Bone metabolism in children with asthmatreated with inhaled beclomethasone dipropionate

Previous studies have shown that inhaled corticosteroids can affect bone metabolism in adults. A study to assess the effect of inhaled beclomethasone, 300 to 800 micrograms/day for at least 6 months (mean 25 months), was therefore undertaken in children. In part 1 of the study, 18 children with asthma, aged 4 to 17 years (mean 10.1 years), were compared with an age- and sex-matched group of children with asthma not treated with corticosteroids. In part 2, eight more pairs were compared. Comparisons were also made with 61 healthy children. Bone mineral density measured by radiographic absorptiometry, and bone mineral content measured by single-photon absorptiometry and by dual-energy x-ray absorptiometry, showed no significant differences. Serum levels of calcium, magnesium, zinc, total alkaline phosphatase, bone specific alkaline phosphatase, parathyroid hormone, 25-hydroxyvitamin D, and 1,25-dihydroxyvitamin D also showed no differences. The activity of tartrate-resistant acid phosphatase, a marker of bone resorption, was significantly lower in the beclomethasone group than in both the asthma control and the normal control groups, but urine calcium excretion did not differ. Patients with asthma had lower serum osteocalcin and higher serum copper levels than control subjects without asthma, but treatment with beclomethasone did not affect these values. We conclude that inhaled beclomethasone (up to 800 micrograms/day) does not reduce bone mineralization or increase bone resorption. Effects on bone formation were difficult to assess because asthma per se caused a significant reduction in osteocalcin, a sensitive marker of bone formation.

Hospital admission medication reconciliation in medically complex children: an observational study

Objective To evaluate admission medication reconciliation in children with medically complex conditions (MCC) by determining the availability and accuracy of five information sources and characterising admitting order errors. Design Prospective quality improvement cohort study. Setting Tertiary care free-standing childrens hospital in the Intermountain west, USA. Participants 23 children with MCC identified from 219 admissions between 16 December 2004 and 7 January 2005. Intervention Medication reconciliation at hospital admission using information from five sources. Main outcomes The accuracy of information sources was determined by sensitivity and specificity compared with verified outpatient medication lists. Errors were determined by comparing admitting orders with reconciled inpatient medication lists and categorised by frequency, type and clinical risk. Results Children with MCC averaged 5.3 chronic medications. The reconciliation process took an average of 90 min. Availability/sensitivity/specificity respectively were parents 52%/0.75/0.96, pharmacy 61%/0.64/0.74, primary provider 43%/0.25/0.86, last admission electronic health record 87%/0.74/0.33 and admitting history 65%/0.31/0.94. Thirty-nine errors were identified in 182 admission medications (21%) including 17 omissions, affecting 13 patients (57%). The estimated clinical risk, if an adverse drug event had occurred, was serious or life-threatening in five instances. Conclusions In children with MCC admitted at our institution during the study period, no medication information source was optimally available, sensitive and specific. Admitting order medication errors affected more than half of patients, the most common being omissions. Efforts to improve medication reconciliation at hospital admission in this population must account for availability and accuracy of information sources and medication omissions at the time of hospital admission.

Integration strategies for using virtual patients in clinical clerkships.

Purpose To explore students’ perceptions of virtual patient use in the clinical clerkship and develop a framework to evaluate effects of different integration strategies on students’ satisfaction and perceptions of learning effectiveness with this innovation. Method A prospective, multiinstitutional study was conducted at six schools’ pediatric clerkships to assess the impact of integrating Web-based virtual patient cases on students’ perceptions of their learning during 2004–2005 and 2005–2006. Integration strategies were designed to meet the needs of each school, and integration was scored for components of virtual patient use and elimination of other teaching methodologies. A student survey was developed, validated, and administered at the end of the clerkship to 611 students. Data were analyzed using confirmatory factor analysis and structural equation modeling. Results A total of 545 students (89%) completed the survey. Overall student satisfaction with the virtual patients was high; students reported that they were more effective than traditional methods. The structural model demonstrated that elimination of other teaching methodologies was directly associated with perceived effectiveness of the integration strategies. A higher use score had a significant negative effect on perceived integration, but a positive effect on perceived knowledge and skills gain. Students’ positive perceptions of integration directly affected their satisfaction and perception of the effectiveness of their learning. Conclusions Integration strategies balancing the use of virtual patients with elimination of some other requirements were significantly associated with students’ satisfaction and their perceptions of improved knowledge and skills.

