Twenty-first Century Trends in the Global Epidemiology of Pediatric-Onset Inflammatory Bowel Disease: Systematic Review.

BACKGROUND & AIMS: The incidence of inflammatory bowel disease (IBD) is increasing internationally, particularly in nations with historically low rates. Previous reports of the epidemiology of pediatric-onset IBD identified a paucity of data. We systematically reviewed the global trends in incidence and prevalence of IBD diagnosed in individuals <21 years old over the first 2 decades of the 21st century. METHODS: We systematically reviewed studies indexed in MEDLINE, EMBASE, Airiti Library, and SciELO from January 2010 to February 2020 to identify population-based studies reporting the incidence and/or prevalence of IBD, Crohn's disease, ulcerative colitis, and/or IBD-unclassified. Data from studies published before 2000 were derived from a previously published systematic review. We described the geographic distribution and trends in children of all ages and limiting to very early onset (VEO) IBD. RESULTS: A total of 131 studies from 48 countries were included. The incidence and prevalence of pediatric-onset IBD is highest in Northern Europe and North America and lowest in Southern Europe, Asia, and the Middle East. Among studies evaluating trends over time, most (31 of 37, 84%) studies reported significant increases in incidence and all (7 of 7) reported significant increases in prevalence. Data on the incidence and prevalence of VEO-IBD are limited to countries with historically high rates of IBD. Time trends in the incidence of VEO-IBD were visually heterogeneous. CONCLUSIONS: Rates of pediatric-onset IBD continue to rise around the world and data are emerging from regions where it was not previously reported; however, there remains a paucity of data on VEO-IBD and on pediatric IBD from developing and recently developed countries.

Defining Pediatric Chronic Critical Illness: A Scoping Review.

OBJECTIVES: Children with chronic critical illness (CCI) are hypothesized to be a high-risk patient population with persistent multiple organ dysfunction and functional morbidities resulting in recurrent or prolonged critical care; however, it is unclear how CCI should be defined. The aim of this scoping review was to evaluate the existing literature for case definitions of pediatric CCI and case definitions of prolonged PICU admission and to explore the methodologies used to derive these definitions. DATA SOURCES: Four electronic databases (Ovid Medline, Embase, CINAHL, and Web of Science) from inception to March 3, 2021. STUDY SELECTION: We included studies that provided a specific case definition for CCI or prolonged PICU admission. Crowdsourcing was used to screen citations independently and in duplicate. A machine-learning algorithm was developed and validated using 6,284 citations assessed in duplicate by trained crowd reviewers. A hybrid of crowdsourcing and machine-learning methods was used to complete the remaining citation screening. DATA EXTRACTION: We extracted details of case definitions, study demographics, participant characteristics, and outcomes assessed. DATA SYNTHESIS: Sixty-seven studies were included. Twelve studies (18%) provided a definition for CCI that included concepts of PICU length of stay (n = 12), medical complexity or chronic conditions (n = 9), recurrent admissions (n = 9), technology dependence (n = 5), and uncertain prognosis (n = 1). Definitions were commonly referenced from another source (n = 6) or opinion-based (n = 5). The remaining 55 studies (82%) provided a definition for prolonged PICU admission, most frequently greater than or equal to 14 (n = 11) or greater than or equal to 28 days (n = 10). Most of these definitions were derived by investigator opinion (n = 24) or statistical method (n = 18). CONCLUSIONS: Pediatric CCI has been variably defined with regard to the concepts of patient complexity and chronicity of critical illness. A consensus definition is needed to advance this emerging and important area of pediatric critical care research.

Autoresuscitation after circulatory arrest: an updated systematic review.

PURPOSE: Current practice in organ donation after death determination by circulatory criteria (DCD) advises a five-minute observation period following circulatory arrest, monitoring for unassisted resumption of spontaneous circulation (i.e., autoresuscitation). In light of newer data, the objective of this updated systematic review was to determine whether a five-minute observation time was still adequate for death determination by circulatory criteria. SOURCE: We searched four electronic databases from inception to 28 August 2021, for studies evaluating or describing autoresuscitation events after circulatory arrest. Citation screening and data abstraction were conducted independently and in duplicate. We assessed certainty in evidence using the GRADE framework. PRINCIPAL FINDINGS: Eighteen new studies on autoresuscitation were identified, consisting of 14 case reports and four observational studies. Most studies evaluated adults (n = 15, 83%) and patients with unsuccessful resuscitation following cardiac arrest (n = 11, 61%). Overall, autoresuscitation was reported to occur between one and 20 min after circulatory arrest. Among all eligible studies identified by our reviews (n = 73), seven observational studies were identified. In observational studies of controlled withdrawal of life-sustaining measures with or without DCD (n = 6), 19 autoresuscitation events were reported in 1,049 patients (incidence 1.8%; 95% confidence interval, 1.1 to 2.8). All resumptions occurred within five minutes of circulatory arrest and all patients with autoresuscitation died. CONCLUSION: A five-minute observation time is sufficient for controlled DCD (moderate certainty). An observation time greater than five minutes may be needed for uncontrolled DCD (low certainty). The findings of this systematic review will be incorporated into a Canadian guideline on death determination. STUDY REGISTRATION: PROSPERO (CRD42021257827); registered 9 July 2021.

