RESUMO

The purpose of this European Society for Radiotherapy and Oncology (ESTRO) project, endorsed by the European Association of Urology, is to explore expert opinion on the management of patients with oligometastatic and oligoprogressive renal cell carcinoma by means of stereotactic ablative radiotherapy (SABR) on extracranial metastases, with the aim of developing consensus recommendations for patient selection, treatment doses, and concurrent systemic therapy. A questionnaire on SABR in oligometastatic renal cell carcinoma was prepared by a core group and reviewed by a panel of ten prominent experts in the field. The Delphi consensus methodology was applied, sending three rounds of questionnaires to clinicians identified as key opinion leaders in the field. At the end of the third round, participants were able to find consensus on eight of the 37 questions. Specifically, panellists agreed to apply no restrictions regarding age (25 [100%) of 25) and primary renal cell carcinoma histology (23 [92%] of 25) for SABR candidates, on the upper threshold of three lesions to offer ablative treatment in patients with oligoprogression, and on the concomitant administration of immune checkpoint inhibitor. SABR was indicated as the treatment modality of choice for renal cell carcinoma bone oligometatasis (20 [80%] of 25) and for adrenal oligometastases 22 (88%). No consensus or major agreement was reached regarding the appropriate schedule, but the majority of the poll (54%-58%) retained the every-other-day schedule as the optimal choice for all the investigated sites. The current ESTRO Delphi consensus might provide useful direction for the application of SABR in oligometastatic renal cell carcinoma and highlight the key areas of ongoing debate, perhaps directing future research efforts to close knowledge gaps.

RESUMO

Diamond-Blackfan anaemia (DBA), first described over 80 years ago, is a congenital disorder of erythropoiesis with a predilection for birth defects and cancer. Despite scientific advances, this chronic, debilitating, and life-limiting disorder continues to cause a substantial physical, psychological, and financial toll on patients and their families. The highly complex medical needs of affected patients require specialised expertise and multidisciplinary care. However, gaps remain in effectively bridging scientific discoveries to clinical practice and disseminating the latest knowledge and best practices to providers. Following the publication of the first international consensus in 2008, advances in our understanding of the genetics, natural history, and clinical management of DBA have strongly supported the need for new consensus recommendations. In 2014 in Freiburg, Germany, a panel of 53 experts including clinicians, diagnosticians, and researchers from 27 countries convened. With support from patient advocates, the panel met repeatedly over subsequent years, engaging in ongoing discussions. These meetings led to the development of new consensus recommendations in 2024, replacing the previous guidelines. To account for the diverse phenotypes including presentation without anaemia, the panel agreed to adopt the term DBA syndrome. We propose new simplified diagnostic criteria, describe the genetics of DBA syndrome and its phenocopies, and introduce major changes in therapeutic standards. These changes include lowering the prednisone maintenance dose to maximum 0·3 mg/kg per day, raising the pre-transfusion haemoglobin to 9-10 g/dL independent of age, recommending early aggressive chelation, broadening indications for haematopoietic stem-cell transplantation, and recommending systematic clinical surveillance including early colorectal cancer screening. In summary, the current practice guidelines standardise the diagnostics, treatment, and long-term surveillance of patients with DBA syndrome of all ages worldwide.

