RESUMEN

BACKGROUND: The COVID-19 pandemic has led to increased utilization of telemedicine services. METHODS: A retrospective analysis of all referral-based ambulatory telemedicine services in Ontario from November 2019 to June 2021 was collected from the Ontario Health Insurance Plan (OHIP) billing database. Only fee-for-service billings were included in the present analysis. Coincident COVID-19 cases were obtained from Public Health Ontario. Comparisons were made based on age bracket, sex, telemedicine and in-person care. RESULTS: Billings for telemedicine services in Ontario increased from $1.7 million CAD in November 2019 to $64 million CAD in April 2020 and the proportions reached a mean peak of 72% in April 2020 and declined to 46% in June 2021. A positive correlation was found between the use of telemedicine and COVID-19 cases (p = 0.05). The age group with the highest proportion of telemedicine use was the 10-20-year-olds, followed by the 20-50-year-olds (61 ± 9.0%, 55 ± 7.3%, p = 0.01). Both age groups remained above 50% telemedicine services at the end of the study period. There seemed to be higher utilization by females (females 54.2 ± 8.0%, males 47.9 ± 7.7%, ANCOVA p = 0.05) for all specialties, however, after adjusting for male to female ratio m:f of 0.952:1.0 according to the 2016 census, this was no longer significant. CONCLUSIONS: The use of telemedicine services remained at a high level across groups, particularly the 10-50-year-olds. There were clear age preferences for using telemedicine. Studying these differences may provide insights into how the delivery of non-hospital-based medicine has changed during the COVID-19 pandemic.

RESUMEN

BACKGROUND: Helping Babies Breathe (HBB) is a life-saving program that has helped reduce neonatal morbidity and mortality, but knowledge and skills retention after training remains a significant challenge for sustainability of impact. User-centred design (UCD) can be used to develop solutions to target knowledge and skills maintenance. METHODS: We applied a process of UCD beginning with understanding the facilitators of, and barriers to, learning and retaining HBB knowledge and skills. HBB Master Trainers and frontline HBB providers participated in a series of focus group discussions (FGDs) to uncover the processes of skills acquisition and maintenance to develop a mobile application called "HBB Prompt". Themes derived from each FGD were identified and implications for development of the HBB Prompt app were explored, including feasibility of incorporating strategies into the format of an app. Data analysis took place after each iteration in Phase 1 to incorporate feedback and improve subsequent versions of HBB Prompt. RESULTS: Six HBB trainers and seven frontline HBB providers participated in a series of FGDs in Phase 1 of this study. Common themes included lack of motivation to practise, improving confidence in ventilation skills, ability to achieve the Golden Minute, fear of forgetting knowledge or skills, importance of feedback, and peer-to-peer learning. Themes identified that were not feasible to address pertained to health system challenges. Feedback about HBB Prompt was generally positive. Based on initial and iterative feedback, HBB Prompt was created with four primary functions: Training Mode, Simulation Mode, Quizzes, and Dashboard/Scoreboard. CONCLUSIONS: Developing HBB Prompt with UCD to help improve knowledge and skills retention was feasible and revealed key concepts, including drivers for successes and challenges faced for learning and maintaining HBB skills. HBB Prompt will be piloted in Phase 2 of this study, where knowledge and skills retention after HBB training will be compared between an intervention group with HBB Prompt and a control group without the app. Trial registration Clinicaltrials.gov (NCT03577054). Retrospectively registered July 5, 2018, https://clinicaltrials.gov/ct2/show/study/NCT03577054 .

