The Caregiver Burden of Helmet Therapy following Endoscopic Strip Craniectomy: A Phenomenological Qualitative Study.

INTRODUCTION: This cohort study aimed to elucidate the caregiver burden of helmet therapy (HT), following endoscopic strip craniectomy (ESC) to treat craniosynostosis, in an effort to inform clinicians and future caregivers navigating this therapeutic option. METHODS: Fourteen caregivers of children with positional plagiocephaly (6) and craniosynostosis treated by ESC (8) undergoing HT at a single center were recruited via convenience sampling. Using a phenomenological qualitative approach, semi-structured interviews were conducted to understand the experience of HT for caregivers. Data collection and analysis were iterative and conducted until thematic saturation was reached. RESULTS: Emerging themes revealed five domains of caregiver burden: emotional, cognitive, physical, psychosocial, and financial. No caregiver felt the therapy was too burdensome to complete. Caregivers of both groups also expressed positive aspects of HT related to support from the team, the noninvasive nature of treatment, and the outcomes of therapy. Furthermore, caregivers report overall satisfaction with the process, stating willingness to repeat the treatment with subsequent children if required. CONCLUSION: HT is associated with five major domains of caregiver burden; however, none of the caregivers regret choosing this treatment option, nor was the burden high enough to encourage treatment cessation. This study will inform future prospective analyses that will quantify real-time caregiver burden throughout HT.

Effects of the COVID-19 pandemic on out-of-hospital cardiac arrest care in Detroit.

INTRODUCTION: In response to the COVID-19 pandemic in Detroit, an earlier termination of resuscitation protocol was initiated in March 2020. To characterize pre-hospital cardiac arrest careduring COVID-19 in Detroit, we analyzed out-of-hospital cardiac arrest (OHCA) rate of ROSC (return of spontaneous circulation) and patient characteristics before and during the COVID-19 pandemic. METHODS: OHCA data was analyzed between March 10th, 2020 - April 30th, 2020 and March 10th, 2019 - April 30th, 2019. ROSC, patient demographics, arrest location, initial rhythms, bystander CPR and field termination were compared before and during the pandemic. Descriptive statistics were utilized to compare arrest characteristics between years, and the odds of achieving vs. not achieving ROSC. 2020 vs. 2019 as a predictor for ROSC was assessed with logistic regression. RESULTS: 471 patients were included. Arrests increased to 291 during the pandemic vs. 180 in 2019 (62% increase). Age (mean difference + 6; 95% CI: +2.4 to +9.5), arrest location (nursing home OR = 2.42; 95% CI: 1.42-4.31; public place OR = 0.47; 95% CI: 0.25-0.88), BLS response (OR = 0.68; 95% CI: 0.47-0.99), and field termination of resuscitation (OR = 2.36; 95% CI: 1.36-4.07) differed significantly in 2020 compared to 2019. No significant difference was found in the confounder-adjusted odds of ROSC in 2020 vs 2019 (OR = 0.61; 95% CI: 0.34-1.11). CONCLUSION: OHCA increased by 62% during COVID-19 in Detroit, without a significant change in prehospital ROSC. The rate of ROSC remained similar despite the implementation of an early termination of resuscitation protocol in response to COVID-19.

ST Elevation in the COVID-19 Era: A Diagnostic Challenge.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 induces a marked prothrombotic state with varied clinical presentations, including acute coronary artery occlusions leading to ST-elevation myocardial infarction (STEMI). However, while STEMI on electrocardiogram (ECG) is not always associated with acute coronary occlusion, this diagnostic uncertainty should not delay cardiac catheterization. CASE REPORTS: We present 2 cases of patients with COVID-19 that presented with STEMI on ECG. While both patients underwent cardiac catheterization, a delay in time to intervention in the patient found to have acute coronary artery occlusion may have contributed to a poor outcome. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: These cases highlight the fact that while not all COVID-19 patients with STEMI on ECG will have acute coronary artery occlusions, there is continued need for prompt percutaneous coronary intervention during the severe acute respiratory syndrome coronavirus 2 pandemic.