RESUMO

BACKGROUND: A variety of definitions for a clinical near-complete response after neoadjuvant (chemo) radiotherapy for rectal cancer are currently used. This variety leads to inconsistency in clinical practice, long-term outcome, and trial enrollment. OBJECTIVE: The aim of this study was to reach expert-based consensus on the definition of a clinical near-complete response after (chemo) radiotherapy. DESIGN: A modified Delphi process, including a systematic review, 3 surveys, and 2 meetings, was performed with an international expert panel consisting of 7 surgeons and 4 radiologists. The surveys consisted of individual features, statements, and feature combinations (endoscopy, T2-weighted MRI, and diffusion-weighted MRI). SETTING: The modified Delphi process was performed in an online setting; all 3 surveys were completed online by the expert panel, and both meetings were hosted online. MAIN OUTCOME MEASURES: The main outcome was to reach consensus (80% or more agreement). RESULTS: The expert panel reached consensus on a 3-tier categorization of the near-complete response category based on the likelihood of the response to evolve into a clinical complete response after a longer waiting interval. The panelists agreed that a near-complete response is a temporary entity only to be used in the first 6 months after (chemo)radiotherapy. Furthermore, consensus was reached that the lymph node status should be considered when deciding on a near-complete response and that biopsies are not always needed when a near-complete response is found. No consensus was reached on whether primary staging characteristics have to be taken into account when deciding on a near-complete response. LIMITATIONS: This 3-tier subcategorization is expert-based; therefore, there is no supporting evidence for this subcategorization. Also, it is unclear whether this subcategorization can be generalized into clinical practice. CONCLUSIONS: Consensus was reached on the use of a 3-tier categorization of a near-complete response, which can be helpful in daily practice as guidance for treatment and to inform patients with a near-complete response on the likelihood of successful organ preservation. See Video Abstract. UN CONSENSO INTERNACIONAL BASADO EN EXPERTOS ACERCA DE LA DEFINICIN DE UNA RESPUESTA CLNICA CASI COMPLETA DESPUS DE QUIMIORADIOTERAPIA NEOADYUVANTE CONTRA EL CNCER DE RECTO: ANTECEDENTES:Actualmente, se utilizan una variedad de definiciones para una respuesta clínica casi completa después de quimioradioterapia neoadyuvante contra el cáncer de recto. Esta variedad resulta en inconsistencia en la práctica clínica, los resultados a largo plazo y la inscripción en ensayos.OBJETIVO:El objetivo de este estudio fue llegar a un consenso de expertos sobre la definición de una respuesta clínica casi completa después de quimioradioterapia.DISEÑO:Se realizó un proceso Delphi modificado que incluyó una revisión sistemática, 3 encuestas y 2 reuniones con un panel internacional de expertos compuesto por siete cirujanos y 4 radiólogos. Las encuestas consistieron en características individuales, declaraciones y combinaciones de características (endoscopía, T2W-MRI y DWI).AJUSTE:El proceso Delphi modificado se realizó en un entorno en línea; el panel de expertos completó las tres encuestas en línea y ambas reuniones se realizaron en línea.PRINCIPALES MEDIDAS DE RESULTADO:El resultado principal fue llegar a un consenso (≥80% de acuerdo).RESULTADOS:El panel de expertos llegó a un consenso sobre una categorización de tres niveles de la categoría de respuesta casi completa basada en la probabilidad de que la respuesta evolucione hacia una respuesta clínica completa después de un intervalo de espera más largo. Los panelistas coincidieron en que una respuesta casi completa es una entidad temporal que sólo debe utilizarse en los primeros 6 meses después de la quimioradioterapia. Además, se llegó a un consenso en que se debe considerar el estado de los nódulos linfáticos al decidir sobre una respuesta casi completa y que no siempre se necesitan biopsias cuando se encuentra una respuesta casi completa. No se llegó a un consenso sobre si se deben tener en cuenta las características primarias de estadificación al decidir una respuesta casi completa.LIMITACIONES:Esta subcategorización de 3 niveles está basada en expertos; por lo tanto, no hay evidencia que respalde esta subcategorización. Además, no está claro si esta subcategorización puede generalizarse a la práctica clínica.CONCLUSIONES:Se alcanzó consenso sobre el uso de una categorización de 3 niveles de una respuesta casi completa que puede ser útil en la práctica diaria como guía para el tratamiento y para informar a los pacientes con una respuesta casi completa sobre la probabilidad de una preservación exitosa del órgano.

