultations around the revision of a perinatal mortality audit guideline.

RESULTS

Parents shared the decision making. Four decision drivers were identified: parents' preparedness or readiness to make decisions; parental responsibility; concern for possible consequences of an autopsy and the role of health professionals. Each decision driver involved reasons both for and against autopsy. Two decision aftermath were also present: some parents who agreed to an autopsy were dissatisfied with the way the autopsy results were given to them and some parents who did not have an autopsy for their infant expressed some form of regret or uncertainty about the choice they made.

CONCLUSIONS

To make decisions about autopsy after stillbirth, parents need factual information about autopsy procedures, recognition that there might be fear of blame, an environment of trust, and health services and professionals prepared and skilled for difficult conversations.

Parents' perceptions of their infants' participation in randomized controlled trials

OBJECTIVE

To explore parents' perceptions of their infants' participation in randomized control trials (RCTs) and the implications of the RCT for their infant and themselves.

DESIGN

A qualitative study using semistructured interviews.

SETTING

Participants were identified from neonatal intensive care unit (NICU) clinical registers and from responses to an advertisement put on the website of United Kingdom special care baby charity, BLISS. Interviews were conducted with parents face-to-face in their homes or over the telephone.

PARTICIPANTS

Sixteen parents of 12 infants born prematurely or with complications at full term and who had participated in one of three RCTs while receiving intensive care in one of seven NICUs.

METHODS

Interviews were audio-taped or digitally recorded, transcribed verbatim, and analyzed using systematic thematic analysis using WinMax qualitative software.

RESULTS

Five main themes emerged from the data. The themes were parents' immediate reactions to being approached about RCT enrollment, interactions between parents and clinicians upon the approach of enrollment and during the RCT, making the decision to enroll their infants, implications of the RCT for parents, and effects of the RCT on the infants.

CONCLUSIONS

Clinicians should be encouraged to approach parents about enrollment of their infants in clinical research given that parents reported mostly positive experiences related to this participation. However, appropriate measures should be taken to ensure that the individual needs of parents are being met throughout the entire research process from enrollment to follow-up.

Perinatal postmortems: what is important to parents and how do they decide?

BACKGROUND

Falling consent rates for postmortems, regardless of age of death, have been widely reported in recent years. The aim of this study was to explore parental attitudes to, and decision-making about, a perinatal postmortem after termination for fetal abnormality, late miscarriage, or stillbirth.

METHODS

A prospective self-completion questionnaire was given to 35 women and their partners. The participants had experienced second or third trimester pregnancy loss in a single fetal medicine and delivery unit in the United Kingdom and were making decisions about having a postmortem. They were asked to complete a questionnaire about their attitudes to, and expectations of, a perinatal postmortem.

RESULTS

Thirty-one questionnaires were received from parents of 17 babies (49% of those asked; 16 from mothers, 15 from fathers). Parents of nine babies (53%) said they would agree to a full postmortem, of three babies to a limited postmortem, and of four babies to an external examination only; one couple were undecided. The most important issues for the parents in this study that related to their decisions about a postmortem centered on the need for information, both for future planning and about what had happened. Moderately important issues related to altruism, which is, improving medical knowledge and helping other parents experiencing similar bereavement. Among the lowest scoring issues were potential barriers, such as concerns about cultural or religious acceptability of a postmortem, funeral delays, and what would happen to the baby's body.

CONCLUSIONS

Bereaved parents who participated in this study, where postmortem consent rates were relatively high, thought that their need for knowledge eclipsed assumed barriers when deciding whether or not to have a postmortem for their baby.

Parents' views of involvement in concurrent research with their neonates

It would be useful to researchers and bioethicists to know more about parents' decision processes and emotional state during the time they are deciding whether to enroll their infant in a clinical trial. The aim of this research study was to discover whether parents who had been previously asked to enroll their neonates in clinical trials would have found concurrent research about their decision-making overly burdensome. Twenty-seven parents of critically ill neonates who had been approached for their child's research participation in a clinical trial were asked what they believed about the potential burden or value of being interviewed during the time of research decision-making about their infant's participation. For this qualitative descriptive study, interviews were audio-recorded, transcribed, and analyzed using content analysis techniques. Participants considered concurrent research acceptable for them but potentially problematic for others. Theories of risk preferences and social comparison might explain these findings.