RESUMEN

BACKGROUND: White matter lesions are frequently detected using brain magnetic resonance imaging (MRI) performed for various indications. Most are microangiopathic, but demyelination, including multiple sclerosis (MS), is an important cause; conventional MRI cannot always distinguish between these pathologies. The proportion of lesions with a central vein on 7-T T2*-weighted MRI prospectively distinguishes demyelination from microangiopathic lesions. OBJECTIVE: To test whether 3-T T2*-weighted MRI can differentiate MS from microangiopathic brain lesions. METHODS: A total of 40 patients were studied. Initially, a test cohort of 10 patients with MS and 10 patients with microangiopathic white matter lesions underwent 3-T T2*-weighted brain MRI. Anonymised scans were analysed blind to clinical data, and simple diagnostic rules were devised. These rules were applied to a validation cohort of 20 patients (13 with MS and 7 with microangiopathic lesions) by a blinded observer. RESULTS: Within the test cohort, all patients with MS had central veins visible in >45% of brain lesions, while the rest had central veins visible in <45% of lesions. By applying diagnostic rules to the validation cohort, all remaining patients were correctly categorised. CONCLUSION: 3-T T2*-weighted brain MRI distinguishes perivenous MS lesions from microangiopathic lesions. Clinical application of this technique could supplement existing diagnostic algorithms.

RESUMEN

BACKGROUND: Degeneration of central nervous system normal appearing white matter (NAWM) underlies disability and progression in multiple sclerosis (MS). Axon loss typifies NAWM degeneration. OBJECTIVE: The objective of this paper is to assess correlation between cortical lesion load and magnetisation transfer ratio (MTR) of the NAWM in MS. This was in order to test the hypothesis that cortical lesions cause NAWM degeneration. METHODS: Nineteen patients with MS underwent 7 Tesla magnetisation-prepared-rapid-acquisition-gradient-echo (MPRAGE), and magnetisation transfer ratio (MTR) brain magnetic resonance imaging (MRI). Cortical lesions were identified using MPRAGE and MTR images of cortical ribbons. White matter lesions (WMLs) were segmented using MPRAGE images. WML maps were subtracted from white matter volumes to produce NAWM masks. Pearson correlation was calculated for NAWM MTR vs cortical lesion load, and WML volumes. RESULTS: Cortical lesion volumes and counts all had significant correlation with NAWM mean MTR. The strongest correlation was with cortical lesion volumes obtained using MTR images (r = -0.6874, p = 0.0006). WML volume had no significant correlation with NAWM mean MTR (r = -0.08706, p = 0.3615). CONCLUSION: Our findings are consistent with the hypothesis that cortical lesions cause NAWM degeneration. This implicates cortical lesions in the pathogenesis of NAWM axon loss, which underpins long-term disability and progression in MS.

RESUMEN

BACKGROUND: Microvascular dysfunction in HCM has been associated with adverse clinical outcomes. Advances in quantitative cardiovascular magnetic resonance (CMR) perfusion imaging now allow myocardial blood flow to be quantified at the pixel level. We applied these techniques to investigate the spectrum of microvascular dysfunction in hypertrophic cardiomyopathy (HCM) and to explore its relationship with fibrosis and wall thickness. METHODS: CMR perfusion imaging was undertaken during adenosine-induced hyperemia and again at rest in 35 patients together with late gadolinium enhancement (LGE) imaging. Myocardial blood flow (MBF) was quantified on a pixel-by-pixel basis from CMR perfusion images using a Fermi-constrained deconvolution algorithm. Regions-of-interest (ROI) in hypoperfused and hyperemic myocardium were identified from the MBF pixel maps. The myocardium was also divided into 16 AHA segments. RESULTS: Resting MBF was significantly higher in the endocardium than in the epicardium (mean ± SD: 1.25 ± 0.35 ml/g/min versus 1.20 ± 0.35 ml/g/min, P<0.001), a pattern that reversed with stress (2.00 ± 0.76 ml/g/min versus 2.36 ± 0.83 ml/g/min, P<0.001). ROI analysis revealed 11 (31%) patients with stress MBF lower than resting values (1.05 ± 0.39 ml/g/min versus 1.22 ± 0.36 ml/g/min, P=0.021). There was a significant negative association between hyperemic MBF and wall thickness (ß=-0.047 ml/g/min per mm, 95% CI: -0.057 to -0.038, P<0.001) and a significantly lower probability of fibrosis in a segment with increasing hyperemic MBF (odds ratio per ml/g/min: 0.086, 95% CI: 0.078 to 0.095, P=0.003). CONCLUSIONS: Pixel-wise quantitative CMR perfusion imaging identifies a subgroup of patients with HCM that have localised severe microvascular dysfunction which may give rise to myocardial ischemia.