The Joint Commission Children’s Asthma Care Quality Measures and Asthma Readmissions

BACKGROUND AND OBJECTIVES: The Joint Commission introduced 3 Children’s Asthma Care (CAC 1–3) measures to improve the quality of pediatric inpatient asthma care. Validity of the commission’s measures has not yet been demonstrated. The objectives of this quality improvement study were to examine changes in provider compliance with CAC 1–3 and associated asthma hospitalization outcomes after full implementation of an asthma care process model (CPM). METHODS: The study included children aged 2 to 17 years who were admitted to a tertiary care children’s hospital for acute asthma between January 1, 2005, and December 31, 2010. The study was divided into 3 periods: preimplementation (January 1, 2005–December 31, 2007), implementation (January 1, 2008–March 31, 2009), and postimplementation (April 1, 2009–December 31, 2010) periods. Changes in provider compliance with CAC 1–3 and associated changes in hospitalization outcomes (length of stay, costs, PICU transfer, deaths, and asthma readmissions within 6 months) were measured. Logistic regression was used to control for age, gender, race, insurance type, and time. RESULTS: A total of 1865 children were included. Compliance with quality measures before and after the CPM implementation was as follows: 99% versus 100%, CAC-1; 100% versus 100%, CAC-2; and 0% versus 87%, CAC-3 (P < .01). Increased compliance with CAC-3 was associated with a sustained decrease in readmissions from an average of 17% to 12% (P = .01) postimplementation. No change in other outcomes was observed. CONCLUSIONS: Implementation of the asthma CPM was associated with improved compliance with CAC-3 and with a delayed, yet significant and sustained decrease in hospital asthma readmission rates, validating CAC-3 as a quality measure. Due to high baseline compliance, CAC-1 and CAC-2 are of questionable value as quality measures.

Improving transitions of care at hospital discharge--implications for pediatric hospitalists and primary care providers.

&NA; Delays, omissions, and inaccuracy of discharge information are common at hospital discharge and put patients at risk for adverse outcomes. We assembled an interdisciplinary team of stakeholders to evaluate our current discharge process between hospitalists and primary care providers (PCPs). We used a fishbone diagram to identify potential causes of suboptimal discharge communication to PCPs. Opportunities for improvement (leverage points) to achieve optimal transfer of discharge information were identified using tally sheets and Pareto charts. Quality improvement strategies consisted of training and implementation of a new discharge process including: (1) enhanced PCP identification at discharge, (2) use of an electronic discharge order and instruction system, and (3) autofaxing discharge information to PCPs. The new discharge processs impact was evaluated on 2,530 hospitalist patient discharges over a 34‐week period by measuring: (1) successful transfer of discharge information (proportion of discharge information sheets successfully faxed to PCPs), (2) timeliness (proportion of sheets faxed within 2 days of discharge), and (3) content (presence of key clinical elements in discharge sheets). Postintervention, success, and timeliness of discharge information transfer between pediatric hospitalists and PCPs significantly improved while content remained high.