The BRACELET Study: surveys of mortality in UK neonatal and paediatric intensive care trials

Background

The subject of death and bereavement in the context of randomised controlled trials in neonatal or paediatric intensive care is under-researched. The objectives of this phase of the Bereavement and RAndomised ControlLEd Trials (BRACELET) Study were to determine trial activity in UK neonatal and paediatric intensive care (2002-06); numbers of deaths before hospital discharge; and variation in mortality across intensive care units and trials and to determine whether bereavement support policies were available within trials. These are essential prerequisites to considering the implications of future policies and practice subsequent to bereavement following a child's enrolment in a trial.

Methods

The units survey involved neonatal units providing level 2 or 3 care, and paediatric units providing level II care or above; the trials survey involved trials where allocation was randomized and interventions were delivered to intensive care patients, or to parents but designed to affect patient outcomes.

Results

Information was available from 191/220 (87%) neonatal units (149 level 2 or 3 care); and 28/32 (88%) paediatric units. 90/177 (51%) eligible responding units participated in one or more trial (76 neonatal, 14 paediatric) and 54 neonatal units and 6 paediatric units witnessed at least one death. 50 trials were identified (36 neonatal, 14 paediatric). 3,137 babies were enrolled in neonatal trials, 210 children in paediatric trials. Deaths ranged 0-278 (median [IQR interquartile range] 2 [1, 14.5]) per neonatal trial, 0-4 (median [IQR] 1 [0, 2.5]) per paediatric trial. 534 (16%) participants died post-enrolment: 522 (17%) in neonatal trials, 12 (6%) in paediatric trials. Trial participants ranged 1-236 (median [IQR] 21.5 [8, 39.8]) per neonatal unit, 1-53 (median [IQR] 11.5 [2.3, 33.8]) per paediatric unit. Deaths ranged 0-37 (median [IQR] 3.5 [0.3, 8.8]) per neonatal unit, 0-7 (median [IQR] 0.5 [0, 1.8]) per paediatric unit. Three trials had a formal policy for responding to bereavement.

Conclusions

A substantial number of deaths after trial enrolment were identified, distributed over many trials and units. Few trial teams had responses to bereavement in place. Those with the largest numbers of deaths might be best placed to collaborate in developing and assessing responses to bereavement.

Increasing the efficiency of autopsy reporting

CONTEXT

-When autopsy reports are delayed, clinicians and families do not receive information in a timely fashion.

OBJECTIVE

-Using lean principles derived from the Toyota Production System, we set out to streamline our autopsy reporting process.

DESIGN

-In a formal workshop setting, we identified the steps involved in producing an autopsy report, then sought to eliminate, abbreviate, or reschedule them into a more efficient format. We established intermediate deadlines for each case, taking care to make them visible; we initiated a weekly quality assurance review, giving attention to both scientific issues and approaching deadlines.

RESULTS

-By adopting a more standardized approach, eliminating redundancy, and improving the visibility of tasks, we improved the mean completion time of autopsy reports from 53 days (N = 47 cases) to 25 days (N = 47 cases). Previously, 17% of reports were completed by 30 days and 71% by 60 days; in the 15 months following initiation of the program, 72% of reports were completed by 30 days and 100% by 60 days. A follow-up survey of attending physicians revealed continuing appreciation for the autopsy and timely communication, with no perceived diminution in the quality of reports.

CONCLUSIONS

-This approach was of great benefit in our laboratory and may assist others in reducing the turnaround time of their autopsy reports. It may also benefit other areas of the laboratory.

Hospital Care for Parents After Perinatal Death

OBJECTIVE

To systematically review parent experiences with hospital care after perinatal death.

DATA SOURCES

An evaluation of more than 1,100 articles from 1966 to 2006 was performed to identify studies of fetal death in the second or third trimester and neonatal death in the first month of life.

METHODS OF STUDY SELECTION

Studies were limited to those that were in English, evaluated care in U.S. hospitals, and contained direct parent data or opinions.

TABULATION, INTEGRATION, AND RESULTS

Results were compiled on five aspects of recommended care: 1) obtaining photographs and memorabilia of the deceased infant, 2) seeing and holding the infant, 3) labor and delivery of the child, 4) autopsies, and 5) options for funerals or memorial services. Sixty eligible studies with over 6,200 patients were reviewed. In general, parents reported appreciating time and contact with their deceased infant, being given options about labor, delivery, and burial, receiving photographs and memorabilia, and having appropriate hospital follow-up after autopsy.

CONCLUSION

Although care after perinatal death often adheres to published guidelines, substantial room for improvement is apparent. Parents with perinatal losses report few choices during labor and delivery and inadequate communication about burial options and autopsy results. Hospitals, nurses, and doctors should increase parental choice about timing and location of delivery and postpartum care, encourage parental contact with the deceased infant, and facilitate provision of photos and memorabilia.