RESUMEN

BACKGROUND: People who are prescribed self administered medications typically take only about half their prescribed doses. Efforts to assist patients with adherence to medications might improve the benefits of prescribed medications. OBJECTIVES: The primary objective of this review is to assess the effects of interventions intended to enhance patient adherence to prescribed medications for medical conditions, on both medication adherence and clinical outcomes. SEARCH METHODS: We updated searches of The Cochrane Library, including CENTRAL (via http://onlinelibrary.wiley.com/cochranelibrary/search/), MEDLINE, EMBASE, PsycINFO (all via Ovid), CINAHL (via EBSCO), and Sociological Abstracts (via ProQuest) on 11 January 2013 with no language restriction. We also reviewed bibliographies in articles on patient adherence, and contacted authors of relevant original and review articles. SELECTION CRITERIA: We included unconfounded RCTs of interventions to improve adherence with prescribed medications, measuring both medication adherence and clinical outcome, with at least 80% follow-up of each group studied and, for long-term treatments, at least six months follow-up for studies with positive findings at earlier time points. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted all data and a third author resolved disagreements. The studies differed widely according to medical condition, patient population, intervention, measures of adherence, and clinical outcomes. Pooling results according to one of these characteristics still leaves highly heterogeneous groups, and we could not justify meta-analysis. Instead, we conducted a qualitative analysis with a focus on the RCTs with the lowest risk of bias for study design and the primary clinical outcome. MAIN RESULTS: The present update included 109 new RCTs published since the previous update in January 2007, bringing the total number of RCTs to 182; we found five RCTs from the previous update to be ineligible and excluded them. Studies were heterogeneous for patients, medical problems, treatment regimens, adherence interventions, and adherence and clinical outcome measurements, and most had high risk of bias. The main changes in comparison with the previous update include that we now: 1) report a lack of convincing evidence also specifically among the studies with the lowest risk of bias; 2) do not try to classify studies according to intervention type any more, due to the large heterogeneity; 3) make our database available for collaboration on sub-analyses, in acknowledgement of the need to make collective advancement in this difficult field of research. Of all 182 RCTs, 17 had the lowest risk of bias for study design features and their primary clinical outcome, 11 from the present update and six from the previous update. The RCTs at lowest risk of bias generally involved complex interventions with multiple components, trying to overcome barriers to adherence by means of tailored ongoing support from allied health professionals such as pharmacists, who often delivered intense education, counseling (including motivational interviewing or cognitive behavioral therapy by professionals) or daily treatment support (or both), and sometimes additional support from family or peers. Only five of these RCTs reported improvements in both adherence and clinical outcomes, and no common intervention characteristics were apparent. Even the most effective interventions did not lead to large improvements in adherence or clinical outcomes. AUTHORS' CONCLUSIONS: Across the body of evidence, effects were inconsistent from study to study, and only a minority of lowest risk of bias RCTs improved both adherence and clinical outcomes. Current methods of improving medication adherence for chronic health problems are mostly complex and not very effective, so that the full benefits of treatment cannot be realized. The research in this field needs advances, including improved design of feasible long-term interventions, objective adherence measures, and sufficient study power to detect improvements in patient-important clinical outcomes. By making our comprehensive database available for sharing we hope to contribute to achieving these advances.