RéSUMé: OBJECTIF: La pratique actuelle en matière de don d'organes après une détermination du décès par critères circulatoires (DCC) préconise une période d'observation de cinq minutes après l'arrêt circulatoire et le monitorage de la reprise non assistée de la circulation spontanée (c.-à-d. l'auto-réanimation). À la lumière de données plus récentes, l'objectif de cette revue systématique mise à jour était de déterminer si un temps d'observation de cinq minutes était toujours suffisant pour une détermination de décès selon des critères circulatoires (DCC). SOURCES: Nous avons effectué des recherches dans quatre bases de données électroniques depuis leur création jusqu'au 28 août 2021 pour en tirer les études évaluant ou décrivant des événements d'autoréanimation après un arrêt circulatoire. L'examen des citations et l'extraction des données ont été réalisés de manière indépendante et en double. Nous avons évalué la certitude des données probantes à l'aide de la méthodologie GRADE. CONSTATATIONS PRINCIPALES: Dix-huit nouvelles études sur l'autoréanimation ont été identifiées, comprenant 14 présentations de cas et quatre études observationnelles. La plupart des études ont évalué des adultes (n = 15, 83 %) et les patients dont la réanimation avait échoué à la suite d'un arrêt cardiaque (n = 11, 61 %). Dans l'ensemble, l'autoréanimation a été signalée entre une et 20 minutes après l'arrêt circulatoire. Parmi toutes les études admissibles identifiées par nos comptes rendus (n = 73), sept études observationnelles ont été identifiées. Dans les études observationnelles sur l'interruption contrôlée des thérapies de maintien des fonctions vitales avec ou sans DCC (n = 6), 19 événements d'autoréanimation ont été rapportés chez 1049 patients (incidence 1,8 % ; intervalle de confiance à 95 %, 1,1 à 2,8). Toutes les reprises ont eu lieu dans les cinq minutes suivant l'arrêt circulatoire et tous les patients en autoréanimation sont décédés. CONCLUSION: Un temps d'observation de cinq minutes est suffisant pour un DCC contrôlé (certitude modérée). Un temps d'observation supérieur à cinq minutes peut être nécessaire en cas de DDC non contrôlé (faible certitude). Les résultats de cette revue systématique seront intégrés à des lignes directrices canadienne de pratique clinique sur la détermination du décès. ENREGISTREMENT DE L'éTUDE: PROSPERO (CRD42021257827); enregistrée le 9 juillet 2021.

A systematic review of evidence-based practices for clinical education and health care delivery in the clinical teaching unit.

BACKGROUND: The clinical teaching unit is a widespread clinical training model that requires reform to prepare physicians for practice in the 21st century. In this systematic review, we aimed to identify evidence-based practices in internal medicine clinical teaching units that contribute to improved clinical education and health care delivery. METHODS: We searched several databases from 1993 until Apr. 5, 2021, to identify published studies in inpatient clinical teaching units that involved medical trainees and reported outcomes related to trainee education or health care delivery. We identified emergent themes using a narrative approach and determined confidence in review findings using the Grading of Recommendations Assessment, Development and Evaluation Confidence in the Evidence from Reviews of Qualitative Research (GRADE-CERQual) methodology. RESULTS: We included 107 studies of internal medicine clinical teaching units, of which 93 (87%) were conducted in North America. Surveys (n = 31, 29%), trials (n = 17, 16%) and narrative studies (n = 15, 14%) were the most prevalent study designs. Practices identified as contributing to improved clinical education or health care delivery included purposeful rounding (high confidence), bedside rounding (moderate confidence), resource stewardship interventions (high confidence), interprofessional rounds (moderate confidence), geographic wards (moderate confidence), allocating more trainee time to patient care or educational activities (moderate confidence), "drip" continuous models of admission (moderate confidence), limiting duty hours (moderate confidence) and limiting clinical workload (moderate confidence). INTERPRETATION: In this review, we identified several evidence-based practices that may contribute to improved educational and health care outcomes in clinical teaching unit settings. These findings may offer guidance for policies, resource allocation and staffing of teaching hospitals.

