Association of number of primary care physicians with preventable hospitalizations and premature deaths.

BACKGROUND: Primary care physicians (PCPs) may be the first providers for patients in a healthcare interaction, putting them in a unique position that may determine the health trajectory of a patient. Assessing whether PCPs improve the overall health of a community through reducing preventable hospital stays and premature deaths may provide necessary information towards improving the health outcomes at grassroots. METHODS: County-level data on the number of primary care physicians, preventable hospital stays and 'years of potential life lost' (YPLL) were obtained from the Physician Master File data of the American Medical Association, Centers for Medicare & Medicaid Services Office of Minority Health's Mapping Medicare Disparities data, and Center for Disease Control and Prevention's WONDER database, respectively. We employed linear regression model to assess the association of PCP rate with preventable hospital stays and YPLL. RESULTS: Preventable hospitalization rate in the United States was 6303.4 (95% CI, 6212.5-6394.3) hospitalizations per 100,00 population, while the average YPLL across the counties in the United States was 7792.9 (95% CI, 7697.6-7888.3) years per 100,000 population. For an increase of 1 PCP in a county, around 16 hospitalizations were prevented per 100,000 population (P = 0.001) each year. Furthermore, around 14 years of life were saved per 100,000 population for every additional PCP in a county across the United States (P < 0.001). CONCLUSION: Higher number of PCPs in a county was associated with lower hospitalizations for preventable causes and lower premature deaths. Increasing PCPs may be an important metric to improve overall health in a community.

A Randomized Single-Blinded Simulation-Based Trial of a Novel Method for Fluid Administration to a Septic Infant.

OBJECTIVES: For children presenting in shock, American College of Critical Care Medicine guidelines recommend 3 boluses of intravenous fluids during initial resuscitation, but these are often not met. This study aims to compare a novel device LifeFlow, to established manual methods for rapid fluid delivery in a simulated environment. METHOD: This single-blinded randomized trial was conducted in a level 1 pediatric trauma center emergency department. Fifty-four participants were paired and randomized to one of the following methods: push/pull, pressure bag, or LifeFlow. The teams were presented with a standardized simulation-based case and asked to resuscitate a 10-kg patient in decompensated shock. We used a demographic survey to study provider variables, recordings of the simulation and fluid delivery to independently establish rate and accuracy, and the National Aeronautical and Space Administration Task Load Index to assess workload. RESULT: All 54 participants completed the assigned tasks, and no significant differences were found among the demographics of participants. The primary outcome (mean rate of fluid administration) differed significantly between the 3 techniques, LifeFlow being the fastest (65.29 mL/min). The composite National Aeronautical and Space Administration Task Load Index score (30; P = 0.184) was lowest for the LifeFlow. Significant differences were seen among the correlation coefficient comparing the estimated to the actual volume of fluid for each method, pressure bag being the highest (0.66), followed by push-pull (0.54) and LifeFlow (0.31). CONCLUSIONS: LifeFlow allowed for faster fluid administration rate and thus could be the preferred technique for rapid fluid resuscitation in pediatrics patients. Further investigations should explore the reproducibility of these results using this device in real patients in multiple centers.

Sexual Assault in an Adolescent Female: A Pediatric Simulation Case for Emergency Medicine Providers.

Introduction: Many emergency medicine (EM) physicians have limited training in the care of sexual assault patients. Simulation is an effective means to increase the confidence and knowledge of physicians in such high-stakes, low-frequency clinical scenarios as sexual assault. We sought to develop and implement a sexual assault simulation with a structured debriefing for EM residents and to determine its impact on resident learners' attitudes and knowledge skills in the care of patients with sexual assault. Methods: The simulation blended psychomotor skills (e.g., collecting forensic evidence), cognitive skills (e.g., ordering laboratory studies and medications), and communication skills (e.g., obtaining relevant patient history, responding to psychosocial concerns raised by team members and simulator). Our emergency department checklist was available as a cognitive aid for each step of the evidence collection process. A content expert answered questions in real time during the simulation and provided structured debriefing following the simulation. Trainees completed an anonymous survey within a week after the intervention and a follow-up survey within 8 months. Results: Nineteen EM trainees participated. Presimulation, 39% reported never having received training in the medical care of a patient with sexual assault. The proportion of trainees agreeing or strongly agreeing with the statement "I am comfortable and confident managing a case of sexual assault" increased from 21% to 74% following the simulation (p < .05). Discussion: This intervention was associated with EM trainees' increased confidence with and knowledge of medical and forensic evaluations for an adolescent with sexual assault.

