Objective To investigate the health technology assessment reports, analyze publication characteristics and report quality, and explore hot topics in health technology assessment. Methods Web of Science and CNKI databases were searched to collect complete health technology assessment reports from inception to January 2023. SPSS 26.0 software was used to analyze the publication journals, countries, number of authors, assessment types and assessment contents of the assessment reports. The report quality was assessed based on International Network of Agencies for Health Technology Assessment (INAHTA) report criteria (2007 edition). VOSviewer 1.6.11 was used to analyze keywords clustering. Results A total of 216 papers were included, with 158 published by Chinese authors, and a rapid growth trend in the number of reports over past four years. The rate of reports on health technology social adaptability assessment was only 17.13%. Among the Chinese reports, 25 were general health technology assessments, 35 were rapid assessments, and 3 were mini assessments. Among the English reports, 4 were rapid assessments, and 54 were regular healthcare technology assessments. For the 14 items in the INAHTA reporting criteria, the reporting rates were high for the brief summary (98.61%), problem description (94.91%), and results discussion entries (97.69%). However, the reporting rates were low for criteria such as personnel responsibilities, conflict of interest statements, and peer review statements, at 31.94%, 19.44%, and 3.24% respectively. English literature generally exhibited higher report quality. Conclusion In recent years, the volume of health technology assessment reports in China has been increasing, with developments in assessment types and application fields. However, there are also problems with standardization of reporting.
ObjectiveTo investigate the health technologies on diabetes prevention and management used in rural China and the assessment results of these health technologies, and to provide references for the selection and using of health technologies on diabetes prevention and management in rural China.
MethodsWe searched VIP, CNKI, CBM and WanFang Data to collect survey studies and assessment reports of health technologies on diabetes prevention and management in rural China. The search date was up to July 15th, 2014. Two reviewers independently screened literature, and then the qualitative analysis was performed for the included studies.
ResultsA total of 15 studies were included. The results of qualitative analysis showed that:the targeted populations were patients and ordinary villagers who had received the service or treatment of diabetes health technology in rural, as well as the grassroots medical technical personnel and promotion staffs who had developed the health technologies. Diabetes health technology studies in rural mainly included medical personnel health technology related knowledge training. The contents of health technology assessment involved effectiveness, acceptability, economic characteristics, requirements and technical specific property.
ConclusionThere was limited researches on the investigation and analysis of health technologies on diabetes prevention and management in rural China, and evaluation content remains insufficient.
Health Technology Assessment International (HTAi), in conjunction with the International Society for Pharmacoeconomics and Outcomes Research (ISPOR), initiated a joint Task Force and published guideline and a checklist for deliberative processes for health technology assessment (HTA). Currently, there is a lack of guidance for designing and implementing deliberative processes of HTA in China, so this paper performs a detailed interpretation of the guideline and checklist, with a view to providing a reference for China's HTA and deliberative process, in order to promote the dissemination and application of the HTA methodology, and advance the construction of domestic HTA deliberative processes capacity and institutional mechanism.
ObjectiveCapsule endoscopy (CE) has been widely used in the diagnosis of small bowel disease (SBD) in the world. To bring CE into the national health insurance directory, and intensify its popularization in primary hospitals, the government needs high quality health technology assessment (HTA) evidence for decision making. This study was aimed to comprehensively evaluate the effectiveness, safety, applicability and economics of CE in the diagnosis of SBD based on global review, to providing the best currently-available evidence for decision making.
MethodsWe electronically searched The Cochrane Library (Issue 8, September 2013), PubMed, EMbase, INAHTA, VIP, CBM, CNKI and WanFang Data. We screened studies, extracted data, and evaluated quality independently, according to inclusion and exclusion criteria; and then we made final conclusion after comprehensive analysis.
ResultsWe finally included 4 HTAs, 11 systematic reviews (SRs)/ Meta-analyses, 2 randomized controlled trials (RCTs), 5 guidelines, and 10 economics studies for assessment. The results of HTAs, SRs/ meta-analyses and RCTs all showed that, the disease detection rate of CE was higher than that of many other traditional technologies, and that the main adverse event for CE was retention (0.7% to 3.0%), which were consistent with those of the guidelines' recommendations. Besides, the comprehensive results of economics studies showed the superiority of CE compared with other technologies. As the first choice, CE could significantly decrease potential costs, especially when used in outpatients.
Conclusiona) Compared with similar technologies, CE indeed has advantages in diagnostic yield, safety and potential costs in the diagnosis of SBD. However, its application has certain limitations, which still needs to be verified by more high quality evidence about CE diagnosis accuracy. b) It is sug gested that, when the government approves the introduction of CE to hospitals, many factors must be considered, such as local disease burden, clinical demands, ability to pay, and staff configuration. At the same time, it is necessary to standardize training for medical technicians, to reduce economic loss caused by poor technical abilities of medicaltechnicians.