2017 American Heart Association Focused Update on Adult Basic Life Support and Cardiopulmonary Resuscitation Quality: An Update to the American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care.

Cardiopulmonary resuscitation is a lifesaving technique for victims of sudden cardiac arrest. Despite advances in resuscitation science, basic life support remains a critical factor in determining outcomes. The American Heart Association recommendations for adult basic life support incorporate the most recently published evidence and serve as the basis for education and training for laypeople and healthcare providers who perform cardiopulmonary resuscitation.

A META-ANALYSIS OF COGNITIVE BEHAVIOR THERAPY AND MEDICATION FOR CHILD OBSESSIVE-COMPULSIVE DISORDER: MODERATORS OF TREATMENT EFFICACY, RESPONSE, AND REMISSION.

BACKGROUND: Individual randomized controlled trials (RCTs) have demonstrated the efficacy of cognitive behavioral therapy (CBT) and serotonin reuptake inhibitors (SRIs) for the treatment of youth with obsessive-compulsive disorder (OCD). Although meta-analyses have confirmed these results, there has been minimal examination of treatment moderators or an examination of treatment response and symptom/diagnostic remission for these two treatment types. The present report examined the treatment efficacy, treatment response, and symptom/diagnostic remission for youth with OCD receiving either CBT or SRIs relative to comparison conditions, and examined treatment moderators. METHOD: A comprehensive literature search identified 20 RCTs that met inclusion criteria, and produced a sample size of 507 CBT participants and 789 SRI participants. RESULTS: Random effects meta-analyses of CBT trials found large treatment effects for treatment efficacy (g = 1.21), treatment response (relative risk [RR] = 3.93), and symptom/diagnostic remission (RR = 5.40). Greater co-occurring anxiety disorders, therapeutic contact, and lower treatment attrition were associated with greater CBT effects. The number needed to treat (NNT) was three for treatment response and symptom/diagnostic remission. Random effects meta-analyses of SRI trials found a moderate treatment effect for treatment efficacy (g = 0.50), treatment response (RR = 1.80), and symptom/diagnostic remission (RR = 2.06). Greater methodological quality was associated with a lower treatment response for SRI trials. The NNT was five for treatment response and symptom/diagnostic remission. CONCLUSIONS: Findings demonstrate the treatment effects for CBT and SRIs across three important outcome metrics, and provide evidence for moderators of CBT across trials.

"I am the doctor": gender-based bias within the clinical practice of emergency medicine in Canada-a thematic analysis of physician and trainee interview data.

OBJECTIVES: While women comprise about half of current Canadian medical students and physicians, only 31% of emergency medicine physicians identify as women and women trainees are less likely to express interest in emergency medicine compared to men. Gender-based bias continues to negatively impact the career choice, progress, and well-being of women physicians/trainees. Although instances of gender-based bias are well documented within other medical specialties, there remains a gap in the literature addressing the role of gender specific to the Canadian emergency medicine clinical environment. METHODS: Using a qualitative study with a thematic analytical approach, participants were purposively and snowball sampled from a cross-section of centers across Canada and included emergency medicine attending physicians and trainees. A thematic analysis using an inductive and deductive approach was undertaken. All data were double coded to improve study trustworthiness. Descriptive statistics were used to characterize the study population. RESULTS: Thirty-four individuals (17 woman-identifying and 17 man-identifying) from 10 different institutions across 4 provinces in Canada participated in the study. Six themes were identified: (1) women experience gender bias in the form of microaggressions; (2) women experience imposter syndrome and question their role in the clinical setting; (3) more women provide patient care to women patients and vulnerable populations; (4) gender-related challenges with family planning and home responsibilities affect work-life balance; (5) allyship and sponsorship are important for the support and development of women physicians and trainees; and (6) women value discussing shared experiences with other women to debrief situations, find mentorship, and share advice. CONCLUSIONS: Gender inequity in emergency medicine affects women-identifying providers at all levels of training across Canada. Described experiences support several avenues to implement change against perceived gender bias that is focused on education, policy, and supportive spaces. We encourage institutions to consider these recommendations to achieve gender-equitable conditions in emergency medicine across Canada.