Advanced Pediatric Emergency Airway Management: A Multimodality Curriculum Addressing a Rare but Critical Procedure.

Introduction: Advanced airway management in pediatrics is a rare, high stakes skillset. Developing proficiency in these skills is paramount, albeit challenging. Providers require innovative approaches to address initial training and maintenance of procedural competency. To address this, we developed a multimodality curriculum. Methods: Through an interactive problem-based learning session utilizing real intubation videos, hands-on skill stations, and two simulation-based scenarios, participants advanced through educational objectives towards the goal of improving perceived comfort, knowledge, skills, and attitudes in emergency pediatric advanced airway management. Content was developed by integrating varied learning modalities under the learn, see, practice, prove, do, maintain construct. Please note the specialized equipment needed for this curriculum included pediatric airway trainers and a video laryngoscope. Results: We have conducted the curriculum in its entirety four times, reaching 131 interdisciplinary participants. Forty-nine physicians of varying training backgrounds and clinical working environments completed postparticipation evaluations. On a Likert scale ranging from 1 (strongly disagree) to 5 (strongly agree), a significant improvement in perception of comfort with managing the emergent pediatric airway was noted (2.7 to 4.6, p < .0001). Further, 94% of participants reported they strongly agreed (71%) or agreed (23%) that each station added to their perceived knowledge, skills, and attitudes of pediatric airway management. Discussion: After participating in our curriculum, participants self-reported improved comfort in managing the emergent pediatric airway. This curriculum provides educators with resources to navigate the paradigm of obtaining and maintaining competency of a rare but critical skillset.

Geographical affiliation with top 10 NIH-funded academic medical centers and differences between mortality from cardiovascular disease and cancer.

Community engagement and rapid translation of findings for the benefit of patients has been noted as a major criterion for NIH decisions regarding allocation of funds for research priorities. We aimed to examine whether the presence of top NIH-funded institutions resulted in a benefit on the cardiovascular and cancer mortality of their local population. METHODS AND RESULTS: Based on the annual NIH funding of every academic medical from 1995 through 2014, the top 10 funded institutes were identified and the counties where they were located constituted the index group. The comparison group was created by matching each index county to another county which lacks an NIH-funded institute based on sociodemographic characteristics. We compared temporal trends of age-standardized cardiovascular mortality between the index counties and matched counties and states. This analysis was repeated for cancer mortality as a sensitivity analysis. From 1980 through 2014, the annual cardiovascular mortality rates declined in all counties. In the index group, the average decline in cardiovascular mortality rate was 51.5 per 100,000 population (95% CI, 46.8-56.2), compared to 49.7 per 100,000 population (95% CI, 45.9-53.5) in the matched group (P = .27). Trends in cardiovascular mortality of the index counties were similar to the cardiovascular mortality trends of their respective states. Cancer mortality rates declined at higher rates in counties with top NIH-funded medical centers (P < .001). CONCLUSIONS: Cardiovascular mortality rates have decreased with no apparent incremental benefit for communities with top NIH-funded institutions, underscoring the need for an increased focus on implementation science in cardiovascular diseases.

Comparison of Two Telemedicine Delivery Modes for Neonatal Resuscitation Support: A Simulation-Based Randomized Trial.

INTRODUCTION: Previous research has described technical aspects of telemedicine and the clinical impact of provider-to-patient telemedicine; however, little is known about provider-to-provider telemedical interventions. OBJECTIVE: The primary aim of this study was to compare two telemedicine delivery modes on the quality of a simulated neonatal resuscitation. Our secondary aim was to evaluate the providers' task load. METHODS: This was a prospective, single-center, randomized, simulation-based trial comparing a remote neonatal team leader ("teleleader") versus a remote consultant ("teleconsultant"). Participants resuscitated a simulated, apneic, and bradycardic neonate. Performance was assessed by video review and task load was measured by the self-reported NASA task load index (NASA-TLX) tool. In the teleleader group, one remote neonatal specialist assumed the role of team leader in the resuscitation. In the teleconsultant group, the same remote specialist assumed the role of teleconsultant. RESULTS: Twenty-two participants were included in the analyses. The teleleader group was associated with a higher overall checklist score compared to teleconsultants (median score 68%, interquartile range [IQR]: 66-69 vs. 58%, IQR: 42-62; p = 0.016). No significant difference was seen in overall subjective workload as measured by the NASA-TLX tool. However, mental demand and frustration were significantly greater with teleconsultants compared to teleleaders (mean mental demand: 14.1 vs. 17.0 out of 21; frustration: 7.9 vs. 14.7 out of 21). CONCLUSIONS: Simulated neonates randomized to teams with teleleaders received significantly better resuscitative care compared to those randomized to teams with teleconsultants. Mental demand and frustration were higher for providers in the teleconsultant compared to teleleader teams.

