Early intranasal medication administration in out-of-hospital cardiac arrest: Two randomized simulation trials.

Objective: Intranasal medications have been proposed as adjuncts to out-of-hospital cardiac arrest (OHCA) care. We sought to quantify the effects of intranasal medication administration (INMA) in OHCA workflows. Methods: We conducted separate randomized OHCA simulation trials with lay rescuers (LRs) and first responders (FRs). Participants were randomized to groups performing hands-only cardiopulmonary resuscitation (CPR)/automated external defibrillator with or without INMA during the second analysis phase. Time to compression following the second shock (CPR2) was the primary outcome and compression quality (chest compression rate (CCR) and fraction (CCF)) was the secondary outcome. We fit linear regression models adjusted for CPR training in the LR group and service years in the FR group. Results: Among LRs, INMA was associated with a significant increase in CPR2 (mean diff. 44.1 s, 95% CI: 14.9, 73.3), which persisted after adjustment (p = 0.005). We observed a significant decrease in CCR (INMA 95.1 compressions per min (cpm) vs control 104.2 cpm, mean diff. -9.1 cpm, 95% CI -16.6, -1.6) and CCF (INMA 62.4% vs control 69.8%, mean diff. -7.5%, 95% CI -12.0, -2.9). Among FRs, we found no significant CPR2 delays (mean diff. -2.1 s, 95% CI -15.9, 11.7), which persisted after adjustment (p = 0.704), or difference in quality (CCR INMA 115.5 cpm vs control 120.8 cpm, mean diff. -5.3 cpm, 95% CI -12.6, 2.0; CCF INMA 79.6% vs control 81.2% mean diff. -1.6%, 95% CI -7.4, 4.3%). Conclusions: INMA in LR resuscitation was associated with diminished resuscitation performance. INMA by FR did not impede key times or quality.

Effectiveness of Lay Bystander Hands-Only Cardiopulmonary Resuscitation on a Mattress versus the Floor: A Randomized Cross-Over Trial.

STUDY OBJECTIVE: Bystander cardiopulmonary resuscitation increases the likelihood of out-of-hospital cardiac arrest survival by more than two-fold. A common barrier to the prompt initiation of compressions is moving victims to the floor, but compression quality on a "floor" versus a "mattress" has not been tested among lay bystanders. METHODS: We conducted a prospective, randomized, cross-over trial comparing lay bystander compression quality using a manikin on a bed versus the floor. Participants included adults without professional health care training. We randomized participants to the order of manikin placement, either on a mattress or on the floor. For both, participants were instructed to perform 2 minutes of chest compressions on a cardiopulmonary resuscitation Simon manikin Gaumard (Gaumard Scientific, Miami, FL). The primary outcome was mean compression depth (cm) over 2 minutes. We fit a linear regression model adjusted for scenario order, age, sex, and body mass index with robust standard errors to account for repeated measures and reported mean differences with 95% confidence intervals (CIs). RESULTS: Our sample of 80 adults was 66% female with a mean age of 50.5 years (SD 18.2). The mean compression depth on the mattress was 2.9 cm (SD 2.3) and 3.5 cm (SD 2.2) on the floor, a mean difference of 0.58 cm (95% CI 0.18, 0.98). Compression depth fell below the 5 to 6 cm depth recommended by the American Heart Association on both surfaces. In the adjusted model, the mean depth was greater when the manikin was on the floor than the mattress (adjusted mean difference 0.62 cm; 95% CI 0.23 to 1.01), and mean depth was less for females than males (adjusted mean difference -1.42 cm, 95% CI -2.59, -0.25). In addition, the difference in compression depth was larger for female participants (mean difference 0.94 cm; 95% CI 0.54, 1.34) than for male participants (mean difference -0.01 cm; 95% CI -0.80, 0.78), and the interaction was statistically significant (P = .04). CONCLUSION: The mean compression depth was significantly smaller on the mattress and with female bystanders. Further research is needed to understand the benefit of moving out-of-hospital cardiac arrest victims to the floor relative to the detrimental effect of delaying chest compressions.

Taking Stock and Looking Ahead: Evolution of Accreditation Feedback for Simulation Centers Over 8 Years Using Epistemic Network Analysis.

INTRODUCTION: Since 2005, the American College of Surgeons Accredited Educational Institutes has provided accreditation of surgically focused simulation centers with the added benefit of identifying best practices defined as areas far exceeding the accreditation standards or novel methods of advancing high-quality, impactful education. This study aimed to examine the evolution of the best practices observed by accreditors during site visits over the 8-year period. METHODS: Accreditation included the completion of an application form followed by a site visit by a simulation expert and review of all materials by an accreditation committee to identify areas out of compliance along with areas far exceeding accreditation standards. These are termed "best practices." To evaluate the evolution of accreditation feedback and embedded associations, the compiled list of 337 best practices identified from all 247 site visits over an 8-year period was analyzed and visualized using epistemic network analysis, a quantitative ethnographic technique for modeling the structure of connections in qualitative data. RESULTS: The overall association network of the data indicates that the strongest associations were between assessment, curriculum development, faculty development, research, and teaching methods, demonstrating a highly interconnected model of accreditation feedback. Best practices evolved from an early focus on teaching methods, faculty, and curriculum development to more advanced educational topics including assessment, research, resources, and overall center governance. Distribution of associations also increased over the 8-year period with more nuanced and interconnected statements demonstrating higher-level feedback including explanations, contributing factors, impact on other areas, and, in some cases, recommendations to share best practices outside the organization. CONCLUSIONS: The epistemic network analysis of this 8-year database of simulation center feedback provides a novel perspective on an organization and the evolving field of simulation from an optional to essential modality in healthcare professions education.

