摘要:
Objective.To evaluate the effects of the introduction of an alcohol-based hand gel and multifaceted quality improvement (QI) interventions on hand hygiene (HH) compliance.Design.Interventional, randomized cohort study with four study phases (baseline; limited intervention in two units; full intervention in three units; washout phase), performed in three intensive care units at a pediatric referral hospital.Methods.During 724 thirty-minute daytime monitoring sessions, a nonidentified observer witnessed 12 216 opportunities for HH and recorded compliance.Interventions.Introduction of an alcohol-based hand gel; multifaceted QI interventions (educational program, opinion leaders, performance feedback).Results.Baseline compliance decreased after the first 2 weeks of observation from 42.5% to 28.2% (presumably because of waning of a Hawthorne effect), further decreased to 23.3% in the limited intervention phase and increased to 35.1% after the introduction of a hand gel with QI support in all three units (P< 0.001). The rise in compliance persisted in the last phase (compliance, 37.2%); however, a gradual decline was observed during the final weeks. Except for the limited intervention phase, compliance achieved through standard handwashing and glove use remained stable around 20 and 10%, respectively, whereas compliance achieved through gel use increased to 8% (P< 0.001). After adjusting for confounding, implementation of the hand gel with QI support remained significantly associated with compliance (odds ratio, 1.6; 95% confidence interval, 1.4 to 1.8). In a final survey completed by 62 staff members, satisfaction with the hand gel was modest (45%).Conclusions.We noted a statistically significant, modest improvement in compliance after introduction of an alcohol-based hand gel with multifaceted QI support. When appropriately implemented, alcohol-based HH may be effective in improving compliance.

摘要:
Background.A few previous studies have suggested that childhood vaccines, particularly whole cell pertussis vaccine, may increase the risk of asthma. We evaluated the suggested association between childhood vaccinations and risk of asthma.Methods.Cohort study involving 167 240 children who were enrolled in 4 large health maintenance organizations during 1991 to 1997, with follow-up from birth until at least 18 months to a maximum of 6 years of age. Vaccinations were ascertained through computerized immunization tracking systems, and onset of asthma was identified through computerized data on medical care encounters and medication dispensings.Results.In the study 18 407 children (11.0%) developed asthma, with a median age at onset of 11 months. The relative risks (95% confidence intervals) of asthma were: 0.92 (0.83 to 1.02) for diphtheria, tetanus and whole cell pertussis vaccine; 1.09 (0.9 to 1.23) for oral polio vaccine; 0.97 (0.91 to 1.04) for measles, mumps and rubella (MMR) vaccine; 1.18 (1.02 to 1.36) forHaemophilus influenzaetype b (Hib); and 1.20 (1.13 to 1.27) for hepatitis B vaccine. The Hib result was not consistent across health maintenance organizations. In a subanalysis restricted to children who had at least 2 medical care encounters during their first year, the relative risks decreased to 1.07 (0.71 to 1.60) for Hib and 1.09 (0.88 to 1.34) for hepatitis B vaccine.Conclusion.There is no association between diphtheria, tetanus and whole cell pertussis vaccine, oral polio vaccine or measles, mumps and rubella vaccine and the risk of asthma. The weak associations for Hib and hepatitis B vaccines seem to be at least partially accounted for by health care utilization or information bias.

摘要:
Background.The objective of this study was to examine central venous catheter (CVC)-related nosocomial blood stream infection risks of umbilical venous, percutaneous and Broviac catheters, as well as variations in CVC use and CVC-related risk for nosocomial blood stream infection in the neonatal intensive care unit (NICU).Methods.A cohort study was performed based on 19 507 infants admitted to 17 NICUs in the Canadian Neonatal Network from January, 1996, through October, 1997. Information on these subjects was prospectively collected by trained abstractors. Incidence of infection was measured as infection episodes per 1000 patient days. The risk ratio (RR) of CVC use for nosocomial blood stream infection was calculated as the infection rate during catheter days divided by the infection rate during noncatheter days. Using a Poisson regression model we examined the adjusted RR of CVC use for nosocomial blood stream infection, controlling for patient characteristics and illness severity at admission. Interinstitutional variations in CVC-related infection risks were examined by stratified analyses.Results.CVC were used in 22.5% of patients. The incidence of nosocomial blood stream infection was 2.9 per 1000 noncatheter days, 7.2 per 1000 umbilical venous catheter days, 13.1 per 1000 percutaneous catheter days and 12.1 per 1000 Broviac catheter days. The RR for nosocomial blood stream infection, adjusted for differences in patient characteristics and admission illness severity, was 2.5 for umbilical venous catheter, 4.6 for percutaneous catheter and 4.3 for Broviac catheter (P< 0.05). There were significant (P< 0.05) risk-adjusted variations in CVC-related infection risks among NICUs.Conclusions.CVC use increased the risk of nosocomial blood stream infection. The risk of nosocomial blood stream infection in percutaneous and Broviac catheters was 70 to 80% higher than in umbilical venous catheters. There was significant variation in CVC-related infection risks among Canadian NICUs.

