Comparison of ultrasound versus computed tomography for the detection of kidney stones in the pediatric population: a clinical effectiveness study.

BACKGROUND: The incidence of pediatric nephrolithiasis in the United States is increasing. There is a paucity of literature comparing the diagnostic performance of computed ultrasound (US) to tomography (CT) in the pediatric population. OBJECTIVE: To determine the diagnostic performance of renal US for nephrolithiasis in children using a clinical effectiveness approach. MATERIALS AND METHODS: Institutional review board approval with a waiver of informed consent was obtained for this retrospective, HIPAA-complaint investigation. Billing records and imaging reports were used to identify children (≤18 years old) evaluated for nephrolithiasis by both US and unenhanced CT within 24 h between March 2012 and March 2017. Imaging reports were reviewed for presence, number, size and location of kidney stones. Diagnostic performance of US (reference standard=CT) was calculated per renal unit (left/right kidney) and per renal sector (four sectors per kidney). For sector analysis, US was considered truly positive if a stone was identified at CT in the same or an adjacent sector. RESULTS: There were 68 renal stones identified by CT in 30/69 patients (43%). Mean patient age was 14.7±3.6 years, and 35 were boys. For detecting nephrolithiasis in any kidney, US was 66.7% (48.8-80.8%) sensitive and 97.4% (86.8-99.9%) specific (positive predictive value=95.2% [77.3-99.8%], negative predictive value=79.2% [65.7-88.3%], positive likelihood ratio=26.0). Per renal sector, US was 59.7% (46.7-71.4%) sensitive and 97.4% (95.5-98.5%) specific (positive predictive value=72.3% [58.2-83.1%], negative predictive value=95.4% [93.2-96.9%], positive likelihood ratio=22.5). Of the 30 stones not detected by US, only 3 were >3 mm at CT. CONCLUSION: In clinical practice, US has high specificity for detecting nephrolithiasis in children but only moderate sensitivity and false negatives are common.

Frequency and Severity of Acute Allergic-Like Reactions to Intravenously Administered Gadolinium-Based Contrast Media in Children.

OBJECTIVES: The purpose of this study is to determine the frequency and severity of acute allergic-like reactions to gadolinium-based contrast media (GBCM) in children before, during, and after the transition from gadopentetate dimeglumine to gadoterate meglumine as our primary clinical GBCM. MATERIALS AND METHODS: Institutional review board approval was obtained for this Health Insurance Portability and Accountability Act-compliant retrospective investigation. Allergic-like reactions to GBCM in pediatric patients were retrospectively assessed from January 2009 to January 2017, which included a departmental change of GBCM from gadopentetate dimeglumine to gadoterate meglumine. Allergic-like reactions were identified from departmental and hospital databases. The number of doses of GBCM was obtained from billing data. Allergic-like reaction frequencies for each GBCM were calculated and compared using the chi-squared test. RESULTS: A total of 32,365 administrations of GBCM occurred during the study period (327 for gadofosveset trisodium; 672 for gadoxetate disodium; 12,012 for gadoterate meglumine; and 19,354 for gadopentetate dimeglumine). Allergic-like reactions occurred after 21 (0.06%) administrations. Reaction frequencies were not significantly different among the GBCM (0.3% gadofosveset trisodium; 0% gadoxetate disodium, 0.06% gadoterate meglumine, 0.08% gadopentetate dimeglumine; P > 0.05). Ten (47.6%) reactions were mild, 10 (47.6%) were moderate, and 1 (4.8%) was severe. The overall reaction frequency peaked during the 6-month transition period from gadopentetate dimeglumine to gadoterate meglumine (0.20%), compared with 0.07% pretransition (P = 0.048) and 0.04% posttransition (P = 0.0095). CONCLUSION: Allergic-like reactions to GBCM in children are rare. Gadoterate meglumine has a reaction frequency that does not significantly differ from other GBCMs. During the transition from gadopentetate dimeglumine to gadoterate meglumine, an increase in the frequency of reported allergic-like reactions was observed, likely reflective of the Weber effect.