RESUMO

BACKGROUND: Digital approaches may be helpful in augmenting care to address unmet mental health needs, particularly for schizophrenia and severe mental illness (SMI). OBJECTIVE: An international multidisciplinary group was convened to reach a consensus on the challenges and potential solutions regarding collecting data, delivering treatment, and the ethical challenges in digital mental health approaches for schizophrenia and SMI. METHODS: The consensus development panel method was used, with an in-person meeting of 2 groups: the expert group and the panel. Membership was multidisciplinary including those with lived experience, with equal participation at all stages and coproduction of the consensus outputs and summary. Relevant literature was shared in advance of the meeting, and a systematic search of the recent literature on digital mental health interventions for schizophrenia and psychosis was completed to ensure that the panel was informed before the meeting with the expert group. RESULTS: Four broad areas of challenge and proposed solutions were identified: (1) user involvement for real coproduction; (2) new approaches to methodology in digital mental health, including agreed standards, data sharing, measuring harms, prevention strategies, and mechanistic research; (3) regulation and funding issues; and (4) implementation in real-world settings (including multidisciplinary collaboration, training, augmenting existing service provision, and social and population-focused approaches). Examples are provided with more detail on human-centered research design, lived experience perspectives, and biomedical ethics in digital mental health approaches for SMI. CONCLUSIONS: The group agreed by consensus on a number of recommendations: (1) a new and improved approach to digital mental health research (with agreed reporting standards, data sharing, and shared protocols), (2) equal emphasis on social and population research as well as biological and psychological approaches, (3) meaningful collaborations across varied disciplines that have previously not worked closely together, (4) increased focus on the business model and product with planning and new funding structures across the whole development pathway, (5) increased focus and reporting on ethical issues and potential harms, and (6) organizational changes to allow for true communication and coproduction with those with lived experience of SMI. This study approach, combining an international expert meeting with patient and public involvement and engagement throughout the process, consensus methodology, discussion, and publication, is a helpful way to identify directions for future research and clinical implementation in rapidly evolving areas and can be combined with measurements of real-world clinical impact over time. Similar initiatives will be helpful in other areas of digital mental health and similarly fast-evolving fields to focus research and organizational change and effect improved real-world clinical implementation.

RESUMO

INTRODUCTION: Influenza is a serious underestimated viral infection in Pakistan and influenza vaccination and vaccination awareness are low. The current work aimed to develop consensus on influenza epidemiology, prevention, vaccination, and awareness in Pakistan. METHODOLOGY: A systematic literature search was conducted to develop recommendations on influenza vaccines in Pakistan. Experts' feedback was incorporated using the modified Delphi method. A three-step process was used, with 18 experts from different specialties from Pakistan who participated in voting rounds to achieve a minimum 75% agreement level. RESULTS: Pakistan has a low-immunization-rate and is susceptible to serious influenza outbreaks and influenza-related complications. Influenza circulates year-round in Pakistan but peaks during January and February. The subtype A/H1N1 is predominant. The experts urged vaccination in all individuals ≥ 6 months of age and with no contraindications. They highlighted special considerations for those with comorbidities and specific conditions. The experts agreed that the inactivated influenza vaccine is safe and efficient in pregnant women, immunocompromised, and comorbid respiratory and cardiovascular patients. Finally, the experts recommended conducting promotional and educational programs to raise awareness on influenza and vaccination. CONCLUSIONS: This is the first regional consensus on influenza and influenza vaccination in Pakistan with experts' recommendations to increase influenza vaccination and decrease influenza cases and its associated detrimental effects.

RESUMO

Osteoporotic fracture is the most serious complication of osteoporosis, which is a special type of pathologic fracture of the skeleton that occurs because of osteoporosis. It is characterized by delayed fracture healing, high risk of re-fracture, high rate of disability and death, difficulty in treatment and long treatment time, and re-fracture has a"cascade effect". Guidelines in different countries recommend that patients with osteoporotic fractures and those at very high risk of fracture should consider anabolic agents as first treatment choice. Teriparatide is the only anabolic agent approved by National Medical Products Administration (NMPA), and it has the clinical efficacy of improving fracture healing, reducing the risk of re-fracture, and improving bone microstructure in the treatment of osteoporotic fracture. Due to deficiencies in the current standardization of clinical use of teriparatide, Committee of Accelerated Rehabilitation After Osteoporotic Fractures of China Association of Rehabilitation Technology Transformation and Promotion, Bone and Joint Group of Chinese Society of Osteoporosis and Bone Mineral Research and Osteoporosis Working Committee of Chinese Association of Orthopedic Surgeons developed this consensus. The development of this consensus follows the modified Delphi method and forms 8 evidence-based medical recommendations, aiming to propose methods and precautions for standardizing the application of teriparatide, and to emphasize the importance of teriparatide application for the treatment of patients with osteoporotic fracture.