摘要:
Objective.To provide information on the use and outcomes of palivizumab prophylaxis in children at high risk of serious respiratory syncytial virus (RSV) infection.Design.Observational, prospective, longitudinal, multicenter study.Setting.Eighteen hospitals and pediatric clinics located in six provinces across Canada.Patients.Infants enrolled in the palivizumab Special Access Programme of Canada’s Therapeutic Products Programme throughout the 1999 to 2000 RSV season. Most were premature infants born at ≤32 weeks of gestation and/or had bronchopulmonary dysplasia.Methods and main outcome measures.Neonatal and demographic data were recorded for each subject. The parent/caregiver was contacted on a monthly basis until the end of the RSV season to obtain information on palivizumab utilization and compliance as well as incidence and severity of respiratory infections.Results.There were 444 evaluable subjects who each received 1 to 7 injections of palivizumab for a total of 1702 doses from September 1999 to April 2000. Most subjects received 5 injections with high compliance. Prophylaxis was discontinued in 2% of children. There were 116 clinical events or hospitalizations involving respiratory tract infections reported in 91 children. Eighty-six of these were managed in an outpatient setting, and 30 required hospitalization. The estimated incidence of hospitalization for RSV-positive lower respiratory tract infections (LRTIs) was 2.4%. Hospitalization for RSV LRTI occurred more often in children with bronchopulmonary dysplasia (6.0%) than in those with prematurity only (1.6%).Conclusions.This study demonstrates that prophylaxis with palivizumab during the RSV season was associated with a low rate of hospitalization for RSV-positive LRTIs. Palivizumab was well-tolerated, and compliance was high. The findings confirm the results of the major randomized clinical trial of palivizumab and demonstrate the safety and effectiveness of RSV prophylaxis.

摘要:
Background.To assess tolerance and efficacy of early multitherapy including a protease inhibitor for infants perinatally infected with HIV.Methods.Observational study of tolerance and clinical and immunovirologic evolution in HIV-infected infants treated before the age of 1 year in the French Perinatal Study.Results.Thirty-one infants were included. The median age was 3.7 months at initiation of multitherapy. Clinical stage was C (n= 8), B (n= 5) or A/N (n= 18). The median HIV RNA viral load was 5.8 log copies/ml, and the median CD4 cell percentage was 29%. Median follow-up of treatment was 27 months. Of 31 infants 15 experienced mild to moderate adverse events. No infant had clinical or immunologic progression. The median change in viral load was −2.7 log copies/ml after 3 months, −2.0 log after 12 months and −1.7 log after 24 months of treatment. The proportion of infants with a viral load below 500 copies/ml decreased from 53% at 6 months to 18% at 24 months of treatment. The virologic response was not correlated with viral load at baseline. However, the slope of the viral load decrease during the first month of treatment was predictive of the virologic response at 3 and 6 months. Fourteen infants with a viral load of >500 copies/ml after 6 months of treatment displayed viruses with antiretroviral resistance mutations in reverse transcriptase and/or protease genes.Conclusions.Despite the absence of clinical or immunologic progression, the high frequency of virologic failure associated with genotypic resistance reveals the difficulties associated with implementing antiretroviral multitherapy in infants. Suboptimal doses of protease inhibitor could be a factor contributing to treatment failure.

摘要:
Background.Fluoroquinolones (FQs) have been infrequently used in children, largely because of concern that these agents can cause lesions of the cartilage in juvenile animals. However, the relevance of this laboratory observation to children treated with FQs is unknown. A retrospective, observational study was conducted to assess the incidence and relative risk of tendon or joint disorders (TJDs) that occur after use of selected FQs compared with azithromycin (AZ), a drug with no known effect on cartilage or tendons in humans or animals.Methods.An automated database was searched to identify patients younger than 19 years who had been prescribed ofloxacin (OFX), levofloxacin, ciprofloxacin (CPX), or AZ. Potential cases of TJD occurring within 60 days of a prescription of one of the study drugs were identified based on assignment of a claims diagnosis consistent with a TJD within this period. Verified cases were identified by a blinded review of abstracts of medical records from subjects identified as potential cases.Results.The incidence of verified TJD was 0.82% for OFX (13 of 1593) and CPX (37 of 4531) and was 0.78% for AZ (118 of 15 073). The relative risk of TJD for OFX and CPX compared with AZ was 1.04 (95% confidence interval, 0.55 to 1.84) and 1.04 (95% confidence interval, 0.72 to 1.51), respectively. The distributions of claims diagnoses and time to onset of TJD were comparable for all groups. The most frequently reported category of TJD involved the joint followed by tendon, cartilage and gait disorder.Conclusions.In this observational study involving more than 6000 FQ-treated children, the incidence of TJD associated with selected FQ use in children was <1% and was comparable with that of the reference group, children treated with AZ.

摘要:
Background.Methicillin-resistantStaphylococcus aureus(MRSA) with a narrower antibiotic resistance pattern have emerged. There is a risk for the appearance of resistance during clindamycin therapy of erythromycin-resistant MRSA infections because of the linked resistance mechanisms.Methods.We analyzed clindamycin-susceptible MRSA organisms from children (1987 to 2000) along with clinical data. Antibiotic susceptibilities of organisms were tested, pulsed field gel electrophoresis (PFGE) was done and the linked resistance mechanism was detected by the D test.Results.An average of 11 clindamycin-susceptible MRSA per year were obtained from children since 1993. Of 88 isolates 33 (38%) were erythromycin-resistant. The latter were less often community-acquired (45%vs.69%), more often from infants <1 month of age (24%vs.4%) and less likely to be in the community acquisition-associated PFGE Group 1 (62%vs.87%) than those that were susceptible. The D test was positive in 31 of 33 erythromycin-resistant isolates. A 9-month-old boy with pneumonia/empyema caused by a clindamycin-susceptible, erythromycin-resistant, D test-positive MRSA developed a PFGE-identical clindamycin-resistant isolate and clinical relapse during clindamycin treatment. In contrast a 12-year-old girl with abscesses caused by a similar MRSA developed another abscess after clindamycin therapy, but the organism was unchanged in susceptibility.Conclusions.Erythromycin resistance was present in 38% of clindamycin-susceptible MRSA in children, and clindamycin resistance was detected during treatment in one child. Clindamycin remains a treatment option if the clinician is notified of the risk by the microbiology laboratory and the clinical situation is suitable.
