Imaging Stewardship: Triage for Neuroradiology MR During Limited-Resource Hours

OBJECTIVES

To decrease call burden on pediatric neuroradiologists, we developed guidelines for appropriate use of MR overnight. These guidelines were implemented using triage by in-house generalist pediatric radiologists. Process measures and balancing measures were assessed during implementation.

METHODS

For this improvement project, interdepartmental consensus guidelines were developed using exploratory mixed-methods design. Implementation of triage used plan-do-study-act cycles. Process measures included reduction in the number of telephone calls, frequency of calls, triage decisions, and number and type of examinations ordered. Balancing measures included burden of time and effort to the generalist radiologists. Differences in examination orders between implementation intervals was assessed using Kruskal-Wallis, with significance at P < .05.

RESULTS

Consensus defined MR requests as "do," "defer," or "divert" (to CT). Guidelines decreased neuroradiologist calls 74% while adding minimal burden to the generalist radiologists. Most nights had zero or one triage request and the most common triage decision was "do," and the most common examination was routine brain MR. Number of MR ordered and completed overnight did not significantly change with triage.

DISCUSSION

Multidisciplinary consensus for use of pediatric neurological MR during limited resource hours overnight is an example of imaging stewardship that decreased the burden of calls and burnout for neuroradiologists while maintaining a comparable level of service to the ordering clinicians.

The American Brachytherapy Society and Indian Brachytherapy Society consensus statement for the establishment of high-dose-rate brachytherapy programs for gynecological malignancies in low- and middle-income countries

PURPOSE

The global cervical cancer burden is disproportionately high in low- and middle-income countries (LMICs), and outcomes can be governed by the accessibility of appropriate screening and treatment. High-dose-rate (HDR) brachytherapy plays a central role in cervical cancer treatment, improving local control and overall survival. The American Brachytherapy Society (ABS) and Indian Brachytherapy Society (IBS) collaborated to provide this succinct consensus statement guiding the establishment of brachytherapy programs for gynecological malignancies in resource-limited settings.

METHODS AND MATERIALS

ABS and IBS members with expertise in brachytherapy formulated this consensus statement based on their collective clinical experience in LMICs with varying levels of resources.

RESULTS

The ABS and IBS strongly encourage the establishment of HDR brachytherapy programs for the treatment of gynecological malignancies. With the consideration of resource variability in LMICs, we present 15 minimum component requirements for the establishment of such programs. Guidance on these components, including discussion of what is considered to be essential and what is considered to be optimal, is provided.

CONCLUSIONS

This ABS/IBS consensus statement can guide the successful and safe establishment of HDR brachytherapy programs for gynecological malignancies in LMICs with varying levels of resources.

Consensus-based guidelines for the provision of palliative and end-of-life care for people living with epidermolysis bullosa

BACKGROUND

Inherited epidermolysis bullosa (EB) is a cluster of rare, genetic skin and mucosal fragility disorders with multi-system and secondary effects, in which blistering and erosions occur in response to friction/mechanical trauma. Considering the incurable and potentially life-limiting nature of the condition and the challenges posed by its symptoms, a palliative approach to EB-related care is necessary. However, knowledge and experience related to the provision of EB palliative care is minimal. Evidence-based, best care guidelines are needed to establish a base of knowledge for practitioners to prevent or ease suffering while improving comfort at all stages of the illness, not just the end of life.

METHODS

This consensus guideline (CG) was begun at the request of DEBRA International, an international organization dedicated to improvement of care, research, and dissemination of knowledge for EB patients, and represents the work of an international panel of medical experts in palliative care and EB, people living with EB, and people who provide care for individuals living with EB. Following a rigorous, evidence-based guideline development process, the author panel identified six clinical outcomes based on the results of a survey of people living with EB, carers, and medical experts in the field, as well as an exhaustive and systematic evaluation of literature. Recommendations for the best clinical provision of palliative care for people living with EB for each of the outcomes were reached through panel consensus of the available literature.

RESULTS

This article presents evidence-based recommendations for the provision of palliative healthcare services that establishes a base of knowledge and practice for an interdisciplinary team approach to ease suffering and improve the quality of life for all people living with EB. Any specific differences in the provision of care between EB subtypes are noted.

CONCLUSIONS

Because there is yet no cure for EB, this evidence-based CG is a means of optimizing and standardizing the IDT care needed to reduce suffering while improving comfort and overall quality of life for people living with this rare and often devastating condition.

Target volume delineation for radiotherapy of meningiomas: an ANOCEF consensus guideline

PURPOSE

Radiotherapy is, with surgery, one of the main therapeutic treatment strategies for meningiomas. No prospective study has defined a consensus for the delineation of target volumes for meningioma radiotherapy. Therefore, target volume definition is mainly based on information from retrospective studies that include heterogeneous patient populations. The aim is to describe delineation guidelines for meningioma radiotherapy as an adjuvant or definitive treatment with intensity-modulated radiation therapy and stereotactic radiation therapy techniques. This guideline is based on a consensus endorsed by a multidisciplinary group of brain tumor experts, members of the Association of French-speaking Neuro-oncologists (ANOCEF).

MATERIALS AND METHODS

A 3-step procedure was used. First, the steering group carried out a comprehensive review to identify divergent issues on meningiomas target volume delineation. Second, an 84-item web-questionnaire has been developed to precisely define meningioma target volume delineation in the most common clinical situations. Third, experts members of the ANOCEF were requested to answer. The first two rounds were completed online. A third round was carried out by videoconference to allow experts to debate and discuss the remaining uncertain questions. All questions remained in a consensus.

RESULTS

Limits of the target volume were defined using visible landmarks on computed tomography and magnetic resonance imaging, considering the pathways of tumor extension. The purpose was to develop clear and precise recommendations on meningiomas target volumes.

CONCLUSION

New recommendations for meningiomas delineation based on simple anatomic boundaries are proposed by the ANOCEF. Improvement in uniformity in target volume definition is expected.

Taiwanese dermatological association (TDA) consensus for the management of pemphigus

Pemphigus is an uncommon but life-threatening autoimmune blistering disease characterized by the presence of antibodies against desmogleins. Without effective treatment, pemphigus can result in significant morbidity and mortality. Existing consensus statements on pemphigus management from international medical groups provide varying guidelines, especially on treatment. Thus, on January 4, 2020, a panel of seven dermatology experts from the Taiwanese Dermatological Association (TDA) and one rheumatology expert convened to develop a consensus for the management of pemphigus. These experts with extensive experience in pemphigus management were recommended by their respective teaching hospitals and primary care clinics in Taiwan and by the TDA. The meeting reviewed the available consensus statements from international dermatology groups, including the European Dermatology Forum (EDF), the European Academy of Dermatology and Venereology (EADV), and the International Bullous Diseases Consensus Group. Using these guidelines as a basis for discussion and consensus formulation, these experts formulated their consensus statement that provides practical, concise but comprehensive recommendations as to the diagnosis, treatment, and monitoring of pemphigus patients in Taiwan. This consensus serves as a clinical reference for physicians for the management of pemphigus in Taiwan or wherever it may be applicable.