A multimedia paediatric cardiology assessment tool for medical students and general paediatric trainees: development and validation.

BACKGROUND: Understanding how cardiovascular structure and physiology guide management is critically important in paediatric cardiology. However, few validated educational tools are available to assess trainee knowledge. To address this deficit, paediatric cardiologists and fellows from four institutions collaborated to develop a multimedia assessment tool for use with medical students and paediatric residents. This tool was developed in support of a novel 3-dimensional virtual reality curriculum created by our group. METHODS: Educational domains were identified, and questions were iteratively developed by a group of clinicians from multiple centres to assess understanding of key concepts. To evaluate content validity, content experts completed the assessment and reviewed items, rating item relevance to educational domains using a 4-point Likert scale. An item-level content validity index was calculated for each question, and a scale-level content validity index was calculated for the assessment tool, with scores of ≥0.78 and ≥0.90, respectively, representing excellent content validity. RESULTS: The mean content expert assessment score was 92% (range 88-97%). Two questions yielded ≤50% correct content expert answers. The item-level content validity index for 29 out of 32 questions was ≥0.78, and the scale-level content validity index was 0.92. Qualitative feedback included suggestions for future improvement. Questions with ≤50% content expert agreement and item-level content validity index scores <0.78 were removed, yielding a 27-question assessment tool. CONCLUSIONS: We describe a multi-centre effort to create and validate a multimedia assessment tool which may be implemented within paediatric trainee cardiology curricula. Future efforts may focus on content refinement and expansion to include additional educational domains.

An approach to value-based simulator selection: The creation and evaluation of the simulator value index tool.

BACKGROUND: Currently there is no reliable, standardized mechanism to support health care professionals during the evaluation of and procurement processes for simulators. A tool founded on best practices could facilitate simulator purchase processes. METHODS: In a 3-phase process, we identified top factors considered during the simulator purchase process through expert consensus (n = 127), created the Simulator Value Index (SVI) tool, evaluated targeted validity evidence, and evaluated the practical value of this SVI. A web-based survey was sent to simulation professionals. Participants (n = 79) used the SVI and provided feedback. We evaluated the practical value of 4 tool variations by calculating their sensitivity to predict a preferred simulator. RESULTS: Seventeen top factors were identified and ranked. The top 2 were technical stability/reliability of the simulator and customer service, with no practical differences in rank across institution or stakeholder role. Full SVI variations predicted successfully the preferred simulator with good (87%) sensitivity, whereas the sensitivity of variations in cost and customer service and cost and technical stability decreased (≤54%). The majority (73%) of participants agreed that the SVI was helpful at guiding simulator purchase decisions, and 88% agreed the SVI tool would help facilitate discussion with peers and leadership. CONCLUSION: Our findings indicate the SVI supports the process of simulator purchase using a standardized framework. Sensitivity of the tool improved when factors extend beyond traditionally targeted factors. We propose the tool will facilitate discussion amongst simulation professionals dealing with simulation, provide essential information for finance and procurement professionals, and improve the long-term value of simulation solutions. Limitations and application of the tool are discussed.

Simulation center best practices: A review of ACS-accredited educational institutes' best practices, 2011 to present.

BACKGROUND: Since the inception of American College of Surgeons' Accredited Educational Institute (ACS-AEI) Consortium, accreditation reviews have identified best practices in simulation-based education and center operations. A review of best practices would support the communication of these best practices, offer recognition of exemplar institutes, and facilitate discussion and sharing of resources amongst AEIs. METHODS: We examined 5 years of ACS AEI accreditation best practices identified across all standards and criteria. The goal was to identify resources that could be shared among AEIs and recognize AEI champions that have promoted best practices in surgical simulation. RESULTS: From 149 site reviews (July 2011-June 2016), reviewers identified 197 best practices across 83 AEIs (52.9% of all sites reviewed received a best practice). A total of 52.5% of best practices were associated with curriculum development, delivery of effective education and assessment, and 25 available resources were identified that could be shared among AEIs. The majority of best practices (n = 117, 59.3%) were identified at 24 AEIs, with the highest number of best practices identified at Banner Simulation Center and New Orleans Learning Center (10 each over 2 reviews). Twenty-two other institutes presented 97 best practices, with between 3 to 8 per institute (mean = 4.4, standard deviation = 1.6). Specific best practices, criteria, and AEI champions are highlighted. CONCLUSION: Review of AEI accreditation best practices identified common themes for surgical simulation programs and identified tools that could be shared to advance all programs and champion AEIs that have promoted best practices in surgical simulation.