Evaluating the relationship between citation set size, team size and screening methods used in systematic reviews: a cross-sectional study.

BACKGROUND: Standard practice for conducting systematic reviews (SRs) is time consuming and involves the study team screening hundreds or thousands of citations. As the volume of medical literature grows, the citation set sizes and corresponding screening efforts increase. While larger team size and alternate screening methods have the potential to reduce workload and decrease SR completion times, it is unknown whether investigators adapt team size or methods in response to citation set sizes. Using a cross-sectional design, we sought to understand how citation set size impacts (1) the total number of authors or individuals contributing to screening and (2) screening methods. METHODS: MEDLINE was searched in April 2019 for SRs on any health topic. A total of 1880 unique publications were identified and sorted into five citation set size categories (after deduplication): < 1,000, 1,001-2,500, 2,501-5,000, 5,001-10,000, and > 10,000. A random sample of 259 SRs were selected (~ 50 per category) for data extraction and analysis. RESULTS: With the exception of the pairwise t test comparing the under 1000 and over 10,000 categories (median 5 vs. 6, p = 0.049) no statistically significant relationship was evident between author number and citation set size. While visual inspection was suggestive, statistical testing did not consistently identify a relationship between citation set size and number of screeners (title-abstract, full text) or data extractors. However, logistic regression identified investigators were significantly more likely to deviate from gold-standard screening methods (i.e. independent duplicate screening) with larger citation sets. For every doubling of citation size, the odds of using gold-standard screening decreased by 15 and 20% at title-abstract and full text review, respectively. Finally, few SRs reported using crowdsourcing (n = 2) or computer-assisted screening (n = 1). CONCLUSIONS: Large citation set sizes present a challenge to SR teams, especially when faced with time-sensitive health policy questions. Our study suggests that with increasing citation set size, authors are less likely to adhere to gold-standard screening methods. It is possible that adjunct screening methods, such as crowdsourcing (large team) and computer-assisted technologies, may provide a viable solution for authors to complete their SRs in a timely manner.

Crowdsourcing the Citation Screening Process for Systematic Reviews: Validation Study.

BACKGROUND: Systematic reviews (SRs) are often cited as the highest level of evidence available as they involve the identification and synthesis of published studies on a topic. Unfortunately, it is increasingly challenging for small teams to complete SR procedures in a reasonable time period, given the exponential rise in the volume of primary literature. Crowdsourcing has been postulated as a potential solution. OBJECTIVE: The feasibility objective of this study was to determine whether a crowd would be willing to perform and complete abstract and full text screening. The validation objective was to assess the quality of the crowd's work, including retention of eligible citations (sensitivity) and work performed for the investigative team, defined as the percentage of citations excluded by the crowd. METHODS: We performed a prospective study evaluating crowdsourcing essential components of an SR, including abstract screening, document retrieval, and full text assessment. Using CrowdScreenSR citation screening software, 2323 articles from 6 SRs were available to an online crowd. Citations excluded by less than or equal to 75% of the crowd were moved forward for full text assessment. For the validation component, performance of the crowd was compared with citation review through the accepted, gold standard, trained expert approach. RESULTS: Of 312 potential crowd members, 117 (37.5%) commenced abstract screening and 71 (22.8%) completed the minimum requirement of 50 citation assessments. The majority of participants were undergraduate or medical students (192/312, 61.5%). The crowd screened 16,988 abstracts (median: 8 per citation; interquartile range [IQR] 7-8), and all citations achieved the minimum of 4 assessments after a median of 42 days (IQR 26-67). Crowd members retrieved 83.5% (774/927) of the articles that progressed to the full text phase. A total of 7604 full text assessments were completed (median: 7 per citation; IQR 3-11). Citations from all but 1 review achieved the minimum of 4 assessments after a median of 36 days (IQR 24-70), with 1 review remaining incomplete after 3 months. When complete crowd member agreement at both levels was required for exclusion, sensitivity was 100% (95% CI 97.9-100) and work performed was calculated at 68.3% (95% CI 66.4-70.1). Using the predefined alternative 75% exclusion threshold, sensitivity remained 100% and work performed increased to 72.9% (95% CI 71.0-74.6; P<.001). Finally, when a simple majority threshold was considered, sensitivity decreased marginally to 98.9% (95% CI 96.0-99.7; P=.25) and work performed increased substantially to 80.4% (95% CI 78.7-82.0; P<.001). CONCLUSIONS: Crowdsourcing of citation screening for SRs is feasible and has reasonable sensitivity and specificity. By expediting the screening process, crowdsourcing could permit the investigative team to focus on more complex SR tasks. Future directions should focus on developing a user-friendly online platform that allows research teams to crowdsource their reviews.