Asymptomatic Microscopic Hematuria in Inpatient Nonsurgical Adults

OBJECTIVES

This study sought to determine the proportion of nonsurgical inpatients with asymptomatic microscopic hematuria (AMH) who qualified for urologic investigation according to consensus guidelines.

METHODS

The study population included all patients acutely admitted to the internal medicine departments of Israeli regional hospitals between 2014 and 2017.

RESULTS

Of 29,086 consecutive admissions, 10,116 (34.8%) underwent dipstick urinalysis and 8,389 (28.8%) underwent reflex microscopic urinalysis. After the exclusion of patients with a urethral catheter or a positive urine culture, 2,206 had 3 or more RBCs per high-power field, and as many as 2,052 (7.1% of the entire cohort and 24.4% of all patients undergoing microscopic urinalysis) met the criteria for a urologic workup.

CONCLUSIONS

We conclude that according to the consensus guidelines, an unreasonably high proportion of hospitalized nonsurgical patients would be referred for a urologic workup of uncertain clinical utility because of an incidental AMH finding.

Management of Diabetic Macular Edema: Guidelines from the Emirates Society of Ophthalmology

In the United Arab Emirates, retinopathy has been shown to be present in 19% of the diabetic population, with diabetes identified in up to 40% of individuals aged over 55 years. Despite the prevalence of diabetic retinal diseases, there are no unified national guidelines on the management of diabetic macular edema (DME). These published guidelines are based on evidence taken from the literature and published trials of therapies, and consensus opinion of a representative expert panel with an interest in this condition, convened by the Emirates Society of Ophthalmology. The aim is to provide evidence-based, clinical guidance for the best management of different aspects of DME, with a special focus on vision-threatening diabetic retinopathy. Treatment should be initiated in patients with best-corrected visual acuity 20/30 or worse, and/or features of DME as seen on optical coherence tomography (OCT) with central retinal thickness (CRT) of at least 300 μm or in symptomatic patients with vision better than 20/25, and/or CRT less than 300 μm where there are OCT features consistent with center-involving macular edema. The treatment of DME is effective irrespective of glycated hemoglobin (HbA1c) level, and treatment must not be denied or delayed in order to optimize systemic parameters. All ophthalmic treatment options should be discussed with the patient for better compliance and expectations. Non-center-involving DME can be initially observed until progression toward the center is documented. Macular laser no longer has a primary role in center-involving DME, and anti-vascular endothelial growth factor (anti-VEGF) therapy should be considered as first-line treatment for all patients, unless contraindicated. If anti-VEGF is contraindicated, a steroid dexamethasone implant can be considered for first-line treatment. Recommendations for the treatment of DME in special circumstances and in relapsing and refractory DME are also discussed.

Spectrum of germline pathogenic variants using a targeted next generation sequencing panel and genotype-phenotype correlations in patients with suspected hereditary breast cancer at an academic medical centre in Pakistan

Background

Breast cancer is the most common malignancy in women, affecting over 1.5 million women every year, which accounts for the highest number of cancer-related deaths in women globally.

Hereditary breast cancer (HBC), an important subset of breast cancer, accounts for 5–10% of total cases. However, in Low Middle-Income Countries (LMICs), the population-specific risk of HBC in different ethnicities and the correlation with certain clinical characteristics remain unexplored.

Methods

Retrospective chart review of patients who visited the HBC clinic and proceeded with multi-gene panel testing from May 2017 to April 2020.

Descriptive and inferential statistics were used to analyze clinical characteristics of patients. Fisher’s exact, Pearson’s chi-squared tests and Logistic regression analysis were used for categorical variables and Wilcoxon rank-sum test were used for quantitative variables. For comparison between two independent groups, Mann-Whitney test was performed. Results were considered significant at a p value of < 0.05.

Results

Out of 273 patients, 22% tested positive, 37% had a VUS and 41% had a negative genetic test result. Fifty-five percent of the positive patients had pathogenic variants in either BRCA1 or BRCA2, while the remaining positive results were attributed to other genes. Patients with a positive result had a younger age at diagnosis compared to those having a VUS and a negative result; median age 37.5 years, IQR (Interquartile range) (31.5–48). Additionally, patients with triple negative breast cancer (TNBC) were almost 3 times more likely to have a positive result (OR = 2.79, CI = 1.42–5.48 p = 0.003). Of all patients with positive results, 25% of patients had a negative family history of breast and/or related cancers.

Conclusions

In our HBC clinic, we observed that our rate of positive results is comparable, yet at the higher end of the range which is reported in other populations. The importance of expanded, multi-gene panel testing is highlighted by the fact that almost half of the patients had pathogenic or likely pathogenic variants in genes other than BRCA1/2, and that our test positivity rate would have only been 12.8% if only BRCA1/2 testing was done. As the database expands and protocol-driven referrals are made across the country, our insight about the genetic architecture of HBC in our population will continue to increase.

New Zealand experience with implementation of the ESO-ESMO consensus guidelines for advanced breast cancer-report of achievements and lessons learned

BACKGROUND

People with advanced breast cancer (ABC) in New Zealand (NZ) have a poorer five-year survival than their peers in other developed countries. Comparisons of ABC care in NZ with other countries suggest that NZ is sometimes out of line with international standards and that inequities exist within the NZ healthcare system. Our aim was to develop nationwide consensus guidelines for diagnosis and treatment of ABC that are uniquely suited for the NZ context and can be applied across the nation. We describe the process of creating, voting on, and disseminating the guidelines, and provide insight into how we can better optimize these processes for the NZ context in the future.

METHODS

The ABC5 ESO-ESMO consensus guidelines were used and adapted to the NZ clinical context. A panel of breast cancer clinicians voted on these guidelines using the same model of membership representation as ABC5.

OUTCOME

Overall consensus was equally high between ABC5 and ABC-NZ. Four NZ specific guidelines were introduced. The European-style panel discussion needs some adaptations for the NZ situation and a wider and more thorough consultation process, before voting begins, is preferred. The NZ Breast Special Interest Group has endorsed and agreed to take ownership of these and future guidelines and to facilitate the next iteration of the ABC-NZ guidelines meeting.

CONCLUSIONS

The process was successful in creating the guidelines but can be improved in future meetings to streamline the process of creating and updating guidelines in the manner most suited to the NZ context and audience.

