The CDH patient perspective journey.

Background: Congenital Diaphragmatic Hernia is a malformation of the diaphragm resulting in ongoing clinical symptoms and problems. Mortality remains high, particularly where there are other issues involved. Tracking a patient throughout their lifetime to understand the full impact on health and function is challenging. CDH UK is a registered charity supporting anyone affected by CDH. It has over 25 years of experience and a broad range of patient experience and knowledge. Aims: To develop a patient journey with timepoints of significance. Methods: We studied our own data and looked at what we already knew from publications and medical advisors. We recruited a focus group, plotted out stages and timepoints through their "lived" experiences using the Team Idea Mapping method. We then compared these experiences to our own data, to identify the common issues in daily life and care. Outcome: We have developed a patient journey through the eyes of the patient and turned it into a patient friendly infographic. This can be used as a tool to help understand the CDH Journey throughout a patient's lifetime. CDH UK has already used this to create a first prototype of a mobile application. It has also further helped to recognize areas of patient concern and to improve services and resources. Discussion: This can be used as a basis for care and research, including standards, benchmarking, transition and helping improvements in healthcare, education, family life and social settings. Potentially holding clues as to the etiology and pathology of the condition and an opportunity to further explore theories and unanswered questions. It may help improve counselling and bereavement care, resulting in better general and mental health outcomes.

Patient-reported outcomes for congenital diaphragmatic hernia: A qualitative study.

OBJECTIVE: To identify Patient-reported outcomes (PROs) for parents with a lived experience of a prenatal diagnosis of isolated congenital diaphragmatic hernia (CDH). METHOD: Thematic analysis of in-depth interview transcripts. RESULTS: Interviews (n = 26) identified 11 PROs for given time points throughout the CDH trajectory. At the time of diagnosis, acceptable quality of life was selected as relevant PRO to decide whether to continue or terminate the pregnancy. During pregnancy, (neonatal) survival chances and the eligibility for foetal therapy were prominent outcomes with foetal and maternal complications adding distress. After birth, postnatal management options became the next milestone. When survival was deemed likely, post-hospital discharge complications and future care for infant and child became important. In retrospect, impact on family, bonding, parental mental health, and parental satisfaction with care were reported as relevant outcomes. CONCLUSION: PROs are relevant in addition to hard medical outcomes, as they help parents to make decisions suiting their unique needs and personal situation. Given the knowledge inherently related to the parent's perspective, our findings provide relevant directions for clinicians to support parents and their family in facing challenging decisions in healthcare. The outcomes impacting parents are essential to prepare parents for the steep journey ahead.

Prenatal diagnosis of congenital diaphragmatic hernia: Parental counselling and support needs.

OBJECTIVE: To define the dimensions of patient-centeredness of prenatal care for parents who had a fetus with isolated congenital diaphragmatic hernia (CDH) by exploring their values, experiences, needs and preferences. METHODS: In-depth interviews with parents who were faced with the prenatal diagnosis of isolated CDH. RESULTS: Interviews (n = 18) identified seven dimensions of patient-centeredness. Parental preferences are respected by unconditional acceptance of parental choices and needs. After diagnosis access to care should occur by swift referral to a specialised centre to prevent parents receiving contradictory information. Information and education help parents to gain some sense of control and cope with the many uncertainties. A multidisciplinary team with a coordinating professional is perceived supportive (coordination and integration), and seamless referral between local and treatment centres reduces parental distress (continuity and transition). Family-centred emotional support helps parents to cope with emotions and distress. Informal support by involvement of family and friends and trusted peer-support is of added value. CONCLUSION: The impact of the uncertainty of outcome in this condition is tremendous and needs to be considered when providing prenatal care. After initial diagnosis, one should avoid speculation about the severity of the condition and outcome, and provide swift referral to a specialist centre expert in managing CDH. Provision of realistic and comprehensive information helps parents cope. Multidisciplinary and continuous support throughout the full trajectory, but also integrated psychosocial support should become standard-of-care.

Development of standard definitions and grading for Maternal and Fetal Adverse Event Terminology.