Observational study on resource utilisation of patients with limited English proficiency (LEP) at a high-LEP serving community hospital emergency department.

Communication barriers often result in healthcare disparities. Language barriers in patients with limited English proficiency (LEP) frequently results in higher healthcare expenditures and potentially poorer patient-centred outcomes. Therefore, we decided to assess resource utilisation of patients with LEP at our high-LEP serving community hospital emergency department (ED) in Canada. Specifically, we examined whether LEP patients have a higher rate of CT utilisation and/or a higher rate of hospital admission from the ED.We enrolled 100 patients who presented to the ED in our study. Each patient's English proficiency was rated. We classified 31 patients as LEP patients and 69 patients as non-LEP patients. Within the LEP patients' group, 13 out of 31 patients (42%) received a CT scan, while in the non-LEP patients' group, 30 out of 69 patients (43%) received a CT scan. In addition, 28 out of 31 patients (90%) from the LEP patients' group were admitted to the hospital after the initial ED consultation, while in the non-LEP patients' group, 51 out of 69 patients (74%) were admitted.We did not find a difference in CT scan utilisation between LEP and non-LEP patients (p=0.89). Although there is a trend towards a higher hospital admission rate in LEP patients, our finding was not statistically significant (p=0.062).

Perioperative Factors Associated With Postoperative Delirium in Patients Undergoing Noncardiac Surgery: An Individual Patient Data Meta-Analysis.

Importance: Postoperative delirium (POD) is a common and serious complication after surgery. Various predisposing factors are associated with POD, but their magnitude and importance using an individual patient data (IPD) meta-analysis have not been assessed. Objective: To identify perioperative factors associated with POD and assess their relative prognostic value among adults undergoing noncardiac surgery. Data Sources: MEDLINE, EMBASE, and CINAHL from inception to May 2020. Study Selection: Studies were included that (1) enrolled adult patients undergoing noncardiac surgery, (2) assessed perioperative risk factors for POD, and (3) measured the incidence of delirium (measured using a validated approach). Data were analyzed in 2020. Data Extraction and Synthesis: Individual patient data were pooled from 21 studies and 1-stage meta-analysis was performed using multilevel mixed-effects logistic regression after a multivariable imputation via chained equations model to impute missing data. Main Outcomes and Measures: The end point of interest was POD diagnosed up to 10 days after a procedure. A wide range of perioperative risk factors was considered as potentially associated with POD. Results: A total of 192 studies met the eligibility criteria, and IPD were acquired from 21 studies that enrolled 8382 patients. Almost 1 in 5 patients developed POD (18%), and an increased risk of POD was associated with American Society of Anesthesiologists (ASA) status 4 (odds ratio [OR], 2.43; 95% CI, 1.42-4.14), older age (OR for 65-85 years, 2.67; 95% CI, 2.16-3.29; OR for >85 years, 6.24; 95% CI, 4.65-8.37), low body mass index (OR for body mass index <18.5, 2.25; 95% CI, 1.64-3.09), history of delirium (OR, 3.9; 95% CI, 2.69-5.66), preoperative cognitive impairment (OR, 3.99; 95% CI, 2.94-5.43), and preoperative C-reactive protein levels (OR for 5-10 mg/dL, 2.35; 95% CI, 1.59-3.50; OR for >10 mg/dL, 3.56; 95% CI, 2.46-5.17). Completing a college degree or higher was associated with a decreased likelihood of developing POD (OR 0.45; 95% CI, 0.28-0.72). Conclusions and Relevance: In this systematic review and meta-analysis of individual patient data, several important factors associated with POD were found that may help identify patients at high risk and may have utility in clinical practice to inform patients and caregivers about the expected risk of developing delirium after surgery. Future studies should explore strategies to reduce delirium after surgery.