GEC-ESTRO ACROP prostate brachytherapy guidelines

This is an evidence-based guideline for prostate brachytherapy. Throughout levels of evidence quoted are those from the Oxford Centre for Evidence based Medicine (https://www.cebm.ox.ac.uk/resources/levels-of-evidence/oxford-centre-for-evidence-based-medicine-levels-of-evidence-march-2009). Prostate interstitial brachytherapy using either permanent or temporary implantation is an established and evolving treatment technique for non-metastatic prostate cancer. Permanent brachytherapy uses Low Dose Rate (LDR) sources, most commonly I-125, emitting photon radiation over months. Temporary brachytherapy involves first placing catheters within the prostate and, on confirmation of accurate positioning, temporarily introducing the radioactive source, generally High Dose Rate (HDR) radioactive sources of Ir-192 or less commonly Co-60. Pulsed dose rate (PDR) brachytherapy has also been used for prostate cancer [1] but few centres have adopted this approach. Previous GEC ESTRO recommendations have considered LDR and HDR separately [2-4] but as there is considerable overlap, this paper provides updated guidance for both treatment techniques. Prostate brachytherapy allows safe radiation dose escalation beyond that achieved using external beam radiotherapy alone as it has greater conformity around the prostate, sparing surrounding rectum, bladder, and penile bulb. In addition there are fewer issues with changes in prostate position during treatment delivery. Systematic review and randomised trials using both techniques as boost treatments demonstrate improved PSA control when compared to external beam radiotherapy alone [5-7].

THE PROCESS OF DEVELOPING CONSENSUS GUIDELINES BY DENTAL ONCOLOGISTS FOR PRE-RADIOTHERAPY DENTAL CARE IN HEAD AND NECK CANCER PATIENTS USING THE MODIFIED DELPHI TECHNIQUE

BACKGROUND

There is a range of pre-radiation therapy (RT) dental care strategies used to prevent the side effects associated with the use of RT in the treatment of head and neck cancer. However, there is a paucity of evidence-based, prospectively tested clinical practice guidelines for dentists to utilize in the provision of care prior to RT.

PURPOSE

The aim of this study is to describe the process of creating consensus guidelines for dental care in head and neck cancer patients undergoing RT using the Modified Delphi Technique.

PROCEDURE

We invited 44 dental oncologists to participate as panelists in the study. Three rounds of iterative structured surveys were completed within eight months, followed by a virtual meeting to conclude the modified Delphi process. Questions were divided into six main domains and patients were categorized as low, moderate, and high-risk based on factors identified by panelists and agreed upon during the first round. The threshold value set for each round of the Delphi process was a 70% response rate and 75% Consensus level.

FINDINGS

Eighteen panelists out of the forty-four (41% overall response rate) completed the study. The number of questions that achieved the set consensus level in rounds 1,2,3 and the virtual meeting were 24%, 62%,61% and 81%, respectively. A confidence level of 95% and a response rate of >75% were reached throughout the process.

CONCLUSION

Consensus was attained in most of the questions in all domains, which will be utilized to develop guidelines for dental care in head and neck cancer patients before the commencement of RT.

Prioritizing cervical cancer screening services during the COVID-19 pandemic: Response of an academic medical center and a public safety net hospital in California

The expeditious diagnosis and treatment of high-grade cervical precancers are fundamental to cervical cancer prevention. However, during the COVID-19 pandemic healthcare systems have at times restricted in-person visits to those deemed urgent. Professional societies provided some guidance to clinicians regarding ways in which traditional cervical cancer screening might be modified, but many gaps remained. To address these gaps, leaders of screening programs at an academic medical center and an urban safety net hospital in California formed a rapid-action committee to provide guidance to its practitioners. Patients were divided into 6 categories corresponding to various stages in the screening process and ranked by risk of underlying high-grade cervical precancer and cancer. Tiers corresponding to the intensity of the local pandemic were constructed, and clinical delays were lengthened for the lowest-risk patients as tiers escalated. The final product was a management grid designed to escalate and de-escalate with changes in the local epidemiology of the COVID-19 pandemic. While this effort resulted in substantial delays in clinical screening services as mandated by the healthcare systems, the population effects of delaying on both cervical cancer outcomes as well as the beneficial effects related to decreasing transmission of severe acute respiratory coronavirus 2 have yet to be elucidated.

Incidental Adrenal Masses: Adherence to Guidelines and Methods to Improve Initial Follow-Up, A Systematic Review

OBJECTIVE

Incidental adrenal masses (IAMs) are detected in approximately 1%-2% of abdominal computed tomography (CT) scans. Recent estimates suggest that more than 70-million relevant CT scans are performed annually in the United States; thus, IAMs represent a significant clinical entity. Most clinical guidelines recommend an initial follow-up evaluation that includes imaging and biochemical testing after index IAM detection.

METHODS

Systematic review of literature in the PubMed, EMBASE and Web of Science databases to determine whether guidelines regarding IAM evaluation are followed and to identify effective management strategies. Our initial search was in January 2018 and updated in November, 2019.

RESULTS

31 studies met inclusion criteria. In most institutions, only a minority of patients with IAMs undergo initial follow-up imaging (median 34%, IQR 20%-50%) or biochemical testing (median 18%, IQR 15%-28%). 2 interventions shown to improve IAM evaluation are IAM-specific recommendations in radiology reports and dedicated multi-disciplinary teams. Interventions focused solely on alerting the ordering clinician or primary care provider to the presence of an IAM have not demonstrated effectiveness. Patients who are referred to an endocrinologist are more likely to have a complete IAM evaluation, but few are referred.

DISCUSSION

Most patients with an IAM do not have an initial evaluation. The radiology report has been identified as a key component in determining whether IAMs are evaluated appropriately. Care teams dedicated to management of incidental radiographic findings also improve IAM follow-up. Although the evidence base is sparse, these interventions may be a starting point for further inquiry into optimizing care in this common clinical scenario.

Pulmonary embolism and deep vein thrombosis: Similar but different

INTRODUCTION

Pulmonary embolism (PE) and deep vein thrombosis (DVT), the two clinical manifestations of venous thromboembolism (VTE), constitute a major global burden of cardiovascular disease. They are often referred to as one disease but several patient characteristics, risk factors, real-world treatment, and clinical outcomes may differ substantially between PE and DVT alone.

MATERIALS AND METHODS

We conducted a narrative review of the state-of-the-art literature on the topic of PE and DVT alone using PubMed, Google scholar, and MEDLINE databases and the most established international consensus statement guidelines for the management of VTE, focusing on the recommendations for diagnosis and treatment but also including epidemiological and clinical characteristics of VTE, highlighting similarities and differences between PE and DVT alone.

RESULTS

Several patient characteristics, risk factors, clinical manifestations, and outcomes differ substantially between PE versus DVT alone. Nevertheless, recommendations for both diagnosis and treatment are strikingly similar in the current guidelines for the management of DVT and PE, except for the indication for advanced reperfusion therapies.