RESUMO

Chronic thromboembolic pulmonary hypertension (CTEPH) is classified as group IV pulmonary hypertension, characterized by thrombotic occlusion of the pulmonary arteries leading to vascular stenosis or obstruction, progressive increase in pulmonary vascular resistance and pulmonary arterial pressure, and eventual right heart failure. Unlike other types of pulmonary hypertension, the prognosis of CTEPH can be significantly improved by surgery, vascular intervention, and/or targeted drug therapy. Pulmonary endarterectomy (PEA) is the preferred treatment of choice for CTEPH. However, PEA is an invasive procedure with high operative risks, and is currently only performed in a few centers in China. Balloon pulmonary angioplasty (BPA) is an emerging interventional technique for CTEPH, serving as an alternative for patients who are ineligible for PEA or with residual pulmonary hypertension after PEA. BPA is gaining traction in China, but its widespread adoption is limited due to its complexity, operator skills, and equipment requirements, a lack of standard operating procedures and technical guidance, which limit the further improvement and development of BPA in China. To address this, a multidisciplinary panel of experts was convened to develop the Consensus on the Procedure of Balloon Pulmonary Angioplasty for the Chronic Thromboembolic Pulmonary Hypertension, which fomulates guidelines on BPA procedural qualification, perioperative management, procedural planning, technical approach, and complication prevention, with the aim of providing recommendations and clinical guidance for BPA treatment in CTEPH and standardizing its clinical application in this setting. Summary of recommendations: Recommendation 1: It is recommended that physicians who specialize in pulmonary vascular diseases take the lead in formulating the diagnostic and treatment plans for CTEPH, using a multidisciplinary approach.Recommendation 2: Training in BPA technique is critical; novice operators should undergo standardized operative training with at least 50 procedures under the guidance of experienced physicians before embarking on independent BPA procedures.Recommendation 3: BPA requires catheterization labs, angiography systems, standard vascular interventional devices and consumables, drugs, and emergency equipment.Recommendation 4: Patient selection for BPA should consider cardiac and pulmonary function, coagulation status, and comorbid conditions to determine indications and contraindications, thereby optimizing the timing of the procedure and improving safety.Recommendation 5: In experienced centers, patients deemed likely to benefit from early BPA, based on clinical and imaging features of CTEPH and without elevated D-dimer levels, could bypass standard 3-month anticoagulation therapy.Recommendation 6: BPA is a complex interventional treatment that requires thorough pre-operative assessment and preparation.Recommendation 7: The use of perioperative anticoagulants in BPA requires a comprehensive risk assessment of intraoperative bleeding by the operator for individualized decision making.Recommendation 8: A variety of venous access routes are available for BPA; unless contraindicated, the right femoral vein is usually preferred because of its procedural convenience and reduced radiation exposure.Recommendation 9: For the different types of vascular lesion in CTEPH, treatment of ring-like stenoses, web-like lesions, and subtotal occlusions should be prioritized before addressing complete occlusions and tortuous lesions, in order to reduce complications and improve procedural safety.Recommendation 10: A targeted, incremental balloon dilatation strategy based on vascular lesions is recommended for BPA.Recommendation 11: Intravascular pulmonary artery imaging technologies, such as OCT and IVUS can assist in accurate vessel sizing and confirmation of wire placement in the true vascular lumen. Pressure wires can be used to objectively assess the efficacy of dilatation during BPA.Recommendation 12: Endpoints for BPA treatment should be individually assessed, taking into account improvements in clinical symptoms, hemodynamics, exercise tolerance, and quality of life.Recommendation 13: Post-BPA routine monitoring of vital signs is essential; anticoagulation therapy should be initiated promptly post-procedure in the absence of complications. In cases of intraoperative hemoptysis, postoperative anticoagulation regimen adjustments should be adjusted according to the bleeding severity.Recommendation 14: If reperfusion pulmonary edema occurs during or after BPA, ensure adequate oxygenation, diuresis, and consider non-invasive positive-pressure ventilation if necessary, while severe cases may require early mechanical ventilation assistance or ECMO.Recommendation 15: In cases of intraoperative hemoptysis, temporary balloon occlusion to stop bleeding is recommended, along with protamine to neutralize heparin. Persistent bleeding may warrant the use of gelatin sponges, coil embolization, or covered stent implantation.Recommendation 16: For contrast imaging during BPA, non-ionic, low or iso-osmolar contrast agents are recommended, with hydration status determined by the patient's clinical condition, cardiac and renal function, and intraoperative contrast volume used.