Equipoise: a case study of the views of clinicians involved in two neonatal trials

BACKGROUND

It is considered to be a fundamental ethical premise of human experimentation, that it should be carried out only where the effects of an intervention are unclear. The point at which it is considered that there is insufficient scientific and medical evidence to clearly state the superiority of an intervention has been termed equipoise. This concept has been the subject of much recent impassioned debate but little empirical research about the views of people involved in recruitment to randomized controlled trials (RCTs), and none in the particularly emotive area of neonatal intensive care.

METHODS

Thirty neonatologists recruiting into one or both of two neonatal RCTs in five centres in England were interviewed using a semi-structured schedule to explore their involvement in randomised trials. The interviews were tape-recorded and transcribed. Equipoise was one among a range of topics covered. Concepts relating to equipoise were identified by close reading of the entire interviews. Themes emerging from the data were noted in their contexts then discussed between the co-authors. Interviewees also completed a brief questionnaire about their demographic background, and their experience of research and RCTs.

RESULTS

Almost all the neonatologists used the concept of equipoise [using words and phrases such as uncertainty, lack of knowledge (or ignorance), strengths of views, and balancing of pros and cons] in their interview and, for most of them, equipoise seemed to be a useful term. They explored ideas about equipoise at the individual and community levels, and some linked equipoise with notions of the responsibility that should be exercised by the scientific and professional communities. They differed in the importance they gave to individual equipoise, and in how they reacted to threats to equipoise. Feelings of doubt about a trial and disturbed equipoise were more often expressed by more junior doctors.

CONCLUSIONS

Our findings suggest that the concept of equipoise goes beyond the idea of uncertainty. In part this is because it includes the balancing of benefit and harm; this balancing is part of a professional obligation and requires engagement with 'expert' knowledge. Equipoise could therefore be seen as 'active' or 'responsible' uncertainty. Elucidation of this difficult concept may help to facilitate recruitment for both clinicians and parents in future trials and thereby help to find answers to important clinical questions.

Post-mortem MRI of the foetal spine and spinal cord

AIMS

To compare the findings of post-mortem magnetic resonance imaging (MRI) of the foetal spine with autopsy with a view to using post-mortem MRI as an alternative or adjunct to autopsy, particularly in foetal and neonatal cases.

MATERIALS AND METHODS

The brains and spines of 41 foetuses, with a gestational age range of 14-41 weeks, underwent post-mortem MRI before autopsy. Post-mortem MRI of the brain consisted of T2-weighted sequences in three orthogonal planes and MRI of the spine consisted of T2-weighted sequence in the sagittal and axial planes in all cases and coronal planes in selected cases.

RESULTS

Thirty of 41 (78%) foetal spines were found to be normal at autopsy and on post-mortem MRI. Eleven of 41 (22%) foetal spines were abnormal: eight foetuses had myelomeningocoeles and Chiari 2 deformities, one foetus had limited dorsal myeloschisis, one foetus had caudal regression syndrome, and one had diastematomyelia. The post-mortem MRI findings concurred with the autopsy findings in 10/11 of the abnormal cases, the disagreement being the case of diastematomyelia that was shown on post-mortem MRI but was not diagnosed at autopsy.

CONCLUSIONS

In this series, post-mortem MRI findings agreed with the autopsy findings in 40/41(98%) cases and in one case the post-mortem MRI demonstrated an abnormality not demonstrated at autopsy.

"It was a snap decision": parental and professional perspectives on the speed of decisions about participation in perinatal randomised controlled trials

For some perinatal trials, parents can be asked to make important decisions about trial participation within limited timeframes in highly stressful circumstances. This qualitative study explores the pace of decision-making for 78 parents associated with one or more of four such trials in the UK. The themes associated with rapid decisions were concern for their baby, reactions to staff, and perceptions of the benefits and risks associated with the trial. Those who took longer to decide whether or not to participate often described similar emotions to those who made rapid decisions, but their slower decisions were because more time was available, they wanted further discussion or they found the decision particularly difficult. The majority of those who made rapid decisions felt that there were no risks associated with the trial in question, in contrast to the majority of those who made slower decisions who felt there were risks. The parents did not appear to view rapid decisions as problematic. Although there was evidence of parental vulnerability in each trial context, they largely felt that they acted swiftly and responsibly in the best interests of their child in accordance with the timeframes that were set for them.

Postmortem MR imaging of the fetus: an adjunct or a replacement for conventional autopsy?

