Objective According to health technology assessment (HTA) methodology, to assess the efficacy and safety of different doses of metoprolol in the treatment of atrial fibrillation (AF). Methods Based on the principles of HTA, we searched some important medical databases including MEDLINE, EMBASE, The Cochrane Library and CMCC, as well as several national special heart disease databases and side effect centers. We selected eligible studies based on the inclusion and exclusion criteria and critically assessed their quality. Results Intravenous metoprolol 10 mg - 15 mg could control rapid ventricular rate in patients with chronic AF. On either rest or exercise, oral metoprolol 150 mg/d had a better control of rapid ventricular rate than 50 mg/d in patients with chronic AF. For preventing postoperative AF (POAF), the intravenous metoprolol 20 mg group and the 30 mg group could decrease the incidence of POAF compared to the 10 mg group. Oral metoprolol 150 mg/d was more effective than 100 mg/d in preventing POAF. In addition, intravenous metoprolol therapy was well-tolerated and more effective than oral metoprolol therapy in preventing atrial fibrillation after cardiac surgery. Results from several national side effect centers demonstrated that the incidence of adverse reactions associated with metoprolol was low. Conclusion Present evidence showed that high dose of metoprolol was superior to low dose in treating AF, however, the evidence available is insufficient. It is suggested that adequate evidence through further studies are needed. The safety profile of different doses of metoprolol is similar.
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.
ObjectivesThe primary objectives of this rapid health technology assessment (RHTA) were to assess the safety and effectiveness of Da Vinci surgical system compared with traditional e surgeries, so as to provide the currently-available best evidence for health decision makers and clinical workers.
MethodsA comprehensive search of electronic databases (EMbase, PubMed, The Cochrane Library, Web of Science, CNKI, VIP, CBM and WanFang Data) and relevant professional HTA websites were conducted from inceptionto October 9, 2012. Two reviews independently screen literature according to the inclusion and exclusion criteria, extracted data, and assess the quality of included studies. The data based on secondary studies were reported, and a final recommendation and its level was made based on assessment outcome.
ResultsA total of 21 studies were included, encompassing 7 HTAs and 14 systematic reviews/metaanalyses. The included studies involved radical prostatectomy, hysterectomy, nephrectomy, coronary artery bypass graft, and gastric fundoplication. Though the included HTAs and systematic reviews/meta-analyses focus on different diseases, the outcomes showed significant differences existed between Da Vinci surgical system and other routine surgery in clinical effectiveness and safety of different diseases. Compared with routine surgery, Da Vinci surgical system shortened hospital stay; decreased operation conversion rates, blood loss and blood transfusion rates during surgery; but it increased operative time. Besides, compared with traditional laparoscopic surgery, Da Vinci surgical system shortened operation time and hospital stay, and decreased operation conversion rates, blood loss and blood transfusion rates during surgery.
ConclusionCurrent evidence shows that the clinical effectiveness and safety outcomes of Da Vinci surgical system differ in diseases. Currently, most included HTAs and systematic reviews/meta-analyses are based on observational studies, relevant prospective randomized controlled trials lack, and the evidence is graded as low quality, health decision makers are suggested to apply this evidence with caution on the basis of comprehensive consideration.
ObjectiveTo construct rapid health technology assessment (RHTA) reporting norms, with a view to providing methodological references for RHTA research and reporting. MethodsBased on the preliminary pool of entries constructed by the literature research results, and taking into account the characteristics of RHTA, a Delphi expert correspondence questionnaire was designed, and 25 experts in the field of HTA were selected to conduct multiple rounds of expert correspondence. By calculating the expert authority coefficient and opinion coordination coefficient, combined with the average value of the entry score, coefficient of variation and full score ratio, the entries were selected to form the list of RHTA report specifications. ResultsThe positive coefficient of experts in both rounds of investigation was 100%, the expert authority coefficient in the first round was 0.858, and the expert authority coefficient in the second round was 0.838. The Kendall coordination coefficient in the first round was 0.169, and in the second round it was 0.081. According to the correspondence of 2 rounds of investigation, the final formation included 8 aspects, 26 first-level entries and 18 second-level entries in the list of RHTA report specifications. ConclusionThis study constructed the RHTA report specification, which is both scientific and operable, providing a reference for RHTA report writing.
Hospital-based health technology assessment (HB-HTA) refers to the practice of health technology assessment for hospital management decision-making based on the actual situations in hospitals. It includes processes and methods of health technology assessment carried out in and for hospitals. Under the background of comprehensively promoting the reform of public hospitals in China, HB-HTA is undoubtedly an important scientific method to enhance the fine management of public hospitals and implement the policy of medical reform. This paper introduced the concept, the international and domestic development status, the characteristics of HB-HTA, and put forward the scheme of development of HB-HTA macroscopically, so as to promote the popularization and applications of HB-HTA in China.
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.

Health technological innovation has helped to improve health care delivery and patient outcomes. However, the proliferation of health care technology has accompanied burgeoning health care costs and evoked social, ethical, legal, and political concerns. Health technology assessment (HTA) is the systematic evaluation of properties, effects and/or other impacts of health care technology. The main purpose of HTA is to inform persons of technology-related policy making in health care. There is great variation in the scope, selection of methods and level of detail in the practice of HTA. This paper will introduce the basic concepts and methods of HTA in order to help those who are interested in conducting HTA.
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.
Objective To investigate the feasibility of health technology permission (HTP) for widely used, high cost and risk technologies based on evidence of health technology assessment (HTA) from the perspective of Ministry of Health (MOH). Method With reference to experiences of HTA and evidence-based health administration in developed countries, four HTA and EBM entities have been established in China, which promoted and disseminated HTA. Three technologies-Bank of Haematopoietic Stem Cell from Umbilical Cord, Assisted Reproductive Technology (ART) and Sperm Bank-were piloted to assess, which provided quality evidence to assist MOH in formulating the Regulation for Permission on Health Technology. Results A set of technologies such as medical equipment, clinical techniques and screening technology for disease prevention and control have been assessed. Several regulations for permission on individual health technologies have been prepared to guide certification of professionals and health institutes. These include Regulation of Bank of Haematopoietic Stem Cell from Umbilical Cord, Regulation of Assisted Repreduction Technology and Management of Human Sperm Bank. Conclusions Although we have possessed a pre-requisite to establish a set of managing system for evidence-based permission of health technologies, an efficient infrastructure to run this system should be established and improved.