OBJECTIVE: Adverse event (AE) monitoring is central to assessing therapeutic safety. The lack of a comprehensive framework to define and grade maternal and fetal AEs in pregnancy trials severely limits understanding risks in pregnant women. We created AE terminology to improve safety monitoring for developing pregnancy drugs, devices and interventions. METHOD: Existing severity grading for pregnant AEs and definitions/indicators of 'severe' and 'life-threatening' conditions relevant to maternal and fetal clinical trials were identified through a literature search. An international multidisciplinary group identified and filled gaps in definitions and severity grading using Medical Dictionary for Regulatory Activities (MedDRA) terms and severity grading criteria based on Common Terminology Criteria for Adverse Event (CTCAE) generic structure. The draft criteria underwent two rounds of a modified Delphi process with international fetal therapy, obstetric, neonatal, industry experts, patients and patient representatives. RESULTS: Fetal AEs were defined as being diagnosable in utero with potential to harm the fetus, and were integrated into MedDRA. AE severity was graded independently for the pregnant woman and her fetus. Maternal (n = 12) and fetal (n = 19) AE definitions and severity grading criteria were developed and ratified by consensus. CONCLUSIONS: This Maternal and Fetal AE Terminology version 1.0 allows systematic consistent AE assessment in pregnancy trials to improve safety.

What should we tell parents? Congenital diaphragmatic hernia.

Congenital diaphragmatic hernia (CDH) is characterized by a defect in the muscle dividing the thoracic and abdominal cavities. This leads to herniation of the abdominal organs into the thorax and a disturbance of lung development. Two-thirds of cases are identified by prenatal ultrasound in the second trimester, which should prompt referral to a tertiary center for prognosis assessment and counseling by a multidisciplinary team familiar with this condition. In this review, we summarize evidence on prenatal diagnosis and postnatal management of CDH. There is a focus on information that should be provided to expecting parents during prenatal counseling.

Surgical-PEARL protocol: a multicentre prospective cohort study exploring aetiology, management and outcomes for patients with congenital anomalies potentially requiring surgical intervention.

INTRODUCTION: Congenital anomalies affect over 2% of pregnancies. Surgical advances have reduced mortality and improved survival for patients with congenital anomalies potentially requiring surgical (CAPRS) intervention. However, our understanding of aetiology, diagnostic methods, optimal management, outcomes and prognostication is limited. Existing birth cohorts have low numbers of individual heterogenous CAPRS. The Surgical Paediatric congEnital Anomalies Registry with Long term follow-up (Surgical-PEARL) study aims to establish a multicentre prospective fetal, child and biological parent cohort of CAPRS. METHODS AND ANALYSIS: From 2022 to 2027, Surgical-PEARL aims to recruit 2500 patients with CAPRS alongside their biological mothers and fathers from up to 15 UK centres. Recruitment will be antenatal or postnatal dependent on diagnosis timing and presentation to a recruitment site. Routine clinical data including antenatal scans and records, neonatal intensive care unit (NICU) records, diagnostic and surgical data and hospital episode statistics will be collected. A detailed biobank of samples will include: parents' blood and urine samples; amniotic fluid if available; children's blood and urine samples on admission to NICU, perioperatively or if the child has care withdrawn or is transferred for extracorporeal membrane oxygenation; stool samples; and surplus surgical tissue. Parents will complete questionnaires including sociodemographic and health data. Follow-up outcome and questionnaire data will be collected for 5 years. Once established we will explore the potential of comparing findings in Surgical-PEARL to general population cohorts born in the same years and centres. ETHICS AND DISSEMINATION: Ethical and health research authority approvals have been granted (IRAS Project ID: 302251; REC reference number 22/SS/0004). Surgical-PEARL is adopted onto the National Institute for Health Research Clinical Research Network portfolio. Findings will be disseminated widely through peer-reviewed publication, conference presentations and through patient organisations and newsletters. TRIAL REGISTRATION NUMBER: ISRCTN12557586.

Study protocol: a core outcome set for perinatal interventions for congenital diaphragmatic hernia.

