Prioritizing strategies for preventing medication errors and adverse drug events in pediatric inpatients.

Abstract: Objectives. Medication errors in pediatric inpatients occur at similar rates as in adults but have 3 times the potential to cause harm. Error prevention strategies in this setting remain largely untested. The objective of this study was to classify the major types of medication errors in pediatric inpatients and to determine which strategies might most effectively prevent them. Methods. A prospective cohort study was conducted of 1020 patients who were admitted to 2 academic medical centers during a 6-week period in April and May 1999. Medication errors were characterized by subtype. Physician raters evaluated error prevention strategies and identified those that might be most effective in preventing errors. Results. Of 10 778 medication orders reviewed, 616 contained errors. Of these, 120 (19.5%) were classified as potentially harmful, including 115 potential adverse drug events (18.7%) and 5 preventable adverse drug events (0.8%). Most errors occurred at the ordering stage (74%) and involved errors in dosing (28%), route (18%), or frequency (9%). Three interventions might have prevented most potentially harmful errors: 1) computerized physician order entry with clinical decision support systems (76%); 2) ward-based clinical pharmacists (81%); and 3) improved communication among physicians, nurses, and pharmacists (86%). Interrater reliability of error prevention strategy assignment was good (agreement: 0.92; κ: 0.82). Conclusions. Of the assessed interventions, computerized physician order entry with clinical decision support systems; ward-based clinical pharmacists; and improved communication among physicians, nurses, and pharmacists had the greatest potential to reduce medication errors in pediatric inpatients. Development, implementation, and assessment of such interventions in the pediatric inpatient setting are needed.

Antibiotic-Resistant Streptococcus pneumoniae in the Heptavalent Pneumococcal Conjugate Vaccine Era: Predictors of Carriage in a Multicommunity Sample

Abstract: Author(s): Finkelstein, Jonathan A; Huang, Susan S; Daniel, James; Rifas-Shiman, Sheryl L; Kleinman, Ken; Goldmann, Donald; Pelton, Stephen I; DeMaria, Alfred; Platt, Richard | Abstract: OBJECTIVE:Despite immunization with heptavalent pneumococcal conjugate vaccine (PCV7), the rising prevalence of antibiotic resistance makes Streptococcus pneumoniae a continuing threat to child health. Data on carriage of resistant organisms by healthy children in communities in which immunization with PCV7 has been implemented will help to define and decrease these risks further. METHODS:Children who were l7 years old, resided in a study community, and presented for routine well care or a "sick" visit between March 13 and May 11, 2001, at 31 primary care practices in 16 geographically distinct Massachusetts communities were studied. Consenting parents provided demographic information and data on potential risk factors for carriage of S pneumoniae and of penicillin-nonsusceptible S pneumoniae (PNSP). S pneumoniae isolates from nasopharyngeal specimens were tested for resistance to commonly used antibiotics including penicillin, ceftriaxone, erythromycin, and trimethoprim/sulfamethoxazole. Isolates were serotyped and grouped into PCV7-included serotypes, potentially cross-reactive serotypes (ie, an organism of a serogroup included in the vaccine), or non-PCV7 serotypes. Diagnosis on the day of collection, history of recent antibiotic use, and history of PCV7 immunization were obtained by chart review. Separate bivariate and multivariate analyses were performed to identify correlates of colonization with S pneumoniae and colonization with PNSP, accounting for clustering within communities. RESULTS:S pneumoniae was isolated from the nasopharynx of 190 (26%) of the 742 children studied. Of the 166 tested, 33% were nonsusceptible to penicillin, with 14% showing intermediate susceptibility (minimum inhibitory concentration [MIC] 0.12-1.0) and 19% fully resistant (MIC g or =2). Nonsusceptibility to other antibiotics was common, including ceftriaxone (14%), erythromycin (22%), and trimethoprim/sulfa (31%); 20% of S pneumoniae isolates were not susceptible to g or =3 antibiotics. Thirty-six percent of isolates were of serotypes covered by PCV7; 30% were of PCV7 serogroups and potentially cross-reactive, but not 1 of the 7 included serotypes; and 34% were unrelated to PCV7 serogroups. Nonsusceptibility to penicillin was more common in PCV7-included strains (45%) and potentially cross-reactive strains (51%) than in non-PCV7 serotypes (8%). Risk factors for PNSP colonization included child care attendance (odds ratio [OR]: 3.9; 95% confidence interval [CI]: 2.3-6.5), current respiratory tract infection (OR: 4.7; 95% CI: 2.5-8.6), and recent antibiotic use (OR: 1.7; 95% CI: 1.0-2.8). PCV7 immunization was associated with decreased carriage of PCV7-included serotypes but not with an overall decrease in S pneumoniae colonization or with a decline in PNSP colonization. CONCLUSIONS:In this multicommunity sample, pneumococcal antibiotic resistance was common and was most frequently found in PCV7-included and PCV7 serogroup strains. The long-term impact of PCV7 immunization will be partially determined by the protection that it affords against invasive infection with potentially cross-reactive serotypes, as well as the virulence and future resistance patterns of unrelated serotypes.