ABSTRAIT: OBJECTIFS: Bien que les femmes représentent environ la moitié des étudiants et des médecins en médecine au Canada, seulement 31 % des médecins d'urgence qui s'identifient comme des femmes et des femmes stagiaires sont moins susceptibles d'exprimer leur intérêt pour la médecine d'urgence que les hommes. Les préjugés fondés sur le sexe continuent d'avoir une incidence négative sur le choix de carrière, les progrès et le bien-être des femmes médecins/stagiaires. Bien que les cas de biais fondés sur le sexe soient bien documentés dans d'autres spécialités médicales, il reste une lacune dans la documentation traitant du rôle du sexe propre au milieu clinique de la médecine d'urgence au Canada. MéTHODES: À l'aide d'une étude qualitative avec une approche analytique thématique, les participants ont été échantillonnés à dessein et en boule de neige dans un échantillon représentatif de centres à travers le Canada et comprenaient des médecins urgentistes et des stagiaires. Une analyse thématique utilisant une approche inductive et déductive a été entreprise. Toutes les données ont été codées en double pour améliorer la fiabilité de l'étude. Des statistiques descriptives ont été utilisées pour caractériser la population étudiée. RéSULTATS: Trente-quatre personnes (17 femmes et 17 hommes) de 10 établissements différents de quatre provinces canadiennes ont participé à l'étude. Six thèmes ont été cernés : (1) les femmes sont victimes de préjugés sexistes sous la forme de microagressions; (2) les femmes sont victimes du syndrome d'imposteur et remettent en question leur rôle dans le milieu clinique; (3) plus de femmes prodiguent des soins aux patientes et aux populations vulnérables; (4) les défis liés au genre que posent la planification familiale et les responsabilités familiales ont une incidence sur l'équilibre entre le travail et la vie personnelle; (5) l'alliance et le parrainage sont importants pour le soutien et le perfectionnement des femmes médecins et stagiaires; (6) les femmes apprécient de discuter des expériences partagées avec d'autres femmes pour faire le point sur des situations, trouver du mentorat et partager des conseils. CONCLUSIONS: L'inégalité entre les sexes en médecine d'urgence touche les fournisseurs de soins qui identifient les femmes à tous les niveaux de formation au Canada. Les expériences décrites appuient plusieurs avenues pour mettre en œuvre des changements contre les préjugés sexistes perçus qui sont axés sur l'éducation, les politiques et les espaces de soutien. Nous encourageons les établissements à tenir compte de ces recommandations afin de parvenir à des conditions équitables entre les sexes en médecine d'urgence partout au Canada.

The Impact of Just-in-Time Simulation Training for Healthcare Professionals on Learning and Performance Outcomes: A Systematic Review.

ABSTRACT: Although just-in-time training (JIT) is increasingly used in simulation-based health professions education, its impact on learning, performance, and patient outcomes remains uncertain. The aim of this study was to determine whether JIT simulation training leads to improved learning and performance outcomes. We included randomized or nonrandomized interventional studies assessing the impact of JIT simulation training (training conducted in temporal or spatial proximity to performance) on learning outcomes among health professionals (trainees or practitioners). Of 4077 citations screened, 28 studies were eligible for inclusion. Just-in-time training simulation training has been evaluated for a variety of medical, resuscitation, and surgical procedures. Most JIT simulation training occurred immediately before procedures and lasted between 5 and 30 minutes. Despite the very low certainty of evidence, this systematic review suggests JIT simulation training can improve learning and performance outcomes, in particular time to complete skills. There remains limited data on better patient outcomes and collateral educational effects.

Current use of simulation for EPA assessment in emergency medicine.