RESUMO

BACKGROUND: Nurses work at headache centres throughout Europe, and their care for migraine patients is acknowledged. However, the specific roles and tasks of nursing vary, and a unified understanding is lacking, posing challenges to knowledge sharing and research. OBJECTIVES: Using an e-Delphi study method, the objective is to obtain healthcare professional headache experts' opinions on nursing-specific roles and tasks and combine this into consensus statements for nurse recommendations for migraine treatment. METHODS: A three-round questionnaire study was conducted with nurses and neurologists from 18 specialised headache centres in 10 countries. In round 1, statements were compiled from a systematic examination of existing literature and expert opinions. In rounds 2 and 3, the experts rated the importance of statements (from round 1) on a 5-point Likert scale. Statements were analysed using a content analysis method, and the consensus of pre-defined statements was evaluated with gradually increased predetermined criteria using descriptive statistics. RESULTS: Twenty-one experts, representing all 10 countries, participated. The predetermined consensus of ≥70% agreement was reached for 42 out of the initial 63 statements. These statements formed the final recommendations within two themes: "The nurses' roles and tasks in the clinical setting" and "The nurses' roles and tasks in educating patients and colleagues." The consensus level of statements was strong, with 40% receiving unanimous agreement (100%) and 97% achieving relatively high agreement (>80%). CONCLUSION: Nursing plays a vital role with diverse tasks in migraine care. This study offers practical recommendations and a framework for nurses, equipping them with a clinical tool to enhance care and promote a coordinated approach to migraine treatment.

RESUMO

The evolution of critical care medicine is inextricably linked to the development of critical care procedures. These procedures not only facilitate diagnosis and treatment of critically ill patients, but also provide valuable insights into disease pathophysiology. While critical care interventions offer undeniable benefits, the potential for iatrogenic complications necessitates careful consideration. The recent surge in critical care ultrasound (US) utilization is a testament to its unique advantages: non-invasiveness, real-time bedside availability, direct visualization of internal structures, elimination of ionizing radiation exposure, repeatability, and relative ease of learning. Recognizing the need to optimize procedures and minimize complications, critical care utrasound study group of Beijing critical care ultrasound research assocition convened a panel of critical care experts to generate this consensus statement. This document serves as a guide for healthcare providers, aiming to ensure patient safety and best practices in critical care.

RESUMO

PURPOSE: To identify elements of timely integration of palliative care (PC) into hospital oncology care from best practices. Thereafter, to assess the level of consensus among oncology and PC specialists and patient and relative representatives on the characteristics of timely integration of PC. METHODS: A three-round modified Delphi study was conducted. The expert panel consisted of 83 healthcare professionals (HCPs) from 21 Dutch hospitals (43 physicians, 40 nurses), 6 patient and 2 relative representatives. In the first round, four elements of integrated PC were considered: (1) identification of potential PC needs, (2) advance care planning (ACP), (3) routine symptom monitoring and (4) involvement of the specialist palliative care team (SPCT). In subsequent rounds, the panellists assessed which characteristics were triggers for initiating an element. A priori consensus was set at ≥ 70%. RESULTS: A total of 71 (78%) panellists completed the first questionnaire, 65 (71%) the second and 49 (54%) the third. Panellists agreed that all patients with incurable cancer should have their PC needs assessed (97%), symptoms monitored (91%) and ACP initiated (86%). The SPCT should be involved at the patient's request (86%) or when patients suffer from increased symptom burden on multiple dimensions (76%). Patients with a life expectancy of less than 3 months should be offered a consultation (71%). CONCLUSION: The expert panel agreed that timely integration of PC into oncology is important for all patients with incurable cancer, using early identification, ACP and routine symptom monitoring. Involvement of the SPCT is particularly needed in patients with multidimensional symptom burden and in those nearing death.

RESUMO

The identification and management of patients at high bleeding risk (HBR) undergoing transcatheter aortic valve implantation (TAVI) are of major importance, but the lack of standardised definitions is challenging for trial design, data interpretation, and clinical decision-making. The Valve Academic Research Consortium for High Bleeding Risk (VARC-HBR) is a collaboration among leading research organisations, regulatory authorities, and physician-scientists from Europe, the USA, and Asia, with a major focus on TAVI-related bleeding. VARC-HBR is an initiative of the CERC (Cardiovascular European Research Center), aiming to develop a consensus definition of TAVI patients at HBR, based on a systematic review of the available evidence, to provide consistency for future clinical trials, clinical decision-making, and regulatory review. This document represents the first pragmatic approach to a consistent definition of HBR evaluating the safety and effectiveness of procedures, devices and drug regimens for patients undergoing TAVI..