A clinical practice guideline for treatment of septic arthritis in children: efficacy in improving process of care and effect on outcome of septic arthritis of the hip.

Abstract: Background: The development of clinical practice guidelines is a central precept of the evidence-based-medicine movement. The purposes of this study were to develop a guideline for the treatment of septic arthritis in children and to evaluate its efficacy with regard to improving the process of care and its effect on the outcome of septic arthritis of the hip in children. Methods: A clinical practice guideline was developed by an interdisciplinary expert committee using evidence-based techniques. Efficacy was evaluated by comparing a historical control group of thirty consecutive children with septic arthritis of the hip managed before the utilization of the guideline with a prospective cohort group of thirty consecutive children treated with use of the guideline. Benchmark parameters of process and outcome were compared between groups. Results: The patients treated with use of the guideline, compared with those treated without use of the guideline, had a significantly higher rate of performance of initial and follow-up C-reactive protein tests (93% compared with 13% and 70% compared with 7%), lower rate of initial bone-scanning (13% compared with 40%), lower rate of presumptive drainage (13% compared with 47%), greater compliance with recommended antibiotic therapy (93% compared with 7%), faster change to oral antibiotics (3.9 compared with 6.9 days), and shorter hospital stay (4.8 compared with 8.3 days). There were no significant differences between the groups with regard to other process variables, and there were no significant differences with regard to outcome variables, including readmission to the hospital, recurrent infection, recurrent drainage, development of osteomyelitis, septic osteonecrosis, or limitation of motion. Conclusions: Patients treated according to the septic arthritis clinical practice guideline had less variation in the process of care and improved efficiency of care without a significant difference in outcome. Level of Evidence: Therapeutic study, Level III-2 (retrospective cohort study). See Instructions to Authors for a complete description of levels of evidence.

Evaluation and Development of Potentially Better Practices to Prevent Neonatal Nosocomial Bacteremia

Abstract: Objective. Six neonatal intensive care units (NICUs) that are members of the Vermont Oxford National Evidence-Based Quality Improvement Collaborative for Neonatology collaborated to reduce infection rates. There were 7 centers in the original focus group, but 1 center left the collaborative after 1 year. The objective of this study was to develop strategies to decrease nosocomial infection rates in NICUs. Methods. The process included a comprehensive literature review, internal practice analyses, benchmark studies, and development of practical experience through rapid-cycle changes, subsequent analysis, and feedback. This process led to 3 summary statements on potentially better practices in handwashing, approach to nosocomial sepsis evaluations, and central venous catheter management. Results. These statements provide a basis for an evidence-based approach to lowering neonatal intensive care unit nosocomial infection rates. Conclusions. The 2-year process also led to changes in the culture and habits of the institutions involved, which should in turn have long-term effects on other aspects of quality improvement.

Use of an Alcohol-Based Hand Rub and Quality Improvement Interventions to Improve Hand Hygiene in a Russian Neonatal Intensive Care Unit

Abstract: Background Hand hygiene (HH) is critical to infection control, but compliance is low. Alcohol-based antiseptics may improve HH. HH practices in Russia are not well described, and facilities are often inadequate. Setting Four 6-bed units in a neonatal intensive care unit in St. Petersburg, Russia. Methods Prospective surveillance of HH compliance, nosocomial colonization, and antibiotic administration was performed from January until June 2000. In February 2000, alcohol-based hand rub was provided for routine HH use. Eight weeks later, a quality improvement intervention was implemented, consisting of review of interim data, identification of opinion leaders, posting of colonization incidence rates, and regular feedback. Means of compliance, colonization, and antibiotic use were compared for periods before and after each intervention. Results A total of 1,027 events requiring HH were observed. Compliance was 44.2% before the first intervention, 42.3% between interventions, and 48% after the second intervention. Use of alcohol rose from 15.2% of HH indications to 25.2% between interventions and 41.5% after the second intervention. The incidence of nosocomial colonization (per 1,000 patient-days) with Klebsiella pneumoniae was initially 21.5, decreased to 4.7, and then was 3.2 in the final period. Rates of antibiotic and device use also decreased. Conclusions HH may have increased slightly, but the largest effect was a switch from soap and water to alcohol which may have been associated with decreased cross-transmission of Klebsiella, although this may have been confounded by lower device use. Alcohol-based antiseptic may be an improvement over current practices, but further research is required.