Ergonomic Recommendations in Ultrasound-Guided Botulinum Neurotoxin Chemodenervation for Spasticity: An International Expert Group Opinion.

Ultrasound (US)-guided botulinum neurotoxin (BoNT) injections are becoming a mainstay in the treatment of muscle spasticity in upper motor neuron syndromes. As a result, there has been a commensurate increase in US-guided BoNT injection for spasticity training courses. However, many of these courses do not emphasize the importance of ergonomics. This paper aims to highlight the importance of ultrasound ergonomics and presents ergonomic recommendations to optimize US-guided BoNT injection techniques in spasticity management. Expert consensus opinion of 11 physicians (4 different continents; representing 8 countries, with an average of 12.6 years of practice using US guidance for BoNT chemodenervation (range 3 to 22 years)). A search using PubMed, College of Physicians and Surgeons of British Columbia database, EMbase was conducted and found no publications relating the importance of ergonomics in US-guided chemodenervation. Therefore, recommendations and consensus discussions were generated from the distribution of a 20-question survey to a panel of 11 ultrasound experts. All 11 surveyed physicians considered ergonomics to be important in reducing physician injury. There was complete agreement that physician positioning was important; 91% agreement that patient positioning was important; and 82% that ultrasound machine positioning was important. Factors that did not reach our 80% threshold for consensus were further discussed. Four categories were identified as being important when implementing ultrasound ergonomics for BoNT chemodenervation for spasticity; workstation, physician, patient and visual ergonomics. Optimizing ergonomics is paramount when performing US-guided BoNT chemodenervation for spasticity management. This includes proper preparation of the workspace and allowing for sufficient pre-injection time to optimally position both the patient and the physician. Lack of awareness of ergonomics for US-guided BoNT chemodenervation for spasticity may lead to suboptimal patient outcomes, increase work-related injuries, and patient discomfort. We propose key elements for optimal positioning of physicians and patients, as well as the optimal setup of the workspace and provide clinical pearls in visual identification of spastic muscles for chemodenervation.

A Guide to Extract Spinal Cord for Translational Stem Cell Biology Research: Comparative Analysis of Adult Human, Porcine, and Rodent Spinal Cord Stem Cells.

Improving the clinical translation of animal-based neural stem/progenitor cell (NSPC) therapies to humans requires an understanding of intrinsic human and animal cell characteristics. We report a novel in vitro method to assess spinal cord NSPCs from a small (rodent) and large (porcine) animal model in comparison to human NSPCs. To extract live adult human, porcine, and rodent spinal cord tissue, we illustrate a strategy using an anterior or posterior approach that was simulated in a porcine model. The initial expansion of primary NSPCs is carried out using the neurosphere assay followed by a pharmacological treatment phase during which NSPCs derived from humans, porcines, and rodents are assessed in parallel using the same defined parameters. Using this model, NSPCs from all species demonstrated multi-lineage differentiation and self-renewal. Importantly, these methods provide conditions to enable the direct comparison of species-dependent cell behavior in response to specific exogenous signals.

Effect of treating elbow flexor spasticity with botulinum toxin injection and adjunctive casting on hemiparetic gait parameters: A prospective case series.

OBJECTIVE: To investigate changes in hemiparetic gait parameters after treatment of elbow flexor spasticity with botulinum neurotoxin (BoNT) injection and adjunctive casting. DESIGN: Prospective case series. SUBJECTS: Ten participants with spasticity secondary to acquired brain injury (8 stroke, 2 traumatic brain injury). INTERVENTIONS: Participants received BoNT injections for their spastic elbow flexors under ultrasound guid-ance. Two weeks post-injection, an elbow stretching cast was applied for 1 week. OUTCOME MEASURES: Assessments using the Modified Ashworth Scale (MAS), Tardieu scale V1 angle of arrest at slow speed and V3 angle of catch at fast speed, 2-min walk test (2MWT), Edinburgh Gait Score scale (EGS) and video gait analysis for step-length symmetry were conducted pre-BoNT injection (t0) and at cast removal (t1). Goal attainment scale (GAS) was used to assess changes in spasticity and gait 3 months post-injection (t2). RESULTS: At t1, participants showed a mean increase of 16.7° (p < 0.01) on the Tardieu Scale V3 and a mean reduction of 0.5 points on the MAS (p < 0.05). There was also a mean reduction on EGS of 2.7 points (p < 0.05), and a mean increase on 2MWT of 3.1 m (p < 0.05). On the GAS, all participants report-ed impro-ved gait at t2 and 80% reported a decrease in spasticity. CONCLUSION: Combining BoNT injection with casting for treatment of elbow flexor spasticity without treat-ing the lower limb may improve hemiparetic gait parameters.