Institution-Specific Factors Associated With Family Medicine Residency Match Rates.

UNLABELLED: Phenomenon: Existing research provides little specific evidence regarding the association between public and private medical school curricular settings and the proportion of medical students matching into family medicine careers. Institutional differences have been inadequately investigated, as students who match into family medicine are often consolidated into the umbrella of primary care along with those matching in internal medicine and pediatrics. However, understanding medical school contexts in relation to career choice is critical toward designing targeted strategies to address the projected shortage of family physicians. This study examines factors associated with family medicine residency match rates and the extent to which such factors differ across medical school settings. APPROACH: We combined data from a survey of 123 departments of family medicine with graduate placement rates reported to the American Academy of Family Physicians over a 2-year period. Chi-square/Fisher's Exact texts, t tests, and linear regression analyses were used to identify factors significantly associated with average match rate percentages. FINDINGS: The resulting data set included 85% of the U.S. medical schools with Departments of Family Medicine that reported 2011 and 2012 residency match rates in family medicine. Match rates in family medicine were higher among graduates of public than private medical schools-11% versus 7%, respectively, t(92) = 4.00, p < .001. Using a linear regression model and controlling for institutional type, the results indicated 2% higher match rates among schools with smaller annual clerkship enrollments (p  = .03), 3% higher match rates among schools with clerkships lasting more than 3 to 4 weeks (p  = .003), 3% higher match rates at schools with at least 1 family medicine faculty member in a senior leadership role (p  = .04), and 8% lower match rates at private medical schools offering community medicine electives (p < .001, R(2) = .48), F(6, 64) = 9.95, p < .001. Three additional factors were less strongly related and varied by institutional type-informal mentoring, ambulatory primary care learning experiences, and institutional research focus. Insights: Educational opportunities associated with higher match rates in family medicine differ across private and public medical schools. Future research is needed to identify the qualitative aspects of educational programming that contribute to differences in match rates across institutional contexts. Results of this study should prove useful in mitigating physician shortages, particularly in primary care fields such as family medicine.

Otitis media: diagnosis and treatment.

Acute otitis media is diagnosed in patients with acute onset, presence of middle ear effusion, physical evidence of middle ear inflammation, and symptoms such as pain, irritability, or fever. Acute otitis media is usually a complication of eustachian tube dysfunction that occurs during a viral upper respiratory tract infection. Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis are the most common organisms isolated from middle ear fluid. Management of acute otitis media should begin with adequate analgesia. Antibiotic therapy can be deferred in children two years or older with mild symptoms. High-dose amoxicillin (80 to 90 mg per kg per day) is the antibiotic of choice for treating acute otitis media in patients who are not allergic to penicillin. Children with persistent symptoms despite 48 to 72 hours of antibiotic therapy should be reexamined, and a second-line agent, such as amoxicillin/clavulanate, should be used if appropriate. Otitis media with effusion is defined as middle ear effusion in the absence of acute symptoms. Antibiotics, decongestants, or nasal steroids do not hasten the clearance of middle ear fluid and are not recommended. Children with evidence of anatomic damage, hearing loss, or language delay should be referred to an otolaryngologist.

Applying health information technology and team-based care to residency education.

BACKGROUND AND OBJECTIVES: Training physicians capable of practicing within the Patient-centered Medical Home (PCMH) is an emerging area of scholarly inquiry within residency education. This study describes an effort to integrate PCMH principles into teaching practices within a university-based residency setting and evaluates the effect on clinical performance. METHODS: Using participant feedback and clinical data extracted from an electronic clinical quality management system, we retrospectively examined performance outcomes at two family medicine residency clinics over a 7-year period. Instructional approaches were identified and clinical performance patterns analyzed. RESULTS: Alumni ratings of the practice-based curriculum increased following institution of the PCMH model. Clinical performance outcomes indicated improvements in the delivery of clinical care to patients. Implementation of instructional methodologies posed some challenges to residency faculty, particularly in development of consistent scheduling of individualized feedback sessions. Residents required the greatest support and guidance in managing point-of-care clinical reminders during patient encounters. CONCLUSIONS: Teaching practices that take into consideration the integration of team-based care and use of electronic health technologies can successfully be used to deliver residency education in the context of the PCMH model. Ongoing assessment provides important information to residency directors and faculty in support of improving the quality of clinical instruction.

Simulation enhances resident confidence in critical care and procedural skills.

BACKGROUND: The goal of this study was to determine if clinical simulation improved resident confidence in performing critical care skills, neonatal resuscitation, and colonoscopy. METHODS: Residents participated in clinical simulations utilizing high-fidelity medical simulators in a realistic environment. We compared resident responses on pre- and post-experience surveys. RESULTS: Residents reported satisfaction with quality of demonstrations and opportunity for hands-on learning and practice. Residents felt more confident in their ability to apply these skills independently and in the applied context. CONCLUSIONS: Simulation is a well-accepted teaching method for critical care and procedural skills and improves resident confidence.