OBJECTIVE: Approximately five years ago, the Royal College emergency medicine programs in Canada implemented a competency-based paradigm and introduced the use of Entrustable Professional Activities (EPAs) for assessment of units of professional activity to assess trainees. Many competency-based medical education (CBME) based curricula, involve assessing for entrustment through observations of EPAs. While EPAs are frequently assessed in clinical settings, simulation is also used. This study aimed to characterize the use of simulation for EPA assessment. METHODS: A study interview guide was jointly developed by all study authors and followed best practices for survey development. A national interview was conducted with program directors or assistant program directors across all the Royal College emergency medicine programs across Canada. Interviews were conducted over Microsoft Teams, interviews were recorded and transcribed, using Microsoft Teams transcribing service. Sample transcripts were analyzed for theme development. Themes were then reviewed by co-authors to ensure they were representative of the participants' views. RESULTS: A 64.7% response rate was achieved. Simulation has been widely adopted by EM training programs. All interviewees demonstrated support for the use of simulation for EPA assessment for many reasons, however, PDs acknowledged limitations and thematic analysis revealed certain themes and tensions for using simulation for EPA assessment. Thematic analysis revealed six major themes: widespread support for the use of simulation for EPA assessment, concerns regarding the potential for EPA assessment to become a "tick- box" exercise, logistical barriers limiting the use of simulation for EPA assessment, varied perceptions about the authenticity of using simulation for EPA assessment, the potential for simulation for EPA assessment to compromise learner psychological safety, and suggestions for the optimization of use of simulation for EPA assessment. CONCLUSIONS: Our findings offer insight for other programs and specialties on how simulation for EPA assessment can best be utilized. Programs should use these findings when considering using simulation for EPA assessment.

RéSUMé: OBJECTIF: Il y a environ cinq ans, les programmes de médecine d'urgence du Collège royal au Canada ont mis en place un paradigme basé sur les compétences et ont introduit l'utilisation d'activités professionnelles confiables (APC) pour l'évaluation des unités d'activité professionnelle afin d'évaluer les stagiaires. De nombreux programmes d'enseignement médical basés sur les compétences (CBME) prévoient l'évaluation des compétences par l'observation des APC. Bien que les APC soient fréquemment évaluées en milieu clinique, la simulation est également utilisée. Cette étude visait à caractériser l'utilisation de la simulation pour l'évaluation de l'APC. MéTHODES: Un guide d'entretien d'étude a été élaboré conjointement par tous les auteurs de l'étude et a suivi les meilleures pratiques en matière d'élaboration d'enquêtes. Un entretien national a été réalisé avec les directeurs de programmes ou les directeurs adjoints de tous les programmes de médecine d'urgence du Collège royal au Canada. Les entretiens ont été menés sur Microsoft Teams, enregistrés et transcrits à l'aide du service de transcription de Microsoft Teams. Les transcriptions des échantillons ont été analysées pour développer des thèmes. Les thèmes ont ensuite été revus par les co-auteurs pour s'assurer qu'ils étaient représentatifs des points de vue des participants. RéSULTATS: Un taux de réponse de 64,7 % a été obtenu. La simulation a été largement adoptée par les programmes de formation en médecine d'urgence. Toutes les personnes interrogées se sont montrées favorables à l'utilisation de la simulation pour l'évaluation de l'APE pour de nombreuses raisons. Cependant, les DP ont reconnu des limites et l'analyse thématique a révélé certains thèmes et tensions liés à l'utilisation de la simulation pour l'évaluation de l'APC. L'analyse thématique a révélé six thèmes majeurs : un appui généralisé à l'utilisation de la simulation pour l'évaluation de l'APC, inquiétudes concernant la possibilité que l'évaluation de l'APC devienne un exercice de type « case à cocher ¼, des obstacles logistiques limitant l'utilisation de la simulation pour l'évaluation de l'APC, les perceptions variées quant à l'authenticité de l'utilisation de la simulation pour l'évaluation de l'APC, le potentiel de la simulation pour l'évaluation de l'APC de compromettre la sécurité psychologique des apprenants, et des suggestions pour l'optimisation de l'utilisation de la simulation pour l'évaluation de l'APC. CONCLUSIONS: Nos résultats offrent un aperçu à d'autres programmes et spécialités sur la meilleure façon d'utiliser la simulation pour l'évaluation de l'APC. Les programmes devraient utiliser ces résultats lorsqu'ils envisagent d'utiliser la simulation pour l'évaluation de l'APC.