RESUMO

Conversation is a primary means of social influence, but its effects on brain activity remain unknown. Previous work on conversation and social influence has emphasized public compliance, largely setting private beliefs aside. Here, we show that consensus-building conversation aligns future brain activity within groups, with alignment persisting through novel experiences participants did not discuss. Participants watched ambiguous movie clips during fMRI scanning, then conversed in groups with the goal of coming to a consensus about each clip's narrative. After conversation, participants' brains were scanned while viewing the clips again, along with novel clips from the same movies. Groups that reached consensus showed greater similarity of brain activity after conversation. Participants perceived as having high social status spoke more and signaled disbelief in others, and their groups had unequal turn-taking and lower neural alignment. By contrast, participants with central positions in their real-world social networks encouraged others to speak, facilitating greater group neural alignment. Socially central participants were also more likely to become neurally aligned to others in their groups.

RESUMO

INTRODUCTION: The term primary progressive aphasia (PPA) describes a group of language-led dementias. Disease-modifying treatments that delay, slow or reverse progression of PPA are currently lacking, though a number of interventions to manage the symptoms of PPA have been developed in recent years. Unfortunately, studies exploring the effectiveness of these interventions have used a variety of different outcome measures, limiting comparability. There are more constructs, apart from word retrieval, that are important for people with PPA that have not received much attention in the research literature. Existing core outcome sets (COS) for dementia and non-progressive aphasia do not meet the needs of people with PPA, highlighting a need to develop a specific COS for PPA. METHODS AND ANALYSIS: This protocol describes a three-stage study to identify a COS for PPA interventions in research and clinical practice. The stage 1 systematic review will identify existing speech, language and communication measures used to examine the effectiveness of interventions for PPA in the research literature. Employing a nominal group technique, stage 2 will identify the most important outcomes for people with PPA and their families. The data collected in stages 1 and 2 will be jointly analysed with the project PPI group and will inform the stage 2 modified Delphi consensus study to identify a core outcome measurement set for PPA among a range of research disciplines undertaking intervention studies for people with PPA. ETHICS AND DISSEMINATION: Ethical approval for stage 2 of the study has been sought individually in each country at collaborating institutions and is stated in detail in the manuscript. Stage 3 has been granted ethical approval by the Chairs of UCL Language and Cognition Department Ethics, Project ID LCD-2023-06. Work undertaken at stages 1, 2 and 3 will be published in open-access peer-reviewed journal articles and presented at international scientific conferences.

RESUMO

OBJECTIVE: There are no globally agreed on strategies on early detection and first response management of postpartum haemorrhage (PPH) during and after caesarean birth. Our study aimed to develop an international expert's consensus on evidence-based approaches for early detection and obstetric first response management of PPH intraoperatively and postoperatively in caesarean birth. DESIGN: Systematic review and three-stage modified Delphi expert consensus. SETTING: International. POPULATION: Panel of 22 global experts in PPH with diverse backgrounds, and gender, professional and geographic balance. OUTCOME MEASURES: Agreement or disagreement on strategies for early detection and first response management of PPH at caesarean birth. RESULTS: Experts agreed that the same PPH definition should apply to both vaginal and caesarean birth. For the intraoperative phase, the experts agreed that early detection should be accomplished via quantitative blood loss measurement, complemented by monitoring the woman's haemodynamic status; and that first response should be triggered once the woman loses at least 500 mL of blood with continued bleeding or when she exhibits clinical signs of haemodynamic instability, whichever occurs first. For the first response, experts agreed on immediate administration of uterotonics and tranexamic acid, examination to determine aetiology and rapid initiation of cause-specific responses. In the postoperative phase, the experts agreed that caesarean birth-related PPH should be detected primarily via frequently monitoring the woman's haemodynamic status and clinical signs and symptoms of internal bleeding, supplemented by cumulative blood loss assessment performed quantitatively or by visual estimation. Postoperative first response was determined to require an individualised approach. CONCLUSION: These agreed on proposed approaches could help improve the detection of PPH in the intraoperative and postoperative phases of caesarean birth and the first response management of intraoperative PPH. Determining how best to implement these strategies is a critical next step.