CONCLUSIONS

The differences in risk factors, clinical manifestations, and clinical outcomes between patients with PE versus DVT alone are only marginally addressed in the current consensus guidelines. More data is needed allowing proposal of evidence-based adjustments in the diagnostic and therapeutic strategies for these two manifestations of VTE. Tailored risk stratification and individualized management strategies for patients with PE and DVT alone may lead to a better prognosis, less recurrence and complications, and possibly to a gain of quality-adjusted life years in patients with VTE.

Patient-centered Opioid Prescribing: Breaking Away From One-Size-Fits-All Prescribing Guidelines

BACKGROUND

Procedure-based opioid-prescribing guidelines have reduced the amount of opioids prescribed after surgery; however, many patients are still overprescribed opioids. The 24-h predischarge opioid consumption (PDOC) metric has been proposed to guide patient-centered prescribing.

MATERIALS AND METHODS

This is a single-institution, retrospective study of patients who underwent major abdominal surgery. We assessed the correlation between inpatient opioid use and discharge prescriptions using morphine milligram equivalents (MMEs). The adequacy of discharge prescriptions for individual patients was assessed using 2 models, one assuming constant opioid use (based on 24-h PDOC) and the other assuming a linear taper.

RESULTS

Of 596 included patients, gastric bypass and colectomy were the most common operations. Median length of stay was 3.5 d. Inpatient opioid use and discharge prescriptions were weakly correlated (r = 0.35). Patients with no opioid use 24 h before discharge (n = 133, 22.3%) were frequently discharged with opioid prescriptions. Patients with high opioid use (24-h PDOC >60 MME) were often discharged with prescriptions that would have lasted <48 h (164/200, 82%). Assuming constant opioid use, discharge prescriptions would have lasted patients a median of 5.1 d. With linear opioid tapering, 440 (72.9%) patients would have had leftover pills. A theoretical discharge prescription of 4 times 24-h PDOC would reduce the median prescription by 130 MMEs and allow a linear taper for 97.6% of patients.

CONCLUSIONS

At our institution, opioid prescribing was rarely patient-centered, with little correlation between patient's inpatient opioid use and discharge prescriptions. This leads to overprescribing for most patients and underprescribing for others.

2020 Korean Consensus Guidelines for Diagnosis and Treatment of Chronic Hand Eczema

Background

Hand eczema refers to eczema located on the hands, regardless of its etiology or morphology. Despite its high prevalence and significant impact on patients' quality of life, treatment is frequently challenging because of its heterogeneity, chronic and recurrent course, and lack of well-organized randomized controlled trials of the various treatment options.

Objective

These consensus guidelines aim to provide evidence-based recommendations on the diagnosis and management of hand eczema to improve patient care by helping physicians make more efficient and transparent decisions.

Methods

A modified Delphi method, comprising two rounds of email questionnaires with face-to-face meetings in between, was adopted for the consensus process that took place between February and September 2020. Forty experts in the field of skin allergy and contact dermatitis were invited to participate in the expert panel.

Results

Consensus was reached for the domains of classification, diagnostic evaluation, and treatment; and a therapeutic ladder to manage chronic hand eczema was developed.

Conclusion

These are the first consensus guidelines for chronic hand eczema in the Asian population, which will help standardize care and assist clinical decision-making in the diagnosis and treatment of chronic hand eczema.

Consensus guidelines for botulinum toxin therapy: general algorithms and dosing tables for dystonia and spasticity

Botulinum toxin (BT) therapy is a complex and highly individualised therapy defined by treatment algorithms and injection schemes describing its target muscles and their dosing. Various consensus guidelines have tried to standardise and to improve BT therapy. We wanted to update and improve consensus guidelines by: (1) Acknowledging recent advances of treatment algorithms. (2) Basing dosing tables on statistical analyses of real-life treatment data of 1831 BT injections in 36 different target muscles in 420 dystonia patients and 1593 BT injections in 31 different target muscles in 240 spasticity patients. (3) Providing more detailed dosing data including typical doses, dose variabilities, and dosing limits. (4) Including total doses and target muscle selections for typical clinical entities thus adapting dosing to different aetiologies and pathophysiologies. (5) In addition, providing a brief and concise review of the clinical entity treated together with general principles of its BT therapy. For this, we collaborated with IAB—Interdisciplinary Working Group for Movement Disorders which invited an international panel of experts for the support.

UK consensus recommendations on the management of oral epithelial dysplasia during COVID-19 pandemic outbreaks

OBJECTIVES

Oral Epithelial Dysplasia (OED) is associated with an increased risk of oral cancer development. The SARS-CoV-2 pandemic is necessitating the suspension or dramatic reduction of face-to-face non-urgent elective services, including OED clinics. Little is known regarding the potential impact of elective services suspension upon the risk of OED progression, and whether alternative strategies (e.g. remote consultations) may be introduced to ensure OED surveillance. The aim of this paper is to provide expert-opinion consensus recommendations for the management of OED during the current and future pandemic outbreaks.

MATERIALS AND METHODS

A working group of nine UK-based senior clinicians and academics in Oral and Maxillofacial Surgery and Oral Medicine was created and twelve consensus statements were developed using a modified-Delphi process. Greater than 80% agreement was considered a consensus.

RESULTS

Consensus was achieved for all twelve statements (89-100% agreement). The group agreed that, during the temporary suspension of elective services associated with COVID-19 pandemic outbreaks, patients with OED can be risk stratified to determine the length of accepted delay in face-to-face consultation. Remote consultations with patient-provided clinical photographs may be a useful way of maintaining a level of surveillance in this group of patients.

CONCLUSIONS

Using an expert working group methodology, we have developed consensus recommendations for the monitoring of individuals with OED during pandemic outbreaks associated with temporary suspension of elective services. This has identified areas of future research and highlighted the need for a stronger evidence base to inform the set-up and delivery of surveillance regimens for patients with OED.

ESTRO ACROP guideline for target volume delineation of skull base tumors

BACKGROUND AND PURPOSE

For skull base tumors, target definition is the key to safe high-dose treatments because surrounding normal tissues are very sensitive to radiation. In the present work we established a joint ESTRO ACROP guideline for the target volume definition of skull base tumors.

MATERIAL AND METHODS

A comprehensive literature search was conducted in PubMed using various combinations of the following medical subjects headings (MeSH) and free-text words: "radiation therapy" or "stereotactic radiosurgery" or "proton therapy" or "particle beam therapy" and "skull base neoplasms" "pituitary neoplasms", "meningioma", "craniopharyngioma", "chordoma", "chondrosarcoma", "acoustic neuroma/vestibular schwannoma", "organs at risk", "gross tumor volume", "clinical tumor volume", "planning tumor volume", "target volume", "target delineation", "dose constraints". The ACROP committee identified sixteen European experts in close interaction with the ESTRO clinical committee who analyzed and discussed the body of evidence concerning target delineation.

