OBJECTIVE To establish a multi-dimensional value assessment framework for new antidiabetic drugs based on multi-criteria decision analysis theory， thus providing a theoretical framework and methodology for evidence-informed medical insurance decision-making. METHODS Firstly， multi-dimensional evidence was searched and obtained to provide reliable data for the establishment of the framework. Secondly， in terms of the obtained evidence， the value assessment framework was preliminarily constructed. Its structure， main core criteria， and contextual criteria were determined through focus group discussion. Finally， the criteria and sub-criteria of the framework and their weights were further determined， reasons for inclusion of sub-criteria and the reasonableness of rating scores were evaluated， and methods of assessment were optimized through expert consultation. RESULTS The multi-dimensional value assessment framework for new antidiabetic drugs was composed of core criteria and contextualized criteria， which could be used for quantitative and qualitative value assessment of new drugs， respectively. The core criteria consisted of five dimensions， with affordability （6.31） having the highest weighting score， followed by comparative effectiveness （6.20）， comparative safety （6.01）， cost-effectiveness （5.89）， and quality of evidence （5.46）. After the normalization of weight within sub-criteria， the budget impact on medical insurance had the highest standardized weight， followed by the control of glycated hemoglobin and patient affordability. The contextual criteria included two dimensions， i. e.， innovation and equity. CONCLUSIONS The assessment framework integrates evidence， stakeholders’ values， and decision contexts to enable a multi- dimensional and evidence-based assessment of the value of new antidiabetic drugs.

To explore the influencing factors of perceived stress among frontline nurses during COVID-19, and the role of positive psychological capital in anxiety sensitivity and stress perception, so as to provide evidence for reducing the perceived stress of frontline nurses. From December 2021 to January 2022, 475 frontline nurses from 8 hospitals in X city were investigated by general data questionnaire, positive psychological capital, anxiety sensitivity index and perceived stress scale. The results showed that there were significant differences in nurses’ perceived stress in age, working years, professional title and salary. Perceived stress was positively correlated with anxiety sensitivity, negatively correlated with positive psychological capital, and anxiety sensitivity was negatively correlated with positive psychological capital. Anxiety sensitivity can not only directly predict perceived stress, but also negatively affect perceived stress through positive psychological capital. Therefore, during the epidemic prevention and control in COVID-19, nurses can obtain effective stress coping strategies by strengthening their positive psychological capital, thus reducing their anxiety and perceived stress, and better providing high-quality nursing services for patients.
