Association of Models of Care for Kawasaki Disease With Utilization and Cardiac Outcomes.

OBJECTIVES: Describe the prevalence of different care models for children with Kawasaki disease (KD) and evaluate utilization and cardiac outcomes by care model. METHODS: Multicenter, retrospective cohort study of children aged 0 to 18 hospitalized with KD in US children's hospitals from 2017 to 2018. We classified hospital model of care via survey: hospitalist primary service with as-needed consultation (Model 1), hospitalist primary service with automatic consultation (Model 2), or subspecialist primary service (Model 3). Additional data sources included administrative data from the Pediatric Health Information System database supplemented by a 6-site chart review. Utilization outcomes included laboratory, medication and imaging usage, length of stay, and readmission rates. We measured the frequency of coronary artery aneurysms (CAAs) in the full cohort and new CAAs within 12 weeks in the 6-site chart review subset. RESULTS: We included 2080 children from 44 children's hospitals; 21 hospitals (48%) identified as Model 1, 19 (43%) as Model 2, and 4 (9%) as Model 3. Model 1 institutions obtained more laboratory tests and had lower overall costs (P < .001), whereas echocardiogram (P < .001) and immune modulator use (P < .001) were more frequent in Model 3. Secondary outcomes, including length of stay, readmission rates, emergency department revisits, CAA frequency, receipt of anticoagulation, and postdischarge CAA development, did not differ among models. CONCLUSIONS: Modest cost and utilization differences exist among different models of care for KD without significant differences in outcomes. Further research is needed to investigate primary service and consultation practices for KD to optimize health care value and outcomes.

Comparison of a Teaching and Nonteaching Service at a Children's Hospital in the Community.

OBJECTIVE: The impact of trainees on inpatient patient care is incompletely understood. This study sought to discern the impact of trainees on patient outcomes and costs at a children's hospital in the community. We hypothesized that there would be no differences in patient outcomes and costs on an inpatient teaching service compared to a nonteaching service. As a secondary goal, we analyzed trainee evaluations. METHODS: The authors conducted a cohort study of patients hospitalized from October 1, 2016 to September 30, 2017 on an acute care unit in a children's hospital in the community. Using t test or Fisher exact test, the authors compared patient outcomes between teaching and nonteaching services including, length of stay, discharge times, readmission rates, rapid response team (RRT) calls, pediatric intensive care unit (PICU) transfers, hospital transfers, and costs. RESULTS: During the study period, there were 1066 patients admitted and discharged from the teaching service and 1038 from the nonteaching service. There were no statistically significant differences in patient demographics or patient complexity. Similarly, there were no differences in length of stay, discharge times, readmission rates, RRT calls, PICU transfers, hospital transfers or patient costs between services. Trainee evaluations of the inpatient experience were overwhelmingly positive. CONCLUSIONS: In a children's hospital in the community, there were no significant differences in patient outcomes and costs on a teaching service compared to a nonteaching service. Furthermore, trainee evaluations suggested a favorable learning experience, illustrating the feasibility of incorporating trainees into inpatient care in a nontraditional learner setting.

Kawasaki Disease and Multisystem Inflammatory Syndrome in Children: An Overview and Comparison.

Kawasaki disease (KD) and multisystem inflammatory syndrome in children (MIS-C) are inflammatory conditions that present diagnostic and therapeutic challenges to the physician. Although many of their features overlap, they are two distinct conditions. KD is a febrile illness most commonly affecting children younger than five years. It manifests with prolonged fever and at least four of the following features: bilateral bulbar conjunctivitis, mucositis, diffuse maculopapular rash, extremity changes, and cervical lymphadenopathy of 1.5 cm or more in diameter. Patients with MIS-C may have many of the same manifestations but tend to have higher rates of gastrointestinal and neurocognitive symptoms and signs of shock on presentation. Both conditions are associated with cardiac sequelae, including coronary artery aneurysms, although children with MIS-C are at high risk of developing ventricular dysfunction and depressed cardiac output. Lymphocytopenia, thrombocytopenia, elevated troponin, and elevated B-type natriuretic peptide are key laboratory findings of MIS-C that can help distinguish it from KD. The use of intravenous immune globulin is well established in KD and also appears to have a role in the treatment of MIS-C. Aspirin has been used in KD for an anti-inflammatory effect, and low-dose aspirin is recommended for MIS-C to reduce the risk of thrombosis. In addition to supportive care, patients with MIS-C may benefit from immunomodulatory medications, although data on this topic are evolving.

