Comparisons between Full-time and Part-time Pediatric Emergency Physicians in Pediatric Emergency Department.

BACKGROUND: Pediatric emergency medicine is a young field that has established itself in recent decades. Many unanswered questions remain regarding how to deliver better pediatric emergency care. The implementation of full-time pediatric emergency physicians is a quality improvement strategy for child care in Taiwan. The aim of this study is to evaluate the quality of care under different physician coverage models in the pediatric emergency department (ED). METHODS: The medical records of 132,398 patients visiting the pediatric ED of a tertiary care university hospital during January 2004 to December 2006 were retrospectively reviewed. Full-time pediatric emergency physicians are the group specializing in the pediatric emergency medicine, and they only work in the pediatric ED. Part-time pediatricians specializing in other subspecialties also can work an extra shift in the pediatric ED, with the majority working in their inpatient and outpatient services. We compared quality performance indicators, including: mortality rate, the 72-hour return visit rate, length of stay, admission rate, and the rate of being kept for observation between full-time and part-time pediatric emergency physicians. RESULTS: An average of 3678 ± 125 [mean ± standard error (SE)] visits per month (with a range of 2487-6646) were observed. The trends in quality of care, observed monthly, indicated that the 72-hour return rate was 2-6% and length of stay in the ED decreased from 11.5 hours to 3.2 hours over the study period. The annual mortality rate within 48 hours of admission to the ED increased from 0.04% to 0.05% and then decreased to 0.02%, and the overall mortality rate dropped from 0.13% to 0.07%. Multivariate analyses indicated that there was no change in the 72-hour return visit rate for full-time pediatric emergency physicians; they were more likely to admit and keep patients for observation [odds ratio = 1.43 and odds ratio = 1.71, respectively], and these results were similar to those of senior physicians. CONCLUSION: Full-time pediatric emergency physicians in the pediatric ED decreased the mortality rate and length of stay in the ED, but had no change in the 72-hour return visit rate. This pilot study shows that the quality of care in pediatric ED after the implementation of full-time pediatric emergency physicians needs further evaluation.

High prevalence and antimicrobial resistance of urinary tract infection isolates in febrile young children without localizing signs in Taiwan.

BACKGROUND: Antimicrobial susceptibility and prevalence of pediatric urinary tract infection (UTI) is very useful for pediatricians in selecting effective antibiotics in time to improve outcomes in patients. This study aimed to determine the prevalence rate, bacterial distribution, and antimicrobial susceptibility of UTI in febrile young children at a teaching hospital in northern Taiwan. METHODS: From January 2011 to December 2011, all urinary isolates from suspected cases of UTI in febrile young children aged from 1 day to 36 months visiting the Pediatric Emergency Room of Chang Gung Children's Hospital, Taoyuan, Taiwan were identified by conventional methods. Antibiotic susceptibility was determined according to the Clinical and Laboratory Standards Institute. RESULTS: A total of 5470 (78%) from 7009 eligible children were enrolled in the study, and 619 (11.3%) had a diagnosis of UTI. The most prevalent bacterium was Escherichia coli (68%) followed by Klebsiella pneumoniae (8.1%) and Proteus mirabilis (6.8%). Ampicillin, piperacillin, and trimethoprim-sulfamethoxazole (TMP-SMX) showed a higher resistance rate in the three predominant bacteria. All tested bacteria showed higher resistance to ampicillin (79.3%) and TMP-SMX (44.1%), and lower resistance to cefazolin (17.7%) and gentamicin (13.0%). Fourteen percent of the isolates produced extended spectrum ß-lactamase (ESBL), among which 93.33% were E. coli isolates. CONCLUSION: The overall prevalence of UTI in this study was higher than previously reported in febrile children. Higher antimicrobial resistance was found in ampicillin and TMP-SMX. Among commonly used antibiotics, cefazolin and gentamicin are recommended to treat UTI in febrile children aged < 3 years without localizing signs.

Invasive pediatric Neisseria meningitidis infections.

BACKGROUND AND PURPOSE: Neisseria meningitidis usually causes severe infection in children, but occurs only sporadically in Taiwan. However, the number of infections increased in 2001 and 2002. This study was performed to ascertain the epidemiology and clinical manifestations of infections caused by meningococcus in a pediatric population. METHODS: The medical charts of patients with meningococcal diseases who were admitted to Chang Gung Children's Hospital, Taoyuan, Taiwan, from July 1998 to December 2005 were retrospectively reviewed. Data were analyzed for age distribution, serogroups, clinical diagnoses, treatment, acute complications, and outcomes. RESULTS: Sixteen children with meningococcal disease were identified. Their ages ranged from 1 month to 15 years (average, 3 years). Most patients (62.5%) were younger than 1 year and the second most frequent age group was 6 to 15 years (18.75%). There were 56.25% boys and 43.75% girls. The identified serogroups were B (43.75%), W135 (31.25%), A (6.25%), Y (6.25%), and undetermined (12.5%). The antibiotics used in this study were ampicillin, ceftriaxone, cefotaxime, and aqueous penicillin; the mean total treatment duration was 10 days. Purpura fulminans (37.5%), disseminated intravascular coagulopathy (31.25%), respiratory failure (25.0%), and shock (25.0%) were the commonest acute complications. Most (87.5%) of the patients survived. One patient had long-term sequelae of hearing impairment and speech delay. The mortality rate was 12.5%. CONCLUSIONS: Serogroup B and W-135 were 2 predominant serogroups to cause pediatric meningococcus, and the majority of infections occurred in children younger than 1 year. Continuous surveillance and prevention of meningococcal infections are of great importance.
