ABSTRACT
Objective:To get comprehensive understanding of the registration characteristics of global clinical trials of coronavirus disease 2019(COVID-19) based on the ClinicalTrials. gov and the Chinese Clinical Trial Registry (ChiCTR).Methods:The clinical trials of COVID-19 in the ClinicalTrials.gov and ChiCTR were retrieved. The search start time was unlimited, with deadlines of 14 December, 2020 and 19 March, 2021, respectively. The registration numbers, registration submitted time, country/region distribution, recruitment status, study types, number of recruits, research phases, and other aspects were analyzed by using bibliometric methods.Results:As of March 19, 2021, there were 775 clinical trials in ChiCTR. As of December 14, 2020, there were 4 137 clinical trials in the ClinicalTrials.gov, and 3 157(76.31%) of the clinical trials recruited subjects who were aged≥18 years old. There were 2 347 intervention trials and 1 759 observational trials. The intervention measures mainly included drugs, biologics and medical devices. The numbers of recruits were 110(48, 308) cases for interventional studies, and 300(100, 1 000) cases for observational trials. The interventional research phases were mainly phaseⅡ (570 items) and phase Ⅲ (358 items). Totally, 50.33%(2 082/4 137) of the clinical trials were under recruitment, 13.10%(542/4 137) had been completed. Among the interventional studies, 729(31.06%) were multi-center studies, with the center numbers of 5(2, 15).Conclusions:At present, there are a large number of clinical trials with various intervention measures in the world. However, the number of recruits is unreasonable, and multi-center study with multi-agency cooperation is insufficient.
ABSTRACT
Objective The paper aims to analyze the effectiveness and problems of health personnel construction in China since 2012,provide reference for promoting the construction of health professionals.Methods Using national data from China health statistics yearbook,adopted the methods of descriptive statistics and literature research and so forth.Results The construction of health personnel has been continuously strengthened in China,the structure and distribution of health personnel have been further optimized,the medical service capabilities have been improved.However,there are still inappropriate or imbalanced situations.Conclusions The construction of key personnel such as primary health personnel and urgently needed personnel need to be further strengthened;promote the construction of health service personnel to meet new health needs;continue to improve the construction of high-level and management personnel to play a leading role.
ABSTRACT
Objective To analyze the management experience of Swedish medical research funding,and provide reference for further rationalization of medical research investment management in China.Methods Literature research method,descriptive statistics and other methods were used to systematically sort out the source of Swedish medical research funding,and specifically analyze the capital investment and distribution in medical fields in the past ten years.Results The Swedish government 's budget in the UO9 (health,medical and social care) field is steadily increasing.The annual average budget accounts for 7.14％ of the total government budget.There are scientific management methods for fund allocation.The appropriation projects are mainly divided into three main directions including public health categories,health care and social care.Conclusions Taking into account of the problems existing in the investment and distribution of medical research funds in China,this paper proposes to explore the capital investment mode suitable for China's national conditions,enhance the targeted investment of funds in medicine,and establish a scientific and efficient fund investment management mechanism.
ABSTRACT
Objective To study the hotspots and frontiers in research of medical big data using CiteSpace.Methods The papers on medical big data covered in Web of Science were analyzed using bibliometrics in combination with CiteSpace.Results The achievements in research of medical big data have rapidly increased since 2012.The nodes in research of big data, system, care, medicine and personalized medicine were bigger.The burst value in research of quality, children and mapreduce was higher.Conclusion The number of current researches in medical big data is greater in medical big data technology, precision medicine, medical and health big data management, medical big data privacy while mapreduce, ontology and hadoop are the frontiers and future trend in research of medical big data.
ABSTRACT
Objective To analyze the hot spots and frontiers in domestic and foreign precision medicine with CiteSpace. Methods The CNKI and WOS-covered papers on precision medicine were analyzed by bibliometrics combined with CiteSpace. Results Domestic precision medicine got off in 1992 and scholars became interested in it from 2010 . Foreign precision medicine started in 1985 and studies on it increased rapidly from 2006 . The node of precision medicine was the largest in China with a rather high value of gene mutation, US president Barack Obama ( precision medicine program) , personalized medicine, gene chip, genomics and pharmacogenomics whereas the node of personalized medicine, cancer and breast cancer was the largest with a rather high value of precision medi-cine, pharmacogenomics and pharmacogenetics. Conclusion The number of domestic and foreign papers on US president Barack Obama ( precision medicine program) is rapidly increased and pharmacogenomics is their common frontier. However, cancer is highly concerned in foreign countries.
ABSTRACT
Medical big data, an important strategic source of basic data for a country, will be applied in precision clinical diagnosis and treatment, decision-making support, disease monitoring, early warning and management, and public health service. The application of medical big data technology in our country is to be improved at pres-ent. How to realize the smooth transition of traditional medical data to a big data system and the added value of data by data mining and analyzing is an important problem needing to be solved immediately. The key functions, inclu-ding the general frame work and data center frame work of medical big data application information system, were thus planned and designed in this paper by constructing the regional application technology and engineering labora-tory for medical big data.
ABSTRACT
Objective Establish an objective and fair evaluation index system for the implementation effectiveness of the National Major New Drug Development Program of China.Methods Based on literature review and Delphi method,the framework of the evaluation index system was built and analytic hierarchy process was applied to determine the priority of each indicator of the system.The objectiveness and validness of the results were assured by determining expert activeness coefficient,authority coefficient,indicator rationality,and by applying consistency check.Results A targeted and systematic evaluation index system was constructed for the National Major New Drug Development Program,and through expert consultation and analytic hierarchy process,the factor of product result was considered of the highest weight of 39.03％,followed by technical result,theoretical result and organization and management result.The evaluation index system suggested that product result and technical result are two relatively more significant factors to be considered during evaluation.Conclu sion After consultation on expert opinions,the evaluation index system for the National Major New Drug Development Program was constructed with each factor been assigned with a scientific and rational weight,and this will provide a guideline for the decision making of program administrators and evaluation practice.