Impact of telemedicine on neonatal resuscitation in the emergency department: a simulation-based randomised trial.

Background: The delivery and initial resuscitation of a newborn infant are required but rarely practised skills in emergency medicine. Deliveries in the emergency department are high-risk events and deviations from best practices are associated with poor outcomes. Introduction: Telemedicine can provide emergency medicine providers real-time access to a Neonatal Resuscitation Program (NRP)-trained paediatric specialist. We hypothesised that adherence to NRP guidelines would be higher for participants with access to a remotely located NRP-trained paediatric specialist via telemedicine compared with participants without access. Materials and methods: Prospective single-centre randomised trial. Emergency Medicine residents were randomised into a telemedicine or standard care group. The participants resuscitated a simulated, apnoeic and bradycardic neonate. In the telemedicine group a remote paediatric specialist participated in the resuscitation. Simulations were video recorded and assessed for adherence to guidelines using four critical actions. The secondary outcome of task load was measured through participants' completion of the NASA Task Load Index (NASA-TLX) and reviewers completed a detailed NRP checklist. Results: Twelve participants were included. The use of telemedicine was associated with significantly improved adherence to three of the four critical actions reflecting NRP guidelines as well as a significant improvement in the overall score (p<0.001). On the NASA-TLX, no significant difference was seen in overall subjective workload assessment, but of the subscore components, frustration was statistically significantly greater in the control group (p<0.001). Conclusions: In this study, telemedicine improved adherence to NRP guidelines. Future work is needed to replicate these findings in the clinical environment.

Predicting Hemodynamic Shock from Thermal Images using Machine Learning.

Proactive detection of hemodynamic shock can prevent organ failure and save lives. Thermal imaging is a non-invasive, non-contact modality to capture body surface temperature with the potential to reveal underlying perfusion disturbance in shock. In this study, we automate early detection and prediction of shock using machine learning upon thermal images obtained in a pediatric intensive care unit of a tertiary care hospital. 539 images were recorded out of which 253 had concomitant measurement of continuous intra-arterial blood pressure, the gold standard for shock monitoring. Histogram of oriented gradient features were used for machine learning based region-of-interest segmentation that achieved 96% agreement with a human expert. The segmented center-to-periphery difference along with pulse rate was used in longitudinal prediction of shock at 0, 3, 6 and 12 hours using a generalized linear mixed-effects model. The model achieved a mean area under the receiver operating characteristic curve of 75% at 0 hours (classification), 77% at 3 hours (prediction) and 69% at 12 hours (prediction) respectively. Since hemodynamic shock associated with critical illness and infectious epidemics such as Dengue is often fatal, our model demonstrates an affordable, non-invasive, non-contact and tele-diagnostic decision support system for its reliable detection and prediction.

Simulation-based research to improve infant health outcomes: Using the infant simulator to prevent infant shaking.

Simulation is a technique that creates a situation or environment to allow persons to experience a representation of a real event for the purpose of practice, learning, evaluation, testing, or to gain understanding of systems or human actions. We will first provide an introduction to simulation in healthcare and describe the two types of simulation-based research (SBR) in the pediatric population. We will then provide an overview of the use of SBR to improve health outcomes for infants in health care settings and to improve parent-child interactions using the infant simulator. Finally, we will discuss previous and future research using simulation to reduce morbidity and mortality from abusive head trauma, the most common cause of traumatic death in infancy.

Adherence to Pediatric Cardiac Arrest Guidelines Across a Spectrum of Fifty Emergency Departments: A Prospective, In Situ, Simulation-based Study.