Information Quality Challenges of Patient-Generated Data in Clinical Practice.

A characteristic trend of digital health has been the dramatic increase in patient-generated data being presented to clinicians, which follows from the increased ubiquity of self-tracking practices by individuals, driven, in turn, by the proliferation of self-tracking tools and technologies. Such tools not only make self-tracking easier but also potentially more reliable by automating data collection, curation, and storage. While self-tracking practices themselves have been studied extensively in human-computer interaction literature, little work has yet looked at whether these patient-generated data might be able to support clinical processes, such as providing evidence for diagnoses, treatment monitoring, or postprocedure recovery, and how we can define information quality with respect to self-tracked data. In this article, we present the results of a literature review of empirical studies of self-tracking tools, in which we identify how clinicians perceive quality of information from such tools. In the studies, clinicians perceive several characteristics of information quality relating to accuracy and reliability, completeness, context, patient motivation, and representation. We discuss the issues these present in admitting self-tracked data as evidence for clinical decisions.

An evaluation of the Florence Nightingale Foundation scholarships.

The Florence Nightingale Foundation (FNF) is a charity that awards scholarships in leadership, travel and research to nurses, midwives and other healthcare professionals to promote excellence in practice. The FNF offers mentoring support to scholars, and provides support with career development and writing articles for publication, in addition to the financial award. The leadership scholarships are bespoke: leadership scholars can access a range of development opportunities that are specially commissioned for them, and select their programme of study and experiences, based on their individual needs. All scholarships provide opportunities to represent the FNF and to meet other scholars at the FNF annual conference. This article provides an overview of the FNF scholarships, based on the findings of two evaluations that demonstrated the value of these scholarships in improving services for patients and carers, as well as enhancing the careers of individual scholars.

A review of randomized controlled trials of medical record powered clinical decision support system to improve quality of diabetes care.

BACKGROUND: A gap between current diabetes care practice and recommended diabetes care standards has consistently been reported in the literature. Many IT-based interventions have been developed to improve adherence to the quality of care standards for chronic illness like diabetes. OBJECTIVE: The widespread implementation of electronic medical/health records has catalyzed clinical decision support systems (CDSS) which may improve the quality of diabetes care. Therefore, the objective of the review is to evaluate the effectiveness of CDSS in improving quality of type II diabetes care. Moreover, the review aims to highlight the key indicators of quality improvement to assist policy makers in development of future diabetes care policies through the integration of information technology and system. SELECTION OF STUDY: Setting inclusion criteria, a systematic literature search was conducted using Medline, Web of Science and Science Direct. Critical Appraisal Skills Programme (CASP) tools were used to evaluate the quality of studies. Eight randomized controlled trials (RCTs) were selected for the review. In the selected studies, seventeen clinical markers of diabetes care were discussed. Three quality of care indicators were given more importance in monitoring the progress of diabetes care, which is consistent with National Institute for Health and Care Excellence (NICE) guidelines. The presence of these indicators in the studies helped to determine which studies were selected for review. Clinical- and process-related improvements are compared between intervention group using CDSS and control group with usual care. Glycated hemoglobin (HbA1c), low density lipid cholesterol (LDL-C) and blood pressure (BP) were the quality of care indicators studied at the levels of process of care and clinical outcome. FINDINGS: The review has found both inconsistent and variable results for quality of diabetes care measures. A significant improvement has been found in the process of care for all three measures of quality of diabetes care. However, weak to modest positive results are observed for the clinical measures of the diabetes care indicators. In addition to this, technology adoption of CDSS is found to be consistently low. CONCLUSION: The review suggests the need to conduct further empirical research using the critical diabetes care indicators (HbA1c, LDL-C and BP) to ascertain if CDSS improves the quality of diabetes care. Research designs should be improved, especially with regard to baseline characteristics, sample size and study period. With respect to implementation of CDSS, rather than a sudden change of clinical work practice, there should instead be an incremental, gradual adoption of technology that minimizes the disruption in clinical workflow.