RESUMEN

The failure of relapses and white matter lesions to properly explain long-term disability and progression in multiple sclerosis is compounded by its artificial separation into relapsing remitting, secondary progressive, and primary progressive pigeonholes. The well-known epidemiological disconnection between relapses and long-term disability progression has been rediscovered as "progression independent of relapse activity", i.e. smouldering multiple sclerosis. This smouldering associated worsening proceeds despite early and prolonged use of disease modification therapies, even those that are highly effective at preventing relapses and new/enhancing white matter lesions on MRI. We recognise that smouldering associated worsening and relapse/lesion associated worsening coexist, to varying extents. The extent of cortical demyelination has been shown to correlate significantly with the severity of diffuse injury in normal appearing white matter (post mortem histopathologically (r = 0.55; P = 0.001), and in vivo with MRI (r = -0.6874; P = 0.0006)) and does so independently of white matter lesion burden. Axon loss in the normal appearing white matter explains disability in multiple sclerosis better than focal white matter lesions do. Smouldering associated worsening typically manifests as a length-dependent central axonopathy. We propose a unifying model for multiple sclerosis pathogenesis, wherein accumulation of cortical lesion burden predisposes associated normal appearing white matter to diffuse injury, whilst also intensifying damage within white matter lesions. Our novel two-hit hypothesis implicates cortical disease as a culprit for smouldering multiple sclerosis, abetted by active focal inflammation in the white matter (and vice versa). Substantiation of the two-hit hypothesis would advance the importance of specific therapeutic intervention for (and monitoring of) cortical/meningeal inflammation in people with multiple sclerosis.

RESUMEN

BACKGROUND: Over 10 million newborns worldwide undergo resuscitation at birth each year. Pediatricians may use electrocardiogram (ECG), pulse oximetry (PO), and stethoscope in determining heart rate (HR), as HR guides the need for and steps of resuscitation. HR must be obtained quickly and accurately. Unfortunately, the current diagnostic modalities are either too slow, obtaining HR in more than a minute, or inaccurate. With time constraints, a reliable robust heart rate detector (HRD) modality is required. This paper discusses a protocol for conducting a methods-based comparison study to determine the HR accuracy of a novel real-time HRD based on 3D-printed dry-electrode single-lead ECG signals for cost-effective and quick HR determination. The HRD's HR results are compared to either clinical-grade ECG or PO monitors to ensure robustness and accuracy. OBJECTIVE: The purpose of this study is to design and examine the feasibility of a proof-of-concept HRD that quickly obtains HR using biocompatible 3D-printed dry electrodes for single-lead neonatal ECG acquisition. This study uses a novel HRD and compares it to the gold-standard 3-lead clinical ECG or PO in a hospital setting. METHODS: A cross-sectional study is planned to be conducted in the neonatal intensive care unit or postpartum unit of a large community teaching hospital in Toronto, Canada, from June 2023 to June 2024. In total, 50 newborns will be recruited for this study. The HRD and an ECG or PO monitor will be video recorded using a digital camera concurrently for 3 minutes for each newborn. Hardware-based signal processing and patent-pending embedded algorithm-based HR estimation techniques are applied directly to the raw collected single-lead ECG and displayed on the HRD in real time during video recordings. These data will be annotated and compared to the ECG or PO readings at the same points in time. Accuracy, F1-score, and other statistical metrics will be produced to determine the HRD's feasibility in providing reliable HR. RESULTS: The study is ongoing. The projected end date for data collection is around July 2024. CONCLUSIONS: The study will compare the novel patent-pending 3D-printed dry electrode-based HRD's real-time HR estimation techniques with the state-of-the-art clinical-grade ECG or PO monitors for HR accuracy and examines how fast the HRD provides reliable HR. The study will further provide recommendations and important improvements that can be made to implement the HRD for clinical applications, especially in neonatal resuscitation efforts. This work can be seen as a stepping stone in the development of robust dry-electrode single-lead ECG devices for HR estimations in the pediatric population.