Misconceptions About Colds and Predictors of Health Service Utilization

Abstract: Objective. Colds accounted for 1.6 million emergency department (ED) visits and 25 million ambulatory visits by children and adults in 1998. Although most colds are caused by viruses and do not require medical intervention, many families seek health care for the treatment of colds. Parental misconceptions about the cause and appropriate treatment of colds may contribute to unnecessary health service utilization. The objective of this study was to determine predictors of reported ED use and ambulatory care use for colds among families with young children. Methods. This study was an observational, prospective cohort study to determine attack rates for respiratory illnesses within families that have at least 1 child who is 6 months to 5 years of age and enrolled in out-of-home child care. Families were randomly selected from 5 pediatric practices in Massachusetts and were considered eligible when the child was enrolled in child care with at least 5 other children for ≥10 hours per week. Enrolled families were asked to complete a survey that assessed knowledge about colds, antibiotic indications, and frequency of health service utilization. Predictors of self-reported use of health care services were assessed in multivariate logistic regression models. Results. Of the 261 families enrolled in the study, 197 families (75%) returned completed surveys. Although 93% of parents understood that viruses caused colds, 66% of parents also believed that colds were caused by bacteria. Fifty-three percent believed that antibiotics were needed to treat colds. Parents reported that they would visit the ED (23%) or their doctor’s office (60%) when their child had a cold. Predictors of ED use on multivariate analysis included Medicaid insurance (odds ratio [OR]: 17.6 [2.2–139.3]), history of wheezing (OR: 18.3 [4.4–75.8]), and belief that antibiotics treat colds (OR: 4.2 [1.4–12.9]). Predictors of ambulatory care use included parent younger than 30 years (OR: 10.0 [1.6–64.3]), history of wheezing (OR: 5.6 [1.1–29.7]), and belief that antibiotics treat colds (OR: 3.8 [1.7–8.5]). Conclusions. Misconceptions about the appropriate treatment of colds are predictive of increased health service utilization. Targeted educational interventions for families may reduce inappropriate antibiotic-seeking behavior and unnecessary health service utilization for colds.

Administrative Databases Provide Inaccurate Data for Surveillance of Long-Term Central Venous Catheter-Associated Infections

Abstract: BACKGROUND: Efficient methods are needed to monitor infections associated with long-term central venous catheters (CVCs) in both inpatient and outpatient settings. Automated medical records and claims data have been used for surveillance of these infections without evaluation of their accuracy or validity. OBJECTIVE: To determine the feasibility of using electronic records to identify CVC placement and design a system for identifying CVC-associated infections. DESIGN AND SETTING: Retrospective cohort study at an HMO and two teaching hospitals in Boston, one adult (hospital A) and one pediatric (hospital B), between January 1991 and December 1997. Tunneled catheters, totally implanted catheters, and hemodialysis catheters were examined. Claims databases of both the HMO and the hospitals were searched for 10 CPT codes, 2 ICD-9 codes, and internal charge codes indicating CVC insertion. Lists were compared with each other and with medical records for correlation and accuracy. PATIENTS: All members of the HMO who had a CVC inserted at one of the two hospitals during the study period. RESULTS: There was wide variation in the CVC insertions identified in each database. Although ICD-9 codes at each hospital and CPT/ICD-9 combinations at the HMO found similar total numbers of CVCs, there was little overlap between the individuals identified (62% for hospital A with HMO and 4% for hospital B). CONCLUSION: Claims data from different sources do not identify the same CVC insertion procedures. Current administrative databases are not ready to be used for electronic surveillance of CVC-associated complications without extensive modification and validation (Infect Control Hosp Epidemiol

Notifying emergency department patients of negative test results: pitfalls of passive communication.

Abstract: ObjectiveMany emergency departments that perform a high volume of group A Streptococcus throat cultures inform patients or parents that unless they are notified of a positive result they can assume that their throat culture result is negative. Thus, positive throat culture results are communicated a