Variability in Kawasaki Disease Practice Patterns: A Survey of Hospitalists at Pediatric Hospital Medicine 2017.

OBJECTIVE: To explore practice variations in the care of patients with Kawasaki disease (KD) among pediatric hospitalist physicians (PHPs). METHODS: A 13-item questionnaire was developed by a multi-institutional group of KD experts. The survey was administered via live-audience polling by using smartphone technology during a KD plenary session at the 2017 Pediatric Hospital Medicine National Meeting, and simple descriptive statistics were calculated. RESULTS: Of the 297 session attendees, 90% responded to at least 1 survey question. Approximately three-quarters of respondents identified as PHPs practicing in the United States. The reported length of inpatient monitoring after initial intravenous immunoglobulin (IVIG) therapy demonstrated a wide time distribution (30% 24 hours, 36% 36 hours, and 31% 48 hours). Similarly, PHP identification of the treatment failure interval, indicated by recrudescent fever after IVIG, demonstrated a broad distribution (56% 24 hours, 27% 36 hours, and 16% 48 hours). Furthermore, there was variation in routine consultation with non-PHP subspecialists. In contrast, PHPs reported little variation in their choice of initial and refractory treatment of patients with KD. CONCLUSIONS: In a convenience sample at a national hospitalist meeting, there was variation in reported KD practice patterns, including observation time after initial treatment, time when the recurrence of fever after initial therapy was indicative of nonresponse to IVIG, and routine consultation of non-PHP subspecialists. These results may guide future study of KD practice patterns and inform efforts to improve evidence-based practices in the care of patients with KD.

Management of Complicated Pneumonia in Childhood: A Review of Recent Literature.

BACKGROUND: Despite declining rates of community acquired pneumonia (CAP) in children, complicated pneumonia has been on the rise in the last two decades. The management of complicated pneumonia is challenging and continues to be an area of investigation. Despite recently published guidelines, many gaps exist and recent studies attempt to answer challenging questions. OBJECTIVE: The aim was to review recently published literature to inform the clinician about the most up to date management of complicated pneumonia in children. METHODS: Using Medline, a search of the medical literature was conducted in order to find relevant clinical trials and review articles published in the last 5 years. RESULTS: Narrow spectrum antibiotics including ampicillin and azithromycin remain important first line agents, but directed therapy towards causative pathogens is the ideal standard practice. Novel DNA isolation technologies hold promise for raising the diagnostic yield of pleural fluid. Surgical interventions are often required and new literature further supports the use of fibrinolytics and minimally invasive chest tube thoracostomy. Not to be overlooked is the importance of supportive measures including oxygen therapy and adequate fluid, electrolyte and nutrition support. The use of other adjunctive therapies such as steroids in pediatric complicated pneumonia remains controversial. CONCLUSION: Recent studies have shown promise in establishing best practices for evaluation and management of complicated pneumonia in children. Despite these robust efforts however, many areas are in need of future inquiry and prospective studies could help to better understand the optimal therapeutic and diagnostic options for children with this common and persistent childhood illness.

A 3-Week-Old With an Isolated "Blueberry Muffin" Rash.