RESULTS

All experts agree that magnetic resonance (MR) images with high three-dimensional spatial accuracy and tissue-contrast definition, both T2-weighted and volumetric T1-weighted sequences, are required to improve target delineation. In detail, several key issues were identified and discussed: i) radiation techniques and immobilization, ii) imaging techniques and target delineation, and iii) technical aspects of radiation treatments including planning techniques and dose-fractionation schedules. Specific target delineation issues with regard to different skull base tumors, including pituitary adenomas, meningiomas, craniopharyngiomas, acoustic neuromas, chordomas and chondrosarcomas are presented.

CONCLUSIONS

This ESTRO ACROP guideline achieved detailed recommendations on target volume definition for skull base tumors, as well as comprehensive advice about imaging modalities and radiation techniques.

On the consensus nomenclature rules for radiopharmaceutical chemistry - Reconsideration of radiochemical conversion

Radiochemical conversion is an important term to be included in the "Consensus nomenclature rules for radiopharmaceutical chemistry". Radiochemical conversion should be used to define reaction efficiency by measuring the transformation of components in a crude reaction mixture at a given time, whereas radiochemical yield is better suited to define the efficiency of an entire reaction process including, for example, separation, isolation, filtration, and formulation.

Guidelines for the content and format of PET brain data in publications and archives: A consensus paper

It is a growing concern that outcomes of neuroimaging studies often cannot be replicated. To counteract this, the magnetic resonance (MR) neuroimaging community has promoted acquisition standards and created data sharing platforms, based on a consensus on how to organize and share MR neuroimaging data. Here, we take a similar approach to positron emission tomography (PET) data. To facilitate comparison of findings across studies, we first recommend publication standards for tracer characteristics, image acquisition, image preprocessing, and outcome estimation for PET neuroimaging data. The co-authors of this paper, representing more than 25 PET centers worldwide, voted to classify information as mandatory, recommended, or optional. Second, we describe a framework to facilitate data archiving and data sharing within and across centers. Because of the high cost of PET neuroimaging studies, sample sizes tend to be small and relatively few sites worldwide have the required multidisciplinary expertise to properly conduct and analyze PET studies. Data sharing will make it easier to combine datasets from different centers to achieve larger sample sizes and stronger statistical power to test hypotheses. The combining of datasets from different centers may be enhanced by adoption of a common set of best practices in data acquisition and analysis.

Consensus guideline for the diagnosis and treatment of tetrahydrobiopterin (BH4) deficiencies

BACKGROUND

Tetrahydrobiopterin (BH4) deficiencies comprise a group of six rare neurometabolic disorders characterized by insufficient synthesis of the monoamine neurotransmitters dopamine and serotonin due to a disturbance of BH4 biosynthesis or recycling. Hyperphenylalaninemia (HPA) is the first diagnostic hallmark for most BH4 deficiencies, apart from autosomal dominant guanosine triphosphate cyclohydrolase I deficiency and sepiapterin reductase deficiency. Early supplementation of neurotransmitter precursors and where appropriate, treatment of HPA results in significant improvement of motor and cognitive function. Management approaches differ across the world and therefore these guidelines have been developed aiming to harmonize and optimize patient care. Representatives of the International Working Group on Neurotransmitter related Disorders (iNTD) developed the guidelines according to the SIGN (Scottish Intercollegiate Guidelines Network) methodology by evaluating all available evidence for the diagnosis and treatment of BH4 deficiencies.

CONCLUSION

Although the total body of evidence in the literature was mainly rated as low or very low, these consensus guidelines will help to harmonize clinical practice and to standardize and improve care for BH4 deficient patients.

ISNO consensus guidelines for practical adaptation of the WHO 2016 classification of adult diffuse gliomas

Introduction

Recent advances in the molecular biology of adult diffuse gliomas have brought about a paradigm shift in their diagnostic criteria, as witnessed in the World Health Organization (WHO) 2016 guidelines for central nervous system tumors. It is now mandatory to perform several molecular tests to reach a definitive integrated diagnosis in most of the cases. This comes with additional cost and higher turnaround time, which is not always affordable in developing countries like India. In addition, the non-uniform distribution of advanced research and diagnostic testing centers adds to the difficulty.

Methods

The Indian Society of Neuro-oncology (ISNO) multidisciplinary expert panel consisting of neuropathologists, neurosurgeons, and radiation/medical oncologists convened to prepare the national consensus guidelines for approach to diagnosis of adult diffuse gliomas.

Results

Algorithms for arriving at an integrated diagnosis of adult diffuse gliomas predominantly using immunohistochemistry and with minimum possible additional molecular testing were agreed upon, thus addressing the problems of cost, accessibility, and turnaround time. Mandatory and optional tests were proposed for each case scenario.

Conclusion

This document represents the consensus of the various neuro-oncology disciplines involved in diagnosis and management of patients with adult diffuse gliomas. The article reflects a practical adaptation of the WHO recommendations to suit a resource constrained setup.

Pathogenesis and management of fracture-related infection

BACKGROUND

Both fracture-related infections (FRIs) and periprosthetic joint infections (PJIs) include orthopaedic implant-associated infections. However, key aspects of management differ due to the bone and soft tissue damage in FRIs and the option of removing the implant after fracture healing. In contrast to PJIs, research and guidelines for diagnosis and treatment in FRIs are scarce.

OBJECTIVES

This narrative review aims to update clinical microbiologists, infectious disease specialists and surgeons on the management of FRIs.

SOURCES

A computerized search of PubMed was performed to identify relevant studies. Search terms included 'Fracture' and 'Infection'. The reference lists of all retrieved articles were checked for additional relevant references. In addition, when scientific evidence was lacking, recommendations are based on expert opinion.

CONTENT

Pathogenesis, prevention, diagnosis and treatment of FRIs are presented. Whenever available, specific data of patients with FRI are discussed.

IMPLICATIONS

Management of patients with FRI should take into account FRI-specific features. Treatment pathways should implement a multidisciplinary approach to achieve a good outcome. Recently, international consensus guidelines were developed to improve the quality of care for patients suffering from this severe complication, which are highlighted in this review.

The Use of Radiation Therapy for the Treatment of Malignant Pleural Mesothelioma: Expert Opinion from the National Cancer Institute Thoracic Malignancy Steering Committee, International Association for the Study of Lung Cancer, and Mesothelioma Applied Research Foundation

INTRODUCTION

Detailed guidelines regarding the use of radiation therapy for malignant pleural mesothelioma (MPM) are currently lacking because of the rarity of the disease, the wide spectrum of clinical presentations, and the paucity of high-level data on individual treatment approaches.