Quality of Care for Children Hospitalized With Asthma

OBJECTIVES. The goals were (1) to identify evidence-based clinical process measures that are appropriate, feasible, and reliable for assessing the quality of inpatient asthma care for children and (2) to evaluate provider compliance with these measures. METHODS. Key asthma quality measures were identified by using a modified Rand appropriateness method, combining a literature review of asthma care evidence with a consensus panel. The feasibility and reliability of obtaining these measures were determined through manual chart review. Provider compliance with these measures was evaluated through retrospective manual chart review of data for 252 children between 2 and 17 years of age who were admitted to a tertiary care childrens hospital in 2005 because of asthma exacerbations. RESULTS. Nine appropriate, feasible, reliable, clinical process measures of inpatient asthma care were identified. Provider compliance with these measures was as follows: acute asthma severity assessment at admission, 39%; use of systemic corticosteroid therapy, 98%; use of oral (not intravenous) systemic corticosteroid therapy, 87%; use of ipratropium bromide restricted to <24 hours after admission, 71%; use of albuterol delivered with a metered-dose inhaler (not nebulizer) for children >5 years of age, 20%; documented chronic asthma severity assessment, 22%; parental participation in an asthma education class, 33%; written asthma action plan, 5%; scheduled follow-up appointment with the primary care provider at discharge, 22%. CONCLUSIONS. Nine appropriate, feasible, reliable, clinical process measures of inpatient asthma care were identified. Provider compliance across these measures was highly variable but generally low. Our study highlights opportunities for improvement in the provision of asthma care for hospitalized children. Future studies are needed to confirm these findings in other inpatient settings.

Induction of cyclooxygenase-2 by human monocytes exposed to group B streptococci

Group B streptococcal (GBS) infections are associated with high morbidity and mortality. The molecular pathways mediating the pathophysiological events in GBS infection are not fully delineated. Cyclooxygenases (COX) are the enzymes that convert arachidonate to active eicosanoids. To identify the effects of GBS on eicosanoid metabolism and regulatory mechanisms, we exposed human monocytes to GBS and found that they secreted prostaglandin E2, prostacyclin, and thromboxane A2. Exposure to GBS caused monocytes to express COX‐2 mRNA and protein in both a time‐ and concentration‐dependent manner that correlated with eicosanoid production. COX‐1 protein was unchanged. Addition of the anti‐inflammatory cytokines interleukin (IL)‐4 or IL‐10 markedly attenuated GBS‐induced COX‐2 protein accumulation after GBS exposure, as did inhibition of p38 MAPK. Our experiments are the first to show that exposure of monocytes to a gram‐positive bacterium (GBS) results in induction of functional COX‐2, suggesting that eicosanoids may play important roles in the pathogenesis of GBS infections.

Delays in discharge in a tertiary care pediatric hospital

BACKGROUND Delays in discharges affect both efficiency and timeliness of care; 2 measures of quality of inpatient care. OBJECTIVE Describe number, length, and type of delays in hospital discharges. Characterize impact of delays on overall length of stay (LOS) and costs. DESIGN Prospective observational cohort study. SETTING Tertiary-care childrens hospital. PATIENTS All children on 2 medical teams during August 2004. INTERVENTION Two research assistants presented detailed data of patient care (from daily rounds) to 2 physicians who identified delays and classified the delay type. Discharge was identified as delayed if there was no medical reason for the patient to be in the hospital on a given day. MEASUREMENTS Delays were classified using a validated and reliable instrument, the Delay Tool. LOS and costs were extracted from an administrative database. RESULTS Two teams cared for 171 patients. Mean LOS and costs were 7.3 days (standard deviation [SD] 14.3) and

What Makes a Great Clinical Teacher in Pediatrics? Lessons Learned From the Literature

170,000 in costs (8.9% of hospital costs); 42.3% of the delays resulted from physician behavior, 21.8% were related to discharge planning, 14.1% were related to consultation, and 12.8% were related to test scheduling. CONCLUSIONS Almost one-fourth of patients in this 1-month period could have been discharged sooner than they were. Impact of delays on LOS and costs are substantial. Interventions will need to address variations in physician criteria for discharge, more efficient discharge planning, and timely scheduling of consultation and diagnostic testing.