RESUMEN

INTRODUCTION: This meta-analysis aimed to determine the comparative effectiveness of timed alarm device-assisted urotherapy vs. standard urotherapy alone in managing pediatric daytime urinary incontinence (pDUI). METHODS: A systematic literature search was performed in December 2021, with an update search in July 2022. Comparative studies assessing the pDUI treatment effectiveness of timed alarm device-assisted urotherapy vs. urotherapy alone were identified and evaluated according to Cochrane collaboration recommendations. The assessed outcome includes pDUI complete response and adherence rates. Relative risk (RR ) with 95% confidence intervals (CI) was extrapolated. A random-effects model was used to pool effect estimates. Heterogeneity was assessed with sensitivity and subgroup analysis performed according to study design and comparative group characteristics. GRADE criteria were used to assess evidence certainty. (PROSPEROCRD 42022299173). RESULTS: Four studies (three randomized controlled trials [RCTs] and one retrospective cohort) with 635 cases were included. The pooled effect estimates of pDUI complete response showed no differences between intervention groups (RR 1.20, 95% CI 0.81, 1.76). Pooled effect estimates for treatment adherence were generated from two studies, which showed significantly better adherence for the timed-alarm device group (RR 2.97, 95% CI 1.46, 6.06). Significant interstudy heterogeneity was noted; the source is likely from the study design and comparator device characteristics. The quality of evidence was assessed to be of very low certainty. CONCLUSIONS: Based on very low certainty evidence, timed alarm device-assisted urotherapy does not seem to have the advantage of complete treatment response over standard urotherapy alone in managing pDUI; however, a timed-alarm device is likely able to improve urotherapy treatment adherence.

RESUMEN

BACKGROUND: Helping Babies Breathe (HBB) is a newborn resuscitation training program designed to reduce neonatal mortality in low- and middle-income countries. However, skills decay after initial training is a significant barrier to sustained impact. OBJECTIVE: To test whether a mobile app, HBB Prompt, developed with user-centred design, helps improve skills and knowledge retention after HBB training. METHODS: HBB Prompt was created during Phase 1 of this study with input from HBB facilitators and providers from Southwestern Uganda recruited from a national HBB provider registry. During Phase 2, healthcare workers (HCWs) in two community hospitals received HBB training. One hospital was randomly assigned as the intervention hospital, where trained HCWs had access to HBB Prompt, and the other served as control without HBB Prompt (NCT03577054). Participants were evaluated using the HBB 2.0 knowledge check and Objective Structured Clinical Exam, version B (OSCE B) immediately before and after training, and 6 months post-training. The primary outcome was difference in OSCE B scores immediately after training and 6 months post-training. RESULTS: Twenty-nine HCWs were trained in HBB (17 in intervention, 12 in control). At 6 months, 10 HCW were evaluated in intervention and 7 in control. In intervention and control respectively, the median OSCE B scores were: 7 vs. 9 immediately before training, 17 vs. 21 immediately after training, and 12 vs. 13 at 6 months after training. Six months after training, the median difference in OSCE B scores was -3 (IQR -5 to -1) in intervention and -8 (IQR -11 to -6) in control (p = 0.02). CONCLUSION: HBB Prompt, a mobile app created by user-centred design, improved retention of HBB skills at 6 months. However, skills decay remained high 6 months after training. Continued adaptation of HBB Prompt may further improve maintenance of HBB skills.