Objective To assess the effectiveness and safety of nine lipid-lowing agents in the national essential drug list (2000) and provide evidence for the adjustment and selection of essential drugs. Methods Based on principles of health technology assessment (HTA) and evidence-based medicine, we searched for all published clinical studies about these drugs from the following databases: MEDLINE (1966-2002.8), The Cochrane Library, EMBASE (1974-2002), CBMdisk (1979-2002.8) and VIP (1989-2002.8), the database of National Center for Adverse Drug Reaction(ADR) Monitoring of China and the database of WHO Uppsala drug monitoring center. Included studies were appraised, analyzed and compared for the reduction of triglyceride (TC) or low density lipoprotein (LDL-C), the prevention for the coronary events and the incidence of ADR. Results The results from comparative trials for lipid-lowing agents showed that the equivalent dose of statins for 25% reduction of LDL-C was atorvastatin 10 mg/d, simvastatin 20 mg/d, pravastatin 40mg/d, lovastatin 40 mg/d, cerivastatin 0.3 mg/d and fluvastatin 80 mg/d. It was difficult to compare fenofibrate with gemfibrozil, acipimox with statins or fibrates based on available data. The study on the primary and secondary prevention of cardiovascular events showed that pravastatin and lovastatin were effective in primary prevention, and long-term use could reduce the incidence of cardiovascular disease.Gemfibrozil could reduce the mortality from coronary heart disease (CHD) but the overall mortality was not changed. Pravastatin, simvastatin, atorvastatin, fluvastatin, gemfibrozil and fenofibrate had a confirmed effect in secondary prevention. Data from large-scale clinical trials and the reports from ADR monitoring center of England, America, Canada and Australia suggested that the statins which had rare ADR were safe and tolerated. Rhabdomyolysis was rare but had a serious adverse reaction associated with statins. The rate of fatal rhabdomyolysis related to cerivastatin was the highest among 6 statins. The safety of simvastatin, lovastatin and atorvastatin was lower than cerivastatin but higher than simvastatin and atorvastatin. The number of ADR reports of fenofibrate was fewer than that of gemfibrozil. Conclusions At present, the best evidence focused on pravastatin, simvastatin and lovastatin are widely used and have a confirmed safety and efficacy. Atorvastatin, fluvastatin and fenofibrate still need more data to confirm their effects on coronary heart disease prevention. The drugs which were shown to be inferior or insufficient evidence are cerivastatin, gemfibrozil and acipimox.
Objectives To evaluate the effectiveness, safety, applicability and economy of psychological assessment instruments including checklists, questionnaires and scales used in population exposed to earthquake.
MethodsWe searched PubMed, EMbase, The Cochrane Library, CBM, CNKI, VIP, WanFang Data, and CiNii databases, as well as special websites about earthquake and disaster management from inception to July 30th, 2014 to collect studies related to psychological assessment of population exposed to earthquake in the first month after quake. A descriptive analysis was conducted to analyze the positive detection rate of psychological problems, rate of informed consent, and effective response rate in population exposed to earthquake, as well as the cost of psychological assessment.
ResultsA total of 67 studies were included which involved 4 instruments including Symptom Checklist 90 (SCL-90), Self-Reporting Questionnaire-20 (SRQ-20), Chinese Psychosomatic Health Scale-134 (CPSHS-134) and 12-item General Health Questionnaire (GHQ-12). SCL-90 was the most commonly used scale. Forty-five studies reported the positive detection rate of psychological problems in population exposed to earthquake. The positive detection rates by using SCL-90, GHQ-12 and SRQ-20 were 8.6% to 77.8%, 65.6% to 89.9% and 65.6% to 89.9%, respectively. Informed consent was reported in 27 studies, and effective response rate was reported in 20 studies with the highest one 99.56% for CPSHS-134. No study reported the cost of psychological assessment.
ConclusionSCL-90, RQ-20, CPSHS-134 and GHQ-12 are mainly used instruments for assessing psychological problems in population exposed to earthquake in the first month after quake. The reporting of important information related to effectiveness, safety, applicability and economy of psychological assessment instruments is insufficient and not standardized. A concise and authoritative psychological assessment instrument for population exposed to earthquake is warranted.
