OBJECTIVE To establish management index system for rational drug use of key monitoring drugs， and provide reference for the management of key monitoring drugs in the hospitals. METHODS First， the management index system for rational drug use of key monitoring drugs was drafted by collecting the evidence from related medical literature. Next， using a modified Delphi method， twenty experienced experts from the fields of pharmacy， medical practice， healthcare insurance， and finance were selected to participate in two rounds of questionnaire consultations. Based on the expert enthusiasm coefficient， authority coefficient， degree of opinion concentration， and degree of coordination， the final indicators were determined to establish a management index system for rational drug use of key monitored drugs in medical institutions. RESULTS The expert enthusiasm coefficients reached 100% in both rounds of consultation. In first-level， second-level and third-level indicators， the authority coefficients of experts were 0.89， 0.86 and 0.87， and coordination coefficients of the experts in importance score were 0.300 （P＜ 0.05）， 0.125 （P＜0.05） and 0.139 （P＜0.05）， respectively. The average score for the importance of all indicators reached over 3.5， in which the full score ratio ranged from 35% to 100%. Except that the variation coefficient of a third-level indicator “number of specifications purchased for key monitored drugs” was 0.26， the variation coefficients of rest indicators were less than or equal to 0.25. Based on the results of expert consultation， final version of the management index system established in this study， including two first-level indicators （drug procurement and use， and rational drug use）， five second-level indicators （such as the accessibility， cost-effectiveness） and twenty third-level indicators （such as the number of specifications purchased for key monitored drugs， the increase in the cost of key monitored drugs）. CONCLUSIONS The management index system established in this study possesses high reliability and strong operability， and may provide a reference for the management of key monitoring drugs in the hospitals.

Expert consensus, as an important supplement to clinical practice guidelines, supports clinical decision-making when evidence is lacking or controversial. Compared to clinical practice guidelines, the presentation of expert consensus is more diverse. Currently, there are no reporting guidelines for expert consensus in clinical and public health decision-making. The RIGHT (Reporting Items for Practice Guidelines in Healthcare) checklist is the most commonly used international guideline reporting standard, and is often referred to when writing expert consensus. However, the RIGHT checklist does not include a section on consensus formation methods; while the ACCORD (ACcurate COnsensus Reporting Document) checklist includes reporting requirements for consensus formation methods, but not for reporting recommendations. Therefore, this article integrates the RIGHT and ACCORD reporting checklists and proposes an integrated reporting framework (TIMER-DO) to help authors combine these two commonly used international reporting standards and complete the standardized reporting of expert consensus.

Objective:To analyze the epidemiological characteristics of respiratory syncytial virus (RSV) among children in Hebei from 2019 to 2023.Methods:A total of 46 576 lower respiratory tract specimens were collected from hospitalized children in the Children′s Hospital of Hebei Province from 2019 to 2023. Multiple RT-PCR and capillary electrophoresis were used to detect 13 common respiratory pathogens in the specimens, and the results were statistically analyzed.Results:The overall positive rate of RSV was 18.76%(8 739/46 576). The overall positive rates of RSV in male and female children were 18.84%(5 174/27 462) and 18.65%(3 565/19 114), respectively, showing no statistically significant difference between genders (χ 2=0.916, P=0.339). A linear relationship was found between the positive rate of RSV and age ( P<0.01). There was a significant difference in the positive rates of RSV in different years (χ 2=723.71, P<0.01). The positive rate of RSV peaked in the period from December to February from 2019 to 2021. In 2019 and 2020, the positive rates of RSV were very low from May to October, while the positive rate of RSV was above 10% throughout the whole year of 2021 and small off-season epidemics occurred in May and August. The positive rate of RSV was low in 2022, and no significant seasonal change was observed. The rate of RSV infections peaked from April to June in 2023. There were significant differences in the rates of RSV infections before, during and after the COVID-19 epidemic in each age group ( P<0.01). The rate of mixed infections was 29.20%(2 522/8 739), and the most common other respiratory pathogen was human rhinovirus (52.29%, 1 342/2 552 ). Conclusions:RSV is a common pathogen causing respiratory tract infections in children in Hebei, especially in children under 3 years old. After the COVID-19 epidemic, there are off-season RSV epidemics. Given the variations in the epidemiological features of RSV, it is necessary to carry out continuous monitoring of RSV to provide scientific data for the prevention and control of related diseases.