Brief youth self-report screener for tics: Can a subscale of the Motor tic, Obsession and compulsion, and Vocal tic Evaluation Survey (MOVES) identify tic disorders in youth?

Tics are unwanted, repetitive movements and sounds that frequently present during childhood. They are typically brief and purposeless, but can create significant distress for individuals, and often co-occur with other neuropsychiatric conditions. Thus, early identification of tics is warranted. Unfortunately, tics are often misdiagnosed, and because tics may wax and wane, identification can be difficult, especially in the context of routine clinical visits. There are limited tools that can be used to reliably identify tics in clinical practice, especially in non-specialty settings. The purpose of the current study was to evaluate the performance of the Motor tic, Obsession and compulsion, and Vocal tic Evaluation Survey (MOVES), a self-report scale with some support as a screening tool. In addition, the performance of a subset of questions (the MOVES-6) was evaluated for rapid screening. Participants were recruited across two study sites and included children and adolescents diagnosed with Tourette syndrome (n = 151) or another persistent tic disorder (n = 10) and community controls (n = 74). Results suggest both the MOVES and the MOVES-6 have high sensitivity (90% and 88%, respectively) and at least acceptable specificity (77% and 86%, respectively) compared with expert assessment of tic disorders, suggesting that both versions can identify tic disorders without high proportions of false negatives. Both versions were highly sensitive with acceptable specificity regardless of sex, race/ethnicity, and age. The MOVES and MOVES-6 show promise as a screener for tics or tic disorders, but additional research is needed, particularly in a general population setting.

Helping boys at-risk of criminal activity: qualitative results of a multi-component intervention.

BACKGROUND: This qualitative study examines parent and child experiences of participation in a multi-component community-based program aimed at reducing offending behaviour, and increasing social competence in boys 6 to 11 years old in Hamilton, Ontario, Canada. The program builds on the concept of crime prevention through social development, and includes structured groups for the identified boy, parents, and siblings. METHODS: A sample of 35 families participating in the multi-component program took part in the qualitative study. Individual interviews with the boys, parents and siblings asked about changes in themselves, relationships with family and peers, and school after the group. Interviews were taped, transcribed and content analysis was used to code and interpret the data. RESULTS: Parents reported improvement in parenting skills and attainment of more effective communication skills, particularly with their children. Parents also found the relationships they formed with other parents in the program and the advice that they gained to be beneficial. Boys who participated in the program also benefited, with both parents and boys reporting improvements in boys' anger management skills, social skills, impulse control, and ability to recognize potentially volatile situations. Both parents and boys described overall improvement in family relationships and school-related success. CONCLUSIONS: The qualitative data revealed that parents and boys participating in the multi-component program perceived improvements in a number of specific areas, including social competence of the boys. This has not been demonstrated as clearly in other evaluations of the program.

Factors Associated With Voluntary Refusal of Emergency Medical System Transport for Emergency Care in Detroit During the Early Phase of the COVID-19 Pandemic.