RESUMEN

BACKGROUND: When constipation is refractory to first-line interventions, antegrade enema use may be considered. We aimed to assess the impact of this intervention on healthcare utilization. METHODS: We conducted a population-based, quasi-experimental study with pre-post comparison of the intervention group and a non-equivalent control group using linked clinical and health administrative data from Ontario, Canada. Subjects included children (0-18 years) who underwent antegrade enema initiation from 2007 to 2020 and matched controls (4:1) from the general population. To assess the change in healthcare utilization following antegrade enema initiation, we used negative binomial generalized estimating equations with covariates selected a priori. KEY RESULTS: One hundred thirty-eight subjects met eligibility criteria (appendicostomy = 55 (39.9%); cecostomy tube = 83 (60.1%)) and were matched to 550 controls. There was no significant difference in the change in the rate of hospitalizations (rate ratio (RR) 1.05, 95% confidence interval (CI) 0.35-1.75), outpatient visits (RR 1.05, 95% CI 0.91-1.18), or same-day surgical procedures (RR 1.51, 95% CI 0.60-2.43) across cases in 2 years following antegrade enema initiation compared with controls. Cases had an increased rate of emergency department (ED) visits, which was not observed in controls (RR 1.52, 95% CI 1.11-1.79), driven in part by device-related complications. CONCLUSIONS AND INFERENCES: Understanding healthcare utilization patterns following antegrade enema initiation allows for effective health system planning and aids medical decision-making. The observed increase in ED visits for device-related complications speaks to the need to improve preventive management to help mitigate emergency care after initiation of antegrade enemas.

RESUMEN

BACKGROUND: The 'normal appearing white matter' (NAWM) in multiple sclerosis (MS) is known to be abnormal using quantitative magnetic resonance (MR) techniques. The aetiology of the changes in NAWM remains debatable. OBJECTIVE: To investigate whether high-field and ultra high-field T(1)-weighted magnetization prepared rapid acquisition gradient echo (MPRAGE) MRI enables detection of MS white matter lesions in areas defined as NAWM using high-field T(2)-weighted fluid attenuation inversion recovery (FLAIR) MRI; that is, to ascertain whether undetected lesions are likely contributors to the burden of abnormality in similarly defined NAWM. METHODS: Fourteen MS patients underwent MRI scans using 3T FLAIR and MPRAGE and 7 Tesla (7T) MPRAGE sequences. Independent observers identified lesions on 3T FLAIR and (7T and 3T) MPRAGE images. The detection of every individual lesion was then compared for each image type. RESULTS: We identified a total of 812 white matter lesions on 3T FLAIR. Using 3T MPRAGE, 186 additional lesions were detected that were not detected using 3T FLAIR. Using 7T MPRAGE, 231 additional lesions were detected that were not detected using 3T FLAIR. CONCLUSIONS: MRI with 3T and 7T MPRAGE enables detection of MS lesions in areas defined as NAWM using 3T FLAIR. Focal MS lesions contribute to the abnormalities known to exist in the NAWM.

RESUMEN

BACKGROUND: Bladder and bowel dysfunction (BBD) is a common pediatric problem that describes a constellation of lower urinary tract symptoms associated with constipation and/or encopresis. Its association with neurodevelopmental and psychiatric (NDP) problems is not well understood. OBJECTIVES: Our primary aim was to identify pre-existing NDP disorders in children with BBD. Secondarily, we aimed to screen for new behavioral problems and evaluate the association between bladder or bowel symptoms and behaviors symptoms. METHODS: A cross sectional study was conducted in urology clinics. New patients referred for BBD between 4 and 17 years old were recruited and completed: a demographics survey, Dysfunctional Voiding Score System questionnaire, assessment of bowel movements with the Bristol Stool Scale, and Strength and Difficulties questionnaire (SDQ). Those with known spinal dysraphism were excluded. SDQ scores were evaluated for abnormal screens in different subscales and total difficulties scores. Pearson correlation analyses were conducted for association. RESULTS: We included 61 participants (age 9.5 ± 4.1 years), including 33 females and 28 males. One or more pre-existing NDP disorder(s) was reported in 14 (23%) children; most commonly being learning disability (43%) and attention deficit hyperactivity disorder (29%). This cohort had more severe BBD symptoms as reflected in DVSS scores. SDQ scores demonstrated that 12 patients without pre-existing NDP diagnoses scored in the clinical range, with hyperactivity as the most common difficulty (6/12; 50%). CONCLUSIONS: A significant proportion of children with BBD have a comorbid NDP disorder and present with more severe symptomatology. The SDQ can be used as a behavioral screening tool this population for the identification of children who may benefit from formal developmental pediatrics assessment.