Objective Procurements are important economic activities in public hospitals.This paper aims to strengthen internal control of procurements and standardize procurement management and to improve operational efficiency and achieve high-quality development.Methods On the basis of analyzing the situation and shortcomings of the existing decentralized procure-ment management model,we utilized the five-aspect theory of"personnel,machinery,material,method,and environment",which is commonly used in enterprise quality management,to design a comprehensive procurement management model by engag-ing the actual needs.Results An independent procurement department was established in the hospital.With the department,procurement management was improved through professional training,separation of procurement and management,and construc-tion of information technology.Conclusion The coordinated procurement management model with an independent procurement de-partment can ensure the legality and compliance of procurement work,and realize planned procurement projects,efficient procure-ment processes,high-quality procurement results,and savings in procurement amounts.This assists hospitals in achieving high-quality development and providing a reference for scientifically strengthening procurement management in peer public hospitals.

Objective:To investigate the distribution characteristics of cognition-related lifestyles of elderly in communities and explore the integrated effects on early cognitive decline.Methods:The participants were from the Project of Prevention and Intervention of Neurodegenerative Disease for Elderly in China. A total of 2 537 older adults aged ≥60 years without dementia in the 2015 baseline survey and the 2017 follow-up survey were included. The information about their cognition-related lifestyles, including physical exercise, social interaction, leisure activity, sleep quality, smoking status, and alcohol consumption, were collected through questionnaire survey and the integrated scores were calculated. Multivariate logistic regression analysis was used to assess the association between integrated cognition-related lifestyle score and early cognitive decline.Results:In the 2 537 older adults surveyed, 28.7% had score of 5-6, while only 4.8% had high scores for all 6 healthy lifestyles. Significant differences in healthy lifestyle factor distributions were observed between men and women. Multivariate logistic regression model showed that the risks for early cognitive decline in the older adults who had lifestyle score of 4 and 5-6 were lower than that in those with lifestyle score of 0-3 ( OR=0.683, 95% CI: 0.457-1.019; OR=0.623, 95% CI: 0.398-0.976; trend P=0.030). In the women, the risks for early cognitive decline was lower in groups with score of 4 and 5-6 than in group with score of 0-3 ( OR=0.491, 95% CI: 0.297-0.812; OR=0.556, 95% CI: 0.332-0.929; trend P=0.024). Conclusion:Cognition-related healthy lifestyles are associated with significantly lower risk for early cognitive decline in the elderly, especially in women.

Objective To develop a Traditional Chinese Medicine(TCM)syndrome diagnosis scale suitable for evaluating the overall health status of participants in long-term simulated weightlessness experiments,and preliminarily evaluate its reliability and validity.Methods Based on the understanding of the pathogenesis of TCM in different stages of long-term manned spaceflight,a scale was developed through literature research and expert consultation.Test-retest reliability and internal consistency coefficient were used to test the reliability of the scale.Item analysis and factor principal component analysis were used to evaluate the validity of the scale,and a rotating component matrix was used to analyze the correlation between each item and dimension using 36 volunteers in a 90 days head down bed rest experiment as the research subjects.Results The scale contains eight dimensions and 57 items.The reliability analysis showed that the correlation coefficient of the total score of the scale for the first and second tests of 30 participants was 0.889,indicating high stability of the scale.The Cronbach coefficient of the scale was 0.934,indicating very good internal consistency.The split half reliability after correction was 0.858,indicating a high reliability of the scale.The validity analysis showed that the difference between the high score group and the low score one for each of the 57 items was statistically significant(P<0.01),and the Pearson correlation coefficient between each item and the total score of the scale was greater than 0.4(P<0.001).The cumulative contribution rate of 8 common factors extracted using principal component factor analysis was 55.293%,and the results of rotating component matrix analysis,after applying TCM theory and expert feedback,had a coincidence of up to 87.5%with the initial 8 dimensions,indicating good structural validity of the scale.Conclusion The scale has good reliability and validity,and can diagnose TCM syndromes.It is suitable for long-term simulated weightlessness experiment and provides an objective and quantitative new method for evaluating the subjective feelings of participants.