METHODS

In March 2017, a multidisciplinary meeting of mesothelioma experts was cosponsored by the U.S. National Cancer Institute, International Association for the Study of Lung Cancer Research, and Mesothelioma Applied Research Foundation. Among the outcomes of this conference was the foundation of detailed, multidisciplinary consensus guidelines.

RESULTS

Here we present consensus recommendations on the use of radiation therapy for MPM in three discrete scenarios: (1) hemithoracic radiation therapy to be used before or after extrapleural pneumonectomy; (2) hemithoracic radiation to be used as an adjuvant to lung-sparing procedures (i.e., without pneumonectomy); and (3) palliative radiation therapy for focal symptoms caused by the disease. We discuss appropriate simulation techniques, treatment volumes, dose fractionation regimens, and normal tissue constraints. We also assess the role of particle beam therapy, specifically, proton beam therapy, for MPM.

CONCLUSION

The recommendations provided in this consensus statement should serve as important guidelines for developing future clinical trials of treatment approaches for MPM.

The generation of consensus guidelines for carrying out process evaluations in rehabilitation research

BACKGROUND

Although in recent years there has been a strong increase in published research on theories (e.g. realist evaluation, normalization process theory) driving and guiding process evaluations of complex interventions, there is limited guidance to help rehabilitation researchers design and carry out process evaluations. This can lead to the risk of process evaluations being unsystematic. This paper reports on the development of new consensus guidelines that address the specific challenges of conducting process evaluations alongside clinical trials of rehabilitation interventions.

METHODS

A formal consensus process was carried out based on a modified nominal group technique, which comprised two phases. Phase I was informed by the findings of a systematic review, and included a nominal group meeting with an expert panel of participants to rate and discuss the proposed statements. Phase II was an in depth semi-structured telephone interviews with expert panel participants in order to further discuss the structure and contents of the revised guidelines. Frequency of rating responses to each statement was calculated and thematic analysis was carried out on all qualitative data.

RESULTS

The guidelines for carrying out process evaluations within complex intervention rehabilitation research were produced by combining findings from Phase I and Phase II. The consensus guidelines include recommendations that are grouped in seven sections. These sections are theoretical work, design and methods, context, recruitment and retention, intervention staff, delivery of the intervention and results. These sections represent different aspects or stages of the evaluation process.

CONCLUSION

The consensus guidelines here presented can play a role at assisting rehabilitation researchers at the time of designing and conducting process evaluations alongside trials of complex interventions. The guidelines break new ground in terms of concepts and theory and works towards a consensus in regards to how rehabilitation researchers should go about carrying out process evaluations and how this evaluation should be linked into the proposed trials. These guidelines may be used, adapted and tested by rehabilitation researchers depending on the research stage or study design (e.g. feasibility trial, pilot trial, etc.).

Consensus recommendations for patient-centered therapy in mild-to-moderate ulcerative colitis: the i Support Therapy-Access to Rapid Treatment (iSTART) approach

Symptomatic ulcerative colitis (UC) can be a chronic, disabling condition. Flares in disease activity are associated with many of the negative impacts of mild-to-moderate UC. Rapid resolution of flares can provide benefits to patients and healthcare systems. i Support Therapy–Access to Rapid Treatment (iSTART) introduces patient-centered care for mild-to-moderate UC. iSTART provides patients with the ability to self-assess symptomology and self-start a short course of second-line treatment when necessary. An international panel of experts produced consensus statements and recommendations. These were informed by evidence from systematic reviews on the epidemiology, mesalazine (5-ASA) treatment, and patient use criteria for second-line therapy in UC. Optimized 5-ASA is the first-line treatment in all clinical guidelines, but may not be sufficient to induce remission in all patients. Corticosteroids should be prescribed as second-line therapy when needed, with budesonide MMX^® being a preferred steroid option. Active involvement of suitable patients in management of UC flares has the potential to improve therapy, with patients able to show good accuracy for flare self-assessment using validated tools. There is a place in the UC treatment pathway for an approach such as iSTART, which has the potential to provide patient, clinical and economic benefits.

Consensus nomenclature rules for radiopharmaceutical chemistry - Setting the record straight

Over recent years, within the community of radiopharmaceutical sciences, there has been an increased incidence of incorrect usage of established scientific terms and conventions, and even the emergence of 'self-invented' terms. In order to address these concerns, an international Working Group on 'Nomenclature in Radiopharmaceutical Chemistry and related areas' was established in 2015 to achieve clarification of terms and to generate consensus on the utilisation of a standardised nomenclature pertinent to the field. Upon open consultation, the following consensus guidelines were agreed, which aim to.

The impact of adjustments to the diagnostic criteria for biochemical remission in surgically treated patients with acromegaly

BACKGROUND

The suggested criteria for biochemical remission in patients treated for acromegaly were recently modified. The aim of this project was to study to what extent this modification influences remission rates.

DESIGN, PATIENTS AND METHODS

This was a retrospective study of 55 consecutive patients [29 men; median age 47years (interquartile range 38-68)] diagnosed with acromegaly between 2003 and 2014. After treatment serum IGF-I and/or GH was measured according to a standardized protocol. The biochemical remission status was defined according to the clinical guidelines from 2010 and2014.

RESULTS

Out of 55 patients, 44 patients were primarily operated. Of these, 33 (75%) were evaluated 3-12months postoperatively by measuring serum IGF-I and GH during an oral glucose tolerance test. According to the 2010 guidelines, 11 patients (33%) were in biochemical remission, 15 patients (46%) were not and 7 patients (21%) had discordant results (normal IGF-I and high GH or vice versa). Applying the 2014 guidelines in the same group, 16 patients (49%) were in biochemical remission, 7 patients (21%) were not and 10 patients (30%) had discordant results. Thus, by using the most recent criteria for biochemical control, more patients were considered to be in remission, or with discordant results, and fewer patients not in remission (P<0.05).

CONCLUSION

An apparently minor adjustment of the criteria for biochemical control has a significant impact on remission status in patients treated for acromegaly, eventually affecting follow-up and treatment strategies.

Current margin practice and effect on re-excision rates following the publication of the SSO-ASTRO consensus and ABS consensus guidelines: a national prospective study of 2858 women undergoing breast-conserving therapy in the UK and Ireland

INTRODUCTION

There is variation in margin policy for breast conserving therapy (BCT) in the UK and Ireland. In response to the Society of Surgical Oncology and American Society for Radiation Oncology (SSO-ASTRO) margin consensus ('no ink on tumour' for invasive and 2 mm for ductal carcinoma in situ [DCIS]) and the Association of Breast Surgery (ABS) consensus (1 mm for invasive and DCIS), we report on current margin practice and unit infrastructure in the UK and Ireland and describe how these factors impact on re-excision rates.