Importance: Emergency department (ED) and emergency medical services (EMS) volumes decreased during the COVID-19 pandemic, but the amount attributable to voluntary refusal vs effects of the pandemic and public health restrictions is unknown. Objective: To examine the factors associated with EMS refusal in relation to COVID-19 cases, public health interventions, EMS responses, and prehospital deaths. Design, Setting, and Participants: A retrospective cohort study was conducted in Detroit, Michigan, from March 1 to June 30, 2020. Emergency medical services responses geocoded to Census tracts were analyzed by individuals' age, sex, date, and community resilience using the Centers for Disease Control and Prevention Social Vulnerability Index. Response counts were adjusted with Poisson regression, and odds of refusals and deaths were adjusted by logistic regression. Exposures: A COVID-19 outbreak characterized by a peak in local COVID-19 incidence and the strictest stay-at-home orders to date, followed by a nadir in incidence and broadly lifted restrictions. Main Outcomes and Measures: Multivariable-adjusted difference in 2020 vs 2019 responses by incidence rate and refusals or deaths by odds. The Social Vulnerability Index was used to capture community social determinants of health as a risk factor for death or refusal. The index contains 4 domain subscores; possible overall score is 0 to 15, with higher scores indicating greater vulnerability. Results: A total of 80 487 EMS responses with intended ED transport, 2059 prehospital deaths, and 16 064 refusals (62 636 completed EMS to ED transports) from 334 Census tracts were noted during the study period. Of the cohort analyzed, 38 621 were women (48%); mean (SD) age was 49.0 (21.4) years, and mean (SD) Social Vulnerability Index score was 9.6 (1.6). Tracts with the highest per-population EMS transport refusal rates were characterized by higher unemployment, minority race/ethnicity, single-parent households, poverty, disability, lack of vehicle access, and overall Social Vulnerability Index score (9.6 vs 9.0, P = .002). At peak COVID-19 incidence and maximal stay-at-home orders, there were higher total responses (adjusted incident rate ratio [aIRR], 1.07; 1.03-1.12), odds of deaths (adjusted odds ratio [aOR], 1.60; 95% CI, 1.20-2.12), and refusals (aOR, 2.33; 95% CI, 2.09-2.60) but fewer completed ED transports (aIRR, 0.82; 95% CI, 0.78-0.86). With public health restrictions lifted and the nadir of COVID-19 cases, responses (aIRR, 1.01; 0.97-1.05) and deaths (aOR, 1.07; 95% CI, 0.81-1.41) returned to 2019 baselines, but differences in refusals (aOR, 1.27; 95% CI, 1.14-1.41) and completed transports (aIRR, 0.95; 95% CI, 0.90-0.99) remained. Multivariable-adjusted 2020 refusal was associated with female sex (aOR, 2.71; 95% CI, 2.43-3.03 in 2020 at the peak; aOR 1.47; 95% CI, 1.32-1.64 at the nadir). Conclusions and Relevance: In this cohort study, EMS transport refusals increased with the COVID-19 outbreak's peak and remained elevated despite receding public health restrictions, COVID-19 incidence, total EMS responses, and prehospital deaths. Voluntary refusal was associated with decreased EMS transports to EDs, disproportionately so among women and vulnerable communities.

Incidence and predictors of adherence to sleep apnea treatment in rehabilitation inpatients with acquired brain injury.

OBJECTIVE: The purpose of this study was to describe incidence and assess predictors of adherence to Positive Airway Pressure (PAP) therapy for Obstructive Sleep Apnea (OSA) in persons with acquired brain injury (ABI). METHODS: A 2012-2015 retrospective analysis of consecutive ABI patients admitted for neurorehabilitation, referred for polysomnography (PSG), and prescribed PAP for OSA. Univariable linear regressions were conducted to examine predictors of average hours of nightly PAP use. Univariable logistic regressions were conducted to examine predictors of PAP adherence using the conventional clinical definition of ≥4 h per night ≥70% of the time. Persons with traumatic etiology were separately analyzed. RESULTS: ABI etiology was 51% traumatic, 36% stroke, and 13% other nontraumatic causes. Nearly two-thirds were nonadherent to PAP. For the overall sample, higher average nightly PAP usage was significantly predicted by positive hypertension diagnosis (ß = 0.271, p = 0.019). Likewise, greater adherence based on the conventional cutoff was predicted by poorer motor functioning at hospital admission (OR = 0.98, p = 0.001) and lower oxygen saturation nadir (OR = 0.99, p = 0.003). For those with traumatic injuries, greater adherence was predicted by poorer functional status at hospital admission (OR = 0.98, p = 0.010) and positive hypertension diagnosis (OR = 0.16, p = 0.023). CONCLUSIONS: In this study of hospitalized neurorehabilitation patients with ABI and comorbid OSA, predictors of adherence included lower oxygen saturation, poorer functional status and hypertension diagnosis, perhaps signifying the role of greater severity of illness on treatment adherence. High rates of refusal and nonadherence to frontline PAP therapy for sleep apnea is a concern for persons in recovery form ABI who are at a time of critical neural repair.