Fetal and perinatal autopsy provides essential diagnostic information not only for parents but also for medical audit and clinical trials. The autopsy rate is decreasing throughout the world for numerous reasons. Medical imaging has always been part of the autopsy process, but in the last decade there has been increased interest in imaging as additional to or a replacement for autopsy. This is especially so with the wider availability of magnetic resonance (MR) scanners that are able to provide detailed anatomy of all body structures as well as having the potential to provide information about histopathological patterns of injury. Postmortem MR imaging (MRI) provides similar information to autopsy for gross pathology of most organ systems. It often provides more information in cases of central nervous system abnormalities, but is less accurate for cardiac abnormalities. Targeted, image-guided biopsy may allow histological diagnosis following postmortem MRI.

What factors are important to parents making decisions about neonatal research?

BACKGROUND

Although parents of neonates with congenital heart disease are often asked permission for their neonates to participate in research studies, little is known about the factors parents consider when making these decisions.

OBJECTIVE

To determine the reasons for parents' decisions about participation in research studies.

METHODS

Qualitative analysis of the unsolicited comments of 34 parents regarding reasons for agreeing or declining to participate in research studies. Parents' comments were offered spontaneously during interviews about clinical care decisions for neonates with congenital heart disease.

RESULTS

Parents cited five types of reason for or against permitting their newborn to participate in research studies: societal benefit (n = 18), individual benefit for their infant (n = 16), risk of study participation (n = 10), perception that participation posed no harm (n = 9), and anti-experimentation views (n = 4).

CONCLUSION

Addressing parental decision making in the light of these reasons could enhance the parental permission process for parents of critically ill neonates.

Post-mortem MRI as an adjunct to fetal or neonatal autopsy

CONTEXT

Understanding what was wrong with a dead fetus or why a newborn child died can help the parents to grieve, while any findings can be used to inform the parents if there is a risk to future pregnancies and the level of risk. This information is mainly obtained from autopsies, but the number of parents agreeing to autopsy has dropped, which has prompted the search for adjuncts to autopsy.

STARTING POINT

The UK's Chief Medical Officer outlined the rationale for exploring alternatives to autopsy in 2000 and 2001. After wide consultation, MRI was deemed to offer the most realistic chance of making a contribution. Results so far are promising, but of insufficient depth and quality to make firm recommendations about providing a service in the future. In 2004, the UK Department of Health therefore tendered for this research to be done in fetal and neonatal (and adult) cases, and this work is due to start in 2005. WHERE NEXT? High-quality anatomical information about the brain and spine of fetuses and neonates can be easily obtained with standard MRI scanners. Most developmental and acquired abnormalities can be seen on post-mortem MRI. More work needs to be done on organs not in the central nervous system, and heart malformations, in particular, might present diagnostic problems. A possible outcome could be whole-body MRI plus targeted biopsies of abnormalities taken under image guidance as an adjunct to formal autopsy.

Perinatal pathology in the context of a clinical trial: a review of the literature

Perinatal postmortem rates are declining world wide. In the United Kingdom, perinatal pathology has recently been seriously undermined by controversy. There are important consequences for perinatal trials that include pathology studies. This review looks at the reasons for the decline in perinatal postmortem examinations and the effects on research.

Perinatal pathology in the context of a clinical trial: attitudes of neonatologists and pathologists

OBJECTIVE

To describe the attitudes of neonatologists to trial related perinatal postmortem examinations (PMs), in the light of declining perinatal PM rates and poor levels of participation in pathology studies.

METHODS

A qualitative study was carried out, using semistructured interviews. Twenty six neonatologists from five UK neonatal units were interviewed; five UK perinatal pathologists also contributed to the study. The professionals involved were all linked to one or both of two neonatal trials.

RESULTS

Pathologists expressed concern over the difficulties experienced in UK perinatal pathology and the impact on research of inadequate levels of samples. The interviews with neonatologists reveal discomfort over approaching bereaved parents for PMs, and a widespread concern that parents should not be further distressed or feel under pressure to consent. Although there was support for neonatal trials, the study highlights a view that PMs may be unnecessary if the cause of death seems apparent or when a baby was born prematurely, and a devaluation of PMs among some younger staff. Poor rates of participation in pathology studies may be accounted for by a notable sense of disconnection between trial interventions and pathology studies.

CONCLUSIONS

Neonatologists were concerned to protect vulnerable parents and varied in whether they saw this as compatible with inclusion in trial related pathology studies. Dedicated research is needed to document and gain an understanding of the consent process and should examine the usefulness and impact of consent forms. It should assess whether professionals might benefit from training, to help parents to come to their decisions.