ObjectiveTo utilize a rapid health technology assessment to evaluate the efficacy, safety and cost-effectiveness of the MitraClip device for patients with severe mitral regurgitation (MR). MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data, CBM and the CRD databases were electronically searched to collect clinical evidence and economic evaluations on the efficacy, safety and cost-effectiveness of the MitraClip device for patients with severe MR from inception to May 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies; then, descriptive analyses and data summaries were performed. ResultsA total of 33 studies, involving 4 HTA reports, 3 RCTs, 16 systematic reviews or meta-analyses, and 10 economic evaluations were included. In the evidence comparing MitraClip and surgery, most of the literature showed that the MitraClip group had higher postoperative residual MR, fewer blood transfusion events, and fewer hospital days. We found no significant treatment effects on 30-day adverse events and mortality, and the 1-year and above survival rate. In the evidence of MitraClip versus medical therapy alone, all included studies showed that MitraClip benefited mid-term and long-term survival and reduced the incidence of subsequent cardiac hospitalizations. Economic evaluations showed that the clinical benefits were cost-effective in the setting of their health service systems. ConclusionThe available high-grade clinical evidence shows that MitraClip is effective and safe to some extent, and has cost-effectiveness compared with traditional treatment in other countries. However, the real-world effectiveness and cost-effectiveness of the MitraClip need to be tested in the Chinese population and health-care setting.
Health insurance system has been proved to be an effective way to promote the quality of health service in many countries. However, how to control health expenditure under health insurance system remains a problem to be resolved. Some developed countries like UK, Canada and Sweden linked their health technology assessment results with decision making and health insurance management, and made prominent achievements in both expenditure control and quality improvement. China is carrying out its health system reform and running a new health insurance project. Using the experiences of other countries is undoubtedly of great importance in developing and managing our health insurance system.
Objective To comprehensively summarize and analyze the status quo, assessing contents and problems of the assessment studies on appropriate health technology in China. Methods With the search terms and strategies predefined by repeated discussion and pre-retrieval, all literature on appropriate health technology assessment in China published from October 1949 to March 2012 were searched in the following databases: CBM, VIP, CNKI and WanFang Data. According to the inclusion and exclusion criteria, two reviewers independently screened literature, and extracted and cross-checked data. Disagreements were resolved by discussion or by involving a third researcher. The qualitative synthesis method was used to analyze the studies. Results Among total 174 included studies, 117 were cross-sectional. Targeted populations were patients and community residents who had received the service or treatment of appropriate health technology, as well as the grassroots medical staffs and workers from marketing organization who had used or carried out the appropriate health technologies. Appropriate health technologies mainly contained four fields of appropriate health technology: traditional Chinese medicine, western medicine, family planning services and community health services. Most types of diseases involved in those technologies were circulatory system diseases, and high blood pressure was highly concerned. The contents of appropriate health technology assessment mainly included 6 aspects: effectiveness, acceptability, economic characteristics, requirements, safety and technical specific property. The results of the included studies indicated that, most assessments focused on just one aspect, and were lack of comprehensive evaluation. The indexes used in each assessment covered a far too wide range, and was lack of unified index and standards. Conclusion Current studies show that the fields of appropriate health technology assessment distribute widely; the assessment content is simple and lack of comprehensive evaluation; the assessment index system has no unified standard; and the study design methods are different and lack of high quality study design. So it is necessary to conduct high quality assessment studies, establish scientific assessment index system, and systematically assess appropriate health technology, so as to provide more scientific basis for health decision makers.
ObjectivesTo explore the using status of psychological assessment instruments including checklists, questionnaires and scales after earthquake, so as to provide baseline data for establishing a standard method and process in developing earthquake-related population psychological screening and assessment instruments in future.
MethodsWe searched WanFang Data, CNKI, VIP, PubMed, EMbase, The Cochrane Library and CiNii databases, as well as special websites about earthquake and disaster management from inception to July 30th, 2014 to collect studies evaluating the population psychological health conditions with assessment instruments after earthquakes. The earthquake countries/regions, the main assessment institutions, the time of assessment, the objects of assessment, and the instruments used were analyzed.
ResultsA total of 794 studies were included, of which 87.4% were from mainland China, and 78.0% were related to the Wenchuan earthquake. Most of assessments were conducted by universities (47.9%) and hospitals (46.9%) in Sichuan, Beijing and Guangdong provinces of China. The psychological assessments conducted in the first year after quake were found in 537 studies (67.6%), of which 244 studies (45.4%) reported the psychological assessments results in the first month after quake. The top five assessment objects were children/teenagers, survivors, wounded, military rescuers, and medical staff. In the 794 included studies, a total of 217 instruments were used. In the 244 studies reported the assessment results in the first month after quake, a total of 73 instruments were used. 122 of the 244 studies reported only one instrument was used, and the other 122 of the 244 studies reported two or more instruments were used. Most of the instruments were translation versions and developed for mental disorders. The top 5 instruments were Symptom Checklist 90, Self-Rating Depression Scale, Self-Rating Anxiety Scale, PTSD Checklist-Civilian Version and Impact of Event Scale Revised, respectively.
ConclusionAll the psychological assessment instruments are not developed for assessing earthquake-related psychological health problem, so a simple, economic, feasible and specialized instrument for earthquake-related population should be developed. It's needed to organize professionals to design a local guideline and training material for earthquake survivors and rescuers, and to establish a standardized, sustainable normal training base and trainer's team, so as to standardize the psychological aid work.