Anabolic Androgenic Steroid Use as a Cause of Fulminant Heart Failure.

A 39-year-old male weightlifter presented in fulminant heart failure. An echocardiogram revealed severe global biventricular failure. Left ventricular (LV) systolic function was estimated at 15%. His dilated cardiomyopathy was attributed to his use of both testosterone and boldenone in the 3-month period before his presentation. Although the deleterious effects of androgenic- anabolic steroids on diastolic function are well known, the effects of these drugs on systolic function is an area of ongoing investigation. Our case suggests that androgenic anabolic steroid use should be considered in the differential diagnosis of patients presenting with acute heart failure.

Improvement in Non-Traumatic, Out-Of-Hospital Cardiac Arrest Survival in Detroit From 2014 to 2016.

Background In 2002, the out-of-hospital cardiac arrest ( OHCA ) survival rate in Detroit was the lowest in the nation. Concerted efforts sought to improve the city's chain of survival with a focus on emergency medical services ( EMS ). This study assesses the impact on OHCA survival rates and describe factors associated with survival. Methods and Results Data for non-traumatic OHCA cases in Detroit from 2014 to 2016 were extracted from CARES (Cardiac Arrest Registry to Enhance Survival). Chi-squared tests, non-parametric tests, and a multivariable logistic regression analysis were employed to examine the associations between overall survival and its covariates. A total of 2359 non-traumatic OHCA cases were examined. The overall survival rate increased from 3.7% in 2014 to 5.4% in 2015, and 6.4% in 2016 ( P<0.01), reflecting a 73% improvement in survival over the 3-year period. EMS median on-scene time decreased over the study period, while the rate at which EMS initiated cardiopulmonary resuscitation and applied an automated external defibrillator (AED) greatly increased ( P<0.001). The factors significantly associated with survival were female sex (odds ratio=1.70, P<0.05), a public setting (odds ratio=2.31, P<0.01), an EMS witness (odds ratio=6.18, P<0.01), and the presence of an initial shockable rhythm (odds ratio=1.88, P<0.05). Conclusions From 2014 to 2016, the overall survival rate for OHCA patients in Detroit, MI significantly improved. Our results suggest that an improved chain of survival may explain this progress. This study is an example of how OHCA data analysis and EMS improvement can improve end OHCA outcomes in a resource-limited urban setting.

A Double-Blind Randomized Placebo-Controlled Pilot Study of Azithromycin in Youth with Acute-Onset Obsessive-Compulsive Disorder.