BACKGROUND: Congenital diaphragmatic hernia (CDH) is, depending of the severity, a birth defect associated with significant mortality and morbidity. Prenatal screening by ultrasound may detect this condition and comprehensive assessment of severity is possible, allowing for in utero referral to an experienced centre for planned delivery. In an effort to improve outcomes, prenatal interventions to stimulate lung development were proposed. Along the same lines, new postnatal management strategies are being developed. In order to enable proper comparison of novel perinatal interventions as well as outcomes, a set of uniform and relevant outcome measures is required. Core outcome sets (COS) are agreed, clearly defined sets of outcomes to be measured in a standardised manner and reported consistently. Herein we aim to describe the methodology we will use to define a COS for perinatal and neonatal outcomes of foetuses and newborns with congenital diaphragmatic hernia and to draft a dissemination and implementation plan. METHODS: We will use the methodology described in the Core Outcome Measures in Effectiveness Trials (COMET) Initiative Handbook. An international steering group will be created to guide the development of the COS. We are systematically reviewing the literature to identify all potential relevant pre- and neonatal outcomes previously used in studies on perinatal interventions for CDH. We will build a consensus on these core outcomes in a stakeholder group using the Delphi method. After completion, a stakeholder meeting will decide on a final COS, using a modified Nominal Group Technique. Thereafter, we will review potential definitions and measurements of these outcomes, and again a consensus meeting will be organised, to finalise the COS before dissemination. DISCUSSION: We have started a procedure to develop a COS for studies on perinatal interventions for congenital diaphragmatic hernia, with the purpose of improving the quality of research, guide clinical practice and improve patient care and eventual use in future clinical trials, systematic reviews and clinical practice guidelines. TRIAL REGISTRATION: We prospectively registered this study in the International Prospective Register of Systematic Reviews (PROSPERO) (registration number: CRD42019124399 ) and The Core Outcome Measures in Effectiveness Trials (COMET) Initiative (registration number: 1296 ).

Long-term feeding issue and its impact on the daily life of congenital diaphragmatic hernia survivors: results of the first patient-led survey.

BACKGROUND: CDH UK is a registered charity governed by a volunteer committee and providing informal support to patients, families and healthcare workers affected directly or indirectly with congenital diaphragmatic hernia (CDH) internationally. This is the first patient-led survey undertaken by CDH UK aiming for highlighting the feeding problems and their impact on the daily life of CDH survivors. METHODS: Answers from CDH survivors were collected through an online questionnaire (SurveyMonkey®) undertaken by CDH UK. The questionnaire contained questions about their feeding problems and support they were receiving for it. MAIN RESULTS: Overall, 151 patients answered some parts of the survey and 102 patients completed the questionnaire. Overall, 116 (76.8%) responders reported suffering from any type of feeding issue. Gastric acid reflux (GER) and growth retardation were the commonest symptoms experienced by 97 (91.5%) and 72 (62.2%) responders, respectively. Only 18 (17.0%) responders have received any written information on feeding or details of patient/parent support. Eighty (75.5%) responders are satisfied with the level of support they are receiving, but 78 (76.4%) answered that the whole experience associated with the disease has been very or extremely stressful. CONCLUSIONS: CDH survivors frequently have various issues with feeding, which may not be adequately supported or discussed clinically. It is desirable to assist the patients to reliable resources of long-term support, including multidisciplinary team (MDT) approach.

Does website-based information add any value in counseling mothers expecting a baby with severe congenital diaphragmatic hernia?

OBJECTIVE: We aimed to measure whether website-provided information about congenital diaphragmatic hernia (CDH) and fetal therapy for severe cases provides added value compared with clinical counseling of parents. METHODS: This is a single center study in 102 couples who earlier opted for fetoscopic endoluminal tracheal occlusion (FETO) because of isolated severe CDH. They were asked to fill out an anonymized web-based survey of 12 questions. Then, they were offered access to information on the web pages of the randomized Tracheal Occlusion to Accelerate Lung Growth (TOTAL) trial. One week later, their appreciation was measured again by a second questionnaire. RESULTS: Eighty-two (80%) parents completed the first questionnaire, and 48 (47%) completed the entire survey. Several items became more clear to the parents after reading the website, such as the length of hospital stay (23.2% prior to web information, 60.4% after; P = 0.004), maternal risk, or the requirement of fetal anesthesia for FETO (43.9% resp. 79.2%; P = <0.001). CONCLUSION: Complementing prenatal counseling on CDH and FETO by standardized information via website is perceived by parents as of added value. Maternal risks and the need for fetal medication need more clarification during the verbal counseling prior to prenatal interventions.
