Extreme thrombocytosis predicts Kawasaki disease in infants.

Infants with Kawasaki disease are at high risk of developing life-threatening coronary complications, yet may elude timely diagnosis because they often lack the full complement of classic clinical features. We retrospectively studied 26,540 children 1 year of age or less who were evaluated at a tertiary care pediatric emergency department in whom a platelet count was performed. Among those infants with fever without a source identified, 8.5% with platelet counts of 800,000 cells/mm(3) or greater had Kawasaki disease compared to 0.4% with platelet counts of less than 800,000 cells/mm(3) (likelihood ratio for Kawasaki disease was 17 [95% confidence interval, 8-34]). Because many infants present atypically, Kawasaki disease should be considered in all children of 1 year or less with prolonged fever, extreme elevation of the platelet count, and no compelling alternative diagnosis.

Pediatric hospitalists: report of a leadership conference.

OBJECTIVES: To summarize a meeting of academic pediatric hospitalists and to describe the current state of the field. METHODS: The Ambulatory Pediatric Association sponsored a meeting for academic pediatric hospitalists in November 2003. The purpose of the meeting was to discuss and to define roles of academic pediatric hospitalists, including their roles as clinicians, educators, and researchers, and to discuss organizational issues and unique hospitalist issues within general academic pediatrics. Workshops were held in the areas of organization and administration, academic life, research, and education. A literature review was also conducted in the areas discussed. RESULTS: More than 130 physicians attended. Thirteen workshops were held, and all information was summarized in large-group sessions for all attendees. CONCLUSIONS: Pediatric hospital medicine is a rapidly growing field, with an estimated 800 to 1000 pediatric hospitalists currently practicing. Initial work has defined the clinical environment and has begun to stake out a unique knowledge and skill set. The Pediatric Hospitalists in Academic Settings conference demonstrated the audience for additional development and the resources to move forward.

Variations in management of common inpatient pediatric illnesses: hospitalists and community pediatricians.

OBJECTIVE: The goal was to test the hypothesis that pediatric hospitalists use evidence-based therapies and tests more consistently in the care of inpatients and use therapies and tests of unproven benefit less often, compared with community pediatricians. METHODS: A national survey was administered to hospitalists and a random sample of community pediatricians. Hospitalists and community pediatricians reported their frequency of use of diagnostic tests and therapies, on 5-point Likert scales (ranging from never to almost always), for common inpatient pediatric illnesses. Responses were compared in univariate and multivariable logistic regression analyses controlling for gender, race, years out of residency, days spent attending per year, hospital practice type, and completion of fellowship/postgraduate training. RESULTS: Two hundred thirteen pediatric hospitalists and 352 community pediatricians responded. In multivariable regression analyses, hospitalists were significantly more likely to report often or almost always using the following evidence-based therapies for asthma: albuterol and ipratropium in the first 24 hours of hospitalization. After the first urinary tract infection, hospitalists were more likely to report obtaining the recommended renal ultrasound and voiding cystourethrogram. Hospitalists were significantly more likely than community pediatricians to report rarely or never using the following therapies of unproven benefit: levalbuterol, inhaled steroid therapy, and oral steroid therapy for bronchiolitis; stool culture and rotavirus testing for gastroenteritis; and ipratropium after 24 hours of hospitalization for asthma. CONCLUSION: Overall, in comparison with community pediatricians, hospitalists reported greater adherence to evidence-based therapies and tests in the care of hospitalized patients and less use of therapies and tests of unproven benefit.

Preventable adverse events in infants hospitalized with bronchiolitis.

OBJECTIVE: To determine the incidence of preventable adverse events (AEs) and near misses (NMs) among infants hospitalized for bronchiolitis at a pediatric tertiary care hospital and the impact of these errors on hospital length of stay (LOS). METHODS: We studied 143 infants with bronchiolitis, ages 0 to 12 months, admitted from December 2002 to April 2003. Using prospective chart review and staff reports, we captured medical errors and AEs. Each event was classified as a (1) preventable AE, (2) nonpreventable AE, (3) intercepted NM, (4) nonintercepted NM, or (5) error with little or no potential for harm. RESULTS: Of 143 patients, 15 (10%) suffered an AE or NM. The incidence of preventable AEs was 10 per 100 admissions. We found a higher incidence of preventable AEs and NMs among critically ill patients (CIPs) compared with non-CIPs (68 vs 5 per 100 admissions, respectively), making the absolute risk of an AE or NM 14 times more likely in CIPs. Mean LOS was significantly longer for CIPs with at least 1 AE (9.1 +/- 8.8 days) than for CIPs without AEs (2.9 +/- 1.5 days). Mean LOS was not significantly different between non-CIPs who did (3.8 +/- 2.6 days) and did not (4.2 +/- 5.0 days) experience an AE. CONCLUSIONS: Preventable AEs occur frequently among patients admitted for bronchiolitis, especially those who are critically ill. CIPs who suffer AEs during their hospitalization have longer hospital LOSs. Future studies should investigate error-prevention strategies with a focus on those patients with severe disease.

Effect of a pediatric hospitalist system on housestaff education and experience.

OBJECTIVE: To determine the effect of a pediatric hospitalist system on housestaff education and experience. SETTING: Free-standing academic children's hospital. Hospitalists were introduced in June 24, 1998, to supervise teaching and care on the general pediatric wards. METHODS: On 2 surveys, housestaff rated their skills, knowledge, and experiences on the wards (experiences survey), and the quality of teaching and supervision by attending physicians (attending survey). Responses before and after the introduction of the hospitalist system were compared using Wilcoxon nonparametric tests. RESULTS: Seventy-six (70%) of the 109 interns and 54 (62%) of the 87 senior residents responded to the experiences survey. Following introduction of the hospitalist system, the interns' mean overall rating of the general pediatrics wards rose from 4.1 to 4.7 on a 5-point Likert scale (P =.01). Their ratings of comparison rotations did not change significantly. Interns' satisfaction with the educational experience (3.2 to 3.5 of a 4-point Likert scale, P<.05), supervision, and quality of life on the pediatrics wards also improved significantly, as did their self-assessments of skills and knowledge related to general pediatrics training. Senior residents' ratings were generally unchanged. Three hundred seventy-one (63%) of the 593 attending physicians' surveys were completed. Compared with nonhospitalist attendings, hospitalists were rated more effective role models (4.7 vs 4.5 points, P<.05) and teachers (4.7 vs 4.4 points, P<.01). They were rated more knowledgeable (4.8 vs 4.5 of 5, P<.001) and accessible (4.7 vs 4.5 points, P<.05), involved housestaff more in the learning process (4.7 vs 4.4 points, P<.05), and gave better feedback (4.5 vs 4.2 points, P<.01). Hospitalists' bedside teaching, however, was rated lower (3.7 vs 4.2 points, P<.001). CONCLUSIONS: Overall, hospitalists were rated significantly higher as educators than were traditional attending physicians. Introduction of a hospitalist system was associated with improved intern experience and quality of life on general pediatrics wards, and with improved self-reported skills and knowledge in general pediatrics.
