Bringing PERT to Pediatrics: Initial Experience and Outcomes of a Pediatric Multidisciplinary Pulmonary Embolism Response Team (PERT).

INTRODUCTION: Multidisciplinary Pulmonary Embolism Response Teams (PERTs) streamline care of adults with life-threatening pulmonary embolism (PE). Given rarity of pediatric PE, developing a clinical, educational, and research PERT paradigm is a novel and underutilized concept in pediatrics. RESEARCH QUESTION: Is PERT feasible in pediatrics, and does it improve PE care? STUDY DESIGN AND METHODS: A strategy-to-execution proposal to launch a pediatric PERT was developed for institutional buy-in. Key stakeholders collectively implemented PERT. Data were collected for the two-year pre- and post-PERT eras, and outcomes were compared. RESULTS: PERT implementation took 12 months. Our PERT, led by hematology, comprises of pediatric experts in emergency medicine, critical care, interventional cardiology, anesthesiology, and interventional radiology. Data on 30 patients pre-PERT and 31 post-PERT were analyzed. Pre-PERT, 10%(3/30), 13%(4/30), 20%(6/30), and 57%(17/30), and post-PERT, 3%(1/31), 10%(3/31), 16%(5/31), and 71%(22/31) were categorized as high-risk, intermediate-LOW risk, intermediate-HIGH risk, and low-risk PE, respectively. Post-PERT, there were 13 unique PERT activations. PERT was activated on all eligible PE patients and, additionally, on four low-risk PEs. Time-to-echocardiogram was shorter post-PERT (4.7 hrs vs 2 hrs, P=0.0147). Anticoagulation was ordered (90 min vs 54 min, P=0.003) and given sooner (154 min vs 113 min, P=0.049) post-PERT. There were no differences in time-to-reperfusion therapies (12 hrs pre-PERT vs 8.7 hrs post-PERT, P=0.1). Five (83.3%) of six eligible (intermediate-HIGH and high-risk) patients received reperfusion therapies in the post-PERT era compared to three (37.5%) of eight eligible patients in the pre-PERT era (P=0.0001). There were no differences in major bleeding, mortality, or length of stay in either era. INTERPRETATION: The pediatric PERT paradigm was successfully created and adopted locally. Our PERT enhanced access to experts, facilitated timely advanced therapies, and held value for low-risk PE. The University of Texas Southwestern Medical Center (UTSW) and Children's Health System of Texas pediatric PERT may serve as a best-practice model for streamlining care for pediatric PE.

Emergency Medical Response for Non-Hospitalized Person Events in a Children's Hospital.

OBJECTIVES: Hospital-based code blue (CB) teams are designed for hospitalized patients (HP) with unanticipated medical emergencies outside of an ICU. At our freestanding pediatric institution, the same team responds to CB calls involving nonhospitalized persons (NHP) throughout the hospital campus. We hypothesized there are significant differences between the characteristics of NHP and HP requiring emergency medical response, and most responses for NHP do not require advanced critical care. METHODS: We analyzed a retrospective cohort of CB responses at our large, urban, academic children's medical center from January to December 2017. We evaluated the demographic and clinical characteristics of these HP compared with NHP events. RESULTS: There were 168 CB activations during the study, of which 135 (80.4%) were for NHP. Ninety-one (67.4%) of the NHP responses involved adults (age >18 years) compared with 6 (18.2%) of the HP. Triggers for CB team activation for NHP were most frequently syncope (42.2%), seizure (10.3%), or fall (9.6%) compared with seizure (30.3%), hypoxia (27.3%), or anaphylaxis (12.1%) for HP. Critical interventions such as bag-mask ventilation and cardiopulmonary resuscitation were infrequently performed for either cohort. CONCLUSIONS: CB activations in our pediatric institution more often involve NHP than HP. NHP responses are more likely to involve adults and infrequently require advanced interventions. Use of a pediatric CB team for NHP events may be an unnecessary use of pediatric critical care resources. Future studies are warranted to evaluate the most effective team composition, training, and response system for NHP in a freestanding children's hospital.

HeartWatch: Implementing a Pediatric Heart Center Program to Prevent Cardiac Arrests Outside the ICU.

Pediatric patients with cardiovascular disease are at increased risk of cardiopulmonary arrest. Despite utilization of Cardiac Pediatric Early Warning Scores to identify patients at risk of decompensation, our institution had a twofold increase in cardiac arrests (CAs) in the acute care cardiology unit (ACCU) over 2 years. Through a quality improvement initiative, we developed a watcher program, HeartWatch, to reduce the CA arrest rate in the ACCU by 50% over the first year of implementation. Methods: HeartWatch aims to identify patients not adequately captured by Cardiac Pediatric Early Warning Scores who are at high risk for sudden decompensation. Inclusion criteria were developed and evaluated during pilot and implemented phases (April 2020-April 2021) and then monitored in a sustained phase through June 2022. Our primary outcome was the reduction in the out-of-ICU CA rate. Results: During the 13 months, we enrolled 169 patients, and the CA rate decreased from 0.7 to 0.33 per 1,000 patient days, a 53% reduction. The CA rate further decreased to 0.28 events per 1,000 patient days, a 60% reduction, by June 2022. The most common indications for HeartWatch inclusion were high-risk single-ventricle patients (31%) and patients with diminished ventricular function (20%). Conclusions: Implementation of HeartWatch was associated with a meaningful reduction in CA in the ACCU. Creating shared mental models for high-risk patients is essential for patient safety. Future work will optimize local processes that focus on the sustainability of our gains. We will also evaluate opportunities to adapt and implement a similar framework in other institutions to assess reproducibility.

Publication outcomes of abstracts presented at an American College of Rheumatology/Association of Rheumatology Health Professionals annual scientific meeting.

OBJECTIVE: The American College of Rheumatology (ACR) and the Association of Rheumatology Health Professionals (ARHP) Annual Scientific Meeting is an important forum for early dissemination of novel ideas. However, unlike published studies in peer-reviewed journals, reviewers select abstracts based solely on a general summary of the research. Analyses of the scientific impact and the publication record of the ACR/ARHP Annual Meeting have not been previously described. This study characterizes publication trends and outcomes associated with abstracts presented at the ACR/ARHP Annual Scientific Meeting. METHODS: We identified all abstracts accepted for oral or poster presentation at the 2006 ACR/ARHP Annual Scientific Meeting. Using a defined search algorithm, we conducted a manual PubMed search for each accepted abstract, which was repeated by a custom computerized search, and analyzed the resulting journal title, impact factor, and time to publication. RESULTS: A total of 2,149 abstracts were analyzed. The overall publication ratio was 59.1%. The mean ± SD time from abstract presentation to publication was 18.2 ± 15.2 months with a mean ± SD impact factor of 5.61 ± 4.20. Overall, studies presented in oral format were significantly more likely to be published than poster presentations (P < 0.0001). The average time to publication was significantly shorter for basic science studies than clinical research studies (P < 0.0001). The average journal impact factor of published studies presented in oral format was significantly higher than those presented as posters (P < 0.0001). CONCLUSION: These results reflect high research productivity with a publication ratio of approximately 60% for abstracts presented at the 2006 Annual Scientific Meeting.
