Objectives: This study investigated the effects of effort-reward imbalance (ERI) on emergency nurses' turnover intention and the role of depressive symptoms between ERI and turnover intention.Background: Turnover intention is crucial for clinical practice due to its relationship with turnover behaviour and destructive effect on stability of nursing staff. The ERI is a mainstream model to explain job stress, which seems to be one of the key variables, but the direct evidence is not adequate. In addition, there have been only a few studies looking into the complexity of the relationship between ERI and turnover intention, and more research is needed.Methods: This is a cross-sectional study conducted from July to August 2018, and the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines were followed. We employed a standardised questionnaire to collect sociodemographic information and target turnover intention. Hierarchical multiple logistic regression and mediation analyses were performed for the data analyses.Results: This study included responses from 17,582 emergency nurses in China. On turnover intention, ERI exerted both direct effect and indirect mediating effect. The results also indicate that depressive symptoms partially mediated the effect of ERI on turnover intention, and that 27.4% of this effect can be explained by mediating effects. Conclusions:To improve the turnover intention, it is necessary to consider reducing ERI and depressive symptoms of emergency nurses as powerful measures not to be ignored.

Background As effective quality management tools, quality indicators (QIs) are widely used in laboratory medicine. This study aimed to analyze the results of QIs, identify errors and provide quality specifications (QSs) based on the state-of-the-art. Methods Clinical laboratories all over China participated in the QIs survey organized by the National Health Commission of People' Republic of China from 2015 to 2017. Most of these QIs were selected from a common model of QIs (MQI) established by the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC). All participants were asked to submit general information and original QIs data through a medical quality control data collection system. The results of QIs were reported in percentages and sigma, except turnaround time (TAT) which was measured in minutes. The 25th, 50th and 75th percentiles were, respectively, calculated as three levels of QSs, which were defined starting from the model proposed during the 1st Strategic Conference of the EFLM on "Defining analytical performance 15 years after the Stockholm Conference on Quality Specification in Laboratory Medicine". Results A total of 76 clinical laboratories from 25 provinces in China continuously participated in this survey and submitted complete data for all QIs from 2015 to 2017. In general, the performance of all reported QIs have improved or at least kept stable over time. Defect percentages of blood culture contamination were the largest in the pre-analytical phase. Intra-laboratory TAT was always larger than pre-examination TAT. Percentage of tests covered by inter-laboratory comparison was relatively low than others in the intra-analytical phase. The performances of critical values notification and timely critical values notification were the best with 6.0σ. The median sigma level of incorrect laboratory reports varied from 5.5σ to 5.7σ. Conclusions QSs of QIs provide useful guidance for laboratories to improve testing quality. Laboratories should take continuous quality improvement measures in all phases of total testing process to ensure safe and effective tests.

There is huge space for us to enhance and substantial effort is needed in improving and implementing quality management in China.