RESUMEN

Lower urinary tract symptoms with constipation characterize bladder and bowel dysfunction (BBD). Due to high referral volumes to hospital pediatric urology clinics and time-consuming appointments, wait times are prolonged. Initial management consists of behavioral modification strategies that could be accomplished by community pediatricians. We aimed to create a network of community pediatricians trained in BBD (BBDN) management and assess its impact on care. METHODS: We distributed a survey to pediatricians, and those interested attended training consisting of lectures and clinical shadowing. Patients referred to a hospital pediatric urology clinic were triaged to the BBDN and completed the dysfunctional voiding symptom score and satisfaction surveys at baseline and follow-up. The Bristol stool chart was used to assess constipation. Results were compared between BBDN and hospital clinic patients. RESULTS: Surveyed pediatricians (n = 100) most commonly managed BBD with PEG3350 and dietary changes and were less likely to recommend bladder retraining strategies. Baseline characteristics were similar in BBDN (n = 100) and hospital clinic patients (n = 23). Both groups had similar improvements in dysfunctional voiding symptom score from baseline to follow-up (10.1 ± 4.2 to 5.6 ± 3.3, P = 0.01, versus 10.1 ± 4.2 to 7.8 ± 4.5, P = 0.02). BBDN patients waited less time for their follow-up visit with 56 (28-70) days versus 94.5 (85-109) days for hospital clinic patients (P < 0.001). Both groups demonstrated high familial satisfaction. CONCLUSIONS: Community pediatricians may require more knowledge of management strategies for BBD. Our pilot study demonstrates that implementing a BBDN is feasible, results in shorter wait times, and similar improvement in symptoms and patient satisfaction than a hospital pediatric urology clinic.

RESUMEN

Handover is defined as the communication of information between individuals and teams of healthcare providers to support the transfer of patient care and maintain professional responsibility and accountability. Poor handovers are increasingly recognized as potentially dangerous for patient safety and are associated with adverse events. One suggested method to improve the timely and efficient exchange of clinical information at handover and to reduce discontinuities in care is through the use of a minimum data set (MDS). The objective of this study was to describe the process of developing a single comprehensive hospital-wide MDS, created through an analysis of current handover processes and customary information tools used to support physician handover (MDHO) at a large quaternary care pediatric academic health sciences centre. A 20-item questionnaire was administered in person to a senior resident or fellow on each of 49 services identified to objectively assess MDHO processes, including frequency, consistency, format, participants and duration, for each service. The presence, type, location, responsibility for updating and security characteristics of MDHO tools used to support MDHO were also analyzed. The MDHO tools currently in use were collected and analyzed to create a comprehensive cross-institutional MDS. The analysis indicates that MDHO is highly consistent in terms of frequency, processes, participants, duration and the use of written tools to guide information exchange across departments. However, many best practice recommendations for MDHO are not being followed. Further, many of the existing MDHO tools in use have a similar content structure and already contain a majority of the components of a comprehensive MDS. Current local consistency in practice will allow for improved acceptance and adoption of an MDHO tool that continues to meet the clinical and administrative needs of physicians but also addresses needs for data accuracy and security. These additional specifications can be met through the use of information communication technologies.

