In vitro diagnostic technology is an important aid for disease prevention,treatment,and prognostic monitoring.The de-velopment of its new technologies,methods and products is of great significance for improving medical quality and protecting public health.On the basis of exploring the mechanism of health impact of in vitro diagnostic technology,it takes dry chemical method and wet chemical method as an example,and compares the economy of the two diagnostic technologies for hyperkalemia diagnosis from the perspective of health system,with a view to draw references for the practical application and evaluation of new in vitro diagnostic techniques,methods and products in the future.

Health Technology Assessment(HTA)was introduced to China in the 1990s,and its development has now reached the stage of exploring its role in providing recommendations for policy making.In recent years,health technology assessment has been paid much more attention from the aspect of macro policy.Health technology assessment focuses on health and medical insurance decision making and is playing an increasingly important role.However,as time goes by,analysis based on old data may be not suitable for guiding new decisions.It is necessary to construct Living HTA to update HTA results in time and reduce uncertainty of decision-making.It introduces methods and challenges for constructing Living HTA,and proposes directions for exploration based on the current state of HTA development in China.

Objective:To explore the health economic evaluation methods of disease screening,providing insights for scholars conducting related research.Methods:By integrating relevant content from modem epidemiology,health statistics,and health economics,it investigates the differences in conducting health economic evaluations of disease screening using authenticity indicators(sensitivity,specificity)and predictive value indicators(positive predictive value,negative predictive value),and combines empirical studies with cases from the literature.Results:Authenticity indicators(sensitivity,specificity)are intrinsic measures of diagnostic tests,unaffected by the disease prevalence in the sample population,making them more suitable for conducting health economic evaluations of disease screening.Moreover,authenticity indicators are easy to obtain,and the model calculations are straightforward and convenient.Case study results demonstrate that compared to risk score screening,the Incremental Cost-Effectiveness Ratio(ICER)of fasting plasma glucose(FPG)testing for type 2 diabetes is 626,indicating that for every additional diabetic patient identified through risk score screening,an extra 626 yuan is spent.Conclusion:It is recommended to use authenticity indicators for conducting health economic evaluations of disease screening,standardize the path methods for model selection,and continuously improve the evidence quality of health economic evaluations of disease screening in China.

Objective It conducted a rapid health technology assessment to evaluate the comparative safety,efficacy and economy of tumor treating fields(TTFields)combined with temozolomide treatment versus temozolomide(TMZ)alone for patients with glioblastoma(GBM).Methods It provided an extensive electronic search of databases,including PubMed,Embase,Cochrane Library,CNKI,and WanFang Data,to collect clinical evidence and health economic evaluations related to the,safety,efficacy,and economy of TTFields for Glioblastoma patients.The search covered literature from inception to July,2023,and assessed the risk of bias in the included studies.Descriptive analyses and data summaries were performed.Results A total of 19 references were included,comprising 5 randomized controlled trials,3 retrospective studies,8 systematic reviews or meta-analyses,and 3 cost-effectiveness analysis(CEA)studies.The quality of the literature evidence was heterogeneous.Recent meta-analyses mostly support the conclusion that TTFields combined with TMZ treatment provides a survival benefit compared to standard TMZ alone.However,the cost-effectiveness analysis literature from 2 countries showed different results,likely due to differences in socioeconomic levels,health systems,and heterogeneity in sources,model selection,and parameter selection.The majority of evidence supports the benefits of TTFields combined with TMZ for the treatment of GBM patients,but the results of CEAs tend to favor the view that this therapy is not cost-effective.Conclusion Current evidence indicates that TTFields combined with TMZ treatment have better safety and efficacy.However,there is still no consensus on whether it is cost-effective.