A 3-week-old boy, former 39-week term infant, presented to the emergency department with a rash. One week before presentation, he developed dark, purple papules on his forehead, which then spread to the abdomen and inguinal regions. Throughout this time, he was eating well, gaining weight, developing appropriately, and was afebrile without cough, congestion, or rhinorrhea. On presentation, the patient was well appearing with normal vital signs. His weight was 4.83 kg (86th percentile for age), his length was 56 cm (47th percentile for age), and his head circumference was 37 cm (62nd percentile for age). On skin examination, there were scattered purpuric papules and macules on the scalp, forehead, trunk, abdomen, and inguinal region. Initial laboratory studies were remarkable only for mild anemia. Our expert panel examines the case, offers a differential for a child with a "blueberry muffin" rash, and makes diagnostic considerations.

A theory-informed, process-oriented Resident Scholarship Program.

BACKGROUND: The Accreditation Council for Graduate Medical Education requires residency programs to provide curricula for residents to engage in scholarly activities but does not specify particular guidelines for instruction. We propose a Resident Scholarship Program that is framed by the self-determination theory (SDT) and emphasize the process of scholarly activity versus a scholarly product. METHODS: The authors report on their longitudinal Resident Scholarship Program, which aimed to support psychological needs central to SDT: autonomy, competence, and relatedness. By addressing those needs in program aims and program components, the program may foster residents' intrinsic motivation to learn and to engage in scholarly activity. To this end, residents' engagement in scholarly processes, and changes in perceived autonomy, competence, and relatedness were assessed. RESULTS: Residents engaged in a range of scholarly projects and expressed positive regard for the program. Compared to before residency, residents felt more confident in the process of scholarly activity, as determined by changes in increased perceived autonomy, competence, and relatedness. Scholarly products were accomplished in return for a focus on scholarly process. CONCLUSIONS: Based on our experience, and in line with the SDT, supporting residents' autonomy, competence, and relatedness through a process-oriented scholarship program may foster the curiosity, inquisitiveness, and internal motivation to learn that drives scholarly activity and ultimately the production of scholarly products.

A Case of an 11-year-old With Cough, Diarrhea, and Findings of Concern in His Lungs and Spleen.

This is the case of a previously healthy, 11-year-old male of Indian descent who presented to the emergency department with a 2-month history of nausea, vomiting, diarrhea, fatigue, cough, and 7-lb weight loss. Acutely, he developed 5 days of fever as high as 39.4°C. He had a remote travel history to the Middle East. On physical examination, he was febrile and tachycardic, was thin but otherwise had a normal examination. His inflammatory markers were elevated: erythrocyte sedimentation rate was 93 mm/hour and his C-reactive protein was 25.4 mg/L. A complete blood count revealed a white blood cell count of 17,000 × 10(3)/µL with increased bands. His hemoglobin level was 8.8 g/dL with a mean corpuscular volume of 81 fl. Platelets were 556 × 10(3)/µL. A chest radiograph was concerning for a cavitary lung lesion and an abdominal ultrasound revealed multiple hypoechoic lesions in his spleen. Our panel of experts reviews his case and examines the workup of this patient with diverse symptoms and focal findings on chest radiograph and abdominal ultrasound.

A 2-year-old with 4 weeks of daily fever.

A 2-year-old female presents for evaluation of 4 weeks of daily fevers. When the fevers began, she had mild upper respiratory tract symptoms, which quickly resolved. The fevers persisted, however, with a maximum of 40°C. The child's review of symptoms was significant for a 1-kg weight loss over the past month. Ten months before presentation, she had moved from Saudi Arabia with her family. One week before the onset of symptoms, she had visited a petting zoo. During episodes of fever, the patient was ill-appearing and had an elevated heart rate and respiratory rate. On examination, she was found to be thin, febrile, tachycardic, and with scattered lymphadenopathy. Results of laboratory tests were remarkable for an elevated white blood cell count of 16,100 cells per uL with a neutrophilic predominance. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were elevated at 99 mm/h and 27 mg/dL, respectively. A chest radiograph indicated a small amount of fluid in the interlobar fissures. Our expert panel examines her case, offers a definition of fever of unknown origin, and makes diagnostic considerations.
