Introduction
Acute kidney injury (AKI) is significant problem in children with congenital heart disease (CHD) who undergo cardiac surgery. The economic impact of a biomarker-based diagnostic strategy for AKI in pediatric populations undergoing CHD surgery is unknown. The aim of this study was to perform the cost effectiveness analysis of using serum cystatin C (sCysC), urine neutrophil gelatinase-associated lipocalin (uNGAL) and urine liver fatty acid-binding protein (uL-FABP) for the diagnosis of AKI in children after cardiac surgery compared with current diagnostic method (monitoring of serum creatinine (sCr) level).Materials and methods
We developed a decision analytical model to estimate incremental cost-effectiveness of different biomarker-based diagnostic strategies compared to current diagnostic strategy. The Markov model was created to compare the lifetime cost associated with using of sCysC, uNGAL, uL-FABP with monitoring of sCr level for the diagnosis of AKI. The utility measurement included in the analysis was quality-adjusted life years (QALY). The results of the analysis are presented as the incremental cost-effectiveness ratio (ICER).Results
Analysed biomarker-based diagnostic strategies for AKI were cost-effective compared to current diagnostic method. However, uNGAL and sCys C strategies yielded higher costs and lower effectiveness compared to uL-FABP strategy. uL-FABP added 1.43 QALY compared to current diagnostic method at an additional cost of $8521.87 per patient. Therefore, ICER for uL-FABP compared to sCr was $5959.35/QALY.Conclusions
Our results suggest that the use of uL-FABP would represent cost effective strategy for early diagnosis of AKI in children after cardiac surgery.Key words: acute kidney injury, cardiac surgery, children, biomarkers, cost effectiveness analysis 相似文献12.
The aim of this study was to examine the attitudes of preschool, primary, secondary and high school teachers towards inclusive education of children with special educational needs. In addition, the study established the correlation between these attitudes and gender, education level, teaching experience, formal training in the special education field, and the duration and quality of work experience with children with special education needs. The sample comprised 322 teachers from the Serbian province of Vojvodina. The My Thinking about Inclusion Scale (Stoiber, K. C., M. Gettinger, and D. Goetz. 1998. “Exploring Factors Influencing Parents' and Early Childhood Practitioners Beliefs about Inclusion.” Early Childhood Research Quarterly 13 (1): 107–131) was used. The results show that, in general, the participants held neutral attitudes towards inclusive education and more positive expectations regarding the outcomes of inclusion. This study also emphasised teaching performance in an inclusive class as a subject of great concern. The high school and preschool teachers as well as the teachers with previous positive experience with working in an inclusive environment reported more positive attitudes towards inclusive education than those from primary and secondary schools and those with negative experiences with the implementation of inclusive practices. 相似文献

This exploratory case study examined pre-service teachers’ expectations of and attitudes toward the learning and integrating of ICT into their teaching, and their perceptions of the availability and use of ICT in the Teacher Education Program (TEP) and their placement schools. For two years in a row the researchers collected data through online survey and focus group meetings. The findings confirm what has been reported in the literature, but also identify some challenges which may be present internationally in TEPs, such as inadequate access to ICT both in TEPs and in schools, and lack of modeling by tertiary instructors. 相似文献

Introduction:
We examined the cost-effectiveness of the three different D-dimer measurements in the screening of DVT in models with and without calculation of pre-test probability (PTP) score. Moreover, we calculated the minimal cost in DVT detection.Material and methods:
In the group of 192 patients with clinically suspected acute DVT, we examined the three different D-dimer measurements (Innovance D-dimer, Hemosil D-dimer HS and Vidas D-dimer Exclusion II) in combination with and without PTP assessment.Results:
The diagnostic alternative employing Vidas D-dimer Exclusion II assay without and with PTP calculation gave lower incremental cost-effectiveness ratio (ICER) than the alternative employing Hemosil D-dimer HS assay (0.187 Euros vs. 0.998 Euros per one additional DVT positive patient selected for CUS in model without PTP assessment and 0.450 vs. 0.753 Euros per one DVT positive patient selected for CUS in model with PTP assessment). According to sensitivity analysis, the Hemosil D-dimer HS assay was the most cost effective alternative when one patient was admitted to the vascular ambulance per day. Vidas D-dimer Exclusion II assay was the most cost effective alternative when more than one patient were admitted to the vascular ambulance per day. Cost minimisation analysis indicated that selection of patients according to PTP score followed by D-dimer analysis decreases the cost of DVT diagnosis.Conclusions:
ICER analysis enables laboratories to choose optimal laboratory tests according to number of patients admitted to laboratory. Results support the feasibility of using PTP scoring and D-dimer measurement before CUS examination in DVT screening. 相似文献15.

A large number of criteria for evaluating of Internet addiction have been developed, recently. The research of Internet addiction among students of the Technical faculty in Bor, University of Belgrade has been conducted and its results are presented in this paper. The study included 270 students using criteria of Young??s Internet Addiction Test. In history of this University, that was the primarily research of this kind. 相似文献