OBJECTIVES: Sudden and severe onset of obsessive-compulsive disorder (OCD) may present secondary to infectious and/or immune-mediated triggers. We assessed the preliminary efficacy, tolerability, and safety of azithromycin compared with placebo in the treatment of OCD and associated symptoms in children with pediatric acute-onset neuropsychiatric syndrome (PANS). METHODS: Thirty-one youth aged 4-14 years (M = 8.26 ± 2.78 years, 62.5% male) were randomized to receive either placebo or azithromycin for 4 weeks (10 mg/kg up to 500 mg per day). Both groups were administered twice daily probiotics. The primary outcome, obsessive-compulsive symptom severity, was assessed using the OCD Clinical Global Impressions Severity (CGI-S OCD) and Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS). RESULTS: Participants in the azithromycin group (n = 17) showed significantly greater reductions in OCD severity on the CGI-S OCD than the placebo group (n = 14) posttreatment (p = 0.003), although there were no significant differences on the CY-BOCS. Significantly more participants in the azithromycin condition met treatment responder criteria on the CGI-I OCD at the end of week 4 (41.2%, n = 7) in comparison to the placebo group (7.1%, n = 1; p = 0.045). Tic severity moderated treatment response, with greater tic severity being associated with enhanced treatment response on the CGI-S OCD. Azithromycin was well tolerated with minimal adverse effects and no study dropouts due to side effects. However, the azithromycin group showed a trend toward significantly greater electrocardiography QTc (p = 0.060) at the end of week 4, and significantly more reports of loose or abnormal stools (p = 0.009). CONCLUSION: This double blind pilot study suggests that azithromycin may be helpful in treating youth meeting the PANS diagnosis, especially those with elevated levels of both OCD and tic symptoms. Azithromycin was well tolerated, but the potential for cardiac risks suggests that additional monitoring may be needed to ensure safety.

Accuracy of instructor assessment of chest compression quality during simulated resuscitation.

OBJECTIVES: The 2010 American Heart Association Guidelines stress the importance of high quality cardiopulmonary resuscitation (CPR) as a predictor of survival from cardiac arrest. However, resuscitation training is often facilitated and evaluated by instructors without access to objective measures of CPR quality. This study aims to determine whether instructors experienced in the area of adult resuscitation (emergency department staff and senior residents) can accurately assess the quality of chest compressions as a component of their global assessment of a simulated resuscitation scenario. METHODS: This is a prospective observational study in which objective chest compression quality data (rate, depth, and fraction) were collected from the simulation manikin and compared to subjective instructor assessment. Data were collected during weekly simulation training sessions for residents, medical students, and nursing students. RESULTS: We included data from 24 simulated resuscitation scenarios assessed by 1 of 15 instructors. Subjective assessment of chest compression quality identified an adequate compression rate (100-120 compressions per minute) with a sensitivity of 0.17 (confidence interval [CI] 0.02-0.32) and specificity of 0.06 (CI -0.04-0.15), adequate depth (>50 mm) with a sensitivity of 0 and specificity of 0.38 (CI 0.18-0.57), and adequate fraction (>80%) with a sensitivity of 1 and a specificity of 0.25 (CI 0.08-0.42). CONCLUSION: Instructor assessment of chest compression rate, depth, and fraction demonstrates poor sensitivity and specificity when compared to the data from the simulation manikin. These results support the use of objective and technologically supported measures of chest compression quality for feedback during resuscitation education using simulators.

A meta-analysis of behavior therapy for Tourette Syndrome.

Individual randomized controlled trials (RCTs) of habit reversal training and a Comprehensive Behavioral Intervention for Tics (collectively referred to as behavior therapy, BT) have demonstrated efficacy in reducing tic severity for individuals with Tourette Syndrome and Chronic Tic Disorders (collectively referred to as TS), with no examination of treatment moderators. The present meta-analysis synthesized the treatment effect sizes (ES) of BT relative to comparison conditions, and examined moderators of treatment. A comprehensive literature search identified eight RCTs that met inclusion criteria, and produced a total sample of 438 participants. A random effects meta-analysis found a medium to large ES for BT relative to comparison conditions. Participant mean age, average number of therapy sessions, and the percentage of participants with co-occurring attention deficit hyperactivity disorder (ADHD) were found to moderate treatment effects. Participants receiving BT were more likely to exhibit a treatment response compared to control interventions, and identified a number needed to treat (NNT) of three. Sensitivity analyses failed to identify publication bias. Overall, BT trials yield medium to large effects for TS that are comparable to treatment effects identified by meta-analyses of antipsychotic medication RCTs. Larger treatment effects may be observed among BT trials with older participants, more therapeutic contact, and less co-occurring ADHD.