BACKGROUND AND OBJECTIVES: Pediatric out-of-hospital cardiac arrest survival outcomes are dismal (<10%). Care that is provided in adherence to established guidelines has been associated with improved survival. Lower mortality rates have been reported in higher-volume hospitals, teaching hospitals, and trauma centers. The primary objective of this article was to explore the relationship of hospital characteristics, such as annual pediatric patient volume, to adherence to pediatric cardiac arrest guidelines during an in situ simulation. Secondary objectives included comparing adherence to other team, provider, and system factors. METHODS: This prospective, multicenter, observational study evaluated interprofessional teams in their native emergency department (ED) resuscitation bays caring for a simulated 5-year-old child presenting in cardiac arrest. The primary outcome, adherence to the American Heart Association pediatric guidelines, was assessed using a 14-item tool including three component domains: basic life support (BLS), pulseless electrical activity (PEA), and ventricular fibrillation (VF). Provider, team, and hospital-level data were collected as independent data. EDs were evaluated in four pediatric volume groups (low < 1,800/year; medium 1,800-4,999; medium-high 5,000-9,999; high > 10,000). Cardiac arrest adherence and domains were evaluated by pediatric patient volume and other team and hospital-level characteristics, and path analyses were performed to evaluate the contribution of patient volume, systems readiness, and teamwork on BLS, PEA, and VF adherence. RESULTS: A total of 101 teams from a spectrum of 50 EDs participated including nine low pediatric volume (<1,800/year), 36 medium volume (1,800-4,999/year), 24 medium-high (5,000-9,999/year), and 32 high volume (≥10000/year). The median total adherence score was 57.1 (interquartile range = 50.0-78.6). This was not significantly different across the four volume groups. The highest level of adherence for BLS and PEA domains was noted in the medium-high-volume sites, while no difference was noted for the VF domain. The lowest level of BLS adherence was noted in the lowest-volume EDs. Improved adherence was not directly associated with higher pediatric readiness survey (PRS) score provider experience, simulation teamwork performance, or more providers with Pediatric Advanced Life Support (PALS) training. EDs in teaching hospitals with a trauma center designation that served only children demonstrated higher adherence compared to nonteaching hospitals (64.3 vs 57.1), nontrauma centers (64.3 vs. 57.1), and mixed pediatric and adult departments (67.9 vs. 57.1), respectively. The overall effect sizes for total cardiac adherence score are ED type γ = 0.47 and pediatric volume (low and medium vs. medium-high and high) γ = 0.41. A series of path analyses models was conducted that indicated that overall pediatric ED volume predicted significantly better guideline adherence, but the effect of volume on performance was only mediated by the PRS for the VF domain. CONCLUSIONS: This study demonstrated variable adherence to pediatric cardiac arrest guidelines across a spectrum of EDs. Overall adherence was not associated with ED pediatric volume. Medium-high-volume EDs demonstrated the highest levels of adherence for BLS and PEA. Lower-volume EDs were noted to have lower adherence to BLS guidelines. Improved adherence was not directly associated with higher PRS score provider experience, simulation teamwork performance, or more providers with PALS training. This study demonstrates that current approaches optimizing the care of children in cardiac arrest in the ED (provider training, teamwork training, environmental preparation) are insufficient.

Providers' Perceptions of Caring for Pediatric Patients in Community Hospital Emergency Departments: A Mixed-methods Analysis.

BACKGROUND: Approximately 90% of pediatric emergency care is provided in community emergency departments (CEDs) that care for both adults and children. Paradoxically, the majority of pediatric emergency medicine knowledge generation, quality improvement work, and clinical training occurs in children's hospitals. There is a paucity of information of perceptions on pediatric care from CED providers. This information is needed to guide the development of strategies to improve CED pediatric readiness. OBJECTIVE: The objective was to explore interprofessional CED providers' perceptions of caring for pediatric patients. METHODS: A preparticipation survey collected data on demographics, experience, and comfort in caring for children. Emergency pediatric simulations were then utilized to prime interprofessional teams for debriefings. These discussions underwent qualitative analysis by three blinded authors who coded transcripts into themes through an inductive method derived from grounded theory. The other authors participated in confirmability and dependability checks. RESULTS: A total of 171 community hospital providers from six CEDs completed surveys (49% nurses, 22% physicians, 23% technicians). The majority were PALS trained (70%) and experienced fewer than five pediatric resuscitations in their careers (61%). Most self-reported comfort in caring for acutely ill and injured children. From the debriefings, three major challenge themes emerged: 1) knowledge and skill limitations attributed to infrequency of training and actual clinical events, 2) the emotional toll of caring for a sick child, and 3) acknowledgment of pediatric specific quality and safety deficits. Subthemes focused on causes and potential mitigating factors contributing to these challenges. A solution theme highlighted novel partnering opportunities with local children's hospitals. CONCLUSION: Interprofessional CED providers perceive that caring for pediatric patients is challenging due to case infrequency, the emotional toll of caring for sick children, and pediatric quality and safety deficits in their systems. These areas of focus can be used to generate specific strategies for improving CED pediatric readiness.