METHODS

A trainee collaborative-led multicentre prospective study was conducted in the UK and Ireland between 1st February and 31st May 2016. Data were collected on consecutive BCT patients and on local infrastructure and policies.

RESULTS

A total of 79 sites participated in the data collection (75% screening units; average 372 cancers annually, range 70-900). For DCIS, 53.2% of units accept 1 mm and 38% accept 2-mm margins. For invasive disease 77.2% accept 1 mm and 13.9% accept 'no ink on tumour'. A total of 2858 patients underwent BCT with a mean re-excision rate of 17.2% across units (range 0-41%). The re-excision rate would be reduced to 15% if all units applied SSO-ASTRO guidelines and to 14.8% if all units followed ABS guidelines. Of those who required re-operation, 65% had disease present at margin.

CONCLUSION

There continues to be large variation in margin policy and re-excision rates across units. Altering margin policies to follow either SSO-ASTRO or ABS guidelines would result in a modest reduction in the national re-excision rate. Most re-excisions are for involved margins rather than close margins.

Implementation of Models of Care for secondary osteoporotic fracture prevention and orthogeriatric Models of Care for osteoporotic hip fracture

As the world's population ages, the prevalence of osteoporosis and its resultant fragility fractures is set to increase dramatically. This chapter focuses on current frameworks and major initiatives related to the implementation of fracture liaison services (FLS) and orthogeriatrics services (OGS), Models of Care designed to reliably implement secondary fracture prevention measures for individuals presenting to health services with fragility fractures. The current evidence base regarding the impact and effectiveness of FLS and OGS is also considered.

Consensus guidelines for diagnosis, treatment and follow-up of patients with pancreatic cancer in Spain

The management of patients with pancreatic cancer has advanced over the last few years. We convey a multidisciplinary group of experts in an attempt to stablish practical guidelines for the diagnoses, staging and management of these patients. This paper summarizes the main conclusions of the working group. Patients with suspected pancreatic ductal adenocarcinoma should be rapidly evaluated and referred to high-volume centers. Multidisciplinary supervision is critical for proper diagnoses, staging and to frame a treatment plan. Surgical resection together with chemotherapy offers the highest chance for cure in early stage disease. Patients with advanced disease should be classified in treatment groups to guide systemic treatment. New chemotherapeutic regimens have resulted in improved survival. Symptomatic management is critical in this disease. Enrollment in a clinical trial is, in general, recommended.

Consensus guidelines for lumbar puncture in patients with neurological diseases

Introduction

Cerebrospinal fluid collection by lumbar puncture (LP) is performed in the diagnostic workup of several neurological brain diseases. Reluctance to perform the procedure is among others due to a lack of standards and guidelines to minimize the risk of complications, such as post-LP headache or back pain.

Methods

We provide consensus guidelines for the LP procedure to minimize the risk of complications. The recommendations are based on (1) data from a large multicenter LP feasibility study (evidence level II-2), (2) systematic literature review on LP needle characteristics and post-LP complications (evidence level II-2), (3) discussion of best practice within the Joint Programme Neurodegenerative Disease Research Biomarkers for Alzheimer's disease and Parkinson's Disease and Biomarkers for Multiple Sclerosis consortia (evidence level III).

Results

Our consensus guidelines address contraindications, as well as patient-related and procedure-related risk factors that can influence the development of post-LP complications.

Discussion

When an LP is performed correctly, the procedure is well tolerated and accepted with a low complication rate.

American Brachytherapy Society: Brachytherapy treatment recommendations for locally advanced cervix cancer for low-income and middle-income countries

PURPOSE

Most cervix cancer cases occur in low-income and middle-income countries (LMIC), and outcomes are suboptimal, even for early stage disease. Brachytherapy plays a central role in the treatment paradigm, improving both local control and overall survival. The American Brachytherapy Society (ABS) aims to provide guidelines for brachytherapy delivery in resource-limited settings.

METHODS AND MATERIALS

A panel of clinicians and physicists with expertise in brachytherapy administration in LMIC was convened. A survey was developed to identify practice patterns at the authors' institutions and was also extended to participants of the Cervix Cancer Research Network. The scientific literature was reviewed to identify consensus papers or review articles with a focus on treatment of locally advanced, unresected cervical cancer in LMIC.

RESULTS

Of the 40 participants invited to respond to the survey, 32 responded (response rate 80%). Participants were practicing in 14 different countries including both high-income (China, Singapore, Taiwan, United Kingdom, and United States) and low-income or middle-income countries (Bangladesh, Botswana, Brazil, India, Malaysia, Pakistan, Philippines, Thailand, and Vietnam). Recommendations for modifications to existing ABS guidelines were reviewed by the panel members and are highlighted in this article.

CONCLUSIONS

Recommendations for treatment of locally advanced, unresectable cervical cancer in LMIC are presented. The guidelines comment on staging, external beam radiotherapy, use of concurrent chemotherapy, overall treatment duration, use of anesthesia, applicator choice and placement verification, brachytherapy treatment planning including dose and prescription point, recommended reporting and documentation, physics support, and follow-up.

International consensus guidelines on Clinical Target Volume delineation in rectal cancer

INTRODUCTION

The delineation of Clinical Target Volume (CTV) is a critical step in radiotherapy. Several guidelines suggest different subvolumes and anatomical boundaries in rectal cancer (RC), potentially leading to a misunderstanding in the CTV definition. International consensus guidelines (CG) are needed to improve uniformity in RC CTV delineation.

MATERIAL AND METHODS

The 7 radiation oncologist experts defined a roadmap to produce RC CG. Step 1: revision of the published guidelines. Step 2: selection of RC cases with different clinical stages. Step 3: delineation of cases using Falcon following previously published guidelines. Step 4: meeting in person to discuss the initial delineation outcome, followed by a CTV proposal based on revised and if needed, adapted anatomical boundaries. Step 5: peer review of the agreed consensus. Step 6: peer review meeting to validate the final outcome. Step 7: completion of RC delineation atlases.

RESULTS

A new ontology of structure sets was defined and the related table of anatomical boundaries was generated. The major modifications were about the lateral lymph nodes and the ischio-rectal fossa delineation. Seven RC cases were made available online as consultation atlases.

CONCLUSION

The definition of international CG for RC delineation endorsed by international experts might support a future homogeneous comparison between clinical trial outcomes.

Preoperative platelet-to-lymphocyte ratio improves the performance of the international consensus guidelines in predicting malignant pancreatic cystic neoplasms

INTRODUCTION

To determine if neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were predictive of malignancy in pancreatic cystic neoplasms (PCN) and if these improved the performance of the international consensus guidelines (ICG) in the initial triage of these patients.