RESUMEN

INTRODUCTION: The concepts of fragility index (FI) and fragility quotient (FQ) have been previously described. PlumX metrics encompass online "footprints" of research in addition to traditional citations. Herein we explore PlumX metrics against the quality of BBD literature. OBJECTIVE: To explore altmetrics against the quality of bladder and bowel dysfunction (BBD) literature. STUDY DESIGN: A literature search was conducted using Pubmed, Medline, Embase for BBD and related terms. A total of 54,045 abstracts were screened, followed by 693 full text reviews and data extraction from 126. Studies were included if they reported on 2 groups being compared, had dichotomous outcomes, and had significant results. RESULTS: The median FI score was 4 (0-500) and there were 20 studies which had a FI of 0. The FQ had a median of 0.04 (0-0.32). PlumX usage was 263 ± 540, captures were 45 ± 60 and social media attention was 2 ± 2. Overall, 42% of papers were clinical trials (RCTs). When compared to other study designs, we noted a significant difference in PlumX captures (57 ± 72 RCT vs. 35 ± 47 other; p = 0.03). RCTs had higher usage, social media engagement and citations however, the differences were not significant. H-Index had a significant correlation with FI (p = 0.036), however correlations for PlumX usage and captures, while modestly positive (0.04-0.10) for the FI and FQ, were not significant. A comparison of FI and FQ by topic can be reviewed in the Summary Table. DISCUSSION: When considering the FI and FQ robustness indicators of the BBD literature, we found similarities when compared to other studies. It was reported that overall, the hydronephrosis literature was fragile with many studies requiring only a few events to nullify significance, regardless of the study design. Similarly, in a review of pediatric vesicoureteral reflux (VUR) clinical trials, results were also fragile. When comparing fragility measures to altmetric variables we noted that despite the growing popularity of altmetrics, citation counts, and h-indices remain the traditional measures to monitor research consumption. There has been a reported correlation between manuscript citation counts, author h-index, altmetrics measures in several specialties and across many domains of research including medical sciences, arts, and the humanities, however in the present study only weak correlations were noted. CONCLUSION: The body of BBD comparative studies is fragile in keeping with other pediatric urology literature populations. Despite fragile results, RCTs generate slightly moreattention as measured by select PlumX metrics. These results suggest the need for including fragility measures in our literature, aiming to focus attention towards more robust articles.

RESUMEN

There are many neurological manifestations of thyroid disease, and thyroid function has taken its place in the "routine bloods" of neurology practice. However, although conditions such as carpal tunnel syndrome prompt thyroid testing despite any clear evidence for this approach, other symptoms of potential significance in terms of thyroid disease may be overlooked in the busy general neurology clinic, or abnormal thyroid tests may be assumed to be incidental. Psychiatric disorders, loss of consciousness, movement disorders and weakness may all be manifestations of primary thyroid disease. This is a symptom-based review where we will consider the evidence (or lack of it) for the association of various neurological problems with thyroid dysfunction, and also the pitfalls in interpretation of the biochemical tests.

RESUMEN

INTRODUCTION: Despite standardized neonatal resuscitation program (NRP) training, retention and adherence to the NRP algorithm remain a challenge. Cognitive aids can potentially improve acquisition and application of NRP knowledge and skills. The objective of this study was to determine whether an interactive mobile application providing audiovisual prompts, NRP Prompt, can help novice NRP providers learn the NRP algorithm more effectively and therefore improve their NRP performance. METHODS: First- and second-year residents from family medicine and obstetrics and gynecology attending NRP training were randomized into intervention and control groups. Resident pairs used standard visual aids with NRP Prompt (intervention) or visual aids only (control) in two simulated neonatal resuscitation training sessions with each resident taking turns as a team leader. Pairs were then evaluated in a third simulation that was video recorded, where neither group used cognitive aids. The primary outcome was comparing resuscitation performance. Secondary outcomes included the following: times to positive-pressure ventilation, intubation, and chest compressions. RESULTS: Thirty-nine residents participated, of which 18 received the intervention. Neonatal resuscitation program performance scores did not significantly differ (P = 0.69). Wilcoxon rank-sum tests showed no significant differences in secondary outcomes of times to positive-pressure ventilation (P = 0.43), intubation (P = 0.44), or chest compressions (P = 0.35). CONCLUSIONS: Training using NRP Prompt did not improve performance scores in simulated neonatal resuscitations immediately after training. Potential reasons include voice prompts in their current format being distracting and lack of customizability to user preferences. Future development of prompting applications should apply a user-centered design approach to optimize the ability to meet end-user needs.