RESUMO

INTRODUCTION: Patient engagement and integrated knowledge translation (iKT) processes improve health outcomes and care experiences through meaningful partnerships in consensus-building initiatives and research. Consensus-building is essential for engaging a diverse group of experienced knowledge users in co-developing and supporting a solution where none readily exists or is less optimal. Patients and caregivers provide invaluable insights for building consensus in decision-making around healthcare, policy and research. However, despite emerging evidence, patient engagement remains sparse within consensus-building initiatives. Specifically, our research has identified a lack of opportunity for youth living with chronic health conditions and their caregivers to participate in developing consensus on indicators/benchmarks for transition into adult care. To bridge this gap and inform our consensus-building approach with youth/caregivers, this scoping review will synthesise the extent of the literature on patient and other knowledge user engagement in consensus-building healthcare initiatives. METHODS AND ANALYSIS: Following the scoping review methodology from Joanna Briggs Institute, published literature will be searched in MEDLINE, EMBASE, CINAHL and PsycINFO databases from inception to July 2023. Grey literature will be hand-searched. Two independent reviewers will determine the eligibility of articles in a two-stage process, with disagreements resolved by a third reviewer. Included studies must be consensus-building studies within the healthcare context that involve patient engagement strategies. Data from eligible studies will be extracted and charted on a standardised form. Abstracted data will be analysed quantitatively and descriptively, according to specific consensus methodologies, and patient engagement models and/or strategies. ETHICS AND DISSEMINATION: Ethics approval is not required for this scoping review protocol. The review process and findings will be shared with and informed by relevant knowledge users. Dissemination of findings will also include peer-reviewed publications and conference presentations. The results will offer new insights for supporting patient engagement in consensus-building healthcare initiatives. PROTOCOL REGISTRATION: https://osf.io/beqjr.

RESUMO

OBJECTIVE: Delineate the scope of teleconsultation services that can be effectively performed to provide women with comprehensive gynaecological and obstetrical care. DESIGN: Based on the literature and experts' insights, we identified a list of gynaecological and obstetrical care practices suitable for teleconsultation. A three-round Delphi consensus survey was then conducted online among a panel of French experts. Experts using a 9-point Likert scale assessed the relevance of each teleconsultation practice in four key domains: prevention, gynaecology and antenatal and postnatal care. Consensus was determined by applying a dual-criteria approach: the median score on a 9-point Likert scale and the percentage of votes either below 5 or 5 and higher. SETTING: The study was conducted at a national level in France and involved multiple healthcare centres and professionals from various geographical locations. PARTICIPANTS: The panel comprised 22 French experts with 19 healthcare professionals, including 12 midwives, 3 obstetricians-gynaecologists, 4 general practitioners and 3 healthcare system users. Participants were selected to include diverse practice settings encompassing hospital and private practices in both rural and urban areas. PRIMARY AND SECONDARY OUTCOME MEASURES: The study's primary outcome was the identification of gynaecological and obstetrical care practices suitable for teleconsultation. Secondary outcomes included the level of professional consensus on these practices. RESULTS: In total, 71 practices were included in the Delphi survey. The practices approved for teleconsultation were distributed as follows: 92% in prevention (n=12/13), 55% in gynaecology (n=18/33), 31% in prenatal care (n=5/16) and 12% in postnatal care (n=1/9). Lastly, 10 practices remained under discussion: 7 in gynaecology, 2 in prenatal care and 1 in postnatal care. CONCLUSIONS: Our consensus survey highlights both the advantages and limitations of teleconsultations for women's gynaecological and obstetrical care, emphasising the need for careful consideration and tailored implementation.

RESUMO

Perinatal mental illness is an important public health issue, with one in five birthing persons experiencing clinically significant symptoms of anxiety and/or depression during pregnancy or the postpartum period. The purpose of this study was to develop a consensus-based model of integrated perinatal mental health care to enhance service delivery and improve parent and family outcomes. We conducted a three-round Delphi study using online surveys to reach consensus (≥75% agreement) on key domains and indicators of integrated perinatal mental health care. We invited modifications to indicators and domains during each round and shared a summary of results with participants following rounds one and two. Descriptive statistics were generated for quantitative data and a thematic analysis of qualitative data was undertaken. Study participants included professional experts in perinatal mental health (e.g., clinicians, researchers) (n = 36) and people with lived experience of perinatal mental illness within the past 5 years from across Canada (e.g., patients, family members) (n = 11). Consensus was reached and all nine domains of the proposed model for integrated perinatal mental health care were retained. Qualitative results informed the modification of indicators and development of an additional domain and indicators capturing the need for antiracist, culturally safe care. The development of an integrated model of perinatal mental health benefitted from diverse expertise to guide the focus of included domains and indicators. Engaging in a consensus-building process helps to create the conditions for change within health services.