METHODS

318 patients with surgically-treated suspected PCN were retrospectively reviewed. Malignant neoplasms were defined as neoplasms harbouring invasive carcinoma. The optimal cut-off for NLR and PLR were determined by plotting the receiver operating characteristics (ROC) curves of NLR/PLR in predicting malignant PCN and utilizing the Youden index.

RESULTS

The optimal NLR and PLR cut-offs were determined to be 3.33 and 205, respectively. Univariate analyses demonstrated that symptomatic PCNs, age, obstructive jaundice, presence of solid component, dilatation of main pancreatic duct ≥10 mm, high NLR and high PLR were predictive of a malignant PCN. Multivariate analyses demonstrated that obstructive jaundice, presence of solid component, MPD ≥10 mm and high PLR but not NLR were independent predictors of a malignant PCN. A high PLR significantly predicted invasive carcinoma in patients classified within the ICG(HR) group. Comparison between the ROC curves of the ICG versus ICG plus high PLR in predicting malignant PCN demonstrated a significant improvement in the accuracy of the ICG when PLR was included [AUC 0.784 (95% CI: 0.740-0.829) vs AUC 0.822 (95% CI: 0.772-0.872) (p = 0.0032)].

CONCLUSIONS

High PLR is an independent predictor of malignancy in PCN. The addition of PLR as a criterion to the ICG improved the accuracy of these guidelines in detecting invasive neoplasms.

Management of non-muscle invasive bladder cancer: A comprehensive analysis of guidelines from the United States, Europe and Asia

Bladder cancer is the 8th most common cancer with 74,000 new cases in the United States in 2015. Non-muscle invasive bladder cancer (NMIBC) accounts for 75% of all bladder cancer cases. Transurethral resection and intravesical treatments remain the main treatment modality. Up to 31-78% of cases recur, hence the need for intensive treatment and surveillance protocols which makes bladder cancer one of the most expensive cancers to manage. The purpose of this review is to compare contemporary guidelines from Europe, (European Association of Urology), the United States (National Comprehensive Cancer Network), the United Kingdom (National Institute for Health and Care Excellence), Japan (Japanese Urological Association) and the International Consultation on Bladder Cancer (ICUD). We compare and contrast the different guidelines and the evidence on which their recommendations are based.

Fate of meta-analyses: The case of Helicobacter pylori

AIM: To overview the current diversity of meta-analysis and the implementation of their results in international guidelines.

METHODS: Relevant meta-analysis were identified from PubMed/Medline. The topics of meta-analyses were determined. Some topics (genetics, extragastric tumors) were analysed separately. Core journals publishing meta-analyses on Helicobacter pylori were ranked. The rate of citation of meta-analysis in major guidelines was calculated.

RESULTS: Between 1992 and 2014, some 356 meta-analyses were published on PubMed. These mainly appeared in core journals, but were also found in 128 other journals. Eradicating of the infection was the most addressed topic with 134 articles. Meta-analyses were rarely used in formulating statements and recommendations in the international guidelines. In other topics - genetics, extraintestinal manifestations - meta-analyses were rather overused.

CONCLUSION: The implementation of meta-analysis in current guidelines is rather rare, while other topics benefit from many studies. A more extensive use of meta-analyses in evidence-based medicine is recommended in the future, otherwise their continuous proliferation will lose reason and scientific significance.

Management of abdominal compartment syndrome and the open abdomen

OBJECTIVES

The management of the abdominal compartment syndrome (ACS) and the open abdomen (OA) are important to improve survival after major vascular surgery, in particular ruptured abdominal aortic aneurysm (RAAA). The aim is to summarize contemporary knowledge in this field.

METHODS

The consensus definitions of the World Society of the Abdominal Compartment Syndrome (WSACS) that were published in 2006 and the clinical practice guidelines published in 2007 were updated in 2013. Structured clinical questions were formulated (modified Delphi method), and the evidence base to answer those questions was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) guidelines.

RESULTS

Most of the previous definitions were kept untouched, or were slightly modified. Four new definitions were added, including a definition of OA and of lateralization of the abdominal wall, an important clinical problem to approach during prolonged OA treatment. A classification system of the OA was added. Seven recommendations were formulated, in summary: Trans-bladder intra-abdominal pressure (IAP) should be monitored in patients at risk. Protocolized monitoring and management are recommended, and decompression laparotomy if ACS. When OA, protocolized efforts to obtain an early abdominal fascial closure, and strategies utilizing negative pressure wound therapy should be used, versus not. In most cases the evidence was graded as weak or very weak. In six of the structured clinical questions, no recommendation could be made.

CONCLUSION

This review summarizes changes in definitions and management guidelines of relevance to vascular surgery, and data on the incidence of ACS after open and endovascular aortic surgery.

Differences in the management of pediatric and adult onset ulcerative colitis--lessons from the joint ECCO and ESPGHAN consensus guidelines for the management of pediatric ulcerative colitis

An expert panel of the European Crohn's and Colitis Organisation (ECCO) and European Society of Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) initiated a consensus process to produce the first pediatric specific ulcerative colitis (UC) guidelines based on a systematic literature review. Treatment strategies must reflect that pediatric-onset UC has a slightly different phenotype than adult-onset disease with more often extensive (pancolitis) and more aggressive disease course. Other pediatric-specific aspects include growth, puberty, bone density accrual and emotional development and body image acquisition. These differences and others influenced the development of pediatric treatment algorithms. It is recommended that virtually all children with UC must be treated with some maintenance therapy and 5-ASA requirement and dosing are often higher in children. A larger number of children are at risk for steroid-dependency, and this should not be tolerated; steroid sparing strategies with early use of immunosuppressors are recommended in high-risk patients. On the other hand, the safety profile of immunosuppressive therapy in children includes the rare forms of lymphomas and many future treatment years. Colectomy and pouch formation should be balanced in the treatment algorithms against the higher rate of future infertility in girls. The acute and on-going management of pediatric UC should be guided by evidence- and consensus-based balanced decisions, reflecting a vision of long-term treatment goals.

No consensus on definition criteria for stroke registry common data elements

BACKGROUND

Stroke registries contribute to the conduct of clinical research and to the assessment of health care quality control. Efforts to compare clinical outcomes and quality indicators between centers are dependent on standardized data elements, but it is unknown how stroke physicians define common data elements, such as hypertension or diabetes, when collecting data for registries at their centers.

METHODS

We conducted an internet-based survey of 91 centers affiliated with a university to assess their definitions of common data elements (CDEs) and compared their responses with standardized definitions, including those from the American College of Cardiology (ACC).

RESULTS

More than half (52%) of centers completed the survey. There was only modest agreement among respondents regarding definitions of CDEs in the survey and even less agreement on how the respondents' definitions compared to ACC standards.

CONCLUSIONS

Surveyed respondents do not agree on the definitions of CDEs, making comparisons between centers problematic. Standardized definitions of CDEs are needed to improve data collection for patient care and clinical research.