Clinical teaching unit design: a realist systematic review protocol of evidence-based practices for clinical education and health service delivery.

INTRODUCTION: The clinical teaching unit (CTU) has emerged as a near-ubiquitous model of clinical education across Canadian and international medical schools since it was first proposed over 50 years ago. However, while healthcare has changed dramatically over this period, the CTU model has remained largely unchanged. We thus aimed to systematically review principles of CTU design that contribute to improved outcomes in clinical education and health service delivery. METHODS AND ANALYSIS: We will perform a realist systematic review in accordance with the Realist And Meta-narrative Evidence Syntheses: Evolving Standards (RAMESES) II protocol for realist reviews. Databases, including MEDLINE, Embase, Cochrane Database of Systematic Reviews and Cumulative Index of Nursing and Allied Health Literature (CINAHL), were searched to find primary research articles published from 1993 to 2019 involving CTUs or other teaching wards, and outcomes related to either trainee education or health service delivery. Two reviewers will independently screen studies in a two-stage process. Retrieved titles and/or abstracts of studies will be screened in the first stage, with full texts reviewed in the second stage. Selected articles meeting inclusion criteria will undergo data abstraction using a standardised, pre-piloted form for assessment of study quality and knowledge synthesis. ETHICS AND DISSEMINATION: This review will generate higher quality evidence on the design of CTUs as a model for both clinical education and health service delivery. In addition, further knowledge translation efforts may be necessary to ensure that known best practices in CTU design become common practice.

Design and evaluation of a biosynthesized cellulose drug releasing duraplasty.

Decompressive craniectomy (DC) is a standard surgical procedure performed on stroke patients in which a portion of a skull is removed and a duraplasty membrane is applied onto the brain. While DC can significantly reduce the risk of death, it does not reverse the stroke damage. In this study, a novel biosynthesized cellulose (BC)-based drug releasing duraplasty was developed and studied. The BC duraplasty fabrication process allowed readily incorporation of growth factors (GFs) in a sterile manner and control of physical and mechanical properties of the resulting duraplasty. Our results showed that BC duraplasty containing the highest amount of dry cellulose presented swelling ratio of 496 ± 27%, Young's modulus of 0.37 ± 0.02 MPa, ultimate tensile strength of 0.96 ± 0.02 MPa, while releasing GFs for over 10 days. In addition, neural stem/progenitor cell (NSPC) cultures demonstrated that the GFs released from the BC duraplasty promoted NSPC proliferation and differentiation in vitro. Finally, animal studies revealed that the BC duraplasty did not cause any inflammatory reactions after the DC procedure in vivo. In summary, this newly developed GF loaded BC membrane demonstrates a promising potential as drug releasing duraplasty, not only for stroke treatments but also for traumatic brain injuries and spinal cord injuries.

Identification and Evaluation of Controlled Trials in Pediatric Cardiology: Crowdsourced Scoping Review and Creation of Accessible Searchable Database.

Cardiac disease in children is associated with significant morbidity and mortality as well as increased health resource utilisation. There is a perception that there is a paucity of high-quality studies, particularly randomized controlled trials (RCTs), in the field of pediatric cardiology. We sought to identify, examine, and map the range of RCTs conducted in children with cardiac conditions, including the development of a searchable open-access database. A literature search was conducted encompassing MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials from inception to 2018. All English-language RCTs enrolling children (age 0-21 years) with cardiac conditions were included. Data extraction and risk of bias assessments were performed in duplicate via crowdsourcing for each eligible study and entered into an online database. A total of 933 RCTs met eligibility criteria. Median trial recruitment was 49 patients (interquartile range 30-86) with 18.9% of studies (n = 176) including > 100 patients. A wide variety of populations and interventions were encompassed with congenital heart disease (79.8% of RCTs) and medications (63.3% of RCTs) often studied. Just over one-half of the trials (53.4%) clearly identified a primary outcome, and fewer than half (46.6%) fully documented a robust randomization process. Trials were summarised in a searchable online database (https://pediatrics.knack.com/cardiology-rct-database#cardiology-rcts/). Contrary to a commonly held perception, there are nearly 1,000 published RCTs in pediatric cardiology. The open-access database created as part of this project provides a resource that facilitates an efficient comprehensive review of the literature for clinicians and researchers caring for children with cardiac issues.
